A high-strength disengagement prevention pintle veneer tie and anchoring system employing the same is disclosed. The high-strength veneer tie utilizes modified compressed wire formatives 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 wall anchor and is dimensioned to preclude veneer tie movement and pullout through the use of the U-shaped securement portions. The veneer tie is installed within the wall anchor through a swinging motion, in either an over and through or under and through the anchor installation, fully securing the veneer tie within the anchor and providing flexibility during installation.

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 a spaced apart 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;two cavity portions contiguous with the insertion portion, the cavity portions being interconnected with one another; and, an 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 and the second ribbon pintle each further comprising:an elbow portion for interconnection with the anchoring system; and,a U-shaped securement portion having a first end contiguous with the elbow portion and opposite the cavity portion, the U-shaped securement portion having a second end and being free from direct connection to the respective cavity portion, the second end spaced apart from the elbow portion, the U-shaped securement portion being compressively reduced such that the U-shaped securement portion has a thickness and a width greater than the thickness,whereby upon insertion of the veneer tie within the anchoring system, the interconnecting portion prevents the veneer tie from disengaging from the anchoring system, while allowing for restricted vertical adjustment. 2. The high-strength pintle veneer tie of claim 1 wherein the interconnecting portion is compressively reduced. 3. The high-strength pintle veneer tie of claim 2 wherein the interconnecting portion is compressively reduced in thickness by up to 75% of the original diameter thereof. 4. The high-strength pintle veneer tie of claim 2, 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. 5. The high-strength pintle veneer tie of claim 2, wherein the veneer tie insertion portion further comprises: a compression dimensioned to interlock with a reinforcement wire; and,a reinforcement wire sized and shaped for being disposed in the compression;whereby upon insertion of the reinforcement wire in the compression, a seismic construct is formed. 6. The high-strength pintle veneer tie of claim 2, wherein the veneer tie is a metal alloy constructed of material selected from a group consisting of mill galvanized steel, hot-dip galvanized steel, stainless steel, and bright basic steel. 7. A high-strength pintle anchoring system for use in a wall having an inner wythe and an outer wythe spaced apart 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 for extending into the cavity, the free end of the wall anchor comprising:a receptor portion adapted to be disposed in the cavity; and,a wire-formative veneer tie comprising: an insertion portion for disposition in the bed joint of the outer wythe;two cavity portions contiguous with the insertion portion, the cavity portions being interconnected with one another; 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 and the second ribbon pintle each further comprising:an elbow portion configured for interconnection with the receptor portion of the wall anchor; and,a U-shaped securement portion having a first end contiguous with the elbow portion and opposite the cavity portion, the U-shaped securement portion having a second end and being free from direct connection to the respective cavity portion, the second end spaced apart from the elbow portion, the U-shaped securement portion being compressively reduced such that the U-shaped securement portion has a thickness and a width greater than the thickness,whereby upon interconnection of the veneer tie with the wall anchor, the interconnecting portion prevents the veneer tie from disengaging from the wall anchor, while allowing for restricted vertical adjustment. 8. 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. 9. The high-strength pintle anchoring system of claim 7 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. 10. The high-strength pintle anchoring system of claim 9 wherein the receptor portion further comprises a single eyelet adapted to be disposed substantially horizontal in the cavity, the interconnecting portion dimensioned to interconnect with the receptor portion. 11. The high-strength pintle anchoring system of claim 10, the wall anchor further comprising: two anchor wire formatives adapted to be fixedly attached to a reinforcement ladder or truss, the anchor wire formatives having at least two legs adapted for extending into and terminating within the cavity and being affixed to the eyelet. 12. The high-strength pintle anchoring system of claim 11 wherein each U-shaped securement portion is dimensioned to restrict movement of the interconnecting portion beyond the eyelet and wherein upon insertion of the veneer tie within the eyelet, the U-shaped securement portion restricts vertical movement of the veneer tie. 13. The high-strength pintle anchoring system of claim 12 wherein the elbow portions have a thickness and a width greater than the thickness, the width of each elbow portion being substantially parallel to the longitudinal axes of the legs of the wall anchor. 14. The high-strength pintle anchoring system of claim 13, wherein the veneer tie insertion portion further comprises: a compression dimensioned to interlock with a reinforcement wire; and,a reinforcement wire adapted to be disposed in the compression;whereby upon insertion of the reinforcement wire in the compression, a seismic construct is formed. 15. The high-strength pintle anchoring system of claim 9, the wall anchor further comprising: a surface-mounted sheetmetal bracket adapted to be fixedly attached to the columns of the inner wythe, the sheetmetal bracket being L-shaped and having a mounting portion and an extending portion, the extending portion comprising the receptor portion. 16. The high-strength pintle anchoring system of claim 15 wherein the receptor portion further comprises an elongated aperture and wherein each U-shaped securement portion is dimensioned to restrict movement of the interconnecting portion beyond the elongated aperture. 17. The high-strength pintle anchoring system of claim 16 wherein upon installation a width of each elbow portion is substantially normal to the mounting portion of the sheetmetal bracket. 18. The high-strength pintle anchoring system of claim 17 the veneer tie insertion portion further comprises: a compression dimensioned to interlock with a reinforcement wire; and,a reinforcement wire adapted to be disposed in the compression;whereby upon insertion of the reinforcement wire in the compression, a seismic construct is formed.
