Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ridge ventilation structure for performing ventilation inside and outside a building in a ridge portion of a roof.

[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 4 and 5, a ridge ventilation structure has been known in which a ridge portion of a roof is ventilated inside and outside the building. In the ridge ventilation structure, a ventilation opening (b) is formed in the ridge portion of the roof base (a), and a head tree (c) is arranged on both sides of the ventilation opening (b) and on the head card (c). A mounting board (d) is disposed and fixed to the both sides, and opposing edges of the mounting boards (d) on both sides are connected by a erection bar member (e), and a ventilation hole (f) is provided. Both side edges (h) of the ridge cover (g) covering the upper part of (b) are respectively coupled and fixed to the outer end edges (r) of the both mounting boards (d).

In the ventilation structure for the ridge, roof tiles (nu) are laid on the roof substrate (a), and a headstock (ha) is placed on the roof tiles (u). ) Is provided along the mounting board (d), and the mounting board (d) is fixed to the roof substrate (b) from above the mounting board (d) by fasteners (l) such as screw nails and driving nails. ) Is fixed to both sides of the ventilation opening (b) together with Kasaki (c). In addition, the erection bar material (e) is made of a flexible strip-shaped thin plate, and both mounting boards (d)
, Two ends of the erection bar member (e) are riveted to opposite edges of the mounting substrate (d).
Each of them is coupled and fixed by a coupling tool (e) such as a screw. In addition, a large number of elongated ventilation holes (f) are formed in parallel on both sides of the ridge cover (g) along both side edges (h) of the ridge cover (g). The mounting substrate (d), the erection bar material (e), the ridge cover (g), etc. are all formed of metal plates.

In this case, the erection bar material (e) is bent, the mounting boards (d) on both sides of the erection bar material are inclined and arranged so as to correspond to the slope of the roof, and the ridge cover (g) is also attached to the ridge top. The corner portion (wa) is bent so that both side portions thereof are similarly deformed so that both side edges (h) of the ridge cover (g) are located on the outer edge (li) of the mounting substrate (d). Both are bonded and fixed by a fastener (l) which is polymerized and is inserted into the polymerized portion. In addition, a ventilation path that connects the ventilation opening (b) and the space between the opposing edges of both mounting boards (d) and the ventilation hole (f) of the ridge cover (g) is formed, and inside and outside the building through the ventilation path. Ventilation is performed.

[0005]

However, in the above-mentioned conventional technique, the ridge cover (g) is bent and deformed at the ridge top corner (wa) when the roof slope is dealt with. Along with this, both side edges (h) of the ridge cover (g) that are overlapped on the outer edge (i) of the mounting substrate (d) are also bent and deformed. Since the cover (g) of the same building was firmly formed for the purpose of use, it was a very difficult work that required skill and required a lot of skill. Further, even though the ridge cover (g) is firmly formed, it is only fixed at both side edges (h), so that it is likely to be dented and deformed when an external force is applied to its middle part.

Therefore, the applicant of the present invention first considered a building ventilation structure as shown in FIG. 6 (preliminary example). That is, in the ridge ventilation structure, a ventilation opening (b) is formed in the ridge portion of the roof base (a), and a head tree (c) is arranged on both sides of the ventilation opening (b) and at the same time on the head card (c). A mounting board (d) is arranged and fixed to the building, a support (ta) is vertically installed and fixed on the mounting board (d), and a ventilation hole (f) is provided to cover the ventilation opening (b) above. The middle part of the cover (g) is joined and fixed to the upper part of the support (t).

[0007] In the ridge ventilation structure, the mounting boards (d) on both sides are continuously formed integrally through an intermediate plate part (ye) which is bendable in the middle part and has a vent hole (f). Department (Yo)
The middle part is bent, and the mounting boards (d) on both sides thereof are arranged and fixed so as to incline so as to correspond to the slope of the roof. or,
The support body (ta) is formed in a gate shape, and an attachment piece portion (le) that is bent outward and protrudes is formed at the lower ends of both leg piece portions, and the both attachment piece portions (le) are fixed. It is fixed together with the mounting board (d) and the head board (c) on both sides by the tool (l).
On both sides of the upper part of the support (Ta), the backsides of both sides of the middle part of the ridge cover (g) are placed, and tapping screws (so) are screwed from above the ridge cover (g) at the placing portion. As a result, the cover (g) of the same building is coupled and fixed to the upper part of the support (ta).

Therefore, in the ridge ventilation structure, the ridge cover (g) supported by the support (ta) is easily attached without being bent and deformed even when the roof slope is different, and , The middle part of the same building cover (g) is firmly fixed by being joined and fixed to the upper part of the support (ta), and it is difficult for it to be dented and deformed even when external force is applied. However, in this case, since the ridge cover (g) is supported by the support (ta) in the middle part thereof, both side edges (h) of the ridge cover (g) are shaken by being swung by strong wind. It is easy to move and may cause rainwater to enter or the cover (g) of the same building to come off.

The present invention was invented in order to solve the problems in the above-mentioned conventional techniques and prior examples, that is, the problem is that the ridge cover is bent and deformed even when the roof slope is different. It can be easily attached without causing the ridge cover to be firmly supported, the middle portion of the ridge cover is firmly supported and is unlikely to be dented and deformed, and both side edges of the ridge cover are securely fixed so as not to swing. It is to provide a wing ventilation structure.
