DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling structure for a large-scale multipurpose event hall or the like.

[0002]

2. Description of the Related Art A dome-shaped stadium is used as a multipurpose event hall for various sports and concerts. In this stadium, it is known that a plurality of impermeable membranes are suspended from the ceiling to form a variable ceiling (movable ceiling), and the number, arrangement, and hanging position of the impermeable membranes are changed. Thus, the effects of various events to be held are enhanced.

[0003]

The conventional movable ceiling only enhances the effect of the stage around the stage or the like at the time of various events, and cannot cope with a large-scale event using the entire stadium. At the present time, it has not been possible to select and utilize natural light or shade in terms of lighting. Therefore, there is a need for a movable ceiling that provides an arbitrary and best spatial style and lighting conditions that are suitable for multipurpose event applications.

[0004] The present invention has been made in view of the above situation, and is intended for large-scale events using the entire hall, tennis,
It is an object of the present invention to provide a movable ceiling in a multipurpose event hall that can maintain the best spatial style (spirit) for small and medium-sized events such as concerts and sumo wrestlers, and can select natural daylighting and shading.

[0005]

In order to achieve the above object, according to the present invention, a large number of fan-shaped panels are arranged in a radial direction and a circumferential direction in a plan view to form a circular ceiling as a whole.
A lifting device is provided to raise and lower the individual panels
Alternatively, adjacent fan-shaped panels are connected by a link .

[0006]

[0007]

A circular ceiling is constituted entirely by a large number of fan-shaped panels, and each of the fan-shaped panels is individually raised and lowered by an elevating device, thereby obtaining a ceiling in an arbitrary inclined state and a ceiling surface of an arbitrary shape. By changing the height of the panels, natural light is taken from gaps in the vertical direction, and the height of adjacent fan-shaped panels is made substantially equal, thereby blocking natural light.

[0008]

FIG. 1 shows the overall situation of a dome stadium having a movable ceiling according to one embodiment of the present invention.

On a fixed roof 1 constituting a dome-shaped stadium, a circular elevating platform 3 is suspended and supported via a plurality of wires 2, and the elevating platform 3 is shown as being installed on the fixed roof 1. It can be moved up and down by an electric winch. A large number of fan-shaped panels 4 are arranged on the outer periphery of the elevating gantry 3 in a radial direction and a circular direction in a plan view, and constitute a circular ceiling 5 as a whole. In the figure, reference numeral 6 denotes a building structure, 7 denotes a seat, and 8 denotes a stage.

FIG. 2 is a partial plan view of the circular ceiling 5, and FIG.
5 is a view from arrow A in FIG. 2, FIG. 4 is a detailed situation in FIG. 3, and FIG.
2 shows a view in the direction of arrow B in FIG. 2 when natural light is taken, and FIG. 6 shows a view in the direction of arrow B in FIG. 2 when natural light is blocked.

[0011] The fan-shaped panels 4 are arranged in an overlapping state in the circumferential direction, and five fan-shaped panels 4 are arranged in the radial direction. As shown in FIG. 3, the fan-shaped panels 4 adjacent in the radial direction are connected by a curtain 10. The fan-shaped panel 4 is fixed to the roof 1 by two wires 11 (FIG. 1).
), Each wire 11 is connected to a lifting device (not shown), and the fan-shaped panel 4 can be individually raised and lowered. That is, as shown in FIG.
Can be raised and lowered in parallel with the adjacent fan-shaped panel 4 by two wires 11, and can be raised and lowered in a rotating state with respect to the adjacent panel 4 as shown in FIG. And a stepped ceiling surface can be selected.

As shown in FIG. 3 (a), by making the radially inner fan-shaped panel 4 lower and the radially outer fan-shaped panel 4 higher, the ceiling 5 has a lower central portion and a higher outer peripheral portion. I do. As shown in FIG. 3B, by making the heights of all fan-shaped panels 4 in the radial direction substantially the same, the ceiling portion 5 has a ceiling shape that is horizontally horizontal in the radial direction. Further, as shown in FIG. 3 (c), by making the radially inner fan-shaped panel 4 higher and the radially outer fan-shaped panel 4 lower, the ceiling 5 has a ceiling shape with a higher center and a lower outer circumference.

As shown in FIG. 5 (a), a part of the ceiling part 5 is formed into a ceiling shape inclined upward and downward by lowering the fan-shaped panel 4 on the left side in the circumferential direction and raising the fan-shaped panel 4 on the right side in the circumferential direction. . As shown in FIG. 5B, by making the heights of all fan-shaped panels 4 in the circumferential direction substantially equal, the ceiling portion 5 is formed into a ceiling shape that is horizontal in the circumferential direction. Further, as shown in FIG. 5 (c), by making the fan-shaped panel 4 on the left side in the circumferential direction higher and lowering the fan-shaped panel 4 on the right side in the circumferential direction, a part of the ceiling part 5 is formed into a ceiling shape inclined downward to the right. At this time, by changing the height between adjacent fan-shaped panels 4, natural light (indicated by an arrow in the figure) enters the stadium through the discontinuous portion, and natural light can be collected.

As shown in FIGS. 6 (a), 6 (b) and 6 (c), natural light is blocked in the stadium by adjoining and overlapping adjacent fan-shaped panels 4 in the ceiling shape shown in FIG. You.

As described above, the circular ceiling part 5 is constituted by a large number of fan-shaped panels 4 as a whole, and by individually raising and lowering the fan-shaped panels 4, the ceiling shape in a horizontal state or an inclined state having an arbitrary slope can be obtained. In addition to being able to select, a flat or stepped ceiling surface can be selected. At the same time, it is possible to actively utilize natural light as well as artificial lighting. Therefore, not only large-scale events using the entire stadium but also small-scale events such as concerts and tennis can be selected with good sound effects and construction effects.

In the above embodiment, the fan-shaped panels 4 adjacent to each other in the radial direction are connected to each other by the curtain 10, but the fan-shaped panels 4 are connected to each other using the link 21.
As shown in (a), (b), and (c) (corresponding to FIG. 3), a ceiling shape in an arbitrary inclined state can be selected.
(Corresponding to FIG. 4), a ceiling surface in an arbitrary state can be selected.

[0017]

According to the movable ceiling of the present invention, a large number of fan-shaped panels are arranged in the radial and circumferential directions to form a circular ceiling as a whole, and each fan-shaped panel is individually raised and lowered. The ceiling structure and ceiling surface in an arbitrary state can be selected with a simple structure, and at the same time, natural light can be actively utilized in an arbitrary space. As a result, it is easy to select the best sound, construction, and air-conditioning effects for a wide range of events, from large events that use the entire stadium to small and medium-sized events that use a portion of the stadium. It is possible to expand the range of use of the facility with a simple structure.
