BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative veneer for construction, which is used by applying it directly to a floor surface or a wall surface to finish these surfaces beautifully.

[0002]

2. Description of the Related Art Generally, the first or
As shown in the figure, it is common to directly attach a large number of decorative plates cut into a predetermined shape to finish the surface. Conventionally, there is a decorative board of this type in which a surface material having a predetermined color or pattern is attached to the surface of a wooden plywood. The decorative board having such a wood plywood as a base material has heat resistance and a certain surface hardness, but has the following disadvantages. In other words, with a veneer made of wood plywood as a base material, it is not possible to directly attach it to the floor surface made of concrete that is not a perfect flat surface with the entire surface in close contact, causing problems such as peeling. It is easy to occur. -For veneer made of wood plywood as a base material, if the wall surface is curved, direct attachment is difficult. -In order to make such a decorative plate into a predetermined shape, it has to be cut at a factory or the like, but it is also difficult to cut so that the edge of this decorative plate does not have a crisper. In particular, when cutting this decorative board at a construction site, it is difficult to prevent the scrapes from being generated, and the workability is poor.

On the other hand, hitherto, those using a soft material such as vinyl chloride, lino tile, or homogeneous style as a base material have been proposed. However, although these do not have the above-mentioned drawbacks, there is a problem that not only the surface hardness when used as a flooring material is insufficient but also the heat resistance is poor.

[0004]

As described above, there is no conventional decorative board that can withstand long-term use as a flooring material, and it cannot be directly attached, or at least has poor workability. I had a problem. Therefore,
An object of the present invention is to provide a decorative board for construction which has sufficient heat resistance and surface hardness and is excellent in workability at low cost.

[0005]

[Means for Solving the Problems] Therefore, the inventors have conducted earnest studies on how to construct a decorative board that does not have the above-mentioned problems that the conventional technology has. As a result, they came up with a decorative board having the following configuration. That is, the present invention relates to a decorative board for construction, which is obtained by adhering a vinyl chloride base material having a thickness of 1 mm or more and a covering material via an adhesive layer, wherein the covering material contains an abrasion resistant substance.
0.6 mm thick, integrally molded by stacking a protective layer made of melamine resin, a pattern layer made of printed resin-impregnated pattern paper and a core layer made of resin-impregnated core paper.
It is a decorative board for construction characterized by comprising the following laminated materials.

That is, the feature of the present invention resides in the constitution of a covering material laminated and adhered to the surface of a vinyl chloride base material (hereinafter, simply referred to as a "vinyl chloride base material"). In order to impart wear resistance to the protective layer constituting
It is made of resin containing fine powder of high hardness and abrasion resistance such as alumina and SiC, and this protective layer is further lined and bonded with a resin impregnated pattern and a resin impregnated core paper with pattern printing. The point is that it is composed of the laminated material. The detailed structure of this cover material will be described along with the description of the embodiment.

The first reason why it is necessary to make the total thickness of the laminated covering materials to be 0.6 mm or less is that if the thickness of this covering material is larger than 0.6 mm, the elasticity and the flexibility of the vinyl chloride base material are increased. This is because the flexibility cannot be utilized and it becomes impossible to completely absorb the unevenness of the floor surface or the wall surface formed of concrete or the like in the architectural decorative board. The second reason why the total thickness of the covering material needs to be 0.6 mm or less is that when the thickness of the covering material becomes larger than 0.6 mm, the shape such as shown in FIG. When sheared to, the burrs are likely to occur on the front edge of the cover material,
This is because shearing becomes difficult. Further, the reason that the thickness of the vinyl chloride base material is set to 1 mm or more is that it is necessary for the close-adhesion work regardless of the shape of the floor surface.

[0008]

Next, the operation of the decorative board for construction according to the present invention will be described together with its construction mode. First, this architectural decorative board is provided by being pre-cut into a shape as in the construction example of FIG. 1 in order to form a certain pattern by arranging a large number of this decorative board. In the case of using wood plywood as a base material, it is necessary to slowly cut it with rotating saw blades so as to prevent crisping at the ends, but the decorative decorative board according to the present invention can be used for both exterior and PVC base materials. Since there is no rustling at all, the end can be beautifully finished. This also applies to the case where the architectural decorative board is cut into smaller pieces according to the site. In other words, the cutting of this decorative veneer for construction can be performed without using the saw, without using time-consuming work, by using construction scissors, a cutter knife, or the like, without causing sharpness in a short time. .

Such a decorative board for construction and a smaller cut piece of this construction are directly attached to the floor surface made of concrete having small irregularities by using an adhesive. Therefore, the unevenness of the floor surface can be sufficiently absorbed. This is because the back surface of the decorative veneer for construction is lined with the above-mentioned flexible PVC base material, and since this PVC base material is the floor side, it absorbs small irregularities on the floor surface. It effectively works, and the architectural decorative board can be directly attached to the floor surface in a completely adhered state. Therefore,
Even after a long time has passed, there is no problem such as peeling of the architectural veneer. Further, in such a decorative board for construction, the protective layer of the surface covering material is the outermost layer, and since the abrasion-resistant fine powder is dispersed in this protective layer, it is extremely durable. There is. Moreover, since the abrasion-resistant fine powder has excellent heat resistance, the heat resistance of the decorative board is also improved.

In addition, in the case of this decorative board for construction, since it is lined with a vinyl chloride base material, it is possible to sufficiently absorb the vibration generated by a person walking on it or the movement of furniture, etc., and no noise is transmitted to the downstairs. . Of course, this architectural veneer
It can be used enough to make a beautiful wall surface. In this respect, the wall surface may be formed of a curved surface, but as described above, since the architectural decorative board itself has sufficient flexibility due to the vinyl chloride base material, It is possible to directly attach it along the curved surface.
