When composite panels are used for the exterior walls of warehouses, factories, offices, commercial buildings, etc., the exterior wall horizontal wall construction method is now often adopted. Conventionally, this method of constructing side walls of an exterior wall involves wrapping the central part of the exterior wall panel with a nylon sling, or fixing a jig and lifting it up, and attaching it to both ends of the panel 1 as shown in Figure 5. Pass the hook bolt 3 etc. through the bolt through hole 2, and insert the tip of the hook bolt 3 into the panel support material 4.
The panel 1 was attached so as to be horizontal in the longitudinal direction.

[Problems to be Solved by the Invention] In the conventional mounting method as described above, the ALC panel or a composite panel with the surface finish of the ALC panel is moved to the mounting point using a lifting device such as a crane winch. When the hanging sling is hung up to a certain point, it is extremely troublesome to attach and detach the hanging sling, and there is a problem in that it damages the finished surface of the exterior wall panel. Furthermore, when using a clamp plate, the hanging work is carried out in a narrow working space, which not only makes the work itself difficult and dangerous, but also causes damage to the panel. In order to solve these problems, there is a method of attaching suspension bolts to the panel in addition to the main tightening bolts, but this poses the problem of high cost.

The present invention has been made to solve these problems, and aims to provide a hanging metal fitting that can be inserted into a tightening bolt that is screwed into the anchor metal fitting of a panel, and a panel mounting method using the same. purpose.
