Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multipurpose and large-scale facility for holding various events, and more particularly to a complex arena in which an arena and a hall are arranged adjacent to each other.

[0002]

2. Description of the Related Art As is well known, a building called an arena has a form in which a staircase-like seat (stand) is provided around a circular or oval flat earth (arena court). Is a multi-purpose facility for holding various events such as sports events such as soccer and American football, music events such as rock concerts, exhibitions and trade fairs, etc. Has been built and is in operation.

By the way, such an arena is not only a large-scale one, but is widely modified to optimize the capacity of occupants, the arrangement of seats, the size and form of the arena court, etc., depending on the event to be held. However, it is required that such a change can be performed as easily and in a short time as possible. For this reason, conventionally, some measures have been taken to make a part of the stand movable or storable and to change the area or form of the arena court.

[0004]

However, in the arenas that have been in operation up to the present, there are naturally limits to making a large change in the capacity of personnel or making a large change in the size or form of the arena court. Therefore, although sports events for tens of thousands of people, such as soccer, can be optimally performed, it is not possible to perform other events with completely different sizes and personalities, such as classical music concerts, in the optimal environment. It was For this reason, in planning the arena, the reality is that measures are still being explored to enable such things.

The present invention has been made in view of the above circumstances, and it is possible to widely and easily change the form of the accommodation personnel, the seating arrangement, and the arena court, and if necessary, it is different. The aim is to provide an effective facility where it is possible to hold events simultaneously.

[0006]

In order to achieve the above object, the present invention is a complex arena in which a hall is arranged adjacent to an arena for holding various events, wherein the arena is a staircase around the arena court. The stand is provided, and the entire stand located between the arena and the hall is a rotatable stand capable of horizontal rotation, and the rotatable stand is moved from the state facing the arena to the hole. The rotating stand is also used as a seat for the hall by horizontally rotating it so that it faces the surface, and the rotating stand is integrally provided with a frame forming a wall surface or a ceiling surface of the hole. It is characterized by.

In the composite arena of the present invention, it is provided with a levitation mechanism for levitating and supporting the entire rotation stand from its supporting floor surface, and a rotation mechanism for rotating the rotation stand levitated by the levitation mechanism, As the levitation mechanism, a structure in which the bag is expanded by compressed air to float the rotating stand and an air film is formed between the bag and the supporting floor surface by the air flow ejected from the bag. Is preferred. Then, a support shaft that supports the rotation center position of the rotation stand so as to be rotatable and displaceable in the vertical direction is fixed to the support floor surface, and the support shaft serves as a hollow shaft inside the bag body of the levitation mechanism. It is conceivable to incorporate an air pipe for supplying compressed air into the.

In the composite arena of the present invention,
The skeleton for partitioning the arena and the hole in the arena is provided, and the skeleton and the skeleton provided in the rotating stand are mutually continuous to partition the arena and the hole, Further, a seal mechanism is provided to close the gap between both the skeletons when the rotating stand faces the arena and the hole, and the seal mechanism is interposed between the skeletons and expands normally. It is preferable that the elastic tube is pressure-bonded to both the frames and is made of an elastic tube that contracts when the rotating stand is horizontally rotated to allow the rotation. And, for example, when the space between both the skeletons is changed when rotating the rotary stand, the elastic tube is fixedly provided to one skeleton and the other skeleton is attached to the elastic tube. A plate that can be brought into close contact is provided so as to be movable in a direction in which it separates from and comes in contact with the elastic tube, and is capable of being pressed against the elastic tube by a pressing mechanism. It is conceivable to provide a sealing material that closes the gap between the plate and the frame.

Further, at least a part of the other stands provided in the arena can be moved up and down and can be slid so as to advance and retreat in the arena court direction, and a roof covering the entire arena is provided and a large number of ceiling plates are provided from the roof. It is conceivable to suspend and support each of them independently so that they can be raised and lowered and tilted.

[0010]

The composite arena of the present invention has a form in which the arena and the hall are arranged adjacent to each other. However, rather than providing them in an independent form, a part of the stand of the arena is used as the seats and structure of the hall. It is also used.
That is, of the stands on the side of the arena, the entire stand on the side of the hall is a rotating stand that can rotate horizontally, and the body that will be the wall surface and ceiling surface of the hall is integrally provided on the stand, except for the stage part. The structure that constitutes the main part of Then, turn the rotating stand 180 degrees toward the hall from the state of facing the arena.
By rotating it horizontally, the rotating stand becomes a seat facing the hall.

The scales of the arena and the hall can be set as appropriate. To give a concrete example, for example, when an arena for 30,000 people and a hall for 5,000 people are provided, the arena has a capacity of 30,000 seats. With a stand,
Among them, the stand for 5,000 seats located on the hall side will be a rotating stand that can rotate horizontally. In this case, not only is it possible to hold a large-scale sporting event with a maximum capacity of 30,000 in the arena, but a hall that can accommodate 5,000 people can be separated from the arena by rotating the above rotating stand half a turn. This allows the establishment of relatively small events such as classical music concerts independently. At this time, the arena stand has 25,000 seats, and even in that state, the event can be carried out without any trouble. In other words, in this case, a relatively small-scale event of about 5,000 people, a medium-scale event of about 25,000 people, and a large-scale event of about 30,000 people can be carried out in optimal conditions. .

[0012]

Embodiments of the present invention will be described below with reference to the drawings. The facility of the present embodiment is a complex arena in which an arena A having about 30,000 stand seats and a hall H having about 5,000 seats are arranged adjacent to each other, but in the facility of this embodiment, arena A and hall H are used. Are not independent, but a part of the stand of the arena A is a rotating stand which is also used as a seat for the hall H. Further, another part of the stand of the arena A is a slide stand that can be moved up and down and slidable in the direction of the arena court. Further, a large number of vertically movable and tiltable ceiling plates forming a virtual ceiling surface of the arena A are provided. Has been provided.

That is, as shown in FIGS. 1 to 5, the arena A in this embodiment has a substantially elliptical shape in plan view, and a stair-like stand 2 (2a, 2a, 2b, 2c) are provided over three floors, and for example, 30,000 seats are secured for the stands 2 as a whole.
The second-floor stand 2b and the third-floor stand 2c are fixedly installed in the three directions except the side, and the first-floor stand is a slide stand 2a that can be moved up and down and slidable so as to move forward and backward toward the arena court 1. On the other hand, on the hall H side, the third-floor stand 3 is fixedly installed, but the lower two-tiered stand is a rotation stand 4 in which the whole of them is horizontally rotatable in order to serve as the hall seats of the hall H. Has become. Further, as shown in FIG. 1, the facility of the present embodiment is almost entirely covered by a truss roof R except a part of the hall H, and a large number of ceiling plates 5 are suspended from and supported by the truss roof R. It has become a thing.

First, the rotary stand 4 will be described in detail. The rotating stand 4 is a structure which itself constitutes the main part of the hall H (excluding the stage part), and
And a skeleton 11 which constitutes the ceiling surface of the hall H,
A frame 12 which is curved in an arc shape and constitutes both side wall surfaces of the hole H, and a frame 13 which constitutes a rear wall of the hole H.
(See FIGS. 3 and 5), and a stand with, for example, about 5,000 seats is provided in two levels inside the hall, and behind that, hall-related facilities such as stairs, lobby, and toilet are provided. It is a thing. A frame 14 for supporting the whole is provided on the bottom surface of the rotation stand 4, and the rotation stand 4 is provided with the frame 14 through the frame 14.
Is supported as a support floor. Also,
A levitation mechanism 16 and a rotation mechanism 1 for horizontally rotating the support stand 15 around the frame 14 with the entire rotation stand 4 slightly levitated from the arena coat 1.
7 is incorporated.

The support shaft 15 is fixedly provided on the arena coat 1 as shown in FIG. 7, and the frame 14 is rotatable by a bearing 51 and vertically by a slide mechanism 52. It is supported in a displaceable state.

Further, the levitation mechanism 16 in this embodiment is
As shown in FIGS. 6 to 10, a large number of inflatable / contractible annular bag bodies 16a are attached to the bottom surface of the arc-shaped sub-frame 14a that is triple-attached to the bottom surface of the frame 14, and these bag bodies 16a are attached. A so-called air caster (sometimes referred to as an air bearing) of a type in which the whole is floated by supplying compressed air and expanding it is adopted. The air caster as the floating mechanism 16 is shown in FIG.
As shown in FIG. 0 (a), normally, the bag 16a is contracted to directly support the rotation stand 4 on the arena coat 1 through the frame 14 in a stationary state. 4 is rotated, as shown in FIG.
As shown in (b), compressed air is supplied to the bag body 16a to expand it, thereby slightly floating (for example, about 90 mm) the rotating stand 4 and being formed inside the bag body 16a. By ejecting the airflow from the jet outlet 16b, the jetted airflow is caused to flow out from the bottom surface of the bag body 16a to the outside, and an air film is formed between the bag body 16a and the floor surface of the arena coat 1. The sliding resistance of is greatly reduced. Therefore, in such a levitated state, the rotation stand 4 can be easily and quickly rotated with a small driving force, and no guide rails are required, and noise generated during rotation is extremely low. It can be small and very effective.

Further, the rotating mechanism 17 in this embodiment is
As shown in FIGS. 6 and 11, a rack and pinion mechanism including an arcuate rack 17a provided on the bottom surface of the frame 14 and a pinion 17c that meshes with the rack 17a and is rotated by a hydraulic motor 17b is employed. Reference numeral 17d shown in FIG. 11 is an idle pinion that supports the rack 17a.

As shown in FIG. 7, the support shaft 15 is a hollow shaft, and an air pipe 16e for supplying compressed air to the bag body 16a is incorporated in the support shaft 15. Has been. As the air pipe 16e, a flexible hose is adopted so as not to restrain the rotation of the rotary stand 4, and the support shaft 15 is inserted to be connected to the compressor 16f installed under the floor of the arena coat 1. . Alternatively, instead of using a hose as the air pipe 16e, a collective air pipe 16c is fixedly incorporated in the support shaft 15 as shown in FIG.
Each air pipe 16e through the rotary joint 16d attached to c
It is also possible to distribute compressed air to.

Further, for the rotation stand 4, the air pipe 1
It is necessary to connect not only 6e, but also various equipment flow lines, that is, electric wiring, water supply / drainage pipes, ducts, etc., but these flow lines also do not restrain the rotation of the rotation stand 4 like the air pipe 16e. Support shaft 1 with flexibility
5 may be inserted or may be connected via an appropriate rotary joint. Alternatively, a flow line connected when the rotation stand 4 faces the arena A and a flow line of two systems connected when the rotation stand 4 faces the hole H are prepared, and the connection is changed when rotating. Just do it. Reference numeral 60 shown in FIG. 7 indicates an electric cable passed through the support shaft 15, and 61 indicates a power supply facility.

By the way, in the facility of the present embodiment, the arena A and the hall H are so arranged that the rotating stand 4 faces the arena A and the hall H so that the arena A and the hall H can be used independently. And are divided by a skeleton, and a seal mechanism 6 is interposed between the skeletons.

That is, inside the arena A, sleeve walls 18 are provided on both sides of the rotation stand 4, and when the rotation stand 4 faces the hole H side (see FIG. 5), the sleeve walls 18 are provided. The sleeve walls 18 and 18 and the rear wall 13 of the rotary stand 4 are continuous with each other, and the arena A and the hole H are partitioned by the sleeve walls 18 and 18 and the rear wall 13. On the other hand, when the rotation stand 4 faces the arena A (see FIG. 3), the sleeve walls 18 and 18 and the side walls 12 and 12 of the rotation stand 4 are continuous with each other, and the sleeve walls 18 and 18 are By the side walls 12, 12 and the rear wall 13 of the rotation stand, the internal space of the rotation stand 4 integrated with the arena A and the outside thereof are partitioned. It should be noted that regardless of whether the rotating stand 4 faces the arena A or the hall H, the frame 11 that constitutes the ceiling surface of the rotating stand 4 and the third-floor stand 3 of the arena A located above the structure 11 are located. Is continuous with the floor surface (see FIGS. 2 and 4), and the arenas A and the halls H are also partitioned by them.

The above-mentioned sealing mechanism 6 is interposed between the frames of both the arena A and the rotary stand 4 to close the gap between them and ensure sound insulation performance.
The sealing mechanism 6 in this embodiment is shown in FIGS.
An elastic tube 6a capable of expansion and contraction and a plate 6b with which the elastic tube 6a is in close contact, for example, a metal plate such as a stainless plate is used.

The elastic tube 6a is a hollow tube made of an elastic material such as neoprene rubber and is attached to the sleeve wall 18 and the floor surface of the third floor stand 3 in two steps. These elastic tubes 6a are normally in a state of being expanded by their own elastic force, and the side walls 1 of the rotation stand 4 correspond to their mounting positions.
2 and the plate 6b provided on the ceiling surface 11, and the gap is completely closed there to ensure excellent sound insulation performance. Further, when the rotation stand 4 is rotated, the elastic tube 6a is evacuated through the exhaust pipe 6c to contract it, thereby ensuring a gap between both the skeletons and allowing the rotation stand 4 to rotate. It is supposed to do.

When the rotary stand 4 is rotated, the rotary stand 4 is slightly floated by the levitation mechanism 16 as described above, so that it corresponds to the elastic tube 6a attached to the floor surface of the third floor stand 3. Rotating stand 4
The plate 6b attached to the ceiling surface 11 of the link 6d and the spring 6 in the groove formed in the ceiling surface 11 of the rotation stand 4 as shown in FIG.
It is attached so as to be vertically displaceable by e. Then, when the rotary stand 4 is floated to rotate, the plate 6b is pulled down by the link mechanism 6d to allow the floating, and after the rotation is completed and the rotary stand 4 is allowed to stand still on the arena coat 1, the plate is released. 6b
Is pushed up and the spring 6e presses against the elastic tube 6a for sealing. A sealing material 6f made of neoprene rubber or the like is attached to the inside of the groove portion, and when the plate 6b is pushed up, its edge is pressed by the sealing material 6f to ensure sound insulation. . Of course, as the plate 6b, one having excellent sound insulation is used.

As a mechanism for vertically displacing the plate 6b, an air cylinder 6g as shown in FIG. 15 is used instead of the link mechanism 6d as described above.
(Or a hydraulic cylinder) can also be used.
FIG. 15A shows a state in which the rotary stand 4 is floated to rotate, and FIG. 15B shows a state in which the rotary stand 4 is left stationary on the arena coat 1 to perform sealing.

In the facility of this embodiment equipped with the above-described rotary stand 4, the rotary stand 4 is only rotated half a turn according to the event to be held, and the rotary stand 4 is moved to the arena A or the hall H. The optimum use form for facing any of the above can be selected. For example, when holding a large-scale sporting event or a rock concert in Arena A, the rotation stand 4 faces the Arena A side, and the maximum number of persons accommodated (30,000 in the above embodiment). The usage pattern may be exactly the same as in the case of a normal arena. On the other hand, when conducting a relatively small event such as a classical concert,
If this is done in the arena A, the accommodation personnel and space volume are too large, and the atmosphere does not match, so in that case, the rotation stand 4 is rotated half a turn so as to face the hole H, and it is optimal in the hole H where the space volume is moderate. It should be held in an environment.

When the rotating stand 4 is used as the hall H, the capacity of the arena A is reduced, but if necessary, the arena A in that state is reduced.
You can also hold other events at the same time.
Also in that case, the arena A and the hall H are partitioned by the skeleton, and the sound insulation performance is secured by the seal mechanism 6, so that one event does not adversely affect the other event. A rollback stand 24, which will be described later, is incorporated in the back surface of the rotation stand 4, and when the rotation stand 4 is used facing the hole H, it is pulled out to the arena court 1 side.

The rotating stand 4 has been described above. Next, the slide stand 2a will be described.
As described above, in the facility of this embodiment, the arena A
The first floor stand in the can be lifted and arena court 1
The slide stand 2a is slidable so as to move back and forth in the direction of, so that the capacity of the arena A and the seating arrangement of the arena can be widely changed according to the event, and the form of the arena court 1 can be greatly changed. Has become.

The slide stand 2a will be described in detail. As shown in FIG. 17, the slide stand 2a normally retreats to a position below the second floor stand 2b to form a first floor stand. The stand 2a can be moved up and down by a hydraulic cylinder (elevating mechanism) 21, and is lifted as shown in FIG. 16 to be separated from the hydraulic cylinder 21 and supported by an automatic locking device (supporting mechanism) 22. ing. The hydraulic cylinder 21 of the automatic lock device 22 is the slide stand 2a.
Is extended as it is raised, and is naturally locked at the rising limit position to support the slide stand 2a in a floating state at that position. In addition, on the bottom surface of the automatic lock device 22, an air caster similar to that used for floating the rotation stand 4 is incorporated,
The slide stand 2a can be easily slid and moved forward and backward toward the arena court 1 while the slide stand 2a is supported in a floating manner. The slide mechanism 23 for advancing and retracting the slide stand 2a is, as shown in FIG. 16, a rack 23a provided on a side portion of the slide stand 2a and a rack formed by a pinion 23c meshed with the rack 23a and rotated by a hydraulic motor 23b. The pinion mechanism is adopted.

Then, as described above, the slide stand 2
When a rises and advances to Arena Court 1 side,
As shown in FIG. 18, the slide stand 2a and the second-floor stand 2b are continuous to form a series of step-like stands. Further, the roll-back stand 24 is provided in front of the slide stand 2a in that state.
And the passenger seat units 25 are continuously arranged so as to form a series of stairs, whereby the arena court 1
While securing space for events such as boxing, sumo, basketball, and volleyball in the central part of the room, you can secure a large number of staircases around it, resulting in an easy-to-see and close-to-event atmosphere. It is possible to create the number of seats and the event space suitable for the event with a certain optimum viewing distance.

The rollback stand 24 and the passenger seat unit 25 are adjusted in height by a lifter 26 according to their installation positions. In addition, the passenger seat unit 25 is stored in an automatic storage 27 provided under the floor of the arena court 1 when not in use, and is automatically transported to a predetermined position by an automatic transport mechanism (not shown) so as to be installed. It has become. Its automatic storage 2
7 are concentrated in two places, so there are few restrictions when using Arena Court 1, and most of the underfloor space can be used for other purposes such as equipment pits, and a sufficient floor load can be secured. This is possible, which is advantageous over disposing a large number of automatic storages over the entire arena court 1. Further, when the slide stand 2a is raised and moved forward, the bridge 28
Is lifted by the lifter 29 to secure a passage for connecting the stand 2 and the lobby.

The rotating stand 4 and the slide stand 2a have been described above. Next, the ceiling plate 5 for forming the virtual ceiling surface of the arena A will be described.

As shown in FIGS. 19 and 20, each ceiling plate 5 is provided with a sound absorbing plate 32 on the lower surface side of the main frame 31, a three-primary-color lighting fixture 33 for effecting the color change of the ceiling plate 5 itself, The acoustic reflector 34 is attached.
The ceiling boards 5 are suspended and supported from the truss roof R by three wire ropes 35 via a suspension frame 36, and each wire rope 35 is installed on a catwalk 37 provided on the truss roof R. By being wound by the winch 38, each ceiling plate 5 can be independently moved up and down and tilted to freely change its posture.

The ceiling plate 5 in this embodiment is formed by combining triangular shapes corresponding to the shape of the truss roof R, and is curved slightly downward, but the shape is arbitrary. Further, reference numeral 40 shown in FIGS.
Is an elevating truss having a triangular cross section on which a lighting fixture, a speaker, and other equipment are mounted, and is suspended and supported from a truss roof R so that it can be independently moved up and down and tilted similarly to the ceiling board 5. Although not shown, various batons used for event production are similarly set on the truss roof R.
It can be appropriately provided so that it can be moved up and down.

In the arena A of this embodiment provided with the ceiling board 5 as described above, the height and posture of each ceiling board 5 are adjusted according to the kind and scale of the event to be held and the arrangement of the seats. As a result, the substantial ceiling height and the form of the ceiling surface can be freely changed, and the acoustic characteristics can also be changed. For example, in the case of a large-scale sporting event, it is sufficient to raise all ceiling plates 5 to a position directly below the truss roof R so that the ceiling height of the entire arena A does not interfere with the event. In addition to being able to secure a large amount, it is possible to secure a large volume space suitable for holding a large-scale event. In this case, the substantial space volume of the entire arena A becomes maximum, and normally the reverberation time becomes maximum in this state.

On the other hand, when performing a small-scale event, if the ceiling height is too large, the atmosphere may not be suitable, and the reverberation time may be too long and the acoustic clarity may be impaired. In this case, each ceiling plate 5 can be lowered to reduce the substantial ceiling height so that the space volume can be reduced to suit the event. Also, by doing so, the acoustic characteristics can be improved so as to match the content of the event. That is, by lowering the ceiling plate 5 as a whole to reduce the ceiling height substantially, the acoustic energy inside the arena A is increased and the feeling of volume is increased, and especially the energy density of the initial reflected sound is increased and the sound is clear. It has an improved effect and an excellent diffusion effect, which is a favorable environment for relatively small-scale events.

Of course, depending on the event, the acoustic characteristics are given the highest priority, and the height and posture of each ceiling board 5 are adjusted, or the ceiling surface is set to a complicated shape in accordance with the production of the event. Each ceiling board 5 is appropriately moved up and down, or the color of each ceiling board 5 is changed every moment by the three primary color illumination 33.
You can freely do such things. In addition, depending on the event, it may be assumed that seats are reserved in the arena court 1 and the second floor stand 2b or the third floor stand 2c is not used. In that case, as shown in FIG. By lowering and setting the substantial ceiling height to the position of the second-floor stand 2b, the unused second-floor stand 2b and above can be hidden above the ceiling surface.

Although one embodiment of the present invention has been described in detail above, the gist of the present invention resides in that the rotating stand 4 is provided so that a part of the stand of the arena A is also used as a seat for the hall H. The specific structure of the rotation stand 4,
For example, its scale, form, levitation mechanism 16 and rotation mechanism 1
7. The details of the seal mechanism 6 and the like are not limited to the above embodiment, and various design changes can be made. Further, the configuration of the parts other than the rotation stand 4 can be arbitrarily changed. For example, the slide stand 2a
The ceiling plate 5 and the ceiling plate 5 are preferably used together with the rotating stand 4, but they are not necessarily provided side by side and may be omitted.

[0039]

As described above, the composite arena of the present invention has a structure in which the arena and the hall are arranged adjacent to each other and the rotation stand is horizontally rotatable between them to hold the event to be held. Depending on the type and scale of the arena, a hole that doubles as a part of the stand of the arena can be established only by rotating the rotating stand a half turn. Therefore, the event can be performed in the optimal environment in the arena and the hall. At the same time, it is possible to change the capacity and the seating capacity of the arena, the scale and form of the arena space widely and easily, and it is also possible to hold different events at the same time in the arena and the hall if necessary.

In particular, if a mechanism for rotating the rotary stand in a state of being floated by compressed air is employed for horizontally rotating the rotary stand, it is possible to easily and quickly rotate the rotary stand with a low driving force. In this case, if the rotation center position of the rotation stand is supported by the support shaft and the air tube is incorporated into the support shaft, the position of the rotation stand can be restrained and the air tube does not hinder the rotation. .

Further, by partitioning the arena and the hall by the skeleton and interposing a sealing mechanism made of an elastic tube between the skeletons, a sufficient sound insulation performance between the arena and the hall can be ensured and used simultaneously. It doesn't hurt. In this case, by making the plate in close contact with the elastic tube detachable and pressable with respect to the elastic tube, it is possible to cope with the case where the distance between the frames in which the seal mechanism is interposed changes. .

Further, if the other stand of the arena is a slide stand which can be moved up and down and slidable, the form of the arena accommodation staff and the stand and the arena coat can be changed more broadly and freely, and can be raised and lowered independently. By suspending and supporting a large number of tiltable ceiling plates from the roof surface, it is possible to freely form an arbitrary ceiling height and an arbitrary form virtual ceiling surface corresponding to an event or seat arrangement by the ceiling plates.
