Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a decorative material whose surface is covered with an inorganic decorative board.

(Problems to be solved by conventional technology and device) Generally, hard inorganic decorative boards such as plate-shaped stone materials and tiles have a texture that cannot be obtained by other base materials, and are excellent in strength and abrasion resistance. It is used as a decorative material such as floor material or wall material. However, since the hard inorganic decorative board has poorer thickness accuracy than general building materials, for example, when it is applied to a floor material, if it is butt-laid and laid on a floor base, a step is generated, which is dangerous. For this reason, conventionally, a mortar layer was provided on the floor base, and the thickness of this mortar layer was adjusted to absorb the thickness unevenness of the hard inorganic decorative board, and construction was performed so that no step was generated on the floor surface. It is necessary and requires a lot of man-hours at the construction site, which leads to a cost increase.

On the other hand, in order to eliminate the above-mentioned problems, by sticking a substrate of an appropriate thickness on the back surface of the hard inorganic decorative board, it is possible to absorb the thickness unevenness, but in this method the thickness of the hard inorganic decorative board Since the thickness is not uniform, if the above-mentioned substrate is subjected to actual processing to make the thickness of the entire decorative material uniform and to increase the bonding strength, the actual parts cannot be fitted together because the dimensions from the base to the actual part are different. There is a problem.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a decorative material which is excellent in workability and can obtain a large bonding strength.

(Means for Solving the Problem) In order to achieve the above-mentioned object, a decorative material according to the present invention is a hard inorganic makeup material such as stone material via a plate thickness adjusting plate that can be ground on a substrate whose side end faces are actually processed. The plate is laminated and integrated.

Therefore, according to the present invention, the strength that can be used for the flooring material,
Not only is it possible to obtain a wear-resistant decorative material, but it is also possible to absorb the uneven thickness of the hard inorganic decorative board by grinding and adjusting the thickness of the thickness adjusting plate, so that there is a step between adjacent decorative boards. It can be installed without the occurrence of cracks and can be completely bonded even if it is installed on the same base.

Therefore, it is not necessary to adjust the thickness at the construction site as in the conventional example, the workability is improved, and the cost can be reduced.

That is, the thickness can be adjusted by grinding the plate thickness adjusting plate, so that the same thickness of plate material can be used for all the boards, so the real part on the boards has a constant distance from the back surface. , They can be fitted together and joined together. Therefore, the bonding strength can be increased while maintaining the workability described above.

In particular, if the substrate is made of wood, not only adhesive fixing but also nailing fixing can be performed, so that the decorative material of the present invention can be directly applied on the joists of a general house, which is convenient.

(Embodiment) An embodiment according to the present invention will be described below with reference to the accompanying drawings of FIG. 1 and FIG.

The decorative material 1 according to the present embodiment has a male portion 2 on the opposite end face.
Further, the hard inorganic decorative plate 6 is laminated and integrated on the substrate 4 provided with the female part 3 with the grindable plate thickness adjusting plate 5 interposed therebetween.

The substrate 4 is made of plywood or the like that can be actually processed, and in order to prevent warpage due to the difference in shrinkage ratio with other members, a plurality of cutout grooves 7 are provided in parallel on the bonding surface with the plate thickness adjusting plate 5. Has been done.

The grindable plate thickness adjusting plate 5 is for absorbing the thickness unevenness of the hard inorganic decorative plate 6, and a homogeneous and grindable plywood or fibrous plate that does not cause warpage during sticking is used.

As the hard inorganic decorative board 6, for example, natural or artificial marble, granite, stone materials such as cement terrazzo, and ceramic tiles are used. A wide fitting groove 8 is provided on the surface of the hard inorganic decorative plate 6, and a decorative material 9 made of a different material is fitted and integrated.

In the present embodiment, the different decorative plates are not joined and integrated by abutting between the separate hard inorganic decorative plates, but the fitting groove 8 provided in one hard inorganic decorative plate 6 is used.
In addition, since the decorative plate 9 is integrally fitted, there is an advantage that a gap is unlikely to occur.

Next, in the decorative material 1 according to the present embodiment, the plate thickness adjusting plate 5 is attached and integrated on the back surface of the hard inorganic decorative plate 6, and the plate thickness adjusting plate 5 is ground to adjust the thickness. Plate thickness adjusting plate 5
The assembling work is completed by sticking and integrating the substrate 4 with.

In addition, the side end surface of the hard inorganic decorative board 6 is the male part 2 of the substrate 4,
When it is located inside the abutting surface of the female part 3,
As shown in FIG. 2, when they are abutted against each other, a gap is formed at a constant interval between the side end faces of the adjacent hard inorganic decorative plates 6, 6, and the caulking material 10 can be filled in this gap.

Further, when the side end faces of the plate thickness adjusting plates 5 are located inside the side end faces of the hard inorganic decorative plate 6, the adjacent plate thickness adjusting plates
The gap between the facing side end surfaces of 5, 5 is larger than the gap between the facing side end surfaces of the adjacent hard inorganic decorative plates 6, 6, and even if the caulking material 10 is filled, the caulking material 10 spreads to the end. There is an advantage that it is hard to drop out.
