However, the former technique for hoisting the concrete panel 4 using the triangular sling type hanging device 1 is a technique for constructing a construction site such as a scaffold where the wire 3 of the triangular sling type hanging device 1 is used. There is a problem in that the L-shaped metal product 2 may easily come off from the concrete panel 4 when it comes into contact with the product. The latter nylon sling 6
The technique of hanging the concrete panel 4 with a choke by using the method has problems that workability is extremely poor and the overall balance is poor. Further lifting may cause the nylon sling 6 to easily slip and move toward the center of the concrete panel 4, resulting in imbalance and risk.

The lifting hoisting device for a panel according to the present invention is a completely new technique developed in view of the above-mentioned conventional problems. In particular, one end of a short second strip is provided in the middle of the first strip. A lifting hoist having a structure in which parts are fastened to extend a band member in three directions from one point, and a hook portion made of a ring or a hook is provided at the tip of the band member radially extended in three directions. Is.

[0006]

The lifting hoisting device for a panel according to the present invention is a technique in which the above-mentioned conventional problems are fundamentally improved, and the gist thereof is to provide a hook portion at each end. A long first strip and a second short strip having a ring at the tip thereof, the second end of the second strip having no ring is fastened in the middle of the first strip. It is a panel-lifting hanger characterized by being configured as follows.

[0007]

In the present invention, since the short second strip is fastened to the middle of the first strip and the ring is provided at the tip of the second strip, both ends of the first strip are Each can be inserted through the ring of the second strip. In addition, the first band member and the second band member combined as described above can enclose the entire edge portion on the fore edge side of the plurality of laminated concrete panels. Moreover, since both sides of the first strip inserted through the ring of the second strip slide smoothly inside the ring by lifting of the lifting hoist, the concrete panels stored inside are related to the number of panels. It can be tightened as a whole.

Since the hook portions are provided at both ends of the first strip, the hanging hooks of a crane or the like can be easily engaged with these hook portions. Therefore, by using the lifting hoist of the present invention, it is possible to sling and surround the entire end portion of the laminated concrete panels on the fore edge side by a simple operation, and slid. It is possible to lift the entire panel in a well-balanced and stable state without the part of the band material slipping to the center of the panel due to lifting.
