SLOTTED RAP-TIE SYSTEM
The Slotted Rap-Tie System consists of a Slotted L-Plate, a V-Tie™ and an Insulation Support (optional). See Figures 1, 2, and 3 respectively.
Lateral loads applied to the brick veneer are transferred through the V-Tie™ to the Slotted L-Plate, which bears onto and is fastened to the structural backup wall, as shown in Figures 4 and 5, for attachment directly to the steel studs and on top of the protected drywall respectively. Note that “protected drywall” is defined by CSA Standard CAN3-A370 “Connectors for Masonry”, ACI/ASCE/TMS/518 and U.B.C.
The vertically orientated slot in the Slotted L-Plate through which the V-Tie™ is placed provides for 30 mm (1.2”) of construction adjustability and differential movement between the masonry veneer and the structural backup wall system.
The Slotted Rap-Tie can accommodate a range of insulation thickness of 0 (0”) to 105 mm (4”), and air space width of 25 mm (1”) and greater. For thicker insulation verification of structural performance is required. Please contact Fero.
SLOTTED RAP-TIE COMPONENTS
The V-Tie™ is inserted in the slotted hole of the Slotted L-Plate to run horizontally into the mortar joint of the brick veneer, with the legs of the V-Tie™ located at the centerline of the brick veneer.
Slotted L-Plate: The Slotted L-Plate is manufactured from 16 gauge (1.61 mm [0.063”] thick) sheet metal conforming to ASTM A570, and is available in hot dipped galvanized finish and stainless steel. The hot dipped galvanized finish conforms to the CSA CAN3-A370 and ASTM A153 requirement of 458 g/m2/side (1.5 oz/ft2/side) of zinc coating. The incorporation of voids in the Slotted L-PIate minimizes thermal conductivity through the tie.
V-Tie™: The V-Tie™ is manufactured from 4.76 mm (0.19”) diameter wire conforming to CSA Standard G30.3, and is available in hot dipped galvanized finish and stainless steel. The hot dipped galvanized finish conforms to the CSA CAN3-A370-04 and ASTM A153 requirement of 458 g/m2/side (1.5 oz/ft2/side) of zinc coating.
Insulation Support: The Insulation Support is manufactured from polyethylene. The Insulation Support is inserted over the L-PIate and pressed up against the insulation sheathing, preventing the insulation from separating from the backup wall. The friction fit between the Insulation Support and the Slotted L-PIate provides for the support of the insulation sheathing during construction, while the resistance provided to the Insulation Support by the V-Tie™, ensures a reliable, durable structural insulation
support system upon installation of the V-Tie™.
SLOTTED RAP-TIE GUIDELINES
The Slotted L-PIate specification length (L) refers to the total distance between the exterior face of the insulation sheathing and the exterior face of the structural backup wall component that the Slotted L-Plate is fastened on top of.
The 80 mm (3.1”) V-Tie™ is utilized in the Slotted Rap-Tie system consisting of 25 mm (1”) air space and 90 mm (3.5”) brick veneer. Other available V-Tie™ sizes are: 60 (2.4”), 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”).
The Insulation Support is standard.
SLOTTED RAP-TIE APPLICATIONS
The Slotted Rap-Tie system can be utilized in the applications shown in Figures 4, 5 and 6.
