Spoke type wave-shaped cable membrane structure roof with three-dimensional outer ring truss
The invention discloses a spoke type wave-shaped cable membrane structure roof with a three-dimensional outer ring truss. An upper pressed outer ring, a lower pressed outer ring and a modeling outer convex ring are connected through diagonal web members to form the three-dimensional ring truss; a pulled inner ring cable is connected with the upper pressed outer ring through an upper radial cable, and the pulled inner ring cable is connected with the lower pressed outer ring through a lower radial cable to form the spoke type wave-shaped roof; the three-dimensional ring truss can reduce radial compression deformation of the roof and is attractive in modeling; a closed force transmission path is formed, so that the prestress loss of the upper radial cable and the lower radial cable is reduced; and the whole cable membrane structure roof fully exerts the mechanical efficiency of various materials, and perfect combination of the shape and efficiency is achieved. The structure is good in anti-seismic property and low in self weight and has wide applicability in large public buildings such as stadiums and football fields.
本发明公开一种具有立体外环桁架的轮辐式波形索膜结构屋盖，其上受压外环、下受压外环和造型外凸环分别通过斜腹杆连接，构成立体环桁架；受拉内环索与上受压外环之间通过上径向索连接，受拉内环索与下受压外环之间通过下径向索连接，构成轮辐式波形屋盖，立体环桁架能减小屋盖的径向压缩变形，且造型美观；其形成封闭的传力途径，从而减小上径向索和下径向索的预应力损失；其整个索膜结构屋盖充分发挥了各种材料的力学效能，实现了形状与效率的完美结合。该结构抗震性能好，自重轻，在体育场、足球场等大型公共建筑中具有广泛的适用性。
