Embodiment 1.
As shown in FIG. 1, a plurality of rectangular tiles 4 arranged in a plurality of rows in the vertical direction V are provided so as to cover the surface of the wall panel 100 on the outdoor side. Each tile 4 is attached to the panel body 1 via a plurality of vertical rails 2 extending in the vertical direction V and a plurality of horizontal rails 3 extending in the horizontal direction H.
The vertical direction V and the horizontal direction H do not have to be strictly vertical or horizontal. The vertical direction V is the height direction of the building in which the wall panel 100 is constructed, and the horizontal direction H It is sufficient if the direction is substantially parallel to the eaves and foundation of the roof.
The vertical rails 2 and horizontal rails 3 are formed by processing hot-dip zinc-aluminum-magnesium alloy-plated steel sheets by a pre-notch roll forming method.

As shown in FIGS. 2 and 3, the vertical rail 2 is embedded in the panel body 1 made of concrete. An anchor 23 extending in the horizontal direction H is integrally connected to the vertical rail 2 by welding, and the anchor 23 is embedded in the panel body 1 together with the vertical rail 2 . In addition, as shown in FIG. 2, each anchor 23 is provided along the vertical direction V at regular intervals. A plurality of projecting portions 22 are formed on the wall outer side E of the vertical rail 2 so as to be arranged side by side in the vertical direction V at regular intervals. Each of the lateral rails 3 is engaged with each of the protrusions 22 .

The shape of the longitudinal rail 2 will now be described in more detail with reference to FIGS.
As shown in FIG. 4, the vertical rail 2 has a projecting portion 22 formed by raising a part of the lips 21 on both sides of the C-shaped steel to the wall outer side E. As shown in FIG. As shown in FIG. 5(a), the projecting portion 22 of the vertical rail 2 has a substantially parallelogram shape. Further, as shown in FIG. 5(b), a gap D1 is provided between the lips 21 on both sides of the vertical rail 2. As shown in FIG. Further, an anchor 23 is attached to the wall inner side F of the vertical rail 2 by welding. As shown in FIG. 4, the anchor 23 is a rod-shaped member extending in the horizontal direction H, and the central portion 23a curves toward the wall outer side E. As shown in FIG.

Further, as shown in FIG. 6( a ), the horizontal rail 3 is formed with a bent portion 3 a that can be engaged with the projecting portion 22 of the vertical rail 2 . Further, as shown in FIG. 6(b), an oblong bolt hole 3b having a horizontal direction H as a longitudinal direction is formed in a portion closer to the upper end than the bent portion 3a.

The deformed washer 31b is inserted inside the vertical rail 2 in the direction indicated by the two-dot chain line in FIG. 9 with the bolt 31a engaged in the central portion. When the bolt 31a is turned, the deformed washer 31b rotates as indicated by the arrow, and the acute angle portion S of the parallelogram of the deformed washer 31b comes into contact with the lip 21 of the vertical rail 2. As shown in FIG. As a result, the deformed washer 31b can sandwich the vertical rail 2 and the horizontal rail 3 between itself and the circular washer 31c. Therefore, the fixing member 31 having the deformed washer 31b can easily fix the horizontal rail 3 to the vertical rail 2 with a small number of parts.

The shape of the deformed washer of the fixing member 31 is not limited to the parallelogram shape shown in FIG. 9, and may be a shape like the deformed washer 131b shown in FIG. That is, the deformed washer 131b has a shape in which a pair of sharp-angled portions S of a parallelogram are cut to form straight portions 131d. Therefore, the fixing member 31 having the deformed washer 131b can attach the horizontal rail 3 to the vertical rail 2 more stably.

Next, as shown in FIG. 11B, the lower end 3d of the horizontal rail 3 is brought into contact with the step of the lower end groove 4c of the recess 4a of the tile 4, and the upper end 3c of the horizontal rail 3 is also brought into contact with the tile 4. .
Further, as shown in FIG. 11(c), the tile 4 is further lifted upward, the lower end 3d of the horizontal rail 3 is engaged with the lower end groove 4c of the recess 4a of the tile 4, and then the lower end groove 4c is centered. to rotate the tile 4 as shown in FIG. 11(d). Then, as shown in FIG. 11(e), the horizontal rail 3 is housed inside the concave portion 4a of the tile 4. As shown in FIG. In this state, the position of the tile 4 is shifted downward so that the upper end 3c of the horizontal rail 3 and the upper end groove portion 4b of the tile 4 come into contact with each other. Thereby, the tile 4 is fitted and attached to each of the lateral rails 3 .

As described above, in the wall panel 100 according to the first embodiment, since the plurality of vertical rails 2 extending in the vertical direction V are embedded in the panel body 1 made of concrete, the vertical rails 2 are provided in the panel body 1.
