Elongate hollow structural members
First Claim
1. A hollow-section elongate structural member comprising a plurality of spaced apart elongate elements extending parallel to one another and a plurality of panels extending between and secured to the elongate members in spaced relation to form the hollow section with each elongate element having a pair of panel edges secured thereto, the panel edges have edge formations to be received by the respective elongate elements and each elongate element having an elongate open channel with a base and side walls, each edge formation of a panel being shaped to conform to a side wall and adjacent part of the base of a channel and clamping means for each channel for clamping the edge formations of a pair of panels in the channel;
- characterised in that the clamping means comprise a clamping member formed with a clamping facing having a main part flanked by side faces to act in cooperation with the base and side walls of the channel to clamp the edge formation of a pair of panels therein and securing means for securing the clamping members to the respective channels; and
in that spacer means are provided between the base of the channel and clamping member to maintain a minimum distance between the clamping member and the base of the channel.

Abstract
The disclosure relates to a hollow section elongated structural member comprising three parallel spaced channel section elements (13) with three panels (11) extending between the respective pairs of elements to form a hollow section member. The edges of the panels have edge formations (17) which are received in the channels, each edge formation being shaped to conform to a side wall (15) and adjacent base part (14) of a channel. Clamping members (18) are provided for each channel having a clamping face including a main part (19) flanked by said faces (21) to act in co-operation with the base and side wall of the channel (13) to clamp the respective edge formations of a pair of panels therein and screws (23) are provided for securing the clamping members to the channel to lock the edge parts of the channels in the channels and thereby create a rigid structue between the channels and panels. The arrangement is particulary suitable for lightweight structural members for frameworks to be used in supporting equipment such as lighting or other electrical apparatus, display devices, screens or the like, or for supporing canopies, roofing or walling.
