Permanent and temporary combined integral assembly type subway station structure and construction method
The invention discloses a permanent-temporary combined integral assembly type subway station structure and a construction method, the permanent-temporary combined integral assembly type subway station structure comprises a group of opposite prefabricated diaphragm walls, the prefabricated diaphragm walls are sequentially connected with a cast-in-place top waist beam, a cast-in-place middle waist beam and a cast-in-place bottom plate from top to bottom, and the cast-in-place top waist beam is connected with a plurality of prefabricated top cross beams to form a first permanent-temporary combined support; the cast-in-place middle beam is connected with the multiple prefabricated middle cross beams to form a second permanent and temporary combined support; a cast-in-place bottom plate is further included, and a bottom longitudinal beam is arranged on the bottom plate in the longitudinal direction of the station; middle longitudinal beam nodes which are horizontally and crosswise arranged are arranged in the middle of the prefabricated middle cross beams, and partitioned prefabricated plates are mounted between the prefabricated middle cross beams to form prefabricated middle plates; top longitudinal beam joints which are horizontally arranged in a crossed mode are arranged in the middles of the prefabricated top cross beams. Prefabricated composite plates are installed between the prefabricated top cross beams, and concrete is poured later to form a composite top plate structure. Cast-in-place middle columns are connected between the bottom longitudinal beam and the middle longitudinal beam and between the middle longitudinal beam and the top longitudinal beam. Permanent and temporary combination is achieved, later support dismounting is avoided, and the station construction efficiency is improved.
本发明公开一种永临结合整体装配式地铁车站结构和施工方法，包括一组相对的预制地连墙，预制地连墙从上至下依次连接现浇顶腰梁、现浇中腰梁和现浇底板，现浇顶腰梁连接多道预制顶横梁形成第一道永临结合支撑，现浇中腰梁连接多道预制中横梁形成第二道永临结合支撑；还包括现浇的底板，底板上设有沿车站纵向的底纵梁；预制中横梁中部设有水平交叉布置的中纵梁节点，预制中横梁之间安装分块预制板形成预制中板；预制顶横梁中部设有水平交叉布置的顶纵梁节点，预制顶横梁之间安装有预制叠合板并后浇混凝土形成叠合顶板结构；底纵梁和中纵梁之间、中纵梁和顶纵梁之间连接现浇中柱。本发明实现永临结合，避免后期拆撑，提高车站施工效率。
