Description

[Detailed description of the invention] The present invention relates to a roof eave structure.

Conventionally, as shown in FIG. 1, for example, such an eave structure is constructed by constructing a nose board 8 fixed to the tip of a oak tree 2 that serves as a support for a roofing material 12 at a construction site, and a front upper part of an outer wall 1. In the meantime, a base frame 9 supported by hanging trees 7 is assembled, and the soffit panel 14 is fixed to the lower surface of the base frame 9 with nails 13, and then fixed with the front green parting edge 11. was forming.

Therefore, during construction, the composition of the base frame 9 supported by the hanging trees 7, the fixing of the eave ceiling panel 14 with nails 13 and the parting edge 11, the processing of nail heads, etc. are time-consuming and work efficiency is reduced. In addition, since the soffit area is covered by the soffit 101, ventilation is poor and fog is likely to form. The purpose of the present invention is to eliminate the need for the composition of the base frame supported by hanging trees, the fastening of the eave ceiling panel with nails, the fixing of the cut edge, and the treatment of nail heads during construction. To provide an eaves structure that improves efficiency, allows good ventilation in the eaves, and prevents dew condensation.

The feature of the eaves structure of the present invention is that, as shown in FIG. 4b is iron-fitted to the fitting groove 3a of the beam cover 3, and the tip 4a is fixed to the barrel wood 2 with a nail 13, and the nail head of the nail 13 is connected to the nose board 8 and the tip 4a of the soffit material 4. A base end 5b bent in a U-shape of a ventilation plate 5 having a ventilation hole 5a interposed between
The front end 5c of the ventilation plate 5 is supported and fixed by the L-shaped lower edge 6a of the decorative cover 6 fixed to the front surface of the nose plate 8. In the illustrated embodiment of the present invention, 1 is an outer wall of a building, 3 is a beam cover fixed to the upper front surface of the outer wall 1, and a steel groove 3a is provided in the length direction. Reference numeral 4 denotes a pre-panelled eaves soffit material formed by pasting an eave soffit panel material on the lower surface of the frame material with an adhesive, and its base 4b is fitted with a steel plate in the joint groove 3a of the beam cover 3. Further, the tip portion 4a is fixed to the barrel tree 2 with a nail 13.

5 is a ventilation plate 5 with a ventilation hole 5a interposed between the nose plate 8 and the tip 4a of the soffit material 4, the front end 5c of which is bent slightly forward and downward, and the base 5b is U-shaped. It is bent. A decorative cover 6 is fixed to the front surface of the nose plate 8, and the lower edge 6a of the decorative cover 6 is bent into an L-shape.

During construction, first, the beam cover 3 provided with the iron groove 3a is fixed to the upper front surface of the outer wall 1.

Next, the base 4b of the paneled soffit material 4 is attached to the beam cover 3.
At the same time as fitting the saddle fitting groove 3a of the saddle fitting groove 3a, the tip part 4a
It is attached along the lower surface with nails 13. Next, the nail head of the nail 13 fixed to the tip 4a of the soffit material 4 is attached to the nose plate 8.
A ventilation hole 5a interposed between the end portion 4a of the eave ceiling material 4 and
After covering with the proximal end 5b bent in a U-shape of the ventilation plate 5 having a
The front end 5c of the ventilation plate 5 is supported and fixed by the lower edge 6a bent in the shape of a letter. In this way, the present invention fixes a beam cover provided with a matching groove on the upper front surface of an outer wall, and makes the base of the paneled soffit material compete with the fitting groove of the beam cover, and the tip part is made of tall wood. fixed with nails, the nail heads of the nails are covered with the U-shaped bent base end of a ventilation plate having ventilation holes interposed between the nose board and the tip of the soffit material, and The front end of the ventilation plate is supported and fixed by the L-shaped bent lower green of the decorative cover fixed to the front of the nose plate, so after fixing the beam cover and fixing the soffit material, The soffit can be formed by simply covering the tip of the soffit material with the base end of the ventilation board and supporting the front end of the ventilation board at the lower edge of the decorative cover. This eliminates the need for the composition of the base frame, the fixing of eave ceiling panels with nails, fixing with parting greens, and treatment of nail heads, which simplifies the process and improves work efficiency. Good ventilation is achieved by allowing outside air to flow into the soffit through the ventilation holes in the ventilation board interposed and fixed between the roof and the tip of the soffit material.
It is possible to reliably prevent fog from forming on the eaves.
