Greenhouses made of PVC pipes. How to make a greenhouse from plastic pipes with your own hands? Do-it-yourself foundation pouring

Setting up an inexpensive and easy-to-implement greenhouse on a property is the dream of any summer resident or owner of a country house. Today this is possible thanks to the construction of a greenhouse made of PVC pipes. The structure turns out to be reliable and durable, which is why it is gaining increasing popularity among summer residents.

Features of greenhouses and greenhouses made of PVC pipes

Growing vegetables indoors is becoming increasingly popular. The designs of greenhouses and greenhouses are very diverse, and they are often made from scrap materials left over from building a house. One such material is water pipes made of polyvinyl chloride. This material is relatively cheap, and working with it does not require special skills, which allows you to install greenhouses with your own hands.

To build a greenhouse from PVC pipes you will not need any special tools or special skills, which means this type of construction is available to self-construction even for summer residents with little income

Pros and cons of PVC pipes as a material for a greenhouse

The positive aspects of using such material are:

The only and main disadvantage of using PVC pipes to build greenhouses is that the structure is quite light. In areas with strong winds, it needs to be reliably strengthened at the installation site. In this case, it is better to use polycarbonate as a greenhouse covering, since it is more reliable and durable than film. The material is noticeably more expensive, but all costs are recouped by long service life.

Greenhouses that are not planned to be dismantled winter time, it is better to install on a foundation, which will ensure the strength and durability of the structure Polycarbonate is convenient to transport over any distance; it is fire resistant, resistant to many chemical elements and has excellent thermal insulation The dome design of the greenhouse contributes to better penetration sunlight For year-round cultivation flowers will be required winter greenhouse, which will be equipped with a special heating system Building a house allows you to make maximum use of the planting area; even tall plants can be planted along the walls Warm air in tent structure accumulates under the roof and is removed thanks to the windows, which provides better ventilation for plants Due to its location next to a heated room, more comfortable conditions for plant growth are created. Plastic is much more resistant to rotting and corrosion than, for example, wood or metal; the properties of this material make it possible to avoid the need for mandatory treatment of product elements with protective substances

Construction of a greenhouse from PVC pipes with your own hands

Preparatory work for installing a greenhouse on the site should begin with the development of a preliminary design. In this case, the following circumstances must be taken into account:

1. Consider a method for attaching the structure to the ground, taking into account the climatic features of the area, especially the direction and strength of the prevailing winds.
2. Develop methods for connecting individual parts using standard fittings for the selected type and size of pipes.
3. Calculate the need for basic materials for load-bearing structure and the supporting part of the greenhouse.
4. Calculate the need for covering material and fasteners.
5. Determine the necessary tools and equipment.
6. Buy everything you need.
7. Prepare all parts for assembly, guided by the design.

PVC is much cheaper than metal and high-quality wood, and is not inferior to them in functionality

Selection of materials

The range of materials used is small:

1. For the frame - pipes from PVC diameter 25 millimeters with a wall of at least 4.2 millimeters.
2. Reinforcing steel bars with a diameter of 12–14 millimeters at the rate of 160–170 centimeters for each arc.
3. Perforated metal strip with a width of 40 millimeters.
4. Edged softwood boards measuring 40x100 millimeters, the quantity is determined based on the selected dimensions of the greenhouse.
5. Polyethylene film with a thickness of at least 200 microns, it is better to use reinforced material.
6. Wooden planks made from boards 15–20 millimeters wide, 60 mm long, depending on the place of application - for attaching the film to the frame of the end walls.
7. Self-tapping screws with a diameter of 5 millimeters for fixing arches, 60 long - at the rate of 4 pieces per arch.
8. Wooden blocks for making the frame of the end walls measuring 40x40 millimeters are cut at the installation site.
9. Antiseptics and fire-resistant impregnation for wooden parts.
10. Pipe fittings according to the project.
11. Door hinges - 4 pieces (for two doors).
12. Door handles - 4 pcs.

Calculation of greenhouse dimensions

To calculate the materials, you need to decide on the dimensions of the greenhouse itself. Typically, a greenhouse has two beds with a passage between them. The width of the beds is 0.8–1.1 meters. The width of the passage should allow easy movement with buckets and other garden supplies, including a wheelbarrow. The path should be made 0.6–0.8 meters wide. Thus, the width of the greenhouse will be 2.2–3 meters.

The length of the greenhouse depends on the needs of the owner and the vegetable crops that are planned to be grown.

Typically, the length of the greenhouse is from three to six meters. A greenhouse of shorter length will be useless, and a longer one will require more durable materials for construction.

The design must be selected with a minimum number of docking nodes, as they significantly weaken stability

The height of the greenhouse should allow you to move freely around it. You also need to take into account that there should be at least 50 cm of free space above the plants.

Another important parameter- length of the arc made of PVC pipes.

Table: arc length for standard greenhouse sizes

If the dimensions of the greenhouse are not standard, then the arc length is calculated using the formula: L= 3.14 * (h + B/2)/2. Where B is the width of the greenhouse, h is the height, L is the length of the arc.

Installing the base

The frame of the greenhouse is usually installed on wooden frames. To make them you will need a board made of coniferous wood measuring 100x40 millimeters. The quantity depends on the selected greenhouse size. It is allowed to splice the beam along its length for frame sizes of more than six meters.

Suitable for greenhouse support frame pine board dimensions 40x100

Wooden base installation steps:

1. The boards are laid out at the installation site and joined at the corners into a tenon. Next, the dimensions of the quadrangle are carefully measured and the diagonals are aligned so that the structure does not have distortions. After this, additional fastening is installed using galvanized steel corners with self-tapping screws. They are placed on the inner surface of the corner. The final fixation of the support frame is performed with four pins driven into the ground at the corners close to the base. The length of the pins should be 45–50 centimeters, the material is corrugated reinforcing steel with a diameter of 12 millimeters.
2. An obligatory part of the base are pins made of reinforcing steel with a length of about 75 centimeters and a diameter of 12–14 millimeters. The size is indicated based on the conditions of use for arcs of a PVC pipe of a standard size of 25x4.2 millimeters, the internal opening of which is correspondingly 16.6 millimeters.
3. The pins are immersed in the ground so that an end 35–40 centimeters high sticks out of the ground, and the distance to the support board is 4–5 millimeters. The number of pins should be equal to twice the number of arcs according to the project. The distance between them should be at least a meter.

The length of the reinforcing bars must be at least 75 centimeters

Installation of the greenhouse frame

The procedure for assembling the frame:

1. Each piece of pipe intended for arches is put on a pin on both sides of the base. The lower end of the pipe should be level with the bottom edge of the base board.
2. Fastening is done to it using a metal strip and self-tapping screws. After installing the last arc, the supporting frame can be considered ready. All that remains is to install the longitudinal stiffeners. They are mounted between each arc along the entire length of the greenhouse.
3. One rib is made from a solid pipe and is installed along the upper axis of the dome. Fastening is done with construction clamps. The remaining two ribs can be installed in the middle of the arcs on each side.

The described algorithm is valid for a tunnel greenhouse. If a gable design is selected, all connections can be made using standard fittings.

It’s better to buy pipes and fittings as a set - in this case you don’t have to worry that their diameters won’t match

End walls

For the end walls, frame structures are used, made from a wooden block measuring 40x40 millimeters. One of the options is used as a covering material:

• polyethylene film;
• cellular polycarbonate 4 or 6 millimeters thick;
• waterproof plasterboard;
• waterproof plywood, as well as any other sheet material with waterproof properties.

To install a door, you need to make a door frame with an opening of at least 90 centimeters so that it can pass through garden wheelbarrow. The vestibule itself is rectangular in shape with one lintel in the middle. Inside each opening you need to install jibs to impart rigidity to the structure. The canvas is made of the same material as the wall. The door must be hung on standard hinges and equipped with two handles on different sides. It is more convenient to equip doors on both end walls. In addition to the door, vents must be installed on the end walls of large greenhouses.

The door must correspond to the dimensions of the greenhouse structure and be convenient for passage

To protect the greenhouse from pests from outside, it is advisable to install a mosquito net on the openings. On the door - in the form of a light vestibule, on the windows - tightly blocking the opening.

Step-by-step instructions for installing a greenhouse

The technology for constructing such a structure is extremely simple, but requires strict sequential execution. In practice it looks like this:

1. We install the support base under the frame. We fix the frame on the ground surface, ensuring that its shape remains unchanged along the horizon. After installing the pins, check the horizontalness of the frame and, if necessary, level it using shims and counter wedges. The gap between the soil and the board must subsequently be eliminated by adding earth.

   Reliable fixation of the greenhouse frame with metal pins at the inner corners of the frame is necessary.

2. Along the perimeter of the support frame, we drive metal pins into the ground using a sledgehammer. After completing the immersion to the required depth, we remove the burrs formed on the upper end and dull the sharp edges so that they do not subsequently damage the plastic pipe from the inside.

   It is advisable to wrap the fittings with tape so that they do not move inside the PVC pipes

3. We pour sand around the perimeter of the frame, finally securing it.

   When securing the frame with sand, you can immediately lay out paths and fences for the beds

4. We simply put the pre-prepared pipes for the frame arcs onto the pins with the end holes. The ends of the pipes should be at the level of the bottom edge of the board.

   Instead of reinforcing pins, you can use special metal plates with pegs, which are attached to the base of the greenhouse with self-tapping screws

5. We fasten the pipes to the base with a steel tape or strip with holes for fastening. But it is more reliable to use loops made from a standard strip 4 millimeters thick. Most likely, it will not be possible to purchase such parts in a factory-made version, so they must be manufactured independently with anti-corrosion surface treatment. Installation is carried out using a screwdriver and self-tapping screws with a diameter of at least 5 millimeters.
   

   Reliability of fastening is ensured by the tight grip of the pipe strip

6. Next, we make the frames of the end walls of the greenhouse, using wooden blocks cross section 40x40 millimeters. They are not assembled separately, but are manufactured locally with simultaneous attachment to the outer arc of the frame. It is better to assemble using self-tapping screws rather than nails.

   End walls are mounted on site, not separately

7. We attach the braces of the end walls of the greenhouse to the PVC arches using a hole at the end of the bar. The hole must exactly match the diameter and shape of the pipe.

   The hole for the arc on the outer end strips is made at a bevel; you need to accurately measure the angle of the arc, draw it on the edges of the bars and mark the place of the cut

8. The verticality of the end wall is ensured by jibs and is controlled by a plumb line. This operation is intended only for precise installation; power reinforcement with wind jibs is carried out upon completion of installation.

   The use of a jib ensures the geometry of the frame during installation

9. Upon completion of the assembly of the end wall frame, we install the upper stiffener. It is made from the same PVC pipe. If necessary, on long greenhouses you need to connect several products with a standard coupling from a set of fittings. We attach the stiffener to the intermediate arches using plastic construction clamps. At each intersection we install two such ties crosswise.

   For the reliability and strength of the structure, it is necessary to fasten the pipes with construction clamps

10. One stiffening rib is clearly not enough for such a design, especially in areas with strong winds. Therefore, between each arc at a height of about 1.3–1.5 meters we install additional elements fastenings They can consist of one long piece, but it is better to use cut pieces from the same pipe. We connect the thrust elements with the frame arches using special connecting parts made of thermoset with a wall thickness of 3 millimeters.

    A wooden plank with a holder profile for covering material can be attached to PVC pipes at a distance of about 50 cm from the ground. This will make it possible to ventilate the greenhouse from below

11. Separately, we assemble the door, which we place on the hinges.

    As a door, you can use wooden frames from old windows, but instead of glass it is better to stretch the film or sheathe the frame with polycarbonate sheets

12. We fix the film wooden planks using nails 3.5x50 millimeters. The film is attached with longitudinal tension along the length on one side of the frame to the supporting frame, after which the operation is repeated along the opposite edge. The tension in this case should not be excessive. The distance between the nails should be 15–20 centimeters.

    The film must be attached with a slight sag

13. Installation of the film on the end walls is done last. It is no different from the main shelter. We attach the film using strips to all the elements of the wall frame from the outside, and cut off the excess.

    OSB boards are easy to install and affordable

Features of using polycarbonate as a coating

Execution finishing coating made of this material has some features regarding installation technology. For example:

1. The distance between adjacent arcs in the frame must correspond to the width of the polycarbonate sheet, which, in the standard version, is 2.1 meters. That is, the axes of the arcs should be one meter apart from each other.
2. Considering that it is impossible to attach polycarbonate to the arches, it must be installed using metal ties across the frame. Therefore, the sheets are laid with an overlap of 10 centimeters. The screed is installed in the place of overlap.
3. The multiplicity of length options for such a greenhouse is 2 meters, otherwise one sheet will need to be cut lengthwise. However, this is not so scary, because the trim can be used to seal the end walls and install doors and vents.

In polycarbonate, you need to drill holes larger than the diameter of the screws by 1.5–3 mm. This will create a compensation gap, which, when the sheet expands, will prevent the greenhouse from being destroyed and will leave the polycarbonate intact.

It is necessary to note several features when installing a greenhouse that will be useful for beginners:

1. To install a greenhouse, you need to choose the most illuminated place on the site, not shaded by bushes and trees.
2. For the first greenhouse, it is better to choose a design with PVC pipes, as it is the simplest to implement and affordable.
3. The installation of the film covering should be done in warm weather, literally 5–7 days before planting.
4. When the weather is hot, the doors and windows in the greenhouse need to be opened for ventilation. Heat in combination with high humidity is harmful to most plants.
5. In areas with heavy snow, it is better to remove the film from the greenhouse for the winter. This will help avoid deep freezing of the soil, retaining beneficial microorganisms and moisture in the soil.
6. For the winter, in a greenhouse with the film not removed, you need to install supports under the frame.
7. Polyethylene film can be replaced with more modern materials- bubble or reinforced film, as well as agrospan coating.
8. It is necessary to remove the soil layer from the greenhouse and cover the surface with a waterproofing film. This will get rid of weeds and pests in the greenhouse. The fertile soil brought in and filled will give an excellent harvest.
9. On a concrete foundation, such a greenhouse can also be used for growing seedlings.
10. Particular attention should be paid protective coatings for wood. It is better to coat parts in contact with the ground bitumen mastic, for the rest, any means are suitable, starting from ordinary drying oil.

Using PVC pipes, you can build various forms of greenhouses with closed ground, ranging from seedling boxes to a winter garden. In any case, these devices will be relatively inexpensive and effective.

By growing vegetables in a greenhouse, you can get your harvest much earlier than when harvesting in a regular garden.

A greenhouse with a lightweight design made from PVC pipes is quite capable of providing the owner with fresh, environmentally friendly vegetables and helping to grow good seedlings for open ground on the site. Due to the ease of construction and the low cost of the materials used, greenhouses made of PVC pipes have become quite popular among summer residents.

Build a greenhouse with your own hands from plastic pipes can be done with ease and without large financial expenditures. However, it doesn’t hurt to learn about possible nuances.

Advantages and disadvantages of plastic pipes

Every day, polymers are increasingly replacing wood, glass and other materials from the industrial sector. The plastic is durable and lightweight and is not corroded by mold. The material is not afraid of fumes, chemical substances and moisture.

Plastic structures last longer than products made from other materials, as they can easily withstand negative environmental influences.

The disadvantage is the cost of greenhouses from manufacturers, as well as the sizes, which do not in all cases meet the needs of summer residents. However, there is no need to be upset, since you can build a high-quality greenhouse yourself.

The highest quality and most affordable greenhouses are those with a frame structure made of profile pipes. However, if the budget is limited or there is no desire to overpay for the installation of such a greenhouse on the site, then you can build a structure from plastic tubes. This product has a number of advantages over more expensive analogues. The main advantages of the material include:

1. Low cost. Aluminum buildings will cost much more.
2. Easy to install and dismantle. This makes it possible not only to independently choose the dimensions of the structure, but also to dismantle it and store it in a garage in the winter. Without special skills, you can build a greenhouse from pipes in one day.
3. Light weight. This quality is often mistaken by experts as the main drawback of the product.
4. Mobility. The building can be easily moved from one place to another.
5. Versatility of production. During the construction and design process, it is possible to choose any parameters and dimensions, taking into account the characteristics of the estate.
6. Resistance to negative atmospheric influences.
7. Long service period.
8. Great looks. You can build a structure yourself, the appearance of which will not be inferior to the factory product.
9. Environmental friendliness. Plastic is a safe and environmentally friendly material. Accordingly, nothing will threaten the crop and soil.

The only drawback of plastic buildings is that factory-made structures are not always suitable for the available site. If you want to build a product of complex shape, then you should know that the structure will be unstable in gusts of wind.

Design dimensions

In most cases, two beds are placed in the greenhouse, which are separated by a path.

Beds in a greenhouse made of plastic pipes

The width of the beds is on average 0.9–1.1 m - this makes it possible to plant plants in two rows with the required spacing and provide unobstructed access to them.

The width of the path should be such that it is possible to move comfortably with a bucket and other dacha equipment, including a wheelbarrow.

Correct aisle width

The optimal width of the path is 0.7–0.8 m. In this case, the width of the structure will be 2.3–3 m.

The length of the product will depend on the needs and requirements for the location of the vegetables that are planned to be grown. Planting rates per 1 m2 can be seen in the table below:

Using the table you can determine the length of the building. Typically, structures with a length of 4–6 m are made, since it is impractical to install a greenhouse of smaller dimensions, and for buildings of greater length it will be necessary to use materials of increased strength. Construction technology will also differ.

It is important to know: if you plan to use polycarbonate as the material for covering the structure, then it is recommended to choose a length that is a multiple of the width of the sheets (2 m). In this case, you can avoid unnecessary pieces.

The height of the building should allow you to comfortably move around it. It is worth knowing that there should be at least 50 cm of free space above the plantings.

Correct greenhouse height

This place will accumulate warm air and air exchange occurs during the ventilation process. If you plan to grow low-growing vegetables, then a height of 1.9–2 m is sufficient. For tall crops, the minimum greenhouse height is 2.3–2.4 m.

The frame of the tube structure forms half a circle. The width of the product is the diameter of this parameter. If the diameter is known, then the radius can also be determined. The values ​​allow you to calculate the length of the district. This can be done using the following formula:

L = 2πR = πD, where L is the circumference, R is the radius, and D is the diameter. The number π is 3.14.

For example, if you plan to make a greenhouse with a height of 200 cm, then with a correct arc the width should be 400 cm. In this case, the diameter of the circle is 400 cm and the radius is 200 cm.

Accordingly, the length of the district: L = 2 x 3.14 x 2000 = 12560 mm. Only half the circle is needed, so the length of the arc is calculated as follows: 12560 / 2 = 6280 mm.

The arc consists of 2 tubes and a cross, so the resulting value must be divided again: 6280 / 2 = 3140 mm. This will be the size of the pipe.

Drawing of a greenhouse made of pipes

There are many ready-made diagrams that will help you assemble a greenhouse yourself. If you choose a simple option, you can assemble the structure in a few days. The first step is to prepare a design drawing, with which you can easily calculate the required pipe footage. The volume of materials depends on the dimensions of the building.

The greenhouse assembly diagram includes the installation of sides for fencing.

An example of a drawing of a greenhouse made of plastic pipes can be seen in the figure:

Drawing of a greenhouse made of plastic pipes

The project must indicate:

• dimensions and shape of the product;
• methods of fixing elements;
• quantity necessary materials and fastening parts.

After drawing up the drawing, you can proceed to the selection of materials.

You will need to buy large-section plastic pipes from which the frame is made. In addition to the main frame parts, smaller diameter tubes will be needed. The elements will connect the main arcs with each other. This is necessary to give rigidity to the structure.

Plastic tubes can be easily cut, bent, glued and welded. In greenhouse production, polymer elements are often fastened with self-tapping screws, since liquid will not flow through the parts. The manufacturability of plastic makes it possible to implement projects of almost any complexity: from a greenhouse or a small arched greenhouse to a huge all-season product with a gable roof. You just need to first decide on the design and buy necessary equipment and materials.

The following pipes are suitable for the manufacture of the structure:

All types of plastic pipes are sold with fittings, including:

• cross and tee splitters;
• swivel connectors;
• adapters for joining tubes of various sizes.

The use of fittings will speed up the process of construction work several times, but at the same time will increase financial costs.

Fittings for plastic pipes

It all depends on the capabilities and preferences of the owner. He must choose whether to use fittings or not.

To fix the frame, you will need metal rods 1.2 m long. Their diameter should be such that the rod fits freely into the tube.

The fencing edges are made from edged boards. Recommended cross-section is 150 mm. The number of parts and length will depend on the dimensions of the greenhouse.

The transverse parts of the frame are fixed using plastic tees, which are used for plumbing. Another option is to use steel wire.

At the end, the structure will need to be covered with a reinforced polyethylene or polycarbonate film.

There is one more nuance that is important to consider before the start of construction work. A greenhouse made of plastic pipes can be stationary or portable. In the first case, the parts will need to be welded or glued; in the second, the elements are fastened with screws.

Greenhouse project made from plastic pipes

The choice must be made based on needs.

Calculation of the required amount of material

To calculate materials, you will need to know exactly the dimensions of the structure. It is also important to determine the distance between the arches. If in winter period The covering of the building is planned to be dismantled, then the arches can be located in increments of 0.9–1 m.

Arch installation step

For a stationary structure, the step should be reduced to 0.6–0.7 m. This will protect the product from damage after heavy snowfalls.

It is important to consider the material for the construction of screeds, end walls, doors and windows. The total length of the longitudinal ties is calculated by multiplying the length of the greenhouse by the number of ties. Most often, at least 5 pieces are installed: two bottom, two side and one ridge. To strengthen the structure, it is recommended to install additional side ties.

Tubes will be needed for the end walls total length 17–20 m. For one door you will need at least 5 m of pipe, for a window - 2.2–2.5 m. For convenience, you can make a detailed sketch, which will indicate all the dimensions and the number of parts for fixing. An example can be seen in the image:

Diagram of a greenhouse made of pipes indicating the location of parts

As an example, we will consider a greenhouse of the following dimensions:

• length - 4 m;
• width - 2.4 m;
• height - 2 m;
• arc length - 3.8 m;
• the pitch of the arches is 0.67 m.

For the frame you will need pipes 6 m long and 25 mm in diameter. Such parts can ensure the reliability and rigidity of the structure. 25 mm fittings are used to fasten the tubes. You will also need glue.

List of materials that will be needed to build a greenhouse from plastic pipes:

• reinforcing bars;
• crosspiece for 25 mm tube;
• slats 50x100 mm;
• plastic pipes 25 mm;
• oblique tees;
• nails;
• metal strip;
• self-tapping screws;
• adhesive mixture;
• tees for pipes 25 mm.

For a greenhouse of these sizes with two doors and windows, materials will be needed in the following quantities:

• steel angle 90° with a diameter of 25 mm - 16 pcs.;
• plastic pipe 6 m long and 25 mm in diameter - 16 pcs.;
• wide tape or metal profile for connection (when using polycarbonate) - 1 pc.;

• self-tapping screws 24 mm - 48 pcs.;
• self-tapping screws 55 mm - 36 pcs.

Polycarbonate or film can be used as a coating material. If the second option is chosen, then approximately 8 linear meters of polyethylene are needed. with a width of 6 m.

Tools that will be needed:

• hammer;
• device for welding plastic tubes;
• hacksaw;
• building level;
• screwdriver or screwdriver;
• construction tape;
• hacksaw for metal.

• Desktop;
• ventilation system;
• heating boiler;
• racks;
• shelves;

• fluorescent light bulbs;
• thermometer with hygrometer.

After preparing the materials, you can begin site planning and construction work.

How to build a greenhouse from plastic pipes with your own hands - step-by-step guide

To eliminate the possibility of the building skewing during installation and use, the area under the greenhouse must be leveled.

Leveling the area for the greenhouse

To do this, you need to mark the location of the future structure on the ground using pegs and rope.

Marking the area using pegs

After this, the area should be checked with a building level. If there is a slope of more than 1°, then the area must be leveled.

A sand cushion 6–10 cm thick should be made under the base.

Determining the location for the structure

First of all, you need to determine the location on the site for the construction of the structure. It should be:

• in flat areas so that the frame can be easily mounted;
• have direct exposure to the sun's rays, otherwise the greenhouse will not have its main property;
• in open areas.

The main condition for the correct development of plants is light. This is especially true in winter and in early spring. If the greenhouse is located in a place with insufficient lighting, then it will be necessary to install additional lighting fixtures.

Lighting fixtures in a greenhouse

It is worth understanding that this can lead to high costs of grown vegetables. To make a greenhouse, you need to choose the most illuminated area, which is located at a great distance from trees and buildings. It is important to protect crops from excess shade.

The placement of the greenhouse relative to the cardinal points is an important factor when determining the location. The most preferable option is to locate the building from the west to the east.

Location of the greenhouse relative to the cardinal directions

Only in this case can crop lighting be ensured from morning to evening.

If it is not possible to place the greenhouse in such a place, then the frame must be installed so that the sun's rays enter through the covering at the beginning of the day. The morning hours are the coldest, and if the sun does not warm the air in the greenhouse, many plants may stop growing and lose their ovaries.

In insufficient lighting they can develop fungal diseases. This often leads to crop loss.

Another important factor affecting the effectiveness of a greenhouse is its location in relation to prevailing winds. This is of great importance in the case of using a protective structure throughout the year. In winter, the presence of cold winds can increase heating costs several times. If you plan to place the greenhouse in an open area, it is recommended to build barriers that can protect from the wind. Can be used hedge or a wooden fence mounted around the greenhouse at a distance of at least 10 m.

Hedge for protection from wind

This placement will avoid creating a shadow.

It is best to place the structure next to a private house so that there is free passage in winter during snow drifts. The path must be made of hard surface. This will protect the product from dirt during rain. The width of the track is determined based on the size of the wheelbarrow.

Making the base

A frame will be used as the basis, which will be able to hold a light frame and maintain its geometry parameters. The choice of the required base option is not associated with the design or type of construction. It depends on financial capabilities and whether the product is stationary or portable.

To make a frame, you will need to prepare the following elements:

• board 6 or 8 mm thick;
• block 6x12 or 8x12 mm;
• rigid plastic pipe for the bottom trim.

The base is made of thick boards. If financial capabilities allow, it is recommended to use timber. The elements are fastened by cutting half a tree without using fasteners. Accordingly, the frame will not contain metal elements that could rust.

The base of the bars will need to be buried in the soil. To do this, you first need to dig a pit. Only fill the trench around the perimeter so that the bottom and walls of the pit are covered. Next, the frame is installed.

Wooden greenhouse frame

A frame buried in a trench will serve as a foundation, but it is worth understanding that such a foundation is not necessary for a seasonal structure.

A frame made of tubes cannot be an independent base. It is made if there is a foundation made of wood, brick or concrete. Fixed with staples to bars or anchor bolts fixed in concrete during the curing process.

If the foundation is made, then it will not be possible to move the structure. Therefore, it makes sense to consider the process of making a plank frame as a basis. Sequencing:

1. First of all, you need to prepare a site for making a greenhouse. A layer of turf should be removed from the area so that the area is longer and wider than the structure being erected by approximately 1 m. This will allow for an indentation of 0.5 m on each side.
2. The surface must be measured with a building level. If necessary, the site must be leveled. A difference of 5 cm is allowed over a period of 2 m.
3. A frame should be assembled from four boards. You need to decide on the sizes in advance. The structure is fixed with several self-tapping screws or nails. Length fastening element determined taking into account the thickness of the attached part: it should be 2.5 times the thickness of the rail.
4. The frame must be measured diagonally in both directions with a tape measure. If the values ​​coincide, then the base is smooth. If not, the flaws should be eliminated.
5. The frame is installed and fixed by driving in reinforcing bars with inside corner. The length of the rod is 75–80 cm. The sections are driven flush with the frame.

Visually, the process of constructing the frame can be seen in the image:

Construction of a greenhouse base

The base will be in contact with wet soil. Therefore, the material for production must be thoroughly dried. Before assembly, the parts must be coated with hot bitumen and an antiseptic.

Manufacturing of frame structures

The first step is to do the following:

1. Along the long walls on both sides of the frame, you need to hammer in the rods with a sledgehammer so that no more than 40 cm remains above the base.
2. A piece of plastic tube is placed on the fittings.

To make internal arcs, you need to connect 2 pieces of tube 3000 mm each by welding so that the cross is located in the center.

Installation of frame arches

For external parts, the tubes in the center should be connected not with a cross, but with tees.

The frame is assembled as follows:

At this stage, openings for installing windows and doors are prepared. Structures are needed for ventilation.

The two pieces of reinforcement that were installed earlier are places for installing windows and doors. Installation sequence:

1. From the reinforcement that is driven in across the width, you need to draw a line up and make a mark on the outer arch.
2. The tools you will need are: a flat piece of wood, a marker and a building level.
3. Next you need to embed the oblique tees. You will need to measure the distance from the bottom of the reinforcing bars to the mark.
4. You need to cut a piece of plastic tube to size.
5. A tee is welded to the part so that a structure with a tee in the upper part is obtained. The bevel should mate with the tube.
6. An arc is cut at the mark. The part is under load, so work should be done carefully.
7. The tee is welded into the prepared space. It is recommended to carry out the work with an assistant.

After this, a door is made from tubes. The construction process can be seen in the diagram:

Making windows from pipes

Windows must be without special effort inserted into prepared frames.

As canopies, you can use pieces of plastic tube, but with a larger diameter. The 25mm tube should fit into the canopy easily.

How to cover a greenhouse with polyethylene or polycarbonate?

The next step is covering the greenhouse:

Covering the greenhouse with plastic film

The process is not complicated. To do this, attach the film to a wooden frame using nails and strips. The windows will also need to be covered with polyethylene and installed in their places. The following steps should be followed:

1. The supply must be distributed evenly. At the ends there should be pieces of plastic film identical in size.
2. The covering should be nailed through the boards to the frame.
3. First of all, you need to nail the film along the long wall.
4. You need to start from the middle of the surface, heading towards the corners.
5. When the covering is stretched, according to this scheme it needs to be nailed to the second wall of the frame.
6. In the end parts, the film is folded and then nailed.

In the covering that is fixed to the frame, you need to cut holes for doors and windows so that there is an overlap at the extreme parts of the holes for attaching the plastic film to the slats.

Greenhouse doors made of pipes

This method allows you to quickly make a budget greenhouse from plastic tubes. The principle of its structure is taken as the basis for many variations. The end parts can be made from plywood sheets, the dimensions of the door, the location and size of the windows can be changed, stiffeners can be mounted diagonally in the end parts, etc.

Fastening plastic film with a stapler

The reinforced film can be fixed using tube clamps. In the lower part it must be dug in with soil and strengthened by laying stones or slats on top.

If you plan to cover the greenhouse with polycarbonate, you will need to perform the following steps:

1. Wooden slats need to be placed on the frame between the ribs.
2. A solid surface is prepared. The ribs should be recessed inward.
3. Holes are drilled into which fasteners will be installed.
4. Polycarbonate is fixed with self-tapping screws. Be sure to install thermal washers.

Fastening polycarbonate with self-tapping screws and thermal washers

The diameter of the recesses in the polycarbonate should exceed the diameter of the screws by several mm. The gap is necessary to compensate for the expansion of the material due to atmospheric influences.

Products made from pipes are popular among summer residents. Many fans of year-round cultivation of vegetables are engaged in their production. Each owner has his own secret, which facilitates the construction process and reduces the cost of construction.

Some useful tips:

If you take these tips into account, you can make a high-quality greenhouse with your own hands.

Video: building a greenhouse

Any frame made of plastic tubes can be covered with plastic film or polycarbonate. The only material that cannot be used to cover a greenhouse of this type is glass.

You can make a greenhouse with your own hands that will delight you with fresh cucumbers, peppers, tomatoes, strawberries and herbs all year round. In order for the design to be of high quality, it is important to follow the instructions.

To make greenhouses on your site with your own with my own hands Various materials are used, ranging from wood to metal. The craftsmen also paid attention to such material as PVC.

Do-it-yourself greenhouses made from PVC pipes can be found quite often. This is due primarily to the relative cheapness of the material, good workability, lightness and sufficient elasticity.

A greenhouse made from PVC pipes can be assembled with your own hands quite quickly, with a minimal set of tools, and both polyethylene film and polycarbonate sheets are used for covering.

Let’s make a reservation right away: a greenhouse made of PVC pipes usually has small size and is not intended for all-season use, it is rather a greenhouse for growing early seedlings.

But nevertheless, such a greenhouse has all the elements of a real greenhouse, these are:

• Frame;

Greenhouse made of pipes - the material dictates the shape

A do-it-yourself greenhouse from PVC pipes can be made in one weekend at minimal cost.
Let's build such a greenhouse today and consider various options for its construction, both in terms of fastening the frame and installing the covering. Before we begin, we must immediately stipulate one condition: a greenhouse made of PVC pipes can only have an arched shape. Why?

Let's look at an example.

• Take a piece of PVC pipe, which is usually used for cold and hot water, measuring approximately 1000 mm;
• Let's lay the pipe on two supports so that the ends of the pipe lie on the supports and the middle is free;
• Lightly press down on the center of the pipe. What's happening? That's right, it sags.

If we need a PVC greenhouse with straight walls, in this case we will have to install additional stiffeners and stops, and this is undesirable; a greenhouse made of PVC profiles is better suited for this, but this is a completely different question.

• Now bend the pipe slightly so that a kind of arc is formed;
• If you fix the pipe in this position and press on it in the central part, you will see that the pipe has become much more elastic;
• The usual arch system operates. We think there are no more questions. Let's get started.

Greenhouse in one weekend - material, PVC pipe

Sometimes it’s possible without a foundation

Before we begin construction, we must resolve the issue of the foundation. Since the greenhouse we are setting up will not be used all year round, and our main task will be fast construction shelters for plants, we will completely abandon the construction of the foundation.

No, of course, we will need a foundation for the greenhouse, but it will not be quite a foundation. As for the sizes. If we use polycarbonate as a covering, then the size of the greenhouse will directly depend on the size of the polycarbonate sheet bent into an arc.

Our information - standard size polycarbonate sheet 2100 by 6000 mm.

Size selection

If polyethylene film is used as a covering, the dimensions can be arbitrary. Let's build a greenhouse the size 3820Х6300 mm.

Why did we choose this size?

• It is important to understand that when bending a PVC pipe, we will get the correct arc;
• Having a width of 3821 mm, we get half a circle with a radius of 1910 mm;
• In other words, this is half our width and the full height of the resulting greenhouse;
• If we decrease the width, the height will decrease accordingly.

As for the length, the pitch of our frame will be 900 mm.

• Respectively, if there are 8 sections we will have 7 spans;
• The calculation is simple: 7*900 = 6300 .

You can take a different size, the main thing is to understand the principle.

Materials for production

We will need:

• PVC pipe 25 mm
• Crosspiece for pipe 25 mm
• Tees for pipe 25 mm
• Skew tees
• Self-tapping screws
• Metal strip
• Rebar or steel rod
• Board 50X100 mm
• Self-tapping screws, nails

Main tool

From the tool we need:

• Hacksaw
• Hammer
• Screwdriver or screwdriver for self-tapping screws
• Metal hacksaw or cutting machine
• Plastic pipe welding machine
• Construction tape
• Building level

The first stage is the construction of the base

Everything is ready, let's get to work.

• It is necessary to assemble the frame of our future greenhouse from the board;
• Before installation, the wood must be impregnated with a special composition against dampness and mold;
• The frame is installed on a leveled area of ​​our future greenhouse;
• Now it is necessary that the diagonal of our frame be correctly observed.

• To do this, we cut 4 pieces of reinforcement 500 mm long and drive them into the corners of the frame from the inside. Before driving each segment, carefully measure the diagonal.

We arrange the fastening of the frame arches

The frame is ready and secured.

• We cut another 14 pieces of reinforcement, 65 - 70 mm long.
• On our frame it is necessary to make markings with a marker on the inside of its longest part, in other words along the length.
• The first mark is made at the very edge and then all the rest at intervals of 900 mm.
• According to the marks made, from the outside of the frame, we drive pieces of reinforcement into the ground so that 300 mm remains sticking out on the surface. The reinforcement is driven flush against the frame.
• Now we make markings on the frame along the width.
• To do this, divide the width in half and, stepping back 400 mm in both directions, make marks.

Here, too, you need to hammer in the reinforcement from the outside in the same way as we did in the first case.

PVC pipe - making arcs

The first stage of work has been completed. Let's move on to making the arcs themselves.

• They are made as follows: two sections of pipe 3000 mm each are welded together so that they have a cross in the middle.

This is what concerns the internal arcs of the frame.

• External elements are made slightly differently. The pipes in the center are connected not by crosses, but by straight tees.
• The first part is ready. Arcs can be installed.

• They are inserted into the reinforcement lengthwise on one side, bent and inserted on the other.
• Thus, above our wooden frame we got a frame for our future greenhouse made of PVC pipes with our own hands.

Stiffening rib - installation

Now you need to install the central stiffener.

• To do this, cut pieces of PVC pipe of size 850 mm and are welded between the central tees and crosspieces. This strengthens our frame.
• Next, it must be additionally secured to wooden frame.
• Made from metal strip clamps in the form of the letter Ω.

• Using self-tapping screws, we attach the PVC pipe frame to wooden base.

Base for door and window

The main work on the frame is completed. You need to think about the future door and window for ventilation.

Do you remember that we installed two pieces of reinforcement at our width? These are exactly the places where we will install the window and door.

• From the reinforcement driven in width, we draw a line straight up and make a mark on the outer arc of the PVC pipe.
• This can be done using a flat wooden slats, marker and level.

We have two marks on the same vertical line with the reinforcement. What are we going to do with them?

Let's insert skew tees here. You can do this as follows.

• Let's measure the distance from the bottom of the reinforcement to the mark.
• According to the obtained size, cut a piece of PVC pipe.
• We weld a tee to it so that we get an element with a tee at the top. The bevel connects to the pipe.
• Now let's cut the arc at the mark.
• This must be done with caution, the arc is under load.
• Next, we simply weld the tee into the resulting space. Of course, you can’t do this without an assistant.

Doors, windows, covering

The frame is ready.

As you can see, a DIY greenhouse made from PVC pipes is not anything complicated. All work can be completed in one day.

If you are planning, you can do this by simply nailing it to a wooden frame using nails and battens.

• The door and window can also be made from sections of PVC pipe.
• Next, they are also covered with plastic film and installed in place.

• You can also use sections of PVC pipe as canopies, but with a larger diameter. 25 the pipe should fit into it freely.

Polycarbonate coating - device diagram

If your greenhouse made from PVC pipes with your own hands will have a polycarbonate lining, then in this case you need to proceed as follows.

• Wooden blocks are placed between the ribs on the wooden frame.
• Thus, you have a continuous, flat surface with ribs recessed inside.
• Polycarbonate is fastened with self-tapping screws with the obligatory installation of thermal washers.

Our advice is that the diameter of the hole in polycarbonate should be 2 - 3 mm larger than the diameter of the screws. This gap will play the role of a compensator when polycarbonate expands due to climatic influences.

Concrete - extending the life of the greenhouse

A PVC greenhouse constructed in this way is not a long-term structure. It's all about the wooden frame of the foundation. But its service life can be significantly extended if the foundation is made of concrete.

This will not affect the structure itself at all, the manufacturing process will not change with a small exception, all the reinforcement is not driven into the ground, but is walled up in concrete.

The foundation turns out to be strong, and the absence wooden elements significantly extends the service life of such a greenhouse.

Your dimensions - how to do the calculations

Small addition.

Readers noticed that we suggested our own dimensions when making this greenhouse. But you can choose a completely different size.

Someone may wonder how, in this case, to accurately calculate the dimensions of the length of the pipe for making the frame.

As you understand, our frame element consists of two pipes and forms half a circle.

The width of the greenhouse is the diameter of this circle. If we know the diameter, we also know the radius. This data allows us to calculate the circumference.

The formula in this case looks like this:

• L = 2πR = πD
• L – circumference
• R-radius
• D-diameter

Let's imagine that you needed a greenhouse with a height of 2000 mm. This means that with the correct arc its width will be 4000mm.

In this case, the diameter of the circle will be 4000 mm and the radius 2000 mm.

Usually π (pi) is calculated as 3.1416. But for engineering calculations this is a very rough derivative. In order not to bother with large numbers, you can round it to 3.14. This will do too.

• L = 2*3.1416*2000=12566 or L=3.1416*4000=12566

This is the length of our circumference. But we only need half.

• 12566/2=6283 this is the length of our arc.
• The arc consists of two pipes and a cross. This means that the result must be divided again.
• 6283/2=3141 mm. We have received the size of the pipe we need.

Here we just wanted to show you that the calculation is not a lot of work and simply listed all the actions.

But in fact, everything can be done much simpler. Understanding that an imaginary circle consists of 4 parts, we simply need to immediately divide the length of the circle by 4.

• L = 2*3.1416*2000=12566 or L=3.1416*4000=12566
• 12566/4=3141 it's simple.

Profile – you can do it this way

Sometimes greenhouses are made from PVC profiles. In this case, the greenhouse can have various forms, it all depends on the desires and needs of the customer.

The PVC profile greenhouse has a very durable structure. Glass is usually used as a coating, but there are exceptions.

The PVC profile for greenhouses is exactly the same as for windows (see). Therefore, the use of glass in this design is entirely justified. Such greenhouses can be used both for a short period and all seasons.

The main advantage of greenhouses made of PVC profiles is their tightness and ability to retain heat well.

PVC profile for greenhouses, together with the use cellular polycarbonate give truly amazing results.

But there is one important thing in these greenhouses.

The construction of such greenhouses at home is problematic, and industrially produced greenhouses have a high price. Therefore, for ordinary summer residents they represent a kind of luxury element in the garden.

But everything changes over time, and certain materials become more accessible over the years. Let us hope for the best.

Option for the lazy and impatient

Materials

Let’s immediately take the bull by the collar and determine the required quantity and name of building materials and consumables that we (you) will need. This:

• Boards and wooden blocks for the foundation. Since such a lightweight structure does not require a foundation. The thickness of the boards is flexible, from 20 to 40 mm, but this is for a large scale. Bars – from 25x25 mm.
• The pipe is plastic, PVC, white or any other. Initially, let's focus on the specific dimensions of the future greenhouse, and we will prepare a 13 mm pipe 6 meters long in quantity 19 pieces.
• Steel fittings or steel rods with a diameter so that they fit tightly inside the pipes. Enough 10 pieces 80-100 cm long.
• Greenhouse film, thick, choose any one at the market or in a store, preferably something stronger (see). Standard width, 24 linear meters.
• Consumables: plastic or aluminum clamps, small wooden boards (50 pieces), door hinges and handles, wood screws, any small nails.

Important! The wood must be good, all elements must be treated with an antiseptic or impregnated with at least drying oil. You can do both, and also paint.

Addition: a greenhouse can be built from metal-plastic pipes, the device process is similar, choose the material yourself. Only if it doesn't cost more. It definitely won't be any stronger.

Process

Determine the location, but for now it’s better to clear it of the fertile layer by removing a few centimeters. Because during construction, nails and screws will certainly be dropped, shavings will fall, other construction debris and foreign bodies that are completely unnecessary for tomatoes will get into the soil.

And after installation, it will be possible to fill the beds inside the greenhouse with soil. At the same time, enrich it with oxygen while you dig, loosen and move it from place to place. Especially experienced gardeners They will never forget to immediately add fertilizer (see).

So, the installation of a greenhouse made of plastic pipes with your own hands begins:

• We take wooden blocks and make the simplest semblance of a foundation out of them, that is, we knock together a frame that we lay on the ground. To determine correct assembly, you need to measure the diagonals. If they are equal, then your frame is rectangular and not diamond-shaped. This finished frame can be very easily fixed if you drive reinforcement into the corners from the inside;
• How to install arches? Cut the reinforcement: each individual twig into 4 equal parts. As a result, you will have 36 pieces of reinforcement. We drive 40 cm from these pieces into the ground, let the rest remain sticking out. We hammer along the long side, approximately at a distance of 60-65 cm between adjacent ones. And we put pipes on these branches of reinforcement sticking out of the ground, so we get parallel arches along the entire length of the structure. This will be the main frame of the greenhouse made of plastic pipes;

• At each base of these arches we fasten PVC pipes to a wooden foundation frame. It can be simple clamps, which will tightly fix the end of the tube;
• Assemble the end structures according to the same principle, taking into account the rigidity that should still be present. The ends of the tubes are also placed on reinforcement driven into the ground, and then attached to a wooden frame from below;

• Check the size of the doorway while assembling it on the ground. It’s very easy to make a door together with a frame from bars; you don’t even need to cut anything at angles. Just make two rectangles, one inside the other. On the inner door (actually, the door) also nail a slanting strip to maintain rigidity. Then install the structure at the end of the greenhouse and secure it in any convenient way. We have hung the hinges, we will nail the handle after we stretch the film;

• Let's unwind it and carefully begin to pull it onto the structure. It is better to do this when the sun is outside and the weather is warmer than cooler. But you also don’t need to work in the heat, otherwise the film will then be stretched too tightly due to thermal expansion (more precisely, contraction), which can lead to its ruptures, especially in places of contact with pipes and in kinks. You can also fasten the film at your discretion: with slats, boards, or simply place a certain number of bricks on the free ends so that gusts of wind do not blow it to the northwest.

That's it, the greenhouse made of plastic pipes was installed in half a day. Don't forget to screw the door handle.

Polymers are persistently displacing wood, glass and metal from industry and everyday life. They didn't pass by summer cottages and country farms. Lightweight, durable plastics are not corroded by mold, evaporation, caustic chemicals, or moisture do not spoil them. Polymer greenhouse structures last longer than all types of outdated predecessors and withstand atmospheric adversity. The only disappointments are the price of greenhouse structures from manufacturers and the sizes, which do not always coincide with the needs of gardeners. There is no need to be discouraged: you can build a greenhouse yourself from plastic pipes without any problems or financial costs. However, with patience and knowledge of the nuances independent master It doesn't hurt to stock up.

Plastic pipes are easy to cut, bend, glue, and weld. In greenhouse construction, polymer parts can even be connected with self-tapping screws, because water does not have to flow through their strong “veins”. The manufacturability of the material makes it possible to implement literally any complex projects: from a greenhouse or arched mini-greenhouse to an impressive all-season building with a gable roof or a fantasy polyhedron. You just need to decide in advance on the priority own view design and purchase suitable material. Because the family of polymer pipes suitable for DIY construction includes:

• rigid polyvinyl chloride representatives (PVC), not characterized by elasticity. They are used for the construction of gable and single-slope, “green houses”, i.e. designs with straight lines and edges, which were different from the wooden “ancestors”;
• flexible polypropylene and polyvinyl chloride counterparts (PP, PVC), from which they prefer to build arched structures or erect rounded roofs over a rigid frame made of hard plastic elements, metal profiles or wooden slats.

All types of polymer pipes are produced with fittings: cross and tee splitters, rotary connectors, adapters for joining pipes of different diameters. The use of fittings will significantly “revive” the pace of construction, but will increase the budget. We will attribute this fact to the personal preferences of the future owner and allow him to choose whether to use connectors or not.

There is one more criterion that needs to be determined “on the shore”. A self-created greenhouse made of plastic pipes can be stationary or collapsible. In the first case, the structural parts of the green house are welded or glued together forever, in the second they are screwed on with screws.

Regardless of the chosen project, the construction process includes a number of characteristic stages:

• construction of a base that replaces the foundation, because there is no reason to pour a concrete strip or support pillars under a light plastic building;
• assembly of a frame from flexible or rigid polymer pipes;
• fastening a light-conducting coating, which is best suited for plastic greenhouses using reinforced polyethylene film. Polycarbonate is used less frequently. But glass is strictly prohibited;
• production of end parts with vents and doors;
• hanging transoms, sashes, doors, locks.

Let's look at the general rules and two common methods of building a house for tomatoes and cucumbers that are quite accessible to a novice performer.

Base for polymer frame

Before delving into the question of how you can make a reliable structure from plastic pipes yourself, you need to understand the basis. Those. with a frame that will hold the super-light frame and maintain its geometric parameters. The choice of the best base option is not related to the project and type of structure. Rather, it depends on the degree of capital of the building and on the funds available to the owner.

To make the base frame you can use:

• board, thickness 6, even better 8mm;
• timber with sides 6×12, 8×12 or more;
• a rigid plastic pipe that can only perform the function of the bottom trim.

Most often, the base for a light plastic frame is made from a thick board, because its load-bearing capacity is quite sufficient. For those who do not experience financial constraints or are planning to install a complete greenhouse, timber is suitable. It is connected by cutting half a tree without using hardware. This means that there will be no rusting metal parts in the wooden frame.

The timber base can be buried in the ground, for which you first need to dig a trench. First, roofing felt is laid around the perimeter of the trench, covering the bottom and walls of the dug trench, and then a wooden frame is installed.

A frame made of a polymer pipe cannot be considered an independent basis. It is constructed if there is a wooden, brick or concrete foundation. They are fastened either with staples to the beam or to anchor bolts fixed in the concrete during its hardening or in brickwork during the period of its establishment.

All of the options listed are compatible with any plastic greenhouse project. However, you need to take into account that if you have a foundation, you will have to forget about periodically changing the location of the green house. Therefore, we will consider the procedure for manufacturing the most popular and simplest type of base - a plank frame:

• We are preparing the site for construction. We remove a layer of turf from the area so that the area freed from it is longer and wider than the future structure by about a meter, so that it is retreated by half a meter around each side.
• We measure the surface with a construction spirit level. If necessary, level the site. The permissible height difference is 5 cm, distributed over 2 m.
• We assemble a wooden frame from four thick boards with pre-calculated individual dimensions. We fasten with two, preferably three, galvanized screws or nails. The length of the hardware is determined based on the thickness of the attached element: it should be at least 2.5 times the thickness of the board.
• Using a tape measure, measure the frame diagonally in two directions. If the diagonal indicators match exactly, the base came out perfectly. If not, we look for and eliminate flaws.
• We install the assembled frame in the intended place and strengthen it by driving four pieces of reinforcement into the inside of the corner. The length of the rod driven into the corner is 70-80 cm. The reinforcement sections need to be driven almost flush with the frame.

The process of making a board base will be demonstrated in the photo:

The wooden frame will be in contact with wet soil and will have to withstand the onslaught of precipitation. Therefore, the board or timber for the base should be well dried and treated with hot bitumen before assembly. It is also advisable to soak it in kerosene-butum antiseptic.

Do-it-yourself elementary greenhouse made of flexible pipes

To build a simple arched structure we will need:

• pieces of reinforcing bar 75 cm each. It is advisable to stock up on reinforcement Ø 10-12mm. It is better to choose A3, because smooth rods without embossed ribs are simpler and easier to drive into the ground. We calculate the number of pieces in advance. They are driven into the ground along the long sides at approximately 60 cm ± 5 – 7 cm. In order not to bother with dividing the reinforcing bars into parts, we order cutting to size from the seller;
• white flexible PVC pipe with walls no thinner than 3 mm. We purchase it based on the number of pieces of reinforcement intended for installation on one side. How many pieces there should be so many pieces 6 m long. Plus one more piece for the screed if the length of the greenhouse is up to 6 m. The classic school formula will help the buyer of material in coils to calculate more accurately, according to which they calculate the circumference (two-pi-er) . The result obtained should be divided into two and slightly adjusted if you are planning an arch of a slightly elongated shape, such as a half oval;
• plastic clamps for fastening the arches into a single structure with a tie. The number of clamps is equal to the number of sections of polymer pipe;
• metal mounting brackets; it is more convenient to take aluminum fasteners for drywall. They are needed to fix the arches to the wooden base. We purchase 2 per piece of pipe;
• polyethylene film 6 m wide. Excellent if you have enough money for reinforced material. We calculate the footage by summing the length and two heights. We add ≈ 1.0 m for reserve for unforeseen changes in dimensions in fact.

You will also need thin wooden planks for attaching the film about 50 cm long, timber for constructing the door frame and frame for the windows, nails, locks, screws, hinges for hanging the door and opening sashes. The craftsman will determine these costs directly on site.

We prepared the material, got inspired and started building an economical greenhouse from plastic pipes as follows:

• Along the long walls on both sides of the frame, we hammer in pieces of reinforcement with a sledgehammer so that no more than 40 cm remains above the surface.
• We put a piece of PVC pipe on the reinforcement bars located on opposite sides.
• We fasten the resulting arches to the wooden frame using metal staples.
• We arrange the ends of the structure by knocking together a doorway from a block, which will also act as a box. We reinforce the ends with additional wooden parts to ensure rigidity.
• We install the top tie of the arched structure. It should pass through all the highest points of the arches. We attach the screed to the arches with polymer clamps.
• Cover the structure with film, evenly distributing the stock. At both ends there should be pieces of polyethylene equal in size. We nail the covering through the planks to the frame. First, we nail the film along one long wall. We start from the middle of the wall, heading towards the corners. Then, having moderately stretched the covering, we nail it to the second wall of the frame using the same pattern.
• At the ends we decorate the film with peculiar folds and nail it.
• We will make the door and windows in advance. They must be covered with film and freely inserted/exposed into the frames intended for them.
• We cut holes for the door and window in the base of the covering, so that there is an overlap along the edges of the cut hole to fix the polyethylene to the beam.
• We screw on the hinges for the windows and doors, hang what should hang on the hinges, and install locks.

This the simplest way will help you quickly build an inexpensive greenhouse from PVC pipes. The principle of its construction is taken as the basis for numerous variations. The ends can be made of plywood, the dimensions of the door, the location and dimensions of the vents can be changed, stiffeners can be installed diagonally at the ends, etc. It is not necessary to nail the polyethylene with planks; instead, it is wiser to use furniture stapler.

There are countless options. We invite you to familiarize yourself with useful video on the topic “how to competently build a greenhouse from plastic pipes”:

Technological path “from the reverse”

Surely, after familiarizing yourself with the simplest principle of constructing a greenhouse, doubts remained about the logical sequence of actions. Everything was good and simple until we got to arranging the ends. Then it is necessary to try on the already installed frame more than once to determine the appropriate position of the windows and doors. It is not easier to start by making the ends, as in the method described below:

• To the board, the length of which is 10-12 cm greater than the width of the planned greenhouse, we temporarily screw a 6-meter section of pipe with self-tapping screws to form the outline of the structure. We screw it in lightly at first so that the pipe can be slightly rotated to adjust the configuration. As soon as we reach perfect shape end, screw it in with some force, without being too zealous, so as not to damage the polymer part;
• We will make a frame for the door frame from a 2 cm thick board, selecting the optimal position of its parts at our discretion. To strengthen the frame, we will install oblique struts;
• glue the intersections of the door lintel and jambs, then screw two screws into the crosshairs;
• outline the outline of the arch on the wooden frame parts to saw off the excess;
• drill a small diameter hole in the center of the crosshair. We pass a plastic clamp through it to connect the frame and the plastic arch.
• We will strengthen the connections with plywood elements.

We do the same with the second end; we check its congruence with the first during the manufacturing process. It is very convenient to adjust parts of the structure until they are installed in the planned place. The second end can be equipped, by analogy with the first, with the same opening door. However, it is better to install a window into it, for the installation of which another smaller frame will need to be placed inside the existing frame.

An interesting point is the sheathing of the end with polyethylene, performed according to the following algorithm:

• We spread polyethylene on the ground, on which we place the previously made end face down;
• We fasten the covering with a stapler to the trim board from above so that the metal fastening brackets are on the inside of the future structure;
• wrap the free edge of the polyethylene over the end;
• We attach it to the slanting slats that strengthen the frame and cut off the excess;
• cut a hole in the middle of the polyethylene-lined end, departing 10-15 cm from the existing outline of the opening;
• We cut a hole in the corners, not reaching the frame 0.8-1.0 cm.

The final step is to fold in our plastic allowance and staple what we have folded.

The frame assembly scheme will be slightly different from the previous method. And although the lower harness is produced by analogy, that is, the base in its normal understanding is absent. The first step is to hammer in the reinforcing pins, then install the ends. Then connect installed elements into a single structure with one or more ties. But there is less fuss with arranging the openings and it is easier to attach the light-conducting coating.

The polyethylene sheet is simply fixed on both sides at the base of the frame. A strip is simply placed on top of it, which is screwed to the plastic arches with self-tapping screws. Around the ends, the polyethylene must either be assembled as a frill, or attached to the end arch using clamps cut from a slightly larger pipe.

Construction of a frame with plastic walls

It often happens that standard height the arc of a homemade greenhouse is inconvenient for tall family members. An ingenious invention of folk craftsmen will help to cope with the problem, according to which flexible PP and rigid pipes are used in the construction PVC varieties. In order to increase the height, sections of rigid polymer pipe are first placed on the reinforcement pins driven into the base, to which arches are attached using plastic crosses and tees. There are no other fundamental differences, so instead of a description we will attach a photo selection:

Rules for building a greenhouse from rigid pipes

For adherents of traditional forms, polymer pipes also offer a lot of technological opportunities. The photo shows an example of the construction of a single-slope structure; gable options are constructed by analogy.

Any frame made of practical plastic pipes can be covered with polycarbonate. To fix it, you must use roofing screws with thermal washers. The list of priorities of a polymer material does not include only the possibility of glazing. But based on the above examples, without a doubt, a lot of your own ideas for building a green house will appear.

Almost every summer cottage the owners set up a greenhouse or greenhouse, and most prefer to do it with their own hands. Previously, various natural materials were used - wood, metal, glass, but today plastic is increasingly being introduced into the yards of private owners. A greenhouse made of plastic pipes is modern, simple, convenient, durable and cheap. Moreover, it is assembled as if from a Lego constructor: with your own hands and practically without tools.

A greenhouse made of plastic pipes is becoming increasingly popular because it has a number of undeniable advantages. It’s easy to make, the assembly itself will only take a few hours, you don’t need to be a professional, just decide on the dimensions, make a drawing, buy and bring the necessary materials. Since plastic pipes are light in weight, transporting them, loading and unloading them, and assembling a greenhouse or greenhouse does not require much physical strength. Therefore, you do not need to involve many people to work.

Any structures made of PVC (polyvinyl chloride) or HDPE (polyethylene) pipes low pressure) are easy to assemble and dismantle, which can be very convenient in the country. Greenhouses for seasonal use are often made, covered with plastic film: the owners use them all year round, after use they remove the film, disassemble the frame, put it away for the winter, and put it back together in the spring. By assembling the structure with his own hands, the summer resident wants not only to save money, but also to implement own desires, plastic elements are best suited for this.

Perhaps the most important advantage of plastic pipes compared to other materials used is the absence of their interaction with water, earth, air - PVC and HDPE do not rust, do not mold, do not rot, and do not emit any harmful substances neither into the air nor into the ground. This explains the durability of the material - an important quality in itself. And environmental friendliness in agriculture, of course, welcome.

What types of greenhouses are there from PVC pipes?

Greenhouses are most often made:

• arched;
• gable;
• single-pitched.

For arched greenhouses made from PVC pipes with your own hands, knock down a box from boards or wooden beams. The pipes are placed on metal, or less often wooden, pins (pegs), which are securely fixed in the ground; there should be a 30-40 cm pin on top that fits freely into the pipe . If such a greenhouse (greenhouse) is covered with plastic film, then the ends are usually covered with plywood, wood board or plastic, in which doors and vents are made for ventilation. If the arched structure is covered with polycarbonate, then the end sides are made from it.

Single-slope and gable greenhouses are covered with both film and polycarbonate. Such a heavy, fragile and expensive material as glass is being used less and less for greenhouses and greenhouses in our summer cottages, which is not surprising.
Pipe structures are usually installed on a foundation or rigid base to add rigidity and stability due to the lightness of the material.

How to build a greenhouse from flexible pipes

Arched greenhouses and greenhouses are usually made with your own hands from flexible pipes with a diameter of at least 20 mm. In order to build such a greenhouse, you need to take:

• metal pins with a diameter of 10-12 mm and a length of 50-75 cm;
• plastic pipe with walls 3 mm thick;
• plastic clamps for connection;
• aluminum fasteners to attach the arches to the wooden frame;
• polyethylene film for covering;
• boards that will help secure the film.

The amount of materials must be accurately calculated according to the drawing, which will inevitably have to be made if we want to assemble the structure with our own hands. You will also have to purchase wooden beams for door frames, vents, hinges for hanging opening sashes, nails, locks, and screws. In the most convenient place for the greenhouse, you need to mark its position, use a sledgehammer to drive metal rods into the ground along the long walls, leaving 30-40 cm outside.

Now you need to put the pipe on opposite pins and attach it to the wooden frame with metal brackets. All arches are made this way, and the more often they are located, the more stable the entire structure will be. If the frame is made under polycarbonate, then the step is commensurate with the size of the sheet; polycarbonate will make the greenhouse (greenhouse) heavier, more stable and simply tougher. And if the covering is supposed to be made of film, then the more often the step, the more stable the greenhouse, the less the polyethylene will leak, and, therefore, the longer it will be used.

Now we need to assemble the end walls, insert doorways, vents, and additional pieces of wood to stiffen the frame. After this, the top screed of the arched structure is installed. It passes along the highest points of all arches and is attached to them with polymer clamps.

The finished frame is covered with film, placing it in such a way that pieces of the same length remain at the ends. They secure it with planks, press the film with them and nail them to a wooden frame on one long side. Moreover, you need to start from the middle, and not from the corners. After securing the film on one side, straighten it evenly and do the same on the other long side: nail the boards, starting from the middle and moving towards the corners.

At the ends, the film is folded and nailed down. Doors and windows pre-covered with film are hung. If the ends are also film, then the film under the doors and windows is cut out so that enough remains to be fixed to the beam. This is a simple scheme for constructing an inexpensive greenhouse (or greenhouse) with your own hands, using plastic pipes. Based on it, you can create something individual, more aesthetic, artsy, or suitable specifically for a specific area.

Some people do not use planks to secure polyethylene; instead, they use a furniture stapler. Others add ribs at the ends for rigidity, and many make the ends from an opaque but rigid material. That’s the beauty of building something with your own hands - you can give free rein to your imagination and choose the most acceptable one from the many options. Flexible plastic pipes in this case are the most suitable material.

Using rigid pipes

Rigid plastic pipes are usually used for the construction of lean-to, side-wall and gable greenhouses. Using fittings, you can assemble a frame without gluing, this is convenient for greenhouses used temporarily. Rigid pipes are connected with polymer tees or couplings, covered with plastic film or polycarbonate - all options are good. The only thing that cannot be done when using plastic pipes is glazing. It is not practical to use glass in a frame made of PVC or HDPE pipes.
