DriftTrak® Headed Stud - PTS

TSN_DriftTrak_Headed_Stud_PTS
US Patent #7,503,150 & Patent Pending
 

DriftTrak® Headed Stud - PTS saves the time and expense of installing DriftTrak after the Post-Tensioned Concrete Slab (PTS) has been poured, by integrating it directly into the slab before pouring. The headed studs come preinstalled to the DriftTrak and function as the attachment to the post-tensioned slab instead of welding to the pour stop angle and use of PAF's or anchors. The DriftTrak is sized to fit above or under the high-strength tendon reinforcing at edge of slab. Once concrete is poured, the DriftTrak is ready to support exterior steel framing using any DriftTrak Bypass clip (DTSLB-PTS or DTLB-PTS) to accommodate vertical deflection and lateral drift requirements or provide a rigid attachment to the floor slab.

As with standard DriftTrak, DriftTrak Headed Stud also simplifies panel installation by allowing the installer to twist DriftTrak Bypass clips onto the DriftTrak as the prefabricated wall panel is hoisted into position, so they can be quickly and easily aligned to studs for attachment before the crane is unlocked from the panel. Vertical deflection and drift movement can be left intact or a locking angle can be installed to prevent lateral drift if not required.

Value

  • Fits above or under the high-strength tendon reinforcing at edge of slab
  • Can be installed with DriftTrak bypass and rigid clips
  • Headed Studs preinstalled
  • Eliminates the need to attach DriftTrak to the pour stop angle of the slab after it has been formed

Track Nomenclature

DriftTrak® Headed Stud - PTS comes in 12’ lengths, with headed studs in a single row (See drawing below). To specify DriftTrak - PTS, list "DTH-PTS," followed by the length.

Example: DriftTrak® DTH-PTS - 12ft.

* Clips and track sold separately.

TSN_DriftTrak_DTLB_PTS_Dimensions

DTLB-PTS & DTSLB-PTS

DriftTrak® Headed Studs are to be installed with DriftTrak Bypass clips DTLB-PTS and DTSLB-PTS to better facilitate panel installation while accommodating vertical deflection and lateral drift requirements in floor slab bypass conditions. DriftTrak Connectors are sold separately.

Connector Nomenclature

DriftTrak® DTLB-PTS & DTSLB-PTS are made for 6" studs. They are classified by multiplying stud depth by 100, followed by "PTS."

Example: Vertical Deflection required
Designate: DriftTrak® DTSLB600-PTS

* Clips shown are left versions of DriftTrak DTLB-PTS & DTSLB-PTS. Right side versions can be made as custom parts.
** Clips and track sold separately.

Notes:

  • Recommended ASD steel strength per headed stud in tension or shear = 1,600 lbs. Designers must check headed stud tension and shear anchorage capacity in concrete per ACI 318 based on actual headed stud edge distance and concrete compressive strength. For more information, call TSN Technical Support at 1-888-474-4TSN.
  • 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 to stud only. Load tables reflect horizontal loads (F2) and vertical loads (F3)
  • Allowable loads have not been increased for wind, seismic, or other factors.
  • Clips are manufactured to fit into the DriftTrak and provide a rigid/slip connection to the stud, and free lateral movement of the structure.
  • One row of bridging is recommended at a maximum distance of 18” from DriftTrak if no other stud lateral restraint is present.
