Abstract

PROBLEM TO BE SOLVED: To attempt wt. reduction, to obtain a large deflection strength, to fit strongly the surface material of a tile, etc., and improve resistance to water- permeability by providing a surface material, a fiber-reinforced plastic sheet provided on the back surface of the surface material and a frame provided on the back surface of the sheet. SOLUTION: This decorative panel is completed by spreading a surface material 2 consisting of a plurality of tiles 1... on a fixing plate 6 so as to make the back surface 2a of the surface material 2 face upward, laminating a sheet 3 consisting of a fiber-reinforced plastic thereon, placing a frame body 4 or a warpage preventing reinforcing plate 5 on the back surface 3a of the sheet 3 before a resin impregnated in this sheet 3 is cured and removing this decorative panel from the fixing plate 6 after the thermosetting resin is cured and the sheet 3, tiles 1..., the frame body 4 and the warpage preventing reinforcing plate 5 are integrated into a body.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a veneer used for interior and exterior materials of buildings.

[0002]

2. Description of the Related Art As a veneer of this type, for example, there is one in which tiles are adhered on an asbestos slate material.

[0003]

However, in the conventional veneer described above, the weight as a whole is large, the flexural strength is small, and the adverse effect of dust on the human body becomes a social problem. ing. Furthermore, the tile has low adhesive strength and low water permeation resistance, and there is a risk that water may enter the inside and damage the base of this veneer. Also,
Conventionally, a slate material containing no asbestos has been developed, but it is difficult to control the water absorption rate, and deformation may occur depending on the defect.

Therefore, according to the present invention, the weight can be reduced, the productivity is high, the flexural strength is large, the structure wall can stand on its own, and the surface materials such as tiles can be firmly attached. The purpose of the present invention is to provide a veneer with high water permeation resistance.

[0005]

In order to achieve the above object, a decorative board according to the present invention comprises a surface material, a sheet body of fiber reinforced plastic attached to the back surface of the surface material, and the sheet body. And a frame body attached to the back surface of the. Further, it is preferable to provide a warp preventing reinforcing plate on the back surface side of the sheet body.

[0006]

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

FIG. 1 shows a manufacturing state of a decorative board according to the present invention, which is a surface material 2 composed of a plurality of tiles 1.
And the frame body 4 attached to the back surface 3a of the sheet body 3, and the frame body 4 attached to the back surface 3a of the sheet body 3, and the reinforcing plate 5 is the back surface of the sheet body 3. It is attached to 3a.

Next, a method of manufacturing this veneer will be described.
First, as shown in FIG. 2A, a plurality of tiles 1 ... Are laid on a fixed platen 6 with their back surfaces 1a facing upward. In this case, tiles 1 ... Are arranged in 8 rows and 4 columns in the example shown in the figure, but of course the invention is not limited to this.

Next, a sheet body 3 made of fiber reinforced plastic is laminated on the tiles 1 ... The sheet body 3 is a thermosetting resin to which short cut glass fibers are added, and the glass fibers are randomly bound on a sheet (so-called glass mat), or glass fibers are woven ( So-called glass cloth) and the like.

After that, before the resin with which the sheet body 3 is impregnated is cured, as shown in FIG.
Is placed on this sheet body 3. In this case, the frame body 4 is
The rectangular frame 7 and the vertical sides 7a of the rectangular frame 7 and the connecting sides 8, 8 connecting the vertical sides 7 are connected to each other. However, the present invention is not limited to this, and a warp preventing reinforcing plate 5 is attached as shown in the figure. In this case, similarly, before the resin is hardened, the reinforcing plate 5 is placed on the sheet body 3 as shown in FIG. As the warp prevention reinforcing plate 5, for example, a veneer plate having a thickness of about 2.5 to 3 mm is used. In addition, the illuminator,
When attaching a faucet device, grip bar, etc., a holding plate piece with a relatively large thickness (about 10 mm) at the attachment site
Place 10

After the thermosetting resin is cured (that is, after the sheet body 3, the tiles 1 ..., the frame body 4, the reinforcing plate 5 and the holding plate piece 10 are integrated), the fixing plate 6 applies this makeup. Complete by removing the board (demolding). In addition, in FIG.
Is a masking material, and 13 is an outer frame fixed to the fixed platen 6.

By the way, as a decorative board, a thermosetting resin (preferably colored) may be applied before laminating the sheet body 3 on the surface material 2 in order to further improve the waterproof effect. That is, as shown in FIG. 5, the fixed platen 6 provided with the recess 12 into which the surface material 2 made of the tiles 1 is fitted is provided on the upper surface 6a, and after the surface material 2 is dropped into this recess 12. The colored thermosetting resin may be applied to the surface material 2 and its periphery, and then the sheet body 3 may be laminated as described above, and the above steps may be performed. The reason why the colored thermosetting resin is used is to form a beautiful appearance portion on the surface other than the tiles 1.

Further, as shown in FIG. 3, the fixed plate 6 may have an end edge 14 in an arc shape. In this case, the tiles 1 ... Corresponding to the end edge 14 have this arc shape. Will be placed along. Further, as the fixed platen 6, as shown in FIG. 4, a corner type having a horizontal wall 15 and a vertical wall 16 may be used. In this case, the angle formed by the horizontal wall 15 and the vertical wall 16 does not necessarily have to be a right angle.

As the surface material 2, in addition to the tile 1, natural marble such as natural marble and granite, calcium silicate board, inorganic board such as flexible board, organic board such as melamine decorative board, natural wood, and attached board. Wood boards, artificial marble, etc. can be used. The warp prevention reinforcing plate 5 may be a metal plate or the like other than the veneer plate. That is, since the reinforcing plate 5 is for preventing the "warp" of the decorative board, it does not necessarily correspond to the entire surface material 2, and may be omitted altogether. Even if omitted completely, there is no problem in strength.

[0015]

Since the present invention is configured as described above, the following effects can be obtained.

The overall structure is simple, the weight can be reduced, and the productivity is improved. It has high flexural strength, can stand as a structural wall, and has no adverse effect on human body due to dust. (Because the entire back surface of the surface material 2 is covered with fiber reinforced plastic), the adhesive strength of the surface material 2 is great and it is stable as a makeup board, and the water permeation resistance is high, and this makeup board is attached without water entering inside. It does not violate the base. The smoothness of the surface of the surface material 2 is easily obtained, and when natural stone is used for the surface material 2, variation in the thickness of the natural stone is not generated. As for the manufacturing equipment, simple equipment (without requiring expensive equipment) may be used.
