Rapid installation and construction method for large-span steel truss framework membrane structure
The invention discloses a rapid installation and construction method for a large-span steel truss framework membrane structure. The technical problems that an existing all-round scaffold is low in construction speed, large in occupied construction site, high in construction cost, low in membrane tensioning construction efficiency and low in construction precision are solved. The method comprises the steps of large-span steel truss framework construction and membrane structure construction, wherein the large-span steel truss framework is assembled in a segmented mode and then hoisted in a segmented mode to form the large-span steel truss framework; the technical problems that an all-round scaffold is high in construction cost, low in construction speed and large in occupied construction site can be effectively solved by adopting the assembly type supports at the segmented positions, and the construction progress can be effectively guaranteed; construction finite element simulation is carried out before construction, so that manufacturing and mounting pre-deformation control can be effectively guaranteed to improve the construction precision. And the membrane structure is tensioned and fixed through a membrane structure rapid tensioning tool, four fastening points are tensioned at the same time at a time so that the tensioning construction efficiency can be effectively improved, the tensioning expansion amount can be conveniently controlled and measured, and the tensioning precision can be effectively guaranteed.
本发明公开了一种大跨度钢桁架骨架膜结构快速安装施工方法，解决目前满堂脚手架施工速度慢、施工场地占用多、施工费用高、膜材张拉施工效率低、施工精度不高的技术问题。本发明方法包括大跨度钢桁架骨架施工和膜结构施工，前者对大跨度钢桁架骨架进行分段组装后分段吊装以形成大跨度钢桁架骨架；分段位置采用装配式支架可有效解决满堂脚手架施工费用高、施工速度慢、占用施工场地多的技术问题，能有效保证施工进度；施工前开展施工有限元模拟可有效保证制造和安装预变形控制以提高施工精度。后者对膜结构采用膜结构快速张拉工装进行张拉固定，一次性同时张拉四个紧固点以有效提高张拉施工效率且张拉伸缩量便于控制和测量，可有效保证张拉精度。
