high point load on roof deck
we have a situation where high point loads have to be supported by roof deck. i am proposing number of steel members but it looks crouded. is it possible for roof deck to support point load of 4000 lbs every 5ft spacing. these are chilled water filled pipes.
here is link to the pipe support system for idea.
i doubt that 1.5" 22 ga metal roof deck can support that kind of load.
why not locate the legs directly over the supporting roof members? if you are running parallel to the supporting members that space your supports to sit directly over the supporting roof
how about putting a beam that will span with the pipe above the roof? maybe put a support somewhere where needed.
never, but never question engineer's judgement
thanks.
we can negotiate for prefab pipe support to located at framing
you need to cut it through and seal around it.
never, but never question engineer's judgement
or use a non-shrink grout above and under the deck, and above the lower support. you may need an extra steel plate above the lower supportto support the grout layer.
still sounds like a lot more work than just adding in the extra steel beams.
