Description

[Detailed description of the invention] [Technical field] The present invention relates to a ventilation ridge structure that provides ventilation in the ridge.

[Background technology]

Conventionally, as shown in FIGS. 1 and 2, a vent 13' that penetrates vertically is provided in a drain plate 3' disposed across the ridge of the roof, and a ridge ventilation hole is provided above the drain plate 3'. A tile 1' is provided, and a tile ventilation opening 2' is provided in the ridge ventilation tile 1' at a position shifted in the ridge length direction from the ventilation opening 13' formed in the draining board 3', and the position is shifted in this way. In a ventilation ridge structure in which ventilation is performed in the ridge while preventing rainwater from entering the attic a' through the vent 13' and the tile ventilation vent 2', the ventilation ridge is ventilated from the tile ventilation vent 2'. It is constructed so that the rainwater that has entered can be drained laterally through a drainage plate 3'. However, in such a configuration,
There was a problem in that rainwater entered from the connecting part of the draining plates 3', 3' connected in the longitudinal direction of the ridge and dripped into the attic a'.

[Purpose of invention]

The present invention was developed in view of these problems, and its purpose is to prevent rainwater from entering the connection part of the drain plate, and to drain it even if it occurs. The objective is to provide a ventilation building structure that allows for

[Disclosure of invention]

In the present invention, rainwater that enters from the tile ventilation opening 2 of the ridge ventilation tile 1 is received by the draining plate 3 constructed under the ridge ventilation tile 1 in the ridge length direction across the ridge, and the rainwater is transferred to the draining plate 3. This is a ventilation building structure configured to drain water in a direction substantially perpendicular to the length direction of the building.
At one end 4 in the longitudinal direction of the ridge, its tip edge 5
A protrusion 6 is provided in a direction substantially perpendicular to the ridge length direction at a position deeper than the protrusion 6, and a drainage groove 7 is formed in a direction substantially perpendicular to the ridge length direction on the tip side of the protrusion 6. This relates to a ventilation ridge structure in which the other end 8 of the plate 3 is stacked on the one end 4 and its tip is brought into contact with the protrusion 6, and by configuring it in this way, the above purpose can be achieved. I was able to achieve this.

Embodiments of the present invention will be described in detail below with reference to the drawings.

Rifles 10 are arranged at intervals in the ridge length direction from the left and right on the ridgepole 9 which is long in the ridge length direction, and the rafters 1
A roof base material is laid on top of the roof base material 0, and corrugated tiles 11 as an example of roofing material are covered on this roof base material. Ridge sills 12, 12 are constructed substantially parallel to the ridge length direction on the left and right corrugated tiles 11, 11 with the ridge in between. A draining board 3 is provided over the entire length of the ridge in the ridge length direction across the left and right ridge sills 12, and the ridge opening c communicating with the attic a is closed above it. Ventilation holes 13 are provided in the drainage board 3 at intervals in the ridge length direction.
There are many. A large number of supporting metal fittings 14 each formed of a band plate bent into a substantially horseshoe shape are attached to the drain plate 3 at intervals in the ridge length direction. The ridge ventilation tile 1 is made of ceramic and has a substantially horseshoe-shaped cross section. A connection recess 15 is formed at one end in the length direction of the ridge ventilation tile 1, and a connection part 16 that can fit into the connection recess 15 is formed at the other end at approximately the same level as the ridge ventilation tile 1. be. The ridge ventilation tile 1 has a vent 13 on the drainage board 3.
The tile ventilation openings 2 are formed at different positions in the ridge length direction. The cylindrical leg 1 of the perforated plate 17 is installed in the tile ventilation opening 2.
8 is inserted and the perforated plate 17 is attached to the tile ventilation opening 2. Therefore, the ridge ventilation tile 1 is placed above the draining board 3 in the ridge length direction, and the connection part 16 is placed in the connection recess 15 of the ridge ventilation tile 1.
It is attached to the support fitting 14 with a mounting bolt 19 through a perforated plate 17 while connecting the two. In such case,
Ventilation port 13 of draining board 3 and tile ventilation port 2 of ridge ventilation tile 1
The position of the ridge is different from that in the lengthwise direction, and the rainwater that entered through the perforated plate 17 of the tile ventilation opening 2
I am trying not to reach 3. A gap b is formed between the lower side edge of the ridge ventilation tile 3 and the drain plate 3, and rainwater that has entered from the perforated plate 17 of the tile ventilation opening 2 is transmitted through the drain plate 3 and from the gap b. It is arranged so that water can be drained onto the corrugated tiles 11 outside.

Then, at one end 4 in the ridge length direction of the draining board 3, a protrusion 6 is provided in a direction substantially perpendicular to the ridge length direction at a position deeper than the tip edge 5 of the drain plate 3, so that water can be drained away from the protrusion 6 toward the tip side. The groove 7 is formed in a direction substantially perpendicular to the ridge length direction. By stacking the other end 8 of the adjacent drain plate 3 on the one end 4 and bringing its tip into contact with the protrusion 6, construction can be carried out quickly while keeping the overlapping margin constant. Because of the stripes 6, it is difficult for rainwater to enter the overlapped portion, and even if it does, the rainwater will flow through the drainage grooves 7 and be drained to the corrugated tiles 11. In addition, as shown in FIG. 7, the drainage groove 7 may be placed close to the protrusion 6.

A rising piece 20 is provided around the vent 13 of the drain plate 3 to prevent rainwater flowing through the drain plate 3 from entering the vent 13. Furthermore, a water return collar 21 is provided around the upper edge of the rising piece 20 to further prevent rainwater from entering. Further, a valve support body 22 is formed in the vent hole 13 in series with the above-mentioned rising piece 20. A central shaft 25 of an on-off valve 24 is slidably inserted into a guide hole 23 of the valve support 22. Further, the on-off valve 24 is provided with guide rods 26 at intervals in the circumferential direction.
The guide rod 26 is slidably supported by the guide portion on the side of the valve support 22 to prevent the opening/closing valve 24 from wobbling. A coil spring 27 made of a shape memory alloy is disposed across the on-off valve 24 and the valve support 22.
is wound around the shaft 25. The coil spring 27 made of a shape memory alloy undergoes large reversible displacement due to temperature changes, and when it exceeds a specific (transformation) temperature such as 40°C, martensitic transformation occurs and the coil spring 27 is greatly deformed into a specific shape. For example, when the temperature falls 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 takes on a specific shape through transformation, the force exerted is approximately equal to that of the expansion and contraction of a bimetal element of the same size.
It is more than 200 times. However, the ambient temperature is about 40
℃, the shape memory alloy coil spring 27 deforms into a specific shape with a certain length, and the on-off valve 24
The vent 13 is opened by pushing up the attic, and the steam is discharged from the attic to the outside, thereby automatically providing ventilation in the summer. When the ambient temperature drops to about 40°C or less during rain or winter, the coil spring 27 deforms to its original shape of a certain length, lowers the on-off valve 24 and blocks the vent 13, preventing heating air from escaping. This is to make sure that it stays clean and that moisture does not get in.

[Effect of idea]

In summary, in the present invention, a protrusion is provided in a direction substantially perpendicular to the ridge length direction at one end of the draining board in the ridge length direction, at a position deeper than the tip edge, so that the ridge is adjacent to the ridge length direction. By bringing the tips of the draining plates into contact with each other, it is possible to improve workability while keeping the overlapping allowance constant, and the protrusions can suppress rainwater from entering the overlapping edges of the draining plates. Moreover, since there is a drainage groove running in the lengthwise direction of the ridge on the tip side of the ridge, even if rainwater should infiltrate into the overlapping part, it can be drained away through the drainage groove, and the rainwater will flow to the back of the attic. It has the advantage of being able to reliably prevent infiltration.
