A DUCTWORK ASSEMBLY, SUPPORT AND SUSPENSION SYSTEM

摘要

A ductwork assembly comprising a pair of ducts (10, 11) and a supporting ladder structure (12) between them, the ladder structure (12) being suspended from above by cables. Each duct (10, 11) is supported from the adjacent side of the ladder structure (12) by half moon brackets by which it is cradled. Each half moon bracket is mounted at the end of an outwards extension of a rung of the ladder structure (12). The latter supports various services such as cables, cable trays, cable trunking, lighting systems, smoke detectors and/or security systems.
