SPACE FRAME STRUCTURE

摘要

A space frame structure has parallel spaced lower and upper sub-frames joined by interconnecting members, each sub-frame comprising a multiplicity of members connected in a grid, and a concrete layer secured to the upper sub-frame, wherein the concrete layer embeds the grid members of the upper sub-frame in the layer to form a composite upper sub-structure. Preferably the structure comprises permanent shuttering supported on the grid members of the upper sub-frame within the depth of the upper sub-frame, the concrete layer being laid on the shuttering to a depth sufficient to embed all of the grid members above the shuttering in the layer.
