Beam-slab-column joint of reverse assembly subway station, auxiliary device and construction method
The invention discloses a beam-slab-column joint of a reverse assembly subway station, an auxiliary device and a construction method, and the beam-slab-column joint comprises a prefabricated middle column which is provided with a vertically arranged column body and a column tip located at the bottom of the column body; the beam end lap joint ribs are sequentially arranged from top to bottom along the height of the column body; the multiple brackets are arranged on the column body and located below the multiple beam end lap joint ribs except the bottom; the column pier is located above the beam end lap joint rib at the bottom end of the column body; precast beams are symmetrically mounted on the two sides of the multiple beam end lap joint ribs correspondingly. The prefabricated floor slabs are symmetrically installed on the two sides of the prefabricated beams except the bottom. The bottom plate is located at the bottom of the column body and located below the two precast beams at the bottom; according to the solution that effective connection of beam columns is difficult to achieve for the beam-slab-column joint of the cover-excavation top-down subway station in the prior art, meanwhile, the prefabrication rate of components adopted by the novel joint is high, the size of cast-in-place concrete can be reduced, and the site construction period is shortened.
本发明公开了逆作装配地铁站的梁板柱节点、辅助装置以及施工方法，包括预制中柱，其具有竖向设置的柱身和位于柱身底部的柱尖；多个梁端搭接筋，其沿柱身高度上下依次布置；多个牛腿，其设置于柱身上，且位于除底部外的多个梁端搭接筋的下方处；柱墩，其位于柱身底端的梁端搭接筋的上方；多个所述梁端搭接筋的两侧分别对称安装有预制梁；除底部外的多个预制梁的两侧分别对称安装有预制楼板；以及底板，其位于柱身的底部，且位于底部的两个预制梁的下方；本发明针对现有技术中盖挖逆作地铁车站的梁板柱节点难以实现梁柱有效连接的解决方案，同时该新型节点所采用构件预制率较高，能减少现浇混凝土体积，节省现场施工工期。
