## For what purpose is it necessary to calculate the ladder

Whether it is a ladder in an entrance or a private house, the health of the going depends on its safety and comfort. For example, stairs too steep and not wide steps can slip, and if the height of the riser is insufficient, it is easy to catch the shoes by the step and lose balance. To avoid unpleasantness, the parameters of the steps and the ladder march need to be carefully calculated

For self-calculation, today, use formulas, computer programs, online calculators. With any calculation of the parameters of the stairs, one should be guided by GOSTs, "Standards and norms of construction", where the optimal values ​​for the construction of a convenient and reliable design of any type, the possibility of installing additional equipment, shields on the spans.

## How to calculate a ladder in a private house

In order to design a staircase in a house you need to accurately measure the ceiling opening( its width and length), the height of the ceiling.

When planning the construction of a conventional ladder, you should consider:

• Room dimensions and types of stairs( in small houses, it will be more logical to use curved staircases);
• Interior and general stylistics of the room( for example, the classic interiors can be supplemented with a wooden staircase, and for loft-style design);
• Material, technology for the manufacture and installation of stairs;
• Direction of movement;
• Necessity and possibility of installation of supports. Calculation of the staircase in a private house starts with the measurement of the room

If the house is under repair, it should be taken into account and how the dimensions of the room will change after the completion of the repair work. As an example, finishing the ceiling and floor can affect the distance between the floors. In addition, in calculations, it is necessary to take into account the thickness of the ceiling. If this is not done, the last step can create with too little overlapping or, conversely, too high a step, which will lead to knocking down at a step, slipping of the leading leg and, accordingly, to injuries. In addition, the assumed height of the lumen should be taken into account: an insufficient height will cause the person to bend down while climbing and descending the stairs, creating discomfort.

## Example of calculating the length of the ladder, the height and the width of the steps

The initial calculation stage involves calculating the number of steps. To do this, take the height of the ladder( the distance between the tiers of a clean floor of two floors) and divide it into the height of the riser chosen from the optimum values ​​- from 12 to 20 cm. The rounded value obtained will be equal to the number of steps in the march.

There should not be less than three or more eighteen steps in one ladder.

Knowing the height of the step, you can determine its width. To calculate the value, the following example should be used: x = 47 - y, where x is the width of the step and y is the height. The height and the width of the steps must be exactly the same, otherwise the different-sized steps will be knocked down, which can lead to injuries.

The width of the stitches in the curved staircase, in the narrowest part, should not be less than 140 mm.

The number of steps is the graphic projection of the horizontal length of the ladder.

In order to calculate the length of the march it is necessary: ​​

• Project the length of the ladder into a square and add to it the distance between the levels of the floors;
• Extract the square root from the value obtained.

When calculating for a ladder with a platform, note that the length of the platform should be more than 14 cm, and the width should be equal to the width of the march.

## The formula for calculating the ladder: determine the angle of inclination

Calculate the optimum angle of curvature of the ladder by the formula: 2c + d = 580/660, where c is the height and d is the width of the step. When calculating the curvature of the ladder with steps less than 14 cm in height, the formula: c + d. The angle of inclination of the structure depends primarily on the width of the step and the height of the riser

For typical stairs, there is a "Table of recommended parameters" that contains the values ​​of the angle of inclination of the march, depending on the width and height of the step, the purpose of the ladder.

The angle of curvature for specific marches is calculated taking into account the number and height of the steps.

## How to calculate the ladder with your own hands: advice on the design of the screw structure

The spiral staircase is an ergonomic and practical way of moving from floor to floor. In addition, this design can act as a decorative element for high-tech interiors, loft and minimalism.

In order to calculate the diameter of the spiral staircase, you must multiply the width of the march by two and add the resulting value to the base diameter. To calculate the radius of ascent, divide the width of the march by two and add the radius of the support to the obtained value. The basic dimensional characteristics of the spiral staircase are calculated on the basis of the diameter of the supporting pipes and the width of the march.

In order for the staircase to be comfortable, its width should not be less than 800 mm: this will allow two people to walk comfortably along the stairs.

The number and height of the steps for the spiral staircase is calculated taking into account that one turn of the structure ensures comfortable movement of a sufficiently high person( the number of steps in the coil is equal to the length of the trajectory of movement divided by the width of the step).

To calculate the height of the riser, add the average depth of the tread( 20 cm) to the average height of the adult( 1 m 80 cm) and divide the result by the number of steps in one turn. The resulting value should be divided and the height of the stairs. This value will be equal to the number of steps in the spiral staircase.

## What you need to calculate the ladder to the second floor

On the second floor can lead as a curved( screw, angular, etc.) ladder made of metal, and straight( marching) from the solid wood. Most often, for cottages and private houses use stairs with turns. The main advantage of such designs is space saving. Calculation of the structure leading to the second floor depends on the characteristics of the room and the style features of its interior.

For the calculation of the interstore ladder, it is necessary to know the following values:

• Height and length of the ceiling aperture;
• The width of the ladder;
• Total number of stages;
• Number of rotary and lower stages;
• Desired configuration of steps;
• The location of the entrance door.

In addition, it will be necessary to determine the position of the upper stage with respect to the second floor( below the floor level or level with it).

You can calculate the ladder in a private house either independently or using an online calculator.

## Calculator for calculation of ladders

Calculator is a program that allows you to calculate the most important quantities yourself for designing a comfortable and safe staircase. The result of working with the online calculator is a visual drawing that you can then print

Today, many sites related to construction offer their versions of the online calculator, each of which has features that are primarily related toInterface and a way to demonstrate the result. For example, some calculators, after the calculation, provide a complete diagram of the ladder with all the required quantities. Such a drawing can be easily saved to a computer and printed. There are also online programs that allow you to calculate the cost of cleaning stairs( washing stage, supports) in residential and commercial premises, depending on their parameters. You can use the programs on devices with platforms android, ios, windows.

## How does the ladder calculator work online?

It is quite easy to use the online calculator: for the accurate calculations, it is necessary to select the required type of ladder( straight, U-shaped, L-shaped, etc.) and enter the initial characteristics of the room.

The following mandatory parameters are required for calculation:

• Height and length of the opening;
• Number of stages;
• Desired configuration of steps( tread width, overhang size, riser height). When you enter the correct initial values ​​in the online calculator, you will get an accurate calculation of the desired ladder model

In addition, depending on the type of ladder you may need to enter additional data. For example, for a spiral staircase, you will have to specify the angle of rotation, the outer and inner diameter of the ladder, and for a design with a rotation of 180 degrees - the width of the ladder, the total and the number of lower steps. Some calculators are able to calculate the values ​​taking into account the characteristics of different materials( wood, stone, reinforced concrete, etc.).For example, Zhytov's construction calculator.

Most online calculators have visual clues-pictures with the designation of the quantities that need to be entered.

## Calculation of stairs: program for 3D modeling

Technical developments are not standing still: today we have the opportunity to get 2 and 3D model of any subject.

The computer way makes it possible to get an exact two- or three-dimensional model of the future ladder, to designate the ways of mounting the ladder( SNIP system, welding, etc.), suitable for the calculation of estimates, will allow to understand what the staircase in the interior will look like. The calculation methodology of all programs is based on compliance with GOST and norms. You can get 2 or 3D models of stairs using specialized modeling programs

The programs differ in interface language, the availability of data entry tools and stair components( some programs can include the type of riser, kosour, string, Rails, pillars, etc.), the possibility of modeling stairs from various materials( wood, stone, reinforced concrete, etc.).

Some services provide online modeling capabilities: for example, Lesenka.ru.
