Abstract

Abstract A MODULAR FRAME SYSTEM CAPABLE OF BEING CONSTRUCTED IN BOTH A VERTICAL AND HORIZONTAL DIRECTION TO A PREDETERMINED SIZE AND CONFIGURATION. A PLURALITY OF SPACED LAND STRUCTURES IN VERTICALLY TIERED RELATIONSHIP ARE PROVIDED AND EACH LAND STRUCTURE HAS MEANS THEREON TO PERMIT THE LAND STRUCTURE TO FUNCTION THE SAME AS THE GROUND SURFACE STRUCTURE OF A BUILDING. A PLURALITY OF SUBSTANTIALLY VERTICAL COLUMNS EXTEND UPWARDLY FROM THE GROUND AND THE COLUMNS HAVE BEAMS THEREON TO SUPPORT THE VERTICALLY SPACED LAND STRUCTURES. THE LAND STRUCTURE AND COLUMN SUPPORT ASSEMBLIES ARE ADAPTED TO RECEIVE AT LEAST ONE INSERTABLE CORE UNIT BETWEEN EACH PAIR OF SPACED LAND STRUCTURES IN A MANNER THAT WILL PERMIT EACH VERTICALLY INSERTED CORE UNIT TO BE CONNECTED TO A LAND STRUCTURE IN THE SAME MANNER AS IT WOULD NORMALLY BE CONNECTED TO THE GROUND SURFACE.
