SLOTTED
BLOCK TIE (TYPE II) NOTES
| (i) |
The design values reflect both the windward and leeward capacity of the Slotted Block Tie (Type II) system, with the governing values listed.
|
| (ii) |
The tie system recommended design load value was formulated using working stress design following the procedures of CSA CAN3-A370-04 “Connectors for Masonry”, ACI/ASCE/TMS/518 and U.B.C. The value has been reduced to account for test result variation, and reflects a factor of safety of 2.25 (i.e. 75% of 3.0), as per Table 3 (A370).
|
| (iii) |
The allowable mortar pullout design load for the V-Tie™ embedded at the centerline of 90 mm (3.5”) brick veneer utilizing Type M, S or N mortar, exceeds or equals the recommended design load listed above.
|
| (iv) |
The allowable mortar pull-out or push-out design load for the Slotted Block Plate (Type II) embedded in the mortar joint of 90 (4"), 140 (6"), 190 (8"), 240 (10") and 290 mm (12") concrete block work utilizing Type S mortar, exceeds or equals the recommended design load listed above.
|
| (v) |
The above design values are based on test results utilizing a 127 mm (5”) cavity (25 mm [1”] air space). No insulation was used. Note that for smaller cavity widths and/or with the addition of insulation sheathing providing lateral tie support, increased tie system design loads and reduced tie system deflections may be realized.
|
| (vi) |
Maximum recommended spacing reflects maximum allowable by CSA-A370-04, ACI/ASCE/TMS/518 and U.B.C. Design will ultimately govern spacing. |
