I'm planning on building a home climbing wall in my garage. I'm wondering about the structural integrity of attaching it to the trusses. They are 2x4s, 24" apart, and span about 30 feet.
My wall will be 8' wide by 12' tall at a 45 degree angle (I have 9ft ceilings). Since this is a bit of an aggressive angle I'm concerned about attaching that much weight to my trusses.
If that doesn't seem like it would be alright, how can I modify it to work? I was thinking I could add some 4x4 posts to the each side of the top plate, but I would prefer less intrusive options.
Would I need to reinforce the garage wall too? I can double up the studs if that's necessary
One last question, that original image is using 2x6s for the climbing wall frame, would 2x4s be alright as well? I've seen a bit of both on the internet.
Thanks for any advice.
EDIT: Current Plan
Per most recommendations I shouldn't attach much weight to the trusses. My current plan is to anchor the climbing wall heavily to the garage wall with joists at an angle (like the second picture but beefier).
For attaching the top of the climbing wall to the trusses I'm going to lay a 2x6 across about 6 trusses on top from within the attic and then bolt a 2x6 from within a garage to that one (so the trusses are sandwiched in between), that way I don't need to drill/bolt into the bottom chords at all.
I'll be doing the same thing about halfway between the top of the climbing wall and the garage wall and attach the climbing wall there as well. In that way whatever load is on the bottom chords will be spread out across a larger area.
