Problems solved by technology

Due to the large loading range of the structural column, it bears pressure, pullout force and horizontal thrust at the same time. However, when the above-mentioned existing structure bears load, especially when bearing pullout force and horizontal thrust, it is easy to cause the base to arch and deform, which affects the X of the top of the steel pipe column. The strength of the pin bearing joint

Embodiment Construction

[0031] Such as figure 1 , 2 , 3, 4 shows the steel pipe column column top X-shaped pin shaft support node embodiment of the present invention, it includes steel pipe column 5, X-shaped casting 1, node plate 2 and rib plate 3, X-shaped casting 1 is arranged on the steel pipe column 5. The top, X-shaped casting 1 is a steel casting with a thickness of about 100mm.

[0032] The X-shaped casting 1 comprises an X-shaped casting upper part 7 and an X-shaped casting lower part 6, and the height of the X-shaped casting lower part is greater than 1 / 3 of the height of the X-shaped casting. The upper part of the X-shaped casting is located above the top of the steel pipe column, the lower part of the X-shaped casting is located in the steel pipe column, and the lower part of the X-shaped casting radially extends to the inner wall of the steel pipe column and is welded with the inner wall of the steel pipe column (see Figure 4 Welds in 4).

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...
