Laminated concrete slab abutted seam structure connected by clustered steel plates and construction method of laminated concrete slab abutted seam structure
The invention discloses a laminated concrete slab abutted seam structure connected through bundled steel plates and a construction method thereof.The abutted seam structure comprises a prefabricated slab, the prefabricated slab comprises the bundled steel plates and longitudinal steel bars, the bundled steel plates are evenly distributed along the edge of the prefabricated slab, and the ends, close to the edge, of the longitudinal steel bars are connected with the closest bundled steel plates; the parts far away from the edge are uniformly spaced; at least one edge of the prefabricated plate is provided with a step part; the cluster steel plate is partially exposed on the surface of the step part; the bundling steel plates are connected through connecting pieces; and a post-cast laminated layer is arranged on an area defined by the step part and the connecting piece and the surface of the prefabricated slab. Ribs do not come out from the edge of the prefabricated plate, the longitudinal steel bars in the prefabricated plate are welded to the bundling steel plate, the longitudinal steel bars do not need to stretch out, the machining arrangement difficulty is remarkably reduced, transportation and installation inconvenience is avoided, and the bundling steel plate is stable in connection performance; through lap joint of the connecting pieces, better construction tolerance is achieved; and additional steel bars or reinforcing steel bars are arranged, so that the bearing redundancy at the abutted seam can be improved.
本发明公开了一种采用集束钢板连接的叠合混凝土板拼缝结构及其施工方法，拼缝结构包括预制板，预制板包括集束钢板和纵向钢筋，集束钢板沿预制板边缘均匀分布，纵向钢筋靠近边缘的一端与其最近的集束钢板相连，远离边缘的部分均匀间隔；预制板至少一个边缘设置台阶部，集束钢板部分暴露在台阶部表面；集束钢板与集束钢板之间通过连接件相连；台阶部、连接件围合而成的区域及预制板表面设置后浇叠合层。本发明预制板边缘不出筋，预制板内纵向钢筋焊接到集束钢板上，无需将纵向钢筋伸出，显著降低加工布置难度，避免运输和安装不便，集束钢板连接性能稳定；通过连接件搭接，具有更好的施工容差；设置附加钢筋或补强钢筋，可提升拼缝处承载冗余度。
