Abstract
A stress plate or seam plate for use in connection with securing membrane sheets to underlying roofing decking substructure comprises a circular disk having a central aperture for receiving a screw fastener. A plurality of concentric ribs are defined between the central aperture and the peripheral edge of the plate for providing reinforcing and bending or flexibility characteristics to the stress plate or seam plate, and in accordance with the principles and teachings of the present invention, a plurality of circumferentially spaced, downwardly extending projections having substantially V-shaped cross-sectional configurations are provided upon the underside of the seam or stress plate so as to engage the membrane sheets and retain the same at their desired locations upon the underlying roofing deck substructural assembly. Contrary to conventional stress plates having sharp-pointed prongs or tangs, the projections of the present invention have substantially rounded or radiused apices so as not to puncture or rupture the membrane sheets.
