There is a hotel going up next to our office building in Seattle. The GC is currently framing up the restaurant level for the concrete pour and a few of us are debating the purpose of, from our view, look like hundreds of capped metal studs or bolts sticking vertically through the form floor. At first we thought they were anchor points for rebar, but they aren't uniformly spaced and yesterday the guys started laying rebar and haven't been using them. Any ideas what these are? Holes for electrical drops?
Probably for wire or pipes of some kind. @IW17 where you at on this? I’m usually coming in for stairs or doing big ass moment connections. You see these all the time I bet.
They're metal studs, same as Nelson studs on a structural job. Except that while on structural steel they get welded in place, these come pre welded to strips of metal, then each section gets placed on plastic chairs that have a locking bracket to hold them upright, and holes that can be nailed down to the plywood floor forms. They create additional strength around beams and columns, giving the reinforced concrete something to grab ahold of around critical shear points.
@IW17 Are you referring to the rows of studs extending out from the base of the columns? I'm wondering about the white caps, easiest to see in the second picture down by the pipes with the red caps.
I read your initial response going “DAMN he really ONLY does rebar” lol. I figured you saw the studs on the beams when you posted.
