Abstract:

A structural member comprising a sheet of industrial material in which is formed a plurality of dome-like projections of which at least the major portion of the configuration thereof in plan view is circular and said projections being located in the plane of said sheet in a structurally strategic geometric pattern which repeatedly blocks straight lines of vision across said sheet through said pattern of projections in all directions to form a one-piece rigid structural member capable of resistance to flexure and the intermediate portion of the sheet between said projections comprising arcuate continuous structural stress-resisting sections extending between the opposite edges of said member. Variations in patterns of projections comprise different embodiments of said member and, when fabricated, said member lends itself to a variety of end uses. When in the form of a composite panel, a flat sheet of planar material is affixed to the upper ends of said projections.

Abstract:

Disclosed is an access floor system with deep pile carpet covered panels. The deep pile fibers from adjacent panels intermingle with each other to visually obscure the cracks between the panels. Disclosed is a tool and method for inserting or reinserting such panels into the floor system without pinching carpet pile between the panel edges. Disclosed is a floor system having service conduits running between adjacent panels but being visually undetectable due to the uniform appearance of the deep pile carpet covering.
