Abstract (en)
[origin: WO2010028773A1] In roof covering systems using zinc or zinc-alloy trays with standing-seam crimping, the use of tabs secured by two screws is well known. The invention particularly relates to a metal fastening tab for securing a standing-seam tray on a wood or wood-derivative carrier, which comprises a first surface (1) with a perforation (2) for receiving a screw for attachment onto the carrier, a second surface (3) generally perpendicular to said first surface and including a hook (4) for engaging with the ridge of the tray to be secured, the two surfaces defining an edge (5), characterised in that the first surface includes a single perforation (2) for receiving a single screw, and in that the centre (6) of said perforation (2) is not included in the mediator (7) of the edge (5) in order to reduce the force applied on the tab and on the tray by the torque induced when tightening said screw. Such a tab, with a single large-diameter screw, is easier and quicker to place than traditional tabs. The tab is specially designed to limit its own torsion and to avoid any buckling of the tray to be secured when tightening the single screw.
