Description of the Related Art As this type of water-permeable grating, for example, as disclosed in Japanese Patent Publication No. 5-36581, the upper surface of the grating portion of the grating main body is composed of the lattice portion and an outer frame surrounding the outer periphery thereof. There is one in which a recessed portion is formed, and a ceramic material is porously bonded by a binder in the recessed portion to form a water permeable material layer (water passage portion). The water permeable material layer is formed for the purpose of preventing slippage and imparting colored decoration while ensuring the permeability of rainwater and the like.

In particular, the water-permeable material layer was liable to be cracked by being bitten by the edge of the lattice portion by vibrating under the load of an automobile passing therethrough, and easily peeled off by slipping the tire of the automobile. An object of the present invention is to solve the above-mentioned conventional problems and prevent cracking or peeling of the water-permeable material layer.

ることができる。The adhesive layer not only enhances the adhesion between the water-permeable material layer and the recess of the grating body, but also improves the durability of the adhesion because it suppresses corrosion of zinc of the plating layer in the recess. That is, the plated zinc contributes to the corrosion protection of the steel grating body because it has sacrificial corrosion resistance.For example, in the recess of the plated grating body, a water-permeable material layer is used without an adhesive layer. If only the binder in this layer is used for adhesion, the zinc of the plating layer in contact with the water permeable material layer will corrode and the adhesion between the water permeable material layer and the grating body will be reduced. It will reduce the adhesion durability of the layer and cause the water-permeable material layer to peel off. In particular, the water-permeable material layer has better drainage than the one filled with a water-impermeable material because it allows rainwater to pass through, but
Corrosion of the zinc occurs at an early stage and reduces the adhesion durability of the water permeable material layer. However, by interposing an adhesive layer between the water-permeable material layer and the recess of the grating body as in the above configuration, it is possible to prevent such premature corrosion of zinc, and to prevent the water-permeable material layer and the grating body from corroding. The adhesion durability can be improved.
