Abstract:
1. In an anchoring system for fastening an elastomeric membrane to a roof, said system including: (a) an anchoring plate having a top planar surface and a pair of spaced apart, raised sidewalls each with an outside edge over which the membrane may be laid, each sidewall having a retaining lip that extends inwardly from, and substantially parallel to, said top planar surface for the retention of a spacing insert, and at least one aperture in said top planar surface for securing said anchoring plate to said roof; (b) a spacing insert with outer edges arranged for inserting into said anchoring plate; a planar bottom of said spacing insert having a pair of vertical flanges that divide said planar bottom into an interior region between said flanges, and two exterior regions, each flange having an upper retaining lip that extends over said retaining lip of the anchoring plate when assembled, the inwardly extending portions of said lips, interior faces of said flanges and the interior region of said planar bottom defining a cavity into which an insert wedge may be slid for securely interlocking said anchoring system and outwardly extending portions of said lips, exterior faces of said flanges, an upper retaining lip, and a lower retaining lip defining a pair of C-shaped notches that snappingly engage the retaining lips of said anchoring plate after said membrane has been laid thereover; (c) the insert wedge having a top and a bottom surface and a raised lip along one edge that facilitates insertion of said insert wedge in said spacing insert cavity; and (d) means for securely fastening said anchoring plate to said roof, wherein each retaining lip on the spacing insert includes a plurality of longitudinally extending gripper ridges which allow the elastomeric membrane to release and recover from the stretching caused by sliding or placing insert into the anchor plate.
