Ledger board with engineered trusses (w/ picture)


My contractor installed my ledger board for my deck (just nailed it to the house). Everything that I have read says to lag bolt into the rim joist. We have engineered floor trusses so we do not have a rim joist. I have found a picture online of what our floor trusses look like. Would it be alright to fasten using 2 lag bolts on each truss? ( or should I use carriage bolts like the picture?). WIll either of these methods support the deck? Thanks!

Pretty weak connection. You may want to consider installing a standalone deck.

What do the plans say? The inspector will decide what is right or wrong.

I suggest you ask your contractor s that he will discuss to you what is the best for it. he must know it being the handyman doing such jobs. And what looks in the picture, it looks not strong hold.

Here’s your guidelines, from Fig.13b of this; http://www.lancova.com/deckinfo.pdf

Check with your local B.D. Be sure the exposed threads are equal to the nut thickness, not as pictured, to be safe.

You are correct. A lag or carriage bolt will work. The deck has to bolt to the thick parts of the beam, not the OSB parts. Usually you lag it into the ends of the floor joist if not, to the top and bottom thick parts of the outter beam.
Nails are not considered structualy sound anywhere by any standard. Nailing would be ok if the ledger board for the deck sits on the slab or some other supporting structure.
