Beam through mortise and tenon type node structure of assembly type steel structure and assembly method of node structure

Abstract

The invention relates to the field of assembly type steel structure buildings, in particular to a beam through mortise and tenon type node structure of an assembly type steel structure and an assembly method of the node structure, and the produced beam through mortise and tenon type node structure can be taken as the node applied in the assembly type steel structure building. The structure comprises through main beams, main beam upper flanges, main beam lower flanges, main beam webs, cut auxiliary beams, auxiliary beam upper flanges, lower beam lower flanges, auxiliary webs, auxiliary connection dowels, 1 / 4 mortise and tenon steel pipe columns, upper mortise and tenon grooves, lower mortise and tenon grooves, splicing partition plates, ordinary steel beams and ordinary steel pipe columns. According to the beam through mortise and tenon type node structure of the assembly type steel structure and the assembly method of the node structure, the main beams, the cut auxiliary beams and four 1 / 4 mortise and tenon steel pipe columns are connected. According to the structure and the assembly method, the building space is saved, the force transmission path is clearer and more reliable, the construction is simple and convenient, the actual engineering design and construction requirements are met, the welding workload is small, environment protection and energy saving are realized, and the current requirement for green buildings is better met.

Description

technical field [0001] The invention relates to the field of prefabricated steel structure buildings, in particular to a prefabricated steel structure with beams interspersed with mortise and tenon joints and an assembly method. The produced beams intersected with mortise and tenon joints can be used as joints used in prefabricated steel structures. Background technique [0002] The prefabricated building has the advantages of environmental protection and fast construction speed, and has become one of the important directions of future construction development. The prefabricated steel structure is one of the important components of the prefabricated building. In the past, in the prefabricated steel structure, the beam-column joints were mainly connected by welding, and the force between the beam-column was transmitted by the weld seam. This kind of joint has many disadvantages, such as: high welding quality requirements, complex construction, large welding quality affected b...

AI Technical Summary

Problems solved by technology

This kind of joint has many disadvantages, such as: high welding quality requirements, complex construction, large welding quality affected by human factors, large residual stress in the weld and around the weld, and the seismic performance is greatly affected by the weld. At the same time, if the beam is not connected For columns, the size of the reinforcement ring for auxiliary joint force transmission is large. If the beam penetrates the column, the root of the column needs to be welded with the beam, and the seismic performance of the joint is poor
