Steel structure is composed of steel structure, is one of the types of building structure. The steel structure is mainly composed of beam steel, steel column, steel frame and other section steel and steel plate components. The rust removal and rust prevention processes such as silylation, pure manganese phosphating, water washing, drying and galvanizing are adopted. Welding, bolts or rivets are usually used to connect parts or components. Because of its light weight and simple structure, it is widely used in large factories, stadiums, super high-rise buildings and other fields.
Steel has high strength and elastic modulus. Compared with concrete and wood, the ratio of density to yield strength is relatively low, so the section of steel structure under the same stress condition is smaller, the self weight is lighter, the transportation and installation are convenient, and the structure is suitable for the structure with large span, high height and load bearing. It is suitable for bearing impact, dynamic load and good seismic performance. The internal structure of steel is homogeneous and almost isotropic. The actual performance of the steel structure accords with the calculation theory. So the reliability of steel structure is high.
The steel structure workshop includes steel column, steel beam, steel structure foundation and steel roof truss. The span of the workshop is relatively large. The steel structure roof truss is basically steel structure roof truss, and the steel roof and steel structure wall can also be maintained by brick wall. Due to the increase of steel output in China, many steel structure plants are adopted, which can be divided into light steel structure plants and heavy steel structure plants. Industrial and civil building facilities built of steel are called steel structures. The steel structure building has the advantages of light weight, high strength and long span. The construction period of steel structure is short, and the investment cost is reduced accordingly. Steel structure building has high fire resistance and corrosion resistance. Steel structure building is easy to move and recycle, no pollution.
It has good impact resistance. Many people have been worried about whether the steel structure building has good seismic performance. In fact, it's a steel structure, so it's more stable. For the earthquake magnitude more than 8 areas, you can rest assured to use. Short working hours are also an advantage. However, if such a steel structure building is built, compared with the general plant, the construction period will be greatly shortened, and the investment cost will be relatively low, which is the reason for the large number of steel structure plants. Because the steel structure workshop will not cause any pollution to the surrounding environment after demolition, it is also a good environmental protection material.
