Packer assembly for crack repair
The present invention relates to a packer for crack repair of a concrete structure, and relates to a packer assembly for crack repair. When the existing nut screwing type and cone type packer structures are combined, the packer is inserted into a gap formed by punching a crack of concrete, the body is rotated, and the soft sleeve is tensioned to expand the packer, the state that the nut is tightly fixed at the lower end of the soft sleeve is maintained. The nut is loosened from the threaded part of the body and presses the soft sleeve to enable the soft sleeve to expand, so that the packer assembly is firmly fixed in a mode of preventing the packer assembly from falling off, the leakage of the repair liquid can be effectively prevented, and meanwhile, when the injection gun is taken out after the repair liquid is injected and filled, the repair liquid is prevented from flowing back.
本发明涉及混凝土结构物的龟裂修复用封隔器，并涉及如下的龟裂修复用封隔器组装体，当进行组合现有的螺母拧紧式和锥形式封隔器的结构并将封隔器插入到在发生龟裂的混凝土的缝隙穿孔而成的间隙且转动本体并拉紧软套来使其膨胀的作业时，维持螺母紧密地固定在软套下端的状态，螺母从本体的螺纹部松开并压迫软套来使其膨胀，由此，以防止封隔器组装体脱落的方式将其牢固地固定，从而可以有效地防止修复液渗漏，同时，当注入、填充修复液后取出注入枪时，防止修复液发生逆流。
