Abstract

PURPOSE: To obtain a tile having excellent drainage properties by a method wherein a plurality of trapezoidal-shaped recessed grooves are formed crosswisely in a latticed shape to a rear while drain holes are formed at the crossed sections of the grooves as being penetrated to a surface and the rear, the recessed grooves are communicated and the tile is laid. CONSTITUTION: Approximately trapezoidal-shaped recessed grooves 2 and 3 are crosswisely formed in a latticed shape to the rear of a tile body 1 laid on a road surface, etc., while drain holes 4 are formed at the crossed sections of the grooves as being penetrated to a surface and the rear. The tile bodies 1 are spread all over the levelled road surface, etc., while the end sections of the recessed grooves 2, 3 are communicated with the recessed grooves of the adjacent tiles. Rainwater falling on the road surface is flowed onto the rear from the drain holes 4 and infiltrated into the ground while being dispersed in all directions by the recessed grooves 2, 3 even when the foundations of the tiles 1 are formed of a non-infiltrating material such as concrete, and discharged into the ground from final terminals. Accordingly, the tiles having excellent drain properties can be acquired easily.

Description

Detailed Description of the Invention

[0001]

The present invention relates to tiles,
More specifically, the present invention relates to a tile laid on a road surface for permeating rainwater on the tile surface into the ground.

[0002]

2. Description of the Related Art Today, road tiles are sometimes laid on the road from the viewpoint of aesthetics, but as tiles, generally non-perforated tiles having no holes on the surface or simply passing through the front and back surfaces of the tiles are used. There is a perforated tile that has only rainwater drainage holes.

[0003]

By the way, it is preferable to allow rainwater that has fallen on the road surface to quickly penetrate into the ground.
Especially in the case of heavy rain, it is known to be preferable from the viewpoint of flood prevention in the downstream.

However, when the non-perforated tiles are laid, the rainwater does not drain well because the rainwater permeates into the ground only at the tile joints. Further, in the above-mentioned perforated tile, when the tile base is sand laid, rainwater disperses in all directions from the discharge holes formed in the tile through the sand part, and the drainage effect is good, but when the tile base is cement Since the cement adheres to the entire back surface of the tile, the drain hole is closed, and rainwater that has entered the drain hole is not discharged from the back surface of the tile, which causes the drainage function to be disabled and the intended purpose cannot be achieved.

Therefore, an object of the present invention is to provide a tile having a good drainage property even when it is bonded with a non-water-permeable substrate such as cement.

[0006]

According to the present invention, in order to solve the above-mentioned problems, a vertical groove (2) and a horizontal groove (3) are provided on the back surface of a tile body (1), respectively. ) Is formed so as to penetrate between both side ends of the tile body, and a small discharge hole (4) that penetrates in the front and back direction of the tile body (1) is formed at the intersection of the grooves (2) and (3). To do.

[0007]

As shown in FIG. 4, when the tile body (1) is adhered to the tile body (1) by the underlayer (5) made of a water impermeable material such as cement, the rainwater that falls on the tile body (1) is It flows into the drain hole (4) formed in the tile body (1) and is dispersed from the lower end of the drain hole (4) into the vertical and horizontal grooves (2) and (3). Then, it is permeated and drained into the ground from the tile body (1) at the outermost end that has been laid.

[0008]

Embodiments of the present invention shown in the drawings will be described.
1 is a tile body, which is made of, for example, a porcelain material,
In the example of the figure, it is formed in a square.

Three vertical grooves 2 are formed on the back surface of the tile body 1.
Are formed in parallel with appropriate intervals, and both ends of each vertical groove 2 are open to the tile side surface. Further, three lateral grooves 3 are formed in parallel on the back surface of the tile body 1 with appropriate intervals, and both ends of each lateral groove 3 are open to the side surface of the tile.

As shown in FIG. 3, the cross-sectional shapes of the grooves 2 and 3 are substantially trapezoidal concave grooves. Vertical groove 2
A drain hole 4 penetrating in the front and back direction of the tile main body 1 is formed at each intersection of the horizontal groove 3 and the horizontal groove 3, and the back side of the drain hole 4 communicates with both grooves 2, 3. The drainage hole 4 is formed as a tapered hole whose lower portion expands to improve the formability and drainage property of the hole.

In order to lay the tile body 1 on a road surface or the like, the base is made of sand or is cemented and laid. In the case of sand, the rainwater that has fallen on the surface of the tile body 1 enters the drainage holes 4 and permeates into the sand, and then permeates into the ground.

In the case of cement bonding, the tile body 1 is slightly pressed and bonded to the surface of the cement 5 whose surface is leveled as shown by 4. At this time, cement 5
Of the tile body 1 is in contact with the back surface of the tile body 1 other than the both grooves 2 and 3, and the cement 5 is adhered so as not to block the both grooves 2 and 3, so that the grooves 2 and 3 communicate with the drain hole 4. In addition, the grooves 2 and 3 are in a state in which their open ends are in communication with each other.

Further, the two tile main bodies 1 and 1 adjacent to each other are arranged so that the respective longitudinal grooves 2 thereof are coincident and opposed to each other, and the respective transverse grooves 3 are coincident and opposed to each other. As a result, a series of vertical grooves and horizontal grooves that open at the side ends of the tiles that are laid at the outermost ends are formed on the back side of the tiles that are laid out in large numbers.

Therefore, even if the ground is cement, the rainwater that has flowed into the drain holes 4 formed in each tile body 1 flows into both grooves 2 and 3 from the tile back side opening of the drain holes 4 and goes in all directions. It is dispersed and permeates into the ground from the end of the tile laid at the outermost edge.

[0015]

As described above, according to the present invention, rainwater can be drained well into the ground even if the base of the tile is a water impermeable material, and the intended purpose as a tile for drainage is to be achieved. Can be achieved.
