  • C-clamp body and method of manufacture thereof for securing a flexible building wall panel under tension
    Patent number: 12601194
    Abstract: A clamp apparatus is used for securing one end of a flexible sheet spanning under tension across a building opening relative to a perimeter beam along the edge of the building opening. The clamp apparatus has a C-shaped channel body having (i) a first flange with a threaded bore therein to receive a bolt defining a first clamping jaw and (ii) a second flange defining an opposing second clamping jaw, whereby the clamp apparatus clamps a perimeter mounted flange of the flexible sheet onto a beam flange of the perimeter beam. C-shaped stiffener plates are mounted externally on the channel body, spaced apart from one another along the length of the channel body in perpendicular relation to the length to reinforce the clamp such that the clamp is able to withstand high wind forces acting on the tensioned sheet.
