Full-prefabricated floor slab connecting joint
The fully-prefabricated floor slab connecting joint comprises a fully-prefabricated floor slab and a steel beam, the fully-prefabricated floor slab comprises a floor slab body, shear-resistant key grooves are formed in the end face of the floor slab body at intervals, the shear-resistant key grooves are sunken towards the interior of the floor slab body, the exteriors of the shear-resistant key grooves are open, and horizontal reinforcing bars exposed out of the floor slab body are arranged on the end face where the shear-resistant key grooves are located at intervals; the horizontal reinforcing bars are of closed U-shaped structures, bolt holes are formed in the thickness direction of the floor slab body and penetrate through inner cavities of the shear-resistant key grooves, and sleeves are embedded in the inner walls, opposite to the bolt holes, in the shear-resistant key grooves. When the floor slabs are connected, the horizontal reinforcing bars at the ends of the two fully prefabricated floor slabs are overlapped in a staggered mode, the shear-resistant steel plates are inserted into the shear-resistant key grooves, holes are formed in the shear-resistant steel plates, the shear-resistant steel plates are fixed into the shear-resistant key grooves through bolts, the longitudinal reinforcing bars are arranged in the internal spaces of the horizontal reinforcing bars, and the longitudinal reinforcing bars and the horizontal reinforcing bars are bundled and fixed. And concrete is poured at the splicing position of the two fully-prefabricated floor slabs. The overall stress performance, the tensile performance and the shear resistance of the floor slab can be enhanced.
本发明涉及一种全预制楼板连接节点，包括全预制楼板和钢梁，全预制楼板包括楼板本体，楼板本体的端面上间隔设置抗剪键槽，抗剪键槽向楼板本体内部凹陷，抗剪键槽外部敞口，抗剪键槽所在端面上间隔设置外露于楼板本体的胡子筋，胡子筋采用闭口U型结构，沿楼板本体厚度方向开设螺栓孔，螺栓孔贯通抗剪键槽内腔，抗剪键槽内与螺栓孔相对的内壁上预埋套筒。楼板连接时，两个全预制楼板端部的胡子筋交错搭接，每个抗剪键槽内插入抗剪钢板，抗剪钢板上开孔，用螺栓将抗剪钢板固定在抗剪键槽内，胡子筋内部空间设置纵向钢筋，纵向钢筋与胡子筋捆扎固定，在两个全预制楼板的拼接处浇筑混凝土。本发明可增强楼板的整体受力性能及抗拉、抗剪性能。
