A high-strength ribbon loop anchor and cavity wall anchoring system employing the same is disclosed. The ribbon loop anchor is a wire formative construct that is cold-worked with the resultant body having substantially semicircular edges and flat surfaces therebetween. The edges are aligned to receive compressive forces transmitted from the facing wall. The ribbon loops hereof, when part of the anchoring system, interengage with the veneer tie and are dimensioned to preclude significant movement lateral with or normal to the inner wythe.

1. A ribbon loop anchor and reinforcement device for use in a wall formed from a backup wall and a facing wall in a spaced apart relationship having a cavity therebetween, the backup wall being formed from a plurality of successive courses of masonry blocks with a mortar-filled bed joint of predetermined height between each two adjacent courses, the anchor and reinforcement device comprising: a wire formative wall reinforcement configured for embedment within the bed joint, the wire formative in turn, comprising; a pair of side wires disposed parallel to one another;one or more intermediate wires affixed to the interior sides of the side wires maintaining the parallelism thereof in a truss or ladder configuration;at least one wire formative wall anchor fusibly attached at one end thereof to the wall reinforcement, and, upon installation, extending into the cavity, the wall anchor comprising, in turn: one or more leg portions extending toward the cavity;one or more ribbon cavity portions contiguous with the one or more leg portions; and,a ribbon loop contiguous with each of the one or more ribbon cavity portions opposite the one or more leg portions, the ribbon loop being compressively reduced and configured to interengage a veneer tie for insertion within the facing wall. 2. The device according to claim 1, wherein the one or more ribbon cavity portions are compressively reduced. 3. The device according to claim 2, wherein the one or more leg portions are compressively reduced. 4. The device according to claim 2, wherein the wall anchor further comprises a rear leg fusibly attached to and connecting the one or more leg portions. 5. The device according to claim 2, wherein the device further comprises a wire formative veneer tie having an interconnecting portion; wherein the ribbon loop forms an eyelet disposed substantially vertical in the cavity, the eyelet is welded closed and has a substantially oval opening therethrough with a predetermined diameter in a close fitting functional relationship with the diameter of the veneer tie interconnecting portion. 6. The device according to claim 5, wherein the ribbon loop and the one or more ribbon cavity portions are compressively reduced in thickness up to 75% of the original diameter thereof. 7. The device according to claim 6, wherein the ribbon loop and the one or more ribbon cavity portions are fabricated from a wire having a diameter of up to 0.375-inch and when reduced by one-third have a tension and compression rating at least 130% of the rating for a non-reduced wire. 8. The device according to claim 6, wherein the ribbon loop and the one or more ribbon cavity portions are fabricated from 0.250-inch diameter wire and wherein the wire is compressively reduced to a height of 0.168 inches and has a tension and compression rating at least 200% greater than the rating for a non-reduced wire. 9. The device according to claim 6, wherein the ribbon loop and the one or more ribbon cavity portions are fabricated from 0.187-inch diameter wire and wherein the wire is compressively reduced to a height of 0.095 inches and has a tension and compression rating at least 100% greater than the rating for a non-reduced wire. 10. The device according to claim 6, wherein the ribbon loop has a thickness and a width greater than the thickness, wherein the width of the ribbon loop is substantially parallel to the one or more leg portions. 11. A high-strength ribbon loop anchoring system for use in a cavity wall formed from a backup wall and a facing wall in a spaced apart relationship with a vertical surface of the backup wall forming one side of a cavity therebetween, the backup wall formed from a plurality of successive courses of masonry block with a bed joint of predetermined height between each two adjacent courses, the anchoring system comprising, in combination: a wall reinforcement with an upper surface in one plane and a lower surface in a plane substantially parallel thereto, the wall reinforcement adapted for mounting in the bed joint of the backup wall;at least one wire formative wall anchor fusibly attached at an attachment end thereof to the wall reinforcement, and, upon installation in the bed joint of the backup wall, extending between the plane of the upper surface and the plane of the lower surface to the vertical surface of the backup wall; the wall anchor, in turn, comprising: one or more extended leg portions for spanning the cavity, each extended leg portion having a free end contiguous therewith, opposite the attachment end and compressively reduced in thickness up to 75% of the original diameter thereof, the free end having a ribbon loop formed therefrom and extending to the attachment end, the ribbon loop being compressively reduced, the ribbon loop configured to interengage a veneer tie; and,a wire-formative veneer tie having an insertion end portion for disposition in the facing wall and an interengaging end portion for interengagement with the ribbon loop. 12. The anchoring system according to claim 11, wherein the wall anchor has two extended leg portions spaced apart at a predetermined interval, each extended leg portion having a ribbon loop, each ribbon loop further comprising an eyelet. 13. The anchoring system according to claim 12, wherein the ribbon loop eyelet is disposed substantially vertical in the cavity and welded closed forming a substantially oval opening therethrough with a predetermined diameter in a close fitting functional relationship with the diameter of the veneer tie interengaging end portion. 14. The anchoring system according to claim 13, wherein the ribbon loop has a thickness and a width greater than the thickness, wherein the width of the ribbon loop is substantially parallel to the extended leg portions. 15. The anchoring system according to claim 14, wherein the free end is fabricated from a wire having a diameter of up to 0.375-inch and when reduced by one-third has a tension and compression rating of at least 130% of the rating for a non-reduced wire formative. 16. The anchoring system according to claim 15, wherein the wall anchor is a single construct. 17. The anchoring system according to claim 15, wherein the wall anchor further comprises a rear leg fusibly attached to and connecting the two extended leg portions.
