Further, since both the drain member and the rafter are fixed on the support member by the fixing metal fittings, workability is improved.
A heavy-roof roof can be constructed, and even if the fixing metal fittings are thick, they can be installed at multiple locations in the eaves direction of the drainage members and thick-walled rafters, so that both drainage members and rafters can be used. If so, it is necessary to use a thick member,
Since the cross-sectional area of this thick member is larger than the cross-sectional area of the rafter only, the drainage member may be thin metal or plastic, and may be lightweight because it is lightweight.
