[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative panel which can be easily fixed to the surface of a base material while absorbing irregularities on the surface of the base material and construction errors when the decorative panels are arranged side by side.

[0002]

2. Description of the Related Art A back plate is attached to the back of a square decorative plate,
As a decorative panel having fixed back pieces projecting from the side edge of the decorative board on the back plate material at required intervals, for example, a decorative panel with a flat surface
Japanese Unexamined Patent Publication No. 121529 discloses a technique disclosed. In the decorative panel, the back surface of the fixed protruding piece is formed smoothly, and between the fixed protruding pieces, a recess capable of closely fitting the fixed protruding piece is provided by being receded from a side edge of the decorative board. Had been.

[0003]

However, for example, when a decorative wall surface is formed using such a decorative panel, there are the following problems. It is normal that a certain degree of irregularity exists on the surface of a base material formed by using the rim or on the surface of a flat base material formed by stretching plywood. Therefore, when the decorative panels are arranged side by side on the surface of the base material, irregularities on the surface of the base material appear as they are on the decorative wall surface, and there is a problem that a smooth decorative wall surface with good appearance cannot be formed.

Further, when fitting the fixing protrusion of the decorative panel adjacent to the concave portion of the decorative panel already fixed, the inlet of the concave portion has a wall thickness of the fixing protrusion due to unevenness of the surface of the base material. In some cases, there is a problem that fitting is difficult.

In addition, since the concave portion is formed to have a dimension that allows the fixed protrusion to be fitted in a close contact state, it may be difficult to set the positional relationship between the panels as required due to a construction error when the decorative panels are juxtaposed. There was a risk that the joints on the decorative wall would be uneven.

The present invention has been developed in view of the above problems, and has as its object to provide a decorative panel capable of efficiently forming a smooth decorative surface (wall surface, etc.) regardless of the unevenness of the surface of the base material. Is what you do.

[0007]

In order to solve the above problems, the present invention employs the following means. That is, the decorative panel 1 according to the present invention is a decorative panel which is fixedly arranged on the surface of the base material, and a reinforcing plate 3 having the same outer dimensions as the decorative panel 2 is attached to the back surface of the rectangular decorative plate 2 and the reinforcing plate. A metal plate 5 is adhered to the back surface of 3. At each side edge portion of the metal plate 5, a plurality of fixing protrusions 7 fixed to the surface of the base material are provided at required intervals so as to protrude outward from the side edges 6 of the decorative plate 2. A metal plate is cut out between the adjacent fixed protrusions to form a recess 10 which is located retreated from the side edge 6 and has the back surface of the reinforcing plate as a bottom surface 9. Can be fitted. The length of the concave portion 9 along the side edge of the decorative plate is set to have a sufficient size such that the fitted fixed projection 7 can move in the length direction of the side edge. A screw hole 11 is provided in the fixed protrusion 7, and the back surface of the fixed protrusion 7 can be brought into contact with the surface of the base material so as to cover at least a peripheral portion of the screw hole 11 and is elastically compressed. The adjustment piece 12 having the property is attached. The adjusting piece 12 is preferably formed using a foam material.

[0008]

In the present invention, since the compressibility adjusting piece is adhered to the back surface of the fixing projection, when compressing the decorative panel, the compression amount of the adjusting piece is adjusted to make the surface of the base material uneven. By fixing the fixing protrusions to the surface of the base material while absorbing the water, a smooth decorative surface (wall surface, etc.) can be formed regardless of the unevenness of the surface of the base material.

When fixing another decorative panel on the surface of the base material adjacent to the fixed decorative panel,
When the fixing protrusion of the adjacent decorative panel is inserted into the concave portion on the back side of the base decorative panel, an appropriate compressive deformation occurs in the adjustment piece on the back side of the fixing protrusion of the adjacent decorative panel. The unevenness of the surface of the base material is absorbed by the compressive deformation of the adjusting piece, so that the required level of the side edge of the basic decorative panel and the side edge of the decorative panel adjacent thereto can be obtained at once. That is, favorable unevenness adjustment of both adjacent decorative panels is easily and satisfactorily obtained by being restricted by the basic decorative panel.

[0010] In the present invention, the decorative panels are connected to each other in a state in which the fixing projections having the adjusting pieces of the one decorative panel are inserted into the recesses of the other decorative panel (the decorative panel). Since the panels are related to each other), even if an external force acts on the formed decorative panel surface, the level of the boundary between adjacent decorative panels is unlikely to shift.

When the decorative panel is newly fixed adjacent to the decorative panel in which the adjusting piece 12 is compressed and fixed, the inlet to the concave portion 10 (between the base material surface 13 and the concave bottom surface 9). Since the gap size of the opening end 19 of the groove formed in the recess is reduced by the amount of compression of the adjustment piece, if the fixed projection 7 is difficult to fit into the recess 10 in the state as it is, the following is performed. Do so. That is, as shown in FIG. 7, for example, the fixed protruding piece 7 is slightly inclined and its tip is applied to the introduction port 19, and then the fixed protruding piece 7 is removed while the decorative panel is along the base material surface 13. When the adjustment piece 12 is inserted into the concave portion 10, the fixed protruding piece 7 can be fitted into the concave portion 10 without difficulty, while moderate compression deformation or partial destruction occurs in the adjustment piece 12.

If an error occurs when the decorative panels are arranged side by side, the positional relationship of the decorative panel to be fixed with respect to the already fixed decorative panel is adjusted by the clearance allowing the fixing piece 7 to move in the recess 10. Because you can
The decorative panels can be smoothly arranged in the required arrangement.

[0013]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. 1 and 2, a decorative panel 1 according to the present invention includes a reinforcing plate 3 having the same external dimensions as a rectangular decorative plate 2 on the back surface thereof.
And a metal plate 5 is adhered to the back surface of the reinforcing plate 3.

The decorative plate 2 is formed of a thin plate of a stone material such as marble or granite, or a thin plate of artificial marble or tile. The reinforcing plate 3 is made of, for example, a non-combustible plate such as a silicon plate, and reinforces the decorative plate 2. The metal plate 5 is formed using, for example, an aluminum plate. On each side edge portion of the metal plate 5, a plurality of trapezoidal fixing protrusions 7 having substantially the same external dimensions are provided at required intervals so as to protrude outward from the side edges 6 of the decorative plate 2. I have. A metal plate is cut out between the adjacent fixed projections, and the metal plate is recessed from the side edge 6 and has, for example, a trapezoidal concave portion 10 having a back surface 9 as a back surface of the reinforcing plate. The fixed projection 7 can be fitted. The length of the concave portion 10 along the side edge 6 of the decorative plate is set to have a sufficient dimension so that the inserted fixed protruding piece 7 can move within a required range in the length direction of the side edge. A screw hole 11 is provided in the fixed protrusion 7, and a rectangular plate made of an elastic compressible foam material is provided on the back surface of the fixed protrusion 7 so as to cover the screw hole 11 and a peripheral portion thereof. Adjustment piece 12
Is attached. As the foaming material, a non-combustible calcium carbonate foaming material, for example, Rock Cell Board (trade name) manufactured by Fuji Chemical Industry Co., Ltd. can be used, and a foaming rubber material can also be used.

FIGS. 3 to 5 show a case where such a decorative panel 1 is juxtaposed to a planar base material surface 13 formed by sticking plywood, for example, to form a decorative wall surface. The reference line is appropriately printed, and the decorative panel 1 is sequentially fixed while the fixing protrusion 7 is fitted into the concave portion 10. At this time, the screwing amount of the screw 15 inserted into the screw hole 11 is adjusted,
The unevenness of the base material surface 13 is absorbed in accordance with the amount of compression of the adjustment piece 12, and the fixing protruding piece 7 is screw-fixed to the base material surface.
Thereby, it is possible to form the smooth decorative wall surface 16 regardless of the unevenness of the surface of the base material. In addition, even if a construction error occurs when the decorative panels are arranged side by side, as shown in FIG. 6, since the fixing projection 7 has enough space to move in the length direction F in the concave portion 10, it is necessary to newly fix it. It is possible to adjust the positional relationship of the decorative panels with respect to the already fixed decorative panels, and accordingly, it is possible to form the joint portions 17 appropriately and smoothly arrange the decorative panels in a required arrangement. When a new decorative panel is fixed next to the decorative panel in which the adjustment piece 12 is fixed in a compressed state, the inlet to the concave portion 10 (the base material surface 13 and the concave bottom surface 9
Since the gap size of the opening end (19) of the groove formed between them is smaller by the amount of compression of the adjustment piece, the fixed projection 7 can be fitted into the recess 10 in the state as it is. Can not. In this case, for example, as shown in FIG. 7, the fixed projection 7 is slightly oblique and its tip is applied to the inlet 19, and then the fixed projection 7 is moved along the surface 13 of the base material. When fitted into the recess 10, the adjustment piece 12 undergoes moderate compressive deformation and partial destruction, and
Can be fitted into the recess 10 without difficulty (FIG. 8).

FIG. 9 shows a case where the decorative panel 1 is juxtaposed on the surface 13 of the base material using the waist edge 21 to form the decorative wall surface 16. The juxtaposition of the decorative panel is as described above. Same as in the case.

FIG. 10 shows a case in which an adjustment piece 12 made of a foamable rubber material having elastic restoring property is attached to the back surface of the fixing projection 7 so as to sandwich the screw hole 11. In this case, even if the adjusting piece is made of a relatively hard material such as rubber, there is no resistance when the screw penetrates the adjusting piece, so that the fixing protrusion can be easily fixed to the screw.

[0018]

[Effects of the Invention] The present invention is configured as described above, and has the following excellent effects. Since the adjustment piece having elastic compressibility is stuck on the back surface of the fixing protrusion, when fixing the decorative panel, the compression amount of the adjustment piece is adjusted to fix the base material while absorbing the unevenness of the surface of the base material. By fixing the protruding pieces to the surface of the base material with screws, a smooth decorative surface (wall surface or the like) can be formed regardless of the unevenness of the surface of the base material.

When fixing another decorative panel on the surface of the base material adjacent to the fixed decorative panel,
When the fixing protrusion of the adjacent decorative panel is inserted into the concave portion on the back side of the base decorative panel, an appropriate compressive deformation occurs in the adjustment piece on the back side of the fixing protrusion of the adjacent decorative panel. The unevenness of the surface of the base material is absorbed by the compressive deformation of the adjusting piece, so that the required level of the side edge of the basic decorative panel and the side edge of the decorative panel adjacent thereto can be obtained at once. That is, the unevenness adjustment of both adjacent decorative panels,
It is easily and satisfactorily obtained by being restricted by the basic decorative panel.

Also, in the present invention, the decorative panels are connected to each other in a state where the fixing projections having the adjusting pieces of one decorative panel are inserted into the recesses of the other decorative panel (the decorative panel). Since the panels are related to each other), even if an external force acts on the formed decorative panel surface, the level of the boundary between adjacent decorative panels is unlikely to shift.

When a fixing protrusion of the decorative panel is newly fitted to the inlet of the decorative panel already fixed to the concave portion, the fixing protrusion is fitted as it is because the gap dimension of the inlet is small. Even in the case where it is impossible, since the adjusting piece has elastic compressibility, it is possible to fit the fixed protruding piece into the concave portion by appropriate compressive deformation or partial destruction.

Even if a construction error occurs when the decorative panels are juxtaposed, since the fixed protruding pieces have a clearance in the longitudinal direction in the concave portion, each decorative panel can be smoothly arranged in a required arrangement. Can be installed side by side.

In particular, when a nonflammable thin plate such as a natural stone is used as a decorative plate, a nonflammable plate such as a silica plate is used as a reinforcing plate, and a nonflammable material such as a calcium carbonate foam is used as an adjusting piece. Is preferable because the fire resistance of the whole decorative board can be improved.
