Online calculator of a ladder with a 180 degree turn: site calculation 90, turn-around and turn-by-turn program

It is possible to calculate the size of the future ladder correctly using the special calculator. No structure larger than one storey can manage without a ladder. Before beginning the installation of the ladder, all calculations must be made and a plan drawn up. A particularly careful calculation requires rotary structures. A good assistant in this is a ladder calculator online with a 180 degree turn.

How to calculate a ladder with a 180 degree platform

Calculate the ladder from the areaCoy 180 degrees can be on their own. In order for the calculations to be correct you need to know the basic requirements for stairs and platforms. These requirements are prescribed in SNiP, compliance with them is mandatory for all staircases.

If you decide to independently design and install a ladder in the house, then you need to familiarize yourself with the basic requirements of

For self-calculation, you need to know the following:

• All ladder calculations are based on the average human step length60 cm;
• The optimum depth of the steps is 30 cm, and the height is 20 cm, at these sizes it is most convenient to move along the steps;
• The slope of the ladder should not be less than 30 degrees and greater than 60, optimally 45 degrees;
• The width of the steps must be at least 25 cm, the foot of any size must have full support for the step;
• There are also requirements to the fences of the stairs, their height is not less than 90 cm, and if the house has children, then at least 120 cm.

These are the basic requirements from which further calculation is made. Stairs with a platform can be with a shortened first march that will save space. All dimensions are fixed on the drawing and must be checked with a direct installation of the structure.

Use the ladder calculator with a 90 degree turn

The ladder with a 90 degree turn is calculated according to the same principle as with a turn of 180. This is a L-shaped design with a straight or sash pad. A ladder with a direct transitional platform is called a two-march staircase. To calculate the calculator, the ladder with a 90 degree turn uses the simple Blondel formula-the width of the tread + the height of the riser = 65 cm. The calculator will perform all the necessary actions to calculate a safe and reliable design.

Using a special online calculator, you can make stair calculations with a turn of 90 degrees.

You need to know the basic dimensions and make them into the program:

• Floor to ceiling height of the ground floor;
• Length of the interstore window;
• The width of the ladder.

The calculator will execute the drawing according to the specified dimensions, determine the optimum sizes of steps and their number. When calculating the angular staircase with the stepped steps, it will also display their dimensions and the required number. This is a fairly convenient way of calculating all the designs of the stairs.

Correct calculation of swing ladders

Turning stairs have different shapes. All of them have turning platforms or turn-by-turn stages. There are U-shaped or L-shaped, differ in the number of marches - two-marsh, three-marsh or multi-marsh.

The reliability of a particular design depends on the accuracy of the calculations. Also, the calculation depends on the material of the construction.

It is necessary to take into account absolutely all the parameters and features of the structure of the house.

The correct calculations will help make the ladder practical and safe

Calculation of various elements of the ladder can be done in several ways:

• Calculation and drawing in the manner of proportions;
• Drawing execution by applying the main lines;
• Calculation of the runway stages.

Each of these methods involves building a drawing yourself. This step should be approached responsibly, all steps of the ladder should be the same. It is desirable to perform an odd number of steps in one march - this is convenient when climbing and descending from the stairs.

Calculation program for turning stairs

Turning stairs are very popular, their design takes up a small space. They are also convenient to use and can carry large objects. The calculation will help to produce a program for calculating turnstiles.

In order to make a calculation of the turnstile, you should use the specially designed

. For calculation, the following dimensions must be entered in the dedicated windows of the program:

• The length of the aperture;
• Opening height;
• Width of the ladder;
• Thickness of steps;
• The size of the ledge step.

The program will calculate all necessary parameters and draw a drawing. There are three formulas for calculating ladders, they can all be applied by the program. The safety formula will calculate the most optimal parameters for operating the ladder.

The convenience formula will make the drawing as convenient as possible. The most popular formula Blondel produces the main parameters.

Calculation programs using all three formulas show the most accurate results. It is worth remembering that it is undesirable to equip a ladder march with too many steps, it is very difficult to climb these stairs. The optimal number of steps in one march should be no more than 15, ideally 11. Marches with less quantity are located in the lower part of the structure.

Turning ladder to the second floor with your own hands

The design of the turnstile is simple. You can make a beautiful and sturdy staircase with your own hands. First you need to determine what kind of species it will be, then select the material. The most convenient for self-assembly is wood. If you choose a wooden staircase, it is important to choose a variety of wood for its manufacture.

Stairs are made of hardwoods: oak, maple, larch, beech. The budget option may be pine wood.

You can make and install the ladder in your house with your own hands, the main thing is to make the correct calculations and pick up high-quality materials

After choosing the wood, it is necessary to make calculations. The simplest and most reliable way of calculating the ladder is to use the online calculator. The drawing made by the program can be printed on the printer for convenient use.

The next stage will be the preparation of the necessary tool for installation works:

• Construction level;
• Hacksaw for wood;
• Screwdriver;
• Elbow;
• Electric jigsaw.

All wood materials must be thoroughly dried and treated with antiseptic solutions. When all materials are prepared, you can proceed with installation.

The entire process can be divided into the following stages:

• Installation of load-bearing elements;
• Installation of steps and risers;
• Installation of enclosing elements.

It is important to follow all calculations performed by the online program strictly during installation. After the installation is complete, the final finish of the staircase should be made. Design of noble varieties of wood is better covered with varnish, which will preserve the natural pattern and color. Care for the wooden structure has its own characteristics. Avoid excessive wetting, exclude aggressive detergents, wash the construction should be moderately wet cloth and wipe dry. With proper installation and maintenance, the turnstile will last for many years.
