DriftTrak® DTLB

TSN_DriftTrak_DTLB
US Patent #7,503,150
 

DriftTrak® DTLB is designed to provide flexibility of attachment of wall panels to structure. DriftTrak DTLB can accommodate lateral movement or horizontal tolerance in a bypass attachment condition. The clips are manufactured to fit into the DriftTrak and provide free lateral movement of the structure with a rigid connection to the stud.  Standard DriftTrak DTLB clips have notches to facilitate horizontal movement of the clips inside the track over fastener heads. If this feature is not needed (i.e. welded track to structure or no drift requirements), use DriftTrak DTLB-HD clips without notches for greater F2 outward load capacity. Locking Angle DT-LA is available to lock the horizontal movement of the wall panel after installation for cases of no drift requirements. DriftTrak is available in 12’ lengths.

Value

  • Positive, load rated mechanical attachment to stud
  • Lateral movement or horizontal tolerance amount limited only to stud spacing and wall termination
  • Available detail to lock lateral movement after panel installation
  • Leg stiffener pre-installed in each clip
  • Grooves in 1” leg pass over fastener heads

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, 97mil minimum thickness (12 gauge, 0.1017" design thickness) with ASTM A653/A653M G90 (Z275) hot dipped galvanized coating.

Track Material: ASTM A1003/A1003M Structural Grade 50 (340) Type H, ST50H (ST340H): 50ksi (340MPa) minimum yield strength, 65ksi (450MPa) minimum tensile strength, 97mil minimum thickness (12 gauge, 0.1017" design thickness) with ASTM A653/A653M G60 (Z180) hot dipped galvanized coating.

  1. Attach DriftTrak® DTLB to structure at required spacing with specified fasteners.
    - Stiffener and clip have triangular edge for ease of installation.
  2. Twist clip into track. Ensure stiffener is in place prior to installation into track.
    - The clips can be dropped in at any point along the track and rotated to lock in.
  3. Lift panel into place.
  4. Slide clip toward stud so they are flush with the stud web.
  5. Attach stud to clip through guide holes with specified fasteners.

    LOCKING LATERAL MOVEMENT AFTER PANEL INSTALLATION
    Fasten 1.5" x 2" x 0.5" - 68mil angle to DriftTrak components using #12 screws (not included). Locking is recommended at 4 ft. spacing or 3rd stud, max.

Nomenclature

DriftTrak DTLB is classified by multiplying stud depth by 100, followed by "HD," based on F2 strength required. Refer to load tables.*

Example: 6" stud depth, with an outward load (F2) of 1,000 lbs
Designate: DriftTrak® DTLB600-HD

* Clips and track sold separately.
** Notches are standard in DriftTrak DTSLB.  For greater F2 outward load capacity, use DTLB-HD clips without notches. Refer to Allowable Load Table.

Notes:

  • Allowable load tables incorporate eccentric loading of fasteners.
  • Loads listed reflect force in a single direction. When multiple loads react on the connection, it is the responsibility of the designer to check the interaction of forces.
  • Torsional effects are considered on screw group for F3 allowable loads. It is assumed that all of the torsional moment is taken by the connection to the stud.
  • Design loads are for attachment of DriftTrak DTLB to stud only. Load tables reflect horizontal loads (F2) and vertical loads (F3)
  • Use 8” fastener spacing in track to structure (or weld on each side of track). Size of fasteners or weld is engineered by others.
  • Allowable loads have not been increased for wind, seismic, or other factors.
  • Clips are manufactured to fit into the DriftTrak and provide a rigid connection to the stud, and free lateral movement of the structure.
  • Allow a minimum of 0.875" from the structure to the inside flange of the bypassing stud to allow for track attachment.
  • One row of bridging is recommended at a maximum distance of 18" from DriftTrak to resist torsional effects.

* Notches are standard in DriftTrak DTLB. For greater F2 outward load capacity, use DTLB-HD clips w/o notches. Refer to Allowable Load Table.
