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.

What is claimed is: 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 masonry wall with a ladder-or truss-type wall reinforcement means embedded therein, said system comprising, in combination: a wall anchor adapted to be secured to said inner wythe, said wall anchor connected to said reinforcement means and extending from said reinforcement means into said cavity, said wall anchor, in turn, comprising: at least one pair of pintle-receiving eye wires extending from said inner wythe having a receptor portion, upon installation thereof, extending into said cavity and terminating therewithin; a receiving aperture in each receptor portion and, with said receptor installed in said wall structure, each receptor portion is disposed horizontally in said cavity; a snap-in wire tie adapted for embedment in said outer wythe, said snap-in wire tie having a pair of pintles and an insertion portion, each said pair of pintles being disposed in one pair of said pintle-receiving eye wires, said snap-in wire tie, in turn, comprising: at least two wire housings formed in said insertion portion adapted to securely clamp a wire disposed therewithin; and, at least one reinforcement wire portion disposed longitudinally in said outer wythe and securely inserted into said wire housings of said snap-in wire tie; whereby, upon securement of said wall anchor to said inner wythe, the disposition of said snap-in wire tie into receptor portions thereof, and the embedment of said insertion portion of said wire tie together with a reinforcement wire portion then a seismic construct is formed. 2. A seismic construction system as described in claim 1 wherein the force required to insert said reinforcement wire portion into said wire housings is between 5 and 12 lbs. 3. A seismic construction system as described in claim 1 wherein said pintles are formed from wire stock and said receiving apertures are dimensioned to minimize movement in a horizontal plane. 4. 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 with insulation thereon having a thickness requiring a high-span cavity, said system comprising, in combination: a wall anchor of low-profile construction adapted to be secured to said inner wythe, in turn, comprising: at least one receptor portions extending from said inner wythe having a receptor portion, upon installation thereof, extending into said cavity and terminating therewithin; a receiving aperture in each receptor portion and, with said receptor installed in said wall structure, each said receptor portion is disposed horizontally in said cavity; a snap-in wire tie of low-profile construction adapted for embedment in said outer wythe, said snap-in wire having a rear leg and a low-profile insertion portion, said rear leg for interlocking with said receptor portions, said snap-in wire tie, in turn, comprising: at least two wire housings formed in said low-profile insertion portion for encapturing a reinforcement wire portion adapted to securely clamp a wire disposed therewithin; and, at least one reinforcement wire portion disposed longitudinally in said outer wythe and securely inserted by a force between 7 and 12 lbs. into said wire housings of said snap-in wire tie; whereby, upon securement of said wall anchor to said inner wythe, the disposition of said snap-in wire tie into receptor portions thereof, and the embedment of said insertion portion of said wire tie together with a reinforcement wire portion then a seismic construct is formed. 5. A seismic construction system as described in claim 4 wherein said rear leg is formed from wire stock and said receiving aperture is dimensioned to minimize movement in a horizontal plane.
