す。The alkali-resistant synthetic resin fiber net 1 is attached to the mold 2 in a state where the left and right sides are pulled, and the end portion of the alkali-resistant synthetic resin fiber net 1 protruding outside the mold 2 is prevented from being displaced. The fixing portion 3 is provided by welding by means of heating or the like, and then the light green concrete or the lightweight mortar 4 is poured into the mold 2 and, after hardening, is fixed from the mold 2 to the fixing portion 3.
Then, the mold is removed and the plate-shaped lightweight concrete plate 5 is taken out.

Since the specific gravity of the alkali-resistant synthetic resin fiber network 1 is 1.14, it is about 1/7 of the specific gravity of the conventional reinforcing bar network, which is about 1/7, which is very light weight. Even if the cut surface is observed, the alkali-resistant synthetic resin fiber network 1 is uniformly embedded in the lightweight green concrete or the lightweight mortar 4, and the separation of the alkali-resistant synthetic resin fiber network 1 and the lightweight green concrete or the lightweight mortar 4 layer is recognized. The adhesion was good.
