One of the outer fiber layers 1 on both sides may be buried in the concrete such that the outer fiber layer 1 on the other side is connected to the outer fiber layer 1 buried in the concrete through the connection layer to improve the bonding force of the concrete surface. The resin may be injected into the connection layer so that the connection layer has a solid shape, and then the one-side outer fiber layer 1 may be embedded into the concrete, or the one-side outer fiber layer 1 may be embedded into the concrete, and after the concrete is solidified, the resin may be injected into the connection layer, and the resin may be solidified.
