Abstract
Abstract A plural story building comprised of a number of basic precast concrete components, said components being held to a minimum and being so constructed to allow factory assembly of the components to such an extent that plumbing, electrical wiring, heating and ventilating, closets, bathroom fixtures, lighting fixtures, door frames, window frames, etc., are installed prior to shipment to the erection site thereby reducing field erection time. The basic components consist mainly of a corridor box forming the inside corridor''s load bearing walls and ceiling and also resisting horizontal forces, a column component forming the outside walls, a slab component forming the floor for one level and the ceiling of the level below, and wherein the slab component is supported by and attached to a shelf in both the corridor box and the combination column, beam, panel component.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
352 words
A multistory building including a plurality of living compartments, the improvement comprising corridor means, vertical column means and slab means, each of said vertical column means, slab means, and corridor means being of unitized reinforced precast concrete construction, said corridor means and said vertical column means being spaced parallel and opposite one another and said slab means extending between said corridor means and said vertical column means, said corridor means being of substantially inverted U-shape and including a top wall and two opposite and substantially parallel, vertical sidewalls depending downwardly therefrom, each of said sidewalls having a plurality of integral vertical ribs extending outwardly in a generally normal direction therefrom, each of said ribs forming a two-tiered step means at their upper junction with said depending sidewallS, said two-tiered step means comprising upper and lower seats in which said lower seat is inset from the outer face of said rib to an upstanding wall of said rib and said upper seat is inset from the top edge of said upstanding wall of said rib along the horizontal plane of the top of said rib to a second upstanding wall formed by the outer wall of said depending side of said corridor means, mechanical fastener means at least partially embedded in said top wall and extending into said recesses for connection to complementary fastener means extending outwardly from a corridor means, supported on said upper seats; said slab means resting on said lower one of said seats of said ribs, further mechanical fastening means connected to said slab means at each end thereof for permanently attaching said slab means to said vertical column means at one end thereof and to said corridor means at the other end thereof, whereby said slab means forms the ceiling of one of said plurality of living compartments and the floor of another of said plurality of living compartments of said multistory building, and said vertical column means forms one outside wall of said one of said plurality of living compartments and said corridor means forms the opposite wall of said one of said plurality of living compartments.
Claim 2
Dependent Claim
352 words
A multistory building including a plurality of living compartments, the improvement comprising corridor means, vertical column means and slab means, each of said vertical column means, slab means, and corridor means being of unitized reinforced precast concrete construction, said corridor means and said vertical column means being spaced parallel and opposite one another and said slab means extending between said corridor means and said vertical column means, said corridor means being of substantially inverted U-shape and including a top wall and two opposite and substantially parallel, vertical sidewalls depending downwardly therefrom, each of said sidewalls having a plurality of integral vertical ribs extending outwardly in a generally normal direction therefrom, each of said ribs forming a two-tiered step means at their upper junction with said depending sidewallS, said two-tiered step means comprising upper and lower seats in which said lower seat is inset from the outer face of said rib to an upstanding wall of said rib and said upper seat is inset from the top edge of said upstanding wall of said rib along the horizontal plane of the top of said rib to a second upstanding wall formed by the outer wall of said depending side of said corridor means, mechanical fastener means at least partially embedded in said top wall and extending into said recesses for connection to complementary fastener means extending outwardly from a corridor means, supported on said upper seats; said slab means resting on said lower one of said seats of said ribs, further mechanical fastening means connected to said slab means at each end thereof for permanently attaching said slab means to said vertical column means at one end thereof and to said corridor means at the other end thereof, whereby said slab means forms the ceiling of one of said plurality of living compartments and the floor of another of said plurality of living compartments of said multistory building, and said vertical column means forms one outside wall of said one of said plurality of living compartments and said corridor means forms the opposite wall of said one of said plurality of living compartments.
Claim 3
Dependent Claim
85 words
A multistory building as in Claim 1 wherein said vertical column means comprises a plurality of column sections, each said column section being of integrally cast one piece construction comprising two substantially vertical columns, each said column being substantially parallel to and spaced a distance from one another, connection means at each end of said vertical columns, a beam extending between said vertical columns and intersecting therewith at substantially the respective midpoints thereof, and said beam including means for supporting and securing said slab means.
Claim 4
Dependent Claim
50 words
A multistory building as recited in claim 1 in which said slab means has a main rectangular area and perpendicularly extending ribs integrally and longitudinally connected along each edge thereof, each of said ribs being in registration with a corresponding one of said vertical ribs integral with said depending sidewalls.
Claim 5
Dependent Claim
37 words
A multistory building as recited in claim 1 in which said slabs have a plurality of perpendicularly extending parallel spaced ribs longitudinally positioned for alignment with corresponding ribs of said vertically depending sidewalls of said corridor means.
