The leg 3 of the bifurcated shaft 1 is inserted into the insertion hole formed in the thickness direction, the steel wire 4 is connected to the bulging portion 2 in the vertical direction, and the leg 3 bulges into the concrete outer wall 5. Since the projecting portion 2 and the steel wire 4 are fixed so as to be located on the tile surface (layer), the concrete outer wall 5 and the tile surface (layer) can be partially bound to prevent peeling. In particular, in the present invention, since the forked shaft body 1 having the above-mentioned flexibility is used instead of a simple driving pin, the connecting structure between the steel wire 4 and the bulging portion 2 has flexibility, so that the temperature change and the wet / dry It is possible to follow contraction and earthquakes caused by the movement of the vehicle, and suppress and absorb the resulting movement. For example, in the structure of FIG. 4, even if the upper tile surface shifts in the left-right direction as shown by the arrow with respect to the lower concrete outer wall 5, the connection structure between the stretched steel wire 4 and the bulging portion 2 is changed. The movement can be absorbed without any loss. When a conventional driving pin is used, it cannot follow shrinkage due to a temperature change or the like or an earthquake or the like, so that a crack (crack) or the like is generated and the effect of preventing spalling is not sufficiently exhibited.
