there are a variety of concrete anchors/fasteners for this purpose. Everything from powder-driven nails, like ramset, to expanding metal sleeves, like RedHead (is that the name? Somehow it's not sounding right), or Tapcon threaded concrete screws that just screw into a hole in the concrete. You can browse all these at your local lumberyard or building center.
