Integrated light truss beam composite floors and plug-in type connecting structure thereof

Abstract

The invention discloses integrated light truss beam composite floors and a plug-in type connecting structure thereof. The integrated light truss beam composite floors and the plug-in type connecting structure thereof comprise the composite floors, a steel pipe column, column end reinforcing sleeve pipes and connecting pairs. The steel pipe column comprises large square steel pipes, the large square steel pipes are sleeved with two groups of column end reinforcing sleeve pipes, and large flange plates are correspondingly welded to the upper ends and the lower ends of the large square steel pipes. Four groups of small square steel pipes of the composite floors are inserted into the large square steel pipes and are correspondingly screwed with the side walls of the large square steel pipes and the side walls of the column end reinforcing sleeve pipes through the connecting pairs, and 1 / 4 flange plate combinations arranged at the upper ends and the lower ends of the four groups of small square steel pipes are fixedly connected with the large flange plates through the connecting pairs. According to the integrated light truss beam composite floors and the plug-in type connecting structure thereof, under the premise of ensuring that connecting joints have larger connecting rigidity, the integration and factory prefabrication of the composite floors and truss beams are realized, the assembly rate and construction speed of a steel structure are improved, and assembly units are all connected by bolts to facilitate the assembly, disassembly and movement of the structure.

Description

technical field [0001] The invention relates to the technical field of assembled beam-column connection nodes, in particular to an integrated light truss-beam composite floor slab and its plug-in connection structure. Background technique [0002] Steel structure medium-pressure steel plate composite floor slabs are widely used, among which concrete is often cast-in-place, which greatly affects the assembly rate of the steel structure, increases the construction period, and makes it difficult for the quick-installation characteristics of the steel structure to be realized. The integrated composite floor and truss girder factory prefabrication can essentially solve the above problems. Contents of the invention [0003] The object of the present invention is to provide an integrated light truss beam composite floor and its plug-in connection structure, so as to realize the factory prefabricated production of the integrated composite floor and truss beam. [0004] To achieve...
