Description of the Related Art As shown in FIG. 6 and FIG. 7 showing a front view thereof, in a tunnel such as a road, a decorative interior panel P is mounted on a tunnel base wall W at a corner portion 50a and an intermediate portion 50b. Attached by hardware. Conventionally, as shown in FIG. 8, the mounting hardware of the interior panel P includes a base hardware 51 mounted on the tunnel base wall W, a panel upper hardware 61 and a panel lower hardware 71 mounted on upper and lower portions of the interior panel. Consisting of

The metal fittings 51 on the base side include a fixing metal piece 52 having a substantially L-shaped cross section, and a locking metal piece 55 having a shape in which a tip end portion having an L-shaped cross section is bent and raised. The fixed hardware 52
Is for fixing the panel upper metal part 61, and the horizontal pieces 53 are attached to anchor bolts B provided at required intervals on the base wall W.
The vertical piece 54 is fixed with the top facing upward. Also, the locking hardware 55
The vertical piece 57 is fixed to the anchor bolt B on the base wall with the horizontal piece 56 facing down.

On the other hand, a panel upper metal part 61 has a substantially L-shaped cross section, and a vertical piece 62 is fixed to an upper portion of a back surface of the interior panel P with a bolt, and a horizontal piece 63 is fixed to the fixed metal part 52.
Is mounted on the horizontal piece 53 and bolted. The panel lower metal piece 71 is formed of a fastener-shaped metal piece, and the upper vertical piece 72 is fixed to the lower portion of the back surface of the interior panel P with a bolt, and the lower vertical piece 73 is a rising piece of the locking metal piece 55. It is inserted inside 58 and locked.

However, in the hardware for mounting the tunnel interior panel, the upper portion of the interior panel P is fixed by bolting the panel upper hardware 61 and the base metal body 51 (fixed hardware 52) as described above. The lower part of the interior panel P is also fixed by sandwiching the base metal piece 51 (locking piece 55) between the back surface and the panel lower metal piece 71, so that there is no play when the interior panel is attached.

Accordingly, if there is an error in the mounting angle of the anchor bolt B or a molding error in the base metal pieces 51, 51, the upper metal piece 61, and the lower metal piece 71, the upper metal piece 61, The lower metal piece 71 must be forcibly attached, and unexpected stress is applied to the interior panel P, which may cause cracks or large cracks in the interior panel P. Therefore, precision is required for the work of attaching the anchor bolts and the work of attaching the interior panel. In particular, when the tunnel base wall W is in an arc shape, it is difficult to accurately mount the anchor bolts and the interior panel, and no crack occurs when the interior panel is a panel base with a tile. Even a small amount of stress may act on the adhesive surface of the tile to peel the tile from the panel substrate.

Furthermore, two types of base-side hardware (the locking hardware 55 and the fixing hardware 52) must be used for the lower and upper panels of the vertically adjacent interior panels, which are bothersome. In order to fix various types of base-side hardware to the base wall, there was also poor workability in which two anchor bolts had to be attached in close proximity.
