Abstract: A support pedestal assembly for a raised floor system can be used with metal panels or wood core panels, can be used with or without grid members, and can be used with brace members for resistance to vibration and seismic shock. The support pedestal assembly includes a pedestal base, a vertical, adjustable height support column coupled to the base, and a pedestal head coupled to the top of the support column. The pedestal head includes a center region for coupling to the support column and four arms, each having an aperture therethrough, extending outwardly from the center region. In one configuration, the arms form a 45 degree angle with the edges of the floor panel and a downwardly extending projection near the corner of the floor panel mates with the aperture in the arm to locate the panel on the pedestal assembly and to prevent horizontal movement. A floor panel corner locator can be mounted in the center region of the pedestal head for use in conjunction with the wood core floor panels.
