DESCRIPTION:
BRIEF SUMMARY
The present invention relates to facade and roof cladding for buildings of different kinds, and more specifically to a cladding panel of sheet metal, e.g. surface-treated steel, aluminium, or copper sheeting for facades, walls and roofs, said panel including a middle portion with folded-up side edge portions, of which at least one has an edge portion folded downwards and outwards to form a standing seam for joining one panel to a juxtaposed panel in accordance with the invention.
For cladding building facades and also roofing cladding there are a number of different sheet metal cladding panels on the market, all of which having the disadvantage that the erection of such panels is complicated and time-consuming. This is due to that for their attachment the known cladding panels require special fastening elements in the form of metal strips and fastening clips which are attached to the substructure with the aid of screws or nails for carrying the panel and positionally fixing it laterally. These fastening elements must thus be fastened exactly at the joint between two panels, which requires acurate positional measurement for each fastening element before they can be screwed or nailed. When the panel itself is then lifted into place, the fastening elements are folded over the side edge of the panel by hand, and when the next panel is put in place with its folded seam half gripping over the upstanding side edge of the first panel this element is then folded up around the seam half, and not until this has been done can seaming take place with the aid of a seaming machine. In addition, the known cladding panels which are mutually joined by seaming require an adaption of configuration to joining panels, which takes place by the appropriate parts of the sheet panel being cut away, which is also a time consuming work operation requiring great precision for maintaining closely fitting overlapping and seaming between the panels.
The object of the present invention is therefore to provide a sheet metal cladding panel which does not have the above-mentioned drawbacks, and can be erected simply and quickly and which does not require for its erection any special fastening elements such as fastening strips or clips, but only conventional fastening elements such as screws or nails, neither does it require any adaption of configuration to joining cladding panels, which means that cladding panels in accordance with the present invention can be supplied ready-formed from the factory.
This object is achieved by the cladding panel in accordance with the present invention having been given the distinguishing features disclosed in the accompanying claims, and in principles by the side edge of the panel provided with the folded-over half seam being formed by first folding over the edge portion, the half seam thus being of double thickness, to form a fastening flange projecting from the lower part of the upstanding side portion such as to provide for fastening the panel to a substructure. To advantage, this fastening flange can be arranged in line with the middle portion of the panel.
The invention will now be described in more detail and with reference to the accompanying drawings, on which
