2. Description of the Related Art For the purpose of protecting the waterproof material (waterproof sheet, waterproof coating film, etc.) applied to the floors of balconies, balconies, flat roofs (rooftops) of general houses and condominiums, or improving the landscape. As a case, a makeup protective plate may be laid. At that time, in order to prevent pooling of water between adjacent decorative protection plates or on the upper surface of the decorative protection plate, conventionally, aggregate with a particle size of about 1 to 5 mm is used as mortar cement or synthetic resin adhesive. Decorative protective plate with good water permeability, such as those that are point-bonded with each other, or those that are obtained by crushing ceramic products such as glass and pottery with a sintering agent (frit) such as glass and clay. Is used.

[0003]

However, in the above-mentioned conventional water-permeable decorative protective plate, dirt such as mud adhering to footwear or dust mixed with rainwater is easily permeated, and the dirt easily adheres. When it got dirty, there was a problem that it could not be easily removed. Moreover, although the conventional water-permeable decorative protective plate is low in cost, in particular, in the case of a mortar cement-based water-permeable decorative protective plate, the surroundings of the aggregate are covered with cement, and the appearance shows a rocky appearance. It was of poor aesthetics. Further, in a conventional cosmetic protective plate having water permeability, dust is easily clogged in the porous holes to cause moss and mold, which is not preferable in terms of appearance and water permeability, and causes clogging by mold. There was a problem that the water permeability decreased.

The present invention has been made in order to solve such a conventional problem. It has water permeability but does not easily get dirt on its surface, and even if dirt is found, it can be easily removed. A water-permeable decorative protective plate that has antifouling properties, is easy to add decoration and design properties to its surface, and has antibacterial and / or antifungal properties in which moss and mold are less likely to occur. For the purpose of provision.

[0005]

The water-permeable decorative protective plate of the present invention which achieves the above object has a recess and a protrusion formed on the surface side of a water-permeable substrate having water permeability, and at least the upper surface of the protrusion. Is formed in a decorative layer having no water permeability (Claim 1). At this time, it is preferable to color the water-permeable substrate so that the adhered dirt is not conspicuous (claim 2), or to form the concave portion like a joint with respect to the convex portion (claim 3). Further, in the water-impermeable decorative layer, the convex portions of the water-permeable substrate are formed of cement slurry containing cosmetic particles, and the surface of the convex portions is polished to expose the cosmetic particles to the surface. Or the adhesive particles applied to the surface of the convex portion, and the cosmetic particles dispersed on the surface of the convex portion are coated with a transparent or semitransparent top coat paint. It is possible to consider the one (claim 5) or the one formed by applying a water-impermeable coating on the surface of the convex portion (claim 6). Furthermore, it is preferable to impart antibacterial and / or antifungal properties to the water-permeable substrate (claim 7).

[0006]

According to the water-permeable decorative protective plate configured as described above, the portions other than the upper surface of the convex portion on which the water-impermeable decorative layer is formed, that is, the concave portion and the side wall portion of the convex portion are water-permeable. Since there is no water pool between adjacent decorative protection plates and on the upper surface of the decorative protection plate, the decorative upper surface is excellent in decoration and design because a water impermeable decorative layer is formed on the upper surface of the convex part. Not only does it become a thing, but it becomes difficult for dirt to soak into or adhere to at least the upper surface of the convex portion where the water-impermeable decorative layer is formed, and even if dirt is attached, it can be easily removed. Even if the concave portion is dirty, the dirt is visually inconspicuous because it is recessed from the upper surface of the convex portion. Further, by coloring the water-permeable substrate to make the stains less noticeable, the stains in the recesses become more inconspicuous, and by imparting antibacterial and / or mildew-proof properties to the water-permeable substrate, moss and mold can be prevented. It becomes difficult to grow, is hygienic, and the water permeability is unlikely to deteriorate.

To prevent the growth of moss and mold, it is preferable to use a metal that has both antibacterial and antifungal properties, such as silver, copper and zinc, or to use an antibacterial and antifungal agent together. .

When the water-permeable substrate 1 is formed, cement: aggregate: light weight aggregate: binder (resin): water, for example, 1: 3: 1: 0.3: 0. Mix in a ratio of 3 and add a colorant for cement appropriately to this, but first dry-blend cement with aggregate and lightweight aggregate, and add a mixture of a binder (resin) and water into it. Prepare a cement slurry that does not have fluidity. Then, this cement slurry is poured into a molding frame in which a concave portion for forming the convex portion 3 of the decorative protective plate A is formed on the inner bottom portion. At this time, if necessary, a reinforcing material such as a metal wire mesh is put in the intermediate layer, followed by pressing at a pressure of 2.9 MPa, followed by curing for 28 days. When carrying out the curing, the mold should be removed from the molding frame 3 days after the curing of the cement slur inside. At this point, the convex portion 3 is formed on the front surface side of the water-permeable substrate 1 (makeup protection plate A) so as to project in the same body. Layer 4 is formed.
