Slotted L-Plate for Fero Rap-Tie System. The Fero Slotted L-Plate is manufactured from 16 gauge (1.61 mm [0.063”] thick) sheet metal conforming to ASTM A570. The The incorporation of voids in the Slotted L-Plate minimized thermal conduscitivity through the tie system.
The Fero Slotted Rap-Tie System
The Slotted Rap-Tie System consists of a Slotted L-Plate, a V-Tie™ and an Insulation Support (optional).
The Rap-Tie can accommodate a range of insulation thickness of 0 to 102 mm (0 to 4"), and air space width of 25 mm (1") and greater. The L-Plate accommodates the thickness of the insulation and projects 18 mm (0.7") into the air space. The V-Tie™ is inserted in the appropriate hole in the 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.
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, 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.
L-Plate: The overall length of the L-Plate is 18 mm (0.7") longer than the specification length (L). The specification length is the total distance between the exterior face of the insulation to the exterior face of the structural backup wall component that the L-Plate is fastened to.
