<p>PURPOSE:To easily attach a receiving metal for supporting a laid substance by having a pair of fixing members, which are fixed to the upper wall and the lower wall, respectively, of the a tunnel, and a mounting piece, which is mounted between both fixing members. CONSTITUTION:Fixing members 1a and 1b are attached to the specified upper and lower walls of a tunnel T, and the curved surface wall 17 of a reinforcing member 14 is attached to the specified sidewall of the tunnel T. Next, connecting members 6a and 6b are supported loosely by both fixing members 1a and 1b, and a mounting piece 7 is supported loosely by both connecting members 6a and 6b, and also one end 14a of the reinforcing member 14 is fixed to a mount. Furthermore, the mounting piece 7 and the reinforcing member 14 are fixed. And, the assembling is completed by attaching the base a of a receiving metal a into a specified hole 12. Hereby, even if the cross section of the tunnel T is circular, or even if it is separated from the sidewall, the receiving metal fitting a for supporting a laid substance can be easily attached.</p> |
