DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ventilation ridge structure that can naturally ventilate an attic space in a ridge section that is the top of a house, and more specifically, the present invention relates to a ventilation ridge structure that can naturally ventilate an attic space in a ridge section that is the top of a house. It is a ridge structure for ventilation having an exhaust port 3 that opens to the outdoors, and there are draining plates 1 on the left and right ridge base materials 9a, which are substantially parallel to the ridge, over the entire length of the ridge.
0 and 10 are laid, the opening 5 is opened vertically between the upper edges of both draining boards 10 and 10, and windbreak plates 1 and 1 are installed in the middle part of the width of the draining board 10 from the ridge toward the eaves. The above-mentioned exhaust ports 3 are installed vertically and open vertically in the top plate 2 extending between the upper edges of both windbreak plates 1, 1.
An upright piece 17 extending upwardly is provided vertically on the upper edge of the right drain plate 10, and an inclined piece 19 is connected diagonally upwardly from the upper edge of the upright piece 17 toward the outer right side. An extending piece 18 extending upward is vertically provided on the upper edge of the inclined piece 19, and the right half of the rain hat extends outward to the left and diagonally upward from the upper edge of the extending piece 18. 4a is formed below the exhaust port 3, and the left drain plate 10
An upright piece 17 extending upward is provided vertically on the upper edge of the upright piece 17, and an inclined piece 19 extending diagonally upward is provided from the upper edge of the upright piece 17 toward the left outside. The left half of the rain hat 4b is formed to face outward to the right and slope diagonally upward. This relates to a ventilation ridge structure characterized in that a drain opening 24 is provided between the edge and the drain plate 10.

In the conventional ventilation ridge structure, as shown in Fig. 1, the exhaust port 3' facing the outdoors and the opening 5' leading to the attic space are formed in the form of a glazed door toward the side to prevent wind and rain. The purpose was to provide ventilation while suppressing the blow-in of air. In addition, as shown in FIG. 2, another conventional example has a configuration in which the opening 5'' and the inner opening 5 connected thereto are oriented in the vertical direction instead of the louver door.However, in both of these, the exhaust port 3 Because the exhaust port 3' was facing laterally, it was easily exposed to the wind, and when exposed to the wind, the exhaust effect was significantly reduced.
There was a drawback that a backflow phenomenon occurred in some cases. Furthermore, since all of the conventional systems discharge hot air laterally, there is a large resistance to discharging the rising hot air laterally, and the hot air stagnates inside the ridge, which tends to cause temperature rise. It was hot.

The present invention has been made in view of these conventional drawbacks, and its purpose is to always maintain an exhaust passage from the opening connected to the attic space to the exhaust outlet facing outdoors through a rational configuration. By setting it on an upward path, the hot air exhaust effect can be greatly increased, while suppressing wind blowing in. On the other hand, crosswinds can increase the exhaust effect, and suppressing wind blowing from both sides. By doing so, the purpose is to provide a ventilation ridge structure that can prevent the drainage of rainwater from being obstructed by crosswinds, and has good drainage and drainage.

Embodiments of the present invention will be described in detail below with reference to the drawings.

A is a ventilation ridge, which aims to ventilate the attic space B. Ventilation ridge A connects to ridgepole 8 via rafter 7
It is attached so as to straddle the ridge beams 9, 9, which serve as left and right ridge base materials 9a placed above. Below ventilation building A
The configuration of is explained. Reference numeral 10 denotes a drain plate, which is attached to the ridge sill 9 by a substantially gate-shaped metal fitting 11 made of bent iron band, and the drain plate 10 covers the top surface and outer surface of the ridge sill 9,
The ridge base material 9a, which is made up of a Kasagi 12 attached to the ridge sill 9 and a tile 13 portion connected to the Kasagi 12, is covered over the entire length in the ridge length direction to drain water around the ridge base material 9a. . A windbreak plate 1 is provided along the outside of each substantially gate-shaped metal fitting 11, and the lower edge of the windbreak plate 1 is fixed to the ridge sill 9 with a nail 14 together with a drainage plate 10. The windbreak plate 1 prevents crosswinds from blowing into the ventilation building A. An exhaust port 3 is opened in the center of a top plate 2 that connects the upper edges of the left and right windbreak plates 1, 1 over the entire length in the ridge length direction. In the embodiment, the upper edges of both windbreak plates 1 extend along the metal fittings 11, the extending edges are made to stand up, and the space between these upright pieces 15 serves as the exhaust port 3.
The top of the metal fitting 11 is an inclined surface 1 that rises toward the center.
6, and the extending portion of the windbreak plate 1 along this inclined surface 16 also becomes a rising surface that rises toward the tip.
In FIG. 4, the inner side of the right draining plate 10 stands upward, and the upper edge of this standing piece 17 is bent diagonally upward in the direction of the right windbreak plate 1 to form an inclined piece 19. The upper edge of the inclined piece 19 is raised along the windbreak plate 1 to form an extending piece 18. Thereafter, the right half 4a of the rain hat is formed below the exhaust port 3 by tilting upward to the left from the upper edge of the extending piece 18. Standing piece 17 of left water section 10
A sloping piece 19 that slopes diagonally upward from the upper edge to the right is formed, and the left half of the rain hat 4b that slopes upward from the upper edge of this sloping piece 19 to the right is the right half of the rain hat. It is formed below 4a. In this way, the left half of the rain hat 4b and the right half of the rain hat 4a are combined to form the rain hat 4.
has been configured. A water return 20 is formed at the tip of the left half 4b of the rain hat and the right half 4a of the rain hat, respectively. According to such a configuration, the left and right draining plates 1
An opening 5 between the upright pieces 17 and 17 of Nos. 0 and 10 communicates with the attic space B, and from this opening 5 the rain flows along the first ascending path X along the lower surface of the left half of the rain hat 4b. A second ascending route Y is formed along the lower surface of the right half of the cut hat 4a, and a rising exhaust passage that always ascends from the opening 5 to the exhaust port 3 is formed, and air is discharged from the attic space B through this ascending exhaust passage. Hot air can be exhausted with little resistance, and in addition, the suction effect of the cross wind that passes over the exhaust port 3 opened at the top of the ventilation ridge A further enhances the exhaust effect.

As shown in FIGS. 4 and 6, a water cutout 24 is formed at the lower edge of the windbreak plate 1, and rainwater falling from the exhaust port 3 flows down along the drainage passage 6 in the direction of the chain arrow. This water is then drained onto the roof through a water outlet 24.

In summary, the present invention involves laying drain plates over the entire length in the ridge length direction on the left and right ridge base materials that are substantially parallel to the ridge, and creating an opening that opens in the vertical direction between the upper edges of both drain plates. , a windbreak board is erected in the middle of the width direction from the ridge to the eaves of the drainboard, and an exhaust port that opens vertically is opened in the top board that spans between the upper edges of both windbreak boards, The upper edge of the board extends upward and to the left to form the right half of the rain-draining hat below the exhaust port, and the upper edge of the left draining board extends upward and to the right to form the rain-drying hat. Since the rain hat half is formed below the right half,
The exhaust path from the opening leading to the attic space to the exhaust port leading outdoors can be set to a rising path that constantly rises at any point, eliminating the possibility of accumulating hot air and exhausting the air with little resistance. It has the advantage of being able to improve the discharge effect. Furthermore, since the exhaust port is located on the top plate and windbreak plates are provided on both sides, wind and rain can be prevented from blowing in from the sides, and the suction effect of crosswinds passing above the exhaust port can further improve exhaust efficiency. There are advantages that can be achieved. Moreover, since wind can be prevented from blowing in from the side, there is no obstruction to the drainage of rainwater that has entered the interior, and there is an advantage in that drainage and drainage of rainwater can be improved. In addition, the right draining board and the right half of the rain hat are formed in series, and the left draining board and the left half of the rain hat are formed in a series, so the left and right halves of the rain hat are formed in series. This has the advantage that the rainwater that has flowed down on the body can be discharged without causing any leakage, and the rainwater can be cleared even better.
In addition, an extending piece is hung from the lower end of the right half of the rain hat, and the lower end is approximately U-shaped, so the left half of the rain hat can be placed below the right half of the rain hat. Even if the right half of the rain hat and the left half of the rain hat are stacked vertically, the extension piece maintains a constant distance between the upper and lower halves of the rain hat, maintaining the ventilation flow path and increasing the slope. By forming the lower end into a roughly U-shape, the half of the rain canopy can be made longer, preventing rainwater from flowing back into the attic space, and ensuring that rainwater flows into the attic space. Infiltration can be prevented. In other words, overall, by greatly increasing exhaust efficiency, eliminating the accumulation of hot air, and preventing strong winds from blowing in from the side, effective ventilation of the attic space can be achieved, reducing hot air exhaust in the summer and reducing heat exhaustion in the winter. It has also been possible to effectively prevent condensation, extending the lifespan of houses.
