Parts of a building Нужен превод плиз срочно
Almost everybody saw the construction of a building and followed its progress with interest. First the excavation is dug for the basement, then the foundation walls below ground level are constructed; after this the framework is erected and clothed with various finishing materials and protected by several coats of paint.
The part upon which the stability of the structure depends is the framework. It is intended for safety carrying the loads imposed. The floors, walls, roofs and other parts of the building must be carefully designed and proportioned.
The architect or designer must decide what the size of the walls, the floors, the beams, the girders and the parts, which make up the framework, will be and how they will be placed and arranged.
Here are the main parts of a building and their functions.
Foundations serve to keep the walls and floors from contact with the soil, to guard them against the action of frost, to prevent them from sinking and settling which cause cracks in walls and uneven floors.
Floors divide the building into stories. They may be either of timber or may be constructed of a fire-resisting material. Walls are built to enclose areas and carry the weight of floors and roofs. The walls may be solid or hollow. The materials used for the walls construction can be brick, stone, concrete and other natural or artificial materials.
Roofs cover the building and protect it from exposure to the weather. They tie the walls and give strength and firmness to the structure.
