DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an eaves ceiling mounting structure in a prefabricated house or the like.

[0002]

2. Description of the Related Art Conventionally, in the eave ceiling of a front entrance porch portion of a house, a decorative material and an eave girder are disposed below an eave beam and an eave girder base, and divided into a portion inside the porch and an eave tip portion. Had different eaves ceiling panels.

[0003]

In the conventional eave ceiling mounting structure, a decorative material and an eave girder decorative material are arranged below the eave beam and eave girder base, and the eave ceiling is divided into a portion inside the porch and an eave tip portion. Since the boards were attached, there was a problem that the appearance of the eave ceiling became poor, and the height of the eave ceiling plate was different between the inside of the porch and the eaves tip. It is also conceivable to install eaves and ceiling boards continuously, avoiding the eaves and eaves girder bases. However, the installation height of the eaves and ceiling eaves is reduced by avoiding the eaves and eaves girder bases. A new problem arises in that the ceiling is low.

SUMMARY OF THE INVENTION An object of the present invention is to provide an eaves ceiling mounting structure that has good appearance, can keep the eaves ceiling height level constant without lowering the eaves ceiling height, and can firmly support the eaves ceiling plate. It is to provide.
