Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
114 words
A space structure for building purposes including a plurality of space modules stacked one above the other with each space module comprising: a plurality of beams joined together to form a truncated tetrahedral shape having side walls; a plurality of ribs extending between the beams forming the side walls; means connecting the rib ends to the adjacent beam to form rib-beam joints; means fastening the space modules together in stacked arrangement such that at least some of the side walls on one side of the structure do not lie in the same plane, and sheeting means covering the side walls and exposed surfaces of the modules thereby to form an enclosed multi-level space structure.
Claim 2
Dependent Claim
114 words

Claim 3
Dependent Claim
18 words
A space structure as defined in claim 1 wherein the ribs and adjacent beams each form equilateral triangles.
Claim 4
Dependent Claim
31 words
A space structure as defined in claim 2 wherein the modules are stacked such that the rib-beam joints of adjacent stacked modules are abutting thereby to form a rigid load-bearing structure.
