Patent ID: 6889478

Claim:
An assembly in which adjacent panels are supported by underlying support structure in overlapping edge relationship to form a standing seam assembly with a sidelap shear capacity resistant to side slipping when subjected to applied forces, the assembly comprising: a first panel having a female sidelap portion comprising a female cavity and a downwardly angled leg with hook portion adjacent said cavity; a second panel comprising a male sidelap portion having a tang portion extending from a fifth leg portion lockingly disposed in the female cavity of the first panel, said downwardly angled leg with hook portion in conjunction with said tang portion providing a standing seam between the first and second panels formed by pressing said downwardly angled leg with hook portion into mating contact with said tang portion and folding said mated downwardly angled leg with hook and tang portions into adjacency with said fifth leg portion, the female sidelap portion further forming a first leg portion, said assembly with the sidelap shear capacity formed by downwardly forming the standing seam to create an acute angle with respect to said first leg portion; and means for increasing the sidelap shear capacity of the standing seam assembly.
