However, the above-mentioned conventional method of discharging from a chimney increases the time and labor for construction and cleaning, and also has a large effect on the appearance of the building, leading to an increase in cost, which leads to an increase in workability and rainfall. Was also a problem. Further, in a roof tile building, particularly a corrugated tile, etc., a crown tile as shown in FIG. 4 was used, so that ventilation from the building was difficult.

The present invention focuses on such a conventional problem. A gap is provided between the roof base plates, and a ridge, a ridge drainer, a face iron plate, and the like which support crown tiles are provided above the roof base plate. By using a devised attachment part, a sufficient exhaust volume from the indoor to the ridge is ensured, and a tiled ridge structure with a good appearance and good operability and a vaulted backside ventilation system are provided.

[0005]

In order to achieve the above-mentioned object, a roof tile structure according to the present invention is a roof tile having a semicircular longitudinal section and supported by a purlin attached to a field board. Providing a gap between the baseboards, provided in contact with the baseboard surface and the purlin on both sides of the gap between the baseboards, a drainage drain having a ventilation port,
The gist of the present invention is that it is composed of a face-plated iron plate having a ventilation hole, which is provided in contact with the drainage drain and the corrugated tile.

[0006] The gist of the tiled roof structure according to the present invention is that the ventilation opening of the face iron plate has a horizontally long shape and a height of 10 mm to 20 mm.

[0007] The attic ventilation system according to the present invention forms a gap between the floor boards of the ridge, and drains a ridge with a ventilation port and a face iron plate with a ventilation port, a purlin,
The gist is to install roof tiles and exhaust air from behind the hut from the gap between the baseboards to the outside through the ventilation opening of the above-mentioned iron plate and the ventilation opening of drainage.
