I am putting in a hanging beam in my ranch style house. To replace a load bearing center wall. The only load on the wall is ceiling load. It is a hip roof. The lumber in all rough cut. They are 2x6 ceiling joist that are spliced on top of the wall. So I need a hanger 4"x at least 12" tall. I can't find any hangers like this. Or could I use long hurricane ties?

2You're asking major questions with no information... how about a few pictures??– JACKJan 20, 2021 at 2:11

Ceiling load might not seem like much, but depending on weather - wind/hurricanes that try to tear off the roof or snow that weighs down the roof, it can be quite a bit. Location (country/state/region) may be relevant.– manassehkatz-Moving 2 CodidactJan 20, 2021 at 2:22

1Are those 2x6 ceiling joists part of a truss? We need a pic. Click on the icon in your question to add a pic.– Lee SamJan 20, 2021 at 3:17

1Hard to tell from your description what you need. Do you have a sketch or a picture? Have you looked through the Simpson catalogue?– SteveShJan 20, 2021 at 3:18

2The 2x6 and not part of a truss. It is a rafter hip roof with rough cut lumber. No vertical supports in attic. The 2x6 ceiling joist go from exterior wall to exterior wall and sit on interior wall where there is a splice in center. I want to put a beam above ceiling joist and hang them in attic. Then remove the wall. I know the beam size for the load. Just can't find a hanger that will take 4 inch wide joist. I don't have a picture.– McboydJan 20, 2021 at 3:32

I’ve never seen a hanger with those design requirements. I like the idea of using a hanger that allows the joists to “sit” in a hanger’s pocket rather than using straps to tie the joists up to the beam. However.....
However, installing such a hanger under joists without damaging the drywall, would be difficult.
I’d try a strap such as Simpson’s HTSQ twist strap.
https://www.strongtie.com/twiststraps_specialtystraps/htsq_strap/p/htsq.
If the joists span half the width of the building (16’) and only supports a ceiling load, then the load on each joists is:
Joists = 2 psf (per square foot)
Plaster = 8-10 psf (depending on type)
Total load = 12 psf x 16’ x 1.33 (to get to 16” oc)
For a total load on each joist = 255 lbs. / 2 (to get load at each end = 128 lbs.
As you can see, these straps are rated up to 720 lbs. depending on the species and grade for uplift. (Your resistance is the reverse of uplift, but is the same principle, but upside down. )
Now, the shortest strap is 16” long, which means 8” should be on each member. However, your joists are 6” tall so they won’t have the intended “cover”. But, your load is so much smaller than the maximum the straps could support, that I’m sure they’ll be fine.
You also have one more issue: If your new beam deflects (sags) at all, then the joists will sag and the ceiling will crack. Plaster is notorious for cracking with minimal deflection.
I have not allowed weight for anything in the attic, (like insulation, light fixtures, etc.)

I planed on using 2- 2x14 lvls. They have a load of 254 for L/360 per beam. I figured it should be about 1/4 inch of deflection across the 16'. I also used 20PSF as my load. Thanks– McboydJan 20, 2021 at 10:59
