Securing a pullup bar to underlying brick wall that has had an insulated stud wall built over it?

I have a garage wall which used to be brick that has been converted.

It now has a stud wall (4 by 2 treated timber) with 10cm insulation in between.

This has a plasterboard and normal plastering for finish.

Is there a way I can fix something through to the underlying brick when there is effectively a 10cm gap between the studs and the brick wall?

My thinking is whatever screw/bolt I use will snap with such a big gap.

Any ideas or is this a non starter? Thanks
 
It's doable, plenty of ways to crack this egg, one way is fixing say a 25mm thick plywood sheet (it would be a minimum length to allow it to be able to fix to at least three studs and as high as it needed to be) and you could mount that to the face of the plasterboard with fixings (resin anchors probably) that go through the studs and are embedded in the brick. Then bolt your pull up bar to the plywood with bolts inserted into the rear of the plywood with holes cut in the plywood for the bolt heads. There are a few other ways to do it I daresay. Of course you can get a floor mounted one pretty cheap.
 
You could span two studs with thick ply and heavy brackets to ceiling timbers effective hanging you pull bars ( and your weight) from the ceiling timbers as well as the studs.

My main issue is that from what I can see, this particular stud wall's top plate doesn't seem to be secured to anything. I suspect it has been cut to size and forced into the gap. The bottom is of course secured to the ground but I'm worried about the pullup bar effectively pulling the top out. The other walls have the top/head frame secured to a beam.

The studs themselves aren't attached to the bricks either. It's a false wall with around a 5cm gap from the studs.

Does this change anything?

Thanks that's something I haven't come across before. Any pointers as to how this impacts the load distribution?
 
this is the wall in question. No obvious fixings for the top frame that I can see

This is the finished wall (with crappy pullup station which I am keen on removing!)

Surely the top plate (the horizontal batten at the top) is fixed to the trusses above? Anyway you would be fixing through the studs into the brick. Is there a gap behind the studs and the brick do you know or are they hard up against the brick?

That was my thinking too but from what little I can see by crawling into the loft space there's nothing obvious attaching it to the trusses. I might well be wrong!

There is a small gap from the studs to the brick (about 5cm).

Do you suggest screwing through the studs into the brick? Will the 5cm gap affect the integrity of the screw?

Looks ideal , ply across the 3 studs, then heavy angle brackets from ply to the 2 trusses above.

Sounds like a good plan.

The board will need to be fairly close to the ceiling to get the angle brackets to fix to the trusses.

The pullup bar will need a good 20cm clearance from the ceiling - will having it fixed to the lower end of the board be an issue?

Board tight to ceiling , bar can then be fitted anywhere on the ply, bigger the ply the better .
