A ceiling system bar (1) is fixed to a hanging bolt (17), which is set firmly on a steel frame base, in such a manner that an opened portion of the ceiling system bar (1) is directed downward. The hook frames (22) of ceiling panels (21) are engaged via air-tight members with F-shaped frame projections (6) which are provided on both lower side portions of the ceiling system bar (1). Panel holders (30) are provided so as to extend over the opposed portions of the ceiling panels (21) and ceiling system bar (1) to thereby join the ceiling panels (21) to the ceiling system bar (1). A floor system bar (40) is provided on a floor, which is opposed to the ceiling system bar (1), in such a manner that an opened portion of the floor system bar (40) is directed upward. In order to provide partitions (47) between the ceiling system bar (1) and floor system bar (40), the upper end portion of the partitions (47) is inserted into the opened portion of the ceiling system bar (1) via a ceiling frame (35), and the lower end portion thereof into the opened portion of the floor system bar (40). When these partitions (47) are not provided, a ceiling cover is set on the opened portion of the ceiling system bar (1), and a floor cover on the opened portion of the floor system bar (40). An illuminator can be provided in the opened portion of the ceiling system bar (1) via the ceiling frame (35). |
