Description

[Detailed explanation of the idea] This idea concerns improvements to tiles.

Tiles are used as a covering material for the walls and floors of buildings.

When adhering these tiles to the base surface, mortar containing an admixture is applied to the base surface in advance, and the tiles are pressed against the mortar area using the pressure bonding method, or the tiles are arranged and fixed on the mold surface in advance. There is a pre-concrete method that involves pouring concrete. In gluing such tiles,
In order to ensure sufficient adhesive strength, in the case of tiles with a large surface area, a backing consisting of uneven parts such as ribs is attached to the back side of the tiles.

However, even when a backing is attached, for example, when the tile is pressed against mortar using the above-mentioned pressure bonding method, the mortar does not fully penetrate into the corners of the backing, creating voids and insufficient adhesive strength. The problem was that there were times when it could not be done.

This invention was made in view of the above-mentioned conventional problems, and aims to provide a tile that has extremely good adhesion strength to the underlying surface.

This invention is based on a tile having an uneven part on the back surface, in which one end of a coiled anchor is elastically fitted into the uneven part, and the other end of the coiled anchor is made to protrude from the back surface of the tile. It is a feature.

Next, an embodiment of this invention will be described based on the drawings.

1 to 4 are diagrams showing an embodiment of this invention, in which a rib-like uneven portion 1 is provided on the back surface of the tile 1.
It has a. In this uneven portion 1a,
A coiled anchor 2 as shown in FIG. 3 is fixed using the elasticity of the coiled anchor 2.

When fixing this coiled anchor 2, one end of the coiled anchor 2 is pushed in the diametrical direction to slightly deform it into an elliptical shape, and then released after fitting into the uneven portion 1a, or the coiled anchor 2 is This can be easily done by turning the coiled anchor 2 in the winding direction to slightly reduce the diameter of one end, fitting it into the uneven portion 1a, and then releasing it, so that the other end of the coiled anchor 2 protrudes from the back surface of the tile 1. state.

Therefore, if such tile 1 is
When adhering to the base surface 3 shown in the figure, first apply mortar 4 containing an admixture to the lower surface 3, and then press the tile 1 onto the mortar 4, so that the coiled anchor 2 is embedded in the mortar 4. Therefore, even if the mortar 4 is not in close contact with the uneven portion 1a, the adhesive strength of the tile 1 can be made sufficient.

Although the coiled anchor 2 in FIG. 3 has the shape of a conical coil spring, it may naturally have the shape of a general coiled spring with a constant diameter.

FIG. 5 shows another example of the shape of the coiled anchor 2, in which it is in the shape of a chain. At this time, if the diameters d ₁ and d ₂ of both ends are changed, the same coiled anchor 2 can be used for two types of tiles with different groove widths of the uneven portion 1a by selecting the ends thereof. be able to.

FIG. 6 and FIG. 7 are views showing another embodiment of this invention, in which the uneven portion 1a consists of a circular groove.
The fixing can be made even better,
Therefore, the adhesive strength of the tile 1 to the base surface 3 can be increased.

In addition, the present invention can also be applied to a case where the uneven portion 1a is formed of a rectangular groove or a polygonal groove.

FIG. 8 shows another example of how to attach the tiles 1 shown in FIG. Even when the tile 1 is peeled off from the base surface 3 at the mortar 4 part, the danger of the tile 1 falling is eliminated.

As explained above, according to this idea,
In a tile having an uneven surface, one end of the coiled anchor is elastically fitted into the unevenness, and the other end of the coiled anchor is made to protrude from the back surface of the tile. As a result, it is possible to obtain a strong interlocking state, and the adhesive strength between mortar or concrete and tiles can be significantly improved, which has great practical value as it can eliminate the risk of tiles falling. It has the following effect. In addition, since the coiled anchor is used, it is relatively easy to expand and contract, and can be adapted to changes in the thickness of mortar and concrete. It is possible to easily deal with cases such as changing the number of anchors as appropriate depending on various combinations and the condition of the underlying surface.
