Prefabricated floor structure
The invention provides a prefabricated floor system structure. The prefabricated floor system structure comprises a prefabricated concrete floor slab, a pre-embedded steel plate, a connecting cover plate and a fastener, an upper pre-embedded steel plate and a lower pre-embedded steel plate are respectively pre-arranged on the top surface and the bottom surface of the connecting end of the precast concrete floor slab; a through hole penetrating through the connecting end, the upper embedded steel plate and the lower embedded steel plate is formed in the prefabricated concrete floor connecting end; via holes are formed in the two ends of the connecting cover plate. When the two prefabricated concrete floors are in butt joint, the two ends of the upper connecting cover plate and the two ends of the lower connecting cover plate are attached to the upper embedded steel plate and the lower embedded steel plate respectively. Fasteners penetrate through the through holes and the via holes to connect and fix the two prefabricated concrete floor slabs. The connecting cover plate can coordinate the deformation of the two adjacent precast concrete floor slabs and provide bending resistance and shearing resistance rigidity, so that the shearing resistance rigidity and the bearing capacity of the slab joint are greatly improved, and the connecting cover plate has the advantages that the structure is simple, construction is convenient and rapid, the construction period can be greatly shortened, and later local replacement and updating are facilitated.
本发明提供了一种预制楼盖结构，其包括预制混凝土楼板、预埋钢板、连接盖板和紧固件；预制混凝土楼板的连接端顶面和底面上分别预设有上预埋钢板和下预埋钢板；以及，预制混凝土楼板连接端上设置有贯通连接端上下以及上预埋钢板和下预埋钢板的贯通孔；连接盖板上两端设置有过孔；两个所述预制混凝土楼板对接时，上下两块连接盖板的两端分别贴靠在上预埋钢板和下预埋钢板上；紧固件穿过贯通孔和过孔后将两个所述预制混凝土楼板连接固定。本发明中连接盖板可协调两相邻预制混凝土楼板的变形，同时提供抗弯和抗剪刚度，从而极大地增加了板缝处的抗剪刚度和承载能力，构造简单、施工方便快捷，可大大缩短工期，且便于后期局部置换更新等特点。
