Embodiment

[0027] Example: such as Figure 1-4 As shown, the fabrication method of the isosceles triangular cross-section multi-pipe junction includes the following steps:

[0028] Step 1: Bending the steel plate 6 into a steel pipe 3, the cross-sectional shape of the steel pipe 3 is an isosceles triangle. The steel pipe 3 and the steel plate 6 have a thickness of 8 mm.

[0029] The steel plate 6 is placed on the bending and forming platform 7 of the frame 4, the steel plate 6 is bent into a steel pipe 3 with an isosceles triangle in cross section by using the forming stamping assembly 5, and the compression plate 14 on the limit compression cylinder 13 is used The steel plate 6 is fixed on the bending forming platform 7, and the bending stamping cylinder 12 at the two ends of the clamping oil cylinder 13 is stretched downward and the bending stamping block 15 performs the bending process on both sides of the steel plate 6. Then, at the welding rail 8 below the bending forming platform...

Abstract

The invention relates to a method for manufacturing a multi-pipe confluence node with an isosceles triangular cross-section, which belongs to the technical field of building steel structures. The operation steps are as follows: the first step: bending and forming a steel plate into a steel pipe, and the cross-sectional shape of the steel pipe is an isosceles triangle . Step 2: Take a solid steel rod at one end and grind both ends of the solid steel rod. Step 3: Take several inserting plates and weld them with solid steel rods in an equal-spaced circular distribution with the solid steel rods as the center. Step 4: Between two adjacent inserting plates, weld the steel pipe to the inserting plate in the opposite-side through-length manner, and finally polish the weld seam to make it smooth. It has the characteristics of simple structure, good stability and long service life. The problem of low stiffness of the connection nodes of the space-fabricated steel structure is solved.

Description

technical field [0001] The invention relates to the technical field of building steel structures, in particular to a method for manufacturing an isosceles triangular cross-section multi-pipe intersection node. Background technique [0002] With the continuous development and application of modern building steel structures, more and more buildings, especially public buildings, are increasingly using single-layer reticulated shell structures. It is a novel structural form with a reasonable force transmission path, high bearing capacity, wide support coverage, and a larger transparent space can be formed with a smaller bar section. The single-layer shell has both beautiful appearance and good lighting function, and has been more and more favored by people in recent years. [0003] The single-layer reticulated shell has become a promising space structure form due to its advantages of reasonable force, economical materials, beautiful and changeable shape, and ability to span a l...
