Connecting Angle to Beam/Joist with C-Clamp
Connecting Angle to Beam/Joist with C-Clamp
(OP)
Hello, long time lurker and this is my first post. During a walkthrough of a new building nearing completion, I noticed the supports for an HVAC unit (2 angles) were connected to the flange of an I-beam and a steel joist with beam clamps (C-clamp?). It is my understanding that these are used to attach equipment to the flange of supporting members, but the contractor thinks they can be used to connect steel elements (as opposed to welding/bolting).

Is there anywhere in IBC or AISC that specifically addresses this? It seems common sense to me, but apparently not others.

1) Clamps might come off as a result of vibration or folks messing with them.
2) When clamps come off, the mechanical unit could squash some poor bastard.
3) KootK not comfy with the implied liability. Perhaps Joe Builder would be willing to take it on?
4) No? Too bad, so sad.
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

The largest risk in my mind is that vibrations loosen the screw over time.

Ultimately, we have to provide our own CO, so I'll just say no until they fix it.
