A high-strength pullout resistant pintle and anchoring system employing the same is disclosed. The modified veneer tie utilizes ribbon pintles formed from 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 outer wythe. The ribbon pintles hereof, when part of the anchoring system, interengage with receptor portions of a wall anchor and are dimensioned to preclude significant lateral, vertical and horizontal movement.

1. A high-strength pintle veneer tie for use with an anchoring system in a wall having an inner wythe and an outer wythe in a spaced apart relationship the one with the other and having a cavity therebetween, said outer wythe formed from a plurality of courses with a bed joint of predetermined height between each two adjacent courses, said bed joint being filled with mortar, said veneer tie comprising: an insertion portion for disposition in said bed joint of said outer wythe, said insertion portion comprising two contiguous hook portions;two cavity portions contiguous with said hook portions; and,two ribbon pintles contiguous with said cavity portions and set opposite said hook portions, wherein said ribbon pintles are compressively reduced, each of said ribbon pintles having a thickness and a width greater than the thickness, the width being substantially parallel to the cavity portions, said ribbon pintles each further comprising: an interengaging portion for disposition within said anchoring system, said interengaging portion rounded at a substantially 90 degree angle; and,a securement portion contiguous with said interengaging portion opposite said cavity portion, said securement portion disposed at a substantially 90 degree angle from said interengaging portion;whereby upon insertion within said anchoring system, said veneer tie restricts lateral, vertical and horizontal movement. 2. A high-strength pintle veneer tie as described in claim 1 wherein said ribbon pintles are compressively reduced in thickness by up to 75% of an original diameter thereof. 3. A high-strength pintle anchoring system as described in claim 2, wherein said ribbon pintles are fabricated from 0.172- to 0.312-inch diameter wire and when reduced by one-third have a tension and compression rating at least 130% of the rating for a non-reduced pintle. 4. A high-strength pintle veneer tie as described in claim 2 wherein said insertion portion is fabricated from 0.172- to 0.312-inch diameter wire and wherein said wire formative is compressively reduced to a height of between 0.162 to 0.187 inches. 5. A high-strength pintle veneer tie as described in claim 4 wherein said veneer tie insertion portion further comprises one or more housings each having a clamping jaw for receiving a reinforcement wire whereby, upon installation of said veneer tie in said anchoring system with said reinforcing wire in said outer wythe, said system provides a high degree of seismic protection. 6. A high-strength pintle anchoring system for use in a wall having an inner wythe and an outer wythe in a spaced apart relationship the one with the other and having a cavity therebetween, said outer wythe formed from a plurality of courses with a bed joint of predetermined height between each two adjacent courses, said bed joint being filled with mortar, said system comprising: a wall anchor for fixedly attaching to said inner wythe so that a free end thereof extends into said cavity, said free end of said wall anchor comprising: one or more receptor portions for disposing in said cavity, said one or more receptor portions being openings adapted to be disposed substantially horizontal in said cavity; and,a wire-formative veneer tie comprising: an insertion portion for disposition in said bed joint of said outer wythe, said insertion portion comprising two contiguous hook portions;two cavity portions contiguous with said hook portions; and,two ribbon pintles contiguous with said cavity portions and set opposite said hook portions, wherein said ribbon pintles are compressively reduced, each of said ribbon pintles having a thickness and a width greater than the thickness, the width being substantially parallel to the cavity portions, said ribbon pintles each further comprising: an interengaging portion for disposition within said anchoring system, said interengaging portion rounded at a substantially 90 degree angle; and,a securement portion contiguous with said interengaging portion opposite said cavity portion, said securement portion disposed at a substantially 90 degree angle from said interengaging portion;whereby upon insertion within said anchoring system, said veneer tie restricts lateral, vertical and horizontal movement. 7. A high-strength pintle anchoring system as described in claim 6 wherein said one or more receptor portions further comprise two eyelets spaced apart at a predetermined interval and disposed substantially horizontally in said cavity. 8. A high-strength pintle anchoring system as described in claim 7 wherein each of said ribbon pintles is dimensioned to closely fit one of said openings of said one or more receptor portions; and, wherein each of said two eyelets is welded closed and has a substantially circular opening therethrough with a predetermined diameter. 9. A high-strength pintle anchoring system as described in claim 8 wherein said inner wythe is formed from successive courses of masonry block with a bed joint of predetermined height between each two adjacent courses and having a reinforcement ladder or truss in said bed joint, said wall anchor further comprising: a wire formative fixedly attached to said reinforcement having at least two legs extending into and terminating within said cavity. 10. A high-strength pintle anchoring system as described in claim 9 wherein the length of each said securement portion is dimensioned to be greater than the diameter of each said opening of said one or more receptor portions. 11. A high-strength pintle anchoring system as described in claim 10 wherein a width of said ribbon pintles is in a close fitting functional relationship with said diameter of said eyelet. 12. A high-strength pintle anchoring system as described in claim 11 wherein the widths of said ribbon pintles are substantially parallel to the longitudinal axes of said legs of said wall anchor; and, wherein said ribbon pintles are compressively reduced in thickness up to 75% of an original diameter thereof. 13. A high-strength pintle anchoring system as described in claim 6 wherein said inner wythe is a dry wall structure having wallboard panels mounted on columns or framing members, said wall anchor further comprising: a surface-mounted sheetmetal bracket fixedly attached to said columns of said inner wythe, said sheetmetal bracket being L-shaped and having a mounting portion and an extending portion for extending substantially horizontally into said cavity, said extending portion with said one or more receptor portions therethrough. 14. A high-strength pintle anchoring system as described in claim 13 wherein said one or more receptors further comprise an elongated aperture. 15. A high-strength pintle anchoring system as described in claim 14 wherein said elongated aperture is shaped substantially similar to the cross section of said ribbon pintles; and wherein the width of said ribbon pintles is in a close fitting functional relationship with the opening of said aperture and the widths of said ribbon pintles are substantially normal to said wallboard panels. 16. A high-strength pintle anchoring system as described in claim 15 wherein the distance between each said securement portion is dimensioned to be greater than the diameter of each said opening of said one or more receptor portions. 17. A high-strength pintle anchoring system as described in claim 16, wherein said anchoring system further comprises: a reinforcement wire disposed in said bed joint; and, wherein said veneer tie insertion portion further comprises:one or more housings each having a clamping jaw for receiving said reinforcement wire; whereby, upon installation of said anchoring system with an interconnected reinforcing wire in said outer wythe, said system provides a high degree of seismic protection. 18. A high-strength pintle anchoring system as described in claim 17 wherein said ribbon pintles are compressively reduced in thickness up to 75% of an original diameter thereof. 19. A high-strength pintle anchoring system as described in claim 18, wherein said ribbon pintles are fabricated from 0.172- to 0.312-inch diameter wire and when reduced by one-third have a tension and compression rating at least 130% of the rating for a non-reduced pintle. 20. A high strength pintle veneer tie as described in claim 1 wherein the cavity portions are free of compressive reduction.
