DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eaves ventilation structure, and more particularly to an eaves ventilation structure capable of performing ventilation of a hut (attic) at the eaves.

[0002]

2. Description of the Related Art When a roof surface is burned in summer sunlight,
The daytime heat stays behind the hut until night, making the room directly below it sultry. To avoid this, it is necessary to provide ventilation openings at the eaves to encourage ventilation behind the hut. in this case,
If the vent area is too small relative to the ceiling area, the ventilation will not be sufficient and the inside of the cabin will not be sufficiently cooled.In winter, the warm and humid air trapped inside the cabin will be cooled by the cold outdoor air. Touch the face and wife's wall,
Condensation occurs. If the condensation is severe, damages such as generation of mold, peeling of the paint, corrosion, etc. will occur.
On the other hand, if the area of the ventilation opening is too large, not only the appearance becomes ugly, but also rainwater blows in from the ventilation opening, which is inconvenient.

[0003] Conventionally, as an eaves ventilation structure capable of preventing rainwater from being blown out from a ventilation opening while ventilating smoothly, Japanese Unexamined Utility Model Publication No. 57-109129 discloses an eaves concealing material with a veneer decorative panel. In which a ventilation hole is provided with a step-shaped eaves ventilating metal fitting and an eaves front cutout material, as disclosed in Japanese Utility Model Application Laid-Open No. 57-172834, comprising a double nose concealing material and a porous material;
In Japanese Patent Application Laid-Open No. 68944/1989, the ventilation is performed by a double structure of the ventilation hole surface of the eaves drain and the ventilation hole surface of the gable drainage. In between, one end is fixed to the back of the fascia,
At the other end, a receiving part for receiving the edge of the eave ceiling material is integrally formed, and a ventilated metal having a vent hole is used.

[0004]

However, Japanese Unexamined Utility Model Publication No. 57-109129 requires a dedicated ventilation metal fitting in addition to the eaves decorative panel.
Japanese Patent Publication No. 34-34 requires an extra nose cover in addition to a dedicated ventilation member (porous body).
Japanese Unexamined Patent Publication No. 944 requires two types of complicated shape drainers and complicated positioning adjustment between the two drainers. In addition, the eaves ventilation hardware of Japanese Utility Model Laid-Open No. 3-113036,
Since the nailing fixing part and the fitting fixing part are different from each other, there is a disadvantage that the working time is long.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a ventilation structure for an eave which can easily perform ventilation of the back of a cabin at the eave by making good use of the accommodation of the eave. And

[0006]

In order to solve the above-mentioned problems, the ventilation structure at the eaves tip according to the first aspect of the present invention has a nose concealing material of a relatively short length and a relatively long nose-covering material on a wooden mouth of a relatively long wing. By attaching the eave ceiling material to the lower end of the rafter while aligning the upper ends, an opening for ventilating the attic is formed between the lower end of the fascia and the tip of the eave ceiling material. In addition, the nose cover, the opening, and the tip of the eave ceiling material are made visible and hidden by a decorative cover material.

[0007] The ventilation structure of the eaves tip according to the second aspect,
While the upper end of the decorative covering material is in contact with the roof base material, a predetermined open end space communicating between the opening and the outside is provided between the lower end of the decorative covering material and the tip of the eave ceiling material. It is characterized by having been provided.

[0008]

According to the structure of the present invention, a ventilation structure at the eaves can be obtained from a relatively long blunt tree, a relatively short blunting material, a simple-shaped decorative covering material, etc. No special parts are required. That is, it is possible to easily perform ventilation of the back of the hut at the eaves with the effort to make good use of the eaves storage. In addition, if the decorative cover material is obtained from a nonflammable and waterproof material, it can contribute to the improvement of the fire resistance and waterproofness of the eaves structure.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a sectional view showing a ventilation structure of an eaves tip according to an embodiment of the present invention, and FIG. 2 is a partial perspective view showing a shape of a decorative cover material used in the ventilation structure of the eaves tip.
The eaves tip shown in FIG. 1 constitutes, for example, a roof part indicated by reference numeral A in FIG.

In FIG. 1, reference numeral 1 denotes a rafter erected between a ridge beam and an eave beam in a state protruding from an eave beam (not shown), and the rafter trees 1 are spaced apart from each other by a predetermined distance, and A plurality of them are installed in parallel. A nose-blocking member 2 having a shorter length than that of the rafter 1 is abutted, nailed, and fixed to the tip of the rafter 1 so that its upper end is aligned with the upper end of the rafter 1. For example, in the case of using a bar tree 1 of 130 mm, a blindfold 2 of 120 mm is used.
It is preferred to use

At the lower end of the rafter 1, a fire-resistant eaves ceiling material 3 such as a gypsum board is directly stretched.
A gap B having a width of, for example, 10 mm communicating with the back of the cabin is naturally formed between the upper surface of the front end portion of the hood and the lower end of the fascia. On the other hand, a base plate 4 such as a particle board or a structural plywood is stretched on the upper end of the rafter 1, and a waterproof paper 5 such as asphalt roofing is stuck on an upper surface of the base plate 4 to be subjected to waterproof treatment. .

A nose-shaped decorative cover material 6 is nailed and fixed to the outer surface of the nose cover 2 via a triangular cover receiving bar 7. The decorative cover material 6 is a nose-shaped bent and long object integrally obtained by bending a PVC steel plate, and as shown in FIG.
