Stairs with winder steps 90 hands. Drawings and diagrams of a winder staircase

reference

A wooden staircase with turning steps can significantly save space in the house without losing convenience and functionality. When calculating, pay attention to the optimal number of rotary steps. In my experience, 3 steps are optimal for a staircase width of 80 cm. More - the steps will be too narrow and therefore uncomfortable.

If the opening is located only above top part stairs, then the height at the turning point to the ceiling is important, in order to avoid head injuries. It must be at least 2 meters.

With this design, the width of the stairs plays an important role. Because it directly affects the convenience of turning steps. The wider the staircase, the greater the number of steps that can be used without loss of convenience.

Due to the variety of projects and designs, railings for stairs are not calculated or shown in any way in the program.

Important! Pay attention to the dimensions of the turning steps. To get the dimensions of the step, do not forget to add the size of the protrusion to these dimensions.

Calculating a stone staircase is no different from calculating a wooden or metal stairs. The main thing is to correctly calculate the size of the steps. Their height must be the same for all its parts.

Calculation of stair comfort is calculated using a formula based on step length.
A person's stride length ranges from 60 to 66 cm, with an average of 63 cm.
Convenient staircase corresponds to the formula: 2 step heights + step depth = 63±3 cm.

The most convenient inclination of the stairs is from 30° to 40°.
The depth of the steps of the stairs must correspond to shoe size 45 - no less than 28-30 cm.
The lack of depth can be compensated by the protrusion of the step.
The height of the step should be up to 20-25 cm.

The program will draw drawings of a staircase with turning steps with the main angles and dimensions.
The drawings show the general dimensions of the stairs, the markings of the top of the steps on the strings, the corners of the steps and the main dimensions of the steps themselves.

I hope the program will help you design and make a staircase for your garden or home with your own hands.

The most accurate, convenient and reliable calculation stairs with a 90 degree turn in RuNet. Based on the calculation results, you will receive all the necessary data for the manufacture of a two-flight staircase with a 90-degree rotation with detailed detailed drawings of each element and an adaptive 3D model.

90 degree turn staircase calculator with landing

Staircase with 90° turn(L-shaped staircase) is a structure of two flights located relative to each other at right angles and connected to each other by a turning platform. It is the most popular type of construction, as it has small dimensions and allows installation in openings with small area while maintaining a comfortable step height.

The stair calculator with a 90-degree turn with a platform from KALK.PRO allows you to get detailed data, necessary for the manufacture of stringers, steps, risers, platforms, railings, balusters and much more. In addition, you receive a full set of drawings of the staircase (assembled or individual elements) in different projections, and elements of the virtual scene (3D model) allow you to evaluate the structure in a given opening in real proportions and accept final decision about the need to use this particular building.

If you do not know the initial data that is necessary to calculate a 90° turning staircase, you should read the following paragraph, which presents the optimal dimensions of structural elements in private houses. Recommended reading.

We warn you that for the construction of stairs there are certain construction standards and regulations that regulate methods for calculating loads and strength, dimensions, quality of materials, etc. It is necessary to design a staircase only in accordance with these rules, which include various SNIPs and GOSTs, in order to avoid the collapse of the structure or its increased risk of injury.

Calculating stairs online with a 90° turn with a platform on our website allows you to avoid most difficulties. Possible mistakes will be highlighted in red in the “Calculation results” block.

To calculate wooden stairs, entire “convenience formulas” have been developed. In construction practice, generally accepted, most commonly used parameters for comfortable, durable and safe stairs have been formed. For example, most craftsmen use the well-known formula of the “ideal safe staircase”, which was developed several centuries ago by the architect Francois Blondel:

Formula for a comfortable staircase: 2 × h + s = 60/65 cm

• h - height of steps;
• s - length of steps.

• Stair angle. Convenient tilt angle wooden stairs between 30-45 degrees.
• Stair width. Behind optimal size The width of the flight of one flight in a private house is 90-110 cm; if there is insufficient space in a private house, the staircase can be made narrower, but not less than 80 cm.
• Height and width of steps. According to practice, the ideal step height is in the range of 15-17 cm, the optimal step width is 27-30 cm.
• Thickness of steps, risers and stringers. The elements are made from wooden planks, for a riser about 3 cm thick, for steps - 4 cm, stringers - 5-7 cm.
• Minimal overhang. The minimum protrusion of a step above the riser is 30 mm, the maximum for a wooden staircase is 40 mm.
• Number of steps. Maximum amount for one flight of stairs - 18 pieces. On average, it is recommended to use 10-12 pieces.
• Fencing. For safety reasons, the height of the railing should be higher than 90 cm.

Drawing of a staircase with a 90° turn

Also, the online calculator will prepare for you 4 drawings of a staircase with a platform: different kinds on the structure (side, top), drawing of stringers (top, bottom) - all with detailed markings.

3D model of a staircase

3D model L-shaped stairs with a platform on stringers allows you to preliminary evaluate the resulting structure in real proportions. Pay attention to the tab buttons " 3D view" With their help, you can enable or disable various elements of the virtual scene in order to design with maximum convenience.

• To zoom in/out of the structure, you must use mouse wheel.
• To rotate the structure, use left mouse button(LMB).
• To change the starting point of view, hold down right mouse button(RMB).

Many private houses, apartments, offices have an unusual layout, or limited space to place a staircase, which makes it difficult and narrows the choice of its type - standard straight staircases or rotary staircases with platforms may simply not fit.

For comfort, a staircase with winder steps, which can be easily adjusted to any layout features and building sizes. It saves usable space, looks very elegant, and if all construction requirements for the width of the steps are met, then such a staircase with turning steps is also not dangerous.

The calculation of turning stairs is somewhat more complicated than the calculation of straight stairs.
Calculation of stair comfort is calculated using a formula based on step length.
A person's stride length ranges from 60 to 66 cm, with an average of 63 cm.
A comfortable staircase corresponds to the formula: 2 step heights + step depth = 63±3 cm.

The most convenient inclination of the stairs is from 30° to 40°.
The depth of the steps of the stairs must correspond to shoe size 45 - no less than 28-30 cm.
The lack of depth can be compensated by the protrusion of the step.
The height of the step should be up to 20-25 cm.

You can also achieve the convenience of a turning staircase by changing the height of the platform.

The program will draw drawings of a turning staircase with the main angles and dimensions.
The drawings show the general dimensions of the stairs, the markings of the top of the steps on the strings, the corners of the steps and the main dimensions of the steps themselves.
