Door pull-up bar without door frame

[Belix]

Hi folks
Forgive me, I'm far from a DIY fundy...and i'm keen not to injure myself, even though I feel rather foolish about posting for such a simple project,

I've had one of those verimark door frame pull up bars that hooks behind the door frame. Unfortunately our house either has doors without a frame, or a wooden frame on the opposite side to the opening, meaning the door is in the way and I cannot use it.

I wanted to mount a strip of wood on the opposite side to act as the frame support.
Given I cannot go out shopping, I've found a piece of 3cm x 2cm x 70cm pine. Granted pine is not the best wood available but that's what I have.
I also can only find two fixtures, a pair of SX 12x60 wallplugs and 7cm x 7mm diameter screws (bolts?).

- Will just the two screws be enough to support 80kg? The force would only be downwards, so I think the wallplugs should be sufficient rather than expansion bolts.
- Since the screws are quite big, will using them significantly compromise the strength of the pine strip?
- I'm assuming there should be a lintel somewhere above the door, should I aim to drill into it, or above it? Assuming I have a drill bit strong enough to bite into the lintel anyway...
- Anything else I'm not thinking of?

The screws are probably more than enough provided the plaster is not soft - the pull-up bar will push down on the strip so shouldn't cause them to pull out the wall anyway. Just bear in mind that there's probably a lintol (about brick height) across the top of the doorframe under that plaster, so mount the strip a tiny bit higher than that otherwise you'll hit concrete...

My one concern is the 7mm thickness of your pine strip. No skirting lying around? Perhaps double up on that thickness wise if you can.

LOL, a bit late for that
That one requires more robust bolts / screws and plugs because the weight is projected out from the frame and it will put outward pressure on the top bolts. Nice bar though.

dunno hey.. i'd go with those expanding bolts.. i know those can hold a 40kg load each

I've seen TV mounts with more and bigger screws so I would be cautious.

I wouldn't trust those screws and plugs to hold anything up. Get decent anchor bolts.

What's behind the plaster? Bricks?

I have one of these from Decathlon which I would recommend over one of those that hang on the door frame.

With the expanding door bars, you can vary the height of the bar in the door so they are very versatile. As well as pullups and leg/knee raises you can do front dips, head knocker dips, incline pushups, hamstring curls, anchor your feet for situps etc.

They're nice for incline (hand raised) push-ups for people who are building up strength to a full pushup - drop the bar to increase intensity and also promotes the correct form better than a knee pushup.

Thanks, don't have the space, need it to be removable when not in use, even if I could get one before our 21 days are over.

Its one of these jobbies

No fear, the pine strip is 2cm thick by 3cm high.

True but there is no cantilever like a TV stand. The pine strip would be pulled downwards, and pushed into the wall as the pine strip is slightly thicker than the thickness of the black top bar on the gym

Don't have much worry on the bolts breaking - the two holding the bottom bar on the gym itself are half the thickness. I assume there is brick behind the plaster, not sure.

Nothing wrong with those bolts.
If your weight is such that you break those then pull-ups aren't your thing

But how are you going to get your muscle up on that without tw@tting your head on the knotty pine?

His head isn't that big I'm sure LMAO

Muscle up, not pull up ...

OP, those bolts will hold fine
