Parts of a building

Almost everyone saw the construction of a building and followed its progress with interest.

First the excavation 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, roof s and other parts of the building must be carefully designed and proportioned.

The architect or designer must decide, what the size of the walls, thefloors, 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 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.
