Abstract

The invention relates to an X-type pin support joint for the top of a steel pipe column. The X-type pin support joint comprises the steel pipe column and an X-type casting. The X-type casting is arranged at the top of the steel pipe column and comprises an upper X-type-casting portion and a lower X-type-casting portion. The upper X-type-casting portion is positioned on the upper side of the top end of the steel pipe column. The lower X-type-casting portion is positioned in the steel pipe column, extends radially to the inner wall of the steel pipe column and is welded to the inner wall of the steel pipe column. The improved X-type pin support joint has the advantages that directions and positions of welding joints are changed, and strength, particularly strength of bearing pulling force and horizontal thrust, of the X-type pin support joint for the top of the steel pipe column is improved.

Description

technical field

[0001] The invention relates to a building structure, in particular to a steel pipe column top node. Background technique

[0002] When the load-bearing column of the large-span roof structure adopts the joint form of "square steel pipe column + cross-shaped bifurcated support", the connection node between the column top and the bifurcated support is connected by an X-shaped pin bearing to meet the requirements of the building appearance and structure. Force demands.

[0003] The existing steel pipe column top X-shaped pin shaft support nodes are as follows: Figure 6 , the X-shaped pin shaft support includes X-shaped casting 1 and base 8, the X-shaped casting and the base are generally cast as one, the X-shaped casting is set on the upper surface of the base, the base is covered on the top of the steel pipe column, and the edge of the base is welded to the steel pipe column . Due to the large loading range of the structural column, it bears pressure, pullo...
