ABSTRACT:
A structural truss, eg to provide support in building, exhibition, display lighting, decorative and other structures, comprises an elongate framework at opposite ends of which are connectors of a common forked form spaced limbs of which have registering holes for a retaining pin or bolt and are disposed to be vertically spaced apart in a normal orientation of the truss in use. The arrangement of the connectors relieves the retaining pins or bolts of at least a substantial portion of the load of, and on, the truss when it is in use. In the illustrated embodiment the connectors enable the truss to be inverted from one orientation to another for use, and two of the trusses to be connected together end to end. Securing in different orientations is facilitated by having the limbs of each connector offset relative to an anchorage of the connector to the framework, and having the limbs of a connector at one end of the framework offset in the opposite direction to the limbs of a corresponding connector at the other end of the framework.
