High-strength rectangular wire veneer tie and anchoring systems utilizing the same

摘要

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.

1. 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 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 one or more receptor portions comprising two eyelets disposed substantially horizontal in said cavity and spaced apart at a predetermined interval, each of said two eyelets being welded closed and having a substantially circular opening therethrough with a predetermined diameter; and, a wire-formative veneer tie having a substantially rectangular cross-section, said veneer tie having height and width dimensions which are substantially equivalent forming a substantially square cross section, said veneer tie further comprising:
an insertion end portion for disposition in said bed joint of said outer wythe, said insertion end portion having 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;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 being dimensioned to be secured within one of said two eyelets, each said interengaging end portion contiguous with said cavity portions and set opposite said insertion end portion, each said interengaging end portion comprising a pintle having a free end, each pintle having a substantially rectangular cross-section.
