Tool for laying gas silicate blocks. Trowel for aerated concrete - features, advantages, manufacturing

Building a house from aerated concrete is a rather painstaking process that requires considerable effort, certain knowledge and skills in working with building materials and tools. To make the construction of a house as efficient and less tedious as possible, you need to purchase a basic tool for laying aerated concrete.

Building a house from aerated concrete blocks is considered one of the most practical and popular in our time.

The entire set can be divided into two groups:

1. Basic: trowel bucket, wall chaser, mallet, hacksaw.
2. Auxiliary: building level, spatula, square, cord.

This is a very important tool for laying gas silicate blocks, designed for convenient and quick application of a thin layer of adhesive composition and its uniform distribution over the surface. The edge of such a trowel has teeth throughout the entire working area.

The trowel-bucket greatly facilitates and speeds up work with horizontal and vertical surfaces of aerated concrete masonry.

Laying aerated concrete blocks cannot be done without a trowel bucket.

Since the work involves the use of heavy solutions, the trowel is made from a fairly thick metal sheet and undergoes a polishing and galvanizing procedure to extend its service life and add aesthetics. appearance.

The variety of shapes and sizes of the trowel is determined by the nature of the work being carried out, so the device can be trapezoidal, with a rounded nose, triangular, angular, toothed, etc.

The width of the tooth blade can also be different, but in this case It is appropriate to purchase according to the block size. This will greatly facilitate the work of the master.

Trowel ladle for can have different design, which is determined by the size of the block, its geometry and other features.

Advantages of a ladle trowel for a gas block:

• ensures uniform application of the adhesive mixture to the surface gas concrete block;
• prevents the solution from spreading, so all surfaces of the construction site remain clean;
• promotes the creation of thin-seam masonry with a thickness of 3 mm.

Flaws:

• insufficiently reliable attachment of the handle to the blade by means of spot welding;
• short service life - no more than a year.

Wall chaser for gas silicate blocks

During this time, it is necessary to make grooves in the surface of its walls, which are needed for electrical wiring, laying fittings and small pipes. It is for such purposes that a tool such as a wall chaser for aerated concrete is intended.

The wall chaser can be manual or electric.

Tool manual type has such advantages as simplicity of design, ease of operation, low noise level and insignificant amount of dust. But such a wall chaser can only cope with light cellular surfaces.

To process durable concrete or reinforced concrete surfaces, you will need an electric wall chaser. Only such a one can make furrows like in brickwork, and in a reinforced concrete wall. Externally, the design of an electric wall chaser resembles grinder, and grooves are created using discs on concrete or stone.

Since a large amount of dust is generated when working with a wall chaser, it is necessary to use personal protection. These include noise protection headphones, glasses and a respirator to prevent dust from entering your hearing, vision and breathing organs.

Planer for material

Before laying each subsequent row of gas silicate blocks, it is necessary to level the horizontal and vertical surfaces of the walls of the house. For these purposes, use a planer for aerated concrete. In addition, this is used to remove the protruding part of the concrete block.

Outwardly, it resembles a traditional construction trowel. In his wooden base cut into segments of a fine-tooth saw, which are arranged in two blocks positioned at an angle relative to each other. It is this arrangement that allows for cleaning off uneven parts of the block.

Many “craftsmen”, in order to save money, prefer to use a regular carpenter’s plane or semi-jointer instead of a branded plane. This will only complicate the work, significantly increasing the time it takes to complete it, since constant breaks will be needed to sharpen the teeth of the plane.

The purpose is to obtain blocks custom size(additional) as a result of their sawing. Only with the help of special corners included in the concrete hacksaw kit is it possible to obtain geometrically correct parts of the block.

If you need to cut a certain number of blocks, you can use an electric bandsaw.

In appearance, the design of a hacksaw for aerated concrete blocks resembles a regular hacksaw, but it is made of more durable materials, which protect the tool from deformation during operation.

Other

A mallet is a rubber hammer designed to level the surfaces of a block during installation. Since aerated concrete block is a fragile building material, using a regular hammer would be inappropriate, since its impacts will lead to destruction of the material.

The function of a metal square is to accurately mark a concrete block for sawing and obtaining additional elements. The square has a base and a ruler, on the surface of which there are inch or metric divisions. The scale can be one- or two-sided. On sale, the square can be found in granite, wood, and metal.

A spatula is an auxiliary construction tool that is used to grout joints and chips of a concrete block.

The building level is used to control the evenness of the horizontal and vertical surfaces of the masonry.

A drill with a mixer attachment is necessary for preparing a homogeneous building mixture. Can be manual or electric.

The list of tools is not too complicated and purchase it for quality work simply necessary.

Given the relatively high cost of the instruments, many have wondered whether it could be used self-made. The article provides instructions that describe in detail how to make a tool for laying concrete with your own hands.

The use of aerated concrete as building material significantly simplifies the construction of houses or other structures. Since it is easy to process, you can get by with a set of simple hand tools, some of which you can make yourself directly on the construction site. This will allow you not to waste time making a purchase and optimize costs. Moreover, it is not difficult to make a tool for laying aerated concrete with your own hands if you follow the instructions.

Homemade trowel for laying aerated concrete

Using a trowel, a solution is applied and leveled to hold the aerated concrete blocks together. It is a figured scoop, on the bucket of which there is a row of teeth. The width of this tool must correspond to the size of the blocks with which it is used. This allows not only to reduce glue consumption, but also to perform masonry more accurately and faster. Using a trowel, applying and leveling the mortar is done in one motion.
But the trowel has a weak point - it often breaks where the handle connects to the work bucket. Moreover, such a breakdown is typical for all models, regardless of the manufacturer of the tool and its cost. This is due to the fact that in the process of applying the glue to the block, a small force has to be applied, plus the solution itself has a fairly large mass. The peak of the dynamic load occurs at the junction of the bucket and the handle, as a result of which the fastening gradually loosens over time and the handle breaks off. As a rule, this happens after a month or two of intensive use of the tool.

The technology for making a trowel yourself is quite simple; all the tools necessary for this, as a rule, are always available at the construction site. First of all, you will need to make a bucket template out of paper (it should be laid out on a plane) and transfer it to a piece of sheet steel. After this, the workpiece is cut out, then, using a mallet, the ladle is bent properly on the anvil. Welding is used to fasten the seams. You can use a grinder to cut out the teeth that cover the working edge.

To ensure reliable fastening of the handle, its wooden base must be drilled through the length. A steel rod of appropriate thickness is inserted into the resulting hole. One end of the rod must be riveted so that a “hat” is formed. The back side of the bucket is drilled with a drill of the same diameter as the handle. A rod is inserted into the resulting hole so that the “cap” completely covers it. A thread should be cut on the opposite side of the rod, then a wooden base should be put on and secured with a nut. After this, the tool is ready for use.

Important! Do not forget to place a locking washer under the nut, this will significantly increase the reliability of the connection.
If you have certain skills, making a homemade trowel will take about half an hour, which is significantly less than searching for a tool required size in specialized stores, not to mention the monetary costs.

DIY planer for aerated concrete

Using a plane, the protruding parts of the aerated concrete blocks are leveled. He is wooden board, to one of the planes of which a handle is attached, on the plane opposite to it, working elements made of several segments of a carbide alloy saw are located at an angle. There are ten such elements in total (five on each edge).

Such a tool needs to be “felt”, otherwise it will be difficult to maintain one level for the entire “penetration”, since if more than necessary is removed from the block, then it will not be possible to correct the situation. The only way out is to take another block instead of the damaged one. Note that a factory-made tool does not guarantee the quality of processing; it all depends on experience. Many craftsmen prefer homemade planes, since it is easier to adapt to such a tool.

To make a plane you will need to prepare the following materials:

• a thick board (preferably “fifty”);
• handle, it can be taken from a broken tool or made from wooden block;
• glue that allows you to glue metal and wood together, you can use “Moment” or any other with similar properties;
• fragments of a fine-toothed saw blade consisting of several segments.

When all the materials are ready, you can begin assembling the tool; it is performed according to the following algorithm:

• It is necessary to make cuts along the edges of the board (five pieces on each side). They must be made at an angle of about 70° relative to the longitudinal axis;
• the saw blade or its fragments must be broken into pieces of suitable length, and then inserted into the sawn grooves, having previously applied glue to the parts to be joined;
• After the glue has dried, the plane will be ready for use.

Recommended for use with a plane special device, limiting the layer to be removed from aerated concrete blocks. To do this you will need two boards with a thickness of 20 to 30mm. They are fastened crosswise using two slats so that they form an opening equal to the thickness of the block (respectively, height or length if other sides are processed).

Do-it-yourself manual wall chaser for aerated concrete

This tool is used in cases where it is necessary to cut grooves in aerated concrete blocks (for example, to strengthen the structure, masonry is reinforced with reinforcement).

Manual wall chasers can have a curved or straight handle. Both are equipped with holders for two hands, which is very convenient, since this design allows you to evenly distribute pressure during the process of cutting through the grooves. Thanks to the presence of such a tool, the work is done with high accuracy and quite quickly. Considering that a manual wall chaser is easy to make yourself, it makes no sense to spend 300-500 rubles on its purchase.

To make it you will need a half-inch metal water pipe about one meter or more long and a small piece of sheet steel.

Now let's move on to the list of necessary tools, we will need:

• metal welding machine;
• corner Grinder, as well as a metal cutting wheel for it;
• sledgehammer (the bigger the better);
• an anvil or workbench equipped with a vice.

Almost everything necessary tools, as a rule, is available at the construction site. Now let's move on directly to the process of making a manual wall chaser. This work includes the following activities:

1. Using a grinder, the pipe is trimmed so that its length is from 70 to 80 centimeters;
2. Using a sledgehammer, bend one end of the pipe at an angle of 90°;
3. We bend a small steel plate in such a way as to obtain a u-shaped bracket, it will act as a cutter;
4. Using a grinder, we sharpen the cutter, and then weld it to the pipe (to its straight part);
5. From a piece of pipe we make a handle 12 to 15 centimeters long and weld it to the frame of the wall chaser, after which the tool can be used for work.

The aerated concrete trowel is an indispensable construction tool that allows you to correctly and quickly apply adhesive composition onto the surface of the block. The device has a special, but quite simple design, so it’s quite possible to do it yourself.

A trowel special for laying aerated concrete is used as a mortar dispenser. So hand tools Simply spread the glue evenly over a flat surface:

• hold the trowel by the handle and scoop required amount adhesive composition;
• Apply glue to the horizontal and vertical surfaces of the seams and immediately, with a simple longitudinal movement, level it over the entire area using the teeth on the tool.

When running a trowel along the masonry, the entire portion of the applied mortar passes between the teeth and is distributed over the area in a layer of the same thickness. Thanks to this, the entire working surface of the aerated concrete block is evenly covered with a thin layer of glue, which completely eliminates the occurrence of cold bridges, reducing heat loss in winter.

Features of the trowel design for aerated concrete blocks

The design of the device for applying glue to aerated concrete blocks differs from a trowel for concrete or plaster. In appearance, the tool resembles a parallelepiped-shaped ladle with a handle. On the side of the free edge there is a row of teeth that form the thickness of the adhesive seam. Their height ranges from 4 to 10 millimeters.

The width of the trowel corresponds to the width of the aerated concrete block. On sale you can find a tool with a grip from 7 to 40 centimeters. A manual device for applying glue is made from stainless or black steel. Often the structure is coated with special paint.

You can also find plastic trowels on sale. They are low in cost, but have low strength and quickly fail. Due to this, they are used for one-time laying of blocks.

Convenient use of the tool is provided by handles with a rubber or plastic holder. Its surface can be smooth or corrugated. This design of the trowel allows you to accurately apply glue to horizontal or vertical surfaces; the shape of the bucket allows you to use the glue only for its intended purpose.

Therefore, the trowel contributes to the economical consumption of the mixture holding the blocks together. In the absence of losses, glue consumption is several times lower than that of conventional bricklaying mortar.

Criteria for choosing a trowel for aerated concrete

The selection of a device for distributing the binder composition for aerated concrete is carried out according to the following parameters:

• tool width;
• teeth size;
• quality of material;
• reliability of fastening the handle to the bucket;
• presence of a comfortable handle.

The trowel bucket must exactly match the width of the aerated concrete block. This feature of the choice of tool allows you to completely cover the required surface of the block. adhesive solution. If you choose a bucket wider than the block, then it will be almost impossible to work with such a device.

The length of the teeth on the trowel determines the thickness of the glue applied. The longer the protruding edges of the tool, the larger the layer of bonding mixture obtained. Correct selection hand-held device aerated concrete ensures not only ease and convenience of the work process, but also the quality of the masonry.

Also, when choosing a trowel, you should pay attention to the quality of the material. It is most reliable to purchase devices made from stainless steel. Also carefully check the attachment of the handle to the bucket. The handle should be comfortable and not slip in your hands. Often holders are made of rubberized material.

Application benefits

Without a trowel in the form of a ladle, it is quite difficult to correctly distribute special glue over the surface of an aerated concrete block. The use of such a tool has many advantages:

• uniform distribution of the adhesive composition;
• the ability to create a bonding layer of a certain thickness;
• reduction of solution losses during application;
• ensuring speed and facilitating the work process.

The thickness of applying glue using a trowel is about 1 to 3 millimeters. The working part of the tool in the form of a bucket allows you to prevent the spreading of the fastening solution along the sides of the aerated concrete blocks. This property allows not only to avoid unnecessary expense glue, and also helps to maintain the cleanliness of the walls during masonry.

Making a trowel for aerated concrete with your own hands

When building a house from aerated concrete blocks, more than one trowel is usually used. This is due to the fact that under constant load the handle becomes loose and becomes detached from the bucket. Therefore, before starting masonry, you should purchase several spare tools in advance from a specialized store or make them yourself.

The process of making a trowel for aerated concrete is not particularly difficult:

• a template for the future bucket is initially prepared from a paper sheet;
• the cut parts are applied to the steel sheet and the measurements are marked;
• a steel shape of the workpiece is cut out according to the intended template;
• on the anvil, using a mallet, the pre-designed sides of the ladle are bent;
• side seams are connected by welding;
• on the edge work surface teeth of the required size are cut with a grinder;
• to fasten the handle along its entire length, a hole is drilled into which a rod made of iron is inserted for strength;
• in the place where the handle and bucket are fastened, a hole corresponding to the diameter of the steel rod is made;
• one end of the rod is riveted so that a “cap” is formed and secured in the opening on the bucket;
• on the other side of the rod, a corresponding thread is cut and a wooden base is put on, which is tightly secured with a nut, which is secured with a locking washer.

Sometimes if it is not possible to carry out welding work, then the trowel is made from a wide spatula with teeth. Its size must exceed the width of the aerated concrete block used. The spatula is bent on both sides using improvised means, fixing the required grip of the future tool. It is not recommended to make a fairly large bucket, since the adhesive mass is quite heavy and the handle may not withstand heavy loads.

The edges of this homemade device will be used as stops that will protect the tool from unnecessary sideways movements. The teeth of the trowel help distribute the solution along the entire length of the block. This design is not very efficient, but it still allows you to simplify the workflow a little.

Making a homemade trowel does not take much time, but significantly reduces cash costs. If you have the skills and good stuff To make a tool, you can make a device for applying glue that will last quite a long time.

The use of a trowel in the construction of houses made of aerated concrete is quite justified by its efficiency, convenience and ease of use. A specialized tool will not only save time on laying blocks, but will also significantly improve the quality and reliability of the seams.

Gas silicate differs from standard blocks in two parameters:

1. The texture of the material is quite durable, but at the same time smooth. Which ensures maximum fit.

2. The weight of each block is several times less than that of the same volume of brick, which makes the construction of structures from such material very, very simple.

Features of gas silicate blocks

There are three main types of blocks. These include structural, structural-insulating and insulating. True to its name, the structural type has a more durable structure, but does not retain heat well.

Structural insulating is used for small partitions. Combines stability and thermal insulation in equal parts. Insulating blocks can be used in residential walls.

However, it must be borne in mind that thermal insulation is achieved thanks to a large number bubbles in its composition. These same bubbles can make the material more loose.

Laying gas silicate concrete with your own hands: methods and requirements

When installing a wall made of aerated blocks, you do not have to use much force.

They are light and can be easily cut with a saw or a hacksaw. However, their disadvantage is their high hygroscopicity. Because of this, direct contact with the wall is prohibited.

Such a wall must be covered with a layer of plaster or something like that.

According to the characteristics of experts, masonry can be done both in winter and in summer. The material is not fancy.

Technical features of KBB installation

You can fasten the material either cement mortar, or special ready-made composition. Let's look at the advantages of both.

The advantages of the first option include price. Raw materials are quite cheap and always available.

However, when using of this material the seam should be from 4 to 6 mm. Thus, the material consumption is very large.

Although this allows you to even out some errors and irregularities long time after installation. But even such a wide layer does not provide thermal insulation. Moreover, cement itself allows cold to pass through, and therefore the seam is a kind of gap for it through which it will sneak into the house.

Artificial silicate cement-based adhesives are more expensive, but do not require large quantities when used.

Thanks to the thinness of the seam, the wall will let in less cold than it would if it were held together with cement mortar.

Tools and materials required for laying gas silicate concrete

For expanded clay concrete masonry and gas silicate concrete, mostly standard materials are suitable. Everything except tools for cutting blocks.

The blocks are very easy to saw. And therefore, the minimum deviation from the norm will be forever imprinted on the block.

The use of a grinder and a circular saw is unacceptable. Much would be better suited long saw.

But you also need to take care of the availability of the following materials.

1. Waterproofing. It can be a roll or a mixture.
2. Glue for gas silicate concrete.
3. The fittings are made of steel or glass composite. Distinctive feature The advantage of a composite is that it can be bent into any shape. But in this case you will have to sacrifice the strength of the wall.
4. You need two primers: adhesive and deep penetration. The adhesive primer is applied directly to the block, and the deep penetration primer is applied as a second layer.
5. Plaster can be applied in either a thin or thick layer.
6. You will need a cement solution or its substitute designed specifically for gas silicone.
7. Finishing is done randomly. Ordinary brick can also be used.

You can use Portland cement with plasticizers. In this case, it will take three whole days for maximum drying. During this time, you need to monitor the evenness of the wall.

If suddenly a wall is built with the expectation of low temperatures, it is worth using glue with frost-resistant additives.

At the same time, the glue can withstand temperatures from -25 to 35.

Stages of laying gas silicate concrete

In order to make high-quality masonry, it is necessary to make preliminary markings. The markings must be clear and even. All angles must be calculated with a level.

The surface must be smooth and clean. To do this you need to clean the surface. After this, the surface is cleaned using grinding disc. However, you can also use regular polyethylene film.

The first layer is laid in a checkerboard pattern. Then the blocks are lubricated with water and then with fastening material.

The masonry is checked with a level, after which the second row is laid. The mixture of fastening material and water is mixed with a mixer. When laying subsequent blocks, each block must be pressed.

Plastering walls made of aerated concrete blocks

Absolutely any plaster will do.

Dents or chips are filled with the mixture. Then the dust is removed from the wall and a primer is applied.

After the primer has dried, you can apply the plaster. You can level the plaster with a trowel or roller.

After applying the first layer of plaster, press into it reinforced mesh, which is not afraid of alkali. The next layer of plaster is applied on top.
