Temporary W8x15 connection to HSS 12x4
Temporary W8x15 connection to HSS 12x4
(OP)
Question:
California Highschool remodel:
I need to design an attachment of a temporary safety beam (W8x15) between two HSS 12x4 (flat side)columns for elevator installation. I was thinking of using a WT at each end to bolt into the web of the wide flange. After elevator installation, the saftey beam and the WT have to be removed to attach the elevator guide rails.
Note: the back of HSS columns will be framed into existing wall. Saftey beam is temporary and has to be removed because of insufficient height clearance in existing structure.
My question: Any suggestions on how to attach the WT to the HSS column without going THROUGH the HSS column with a bolt? Since this is a temporary installation, I want to avoid welding. Remember, I have to deal with DSA approval...

twinnell: Thanks for the suggestion. I could weld a plate however do I want to do that for a temporary condition where the plate would then have to be removed after elevator installation? I need to use that HSS for elevator guide rail support. I'm new at this so I'm not sure if this is done often...

PMR06 and twinnell: Thanks for your input as well.

just curious, are you letting friction to do the work? I guess this is a work area and sometimes the vibration from the moving equipments can loosen the bolts.
Figglet,
How about, having just one size samller tube to fit snug into the HSS, which means the smaller tube will be able to slide in and out. Just connect the wide flange to this smaller HSS. When done, just slide the system out from the permanent HSS. You can have a slidable pin thru both the tubes to provide bearing.
