Fabricated large-span arch crown structure of subway station and construction method
The invention discloses a subway station assembly type large-span vault structure, and relates to the technical field of building construction. A plurality of sets of prefabricated parts are sequentially arranged in the length direction of the subway station, each set of prefabricated parts is of an integrated structure formed by arch-shaped beam supporting and steel chord member prefabrication, the two ends of each prefabricated part are in lap joint with a diaphragm wall, and the prefabricated parts and the diaphragm wall are connected through fixing parts. The prefabricated plates are erected between every two adjacent prefabricated parts, the prefabricated arched beam supports and the steel chord members serve as prefabricated vaults and are erected on an underground diaphragm wall to form a first support, the prefabricated plates are hoisted and erected on the prefabricated arched beam supports in the main body back-building stage, and concrete is cast in place to form the vaults after steel bar lap joint is completed. After construction is completed, waterproof treatment needs to be conducted on the arch crown structure, finally, soil is backfilled, and the arch crown structure built in the mode has the advantages of being short in period, low in cost and good in waterproofness.
本发明公开了一种地铁车站装配式大跨拱顶结构，涉及建筑施工技术领域，包括预制构件和预制板；所述预制构件沿着地铁车站的长度方向顺次布设有多组，每组所述预制构件均为由拱形梁支撑及钢弦杆预制形成的一体化结构，所述预制构件的两端搭接在地连墙上，且所述预制构件和所述地连墙之间通过固定部件连接；所述预制板搭设在相邻的两个预制构件之间，所述预制拱形梁支撑及钢弦杆为预制拱顶，搭设在地连墙形成第一道支撑，主体回筑阶段将预制板吊装搭设在预制拱形梁支撑，完成钢筋搭接后，再现浇混凝土形成拱顶，施工完成后需要对拱顶结构做防水处理，最后回填覆土，通过该方式搭建的拱顶结构具有周期短、成本低、防水性好特点。
