DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eaves ventilation structure. More specifically, the present invention relates to an eaves ventilation structure that can be easily constructed and can be easily repaired or maintained after the construction.

[0002]

2. Description of the Related Art Hitherto, a structure in which a ventilation member is attached to the eaves of a roof has been known as a structure for ventilation in a backstory or ventilation of a roof ventilation layer. This ventilation member is shown in FIG.
As shown in (1), a support bracket (A) having a U-shaped cross section with ventilation inlets (A) on the upper and lower surfaces is attached to the wall surface (C), and the nonflammable eave ceiling material (D) Insert the edge between the upper and lower surfaces of this support bracket (a), and ventilate the airway (e)
Is formed. Then, a thermal foam material (f) is disposed in the support bracket (a), and in the event of a fire or the like, the thermal foam material (f) expands to block the ventilation path (e), thereby preventing the spread of fire. Such ingenuity is also given. Similarly, a structure in which a ventilation member provided with an air inlet is sandwiched between a space between a nose shield (g) and an eave ceiling material (d) has been proposed.

[0003]

However, in the case of such a conventional eaves ventilating structure, the eaves ceiling material (d) is sandwiched by the support brackets (a), so that the eaves ceiling material is used. (D) Due to errors in the size during the creation, or due to problems during construction, the space for the ventilation path (e) may not be sufficient, and in the worst case, eave ceiling materials (D) causes a problem that the ventilation path (e) is blocked and cannot be ventilated. In addition, since the support bracket (A) is incorporated and attached to the wall (C) and the eave ceiling material (D), the eaves structure including this wall (C) is constructed (carpentry work), and then the support bracket is mounted. (A) must be installed (sheet metal work), and finally, eaves ceiling material (D) must be installed (carpentry work), and there is a problem that the work process is complicated.

Further, the state of the thermal foaming material (f) disposed in the support fitting (a) needs to be inspected periodically, and once foamed, it must be replaced with a new one. In the case of conventional ventilation members, since the ventilation members are built into the plate material that constitutes the eaves, the eaves structure itself is dismantled, the ventilation members are removed, and the thermal foam (f) is inspected or replaced. I had to.

[0005] Such a problem is caused by the problem that the ventilation member is connected to the tip of the eaves, namely, the nose cover (g) and the eaves ceiling (d).
The same applies to the case where it is disposed between the first and second positions. The present invention has been made in view of the above circumstances, and eliminates the drawbacks of the conventional eaves ventilating structure, ensures the ventilation space at the eaves front, and simplifies the construction process. Further, it is an object of the present invention to provide a new eaves ventilation structure that allows easy inspection and replacement of a thermal foam material provided in a ventilation member.

[0006]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems by disposing a heat-foaming material along a row of air inlets provided with a smoke-proof cover having bent pieces at both ends. A ventilation member having an eaves top plate portion provided and a decorative nose cover plate portion extending the eaves top plate portion at a lower end portion is detachably attached to the ventilation space at the eaves end. Provide ventilation structure at the eaves.

Further, in the eaves ventilation structure of the present invention, the eaves top plate of the ventilation member is attached to the attachment member fixed to the base material forming the ventilation space of the eaves. The plate part is locked to the lower end of the makeup nose cover plate part, and only the eaves top part is detachable,
In a preferred embodiment, a fireproof heat insulating material is provided on the makeup nose cover plate portion, the attachment member, and / or the smoke prevention cover body.

[0008]

[Effect] In the eaves ventilating structure of the present invention, after the nose cover, field edge, eave ceiling material, etc., which are the base material constituting the eaves, are constructed by carpentry work, the space between the hood cover and the eave ceiling material is provided. The ventilation member is attached so as to cover the formed ventilation space. Carpentry work and sheet metal work can be performed completely independently, and the work process can be simplified. In addition, since the installation of the ventilation member is the final work of the eaves construction, even if there is a dimensional error of the eaves ceiling material, for example, the ventilation member can be installed after ensuring the ventilation space, and The joints of the eaves ceiling material can be covered and hidden by the eaves top plate part of the ventilation member, and the appearance is good.

Further, the ventilation member can be detached independently without dismantling the base material of the eave by, for example, screwing the eave top plate to an attachment member fixed to a nose cover or a field edge. Inspection and replacement of the internal thermal foam material can be easily performed. In addition, the ventilation member may be configured such that the eaves top plate portion is detachably integrated with the makeup nose cover plate portion, and in this case, only the eaves top plate portion can be removed.

The ventilation member and the mounting member may be provided with a fire-resistant heat insulating material as appropriate depending on whether the construction site is in a fire protection area or a non-fire protection area. Hereinafter, an embodiment will be described with reference to the accompanying drawings, and the eaves ventilation structure of the present invention will be described in more detail.
