[0010]

Next, an embodiment of the present invention will be described in detail with reference to the drawings. FIGS. 1 and 2 show an upper surface 12 and a lower surface 13 of a roof tile according to an embodiment of the present invention. The roof tile according to this embodiment has the same basic parts as the tiles shown in FIGS. 7 and 8, and the same parts are denoted by the same reference numerals as those drawings.

The tile body 11 is substantially square made of pottery, concrete, or the like, and has a sigmoidal swell from the crosspiece 26 which is the side surface of the tile body 11 to the insertion portion 27 side. . Therefore, the crosspiece 26 faces downward, and the insertion section 27 faces upward. The roof tiles shown
The corner between the buttocks 14 and the bar 26 and the head 15 and the insertion portion 27
This is a so-called cut-in tile, in which cuts 16 and 17 are provided at the corners. Further, the point that a nail hole 22 is provided near the butt portion 14 and the cut 16 is the same as the above-described conventional roof tile.

In the present invention, in such a roof tile, a groove 23 for fitting the roof tile b is provided in a portion of the lower surface 13 of the roof tile body 11 to be placed on the roof tile b. The tile in the illustrated embodiment is a so-called hanging tile, and as shown in FIG.
Projections 20 and 20 are provided on the bottom part 14 of the lower surface of the unit 1, and a part closer to the head 15 than the projections 20 and 20 is placed on the tile bar b. Therefore, the groove 23 is formed along the direction in which the projections 20 and 20 are arranged and closer to the head. At the end of the groove 23, the aforementioned nail hole 18 is opened.

Further, in the illustrated embodiment, a raised portion 24 is provided at an end of the groove 23 on the insertion portion 27 side so as to face the projection 20 with the groove 23 interposed therebetween. Another protrusion 21 is provided between the two protrusions 20 on the bottom portion 14 of the lower surface of the tile body 11. These projections 2
0 and 21 may be formed continuously as a whole without being separated as shown.

On the other hand, the tile body 1 provided with the grooves 23
1 to avoid a decrease in the strength of FIG.
As shown in (1), a slight build-up 19 is provided on the upper surface side portion of the tile main body 11 corresponding to the groove 23 so that the thickness of the groove 23 portion is not extremely thin. In order to avoid interference between the overlay 19 and the lower surface 13 of the tile main body 11 when the tile main body 11 is overlapped, a shallow cutout 25 is provided on the lower surface 13 on the head 15 side.

FIGS. 3 to 6 show a part of the roof. In FIG. 3 to FIG. 6, a downward slope of the roof is formed from the top to the bottom, and the slope is orthogonal to the slope on the roof field a. A long bar with a rectangular cross section in the direction is attached as a tile bar b. In FIG. 3, only one tile b is shown.
Are mounted in parallel at regular intervals at intervals of arranging the tile bodies 1 along the slope of the roof.

The butt portion 14 on the back surface of the tile main body 1 is placed on the tile bar b, the tile bar b is fitted into the groove 23, and the projection 2
The tiles 0 and 20 are hung on the tile b, and the tile is placed on the field a. These roof tiles are tiled vertically and horizontally on the field a, and the head 15 is attached to the bottom 1 of the tile adjacent to the roof along the slope of the roof.
4, the bar portions 26 are respectively superimposed on the insertion portions 27 of the tiles adjacent in the longitudinal direction of the tile b. The corner cut 17 between the head 15 and the insertion portion 27 is aligned with the corner cut 16 between the buttocks 14 and the crosspieces 26 of the roof tiles adjacent diagonally upward. For some of the tile main bodies 11, nails c (see FIGS. 4 and 5) inserted through the nail holes 22 are driven into the above-mentioned tile crosspieces b to fix the tile main bodies 11 to the roof.

As shown by an arrow in FIG.
When the strong wind blows from the side, the crosspiece 26 receives the wind pressure. However, the tile main body 11 is not easily displaced because the roof tile b is fitted in the groove 23. Further, when the tile main body 11 is driven into the tile bar 16 through the nail c through the nail hole 22, the fixing of the tile main body 11 to the tile bar b becomes more reliable. That is, since the lifting of the tile main body 11 is suppressed, the groove 23 does not come off from the tile crosspiece b, and the rotation of the tile main body 11 in the arrow direction is prevented.

Further, as in the illustrated embodiment, a protruding portion 24 is provided at the end of the groove 23 on the side of the insertion portion 27 so as to face the projection 20 with the groove 23 interposed therebetween, or When another protrusion 21 is provided between the tiles, the groove 23 is not easily removed from the tile crosspiece b even if the side of the crosspiece 26 of the tile main body 11 where the nail c is not driven is slightly lifted by the wind. For example, FIG.
And as shown by a two-dot chain line in FIG.
Even if the tiles 1 are raised, the raised portions 24 and the projections 21 are still hung on the tile rails b, so that the tile main body 11 does not deviate in the plane direction. It is fitted to the bar b.

In the above-described embodiment, the present invention is applied to ordinary roof tiles. However, the present invention is similarly applied to other roof tiles, for example, snow-roof tiles and shingle roof tiles. It goes without saying that you can do it.

[0020]

As described above, it is possible to provide a roof tile that can withstand the strong wind from the side of the roof of the tile main body and does not easily displace the tile main body. The effect can be obtained such that it can be minimized and the roof does not need to be repaired after the storm.
