<p>A polymer tile for forming a floor covering, comprising a perimeter wall (14) for providing support and for enclosing a perimeter boundary for the tile. A honeycomb configuration of intermediate wall structure is interconnected between inner portions of the perimeter wall and forms recurring hexagon units of hexagon support walls (20) of common dimension (Fig. 1), wherein the hexagon support walls (20) have a height common with a height of the perimeter wall for providing support for a load imposed at a top surface of the tile within an intermediate area. A plurality of ribs (22) of lesser height than the hexagon support walls (20) are disposed in traversing orientation between opposing vertices of the hexagon support walls (20), and are joined at a central axis of the hexagon units as a common load transfer point to form a tile grid defining a plurality of hexagon support walls reinforced by equilateral triangles of lesser height formed within the hexagon units of the tile.</p> |
