ICF Ledger Connectors

PRODUCT CODES: ICFWL ICFSL

Burmon’s ICF Wood & Steel Ledgers utilize the Burmon ICF Connector System, a revolutionary double threaded cylinder bolt assembly that connects and anchors wood ledger brackets, wood and steel ledgers, joist hangers, I- joists, beams and trusses to insulated concrete forms (ICF) walls.

Burmon ICF Connector System

The cylinder bolt assembly is engineered with high capacity sheer points, which more efficiently absorbs the energy of the unsupported load transfer span, between the polystyrene inner and outer ICF wall. The embedded legs of the cylinder tube have openings to receive concrete and rebar (optional) and the high capacity bolts connect directly to the concrete within the ICF wall, enhancing strength, stiffness of connection, function and durability.

Features:

Fast & Easy to Install
Costs Significantly Less Than Ordinary Ledger Connectors
Revolutionary Double Cylinder Bolt Technology
Ledger Bracket, Bolts & Washers Supplied
Template Supplied for Marking Out Bolts
No Drilling Through Steel Plates
ICFWL designed for 1½ & 1¾ Wood Ledgers
25% Higher Capacity than other brand Ledger Connectors

* 5. ½ inch diameter, 3½ inch long Hex bolt

Fasteners for wood ledgers provided with part
Loads apply to ICF foam thickness of 3¼ or less.
Concrete should have a minimum compressive rate of f'_c = 2,500 psi (17.25 MPa)
The bolts of BURMON-ICFWL must be no closer than 4 inches to the top of wall.
* When attaching a deck to an ICF wall, place one ½ inch hex bolt 3½ inches long into each cylinder bolt hole as shown.

This table addresses vertical and pullout* load applications for foam thickness up to 3¼ inches. For foam thickness greater than 3¼ inches, contact our office for specific details.

The bolts of BURMON-ICFSL must be no closer than 4 inches to the top of wall.

The following spacing tables are an alternative to the ICFWL spacing to replace the building code-prescribed anchor bolt spacing for vertical loads only. They provide the recommended spacing of the ICFWL Ledger Connectors based on the Factored Vertical Resistance of the connector, the load on the floor and the span of the joist. The Designer must determine the design load, the ledger design and the joist design. This table is useful if the Designer already has loads and spans, but not necessarily anchor bolt spacing.

Values shown are maximum spacing distances (inches) based on two-span ledger and simple supported joists. It does not consider concentrated loads. The Engineer of Record can modify the spacing accordingly for other conditions.
Joist and ledger are to be designed by others.
Spacing tables address vertical load applications only. If the connection is designed to resist simultaneous lateral loads, spacing may decrease. Contact Burmon Building Products for additional information.
The ICFWL must be installed no closer than 4" below the top of wall to achieve the connector spacing.
The maximum distance between the end of the ledger and the first ICFWL is 12" as per the recommended splicing installation.
Tables above assume Principal Loads only with Importance Factor = 1.00. For other cases adjust spacing accordingly.
