Abstract:
A support structure comprising:a plurality of rigid structural members each comprising two side members connected by at least two cross members at positions adjacent to but spaced from ends of the side members such that the two side members are perpendicular to the cross members and parallel to one another, the two side members of a respective structural member being formed by two parallel metal tubes which are connected by the cross members, each cross member comprising a metal member welded to each tube generally at right angles thereto; anda plurality of joining members inter-connecting the structural members, each joining member comprising two open-ended tubes connected at generally a right angle such that the connected structural members form a rigid structure;wherein the open-ended tubes have an inner surface and the ends of the side members have an outer surface shaped such that the ends of the side members are inserted as a free sliding fit into the open-ended tubes,wherein at least one of the structural members is positioned in a generally horizontal manner such that the cross members are parallel with a ground surface and at least two of the structural members are generally vertical and coupled to a respective end of the horizontal structural member by the joining members at generally right angles and extend downward therefrom such that the cross members of the vertical structural members are parallel, and;wherein there is provided an end flange member including a tubular portion for receiving an end of one of the side members of a structural member and a flange portion at right angles to the tubular portion.
