Build a pull-up bar setup.

[Stiffan]

Hello!
I'm looking around a bit to figure out the simplest way to build a chin-up bar at home.
What I've thought is the simplest possible. Two beams/poles on each side and a 28mm electro-galvanized steel tube straight through.

My question is as follows: what diameter should these beams be and where can I find them? How can I securely and easily fix them into the ground?

 

[Stiffan]

I can only find building studs in 95x95 and I don't think these will hold?

 

[dsub]

95x95 standing should be enough.

Should the structure be outdoor or indoor, free-standing or anchored?

 

[Stiffan]

The frame will be outdoors standing on the ground. So do you think 95x95 will hold? There are considerable forces when you swing up on the bar. The frame should be anchored in the ground (or what do you mean by freestanding) (the chin-up bar should be stable and not move)

95x95 holds.

 

[Stiffan]

Should these in such a case be cast in place and how do I do this?

You buy ground screws:

Or ready-made plinths:

Depending on the height of the scaffolding and your weight, you may also need diagonal braces for the scaffolding to be fully stable. Another way is to use four plinths/posts.

Does it work with the ground screw for 95x95 plinths? it says that the diameter is 70mm.. And how do I screw this down into the ground? many questions now..

 

[Stiffan]

Or how would it work if you dug a hole, pressed down a pole with concrete, and filled it with gravel?

 

[sblixten]

The weak link will probably be the anchoring in the ground.
Cast sturdy plinths.

Still feels unstable with a plinth that sticks up and that you screw the beam into. Consider that the beam should be at least 2.2m high and then an iron rod over to the next beam which of course should be at the same height, does it hold?

Still feels unstable with a post sticking up and fastening the beam to it. Consider that the beam should be at least 2.2m high and then a metal rod over to the next beam, which of course should be at the same height, will it hold?

Instead, insert 4 pcs of 700mm posts and screw beams between the posts, then place the rod in the middle. Can guarantee that this will be stable.
