Description

[Detailed description of the invention] (Industrial field of application) The present invention relates to a composite decorative panel for building exteriors.

(Prior Art) Buildings that were traditionally made of wood are becoming fire-resistant, and the number of steel-framed buildings, one of them, is increasing rapidly.

Accordingly, exterior wall materials are also changing from wet construction methods in which exterior materials are attached to lath mortar to dry construction methods in which fireproof panels are fitted to frames.

Most decorative materials for fireproof panels are made of metal, such as enamel, stainless steel, or aluminum, but these have the cold image of metal and are not necessarily the best materials for decorative panels. Although tiles are traditionally used as a decorative material for ceramic products other than metal, the wet construction method of attaching the tiles to lath mortar is still used when installing the tiles. ing.

(Problem that the invention aims to solve) However, when this construction method is used, cracks tend to occur at the joints of the tiles, and in winter, moisture that enters the cracks expands due to freezing, causing cracks in the tiles. There were problems in that it caused problems and spoiled the aesthetic appearance. Nevertheless, the wet construction method is used for the construction of decorative materials using tiles.Even if the tiles are made into panels, when using tiles with a small area, many tiles are grouped together like a PC board. This is because the panel must be attached with mortar to a substrate that is very heavy, resulting in a panel that is extremely heavy and inconvenient to handle.

In addition, the small size of the tiles made them unsuitable for dry construction, and even if an attempt was made to use ceramic plates made from larger tiles, ceramic plates were vulnerable to impact, making it nearly impossible to use them for exterior panels.

Furthermore, although metal decorative materials and tiles are resistant to impact, their designs and colors are monotonous, so the market is demanding decorative panels with a luxurious image.

The present invention has been made to solve the above problems.

(Means for solving the problem) and (Operation) That is, in the present invention, a groove 2 of a constant width is provided in the horizontal direction at an arbitrary location on the side surface of the ceramic plate 1, and the entrance of the groove 2 is formed in the direction toward the back side. A cutout is made to the back side, a double-sided adhesive tape 3 is pasted around the back side, a fireproof panel B is glued to the processed ceramic plate A, which has been coated with adhesive 4 on the flat surface surrounded by the tape 3, and bolt holes 5 are made on one side. One end of the provided L-shaped fastener 6 without the bolt hole 5 is inserted into the groove 2 of the processed ceramic board A, and the other end is fixed to the fireproof panel B with a nail 7 or bolt. It is a decorative panel.

Here, the double-sided adhesive tape 3 and the adhesive 4 also function to prevent the processed ceramic board A and the fireproof panel B from coming apart, but more directly, they prevent the separation between the processed ceramic board A and the fireproof panel B. This is to prevent the intrusion of moisture (which in turn prevents the ceramic plate from cracking due to freezing of moisture), and also to prevent the ceramic plate from cracking due to impact. Also, the double-sided adhesive tape 3 is pasted around the back side of the ceramic plate 1, and the adhesive 4 is applied to the back side of the ceramic plate 1 surrounded by this tape 3. Make it possible to apply thickly,
This is to enable the above function to be performed more effectively.

The fixing device 6 is different from the above-mentioned functions of the double-sided adhesive tape 3 and the adhesive 4, and is provided for the direct purpose of preventing the processed ceramic board A and the fireproof panel B from coming apart, and it serves this purpose more reliably. In order to achieve this, it is desirable to arrange two pieces facing each other for each processed ceramic plate A, as shown in the illustrated example.

(Example) Figures 1 and 2 show the first embodiment of the present invention, in which a fireproof panel B made of lightweight concrete with a side of 600mm and a thickness of 100mm and a fireproof panel B of the same size as this fireproof panel and a thickness of 7mm are shown. It consists of a processed ceramic plate A,
A waterproof urethane adhesive is used as the adhesive 4 provided on the processed ceramic plate A, and a waterproof rubber asphalt adhesive is used as the double-sided adhesive tape 3.

As the fire-resistant panel B, fire-resistant building materials such as calcium silicate board, asbestos cement board, glass fiber reinforced foamed gypsum, etc. can be used instead of the above.

FIG. 7 shows a second embodiment of the present invention, with one side
Three A3 square processed ceramic plates 600mm and 7mm thick.
The joints are arranged in parallel with a spacing of 8 mm and fixed to one fireproof panel B, and both the adhesive 4 and the double-sided adhesive tape 3 are the same as in the first embodiment.

The reason why the adhesive 4 is particularly a urethane-based adhesive and the double-sided adhesive tape 3 is a rubber asphalt-based double-sided adhesive tape is because these are suitable for alleviating the impact applied to the panel surface.

As the fastener 6, any of those shown in FIGS. 5 and 6 can be used. The fastening tool 6 shown in FIG. 6 has an elastic serrated shape 8 on the side to be inserted into the groove 2 of the processed ceramic plate A, so that even if there is some dimensional error, the fastening tool always 6 is inserted into the groove 2 of the processed ceramic plate A without wobbling.

(Effect of the invention) As described above, in the present invention, since the large ceramic plate A is fixed on the surface of the fireproof panel B, this is fitted into the steel frame 9 as a fireproof decorative panel, and the fireproof panel B If the back side of the ceramic plate is properly fixed to the building, there is no need to use lath mortar, and the large ceramic plate can be easily used as an exterior wall material using the dry construction method.

Furthermore, since an adhesive is used to join the ceramic panel A and the fireproof panel B, even if an impact is applied to the surface of the ceramic panel A, the elasticity of the adhesive 4 will absorb the impact and the ceramic panel A will not break. Moreover, since the double-sided adhesive tape 3 is pasted around the bottom of the ceramic plate A, the adhesive 4 can be raised up to the height of the tape 3.
The elasticity effect can be further enhanced. Furthermore, if both the adhesive 4 and the double-sided adhesive tape 3 are waterproof, moisture will not penetrate inside the ceramic panel A and the fireproof panel B.
No cracks will occur.

Furthermore, since the ceramic plate A is larger than 200mm, there are fewer joints during construction, and large designs can be drawn on the ceramic plate A, making it possible to obtain a decorative panel that is completely different from conventional exterior decorative materials. I can do it.
