Membrane plate

摘要

An improved membrane plate for attaching a membrane to a roof is disclosed. The improved membrane plate includes a plate body portion having a bottom surface for disposing the bottom surface against the membrane and an opening to permit a fastening device to pass therethrough for securing the membrane plate and the membrane to the roof. A plurality of spaced apart lances joined to said plate body portion by a hinged lance edge and extending downwardly from the plate body portion wherein the spaced apart lances are disposed upon the plate body portion to define an oval shape having a longitudinal oval axis. The hinged edges are aligned parallel to the longitudinal oval axis. The membrane plate is subjected to a shear force when attached to the roof and is disposed such that the longitudinal oval axis of the membrane plate is perpendicular to the shear force. The lances include longitudinal lance edges extending from the plate body to a lance tip and the longitudinal lance edges of all of the lances are aligned perpendicular to the shear force. The plate body portion can be an oval-shaped region. An annular ridge is formed to define a plurality of recesses and a lance of the plurality of lances is disposed within each of the recesses. A central hub region defined by an annular ridge is provided wherein the opening passes through the central hub region.
