Connecting joint of concrete filled steel tubular column and precast beam and construction method of connecting joint
The invention discloses a connecting joint of a concrete filled steel tubular column and a precast beam and a construction method of the connecting joint. According to the connecting joint, bottom bars of a reinforced concrete precast beam are converted into anchorage devices which are made of steel wire ropes or prestressed tendons and have certain flexibility at the beam end, rectangular holes are formed in the positions, corresponding to the bottom bars, of the precast beam of a wall plate of the concrete-filled steel tube column, after the precast beam is installed and falls to a certain height, the flexible anchorage devices are bent and stuffed into the rectangular holes, and the flexible anchorage devices extend into the concrete-filled steel tubular column along with continuous falling of the precast beam, so that the precast beam is anchored in a node area. The precast beam bottom bars are anchored in the concrete of the concrete-filled steel tubular column through the flexible anchorage devices, only holes need to be formed in the wall plate of the concrete-filled steel tubular column in advance, on-site welding construction and bolt screwing operation of a traditional concrete-filled steel tubular column and precast beam connecting joint do not exist on a construction site, connecting construction is convenient, quality is easy to control, and meanwhile, the flexible anchorage devices can avoid automatically, special avoiding design is not needed, and structural design and site construction are greatly facilitated.
一种钢管混凝土柱与预制梁连接节点及其施工方法，钢筋混凝土预制梁的底筋在梁端转换为具有一定柔性的钢丝绳或预应力筋制成的锚具，在钢管混凝土柱壁板预制梁底筋对应位置开设矩形孔，预制梁安装下落至一定高度后，将柔性锚具弯曲塞入矩形孔内，随预制梁继续下落柔性锚具伸入钢管混凝土柱内实现预制梁锚固于节点区。本发明预制梁底筋通过柔性锚具锚固于钢管混凝土柱混凝土内，仅需在钢管混凝土柱壁板提前开孔即可，施工现场无传统钢管混凝土柱与预制梁连接节点的现场焊接施工和拧螺栓操作，连接施工方便且质量易于控制，同时柔性锚具可自动避让、无需专门的避让设计，极大地方便了结构设计和现场施工。
