ABSTRACT:
An elongate truss 10 comprises a framework 14 of spars 16, 18, 20, 22, 24, 26. The truss 10 is open on one aspect and has the transverse cross section of a regular trapezium. This enables identical trusses to be stacked up for storage or transporting an internested manner one on top of the other. In addition, lights 62 may be mounted inside the truss 10 and drapes 72 are hung from one side of the truss 10. A removable cross brace 42 may be provided for connection at the open aspect of the truss between lower longitudinal spars 18 to prevent splaying of the truss when under load. The brace 42 may be stored by attachment to intermediate cross chords 22. A stack 10' of trusses may be stored on a trolley 28 and easily manhandled. A substantial number of the trusses, when stacked, may be stored in a set volume.
