D-ring/tie down installation on an insulated garage floor

I use a Condor chock that sits on a couple of pins on an aluminum plate. The plate has slots for the floor D-rings to fit through, and the tie downs hook to the D-rings. Nothing is permanently attached to the floor and all is easily removable in just a couple minutes. The rear of the bike is snugged down, but not super tight, and the front is only lightly tensioned. Works a treat.
