A truss frame with three-dimensional bracing includes at least three top rails which are joined together so as to define a substantially planar surface. A plurality of bracing members are attached to the top rails and depend toward a bottom connection which has a predetermined location with respect to the top rails. The bottom connection location is chosen so that the bracing members form truss-like braces for the top rails. In one embodiment, the top rails, bracing members, and bottom connection form the shape of a pyramid. A plurality of there truss frames is utilized to form a modular platform. The platform also includes means for fastening the top rails of adjoining truss frames together so as to form a continuous top chord in a direction parallel to that spanned by the connected truss frames. The platform preferably further includes means for connecting together the bottom connections of the truss frames so as to form a bottom chord which also extends in a direction parallel to that spanned by the connected frames. The modular platform may also include filler panels connected between predetermined ones of the truss frames, as well as decking mounted on the truss frames so as to provide a substantially continuous supporting surface and railing members which may be attached to the truss frames so as to provide the platform with a guardrail around at least a portion of the perimeter thereof. |
