[4] Tiling process The upper end of the connecting stainless steel wire 7Aa of the finishing material side wire 7A constituting the fall prevention wire 7 is preliminarily fixed to the upper and lower intermediate positions on the back surface of each tile 2 to be used. There is.
Then, an elastic adhesive for sticking is applied in a bead shape to the back surface of the tile 2 to which the connecting stainless wire 7Aa is fixed, and the precast concrete slab 1 is stuck in a staggered pattern while shifting from the upper row to the lower row of the base 1a. ..
As shown in FIG. 4, the lower end of the tile 2 of each tile row excluding the lowest tile row is placed on the load receiving plate portion 4B of the load receiving member 4 fixed to the mounting groove portion 3, and the load receiving portion 4B is placed. The plate portion 4B receives and supports the load of the tile 2. In this state, the entire surface of the tile 2 applied to the base 1a of the precast concrete slab 1 is aligned by tapping lightly, the streets of the joints are corrected, and the elastic adhesive is tapped until the elastic adhesive protrudes into the joints to bring them into close contact with each other.

Therefore, even when a large and heavy tile 2 is attached to the base 1a with an adhesive, the load of the tile 2 is applied to the load receiving plate portion 4B of the load receiving member 4 attached to the mounting groove portion 3 of the base 1a. Since the tile 2 can be attached to the base 1a with an adhesive in the received state, the positioning of the tile 2 can be facilitated as compared with the method of adhering the tile 2 to the base 1a only with an adhesive. It is possible to suppress the peeling of the tile 2.

As a result, the connecting stainless wire 7Aa of the tile 2 and the lateral stainless wire 7Bb on the base side are connected, and the load of the tile 2 is received and supported by the load receiving member 4, so that the tile 2 is peeled off, for example. But it doesn't fall.

Moreover, using the load receiving member 4 for receiving and supporting the load of the plurality of tiles 2, the fall prevention wire 7 is oriented vertically through the mounting hole 8a of the mounting portion 8 provided in each load receiving member 4. Since the stainless wire 7Ba can be arranged, it is possible to reduce the number of man-hours for attaching the dedicated wire material arrangement member and the base 1a.

Further, in the method of attaching the tile 2, the tile 2 is generally attached while shifting from the upper row to the lower row. Therefore, after the tile 2 is attached to the base 1a, the tile 2 is detached downward from the attached position. In this space, the connecting stainless wire 7Aa of the tile 2 and the lateral stainless wire 7Bb which is the base side wire 7B can be easily connected. Moreover, the connecting stainless steel wire 7Aa and the horizontal stainless steel wire 7Bb of the connected tile 2 can be sequentially covered with the tiles 2 in the lower row in a good-looking manner.

In the lowest tile row, as shown in FIGS. 2 and 4, the connecting stainless wire 7Aa of the finishing material side wire 7A fixed to the back surface of the tile 2 is a downward extension line portion of the left and right vertical stainless wires 7Ba. It is fastened to the sideways stainless steel wire 7Bb stretched on 7Baa. Therefore, in the lowest tile row, the connecting stainless wire 7Aa fixed to the back surface of the tile 2 is tied to the lateral stainless wire 7Bb stretched between the back surface of the tile 2 and the base 1a to which the tile 2 is attached. After that, the tile 2 is attached to the base 1a with an elastic adhesive while covering the connecting stainless wire 7Aa and the sideways stainless wire 7Bb.
