The crown roof tile R ₂ is attached to the sleepers 3 by nailing or fixing the roof tiles together with plaster or the like.
[0027]
Thus, since the apparatus main body 1 that can be installed using the stopper 2 as a base is provided, it can be reliably installed with a simple structure on a sloped roof of a house that is not laid with a roof tile as a ventilation device for a house building. .
[0028]
In the house building ventilation device, as shown in FIG. 10, outdoor air is taken from the outdoor side ventilation hole 15, flows through the ventilation interval 14 from the indoor side ventilation hole 16, and flows into the ventilation hole of the building part. Since indoor air is discharged from the vent 15 on the outdoor side via the route, indoor and outdoor air can be ventilated.
[0029]
When the outdoor air is taken in, the wind with rainwater is formed so that the outdoor-side vent 15 is narrower than the ventilation gap 14 even from the upper side toward the vent 15 on the outdoor side. Less wind intrusion. About the wind which goes upwards from the downward direction of a sloped roof, since it can be swung up by the front board part 11b which exhibits an upward slope toward the upper end side of the standing wall board part 11a, it can prevent flowing into the vent 15 on the outdoor side.
[0030]
Even if the wind with rainwater enters the ventilation interval 14 from the vent 15 on the outdoor side, it flows while meandering on the baffle plates 12b, 12c, 13b, 13c, so that the rainwater is drained. Even if rainwater is not completely drained by the baffle plates 12b, 12c, 13b, and 13c, it is blocked by the inner enclosure frame 4, and therefore does not reach the ventilation opening of the ridge. Therefore, it is possible to reliably prevent rainwater from entering the ventilation opening of the ridge together with the outside air.
[0031]
The above-described embodiment has been described based on the case of laying included construction of roof tile R ₁ waveform, the flat slate plates and the like can also be applied to the insole included construction as roof tiles. When this flat plate is used as a roof tile, the stopper 2 and the inner enclosure frame 4 having a relatively low rising height can be assembled. Moreover, although it demonstrated based on the slope roof of the house which does not lay a roof tile, it is applicable similarly to the slope roof of the house where a roof tile is laid.
[0032]
【The invention's effect】
As described above, according to the ventilation device for a house building part according to claim 1 of the present application, one sleeper is spanned and fixed to the bridge plate part of the fastener, and the leg plate part of the fastener is interposed between the bottom plates. By attaching the top of the top plate to sleepers and fixing it to the indoor side vents, and by installing a device body that can be installed with a stopper as a base, it is easy even for sloped roofs of houses that do not lay roof tiles The structure can be installed reliably.
[0033]
At the same time, each stopper piece portion of the spacer plate is hooked on the opening edge of the standing wall plate portion, and the standing plate portion of the spacer plate is positioned closer to the lower end plate surface of the top plate and the plate surface of the bottom plate than the opening of the standing wall plate portion. The top plate close to the bottom plate is fixed to the spacer plate plate, and a predetermined gap maintained between the top plate and the bottom wall plate is used as the vent on the outdoor side. Since the gap is held by the spacer plate, it is possible to reliably install the apparatus main body with a simple structure by holding the outdoor-side vent hole with the spacer plate.
[0034]
According to the ventilation device for a house building part according to claim 2 of the present application, a predetermined interval to be maintained between the ceiling plate part of the top plate and the standing wall plate part of the bottom plate is a ventilation interval between the top plate and the bottom plate. Since the spacer plate keeps the gap between the spacer plate and the outdoor side vent, which is narrower and lower than the standing wall plate part of the bottom plate, even if wind with rainwater moves from above to the outdoor side vent, The air vents on the outdoor side, which are narrower than the air gap, are suppressed to a small extent, and the wind directed upward from the lower side of the sloped roof can be swung upward at the front plate portion, so that it can be prevented from flowing into the air vents on the outdoor side.
