StiffClip® HE

TSN_StiffClip_HE(L)_Clip_Pair

US Patent #7,634,889
 

The StiffClip® HE series is used when connecting either beams to columns or headers to jambs. StiffClip HE transfers horizontal and large vertical loads from the beam to the column while incorporating a small shelf tab for alignment of JamStud® or box header during installation.

StiffClip HE(L) and HE(H) are designed to be used with typical box headers and incorporate stiffened ribs to protect the header ends from the effects of web crippling.

StiffClip HE(S) is designed to be used with a single TSN JamStud as the header member.  The StiffClip HE(S) is similar in design and thickness to StiffClip HE(H), but has a shorter height (3.5” for HE(S) versus 6” for HE(H)) to match the height of a single-piece header.

The allowable design load table shown below is based on the use of StiffClip when attached to various steel column and beam material thicknesses and yield strengths. The minimum combination of steel thickness and yield strength must be used when determining the maximum design load. Design loads listed below consider both loads on the clip and the #10 screws as they are fastened to the steel beam and column members.

Value

  • Guide holes for connections to column and JamStud or box header
  • Resists vertical and horizontal loads
  • Acts as a web stiffener
  • Tabs to hold header during installation
  • Reduces material (no jack studs or caps required)
  • Reduces labor expense
  • Extensively tested

Notes:

  • Torsional effects are considered on screw group for F2 & F3 allowable loads. It is assumed that half of the torsional moment is taken by the connection on one side and half is taken by the connection on the other side of the clip.
  • Attachment to stud is made with screws symmetrically placed. All guide holes may not require fasteners. Fastener amount determined by designer.
  • Allowable loads have not been increased for wind, seismic, or other factors.
  • The minimum combination of steel thickness and yield strength must be used when determining the maximum design load.
  • Design loads listed consider both loads on the clip and the #10 screws as they are fastened to the steel beam and column or jamb and header members.

* Refer to screw patterns below.

Notes

  • The standard clip does not include the four large holes in the web of the clip. Customs can be ordered by request.
  • Welded values do not apply to 43mil (18ga) Stiff Clip HE.
