Abstract

A seismic construction system is disclosed having in combination: a masonry anchor, a wall tie, and a facing anchor. A reinforcing wire is disposed longitudinally in the inner masonry wythe and has attached spaced pairs of transverse wire portions. Each transverse wire portion extends into the cavity and terminates in an eye wire having an eye disposed vertically in the cavity and lying in a plane normal to the masonry wythe surface. The open end of the wall tie is threaded through a pair of eye wires of the masonry anchor, which eye wire portion extends into the cavity between the inner masonry wythe and the outer facing wythe. The masonry anchor is adapted to be embedded within the inner masonry wythe; and, after threading through the eye wires, the open end of the wall tie, within the outer facing wythe. The facing anchor includes a clip member which is constructed to accommodate the open end of the wall tie member and also a reinforcing wire disposed longitudinally in the facing wythe. Upon the closed end of the wall tie being captive in the eye wires of the masonry anchor and the open end of the wall tie and the clip of the facing anchor being embedded in the outer facing wythe, a seismic construct is formed with nominal endplay along the x- and z-axes and limited movement along the y-axis.

Dependent claims

A seismic construction system for use in the construction of wall structures having an inner masonry wythe and an outer facing wythe in spaced apart relationship forming a cavity therebetween, said system comprising, in combination:

a masonry anchor adapted to be embedded within said inner masonry wythe, in turn comprising:
a first reinforcement wire portion disposed longitudinally therein;
spaced pairs of transverse wire portions extending therefrom, each transverse wire portion attached at one end thereof to said first reinforcement wire portion and, when embedded in said inner masonry wythe, extending into said cavity and terminating therewithin;
an eye wire portion formed continuous with each said transverse wire portion and attached thereto at the end opposite the attachment end, said eye wire portion forming an eye adapted, when installed in said wall structure, to be disposed vertically in said cavity lying in a plane normal to the masonry wythe surface;
a wall tie member having a first end portion and a second end portion, said first end portion being captively disposed in one pair of said eye wire portions;
and,
a facing anchor adapted to be embedded within said outer facing wythe, said facing anchor, in turn, comprising:
a clip member comprising having a base member, said base member including:
first and second attachment means formed thereon, said second end portion of said wall tie member being secured to said first attachment means of said clip member;
at least one second reinforcement wire portion disposed longitudinally in said facing wythe and secured to said second attachment means of said clip member;
whereby upon embedment of said masonry anchor in said inner masonry wythe, the captive disposition of the wall tie member in the eye wire portion thereof, and the embedment of said facing anchor with the second end portion of the wall tie member secured thereto in said outer facing wythe;
a seismic construct is formed.

a reinforcing wire truss having a pair of reinforcement wires disposed parallel the one to the other;
a plurality of wire chords each attached to both said reinforcement wires in a predetermined configuration;
pairs of transverse wire portions spaced along and extending from said reinforcing wire truss, each transverse wire portion attached at one end thereof to said reinforcing wire truss and, when embedded in said inner wythe, extending into said cavity and terminating therewithin;
an eye wire portion formed continuous with each said transverse wire portion and attached thereto at the end opposite the attachment end, said eye wire portion forming an eye adapted, when installed in said wall structure, to be disposed vertically in said cavity lying in a plane normal to the masonry wythe surface;
a wall tie member having a first end portion and a second end portion, said first end portion being captively disposed in one pair of said eye wire portions;
and,
a facing anchor adapted to be embedded within said outer facing wythe, said facing anchor, in turn, comprising:
a clip member comprising having a base member, said base member including:
first and second attachment means formed thereon, said second end portion of said wall tie member being secured to said first attachment means of said clip member;
a reinforcement wire portion disposed longitudinally in said facing wythe and secured to said second attachment means of said clip member;
whereby upon embedment of said masonry anchor in said inner masonry wythe, the captive disposition of the wall tie member in the eye wire portion thereof, and the embedment of said facing anchor with the second end portion of the wall tie member secured thereto in said outer facing wythe;
a seismic construct is formed.
