How to mount a deck ledger on a Larsen truss wall?
We need to mount a 2x8 pressure-treated deck ledger to a conventionally framed wall that has a 8" larsen truss attached to it.
The frame is as such: 2x10 rim joist bearing upon 2x6 mudsill, 5/8" T&G OSB, 8" Larsen truss, 1x4 cross-strap, Tyvek. The deck ledger will be mounted at the same elevation as the rim joist.
The supported length of the deck is not too great, between 5-8'. I would like to attach the ledger on the same plane as th 1x4 strapping and not directly against the OSB.
Does anyone know of a detail for this? i been trying to come up with a detail where the ledger is bolted to the rim joist with long carriage bolts with squash blocks preventing the trusses from getting crushed, but I would need an elegant way of keeping the ledger spaced off the Tyvek to allow for drainage, etc.
We plan on using 1/4"-3/8" cedar lathe for the rainscreen.
Thanks again, gba.
