[0004]

However, in the above mounting method, since the operator directly lifts the outer wall panel by hand, there is a risk that the weight of the outer wall panel may damage the hand or finger when lifting. Also, since the lower end of the outer wall panel is gripped and lifted, the outer wall panel should be supported in a substantially vertical posture while maintaining balance during lifting or during work of attaching the upper end of the panel to the beam. However, there is a risk that the outer wall panel may be accidentally tumbled toward the inside of a house or the like.

In particular, when an operator who lifts the outer wall panel damages his / her finger or the like, a fall accident to the indoor side is likely to occur. In that case, the work of attaching the upper end portion of the outer wall panel to the beam. Since the worker is usually located on the indoor side of the outer wall panel, there is a risk that this worker may be the underlay of the outer wall panel.

It should be noted that if it is possible to support not only the lower end portion of the outer wall panel but also the side end portion at the time of lifting the outer wall panel, it is considered that the above-mentioned fall accident can be reduced. If another outer wall panel is already attached, the joint size between adjacent outer wall panels is small, for example, about 10 mm.
Since it is necessary to prevent fingers from being caught between adjacent outer wall panels, the side edges of the outer wall panels cannot be supported,
There was a situation in which the outer wall panel had to be supported and lifted only at the lower end.

[0007]
