PURPOSE:To form ceiling equipment such as lighting equipment into a unit so as to be assembled in a plant or the like and simplify construction on the building site while reducing the number of constituent members. CONSTITUTION:Square spaces 7 are formed by plural ceiling bars 6 suspended and held through suspension-holding fittings 4 hung down from a ceiling slab 1. A box-shape equipment aggregate unit 10 is fitted to supporting bars 6a provided across the opposed ceiling bars 6, 6 in each square space 7, and ceiling panels 8 are provided across the equipment aggregate unit 10 and the ceiling bars 6. Ceiling equipment such as at least lighting equipment 20 is built in the equipment aggregate unit 10. The number of constituent members is thereby reduced, and the equipment aggregate unit can be assembled previously in a factory or the like and constructed easily on the building site. |
