Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
154 words
A building module for assembly into a multiple module building comprising a unitary hollow formed module having a continuous outer skin free from supporting structural framework and a spaced inner skin separated from said outer skin by spacer means including spaced apart roof and bottom members connected by arcuate vertical corner members, at least one side wall opening defined by the roof, the bottom and the corner members, interchangeable fastening means in said opening, adapted selectively to fasten adjacent modules together and to fasten an insert therein, and a vertical support column beneath each said module engaging the bottom generally centrally thereof and supporting said module and placing said module in stress, a portion of the outer skin adjacent and surrounding the support column being stressed in compression and the balance of said skin being stressed in tension, said support column being stressed in vertical and radial compression at its engagement with the module.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
37 words
A building module as claimed in claim 1 wherein the column is a cylindrical pedestal which enters an opening in the bottom of the module and is provided with a supporting flange on which the module rests.
Claim 4
Dependent Claim
28 words
A building module as claimed in claim 1 wherein the interchangeable fastening means includes a ring which engages within an annular groove in the periphery of the opening.
Claim 5
Dependent Claim
37 words
A building module as claimed in claim 1 wherein the module has a generally equilateral triangular horizontal section and is formed of foamed resin between spaced impermeable inner and outer skins, with the outer skin under tension.
Claim 6
Dependent Claim
18 words

Claim 9
Dependent Claim
53 words
A building module as claimed in claim 7 wherein the support column extends through an opening in the bottom portion of the module to the level of said ledge to support the floor member and a ring fixed to the outer periphery of the column engages the module bottom portion at said opening.
Claim 10
Dependent Claim
24 words
A building module as claimed in claim 1 wherein the support column is formed of foamed resin between spaced impermeable inner and outer skins.
Claim 11
Dependent Claim
119 words
A building module for assembly into a multiple module building comprising a hollow formed module including at least one generally equilateral triangular horizontal section with spaced apart roof and bottom members connected by arcuate vertical corner members, at least one side wall opening defined by the roof, the bottom and the corner members, and interchangeable fastening means, adapted selectively to fasten adjacent modules together and to fasten an insert therein, said fastening means being a generally ovoid split ring having a pair of parallel radially outwardly extending flanges, each engageable in an annular groove in the periphery of an opening and spring loaded cam means urging the ring into engagement with the opening with the flanges in said groove.
