Description

{Circle over (1)} The present invention relates to a decorative veneer for a building, and more particularly to a decorative veneer provided for a decorative flooring and a decorative flooring material formed by combining them.

木 In many cases, wooden floors are formed in ordinary houses and condominiums by laying strip-shaped floor pieces having a grain on the surface on a floor structure. Since the above-mentioned floor piece is very expensive if it is entirely made of a rubber material, it is usually formed of a decorative floor plate in which a veneer (decorative veneer) is adhered to the surface of a plywood or the like.

The decorative floorboard of this type has its upper edge cut diagonally, and when laid, a groove having a V-shaped cross section is formed between adjacent decorative floorboards (see Patent Document 1). .
Japanese Utility Model Application Laid-Open No. 2-223131

However, in the case where the V-shaped groove is formed between the adjacent decorative floorboards as described above, a floor having a rich three-dimensional feeling and a soft taste cannot be formed, and the presence of the corners of the upper edge of the floorboards makes walking difficult. Was bad.

In order to make the above three-dimensional effect larger, it is conceivable to make the groove deeper, but if the floorboard is cut deeply to make the groove deeper, it will be cut deeply to the plywood under the wood board, and that part will be At the bottom of the groove, it was noticeable black and the design was impaired. It is conceivable to use a thick plate as a wood plate so that the cut does not reach the plywood deeply, but in that case, the cost is high, and forming the groove too deeply further reduces the walking feeling It became.

The present invention has been made in view of the above points, and an object of the present invention is to provide a decorative veneer suitable for use as a decorative floorboard having excellent design and walking properties.

The decorative veneer of the present invention has a decorative veneer on which a decorative veneer is stuck on a wooden substrate so that the decorative veneer extends from the veneer veneer to the upper layer of the wooden substrate along its upper edge, and is perpendicular to the veneer. The cross-sectional shape is cut out so as to form a curved surface shape protruding outward, and the curved surface shape is close to a horizontally long elliptical shape.

According to the decorative panel for construction of the present invention, the decorative panel is cut off at the upper edge so that the vertical cross section has a curved surface shape protruding outward, and the curved surface shape is close to a horizontally long elliptical shape. There is a three-dimensional appearance, and the ratio of the width of the wood substrate portion exposed to the cut portion in the planar shape to the entire cut width is small, so that a decorative veneer for the wood substrate portion that is hard to see is obtained, and the curved shape portion in the planar configuration Has a large width in a plane, the three-dimensional appearance with a soft taste is increased, and the wood substrate portion is further less noticeable. In addition, since the vertical cross-sectional shape of the upper edge of the decorative veneer is close to a horizontally long elliptical shape, the curved surface shape connected to the upper surface at the upper edge of the decorative veneer is gentle, so that the upper surface of the decorative veneer is flat. When viewed visually (when a resident walking on the floor looks at the decorative panel from above), it can be seen widely, and the tread surface has a wide upper surface, so that the design is good and the feeling when stepping on is also good.

According to the decorative veneer of the present invention, an architectural decorative material suitable for floorboards and wallboards, which has a three-dimensional effect and has excellent design in which the wooden substrate portion is hardly noticeable on the cut surface, can be obtained. In particular, as described above, the wood substrate under the decorative veneer is made inconspicuous, so that a thin veneer can be used as a decorative veneer. For use in decorative panels. In addition, a soft decorative three-dimensional appearance is enhanced, and a decorative veneer suitable for floorboards and wallboards, which is excellent in design and makes the wood substrate portion more invisible on the cut surface, can be obtained at low cost.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows an end face configuration of the decorative flooring material of the present invention, and FIG. 2 shows an enlarged configuration of a main part thereof. The decorative flooring 1 is configured by arranging a plurality of strip-shaped decorative flooring boards (building decorative boards) 3 on a base material 2 such that the longitudinal directions thereof are adjacent to each other and the ends thereof are abutted. . As the base material 2, a plywood, a particle board, a medium fiber board or the like is usually used.

The decorative floorboard 3 is composed of a decorative veneer (wooden substrate) 5 having a decorative veneer (0.6 mm thick) 6 adhered on a plywood (woody substrate) 5. The veneer was cut so as to extend from the veneer 6 to the intermediate height of the deck (1.2 mm thick) 8 located in the upper layer of the plywood 5 and to have a curved surface shape R whose vertical cross-sectional shape protruded outward. It is configured. Instead of the plywood 5, a particle board, a medium fiber board, or the like may be used.

Cross-section of the curved shape R, as shown in FIGS. 1 and 2, close to the oblong elliptical shape, are designed to rising angle A ₁ is greater than the rising angle A ₂ in the upper part of the lower portion thereof.

The curved surface shape R may be formed by cutting directly with a cutter 10 having the curved surface shape R as shown in FIG. 3, or after being cut obliquely by a linear cutter 11 as shown in FIG. The polishing may be performed by polishing with a mold 12, and further, as illustrated in FIG.

Prior to wiping painting, the deck 8 surface exposed by the excision is applied with a sanding sealer, enamel or the like that is the same color as the excision surface of the decorative veneer 6 by brush, spray or roll, or the like. The surface is subjected to transfer printing or a decorative sheet attached to the surface, so that the deck 8 is hardly visible.

Then, the decorative floor 3, the configuration having a curved shape R characterized by the rising angle as described above, will have a curved shape R moiety is a width W ₁ in a plan view in its planar configuration, thereby decorative floor Even if the groove M formed as the material 1 is not so deep, a soft three-dimensional effect can be obtained, and since there is no corner at the upper edge a, the walking feeling is also good.

Furthermore, the ratio of the width W ₂ between the side edges b in the plane position of the deck 8 to be exposed becomes very small relative to the overall width W _1, almost by surface treatment is applied to the portion which became the small The deck 8 is configured to be invisible to enhance the design. The ratio W ₁ / W ₂ of W ₁ and W ₂ is preferably “3” or more, and especially when it is “5” or more, the design is further improved. Incidentally, it exposed width W ₂ of the deck 8 is different from the upper edge a width W ₃ of the deck 8 which is exposed in the case of only diagonally cut in a conventional, are significantly reduced.

Further, since the width W ₂ of the deck 8 which is exposed as described above is configured not to touch the eyes, since ablation depth of the upper edge is allowed to extend to the deck 8, the thin as decorative veneer 6 As a result, the decorative floor board 3 and the decorative floor material 1 having a three-dimensional effect and excellent design without increasing the cost can be obtained.

Although the decorative floor material has been described in the above embodiment, even if the decorative panel for construction of the present invention is used as a wall material or the like, a sufficiently excellent design can be obtained. The formation of the curved surface shape may be performed over the entire circumference or may be limited to an appropriate side.

Further, in the above embodiment, as the decorative floor material, a decorative floor plate is mounted on a base material, but a direct-attached type in which the base material is not used may be used. Will be described with reference to FIGS.

FIG. 6 shows a plan view of the decorative flooring material 20. As shown in FIG. 7, the decorative flooring material 20 is provided on a base material 21 made of an independent foamed resin sheet such as polyethylene or polyurethane or a fiber mat. The floorboard 22 is joined and fixed. The joint fixing of the decorative floorboards 22 is performed by fitting a male ridge 24 protruding from a side edge of one decorative floorboard 22 with a female ridge 26 formed by recessing the opposite side edge of the other decorative floorboard 22. This is performed by filling the lower portion with the hot melt resin 27, and with such a configuration, the joint portions of the decorative floor boards 22 can be provided with flexibility. And the obtained decorative flooring 20 as a whole has a buckle 30 continuous with the step-shaped side edge on one side and the side edge in the longitudinal direction on one side, and the step-shaped side edge on the other side and the other side. The female knurls 31 are respectively provided continuously with the side edges in the longitudinal direction of the side, and are configured to be able to be joined and used with other decorative floor boards 20.
