ICFVL Ledger Connector
System
NEW! The ICFVL Ledger
Connector System is engineered to solve the challenges
of mounting wood or steel ledgers to insulated concrete
form (ICF) walls. Simpson's new ICF component of the system,
the ICFVL, is designed to provide both vertical and lateral,
in-plane performance. The system is still quick, versatile
and easy to use but now provides so much more! There are
many benefits over traditional anchor bolting, including
better on center spacing in most cases, faster installation
and no protrusions. Simpson's ICFVL is made from galvanized,
14 gauge steel. The embedded legs are embossed for additional
stiffness and the hole allows 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.
Material: ICFVL - 14 gauge; ICFVL-CW and ICFVL-W
- 16 gauge
Finish: Galvanized.
Installation: ICFVL in ICF
Snap a chalk line for the bottom of the ledger.
Mark required on center spacing
Use ICFVL to mark kerfs locations.
Cut kerfs at marks.
Insert ICFVL flush to the face of the ICF.
Place concrete.
Wood Ledger Attachment
ICFVL-W or -CW
Slip appropriate ledger connector underneath the ledger.
Install the eight ICF-D3 screws partially into the ledger.
Position the ledger level to the chalk line and drive
the screws through the wood and into the ICFVL.
Steel Ledger Attachment
Position the ledger level to the chalk line and against
the ICFVL.
Attach with four 1/4-14x3/4", #3 drill point screws (not
provided).
All screws should be located at least 1/2" from the edge
of the ICFVL.
Space screws evenly. |

Typical Wood Ledger
Installation with ICFVL and ICFVL-W
|
|
1.Fasteners for wood ledger (D3) are
provided with the part and fasteners for steel
ledger are not provided.
2.Loads apply to ICF foam thicknesses of
2 5/8" or less. Contact Simpson for allowable
loads on thicker walls.
3.Alternately, #14 x 3/4" fastener may
be used.
4.Tabulated loads may not be increased.
5.Concrete f'c = 2500 psi minimum.
6.When combining download and lateral loads,
Designer shall evaluate as follows:
Design Download/Allowable Download + Design
Lateral Load/Allowable Lateral Load. |

|
1.The Designer may specify different
spacing based on the load requirements.
2.Spacings are based on perpendicular to
grain capacity of bolt in wood ledger compared
to tested value of ICFVL.
3.See F-ICFVL flier for additional connection
details.
4.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.
5.Steel ledger values are based on steel.
Fu = 60 ksi. |
