A high-strength pullout resistant pintle veneer tie and anchoring system employing the same is disclosed. The high-strength veneer tie utilizes modified 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 veneer tie hereof, when part of the anchoring system, interengages with receptor portions of a wall anchor and is dimensioned to preclude significant veneer tie movement and pullout. The veneer tie is installed within the wall anchor through a swinging motion, fully securing the veneer tie within the anchor.

1. A high-strength wire-formative 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, the outer wythe formed from a plurality of courses with a bed joint of predetermined height between each two adjacent courses, the bed joint being filled with mortar, the veneer tie comprising: an insertion portion for disposition in the bed joint of the outer wythe, the insertion portion comprising two contiguous hook portions;two cavity portions contiguous with the insertion portion; and,a compressively reduced interconnecting portion comprising a first ribbon pintle and a second ribbon pintle, each ribbon pintle contiguous with one of the cavity portions and set opposite the insertion portion,the first ribbon pintle comprising: a first interengaging portion extending at a substantially 90 degree angle from the respective cavity portion; anda securement portion contiguous with the first interengaging portion opposite the cavity portion, the securement portion being disposed at a first angle from the first interengaging portion;the second ribbon pintle comprising: a second interengaging portion extending at a substantially 90 degree angle from the respective cavity portion; andan angled portion contiguous with the second interengaging portion opposite the cavity portion, the angled portion being disposed at a second angle from the second interengaging portion, the second angle being different from the first angle. 2. The high-strength pintle veneer tie of claim 1 wherein the securement portion is disposed at a substantially 90 degree angle from the first interengaging portion. 3. The high-strength pintle veneer tie of claim 2 wherein the angled portion is disposed at a substantially 160 degree angle from the second interengaging portion. 4. The high-strength pintle veneer tie of claim 1 wherein the interconnecting portion is compressively reduced in thickness by up to 75% of the original diameter thereof. 5. The high-strength pintle veneer tie of claim 1, wherein the interconnecting portion is fabricated from 0.172- to 0.312-inch diameter wire and when reduced by one-third has a tension and compression rating at least 130% of the rating for a non-reduced wire formative. 6. The high-strength pintle veneer tie of claim 1, wherein the veneer tie insertion portion further comprises: a compression dimensioned to interlock with a reinforcement wire; and,a reinforcement wire disposed in the compression;whereby upon insertion of the reinforcement wire in the compression, a seismic construct is formed. 7. 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, the outer wythe formed from a plurality of courses with a bed joint of predetermined height between each two adjacent courses, the bed joint being filled with mortar, the anchoring system comprising: a wall anchor adapted to be fixedly attached to the inner wythe and having a free end thereof extending into the cavity, the free end of the wall anchor comprising: one or more receptor portions disposed in the cavity, the one or more receptor portions being openings disposed substantially horizontal; and,a wire-formative veneer tie comprising: an insertion portion for disposition in the bed joint of the outer wythe, the insertion portion comprising two contiguous hook portions;two cavity portions contiguous with the insertion portion; and,a compressively reduced interconnecting portion comprising a first ribbon pintle and a second ribbon pintle, each ribbon pintle contiguous with one of the cavity portions and set opposite the insertion portion,the first ribbon pintle comprising: a first interengaging portion extending at a substantially 90 degree angle from the respective cavity portion; anda securement portion contiguous with the first interengaging portion opposite the cavity portion, the securement portion being disposed at a first angle from the first interengaging portion;the second ribbon pintle comprising: a second interengaging portion extending at a substantially 90 degree angle from the respective cavity portion; andan angled portion contiguous with the second interengaging portion opposite the cavity portion, the angled portion being disposed at a second angle from the second interengaging portion, the second angle being different from the first angle. 8. The high-strength pintle anchoring system of claim 7 wherein the securement portion is disposed at a substantially 90 degree angle from the first interengaging portion. 9. The high-strength pintle anchoring system of claim 8 wherein the angled portion disposed at a substantially 160 degree angle from the second interengaging portion. 10. The high-strength pintle anchoring system of claim 7 wherein the interconnecting portion is compressively reduced in thickness up to 75% of the original diameter thereof. 11. The high-strength pintle anchoring system of claim 10 wherein the interconnecting portion is fabricated from 0.172- to 0.312-inch diameter wire and when reduced by one-third has a tension and compression rating at least 130% of the rating for a non-reduced wire formative. 12. The high-strength pintle anchoring system of claim 10 wherein the one or more receptor portions further comprise two eyelets spaced apart at a predetermined interval and disposed substantially horizontal in the cavity, the first and second interengaging portions each dimensioned to closely fit within one of the openings of the one or more receptor portions; wherein each of the two eyelets is welded closed and has a substantially circular opening therethrough with a predetermined diameter. 13. The high-strength pintle anchoring system of claim 12 wherein the 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 the bed joint, the wall anchor further comprising: a wire formative fixedly adapted to be attached to the reinforcement and having at least two legs for extending into and terminating within the cavity and being affixed to the two eyelets. 14. The high-strength pintle anchoring system of claim 13 wherein a horizontal diameter of the securement portion is dimensioned to be greater than the predetermined diameter of the substantially circular opening and a horizontal diameter of the angled portion is dimensioned to be less than the predetermined diameter of the substantially circular opening; wherein upon insertion of the securement portion within one of the two eyelets the veneer tie is installed by swinging the angled portion into the other eyelet. 15. The high-strength pintle anchoring system of claim 13 wherein a width of each of the first and second interengaging portions is substantially parallel to the longitudinal axes of the legs of the wall anchor. 16. The high-strength pintle anchoring system of claim 10 wherein the one or more receptor portions further comprise a single elongated eyelet adapted to be disposed substantially horizontal in the cavity. 17.
