The subassemblies are made up of elongated structural members (114, 116, 118, 120) interconnected by clamping assemblies (106, 108, 110, 112). The clamping assemblies are made up of clamp elements (20a, 20b) with recesses (28, 30) which extend part way around the structural members and third portions (26) with cylindrical recesses (36) in which the ends of other elongated structural members are locked. | |
