Abstract
A roof cladding panel is profiled in its longitudinal direction and stepped in its transverse direction and comprises two straight side edges (4, 5) which are connectable to adjacent panels, a lower edge (2) which is generally wave-shaped and connectable to an adjacent panel, and an upper edge (3) which preferably is straight and connectable to an adjacent panel. Two diagonally opposite corners (8, 9) of the panel are obliquely cut, and an upper cut corner of one panel is adapted to be matchingly assembled with a lower cut corner of another panel in a four-corner joint including also non-cut corners of a third and a fourth roof cladding panel.
Claims26
A roof cladding element comprising:
- a rectangular panel or plate comprising a cross-sectional profile extending in a longitudinal direction, two longitudinally-extending straight side edge portions, a transversely-extending lower edge portion varying longitudinally in a generally wave shape, a transversely-extending upper edge portion, a transversely-extending step formed in the panel or plate, and four corners;
- a first upper corner and a first lower corner diagonally opposite the first upper corner, the upper corner and the lower corner being obliquely cut at matching angles;
- and
- a second upper corner and a second lower corner diagonally opposite the second upper corner being non-cut.

A roof cladding element comprising:
- a rectangular panel or plate of sheet metal comprising a cross-sectional profile extending in a longitudinal direction, two longitudinally-extending straight side edge portions, a transversely-extending lower edge portion varying longitudinally in a generally wave shape, a transversely-extending upper edge portion, a transversely-extending step formed in the panel or plate, the transversely-extending step having the generally wave shape of the lower edge portion, and four corners;

1 more element
A roof cladding system comprising:
- a first roof cladding element, a second roof cladding element, a third roof cladding element, and a fourth roof cladding element, each roof cladding element comprising:
- a rectangular panel or plate comprising a cross-sectional profile extending in a longitudinal direction, two longitudinally-extending straight side edge portions, a transversely-extending lower edge portion varying longitudinally in a generally wave shape, a transversely-extending upper edge portion, a transversely-extending step formed in the panel or plate, and four corners;
- a first upper corner and a first lower corner diagonally opposite the first upper corner, the upper corner and the lower corner being obliquely cut at matching angles;
- and
- a second upper corner and a second lower corner diagonally opposite the second upper corner being non-cut;
- the roof cladding elements assemblable to form a four-corner joint in which the obliquely cut first upper corner of the third element abuts the obliquely cut first lower corner of the second element, the abutting corners forming a middle layer between the second upper non-cut corner of the first element and the second lower non-cut corner of the fourth element.
3 more elements
A method of assembling roof cladding elements, comprising:
- providing at least four roof cladding elements, each roof cladding element comprising:
- a rectangular panel or plate comprising a cross-sectional profile extending in a longitudinal direction, two longitudinally-extending straight side edge portions, a transversely-extending lower edge portion varying longitudinally in a generally wave shape, a transversely-extending upper edge portion, a transversely-extending step formed in the panel or plate, and four corners;
- a first upper corner and a first lower corner diagonally opposite the first upper corner, the upper corner and the lower corner being obliquely cut at matching angles;
- and
- a second upper corner and a second lower corner diagonally opposite the second upper corner being non-cut;
- attaching a first element to a roof supporting structure;
- attaching a second element to the roof supporting structure with the lower edge portion of the second element overlapping the upper edge portion of the first element;
- attaching a third element to the roof supporting structure overlapping the first element along adjacent side edges, the obliquely cut lower corner of the second element abutting the obliquely cut upper corner of the third element;
- and
- attaching a fourth element to the roof supporting structure, the non-cut lower corner overlapping the abutting obliquely cut lower corner and obliquely cut upper corner, and the lower edge portion of the fourth element overlapping the upper edge portion of the third element, and overlapping the second element along adjacent side edges.
