Description

[Detailed Description of the Invention] The present invention relates to an attic ventilation system particularly for a roof having a ridge such as a gable, hipped roof, hipped roof, etc.

Conventionally, measures have been taken to ventilate the attic, such as providing a louver or ventilation hole in the side wall of the attic, or providing a ventilation hole on the lower surface of the eaves.

However, none of these methods were able to sufficiently ventilate the attic. In other words, the hot air and odors in the attic heated by strong sunlight,
Even though it stays just below the ridge, which is the top of the roof,
Conventional attic ventilation relies on air flowing in from the sides of the attic and air flowing into the lower part of the attic from the eaves, and the amount of air flowing in from these sources is extremely small unless there is a particularly strong wind. ,
It only serves to slightly dilute the heat and odor in the attic. Conventional ventilation methods can improve the problem to some extent by installing a large number of them over a wide area to increase the amount of air flowing into the attic, but this also has its limits when considering the flow of rainwater and the structure of the building. Particularly in the case of a hipped roof, the attic has a structure with almost no side walls, so it is extremely difficult to obtain sufficient ventilation of the attic using conventional ventilation means.

This invention solves these conventional drawbacks by perfecting ventilation in the attic, thereby preventing indoor temperature rise due to the accumulation of hot air and odors, dew condensation in the attic, and the occurrence of indoor odors. That is.

Hereinafter, the present invention will be explained in more detail with reference to the drawings.

FIGS. 1 and 2 are views showing one embodiment of the present invention. Along the roof ridge, on a barrel tree 1, two braces 2 are placed facing each other at an appropriate distance. ,
It is installed so that it protrudes above the roof.
Along the outer surface of the tree receiver 2, the upper end of the roofing material 3 is bent upward to form a rising portion 4, and on the outside thereof, there are legs of a rain gutter 5 that covers the upper surface of the tree receiver 2. Section 6 is covered.

The rain cutters 5 are a pair of left and right members that extend along the tree receiver 2, and their inner ends form a holding part 7 bent upward in an inverted U shape. Ryo Amagiri 5
The clamping parts 7 are facing each other, and there is an open circuit 8 between them.
It is becoming. Further, the outer end of the rain cutter 5 protrudes outward from the tree receiver 2 and is folded back downward to form an overhanging portion 9. The outer end of the rain cutter 5 extends downward from the base of the overhang portion 9 along the outer surface of the tree receiver 2. The leg portion 6 is formed by extending the leg portion and further protruding its tip portion obliquely downward toward the roof material 3. Rain cut 5
is fixed by nailing its top and side surfaces to the support 2. In particular, the illustrated case assumes that the roofing material 3 is made of iron plates, but the present invention is not limited to this, and of course can be applied to roofs made of other slate tiles, etc. The shape of the legs 6 can be changed according to the material, shape, etc. of the roofing material 3, and furthermore, caulking material can be used in combination to make the space between the wooden support 2 and the roofing material 3 waterproof.

Both rain gutters 5 are covered with covers 11 having a substantially inverted U-shape having ventilation holes 10 on the sides, and a ventilation passage 12 is formed between the rain gutters 5 and the cover 11. The ventilation passage 12 is communicated with the attic 13 through the space between the support trees 2 and the open passage 8. Preferably, at least one end of the ventilation passage 12 is opened to the outside through a louver (not shown) for preventing rainwater from blowing in, so that ventilation can be smoothly performed.

Both lower ends of the cover 11 are bent upward and inward in a U-shape to form side grooves 14. A drain hole 15 is formed in the lower part of the side gutter 14. The inner end of the side groove part 14 is bent outward in a U-shape to form a holding part 16, and furthermore, the end thereof is
A tongue piece 17 is formed by extending inward and bending the tip upward. Furthermore, a heat insulating and sound absorbing material 18 such as urethane foam is attached to the inner surface of the cover 11. This heat-insulating and sound-absorbing material 18 is for preventing dew condensation on the inner surface of the cover 11, and also for preventing the sound of rain, especially when the cover 11 is constructed of an iron plate or the like. And this cover 1
1 is attached by fitting the holding part 16 and the tongue piece 17 of the cover 11 into the projecting part 9 and the holding part 7 of the rain gutter 5, respectively.

Next, I will explain how to assemble this device.
First, the tree support 2 is fixed along the ridge of the roof.
Next, the rain cutter 5 is installed on the tree receiver 2, and its upper surface and side surfaces are nailed to the tree receiver 2 to fix it. The cover 11 is slid from the end of the fixed rain cover 5 to an appropriate position and positioned.

According to such a device of the present invention, the attic 13
The hot air and odor inside are guided by their natural upward force to the ventilation passage 12 through the space between the two supports 2 and the opening 8, and are discharged to the outside through the ventilation hole 10.
Therefore, hot air and odors do not accumulate in the attic 13, impairing livability or accelerating the aging of the building.

Furthermore, this device has excellent effects in terms of its own durability and waterproofness. That is, as described above, the cover 11 has its holding portion 16 and tongue piece 17.
It is fixed by fitting it into the overhanging part 9 and the holding part 7 of the rain cutter 5, and there is no need to use nailing for fixing, and there is no need to worry about corrosion or rain leakage from the nailed part. Not at all. Also,
Since the nailing part for fixing the rain gutter 5 is also covered by this cover 11, the nailing part is not exposed to the outside at all. In particular, when it is necessary to prevent the cover 11 from rattling during strong winds, adhesive may be applied to the contact surface between the cover 11 and the rain gutter 5, or the cover 11 may be installed with sufficient spacing between the roofing materials 3. Alternatively, a band having a cross-sectional shape similar to the outer shape of the cover 11 may be attached from above, and the lower end of the band may be nailed to the support 2 below the cover 11.

Furthermore, in this device, even if rainwater should blow in through the ventilation hole 10, there is almost no possibility that it will infiltrate into the attic 13. That is, if the ventilation hole 10
Even if rainwater blows in from the opening, it will be blocked by the tongue pieces 17 and the clamping parts 7 located on both sides of the open channel 8,
It is washed away along the slope of the lower surface of the cover 11 in the direction of the side groove portion 14. The rainwater that has entered the side gutter 14 is then discharged onto the roofing material 3 through the drain hole 15. In order to more reliably exhibit such an effect, it is preferable to form the ventilation hole 10 below the side surface of the cover 11 as close to the side gutter 14 as possible. In addition, in order to ensure drainage, the bottom of the side gutter 14 is sloped outward.
It is preferable to form a drain hole 15 at the lowest part.

The rain drain 5 also serves to restrict the open circuit 8 and prevent the hot air and odor from the attic 13 that have once entered the ventilation passage 12 from flowing back, especially as shown by the dotted line in FIG. Attach the lid 19 and open the circuit 8
It is also possible to limit the opening position. This lid body 1
9 is preferable from the viewpoint of preventing rainwater from entering the attic 13, and especially in the vicinity of the ventilation hole 10, it is preferable to close the opening 8 with the lid 19.

The rain gutter 5 and cover 11 in the present invention are usually made of metal plates such as iron, copper, aluminum, etc., but they may also be made of synthetic resin. Further, the shape of the cover 11 is not limited to that shown in the drawings, but may include a semicylindrical shape, a shogi piece shape, etc.
Not only can it be freely selected according to the appearance of the roof, but the ridge can be made to have a sense of weight and the appearance of the roof can be further improved.

As explained above, the present invention not only provides complete attic ventilation, extends the life of the house and improves its livability, but also does not impair the exterior appearance at all.
