Abstract

The invention relates to a joint structure for rigid connection of steel structure beams and columns, a manufacturing method of the joint structure and a residential structure system. The joint structure for rigid connection of the steel structure beams and columns comprises a central joint, steel beams, beam web splicing plates and upper and lower steel columns; the central joint is welded and prefabricated at a factory and composed of a bottom plate, a cover plate, a column web, beam webs and stiffening ribs. Steel columns, steel beam flanges, the webs and the central joint are all connectedthrough high-strength bolts. According to the joint structure, the process of on-site butt joint penetration welding of bolt-welding connection joint flanges is omitted, and the full bolt assembly ofthe beams and columns and the joint on the construction site is achieved; compared with a traditional full-bolt-connection joint, the number of bolts at the joint flanges is reduced by half; the put-aside lap joint mode of the flanges facilitates the construction in-position and bolt connection of the beams, and the construction speed is increased; in addition, the beams at the joint are through,and the stress is reasonable; the factory standardized prefabrication production is achieved; the on-site assembly is convenient and fast, and the construction speed is increased.

Description

technical field [0001] The invention relates to the technical field of building structure node connection, in particular to a node structure for rigidly connecting steel structure beams and columns, a manufacturing method thereof, and a residential structure system. Background technique [0002] The beam-column central joints of steel structures stipulated in the existing codes and widely used in engineering are bolted and welded joints (the structure of which is as follows: Figure 1a shown), specifically flange butt penetration weld connection and web high-strength bolt connection. Its characteristic is that the column is connected at the node position, and the inner diaphragm is set at the beam flange position in the column, and the flange connection is a butt penetration weld. % weld inspection. In addition, there are fully bolted beam-to-column joints (whose structure is as Figure 1b shown), specifically the flange is also connected by bolts, and the number of bolts ...
