Avoiding Joist Hangers? – GreenBuildingAdvisor

I’m working on a 12′ x 16′ floor assembly which will rest on 6 helical piers (3 on each long side). The plan calls for 2×12 rims and joists, 24″ o.c., sheathed top and bottom, insulated with rigid and Rockwool batts.

Can I avoid joist hangers by adding a treated 2×6 (laying flat) between the pier L-brackets and the assembly? The idea is to rely on both end-nailing the joists and making use of the 2 1/2 ledge provided by the 2×6.

Or maybe a 2×4 instead, which would give me a 1 1/2″ ledge?
