Description

[Detailed explanation of the idea] This invention relates to a new decorative composite board.

Decorative laminates are used for many purposes such as interior decoration of buildings, furniture, and cabinets for electrical appliances.

Conventionally, this type of decorative board has been made of a decorative veneer adhered to a plywood base or solid wood.
However, due to the lack of wood resources and resulting export bans in wood-producing countries, concerns have arisen about rising wood prices and insufficient supply of wood materials.
In order to deal with this, it has become necessary to develop a decorative board that uses as little wood as possible.

Therefore, as shown in FIGS. 1 and 2, a decorative board 3 has been developed in which a decorative veneer 2 is attached to the top and four side surfaces of the fiberboard 1. However, if this decorative board is made of solid wood, the wood grain that is continuous with the top surface 5 appears on the side surface 4, which would be the end surface of the wood, and the joint part 6 of the decorative veneer is bent and pasted. This has disadvantages in that it is aesthetically inferior due to the formation of wood grains, and its commercial value is reduced because it cannot be clearly seen as solid wood.

The decorative composite board of the present invention includes a flat non-wood base material having fitting grooves on four side surfaces parallel to the top and bottom surfaces, a decorative veneer stuck to the top surface of the base material, and a decorative veneer affixed to the top surface of the base material. It is a solid board having a convex part that can be fitted into the groove, and is made of wood chips for the side surface with decorative processing such as chamfering and wood chips for the end of the end surface, and the fitting groove and the By fitting with the convex portion, the wood chips for side surfaces are attached to one opposing side surface of the non-wood base material, and the wood chips for end ends are attached to the other opposing side surface of the same base material. It is characterized by the fact that

In other words, with this structure, the composite board of the present invention is mainly made of non-wood base material, but the top surface is covered with a decorative veneer, and the four sides are decorated with wood scraps of solid wood. By using such materials, even if decorative processing such as matching and carving is performed on the wood scraps, especially those for the end of the wood,
It looks as if it were a decorative board made from solid wood, and the design effect is extremely good.

Furthermore, in the composite board of the present invention, if the grain of the decorative veneer on the surface and the grain of the wood chips on all four sides, especially the wood chips for end chamfering, are oriented in the same direction, this is even more preferable, as it eliminates any sense of incongruity or unnaturalness in the flow of the grain in the appearance of the decorative board.

Moreover, the decorative composite board of the present invention is a composite structure of a non-wood base material in the center and wood scraps on the four sides.
Non-wood substrates such as flat gypsum boards generally do not expand or deform much due to changes in temperature and humidity, and have higher dimensional stability than solid board materials. Therefore, the composite board of the present invention does not suffer from warping or cracking (partial peeling of the decorative veneer), which is seen in conventional solid wood decorative boards.
It has a very long service life without any defects such as these. Furthermore, when gypsum flat board is used as the non-wood base material, it has excellent workability and also provides high sound insulation, heat insulation, and noncombustibility effects.

Therefore, the decorative composite board of the present invention is useful as an interior material for houses, stores, etc., and especially as a decorative material for walls. Specifically, by arranging and gluing a large number of decorative composite boards of the present invention on a wall surface vertically and horizontally, it is possible to create a wall surface that at first glance looks like decoratively processed solid wood.

Embodiments of the present invention will be described below based on the drawings.

FIG. 3 is an exploded perspective view of the main parts of the decorative composite board of the present invention, showing a flat gypsum board 10 as a non-wood base material with fitting grooves 9 on the four side surfaces and cardboard sheets 8, 8 laminated on both the top and bottom surfaces. , side wood scraps 11 having a protrusion 12 attached to the periphery of the gypsum flat board 10 using the mounting groove 9, and wood scraps 1 at both ends of the protrusion 13.
1 shows a wood scrap 14 showing a butt end surface for a butt end having a fitting groove 15 for one convex portion 12.

By fitting each of these components together using the mating grooves 9 and the protruding portions 12 and 13 with an adhesive, a composite board 16 for decorative panels of the present invention is obtained, in which the entire side of the gypsum flat board 10 is surrounded by wood chips, as shown in Figure 4.

In addition to the gypsum board as in the above example, other non-wood base materials include gypsum board, fiberboard,
Particle board, asbestos, perlite board, light calcium board, pulp cement board, rock wool board, etc. can also be used, and in the case of weak base materials, reinforcing materials such as paper, cloth or synthetic resin sheets can be used. It is preferable to laminate them on the front and back sides. However, when using a gypsum board with cardboard laminated on the top and bottom surfaces, by fitting and gluing the side wood chips, the wood chips for the end, and the base material, it is possible to connect both wood chips and the base material. The holding power increases, thereby protecting the base material, reinforcing it and compensating for the flaws (brittleness) of the base material, and when performing processing such as doweling or actual processing on the end surface of the wood, or when nailing during construction. Furthermore, the decorative board, which is made by adhering a decorative veneer to a composite board, has excellent dimensional stability, less occurrence of warping, and is nonflammable because it is inorganic. ,
It has many advantages such as excellent workability, workability, heat insulation, and sound insulation, and there is no risk of contamination of the decorative veneer by the gypsum board and no damage from pests.

In the above embodiment, the side wood chips and the end wood chips are joined by the protrusion provided on the side wood chips and the groove provided on the end wood chips. This does not necessarily have to be the case; for example, a groove may be provided in the connecting portion of the side wood scraps, and a protrusion may be provided in the connecting portion of the end wood scraps to connect the two.

A decorative composite board is formed by laminating the decorative veneer 17 on the upper surface of the composite board obtained in this way so that the end wood of the end wood represents the grain surface of the decorative veneer. A decorative composite board 18 shown in FIG. 7 is obtained by applying decorative processing to the entire side portion of the board.

Examples of decorative processing include tiered decorative processing that combines right-angled cutting and curved cutting as shown in Figure 5, decorative processing that cuts the sides diagonally as shown in Figure 6, and decorative board cutting. It is advisable to apply a desired cosmetic treatment depending on the purpose of use.

In this invention, the wood chips for the end of the wood to be attached to one opposing side of the non-wood base material need to be the wood ends of the wood cut that represents the end surface, but this is achieved by laminating a decorative veneer on the top surface. This is because when decorative processing is applied, if the wood is not a wood scrap with a butt end surface, it will not appear to represent the end grain of a decorative veneer, that is, it will not appear to be solid wood. The side wood scraps attached to the other opposing side of the non-wood base material do not have much effect on making the decorative board look like a single piece of solid wood, so even if it is straight-grained, it is better to use board-grained wood scraps. Depending on the grain pattern of the decorative veneer to be attached to the top surface, you may choose one that emphasizes the solid wood, but it is generally preferable to use straight-grained wood.

It is preferable that the non-wood base material and the wood scraps attached to the four sides of the non-wood base material have approximately the same thickness. Further, depending on the purpose of use, a board material, paper, synthetic resin sheet, etc. may be attached to the side of the composite board of the present invention to which the decorative veneer is not attached.

When attaching a decorative veneer to the other side of a non-wood base material, the size of the decorative veneer should be at least large enough to cover the non-wood base material; There is no advantage as it will be removed immediately.

FIG. 8 shows another embodiment of the composite board of the present invention, in which three gypsum flat boards 10 are connected in a straight line through straight-grain wood scraps 14 for the ends, and the connection direction of the connected object is Straight-grain wood scraps 14 for the butt end are attached to both sides, and wood scraps 11 for the side surfaces are attached to the other both sides of the connected object to obtain a composite board 16' shown in FIG. 8. The stone-covered board and the wood scraps for the end cutter or the wood scraps for the side face are connected via adhesive through the grooves provided on the stone-covered board 10 and the protrusions provided on both wood scraps. has been done.

A decorative veneer 17 is pasted on each of the gypsum boards 10 of the composite board 16' obtained in this way to the extent that the gypsum board 10 is sufficiently covered, and all the wood chips for the end of the end of the wood are removed. A decorative composite board 18' shown in FIG. 9 is obtained by applying decorative processing to the side wood scraps.
is obtained.

In this way, composite boards obtained by connecting non-wood base materials in a straight line or in both vertical and horizontal directions are
I attached a decorative veneer to this and gave it a decorative finish, so
The resulting decorative board has a continuous block appearance. Such a continuous block-like decorative board has the advantage that, especially when used as an interior material for a room, it simplifies construction and is aesthetically superior because no seams are visible.

As mentioned above, the decorative composite board of the present invention uses an extremely small amount of wood, which saves wood resources, and since the decorative veneer is attached to this composite board, it is possible to reduce the amount of wood used. Compared to decorative boards that omit wood, the decorative boards that have been decoratively processed in this way have the advantage of being able to have a desired decorative finish on the sides, and that they look like solid wood in appearance.
