<p>Provided is a piece of fitting type folded plate roofing wherein there are formed a plurality of crest sections that include crest sections not having seam joint fitting sections; wherein furthermore, mutual connecting strength due to inside seam joints and outside seam joints is improved; wherein thereby there is excellence in wind pressure withstanding strength with respect to wind blow-up pressure; wherein moreover, neither loosening nor disconnection occurs in seam joint fitting sections due to pressing force caused by a worker's treading-down or the like; and wherein thus high seam joint effect is achieved. Said fitting type folded plate roofing is such that seam-joined crest sections and one or more non- seam-joined crest sections are continuously provided, with bottom sections therebetween; that furthermore, either an inside seam joint fitting section or an outside seam joint fitting section is provided on top of each seam-joined crest section; that adjacent rectangular metal plates are connected to each other, with the inside and outside seam joint fitting sections therebetween; that the outside seam joint fitting section has an approximately mushroom-shaped cross section; and that the inside seam joint fitting section has an approximately umbrella-shaped cross section.</p> |
