A rafter 9 is arranged at intervals in the ridge length direction from the left and right on a ridgepole 8 that is long in the ridge length direction, a roof base material is laid on the rafters 9, and a roof base material as an example of roofing material is laid on the roof base material. The roof is covered with corrugated tiles 10. Place the ridge 1 on the left and right wave tiles 10, 10 across the ridge.
1 and 11 are installed substantially parallel to the ridge length direction.
A draining board 1 is provided over the entire length of the ridge in the ridge length direction across the left and right ridge sills 11, and the ridge opening c communicating with the attic a is closed above it. Draining board 1
A large number of ventilation holes 2 are provided at intervals in the longitudinal direction of the ridge. A large number of supporting metal fittings 12 each formed of a band plate bent into a substantially horseshoe shape are attached to the drain plate 1 at intervals in the ridge length direction. The ridge ventilation tile 3 is made of ceramic and has a substantially horseshoe-shaped cross section. As shown in FIG. 4, one longitudinal end of the ridge ventilation tile 3 is stepped to form a connection recess 5, and the other end is provided with a connection 6 that can fit into the connection recess 5. ventilation tile 3
It is formed at approximately the same level as . A tile ventilation opening 4 is formed in the ridge ventilation tile 3 at a position shifted from the ventilation opening 2 of the draining board 1 in the ridge length direction. A cylindrical leg 14 of a perforated plate 13 is inserted into the tile ventilation opening 4 to attach the perforated plate 13 to the tile ventilation opening 4. Thus, the ridge ventilation tile 3 is placed above the draining plate 1 in the longitudinal direction of the ridge, and is attached to the support fitting 12 with the mounting bolts 15 through the perforated plate 13 while connecting the connection part 6 to the connection recess 5 of the ridge ventilation tile 3.
In such a case, the vents 2 of the draining board 1 and the tile ventilation ports 4 of the ridge ventilation tile 3 are misaligned in the ridge length direction, and rainwater that has entered through the perforations 13 of the tile ventilation ports 4 enters the vents 2. I'm trying not to let it happen. and,
A gap b is formed between the lower side edge of the ridge ventilation tile 3 and the drain plate 1, and rainwater that has entered from the perforated plate 13 of the tile ventilation opening 4 is transmitted through the drain plate 1 and drained from the gap b to the outside. It is arranged so that water can be drained onto the corrugated tiles 10.

As shown in FIG. 2, water return banks 7 are formed on both sides of the drain board 1 over the entire length in the ridge length direction, and these water return banks 7 close the gap b.
It is designed to block rainwater that is blown in and prevent it from penetrating further into the center. In addition, the water return bank 7 is in contact with the lower surface of the connection recess 5 of the ridge ventilation tile 3, and when the ridge ventilation tiles 3 are installed in the ridge length direction, it is easy to maintain the straightness of the ridge ventilation tile 3. The support strength of the ventilation tiles 3 is increased.

A rising piece 16 is provided around the vent 2 of the drain plate 1 to prevent rainwater flowing through the drain plate 1 from entering the vent 2. Further, a water return flange 17 is provided around the upper edge of the rising piece 16 to further prevent rainwater from entering. In addition, the above-mentioned rising piece 16 is attached to the vent 2.
A valve support body 18 is formed in series. The central shaft 21 of the on-off valve 20 is inserted into the guide hole 19 of the valve support 18.
can be inserted freely. Also, on-off valve 20
Guide rods 22 are suspended at intervals in the circumferential direction, and the guide rods 22 are slidably supported by a guide portion on the side of the valve support 18 to prevent the opening/closing valve 20 from wobbling. A coil spring 23 made of a shape memory alloy is disposed across the on-off valve 20 and the valve support 18, and the coil spring 23 is connected to the shaft 2.
It is wrapped in 1. The coil spring 23 made of a shape memory alloy undergoes large reversible displacement due to temperature changes, and when it exceeds a certain (transformation) temperature such as 40°C, martensitic transformation occurs and the coil spring 23 is greatly deformed into a specific shape. For example, when the temperature drops below a certain temperature such as 40°C, it reversibly deforms to its original shape. Shape memory alloys are alloys of nickel, titanium, etc., and their transformation temperature can be changed over a wide range by changing the ratio of nickel to titanium and adding small amounts of other elements. can. Moreover, when it transforms into a specific shape, the force it exerts is about 200 times greater than the force caused by expansion and contraction of a bimetal element of the same size. However, when the ambient temperature exceeds about 40°C, the shape memory alloy coil spring 23 deforms into a specific shape of a certain length, pushes up the on-off valve 20 and opens the vent 2, allowing hot air to flow from the attic to the outside. This system automatically ventilates air during the summer. When the ambient temperature drops to about 40°C or less during rain or winter, the coil spring 23 deforms to its original shape with a certain length, and the on-off valve 2
0 and closes the vent 2 to prevent heating air from escaping and moisture from entering.

[Effect of idea]

In summary, in this invention, water return banks are formed on both sides of the draining board over the entire length of the ridge, so that rain water flows from the gap for drainage between the lower edge of the side of the ridge ventilation tile and the draining board. Even if rain water tries to climb up the drainage board, the water return bank can prevent this, which has the advantage of preventing rainwater from entering. Moreover, since the water return bank is brought into contact with the lower surface of the connecting recess, the ridge ventilation tile can be supported by the drainage board at the connection point via the water return bank.
When constructing ridge ventilation tiles connected in the ridge length direction, there are advantages in that it is easy to achieve linearity of the ridge ventilation tile group, improve workability, and also increase the support strength of the ridge ventilation tiles. be.
