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.

ICF Ledger Connectors

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. USA Patent Application Number 17/120,457.


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

  1. Fasteners for wood ledgers provided with part
  2. Loads apply to ICF foam thickness of 3¼ or less.
  3. Concrete should have a minimum compressive rate of f'c = 2,500 psi (17.25 MPa)
  4. The bolts of BURMON-ICFWL must be no closer than 4 inches to the top of wall.

NOTE:

The Allowable Load Table is calculated in accordance with ASTM D7147-11 Section 13, the allowable downward load is calculated as the lesser of:

  1. The lowest ultimate load per hanger divided by 3.
  2. The average, over each hanger in each specimen, load that produces a vertical deflection of 0.125 inches at the bottom of the hanger with respect to the wall. Refer to Intertek Engineering report K9541.01-119-42 RO for Test results.
This Table Addresses Vertical Load Applications only for ICF Foam Thickness Up To 3¼ inches
