Different-strength-grade concrete mixed pouring prevention device for beam-column joints and construction method of different-strength-grade concrete mixed pouring prevention device
The invention relates to a mixed pouring prevention device for concrete of different strength grades of beam-column joints and a construction method. Comprising a plurality of cylindrical flexible air bags which can be inflated and deflated, and the flexible air bags are located between a high-grade component and a low-grade component; double valves for inflating and deflating are arranged at the top of the flexible air bag; the cylindrical flexible air bag is simple in structure, the cylindrical flexible air bag can be placed between to-be-isolated high-grade concrete and low-grade concrete, due to the fact that the skin of the inflated cylindrical flexible air bag has certain softness and expansibility, gaps between reinforcing steel bars and a protective layer can be filled, the high-grade concrete and the low-grade concrete can be effectively isolated, and convenience and reliability are achieved.
本发明涉及一种梁柱节点不同强度等级混凝土防混浇装置及施工方法；包括多个可以充气放气的圆柱形柔性气囊，该柔性气囊位于高标号构件与低标号构件之间；柔性气囊顶部布设有充气放气的双阀门；本发明结构简单，该圆柱形柔性气囊可以放置在待隔离高低标号混凝土之间，由于充气后的圆柱形柔性气囊表皮有一定的柔软度和膨胀性，可以填充钢筋与保护层之间的空隙，可有效隔离高低标号混凝土，方便可靠。
