Conventionally, the mounting hardware near the corner portion 50 of the interior panel P is, as shown in FIG. 8, a base-side hardware 51 attached to the tunnel base wall W and a panel upper-side hardware 6 attached to the upper and lower portions of the interior panel.
1 and a panel lower side metal fitting 71.

The base metal piece 51 is composed of a fixed metal piece 52 having a substantially L-shaped cross section, and a locking metal piece 55 having a L-shaped cross-section with its tip end bent and raised. The fixed hardware 52
Is for fixing the panel upper side metal fitting 61, and the horizontal piece 53 is attached to the anchor bolt B provided at a required interval on the base wall W.
And the vertical piece 54 is fixed. Also, the locking hardware 55
Is for locking the lower metal piece 71 of the panel, and the vertical piece 57 is fixed to the anchor bolt B of the base wall with the horizontal piece 56 facing downward.

On the other hand, the panel upper side metal piece 61 has a substantially L-shaped cross section, and a vertical piece 62 is fixed to the upper part of the rear surface of the interior panel P with a bolt, and a horizontal piece 63 is the fixed metal piece 52.
It is placed on the horizontal piece 53 and bolted. Further, the panel lower side metal piece 71 is made of an engraved metal piece, and the upper vertical piece 72 is fixed to the lower part of the rear surface of the interior panel P by 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 metal fitting for mounting the tunnel interior panel, the upper part of the interior panel P is fixed by bolting the panel upper metal fitting 61 and the base metal fitting 51 (fixing metal fitting 52) as described above. Also, the lower part of the interior panel P is also fixed by sandwiching the base-side metal fitting 51 (locking metal fitting 55) between the back surface of the interior panel P and the panel lower metal fitting 71, so that there is no play when mounting the interior panel.

Therefore, when there is an error in the mounting angle of the anchor bolt B and a molding error in the base metal parts 51, 51, the upper metal part 61 and the lower metal part 71, the base metal parts 51, 51 have upper metal parts 61, 51.
