Description

[Detailed description of the invention] The present invention relates to a ridge structure for ventilation, and more specifically, ventilation opening members 3 are provided in the ridge part facing each other across a vertical ventilation passageway 2 communicating with the attic space 1, and the ridge part The ventilation opening member 3 is formed to have a cross-sectional shape that covers the upper surfaces of the ridge sills 11 and the caps 14 on both sides, and has an upright piece 26 erected upward from the edge of the ridge part of the ridge 11. A rain cover 4 is disposed above the vertical ventilation passageway 2 above the upper end, and a windbreak plate 5 covering the upper surface of the ridge 11 of the ventilation opening member 3 from above the rain cover 4 is attached to the ventilation opening on both sides. An exhaust port 18 is disposed above each member 3 and communicates with the vertical ventilation passageway 2 between the upper ends of the windbreak plates 5 on both sides.
In a ventilation ridge structure in which a rainwater drain 6 is formed between the lower edge and the upper surface of the ridge sill 11 of the ventilation port member 3, a vertical ventilation passage 7 is separated from the outside of the drain 6 to prevent wind. This relates to a ventilation ridge structure in which a drainage port windbreak plate 8 is provided approximately parallel to the plate 5, and vertical ventilation passages 7 are opened at the top and bottom to the outside.

In the conventional ventilation ridge structure, as shown in Fig. 1, a pair of ventilation opening members 3' are opposed to each other in the ridge part with a vertical ventilation passageway 2' communicating with the attic space 1' in between. A rain shade 4' is provided above the vertical ventilation passageway 2', and a windbreak plate 5' is provided to cover from above the rain shade 4' to the upper surface of the ridge of the exhaust port member 3'. A rainwater drainage port 6' is formed between the lower edge of the windbreak plate 5' and the ventilation port member 3'. By the way, since this drain port 6' opens laterally outward, rainwater blows from the drain port 6' in the direction of the solid line arrow during strong winds and rain, and enters the attic space 1' via the vertical ventilation passage 2'. The problem was that rainwater could seep in and cause leaks. The broken line arrow in Figure 1 indicates the drainage route of rainwater.

The present invention was developed in view of these conventional drawbacks, and its purpose is to provide a ventilation system that can prevent rainwater from blowing in during strong winds and rain without impairing the rainwater drainage function. It is located in providing a ridge structure.

Embodiments of the present invention will be described in detail below based on the drawings.

A is a ventilation ridge, which is intended to ventilate the attic space 1. Ventilation ridge A is connected to ridgepole 10 via rafter 9
It is installed so as to straddle the left and right ridgepoles 11 placed above. The configuration of ventilation building A will be explained below. Reference numeral 3 denotes a ventilation opening member, in which a substantially gate-shaped metal fitting 13 made of bent iron band is mounted on the upper surface, and the ridge sill 11 is mounted together with the metal fitting 13.
The cap 1 is attached to the ventilation opening member 3 and is attached to the top and outer surfaces of the ridgepole 11 and to the ridgepole 11.
4. The part of the tile 15 connected to the cap 14 is covered over the entire length in the ridge length direction to drain water around the ridge sill 11 and the cap 14. The ventilation opening member 3 is provided across the entire length of the ridge in the longitudinal direction of the ridge, apart from the vertical ventilation passage communicating with the attic space 1. A windbreak plate 5 is provided on the outside of each substantially gate-shaped metal fitting 13, and the upper end of the windbreak plate 5 is positioned above the rain-shedding shade 4, and the lower end of the windbreak plate 5 is positioned above the ridge of the ventilation opening member 3. It is located at the ridge 11 portion, and the lower edge of the windbreak plate 5 is fixed to the ridge 11 together with the ventilation hole member 3 with nails 16. The windbreak plate 5 prevents crosswinds from blowing into the ventilation building A. An exhaust port 18 is opened in the center of the top plate 17 that is connected to the upper edges of the left and right windbreak plates 5 over the entire length in the ridge length direction. In the embodiment, the upper edges of both windbreak plates 5 extend along the metal fittings 13, the extending edges are made to stand up, and the space between these upright pieces 19 serves as the exhaust port 18. The top of the metal fitting 13 is formed into an inclined surface 20 which rises toward the center, and the top plate 17 of the windbreak plate 5 along this inclined surface 20 also forms a rising surface which rises toward the tip. Approximately gate-shaped metal fitting 1
Support body 21 on which the rain hat 4 is mounted on the upper and lower middle part of 3
is provided. The support body 21 is formed by bending a band iron, and has an arch shape as a whole, and a receiving portion 22 that is convex downward is formed at the top of the arch shape.
The rain draining shade 4 has a rhombic cross-sectional shape, and is mounted and fixed on the receiving part of the support 21 by utilizing the rhombic shape, and is inclined in the vertical direction for the left and right rising exhaust passages below the exhaust port 18. Rain-driving hat 4 across the slope interval
are arranged. The rain-cutting hat 4 is made by joining a rain-cutting hat main body 23 having a chevron-shaped top surface with a back plate 24 having a chevron-shaped lower part on both sides thereof. Ame-kiri hat 4
Cut edges 25 are formed along the entire length on both side edges.

An upright piece 26 is provided on the inner side of the ventilation port member 3, and the upright piece 26 is inclined further inwardly and upwardly from the upper edge of the upright piece 26.
7 is formed. There is a ventilation hole 28 connected to the attic space 1 between the two end edges. However, a ventilation opening 2 that communicates with the attic space 1 is located below the rain cap 4.
8, and the opening 28a of the ventilation opening 28 is covered with a rain hat 4.
It is located below the side edge 4a of the rain-drying shade 4 and inside the rain-drying hat 4. According to such a configuration, the ventilation port 2
A second ascending route Y along the lower surface of the top plate 17 is formed from 8 to the first ascending route X along the lower surface of the diamond-shaped rain-draining shade 4, and is a rising exhaust passage that constantly ascends from the ventilation opening 28 to the exhaust opening 18. The hot air from the attic space 1 can be exhausted with little resistance through this ascending exhaust passage, and in addition, the cross wind that passes over the exhaust port 18 opened at the top of the ventilation ridge A can be sucked in. This action further enhances the excretion effect.

As shown in FIGS. 3 and 5, a drainage port 6 is formed on the lower edge of the windbreak plate 5 between the ventilation port member 3 and the rainwater that falls from the drainage port 6 flows in the direction of the chain arrow. The water flows down along the drainage passage of the drain hole 6.
Water is drained from the roof onto the roof.

A drain windbreak plate 8 is attached to the extension 13a from the metal fitting 13 on the outside of the drain 6 across the vertical ventilation passage 7 to prevent strong wind and rain from blowing into the drain 6 from the sides. be. The upper and lower parts of the vertical ventilation passage are open to the outside, so even if strong wind blows in from below along with rain, the strong wind will escape from above through the vertical ventilation passage 7, as shown in Figure 3. Wind and rain are prevented from blowing into the drain port 6.

In summary, the present invention separates the vertical ventilation duct from the outside of the drain and installs the drain outlet windbreak plate approximately parallel to the windbreak plate, and opens the top and bottom of the vertical ventilation duct to the outside.
Although it does not impair the drainage function of rainwater from the drain, it can prevent rainwater from blowing directly into the drain during strong winds and rain, even if rainwater blows in from above or below the vertical ventilation channel due to strong winds. Since the vertical ventilation ducts are open to the outside at the top and bottom, the rainwater that is blown in is discharged directly to the outside from above or below the vertical ventilation ducts along with the wind, which has the advantage of suppressing the blowing into the interior of the building from the drainage holes. be.
