DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to the drawings.

FIGS. 1 to 5 are views for explaining a crown tile 10 according to an embodiment of the present invention. FIG. 1 is a front view, FIG. 2 is a rear view, and FIG. 3 is a side view. , FIG. 4 is a perspective view,
FIG. 5 is a bottom view.

The roof tile 10 is, for example, as shown in FIG.
In a ridge that is a horizontal portion where a pair of inclined roof surfaces intersect, it is arranged in a row in a state of straddling both sides of the pair of inclined roof surfaces and overlapping both ends.
The roof tile 10 has an inverted U-shaped roof body 18 having a canopy portion 12 having an arcuate cross section, that is, a relatively shallow partial cylindrical shape, and a pair of hanging portions 14 and 16 hanging from both sides of the canopy portion 12. Is equipped with. The pair of hanging portions 14, 1
6 is slightly opened so as to be separated from each other as it goes downward, and the lower end surface 2 inclined along the inclined roof surface 2
0 and 22 are provided.

The roof tile body 18 extends along the edge of one end portion (the left end portion in FIG. 3) of the canopy portion 12 and the canopy portion 12 thereof.
A string portion 24 protruding upward from the outer surface of the roof by a predetermined height H and protruding from an edge of one end of the outer surface by a predetermined width W in the longitudinal direction of the roof tile body 18, that is, the longitudinal direction.
Are integrally formed on the outer surface of the canopy portion 12. In order to provide a watertight function, the cord portion 24 is, as shown in FIG. 6, the other end portion of the canopy portion 12 ′ of the other roof tile 10 ′ adjacent to the one end portion side (the left end portion side in FIG. 3). It is provided to be stacked on top of.

The roof tile body 18 has an outer portion of a pair of end faces formed by a pair of hanging portions 14 and 16 of the inverted U-shaped end face of one end portion (the left end portion in FIG. 3) of the roof tile body 18. From the above, longitudinal protrusions 26 and 28 are respectively formed to protrude in the column direction of the crown tile 10, that is, the longitudinal direction, by a predetermined amount D set to be sufficiently smaller than the protrusion width dimension W of the string portion 24. The elongated protrusions 26, 28 are formed in the hanging portions 14, 1,
The width dimension T of 6 is formed in a continuous longitudinal shape.

Further, the roof tile main body 18 has a pair of end faces composed of a pair of hanging portions 14 and 16 of the inverted U-shaped end faces of the other end portion (right end portion in FIG. 3) of the roof tile main body 18. Elongate notches 30 and 32 are formed by cutting the inner portion of the above in the column direction by a predetermined amount E, respectively. The longitudinal notches 30 and 32 are also formed in a longitudinal shape continuous over the entire width dimension T of the hanging portions 14 and 16, and the longitudinal protrusions 26 and 28 are fitted therein. . Therefore, the protrusion dimension D of the longitudinal protrusions 26 and 28 in the column direction is set to a value equal to or smaller than the depth E of the longitudinal notches 30 and 32 in the column direction and arranged in the column. In the roof tile 10 and the roof tiles 10 ′ and 10 ″ adjacent to the one end side and the other end side thereof, the hanging portions 14, 16 and the hanging portions 14 ′, 16 ′ and 14 ″, 1
A gap is not easily formed between the 6 '' and the 6 ''.

The crown tile 10 constructed as above is shown in FIG.
Further, as shown in FIG. 7, the roof tiles 10 'and 10''adjacent to the one end side and the other end side thereof are arranged in a column so that their mutual end portions overlap each other. That is, the predetermined crown tile 10
The string portion 24 provided at one end of the roof tile is overlapped on the end portion of the canopy portion 12 'of the roof tile 10' adjacent to the one end side thereof, and is attached to one end portion of the predetermined hanging portions 14 and 16 of the roof tile 10. The roof tile 10 'having the elongated protrusions 26, 28 provided adjacent to one end side thereof.
The watertight function is enhanced by being fitted into the longitudinal notches 30 'and 32' provided at the other ends of the hanging portions 14 'and 16'.

FIG. 8 shows the roof tiles 10 among the roof tiles 42 laid on the rails 40 on each roof surface in a state where the crown roof tile 10 straddles the ridge which is the intersection line position of the pair of inclined roof surfaces. It shows a state of being placed on the cross-piece 42a located at the top.

As described above, according to this embodiment, the pair of hanging portions 1 of the inverted U-shaped end surface of the one end of the roof tile body 18 is used.
Long protrusions 26 and 28 formed by projecting an outer portion of a pair of end faces composed of 4 and 16 in the column direction by a predetermined amount D, and an inverted U-shaped end face of the other end of the roof tile body 18. The longitudinal notches 30 and 3 formed by notching the inner portions of the pair of end surfaces formed by the pair of hanging portions 14 and 16 in the column direction by a predetermined amount E.
The two and the two are fitted to each other when the crown tiles 10 are arranged in a row, so that a high watertight function can be obtained without forming the string portion 24 on the hanging portions 14 and 16. Moreover, since the hanging portions 14 and 16 are formed, even if the slope of the roof surface is relatively steep, the roof tile or the like does not come into contact with the inner surface of the roof tile 10 and does not lift it. 10
A gap is less likely to be formed between the roof tile and the roof tile 42a.

By the way, the conventional roof tile 58 shown in FIG. 9 is a ridge which is a horizontal ridge portion where a pair of inclined roof surfaces intersect with each other. Are arranged in a row in a state of straddling the uppermost roof tile 62 and having both ends overlapped with each other. That is, the watertight function is enhanced by providing the string portion 64 at one end portion so as to be overlapped with the other end portion of the other adjacent roof tile 58. Conventionally, such a crown tile 58 has a partially cylindrical shape in which a cross section is relatively shallow and curved, and a plurality of relatively flat tile tiles 66 called “oshishi” are piled up while being prepared using soil. Since it is placed, when it is attempted to reduce the number of the roof tiles 66 for the purpose of facilitating the roofing work and the like, and it is attempted to provide the hanging portions on both sides of the conventional roof tile 58, the hanging portions are formed. It was difficult to provide a cord portion on the design, and the watertight function deteriorated. If the roof surface is relatively steep, the roof tile 5
There is also a problem that a gap occurs between the crown tile 58, the cross tile 62, and the tile tile 66 placed on the tile tile 58 when the tile tile 66 or the like comes into contact with and lifts the tile tile 66 on the inner surface of the column 8. Of.

Although not described one by one, the present invention can be variously modified and changed within the knowledge of those skilled in the art.
