DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation device.

[0002]

2. Description of the Related Art Conventionally, in order to ventilate a room, a ventilation device 50 as shown in FIG. In this case, the pedestal 52 of the ventilation device 50 is placed on the roof base material 53 as shown in FIG.
A water retaining material (waterproof sheet) 54 is laid on the roof base material 53 in order to receive the water that has entered the inside. The lower edge portion of the water retaining material 54 is raised along the inner surface of the front plate 52a of the gantry 52 provided in parallel with the ridge, stores the moisture A that has entered the inside, and convects the internal heat and air. It is evaporated to dryness.

[0003]

In the conventional ventilation device, since the moisture A is stored inside by the water retaining material 54 as described above, there is a problem that the moisture A may enter indoors when scattered in a strong wind. there were. Therefore, an object of the present invention is to provide a ventilator capable of draining the water contained therein.

[0004]

The ventilation device of the present invention comprises:
A ventilation device configured such that a cylindrical frame is placed on a sloping roof base material, a waterproof sheet is laid on the roof base material inside the base, and the interior and exterior communicate with each other to enable ventilation. , A gap is provided between the lower edge of the front plate of the gantry provided in parallel to the ridge and the roof base material, and the waterproof sheet is extended to the outside of the gantry through this gap, and the waterproof sheet is extended. It is characterized in that the end portion is superposed on a waterproof paper which covers the roof base material.

[0005]

According to the structure of the present invention, the moisture that has entered inside flows down along the waterproof sheet laid on the roof base material, and the lower edge of the front plate of the gantry and the roof base material provided in parallel with the ridge. The water is drained to the outside along the waterproof sheet that extends to the outside of the gantry from the gap between and. Further, since the extending end portion of the waterproof sheet overlaid on the building paper covering the roof bed material, the gantry
As well as improving the rain around, the moisture flows from the waterproof sheet along the waterproof paper and can escape to the roof surface.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A ventilation device according to an embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 2, this ventilation device 1 is provided so as to project on a roof ridge composed of a roof panel 10, and an opening 12 provided in the ridge can communicate with the inside and outside of the building for ventilation. As shown in FIGS. 4 to 6, the pedestal 2 of the ventilation device 1 includes a front plate 3 made of plywood, a rear plate 4, both side plates 5 and 5, and reinforcing members 6 arranged at the corners.
It is assembled into a square tubular shape with and. The lower edge of the side plate 5 has a chevron shape, and as shown in FIG. 2, it is provided along the roof base materials 11, 11 of the roof panels 10, 10 which are inclined on both sides of the ridge. Along with this, the front plate 3 and the rear plate 4 are arranged in parallel with the ridge and are supported by the side plates 5 and 5 as described later.

A mounting portion 13 having an opening in the front plate 3 and the rear plate 4 of the gantry 2 is provided and a ventilation box 14 is mounted. As shown in FIG. 7, the ventilation box 14 is a tubular member having openings 15 at both ends, and a projection 16 communicating with the opening 15 is provided on the upper surface. In the mounted state, the opening 15 of the ventilation box 14 is attached to the mounting portion 1 of the gantry 2.
It is attached by fitting so that it does not come out from 3. A top plate 17 is attached to the upper surface of the gantry 2. At this time, the inner surface of the top plate 17 is arranged at a distance from the protrusion 16 so that the protrusion 16 can be ventilated.

As shown in FIGS. 1 and 3, both sides of the front plate 3 are positioned so that the lower edge of the front plate 3 is located above the lower end of the side edge of the side plate 5 adjacent to the front plate 3. Support the plates 5 and 5 and form a gap 9 between the lower edge of the front plate 3 and the roof base material 11.
Is provided. In this case, the size B of the gap 9 is about 5 mm. The rear plate 4 has the same configuration, and the description thereof will be omitted.
On the other hand, the waterproof sheet 7 is laid on the roof base material 11 inside the pedestal 2, and the waterproof sheet 7 is placed through the gap 9 from the pedestal 2
Extend to the outside of. The extended end portion of the waterproof sheet 7 is placed on the waterproof paper 8 that covers the entire surface of the roof substrate 11 except the ventilation device 1. A roof tile 20 is laid on the waterproof paper 8. Further, a pressing girder 21 is attached to the lower end of the outer peripheral surface of the gantry 2 together with the base material 22 to press the roof tile 20 close to the gantry 2.
In addition, in FIG. 1, the pressing girder 21, the base material 22, and the roof tile 2
The illustration of 0 is omitted.

In the ventilator 1 constructed as described above,
Indoor air enters the inside of the ventilation device 1 through the opening 12 provided in the ridge, and wraps around from the side of the ventilation box 14 to project the projection 1.
6 is exhausted to the outside through the opening 15. Ventilation device 1
The air inside the box enters the ventilation box 14 due to the flow of air through the openings 15 at both ends.
This is because the inside of is under negative pressure.

To explain the operation of this embodiment, as shown in FIG. 3, the moisture A that has entered the inside of the ventilation device 1 flows down along the waterproof sheet 7, and the front plate 3 of the pedestal 2 is removed.
The water is drained to the outside along the waterproof sheet 7 extending to the outside of the gantry 2 through the gap 9 between the lower edge of the roof and the roof base material 11.
After this, water flows from the waterproof sheet 7 along the waterproof paper 8 and can escape to the roof surface. In this case, the water is drained from the flow gutter along with the water that has entered from between the roof tiles 20.

In this embodiment, as described above, the ventilation device 1
Since the water A that has entered the inside can be reliably drained to the outside,
Water is not accumulated inside the ventilation device 1, and water does not enter indoors even in the case of strong wind. Further, FIG. 8 shows another embodiment, in which unevenness is formed on the lower edge of the front plate 3'of the mount 2'and a gap 9'is provided. The gap can be formed in a corrugated shape or a gate shape.

Although the ventilation device 1 is provided at the ridge position in the above embodiment, it may be provided at a position displaced from the ridge. Also, although the outer plate of the ventilation device 1 is composed of the pedestal 2,
The outside plate of the ventilation device 1 may be separately configured and attached to a pedestal having a reduced height.

[0013]

According to the ventilation device of the present invention , the
Lay a tarpaulin on the roof base material of the section
A gap is provided between the lower edge of the
Since the waterproof sheet extends outside the pedestal, it is not
Internal to enter the water flows down along the waterproof sheets, gap
It can be drained from the space to the outside. Also, since the extended end of the waterproof sheet is stacked on the waterproof paper that covers the roof substrate, the rain around the pedestal will be good, and moisture will flow from the waterproof sheet along the waterproof paper. Can escape to the face. For this reason, the water that has entered the ventilation device can be reliably drained to the outside, so that water does not accumulate inside the ventilation device and does not enter the indoor space even during strong winds.
