Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a method for manufacturing an outer wall plate in which tiles are arranged on the surface of a cement substrate.

[0002]

2. Description of the Related Art Conventionally, there is an outer wall plate having tiles arranged on its design surface (Japanese Patent Laid-Open No. 11-350704, etc.). The outer wall plate constitutes a design surface by attaching a large number of the tiles to the surface of a cement substrate with an adhesive.

[0003]

However, the above-mentioned conventional outer wall plate is formed by simply adhering the tile to the flat surface of the cement substrate with an adhesive. Therefore, it is difficult to position the tiles. Therefore, the tiles may be vertically or horizontally displaced or slanted and may be attached, and the appearance and design may be deteriorated.

Further, the load of the tile is applied to the adhesive, and the tile has a insufficient fixing force to the cement substrate, which may cause the tile to fall off. Further, in the outer wall plate, the interface between the tile and the cement substrate is easily noticeable. Therefore, there is a problem that it is easy to understand that the above tiles are attached and the design is poor in appearance.

The present invention has been made in view of the above conventional problems, and an object of the present invention is to provide a method of manufacturing an outer wall board having excellent workability and fixing force of tiles on a cement substrate and excellent appearance design. To do.

[0006]

The invention according to claim 1 is characterized in that
Forming a cement substrate with multiple recesses, and then
Apply adhesive to the bottom of the recess and then the tile
Insert the back side into the recess and attach the tile
Glue the back side to the adhesive and place the tiles above
A method for manufacturing an outer wall plate disposed in each recess, comprising :
When applying the adhesive to the bottom surface of the recess,
Adhesive transfer plate having a plurality of transfer protrusions corresponding to recesses
The adhesive is applied to the transfer surface of the transfer protrusion in
Then, the transfer surface is brought into contact with the bottom surface of the concave portion and
The method for producing an outer wall plate is characterized by transferring the adhesive .

What is most noticeable in the outer wall plate obtained by the present invention is that a plurality of recesses are formed on the front side surface of the cement substrate, and the back side of the tile is fitted into the recesses. That is. The back side portion means a portion having a predetermined thickness from the back side surface which is the side opposite to the design surface of the tile. Further, the recessed portion of the cement substrate can be formed by embossing.

Next, the function and effect of the present invention will be described.
The outer wall board obtained by the present invention has a plurality of recesses in the cement substrate, and the tiles are arranged in the recesses. Therefore, in manufacturing the outer wall plate, positioning when the tile is applied to the cement substrate can be easily and reliably performed. That is, the tiles are not attached vertically or horizontally or obliquely, and an outer wall plate having an excellent appearance design can be obtained.

Further, since the back side portion of the tile is fitted into the concave portion and an adhesive agent is interposed between the concave portion and the concave portion, the fixing force of the tile to the cement substrate is high. Therefore, there is no risk that the tile will fall off the cement substrate. Further, in the outer wall plate, since the edge of the back side surface of the tile is arranged in the recessed portion, the interface between the tile and the cement substrate is inconspicuous. Therefore, a feeling of unity between the tile and the cement substrate is expressed, and the external appearance of the outer wall plate is improved.

As described above, according to the present invention, it is possible to manufacture the outer wall board which is excellent in the workability and the fixing force of the tile on the cement substrate and has the excellent appearance design.

Further, the tiles may preferably have a joint groove on the design surface (see FIGS. 7 and 8). As a result, the design surface of the tile is divided into a plurality of pieces by the joint groove portion. The divided design surface has the same appearance as the design surface in which a plurality of tiles are arranged. Therefore, by using one large tile, it is possible to omit the work of arranging a large number of tiles on the cement substrate, which facilitates manufacturing.

Next, a method of manufacturing the outer wall plate 1 of this example will be described. As shown in FIG. 2A, first, the cement substrate 2 having a plurality of concave portions 22 on the front side surface 21 is formed.
Next, as shown in FIGS. 2A and 2B, the adhesive 12 is applied to the bottom surface 221 of the recess 22.

Then, as shown in FIGS. 1 (B) and 2 (C), the back side portion 32 of the tile 3 is fitted into the recessed portion 22, and the back side surface 33 of the tile 3 is attached to the adhesive 1.
2 to attach the tiles 3 to the recesses 22.
To be installed. At this time, as shown in FIG. 2B, the adhesive 12 applied to the bottom surface 221 of the recess 22 is
As shown in FIG. 2C, the tile 3 is spread by the back side surface 33 and flows to the side wall 222 of the recess 22. As a result, the outer wall plate 1 having the tile 3 arranged on the design surface 11 as shown in FIG. 1 is obtained.

The adhesive 12 is applied to the bottom surface 221 of the recess 22.
3 is used, an adhesive transfer plate 4 having a plurality of transfer protrusions 41 corresponding to the recesses 22 is used as shown in FIG. Note that FIG. 3B is a view of the adhesive transfer plate 4 viewed from the transfer surface 42 side.
