However, in the decorative panel in which the surface of the lightweight cellular concrete plate is grooved to form the joint, the same coating is applied to the surface of the lightweight cellular concrete plate. Since there is no color tone, there is no change in color, there is a lack of solidity, and there is a problem of poor design. In addition, there are some decorations with different spray paint colors above and below the floor of the building, but even in this case, one decorative panel itself has no color tone and changes little, There was a problem that it lacked profoundness and was inferior in design.

A decorative panel in which the surface of the latter lightweight cellular concrete plate described above is masked according to a joint pattern and then another type of coating is applied, and a joint pattern such as a tile pattern is displayed by the coating, is known. However, there is a problem in that the entire design is flat and lacks in solidity because it has only the thickness of the coating, resulting in a design with no depth.

The decorative panel with joints according to the present invention is a completely new technology developed in view of the above-mentioned conventional problems, and in particular, the surface of a lightweight cellular concrete plate is provided with a groove serving as a joint to form irregularities. In addition, by laminating two kinds of coating layers having different color tones on the surface of this lightweight cellular concrete plate in order, smoothness and waterproofness are given to the surface of the lightweight cellular concrete, and the joint contrast is displayed to increase the depth. It is intended to provide a technique of a decorative panel which is rich in profoundness.

A decorative panel with joints according to the present invention is a technique that has fundamentally improved the above-mentioned conventional problems, and its gist is a lightweight structure in which a groove serving as a joint is formed. A first coating layer in which a colored first coating layer is applied to the entire surface of the aerated concrete plate, and the groove for forming the joint is removed.
A second coating layer having a color tone different from that of the first coating layer on the surface of the coating layer;
A decorative panel with joints, characterized in that a covering layer is provided.

[0009]

In the decorative panel with joints according to the present invention, as described above, since the groove groove serving as the joint portion is provided on the surface of the lightweight cellular concrete board, a concavo-convex pattern is formed on the surface to provide a joint design with depth. Can be displayed. Further, since the colored first coating layer is laminated on the entire surface of the lightweight cellular concrete plate, the pinholes and the rough surface provided on the lightweight cellular concrete plate are smoothed by this, and the joint portion is formed. It is possible to color and waterproof the entire surface including the groove to be formed, and to significantly improve the adhesiveness of the second coating layer laminated on the first coating layer.

In the decorative panel of the present invention, the second coating having a color tone different from that of the first coating layer is formed on the surface of the lightweight cellular concrete plate excluding the grooves serving as joints of the first coating layer. Since the layer is provided, it is possible to change the color tone of the groove and the second coating layer, which are joints, so that the joints can be made conspicuous to give a contrast, and a prominent design It is possible to construct a high-quality makeup panel.
