Construction method for integrally lifting large-span vehicle amplitude type single-double layer mixed cable net
The invention discloses a construction method for integrally lifting a large-span vehicle amplitude type single-double layer mixed cable net. Comprising the following steps: manufacturing a structural lug plate on an external pressure ring steel structure, building a jig frame, presetting a circumferential cable clamp, mounting a steel structure hanging basket and lifting and tensioning auxiliary equipment, monitoring deformation, pulling, sequentially lifting a cable net at the junction of a single-layer cable net and a double-layer cable net in place and anchoring the cable net with the structural lug plate, and integrally lifting and tensioning the cable net through a radial cable on the double-layer cable net. And adjusting the lengths of the radial cables under the double-layer cable net and the radial cables of the single-layer cable net to change the spatial form of the cable structure. According to the construction method, by selecting a staged integral oblique traction single-layer and double-layer mixed cable net construction method, installation and prestress tensioning of the spoke type single-layer and double-layer mixed cable net are smoothly completed, a unique spoke type single-layer and double-layer mixed cable net space structure form is obtained, the whole construction process is relatively simple and convenient, the construction efficiency is high, and the construction cost is low. And the stability and the safety of each node and each link are relatively high.
本发明公开一种大跨度车幅式单‑双层混合索网整体提升的施工方法，包括在外压环钢结构上制作结构耳板、搭建胎架、预设环向索索夹、安装钢结构挂篮和提升及张拉辅助设备、变形监控、牵引、依次进行单双层索网交界处索网提升就位并与结构耳板锚接、索网整体提升张拉完成后通过对双层索网上径向索、双层索网下径向索和单层索网径向索长度的调整来改变索结构的空间形态等施工步骤。本施工方法通过选择分阶段整体斜向牵引的单双层混合索网施工方法，顺利地完成了车辐式单‑双层混合索网的安装与预应力张拉，得到了独特的车幅式单‑双层混合索网空间结构形态，整个施工过程相对简便，施工效率较高，而且各节点和各环节的稳定性和安全性较高。
