Abstract
The present invention relates to a high-strength panel used as flooring in a clean facility, such as a semiconductor clean room. The high-strength panel comprises rim ribs, each having a tapered surface, formed at a respective rim portions of the panel. A main reinforcing rib divides an interior space defined by the rim potions into a plurality of square lattice sections. A plurality of auxiliary reinforcing ribs is arranged in each of the square lattice sections to divide the lattice sections into sub-sections, wherein a plurality of circular recesses is diagonally arranged in each sub-section, Each circular recess is surrounded by a circular rib. Accordingly, a supporting force for resisting a vertical load and an eccentric load is enhanced. Thus, the strength of the panel for resisting a concentrated load is increased by distributing the load downwardly concentrated at a specific location of the panel throughout the entire panel.
