Steel pipe structure tree-shaped column bifurcated joint with bidirectional stiffening plates

Abstract

The invention belongs to the field of constructional engineering, and particularly relates to a steel pipe structure tree-shaped column bifurcated joint with bidirectional stiffening plates. The steelpipe structure tree-shaped column bifurcated joint with the bidirectional stiffening plates comprises a steel pipe structure, joint end plates and the bidirectional stiffening plates, wherein the each bidirectional stiffening plate comprises a plurality of transverse annular stiffening plates arranged inside a main rod in parallel and a plurality of vertical stiffening plates which are perpendicular to the transverse annular stiffening plates and extend out of the main rod to intersect with the pipe walls of supporting rods. According to the steel pipe structure tree-shaped column bifurcatedjoint with the bidirectional stiffening plates, the bidirectional stiffening plates are welded in the steel pipe structure tree-shaped column joint, so that the rigidity of the joint is effectively improved, stress concentration and rod piece deformation of intersecting parts are reduced, and the steel pipe structure tree-shaped column bifurcated joint has the advantages of being simple in structure, low in engineering cost, wide in application range and the like.

Description

technical field [0001] The invention belongs to the field of construction engineering, and in particular relates to a bifurcation node of a tree-shaped column of a steel pipe structure with two-way stiffening plates. Background technique [0002] The tree-shaped column of steel pipe structure is a special-shaped vertical component in construction engineering. It has a beautiful shape, and each column can support a large area of ​​roof structure. In recent years, its application in some public buildings at home and abroad has gradually increased. At present, the bifurcated nodes of the main and support rods of the steel pipe structure tree-shaped column adopt cast steel nodes or large-scale welded hollow ball nodes when the connection is particularly complicated. Most projects still use the method of multi-tube direct intersecting welding. The intersecting parts of the struts have obvious stress concentration, which is the weak part of the force. Therefore, in order to ensure...

Problems solved by technology

At present, the bifurcated nodes of the main and support rods of the steel pipe structure tree-shaped column adopt cast steel nodes or large-scale welded hollow ball nodes when the connection is particularly complicated. Most projects still use the method of multi-tube direct intersecting welding. This method mainly, The stress concentration phenomenon is obvious at the intersecting parts of the struts, which are the weak parts of the force. Therefore, in order to ensure the reliability, the cross-section of each rod is often designed to be large and thick, which affects the economy and aesthetics.
