Method for constructing subway supporting beam
The invention discloses a method for constructing a subway supporting beam. The method comprises the following steps that multiple prefabricated supporting devices are manufactured; a scaffold is constructed between two adjacent continuous walls, so that the top end of the scaffold is flush with the top ends of the continuous walls; crown beam reinforcement cages are arranged at the tops of the continuous walls, and a middle longitudinal beam reinforcement cage is arranged in the middle of the scaffold; the prefabricated supporting devices are hung between the middle longitudinal beam reinforcement cage and the crown beam reinforcement cages; formworks are supported around the crown beam reinforcement cages and around the clearance between the crown beam reinforcement cages and the prefabricated supporting devices; and concrete is poured, so that the concrete covers the crown beam reinforcement cages and the middle longitudinal beam reinforcement cage. In the construction process, thesupporting beam structure can be built faster through the method, and compared with a cast-in-place construction method, more construction procedures can be saved, more labor cost can be reduced, andthe construction progress is greatly accelerated.
本发明公开了一种地铁支撑梁的施工方法，包括以下步骤：制作多个预制支撑装置；在相邻两连续墙之间搭建脚手架，以使所述脚手架顶端与所述连续墙顶端相互平齐；各所述连续墙的顶部均设置冠梁钢筋笼，所述脚手架中部设置中纵梁钢筋笼；所述中纵梁钢筋笼与各所述冠梁钢筋笼之间吊装所述预制支撑装置；在所述冠梁钢筋笼周围以及所述冠梁钢筋笼和所述预制支撑装置之间的间隙周围支支撑模板；浇筑混凝土，以使混凝土覆盖所述冠梁钢筋笼和所述中纵梁钢筋笼。在施工过程中，通过这种方法能够更为快捷的修筑支撑梁结构，相比现浇式的施工方法，能够节省更多的施工工序和人力成本，大大加快施工进度。
