BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eaves ceiling structure having an eaves ceiling on a roof eaves.

[0002]

2. Description of the Related Art Conventionally, in an eaves ceiling structure, an air passage communicating between the eaves back and the outside is formed at a boundary between the eaves ceiling and an outer wall to ventilate the eaves back. For example, JP-A-7-42299 and JP-A-10-131
In the structure of the eave ceiling shown in Japanese Patent No. 321,
A plurality of spacers are interposed between the supporting member and the outer wall supporting the side edge of the outer wall side of the eaves ceiling material at left and right intervals,
It has a configuration in which a member supporting the side edge of the eave ceiling material on the outer wall side and the outer wall are joined with a space therebetween. And in the said structure, the space except the spacer between an outer wall and the said support member is ensured as an air passage which connects the eaves back and the outside, and the eaves back can be ventilated.

In Japanese Patent Application Laid-Open No. 7-42299, a ceiling plate supporting bracket (supporting member) extending right and left along the side edge portion is fitted to a side edge portion on the outer wall side of the ceiling plate. The ceiling plate support is joined to an outer wall to which an exterior material is attached via a spacer. Therefore, the eaves back and the outside can be communicated between the ceiling plate support bracket and the outer wall and between the spacers. The side edge of the ceiling plate on the outer wall side is hidden by a ceiling plate support, and the ceiling plate support functions as a parting material for a boundary between the ceiling plate and the outer wall.

In Japanese Patent Application Laid-Open No. Hei 10-131321, an eaves fixing device is attached to an outer wall via a spacer at a portion above an outer wall to which an exterior material is attached. Has a ridge support for fixing a ridge supporting the eave ceiling to the outer wall, and an eave swallowing part for swallowing an end of the eave ceiling. Therefore, the back of the eaves can communicate with the outside between the eaves fixing fixture and the outer wall and between the spacers. The end of the eave ceiling is hidden by the swallowing part, and the swallowing part functions as a parting material.

By the way, in the eaves ceiling structure as described above, a support member for supporting a side edge of the eaves ceiling material on the outer wall side is joined to the outer wall via a spacer. The structure for attaching the side edges of the ceiling material on the outer wall side to the outer wall is complicated. In addition, in order to attach the side edge of the outer wall side of the eave ceiling material, first, the supporting member had to be attached to the outer wall with the spacer interposed, and the attaching work was troublesome and time-consuming. .

Also, in the above-mentioned Japanese Patent Application Laid-Open No. 7-42299, the ceiling support fitting is joined to the outer wall by a joining member such as a nail, but the ceiling support fitting is so secured that the nail cannot be seen from the outside. The nail is driven into the outer wall via the spacer from the recess into which the end of the ceiling plate is inserted, and the workability is poor. In addition, as described above, the spacer is disposed between the ceiling support bracket and the outer wall, and the spacer and the ceiling support bracket need to be substantially at the same height. The metal fitting does not always function as a parting material, and there is a problem in appearance.

In Japanese Patent Application Laid-Open No. Hei 10-131321, an eaves fixing device having a field edge supporting portion and a swallowing portion is fixed to an outer wall via a spacer, and the field edge is attached to the eaves fixing device. Since the eaves are attached to the edge of the field, it has a complicated structure, which is disadvantageous in terms of cost and workability. Further, since the upper end of the exterior material is lower than the eave ceiling, a parting-off material for hiding the upper end of the exterior material is required, and the configuration is further complicated.
