Connecting joint of prefabricated beams and support-free prefabricated slabs and construction method
The invention relates to a connecting joint of a prefabricated beams and support-free prefabricated slabs and a construction method. The joint comprises prefabricated beams and prefabricated slabs, wherein the prefabricated slabs are rectangular slabs; the main stress direction of the prefabricated slabs is the span direction, and the slab ends of the prefabricated slabs extend into the beam width range of the prefabricated beams and are placed on the top surfaces of the prefabricated beams so as to bear the construction load and self weight in the construction stage, so that the prefabricated slabs are free of supporting; the prefabricated beams are concrete full-prefabricated beams, and a plurality of shear resistant steel bars are uniformly pre-buried in the middle of the prefabricated beams in the longitudinal direction and extend out of the top surface range of the prefabricated beams; and the slab ends of the prefabricated slabs extend into the beam width range of the prefabricated beams, steel bars of the prefabricated slabs are anchored into the beam-slab joint areas in a staggered mode and are arranged in a staggered mode with the shear resistant steel bars above the prefabricated beams, and finally, the prefabricated beam-slab joint areas are poured on site so as to be connected into a whole. According to the connecting joint of the prefabricated beams and the support-free prefabricated slabs, the prefabricated slabs are free of supporting, and the on-site steel bar work amount and mutual interference of beam-slab steel bar outlet are reduced; and the prefabricated beams and slabs are convenient to install, construction procedures are simple, and the construction efficiency is obviously improved.
本申请涉及预制梁与免支撑预制板连接节点及施工方法，该节点包括预制梁和预制板，预制板均为矩形板；预制板主要受力方向为跨度方向，预制板板端伸入预制梁梁宽范围内并搁置于其顶面，承受施工阶段施工荷载及自重，以实现预制板免支撑；预制梁为混凝土全预制梁，预制梁中部沿纵向均匀预埋多根抗剪钢筋，抗剪钢筋伸出预制梁顶面范围；预制板的板端均伸入预制梁梁宽范围内，预制板的钢筋错位锚入梁板节点区域，并与预制梁上方抗剪钢筋错开布置，最后现场浇筑预制梁板节点区域连接成整体。本申请预制梁与免支撑预制板连接节点不仅免去了预制板支撑，更减少了现场钢筋作业量和梁板出筋的相互干涉；预制梁板安装方便、施工工序简单，施工效率显著提高。
