Snap-in wire tie
View Patent ↗A seismic construction system for a cavity wall is disclosed. The system is shown in three exemplary applications—a masonry backup wall with ladder—or truss-type reinforcement cooperating with a snap-in wire tie; a masonry backup wall with ladder—or truss-type reinforcement with a high-span wall anchor cooperating with a low-profile, snap-in wire tie; and a drywall backup wall with internal insulation, a sheetmetal wall anchor, and snap-in wire ties. The snap-in wire ties accommodate a continuous reinforcing wire for the outer wythe, which reinforcing wire snaps into the wire housings therefor with a predetermined force. With the interconnected wall and veneer anchors and the respective reinforcing elements a seismic construct is formed.
1. A seismic construction system for use in the construction of wall structures having an inner wythe and an outer wythe in a spaced apart relationship forming a cavity therebetween, said inner wythe is a drywall structure having wallboard facings disposed on vertical channel members, said system comprising, in combination:
a sheet metal wall anchor adapted to be secured by surface mounting on said wallboard facing, said wall anchor in turn, comprising:
at least one receptor portion extending opposite said inner wythe, each receptor attached thereto extending into said cavity and terminating therewithin;
a receiving aperture in each receptor portion and, upon installation, said receptor portion installed in said wall structure disposed in said cavity;
a snap-in wire tie adapted for embedment in said outer wythe, said snap-in wire tie comprising:
a wall-anchor-connector portion being disposed in said at least one receptor portion;
an insertion portion continuous with said wall-anchor-connector portion;
at least two wire housings formed in said insertion portion comprising:
a clamping jaw in each of said at least two wire housings for securely clamping a wire disposed therein in a snapped-in relationship, said clamping requiring an insertion force of from 5 to 10 lbs; and,
at least one reinforcement wire disposed longitudinally in said outer wythe and securely clamped within said wire housings of said snap-in wire tie;
whereby, a seismic construct is formed upon securement of said wall anchor to said inner wythe with said snap-in wire tie disposed in said receptor portion thereof and upon the embedment of said insertion portion of said snap-in wire tie and said reinforcement wire in the outer wythe.
2. A seismic construction system as described in claim 1 wherein each said receptor portion is a pintle-receiving aperture and, upon installation, said aperture is disposed in horizontally extending projections.
3. A seismic construction system as described in claim 2 wherein each wall-anchor-connector portion is a pintle.
4. A seismic construction system as described in claim 3 wherein each said pintle is a wire formative and each said receiving aperture is dimensioned to minimize movement towards and away from said inner wythe and limit side-to-side movement.
5. A seismic construction system as described in claim 1 wherein said snap-in wire tie has a rear leg, said rear leg for interlocking with said receptor portion.
6. A seismic construction system as described in claim 1 wherein said sheet metal wall anchor is a metal stamping.
7. A seismic construction system as described in claim 1 wherein said sheet metal wall anchor is attached to said vertical channel members of said inner wythe by sheet metal screws.
8. A seismic construction system for use in the construction of wall structures having an inner wythe and an outer wythe in a spaced apart relationship forming a cavity therebetween, said inner wythe is a masonry structure with insulation thereon having a thickness requiring a high-span cavity, said system comprising, in combination:
a sheet metal wall anchor adapted to be secured by surface mounting on said masonry structure, said sheet metal wall anchor in turn comprising:
at least one receptor portion extending opposite said inner wythe into said cavity and terminating therewithin;
a receiving aperture in each said receptor portion and, upon said installation, said receptor portion installed in said wall structure disposed horizontally in said cavity;
a snap-in wire tie adapted for embedment in said outer wythe, said snap-in wire tie comprising:
a wall anchor-connector-portion being disposed in said at least one receptor portion;
an insertion portion continuous with said wall-anchor-connector portion;
at least two wire housings formed in said insertion portion comprising:
a clamping jaw in each of said at least two wire housings for securely clamping a wire therein in a snapped-in relationship, said clamping requiring an insertion force of from 5 to 10 lbs; and
at least one reinforcement wire disposed longitudinally in said outer wythe and securely clamped within said wire housings of said snap-in wire tie;
whereby, a seismic construct is formed upon securement of said wall anchor to said inner wythe, with said snap-in wire tie disposed in said receptor portion thereof and upon the embedment of said insertion portion of said snap-in wire tie and said reinforcement wire in the outer wythe.
9. A seismic construction system as described in claim 8 wherein each said receptor portion is a pintle-receiving aperture and, upon installation, each said aperture is disposed in horizontally extending projections.
10. A seismic construction system as described in claim 9 wherein each wall-anchor-connector portion is a pintle.
11. A seismic construction system as described in claim 10 wherein each said pintle is a wire formative and each said receiving aperture is dimensioned to minimize movement towards and away from said inner wythe and limit side-to-side movement.
12. A seismic construction system as described in claim 8 wherein said snap-in wire tie has a rear leg, said rear leg for interlocking with said receptor portion.
13. A seismic construction system as described in claim 8 wherein said sheet metal wall anchor is a metal stamping.
14. A seismic construction system as described in claim 8 wherein said sheet metal wall anchor is attached to said masonry structure of said inner wythe by masonry screws.
15. A seismic construction system as described in claim 8 wherein said insertion portion is a wire formative.
