Subway upper cover reserved joint bar positioning device and construction method
The invention discloses a subway upper cover reserved joint bar positioning device and a construction method, relates to the technical field of constructional engineering, and solves the problems that in the prior art, a column reserved joint bar is prone to steel bar deviation in the upper cover concrete pouring process, and the steel bar deviation can generate large adverse effects on the bearing capacity and the anti-seismic property of a reserved column. According to the specific scheme, according to the subway upper cover reserved joint bar positioning device, a formwork supporting structure comprises a plurality of reserved angle steel horizontally arranged on the side wall of a subway structure column, and the reserved angle steel is connected with the bottom of vertical connecting angle steel; the tops of the vertical connecting angle steel on the opposite side wall faces of the subway structure column are connected through the horizontal positioning angle steel to form a rectangular frame for supporting the formwork, and the formwork is fixedly connected with the rectangular frame. The steel bar positioning structure is arranged on the inner side wall of the formwork and comprises a notch positioning steel plate provided with a plurality of notches for positioning the reserved joint bars, and the notch positioning steel plate is fixedly matched with the positioning steel bars and used for locking the reserved joint bars.
本发明公开了一种地铁上盖预留插筋定位装置及施工方法，涉及建筑工程技术领域，解决了现有技术中柱预留插筋在上盖混凝土浇筑过程中容易产生钢筋偏位，钢筋偏位会对预留柱承载力与抗震性能产生较大不利影响的问题，具体方案如下：一种地铁上盖预留插筋定位装置，模板支撑结构包括多个水平设于地铁结构柱侧壁的预留角钢，预留角钢连接竖向连接角钢底部，地铁结构柱相对侧壁面上的竖向连接角钢顶部通过水平定位角钢连接以形成支撑模板的矩形框架，模板与矩形框架固定连接；钢筋定位结构设于模板内侧壁，其包括设有多个凹口以定位预留插筋的凹口定位钢板，凹口定位钢板与定位钢条固定配合，用于锁定预留插筋。
