Problems solved by technology

[0003] Twisted box-shaped column is a box-shaped steel member with torsion and bending shape. It is composed of four twisted and twisted plates connected in sequence. In order to improve the structural strength of twisted box-shaped column, intervals are often set inside it. It is difficult to process this kind of twisted box-shaped column, especially when splicing four twisted plates, it takes a lot of labor and a lot of man-hours, and it is easy to cause welding errors between the bent and twisted plates Causes twisting and bending deviations in twisted box columns

Embodiment 1

[0045] Such as figure 1 and figure 2 As shown, this embodiment provides a method for manufacturing a twisted box-shaped column, which includes the following steps:

[0046] According to the design drawings, open the sample and typesetting the steel plate. During the typesetting, the cutting is carried out in sections according to the length and width of the steel plate. When cutting 1 meter, a shrinkage of 0.3mm is reserved, and then the numerical control is arranged and edited, and the typesetting program is exported and imported into Plasma cutting machine, on the plasma cutting machine, the material is accurately cut according to the programming. Before cutting, the plate is leveled with a leveler to ensure that the parts are cut accurately and cut, and a plate with a length of 11m and a width of 20mm is obtained.

[0047] Transport the boards obtained by segmental cutting to the assembly workshop, and make bevels on them. The beveling will cause the side bends of the boa...

Embodiment 2

[0056] Such as figure 1 and image 3 As shown, the embodiment of the present application provides a manufacturing method of a twisted box-shaped column, which is roughly the same as the manufacturing method of a twisted box-shaped column provided in Example 1. The difference is that in this embodiment, according to the design drawings When calculating the torsion angle of the twisted box-shaped column on the relative contour line from the top view and relative contour drawings, the spatial coordinates of the four connection points 700 connecting the twisted box-shaped column to each tire frame 600 are calculated respectively, The X-axis, Y-axis and Z-axis data of the four connection points 700 are obtained, and two of the connection points 700 are located on the first torsion plate 200 forming the bottom wall of the torsion box column, and the two connection points 700 are located on the On the second twisted torsion plate 300 of the side wall of the twist box type column; ac...

Abstract

The invention relates to the technical field of steel component manufacturing, in particular to a bending-torsion box type column manufacturing method. The bending-torsion box type column manufacturing method comprises the following steps of cutting steel plates into plates in a segmented mode; bending and splicing the plates to obtain a first bending plate, a second bending plate, a third bendingplate and a fourth bending plate correspondingly; correspondingly calculating three-dimensional space coordinates of at least three connecting points of the bending-torsion box type column and each jig frame according to the drawing, and correspondingly preparing the jig frame according to the three-dimensional space coordinates of at least three connecting points of the obtained jig frame and fixing; corresponding the torsion angle and the position of the jig frame to the torsion angle and position of the cross section of the bending-torsion box type column supported by the jig frame; and fixing the first bending plate on each jig frame, and sequentially fixing the second bending plate, each partition, the third bending plate and the fourth bending plate on the first bending plate. According to the bending-torsion box type column manufacturing method, the construction difficulty of the bending-torsion type box type column can be reduced, and the quality can be improved.

Description

technical field [0001] The application relates to the field of steel component manufacturing, in particular, to a method for manufacturing a twisted box-shaped column. Background technique [0002] With the rapid development of construction engineering, many ultra-long-span structures and architectural shapes have appeared. Under the requirements of both practicality and aesthetics, some components in the structure need to be twisted and bent due to the aesthetic requirements. of various shapes. [0003] The twisted box-shaped column is a box-shaped steel member with torsion and bending shape. It is composed of four twisted and twisted plates connected and enclosed in turn. In order to improve the structural strength of the twisted box-shaped column, intervals are often set inside it. It is difficult to process this kind of twisted box-shaped column, especially when splicing four twisted plates, it takes a lot of labor and a lot of man-hours, and it is easy to cause welding...
