A screw hole 90 is bored in the side surface of the grip portion 88.

The fastener 84 is fixed to the lattice frame 16 by fitting the grip portion 88 onto the upper part of the vertical member of the lattice frame 16 from the front side and tightening the butterfly bolt 38 into the screw hole 90. At this time, by pressing the hanging piece portion 86a against the upper edge of the wall panel 18, the wall panel 18
Fix the upper side of.

Note that this fastener 84 may be removed after the adhesive has hardened, or may be left as is.

According to the construction method of this embodiment, the wall panel 18 is mainly bonded to the lattice frame 16 with an adhesive, and the fasteners 70 and 84 are used auxiliary. The number of .84 used is small. For this reason, the fasteners 70.84 are attached to the lattice frame 1.
6.The work time for attaching the 6 is shortened. Moreover, after fixing with the fasteners 70 and 84, the next work can be carried out regardless of the curing time of the adhesive. Therefore, work efficiency is extremely high.

Note that when the fastener 84 is removed after the adhesive has hardened, the cost of parts can be further reduced.

In the wall panel construction structure according to this embodiment, the back surface of the wall panel 18 is bonded to the lattice frame 16, and since the bonding area between the wall panel 18 and the lattice frame 16 is large, the fixing strength of the wall panel 18 is is large.

Note that the method of the present invention is suitable for attaching panels such as tile panels, FRP panels, and decorative cement boards that cannot be driven with screws or nails from the front side.

[Effects] As described above, according to the wall panel construction method of the present invention, the wall panel is attached to the base member using an adhesive, and the top and bottom of the wall panel are fixed using fasteners.
Fewer fasteners are needed, the amount of work required for installation is reduced, and construction time can be shortened. Furthermore, since only a small number of parts are required for installation, the cost of parts can be reduced. Further, according to the present invention, the wall panel is temporarily fixed with a fastener until the adhesive used to attach it to the rail hardens, so that tight and high adhesive strength can be obtained. Moreover, since the fasteners are left as they are at least on the lower side of the wall panel, the reliability of mounting the wall panel is extremely high.

In the method of the present invention, work efficiency is extremely high because the work can proceed to the next work after fixing with the fastener is completed regardless of the curing time of the adhesive.
