DriftTrak® Headed Stud

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

DriftTrak® Headed Stud saves the time and expense of installing DriftTrak after the concrete slab 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 slab instead of welding to the pour stop angle and use of PAF's or anchors. Once concrete is poured, the DriftTrak is ready to support exterior steel framing using any DriftTrak Bypass clip (DTSLB-HD or DTLB-HD) 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 DrifTrak 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

  • Can be installed with any DriftTrak bypass clip
  • Headed Studs preinstalled
  • Eliminates the need to attach DriftTrak to the pour stop angle of the slab after it has been formed

Notes:

  • Recommended ASD steel strength per headed stud in tension or shear = 1,600 lbs.
  • 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 to resist torsional effects.
