Best way to hang loads from concrete….
I was chatting with my brother in law, and he wants very strong shelves (without any massive brackets…) in his kitchen… Of course its in a prewar NYC apartment that has 2.5 inch thick concrete and hollow walls behind. My first suggestion was a cabinet carcass hung onto lead anchors, and that was shot down becuase it would not match prexisting cabinets.
My next thought was a winner, somehow hanging threaded rod from the ceiling and making shelves out of 1 inch plywood, reinforcing with L angle in the backs of the shelves, and then securing the shelves to the rods… Kinda like the floating walkway from the famous Kansas City collapse, but without the collapsing part.
This leads me to wonder how to get a beefy anchor into a ceiling, and how to hang the rod from it, or should I just give up this whole line of thought. Can I just use a hilti type anchor?

I have hung hundreds of pieces of all thread (threaded rod) from wedge anchors in concrete. Drill the appropriate size hole, drive in the anchor and tighten with a wrench or socket and the wedge on the end of the bolt expands. There are plenty of variations on this but they all work pretty well. At that point you are left with male threads sticking out of the ceiling. Thread a nut on to the threads then a rod coupling and lock down the rod coupling. Now you have female threads ready to accept your all thread. Don't forget to put a nut on the all thread before you screw it into the rod coupling to lock it all down. Here is a link to what I am talking about.

That looks like exactly what I was thinking... off to the hilti man I go!
