The erected ladder in a private country house must comply with the regulated SNiP, thus guaranteeing the safety of movement. Unfortunately, non-compliance with regulatory requirements can lead to unfortunate consequences. What rules should be followed when designing stairs for the house?

Designing a staircase in a private house
The construction and installation of a staircase in a private house must begin with the development of a project, which includes the calculation data and working drawings of the arrangement of the stairs to the second floor.
For design, you can use a computer program to calculate the main elements of the staircase in a private house. However, regardless of the choice of the design of the ladder, it will not hurt to remember the basic rules and requirements that are imposed on different types of structures.
Such requirements make for the main characteristics of the stairs:
• location and location
• Dimensions of stairs
• tilt angle.
A fundamental factor can be considered the choice of the installation site, which will further affect the dimensions of the ladder, the type and angle of inclination. The preliminary stage of the design of the ladder is the measurement of the area of the proposed installation. Depending on the existing size of the installation area, you should choose and give preference to a certain type of staircase.
Recall that in the case where the area of the proposed installation is less than 3 square meters, you should choose a more economical spiral staircase. The most popular when designing staircases of a private and country house are marching staircases or stairs on the bolts. So, the dimensions of the stairs, namely the width should be understood:
• for screw types 100 -150 cm
• Marching and staircases at 120-150 cm.
Types of interstorey stairs for home
The most popular types of stairs for a private house are:
• screw
• marching
• on the hands.
Therefore, depending on the chosen type of ladder and the designation of its structural elements, it is necessary to develop a project for each specific case.
Stairs in a private house, whose projects are offered by specialized design organizations, are eventually "adjusted" to a particular house or cottage.
According to the fire protection requirements for the erection of the interstore ladder, the minimum width should be not less than 100-120 cm. The smallest permissible distance to the ceiling should be 190 cm.
Design of stairs in a private house
Certainly, the design of the stairs in the house or cottage depends on many factors, among which it is necessary to note: design features, material and color solution. Important, but rather determining is the choice of the style of the future staircase.
Modern trends in the design of stairs for a country house assume the following styles:
• Classic Classic
• neutral Simple
• Trendy Contemporary.
The choice of design style implies strict compliance with the choice of material, but in no way denies the use of decorative stucco elements, forged parts or the use of columns.
Naturally, the price of a staircase to a private house will depend on the style decision and the material in which bold design solutions are embodied. A modest ladder of a simple configuration made of wood or metal will cost "modestly", but the exclusive model is shocking at its price.
However, the design of the stairs should fully correspond to the design and layout of stairs in the space of a private house. It is noted that the most popular option is the design of the flight ladder.
This can be explained by a number of reasons: in the flight staircases the biomechanics of human displacement is optimally calculated and taken into account. For operation, the flight ladder is considered to be the safest, the calculation of staircase parameters and the subsequent installation of it are simple and accessible.

Structural elements of stairs
Any, even the most intricate versions of stairs in a private house, presuppose the presence of the basic elements:
• steps
• supporting elements: supporting beams, bowstrings and strings
• handrails or handrails.
Therefore, the process of designing a reliable ladder design must be carried out taking into account the availability of these elements.
Layout of the ladder in space
It's no secret that the arrangement of the interstorey staircase in a country house depends on the size of the room and the interstorey height. To determine the overall dimensions of the projected ladder, a simple technique is used: the height of the wall to which the ladder is to be measured is measured. A rectangular triangle is supposed to be built, presumably with one wall being a pedestal, the other leg being a floor, and a hypotenuse going up the ladder march.
Therefore, the layout marks in the working drawings will be tied to the floor mark, available march areas and the end of the last march to the second floor. In the layout drawing, a projected turn of the ladder at an angle of 45, 90 or 180 degrees should be shown. The desired turn is provided by areas having simple geometric shapes.
How to calculate the number of steps, their width
Structurally, the steps consist of two separate parts, namely treads and risers. The tread is a horizontal working surface, the size of which is chosen relative to the convenience of placing the foot when walking (downhill). Long operation of the steps determined the most comfortable size of the tread. It is about 30 cm.
The vertical part of the step is a misfire, whose height can be up to 20 cm. Therefore, the calculated width and height of the stairs in the house depends on the size of the tread and riser. It is difficult to calculate the width and height of the ladder. The only feature will be the presence of rotational degrees. Calculation of ladders with turning steps is averaged, taking into account their optimal number.
Calculation of the comfort of the staircase is calculated by the formula, which takes into account the length of the step. The average value of the step length is 63 cm. Thus, the dimensions of the steps are comfortable and comfortable, the ladder is calculated by the formula:
two step heights + step depth. The recommended step height can be up to 25 cm.
