Dry-type connecting joints of assembly type concrete floor slabs
The invention provides dry-type connecting joints of assembly type concrete floor slabs. The joints comprise prefabricated concrete beams and the prefabricated concrete floor slabs, the prefabricatedconcrete floor slabs are floor slabs with edge ribs, high-strength bolts are pre-buried at the tops of the prefabricated concrete beams, and screw sleeves are pre-buried on the side surfaces of the prefabricated concrete beams; conical holes with big upper portions and small lower positions are reserved in the portions, connected with the prefabricated concrete beams, on the prefabricated concretefloor slabs, and pre-buried bolts are reserved at the tops of the portions, connected with the adjacent prefabricated concrete floor slabs, on the prefabricated concrete floor slabs; the pre-buried high-strength bolts at the tops of the prefabricated concrete beams penetrate through the conical holes in the prefabricated concrete floor slabs, conical filling blocks are inserted into the conical holes, and then gaskets are covered and are fastened through nuts; the edge ribs of the prefabricated concrete floor slabs are tightly and fixedly connected with the screw sleeves pre-buried in the side surfaces of the concrete beams through bolts; and the adjacent prefabricated concrete floor slabs are connected with each other through opposite pulling of the pre-buried bolts on the top surfaces of the prefabricated concrete floor slabs, and high-strength bolts of connecting steel plates and the edge ribs of the floor slabs, and flexible filling layers are arranged. According to the joints, cast-in-place concrete is not needed, the structure is simple, and the construction is fast.
本发明提供一种装配式混凝土楼板的干式连接节点，包括预制混凝土梁以及预制混凝土楼板，预制混凝土楼板为带边肋楼板，预制混凝土梁的顶部预埋高强螺栓，侧面预埋螺丝套筒；预制混凝土楼板上与预制混凝土梁的连接部位预留有上大下小的锥形孔、与相邻预制混凝土楼板的连接部位的顶部预留预埋螺栓；预制混凝土梁顶的预埋高强螺栓穿过预制混凝土楼板上的锥形孔，锥形填充快插入锥形孔，上覆垫片并用螺母紧固；预制混凝土楼板的边肋采用螺栓与混凝土梁侧面预埋的螺丝套筒紧固连接；相邻预制混凝土楼板的相互连接，是通过其顶面的预埋螺栓与连接钢板、楼板边肋的高强螺栓对拉实现并设置柔性填充层。本发明无需现浇混凝土，构造简洁施工快捷。
