Metro station opening position middle plate supporting structure and supporting method thereof
The invention discloses a metro station opening position middle plate supporting structure and a supporting method thereof, the metro station opening position middle plate supporting structure comprises a prefabricated middle column, a middle beam and a prefabricated middle longitudinal beam, the prefabricated middle longitudinal beam is provided with a horizontally-supported prefabricated middle plate, the prefabricated middle plate is provided with an opening, and the opening is internally connected with a supporting steel bar. During installation, the prefabricated middle longitudinal beam is connected with the supporting profile steel and the prefabricated middle plate; then pouring the laminated slab and simultaneously pouring the cast-in-place boundary beam at the edge of the opening; and finally removing the supporting profile steel. The section steel support is arranged at the hole opening position of the middle plate, so that the middle plate can be used as a whole in the splicing process, the stress requirement that the middle plate serves as a replacement support to bear water and soil pressure on the outer side of a foundation pit in the construction stage is met, and supporting is convenient when a cast-in-place edge beam is arranged on the hole edge. And the connection of the prefabricated middle plate and the hole edge cast-in-place beam can be synchronously realized with the pouring of the middle plate laminated layer, so that the synchronous pouring equal strength of the cast-in-place joint and the laminated layer of the middle plate can be realized, and the extra construction period is not increased.
本发明公开了一种地铁车站开孔处中板支撑结构及其支撑方法，包括预制中柱、中梁以及预制中纵梁，所述预制中纵梁上设置有水平支撑的预制中板，所述预制中板上设置有开孔，所述开孔内连接有支撑钢筋。在安装时，将预制中纵梁与支撑型钢连接和预制中板连接；然后浇注叠合板并同时浇注开孔边缘的现浇边梁；最后拆除支撑型钢。在中板的开孔位置设置了型钢支撑，使中板在拼装的过程中能作为一个整体进行，满足施工阶段中板作为换撑承受基坑外侧的水土压力的受力要求，且便于在孔边设置现浇边梁时的支撑。而预制中板与孔边现浇梁的连接可以与中板叠合层的浇筑同步实现，可以实现现浇节点与中板的叠合层同步浇筑等强，不增加额外的施工工期。
