Segmented lifting method for asymmetric large-span cantilever steel structure corridor
The method comprises the following steps that the asymmetric large-span cantilever steel structure corridor is divided into a cantilever section steel structure corridor and a non-cantilever section steel structure corridor, and control lines such as the longitudinal axis and the transverse axis of the two sections of steel structure corridors are released through a measuring instrument; correcting the positions of upper and lower lifting points; jig frame arrangement and assembly of the cantilever section steel structure corridor and the non-cantilever section steel structure corridor are carried out on a floor/roof, main components are remeasured after assembly is completed, and it is ensured that the installation precision is improved; according to the construction method, the steel structure corridor is installed in a regional and staged mode through a limited site, the requirement for parallel construction is met, the construction site is effectively saved, the construction time is shortened, the construction efficiency is improved, the construction cost is reduced, and the construction efficiency is improved. And the total construction cost and the total construction period of the project are favorably controlled.
本发明公开了一种非对称大跨度悬挑钢结构连廊分段提升的方法，包括如下步骤：将非对称大跨度悬挑钢结构连廊分为悬挑段钢结构连廊和非悬挑段钢结构连廊，使用测量仪器放出两段钢结构连廊的纵横轴等控制线，校对上下吊点的位置；在楼面/屋面上进行悬挑段钢结构连廊和非悬挑段钢结构连廊的胎架布置及拼装，拼装完成后对主要构件进行复测，确保提升安装精度；第一次提升悬挑段钢结构连廊，第二次提升非悬挑段钢结构连廊后两段钢结构连廊对接合龙，本发明利用有限场地分区域分阶段进行钢结构连廊安装，满足平行施工的需求，有效节约施工场地、缩短施工时间，对工程的总造价、总工期控制有利。
