Abstract
A roof membrane anchoring system is provided comprising upper and lower plates having a water impervious membrane between them. Fasteners secure the lower plate to the roof substrate, and the upper plate is secured against the membrane by a linear fastener penetrating the membrane or by a head and socket engagement without membrane penetration. A plurality of membrane anchoring plates have extending between and secured to them linear elements over the membrane, to limit membrane lift forces.

Roof membrane anchoring system structure for anchoring a water and moisture impervious membrane to a roof substrate comprising:
- (a) upper and lower plates in superposed relationship, said lower plate on and engaging said substrate,
- (b) a membrane between said plates,
- (c) fastener means for holding the said lower plate to the roof substrate comprising at least one linear fastener extending into said substrate and directly securing only said lower plate thereto, and
- (d) means for compressively securing said upper plate against said membrane.
Roof membrane anchoring structure for anchoring a water and moisture impervious membrane to a roof substrate comprising:
- (a) a lower member for placement in engagement with a roof substrate and comprising means outwardly of the central part thereof defining re-entrant groove means,
- (b) a membrane extending over said lower member,
- (c) an upper member on said lower member having at least a portion thereof engaging in at least a portion of said re-entrant groove means, with said membrane in at least a portion of said re-entrant groove means between said portion of said upper member and said means defining said re-entrant groove means of said lower member, and
- (d) means for securing said lower member to said substrate.
A roof membrane anchoring system for anchoring a water and moisture impervious membrane to a roof substrate comprising:
- (a) a plurality of spaced disc means over said membrane,
- (b) means securing each of said disc means to said substrate,
- (c) and linear means extending from and secured to said disc means and overlying said membrane.
Roof membrane anchoring structure for anchoring a water and moisture impervious membrane to a roof substrate comprising:
- (a) a lower member for placement in engagement with a roof substrate,
- (b) a membrane extending over said lower member,
- (c) an upper member on said lower member,
- (d) means for securing said lower member and to said substrate,
- (e) complimentary male and female head and socket means on said upper and lower members for securing said upper member to said lower member with said membrane therebetween,
- (f) said head being axially divided to permit radial contraction thereof and resiliently urged to its non-contracted state.
