The Slotted Stud Tie (Type 1) a system consists of a Slotted Stud Plate (Type 1) (which is a vertically oriented plate), a V-Tie™ (a V-shaped wire), and an Insulation Support (a polyethylene retainer). Individual components are shown in Figures 1, 2 and 3. The assembly is shown in Figure 4, and the installed tie system is illustrated in Figure 5.

Lateral loads applied to the masonry veneer are transferred through the V-Tie™ to the Slotted Stud Plate which is fastened directly to a structural backing without any intervening material such as sheathing. The Stud Plate is fastened to a side surface of structural backing member such as a steel stud, wood stud, or miscellaneous steel (see Figure 5). The vertical slot along the outboard end of the Slotted Stud Plate through which the V-Tie™ is inserted provides a positive connection without the possibility of V-Tie™ disengagement during construction and in-service (in accordance with requirements in CSA A370 and ACI 530.1/ASCE 6/TMS 602). The slot permits up to 50 mm (2”) of in-situ vertical adjustment so that a bed joint in the masonry veneer will always be coincident with the V-Tie™ regardless of the placement of the Stud Plate vertically along the supporting structural member. The
vertical slot also accommodates vertical differential movement between the masonry veneer and the structural backing.

The Insulation Support, which inserted over the end of the Stud Plate and restrained by the V-Tie™, is used to securely and mechanically fix the cavity insulation in place.

The Slotted Stud Tie (Type 1) can accommodate a range of insulation thicknesses from 0 to 102 mm (0 to 4”), and air space widths of 25 mm (1”) and greater. The Slotted Stud Plate has sufficient length to accommodate the thickness of the cavity insulation and sheathing, and further extends 18 mm (0.7”) into the air space to expose its leading edge and facilitate in-situ placement of the V-Tie™ and Insulation Support. The V-Tie™
is inserted through the vertical slot along the leading edge of the Stud Plate and placed coincident with a mortar bed joint so as to extend horizontally and normally to the structural backing, thereby maintaining tie capacity. The legs of the V-Tie™ are positioned along the centreline of the masonry veneer within the placement tolerances permitted by the building code having jurisdiction. Adjustment normal to the wall is facilitated by on-site selection of an appropriate length of V-Tie™.

The Slotted Stud Tie (Type I) is capable only of transferring forces perpendicular to the wall and not parallel to the wall. Therefore, composite action cannot be achieved between the masonry veneer and the structural backing. For the design of shear connected masonry veneer/(steel) stud wall systems (i.e. composite wall construction), see Fero Stud Shear™ Connector.
