Hanging Porch Swing From A Beam Held By Joist Hangers One Each End


If I was framing this from scratch, it would go a lot different. But I need to work with what I can get to on this remodel, so looking for any input.

I wish that I could notch the center beam (red color in the photo) into the side wall, or place on top of the current walls, but its not possible.

A porch swing with a max of 800 pounds will hang from it.

I guess I just don't love trusting joist hangers on both ends of a support. I've always built things from the advice of "if all man-made fasteners disappeared, would it still hold?" and this doesn't pass that test.

Thoughts?

Re: Hanging Porch Swing From A Beam Held By Joist Hangers One Each End


wouldn't be so worried about the hangers as i would be the load on the 2x8 beam.

what is the span of the 2x8 & grade of lumber?

span of 2x10's?

and there is nothing wrong with "man made fasteners"....

they are a way of life for us out west and we don't think twice about them.

perhaps different mind set where hardware is not so prevalent in the design or codes.

Probably #2.

Span is only 8 feet on the double 2x10's.

It's an outdoor entrance way.

I was thinking double 2x8's spanning inbetween and the span is only 6 feet.

I can't imagine there would be much deflection there.

You know how it is - when someone ingrains something in your head when you're learning the trade, it sticks with ya.

Just looked in the Simpson catalog, a double 2x8 hanger like a LUS28-2 has an allowable floor load of 1,315 lbs........... they are very strong.

Yep, I pulled out the load table too. (Thank you for checking as well)

Just wanted some reassurance!

Jesus Jenny, the old folks in town would hand the wooden porch swings from the 2x4 porch rafters without a moments concern.

Re: Hanging Porch Swing From A Beam Held By Joist Hangers One Each End


I'd be more concerned about the lack of braces due to a live load on that. Especially swinging.

Re: Hanging Porch Swing From A Beam Held By Joist Hangers One Each End


Definitely needs bracing front to back and side to side.

I have no idea how a swing gives an 800 lb point load in the center instead of 2X 400 lb loads closer to the ends of the beam.

I've done something similar, but went with an a-frame style with 2X12 for the legs and chain to attach to. Even a 2X4 us good enough as a spreader when you attach at what would be your beams over the posts.

I was using 16' long legs, so I used strong backs on 2X4s for them.

Yup, then the 2x4 is only needed to keep the A-frames together and from spreading.

No, bracing the swing structure. braces for lateral movement. We call them knee braces where I come from.

Perhaps my drawing was not very good.

This isn’t a swingset.

I need to install a joist between two walls, in order to support a porch swing.

The walls are solid and they have a double 2x10 beam in both of them.

I’m simply talking about the safest way to attach the joist that will run from Wall A to Wall B and will hold the swing.

My thought was to simply use joist hangers to hold the joist between Wall A and Wall B.

However, I typically prefer to run joists on TOP of the beam for best support, so I wanted to make sure that a joist hanger can not only support the dead load, but also the swinging motion.

Your drawing reflects posts and beams.

Ahh, I gotcha.

So you’re talking about running a knee brace from under the hanger to the joist that’s is holding the swing.

Not neccessary, if those walls are solid. I thought it was just posts and beams. That does however depend on what's holding the walls together.

Just hangers, like Mike says.
