Abstract

Abstract A modular building structure includes a base formed with an upper planar portion, a lower planar portion spaced from the upper portion to define an interior space therebetween and sidewalls extending between the upper and lower portions and having a convex, outwardly extending shape. A hollow upper shell with outer sidewalls is joined to the base. The base and upper shell are preferably constructed of an inner layer of concrete, an intermediate layer of an insulating material and an outer layer of a waterproof material. A plurality of modules are interconnected by hollow passageways which communicate with the interior of each module to define a continuous open space throughout the interconnected modules.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 132 words
A modular building structure comprising: an integral base completely nestable in ground surrounding the structure, the integral base having a lower planar portion in contact with the ground, sidewalls having an outwardly facing convex form extending outwardly from the lower planar portion and an upper planar portion extending between the sidewalls to define a hollow space between the lower planar portion and the upper portion; and a hollow upper shell having a continuous outer wall perpendicular to the upper planar portion and an outwardly facing convex upper surface contiguous thereto opposite the base, the hollow upper shell integrally joined to the sidewalls and upper planar portion of the base, wherein the hollow shell and the base are formed of an inner layer of poured concrete which is applied in its non-solid form.
Claim 2
Dependent Claim 132 words
A modular building structure comprising: an integral base completely nestable in ground surrounding the structure, the integral base having a lower planar portion in contact with the ground, sidewalls having an outwardly facing convex form extending outwardly from the lower planar portion and an upper planar portion extending between the sidewalls to define a hollow space between the lower planar portion and the upper portion; and a hollow upper shell having a continuous outer wall perpendicular to the upper planar portion and an outwardly facing convex upper surface contiguous thereto opposite the base, the hollow upper shell integrally joined to the sidewalls and upper planar portion of the base, wherein the hollow shell and the base are formed of an inner layer of poured concrete which is applied in its non-solid form.
Claim 3
Dependent Claim 21 words
The modular building structure of claim 1 further including metallic reinforcement means disposed within the concrete forming the shell and base.
Claim 4
Dependent Claim 34 words
The modular building structure of claim 1 further including: a plurality of modules; and hollow passageways disposed between and interconnecting the plurality of modules and defining a continuous, interior space throughout the building structure.
Claim 5
Dependent Claim 19 words
The modular building structure of claim 1 wherein said defined hollow space is used for storage and building utilities.
Claim 6
Dependent Claim 30 words
The modular building structure of claim 1 further including a layer of solid insulating material disposed over and contiguous the outer surface of the concrete forming the shell and base.
Claim 7
Dependent Claim 15 words
The modular building structure of claim 5 wherein the insulating material comprises a synthetic foam.
Claim 8
Dependent Claim 14 words
The modular building structure of claim 6 wherein said synthetic foam comprises polyurethane foam.
Claim 9
Dependent Claim 24 words
The modular building structure of claim 5 further including an outer layer formed of a waterproof material disposed over the layer of insulating material.
Claim 10
Dependent Claim 15 words
The modular building structure of claim 8 wherein the waterproof material comprises a synthetic material.
Claim 11
Dependent Claim 16 words
The modular building structure of claim 6 wherein said synthetic material comprises a polymeric acrylic latex.
