Embodiment

[0027] Example: as Figure 1-4 As shown in the figure, the production method of a new node for isosceles triangle cross-section multi-pipe intersection includes the following steps:

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

[0029] The steel plate 6 is placed on the bending and forming platform 7 of the frame 4, and the steel plate 6 is bent into a steel pipe 3 whose cross-sectional shape is an isosceles triangle by the forming and stamping assembly 5, and the pressing plate 14 on the cylinder 13 is pressed by the limit. The steel plate 6 is fixed on the bending forming platform 7 , and the bending punching cylinders 12 at both ends of the limiting and pressing oil cylinder 13 stretch the bending punching block 15 downward to perform the bending process on both sides of the steel plate 6 . Next, at the wel...

Abstract

The invention relates to a manufacturing method of a novel multi-manifold joint with an isosceles triangle-shaped section, and belongs to the technical field of building steel structures. The method comprises the following steps of 1, bending a steel plate into a steel pipe with an isosceles triangle-shaped cross section; 2, taking a solid steel bar at one end, and polishing two end surfaces of the solid steel bar; 3, ensuring that a plurality of inserting plates are taken and annularly distributed at equal intervals with the solid steel bar as the center to be subjected to equal-strength groove welding with the solid steel bar. 4, between every two adjacent inserting plates, welding the steel pipe to the inserting plates in an opposite-side full-length mode, and finally polishing weld joints to be flat. The method has the advantages of simple structure, good stability and long service life. The problem that a space assembly type steel structure connecting joint is low in rigidity is solved.

Description

technical field [0001] The invention relates to the technical field of building steel structures, in particular to a new method for manufacturing an isosceles triangular cross-section multi-pipe intersection. Background technique [0002] With the continuous development and application of modern building steel structures, more and more buildings, especially public buildings, are using single-layer reticulated shell structures more and more closely. 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 favored by more and more people in recent years. [0003] The single-layer reticulated shell has become a promising space structure due to its reasonable force, economical use of materials, beautiful and changeable appearance, and the ability to sp...
