<p>The unit is made up of panels (2) held between regularly spaced risers (5) and a bottom and a top horizontal metallic bracing band (3, 4). The roof has three runners (7) which extend from the central connecting unit (8) to the three corners of the top band. The connecting unit is above the top band and in the centre of the base triangle, while intermediate runners (9) support capping panels (27). The type of unit shown uses a truncated base triangle and has door and window units. By utilising a small number of different elements the unit can produce a large number of combinations and variations.</p> |
