Connecting joint of flat steel tube concrete column and steel beam and construction method

Abstract

The invention discloses a connecting joint of a flat steel tube concrete column and a steel beam and a construction method, and belongs to the technical field of fabricated steel structures. The connecting joint is provided with mounting frames, connecting frames, inner plate frames and side edge frames, wherein connecting parts on the mounting frames are in transition fit with the side edge frames to realize left and right fixation of the mounting frames, holes in the side edge frames and the connecting parts are connected into a whole through bolts to realize overall position limitation and state stability, then the two mounting frames are assembled through the bolts, convenience and rapidness are achieved, and the stability and reliability are high. According to the connecting joint, through the design of the steel structure bolted by the bolts, the mounting speed is higher, the construction quality is easy to control, meanwhile, weld joints generated by field welding are avoided, so that the anti-rust paint surface outside a flat steel tube is kept complete, the possibility of corrosion state occurrence is reduced, meanwhile, the positioning precision is enhanced, and the construction convenience is improved.

Description

technical field [0001] The invention relates to the technical field of fabricated steel structures, in particular to a connection node and a construction method of a flat steel tube concrete column and a steel beam. Background technique [0002] The prefabricated steel structure has the characteristics of standardized design, factory manufacturing, assembly construction, decoration integration and information management, which can effectively reduce the labor intensity on the construction site and shorten the construction period. It is a green building with a full life cycle. There is no wet work, which can significantly reduce construction dust and dust, and significantly reduce the pollution caused by construction. Prefabricated steel structure buildings have become an important construction method in developed countries such as Europe, America and Japan, and are also a new source of contemporary Chinese architectural development. [0003] Prefabricated steel structure be...

AI Technical Summary

Problems solved by technology

[0004] In the existing prefabricated steel structure, the flat steel tube concrete columns, the connection nodes of the steel beams on it are basically connected by plug-in plates, which need to be fixed by on-site welding during the period. The on-site welds are damaged due to the paint surface, which is easy for the steel structure The main part where corrosion occurs, and the corrosion of fabricated steel structures is an important threat to building safety
