[0007]

The present invention will be described below based on three embodiments with reference to the drawings. In these examples, the same members are designated by the same reference numerals.

Embodiment 1 (see FIGS. 1 to 4) In this Embodiment 1, the front means the front side of FIG.
The rear means the back side, the left means the left side in FIG. 1, and the right means the right side in the figure.

First, the decorative plate 1 manufactured by the method of Example 1 will be described. The decorative plate 1 includes a core plate 3 made of particle board or the like (the width is about 800 mm and the height is about 2000 mm), and covers the right side surface, the front surface, the left side surface, and the rear surface of the core plate 3. It has a decorative sheet 4 attached to and a decorative edge member 5 attached to the upper and lower surfaces of the core plate 3.

The core plate 3 includes a right end member 3a and a front member 3
b, the left end member 3c and the rear member 3d. The right end member 3a, the front member 3b, the left end member 3c, the rear member 3d
Are mutually divided as shown in FIG. A moisture-proof sheet 6 made of synthetic resin impregnated paper or the like is interposed between the front member 3b and the rear member 3d. With such a configuration, that is, the core sheet 3 is covered with the decorative sheet 4 to prevent or suppress the movement of water between the core sheet 3 and the outside, and the moisture-proof sheet 6 is provided between the front member 3b and the rear member 3d. The movement of water is blocked, that is, since the water content of the core plate 3 is not extremely biased, the warp can be suppressed. The main cause of water movement between the front member 3b and the rear member 3d is a temperature difference before and after the decorative plate 1, for example, the front side of the decorative plate 1 faces the outside and the rear side faces the inside. In some cases, there is a temperature difference. The front member 3b
On the rear surface and the front surface of the rear member 3d, required vertical grooves 8 that are in a state of abutting each other with or without the moisture-proof sheet 6 interposed therebetween are formed at predetermined intervals in the vertical direction. Due to the presence of these grooves 8, the front member 3b and the rear member 3
The contact area with d decreases and the front member 3b and the rear member 3d
Since the propagation of sound between and is suppressed, the soundproofing performance can be improved.

The decorative sheet 4 is composed of a synthetic resin sheet such as vinyl chloride, a veneer reinforced with a backing sheet such as Japanese paper or a non-woven fabric, and a decorative paper. The coating film is covered. The decorative sheet 4 is a single sheet, and one end A and the other end B thereof have a rear end angle of the right end member 3a (in other words, the rear member 3d).
(The right corner of) is facing each other. That is, the decorative sheet 4 surrounds the right end member 3a, the front member 3b, the left end member 3c, and the rear member 3d in this order. As is clear from this description, the right end member 3a, the front member 3b,
Since the left end member 3c and the rear member 3d are attached to the single decorative sheet 4, if only the surfaces of the right end member 3a and the rear member 3d that face each other are adhered, the other portions may not be adhered. , The right end member 3a, the front member 3b, the left end member 3c, and the rear member 3d are integrated. Of course, it goes without saying that the right end member 3a, the front member 3b, the left end member 3c, the rear member 3d, and the moisture-proof sheet 6 which are adjacent to each other may be bonded together.

A decorative molding 9 assembled in a frame shape is attached to the front decorative sheet 4 and the rear decorative sheet 4. Since these decorative moldings 9 have a cross-sectional shape that is high on the outside and low on the inside, the center part surrounded by the decoration moldings 9 looks down (dented), and as a result, a design with unevenness and rich variation. It can be used as the decorative plate 1. On the other hand, as shown by the alternate long and short dash line in FIG. 2 and FIG.
If the cross-sectional shape is low on the outside and high on the inside, the center part surrounded by the decoration molding 9 looks up (protruding), and as a result, the periphery looks relatively low and rich in unevenness. It can be used as a decorative plate 1.

A vinyl chloride sheet, a veneer coated with a top coat, a decorative paper or the like is used as the decorative edge member 5.
