Open staircase made of wood can be odnomarshevymi (March — a series of steps that are between two sites), when in contact with the march one of the walls; — pace when marches are contiguous along the walls and form a right angle; multifaceted. Kind of stairs selected depending on the area of ??the premises. Regardless of the design ladder should first and foremost be safe and comfortable.

In this case, they will not be concave. Stringers (parts ladder for fixing steps) made of planks with a thickness of 3.5-5 cm, and tightening the tightening diameter of about 1.2 cm for sites like treads to take the board thickness of 2.4 cm for podstupenek — thickness 1.8 cm and a width of 15-17 Bond steps and tread with stringers and stringers (parts of stairs, which are used to mount the steps by plunging them into the flank) in various ways. Some of them are shown in Fig. 58. Fig. 58. Mounting methods and steps to tread stringers To ladder was stable it is attached to the floor and upper part of the wall. Number of steps in the march must be odd — 3 or more. The most simple in execution and production are stairs with a straight march.
