Complex annular shed bending and twisting component and manufacturing method thereof

Abstract

The invention discloses a complex annular shed bending and twisting component. The complex annular shed bending and twisting component comprises shed bending and twisting members and secondary rib rod pieces, wherein each shed bending and twisting member comprises a main rib body, secondary rib corbel connecting pieces, curtain wall rod piece connecting pieces, curtain wall rod pieces, secondary rib corbels, a box-shaped corbel and the like; the curtain wall rod piece connecting pieces, the secondary rib corbel connecting pieces, the secondary rib corbels, the curtain wall rod pieces and the box-shaped corbel are welded on the body side of the main rib body; the curtain wall rod pieces are welded on the curtain wall rod piece connecting pieces; the secondary rib corbels are welded on the secondary rib corbel connecting pieces; and the secondary rib rod pieces are connected with the secondary rib corbels to connect the two groups of shed bending and twisting members together. The invention also discloses a manufacturing method for the complex annular shed bending and twisting component. A roof space steel structure body and the manufacturing method thereof provided by the invention solve the problems that a beam of the roof shed has a long main rib and a big camber and is difficult to process; and the whole roof shed is divided into a plurality of roof space steel structure bodies so as to increase the construction speed, shorten the construction time and reduce the construction difficulty.

Description

technical field [0001] The invention relates to a steel component, in particular to a complex bending and torsion assembly of an annular canopy. Background technique [0002] The steel structure of the Phoenix Satellite TV Media Center is a super-long-span space structure. The steel structure roof is composed of a two-way cross double full-beam structure and a vertical support system. It is about 130m long and 124m wide. The trapezoidal grid is formed, and the components have the characteristics of spatial bending and twisting in different degrees. The outer surface of the steel structure of the Phoenix Satellite TV Media Center is a free-form surface. The overall steel structure is used to cover the office building and the studio building. The overall steel structure is a two-way cross double full-beam structure system. The steel beam of the first floor (lower floor) is a circular steel pipe section. Part of the steel structure of the office building is attached to the c...

[0011] 3. Component plate thickness

[0012] The thickness of the bending and torsion members of the National Stadium is 20-80mm, and the thickness of the bending and torsion ribbons of the Kunming Airport is 25-90mm. The maximum thickness of the bending and torsion main ribs of this project is 115m, and the minimum is only 16mm. Due to the complicated structural stress, Frequent alternation of thick and thin plates brings unprecedented processing difficulty to plate processing and component manufacturing
