Access floor mounting assembly

Abstract

An assembly for mounting access flooring over a permanent surface is comprised of a plurality of supporting pedestals. Each pedestal carries an upper panel support plate and each plate has a plurality of precisely dimensioned indexing members rigidly fastened thereto, one of said members being precisely positioned adjacent each corner of the plate. Each of the floor panels is provided with a precisely dimensioned indexing member receiving aperture on the underside thereof adjacent each corner of the panel. Upon aligning and securing a small number of the pedestals over the permanent surface over which the access flooring is to be mounted, and mounting flooring panels on the aligned and affixed pedestals by firmly engaging the indexing members into the indexing member receiving apertures in the panels, the remainder of the pedestals and floor panels are self-aligned for easy mounting over the remainder of said permanent surface. Moreover the precision fit between the panels and the support plates resulting from the precision dimensioning of the indexing members and the member-receiving apertures causes the access flooring to act as a structural diaphragm, thereby strongly resisting horizontal and vertical movement of the panels due to horizontal loads.
