ICF - MASONRY
VENEER TIE NOTES
| (i) |
The design values reflect both the windward and leeward
capacity of the ICF system, with the governing values
listed.
|
| (ii) |
The tie system recommended design load values were
formulated using working stress design following the procedures
of CSA CAN3-A370 “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).
|
| (iii) |
The allowable mortar pull-out or push-out 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 loads
listed above.
|
| (iv) |
The above design values relate to the capacity of
the FERO tie components.
|
| (v) |
The above design values are based on test results
utilizing a 127 mm (5”) cavity (102 mm (4”)
Plate and 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 the maximum
allowable by CSA-A370, ACI/ASCE/TMS/518 and U.B.C. For
stud construction every vertical stud should contain ties.
Design will ultimately govern spacing. |
V-Tie™: The 60 mm (2.4”) V-Tie™ is
utilized in the Rap-Tie system consisting of 25 mm (1”)
air space and 90 mm (3.5”) brick veneer. Other available
V-Tie™ sizes
are: 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 (9.8”) mm.
