On the upper surface side of the first and second decorative rafters 14 and 20 of the eaves edge frame 12, an eaves top plate 30 which is a metal decorative plate is fixed integrally.
[0010]
A base end portion of an H-steel cantilever beam 24 is fixed to the building casing 10 in a horizontal direction slightly downward toward the outside. The protrusion direction front end portion 24a of the cantilever beam 24 is formed with a narrow vertical width in order to secure a space where the second decorative rafter 20 is located. A connecting material 26 is welded to the cantilever beam 24, and a lower end portion of the connecting material 26 is welded to a connecting material 28 fixed to the upper surface of the eaves frame 12, so that the eaves frame 12 is cantilevered 24. Are integrally held and fixed.
[0011]
Each member of the eaves frame 12 is formed by cutting a metal plate such as an aluminum plate or a stainless steel plate into a predetermined length and bending it into a hollow shape, and fixing each member with bolts and nuts or welding them. It has been. The surface exposed to the outside is subjected to an acrylic resin baking process, a fluorine process, or the like.
[0012]
A roof base material 34 is laid on the upper part of the eaves frame 12 via a horizontal member 32, and tiles 36 are arranged on the upper surface of the roof base material 34.
[0013]
The eaves frame 12 is formed in the shape of each eave according to the part of the building. For example, as shown in FIG. 2, a corner portion 42 centering on the corner tree 40 is also integrally formed.
