Construction method of large-span hangar
The invention discloses a construction method of a large-span hangar. The construction method comprises the steps that a plurality of steel structure units are spliced into a steel structure integral lifting unit, and a lifting platform is arranged; a hydraulic synchronous lifting system is installed and debugged; the steel structure integral lifting unit is lifted to a first height to suspend lifting, and continues to be lifted to a second height to suspend lifting so as to install a gate truss and a net rack butt joint rod; the steel structure integral lifting unit is lifted to a third height which is a preset distance away from the installation elevation to suspend lifting; the lifting speed of the steel structure integral lifting unit is reduced, and all lifting points are finely adjusted, so that the steel structure integral lifting unit reaches the design position; and rod pieces are additionally installed between the steel structure integral lifting unit and a steel structure supporting frame and between the steel structure integral lifting unit and another steel structure integral lifting unit. According to the construction method of the large-span hangar, the technical problems that in an existing hangar construction method, the construction difficulty is large, and control over the safety, quality and construction period of steel structure field installation is not facilitated can be solved.
本发明公开了一种大跨度机库的施工方法，包括：将若干钢结构单元拼装成一钢结构整体提升单元并设置提升平台；安装液压同步提升系统并调试；将钢结构整体提升单元提升第一高度暂停提升，并继续提升至第二高度暂停提升以安装大门桁架与网架对接杆；将钢结构整体提升单元提升至距离安装标高一预设距离的第三高度暂停提升；降低钢结构整体提升单元的提升速度，对各个吊点微调，使钢结构整体提升单元到达设计位置；在钢结构整体提升单元与钢结构支撑架之间，以及钢结构整体提升单元与另一钢结构整体提升单元之间补装杆件。本发明能够解决现有机库施工方法中施工难度大，不利于钢结构现场安装的安全、质量以及工期的控制的技术问题。
