[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tile-casting precast concrete plate or a tile unit used in a tile-casting method for obtaining a tile-finished wall surface by a tile site pre-installation method.

[0002]

[Prior Art]

 In general, tile units used in the tile driving method are roughly classified into two types: a tile unit is inserted into a joint having openings for tile insertion, and then these are attached to a plastic film such as polypropylene, polyvinyl chloride, polyester, or paper. Adhesive is attached to the tile sheet made of materials using a tile sheet that connects multiple tiles as a unit base, and when the tile is fitted in a joint made of rubber material, styrofoam, etc. It can be divided as a case where a joint base that connects multiple tiles is used as a unit base.

In these tile units, since the tile size varies, the size for inserting the tile was made slightly larger than the size of the tile.

[0006] Therefore, there is a risk that the tile will be displaced or fall off before placing the concrete, and when the concrete is placed, the cement paste will leak out from the space between the tile and the inside of the tile fitting eye. There was a defect that it flowed out onto the tile surface and stuck to the tile surface, and the appearance of the finished tile surface was significantly impaired. For this reason, in JP-A-57-16125, in order to solve the problem of the leakage of the cement paste, the swelling water-soluble paper is stuck and arranged at the above intervals to prevent the leakage of the cement paste.

[0005]

[Problems to be Solved by the Invention] However, when the water-soluble paper having this swelling property is sprinkled with water, the pulp in the water-soluble paper falls apart, and since it is water-soluble, pulp scraps remain around the tiles, and after finishing, The aesthetics of the tile surface were significantly impaired.

[0006]

[Means for Solving the Problems]

 In view of the above-mentioned conventional drawbacks, the present invention has improved this problem by disposing an expansive member in which a water-absorbent paper and an expansive material are laminated in a sandwich shape between the tile and the joint body so that the tile and the joint are attached. By providing a tile unit that is connected to the body with a tile sheet, it is intended to prevent the cement paste from leaking out and to improve the finish of the tile surface.

【Example】

 Hereinafter, the configuration of the present invention will be described based on an embodiment shown in the drawings. 1 to 4 show an embodiment of the present invention.

In this embodiment, as shown in FIG. 1, the joint body 1 is composed of joint members 2 in rows and joint members 3 in rows, and both side surfaces 4 of these joint members 2 and 3 are As shown in FIG. 2, an expansive member 10 in which water-absorbent papers 11 and 11 and an expansive material 12 are laminated in a sandwich is attached to the sheet 5. As a method of sticking, a double-sided tape may be used, or an adhesive may be applied to the joint body 1 side or the expandable member 10 side. As the expansive material, a highly water-absorbent resin that absorbs several parts to 1,000 times its own weight of water is used.

Next, the tiles 15 are aligned by using the tile alignment jig 13 shown in FIG. The tiles 15 are configured so that a predetermined joint space is formed only by fitting the tiles 15 into the tile fitting recesses 14 of the jig 13 with the tile surface 16 facing up. After the arrangement of the tiles 14 is finished, the joint members 2 and 3 for which the expansive member 10 is prepared for attachment are arranged on the protrusions 17 of the jig 13 this time. Then, the joint body 1 having the tile 14 and the expansive member attached thereto is attached to a tile sheet 18 made of a plastic film such as polypropylene, polyvinyl chloride, polyester or a paper member or a paper member via an adhesive to form a tile. Make up a unit.

As shown in FIG. 4, when the tile unit 20 is fixed to the form or plywood 21 and water is sprayed with a sprayer, the water-absorbent paper 11 absorbs the water, after which the expansive material 12 absorbs and swells, and the tile 15 and Eliminate the space between joints 1. After that, by pouring concrete, it is possible to prevent the cement paste from leaking to the tile surface. When the concrete curing joint body 1 is dried, the expansive material contracts, and the demolding can be easily performed.

[0011]

[Effect of the device]

 In summary, according to the present invention, since the swellable expansive member in which the water-absorbent paper and the expansive material are laminated in a sandwich shape is stuck and arranged between the tile and the joint body, water is sprayed before the cement is placed. By doing so, it is possible to prevent the cement paste from leaking to the tile surface.Although the water-absorbent paper absorbs water, the pulp does not fall apart, and the paper does not fall apart when the mold is removed from the mold. The tiles and joints of the are finished beautifully. In particular, since the expansive member of the present invention has a sandwich of absorbent paper and expansive material, the expansion of the expansible member is limited only in the sandwich direction, and the expansive member expands when it is attached to the joint body. The member expands between the tiles and the joints to prevent leakage, and there is no disturbance in the joints after finishing.
