Abstract:
A method for controlling uplift on a roof with a plurality of clamps and transverse bars, the roof being formed from a substructure, a plurality of roof panels and seams defining an interconnection between adjacent said roof panels, each of said clamps comprising a base which supports a channel, said channel supported in a transverse orientation to said seams, said channel located above a top edge of said seams, each of said transverse bars being elongated and having first and second ends, and being supported in said channel, wherein each transverse bar bridges from one seam to an adjoining seam, said method comprising the steps of:positioning a first of said clamps on a first of said seams at a first location to receive a portion of said first seam, said first seam interconnecting first and second roof panels; inserting at least a first of said transverse bars into said channel of said first clamp; securing said first clamp onto said first seam, and securing a second clamp onto a second and adjacent seam; inserting a portion of said first transverse bar in said second clamp in a channel of said second clamp; fastening at a point on said transverse bar between said first and second seams a downward depending anti-lift brace rigidly mounted so as not to move, said brace functioning to prevent an uplift of a roof panel located between said first and second seams and to prevent a rupture of said roof panel; and wherein a foot means depends from the anti-lift brace, said foot means functioning to provide during a wind uplift a surface contact with the roof, said surface contact having a contact area greater than a contact area of a bottom edge of the anti-lift brace.
