<P>PROBLEM TO BE SOLVED: To provide a hanging hook for a concrete product, by which the concrete product can be pulled up without damaging the surface of the concrete product and the hanging mechanism of which can easily be locked to an embedding member embedded beforehand in the concrete product to improve working efficiency. <P>SOLUTION: The hanging hook 10 for the concrete product includes: the embedding member 30 one end face 30A of which is exposed and the other end face of which is embedded in the concrete product 50; and the hanging mechanism 20 which is freely attached to/detached from the embedding member 30. The round bar member 21 of the hanging mechanism 20 is inserted into the embedding member 30 and then the round bar member 21 is turned by a knob 24, so that the retaining projection part 21B of the round bar member 21 is moved along the slope part 30G of the embedding member 30 and fit into a positioning groove 30H for the retaining projection part to lock the round bar member 21 to the embedding member 30. <P>COPYRIGHT: (C)2012,JPO&INPIT |
