Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to ceramic tiles that are attached to walls of buildings, etc.

An absolute requirement for this type of tile is that it cannot be removed after it has been attached to a building or the like.

To this end, conventionally, various irregularities, such as grooves, have been formed on the back surface of the tile.

However, simply forming irregularities on the back surface of the tile cannot completely prevent the tiles from peeling off.

Especially in buildings that have been constructed for a long time, the tiles often fall off, which poses a safety problem.

Recently, peeling of tiles has become a problem in earthquake countermeasures, and the reality is that we are struggling to find a way to prevent this.

Furthermore, conventional tiles cannot prevent rainwater and the like from penetrating between the tiles and the mortar layer.

As a result, efflorescence occurred, and rainwater, etc., froze, causing frost damage.

The purpose of this invention is to provide a ceramic tile that can completely prevent peeling off and prevent rainwater from seeping in.

This will be explained below with reference to the illustrated embodiment.

The tile body 1 of this embodiment has grooves 2 formed around its side surface.

The tile body 1 thus constructed is temporarily fixed by being slightly embedded in the mortar layer 4 formed on the wall surface 3.

The -1- tile main body 1 temporarily attached to the mortar layer 4 is further pressed using a vibrator or the like to completely adhere the tile to the mortar layer.

When the tile bodies 1 are embedded to some extent in the mortar layer as described above, the mortar is pushed away from the joints 5 between the tile bodies 1 and also enters into the grooves 2, as shown in FIG.

When the mortar hardens in the groove 2, it is clear that the hardened mortar acts like a stopper against the tile body 1.

Note that the grooves 2 in this invention do not necessarily correspond to the tile body l.
It does not have to be formed around the entire side surface.

However, if the grooves 2 are formed all around the side surface of the tile body 1 as in this embodiment, the length of the hooked part of the tile body 1 becomes longer, which increases the strength in the peeling direction. It turns out.

Therefore, it goes without saying that the length of the groove 2 will vary depending on the weight of the tile, the conditions of the building itself, etc.

The cross-sectional shape of this groove may also be changed depending on the conditions of use at that time.In short, when the tile body is embedded in a mortar layer, the width is sufficient for the mortar to penetrate into this groove. It is sufficient to maintain the depth.

As mentioned above, the most important function of the groove 2 is to prevent the tile from peeling off, but it also functions as a scale for measuring the embedded depth of the tile body 1.

In other words, if the embedding depth of the tile body 1 is set to a position where the grooves 2 are completely buried, the grooves become the scale itself. Therefore, if the grooves 2 are visible from the outside after the tile is laid, it can be determined that there is insufficient filling mortar or that the tile is insufficiently pressed.

Furthermore, since the grooves 2 are filled with mortar, the filled portions function to prevent rainwater from seeping in.

If rainwater seeps into the back side of the tile, not only will efflorescence occur, but the rainwater will freeze and cause frost damage.
This may cause the tile to peel off, but if the grooves 2 are formed around the tile body 1, there is no such worry.

As is clear from the above description, according to the ceramic tile of the present invention, grooves of a required length with sufficient width and depth for mortar to penetrate are formed on the side walls of the tile body. Therefore, when the tile is attached to the mortar layer, the mortar penetrates into the 1-mark grooves, further improving the strength of the tile in the peeling direction.

Moreover, since it is sufficient to simply form the grooves on the tile body, the cost of the tile is almost the same as in the past.

Furthermore, no special work is required during construction.

Furthermore, the grooves also function as scales when pushing the tile body into the mortar layer.

Furthermore, since the grooves are filled with mortar, the grooves function to prevent rainwater from entering.

Therefore, the occurrence of efflorescence can be prevented, and there is no need to worry about freezing damage.
