DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof tile, and more particularly to a roof tile used in the roof tile.

[0002]

2. Description of the Related Art A roof tile is generally composed of a flat tile and a round tile. Prevents entry.

FIG. 7 is a plan view showing a conventional flat tile 1 of such a roof tile.

In this figure, a flat roof tile 1 has a main body 3 having an arcuate cross section also called a valley or a flat surface, and a pair of right and left protruding from the surface of the main body 3 at both lower ends of the main body 3. Drainers 5a and 5b are provided. The pair of drainers 5a, 5b is for preventing rainwater from flowing below the round tile by overflowing from the left and right sides of the main body 3.

When the flat roof tiles 1 are installed, the plurality of flat roof tiles 1 are overlapped with each other by only the roofing feet H shown in FIG. Thus, the drainers 5a and 5b are in a continuous state, and it is possible to prevent rainwater from entering.

[0006]

However, there is a problem that even under the strong wind and rain conditions, even the above-mentioned configuration cannot completely prevent rainwater from entering.

That is, the flat roof tile 1 shown in FIG.
Although the overflow of rainwater is prevented by 5b, when the wind and rain is strong, the lower end faces 7 of the drainers 5a and 5b of the flat tile 1 located above the flat tile 1 overlapped with the flat tile 1 located below and the flat tile located below. Rainwater infiltrates through a gap in the contact portion between the drainers 5a and 5b of the roof tile 1 and the upper end surfaces 9 thereof. This rainwater, together with the action of the capillary action due to the surface tension of the rainwater, reaches the roof placed below the round tile.

[0008] If rainwater enters the roof, the freezing of the rainwater causes problems such as damage to the tiles and corrosion of the roof.

[0009] The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a roof tile capable of completely preventing rainwater from entering.

Upper end surfaces 19 of a pair of drainers 13a, 13b
As shown in FIG. 1, a and 19b have a shape in which the central portion direction of the main body 11 is inclined downward in a plan view, in order to improve the drainage state of rainwater. Drainer 13
a, 13b have lower end surfaces 21a, 21b,
It is inclined at the same angle as 19b.

The lower portions of the pair of drainers 13a and 13b are chamfered for installation of a round tile 30 described later, and the drainers 13a and 13b are separated from the center of the main body 11 as shown in FIG. It has a substantially trapezoidal shape when viewed from the side. Further, on the surface of the drainers 13a and 13b, a plurality of grooves 23 for fixing the roofing soil 31 described later are recessed.

The pair of projections 15a, 15b are
3a, 13b are connected to upper end surfaces 19a, 19b,
Like the upper end surfaces 19a and 19b of the drainers 13a and 13b, the upper end surfaces 16a and 16b of the protruding portions 15a and 15b are inclined downward in the center direction of the main body 11 in a plan view in order to improve the drainage state of rainwater. It has a shaped shape.

As shown in FIG. 3, the pair of recesses 17a and 17b accommodate the projections 15a and 15b therein when the flat tiles 10 overlap each other as shown in FIG. It is required that the generation of a gap between the front surface and the rear surface of the flat tile 10 located above can be prevented. Therefore, the concave portions 17a, 17b are provided with the respective convex portions 15a, 15b.
Needs to be larger than the outer shape of the projections 15a and 15b so that can be stored.

In this embodiment, each of the recesses 17a and 17b is formed on the entire back surface of each of the drainers 13a and 13b, and the shape thereof is as shown in FIG. 1 (b). It has an arcuate shape facing the surface direction. In this embodiment, such a shape is adopted because the thickness of the drainers 13a and 13b is made substantially constant, thereby preventing distortion when baking flat tiles in the unglazed state, and improving each convexity. This is for preventing the infiltration of rainwater due to the capillary phenomenon by reducing the contact area with the portions 15a and 15b.

When the flat tiles 10 are overlaid, as shown in FIG.
a, 17b, the surface of the flat tile 10 located below and the back surface of the flat tile 10 located above are in close contact. In addition, the drainers 13a and 13b of each flat tile 10 are in a continuous state. At this time, as described above, each drainer 1
3a and 13b have a substantially trapezoidal shape when viewed from the center of the main body 11, so that the continuous drainers 13a and 13b have a constant height from the surface of the main body 10 at any position. Will have.

Next, a state in which the flat tile 10 is laid up will be described. FIG. 4 is a perspective view showing a state in which the flat tile 10 is overlaid and roofed together with one round tile 30, and FIG. 5 is a partial front view showing a part of the tile in an enlarged manner.

As shown in these figures, when the roof is laid up, rows of a plurality of flat tiles 10 which are overlapped with each other only with the roofing feet H shown in FIG. 1 are arranged side by side. You. Then, the roof tiles 31 are laid on the adjacent flat tiles 10 above the drainers 13a and 13b, and the round tiles 30 are installed above the roof tiles 31.

In this embodiment, the flat roof tile 1
Since the water drainers 13a and 13b protruding from the surface of the main body 11 are provided, it is possible to reduce the required roofing soil 31 in a smaller amount. Further, since a plurality of grooves 23 for fixing the roofing soil are formed on the surfaces of the drainers 13a and 13b,
The roof can be easily piled up.

In the rainfall state, the rainwater that has reached the round tile 30 and the flat tile 10 flows down along the surface of the main body 11 of the flat tile 10. Depending on the amount of rainfall, the rainwater reaches the right and left ends of the main body 11, but this rainwater is blocked by the drainers 13 a and 13 b and does not overflow from both ends of the flat tile 10.

In particular, in this embodiment, since the drainers 13a, 13b have a substantially trapezoidal shape when viewed from the center of the main body 11, the continuous drainers 13a, 13b Even at the position, it has a certain height from the surface of the main body 10, and it is possible to effectively prevent overflow of rainwater.

The shape of the drainers 13a and 13b viewed from the center of the main body 11 in a side view is not limited to a substantially trapezoidal shape, but may be a rectangular shape. In short, the continuous drainers 13a, 13b can be used in any position.
It is sufficient to have a shape having a certain height from the surface of. The certain height is appropriately set according to the amount of precipitation, etc., and is preferably at least about 10 mm based on the average amount of precipitation in Japan. Therefore,
In the above embodiment, the minimum height of the substantially trapezoidal shape of the drainers 13a and 13b in a side view as viewed from the center of the main body 11 may be about 10 mm.

In the above-described state, when the wind and rain become intense, the rainwater is removed from the upper end surfaces 19a and 19b of the drainers 13a and 13b of the flat tile 10 located below and the upper ends of the flat tiles 10 overlapping each other. Drainers 13a, 13b of the flat roof tile 10 and lower end surfaces 21a,
1b, 25, and enters into the downward direction of the roofing soil 31 from the gap of the contact portion. However, the rainwater is blocked by the convex portions 15a and 15b provided on the flat tile 10 located below. Therefore, according to the flat roof tile 10, it is possible to completely prevent rainwater from entering.

The rainwater that has reached the convex portions 15a and 15b moves toward the surface of each of the convex portions 15a and 15b by capillary action. However, in this embodiment, the drainers 1 in which the protrusions 15a and 15b are located thereabove.
3A and 13B, since it is configured to be housed in the concave portions 17a and 17b on the lower surface, there is no contact between the convex portions 15a and 15b and the roofing soil 31, and rainwater enters the roofing soil 31 via the convex portions 15a and 15b. Never.

In order to prevent rainwater from overflowing from each of the projections 15a, 15b due to particularly strong wind and rain or capillary action, the height of the projections 15a, 15b from the main body 11 should be a certain value or more. preferable. The height of the projections 15a, 15b is appropriately set according to the amount of precipitation, etc., and may be at least about 10 mm based on the average amount of precipitation in Japan.

In this embodiment, as described above, each of the recesses 17a, 17b is provided with each of the drainers 13a, 1b.
3b is formed on the entire back surface of the main body 1b.
Drainers 13a, 1a in side view as viewed from the center of 1
3b has an arc shape facing the surface direction. For this reason, the back surfaces of the drainers 13a and 13b in which the concave portions 17a and 17b are formed are in contact with the front surfaces of the convex portions 15a and 15b only at a part thereof. Therefore, no capillary phenomenon occurs between the back surfaces of the drainers 13a, 13b and the front surfaces of the projections 15a, 15b, and it is possible to more effectively prevent infiltration of rainwater.

Next, a second embodiment of the present invention will be described. FIG. 6 is a perspective view showing a roof tile 40 according to the second embodiment of the present invention. In this figure, the same members as those in the first embodiment are denoted by the same reference numerals, and detailed description is omitted.
