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.

Embodiment Construction

[0013] like figure 1 As shown, the bifurcated node of the steel pipe structure tree column with bidirectional stiffeners includes main rod 11, common strut 12, main stressed strut 13, main rod head plate 21, strut node end plate 22 and two-way stiffener Plate 3; among them: the ordinary support rod 12 is provided with multiple pieces, and the common support rod 12 and the main force receiving support rod 13 are all intersected and welded with the main rod 11; the main rod head plate 21 is a circular steel plate, and the main rod head plate 21 The top of the main rod 11 is sealed with a continuous weld seam to isolate the internal and external air; the node end plate 22 of the rod is a ring-shaped steel plate, and the non-penetrating ends of the ordinary rod 12 and the main force rod 13 are welded to the node end of the rod The plate 22 is used to reduce the stress concentration when welding with parts other than the node; the main rod 11 is provided with a two-way stiffening p...

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...
