concrete slab inserts sizes
concrete slab inserts sizes
(OP)
hi
i am a duct designer and i want to specify hanger insert sizes to be embeded in a 7 1/2" slab on 3" metal deck. i need to use 3/8" and 1/2" threaded rod droped thru the deck before the pour. is there a reference standard that will tell me accepable sizing of the upper attachment "insert". the duct reference SMACNA shows typical configurations for strap and rod but no sizes.
thanks

RE: concrete slab inserts sizes
Are you sure you want to pre-install? I've seen a few buildings with post installed anchors right next to the pre-installed anchors.
