Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
246 words
A building structure consisting of eight modular units for assembly on site, each modular unit comprising a rectangular base panel bordered on two intersecting outer edges by projecting wall panels meeting to form a corner of the building, the other two edges of the base panel comprising inner edges, means at the edges of the base panel and wall panels for assembling the components in building units comprised of four of the components, each four components forming a floor-and-wall assembly and a separate roof-and-wall assembly, the four components of one of the assemblies being assembled at the base panel, normal to an adjacent component with the shortest inner edge of one base panel parallel to the longest inner edge of an adjacent base panel and in which the projecting wall panels are substantially coplanar and form a rectangular closed wall for the respective assemblies, one assembly being juxtaposed on the other assembly at the edges of its projecting walls forming a complete enclosure, the joining vertical edges of the side panels of the assembly being horizontally spaced from the corresponding vertical joining edges of the side panel upon which it is juxtaposed so that vertical load bearing sides of the assemblies have no vertical joints in direct overlying relation, the base panels of the respective assemblies being connected to form a floor, or roof panel and including means for receiving means for closing an opening formed by portions of the inner edges of the base panels.

Claim 3
Dependent Claim
22 words
A building structure as defined in claim 1 wherein each component is pre-cast of mouldable material and is reinforced to support loads.
Claim 4
Dependent Claim
25 words
A building structure as defined in claim 2 wherein the components include means defining precast window and door openings in certain of the wall panels.
Claim 5
Dependent Claim
24 words
A building structure as claimed in claim 3 wherein releasable connecting means are provided between abutting edges of the wall panels and base panels.
Claim 6
Dependent Claim
61 words
A building structure as defined in claim 1, wherein a plurality of building structures are stacked one above the other with intermediate members mating with a center aperture formed by the mating of said rectangular base panels, said intermediate members defining the access housing between the building structures, and said components when assembled in an interlocking structure being self-supporting and load-supporting.
Claim 7
Dependent Claim
25 words
A building structure as claimed in claims 1 wherein the components are provided with a primary frame on which is moulded a light plastic material.
Claim 8
Dependent Claim
79 words
A building structure as claimed in claim 1 wherein releasable connecting means Are provided between the abutting edges of the wall panels, said releasable connecting means includes a channel having a plurality of spaced-apart projections on said channel, another channel member mounted on the edge of another abutting wall panel and having a plurality of slots receiving the projections on said other connecting member, said projections each including an aligned aperture through which a drop pin is removably disposed.
