A membrane anchor system including a body made of resilient metal comprising a central region with an opening therein, a downwardly sloping region and a peripheral region outwardly of the downwardly sloping region; the downwardly sloping region has radially extending upwardly convex regions therein

A membrane anchor system including a body made of resilient metal comprising a central region with an opening therein, a downwardly sloping region and a peripheral region outwardly of the downwardly sloping region; the downwardly sloping region has radially extending upwardly convex regions therein to resist upward flexure. A linear fastener extends through the body and through the membrane, and mastic is placed between the body and the membrane.

In a membrane anchor system in which a roof substrate is covered with a membrane or water impervious material anchored by linear fasteners which penetrate the membrane and are secured to underlying roof structure, a resilient thin disc-like body for engaging said membrane having upper and lower surfaces, said body having an unstressed state and being deformable to a stressed state under load imposed by the linear fastener, and comprising: (a) a central, substantially planar region, (b) an opening through said body in said central region for a linear fastener, (c) means defining a downwardly facing cavity above said membrane outwardly of and surrounding said central region and said opening, said means in part extending above central region thereby defining in the upper surface a recess above said central region, (d) means defining a groove in surrounding relationship to said cavity defining means, (e) an intermediate region extending outwardly of said groove and having an outer boundary, a peripherally extending flexure zone in said body at said outer boundary, (f) an outer engaging region in surrounding relation to said flexure zone and located at a level below the bottom surface of said groove in the unstressed state of said body, said outer engaging region engaging said membrane in the stressed state of said body, (g) said intermediate region defining therebeneath a mastic overflow cavity outwardly of said groove, and having a bending zone at its inner boundary. (h) said downwardly sloping region having therein radially extending, upwardly convex regions.
