Description

[Detailed description of the invention] The present invention relates to an improvement of a ridge tile, and relates to a ridge tile provided with a ventilation passage.

In recent years, with the spread of aluminum sash, indoor spaces have become airtight, resulting in dew condensation in the attic and inside the exterior walls in the winter, reducing the durability of buildings and causing the attic to be illuminated by the sun in the summer. A problem arose in that air was trapped, reducing livability.
In order to prevent this, conventional construction methods involved creating ventilation holes in the gable walls of houses, and in hipped houses, providing ventilation channels that opened in the eaves. However, in the former case, the ventilation holes were not large enough to allow rainwater to blow in through the ventilation holes, causing rain build-up. In addition, the ventilation holes in the latter case are located further below the ventilation passage in the attic, making it difficult to provide effective natural ventilation.

An object of the present invention is to eliminate the above-mentioned drawbacks and provide a ridge tile provided with a ventilation path for discharging the air in the attic led to the ridge into the outside air through a gap in the ridge tile.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In Figures 1 to 6, the ridge tile is the body part 10.
The outer fitting part 20 and the inner fitting part 30 are integrally formed.
Thus, the body 10 has a half-cylindrical shape, and at the center of its inner surface there is a first hole extending from the inner fitting part 30 to the outer fitting part 20 along the longitudinal direction (horizontal direction in FIG. 2) along the length direction of the tile. A back groove 11a is provided. 12 is a nail hole.

The outer fitting part 20 consists of a half-cylindrical part 21 extending along the length direction of the tile of the body part 10, an inner flange part 22 formed at one end of the half-cylindrical part 21, and a boundary part 23 between the body part 10 and the body part 10. The inner flange portion 22 is connected to the body portion 10 of the adjacent tile.
It has an inner circumferential surface 22a along the surface of the tile, and is provided with a notch 22b extending in the radial direction from the inner circumferential surface 22a and passing through the tile in the length direction. The back surface of the boundary part 23 has a back lateral groove 24b communicating with the first back groove 11a and extending in the circumferential direction, and a back inclined groove 24a extending radially from the back lateral groove 24b toward the inner surface of the semi-cylindrical part 21. A second back groove 24 is provided.
A surface groove 33 along the width direction of the ridge tile is provided on the outer periphery of the inner fitting part 30.
One or more (two in this example) protrusions 3 are inserted through the
1 and 32 are provided. And these first protrusions 3
1. The second protrusion 32 has a plurality of first notches 31a and a plurality of second notches 3 that penetrate in the length direction of the ridge tile, respectively.
2a is provided. These respective first notches 3
1a and the second notch 32a are arranged so as not to overlap with each other in the length direction of the ridge tile.

The second protrusion 32 is provided with diagonal protrusions 34 extending toward the outer fitting portion of the ridge tile at both hem portions of the ridge tile, and the surface groove 34 is connected between the upper side surface and the lower end of the first protrusion 31.
A diagonal drainage groove 35 that is continuous with 3 is formed.

The surface 30a of the internal fitting part 30 is higher than the surface of the body part 10.

When the ridge tiles are used, they are arranged in such a manner that the protrusions 31 and 32 of the inner fitting parts 30 of adjacent tiles are positioned inside the half cylindrical part 21 of the outer fitting part, as shown in Figure 5. At this time, a space C is left between the inner flange 22 and the first protrusion 31. And the second notch 32a,
The first notches 31a and the inner flange part notches 22b are arranged alternately in the tile length direction so as not to overlap, thereby forming a meandering air path from one side to the other side in the ridge length direction.

Therefore, in a ridge roofed in this manner, the air introduced from the attic to the back surface of the ridge tile by a structure other than the one in the present invention will flow around the first roof tile as shown by arrow B in the fifth figure.
The second notch 32 passes through the back groove 11a and the second back groove 24.
It enters the surface groove 33 from a, further meandering, and enters the first notch 3.
1a and reaches the large gap space C between the first protrusion 33 and the inner flange portion 22. And notch 22b
It is then discharged into the outside air.

Wind and rain from the left side in FIG. 6 enters the space C through the notch 22b and is decelerated, and the first protrusion 31
Its progress is stopped by the groove 33 through the first notch 31a, and its progress is stopped by the second protrusion 32. Moreover, since the surface 30a of the inner fitting part 30 is made higher than the surface of the body part 10, the inflow of rainwater is further prevented.

In this way, wind and rain are gradually slowed down and prevented from advancing, thereby preventing them from entering the building. However, in the unlikely event that rainwater flows in, it is discharged down to one side of the ridge tile through the surface groove 33 and the diagonal drainage groove 35.

Note that an air passage (not shown) may be provided on the side of the ridge beam that supports the ridge tile without providing the first back groove 11a of the body. Alternatively, the second back groove of the boundary part 23 may not be provided, and a gap may be left between the inner surface of the boundary part 23 and the end surface of the inner fitting part of the adjacent ridge tile.

Further, the body portion 10, the outer fitting portion 20, and the inner fitting portion 30 do not have to be half cylindrical, but may be half rectangular cylinders with arcuate corners or half ellipsoidal cylinders. Moreover, the notch 22b may be formed downward instead of facing in the radial direction.

As described above, the ridge tile of the present invention has protrusions and inner flanges at the overlapping parts of adjacent tiles, and cutouts are provided in these to form zigzag air passages, making it possible to actively ventilate between the ridge tiles. The air passage can prevent rainwater from blowing in from the outside. This eliminates the phenomenon of condensation inside the building's exterior walls, improving the durability of the building.
