を有している。Various decorative board materials are used as furniture covering materials, housing interior materials, etc., but all of them are flat plate-like and are unsuitable for attachment to furniture, wall ridges, etc. For this reason, conventionally,
The back side of a precious wood veneer is laminated with 9 pieces of non-woven paper, etc., to create a decorative board material that can be bent. However, even with this type of decorative board material, cracks may occur on the decorative surface as a result of bending, and when bending at right angles, etc., the decorative board material must be wetted to give it plasticity before processing. However, as a result, it has the disadvantage that stains etc. occur on the surface of the chemical solution.

成したものである。In view of the above-mentioned circumstances, the present invention aims to provide a decorative board material that does not require wet treatment even when bent at right angles, is beautiful in an air-dry state, and is capable of LIF bending without cracking. The purpose is to use foam rubber, soft polyvinyl chloride, soft polyethylene, synthetic rubber, natural rubber, and urethane foam between the base material such as plywood/fiberboard, insulation board, particle board, etc., and the surface precious wood veneer. After bonding and integrating a sheet material having rubber elasticity such as the above, a tapered groove portion reaching the sheet material from the base material side is formed.
以下、本発明を添付図面に基づき説明する。Hereinafter, the present invention will be explained based on the accompanying drawings.

いないもののいずれでもよい。The illustrated decorative board material is formed by interposing an elastic sheet material 3 between a base material 1 and a surface precious wood veneer 2, and laminating them together with an adhesive 4 (see Fig. 1).6 base materials 1. plywood, fiberboard, insulation board, particle hoard, etc. can be used, and the surface is made of precious wood veneer 2
The material may have a nonwoven fabric attached to the back surface or may not have a nonwoven fabric attached to the back surface.

のが好ましい。As the elastic sheet A3, a sheet material having so-called "rubber elasticity" such as foam rubber, soft polyethylene, synthetic rubber, natural rubber, or urethane foam material is used. As the adhesive 4 used to bond the elastic sheet material 3 to the base material 1 and the surface precious wood veneer 2, a soft and tenacious adhesive such as diene, acrylic, or urethane adhesive may be used. is preferred.

A tapered groove 5 having a substantially trapezoidal to V-shaped cross section is formed (see FIGS. 2 and 3).

を得ることができる。The decorative board material constructed as described above is coated with an appropriate adhesive on its back surface, bent around the tapered groove 5, and then adhered to a ridgeline portion 6 of furniture, a concrete inner wall, or the like. At this time, the surface precious wood veneer 2 of the decorative board material has a length that can be bent into a circular arc shape due to the elastic action of the elastic sheet material 3, and does not undergo angular deformation (see FIGS. 4 and 5). Therefore, even when right-angle bending is required, the surface precious wood veneer 2 will not suffer from cracks or hangnails, and since the bending can be done in an air-dry state, there will be no surface contamination due to wet processing, resulting in a beautiful finished appearance. Obtainable.

Next, a diene adhesive is applied and allowed to dry to the touch, after which precious wood veneers with non-woven fabric already pasted on the surface are laminated. After this laminate is pressed and integrated at room temperature, a trapezoidal taper groove is cut. This laminated material with tapered grooves cut is pasted with a urethane adhesive while bending the prismatic surface of the laminated wood, and is pressed together at room temperature. The surface of the obtained pillar material is
