[0002]

2. Description of the Related Art The prior art relating to a roof ventilation system, which is related to the present invention, is disclosed in Japanese Patent Application Laid-Open No. 7-489.
No. 09, a roof ventilation system, and Japanese Patent Laid-Open No. 8-68172, a ridge ventilation structure. The contents will be described. An object of the first invention is to improve the waterproofness and moistureproofness by closing a ventilation passage in rainy weather or when humidity is high. That is,
In a ventilation device for a roof provided with a ventilation passage for performing indoor ventilation, a hygroscopic expansion member that expands by absorbing moisture and closes the ventilation passage is provided in the ventilation passage. Next, another object of the present invention is to increase the amount of ventilation by expanding a negative pressure region where a differential pressure is large in a ridge ventilation structure in which a ridge roof material main body is disposed on a ridge roof base member. That is, a ridge consisting of first and second inclined pieces having a large number of exhaust ports and first and second leg pieces on a ridge roof base member having a ventilation port attached across the roof ridge.

With such a configuration in which a lightweight cover or ridge roof material body is laid, the load applied to the field board and the rafters is small, so that there is no problem even if the opening is left as it is. However, in the case of a relatively heavy roof tile, such as the clay roof tile aimed at by the present invention, if the opening is left as it is, a load is applied to the field board and the rafter, and there is a problem that the durability is lacking. In addition, there is a problem that if the opening is left as it is, the end of the rain is poor, which may cause the occurrence of rain leakage.

[0004]

A second object of the present invention is to provide an optimum structure as a ventilation passage material or to enable simple construction.

[0007] A second aspect of the present invention is a ridge ventilation device in which the ventilation passage member is formed by a frame, and first and second openings and a cavity formed in the frame.

A third object of the present invention is to simplify the equipment of the ridge ventilation means or to facilitate the installation thereof.

According to a third aspect of the present invention, the ridge ventilation means has a first auxiliary member having a ventilation port provided on a roof of a corner ridge or a ridge, and a second auxiliary member having a ventilation port laid across the first auxiliary member. It is a ridge ventilation device composed of members.

A fourth object of the present invention is to provide a stable roof tile for a corner ridge tile or a ridge tile.

According to a fourth aspect of the present invention, there is provided a ridge ventilation device having a configuration in which a corner purlin receiving piece or a purlin receiving piece is provided on the second auxiliary member.

Communicated. Therefore, the ridge ventilation passage → the passage portion of the first auxiliary member and its ventilation port → the gap between the first auxiliary member and the second auxiliary member → the communication with the outside air via the ventilation opening of the second auxiliary member.
For the second auxiliary member of the ridge ventilation means, a roofing method of directly laying a corner ridge tile or a ridge tile, or a roofing method of laying a corner ridge tile or a ridge tile on a second corner ridge tree / second ridge tree, etc. adopt.

In some cases, a corner building tile or a passage forming member is provided between the roof tile and the roof tile to communicate with the ventilation port of the building ventilation means. That is, a tunnel-type passage is formed between the passage forming member and the corner ridge roof tile or the ridge roof tile, and one end opening of the passage (the first ventilation opening of the passage forming member) is used as a roof ventilation passage, and the other end of the passage. Opening (the second ventilation port of the passage forming member) to outside air,
Let each communicate. As a result, the ventilation port of the ridge ventilation means (second auxiliary member) → the roof ventilation passage → the first passage forming member
Ventilation port → passage → communicate with outside air via the second ventilation port of the passage forming member.
