  BLOCK SHEAR™ CONNECTOR BENEFITS

1.
The Block Shear™ Connector greatly increases the stiffness of the wall system through composite action, thereby significantly reducing the lateral deflection of the wall assembly.
2.
By providing composite action between the brick veneer and the concrete block backup wall, the block reinforcing requirements, the size of concrete block and thus the wall cost can all be reduced. These savings are again realized in greater useable floor space provided, and lower floor slab and foundation loads resulting in structural frame and foundation cost savings. Table 1 illustrates examples of the improved structural performance provided by the Block Shear™ Connector wall system.
3.
The Block Shear™ Connector provides fixity to the sheet insulation in all three directions, minimizing separation at sheet insulation junctions.

Notes

(i) Design lateral wind load = 1.0 kPa (20.8 psi) (pressure and suction).
(ii) Full mortar bedding is assumed for the 90 mm (3.5”) clay brick veneer. Face shell mortar bedding is assumed for the concrete block wythes. Type S mortar is assumed throughout.
(iii) Only those concrete block cores containing vertical reinforcing steel are assumed grouted.
(iv) A cavity width of 75 mm (3") is assumed.
(v) Block Shear™ Connectors are spaced horizontally at 800 mm (32") o.c. and vertically as per Figure 6.
