device stairs is very diverse, from the whimsical to the practical design of strict construction. Straight stairs are quite simple in design, however, this does not deprive them of grace and beauty. Stairs with straight marches are diverse in their kind and materials of manufacture.

direct staircase to second floor staircase
direct is a subspecies of propulsion designs. In addition to direct lines, there are several subspecies in the form of marches, all of them are inherently direct. The staircase to the second floor of the straight has one march of steps and may not have a platform on the top.
Ladder structure has the following parts:
- Under risers;
- Kosoura or string;
retaining structures stairs stringers or string. Beams sawtooth with a horizontal cut for the steps are called oblique. The supporting kosor can be one, then the support of the steps of the second side is made to the wall, this design is called the wall.
A ladder on two supports is called central. Beams with grooves for steps and steps are called strings, they are made of a well-dried thick board. The staircase can be, with or without cushions, they perform a more decorative function. Balusters and handrails are necessary for the convenience of lifting and decorating the edges of the stairs.
The construction of a straight ladder on two oblique legs is quite simple for self-manufacturing.
The most popular design is angled staircases. Most often, the staircase angular has a turning staircase around two straight marches. The corner L-shaped ladder is installed in the corner of the room and saves a lot of square meters. In addition, this design is convenient for walking.
The material for manufacturing is different:
- Most often, the angular staircase is made of wood;
- Metal construction is also not uncommon, it is quite strong;
- Sometimes the ladder design is made of a combination of different materials, for example, wood - metal, metal - stone or wood - stone.
Wooden construction is quite simple in execution and can be executed independently. The corner staircase can be U-shaped, in this case the turntable is oriented at 180 degrees. In the corridor this kind of design looks perfect.
Do not forget about the requirements of GOST for stairs and platforms.
Types of direct ladders
In modern times, the ladder is not only a means of climbing to the second, third, etc.floor. Often the design is still an ornament of the interior. Types of direct stairs are different, and their application depends on the free area, height of ceilings and interstore openings.
Straight ladders are divided into:
- One-side, which have one ladder;
- Two-masted cars are L-shaped or U-shaped, contain two march lifts separated by a platform;
- Three-mast constructions are used in rooms with very high ceilings and with a large interstorey opening.
The type of ladder is selected, according to thorough calculations, it is necessary to take into account all the features of the room.
The width of the opening must be optimal, in a very narrow opening it is uncomfortable to move and it is impossible to transfer volume objects.
Straight single-ladder ladders can be located in the middle of the room, angular and multi-mast often located along the walls. A staircase is quite complicated. It does not have a platform, rotary steps are made instead of it. The gangway can be circular, this design refers more to the screw types of stairs.
Straight ladder dimensions
Straight type of ladder is quite simple, however, for installation it is required to draw a drawing indicating all the dimensions in the Autocad or Compass program by looking at the examples in the Perspective journal. The ladder straight has dimensions, both individual, taking into account the volume of the room, and general, which are taken into account regardless of the square meters and the height of the building.
General design data:
- The step width is not less than 25 cm;
- The optimum slope is 30-40 degrees;
- Depth of steps not more than 25 cm;
- One flight of stairs is 10-12 steps.
For the installation of a metal ladder, a KMD drawing should be performed. In the Autocad system, you can produce a 3D drawing of a future ladder. In addition, specialized calculators can help with calculations.
Another type of ladder is vertical. These are strictly vertical staircases with a minimum slope, consists of strings on both sides and steps. The distance between the strings is not more than 80 cm, the step step is 30-34 cm. The material of manufacture can be of two types: metal or wood. Types of vertical stairs are not very diverse, hinged or attached, that's all the difference.
