Abstract:
A unitized, pre-fabricated access floor arrangement comprising:a. a quadrilateral modular stringer frame comprising four exterior sides and four diagonal interior sides of equal length, four corner pedestal joining means each connecting two exterior sides and two diagonal interior sides and comprising an indented top surface and a threaded perforation placed at the center of place where the exterior sides connect, and one diagonal pedestal joining means, said diagonal pedestal joining means placed at the center of the modular stringer frame and connecting the four diagonal interior sides and comprising an indented top surface and a threaded perforation placed at the center of place where the four diagonal sides connect; b. a plurality of leveling pedestals for vertical leveling of the modular stringer frame, each leveling pedestal comprising an upper housing, a traveling threaded male column and a foot, the upper housing further comprising an attaching means end, a threaded interior and a bottom end, the threaded male column further comprising a top end, a bottom end and a threaded surface, the foot further comprising an attaching means; c. a corner locking device comprising a flat plate and four attaching means, said flat plate further comprising four perforations, said flat plate shaped to sit on a top surface created by the four corner pedestal joining means of four modular stringer frames placed immediately adjacent to each other with the perforations of said plate geometrically distributed to match the perforations of the four corner pedestal joining means; d. a floor panel comprising a top surface and an underside, the underside comprising a diagonal indentation shaped so that the floor panel can be placed over a modular stringer frame and used to physically hold together two neighboring modular stringer frames by allowing the diagonal indentation to straddle two adjacent exterior sides of two neighboring modular stringer frames; e. a plurality of heating, ventilating and air conditioning diffusers which can be structurally integrated with individual floor panels as needed; f. a plurality of cable trays that can be hung from selected stringer frames to form cable chase ways in the space between a subfloor and the underside of the panel to guide power, voice and data cables; and g. a plurality of plenum dividers that can be inserted in a space created between the stringer frame and the subfloor in order to establish heating, ventilating and air conditioning zones.
