ABVTS NOTES
- The above design values reflect both the windward and leeward capacity of the Adjustable BVTS tie system, with the governing values listed.
- The tabulated tie system design values were 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 values have been reduced to account for test result variation, and reflect a factor of safety of 2.25 (i.e., 75% of 3.0), as per Table 3 (A370).
- The allowable mortar pull-out and push-out design load for the V-Tie™ embedded at the center line of 90 mm (3.5”) brick veneer utilizing Type M, S or N mortar, exceeds or equals the recommended design load listed above.
- The above design values relate to the capacity of the FERO tie components. Compatible fasteners capable of resisting the design load must be selected.
- The above design values are based on test results utilizing 78 mm (3.07”) BVTS and a 100 mm (4”) cavity. No insulation or drywall sheathing was used. Note that for smaller cavity widths and/or with the addition of insulation and gypsum sheathing providing lateral tie support, increased tie system design loads and reduced tie system deflections may be realized.
ABVTS SPECIFICATION GUIDELINES
| BVTS: | BVTS are available in 21 (0.83"), 31 (1.22"),
40 (1.57"), 52 (2"), 65 (2.56") and 78 mm (3.07") heights.
For penetrating only sheet insulation (i.e., fastening onto plywood sheathing, concrete block, concrete or clay brick), order the BVTS size to be the thickness of the insulation. For penetrating only gypsum sheathing, order the BVTS size to be the thickness of the gypsum sheathing. For penetrating gypsum sheathing and sheet insulation, order the BVTS size to be the sum of the thickness of the gypsum sheathing and sheet insulation. |
| AB-Clip: | The AB-Clip is standard. |
| V-Tie™: | The V-Tie™ is available in 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, and should be specified as the distance from the exterior face of the BVTS to the center line of the brick veneer. |
| BVTS Installation Caution:: | Ensure that all legs of the BVTS are in contact with the structural backup wall systems. |
