Hanger for corner joist installation


Here's what my roof framing looks like for a shed style roof, 1.25:12 slope:

That's a 3' overhang. The Rim board there is actually structural as the header you see is in the same plane as the roof I-Joists. It says triple I-Joists, but I redid the calcs and it will likely be a single (big) I-Joist.

So, my question is how to attach that I-Joist to the rim in the circle? For the one above the beam I'll just use an upside down joist hanger skewed 45 degrees. This one dies into a corner though and I've not seen a joist hanger that can be mounted in a corner. I'm not sure how you would even swing a hammer in there. I could end nail it, but it is structural, and it's an I-Joist, so there ain't a whole lot of meat there to end nail into.

Any thoughts?

Sorry, quick read but no idea what you have. I don't see a low pitch shed roof in your drawing. Looks like a hip maybe.

I'll wait to see what others add.

Re: Hanger for corner joist installation


I consulted with the engineer on this. He sent me this:

I looked up the specs on the LS90 and they can indeed be bent to 135 degrees, but for the life of me I have no idea how I'm going to install those? Any ideas. It just doesnt seem possible to get a screwgun in that tight space to screw down the #10 screws. How does Simpson expect people to install these clips?

Ask for a change.

Re: Hanger for corner joist installation


That's awesome! Is it OK for the new members to be simple dimensional lumber (maybe 2x10) even though they're sistering to engineered lumber (I-Joist and LVL on fascia).

That could only be answered by your engineer. But likely he’ll say no v

Write it in your own drawing with 2x10 or 2x 12 and send it to him and see if he agrees. I would think he will take it like that.
