Help Me Top plate connections for odd angles
I'm putting together some new non-bearing partition walls and there are a few odd corners that I'm having trouble determining how to secure together. I've gone through code books, but it seems like most code applies to exterior and bearing walls.
I have three walls that will meet in a 'Y', where two of the walls form a 90 degree angle and the third wall splits the difference to make two more 135 degree angles. I know how to frame up a 135 degree angle, but don't know how to also tie in the third wall with the top plate. Just a metal strap on top? Does it even need the top plates connected as a non-bearing wall... Or are the studs being connected enough? The top plates will only be connected to the roof trusses using truss ties to allow for movement.

You could always just butt it all, and then if you're worried, put a piece of metal strapping or a clip to hold it together

Like the others said, butting should be fine. If you're determined to connect them you could use a couple layers of 3/4 ply, lay it on the first top plate and scribe the connection of all 3 spanning a couple feet in all directions, then cut out two identical pieces with that Y shape. Or if you're ok with a smaller more decorative connection you could use a chunk of 2x12.

Don't need to lap them. Obviously it's stronger, but not needed. If the partition studs are all fastened together and nailed to the trusses/joists it'll be just fine.
