Description

  The present invention relates to a repair member that can easily repair a weakened part of an interior plate installed in a tunnel that has been corroded.

  As shown in FIGS. 11 and 12, an interior plate is installed in a tunnel attached to a highway or the like so as to increase internal lighting efficiency.

  FIG. 13 shows this conventional interior panel mounting structure in a tunnel. Since the interior panel 50 is thus a thin panel, the side wall edge 61 is divided into a tunnel wall surface 60 by dividing it into an upper stage, a middle stage, a lower stage, and the like. 62, 63, and the upper horizontal edge 51 of the interior plate 50 is repaired along the upper horizontal waist edge 61, and the lower horizontal edge 52 is repaired along the lower horizontal waist edge 63, respectively. It is fixed so as to be covered with members 64 and 65.

  Further, in the middle of the interior plate 50, the vertical edge portions 53 and 54 of both interior plates are pressed against the horizontal trunk edge 62 which is disposed in the middle stage exposed from the gap 66 provided between the interior plates. It is attached by fixing with the presser fitting 67.

  In the figure, 68 is an anchor bolt driven into the wall surface 60, 69 is a mounting seat fixed to the anchor bolt, and the horizontal trunk edge is bolted 70 to the mounting seat 69.

  Such horizontal trunk edges 61, 62, 63, repair members 64, 65, presser fittings 66, etc. are used after galvanizing the SS material. Rust is generated by exposure to chemicals and exhaust gas, and after many years, the thickness decreases, weakens and may fall.

  Moreover, since the appearance is very unsightly, the corroded mounting member must be replaced as appropriate.

  Conventionally, the repair member of the mounting member that has installed the interior panel in such a tunnel, the interior panel itself has not been corroded, but may be damaged when it is removed, so it must be installed in advance What has been manufactured in the same manner as the interior plate and its mounting member is completely replaced on site (see, for example, Patent Documents 1 and 2).
