Installation

Installation

Installation Sequence

Step 1 - Cut the end of the I Joist so that the top chord overhang [1] is a minimum of 50mm

Step 2 - Fix the TCHI to the joist using 10 No. of CSA 4.0x30mm screws. The end of the joist should be tight against the seat stiffener of the hanger, and the hanger should be plumb on the I-Joist end

Step 3 - Install the modified joist into its intended position.  Maximum gap [2] between the end of the joist and the supporting member is 15mm.  Minimum bearing [3] onto the supporting member is 35mm

Step 4 - Blocking pieces may be installed on top of the supporting member , in-between the I-Joist flanges, to give a level finish
