And a surface layer plate 10 having a thickness of about 3 mm fixed via a filler 9 having a thickness of about 75 mm for the purpose of heat insulation and the like.

The material of the corrugated metal plate 8 is not limited to a steel plate (painted steel plate, galvanized steel plate, stainless steel plate, etc.), and may be another metal plate such as an aluminum plate or a copper plate.

The depth of the dovetail-shaped valley portion 8A of the structural material 8 is about 2
It is 5 mm and formed at intervals of about 120 mm. In the case of the dovetail-shaped valley portion 8A, the engaging portion on which the wedge member of the fixing fitting to be described later is hooked is the inclined side surface of the valley portion 8A, but the engaging portion is a ridge formed in the valley portion 8A. Can be However, in order to firmly fix the outer wall panel 7 to the beam 11 fixed to the frame of the structure by the wedge effect of the wedge member, the dovetail-shaped valley portion 8A is preferable.

The filler 9 is a lightweight mortar such as perlite mortar or a foam mortar. The surface plate 10 is
Examples include flexible boards, perlite boards, and decorative steel sheets.

As the outer wall panel 7, as shown in FIG. 3, the surface layer plate 10 may be directly fixed to the structural material 8 made of corrugated steel plate without the filling material 9.

Reference numeral 12 is a fixing member, which is composed of a wedge member 13 inserted into the dovetail-shaped valley portion 8A of the structural member 8, a wedge member 13 and a connecting member 14 for connecting the beam 11. . The wedge member 13 has a trough portion 8A from one surface side of the structural material 8.
It has a width dimension that can be inserted into the inside of the valley portion 8A, and has a length dimension that engages with the inclined side surface of the valley portion 8A when it is rotated by approximately 90 ° inside the valley portion 8A and does not come out of the inside of the valley portion 8A. There is.
That is, the width dimension of the wedge member 13 is narrower than the width dimension of the inlet of the valley portion 8A of the structural material 8, and the length dimension of the wedge member 13 is the valley portion 8A.
The length is rotatable within A and is wider than the width of the entrance of the valley 8A. Therefore, when a tensile force is applied to the wedge member 13 inserted in the valley 8A by the coupling member 14, the inclined side surface of the valley 8A and the inclined surface of the wedge member 13 are in close contact with each other, and the outer wall panel 7 is It is firmly fixed to the beam 11 by the wedge effect.

The connecting member 14 is fixed to the wedge member 13,
It is composed of a threaded rod 15 that is inserted through the beam 11 and a nut 16 that is screwed into the threaded rod 15. The wedge member 13 and the screw rod 15 may be integrally fixed in advance, or the screw rod 15 may be screwed and fixed in the wedge member 13. Further, the connecting member 14 may be formed by a bolt that is screwed into the wedge member 13.

According to the fixing structure for the outer wall panel of the present invention described above, since the wedge member 13 before being fixed is freely movable along the valley portion 8A of the structural member 8, the outer wall panel 7 is provided.
The vertical positioning of the can be done very easily. In addition, in order to provide a clearance for lateral positioning of the outer wall panel 7, the insertion hole of the screw rod 15 formed in the beam 11 may be formed horizontally long.

Reference numeral 17 is a panel receiver made of angle steel or the like, which is fixed to the frame of the structure. The panel receiver 17 has the following functions. That is, according to the fixing structure of the outer wall panel of the present invention described above, the vertical load of the outer wall panel 7 is received only by the wedge effect of the wedge member 13, and an excessive load cannot be endured. Therefore, in order to compensate for this, the vertical load of the outer wall panel 7 is received by the panel receiver 17.

According to the fixing structure for the outer wall panel of the present invention, which is configured as described above, the following is performed.
The outer wall panel is fixed to the beam of the structure. That is, the outer wall panel 7 is placed on the panel receiver 17, the screw rod 15 previously fixed to the wedge member 13 is inserted into the screw rod hole formed in the beam 11, and bolted by the nut 16. Thereby, the outer wall panel 7 is firmly fixed to the beam 11 by the wedge effect of the wedge member 13. At this time, in order to engage the wedge member 13 with the valley portion 8A of the structural member 8, the screw rod 15 is held by hand, the wedge member 13 is inserted into the valley portion 8A, and then the screw rod 1 is inserted.
Turn 5 by 90 ° by hand.

As shown in FIG. 4, the bracket 18 is fixed in advance at a predetermined position of the beam 11, and a groove 19 into which the screw rod 15 can be inserted from above is formed in the bracket 18, or as shown in FIG. , The screw rod 15 is inserted into the lightning metal object 20 slidable along the beam 11, or as shown in FIG. 6, the bolt 21 is passed through the lightning metal object 20 and the wedge member 13 is screwed into the bolt 21. Beam 11
The wedge member 13 can be easily set to the. Particularly, in the cases of FIGS. 5 and 6, the outer wall panel 7 can be easily positioned in the lateral direction.

[0031]

As described above, according to the present invention, the engaging portion is formed in the trough portion of the structural material made of the corrugated metal plate forming the outer wall panel to fix the outer wall panel to the structure. The fixture is fixed to the wedge member, which has a width dimension narrower than the inlet width dimension of the valley portion, is rotatable in the valley portion, and has a length dimension wider than the inlet width dimension, and the wedge member and the structure. By using the connecting member for connecting the beam and the beam, the following useful effects are brought about. The wedge effect of the wedge member allows the outer wall panel to be firmly fixed to the beam. Since the wedge member is inserted into the structural material, the head of the bolt and the like are not exposed from the outer surface of the outer wall panel, so that an excellent aesthetic appearance can be obtained. Since it is not necessary to form a countersink hole in the outer wall panel, it can also be applied to a finished outer wall panel. When fixing the outer wall panel, the outer wall panel can be freely moved in the direction of the trough, so that the outer wall panel can be easily positioned when fixing the outer wall panel to the beam.
