A high-strength rectangular pintle veneer tie and cavity wall anchoring system employing the same is disclosed. The rectangular wire formative construct optionally includes a square cross-section that provides greater volumetric occupancy than that of a similar diameter circular wire formative. The interengaging portions and insertion portion are optionally compressed for greater strength and the rectangular shaped interengaging portion provides a locking interconnection within the anchor precluding significant movement lateral with or normal to the inner wythe.

A high-strength pintle anchoring system as described in claim 1 wherein said one or more receptor portions further comprise a single eyelet with a substantially oval opening therethrough, said single eyelet being welded closed; and, each said interengaging end portion is dimensioned to be secured within said single eyelet. 3. A high-strength pintle anchoring system as described in claim 1 wherein said insertion portion is compressively reduced. 4. A high-strength pintle anchoring system as described in claim 3 wherein said veneer tie insertion portion further comprises: a compression dimensioned to interlock with a reinforcement wire; and,a reinforcement wire disposed in said compression;whereby upon insertion of said reinforcement wire in said compression a seismic construct is formed. 5. A high-strength pintle anchoring system as described in claim 1 wherein said one or more interengaging end portions are compressively reduced in thickness thereby increasing the tension and compression rating of the wire formative. 6. A high-strength pintle anchoring system as described in claim 1 wherein said inner wythe is formed from successive courses of masonry block with a bed joint of predetermined height between each two adjacent courses, said inner wythe 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; and,wherein the major cross-sectional axis of each said interengaging end portions is substantially parallel to the longitudinal axes of said legs of said wall anchor. 7. A high-strength pintle anchoring system as described in claim 1 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; and,wherein the major cross-sectional axis of each of said interengaging end portion is substantially normal to said wallboard panels. 8. A high-strength pintle anchoring system as described in claim 7 wherein said one or more receptor portions further comprise two apertures disposed substantially horizontal in said cavity and spaced apart at a predetermined interval; and, wherein each of said two apertures are shaped substantially similar to the cross section of each of said interengaging end portions and said interengaging end portions are dimensioned to be secured within one of said openings of said two apertures. 9. 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 inner wythe being a dry wall structure having wallboard panels mounted on columns or framing members, said system comprising: a wall anchor fixedly attached to said inner wythe and having a free end thereof extending into said cavity, said free end of said wall anchor comprising one or more receptor portions disposed in said cavity, said one or more receptor portions being openings disposed substantially horizontal, said wall anchor being 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; and,a wire-formative veneer tie having a substantially rectangular cross-section, said veneer tie further comprising: an insertion end portion for disposition in said bed joint of said outer wythe;one or more cavity portions for disposition in said cavity, said cavity portions contiguous with said insertion end portion; and, one or more interengaging end portions for disposition into said one or more receptor portions of said wall anchor, each said interengaging end portion contiguous with said cavity portions and set opposite said insertion end portion, wherein said one or more receptor portions further comprise a single eyelet with a substantially oval opening therethrough, said single eyelet being welded closed; and, each said interengaging end portion is dimensioned to securely interlock within said single eyelet. 10. A high-strength pintle anchoring system as described in claim 9 wherein said wire formative veneer tie has a 27% higher volumetric occupancy than that of a round wire having a diameter substantially equal to the lesser of a height and a width of the veneer tie in cross section. 11. A high-strength pintle 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, said cavity in excess of four inches, said backup wall formed from a plurality of successive courses of masonry block with a bed joint of predetermined height between each two adjacent courses, said high-span anchor and reinforcement device comprising, in combination: a wall reinforcement with an upper surface in one plane and a lower surface in a plane substantially parallel thereto, said wall reinforcement adapted for mounting in said bed joint of said backup wall; at least one wall anchor fusibly attached at an attachment end thereof to said wall reinforcement, and, upon installation in said bed joint of said backup wall, extending between said plane of said upper surface and said plane of said lower surface from an attachment end thereof to the vertical surface of said backup wall; said wall anchor, in turn, comprising:at least one extended leg portion for spanning said cavity, said extended leg portion having a free end contiguous therewith, opposite said attachment end, and having one or more receptor portions therein; and,a wire-formative veneer tie having a substantially rectangular cross-section, said veneer tie further comprising:an insertion end portion for disposition in said bed joint of said outer wythe;two cavity portions for disposition in said cavity, said cavity portions contiguous with said insertion end portion; and,two interengaging end portions for disposition into said one or more receptor portions of said wall anchor, said interengaging end portions contiguous with said cavity portions and set opposite said insertion end portion. 12. A high-strength pintle anchoring system as described in claim 11 wherein said wall anchor has two extended leg portions each having a receptor portion, said receptor portions further comprising two eyelets disposed substantially horizontal in said cavity and spaced apart at a predetermined interval; and, wherein said interengaging end portions are dimensioned to be secured within said eyelets. 13. A high-strength pintle anchoring system as described in claim 12 wherein the major cross-sectional axes of said interengaging end portions are substantially parallel to the longitudinal axes of said leg portions of said wall anchor. 14. A high-strength pintle anchoring system as described in claim 13 wherein said wire formative veneer tie has height and width dimensions which are substantially equivalent forming a substantially square cross-section; and, said interengaging end portions are compressively reduced. 15. A high-strength pintle anchoring system as described in claim 14, wherein said veneer tie has a 27% higher volumetric occupancy than that of a round wire having a diameter substantially equal to the height and width of the veneer tie. 16. A high-strength pintle anchoring system as described in claim 13, wherein said insertion portion is compressively reduced, said insertion portion further comprising: a compression dimensioned to interlock with a reinforcement wire; anda reinforcement wire disposed in said compression;whereby upon insertion of said reinforcement wire in said compression a seismic construct is formed.
