Joist hanger on support beam

[Kaizen]

Building a mezzanine/loft in the garage and ran into something I’m not sure on. I’m using joist hangers to support 2x6s. Two locations where they land on the support posts. Is this ok to mount or should they be on the side of the post?

I don’t see any issue with mounting the hangers on the post, it’s really no different than mounting them on the rim board.

Either way. The joist connection will be superior on the rim joist, extremely so if you nail to the side of the post, but it's gonna hold up either way.

Thanks will do. Appreciate your help

Spacing between joists is really more about the decking being used and the load put on it.
So theoretically, the spacing maynot be that critical.

Then again, you could just move the post a bit one way or the other. Don't think I've ever seen a joist attached to a post in that particular scenario; and I think if it were being inspected (...say if it were a deck) I don't think it would pass muster.

How is attaching the joist to the post any different than the ledger in terms of weight bearing, strength, and overall end result vs attaching it to the ledger board?

I would be more concerned about the ledger board. You should using structural screws into every stud in that back wall.

Grain direction is different but biggest issue in my mind is how many nails or screws are going into one general area. I have seen tops of post with to many nails start splitting apart. I would personally use structural screws and pilot drill the holes

I get the grain direction, but the ledger is bearing the load horizontally. The post is carrying the load vertically.

Pilot holes for structural screws makes sense for sure.

Yup planning two at each wall stud. Probably long like 4” as I have 5/8 ply that will get two inches into studs.
What thickness size would you recommend? Don’t want them to fail because too thin

Plenty of meat in the 6x6 I used. Even have plenty of room for bolts. They sure are heavy though. Dropped it on my toe.

How do you know he didn't.

Using these screws. Not the perfect solution but all I have local. My little dewalt impact is going to town.
Still have to put bolts at posts and two posts at ends but hard work is done. Some info on the build.
Cost about 800 (10/1/2020)
36x4’ platform. 7.6 foot high surface. Double 2x10 rim joist staggered. 2x6 floor joists 16 on center. 6x6 pt posts 12 ‘ apart on metal brackets anchored to concrete and bolted to rim with half inch bolts
3/4 ply
Solo build of course. About 16 hours as I’m no framer

I would want to make sure that any hardware used on a PT board be rated for PT use. Hanger and screws/nails.

The GRK RSS are structural screws and rated for pressure treated/outdoor use. So you're good.

You're right you need to use the fasteners Simpson specifies (or whoever makes the hangers used).

But from what I've seen of Kaizen's projects I'm pretty sure he know this.

I can't answer or add any advice in regards to your lift build.

But I notice what I think is GM A body on a rotisserie? What car is that? I want to say its a 69 Cutlass with the typical rot on the cowl.

Good point. Not sure if the hanger is galvanized. Nails used are as well as the bolts. I have non pt 4x4s for the end posts so really just the two posts are pt.

Edit just checked looks like all Simpson ones at my Hd are galvanized

Yup 69 chevelle convertible. Large part of the clutter are parts for that. Replaced just about everything on it. Had it in two pieces to replace the floor. Really hoping I can find time this winter to get back in it and just have some fun.

I been there done that with my Cutlass. Lots of work. My cowl was so bad I got a a nice one out of a car in Arizona. In hindsight I should have put a Chevelle cowl in, That would have messed up people looking at my car and I could have gotten plenty of parts for it, dash pad, gauges etc cheaper.

In any event good luck with your build(s).

You might find a lower price on a nearly equivalent joist hanger, but IMHO, there is no equal to Simpson. Their Catalog technical information is outstanding.
