Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction material for a building, which enables an inexpensively constructed building and has a high-quality finished building, and more particularly to a floor material and a wall material for a house. In addition to decorative surface materials such as, etc., constructions that can be used in place of those used as building action materials such as high-grade timber or veneer boards for such as upstiles, floor pillars, floor materials, long presses (nagashi). The present invention relates to a material, and a reinforcing decorative material used on the surface of the construction material or furniture.

[0002]

2. Description of the Related Art For construction materials for buildings, muku construction materials such as name trees have been used for a long time, such as entrances and floor sills. Due to the high price and difficulty of obtaining such materials,
Although there were many cases in which a thick plate material was used as a substitute, recently, a projecting plate (attached) is used on the surface, and an integrated material in which a plurality of plates are integrated has been used as an inner core material. Such a technique is often found in patent applications, for example, Shoukai 62-467.
No. 36, JP-A-63-184662, and the like.

The upstiles at the entrances and floors are usually the upper front edge (corner).
Is greatly chamfered. In the case where a veneer is attached to the surface of the integrated material, if the chamfering is performed to a large extent, the core material is exposed, resulting in poor aesthetics. Therefore, for example, in Japanese Utility Model Laid-Open No. 62-46736, as shown in FIG. 8, a corner member fitting groove 21 is provided in an upper front edge of a frame base material 20 made of an integrated material, and a corner member 22 having a chamfered surface is formed therein. And the projecting plates 23 are attached to the upper surface and the front surface of the corner member. In addition, JP-A-63
No. 184662, as shown in FIG. 9, the decorative material 24 having a chamfered surface is fitted to the upper front edge of the frame base material 20, and the veneer 23 is attached to the upper surface and the front surface of the decorative material 24. The material 24 is exposed.

[0004]

The conventional method of making a frame member using such an integrated material as a core material and a projecting plate on the surface thereof requires a measure of biting on the chamfered surface in order to allow the projecting plate to be used. However, this leads to high costs.
In addition, since the corner member 22 and the decorative material 24 are made of different materials from the veneer 23, the seams are conspicuous and unnatural remains. The present inventor considers the use of a thin veneer for the purpose of constructing an inexpensive building, and enables the use of veneer and paper for other building construction materials, furniture, etc. as well as frame materials having a large chamfered surface. I considered it. Therefore, the base, laminate with veneer or paper, that is, synthetic resin having a large adhesive strength of the adhesive coating to the veneer is also examined, and the synthetic resin is used for veneer, wood grain printing paper, wood grain metal foil, or We have made it possible to provide a reinforcing decorative material laminated with a synthetic resin with a wood pattern.

[0005]

DISCLOSURE OF THE INVENTION The present invention uses a veneer, a wood grain printed paper, a wood grain metal foil, or a reinforcing decorative material obtained by laminating a synthetic resin film on a thin material of a wood grain synthetic resin. It is a building construction material that is laminated with the wood material side to the surface of the core material that uses self-extinguishing synthetic resin foam as a part of the integrated material, and the veneer surface is resin finished as necessary. . The veneer is a thin piece of 0.2-0.6 mm name tree, and it is film laminated on both sides or one side depending on the product specifications. The paper that constitutes the wood grain printed paper includes paper in which synthetic fibers are mixed or paper made of synthetic resin, in addition to paper using ordinary pulp. The wood grain pattern metal foil is, for example, an aluminum foil or a copper foil printed with a wood grain pattern. The wood grain synthetic resin does not emit toxic gas in the case of fire, that is, it does not contain halogen, especially polyvinyl chloride. The wood material is plywood or timber and has a diameter of about 2 mm. Plywood is preferable in terms of price.

The synthetic resin film used here is polyurethane, ethylene-vinyl acetate copolymer, polyamide,
Polyester, polyacrylic acid ester, polypropylene and the like are preferable, but carboxylic acid-modified polyethylene is most preferable from the viewpoint of adhesive strength to the veneer. This is the introduction of a carboxyl group into polyethylene with many branched chains.
(Hereinafter, when the synthetic resin film is referred to in the present invention, carboxylic acid-modified polyethylene is most preferable). As a method of introducing the carboxyl group, for example, maleic acid is added to the terminal unsaturated group of polyethylene having many branched chains by graft polymerization.

The synthetic resin film is preferably laminated on a veneer, a metal foil of a wood grain pattern, or a thin material of a wood grain pattern synthetic resin from a molten resin by a T-die method or the like immediately after being formed, but it is formed beforehand as a film. You may heat-melt and laminate what is carried out. INDUSTRIAL APPLICABILITY The present invention can be provided to the general market only with a reinforcing decorative material obtained by laminating a synthetic resin film to a thin material of this veneer, wood grain printed paper, wood grain metallic foil, or wood grain synthetic resin, and various fabrication materials. It should be used on surfaces such as furniture and furniture.

The self-extinguishing synthetic resin foam is a foam made of polystyrene, polyethylene, urethane or the like, to which a known flame retardant or fire extinguishing agent is added in order to enable self-extinguishing. . It does not necessarily have to be a noncombustible material as long as it has self-extinguishing performance.

According to the present invention, a reinforcing decorative material obtained by laminating a synthetic resin film on at least one side of a veneer, a wood grain printed paper, a wood grain metal foil, or a thin wood grain synthetic resin material is laminated with a wood material to form a wood material. Provide a double V-cut part that is cut into two parallel V-shaped grooves on the side, and glue the wood side to the integrated material so that the double V-cut part is located in the chamfered part that cuts the corner of the integrated material. It is a construction material for buildings that will be used as a frame material. The double V-cut section has a 45 ° kerf on the wood material side as the best cut by a cutter, and two 45 ° kerfs are provided at a predetermined interval (width of chamfer). The V-cut part becomes a right angle (90 °) when bent.

The present invention is also a reinforcing decorative material obtained by laminating a synthetic resin film on at least one surface of a veneer, a wood grain printed paper, a wood grain metal foil, or a thin material of a wood grain synthetic resin. This reinforcing decorative material gives the aesthetics and warmth (comfort) peculiar to wood by being attached to the surface of other members. The laminate layer helps prevent cracking of the veneer and increases the strength of the V-cut thin portion, and it can be attached to various building features with the same shape to make it look like muku wood. The manufacture of such a veneer reinforcing material for a veneer has conventionally been difficult because it is difficult to obtain an endless veneer, that is, a long product. Since the veneer plate can be manufactured as an endless product and can be wound up, it is possible to laminate the veneer by the T-die method.

The present invention also provides a structural material for buildings in which the periphery is wood for core materials such as plywood and veneer core plywood, and the inside is a composite core material of self-extinguishing synthetic resin foam. This composite core material enables inexpensive manufacturing, and also has the effects of flame retardancy and weight reduction.

Further, the present invention is a building material for buildings, which is formed by laminating the above-mentioned reinforcing decorative material on the surface of a wooden material as a surface decorative board to form a decorative plywood. Even if the veneer is thinner than the conventional decorative plywood, it is possible to obtain a high-grade decorative board with great durability and little cracking.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION This reinforcing decorative material is attached to a wood material, and this is attached to the surface of a core material using a self-extinguishing synthetic resin foam instead of the wood material as a part of the integrated material, A resin finish (if necessary in the case of double-sided laminating) gives a building appearance material that looks like wood and has an inexpensive interior and self-extinguishing properties.

In particular, in the structure having a double V-cut portion formed by cutting two V-shaped grooves parallel to the wood material at the corner of the integrated material, even if the corner is chamfered greatly,
Since the reinforcing decorative material is closely attached to the chamfered portion, a large chamfered portion can be formed without using another wood member for chamfering, which is suitable for a door or floor frame. V
If the cut portion is 45 ° and two chamfered portions are formed at a distance that covers the width of the chamfered portion, the chamfered portion is well formed at the corner of the square timber, resulting in a high-grade frame material.

A veneer, a metal foil with a wood grain pattern, or a synthetic resin film laminated with a synthetic resin film of a wood grain pattern is used as a reinforcing decorative material so that the veneer has sufficient strength even if the veneer is thin (0.2 to 0.6 mm). In addition, it has the flexibility to follow the adhesion partner well. It can also be used as wallpaper instead of a luxury cloth. In addition, it can be used as a high-quality decorative board by using it on the surface of cheap conifers or veneer core plywood,
Further, by covering the outer circumference of a pulp fiber board, a gypsum board or the like, it can be used as a high-grade wood for a frame material or a door material.
