Ledger board attachment (sort of)
These aren't ledger boards, as the beams will carry the second floor load. These are kind of end nailing boards for the floor sheathing, but the attachment method is similar. Drill a few holes in the board 15" o.c. Place the board on the wall so that the holes align with the solid "nodes" in the ICCF. Run all-thread through and use a plywood "washer" on the back. Drill additional holes and run all-thread into the form's hollow area. That piece will be cast into the concrete and is later used with a bolt and washer to actually attach the ledger.
Here's a tightened bolt (not cast) and a loose bolt (to be cast and tightened later).
I did another one using the plastic strapping shown in other pictures to hold the board in place during the pour. It works great and could be done for 5 cents worth of strapping instead of $2 of all-thread. It was also faster, I didn't need somebody with a wrench on the other side. I didn't even make plywood washers.
