Monolithic structural member for foundation or ceiling system
Abstract
Abstract A STRUCTURAL MEMBER FOR FOUNDATION OR CEILING SYSTEMS COMPRISING A MONOLITHIC BODY OF SHEET MATERIAL, PREFERABLY COMPOSED OF A SYNTHETIC RESIN THAT MAY BE READILY SHAPED BY VACUUM FORMING OR OTHER SUITABLE TECHINQUES. ALIGNED ROWS OF HOLLOW, QUADRILATERAL, GENERALLY FRUSTOPYRAMIDAL ELEMENTS PROJECT UPWARDLY FROM THE BASE PLANE OF THE BODY AND PRESENT SPACED, LOAD-SUPPORTING SURFACES THAT DEFINE THE MOUNTING CENTERS FOR THE OVERLYING FLOOR OR ROOF. ACCORDINGLY, THE BASE OF THE BODY PRESENTS A GRID OF SURFACES ON ITS UNDERSIDE AT THE MOUTHS OF THE CAVITIES FORMED BY THE HOLLOW SUPPORT ELEMENTS. IN A FOUNDATION SYSTEM, THE BASE GRID DIRECTLY OVERLIES A PAD OF SAND, SLIT OR GRAVEL CHIPS TO SEAL EACH INDIVIDUAL CAVITY AND THEREBY TRAP AIR THEREIN TO ESTABLISH AIR POCKETS OF RESISTANCE TO LOAD. A SINGLE CHAMBER IS FORMED BENEATH THE OVERLYING FLOOR BETWEEN THE UPSTANDING SUPPORT ELEMENTS TO PROVIDE A NETWORK OF INTERCOMMUNICATING CHASES FOR PLUMBING AND ELECTRICAL RUNS, AND DEFINE A DUCT BENEATH SUBSTANTIALLY THE ENTIRE FLOOR FOR HEATING AND AIRCONDIDTIONING PURPOSES.
