Abstract

The roof or facade cladding comprises panel-shaped construction elements (1) arranged in a scale-type pattern, and each construction element (1) comprises at least a panel part (2), a frame and at least one retaining element (6). Each construction element (1) is secured by the at least one retaining element (6) on an essentially horizontally disposed support element (27). Each retaining element (6) is disposed on the respective construction element (1) adjacent to a bottom, essentially horizontally oriented edge (5) of the construction element (1) and the point (20) of the retaining element (6) contacting the support element (27) lies closer to this bottom edge (5) than the top edge (11) of the construction element (1). Each construction element is protected from mechanical damage all the way round at the edges the frame. The retaining elements (6) primarily secure the bottom edge of the construction element (1), whilst the top part of the construction elements and their frames lie underneath the construction element disposed in the next row above and is fixed thereby.

Claims

1. Roof or facade cladding comprising panel-shaped construction elements (1) disposed in a scale-type pattern, and each construction element (1) has at least one retaining element (6) disposed on the internal face (16) of the construction element (1) directed towards the building, and each construction element (1) is secured by the at least one retaining element (6) on an essentially horizontally disposed support element (27) whereby a slot (20) provided in the retaining element (6) opening at the bottom extends round the support element (27) in a clamping arrangement, and the at least one retaining element (6) is disposed on the construction element (1) adjacent to the bottom, essentially horizontally oriented edge (5) of the construction elements (1) and the slot (20) of the retaining element (6) extending round the support element (27) lies closer to this bottom edge (5) than the top front face (12) of the construction element (1), wherein the construction element (1) comprises at least a panel part (2) and a frame (3) at least partially surrounding the panel part (2) and the distance of the slot (20) from the internal face (16) of the construction element corresponds to at least the thickness of the construction element (1) at its top front face (12).

2. Roof or facade cladding as claimed in claim 1, wherein the retaining element (6) is disposed on the frame (3).

3. Roof or facade cladding as claimed in claim 2, wherein the retaining element (6) is integrally joined to the frame (3).

4. Roof or facade cladding as claimed in claim 1, wherein the frame (3) is made from plastic and is preferably manufactured by an injection moulding process.

5. Roof or facade cladding as claimed in claim 4, wherein the panel part (2) is joined to the frame (3) by injecting it round the panel part (2).

6. Roof or facade cladding as claimed in claim 1, wherein the support element (27) is provided in the form of a profiled bar secured to a sub-structure (4), which has upwardly pointing (arrow 18) legs (21) spaced at a distance apart from the sub-structure (4).

7. Roof or facade cladding as claimed in claim 1, wherein in the overlap region of the bottom edge (5) of the construction element (1), the face directed towards the support element (27) and/or the top edge (11) of the construction element (1) on the face directed away from the support element (27) is roughened or provided with ridges and/or ribs.

8. Roof or facade cladding as claimed in claim 1, wherein the side edges (7, 8) of every construction element (1) are provided with elements (30, 31) which locate in a sealing engagement with co-operating elements (31, 30) of the horizontally adjacent construction element.

9. Roof or facade cladding as claimed in claim 1, wherein the frame (3) at the bottom edge (5) does not project beyond the panel part (2) perpendicular to the plane of the panel part (2).

10. Roof or facade cladding as claimed in claim 1, wherein the construction element (1) contains a flat element (22) of inflammable material on its rear face.

11. Roof or facade cladding as claimed in claim 1, wherein at least a part of the panel part (2) is designed as a photovoltaic element or contains one.

12. Roof or facade cladding as claimed in claim 11, wherein the frame (3) at the top edge (11) of the construction element (1) is sufficiently wide and the distance between the support elements (27) such that the bottom edge (5) of the adjacent construction element (1) above does not extend across the photovoltaic element or does so only by a maximum of 5% of the vertical length of the photovoltaic element.

13. Roof or facade cladding as claimed in claim 11, wherein at least one electric terminal point (19) is provided in the top edge (11) of the construction element, which is preferably accessible from the front face (12) of the top edge (11).

14. Roof or facade cladding as claimed in claim 11, wherein the photovoltaic elements are disposed on the internal face of the panel part (2) and the frame (3) is designed so that it forms the waterproof encapsulation of the photovoltaic elements, and the external face of the panel part (2) is waterproof.
