Problems solved by technology

In addition, because the wall thickness of the box body varies greatly from 16mm to 115mm, but the distortion is very large, and the processing and welding deformation is difficult to control, so the processing and production is very difficult. It is necessary to focus on the analysis of special components and formulate corresponding feasible solutions. Processing technology to ensure its production accuracy requirements

Abstract

The invention relates to a twisting box-shaped member and a manufacture process thereof and belongs to the technical field of steel structures. The twisting box-shaped member comprises a top plate, a base plate and a rectangular box, wherein the rectangular box is enclosed by webs, and the cross section of the rectangular box is an isosceles trapezoid. More than one cross partition plate is arranged on the rectangular box. The twisting box-shaped member is large in twisting range, reasonable in design and firm in structure.

Description

technical field [0001] The invention relates to a bent-torsion box-shaped member and a manufacturing process thereof, and belongs to the technical field of steel structures. Background technique [0002] With the rapid development of construction engineering, many super-long-span structures and many new architectural shapes have appeared. These structures and shapes are very complicated. In order to make the structure meet the requirements of architectural shapes, some components in the structure need to change with the curvature of the structure. And changes, these changes include bending, torsion and abnormal shape of components. The concrete structure cannot achieve these shapes alone due to its own weight and later bearing capacity. Phoenix International Media Center is a steel structure building project located in Chaoyang Park, Beijing. It is a new concept. The media experience cabin, which surpasses the previous relationship between the media and the audience through ...
