Inhaul cable prestressed giant grid canopy structure
The invention discloses an inhaul cable prestressed giant grid canopy structure. The inhaul cable prestressed giant grid canopy structure comprises an annular upper giant reticulated shell structure,upper crossed cable supporting systems and a lower prestressed cable rod system; the upper giant reticulated shell structure comprises a plurality of three-dimensional truss rings which are coaxiallyarranged, the three-dimensional truss rings are connected through radial three-dimensional trusses, main joint areas are formed at the joints of the three-dimensional truss rings and the radial three-dimensional trusses, and the radial three-dimensional trusses are annularly and uniformly arranged along the three-dimensional truss rings in an even number; the three-dimensional truss rings and theradial three-dimensional trusses form large grids, and upper crossed cable supporting systems are arranged in the plurality of mutually-symmetrical large grids; and the lower prestressed cable rod system is arranged below the upper giant reticulated shell structure. The inhaul cable prestressed giant grid canopy structure overcomes the defects that in a full-tension structure system, the structural rigidity mainly depends on tension of a prestress system, and the tension construction precision requirement is high, and obviously reduces the construction difficulty; and the inhaul cable prestressed giant grid canopy structure meets diversified building modeling requirements and can be widely applied to non-closed buildings such as stadiums and football fields.
本发明公开了一种拉索预应力巨型网格罩篷结构，包括环形的上部巨型网壳结构、上部交叉索撑体系和下部预应力索杆体系；所述上部巨型网壳结构包括若干同轴设置的立体桁架环，立体桁架环通过径向立体桁架连接，且与径向立体桁架连接处形成主节点区，径向立体桁架沿立体桁架环环向均匀布置且数量为偶数；立体桁架环与径向立体桁架形成大网格；若干相互对称的大网格内布置有上部交叉索撑体系；上部巨型网壳结构下方安装有下部预应力索杆体系。本发明克服了全张拉结构体系中结构刚度主要依赖于预应力体系的张拉、张拉施工精度要求高的缺陷，明显降低施工难度；壳满足多样化的建筑造型需求且可广泛应用于体育场、足球场等非封闭建筑。
