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. An anchoring system for use in a wall having a backup wall and a facing wall in a spaced apart relationship forming a cavity therebetween, the backup wall formed from a plurality of successive courses of masonry blocks with a bed joint between each two adjacent courses, the anchoring system comprising: a wire formative wall reinforcement for insertion in the bed joint and having attachment sites at intervals therealong, the attachment sites each comprising an indentation swaged into the wire formative wall reinforcement;at least one wall anchor connected to the wire formative wall reinforcement, the at least one wall anchor comprising a wire formative having a diameter and having at least two attachment portions connected to the attachment sites, the at least one wall anchor further comprising a ribbon loop portion contiguous with the at least two attachment portions for disposition in the cavity, the ribbon loop portion being compressively reduced. 2. The anchoring system as set forth in claim 1 wherein an interconnection of each attachment portion of the at least one wall anchor in the indentation forming the attachment site defines a juncture, the juncture having an overall height not greater than the diameter of the wire formative of the at least one wall anchor. 3. The anchoring system as set forth in claim 1 further comprising a veneer tie having an interengaging end portion for interengagement with the ribbon loop portion and, upon installation, configured for insertion in the facing wall. 4. The anchoring system according to claim 3, wherein the ribbon loop portion is fabricated from a wire having a diameter of up to 0.375-inch and when compressively reduced in thickness up to 75% of the original diameter thereof has a tension and compression rating of at least 130% of the rating for a non-reduced wire formative. 5. The anchoring system according to claim 4, wherein the ribbon loop portion further comprises an eyelet vertically disposed in the cavity and welded closed forming an oval opening therethrough with a predetermined diameter in a functional relationship with the diameter of the veneer tie interengaging end portion. 6. The anchoring system according to claim 5, and wherein a major cross-sectional axis of the ribbon loop portion is generally parallel to the wire formative wall reinforcement. 7. The anchoring system according to claim 6, wherein the facing wall is formed from a plurality of successive courses of bricks with a bed joint between adjacent courses; and wherein, the veneer tie is a box tie having an opening for threadingly engaging the ribbon loop portion, the opening configured for insertion in the bed joint of the facing wall. 8. An anchoring system for use in a wall having a backup wall and a facing wall in a spaced apart relationship forming a cavity therebetween, the backup wall formed from a plurality of successive courses of masonry blocks with a bed joint between each two adjacent courses, the anchoring system comprising: a wire formative wall reinforcement for insertion in the bed joint and having attachment sites at intervals therealong, the attachment sites each comprising an indentation swaged into the wire formative wall reinforcement;at least one wall anchor connected to the wire formative wall reinforcement, the at least one wall anchor comprising a wire formative having a diameter and having at least two attachment portions connected to the attachment sites, and leg portions extending toward the cavity, an interconnection of each of the at least two attachment portions of the at least one wall anchor in the indentation forming the attachment site defines a juncture, the juncture having an overall height not greater than the diameter of the wire formative of the wall anchor, the at least one wall anchor further comprising a ribbon loop portion contiguous with the at least two attachment portions for disposition in the cavity, the ribbon loop portion having a thickness and a width, the width being greater than the thickness, and wherein the width is generally parallel to the leg portions of the at least one wall anchor. 9. The anchoring system as set forth in claim 8 further comprising a veneer tie configured for connection to the wall anchor and, upon installation, configured for insertion in the facing wall. 10. An anchoring system for use in a wall having a backup wall and a facing wall in a spaced apart relationship forming a cavity therebetween, the backup wall formed from a plurality of successive courses of masonry blocks with a bed joint between each two adjacent courses, the anchoring system comprising: a wire formative wall reinforcement for insertion in the bed joint and having attachment sites at intervals therealong;at least one wall anchor connected to the wire formative wall reinforcement, the at least one wall anchor comprising a wire formative having a diameter and having at least two attachment portions connected to the attachment sites, the at least one wall anchor further comprising a ribbon loop portion contiguous with the at least two attachment portions for disposition in the cavity, the ribbon loop portion being compressively reduced. 11. The anchoring system according to claim 10, wherein the ribbon loop portion is fabricated from a wire having a diameter of up to 0.375-inch and when compressively reduced in thickness up to 75% of the original diameter thereof has a tension and compression rating of at least 130% of the rating for a non-reduced wire formative. 12. The anchoring system according to claim 10, further comprising a veneer tie adapted for connection to the wall anchor, and wherein the ribbon loop portion further comprises an eyelet vertically disposed in the cavity and welded closed forming an oval opening therethrough with a predetermined diameter in a functional relationship with the diameter of the veneer tie interengaging end portion. 13. The anchoring system according to claim 12, and wherein a major cross-sectional axis of the ribbon loop portion is generally parallel to the wire formative wall reinforcement. 14. The anchoring system according to claim 13, wherein the facing wall is formed from a plurality of successive courses of bricks with a bed joint between adjacent courses; and wherein, the veneer tie is a box tie having an opening for threadingly engaging the ribbon loop portion, the opening configured for insertion in the bed joint of the facing wall.
