I'm building a lumber-framed office inside a commercial warehouse. It's essentially an 8' x 30' x 9' box with a ceiling and "second floor" made of 2x6" joists, with 2x6" rim joists resting on top of the two 2x4" walls. Note that the second floor will only be used for light storage.
Because one wall of the office is up against the wall of the warehouse, I can't end-nail the joists. I could toe-nail the joists, but I want to use metal hangers instead. Is there any problem with doing do, even though the rim joist and the hangers will be resting on the top plate?
The back wall of the building is a decorative cinder block. I’ll anchor the top of my walls to the back wall.
The front wall is large steel studs. I bolted the top of the outer wall to one of those studs (although it was out of plumb, so there's about a 1" gap at the bottom).
I’ll bolt the inner wall, too, but haven't gotten to it yet (have to find the stud behind it and drill, then use some kind of toggle):
I'm tying the rim joists to the top plate with Simpson TA9ZKT staircase angles every 5':
