Abstract
Abstract The invention relates to a prefabricated building structure utilizing precast concrete steel reinforced T-shaped building elements and precast concrete steel reinforced hexagonal shaped columns. The T-shaped building elements are arranged in building units to form the framework of the building structure, said units respectively constituting the floors and roof of the structure and being vertically aligned and spaced apart by means of the columns. Each building element comprises a diamond shaped slab and an integral beam extending along the major axis of the slab on the under side thereof. The hexagonal shaped columns are each provided with a plurality of vertically spaced annular shelves upon which the ends of the T-shaped building elements on the major axes thereof rest. Moment connections are welded in the field between adjacent slabs and between the building elements and columns.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
194 words
A building structure comprising a plurality of building units which are vertically aligned and spaced apart by means of vertical columns, each building unit comprising at least three substantially identical T-shaped building elements, each element having a diamond shaped slab provided with a smooth upper surface and a lower surface and an integral beam engaging and arranged perpendicular to the lower surface of the slab, each slab having four sides of equal length arranged to form two oppositely facing angles of 60* on a major axis of the slab and two oppositely facing angles of 120* on the minor axis of the slab, the integral beam of each T-shaped building element extending along the major axis thereof, said T-shaped building elements being joined together, with each slab having one of its sides opposite and in close proximity to a side of one of the remaining slabs and each slab having a second side which intersects said one side opposite and in close proximity to a side of another of the remaining slabs, said vertical columns engaging the ends of the T-shaped building elements along the major axes thereof of each of said building units.
Claim 2
Dependent Claim
194 words
A building structure comprising a plurality of building units which are vertically aligned and spaced apart by means of vertical columns, each building unit comprising at least three substantially identical T-shaped building elements, each element having a diamond shaped slab provided with a smooth upper surface and a lower surface and an integral beam engaging and arranged perpendicular to the lower surface of the slab, each slab having four sides of equal length arranged to form two oppositely facing angles of 60* on a major axis of the slab and two oppositely facing angles of 120* on the minor axis of the slab, the integral beam of each T-shaped building element extending along the major axis thereof, said T-shaped building elements being joined together, with each slab having one of its sides opposite and in close proximity to a side of one of the remaining slabs and each slab having a second side which intersects said one side opposite and in close proximity to a side of another of the remaining slabs, said vertical columns engaging the ends of the T-shaped building elements along the major axes thereof of each of said building units.
