Modular transportable floor decking system

A modular portable floor decking system for constructing a temporary or permanent flooring structure, said system comprising a plurality of extruded metal hollow support posts and a plurality of beams interconnectable with said posts to form a support frame, decking members securable across said beams;

• said support posts each having flat outer surfaces, two or more longitudinal connecting channels each disposed internally of an associated one of said flat outer surfaces of each of said posts, said two or more longitudinal connecting channels each having a central narrow slot extending along their respective flat outer surfaces;
• said beams each having opposed flat connecting end walls, a metal clamping shoe dimensioned for close sliding fit in said connecting channels is adjustably connected to said connecting end walls by two or more spaced fasteners extending through bores formed in said flat connecting end walls to retain said clamping shoe spaced adjacent an outer flat surface of said connecting end wall, said fasteners each having a threaded end engaged in threaded bores of said clamping shoe, and a tool engaging head accessible adjacent an inner surface of said connecting end wall;
• said beams being connected to said hollow support posts by spacing said shoe from said outer surface of said flat connecting end wall and sliding said shoe in one of said channels with said fasteners extending through said central narrow slot and tightening said fasteners when said beam is at a desired position with respect to said support post whereby to clamp said outer flat surface of said connecting end wall of said beam on said flat outer surface of said support post.
