The draining board (2) has an upright portion (7) facing the upright portion (3) of the ventilation ridge plate (1), and an inclined portion ( 8) Roof (11)
It is arranged and arranged above. As a result, in the one-sided roof ridge part, the spar (4) provided in the inclined part (5) of the ventilation ridge plate (1), the vent (6) formed in the upright part (7) of the draining board (2), And the open field opening (10) communicates, and natural ventilation of the back of the hut in the one-way roof is enabled.

Further, since the draining board (2) is located immediately below the ventilation building board (1), it is concealed by the ventilation building board (1),
It is not exposed, and the ventilation ridge plate (1) can have the same appearance as the ridge members provided in the single-flow roof ridge, and does not impair the aesthetic appearance of the single-flow roof.

Moreover, the rainwater flows on the roof tile (11) along the surface of the slope (5) of the ventilation ridge plate (1). In the unlikely event that the ventilation ridge plate (1) is installed on the slope (5),
Even if rainwater infiltrates, the draining board (2) can receive the infiltrated rainwater and flow it to the roof tile (11). That is, since the draining board (2) is provided with the upright portion (7), the rising water (7) prevents rainwater going to the open field opening (10), and the surface of the inclined portion (8) faces downward. Shed. Since the slope (8) is arranged on the roof (11), rainwater flowing down the surface of the slope (8) is discharged to the roof (11). Therefore, there is no risk of rainwater entering the back of the hut.

As described above, the ventilation structure of the single-flow roof of the invention of the present application can naturally ventilate the back of the hut without impairing the aesthetics of the single-flow roof, and can prevent rainwater from entering the back of the hut. is there.

In the ventilation structure with a single-flow roof according to the invention of this application, both the ventilation ridge plate (1) and the draining plate (2) can be formed from a single metal plate. Specifically, it can be formed by cutting, punching, bending, or the like. Further, the ventilation ridge plate (1) and the draining plate (2) can be joined in advance in order to facilitate construction. For example, as shown in FIG.
