Abstract
A covering material having corrugations and having on one of its surfaces, hollowed areas (3) in the convex part (10) of the corrugations (2) for laying tiles.
Claims12
A corrugated roof support material, comprising a roofing sheet with parallel corrugations of peaks and valleys, said peaks having plural hollow means for receiving roofing tile tenons therein, said hollow means being aligned across said peaks substantially perpendicular to the corrugations, and wherein a ratio of an amplitude of the corrugations to a pitch of the corrugations is from 1:2 to 1:1.
A corrugated roofing material, comprising a roofing sheet with parallel corrugations of peaks and valleys, said peaks having plural hollowed areas therein which are aligned across said peaks substantially perpendicular to the corrugations and which are spaced apart by a center-to-center distance greater than a distance encompassed by at least five of said peaks measured in a direction perpendicular to the corrugations, wherein each of said hollowed areas has a planar bottom and planar sides which slope away from a center thereof, and wherein said peaks are planar and said valleys are rounded so that said planar sides are trapezoid-shaped.
A roof comprising:
- plural overlapping tiles, each with a tenon on a bottom thereof;
- a corrugated roofing sheet for supporting said tiles and having parallel corrugations of peaks and valleys, said peaks having plural hollowed areas therein in which said tenons rest, said hollowed areas being aligned across said peaks substantially perpendicular to the corrugations and spaced apart in a direction parallel to the corrugations by a distance that is the same as a distance between said tenons of adjacent ones of said overlapping tiles, and wherein a ratio of an amplitude of the corrugations to a pitch of the corrugations is from 1:2 to 1:1.
