Description

[Detailed Description of the Invention] The present invention relates to a tile of a tile unit used in the so-called tile pouring method, in which a tiled wall surface is obtained by a tile pouring precast concrete slab or a tile pre-installation method.

In general, the tile units used in the tile pouring method are either the joint base or the unit base.
There are two main types when the tile sheet is used as a unit base. The tile unit when the joint base is used as a unit base is as shown in Figures 1 and 2, in which a recess 2 for tile fitting is bored in the joint square 1 made of rubber material, styrofoam, etc. with a predetermined joint gap. A tile unit A is formed by fitting a tile 3 into the recess 2 and connecting a plurality of tiles 3. On the other hand, when a tile sheet is used as a unit base, the tile unit is as shown in Figures 3 and 4, and is a lattice-like joint frame with 4 squares for inserting tiles at predetermined joint gaps. After preparing the joint frame 5 and inserting the tiles 3 into the squares 4 of the joint frame 5, the joint frame 5 and the tiles 3 are pasted together with a tile sheet 7 made of adhesive 6 applied to the surface, and a plurality of The tiles 3 are connected to form a tile unit B.

However, since the tiles 3 are fired at a high temperature of about 1000 to 1400°C, the size of each tile varies due to differences in thermal expansion and contraction during firing. Therefore, the size of the recess 2 for fitting the tile and the square 4 for inserting the tile had to be made slightly larger than the size of the tile 3 described above. According to such a fitting relationship, a gap is formed between the side surface 2a of the recess 2 and the side surface 4a of the square 4, and the side surface 3a of the tile 3, and from this gap, cement paste or concrete is poured into the concrete during concrete pouring. The contained moisture sometimes leaked onto the tile surface 3b and stuck to the tile surface 3b. The cement paste adhered to the tile surface 3b had to be removed after demolding, which added to the work process and created a risk of damaging the tile surface 3b during removal.

The present invention has been developed to improve and eliminate the above-mentioned drawbacks of the conventional technology.The present invention consists of a tile main body, a water-soluble paper that has the ability to swell and become several times thicker when it contains water, and a tile that dissolves in water. Organic solvent-based adhesives such as acrylic and rubber-based adhesives that do not contain
The swellable water-soluble paper is adhered to the side surface of the tile body using an adhesive material such as PVA adhesive or ordinary adhesive.

The configuration of the present invention will be explained below based on the embodiments shown in the drawings.

FIG. 5 shows a tile 8 of the present invention. This tile 8 has a water-soluble paper 9 attached to the side surface 8b of the tile body, which has a swelling property and becomes several times thicker when it contains moisture. The adhesion area on this tile side surface 8b is from the tile surface 8b to the joint frame 5.
(See Figure 3) height or convex portion 1a of joint square 1
(See Figure 2). This will become clear with reference to FIGS. 6 and 7. As the water-soluble paper 9, it is sufficient to use one that is already commercially available. According to the results of experiments with this commercially available product, when water-soluble paper with a thickness of 0.5 to 0.25 mm was cut into lengths of 50 mm lengthwise and widthwise, and 9 to 10 c.c. A swelling rate of 20 times higher was obtained. Also, when pasting the water-soluble paper 9, its material 10
(See Figures 6 and 7) using an organic solvent-based adhesive such as acrylic or rubber-based adhesive that dissolves in water or does not contain water, PVA adhesive, or ordinary adhesive such as double-sided tape. Just do it.
The point is that the adhesive material 10 does not swell the water-soluble paper 9 and that the adhesive material 10 itself does not roughen the joints.

FIG. 6 shows the tile 8 of the present invention having the above-mentioned structure.
Fig. 7 is a longitudinal cross-sectional view of the tile unit A shown in Fig. 4 when the tile 8 of the present invention is applied to the tile unit B shown in Fig. 4. It is a diagram.

These tile units A and B are used by being attached to a base plate or a formwork (not shown).
Then, before pouring concrete, water is sprinkled to swell the water-soluble paper 9. This water-soluble paper 9 has an excellent swelling rate, and when it swells with the water spraying, a gap is formed between the tile side surface 8a and the concave side surface 2a of the joint frame 1, and a gap is formed between the tile side surface 8a and the joint frame 5.
The gap formed between the square side surface 4a and the square side surface 4a is filled. Therefore, when concrete is poured in such a state, the cement paste from the above-mentioned portions and the moisture contained in the concrete will not leak onto the tile surface 8b, and the conventional drawbacks can be solved. In order to swell the water-soluble paper 9, since the water-soluble paper 9 exhibits an excellent swelling rate as described above, it is also possible to swell the water-soluble paper 9 by water contained in concrete during concrete pouring. Some water-soluble paper 9 swells only with an alkaline aqueous solution, but when such a water-soluble paper is used, an alkaline aqueous solution having a concentration of about 2% may be sprayed before pouring the concrete.

As explained above, the present invention uses organic solvent-based adhesive, PVA adhesive, or regular adhesive to attach water-soluble paper, which has the property of swelling and becomes several times thicker when it absorbs moisture, to the side surface of the tile body. Therefore, when constructing a tile unit using this tile, the above-mentioned water-soluble paper is swollen by sprinkling water before concrete pouring, and the recessed side of the tile side and the joint frame, or the square of the tile side and the joint frame. It can fill the gap formed between the side surface and the
The moisture contained in the cement paste or concrete will not leak out onto the tile surface from this part. Therefore, there is no need to remove the cement paste stuck to the tile surface after demolding, as is the case in the past, and the work process can be simplified.
