る。2. Description of the Related Art Conventionally, various kinds of roof tiles have been used to roof the roof of a building. In roof tiles such as clay roof tiles and cement roof tiles, in order to prevent rainwater from entering the roof pile, it is usually A water drain is provided. For example, JP-A-4
The roof tile disclosed in Japanese Patent Laid-Open No. 309646 is designed to substantially increase the protruding height of the water return provided on the rear end (butt) side of the tile main body to prevent rainwater from invading from the overlapping portion. There is.

になっている。Further, the roof tile disclosed in Japanese Patent Laid-Open No. 3-247840 is provided with two or more concave grooves parallel to the surface side along the rear edge of the tile, and the front end side (roofing) of the tile is provided. On the back surface of the eaves side), a ridge corresponding to this groove is formed, and the height of this ridge is lower than the depth of the groove,
The roof tile is raised so that the groove and the protrusion are engaged with each other.

屋根瓦は、水返しが複雑かつ高く設けられているため、
通常の雨水の逆流、あるいは毛細管現象による雨水の瓦
裏面への回り込みは防止できるが、強風下では吹き込み
による雨水の浸入を防止することができない。However, the above roof tile has the following problems. That is, the former roof tile has complicated and high water repelling,
Although it is possible to prevent the normal backflow of rainwater or the infiltration of rainwater to the back surface of the roof tile due to the capillary phenomenon, it is not possible to prevent the infiltration of rainwater due to blowing under strong wind.

を目的としている。On the other hand, in the latter roof tile, since the protrusions and the groove are intermeshed, rainwater does not enter from the front end side of the tile even if strong wind is blown, but the capillary phenomenon causes rainwater to enter. There is a problem that the workability is poor because the roof tiles cannot be adjusted in the roof flow direction. In view of such circumstances, the present invention has an object to provide a roof tile that can effectively prevent infiltration of rainwater into the field side under strong wind and rain, and can easily perform roofing adjustment and has excellent workability. .

部が形成されている構成とした。In order to achieve such an object, a roof tile according to the present invention is provided with rib-shaped leg portions projecting on the back side along the front edge and along the rear edge. And a waterproof rib protruding from the front side of the leg, and at least 10 mm behind the rear edge of the leg and at a position in front of the rear edge of the lower tile in a roofing state, at least 1 in parallel with the leg. When the protrusion of the book protrudes to the back side, and the height of the leg is a, the height of the protrusion is b, and the height of the waterproof rib is c, 1 mm ≦
Each part is formed so that a-b-c≤5 mm and 1 mm <a-b≤5 mm.

The position of the ridge is not particularly limited as long as it is 10 mm or more behind the rear edge of the leg and is in front of the rear edge of the lower tile in the roofing state, but it is 10 mm from the rear edge of the leg. It is preferable to set it to the rear of -40 mm.

Although not particularly limited, it is preferably about 1 to 5.

い。According to the above construction, when a strong wind blows and rainwater blows from the front end side of the roof tile, the rainwater is splashed from the rear end edges of the legs by wind pressure. As for the water droplets that have soared up, if the ridge is provided at a position less than 10 mm from the rear edge of the leg,
The water droplets are not so high at that position, so the water droplets will not be obstructed by the ridges and will wet the back of the roof tiles, causing water droplets to drip and penetrate into the field, but the ridges are more than the rear edge of the leg. Since it is installed at a position 10 mm or more behind and in front of the rear edge of the lower roof tile in a roofing state, it is blocked by the ridges and falls downward. Then, the water drops that have fallen downward do not drop onto the surface of the lower roof tile without fail and never enter the field.

When the height of the waterproof rib is c, 1 mm ≤ a-b-c ≤ 5
Since each part is formed to have a size of mm, the water droplets splashed by wind pressure do not pass through the gap between the upper tile and the lower tile to wet the field, or do not wet the field by the capillary phenomenon. That is, if a-b-c exceeds 5 mm, the water droplets splashed by the wind pressure pass through,
If a-b-c is less than 1 mm, infiltration of rainwater is likely to occur due to the capillary phenomenon.
