The fixing projections 13 are inserted into the frame 2 to form the taper pins 14. The tile unit 9 can be attached to the frame 2 by fitting it into the hole of the fixing projection 13. Here, it is necessary to make a hole through which the fixing projection 13 penetrates in the skin plate or the like which forms the form frame portion 2, but since a relatively small hole is required, the poured concrete, which will be described later, leaks from the hole. There is no fear.

The surface of the tile 12 mounted on the tile unit 9 is attached to the mounting substrate 1 with an adhesive 11 in advance.
It is adhered to No. 0, but the back surface thereof is adhered to the concrete to be placed and the tile 12 is fixed. Therefore, the back surface of the tile 12 is formed in a corrugated wavy shape so as to improve the adhesion to the concrete.

Then, after the concrete is poured and the required curing time has elapsed, the solidification of the concrete is confirmed, and then the form frame 2 is demolded. This demolding can be performed by shrinking the holding portion 4 and the support member 6 and moving the frame 2 to the center of the tunnel 7.

It shall be removed from the hole of 3 in advance. The demolded state is shown in FIG. When the form unit 2 is removed from the tile unit 9, the back surface of the tile 12 adheres to the solidified concrete. Therefore, thereafter, the work of peeling off the mounting substrate 10 is manually performed. That is, the mounting substrate 10 is the adhesive 1
Although it is adhered to the surfaces of the plurality of tiles 12 by 1, the mounting substrate 10 is peeled off by hand. Then, the plurality of tiles 12 are attached to the inner surface side of the tunnel 7, and the interior finishing process for the inner surface of the tunnel is completed (see FIG. 5).
