Structure construction quick-dismantling method for subway station by utilizing middle plate stress
The invention discloses a structure construction quick-dismantling method for a subway station by utilizing middle plate stress. Platform layer frame bodies are mainly utilized for span-by-span erection and staged dismantling, the middle plate stress span is reduced to reduce the form dismantling strength, meanwhile, station hall layer top plate construction is achieved by utilizing the middle plate bearing capacity, a station construction quick-dismantling system is formed, and the station hall layer frame bodies can also be subjected to span-by-span erection and staged dismantling, so that the turnover rate of formwork frame bodies is increased, the investment is reduced, and the cost is reduced. The structure construction quick-dismantling method is mainly achieved through the following six steps that 1, a subway platform layer bottom plate and platform layer side walls are constructed; 2, a platform layer mid-span beam plate formwork support and a platform layer side span formwork support are erected and bound through steel bars; 3, platform layer middle plate concrete pouring and curing are conducted; 4, station hall layer structure side walls are constructed; 5, a station hall layer top plate mid-span beam plate formwork support and a station hall layer top plate side span formwork support are erected and bound through steel bars; and 6, station hall layer top plate concrete pouring and curing are conducted. In the steps, the station hall layer formwork supports can also be subjected to span-by-span erection and staged dismantling, so that the purpose of quick dismantling of the top plate formwork support part is achieved, and the investment of the formwork supports is further reduced.
本发明公开了一种地铁车站利用中板受力的结构施工快拆方法，主要利用站台层架体分跨搭设和分阶段拆除，减小中板受力跨度来降低拆模强度，同时利用中板承载力实现站厅层顶板施工，形成车站施工快拆体系，站厅层架体同样可以分跨搭设和分阶段拆除，以提高模板架体周转率，减少投入，节约成本，本发明的实现主要包括以下六步：第一步：将地铁站台层底板、站台层侧墙施工，第二步，站台层跨中梁板模板支架及站台层边跨模板支架搭设、钢筋绑扎；第三步，站台层中板混凝土浇筑及养护；第四步，站厅层结构侧墙施工，第五步，站厅层顶板跨中梁板模板支架及站厅层顶板边跨模板支架搭设、钢筋绑扎；第六步，站厅层顶板混凝土浇筑、养护，此步骤中站厅层模板支架也可分跨搭设、分阶段拆除，以实现顶板模板支架部分快拆的目的，进一步节省模板支架的投入。
