Super-large-span heavy-load prestressed space truss based on topological optimization principle
The invention relates to a super-large-span heavy-load prestressed space truss based on the topological optimization principle. The super-large-span heavy-load prestressed space truss comprises a truss body, arc-shaped inhaul cables and vertical supports. The super-large-span heavy-load prestressed space truss is characterized in that the truss body is an arch bridge-shaped three-dimensional truss, and the arch bridge-shaped three-dimensional truss comprises an upper chord member, an arch-shaped lower chord member and a truss web member; the arc-shaped inhaul cable is divided into a first arc-shaped inhaul cable and a second arc-shaped inhaul cable; the vertical supports adopt a V-shaped support and a U-shaped support; the contact area of the first arc-shaped inhaul cable and the second arc-shaped inhaul cable is hinged to the truss arch-shaped lower chord through the V-shaped support, and the separation area of the first arc-shaped inhaul cable and the second arc-shaped inhaul cable is hinged to the truss arch-shaped lower chord through the U-shaped support; and the end part of the first arc-shaped inhaul cable and the end part of the second arc-shaped inhaul cable are connected with a joint plate on the truss through lug plates and pin shafts, the lug plates are connected with the inhaul cables through cable heads, and the joint plate and the truss are welded in an inserted mode.
本发明涉及一种基于拓扑优化原理的超大跨重载预应力空间桁架，包括桁架、弧形拉索和竖向支撑，其特征在于：桁架为拱桥形立体桁架，拱桥形立体桁架包括上弦杆、拱形下弦杆和桁架腹杆；弧形拉索分为第一弧形拉索和第二弧形拉索；竖向支撑采用V形支撑和U形支撑；第一弧形拉索和第二弧形拉索接触区域采用V型支撑与所述桁架拱形下弦铰接连接,第一弧形拉索和第二弧形拉索分离区域采用U形支撑与所述桁架拱形下弦铰接连接；第一弧形拉索、第二弧形拉索的端部通过耳板、销轴与桁架上的节点板连接，耳板通过索头与拉索连接，所述节点板与桁架采用插入式焊接。
