Beam column connection node structure of steel structure factory building

Abstract

The utility model discloses a beam-column connection node structure of a steel structure factory building, and relates to the technical field of steel structures. The connecting structure comprises a steel column, a steel beam is fixedly connected to the top of the steel column, a connecting and fixing assembly is arranged on the surface of the steel column in a sleeved mode, a limiting and fixing assembly is arranged in an inner cavity of the connecting and fixing assembly, and the connecting and fixing assembly comprises a connecting piece arranged on the surface of the steel column in a sleeved mode. Through holes are formed in the front ends and the rear ends of the two sides of the inner cavity of the connecting piece. Through the collaborative design of the connecting and fixing assembly and the limiting and fixing assembly, detachable connection of the steel column and the steel beam is achieved, the structural integrity and the bearing capacity are guaranteed, meanwhile, the installation flexibility is enhanced through a thread adjusting structure, a connecting piece does not need to be supported and fixed through an extra auxiliary tool, and the installation cost is reduced. The assembling efficiency is improved, the labor intensity is reduced, meanwhile, the node stress is effectively dispersed through the arrangement of the reinforcing ribs, and the anti-seismic performance is remarkably improved.
