Abstract

(57) [Summary] [Purpose] In order to improve the construction efficiency, a plurality of rectangular bodies provided with fitting parts are shifted in the length direction, and the decorative plates joined at the fitting parts are fitted together during handling. Be careful not to come off in the department. [Structure] A tip portion of a fitting convex portion of a rectangular body is enlarged, a concave portion has a shape corresponding to the convex portion, and the rectangular body is joined by shifting a desired dimension in a length direction.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a structure of a decorative board such as a floor board, a wall board, and a ceiling board.

[0002]

[Prior Art]

 Conventionally, there is a decorative board in which a veneer, a decorative paper, or a synthetic resin sheet is attached to the surface of a wood-based board, and a plurality of rectangular bodies provided with projections and recesses for fitting are offset and joined at the peripheral edge. Provided, this veneer was effective in improving the workability.

However, since the fitting portion of the decorative plate simply joined at the fitting portion comes off during handling, an adhesive is applied to the fitting portion so as not to come off, or after fitting. It has been proposed that the back surface has a sheet-shaped material attached to one surface, or that the wire is stretched and fixed.

[0004]

[Problems to be solved by the device]

 However, when adhesive is applied to the mating part or when a sheet-like material is attached to the back side with adhesive, it takes time to cure and cure the adhesive, while fixing with wires etc. also requires work. There was a problem that the fitting would come off by the time it was completed.

[0005]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned problems, and the structure thereof is a makeup in which a plurality of rectangular bodies having fitting convex portions and concave portions at the peripheral end portion are displaced by a desired dimension and a plurality of them are joined on the long side. In the plate, the problem was solved by providing a decorative plate in which the tip of the fitting convex portion is larger than the base portion and the fitting concave portion is expanded toward the deep portion so as to correspond to the convex portion.

[0006]

[Action]

 In this invention, in the cross section of the decorative plate, the tip of the convex portion for fitting is enlarged, and the concave portion is expanded toward the deep portion so as to correspond to the convex portion, when the rectangular bodies are joined. , So that it does not come off easily.

Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 1 is a plan view of a decorative plate according to an embodiment of the present invention, FIG. 2 is a sectional view taken along the line AA, and FIG. 3 is an enlarged sectional view of an essential part of FIG.

【Example】

 The rectangular body 3 is made of a wood-based board such as plywood, particle board, MDF, LVL, etc., with a veneer, decorative paper, or a decorative sheet such as a synthetic resin sheet attached to the surface, or a solid natural wood material. A fitting portion including a convex portion 1 having a large front end portion 1-A and a concave portion 2 having a shape that expands toward the deep portion so as to correspond to the convex portion 1 is provided. In this case, the convex portion and the concave portion provided on the short side of the rectangular body 3 may have a normal actual shape.

As an example of a method of processing the fitting portion provided at the peripheral end portion, the convex portion is first provided with a normal convex portion using a commonly used cutting tool, and then the base portion of the convex portion is provided on the substrate. Cut along one side or both sides. The concave portion is sequentially cut from the grain of the substrate by using a cutting tool having the same sectional shape as the concave portion to be obtained. Alternatively, after the convex portion and the concave portion are machined by a conventional method, the convex portion is the convex portion whose root is to be cut along one side or the upper and lower sides of the substrate, and the concave portion is the concave portion to be searched. If you cut again using a tool with the same cross-sectional shape, there will be no damage when cutting the recess. The processing need not be limited to this method.

At the edge of the surface, a chamfered portion 5 is provided at the same time when the fitting portion is processed, and when a decorative plate is applied, a groove is formed between the decorative plate and an adjacent decorative plate. In addition, it is advisable to apply grooves 6 to the surface of the decorative plate to emphasize the three-dimensional effect.

Next, using a plurality of the rectangular bodies 3 obtained as described above, the long sides are bonded to each other with the desired dimension shifted in the length direction as shown in FIG. The rectangular body 3 is joined by sliding the fitting part from the opening of the rectangular body 3. At this time, when the convex portion 1 or the concave portion 2 is coated with a rubber-based adhesive having flexibility even after being cured, it is possible to prevent squeaking when used for a floor board or the like.

If a sheet-like material 4 having a cushioning property is attached to one surface of the back surface of the decorative plate to which the rectangular bodies are joined, the unevenness on the surface of the construction portion can be absorbed and the impact can be absorbed. It is also effective for soundproofing.

[0014]

[Effect of the device]

 The decorative plate of the present invention has the above-mentioned configuration so that the fitting portion does not easily come off during handling and the decorative plate does not come apart, and even when a sheet material such as a cushion material is attached to the back surface in the next step. Easy to handle. In addition, since multiple sheets are joined by shifting them, the construction performance is improved.
