VertiTrack® VTX

VertiTrack_VTX
US Patents #5,467,566 & #5,906,080

VertiTrack® VTX deflection track connects exterior curtain wall studs at head of wall to the building frame while allowing for vertical deflection of the structure of up to 1½” (¾” up and ¾” down). A VertiClip® SL is pre-assembled at 16”o.c. or 24”o.c. (or any pre-required stud spacing). VertiClip’s unique design provides both an anti-friction and anti-seizure connection between the clip and the stud web surface thereby preventing a transfer of vertical forces into curtain wall framing, which is not engineered to support axial loads. Use of VertiTrack VTX over friction-fit track assemblies minimizes liability through the utilization of positive mechanical attachments to the web of the stud.

Value

Material Composition

Clip Material: ASTM A1003/A1003M Structural Grade 50 (340) Type H, ST50H (ST340H): 50ksi (340MPa) minimum yield strength, 65ksi (450MPa) minimum tensile strength, 68mil minimum thickness (14 gauge, 0.0713" design thickness) with ASTM A653/A653M G90 (Z275) hot dipped galvanized coating.

Track Material: ASTM A1003/A1003M Structural Grade 33 (230) Type H, ST33H (ST230H): 33ksi (230MPa) minimum yield strength, 45ksi (310MPa) minimum tensile strength, 43mil minimum thickness (18 gauge, 0.0451" design thickness) with ASTM A653/A653M G60 (Z180) hot dipped galvanized coating.

The attachment of VertiTrack to the primary structure may be made with PAFs, screw/bolt anchors or weld and is dependent upon the base material (steel or concrete) and the design configuration.

  1. Attach VertiTrack VTX to deck with an engineered connection through each VertiClip SL.
  2. Connect stud to VertiTrack with provided screws through Step Bushings.

Nomenclature

VertiTrack VTX is manufactured in 12 ft. lengths. VertiTrack is designated by type (VTX), followed by stud depth in inches multiplied by 100 and stud spacing.

Example: 6" deep stud, 16" on center
Designate: VertiTrack® VTX600-16

Note:

  • Loads are the same as VertiClip® SL
  • Allowable load tables incorporate eccentric loading of fasteners. Values with welded connection may increase.
  • VertiTrack VTX is assembled with VertiClip SL pre-attached at 16" o.c. and 24" o.c.
  • Fasten within ¾" from the angle heel (centerline of the 1½" leg) to minimize eccentric load transfer.
  • VertiTrack VTX series is designed to support horizontal loads and should not be used in axial-load-bearing wall construction.
  • Total vertical deflection of up to 1½" (¾" up and ¾" down). Deflection requirements greater than ¾" (up and down) are available. Custom spacing is also available.
  • Allowable loads have not been increased for wind, seismic, or other factors.
  • #12 screws are provided with each step bushing for attachment to the stud web.
  • Strengthening ribs and guide holes are present in 3 ⅝" and 6" sizes.
