Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, and more specifically, to a prefabricated steel structure with good wear resistance effect. Background Technique

[0002] A steel structure is a structure composed of steel materials and is one of the main building structure types. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of sections and steel plates, and rust removal and rust prevention 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 the components or parts. Because of its light self-weight and simple construction, it is widely used in large factories, stadiums, super high-rise buildings and other fields. In order to extend the service life of the existing steel structure, various coatings will be applied on the surface of the steel structure to meet different use requirements. However, the steel structure will be worn to varying degrees during transportation and installation, resulting in damage to the paint surface, so that the expected effect cannot be achieved. For this reason, a prefabricated steel structure with good wear resistance effect is proposed to solve the above problems. Content of the Utility Model
