L. INTERMEDIATE FLOORS

To install ledgers for an intermediate floor system, we recommend using the Simpson ICF Ledger Connection System (Model #’s ICFVL, ICFVL-W, ICFVL-CW). This system includes a bracket that is placed through the foam into the concrete, and is cast in place to provide a secure anchor for the joist hangar which is attached with an engineered screw pattern of manufactured anchors. This system eliminates the removal of foam, extends the required distance between hangars, and is backed by Simpson engineering.

Alternative methods of anchoring floor ledgers to SmartBlockPlus walls require the removal of foam every 12 inches to accommodate the installation of one or two anchor bolts, depending on the span of the floor and its load requirements, and the installation. Details of these methods can be found in the SmartBlockPlus Installation Manual or the Prescriptive Method.
