Rim Joist made of multiple segments?!?


Just so we are clear I'm taking about the outer most joist than runs parallel to the floor joists. Seems that band and rim and used interchangibly. Anyway, I walk by a house down the street being built. The framer used scrap floor joist pieces about ~5 foot in length to go about 18-20 feet. They are just butted up end to end and aren't doubled up. It appears the only thing holding them together looks like the sill plate and the decking. Seems like this is against code. Anyone know?

Not against any code I am aware of.

Why would this be a problem to you?

Just seemed a little unsafe since it will be support a load bearing wall...

Not the preferred method, but probably a non issue especially if they run the plywood down over the rim.

I thought rim running parallel to the joist needed to be doubled.

It' been a while.

outer rim joists parallel with all other joists usually need to doubled for the wall that sits above it.

Can you back this up with some data?

I have framed for 25 years and never heard that done.

non gable load bearing wall would need the double under it, gable wall not so much...

Incorrect. What code book did you get that from?

my own code book, plus architectural plans I've followed over time. ha ha, I can hear the electrician cussing right now because of the double band under the wall he needs to drill through to run the wire.

I think the rest of us who follow standard codes will continue to do what we do. If you want to waste labor/materials, screw up mechanical subs,insulation, etc. More power to you.

Just remembered the exact reasoning for doubling up on those joist rim bands. had homeowners change up stuff a few times to upper floor plans so point loads are required, and multiple blocking as well in some cases and what a pain in the ..,, to crawl under and add wood later

I think a double band thrown in could be quicker than framing 14 1/2"s 16" On Center along the outer band joist bay. just have to notch out for the sill plate bolts on the inner band and done, homeowners can change plans and add beams wherever they want.
