Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to a composite shear structure for prefabricated steel structure buildings. Background Technique

[0002] A prefabricated building refers to a building in which a large amount of on-site work in the traditional construction method is transferred to the factory. Building components and fittings (such as floor slabs, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory and transported to the construction site of the building, and are assembled and installed on-site through reliable connection methods. What does the shear wall structure mean? It refers to using reinforced concrete slabs to replace the beams and columns in the frame structure, bearing various internal forces caused by the outside world, effectively controlling the horizontal force of the structure, and at the same time it also has good integrity and spatial effect.

[0003] A steel structure is a structure composed of steel materials and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of profiled steel and steel plates, and rust removal and anti-rust processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are adopted. Welds, bolts or rivets are usually used to connect between each component or part. Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings, bridges and other fields. Steel structures are prone to rust. Generally, steel structures need to be derusted, galvanized or painted, and need to be maintained regularly. During the construction of existing steel structure shear walls, when encountering walls with a large span, their stability is poor, and it is not convenient to add auxiliary steel in the walls. Therefore, we propose a composite shear structure for prefabricated steel structure buildings to solve the above-mentioned problems. Content of the Utility Model
