DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof decorative building material used for a wall material and the like and a built-in structure of the building material, and a waterproof decorative surface material formed by laminating a decorative layer on the surface of a base layer. The present invention relates to a waterproof decorative building material which is configured to be adhered to a surface of a board, and a construction structure of the building material.

[0002]

2. Description of the Related Art Conventionally, as this kind of waterproof decorative building material, for example, Japanese Patent Application Laid-Open No. 3-38346 or FIG.
FIG. 7 (A) shows a waterproof decorative sheet composite panel (first known technique) shown in FIG.
A waterproof concrete plate (second known technology) shown in (B) is known.

[0003] In the first known technique, as shown in FIG. 6 (A), a fibrous sheet material 51 such as glass fiber is provided with a waterproof layer 52 made of an elastic acrylic resin-based aqueous emulsion or the like.
A waterproof decorative sheet 54 is formed by sequentially laminating a colorful pattern decorative layer 53 made of a curable acrylic silicone resin or a paint.

[0006] Next, as shown in FIG. 6 (B), the waterproof decorative sheet 54 is adhered to the surface of a concrete panel 55, and a small edge 55 a of the concrete panel 55 is further attached.
The waterproof decorative sheet 54 is also wrapped around the waterproof decorative sheet 54, and the side edge of the waterproof decorative sheet 54 is adhered to the fore-edge portion 55a to form the waterproof decorative material 5.
6.

Further, in FIG. 6 (B), joints 57 are formed by arranging two waterproof decorative building materials 56 in parallel, and a sealing material 58 and a backup are provided between the waterproof decorative sheets 54 of the joints 57. The structure in which the waterproof joint is constituted by the material 59 is described.

A second known technique is shown in FIG.
As shown in (B), a synthetic resin adhesive 61 mixed with a filler is applied to the outer peripheral surface of the lightweight concrete plate 60, a waterproof member 62 is adhered on the upper surface thereof, and a decorative layer made of paint or the like is formed thereon. This is a structure of a waterproof concrete plate 64 formed by applying a coating 63.

[0007]

However, both the waterproof decorative building material 56 shown in the first known technique and the waterproof concrete board 64 shown in the second known technique have a plurality of decorative sheet layers attached to the surface of the concrete board. In addition, the decorative sheet layer is wrapped around the small edge of the concrete plate as it is, and it is adhered and fixed using an adhesive. Due to the thickness of the rolled part, the adhesiveness is poor, and the decorative sheet layer floats. It was easy and could cause problems in quality. In addition, there is a problem that the productivity is inferior and the occurrence of defective products increases.

In particular, when a decorative sheet layer is wound around a small edge portion of a concrete plate and bonded and fixed using an adhesive, a large amount of adhesive is used, or an adhesive having strong adhesive force is used. If not, there is a problem that the decorative sheet layer in the fore-edge portion peels off.

Further, when the waterproof decorative building material 56 and the waterproof concrete plate 64 are built into a building frame to form joints, a thick decorative sheet layer is provided at the small edge of the concrete plate. In addition, the width of the joint becomes narrow, and there is also a problem that a working width for inserting a sealing gun for performing a sealing essential for waterproofing cannot be secured. Furthermore, since the sealing material applied to the joints is filled between the decorative layers made of paint or the like of the decorative sheet layer, there is a concern that the sealing material may easily peel off and fall off over a long period of time.

[0010] The waterproof decorative building material and the construction structure of the building material according to the present invention are a completely new technology developed in view of the above-mentioned conventional problems, and are a waterproof decorative surface in which a decorative layer is laminated on the surface of a base layer. Attach the material to the surface of the concrete plate and wrap only the base layer of the waterproof decorative surface material around the edge of the concrete plate and fix it with fixing hardware such as pins and staplers. The present invention provides a completely new technique that prevents the decorative sheet layer from being degraded, prevents the adhesive property from being reduced at the small edge of the decorative sheet layer, and prevents the decorative sheet layer from floating.

[0011]

A sheet-shaped waterproof decorative surface material formed by laminating a decorative layer on the surface of the layer is adhered to the surface of a smooth concrete board using an adhesive, and is exposed at an edge of the waterproof decorative surface material. The waterproof decorative building material is characterized in that only the base layer provided as above is wound around the small edge of the concrete plate and fixed with fixing hardware such as pins and staplers.

In the waterproof decorative building material described above, a decorative decorative surface material is formed by laminating a surface decorative layer of a base layer comprising a base layer and an intermediate layer, and the waterproof decorative surface material is adhered to the surface of a concrete plate. Therefore, it is possible to construct a beautiful makeup material having a high waterproof property.

[0013] In addition, at the small edge of the concrete plate,
Since only the base layer of the waterproof decorative surface material is entangled and fixed, the thickness of the fore-edge portion can be reduced. Further, since the decorative layer of the waterproof decorative surface material is not bent and entangled in the fore-edge portion, it is possible to prevent the adhesiveness of the waterproof decorative surface material from deteriorating and prevent the waterproof decorative surface material from floating.

Further, since the base layer of the waterproof decorative surface material caught in the small edge portion of the concrete plate is firmly fixed by a fixing hardware such as a pin stapler, the base plate is subject to aging, thermal expansion or contraction. Also, there is no peeling.

The construction structure of a building material according to the present invention is a technique which fundamentally improves the above-mentioned conventional problems, and the gist of the invention is that a base layer and a decorative layer are provided on the surface of a concrete plate having a smooth surface. In a structure in which a waterproof decorative building material comprising a layer and a base layer is stuck and only the base layer is wound around the small face of the concrete plate and fixed with fixing hardware such as pins and staplers, the waterproof decorative building material is built in the building frame. A building material installation structure, characterized in that a sealing material is filled between base layers of joints formed by a plurality of waterproof decorative building materials.

In the above-mentioned construction structure of building materials, a waterproof decorative surface material comprising a base layer and a decorative layer is adhered to the surface of a concrete plate having a smooth surface, and only the base layer has a small edge of the concrete plate. Since the waterproof decorative building material which is wrapped around the surface and fixed firmly with the fixing hardware is built in the building frame, the width of the joint formed by the parallel waterproof decorative building materials can be widened.

Furthermore, since the sealing material is filled between the base layers on both sides of the joint, the sealing material can be fixed to the base layer, thereby preventing the sealing material from falling off.
