Fecha de publicación: -- Fuente: WIPO "rice" A modular multiple story structure which utilizes, as its principal component, a module formed of an elongated reinforced precast slab of concrete having an integral single leg or column at one end only, the leg having a haunch or shoulder at one side to support the end of another module in axial alignment; the modules being arranged for placement side-by-side as well as end-to-end and capable of being stacked with the legs in vertical alignment to form vertical columns of a multiple story structure. Removable legs are provided for each module, at its end opposite from the integral leg, to facilitate installation. The modules may be spaced laterally to receive and support leg free slab modules which may be cast in place or precast. The modules forming each floor are provided with a set of tendon guideways extending in one horizontal direction and may include a second set of guideways disposed in alignment. The horizontal and vertical guideways receive tendons which are capable of being tensioned then secured under tension to place the concrete modules under compression. Selected modules may be modified, such as disposing their slabs at an incline and changing their legs or columns to form ramps for connecting the floors formed by the other modules.
