1 Connect Easily to Insulated Forms The ICF Ledger Connector System is engineered to solve the challenges of mounting wood or steel ledgers to walls built with insulated concrete forms (ICF). This flier provides information on the various products we have to serve the ICF market. The ICFVL is a 4-gauge galvanized steel connector designed to provide both vertical and lateral in-plane resistance. The embedded legs are embossed for additional stiffness and the holes allow for concrete to flow through and around the connector. The exposed flange on the face of the ICF provides a structural surface for mounting either a wood or steel ledger. See the current Simpson Strong-Tie Wood Construction Connectors catalog or strongtie.com for additional information. 8" 5 3 6" of ICFVL: Snap a line for the bottom of the ledger and mark the on-center spacing Use the ICFVL to mark the kerf locations in the ICF Cut the kerfs as marked 5 8" ICFVL 6" Insert the ICFVL flush to the face of the ICF Place concrete (min. f'c = 2,500 psi) tip: Use a screw through diamond hole in face of ICFVL and into web to hold in place during concrete pour (remove prior to ledger installation). (for wood) ICFVL-W and ICFVL-CW Attachment of Wood Ledger Slip the appropriate ledger connector underneath the wood ledger (as shown) Install the eight ICF-D3.62 screws partially into the ledger Position bottom of the ledger level to the chalk line and drive the screws through the wood and into the ICFVL All screws should be located at least 2" from the edge of the ICFVL Note: Do not splice at the ICFVL-W or ICFVL-CW location. Attachment of Steel Ledger Position bottom of the ledger level to the chalk line and drive the required number of screws through the steel ledger and into the ICFVL All screws should be located at least 2" from the edge of the ICFVL Space screws evenly (800) strongtie.com 208 Simpson Strong-Tie Company Inc.

Minimum concrete compressive strength (f' c ) is 2,500 psi. 5. Use the unity equation when applying vertical and lateral loads simultaneously.

Accordingly, use this product in dry, interior applications only. Wood Ledgers Allowable Loads (lb.) ASD Vertical Lateral,940,905. Use (8) ICF-D3.62 screws (provided). 2. Loads apply to ICFs with foam thickness 3 4" or less. 3. Loads assume a minimum Spruce-Pine-Fir ledger. 4. Loads may not be increased for short-term loading. 5. The ICFVL must be installed no closer than 4" below the top of the wall to achieve the allowable loads shown. For installations where the ICFVL is installed less than 4" from the top of the wall (including flush applications) multiply the allowable loads by Bottom of ledger ICFVL Typical Wood Ledger with ICFVL and ICFVL-W (ICFVL-CW for LVL ledger similar) Incorrect ICFVL Spacing to Replace Anchor Bolts 2" Diameter Bolts 5 8" Diameter Bolts 2" o.c. 24" o.c. 36" o.c. 48" o.c. 2" o.c. 24" o.c. 36" o.c. 48" o.c. 48" 48" 48" 48" 48" 48" 48" 48" (2) 5 8" Diameter Bolts 3 4" Diameter Bolts 2" o.c. 24" o.c. 36" o.c. 48" o.c. 2" o.c. 24" o.c. 36" o.c. 48" o.c. 24" 48" 48" 48" 42" 48" 48" 48" Recommended Splicing Max. 2" Max. 2". This table addresses vertical load applications only. 2. The Designer may specify different spacing based on the load requirements. 3. Spacings are based on perpendicular to grain capacity of bolt in Spruce- Pine-Fir wood ledger compared to tested value of ICFVL with a maximum allowable spacing of 48". 4. Connector spacing requirements are based on a C D =.00 load duration. Contact Simpson Strong-Tie for alternate load durations. 5. Bolt design values are based on 2005 NDS Table E for a dowel bearing strength of F e = 7,500 psi in concrete with a minimum f' c = 2,500 psi and a 6" anchor embedment with a bolt bending yield strength of F yb = 45,000 psi.

For steel ledgers, the 68 mil ledger spacing is closer than the 54 mil ledger because the calculated load of a bolt is higher in a thicker piece of steel. 3. Steel ledger values are based on steel.

6 ICF Connectors The following spacing tables are an alternative to the ICFVL spacing to replace anchor bolts tables or allowable loads on page 5. They give the spacing of the ICFVL Ledger Connectors based on the allowable vertical load of the connector, the load on the floor and the span of the joists. The Designer must determine the design load, the ledger design and joist design. This table is useful if the Designer already has loads and spans, but not necessarily anchor bolt spacing. Dead Load Uniform Loads Live Load ICFVL Spacing for SPF Wood Ledger (in.) Joist Span (ft.) See notes below. Dead Load Uniform Loads Live Load ICFVL Spacing for Steel Ledger (in.) 54 mil Joist Span (ft.) This table addresses vertical load applications only. 2. Values shown are maximum spacing distances (in.) based on simple span, uniformly loaded conditions and do not consider concentrated loads. 3. Joist and ledger are to be designed by others. 4. Allowable loads are based on testing, with no further increases allowed. 5. Tables above address vertical loads only. If connection is designed to simultaneously resist lateral loads, spacing will decrease. Contact Simpson Strong-Tie for current information. Alternative Retrofit Solution for Direct Attachment of Joist to Wall The HU and HUC hangers are heavy-duty face-mount joist hangers made from 4-gauge galvanized steel. These hangers can be directly attached to concrete wall using 4" x 3 4" Simpson Strong-Tie Titen 2 hex-head screws. See strongtie.com for more information on installation and use. Simpson Strong-Tie offers many retrofit products for attaching wood or steel framing members to concrete.
