Metro station top plate upturning beam and structure and construction method of node of metro station top plate upturning beam
The invention relates to the technical field of rail transit underground engineering construction, in particular to a subway station top plate upturning beam and node structure and construction method.The subway station top plate upturning beam comprises a top plate, a middle column and a longitudinally-arranged upturning beam, and a support part, connected with the middle column, of the upturning beam is a steel reinforced concrete beam internally provided with H-shaped steel in an embedded mode; the midspan part of the upturning beam is a reinforced concrete beam; the steel bars between the steel reinforced concrete beam and the top plate penetrate through webs of the H-shaped steel; the column rib of the middle column penetrates through the steel reinforced concrete beam through the connecting sleeve, the bolt anchor head and the 90-degree hook to be connected with the steel reinforced concrete beam. According to the structure, the anti-bending and anti-shearing bearing capacity of the upturning beam structure is improved, the impermeability of the station structure is improved, the problems of an existing reinforced concrete upturning beam are solved, and the overall performance of the structure is improved.
本发明涉及轨道交通地下工程建设技术领域，尤其涉及一种地铁车站顶板上翻梁及其节点的构造与施工方法，包括顶板、中柱和纵向设置的上翻梁，所述上翻梁与中柱连接的支座部分为内部埋设有H型钢的型钢混凝土梁，上翻梁的跨中部分为钢筋混凝土梁；所述型钢混凝土梁与顶板之间的钢筋贯通H型钢的腹板；所述中柱的柱筋经连接套筒、螺栓锚头以及90°弯钩贯通穿过型钢混凝土梁与型钢混凝土梁实现连接。该构造提高了上翻梁结构的抗弯、抗剪承载力，改善车站结构的抗渗性，解决现有钢筋混凝土上翻梁存在的问题，提高结构的整体性能。
