Ledger strip nailing. OK or not.

[Joe Funderburk, CMI]

Terminx replaced many floor joists in this crawl space. They added the ledger strip for support. Most I see have 3 nails beneath each joist. Is there any specific c-de that requires a certain nailing pattern? I sure don't see it in the IRC.

[Bruce A. King]

It looks like that ledger is bearing right on the curtain wall which is fine as is. Somewhere the code states 3 nails under each joist but that would be a ledger without additional support in my opinion.

[Bob Elliott]

Since when do we use nails in masonry?

[Joe Funderburk, CMI]

It's nailed to the rim joist. Just a tad sits on the crawl space wall, as Bruce mentioned.

[Bob Elliott]

Sorry
Flying through and saw what appeared to be a ledger board nailed in to CMU.

[Jeffery L. Haynes]

R502.6 deals with bearing of joist.....I don't have my ICC book with me to actually verify the 3 nails under each joist however that is the case with code inspectors.

The information you asked for is in the 2009 IRC TABLE R602.3(1) FASTENER SCHEDULE FOR STRUCTURAL MEMBERS:

Ledger strip supporting joists or rafters 3-16d (3 1/ 2" x 0.135") At each joist or rafter.

[Marcel R. Cyr]

This may help.

Ledger Strip to Beam (face-nailed)3- 16d each joist

What is the condition of the base plate? This looks like they nailed a furring strip to it to conceal it. I may be off base but there is not enough to go on with those photos. The bearing on the "ledger" is inadequate.

As I recall, there wasn't a base plate. You often don't see them around here. This house had large portions of the band sill and floor joists replaced, along with the ledger.

Thanks for everyone's feedback.

So, in my humble opinion, that horizontal 2x2 can do nothing structural. So, the nailing doesn't matter. Maybe my California up-bringing.

The 2x2 holds up the floor joists so the nailing is very important. In the posted pictures it has substandard nailing but has some extra backup support by bearing on the brick. Its not perfect but not going anywhere. No need to write it up but ok to do so if you choose.

A 2x2 holds up a floor joist?????I guess building outside of California really is....different. I have never seen a 2x2 used for anything other than trim.

IRC R502.6.2 Joist framing. Joists framing into the side of a
wood girder shall be supported by approved framing
anchors or on ledger strips not less than nominal 2 inches by
2 inches (51 mm by 51 mm).

Done that way here 90% of the time.

I don't doubt that is a acceptible way of building in your area, just never have seen it. Being new to this site, I need to keep in mind the differences from state to state. Building has changed so much here. Now homes are built to commercial standards. Thats why they made a pnumatic "tico" hardware nail gun.
