Square tube beam-column joint and construction method thereof

Abstract

The inventions provides a square tube beam-column joint and a construction method thereof and belongs to the field of steel structures with an aim to solve the problem that existing beam-column jointconstruction is low in efficiency and strength. The square tube beam-column joint comprises a square tube column and a beam, the column comprises four outer column plates and four inner column plates,and the inner column plates enclose to form a grouting channel; the column comprises four round tubes, each round tube comprises an inner short round plate, an outer short round plate, an inner longround plate and an outer long round plate, the outer side of the inner short round plate is adhesively fixed with the outer side of the inner long round plate of the neighboring round tube, the outerside of the outer long round plate is flushed to the outer side of the outer short round plate of the neighboring round tube to form the outer column plate, and the inner long round plate forms the inner column plate; the column further comprises an inner node plate, the periphery of the inner node plate are welded to the inner side of the inner column plate, a grouting hole is arranged in the center of the inner node plate, and each of the inner column plate and the outer column plate is provided with a running hole; the column further comprises four beam connecting tubes which penetrate therunning holes, concrete mortar is poured into the grouting channels, and ends of the beam are fixedly sleeved in the beam connecting tubes. The beam-column joint is high in strength and construction efficiency.

Description

technical field [0001] The invention belongs to the technical field of building steel structures, and relates to a square tube beam-column joint and a construction method thereof. Background technique [0002] In the steel structure buildings that are widely used at present, it is usually necessary to install the beam body on the side of the column body. The existing method generally directly connects the end of the beam body with the outer wall of the column body through connecting steel plates, which not only needs to connect multiple steel plates, but also leads to low construction efficiency. , at the same time, the connection between the steel plate and the beam and column bears a large force, and because the beam and column are hollow structures, the joint position is easy to squeeze the column and cause the column to deform, so the steel structure formed is low in strength and stable. Poor performance, affecting building safety, so it is necessary to improve. Conten...
