2. Description of the Related Art In recent years, large-scale multipurpose halls, halls, and the like have been constructed one after another with the enhancement of social capital. When holding a music-related event in an event hall with a large space of a main facility such as a multipurpose hall or hall, change the partition position, raise or lower the entire ceiling, and change the air volume to obtain good acoustic characteristics I have to. In addition, artificial lighting is mainly used for lighting of such event halls, and the technology for utilizing natural light has not been sufficiently established.

[0003]

In the above-mentioned conventional multipurpose event hall, the ceiling is raised and lowered uniformly, so that it is not possible to create an arbitrary best spatial style suitable for the event use. That is, the facility adjustment function for enhancing the effect of the performance on the performer's side and the audience's scale arrangement was insufficient. In addition, there is no sufficient facility for appropriately taking in natural light and utilizing it for event setting and the like, and furthermore, natural light cannot be taken or blocked in an arbitrary space style.

[0004] The present invention has been made in view of the above circumstances, and can be changed to an optimal ceiling pattern arbitrarily in accordance with the content of an event or a performance event with a simple configuration, and can select any daylighting and shading of natural light. The purpose is to provide a ceiling.

[0005]

In order to achieve the above object, the present invention comprises a lifting device for arranging a large number of units on a ceiling portion in a state where there is no gap in a plan view and individually raising and lowering the units. It is characterized by having. Further, the vertical cross-sectional shape of the unit is a polygon.

[0006] The present invention is also characterized in that rectangular units in a plan view are linearly arranged. In addition, a plurality of rectangular units are provided, and rectangular units of the same type are arranged in one direction, and the vertical cross-sectional shapes of units adjacent in multiple directions are polygons having different shapes.

[0007] Further, the unit is characterized in that the rings are rings having different diameters. Further, the vertical cross-sectional shapes of adjacent ring-shaped units are polygons having different shapes.

[0008]

By individually raising and lowering the units by the lifting device to change the height, it is possible to select a ceiling shape in a horizontal state or in an inclined state having an arbitrary slope, and furthermore, in a substantially flat state and an acoustic effect. You can select a stepped ceiling surface with an effective saw tooth condition. At this time, a light-shielding state is obtained by continuously overlapping the vertical cross-sectional shapes of the respective units, and natural light can be collected through the discontinuous portion by non-overlapping the vertical cross-sectional shapes of the respective units. .
