Abstract
Abstract Concrete rooms, each having an integrally cast top segment, consisting of a top panel and three sidewalls, and a precast floor segment, secured to the top segment during its integral casting, are stacked on top of one another to form a rigid structure of multiple floors. The rear ends of the rooms have integrally cast cantilevered overhangs such that when the rear ends of two stacks of rooms are positioned adjacent one another the cantilevered overhangs form floors and ceilings for the corridors defined by the space between the stacks. Each stack of rooms consists of an alternating arrangement of long and short rooms, each short room having a locking ridge at its forward end for locking into an opening formed across the forward end of a corresponding longer room.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
116 words
A structural system comprising a plurality of precast concrete rooms stacked together to form a rigid structure each room having a top panel integrally formed with three sidewalls, at least one of the sidewalls having an opening, and a floor secured to the sidewalls, the floor being precast and secured to the walls simultaneously with integral casting of the walls, the stacked rooms defining pairs of interlocking concrete rooms of long and short lengths, the lower room being longer than the upper room and having an opening adjacent its forward end, the upper room having a projecting ridge along its lower front edge, the ridge being adaptable for interlocking with the opening of the lower room.
Claim 2
Dependent Claim
116 words
A structural system comprising a plurality of precast concrete rooms stacked together to form a rigid structure each room having a top panel integrally formed with three sidewalls, at least one of the sidewalls having an opening, and a floor secured to the sidewalls, the floor being precast and secured to the walls simultaneously with integral casting of the walls, the stacked rooms defining pairs of interlocking concrete rooms of long and short lengths, the lower room being longer than the upper room and having an opening adjacent its forward end, the upper room having a projecting ridge along its lower front edge, the ridge being adaptable for interlocking with the opening of the lower room.
Claim 3
Dependent Claim
20 words
The structural system of claim 1 wherein the building has both rows and columns of alternating long and short rooms.
Claim 4
Dependent Claim
82 words
The structural system of claim 1 wherein each room has a vertically disposed steel plate and horizontally projecting reinforcement rods secured to the forward edge of each sidewall, such that an interlocking pair of units can be positioned to align the steel plates so that they can be welded together to securely couple each pair of units, the reinforcement rods being alignable with the reinforcement rods of adjacent modules so that they can be welded together to secure adjacent stacks of units.
Claim 5
Dependent Claim
152 words
A building comprising a plurality of precast concrete rooms stacked together, each room including a floor, at least three load-bearing sidewalls integral with the floor, and a top panel integral with the sidewalls, each pair of stacked rooms having a cooperating floor and top panel defining an interlocking interface with a projecting ridge integral with one room constructed to interlock with an opening in the other room so the two rooms form a rigid structure; and a vertically disposed steel plate abutting a sidewall of each room, and horizontally projecting reinforcement rods embedded in each sidewall, the steel plates being aligned when the rooms are stacked together so that the plates can be welded together to securely couple the rooms, with the reinforcement rods of each room being arranged to align with the reinforcement rods of an adjacent room so the rods can be welded together to secure adjacent stacks of rooms.
Claim 6
Dependent Claim
152 words
A building comprising a plurality of precast concrete rooms stacked together, each room including a floor, at least three load-bearing sidewalls integral with the floor, and a top panel integral with the sidewalls, each pair of stacked rooms having a cooperating floor and top panel defining an interlocking interface with a projecting ridge integral with one room constructed to interlock with an opening in the other room so the two rooms form a rigid structure; and a vertically disposed steel plate abutting a sidewall of each room, and horizontally projecting reinforcement rods embedded in each sidewall, the steel plates being aligned when the rooms are stacked together so that the plates can be welded together to securely couple the rooms, with the reinforcement rods of each room being arranged to align with the reinforcement rods of an adjacent room so the rods can be welded together to secure adjacent stacks of rooms.
Claim 7
Dependent Claim
44 words
A building according to claim 4 wherein each room has a cantilevered overhang integral with an edge of its respective top panel, each overhang including means for joining it with another room disposed adjacent to it to form a corridor between the adjacent rooms.
Claim 8
Dependent Claim
76 words
A building according to claim 4 wherein each interlocking pair of stacked rooms defines a lower room and an upper room; and wherein the ridge is integral with the bottom surface of the floor of the upper room so as to project downwardly toward the lower room, and the opening is formed in the top panel of the lower room so that the ridge interlocks with the opening when the upper and lower rooms are stacked.
