[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

Embodiment
[0117] Such as Figure 1-Figure 3 The complex bending and torsion member of an annular canopy shown is composed of the canopy bending and torsion member 1 and the secondary rib member 2. Two sets of roof bending and torsion members are placed side by side, and the two ends of the secondary rib member are respectively connected to a group of roof bending and torsion members. Rods connect two groups of roof bending and torsion rods into a whole.
[0118]The canopy bending and twisting member 1 is composed of a main rib body 11, a secondary rib corbel connector 12, a curtain wall rod connector 15, a curtain wall rod 13, a secondary rib corbel 14 and a box-shaped corbel 16; the main rib body 11 is a curved Twisted box-shaped, with a trapezoidal cross-section; the secondary rib corbel connector 12 and the curtain wall rod connector 15 are box-shaped; the curtain wall rod 13 is a ladder-shaped tube structure composed of twisted round tubes; the secondary rib corbel 14 is A twisted ...

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...
