Description

[Detailed Description of the Invention] The present invention relates to a decorative panel that is widely used as interior and exterior materials for buildings.

As shown in FIG. 1, a conventional decorative panel 1 of this type is constructed by attaching an annular frame 3 made of metal such as aluminum along the outer edge of the back surface of a plate base 2 using a rubber adhesive. A large number of tiles 4 were regularly arranged and pasted on the surface of the base 2 using an epoxy adhesive.

This decorative panel 1 has a large number of tiles 4 attached to it, and by attaching the decorative panel 1 side by side to the exterior wall material (not shown) of a building, a large number of tiles 4 can be attached to the entire surface of the side wall material. It has excellent workability because it gives the same appearance as pasting one sheet at a time. However, the conventional decorative panel 1 described above not only has the disadvantage that it requires a great deal of time and effort to regularly line up and paste a large number of tiles 4 on the surface of the base 2, but also Since the base 2 was made of asbestos slate material, the strength of the base 2 was weak, which made it difficult to manufacture a large-sized one. In addition, since asbestos slate material itself is heavy, combined with the weight of tiles 4, it is difficult to reduce the weight of decorative panel 1, and furthermore, due to the characteristics of asbestos slate, base 2 has the property of easily absorbing water. In addition to requiring waterproofing treatment, the tile 4 may peel off if the treatment is insufficient. Another drawback was that dew condensation easily formed on the surface of the tiles 4 due to the lack of heat insulation.

On the other hand, in place of the tiles described above, decorative panels made of synthetic resin with joints on the surface have been used, but these also have the same drawbacks as those described above.

This invention was made to improve the drawbacks of the conventional method. Synthetic resin is injected into the surrounding part of the annular frame with a net stretched on the back side and foamed, and a large number of tiles are placed on the surface of the foamed layer. Alternatively, by fixing a decorative board to the foam, it is possible to provide a decorative panel that has excellent workability and heat insulation properties, does not allow tiles or decorative boards to peel off, is lightweight, and is easy to install. purpose.

The present invention will be described below with reference to illustrated examples.

FIG. 2 is a perspective view showing a part of the decorative panel 1, and what is illustrated in the figure is a rectangular annular frame 1.
A net 12 is stretched on the back surface of the frame 11, and a synthetic resin foam 13 is provided integrally with the frame 11 in the surrounding area of the frame 11, and a large number of tiles 14 are arranged regularly on the surface of the foam 13. They are lined up and fixed.

As the frame 11, a wooden one can be used in addition to the metal one explained in FIG. 1, and in that case, it is easier to achieve weight reduction of the decorative panel 1 than when using a metal frame. Note that the frame 11 may have an annular shape or other shapes, but in general, a rectangular annular shape is preferred except when used for special purposes, such as side walls with rounded corners. used. In addition to woven or nonwoven fabrics made of natural or synthetic fibers, wire mesh, plastic net, glass net, or the like may be used for the net 12. This net 12 holds the foam 13 and enhances its reinforcing effect. Further, as the foam 13, urethane, phenol, epoxy and other water-resistant foams are preferably used. This foam 13
is preferably obtained by injecting a synthetic resin into the surrounding portion of the frame 11 and then foaming it. That is, by doing this, the foam body 13 is firmly fixed and integrated with the frame body 11 and the net 12 without using an adhesive through the foaming process, and
If the frame 11 is placed on a large number of regularly arranged tiles prior to the foaming process, a large number of tiles 14 will be simultaneously formed into the foam 1 by the foaming process.
This is because it is firmly fixed to the surface of 3.

According to the above, since the tile 14 is firmly fixed to the foam 13 during the foaming process, there is no fear that the tile 14 will peel off, and the foam 13 itself is lightweight and has excellent heat insulation properties. The decorative panel 1 becomes easier to handle and workability is improved. Furthermore, due to its excellent heat insulating properties, dew condensation is less likely to occur on the surface of the tile 14. Furthermore, since the foam 13 is backed up by the net 12, the foam 13 is less likely to be damaged, and its strength is greatly improved compared to the conventional one which also uses an asbestos slate base. Therefore, it becomes possible to easily increase the size of the decorative panel 1. In addition, the characteristics of the foam 13 make it excellent in water resistance and water resistance, making it particularly suitable for use as an interior material for bathrooms and the like.

In addition, in FIG. 2, tiles 1 are placed on the surface of the foam 13.
4 has been described, but the same effect can be obtained if a decorative board with a relatively thin thickness, for example, 5.0 mm or less, is used instead of tiles. In this case, it is desirable to use a synthetic resin decorative board to ensure water resistance and water resistance, but even if it is made of wood, synthetic resin can be used if the surface is treated with a resin. It is possible to ensure water resistance and waterproofness equivalent to that of

FIG. 3 shows a modification. That is, the decorative panel 1 shown in the figure has the net 12 stretched not only on the back side of the frame 11 but also on the front side.
According to this, the foam 13 is made of two nets 12,
12 in the shape of a sandwich, it has the advantage that its strength is improved over that of the one shown in Fig. 2, and it also has the advantage of improving its adhesion to the surface tiles or decorative board.
When using adhesive, it has good adhesive retention.
Adhere firmly. Since other matters are the same as those explained in FIG. 2, the same reference numerals are given and details are omitted.

As detailed above, the decorative panel of the present invention is easier to manufacture than conventional products, has excellent workability, strength, heat insulation, water resistance, and waterproofness, is lightweight, and is suitable for use with tiles and decorative boards. No worries about it peeling off. In addition, a net is stretched on the back of the frame to hold the foam, so the foam is less likely to be damaged.
It is convenient to handle during transportation, etc., and has the advantage of being easy to attach to exterior wall materials.
