Elevated floor structure
Abstract
Abstract THIS ELEVATED FLOOR STRUCTURE COMPRISES A RIGID FRAME CARRYING THE FLOOR PROPER AND SUPPORTED ABOVE THE SUBFLOOR BY A PLURALITY OF SPRINGS THAT ARE VERTICALLY COMPRESSIBLE TO ACCOMMODATE LOCAL DEFORMATIONS OF THE SUBFLOOR. EACH SPRING UNIT IS MECHANICALLY PREVENTED FROM EXPANDING BEYOND A PREDETERMINED LENGTH, REPRESENTING PRESTRESSING OF THE SPRING TO A FORCE THAT IS RELATED TO THE ANTICIPATED TOTAL LOAD. THE FLOOR PROPER COMPRISES INDIVIDUAL CAST METAL PANELS COATED WITH SEAMLESS, ELECTRICALLY INSULATING, RESILIENT MATERIAL. SPECIAL TIE-ROD BRACKETS, RESILIENT TIE-DOWN LINKS AND ADJUSTABLE SHIMS, ARE DESCRIBED. A MODIFIED STRUCTURE, SUITABLE FOR MISSILE LAUNCHING INSTALLATIONS AND THE LIKE, ACCOMMODATES LARGE AMPLITUDE VIBRATIONS BY PERMITTING THE ENTIRE FLOOR FRAME TO MOVE BOTH HORIZONTALLY AND VERTICALLY WITH RESPECT TO THE SUBFLOOR, WITH DISPLACEABLE PERIMETER PANEL STRUCTURES BETWEEN THE FLOATING FLOOR AND THE BUILDING SIDEWALLS. THE FLOOR FRAME IS YIELDABLY URGED TOWARD NORMAL POSITION IN RESPONSE TO BOTH GRAVITY AND RESILIENT FORCES.
