Description

Technical Field

[0001] The utility model relates to the technical field of steel structure connection, in particular to an assembled steel structure connection mechanism. Background Art

[0002] 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 beams, steel columns, steel trusses and other components made of steel sections and steel plates. When the steel sections are used to connect two sets of steel plates, the steel sections are installed in an L-shape through angle plates and bolts at the contact points of the steel sections, so that the steel plates of the steel sections can be assembled.

[0003] When assembling the prefabricated steel structure steel in the prior art, a simple L-shaped angle plate is usually used with bolts to assemble and lock the steel with another set of steel on the inner concave surface. This simple installation structure usually only installs two sets symmetrically on the inner concave surface of the steel. When the steels are subjected to force, the connection locking surface of the steel is small, resulting in poor connection firmness between the steels. For this reason, we propose an assembled steel structure connection mechanism. Utility Model Content
