Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a roof ventilation structure that ventilates the attic through the ridges of the roof, and specifically relates to a technique for increasing ventilation efficiency.

[Background technology]

Conventionally, the ventilation structure of a roof is such that the ridge ventilation opening installed at the top of the ridge is covered with a rain-cutting board that spans the ridge, a vent is provided that penetrates the rain-cutting board from above and below, and the upper part of the rain-cutting board is covered with a ridge tile. The ridge tile was covered with a tile ventilation opening located at a different location than the ventilation opening in the rain cutter. However, with this configuration, the ridge tiles with an approximately inverted U-shaped cross section are connected to form a tunnel-like space, and since both ends of this tunnel-like space are open, it is difficult to access from the attic. There was a problem that the upward flow reaching the tile ventilation openings was suppressed, resulting in poor ventilation efficiency.

[Purpose of invention]

The present invention was developed in view of the above problems, and its purpose is to provide a roof ventilation structure that can easily generate upward flow and improve ventilation efficiency through simple improvements. be.

[Disclosure of invention]

(Structure) That is, in the present invention, a ridge ventilation opening 1 provided at the top of the ridge is covered with a rain-cutting plate 2 that spans the ridge, a ventilation opening 3 is provided that penetrates the rain-cutting plate 2 vertically, and this ventilation opening 3 is A cylindrical stand-up piece 24 rising upward is provided, and the upper part of the rain cutter plate 2 is covered with a ridge tile 4 having a substantially inverted U-shaped cross section with a vertical interval apart.
A tile ventilation opening 5 is provided vertically and penetratingly at a different position from the tile ventilation opening 5.
Hanging piece 2 that prevents rainwater from scattering in the direction of
Drop the ridge tile 3 and place the ridge tile 4 at the appropriate place in the length direction of the ridge.
This relates to a roof ventilation structure in which the gap between the ridge tile and the rain-cutting plate 2 is filled with a blocker 7, and in this way, the gap between the ridge tile and the rain-cutting plate is closed at an appropriate position along the length of the ridge. By filling it with material, it was possible to create an ascending passageway and increase ventilation efficiency.

(Example) A roof board 12 as a roof base material 6 and an asphalt roofing 13 are laid over the entire roof on a tree 11 extending in the direction of the eaves, and a roof material 7 such as a flat tile is roofed on top of this. It has been set up. A ridge ventilation opening 1 communicating with the attic is formed at the top of the ridge. In the ridge part, a ridge beam 14 which is long in the ridge length direction is fixed with a nail with a seal 15. A rain cutting board 2 is constructed between both ridge beams 14, 14, the rain cutting board 2 is fixed to the ridge beam 14 with screws 16, and the rain cutting board 2 covers the ridge ventilation opening 1. 8 in the figure is a drainage board. A vent hole 3 is formed in the rain cutter plate 2 to pass through it vertically. This vent 3 is shifted in position from the ridge vent 1. Approximately inverted U-shaped support fittings 17 are attached to the ridge beam 14 with the screws 16 on the rain cutting board 2 at intervals in the ridge length direction. 4 is approximately an inverted U in cross section
It is a letter-shaped ridge tile, and as shown in FIG. 3, a connection recess 18 is formed at one end in the length direction, and a connection part 19 that enters the connection recess 18 is formed at the other end. There is. A tile ventilation opening 5 is formed in the ridge tile 4, and a perforated plate 20 is fitted into the tile ventilation opening 5 to prevent birds such as sparrows and mice from entering. Then, by attaching the perforated plate 20 fitted into the tile ventilation opening 5 to the support metal fitting 17 with bolts 21 and nuts 22, the ridge tile 4 is attached to the support metal fitting 1.
It is installed on 7. The tile ventilation opening 5 and the ventilation opening 3 are shifted in position in the ridge length direction, and the perforation plate 20
The rainwater that has passed through is prevented from directly entering the ventilation hole 3 of the rain cutting board 2. In addition, a hanging piece 23 in the form of a draining baffle plate is suspended from the perforated plate 20.
It is designed to prevent rainwater entering from 0 from being blown to the vent 3 side and scattering.

As shown in FIG. 3, a cylindrical rising piece 24 is inserted into the vent 3 of the rain cutting board 2, and the cylindrical rising piece 24 is fixed as a rising peripheral wall around the 4th circumference of the vent. be. A rubber gasket 25 is fitted into the upper part of the cylindrical upright piece 24, and the lower end surface of the rubber gasket 25 is pressed against the rain cutter plate 2 to maintain sealing performance. A water return collar 26 is provided outward from the upper peripheral edge of the cylindrical upright piece 24. The cylindrical upright piece 24 and the water return collar 26 are made of synthetic resin and are integrally formed. In this way, the rainwater passing through the perforated plate 20 is prevented from being blown into the vent 3 by the wind blown from the perforated plate 20 by the cylindrical rising piece 24 serving as the rising peripheral wall, and the rainwater is prevented from adhering to the rubber packing 25. The water return collar 26 can prevent rainwater from being blown up by the wind and entering the vent 4.

A long tunnel-shaped ventilation space 27 is formed between the rain cutter plate 2 and the ridge tile 4 having a tile ventilation opening 5 with a substantially inverted U-shaped cross section, and does not have a tile ventilation opening 5. Between the space 30 formed by the ridge tile 4' and the rain cutout board 2 and the ventilation space 27, the space 27 between the rain cutout board 2 and the ridge tile 4 is closed with obturators 9, 9.
It is filled in. By closing the tunnel-shaped void 27 that is long in the direction along the ridge in the length direction, a rising passageway leading to the ridge ventilation opening 1, the ventilation opening 3 of the rain cutting board 2, and the tile ventilation opening 5 of the ridge tile 4 is created. can be configured,
This allows for efficient ventilation.

The obturator 9 is made of foamed synthetic resin such as foamed polyethylene, and as shown in FIG. 5b, the obturator 9
Attach double-sided tape 10 to the bottom surface of
It is attached to the rain cutting board 2 through the 0. By making the obturator 9 made of foamed synthetic resin, the obturator 9 can be slightly deformed and can follow changes in the slope of the roof as shown in FIG.

FIG. 7 and FIG. 8 show other embodiments of the same as above,
A corrugated roofing material 7 is used instead of the flat roofing material 7, and when the corrugated roofing material 7 is used in this way, the roofing material 7 and the ridge 1
4, a corrugated plate-shaped gap is formed, but this gap is filled with a side door 29 made of resin foam. The door 29 is fixed by passing the needle 15 with a seal through the door 29.

[Effect of idea]

In summary, the present invention uses a blocker to fill in the gap between the ridge tile and the rain-cutting board at an appropriate location along the length of the ridge, so that the gap between the ridge tile with the tile ventilation opening and the rain-cutting board forms a tunnel. Therefore, the ridge ventilation hole, the rain cutter board ventilation hole, and the ridge tile ventilation hole can constitute a rising passage, and the rain cutter board ventilation hole and the ridge tile ventilation hole can be closed off at both ends. The ridge tiles are penetrated vertically by the tile ventilation openings, and the ventilation openings have cylindrical raised pieces that stand up upwards, allowing hot air from the attic rising from the ridge ventilation openings to pass through them vertically. In addition to this, the cylindrical upright piece of the vent can further promote upward flow, and the tile ventilation There is a hanging piece hanging from the opening that prevents rainwater from scattering in the direction of the rain-cutting board's vent, which prevents rainwater that has entered through the tile ventilation opening from blowing directly into the rain-cutting board's vent. It has the advantage of being possible.
