Background technique

Prefabricated steel structure is a structure made 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 steel sections and steel plates. The components or parts are usually connected using steel beam connection structures.

Although the existing steel beam connection structure can be used for daily steel structure connection operations, in actual use, the steel beam connection structure usually requires multiple people to assist in stable installation, and it is inconvenient to perform installation pretreatment on the steel beam connection structure, so that the connection structure is prone to position displacement during welding or fastening with bolts, requiring multiple workers to hold it by hand for stability, which increases the labor intensity of the workers. In addition, the steel beam connection structure only relies on the connection for stability. After long-term use, the uneven force in the middle of the steel structure can easily cause the middle of the steel structure to deform, making the connection structure insufficiently stable in use.

Therefore, a steel beam connection structure of an assembled steel structure is needed to solve the problems of high labor intensity of workers and insufficient stability of the connection structure in the prior art.
