pull-up bar diy

[marruggio]

approached to the entrance of the shed 2.50 meters wide 4 meters high, I have on one side a beam at H 160mm, on the opposite side a 100 mm diameter tube 3 mm thick, I could use these as upright poles, I would have a bar crossbar scaffolding carpentry iron pipe 48 mm diameter 3 meters long
but as I fix them, I should make it removable, if I have to enter a vehicle or a mechanical means I have to weld removable supports. some idea?

to be fixed to the wall or on the portal of a door, sorry if I have not been more precise thanks

As always, we need more information. Is this to mount in a doorway, on the wall, add to an existing weight machine setup?
