The Block Shear™ Connector assembly consists of a Block Shear™ Connector Plate, a V-Tie™, and an optional Insulation Support.

The Block Shear™ Connector Plate component, presented in Figure 1, is manufactured from 16 gauge (1.61 mm [0.063"] thick) sheet metal conforming to ASTM Standard A570, and is available in hot dipped galvanized finish (conforming to CSA CAN3-A370 and ASTM A123 requirement of 401 g/m^2/side [1.31 oz/ft^2/side] of zinc coating), and stainless steel.

The length of the Block Shear™ Connector can vary to accommodate block width (b), of 90 (4"), 140 (6"), 190 (8"), 240 (10") and 290 mm (12"), insulation thickness (i), of 0 mm (0")and up, and air space width (a), of 25 mm (1") and greater.

Shear keys and corrugated sections provide for adequate fixity within the concrete block wythe. The notch in the plate assures proper positioning within the concrete block wythe.

Thermal bridging reducing holes are incorporated within the insulation thickness portion of the Block Shear™ Connector Plate.

The V-Tie™, as shown in Figure 2, is manufactured from 4.76 mm (0.19") diameter wire conforming to CSA Standard G30.3, and is available in hot dipped galvanized (conforming to CSA CAN3-A370 and ASTM A123 requirement of 458 g/m2/side [1.5 oz/ft2/side] of zinc coating), or stainless steel.

The legs of the V-Tie™ are mortared into place at the centerline of the brick veneer. V-Tie™ sizes of 60 (2.4"), 80 (3.1"), 100 (3.9"), 120 (4.7"), 140 (5.5"), 160 (6.3"), 180 (7.1"), 200 (7.9"), 225 (8.9") and 250 mm (9.8") lengths are available.

The Insulation Support is manufactured from polyethylene and is optionally used to secure the sheet insulation in place.

A Block Shear™ Connector assembly is shown in Figure 4, with an installation wall section given in Figure 5.
