Embodiment 1

[0084] The invention provides a method for processing a M-shaped box-shaped steel structure node, comprising the following steps:

[0085] a: Install support rods to form a tire frame; in this embodiment, draw a projection line corresponding to the deepening dot pattern on the horizontal platform according to the deepening dot pattern, and then mark several sample punches according to the projection line eye, and finally place support rods at all the punch holes to set up the tire frame, which is used to place the lower wing plate 1;

[0086] b: Bending the upper wing plate 2 and the lower wing plate 1 respectively; in this embodiment, in order to meet the space modeling requirements of the special-shaped curved surface of the steel structure roof, the ports of the steel members all have torsion sections, so the M-shaped box The steel structure node also needs to correspond to the bending angle of the steel structure, and the bending angle refers to the bending angle, so the l...

Embodiment 2

[0097] This embodiment provides a method for processing a M-shaped box-shaped steel structure node, which is different from Embodiment 1 in that the steps c-f can be replaced by the following steps as a whole:

[0098] c': Weld all the first inner partitions 13, the first web 11 close to the third main frame 7, and the third middle plate 331 on the lower wing 1 respectively, and then The upper wing plate 2 is welded to the top of all the installed first inner partitions 13, the first web 11 close to the third main frame 7, and the third middle plate 331. end face;

[0099] d': welding all the third webs 31 and all the first sealing plates 12;

[0100] e': welding the first web 11 close to the second main frame 6;

[0101] f': Weld the second middle plate 231, and then weld all the second webs 21.

[0102] The size of the second main frame 6 and the third main frame 7 of the M-shaped box-shaped steel structure node can be selected according to the construction requirements. ...

Embodiment 3

[0104] This embodiment provides a processing method for a P-shaped box-shaped steel structure node, which is consistent with Embodiment 1 as a whole, and is a detailed step of the processing method for a P-shaped box-shaped steel structure node described in Embodiment 1, including the following step:

[0105] a: Install support rods to form a tire frame; in this embodiment, draw a projection line corresponding to the deepening dot pattern on the horizontal platform according to the deepening dot pattern, and then mark several sample punches according to the projection line eye, and finally place support rods at all the punch holes to set up a tire frame, and the tire frame is used to place the lower wing plate 1;

[0106] b: Bending the upper wing plate 2 and the lower wing plate 1 respectively. In this embodiment, in order to meet the space modeling requirements of the special-shaped curved surface of the steel structure roof, the ports of the steel members all have torsion s...

Abstract

The present invention relates to the technical field of steel structure processing, in particular to a method for processing a M-shaped box-shaped steel structure node. The overall structure of the M-shaped box-shaped steel structure node is finalized by five of the plate and the second middle plate, and the overall frame of the M-shaped box-shaped steel structure node is determined, which can reduce the impact of welding on the upper wing plate and the lower flange. The bending accuracy of the wing plate is changed, and at the same time, adopting a reasonable welding sequence can facilitate the welding of the internal welds of the first main frame, the second main frame, and the third main frame, improve the quality of the welds, and meet the requirements of the above-mentioned requirements. While the integrity of the zigzag box-shaped steel structure joints is good, the weld processing in the narrow internal space can be realized smoothly, which ensures the quality of the welds between the plates and improves the quality of the m-shaped box-shaped steel structure joints.

Description

technical field [0001] The invention relates to the technical field of steel structure processing, in particular to a processing method for a rice-shaped box-shaped steel structure node. Background technique [0002] With the pursuit of complex and diverse architectural shapes in modern society, the steel reticulated shell structure has been more and more widely used in the current construction field due to its novel shape, light weight, convenient construction, and reasonable force system. However, due to the changeable shape of the reticulated shell structure of the steel structure, its structural form is complex, so it is easy to form the intersection nodes of longitudinal beams, beams, and oblique beams, such as T-shaped, cross-shaped, and rice-shaped, among which the rice-shaped nodes The structure is the most complex and the processing difficulty is the greatest. [0003] The node structure of the M-shaped box-shaped steel structure in this technology is as follows: ...
