Hi

I am looking to hang some gymnastic rings from the exposed beams/joists in my garage (sorry I am not clued up on the beam/joist/rafter terminology) but am slightly concerned about how much weight the roof will support.
I'll try to explain the setup as best as I can as I can't upload a drawing at the moment). I live in a standard semi, with the garage attached to the side with a sloping roof. There are diagonal supports that sit on top of the external wall and run up to the house wall and rest of a piece of timber that has been drilled into the wall. There is also a single beam that runs the length of the garage, supported by the front and rear walls, that the diagonals rest on about midway.
I had planned to simply loop the straps the rings come with over this single middle beam (that runs lengthways) and then that would be it but I am wondering if I need to give it additional bracing or something? Previously I had a punch bag hanging in the same way and it used to make the whole structure shake so ideally I am looking for something more substantial. I had considered attaching a piece of wood across several of the diagonal pieces to spread the load but my main concern is that they aren't supported very well themselves. As it stands most of the support seems to come from the external wall that they rest on, as at the other corner they are sitting on a worringly thin piece of wood that is bolted into the wall - so obviously I don't want to risk pulling the whole roof down.

I apologise for my vague description but hopefully someone out there will understand the type of setup I have. By the way I weigh roughly 70kgs & the rings weigh virtually nothing but I'm guessing there will be additional stress put on the structure when performing the swings etc.

Thanks

Can you post a picture of the rings themselves?

We really need to know how they mount.

They are basically two rings with straps that go through them and then have the clasp to secure them in place. I had planned to literally chuck them over the main middle beam and hang from their as I am reluctant to start drilling and hanging them from an eye etc.
I noticed yesterday that the middle beam - that runs the length of the garage isn't completely vertical and is slanted so that the diagonals sit flush to it. I know that most of the strength of the beams comes from the vertical direction so I am wondering if this might significantly reduce the strength?
I'll try and take some proper pictures at the weekend if need be?
