  • Patent number: 5499476
    Abstract: A raised flooring system and methods of forming components of such a system are disclosed. Systems consistent with embodiments of the present invention utilize thin sheet metal, typically galvanized steel, base plates laid side by side on an existing floor. Attached in a rectilinear pattern to the base plates are stand-offs, which support floor panels forming the raised or false floor (which in turn are typically covered with carpet tile). In addition to supporting the floor panels, the stand-offs form a network of channels where conduit, cables, hoses, pipe and similar materials can be routed. The stand-offs are punched and then formed from thin sheet metal, also typically galvanized steel, and have an overall shape generally that of a truncated cone achieved with four arms that have rolled edges for enhanced load-bearing capacity.
