Unless you have substandard concrete, quality anchors do not pull out./QUOTE]
That is my concern, I don't trust the concrete, it was poured buy who knows who way before I was born, and has cracks.
Well, I'd cut the concrete before I installed the steel plate (you have looked at the price of steel, correct?) But that, of course, is your call.
Ignatz - that is an interesting looking anchor. Like I said, I've only glued studs, but as long as the glue's shear strength is there then I can't see why those would not be excellent.
I will cut the concrete, go way deeper, and probably do a "Bell Bottom" down several feet. Tie into the existing concrete with lots of rebar, and then embed 3/4" steel plate with Nelson Studs welded to the bottom to tie the plate in with the concrete. I want to be able to add additional holes threaded into steel later, using a mag drill and tap instead of concrete and anchors.
See post #729. I am doing something similar, but I have a piece of 3/4 plate, 16"x48". I can drill and tap anywhere I want at a later date. I will go ahead and drill and tap it in three positions in advance, and probably never need more. Will also come in handy for temporarily bolting other stuff to the floor.
