BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tile unit used in a tile-casting method for obtaining a tile-finished wall surface by a tile-casting precast concrete plate or a tile site pre-adhesion method.

[0002]

2. Description of the Related Art In general, tile units used in a tile driving method are roughly classified into two types: tiles are inserted into joints having squares for tile insertion, and these are then made of polypropylene, polyvinyl chloride, polyester, or the like. Adhesive is applied to a tile sheet made of plastic film or paper with adhesive, and a tile sheet that connects a plurality of tiles is used as a unit base, and a tile made of rubber, styrene foam, etc. A joint base for connecting a plurality of tiles by fitting is used as a unit base.

[0003] In these tile units, the size of the tiles for inserting the tiles has been manufactured to be slightly larger than the size of the tiles because of variations in tile dimensions.

[0004] For this reason, there is a risk that the tiles may be displaced or fall off before the concrete is cast. In addition, when the concrete is cast, the cement paste leaks out from the gap between the tile and the inside of the tile insertion mesh, and the tile surface is displaced. Flows out to
There was a defect of sticking to the tile surface, and the appearance of the finished tile surface was significantly impaired. For this reason, Japanese Patent Application Laid-Open No. 57-161258 discloses that in order to solve the problem of leakage of cement paste, a water-soluble paper having swelling property is attached to the above-mentioned space to prevent the leakage of cement paste.

[0005]

[Problems to be Solved by the Invention] However, when water is applied to the water-soluble paper having the swelling property, the pulp in the water-soluble paper is disintegrated. The aesthetic appearance of the tile surface was significantly impaired.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks and has been improved in view of the above-mentioned drawbacks. The present invention provides an inflatable member in which a water-absorbing paper and an inflating material are laminated in a sandwich shape between a tile and an joint. By providing a tile unit that is stuck and connected to connect tiles and joints with a tile sheet, this prevents leakage of cement paste and also makes the finish of the tile surface beautiful. is there.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below 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, a joint body 1 is composed of a vertical joint member 2 and a horizontal joint member 3, and both side surfaces 4 and 5 of these joint members 2 and 3 are formed. Next, as shown in FIG.
2 is adhered to an inflatable member 10 in a sandwich shape. As a method of sticking, a double-sided tape may be used, and an adhesive may be applied to the joint body 1 side or the expandable member 10 side. As the expanding material, one part from its own weight
A highly water-absorbent resin that absorbs 000 times as much water is used. Also,
The intumescent member 10 is laminated by a normal laminating method in which the intumescent material 12 is evenly spread and sandwiched between the water-absorbing papers 11 and 11 and pressed by a roller.

Next, a jig 1 for tile alignment shown in FIG.
3 is used to align the tiles 15. The tiles 15 are designed to have a predetermined joint spacing only by being fitted into the tile fitting recess 14 of the jig 13 with the tile surface 16 facing upward. When the arrangement of the tiles 14 is completed,
The joint members 2 and 3 for which the inflatable member 10 is prepared to be attached are arranged on the projecting portion 17 of the jig 13. Then, the joint body 1 on which the tile 14 and the expansible member are adhered is adhered to a tile sheet 18 made of a plastic film such as polypropylene, polyvinyl chloride, polyester, or a paper member via an adhesive, and a tile unit is formed. Is configured.

As shown in FIG. 4, when the tile unit 20 is fixed to a formwork or plywood 21 and water is sprayed with a sprayer, the water absorbing paper 1
1 absorbs water, and then the expansion material 12 absorbs and swells, thereby eliminating the gap between the tile 15 and the joint body 1. Thereafter, when concrete is poured, leakage of the cement paste to the tile surface can be prevented. Concrete Cured Earth 1
When is dried, the expanding material shrinks, and the mold can be easily removed.

[0011]

[Effect of the Invention] In summary, in the present invention, since a swellable inflatable member in which a water-absorbing paper and an inflating material are sandwiched between a tile and a joint body is stuck and arranged, the water is poured before the cement is poured. Can prevent the cement paste from leaking to the tile surface by simply spraying the water. The rear tiles and joints are beautifully finished. In particular, since the expandable member of the present invention laminates the absorbent paper and the expandable material in a sandwich shape, the expansion of the expandable member is limited only in the sandwich direction. The member expands between the tile and the joint body to prevent leakage, and also eliminates any disturbance of the joint after finishing.
