Anti-instability device for large-span beam string structure construction
The anti-instability device comprises an upper truss, a vertical clamp and a lateral support, the upper truss is a steel truss and comprises chord members, diagonal web members and straight web members, the chord members are divided into upper chord members and lower chord members, the straight web members are vertically connected between the upper chord members and the lower chord members, and the diagonal web members are connected between the upper chord members and the lower chord members. The two ends of the diagonal web members are respectively connected to the connecting points between the straight web members and the upper chord and the lower chord; one end of the vertical clamp and one end of the lateral support are respectively connected with the straight web member, and the other end of the vertical clamp is connected with the other end of the lateral support. In the installation process of the beam string structure, a temporary support does not need to be erected, measure materials and labor input are saved, the construction period is shortened, cost is reduced, meanwhile, safety risks caused by high-altitude operation are avoided, and the anti-instability device has the anti-deformation function in the tensioning and hoisting process of the beam string structure and has the advantages of being fast to assemble, easy to operate, detachable, safe, reliable and the like. And economy and practicability are realized.
本发明公开一种用于大跨度张弦梁施工的防失稳装置，包括上部桁架、竖向夹具和侧向支撑，所述上弦桁架型钢桁架，包含弦杆、斜腹杆、直腹杆，所述弦杆分为上弦杆和下弦杆，直腹杆垂直连接在上弦杆和下弦杆之间，斜腹杆两端分别连接在直腹杆与上弦杆和下弦杆之间连接点处；所述竖向夹具的一端和侧向支撑的一端分别与直腹杆连接，竖向夹具的另外一端和侧向支撑的另外一端相连接。本发明在张弦梁安装过程中，不需要搭设临时支架，节省措施材料和人工投入，缩短了工期，减少了成本，同时避免高空作业带来的安全风险，防失稳装置在张弦梁张拉和吊装过程中具有防变形功能，具有组装快、操作简单、可拆卸，安全可靠，经济实用的特点。
