Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to improvements in ceramic tiles.

(Prior Art) When adhering this type of ceramic tile to a wall surface, adhesive mortar is used, but there is a risk that the tile may slide off due to its own weight before the adhesive mortar hardens.

Therefore, in order to prevent the tiles from slipping and falling, there are strip-like protrusions on the back surface of the tiles, so-called parallel protrusions with the so-called soles set horizontally.

However, if the shape of the tile is square and the pattern on the surface has no directionality, and the soles are oriented in a fixed direction as mentioned above, the back side of each tile must be checked when pasting the tiles. However, it is inconvenient that you have to paste it. This is because the sole of the foot in a certain direction is effective in preventing slipping off if it is oriented horizontally, but it cannot be prevented from slipping off if the sole is oriented vertically. This is because there is no

In addition, as a means to solve the above-mentioned problems, it may be possible to form the sole in a lattice shape, but in this case, there is no escape of air within the closed lattice, so the attachment should be done smoothly. It has problems such as being difficult to form and firmly adhering.

(Problems to be Solved by the Invention) The present invention provides a tile with a non-directional sole that can be attached without checking the direction of the sole when pasting the tile and can prevent slippage. It is in.

(Means for Solving the Problems) The means of the present invention to solve the above problems is to divide the back side of the square tile body into four blocks in a cross shape, and attach a strip-shaped sole to each block. A plurality of blocks are slanted and protruded in parallel so that the soles of adjacent blocks form a substantially eight-figure shape in plan.

(Function) With the above configuration, the sole of the square tile is placed in a direction that prevents displacement in the vertical direction no matter which direction it is installed. There is no danger of

(Example) An example of the present invention will be described below based on the drawings. Figure 1 is a back view of a ceramic tile in which a band-shaped sole B is integrally formed on the back side of a square tile body A. .

The sole foot B divides the back surface a of the tile body A into four blocks a ₁ , a ₂ , a ₃ , and a ₄ , and the tile body A is divided into four blocks a ₁ , a 2 , a _{3 ,} and a 4 . A plurality of blocks (5 blocks per block in the drawing) protrude outward from the center in parallel at an angle of 45°, and are arranged so as to form a substantially eight-figure shape in plan with the soles B of adjacent blocks.

That is, the sole B of block a ₁ is connected to blocks a ₂ and a _3.
Sole foot B of block a ₂ and sole foot B of block a ₁
and the sole feet of block a ₄ , the sole foot B of block a ₃ is flat with the sole feet of blocks a ₁ and a ₄ , and the sole foot B of block a ₄ is flat with the sole feet of blocks a ₂ and a ₃ , respectively. They are arranged in a roughly eight-figure shape.

Also, the length of the sole B in each block a ₁ to _{a 4} ,
The width and the groove width between the soles are determined by considering the thickness of the tile to be molded and the height of the soles, and the firing shrinkage changes due to local pressure differences during dry press molding. To prevent distortion of the product shape after firing. For example, sole feet b ₁ placed diagonally in each block a ₁ to _{a 4}
are long and wide, and the soles b ₂ placed on the outside of the soles b ₁ are shorter in length than soles b ₁ , so the width is also smaller, and furthermore, the width is made smaller in the longitudinal direction of each sole foot B. Both ends flow into the bottom in an arc shape. As a result, the shape is determined so that the area ratio of the sole B part (the part with less tightness) to the bottom surface (the part with stronger tightness) in a unit area is determined to be constant.

FIG. 4 shows another example of the arrangement of the sole feet B, which are long and wide on the diagonal line connecting the points where each side of the tile body A intersects with the division line that divides the back surface of the tile body A into a cross shape. Place the wide sole foot b ₁ ′ of
sole foot on the outside of b ₁ ′, which is shorter and narrower than b ₁ ′
b ₂ ′ are arranged parallel to each other at intervals, and the soles of adjacent blocks a ₁ ′ to _{a 4} ′ each form a substantially eight-figure shape in plan.

In addition, in each of the above-mentioned embodiments, the soles are not connected to each other, and the grooves between the soles are open inwardly and outwardly.
This allows air to escape smoothly during tiling.

(Effects) The ceramic tile of this invention divides the back side of the square tile body into four blocks in a cross shape.
Each block has a plurality of oblique strip-like soles that protrude parallel to each other so that the soles of adjacent blocks form an approximately eight-figure shape in plan, so you can tell which direction the tile is facing. The sole feet on the back side are also positioned in a direction that prevents vertical displacement.

Therefore, the conventional problem of having to look at the back side of each tile to confirm the direction of the sole when pasting the tiles can be solved, and the pasting work can be done quickly and tiles can be reliably prevented from falling off. We can provide ceramic tiles.
