PCT No. PCT/AU89/00155 Sec. 371 Date Oct. 10, 1990 Sec. 102(e) Date Oct. 10, 1990 PCT Filed Apr. 7, 1989 PCT Pub. No. WO89/09863 PCT Pub. Date Oct. 19, 1989.The support (10) is securely clampable to a raised profile (12) of the roof decking (14) without piercing the decking and supports a safety barrier (34). Alternatively the support (10) may support a display sign or formwork locator. The support (10) comprises a clamp (24) and a support element (25) over which an upright support post (26) carrying the barrier (34) is telescopically received. The clamp (24) comprises a pair of clamping jaws (36 and 38) which are pivoted to each other and have respective feet (56) at their ends remote from the pivotal connection (44). The feet engage the deck (14) and particularly have respective projecting flanges (66) which cooperate with opposed undercuts on the raised profile (12) when the clamp (24) is tightened by a screw threaded arrangement (50, 52) remote from the pivotal connection (44). A brace (68) is provided with a clamp (84) similar to the clamp (24 ). The brace is rotatable about the support element (25) and the clamp (84) can be correspondingly adjusted to be clampable to the same or different profile (12) as the clamp (24). |
