Description

[Detailed explanation of the idea] The present invention relates to a ridge structure.

In recent years, as houses have become airtight due to the spread of aluminum sash, dew condensation occurs in the attic and inside the exterior walls in the winter, reducing the durability of buildings and causing air heated by the sun to leak into the attic in the summer. A problem arose in that the build-up deteriorated livability. Conventional construction methods to prevent this were to provide ventilation holes in the gable walls of houses, and in hipped houses, provide ventilation channels that opened in the eaves.

However, in the former case, it was not possible to prevent rainwater from blowing in, which could cause rain build-up, making it impossible to provide a sufficient opening area for ventilation. In the latter case, the outdoor opening is located below the ventilation channel in the attic, making it difficult to provide effective natural ventilation.

The object of the present invention is to eliminate the above-mentioned drawbacks and provide a ventilation ridge structure that guides the air in the attic to the ridge and naturally discharges it from this part to the outside air.

In order to achieve this purpose, the structure of the present invention is as follows. That is, a plurality of ridge pier brackets are arranged with gaps in the length direction of the ridge, roof tiles are placed on the roof board with a waterproof sheet interposed therebetween, the ridge pier is supported by the ridge ridge brackets, and the ridge pier is In a ridge structure in which a ridge tile is fixed covering a ridge beam, a downward gutter-shaped ventilation fitting having a ventilation hole penetrating vertically between the ridge tile and the ridge tile is placed over the ridge beam. and the ridge tile placed on the ventilation fitting has a body part,
It has an outer fitting part and an inner fitting part, and the outer fitting part consists of a half-tube part, an inner flange part formed at one end thereof, and a boundary part with the body part, and the inner flange part is provided with a notch that penetrates in the length direction of the ridge tile, one or more protrusions are provided on the outer periphery of the inner fitting part along the width direction of the ridge tile, and the protrusions are provided with a notch that penetrates in the longitudinal direction of the ridge tile. , when two adjacent ridge tiles are arranged with the protrusions of their inner fitting parts located inside the semi-inner cylindrical part of the outer fitting part, the notches of the inner flange part and the notches of the protrusions form the ridge tiles. The tiles are arranged alternately so that they do not overlap in the length direction, and the roof boards have a gap in the ridge portion that allows ventilation from bottom to top, and the waterproof sheets on both sides of the ridge are arranged close to the ridge-side end surface of the tile. It stands up, and its end is located inside the hanging part of the ventilation fitting.

An embodiment of the present invention will be described below based on the drawings.

As shown in the first diagram, the ridge of the present invention has a roof board 1 stretched over the upper surface of the rafters 2 with a ventilation gap S in the ridge part, and a ventilation gap T laid on the roof board 1. a waterproof sheet 3 such as asphalt roofing extending upward; a ridge pier support 6 having a leg 61 fixed to the shedding board 1 between the waterproof sheet 3 and the shedding board 1; It is composed of a ridge beam 7 which is long along the ridge direction and supported by the ridge beam receiving metal fitting 6, and a downward gutter-shaped ventilation fitting 8 which is placed to cover the ridge beam 7. The top of the ridge is covered with a ridge tile 9 having a ventilation groove 911 along the length of the ridge at the center of the back side.

Thus, a plurality of ridge support metal fittings 6 are attached at intervals in the ridge length direction, and the ridge ridge 7 is fixedly supported by nails 6a.

As shown in the second figure, the ridge beam 7 has a ventilation groove 72 on the top surface.
and a raised part 71 are formed, and the raised part 71 supports the ventilation fitting 8.

As shown in the third figure, the ventilation fitting 8 has a horizontal top part 81, a shoulder part 82 that slopes downward in the left-right direction (direction perpendicular to the ridge), and a lower part 83 that extends vertically downward from both ends of the shoulder part 82. The horizontal top portion 81 is in the form of a gutter, and a large number of ventilation holes 81a are provided through the horizontal top portion 81 along the length direction. This ventilation hole 81a is also used as a nail hole for a nail 9a that fixes the ridge tile 9 to the ridge shoal 7.

A tile beam 4 is fixed to the upper surface of the ridge side end of the roof board 1 via a waterproof sheet 3, and tiles 5 are covered. The gap between the ridge cover tile 9 and the tile 5 is sealed with mortar 10.

The waterproof sheets 3, 3 on both sides of the ridge stand up close to the ridge-side end surface of the tile 5 and between the receiving metal fitting 6, and their ends are located inside the hanging part 83 of the ventilation fitting 8. This prevents the tarpaulin from hanging downward. 11 in FIG. 1 is a ridgepole.

The ridge tile 9 has a body part 91, an outer fitting part 92, and an inner fitting part 93 which are overlapped as shown in the fifth and sixth figures, and the tile nail 9
It is fixed to the ridge beam 7 by a. A first back groove 91 extending from the inner fitting part 93 to the outer fitting part 92 is formed on the inner surface of the body part 91.
1 is provided. The external fitting portion 92 is the half-split cylindrical portion 9
21 and an inner flange portion 9 formed at one end thereof.
22 and a boundary portion 923 between the body portion 91 and the body portion 91 . The first back groove 91 is formed on the inner surface of the boundary portion 923.
A second back groove 924 is provided which communicates with the cylindrical half portion 921 and extends toward the inner surface of the half cylindrical portion 921. The inner flange portion 922 is provided with a notch 922b that penetrates in the length direction of the ridge tile 9. On the outer periphery of the internal fitting part 93, one or more (two in this embodiment) protrusions 931, 932 are provided along the width direction of the ridge tile 9. These protrusions 931 and 932 are provided with cutouts 931a and 932a that penetrate in the longitudinal direction of the ridge tile, respectively.
Then, the two adjacent ridge tiles are connected to their inner fittings 9.
When the protrusions 931 and 932 of No. 3 are positioned inside the half-cylindrical part 921 of the outer fitting part 92, the notch 922b of the inner flange part 922 and the protrusions 93
The 1,932 notches 931a and 932a are arranged in the intersecting tile so that they do not overlap in the length direction of the ridge tile 9.

The operating state of the above structure will be explained.
As shown by the arrow F, the airflow rising to the ridge of the attic passes through the gap S between the left and right sheathing boards 1, 1 that sandwich the ridge, and the gap t between the waterproof sheets 3, 3, and is guided to the waterproof sheet for ventilation. It reaches the bottom of the metal fitting 8, and the ridge pier 7
It flows through the ventilation hole 81a through the ventilation groove part 72 of
It is guided to the lower surface of the ridge cover tile 9. The air flow is further transmitted through the grooves 911, 924 and the notches 932a, 93 of the tile 9.
It is released into the outside air through the 1a notch 922b. Wind and rain blowing into the inside of the ridge tile is slowed down and prevented by the protrusions 31 and 32.

Even if a gap occurs between the tile 5 and the ridge tile 9 and rainwater infiltrates, the rising edge of the waterproof sheet 3 is placed inside the hanging part 83 of the ventilation fitting 8, so the rainwater will leak into the roofing board. It never reaches 1.

FIG. 4 shows another embodiment showing a state in which the ventilation fitting 8 is assembled when the ridge beam 7 does not have a ventilation groove, and in this case, the ventilation hole 82a of the ventilation fitting 8 is provided in the shoulder portion 82.

Note that the ventilation fitting may be omitted. Further, in the ridge tile 9 of the above embodiment, notches are provided in the inner flange portion 922 of the outer fitting portion 92 and the protrusions 931, 932 of the inner fitting portion 93 to facilitate ventilation. The wrapping tile is not limited to this type, and may have a shape commonly used in the past, and in this case, air inside the ridge flows out to the outside air through gaps inevitably left between adjacent tiles.

Since the building of this invention has the structure as described above,
The air in the attic rose to the ridge and was easily exhausted to the outside air, allowing natural ventilation. Therefore, even in wooden houses in cold regions, condensation does not occur and the durability of the buildings is improved. In addition, the ridge tiles are provided with 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 through the ridge tiles. The air passage can prevent rainwater from blowing in from the outside. In addition, the waterproof sheet stands up close to the edge of the roof tile, and its end is located inside the hanging part of the ventilation fitting, which prevents the waterproof sheet from hanging downward.
Good waterproof performance is guaranteed.
