Conventionally, various forms have been proposed as a building ventilation device for ventilating through a gap between a building tile and a ground tile, and as one example, a building ventilation device provided particularly in a roof ridge is known. .
[0003]
For example, as shown in FIG. 12, a gap is provided at the top of a roof 46 made of rafters, field boards, and the like to form a double-flow roof surface, and this gap naturally increases the heat and odor that stays in the attic. It becomes the roof ventilation passage 47 which rises by force and first gathers and passes. And the auxiliary member 49 which has the 1st ventilation port 48 standingly arranged so that the roof ventilation channel | path 47 may be straddled is provided, and also while providing a clearance gap outside this auxiliary member 49, it is 2nd ventilation port. 50 and a purlin support member 51 that supports the purlin 40 is provided in the center. The auxiliary member 49 and the purlin support member 51 are fixed to the roof 46 with nails or the like (not shown).
[0004]
On the other hand, after fixing the pier 36 in the vicinity of the top of the roof 46, the roof tile 52 is hooked along the pier 36. Further, a passage forming member 56 having a third ventilation port 54 and a fourth ventilation port 55 is fixed to the purlin 40 by a nail or the like (not shown) via a sealing member 53 on the roof tile 52. The roof tile 42 is placed on the passage forming member 56 and fixed to the purlin 40 by a fixing tool 57 such as a long nail or a screw. Further, between the back surface of the roof tile 42 and the passage forming member 56. A ventilation passage 58 is formed.
[0005]
With this configuration, air rising from below toward the top of the roof passes through the roof ventilation passage 47 as indicated by the arrow K, and then zigzags through the first and second ventilation openings 48 and 50. Further, the air is exhausted through the third and fourth ventilation ports 54 and 55 of the ventilation passage 58 (the flow of the air flow is indicated by a solid line arrow) (for example, Patent Document 1).
[0006]
In addition, as another example of a conventional building ventilation device, it is intended to provide a building ventilation device optimal for a corner building or a building in which a roof is directly provided on a corner building or a rafter of a building, An opening provided in the corner of the roof or in the vicinity of the ridge, a ventilation passage material for forming a ridge ventilation passage provided in the opening, and a ventilation communicating with the ridge ventilation passage provided in the opening. A building ventilation means having an opening, a passage forming member provided on the building ventilation means and having first and second ventilation openings, and a corner building tile forming the passage and the passage ( For example, Patent Document 2).

[Problems to be solved by the invention]
However, since the previous ventilation building device of Patent Document 1 is a ventilation device formed by arranging a complicated building ventilation member with a large number of parts, an increase in cost is inevitable. In addition, since the ventilation passage 58 opens outward, in the case of a typhoon or the like, wind and rain invade, resulting in stains on the ceiling and corrosion of the vicinity of the roof ridge. was there.
[0009]
The auxiliary member is provided with a first ventilation port, the purlin support member is provided with a second ventilation port, and the passage forming member is provided with a third ventilation port and a fourth ventilation port. A thin steel plate or a stainless steel plate is drilled by a press or a drill to provide a ventilation opening, and then an assembly process is performed. Therefore, it takes a lot of work and the cost is inevitably high. And if it is going to implement | achieve further cost reduction easily, a thin material will be used, and this will cause the fall of intensity | strength and durability conversely. Furthermore, the loss of the punching material is large, and it has been a problem that the processing effort and cost cannot be overlooked.

An inclined roof tile support portion 7 is provided for mounting, and the inner ventilation port 2 of the inner portal member 3 and the outer ventilation port 4 of the outer portal member 5 are positioned in the longitudinal direction. They are formed so as not to overlap each other.
[0029]
The building ventilation device 1 having such a configuration has a cross section with excellent rigidity and can be extruded with aluminum or resin, thereby ensuring sufficient strength and achieving a significant cost reduction.
[0030]
Further, since the inner ventilation port 2 of the inner portal member 3 and the outer ventilation port 4 of the outer portal member 5 are formed so as not to overlap with each other in the longitudinal direction, the flow of the ventilation flow is zigzag-shaped. Will flow into. Therefore, in contrast to the flow of natural exhaust, for example, even when a storm such as a typhoon reverses instantaneously and tries to enter from the outer ventilation port 4 of the outer gate type member 5, the rainwater component that is more serious is the inner gate type. It collides with the outer wall of the member 3 and is eliminated. Intrusion into the room from the inner ventilation port 2 is prevented, and the airflow component is moderately attenuated and does not reach the room.
[0031]
Moreover, although mentioned later for details, by providing the roof tile support part 7 inclined on both sides of the outer gate type member 5, the upper end portion of the roof tile is placed between the roof tile and the field ground. It is possible to provide a space portion and form the space portion so as to be a ventilation path for the ventilation flow discharged from the external ventilation port 4.

Is done.
[0050]
Example 10
The fixing method of the purlin in the above-described Examples 7 and 8 was a form in which the purlin was attached to the purlin attachment portion formed integrally with the ridge ventilation device. Although the ridge ventilation structure in the present embodiment is a form using the ridge ventilation apparatus 1 shown in FIG. 7 of the sixth embodiment, the ridge tree fixing method directly fixes the ridge tree to the upper member Y of the ridge ventilation apparatus 1. Instead, an independent purlin fixture 44 is disposed between a plurality of the ventilating devices 1 arranged at appropriate intervals in the longitudinal direction of the ridge, and the purlin 40 is supported by the purlin fixture 44. The overall building ventilation structure.
[0051]
The purlin fixing device is not particularly limited as long as it supports and fixes the purlin. However, as a preferred example, as shown in the figure (only the upper half), the bottom portion 29 is erected on the upper side of the column 45 from both ends thereof. 1 and 7 is formed at the lower portion of the support column 45 so as to be along the inclined surface of the base plate 34. It is fixed by.
[0052]
In such a configuration, a clay material 39A such as plaster or clay is placed on the ground tile support portion 7, a ground tile 38 is installed, and the clay material 39A is replenished on the ground tile 38. The building roof 42 is sequentially installed on this to form a building ventilation structure, and the ventilation flow rising from the indoor sequentially passes through the opening 35, the ventilation path 14, and the second ventilation path 15, and finally The point of being discharged to the outside through the gap 43 formed between the roof tiles in each place is the same as in the case of the ninth embodiment. In this embodiment, since the purlin fixing tool 44 is provided independently, there is an effect that the height can be freely selected according to the shape and size of the roof tile 42.
