Prefabricated bottom plate with cast-in-place surface and construction method
The invention provides a prefabricated bottom plate with a cast-in-place surface and a construction method, and belongs to the field of fabricated construction. According to the prefabricated bottom plate, transverse rib connecting pieces are arranged on the non-cast-in-place surface side of the prefabricated bottom plate, perpendicular to transverse stress steel bars in the bottom plate and along the splicing edges of the prefabricated bottom plate, each transverse rib connecting piece comprises an inner side end welded to the adjacent transverse rib and a reserved welding end exposed out of the plate at the same time, the length of the transverse rib connecting pieces is equal to the length of the splicing edges or accounts for a preset proportion of the length of the splicing edges, and the transverse rib connecting pieces are uniformly distributed on the splicing edges; and when cast-in-place is carried out, the reserved welding ends at the edges of the two spliced prefabricated bottom plates are connected with each other in a welded mode. According to the prefabricated bottom plate, the dispersed transverse ribs are connected into a whole through the transverse rib connecting pieces, so that the shearing force borne by the end parts of the bottom plate is transmitted in the transverse direction and the longitudinal direction at the same time, and is shared among the plurality of prefabricated bottom plates, the shearing damage caused by overlarge shearing force is prevented, the integrity of the spliced prefabricated bottom plate is enhanced, the anti-seismic and anti-shearing performance of a floor slab is improved, the operation is simple and feasible, and the construction difficulty is reduced.
本发明提供了一种具有现浇面的预制底板及施工方法，属于装配式施工领域。所述预制底板通过在预制底板的非现浇面侧、垂直于底板内横向受力钢筋、沿预制底板拼接边，设置横筋连接件，横筋连接件包括同时焊接于相邻横筋上的内侧端和露在板外的预留焊接端，横筋连接件长度与拼接边等长或占拼接边长度的预定比例且均匀分布于拼接边上；当进行现浇时，两个相互拼接的预制底板边缘处的预留焊接端相互焊接连接。本发明通过横筋连接件将分散的横筋连为一体，使底板端部受到的剪切力同时沿横、纵两个方向传递，同时在多个预制底板间分担，防止剪切力过大造成剪切破坏，增强拼接预制底板的整体性，提高楼板的抗震、抗剪性能，操作简单易行，降低了施工难度。
