Description

[Detailed explanation of the idea] This invention relates to a ridge ventilation system.

Conventionally, ventilation holes were formed in the part corresponding to the eave of a ventilation accessory in the shape of a house (Utility Model Publication No. 137616/1983),
An integrally formed draining plate (Special Publication 50-7850)
No.) was hot. However, these conventional examples have the disadvantage that rainwater that enters through the ventilation holes is not drained sufficiently.

Therefore, the purpose of this invention is to provide a ridge ventilation system that can reliably prevent rainwater from entering.

A first embodiment of this invention is shown in FIGS. 1 to 3. In other words, this ridge ventilation system has ventilation openings 10
Standing parts 1 installed on both sides of the ridge of the roof 11
Drainage plates 16 and 16' having the shapes 7 and 17', a roof equivalent part 2, an eaves equivalent part 3, an eave equivalent part 4, and a corrugated wall equivalent part 5 are integrally formed into a house shape using a thin plate 1. The wall equivalent portion 5 is connected to the draining plate 16,1.
6', and a ventilation hole 7 formed in the part 4 corresponding to the eaves of the ventilation accessory 6.
and a water return 8 extending from the upper end of the draining plates 16, 16' and facing the inside of the ventilation hole 7. In this case, the thin plate 1 is a stainless steel plate,
It is corrosion resistant because it uses a PVC steel plate with a vinyl chloride coating applied to an aluminum plate, copper plate, or colored iron plate. Further, the roof equivalent part 2, eaves equivalent part 3, soffit equivalent part 4, and wall equivalent part 5 are formed by bending a single thin plate 1, but each is connected using screws or rivets. Good too. The ventilation accessory 6 formed by this thin plate 1 is a hollow tree 1 of the roof 11.
It is connected and held by reinforcing metal fittings 13 to the roofing board 9 placed on the roof tiles 14, and the receiving beam 15 is installed on the roof tile 14.
A deformed angle-shaped draining plate 16,1 is placed on 15'.
6' is installed upright, and the wall-corresponding part 5 of the ventilation accessory 6 is fitted onto the outer surface of the raised parts 17, 17'. At this time, the ends of the raised parts 17, 17' of the draining plates 16, 16' are bent so as to face the inside of the part 4 corresponding to the eaves of the ventilation accessory 6, as shown in FIGS. 2a and 2b. It forms a water return 8 for the ventilation hole 7.
19 is a caulking material, and 20 is a waterproof sheet.
As a result, for ventilation, the inside of the attic or the roof panel 18 is communicated with the inside of the ventilation accessory 6 through the ventilation hole 10, and the inside of the ventilation accessory 6 is communicated with the inside of the ventilation accessory 6 through the ventilation hole 7.
The inside of the ventilator 6 communicates with the outside of the ventilation accessory 6 to provide natural ventilation as shown by the arrow, which prevents temperature rise due to radiant heat in the summer, helps prevent condensation in the winter, and also prevents moisture from leaking in snowy areas. It will be helpful. Furthermore, the wall equivalent part 5 has a water return wave surface 2 due to its waveform.
1 is formed, which prevents rainwater from rising along the surface of the wall equivalent part 5 of the ventilation accessory 6 and entering the ventilation hole 7 due to wind and rain, and also prevents rainwater from entering the ventilation hole 7 directly. The water return 8 prevents intrusion into the inside of the ventilation accessory 6, and the rainwater blocked by the water return 8 flows down between the raised parts 17, 17' of the draining plates 16, 16' and the wall equivalent part 5. The water flows down onto the roof tiles 14. Figure 3 shows ventilation accessory 6
A cap 22 is shown that closes both ends of the cap.
This cap 22 is made of a PVC steel plate, and an inner ear 23 is formed on the inside to have the cross-sectional shape of the ventilation accessory 6. The cap 22 is airtightly covered with caulking via a complete band and connected with rivets to prevent rain. It is made complete and plays the role of an onigawara.

A second embodiment of this invention is shown in FIG. That is, in this ridge ventilation system, the water return 8 is arranged so as to block the ventilation hole 7 inside the soffit equivalent part 4, and the ventilation hole 7 is arranged in a staggered manner with respect to the ventilation hole 7 as shown in FIG. 4b. 24 was formed. In this case as well, it is possible to prevent rainwater from entering as well as ventilation. The other parts are the same as the first embodiment,
It has the same effect.

As described above, the ridge ventilation system of this invention consists of a draining plate having raised parts installed on both sides of the ridge of the roof where the ventilation opening is located, a part corresponding to the roof, a part corresponding to the eaves, a part corresponding to the soffit, and a corrugated part. A ventilation accessory in which a wall-equivalent part is integrally formed into a house shape with a thin plate and the wall-equivalent part is fitted onto the outer surface of the draining board, and a ventilation part formed in the eave-equivalent part of the ventilation accessory. Since it includes a hole and a water return that extends from the upper end of the draining plate and faces the inside of the ventilation hole, the following effects are achieved.

In other words, since the wall-corresponding part is formed in a corrugated shape, it is possible to suppress rainwater from rising along the wall-corresponding part, and even if rainwater enters the ventilation hole, there is a water return on the back side of the ventilation hole, so the rainwater can be prevented from flowing back up. The water can then flow down along the drainage board on the back side of the wall-equivalent part. In addition, rainwater adhering to the inner surface of the eaves-corresponding part of the ventilation facility can be allowed to flow down from the water return to the back side of the wall-corresponding part along the draining plate, which has a better draining effect compared to conventional examples. become certain. Furthermore, even if rainwater enters between the wall-corresponding part and the draining board, the gap is small, so it will not rise from the lower end of the draining board to the water return, and therefore there is no need for a watertight structure, simplifying the structure.
