Problems solved by technology

However, while bringing convenience, the prefabricated structure still has its own shortcomings. The seismic resistance of the structural nodes is not high, which is not good for the structure's seismic resistance and is prone to damage.

Abstract

The invention discloses a combined prefabricated steel structure anti-seismic connection joint, which comprises a prefabricated steel beam column, a prefabricated steel beam, web base plates, and first high-strength bolts. Stiffening ribs are arranged on the prefabricated steel beam column and the prefabricated steel beam. A web of the prefabricated steel beam column and a web of the prefabricatedsteel beam are both provided with first installation holes. Second installation holes are formed in the web base plates, wherein the second installation holes and the first installation holes are equal in number and size. The web base plates are symmetrically installed on the two sides of the web of the prefabricated steel beam. The first high-strength bolts sequentially pass through the second installation holes and first installation holes of one web base plate, and are fastened through the second installation holes of the other web base plate. The combined prefabricated steel structure anti-seismic connection joint is simple in structure and excellent in anti-seismic property.

Description

technical field [0001] The invention relates to a connection node of a building structure, in particular to an anti-seismic connection node of a combined prefabricated steel structure. Background technique [0002] Steel structure is known as "green building in the 21st century", so it is a better choice to apply steel structure to prefabricated nodes. For complex steel structures, the seismic performance of joints is very important. The failure of a single member will not cause the destruction of the entire steel structure system, but the destruction of complex nodes will cause the destruction of the entire structure. Therefore, at this stage, the seismic resistance of node connections is still a difficult problem to be solved urgently. [0003] With the development of the times and the continuous advancement of technology, prefabricated components and factory prefabricated on-site installation bring great convenience to construction. However, while bringing convenience,...
