流し込む必要があった。2. Description of the Related Art FRP (glass fiber reinforced plastic,
A bathroom floor structure made of fiberglass reinforced plastic generally requires a plurality of ribs b to be provided on the back surface a for reinforcement as shown in FIGS. 6 and 7. In order to manufacture a bathroom floor structure made of FRP, molding by a mold is used. In order to mold the above-described rib, a groove for forming a rib is formed in the mold. It was necessary to pour the material into.
【０００３】[0003]
【発明が解決しようとする課題】従って、従来の浴室床
構造では、リブ形成のために多量の材料を必要とすると
共に、金型には上述の如くリブ形成用の溝を複数必要と
し、金型の製造が面倒であり、かつ、コスト高になって
いた。また、成型時に金型の溝に十分材料が入り込まな
い場合があり、このような場合、製品の不良（リブ欠け
等）が生じ、歩溜りが悪くなり、さらにコスト高を招い
ていた。そのため、従来では、成型条件（型の温度分布
等）の設定が難しかった。Therefore, in the conventional bathroom floor structure, a large amount of material is required for forming the ribs, and the mold requires a plurality of grooves for forming the ribs as described above. The manufacture of the mold was cumbersome and costly. Further, there is a case where the material does not sufficiently enter the groove of the mold during molding, and in such a case, a defect of the product (such as chipping of a rib) occurs, the yield is deteriorated, and the cost is further increased. Therefore, conventionally, it has been difficult to set the molding conditions (such as the temperature distribution of the mold).

じ、美観を損なう虞れがあった。Further, since FRP is a plastic composite material, which is a material obtained by combining a resin with a reinforcing material (glass fiber), the fiber enters a groove for forming a rib during molding. It was difficult to obtain sufficient strength for the ribs. In addition, in the product, the shrinkage ratio differs between the portion having the rib and the portion having no rib, which may cause "sink" and impair the aesthetic appearance.
