I’m putting in a steel post in a basement supporting a 16′ doubled microlam beam (1 3/4 x 7 1/2 doubled) which is supported on each end by a block wall. I’m placing the post in the center cutting a 2’x2′ hole in the floor and setting a pad. (in case your wondering this post is not one of those grey ones with the holes in it for height adj.)
My question is how deep does the pad need to be and does it need any rebar? Also the tubular steel post has a welded plate on the bottom with two holes at each end for bolts. Since the post will be set below the floor level (for height reasons) if I pour the pad 6″ to 8″ below floor level should I bolt the post to the pad, and finish the concrete to floor level, or just set the post on the pad with no bolts, and finish the concrete to the floor level?
If using no bolts, will the concrete for the finish pour adhere to the pad form the first pour?
Thanks
Tony
