<p>A frame (12, 14) for supporting vertical loads and an aluminium tubular leg (16) for such frame (12, 14) is disclosed. The legs (16) are joined by a brace (68, 70, 120) arrangement and connectors are used for mechanical connecting the brace (68, 70, 120) arrangement to the legs (16) for stabilizing the legs (16) when under load. Each of the legs (16) has spaced portions which are substantially symmetrical about a plane containing the longitudinal axes of the frame legs (16) and which provide areas for mechanical connection of the brace (68, 70, 120) arrangement to the leg (16). Such mechanical connection of the frame (12, 14) provides a versatile frame (12, 14) which may be used in concrete forming work and which may be readily repaired.</p> |
