Construction method of large-span corridor arch rib and construction method of large-span corridor
The invention relates to the technical field of building corridor construction, in particular to a construction method of a large-span corridor arch rib and a construction method of a large-span corridor. According to the construction method of the large-span corridor arch rib, temporary inhaul cables are tensioned by fully utilizing the strength and rigidity of support cylinders on the two sides of a corridor, and the construction efficiency of the large-span corridor arch rib is improved; the single-section arch rib can be stably connected to the arch springing through the temporary inhaul cable, it is avoided that due to the fact that the single-section arch rib and the arch springing are not stably connected, the arch rib is difficult to install, and the installation period of a large-span corridor is affected, further, splicing of the single-section arch rib is achieved through the temporary inhaul cable, the construction installation operation of the arch rib is completed, and the construction process of firstly arching and then beam is achieved; therefore, when the follow-up large-span corridor is installed, a cast-in-place support or jig frame does not need to be erected at the bottom of the corridor, the construction period is effectively shortened, use of a steel structure is reduced, the purpose of saving cost is achieved, meanwhile, the influence of ground channel foundation deformation on the corridor structure is reduced, and interference on a ground channel during corridor construction is reduced.
本发明涉及一种建筑连廊施工技术领域，特别涉及一种大跨径连廊拱肋的施工方法及大跨径连廊的施工方法，本发明所述的一种大跨径连廊拱肋的施工方法，充分利用连廊两侧支座筒体的强度和刚度来张拉临时拉索，通过临时拉索使单节拱肋能稳固的连接在拱脚上，避免单节拱肋与拱脚连接不稳定而导致拱肋安装困难，影响大跨径连廊的安装工期，进一步地，通临时拉索来实现对单节拱肋的拼装，以完成拱肋的施工安装作业，达到先拱后梁的施工工艺，进而使后续大跨径连廊安装时，无需在连廊底部搭设现浇支架或胎架，有效节约工期，减少钢结构的使用，达到节省成本的目的，同时减少地面通道地基变形对连廊结构的影响，降低连廊施工时对地面通道的干扰。
