DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hanging device for hanging a wall panel made of lightweight cellular concrete or the like vertically.

[0002]

2. Description of the Related Art For example, lightweight cellular concrete (AL)
When constructing the outer wall of a building with wall panels such as C), the wall panels are stacked between steel members that are erected separately from each other. At this time, a hanging tool that lifts the wall panels is used. Various types of structures have been proposed as such hanging devices for wall panels. For example, as a relatively simple structure,
A hanging bolt or the like is directly attached to both sides or the upper end of the concrete panel, and a rope such as a wire rope is hung on the hanging bolt.
No. 84, Japanese Utility Model Application Laid-Open No. 62-112285, and the like. However, in such a structure in which the suspension bolts are directly attached to the concrete panel, the suspension bolts must be removed from the concrete panel after the movement of the wall panel, and the operation of attaching and detaching the suspension bolts is complicated. Further, when the suspension bolt is attached to the concrete panel in this way, it is necessary to bury a nut member screwed into the suspension bolt inside the concrete panel, and the structure of the concrete panel is complicated. Therefore, as a suspending tool for suspending the concrete panel while sandwiching and holding the concrete panel, for example, a plurality of link arms are crossed to each other and pivoted, and the upper end side of the link arm is lifted by a wire rope or the like to thereby reduce the weight of the concrete panel. Thus, there is known a suspender configured to pivot a lower end portion of a link arm inward to clamp a concrete panel. Such a hanging tool that clamps a wall panel with a link arm that is pivotally connected to the open / close operation does not need to attach a hanging bolt or the like to the concrete panel, and the detaching operation of the concrete panel and the hanging tool is easy. That is,
This type of suspending device has a structure in which each link arm is rotated in the closing direction by the vertical load of the lifted concrete panel to clamp the concrete panel. Since the vertical of the concrete panel is not added, the hanging tool can be easily removed from the concrete panel. However, since a sandwich type suspender which is opened and closed by such a link mechanism sandwiches the concrete panel by its own weight, the concrete panel is erroneously made during the descent of the concrete panel, for example, a scaffold for construction. However, there is a risk that the concrete panel may come off from the hanging tool and fall, causing a problem in terms of safety.

An object of the present invention is to solve such a problem, and an object of the present invention is to provide a hanging device for a wall panel that can reliably suspend the wall panel without processing the wall panel. I do.

By tightening the fixing means in a state where the wall panel is vertically sandwiched between the pair of side plates and the bottom plate of the support plate, the front plate and the contact plate of the panel presser and the front rising wall of the support plate. A wall panel is sandwiched between the frame and the frame body in the front-rear direction.

[0005] With the above arrangement, the wall panel is placed on the support plate with the support plate fixed to the lower end of the frame body fixed by the fixing means, and then the panel retainer is lowered along the frame body to lower the panel. By fixing the panel retainer to the frame body by fixing means with the retainer in contact with the upper edge of the wall panel, the wall panel is sandwiched between the support plate and the panel retainer, and further, the support plate and the panel retainer and the frame The front and back of the wall panel are sandwiched between the body and the wall panel is hung with the wall panel securely sandwiched in this way, so that the wall panel does not drop during transport of the wall panel, and there is no danger to work and it is safe Can be done.
