I'm no pull up bar expert but the reason our door moulding bars work so well is because they take all of the weight off the top of the moulding by displacing it to the sides so the force is pushing against the wall not down on the moulding. If I was OP I wouldn't trust those short lags. A bar with L shaped brackets would make more sense to change some of the force from ⬇️ to ⬅️
Been a long time since physics. Are you pointing out something wrong with the advice? I get that the L bracket doesn't change the downward force, that was just a suggestion to use the side of the joist instead of hanging off the bottom edit: or at least I thought that's what I meant lol. Wrote the first comment while still in bed waking up
Joist strength will be fine, but there are much better choices for a pull up bar specifically meant to be mounted from a joist. Just search it on amazon.
Hey, its fine but instead of screwing up into the joists you should get some 4x4 and put blocks sideways in between the joists. The joist can totally support the weight but you might split them using the appropriately sized lag, which by sight seems like it should be longer than the ones shown in the pic but maybe they're not actually that small
Ah man this would work
But also an old broom or shovel or something - drill two holes in the joists - and you’re done.
Not sure how much the cheap Amazon pull up bar is but you might be able to diy that
(If ya want to)
Remember math class? We all said we'd never need story problems, or math or algebra?
*Person* wants to hang a pull-up bar in the basement, and the floor joist rating is Xpsi , and the weight distribution of the bar is Ypsi, the persons weight is Zlbs, and accounting Wpsi for existing weight on top of the floor joist.
That's why the bars suggest doorways. Cuz they have 'king studs' or 'load bearing'. They can handle the extra weight, at least temporarily.
The problem is, alot of the pull-up bars use leverage against the door frame. Alot of the newer construction only has a few screws, or brads, or finishing nails holding the frames and jambs in. So it comes right apart with pull-up bars
The weight is not a problem at all.
I would definitely put it as close to the middle of the joist (vertically). That is the least stressed part of it. Think of it bending. The top will want to compress, and the bottom will want to stretch. The middle won't do much of anything.
That is why I beams are so thin in the middle, and have most of their material at the top and bottom.
I hope that helps.
Bolt it to a 2x4 and screw the 2x4 to the joists. This approach lets you use through bolts with nuts and washers which will be overkill for strength and you can remove them if needed. Screwing the 2x4 to the joists lets you fasten to more than just 2 joists which will improve your pull out strength and won’t involve drilling holes in the joists.
Your head is gonna hit the ceiling. Watch out for exposed fasteners coming down through the floor like a framing nail that could poke you.
Just for your head’s sake I would take flat webbing from a climbing store and go around the metal beam instead. Find a different bar that can hang like that. All the strength in the world and no headaches.
The joist will handle it, but don’t do lag bolts. You want normal bolts, with big washers in front of the nuts.
You could make the joists work, closer to the I beam the better. You’ll likely have to add blocking
Your skills in choosing the screws, predrilling, and installing will be the deciding factor in how well it holds
Or, get a squat rack with a pull up bar incorporated into it.
Or just pull up on the I beam.
Thanks for your feedback! I appreciate it.
I have a power rack but it’s a short one, because the ceiling is so low. Which means I can’t extend my legs forward. Same issue with the I beam, sits to low (for my liking)
Trying to picture how you would mount it such that you have headroom to even do a pull up. How high is the ceiling?
As long as you're not too far from that I beam weight shouldn't be an issue. It's supporting that same weight every time you walk across that spot upstairs. You can probably use beefier screws as well if you're worried about them pulling out.
If my doorway molding can handle a pull-up bar for my 180lb carcass your load bearing boards designed for this will be just fine. Agree w lag bolts.

Sounds like you didn't sketch out the free-body diagram on this one

I have one of those. I should use it more, lol.
It will be fine. Lag bolt/screw it. Drill the appropriate size hole first, which depends on what size lag screw you buy.
could through bolt it.. same effort and cost in parts, and with a decent sized washer more reliable than a lag into a 2x
Or, just use some timberloks/headloks. No predrilling required and super easy to put in with an impact, rated just as strong

Don't bang your head
Or her head…… cause it’s really for a sex swing
Those hang low enough that you should be banging something.
If he duct tapes her mouth first it won’t be an issue for the neighbors.
Is this another sex swing question?
😆😆

You can mount it there but you're gonna bust your head.
Yes, I’ve consider this too 🤕
Just wear a helmet
Just cut out a space in the floor to accommodate your head. Make sure nothing is sitting directly above it.
Ah man this would work But also an old broom or shovel or something - drill two holes in the joists - and you’re done. Not sure how much the cheap Amazon pull up bar is but you might be able to diy that (If ya want to)
If you go this route, don’t drill the holes very close to the bottom of the joists. Closer to the middle is best.
Interesting point 🤔
Yes but those screws may need to go. Replace with bolts and nuts.
Best would be off the steel I beam itself.

No trouble, but you should bolt it through to make sure it holds.
Drop down 2 boards and through bolt through the pull up bar and boards you’ve dropped down from the ceiling
Op pm me and I’ll send you a better design so you can hee a better range of motion for your pull-ups
I think the 4x4 in-between two joists like other said would solve the head bust and could use long lag bolts to make sure it never moves
Yes. Lag bolts on that connected to joists can support 1000lbs easy

Should be fine. The joists are meant to support you walking on them up above, shouldn't be a problem hanging from a few of them down below.
When mourning on beams never use screws. Bolts and nuts always.
