SUMMARY OF THE INVENTION The present invention has been made to achieve the above object, and a roof ventilating apparatus according to claim 1 has an opening in a base plate having a waterproof sheet laid on an upper surface thereof. A cylindrical body that can be installed so as to protrude outward from the opening, and a lid attached to the upper part of the cylindrical body, wherein the lid has a flow of air communicating with the opening. An outlet is provided, and the baffle is provided with a baffle plate and a rainwater discharge port capable of discharging rainwater that has entered from the air outlet into the opening without dropping into the opening.

The roof ventilator according to the second aspect is characterized in that a drain is attached to the outer peripheral surface of the cylindrical body.

According to a third aspect of the present invention, in the roof ventilator, an eaves projecting outward from an outer peripheral surface of the cylindrical body is provided at the rainwater discharge port. is there.

(Function) The roof ventilation device according to the first aspect of the present invention can be installed at any position on the roof because the cylindrical body can be installed in the opening of the field board, and the cylindrical body has air. The baffle plate and the rainwater discharge port are provided so that the rainwater that has entered from the outlet of the cylinder can be discharged to the outside of the cylindrical body without dropping into the opening. Things.

According to the second aspect of the present invention, since the drain is attached to the outer peripheral surface of the cylindrical body, it is difficult for rainwater to enter through the gap between the cylindrical body and the base plate, and the waterproofness is further improved. Things.

According to the third aspect of the present invention, the roof ventilator is provided with an eave protruding outward from the outer peripheral surface of the cylindrical body at the rainwater discharge port. Rainwater can be prevented from entering, making it highly waterproof.

FIG. 2B is a cross-sectional view taken along the line AA of FIG. 1A, and FIG. 2 is a cross-sectional view showing a use state of the roof ventilation device of FIG.
1 and 2, 1 is a roof ventilation system, 11 is a cylinder, 12 is a mounting plate, 13 is a lid, 14 is an air outlet,
16 is a baffle plate, 19 is a rainwater outlet, 2 is a drainer, 3 is an eave, 4 is a waterproof sheet, 5 is a ground board, 6 is an opening, 7 is a roofing material, B is an air passage, C is a rainwater passage, It is.

The roof ventilation device 1 according to the present invention is made of a painted steel plate, and as shown in FIG.
And a lid 13 integrally attached to the upper part of the cylindrical body 11. The roof ventilation device 1 has an opening 6 in a field board 5 on which a waterproof sheet 4 is laid on an upper surface by projecting mounting plates 12 on both side edges of a lower end of a cylindrical body 11.
It can be installed so as to protrude outward.

The lid 13 is provided with two air outlets 14 and 14 communicating with the opening 6 of the base plate 5, and the cylindrical body 11 is provided with an opening for rainwater entering from the air outlet 14. A baffle plate 16 and a rainwater discharge port 19 that can be discharged to the outside without dropping to 6 are provided. One end of the baffle plate 16 is fixed to the inner peripheral surface of the cylindrical body 11, and the other end is bent upward to form a bent piece 17.
A gap is formed with the inner peripheral surface of the first member. In addition, an auxiliary baffle plate 18 is provided at a position adjacent to the bent piece 17 from the inside of the lid 13 toward the lower side.

A drainer 2 is attached to the roof ventilation device 1 on the outer peripheral surface of the cylindrical body 11. This drainer 2
Is formed by bending the upper end of an L-shaped plate-shaped mounting piece 21 obliquely downward, and is removably mounted to the cylindrical body 11 with screws, and inserts the waterproof sheet 4 between the mounting piece 21 and the mounting plate 12. A gap that can be formed is formed.

Furthermore, in the roof ventilation device 1,
Immediately above the rainwater discharge port 19, an eave 3 protruding outward from the outer peripheral surface of the cylindrical body is provided, and the eave 3 has a hanging piece 31 hanging downward.

Next, a method of using the above-described roof ventilation device 1 and the operation of the embodiment will be described with reference to FIG. First, the rainwater discharge port 19 is installed downward in the opening 6 of the inclined base plate 5, and the mounting plate 12 of the cylindrical body 11 is attached to the base plate 5 by nailing. Then, the waterproof sheet 4 is laid on the upper surface of the field board 5. At this time, the waterproof sheet 4 is laid on the mounting plate 12 around the opening 6. Then
The drainer 2 is fixed and attached to the outer periphery of the cylindrical body with screws, and finally the roofing material 7 is laid on the base plate 5 to complete the roofing work.

According to the roof ventilation device 1 installed as described above, the indoor air rising from the opening 6 is denoted by the reference character B.
The air is discharged from the outlet 14 to the outside through the air passage indicated by the symbol and is ventilated.

At this time, the roof ventilation device 1 of the present embodiment
Since the cylindrical body 11 can be installed in the opening 6 of the base plate 5, it can be mounted at any position on the roof. In addition, rainwater that has entered the cylindrical body 11 from the air outlet 14 can be introduced into the opening 6. Since the baffle plate 16 and the rainwater discharge port 19 that can be discharged to the outside of the cylindrical body 11 without being dropped are provided, the rainwater is discharged through a rainwater passage indicated by reference character C, and the rainwater enters. It is possible to achieve a waterproof property that is difficult to perform.

Further, in the ventilator 1 for a roof according to the present embodiment, since the drainer 2 is attached to the outer peripheral surface of the cylindrical body 11,
Rainwater hardly penetrates through the gap between the cylindrical body 11 and the base plate 5, and the waterproofness can be further improved.

Furthermore, the roof ventilation system 1 of the present embodiment.
Is provided with the eaves 3 protruding outward from the outer peripheral surface of the cylindrical body 11 at the rainwater discharge port 19, so that rainwater can be prevented from entering from the rainwater discharge port even if it receives a cross wind, and the waterproof property is improved. It will be excellent.

[0021]

According to the first aspect of the present invention, since the cylindrical body can be installed at the opening of the field board, it can be installed at any position on the roof. Accordingly, when the roof ventilation device is mounted on the attic storage or on the loft, ventilation of the attic becomes smooth, and the attic or loft can be used comfortably. Moreover, since the cylindrical body is provided with a baffle plate and a rainwater discharge port capable of discharging rainwater from the air outlet to the outside without dropping into the opening, rainwater enters the cylindrical body. It is possible to achieve a waterproof property that is difficult to perform.

According to the second aspect of the present invention, since the drain is attached to the outer peripheral surface of the cylindrical body, it is difficult for rainwater to enter through the gap between the cylindrical body and the base plate, and the waterproofness is further improved. Things.

According to the third aspect of the present invention, the roof ventilator is provided with an eave protruding outward from the outer peripheral surface of the cylindrical body at the rainwater discharge port. Rainwater can be prevented from entering, making it highly waterproof.
