As described in Japanese Utility Model Laid-Open No. 5-71338, there is known one in which a large number of tiles are made into a flat plate and one floor tile panel is installed on the floor surface.

However, recently, as a floor structure of a bathroom, one having a high-class feeling such as a pattern imitating a surface pattern of a natural material such as a stone pattern has been demanded, and simply. Tile installations cannot simply satisfy the demands of consumers.

As a patterned molded article such as a bathtub, as described in, for example, JP-A-4-263942, a coating formed by spraying paints of a plurality of colors is laminated on the back surface of a transparent molded article. Although it is known that it is not easy to apply anti-slip processing to part of the surface of a molded body with a complicated shape such as a bathtub, the floor surface corresponding to the washing place is slippery and dangerous. Not only that, but there is also the problem that the pattern lacks a sense of depth and is not luxurious.

Further, conventionally, as the patterned plate, for example,
Surface layer and back layer of resin concrete mixed with crushed stone of natural stone etc. molded into a plate shape, cloth made of glass fiber and other fibers or paper or film printed It is known that it is interposed between and.

[0006]

However, the resin concrete plate has a poor wall thickness accuracy, and when it is used as a floor structure of a bathroom, hot water cannot flow down well, and it can function as a washing place. It cannot be done, and since it directly appeals to the pattern attached to the surface, there is a problem in that the feeling of depth is not sufficient and there is no sense of quality.

Further, since the printed surface or the like is a smooth surface, the printed board having a printed pattern or the like has a problem in that the feeling of depth is insufficient and the feeling of luxury is not provided.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned conventional problems, and to provide a bathroom floor structure having a non-slip pattern and a pattern with a feeling of depth and a method for molding a bathroom floor. It was made as.
