Competent and accurate calculation of the ladder is a guarantee of convenient and safe operation. For those who decide to manufacture and assemble the structure themselves, you need to know how to calculate the stairs to the second floor correctly. Depending on the choice of the type of ladder, the calculation can be more or less difficult. It is possible to get a functional design only if all the technical standards are followed and all the main parameters of the staircase are taken into account: length, width, angle, depth and height of steps.
So that after installing the stairs to the second floor you don’t have to find that it’s too steep or narrow, it’s very difficult to climb or inconvenient to descend, you need to ask in advance how the stairs to the second floor are calculated. To do this, you need to familiarize yourself with the types of ladder structures and requirements imposed on them.
One or another type of stairs to the second floor is chosen based on the characteristics of the building structure, the purpose of the stairs, the general style of the interior and the availability of free space for its installation.
Main types of stair structures:
Ladders installed inside a house or apartment are simple – they include straight structures, and stairs with platforms. Stairs in the house that contain several marches are right (turn clockwise) and left (turn counter-clockwise). More complex designs – rotary and spiral staircases.
The main requirements for the operation of stairs are:
Helpful advice! If the planned staircase will be in the guest room, the passage from the entrance to the staircase must be shifted to the wall of the room, it should not cross the room diagonally.
In order to calculate the ladder design, it is necessary to navigate the component parts of which it consists.
The main parts of the staircase structures include the following elements:
Helpful advice! In order for the staircase to let in more light and look rather light, it is recommended not to use the risers.
After reviewing the basic elements of the ladder structures, you can safely proceed to the calculation of the stairs, without fear of becoming confused in the concepts and names of its component parts.
For those who decide to independently calculate the stairs to the second floor, it is necessary to make a project. According to the project, you can calculate the dimensions of the structure: the length and width of the stairs, the number of steps, the angle of inclination. It is necessary to calculate the ladder consistently in order not to be mistaken in the necessary values, since even minor errors can lead to undesirable consequences during the operation of the ladder system.
The calculation of the ladder design includes several items:
Helpful advice! If the ladder has two or more marching spans located in the opposite direction, there must be a gap of at least 50 mm between them.
Considering that straight single-front structures for installation require a sufficient amount of space, in the cottages and cottages they use rotary structures with platforms or radius steps. When calculating a staircase with a platform to the second floor with a turn of 180 or 90 degrees, the device of a rectangular or square plank is taken into account, from which the turn is made by an appropriate number of degrees.
PGood advice! When calculating stairs with platforms, it is necessary to be guided by the fact that the length of the platform between the marches should be more than 140 cm (two steps), and the width should correspond to the width of the flight of steps.
When calculating the stairs to the second floor with a turn of 90 with zabezhny steps take into account the fact that the turn has three or more zabezhnyh steps.
The main requirements for the construction of turnpipes:
In the calculations of stairs with rotary steps at 180 and 90 degrees, it should be borne in mind that the tread width (steps) in the narrowest part should be at least 14 cm. Then, the width of the landing step in the middle line zone will be optimal for human movement, since This line will be the movement on the turning part of the stairs.
The design of the spiral (spiral) staircase is arranged in a circle steps, one side of which is wider than the other. The main advantage of screw systems is a significantly smaller area occupied by the ladder, in comparison with marching analogues.
Having made a competent calculation of the stairs to the second floor, you can independently make and install the structure, being sure that it will meet all the required operational standards.
