How are the pedestals affixed to the structural slab, and floor panels affixed to the pedestals?
Once the concrete floor slab has been sealed to reduce dust, the pedestals are laid out according to the predetermined grid and glued (sometimes bolted for seismic purposes) to the slab. After components for the UFAD and/or cable management systems have been installed and positioned, the floor panels can be laid. Four pedestals typically support each square panel at its corners. Ideally, pedestal-to-panel connections would comprise a mechanism enabling both a firm securing and easy removal of the panel. Currently available devices include screw fasteners or bolts at each corner of the panel, where a pedestal head is located; and for panels held by their self weight alone pedestals may have flanges designed for maximum support and gravity-lock collars to ensure levelness. In areas regulated by seismic building codes, pedestals can be braced and fitted with special seismic-bases.
