Claims
- 1. An elevated false floor assembly of panels having a level and even tread surface, comprising a plurality of panels arranged side-by-side in rows and supported on pedestals at their corners, the sides of adjacent panels substantially abutting one another and being interconnected by releaseable tie means located intermediate the corners thereof, said panels each being load bearing and comprising upper and lower spaced apart metal sheets, at least one tie securing the spaced apart upper and lower sheets of each panel to the corresponding upper and lower sheets respectively, of an adjacent panel adjacent each abutting side thereof, the horizontal and vertical movements of any one panel being resisted and shared by said upper and lower sheets of adjacent panels, said tie extending generally vertically for substantially the entire panel thickness between said spaced apart upper and lower sheets of that panel, said tie being removable from above the tread surface.
- 2. The floor assembly of claim 1, wherein said tie is accessible and turnable at the upper metal sheet surfaces of adjacent panels.
- 3. The floor assembly of claim 1, wherein said tie is a threaded bolt and nut that directly bears on the upper sheet of one panel and the lower sheet of an adjacent panel.
- 4. The assembly of claim 3, wherein there are two sets of dissimilar panels arranged in checkerboard relationship, the panels of a first set having upper sheet edges that overlie and capture adjacent upper sheet rims of a second set.
- 5. The assembly of chain 4, wherein lower sheet flanges of said second set underlie lower sheet peripheries of said first set.
- 6. The assembly of claim 5, wherein a bolt passes through the panels of said first set adjacent each side thereof.
- 7. The assembly of claim 6, wherein said bolt engages a captured nut secured to each of said peripheries.
- 8. The assembly of claim 4, wherein the corners of the panels are truncated and rest on said pedestals.
- 9. The floor assembly of claim 1, wherein said tie is a turnable plug and each side of each panel has a perimeter with a recess, the recesses of adjacent panel sides having sockets in register to receive said plug.
- 10. The floor assembly of claim 9, wherein said plug has a lower lug that bears on the lower surfaces of adjacent panel sockets and an upper circular top portion that bears on the upper surfaces of said sockets.
