Abstract: A monolithic, reinforced concrete framework for a multi-level, multi-unit building results from the utilization of factory prefabricated and finished wall panels, floor/ceiling panels and utility core modules, the juxtaposition of which, without forms, defines volumetric beam voids. The beam voids are exterior to the wall panels, floor/ceiling panels and core modules. Wall panels include light gage studs, which are loadbearing studs, and light gage column frames. Beam voids and column frames for a building level are poured with concrete at one time. Each building level is erected and poured in one day; and the next level can commence the following morning, without need for exterior scaffolds. The beams and columns carry the weight of the building down into the foundation. Large open areas, such as lobbies, can be provided, using building weight supporting trussed wall panels having support for the beams overlying the open area.

Abstract: A wall, such as a load bearing wall, and method for forming same. The wall comprises a core member having a substantial void therein and reticulated sheets of reinforcing material positioned on both sides of the core and spaced therefrom. The wall is formed as by spraying cementitious material through and around the sheet material thus to produce a composite wall comprising first and second panels of reinforced cementitious material in spaced relation, having a hollow core therebetween, said panels being joined together as a unitary structural member.
