Internal stairs: the division in the direction of the axis of the stairs, the materials used, according to the fire
Internal stairs to the second floor in private homes are not only essential detail of the interior, but also contribute to it beauty and attractiveness.
Such structures can be of various types, the choice of which is determined by the size of the room design, the wishes of the owners.

An internal staircase to the second floor - a luxurious composition of wood and metal
Types of internal stairs
The division in the direction of the axis of the stairs
By the way directed center line, an internal staircase to the second floor there is a straight line and turning. It is called the line, if the center line of its direction does not change, it does not matter, there is a playground on it or not.

Direct construction on the second floor - make it short
Such ladders Housing easy to manufacture and safe in operation. But having undoubted advantages, straight ladders, with long, take up a lot of valuable space premises. In the case of changing the direction of the axial line, referred to as rotary.

Swivel design for private house
If we see a divergence in the different sides of staircases, after platforms, it is called a ladder swing.
The way changes its direction of the center line, define the left and right swivel design. The direction of rotation is determined by the layout of the room, and each case is individual.
Ladders are constructed with a turn in the event that needed saving valuable floor space. But the presence of turns leads to the fact that the ladder is not so convenient to use and navigate through it is not as safe. Therefore, their number is minimal.
During the construction of individual houses are the most common rotary design of stairs with two marches.
If there is a turning staircase staging area, then construct the so-called winders. These are the steps for interior staircases, whose width is less than the inside of the outer.
Winders on a rotating ladder
Unless winders are used to create a ladder structure, then it is called a spiral.

A spiral staircase design - a very original solution
Splitting the materials used
In the manufacture of ladders can only be used concrete, metal, wood or they may be combined.
The material is selected on the basis of that, what are the stair designs, the place of its installation, operating conditions and the design intent.
1. Internal concrete stairs.

The monolithic concrete structure - strong and durable
These stairs are divided into monolithic and modular, which includes concrete beam and a certain amount of type-setting steps. In the manufacture of such special steps are used to form concrete. Monolithic constructions are made with a special formwork, installed directly where will be located the future design.
