We recently poured the second level walls of a three level home. In doing so we included the Simpson Strongtie brackets for the third level floor system. There is a 1.33' floor ceiling height change. I stopped the lower Simpson brackets 4' before I should have.
How can I support the double 2x10 ledger where I missed putting in the bracket? I want to avoid putting a wall under the end of the ledger. |

As "They" say - It happens... I'm a big fan of the Simpson product line of Anchor systems and Adhesives/fasteners. They make an adhesive product that is I.B.C. approved, called the SET-XP that is used for dowling and anchoring applications. They also make what they call the Simpson Strong-Bolt Wedge Anchor, and the Titen HD Screw Anchor. Perhaps you could select which is best for your project, and then: A- Mark out the height you need to be at, and remove a band of foam from the wall equal to the depth of the ledger board you are using(10 inches as noted) and then simply fasten to the wall. B- Do the same steps as above, but instead use angle-iron ( the stuff used to carry the load for brick ledges) and fasten accordingly. C- I know that the ICF Connect system also has a method for hanging the ledger after the fact as well- but I have no persononal experience of using them that way. - Hope that helps. All the best of luck to 'ya ... Take care,
Chris Kerr

You might just need some through-bolts to attach the ledger to the wall. It would depend on the load and exactly what the detail looks like. But I'm pretty sure there is a better way than building a wall. JDC |

I need to carry 2520# for the 3.5'. I would like a fastener that, in case I am questioned by the building inspector, I could prove is adequate. |

Brad Why don't you just remove the foam from behind the rim joist area drill in and set anchors or threaded rod with epoxy and pour concrete in to cut out foam area to grout in bolts as if you used anchor bolts. use the engineering for anchor bolts. |

I didn't want to remove all the insulation for the 2x10 and I want to be able to prove that it will support the 1005# per lf of live and dead.
Should I screw the ledger half of the Simpson to the 2.5" thick lumber I bolt to the concrete? I will have 5.5" from the end of truss to the concrete. |

why don't you just cut a slot for the ICFLC or 2 slots for the new style then epoxy them in like a bolt |

Ed, I had not thought of that, but I would need an engineer to sign-off on that. I just got back from Menards with some 5.5"x.5" Red Heads and Powers fasteners. |

I will use the RedHeads and return the Powers, the Redheads documented their strength better. We will use 'em in the morning.
Thanks for the help. |

Here is an idea:
Take a piece of steel pipe with an ID just a little larger than your anchor bolts. Cut two pieces the same length as your foam is deep, i.e. 2.5" or so. Then get a piece of 1/4" x 4" plate steel and cut to this same dimension. Now weld the plate between the pipe sections. Now cut out foam to accommodate this standoff and set your anchor bolts at the center-to-center hole distance between the pipe sections so that the pipe will slip over the anchor bolts.
This will allow the load from the ledger to be transferred directly to the concrete without placing a bending moment on the anchor bolts. |

When you say anchor bolts, do you mean the wedge anchors?
But I need to fix this, this morning, so I will be removing all the EPS were the ledger goes. |
