PROBLEM TO BE SOLVED: To hoist a heavy weight by providing a bent column extending downward on a shape steel mounted on a lower flange of a steel beam in an attachable/detachable manner, and mounting a ceiling member supporting structural member on the bent column so that the ceiling member supporting structural member is supported by the steel beam through the steel shape and the bent column. SOLUTION: An end part of a shape steel 2 is connected to each lower flange D of two steel beams B opposite to each other from its lower side, and two bent columns 3 are extended to a lower part of the steel shape 2. The steel shape 2 and a bent column 3 are support parts 1, an intertruss brace 10 to be stretched to the bent column 3 or a suspension bar 11 is connected to a lower end part of the bent column 3 to mount a ceiling member supporting structural member 12 thereon. The support parts 1 are arranged at a place where the hoisted load in a ceiling is large so that relatively heavy ceiling panel and ceiling member supporting structural member 12 are supported by the steel beams B through the support parts 1. Because even a large hoisted load in the ceiling can be supported without mounting a brace, the interference of the brace with equipment in the ceiling becomes less, the layout of equipment can be freely achieved. |
