An anchoring system for cavity walls is disclosed and includes a wall anchor and a high-strength partially compressed veneer tie. The anchor preserves the insulation integrity by sealing the insertion points in the inner wythe. The veneer tie utilizes ribbon cavity portions that are cold-worked and vertically compressed, 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, when part of the anchoring system, interengages with the wall anchor and is dimensioned to preclude significant veneer tie movement, preclude pullout and shed moisture and mortar within the cavity.

1. A high-strength wire formative 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 filled with mortar between each two adjacent courses, the veneer tie comprising: an insertion portion for disposition in the bed joint of the outer wythe, the insertion portion having an outer leg and an inner leg offset from the outer leg;two cavity portions contiguous with the insertion portion, each of the cavity portions comprising a ribbon cavity portion, each ribbon cavity portion being compressively reduced such that a height of each of the ribbon cavity portions is greater than a height of the insertion portion; and,an interconnecting portion contiguous with the two ribbon cavity portions and set opposite the insertion portion. 2. The veneer tie according to claim 1, wherein the height of each ribbon cavity portion is greater than a height of the interconnecting portion of the veneer tie. 3. The veneer tie according to claim 2, wherein each ribbon cavity portion is compressively reduced in such that the width of the ribbon cavity portion is smaller than a width of the insertion and interconnecting portions of the veneer tie. 4. The veneer tie according to claim 3, wherein the veneer tie outer leg has a swaged indentation for receiving a reinforcement wire. 5. The veneer tie according to claim 3, wherein each ribbon cavity portion when compressively reduced by one-third has a tension and compression rating of at least 130% of the rating for a non-reduced wire formative. 6. The veneer tie according to claim 5, wherein the veneer tie wire formative 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 surface-mounted anchoring system for use in the construction of a wall having an inner wythe and an outer wythe, the outer wythe formed from a plurality of successive courses with a bed joint, having a predetermined height and filled with mortar, between each two adjacent courses, the inner wythe having insulation disposed thereon and in a spaced apart relationship the outer wythe forming a cavity therebetween, the anchoring system comprising: a wall anchor adapted to be fixedly attached to the inner wythe, the wall anchor having two major faces being a mounting surface and an outer surface, the wall anchor further comprising:a pair of legs for insertion in the inner wythe, the pair of legs extending from the mounting surface with the longitudinal axes of the pair of legs being substantially normal to the two major faces; and,at least one apertured receptor portion contiguous with the outer surface;a wire formative veneer tie in an interlocking relationship with the apertured receptor portion, the veneer tie further comprising:an insertion portion for disposition in the bed joint of the outer wythe, the insertion portion having an outer leg and an inner leg offset from the outer leg;two cavity portions contiguous with the insertion portion, each of the cavity portions comprising a ribbon cavity portion, each ribbon cavity portion being compressively reduced such that a height of the ribbon cavity portion is greater than a height of the insertion portion; and,an interconnecting portion contiguous with the two ribbon cavity portions and set opposite the insertion portion. 8. The anchoring system according to claim 7, wherein the height of each ribbon cavity portion is greater than a height of the interconnecting portion of the veneer tie. 9. The anchoring system according to claim 8, wherein the width of each ribbon cavity portion is smaller than a width of the insertion and interconnecting portions of the veneer tie. 10. The anchoring system according to claim 9, wherein the height of each ribbon cavity portion is substantially perpendicular to the longitudinal axis of the pair of legs. 11. The anchoring system according to claim 10, wherein each ribbon cavity portion is compressively reduced in thickness by up to 75% of the original diameter thereof. 12. The anchoring system according to claim 11, wherein each ribbon cavity portion is 0.172- to 0.312-inch diameter wire. 13. The anchoring system according to claim 12, wherein each ribbon cavity portion is reduced by one-third and has a tension and compression rating at least 130% of the rating for a non-reduced wire formative. 14. The anchoring system according to claim 13, wherein the veneer tie outer leg further comprises: a swaged indentation for receiving a reinforcement wire; and,a reinforcement wire disposed in the indentation;whereby upon insertion of the reinforcement wire in the indentation a seismic construct is formed. 15. The anchoring system according to claim 14, wherein the veneer tie wire formative 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. 16. The veneer tie according to claim 1, wherein the height of each ribbon cavity portion is greater than a height of a remainder of the veneer tie. 17. The veneer tie according to claim 1, wherein the height of each ribbon cavity portion is greater than a width of the ribbon cavity portion. 18. The anchoring system according to claim 15, wherein the wall anchor comprises two substantially parallel apertured receptor portions. 19. The anchoring system according to claim 15, wherein the wall anchor further comprises at least one strengthening rib constructed to meet a 100 lbf. tension and compression rating. 20. The anchoring system according to claim 19, wherein each strengthening rib is impressed to depend from the mounting surface and configured, upon surface mounting of the wall anchor, to be pressed into the insulation of the inner wythe.
