Description

The present invention relates to an eaves structure in which a nose-hiding decorative member having a vent is attached to the nose-hiding of the eaves so that the space in the attic of the house can be ventilated through the vents.

As an eaves structure capable of ventilating the attic space by providing ventilation holes in the nose cover veneer, for example, as shown in FIG. 7, the attachment surface portion of the nose cover veneer 101 attached to the nose cover 100. The lower end of 102 is bent backward to form a ventilation chamber 103 below the nose cover 100, and a ventilation hole 104 is provided in front of the ventilation chamber 103 so that outside air passes through the ventilation chamber 103 to the attic space 105. In addition to being provided so as to flow in, a shielding plate 106 that partitions the space above the room in the front and rear is arranged in the ventilation chamber 103, and a heated foam material 107 is attached to the lower end of the shielding plate 106 to heat the ventilation chamber 103 in the event of a fire. A structure is known in which the ventilation path in the ventilation chamber 103 is blocked by the expansion of the foam material 107 to prevent flames and hot air from entering the attic space 105.

According to the illustrated eaves structure, the attic space 105 can be sufficiently ventilated by taking in outside air from the ventilation holes 104, and the heated foam material 107 that has expanded due to heat in the event of a fire is inside the ventilation chamber 103. By blocking the ventilation path, it is possible to block the inflow of outside air from the ventilation hole 104 and effectively prevent flames and hot air from entering the attic and spreading the fire in the house (for example, Patent Document 1, 2).

Recently, so-called "zero eaves houses", which have no eaves or have short eaves, have been widely adopted. "Zero eaves housing" is relatively often used for houses built in narrow areas such as urban areas. In such a densely populated area, when a fire breaks out, the fire spreads from the house from which the fire broke out to the adjacent house, and the damage is likely to spread. It is required that the fire protection performance of the house is higher than that of the house built in the suburbs that can be secured.

The above-mentioned eaves structure has good functions of ventilating the attic space and blocking outside air and flames in the event of a fire, but when this is applied to a "zero eaves house" in a densely populated area, both functions are available. The fire protection performance of the house is that it is installed in a structure that has improved the above, especially in the case of a fire, that it is installed in a structure that can surely block the ventilation path from the ventilation hole to the attic space in a short time. It is essential to increase the level of fire.

As a measure to enhance the ventilation path blocking function in the event of a fire in the eaves structure, for example, the amount of the heated foam material that expands in response to the heated outside air is increased, the ventilation path is narrowed, or the number of ventilation holes is reduced. It is possible to reduce it.
However, if the installation position of the former is not appropriate, simply increasing the installation amount of the heated foaming material may reduce the ventilation function or take time to expand, and the latter. It is clear that the ventilation function is impaired. Even if an appropriate amount of heated foam material is installed on the ventilation path, there is a gap between the expanded heated foam material and the ventilation chamber surface depending on the inner surface shape of the ventilation path surrounding it, that is, the shape of the ventilation chamber. There is a risk that the outside air flowing in from the ventilation holes will not be sufficiently blocked.
In order to more reliably shut off the ventilation path in the event of a fire, it is necessary to improve the shape of the ventilation chamber forming the inner surface of the ventilation path and then carefully examine the installation position of the heated foaming material. In addition, the construction of the eaves part where the eaves structure is attached needs to be a simple work in combination with the fact that it is built in a narrow area.

In view of such problems of the prior art, the present invention has an eaves structure in which a nose-hiding decorative member provided with a ventilation hole for ventilating the attic space is attached to the nose-hiding, and is below the nose-hiding. By improving the shape of the ventilation chamber provided in the building and selecting the installation position of the heated foam material, it is possible to improve the disaster prevention performance of the house by ensuring that the ventilation path of the outside air is cut off in the event of a fire without deteriorating the ventilation function. Make it an issue.
Further, the present invention makes it possible to attach an eaves structure having a good ventilation function and a function of blocking the ingress of outside air and flames in the event of a fire to the eaves of a "zero eaves house" by simple construction. Make it an issue.

In order to solve the above problems, the present invention comprises a nose concealment decorative member having a front side surface portion fixed to the front surface of the nose concealment and a lower side surface portion protruding downward from the nose concealment from the lower end of the anterior side surface portion, and a lower part of the nose concealment. A ventilation chamber leading to the attic space is formed below the nose cover with the end support member fixed to the outdoor wall of the house and supporting the end portion of the lower side surface portion of the nose cover decorative member, and the front side surface of the nose cover decorative member. It is an eaves structure that is configured so that the outside air that has entered the ventilation chamber through the ventilation holes formed in the part flows into the attic space.
The ventilation chamber is divided into a plurality of spaces by a partition member, and adjacent sections are communicated with each other through a ventilation hole formed in the partition member.
A configuration in which a heated foam material is attached to at least the upper surface of the lower side surface portion of the decorative member close to the ventilation hole formed in the nose-hiding decorative member and the upper surface of the partition member close to the ventilation hole formed in the partition member. It is characterized by having.

According to this, the outside air enters the ventilation chamber through the ventilation holes formed in the nose concealment decorative member, and further flows into the attic space through the ventilation holes formed in the partition member. It is possible to prevent air from staying in the attic space due to the inflow of outside air, and to ventilate by the outside air that has flowed into the space. Since the ventilation chamber is divided into multiple spaces by partition members, even if the outside air vigorously enters the ventilation chamber through the ventilation holes during strong winds, it collides with the partition members and loses momentum, so the inflowing outside air can be removed. There is no such thing as a love for the attic space.
In addition, the heated foam material is attached at a position close to the ventilation hole formed in the nose concealment decorative member, and the heated foam material is also attached close to the ventilation hole formed in the partition member. Since at least two heated foam materials are installed on the ventilation path in the ventilation room, when a fire breaks out in an adjacent house and the resulting flame or hot air enters the ventilation room through the ventilation holes, each heated foam material is heated. By expanding the air, the ventilation path leading to the attic space is completely blocked, and it is possible to prevent flames and hot air from entering the attic from the ventilation room and prevent the house from spreading. It is preferable that at least two heat foaming materials are arranged at appropriate intervals along the ventilation path from the ventilation hole formed in the nasal cover veneer to the attic space through the ventilation chamber. Three or more may be arranged as long as the ventilation function is not impaired and the material cost is not increased.

In the eaves structure having the above structure, a partition member formed by arranging partition plates having ventilation holes on the surface so as to face each other vertically is installed in the ventilation chamber, and the ventilation chamber is a space above the partition member and a space between the upper and lower partition plates. A heat foaming material may be attached to the upper surface of the lower partition plate among the partition plates that are partitioned in the space below the partition member and are arranged so as to face each other above and below.
According to this, the partition members are formed in a box shape by arranging the partition plates vertically and vertically, and the outside air can flow from the ventilation chamber into the attic space through the ventilation holes formed in both partition plates to ventilate. can. In the event of a fire, the heated foaming material attached to the inside of the box-shaped partition member expands by receiving the heat of the inflowing outside air, so that the expanded heated foaming material fills the space between the upper and lower partition plates, and both partition plates. It is possible to seal the ventilation holes formed in the above with a heated foaming material to surely block the ventilation passage of the outside air.

When the partition member is formed in a box shape, the ventilation holes formed in both partition plates arranged above and below the partition member are located at positions where the upper and lower partition plates are staggered from the outer wall of the house along the eaves direction. Each of them is provided, and the heated foam material is preferably attached to the upper surface of the lower partition plate and below the ventilation holes formed in the upper partition plate.
According to this, the outside air that has flowed into the ventilation chamber enters the inside of the box-shaped partition member through the ventilation holes of the lower partition plate, and further flows out from the ventilation holes of the upper partition plate to the space in the roof. Since the ventilation holes formed in the partition plate of the above are provided at positions that are staggered in the front and rear, the ventilation passage of the outside air in the partition member becomes a passage that meanders between the upper and lower ventilation holes, and the lower partition plate Since the heated foam material attached to the upper surface is located below the ventilation holes formed in the upper partition plate, the outside air heated in the event of a fire flows in the box-shaped partition member while meandering, and the heated foam material is used. The entire surface of the heated foam material can be efficiently heated and expanded, and the ventilation path of the outside air in the ventilation chamber can be reliably blocked by the expanded heated foam material.

In the eaves structure having the above structure, a protrusion protruding downward is provided at the bottom of the partition member, and the heated foam material attached to the upper surface of the lower side surface of the nose-hiding decorative member is located below the protrusion. It is preferable that it is configured in.
According to this, a protrusion protruding downward from the partition member is located above the heated foaming material to narrow the ventilation path of the outside air above the heated foaming material, and the outside air flowing into the ventilation chamber from the ventilation hole is It flows into the ventilation holes of the partition member through the narrow ventilation passages on the heated foam material. Since the heated outside air that flows in during a fire passes through a narrow passage on the heated foaming material, the density of the outside air that heats the heated foaming material is high, and a large amount of outside air comes into contact with the heated foaming material to heat it and heat it. It is possible to efficiently expand the foaming material in a short time and surely block the air passage of the outside air under the partition member.

Further, in the eaves structure having the above structure, the partition member is joined to the front end of the nose cover together with the nose cover decorative member and fixed to the front end of the eaves structure so that the partition member can be attached to the eaves of the house by simple construction. It is preferable to have a structure in which a fixed surface portion is provided, and a joint piece that engages with a joint piece provided on the end support member is provided at the rear end portion.
Further, the end support member and the partition member may be integrally provided.
