Been looking for joist hangers / brackets to connect a future swing set to an existing wooden  structure.

Found these online and I think they look lovely.

Anyone with experience using these got any wisdom to share? If not any and all advice welcome.

 The plan was to use this kind of joist to connect the framing (two 14x14cm posts 1.1mtr in ground with concrete and one beam with the same diameter, plus two buttresses) with the existing structure. The beam that would connect the two would also get buttressed

Maybe, I'll use a variation to connect the framing for the swing itself too, but I'm holding off till I get some advice from more experienced folk here.

I've put a picture up and circled in red where I plan to use the hangers. The swing will be where the guy is standing, plus another one on the other side of the long beam. I know the posts are all drawn as standing on concrete foots, but only the blue highlighted posts are. The two newer ones are straight in the ground (with coating and concrete). Buttresses not pictured. The existing frame is also carrying a roof that i have not pictured as it got in the way of the view.

Anyway here's the hanger I'm talking about, specifically the one to connect to the existing structure.
