Abstract
Extruded floorboards having integrated standoffs, or legs, to offset them from the ground or floor underneath, are disclosed in which adjacent floorboards share a common leg for standing off. On each side of the cross section of a floorboard, a shorter leg mates with a longer leg of an adjacent floorboard through a tongue & groove. The mated legs are supported by the longer leg and a foot at the bottom of the longer leg. A stiffening rib is included. The longer leg is longer than the shorter leg and stiffening rig by a predetermined distance so as to leave clearance for air bearings or other components underneath an assembled floor.
