Clothing, food, housing and transportation are the conditions of people's life, among which the living environment is particularly important. From ancient times to the present, the housing structure of people has been constantly improved and optimized with the progress of productivity and science and technology. From the beginning of thatched houses, stone houses, to the later brick houses, the buildings have undergone earth shaking changes in the shape structure, living feeling, solid stability and other aspects. Nowadays, the reinforced concrete structure has replaced the common people's buildings. The structure of this kind of house is mainly made of steel bars, and then through pouring concrete, removing formwork, ramming soil, changing the roof to water and electricity, the building we live in now is formed.
