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.

Abstract: A modular, symmetrical space frame structure utilized in the construction of special architectural spanning structures comprises standardized component parts made of corrosion resistant aluminum or high-strength plastic composite for preferred exterior application and of steel for interior application - all manufactured to precise dimensional tolerances giving the assembled structure an inherent uniformity in the transfer of tension/compression load factors within the web and chord members. A basic standardized eight-way connector capable of connecting four diagonal web members and four horizontal chord members can be interchangeably installed in both the top and bottom chord assemblies thus minimizing the number of different component parts required to assemble the structure and also resulting in a totally symmetrical design.
