StiffClip® CL Floor Tie

   
Product Application

The StiffClip® CL series’ unique design allows for the connection of steel studs to the building’s structure by incorporating stiffened legs of a 90o angle to increase bending strength. StiffClip CL resists vertical, horizontal, and torsional loads. The allowable design load table is based on the use of StiffClip as it is attached to various steel stud wall material thicknesses and yield strengths. Allowable loads consider loads on the clip and screw fasteners to the stud web. Pre-drilled holes for attachments to both deck and stud provide installers with increased efficiency. The designed attachment of StiffClip to the primary structure is dependent upon the base material’s properties (e.g. steel or concrete) and the design configuration.

 

 

Material CompositionStiffClip CL Dimensions

Steel: ASTM A653/A653M, Grade 50 (340), 50ksi (340MPa) minimum yield strength, 65ksi (450MPa) minimum tensile strength, G-90 (Z275) hot-dipped galvanized coating. Material thickness = 68mil (14 gauge, 0.0713” design thickness) or 118mil (10 gauge, 0.1242” design thickness). ”H” Plate: Z33, Carbon Steel Class C, ASTM- A 27/A 27M-95, GRADE 65-35 Zinc Plate ASTM-B-633 Type 2 Yellow.

Allowable load tables incorporate eccentric loading of fasteners. Values with welded connection may increase.

When determining the allowable load of fasteners securing StiffClip to the base material and clip to stud, consider the following:

  • Fasten within ¾” from the angle heel (centerline of the 1½” leg), using pre-drilled holes if desired
  • Center guide hole is .5” in diameter
  • Middle guide holes are .313” in diameter
  • Outer guide holes are .172” in diameter
  • Guide holes are in place for fastener installation efficiency. Number of fasteners determined by designer
  • Attachment to stud is made with #12 screws, symmetrically placed

StiffClip CL Nomenclature

The StiffClip CL product group is produced in three thicknesses (68mil, 118mil, and 118mil(H)) and six stud member depths. The StiffClip CL118(H) utilizes a plate in the 1½” leg. To specify StiffClip CL on drawings, multiply stud depth by 100, followed by the appropriate material thickness, based on strength required.

Example: 6” stud, uplift load of 650lbs.
Designate: StiffClip CL600-68.
StiffClip CL Value
  • Guide holes for connections to stud and deck
  • Stiffeners for additional strength
  • Utilizes only mill-certified, 50ksi steel
  • Reduces material (replaces heavy steel angles)
  • Extensively tested
Stiff Clip CL Anchor Bolt Design

The following equation for tension force in the anchor is derived using the assumed bearing stress distribution shown in the figure to the right. This assumed stress distribution provides a conservative anchor force approximation.

StiffClip CL Anchor Design
StiffClip CL Installation
  1. Place StiffClip CL at bottom of stud.
  2. Attach clip to deck with approved anchor.
  3. Secure clip to stud with required amount of symmetrically placed #12 screw fasteners.
  4. If the (H) Piece is used, secure to clip with approved anchor to deck.

  • 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.
  • All guide holes may not require fasteners. Fastener amount determined by the designer. Screw fasteners should be symmetrically placed in guide holes. Refer to screw pattern diagrams above for placement.
  • Allowable loads have not been increased for wind, seismic, or other factors, and are based on use of #12 screws.
  • Torsional effects are considered on screw groups for F2 allowable loads.
  • M1 allowable moments are based on 0.02 rad. (1.1 degrees) rotation serviceability limit.
