Abstract

PROBLEM TO BE SOLVED: To improve strength, and prevent scattering to surroundings so as to prevent damage to environment even if a permeable board is damaged. SOLUTION: A long fiber reinforced fabric sheet 3 of one layer that consists of a glass fiber sheet is laminated between a surface layer member 1 and a lower layer member 2. The glass fiber sheet is, for instance, made of the satin of no-alkali glass wherein 33 fibers in a horizontal direction and 65 fibers in a vertical direction per 25 mm are oriented. Glass besides mullite, silicon carbide, carbon, and metal wire are acceptable for a material of the long fiber reinforcing fabric sheet. It is desirable to apply one layer or more and ten layer or less, especially one layer or more and three layer or less as the number of sheets of laminating. It is desirable to apply 20 mm or more and 425 mm or less as the length of the fibers. If scraps of tile porcelain is used for the surface layer member and a recycling product such as waste glass materials is used for the lower layer member, it is possible to contribute to the reuse of resources.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water-permeable board, and more particularly to a water-permeable pavement for forming a water-permeable pavement surface on a sidewalk, a pedestrian bridge, a park, a sports facility, around a building, between a home's entrance soil, an edge, a porch, etc. Regarding the board.

2. Description of the Related Art A permeable plate prevents rainwater exceeding the city sewage capacity from flowing into an urban sewage facility by returning water remaining on a pavement surface during rainfall to the underground (permeation), thereby preventing untreated sewage water. It works to prevent environmental (water) pollution from being released into rivers or the ocean.

Conventionally, a water-permeable plate uses, as aggregate, gravel, sand, slag, colored glass, crushed rubber, urethane chips, shells, porous volcanic rock, tourmaline ore, etc., and cement, epoxy resin, tar, Mix with asphalt, urethane resin, acrylic resin, vinyl acetate resin,
It was manufactured by compression molding followed by solidification or mixing and firing with water glass.

Since the water-permeable plate thus configured has a long fiber reinforced woven sheet laminated between the surface member and the lower layer member, it has a high bending strength and is connected by the long fiber reinforced woven sheet even if it is damaged. 1 does not fly.

According to a second aspect of the present invention, in the first aspect of the present invention, in particular, the long fiber reinforced woven sheet is formed of at least one of glass, mullite, silicon carbide, carbon, and metal wire. A board is provided. According to the third aspect of the present invention, there is provided the water-permeable plate according to the first aspect of the present invention, in which one to three layers of long fiber reinforced woven fabric sheets are laminated.

In order to secure the smoothness of the surface member 1 at the time of pouring, a pressure press is performed. After pressing, it is held for 24 hours to dry and solidify (steps 101 to 106).

The long fiber reinforced woven fabric sheet 3 is cut into a required size after an epoxy adhesive is applied to both sides (steps 107 to 109). After the surface member 1 is dried and solidified, the long fiber reinforced woven sheet 3 coated with the adhesive is laminated and dried and solidified for 3 hours (steps 110 to 11).
