By the way, when forming a wooden substrate or a steel substrate, no matter how careful the worker is when assembling, the pillar member may not properly face the front and may be inclined or slightly protruded. Often withdrawn. Therefore, when the above decorative plate is continuously attached to such a base, there is a problem that a linear step is formed at the joint portion between the decorative plates located on the pillar member. If there is such a step on the wall surface after interior decoration, the cut end surface of the decorative plate can be seen, and when light or sunlight is inserted from an oblique direction, the shadow or shadow may appear at the step and the connection may occur. It caused a situation where parts were very noticeable.

The present invention has been made in view of the above-mentioned problems, and an object thereof is to prevent a step from being formed at the joint portion regardless of whether the planar state of the base is good or bad. It is to provide a decorative board that can be used for interior decoration.

[0005]

In order to achieve the above object, the present invention is a decorative plate having a decorative sheet on the front side of a rectangular substrate, wherein one side edge serving as a joining edge has a front side. A groove in the length direction is provided so as to form a protrusion and a back side protrusion protruding from this, and
On the other side edge serving as the joining edge, a longitudinal ridge that can be fitted into the groove is provided at the same height as the groove so as to form a front step and a back step deeper than this. The size of each ledge and each step is that of the front ledge with a gap left between the back ledge and the back tier when the ridge of the adjacent veneer is inserted into the groove in one veneer. The tip portion and the rising portion of the front side step portion are in contact with each other, and a plurality of nail holes of a size in which the head of the nail is loosely fitted are formed at predetermined intervals in the length direction on the front side of the back side protrusion. It is characterized by

[0006]

The decorative plate having the above-mentioned structure is continuously attached to the base by inserting the protrusion on the other side edge of the next decorative plate into the groove on one side edge of the previously installed decorative plate. It is attached. In this case, since the groove and the ridge are at the same height,
The surface of the decorative plate does not become flat and steps are not generated.
In addition, nails are nailed in the nail holes on the back side protruding on one side edge of the decorative plate to fix one side of each decorative plate to the base, but by driving so that the nail head enters the nail hole, the next makeup The nail does not get in the way when the ridge of the board is fitted into the groove of the decorative board. In addition, by nailing nails into the nail holes and fixing one side of the decorative plate, it is prevented that the decorative plate is fixed along the pillar member that is tilted or bent, the surface is finished flat and the groove of the ridge is finished. Can be easily inserted.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a partial cross-sectional view in the width direction showing a decorative plate as one embodiment of the present invention.

The decorative plate 1 has a decorative sheet 3 on the front side of a rectangular substrate 2, which is continuously adhered to a base with left and right side edges shown in the drawing as joining edges, and The side edge is provided with a longitudinal groove 6 so as to form a front side protrusion 4 and a back side protrusion 5 protruding therefrom, and the other side edge is provided with a longitudinal protrusion capable of being fitted into the groove 6. The strip 7 is provided at the same height as the groove 6 so as to form the front side step portion 8 and the back side step portion 9 deeper than the front side step portion 8.
The size of each protrusion 4, 5 and each step 8, 9 is 1.
When the protrusions 7 of the adjacent decorative plate 1 are fitted into the grooves 6 of the two decorative plates 1, the tip portion 4a of the front side protrusion 4 and the front side step are left with a gap left between the back side protrusion 5 and the back side step portion 9. The rising portion 8a of the portion 8 comes into contact. Further, a plurality of nail holes 10 each having a size into which a nail head can be inserted are formed in the front side of the back side protrusion 5 at predetermined intervals in the length direction (direction perpendicular to the paper surface).

The decorative plate 1 having the joint end face as described above is
A decorative sheet made by laminating a decorative sheet 3 on a base material 2 such as a plywood board, a gypsum board, a calcium silicate board, and a rock wool board. The side edges on both sides, which are the joint edges, are cut into the above shapes. After processing, it can be created by hollowing out a concave portion to be the nail hole 10 in the back side protrusion 5.

The decorative plate 1 can be made of cardboard by the following procedure. That is, as shown in FIG. 2, three corrugated cardboard sheets 11a to 11c cut into a predetermined size are used, and these are bonded with an adhesive as shown in FIG. Groove 6 is provided, and the ridge 7 in the longitudinal direction is provided on the other side edge.
Is formed. In this case, the front side protrusion 4 and the back side protrusion 5 protruding from this are formed above and below the groove 6, and the front side step portion 8 and the back side step portion 9 deeper than this are formed above and below the protrusion 7, respectively. The sizes of the corrugated cardboard sheets 11a to 11c are determined in advance. By forming the decorative plate 1 by laminating in this manner, it is possible to finish neatly without the need for cutting the joint edge, and as a result, the fitting can be easily performed. The decorative board 1 created as described above has the corrugated cardboard sheets 11a to 1
Since there is the adhesive between 1c, when the protrusion 7 of the adjacent decorative plate 1 is fitted into the groove 6 of one decorative plate 1, a gap corresponding to the thickness of the adhesive is formed. Therefore, the gap is eliminated by applying an adhesive agent to the surface of the back side protrusion 5 at an appropriate interval.

The decorative sheet 3 may be attached to the front corrugated cardboard sheet 11a in advance, or the three corrugated cardboard sheets 11a to 11c may be adhered to each other, or the front side corrugated cardboard sheet 11a may be laminated. Alternatively, the corrugated board sheet 11a and the central corrugated board sheet 11b may be bonded together. Further, the concave portion 10 to be the nail hole 10 may be provided in advance on the back side corrugated board sheet 11c, or may be hollowed out after the three corrugated board sheets 11a to 11c are bonded.

Here, the corrugated cardboard sheets 11a to 11c are used.
As the material, those subjected to appropriate flame retardation treatment, curing treatment, water resistance treatment, etc. may be used. The decorative board 1 produced using such a corrugated cardboard sheet has fire resistance, water resistance, and the like, and is strong, lightweight, and inexpensive.

When the decorative board 1 is made of corrugated board, as shown in FIG. 4, four corrugated board sheets 12a to 12d cut into a predetermined size may be bonded together as shown in FIG. In this case, the nail hole 10 can be formed by previously providing the second corrugated cardboard sheet 12c from the back side in a penetrating state. Of course, four cardboard sheets 12a
After gluing ~ 12d, the concave portion which becomes the nail hole 10 may be hollowed out.

The number of corrugated cardboard sheets to be bonded is not limited to the above-mentioned three or four, and
As long as the joint edge having the above-mentioned shape can be finally formed, the number of sheets to be bonded is arbitrary. Further, the thickness of each corrugated cardboard sheet to be bonded is arbitrary and may be appropriately determined in consideration of strength and the like.

When the interior of the wall surface is made using the above decorative plate 1, a plurality of decorative plates 1 are prepared, and these are continuously attached to a base assembled at the same intervals as the width of the decorative plate 1. . In this case, as shown in FIG. 6, the above decorative plate 1A is in a state in which a nail N is hit in the nail hole 10 of the back side protrusion 5 and the joint side thereof is fixed to the base pillar member P. In the groove 6 of the preceding decorative plate 1A, the next decorative plate 1
The ridge 7 of B is fitted and joined in the state shown in FIG. 7, and the next decorative plate 1B is fixed by similarly nailing the joining side on the opposite side.

When fixing the joint side of the decorative plate 1A with the nail N, the nail N is driven until the head of the nail N enters the nail hole 10 of the back protrusion 5. By nailing in this way, the head of the nail N is hidden in the nail hole 10, and the ridge 7 of the next decorative plate 1B is formed.
Is not caught on the head of the nail N, and the groove 6 of the above decorative plate 1A
Be inserted into. Further, since the head of the nail N is loosely fitted in the nail hole 10 and the decorative plate 1A is stopped at the bottom portion of the nail hole 10, the decorative plate 1A is a pillar even if the pillar member P is tilted or bent. The member P is fixed while keeping its planar state without following the surface of the member P. Therefore, the groove 6 of the above decorative plate 1A
On the other hand, it is not difficult to fit the ridge 7 of the next decorative plate 1B. It should be noted that the nail N may be attached to the pillar member P only, but an adhesive agent may be used together to ensure the fixation. Further, if the adhesive is applied to the nail hole 10 after the nail N is hit, the rattling of the decorative plate can be reliably prevented. Needless to say, as the decorative plate located at the end of the wall surface, a straight plate without the side edge as described above is used on one side.

When the decorative plate 1 is continuously attached to the base as described above, the tip portion 4a of the front protrusion 4 of the previous decorative plate 1A and the front step 8 of the next decorative plate 1B.
The rising portions 8a of the sheet are in contact with each other, and the edges of the decorative sheet 3 are abutted against each other at the same height, so that the seam is inconspicuous.

The tip portion 4a of the front side protrusion 4 and the rising portion 8a of the front side step portion 8 may be vertical, but as shown in the figure, one or both of them are inclined surfaces. preferable. By doing so, the edges of the decorative sheet 3 are pressed against each other to be in a compressed state, so that the seam becomes less noticeable.

[0020]

As described above, according to the decorative plate of the present invention, the ridge on the side edge of the next decorative plate is inserted into the groove on the side edge of the previously installed decorative plate. Since the groove and the ridge are at the same height when continuously attached to the base, it is possible to carry out interior decoration without causing a step on the surface of the decorative plate.

Also, by providing a nail hole of a size that allows the head of the nail to be loosely fitted on the front side of the back side protrusion at the side edge of the decorative plate, the ridge of the next decorative plate is inserted in the groove of the preceding decorative plate. The nail can be smoothly inserted without disturbing the insertion. In addition, since one side of the decorative plate is fixed by hitting a nail into the nail hole, it is possible to prevent the decorative plate from being fixed along the pillar member that is tilted or bent, so that it is a flat surface regardless of whether the ground condition is good or bad. Each decorative plate can be attached to the base while maintaining the state, and the ridge of the next decorative plate can be easily fitted into the groove of the preceding decorative plate.
