Large-span pipe truss temporary support unloading construction method
The invention relates to the technical field of pipe truss unloading, in particular to a large-span pipe truss temporary support unloading construction method which comprises the steps of construction preparation, working platform erection, temporary support erection, pipe truss hoisting, coordinate rechecking, correction, temporary support jacking, inspection before unloading, gradual unloading, deflection change measurement and unloading completion. According to the method, the temporary supporting frame is erected on the standard tower crane section to replace a traditional latticed column for unloading, so that the construction difficulty is reduced while the temporary supporting operation area is increased, the unloading safety of the large-span pipe truss is guaranteed, the labor efficiency is improved, and the construction cost is effectively reduced.
本发明涉及管桁架卸载技术领域，特别是涉及一种大跨度管桁架临时支撑卸载施工方法，按照施工准备，搭设工作平台，搭设临时支撑，管桁架吊装，坐标复核、校正，临时支撑支顶，卸载前检查，逐步卸载并测量挠度变化，卸载完成进行。本发明通过标准塔吊节上搭设临时支撑架代替传统格构柱进行卸载，增大了临时支撑作业面积的同时，降低了施工难度，保证了大跨度管桁架的卸载安全，提高了劳动效率，有效解决了施工成本。
