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.
A structural truss comprising an elongate framework having opposite ends, connectors fixed at said opposite ends each of a forked form having two spaced parallel limbs fixedly positioned relative to said framework and extending longitudinally thereof away from said opposite ends, which said limbs are disposed to be vertically spaced apart in a normal orientation of the truss for use and have registering holes, and retaining means which insert into said holes, wherein each said connector has an anchorage by which it is retained to a respective one of said opposite ends of said framework and has a central plane, and spaced limbs which provide said forked form of said connector and are asymmetrically positioned relative to said central plane.
A structural truss comprising an elongate framework having opposite ends, connectors at opposite ends each of a forked form having two spaced limbs which are disposed to be vertically spaced apart in a normal orientation of the truss for use and in which are registering holes, and retaining means which insert into said holes, wherein:
A structural truss comprising an elongate framework having opposite ends, connectors fixed at said opposite ends each of a forked form having two spaced parallel limbs fixedly positioned relative to said framework and extending longitudinally thereof away from said opposite ends, which said limbs are disposed to be vertically spaced apart in a normal orientation of the truss for use and have registering holes, and retaining means which insert into said holes, wherein said framework has tubular longitudinal frame members having opposite ends and said connectors are fixed to said opposite ends of said longitudinal frame members, and said connectors have sleeves which fit over and are secured to said opposite ends of said longitudinal frame members.
