Curved dual-layer latticed shell structure gradual expansion assembly jacking construction method
The invention discloses a curved dual-layer latticed shell structure gradual expansion assembly jacking construction method. The curved dual-layer latticed shell structure gradual expansion assembly jacking construction method comprises the following steps of mounting of a lower conversion layer; mounting of a starting segment jacking frame; mounting of a starting unit latticed shell; jacking to asecond-stage height, mounting of a second-stage jacking frame and an upper portion conversion joint, and dismounting of a first-stage jacking frame; jacking to a third-stage height, and at differentelevation stands, mounting of a third-stage ladder jacking frame, and the upper conversion joint, and meanwhile, mounting of a latticed shell on a jacking platform; jacking to the design elevation; folding; and whole unloading. Through the method, the problem of construction of a curved latticed shell in a venue with a basement and different elevation stands can be solved, a large amount of temporary measures of erecting all-round scaffolds can be avoided, the construction speed is improved, cost is saved, and construction quality is effectively ensured.
本发明公开了一种曲面双层网壳结构渐扩拼装顶升施工方法，包括步骤：安装下部转换层；安装起步段顶升架；安装起步单元网壳；顶升至第二阶段高度，安装第二阶段顶升架及上部转换节点，拆除第一阶段顶升架；顶升至第三阶段高度，在不同标高看台上安装第三阶段阶顶升架及上部转换节点，同时安装顶升平台上网壳；顶升至设计标高；合拢；整体卸载。采用此方法解决了曲面网壳在有地下室及不同标高看台的场馆内施工的问题，避免了搭设满堂脚手架等大量临时措施，提高了施工速度，节约了成本。有效保证施工质量。
