2. Description of the Related Art Conventionally, various materials have been used as materials for finishing wall surfaces of buildings such as buildings. Recently, various ceramics have been widely used with the improvement of their manufacturing methods. Originally, ceramics are excellent materials because of their durability and appearance, but they are expensive due to their difficulty in manufacturing and handling, and special conditions are required to obtain large products. And prevented the spread. Improvements in manufacturing methods have facilitated the supply of large products and have eliminated one of the factors that have hindered their spread.

[0003] However, ceramic products are still not easy to handle. For this reason, attempts have been made to make the product easier to handle by modifying the raw material composition during production. As a result, there is an improvement in that a product having a stable size is easily supplied, but this is not complete. For this reason, a method for improving the structure of the product itself has been attempted. For example, Japanese Utility Model Publication No. 56-1938, Utility Model Application Publication No. 60-11
No. 58, Utility Model Application Publication No. 61-15142, etc., propose improvements from the structural point of view.

[0004] These conventional ideas are all related to so-called armoring or feathering, with the aim of devising the backside of the surface of the product plate to firmly finish the finished wall surface. I have. In other words, in Japanese Utility Model Publication No. 56-1938, the length of the plate surface wall is made longer than the length of the plate back wall, so that the lower side of the plate overlaps the upper side of the next plate, and It is easy to construct. Further, in Japanese Utility Model Application Publication Nos. Sho 60-1158 and Sho 61-15142, when the tiles are viewed from the side, the lower side is configured to be more apart from the base than the upper side, and the upper side is nailed to the base. Just trying to finish the whole with a strong armor upholstery.

[0005] Further, the present applicant has previously filed Japanese Utility Model Application No. 3-895.
40, 89541, and 89542 provided structurally improved ceramic tiles. In other words, the difficulty of handling, which is an inevitable drawback due to the properties of ceramic tiles, particularly, the structural improvement of cracks and chipping of corners that are likely to occur with handling, and the elegance of the appearance of ceramic tiles In this case, excellent characteristics such as surface characteristics and the like can be sufficiently exhibited. Many problems have been solved by the improvements proposed by the present applicant. In particular, when ceramic tiles are continuously used vertically and horizontally, significant improvements have been made in terms of treatment of rainwater that tends to enter from the outside and securing of ease of installation work.

[0006] However, since the front side mating step and the back side mating step where the left and right connections are made are thin in appearance, they seem unreliable if there is a chance to see the connecting point from below for some reason. . In addition, since it is thin in nature, there is a possibility that corners may be chipped during operation. Although slight chipping is practically no problem, it cannot help but detract from commercial value. In particular, when it is in a state where it can be seen, it is easy to lead to distrust in the material and the construction, and there is a possibility that the chance of exhibiting excellent characteristics of the corner is reduced.

[0007]

[Problems to be Solved by the Invention] The present invention structurally reduces the difficulty of handling, which is an inevitable drawback due to the properties of ceramic tiles, and in particular, the occurrence of cracks and missing corners that are likely to occur with handling. In order to improve the appearance of ceramic tiles, such as the aesthetic appearance and surface characteristics, to reduce the chances of corner chipping and improve the reliability of the appearance And add
The purpose is to make it easier to exhibit the graceful appearance and excellent characteristics of ceramic tiles.

FIG. 5 shows the upper and lower joined states when the ceramic tile according to the present invention is used. In use, first, a ceramic tile is positioned at a predetermined position on the base, and the tile is mounted on the base using one of the mounting portions 11. If a hole is formed in the mounting portion 11, the hole is used for mounting with a screw or a nail.
If the mounting portion 11 is a blind hole, a hole is drilled in advance with a drill or the like, or the blind hole is directly pierced using a nail or a screw, and the tile is mounted on the base. The tile is then completely fixed to the substrate using another attachment, also using nails or screws. In the lateral direction, the back side matching step 42 of the second tile is superimposed on the front side matching step 32 of the first ceramic tile, so that the positioning is continuous. Become. At this time, the vertical direction
If it is completely matched with the first tile, the front horizontal groove 311 becomes continuous.

Next, the lower joint step 41 on the back surface of the second ceramic tile is replaced with the upper joint step 31 on the surface of the first ceramic tile already fixed.
, And the tip 8 of the first-stage tile already fixed is fitted into the fitting groove 10 to perform positioning. At this time, if the left and right sides are made completely the same as the lower first tile, the front vertical groove 322 of the front side side mating step 32 is continuous. Further, the front lateral groove 311 and the rear lateral groove 411 completely face each other to form a thin tube. When the left and right positions are shifted from the first tile below and fixed, the front vertical groove 322 is not continuous vertically. However, also in this case, the water moving downward through the front vertical groove 322 is discharged to the front side of the lower tile, so that it is possible to prevent the water from entering the back side.

One of the constructions in which the left and right positions are shifted from the lower tiles is a horse-stomping joint. In this case, it is convenient for positioning if there is an indicator that indicates the center of the lower tile in the left-right direction. The sign 14 in FIG.
It is effective in this case to place it in the center of the tile. Also,
The sign 14 can also be used to cut the tile in half by placing it in the center. In this state, one of the attachment portions 11 of the second ceramic tile is used to attach the second tile to the base with nails or screws, and then the other attachment portion is used to attach the second tile to the base. Completely fix the ceramic tiles on the tier. Hereinafter, this is repeated, and the ceramic tile is fixed to the base in the upward direction.

When the first tile and the second tile are successively mounted in the horizontal direction, the front side matching step 32 and the front side notch 320, and the back side matching step 42 6 and the rear-side mating projection 420 has a relationship as shown in FIG. 6, and when the front surface and the rear-side mating portion overlap each other, the rear-side mating projection 420 is formed.
Are fitted into the front side side matching notch 320. Therefore, as shown in FIG. 7, the front and back sides of the joint step are invisible from the front surface, and only the side edges of the left and right tiles appear to be in contact with each other. In addition, from the lower side of the tile, the matching step portion on both the front and back sides is hidden, so that the thickness of the tile can be seen as it is, and it looks as if it were butted from the left and right. However, even if the front end of the mating step on the surface side is torn off, this will not be exposed. Also,
There is no indication of the thickness of the step on both sides.

FIG. 8 and FIG. 9 show a joining state in a conventional manner. As shown in FIG. 8, the cross section of the front side matching step portion and the rear surface side matching step portion is exposed as it is at the lower end of the tile. Therefore, when the joining is performed, it is clear from the lower side that the joining portion is thinner than the other portions but is superposed, and even if the strength is thin, it is easy to give a feeling of anxiety. Also, the presence of the thin portion at the edge of the tile cannot be ruled out that a drop may occur.

[0024]

The ceramic tile according to the present invention, which is constructed and used as described above, is provided with a notch at the lower end of the front side mating step, and protrudes at the lower end of the rear side mating step. The left and right tiles are joined together by overlapping the front and back side steps, and the thickness and condition of the side steps are determined from below. This gives a sense of security and avoids unnecessary worries, as it simply covers the tiles and makes it look as if the thick tiles were butted together. In addition, since the edge of the front-side mating step is substantially moved inward from the outermost end of the tile, the chance of missing the end can be greatly reduced. Further, since the end of the step portion which is determined by the back side portion is increased in thickness, the possibility of chipping can be greatly reduced.

The ceramic tile according to the present invention having such a structure has a structure in which even if water enters the back surface, the flow of the water is smooth, does not stay, and the water easily escapes. It has become. This can be expected not only to facilitate drying, but also to prevent frost damage often seen in cold regions. Further, since the back surface has no corners, it can be well adapted to the base and can form a sufficiently close contact state. In addition, it is easy to remove the mold during manufacturing, and it is possible to smoothly perform the manufacturing operation.
