    Abstract: A veener wall anchor system interconnects a backup wall of block construction to a brick veneer wall. The system includes a wire joint reinforcement, embeddable in backup wall mortar joints, preformed with a plurality of thin plates welded thereto. When the joint reinforcement is embedded in the backup wall mortar joint, the plates extend outwardly therefrom. A wall of rigid insulation is placed against an outer face of the backup wall with the plates extending through the insulation. The plate includes an elongated aperture outwardly of the insulation for receiving an spring clip fastener which resiliently engages the insulation wall and contact with the backup wall. A pintle tie includes leg portions received in the plate aperture and a U-shaped portion embeddable in mortar joints of the veneer wall to interconnect the veneer wall with the backup wall.
