SUMMARY OF THE INVENTION
The conventional tile panel manufacturing methods of (1) and (2) are
Each has the following problems. Of (1) above
Problems with tile panel manufacturing method: Although the construction period is shorter than the wet method, the panel manufacturing and
It is costly because the process of attaching the illu is a separate process. Long-term durability as the tile and panel are glued together
Poor. Problems of the method for manufacturing a tile panel in (2) above
Point: Since the surface of panel 2 is flat, press pressure is
Material movement in panel 2 even if it is raised, that is, fluidity of panel 2
, So there is no tile 1 as shown in FIG.
Adhesion between panel 2 and panel becomes point adhesion, and in the long run, wet method
The risk of falling off of tiles and falling is greater. Bond the back surface of tile 1 and the front surface of panel 2 over the entire surface
100kg / cm for ²Higher pressure than above is required.
When a high pressure like
The difference in specific gravity between the
As it is raised and the tile foot 12 is fully loaded,
A crack is generated in the panel 2 in the portion that comes into contact with the foot portion 12.
It

Therefore, it is an object of the present invention to simultaneously form a panel and attach a tile to the panel,
Another object of the present invention is to provide a method for manufacturing a tile panel in which the tile can be firmly adhered to the panel, there is no fear of the tile coming off or falling, and there is no fear that the panel will be warped or cracked.

[0006]

According to the present invention, an extrusion molding method or a dewatering press molding method is used to form an uneven shape and a joint portion forming portion on a surface of a tile having a foot portion on the back surface which substantially corresponds to the uneven shape of the back surface. A panel having the above is prepared, and before the panel is cured, the above tiles are arranged on the uneven surface of the panel, and then the tile foot portion is embedded in the panel by pressing, and then the tile and the panel are cured. The above object is achieved by providing a method for manufacturing a tile panel, which is characterized by integrating and.

[0007]

In the method of manufacturing a tile panel of the present invention,
Since the surface of the uncured panel that fixes the tiles is formed in an uneven shape that roughly corresponds to the uneven shape on the back surface of the tile, by arranging the tiles on the panel and then pressing, the protrusions on the panel surface can be made fluid. Shown, flow deformation along the tile foot, the back surface of the tile and the surface of the panel will be bonded over the entire surface, by curing this, the panel is cured by reaction,
Tile and panel are firmly integrated.
