Description of the Related Art Conventionally, in order to ventilate an attic of a building such as a house, a ventilation opening communicating with the inside and outside of the attic is provided in the eaves lower part of the eaves. Conventionally, as an eaves ventilation structure where ventilation holes are provided in the eaves top part to ventilate the attic,
There has been one in which a large number of through holes communicating with the inside and outside of the hut are provided in the eaves ceiling, or a perforated plate having a large number of through holes is provided as a ventilation member in the parting portion of the eaves ceiling.

[0003]

However, in this case, since the ventilation port is formed in a substantially two-dimensional manner on the eaves ceiling, for example, when the typhoon or other strong wind and rain, the ventilation port is There was a problem that rainwater could easily enter the back of the hut. In addition, since the opening of the ventilation port can be seen directly from below the eaves, it has a poor appearance.

The present invention has been made in view of the above circumstances, and provides an eaves ventilation structure which prevents rainwater from entering the back of a shed and prevents the ventilation opening provided at the eaves top from being directly visible from below the eaves. It is provided.

[0005]

The eaves ventilation structure according to claim 1 is provided with a ventilation opening communicating with the inside and outside of the roof of the eave at the eave top, and the ventilation opening has a substantially hollow ventilation inside. A ventilation member including a space, an inner ventilation port communicating from the ventilation space to the back of the hut, and an outer ventilation port communicating from the ventilation space to the outside is provided, and the ventilation member is configured to ventilate the inside and outside of the hut. The eaves-ventilation structure having the above-mentioned structure is characterized in that the ventilation member is provided with a recess opening downward, and the outer ventilation port is located at the back of the recess.

In this eaves ventilating structure, outside air enters the ventilation space from the outside ventilation port of the ventilation member, and further vents from the inside ventilation port into the inside of the attic. It also serves as a trap to prevent intrusion, and since the outside ventilation port of the ventilation member is located deep inside the recess, rainwater will not reach the recess even in strong wind and rain. It is difficult to climb up to reach the outside ventilation port and prevent rainwater from entering more effectively. Also,
By providing the outer ventilation port of the ventilation member at the back of the recess, the outer ventilation port can be made substantially invisible directly from below the eaves.

According to a second aspect of the present invention, there is provided the eaves ventilation structure.
The eaves ventilation structure described above is characterized in that a bent portion is provided between the opening and the back of the recess of the ventilation member.

In this eaves ventilating structure, since the concave portion of the ventilation member is provided with a bent portion between the opening and the back, rainwater blown into the concave portion from below hits the inner wall of the concave portion and is captured. The probability of not reaching the outer vent is increased. Therefore, the effect of preventing the intrusion of rainwater becomes greater. Further, since the recess of the ventilation member is bent from the opening to the back, the outer ventilation opening can be made invisible directly under the eaves.

According to a third aspect of the present invention, there is provided the eaves ventilation structure.
Alternatively, in the eaves ventilation structure according to claim 2, the front lower end of the recess of the ventilation member is positioned lower than the rear lower end.

In this eaves ventilating structure, since the front lower end of the recess of the ventilation member is located lower than the rear lower end, rainwater is less likely to blow into the recess. That is, in the eaves top part, rainwater is sprayed from slightly below the eaves, and it is necessary to go around the lower front end of the recess in order to spray it into the recess. Therefore, the effect of preventing the intrusion of rainwater becomes greater.

According to a fourth aspect of the present invention, there is provided the eaves ventilation structure.
The eaves ventilation structure according to any one of claims 1 to 3, wherein a foam material that expands in volume by heat is provided in the ventilation space of the ventilation member.

In this eaves ventilation structure, when hot air passes through the ventilation member during a fire, the foam material provided in the ventilation space foams due to heat and expands in volume, interrupting ventilation in the ventilation space, and moving to the attic. The spread of fire can be prevented.

According to a fifth aspect of the present invention, there is provided the eaves ventilation structure.
The eaves ventilation structure described above is characterized in that a rib protruding toward the foam material is provided on the inner wall of the ventilation space of the ventilation member.

In this eaves ventilation structure, the ventilation passage is narrowed at the position where the foam material is provided by the rib provided so as to project toward the foam material in the ventilation space of the ventilation member. It will be in the state of doing. Accordingly, in the event of a fire, the foam material foamed and expanded in volume by the heat of the hot air passing through the ventilation space of the ventilation member can quickly catch the ribs and reliably block the ventilation in the ventilation space.

According to a sixth aspect of the present invention, there is provided the eaves ventilation structure.
The eaves ventilation structure according to any one of claims 5 to 5, wherein the ventilation opening is provided between the front end of the eaves and the nose cover in the eaves ceiling, and the ventilation member provided in the ventilation opening is a parting member. It is characterized by being used together as.

In this eaves ventilation structure, the ventilation member is attached between the front end of the eaves ceiling and the nose cover and used as a parting member. In this case, as described above, the outer ventilation port of the ventilation member is below the eaves. Since it cannot be seen from the outside, the appearance as a parting member becomes good.

The eaves ventilation structure according to claim 7 is the structure according to claim 1.
7. The eaves ventilation structure according to any one of claims 6 to 6, wherein the ventilation member is composed of an upper member attached and fixed to the eaves top part by a fastener and a lower member attached and fixed to the upper member. It is characterized by.

Here, the fixing means refers to nails, screws or the like. In this eaves ventilating structure, the ventilation member is composed of an upper member that is attached and fixed to the eaves top portion by a fastener and a lower member that is attached and fixed to the upper member. It is convenient to attach to. That is, since the ventilation member has a ventilation space, in the case where the ventilation member is an integral body, the fixing member is attached to the ventilation member when the fixing member is attached and fixed to the eaves by fixing members such as nails and screws. Since the ventilation space is crushed depending on the position and the appearance shape is distorted, the ventilation space must be avoided, and the fixing position of the fixing tool is restricted. On the other hand, in the configuration as described above, the ventilation space is formed between the upper member and the lower member by first attaching the upper member to the eaves part with the fastener and then attaching the lower member to the upper member. Therefore, it is possible to install the fixing tool in the ventilation space, and therefore the fixing tool does not cause the ventilation space to be crushed and the external shape is distorted, and the fixing position of the fixing tool is not restricted. The fastener can be attached at a position most suitable for attaching and fixing the ventilation member.
