Bifurcated node of steel pipe structure tree column with two-way stiffened plate

Abstract

The invention belongs to the field of construction engineering, and in particular relates to a tree-shaped column bifurcation node of a steel pipe structure with a two-way stiffening plate, comprising a steel pipe structure, a node end plate and a two-way stiffening plate, and the two-way stiffening plate is included in the main rod. A plurality of transverse annular stiffening plates arranged in parallel and a plurality of vertical stiffening plates perpendicular to it and extending out of the main rod and the pipe wall of the support rod intersect. The invention effectively increases the stiffness of the joint by welding the bidirectional stiffening plate in the tree-shaped column node of the steel pipe structure, reduces the stress concentration at the intersecting part and the deformation of the member, and has the advantages of simple structure, low engineering cost, wide 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.
