Stairs
Eelement building, which enables communication between the different levels.
Stairs usually consist of several elements. A dozen treads based on the cheeks, two, three posts and railing. However, the naming and defining the individual elements of the stairs - often varies in different parts of the country.
The degree of stair consists of two elements: horizontal called the tread, foot rest or move, and called the vertical risers, risers or elevation. From this definition it is clear difference between the terms and degree of tread, the degree is a broader term.
A series of steps creates a stair run. The theory says the stairs that the minimum run is 3 degrees, the maximum - 18, wherein the gear should not exceed 15 degrees.
A horizontal elements that allow for a possible relaxation, a change of direction speed landings (platforms).
Cheeks are usually called the cheeks, or wangami (or a revamped version of wang: wengami) sometimes boczkami or shunts. The biggest problem is understanding the terms of the type cheek. Usually we deal with stairs, where the treads are die-cut in the cheek (cheeks cheeks full or closed) or when the treads are on the cheeks (cheeks toothed, cheeks open).
An important part of the stair railing is also known as a balustrade. The task of the handrail (balustrade) is to protect against falling and assistance (support) when entering and descending. A special type of handrail is handrail that is mounted directly on the wall.
