Accurate positioning method for reserved hole
The invention relates to an accurate positioning method for a reserved hole, which comprises the following steps of: lowering a reinforcement cage to a construction drawing embedded part design elevation, and welding and connecting a positioning rib with the reinforcement cage; the air bag without air pressure is placed in the reinforcement cage to start inflation; the inflation equipment is inflated by using an air pump, and inflation is stopped when the inflation pressure value reaches enough friction force and bond stress formed by the capsule body and the reinforcing steel bars; observing pressure gauge air of the air bag, and performing subsequent concrete construction after determining that the pressure of the air bag is stable; the air bag is deflated and pulled out when the concrete reaches the initial setting time, and the air bag can be pulled out by manually touching the hardness of the concrete before the inner mold of the air bag is removed and ensuring that the structure edges and corners are not damaged and collapse is not generated. The device is modularized, convenient to disassemble and assemble, easy to manufacture, simple and convenient to operate in the using process and reusable, and does not occupy space after being disassembled. The problem that correction cannot be carried out in subsequent construction is solved.
本发明是一种预留孔洞的精准定位方法，包括将钢筋笼下放至施工图纸埋件设计标高处，使用定位筋与钢筋笼焊接连接；将没有空气压力的气囊置入钢筋笼内开始充气；充气设备使用气泵充气，充气的压力值应达到胶囊本体与钢筋形成足够的摩擦力与握裹力时停止充气；观看气囊的压力表气，确认囊压力稳定后，进行后续混凝土施工；在混凝土达到初凝时间放气拔出气囊，拆除气囊内模前人为触碰混凝土的硬度，在保证结构棱角不破坏、不产生塌陷现象时方可拔出。本装置模块化拆装简便，拆开后不占空间，制作简易，使用过程操作简便，重复利用。解决了后序施工无法进行纠偏的措施。
