Steel pipe column connection node structure

Abstract

The invention belongs to the technical field of building construction, and discloses a steel pipe column connecting node structure which comprises a steel pipe column, four shear-resistant brackets and a plurality of torsion-resistant brackets, two of the four shear-resistant brackets are oppositely arranged in the first direction, the other two of the four shear-resistant brackets are oppositely arranged in the second direction, the shear-resistant brackets penetrate shear-resistant bracket connecting holes to extend into the steel pipe column, and the torsion-resistant brackets are arranged in the steel pipe column. The upper flange plates and the lower flange plates of the two shear-resistant brackets oppositely arranged in the first direction are arranged at intervals in the first direction, the upper flange plates and the lower flange plates of the two shear-resistant brackets oppositely arranged in the second direction are arranged at intervals in the second direction, and the ends, stretching into the steel pipe column, of the web plates of the four shear-resistant brackets are fixedly connected with one another. The multiple anti-torsion brackets are arranged on the steel pipe column in the circumferential direction of the steel pipe column at intervals, the multiple anti-torsion brackets and the multiple anti-shear brackets are distributed in a staggered mode, and the anti-torsion brackets penetrate through the anti-torsion bracket connecting holes to stretch into the steel pipe column. According to the steel pipe column connecting joint structure, the lateral compression bearing capacity of the steel pipe column is improved, and the integrity of a beam column connecting joint is improved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a steel pipe column connecting node structure. Background technique [0002] The connection of steel tube column beam column joints is one of the key links in the design of steel structures. The beam-column node of the frame column of the multi-storey structure transmits the shear force and bending moment of the structural slab and the structural beam to the steel tube column, so that the horizontal structure and the vertical structure can be firmly connected together, which has a great impact on the bearing capacity and stability of the whole structure. It plays a very important role. The beam-column joint forms are divided into "rice type", "cross type" or "ring plate type". The overall mechanical performance of "rice type" and "ring plate type" beam-column joints is better. , is a rigid beam-column joint form commonly used in multi-rise steel structure buildings...

AI Technical Summary

Problems solved by technology

However, the integrity of the existing steel structure beam-column joints, the lateral compressive bearing capacity and its own flexural bearing capacity are poor, and it is prone to bending, which endangers building safety.
