Abstract

PURPOSE:To obtain a composite panel having a feeling of natural materials and supplementing respective defects of wooden and stone materials, by mutually laying stone material with wooden material on the front surface. CONSTITUTION:A recessed part 4 is formed on a part of the surface of a wooden plate 2 and a stone material 1 is fitted into the recessed part 4 with an adhesive to form a composite panel A composed of the stone material 1 and the wooden material 2 on the surface. For the stone materials 1, such stones are utilized as thin stones of natural materials like Mikage stone or granite, marble, artificial stones and terrazzo. Next, butt joint plates, solid wooden plates, integrated plates, etc., are used for the wooden plate 1. These wooden plates are made equal or larger than the simultaneously arranged stone material 1 in the thickness. The defects of the wooden plates 2 are supplemented by the merrits of the stone materials 1 and vice versa. In this way, the material mutually arranged with the stone material 1 and the wooden plate 2 on the surface can be easily applied.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a composite panel in which stone and wood boards are arranged side by side.

[Prior art 1] When conventional wall materials and flooring materials are used, they are either made of wood and laminated together, or made of stone and laminated together.

[Problems to be Solved by the Invention] However, each of the above conventional examples has the following advantages and disadvantages, and is difficult to use.

In other words, wood-based materials have a low thermal conductivity, so they feel warm to the touch, have a warm visual appearance, can be worn in a variety of colors and patterns, and have a good walking feel, but their surfaces are soft. There were problems in that it was easily scratched, easily worn out, and easily flammable.

On the other hand, stone visually has a commercial-grade feel, is hard, and is hard to scratch and wear, but it feels cold, easily cracks and chips when impacted, and has a stiff walking feel. Stones with polished surfaces had the problem of being slippery.

Furthermore, the construction methods for each type are different; wood-based materials are attached to the base using nails, screws, adhesives, etc., while stone-based materials are installed using mortar and adhesives. For this reason, mixed use of stone and wood materials has not been practiced in the past.

The present invention was devised in view of the above-mentioned problems of the prior art, and its purpose is to compensate for the drawbacks of wood and stone, and to provide an unprecedented composite panel with a natural feel. There is something to do.

Means for Solving 1 Problem] The composite panel of the present invention has a structure in which stone 1 and wood board 2 are mixed on the surface side.

The back surface of the stone 1 may be reinforced with a reinforcing material 3.

[Function] Since the stone 1 and the wooden board 2 are mixed on the surface side, the disadvantages of the wooden board 2 are compensated for by the advantages of the stone 1, and the disadvantages of the stone 1 are compensated for by the advantages of the wooden board 2. Since it is a panel with stone 1 and wood board 2 installed side by side, it is easy to install a panel with stone 1 and wood board 2 mixed on the surface. It will be finished with construction.

[Examples] The present invention will be described in detail below based on examples shown in the accompanying drawings.

FIG. 1 shows an embodiment of the present invention, in which a part of the surface of a wooden board 2 is recessed to form a recess 4.
are formed, and by fitting the stones 1 into these four parts 4 and gluing them together, a composite panel 8 in which the stones 1 and the wood-based boards 2 are mixed is formed on the front side.

FIG. 2 shows another embodiment of the present invention, and in this embodiment, a stone material 1 and a wooden board 2 are bonded with adhesive to the surface side of a backing material 5 such as plywood, FRP, metal plate, etc. in,
Composite panel A with a mixture of stone 1 and wood board 2 on the front side
is formed.

Incidentally, the stone material 1 used in the present invention is not particularly limited, and may be a thin stone material such as natural stone such as granite, marble, terrazzo, or artificial stone.

In addition, the wood-based boards 2 include veneer plywood, veneer board, laminated wood, etc., but are not particularly limited, but are usually used for floors and walls.
Use stones that are the same or thicker than the stone 1 that will be placed at the same time. If necessary, an anti-slip coating can be applied to improve the anti-slip effect.

The arrangement on the surface of the composite panel A of the stone material 1 and the wood-based board 2 is done taking into consideration the coordination of the respective colors and patterns.
e) 0 ) ([1) (11) (1) (j) (k) (l
), but the arrangement is not necessarily limited to this, and it goes without saying that other arrangements may be used. In Figure 5, the first part of the stone is indicated by hatching.
The non-hatched portion indicates the wooden board 2.

Note that the surface area ratio between the stones 1 and the wooden board 2 looks more luxurious when there are more stones 1, but the area ratio is determined depending on the purpose of each. In addition, there are 2 wooden boards on the side edges.
When the composite panels A are arranged so that the fitting protrusions 7 and the fitting recesses 8 are formed at the side edges of the wooden board 2 as shown in FIG. Connection can be made by fitting into the recess 8.

Further, there may be a step between the stone material 1 and the wooden board 2 arranged on the surface of the composite panel A, but when used as a floor material, it is preferable for walking to have as little step as possible.

There is no particular limit to the size of the composite panel, but when used as flooring material, the size should be 150 to 600 cm in size and 300 to 180 cm in length.
When used as a wall material, the thinner the better, but considering the strength, it is about 6 to 15+sm, and when used as a floor material, it is preferably about 6 to 2 (1wm). .

In addition, since the stone material 1 is weak against impact, it is better to reinforce it by laminating a reinforcing material 3 such as FRP, metal plate, plywood, etc. on the back side as shown in Figures 3 and 4, which increases the bending strength and impact strength, and prevents cracking. ,
It is difficult for defects to occur.

Figure 1156 shows a specific example of the present invention, with a 61ml
A wooden board 2 made of 6I thick oak veneer plywood is attached to the top surface of the backing material 5 made of 11-thick plywood, and a stone material 1 (6mmF7) whose back surface is reinforced with FRP reinforcing material 3 is glued together. Composite panel A with a size of 450x450wm
is formed.

[Effect of the invention 1] In the present invention, as described above, stone and wood boards are mixed on the surface side, so the whole body is not cold compared to the case of only stones, and it can be used as a flooring material. It can be used or walked on barefoot, it is less susceptible to damage than wooden boards alone, and it can provide an unprecedented high-quality composite material that combines the texture of wood with a universal feel. In addition, since the panel is made of stone and wood-based boards installed side by side, it is possible to easily construct a panel with stone and wood-based boards mixed on the surface.

Furthermore, by reinforcing the back side of the stone with a reinforcing material, the overall strength can be increased and the thickness can be reduced.
