Description

【0001】
【発明の属する技術分野】
本発明は、イベントを開催するための空間を構成するドーム等の構造物に係り、特に、開催するイベントの規模に合わせて空間気積を変化可能な構造物に関するものである。
【0002】
【従来の技術】
従来、イベントを開催する構造物としては、ドーム等の構造物がある。この構造物においては、開催するイベントの規模に合わせて使用する空間気積を変える場合、構造物内に複数の仮設の間仕切壁を設置することで、当該ドーム内の空間を所定の形状に仕切り、例えばボクシング観戦や野球観戦等の使用するイベントに合わせた規模のイベント空間を確保していた。
【0003】
【発明が解決しようとする課題】
しかしながら、上記仮設の間仕切壁で構造壁内の空間を仕切る方法においては、その仮設の間仕切壁の配置の仕方によっては、構造物内の空間を二つに区画することはできるが、上記仮設の間仕切壁で区画された、構造物内の二つのエリア同士を独立させることが困難である。また、仮設の間仕切壁だけで区切られるだけでは、一方のエリアで火災等の災害が生じた場合に、その煙や火などが隣りのエリアに移りやすく防災上問題がある。なお、上記仮設の間仕切壁は、目的としたイベントが終了したら撤去する必要がある。
【0004】
このように、上記のような従来の空間気積が変更可能な構造物では、異なる種類の2つのイベントを同時に開催することはできないという問題がある。
本発明は、上記のような問題点に着目してなされたもので、空間気積が変更可能で且つ二つの異なるイベントが同時に開催することができる構造物を提供することを目的としている。
【0005】
【課題を解決するための手段】
上記目的を達成するために、本発明のうち請求項1に記載した空間気積を変化可能な構造物は、所定の空間を囲む外周構造壁と、その外周構造壁内の空間を区画し且つ横方向端部が上記外周構造壁内壁に摺接又は近接した状態を維持したまま移動するように水平移動可能となっており当該移動につれて上記区画したエリアの空間気積を変更する移動構造壁と、該移動構造壁の両側にそれぞれ設けられ、一端部が上記移動構造壁に支持され他端部が上記外周構造壁の内壁に着脱自在に固定される界壁と、を備え、上記移動構造壁の横方向端部側壁面と上記外周構造壁の内壁と上記界壁とによって囲まれた防災上の緩衝空間を形成することを特徴とすることを特徴とするものである。
【0006】
また、請求項2に記載した発明は、請求項1に記載された構成に対して、上記界壁は、移動構造壁に回転可能に軸支され当該移動構造壁から横方向に旋回可能となっていて、閉じた状態では上記移動構造壁に着脱自在に固定され、開いた状態では上記防災上の緩衝空間を形成することを特徴とする。
【0007】
【作用】
請求項1に記載された発明においては、外周構造壁内の空間は、移動構造壁によって独立した二つのエリアに区間される。上記移動構造壁は、その横方向端部が外周構造壁内壁に沿って移動するように水平移動可能なので、その移動構造壁は、上記外周構造壁内を二つの区画に分離した状態を維持したまま移動することができる。このため、上記移動構造壁の位置を変更させることで、当該移動構造壁によって区画された二つのエリアは、互いに独立した状態で各空間気積が変更される。
【0008】
このとき、上記移動構造壁から外周構造壁の内壁に向けて界壁が延設されることで、移動する移動構造壁と外周構造壁との接続部分近傍に対して、その移動構造壁の横方向端部側と外周構造物の内壁と上記界壁とによって囲まれた、所定の防災上の緩衝空間が確保される。
この結果、上記二つのエリアは防災上独立した空間を構成可能となり、一つの外周構造壁内で二つの異なったイベントを同時開催することが可能となる。また、上記界壁は、移動構造壁と外周構造壁との接続部分を隠す役割も持つ。
【0009】
なお、上記界壁は、移動構造壁に支持されているために、その移動構造壁の移動に追従して自動的に移動する。従って、当該移動構造壁を移動させる度に独立して界壁の位置を移動させる作業は必要ない。
また、請求項2に記載した発明においては、上記界壁が移動構造壁から横方向に旋回可能となっているので、その界壁を外周構造壁側に開くことで、上記のような防災上の緩衝空間が確保される。
【0010】
さらに、請求項2の発明では、界壁を外周構造壁側から移動構造壁側に旋回させて当該移動構造壁に当接又は近接するように当該界壁を閉じることが可能となる。これによって、一方のエリアの空間気積のみを大きくして使用するために、当該移動構造壁を、上記界壁が設けられている壁面側が外周構造壁内面に近接するまで移動させても、上記界壁が障害とならずに、上記移動構造壁を十分に外周構造壁内壁に近接させることが可能となる。
【0011】
また、上記界壁によって、界壁が設けられている空間を整形するという作用も有する。
【0012】
【発明の実施の形態】
上記発明の実施の形態を図面に基づいて説明する。
本実施の形態の構造物は、屋根を省略した斜視図である図1、及び構造物の壁部分の概念図である図2に示すような構成となっている。即ち、横断面略円環形状をなす内周側構造壁1の外周に外周構造壁4が配設されて構成されている。
【0013】
上記内周側構造壁1は、それぞれ略半円筒形状をした固定構造壁2と移動構造壁3とから構成され、その固定構造壁2の端部と移動構造壁3の端部とを対向配置することによって所定の空間気積を囲むようになっている。
さらに、上記移動構造壁3は、図示しない公知の車輪機構を備え、その車輪機構を駆動することで、地面に敷設された移動レール16に沿って、外方に向けて水平移動可能となっている。なお、移動構造壁3は、防音対策などのために二重壁構造となっている。また、上記移動レール16は図中2本しか図示されていないが、実際には、移動構造壁3の重量との兼ね合いでもっと多くのレールが敷設される。
【0014】
また、上記外周構造壁4は、横断面略U字形状のU字構造壁5と、三日月状の円弧状構造壁6とから構成されている。
上記U字構造壁5は、その中央部分5aが、上記内周側構造壁1の固定構造壁2の外周に沿って配設されて半円筒状に形成されていると共に、その半円筒状の中央部分5aの両端部に連続する部分5b(以下、足部と呼ぶ)が、それぞれ上記移動構造壁3の移動方向に沿って延設されている。これによって、上記移動構造壁3は、その横方向両端部3aがそれぞれ上記外周構造壁4の足部5bの内壁に摺接又は近接した状態を維持したまま、当該足部5bに沿って水平移動可能となっている。
【0015】
また、上記U字構造物5の両足部5bの先端部間を連結するように、上記円弧状構造壁6が配設されている。その円弧状構造壁6の内壁面は、上記移動構造壁3の外壁面に対して当該移動構造壁3の移動方向に所定間隔を空けて対向していて、上記移動構造壁3が最大限後退した際に、その移動構造壁3の外壁面は円弧状構造壁6の内壁面に近接可能となっている。
【0016】
上記構成によって、外周構造壁4で囲まれる横断面略楕円形状の空間が、上記移動構造壁3によって二つのエリアA,Bに区画され、さらに、該移動構造壁3が進退することによって各エリアA,Bの空間気積が変化するようになる。
また、上記移動構造壁3の外壁側には、一対の界壁7が取り付けられている。各界壁7の横方向一端部側は、図3及び図4に示すように、一対のヒンジ8を介して上記移動構造壁3に回転可能に軸支され、横方向に旋回可能となっている。なお、上記図3は界壁7が開いた状態を、また、図4は界壁7が閉じた状態を示している。
【0017】
その界壁7の壁面形状は、図3に示すように、該移動構造壁3の外壁に沿った曲面形状をしていて、移動構造壁3側に旋回させた状態では、当該移動構造壁3内に収納可能となっている。
また、上記界壁7の横方向他端部側には、ロックピン機構9が三箇所,設けられている。このロックピン機構9は、それぞれ軸を水平にしたロックピン9aが、筒部材等からなる案内部材9bによって軸方向にのみ進退可能に規制されていると共に電動シリンダ9cによって軸方向に進退させられるように構成されている。このロックピン機構9によって、界壁7の横方向他端部側は、閉じた状態では移動構造壁3の外壁に、また、開いた状態では外周構造壁4内壁にそれぞれ、着脱自在に固定されるようになる。
【0018】
さらに、上記界壁7の下端部にもアウトリガ・ロック機構10が設けられている。このアウトリガ・ロック機構10は、軸を上下に向けた軸の下端部に挿入体10aを備え、シリンダ装置によって上記挿入体10aを昇降させる機構となっている。そして、地面に形成された凹部11に上記挿入体10aを挿入することで界壁7が拘束されるようになっている。
【0019】
また、上記界壁7の下端部には、2つの車輪12,13が取り付けられていて、地面に敷設された所定のレール14上を転動可能となっている。その2つの車輪12,13のうちの一方13は駆動輪であって、その駆動輪は、電動モータ15によって駆動されるようになっている。
なお、上記構造物の図示しない屋根は、図1中の一点鎖線で示す位置Cに配設される図示しない一対の柱部材と、上記U字構造壁5の中央部分である円筒形状の部分5aとで支持される構造となっている。これによって、上記移動構造壁3は、屋根を支持することなく移動することが可能となっている。
【0020】
次に、上記構造物の作用等について説明する。
ここで、下記の説明では、外周構造壁4で囲まれる空間のうち、内周側構造壁1の固定構造壁2と移動構造壁3との間にある空間をエリアAと呼び、また、移動構造壁3と円弧状構造壁6との間にある空間をエリアBと呼ぶ。
上記のような構成の構造物では、通常時には、主なイベント空間であるエリアAにおいて各種のエベントを開催する。そして、両エリアA,Bで異なるイベントを開催する場合には、図1及図2に示すように、一対の界壁7を横方向にそれぞれ開き、その横方向他端部を外周構造壁4の足部5b内壁に対してロック機構9によって拘束して、当該各界壁7を固定する。
【0021】
これによって、移動構造壁3によって区画される両エリアA,B間の接続部分である、U字構造壁5の足部5b内壁と移動構造壁3の外周壁と界壁7との間に、防災上の所定の緩衝空間が形成されて、両エリアA,Bが防災上も含めて独立した空間を構成するようになる。つまり、一方のエリアで火災等が生じても、上記界壁7で構成する緩衝空間によって、他方のエリアへの火災や煙の移動が抑制される。
【0022】
この結果、両エリアA,Bで個々に異なるイベントを同時に開催することが可能となる。勿論、両エリアA,Bで連関するイベントを開催してもよいし、両エリアA,Bでのイベントを同時に開催しなくてもよい。
また、上記のように界壁7をエリアBの空間に向けて広げることで、移動構造壁3の横方向両端部分3aが隠されると共に、エリアBの空間が横断面略楕円形状の閉じた空間となる。この結果、当該エリアBは、自立性が強調された空間となる。
【0023】
なお、上記界壁7の円弧状構造壁6を向く面側に映像スクリーン等の大型映像装置を装備させて、色々な演出を可能としてもよい。
また、エリアA側の空間気積を広くして使用したい場合には、図5に示すように、移動構造壁3を走行レール16に沿って所定量だけ後退させることで、当該エリアA側の空間気積を拡大する。
【0024】
さらに、エリアA側の空間気積を最大まで広げて使用する場合には、先ず、各界壁7を移動構造壁3側に旋回させるように閉じて上記各界壁7を移動構造壁3の外周面に収納する。その後に、図6に示すように、移動構造壁3を移動レール16に沿って後退させて、当該移動構造壁3の外壁を円弧状構造壁6の内壁に近接させる。
【0025】
これによって、エリアBの空間気積はゼロに近くなり、エリアAの空間気積が最大の状態で使用可能となる。このとき、上記実施の形態のように緩衝空間を確保するための界壁7を設けても、エリアBを使用しない時には、上記界壁7は、閉じるように旋回させることで移動構造壁3内に収納されて、上記のように移動構造壁3の外壁を円弧状構造壁6の内壁に近接させてエリアAの空間気積を最大に設定する際の邪魔となることはない。
【0026】
また、上記界壁7は、移動構造壁3に支持されているので、移動構造壁3を移動するだけで一緒に移動して、移動構造壁3を移動させる度に上記界壁7の位置を移動させる必要がなく、界壁7に設けた外周構造壁4とのロック機構を一時的に解除して、移動終了後に再びロック機構を作動させて拘束状態とするだけでよい。
【0027】
なお、上記実施の形態では、移動構造壁3が直線状態に水平移動して、当該移動構造壁3の横方向両端部3aが、それぞれ移動構造壁3の足部5bに沿って移動する形式の構造物の例で説明したが、本発明は、このような形式の構造に限定されるものではなく、例えば、図7に示すように、移動構造壁3は、その横方向一端部側3cのみが外周構造壁4内周に沿って移動するように、つまり、該移動構造壁3の横方向他端部側3dを中心に旋回するよう水平移動可能な構成の構造など、他の構造となっていてもよい。要は、移動構造壁3によって、二つの独立したエリアA,Bが確保可能で且つ、両エリアA,Bの空間気積が変化できる構造となっていればよい。
【0028】
また、上記実施の形態では、移動構造壁3に区画される二つの空間のうちエリアAが主なイベント空間を構成し、エリアBが副のイベント空間を構成するような構造物で説明しているが、構造物はそのような構成に限定されるものではなく、例えば、図8に示すように、移動構造壁3が真っ直ぐな壁から構成され、その移動構造壁3で区画される2つの空間が対等な関係となっている構造物であってもよい。
【0029】
ここで、上記図8に示す構造物では、移動構造壁3の両壁面にそれぞれ、防災上の緩衝空間を構成可能な界壁7を設けた図を示しているが、前記実施の形態と同様に、一方の壁面側にのみ界壁7を設ける構造であってもよい。
また、上記全実施の形態では、界壁7を移動構造壁3に旋回可能に軸支させた構造としているが、必ずしも旋回可能な構成とする必要はなく、該移動構造壁3から所定角度を持って外周構造壁4側に延びた状態で上記界壁7を固定してもよい。但し、この場合には、移動構造壁3を移動させて、一方のエリアの空間気積を潰して他方のエリアを大きくなるようにしても、上記界壁7の突出分だけ移動構造壁3と外周構造壁4との間を詰めることができず、その分だけ、他方のエリアの最大空間気積が制限されて小さくなる。
【0030】
【発明の効果】
以上説明してきたように、本発明の空間気積を変化可能な構造物においては、移動構造壁によって空間気積を変化可能な独立した二つのエリアが確保されると共に、界壁によって両エリア間の間隙に防災上の緩衝空間が形成されることで、上記二つのエリアは防災上独立した空間となる。従って、一つの外周構造壁内で二つの異なったイベントを同時開催することができるという効果がある。
【0031】
このとき、請求項2に記載した発明を採用すると、上記界壁は旋回可能な構成となっているので、その界壁を移動構造壁に沿った位置に移動可能となる。従って、一方のエリアの空間気積を最小、つまり反対側のエリアの空間気積を最大とするために、移動構造壁を移動させて、その壁面を外周構造壁に近接させた場合であっても、上記界壁は邪魔となることなく上記両壁面を近接可能となり、有効に一方のエリアの空間気積だけを最大量に設定して使用することが可能となるという効果がある。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a structure such as a dome constituting a space for holding an event, and more particularly to a structure capable of changing a space volume according to the scale of the event to be held.
[0002]
[Prior art]
Conventionally, as a structure for holding an event, there is a structure such as a dome. In this structure, when the space volume to be used is changed according to the scale of the event to be held, a plurality of temporary partition walls are installed in the structure to partition the space in the dome into a predetermined shape. For example, an event space of a scale suitable for an event to be used, such as watching a boxing game or watching a baseball game, is secured.
[0003]
[Problems to be solved by the invention]
However, in the method of partitioning the space in the structural wall with the temporary partition wall, the space in the structure can be divided into two parts depending on the arrangement of the temporary partition wall. It is difficult to separate two areas in a structure separated by a partition wall. In addition, if only a temporary partition wall is used to separate the area, if a fire or other disaster occurs in one area, the smoke or fire easily moves to the adjacent area, which poses a problem in disaster prevention. It is necessary to remove the temporary partition wall when the intended event ends.
[0004]
As described above, there is a problem that two types of events of different types cannot be held at the same time in the above-described conventional structure in which the spatial volume can be changed.
SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a structure in which a space volume can be changed and two different events can be held at the same time.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, a structure capable of changing a space volume according to claim 1 of the present invention defines an outer peripheral structure wall surrounding a predetermined space, and a space in the outer peripheral structure wall; A moving structure wall that is horizontally movable so that the lateral end moves while maintaining a state of sliding contact with or close to the inner wall of the outer peripheral structure wall , and changes the spatial volume of the partitioned area as the movement proceeds. When provided on both sides of said mobile structural walls, comprising a Sakaikabe having one end and the other end portion is supported on the mobile structure walls are detachably fixed to the inner wall of the peripheral structure wall, the said mobile structure The present invention is characterized in that a buffer space for disaster prevention is formed which is surrounded by a lateral end wall surface of a wall, an inner wall of the outer peripheral structure wall, and the boundary wall .
[0006]
According to a second aspect of the present invention, in the configuration according to the first aspect, the boundary wall is rotatably supported by the moving structure wall and can be turned laterally from the moving structure wall. In a closed state, it is detachably fixed to the movable structure wall, and in an open state, the buffer space for disaster prevention is formed .
[0007]
[Action]
In the invention described in claim 1, the space in the outer peripheral structure wall is sectioned into two independent areas by the moving structure wall. Since the moving structure wall is horizontally movable so that its lateral end moves along the inner wall of the outer structure wall, the moving structure wall maintains a state where the inside of the outer structure wall is separated into two sections. You can move as it is. For this reason, by changing the position of the moving structure wall, each of the two areas partitioned by the moving structure wall has its own space volume changed independently of each other.
[0008]
At this time, the boundary wall is extended from the moving structure wall toward the inner wall of the outer structure wall, so that the boundary between the moving structure wall and the outer structure wall near the connecting portion between the moving structure wall and the inner wall of the outer structure wall. A predetermined disaster prevention buffer space surrounded by the direction end portion, the inner wall of the outer peripheral structure, and the boundary wall is secured.
As a result, the two areas can form an independent space for disaster prevention, and two different events can be simultaneously held in one peripheral structure wall. Further, the boundary wall also has a role of hiding a connection portion between the moving structure wall and the outer peripheral structure wall.
[0009]
Since the boundary wall is supported by the moving structure wall, it automatically moves following the movement of the moving structure wall. Therefore, it is not necessary to independently move the position of the boundary wall every time the moving structure wall is moved.
Further, in the invention described in claim 2, since the boundary wall is rotatable in a lateral direction from the moving structure wall, the boundary wall is opened to the outer peripheral structure wall side, so that the above-mentioned disaster prevention is achieved. Buffer space is secured.
[0010]
Further, according to the second aspect of the present invention, the boundary wall can be swung from the outer peripheral structure wall side to the movable structure wall side to close the boundary wall so as to abut or approach the movable structure wall. Thereby, in order to use only the space volume of one area enlarged, even if the moving structure wall is moved until the wall surface side on which the boundary wall is provided is close to the inner surface of the outer peripheral structure wall, The moving structure wall can be brought sufficiently close to the inner wall of the outer circumferential structure wall without the boundary wall becoming an obstacle.
[0011]
Further, the boundary wall has an effect of shaping the space where the boundary wall is provided.
[0012]

Further, three lock pin mechanisms 9 are provided on the other end of the boundary wall 7 in the lateral direction. In this lock pin mechanism 9, a lock pin 9a whose axis is horizontal is regulated by a guide member 9b made of a cylindrical member or the like so that it can move only in the axial direction, and can be moved in the axial direction by an electric cylinder 9c. Is configured. By the lock pin mechanism 9, the other end in the lateral direction of the boundary wall 7 is detachably fixed to the outer wall of the movable structure wall 3 in the closed state and to the inner wall of the outer peripheral structure wall 4 in the opened state. Become so.
[0018]
Further, an outrigger lock mechanism 10 is also provided at the lower end of the boundary wall 7. The outrigger lock mechanism 10 is provided with an insert 10a at the lower end of a shaft whose axis is directed up and down, and is a mechanism for raising and lowering the insert 10a by a cylinder device. Then, the insertion wall 10a is inserted into the concave portion 11 formed on the ground, so that the boundary wall 7 is restrained.

The structure is supported by Thus, the moving structure wall 3 can move without supporting the roof.
[0020]
Next, the operation and the like of the above structure will be described.
Here, in the following description, the space between the fixed structure wall 2 of the inner circumferential side structure wall 1 and the moving structure wall 3 in the space surrounded by the outer circumferential structure wall 4 is referred to as an area A.

Are locked by the lock mechanism 9 with respect to the inner wall of the foot 5b, and the respective boundary walls 7 are fixed.
[0021]
As a result, between the inner wall of the foot 5b of the U-shaped structure wall 5, the outer peripheral wall of the movable structure wall 3, and the boundary wall 7, which is the connection between the areas A and B defined by the movable structure wall 3, A predetermined buffer space for disaster prevention is formed, and both areas A and B constitute an independent space including for disaster prevention. That is, even if a fire or the like occurs in one area, the buffer space formed by the boundary wall 7 suppresses the movement of the fire or smoke to the other area.
[0022]
As a result, different events can be simultaneously held in both areas A and B at the same time. Needless to say, events associated with both areas A and B may be held, or events in both areas A and B may not be held at the same time.
Further, by expanding the boundary wall 7 toward the space of the area B as described above, the both end portions 3a in the horizontal direction of the moving structure wall 3 are hidden, and the space of the area B is a closed space having a substantially elliptical cross section. It becomes. As a result, the area B becomes a space where independence is emphasized.
[0023]
A large-sized image device such as an image screen may be provided on the surface of the boundary wall 7 facing the arc-shaped structure wall 6 to enable various effects.
In addition, when it is desired to use the space A on the area A side wide, the moving structure wall 3 is retracted by a predetermined amount along the traveling rail 16 as shown in FIG. Enhance the space volume.
[0024]
When the space A on the side of the area A is expanded to the maximum, the respective walls 7 are closed so as to be swiveled toward the moving structure wall 3 and the respective walls 7 are first closed to the outer peripheral surface of the moving structure wall 3. To be stored. Thereafter, as shown in FIG. 6, the moving structure wall 3 is retracted along the moving rail 16 so that the outer wall of the moving structure wall 3 approaches the inner wall of the arc-shaped structure wall 6.
[0025]
As a result, the spatial air volume in the area B becomes close to zero, and the area A can be used in a state where the spatial air volume is maximum. At this time, even when the boundary wall 7 for securing the buffer space is provided as in the above-described embodiment, when the area B is not used, the boundary wall 7 is turned so as to be closed so that the inside of the moving structure wall 3 is closed. And the outer wall of the moving structure wall 3 is brought close to the inner wall of the arc-shaped structure wall 6 as described above, so that the space A in the area A is not obstructed when it is set to the maximum.
[0026]
Since the boundary wall 7 is supported by the moving structure wall 3, the boundary wall 7 moves together only by moving the moving structure wall 3, and the position of the boundary wall 7 is changed every time the moving structure wall 3 is moved. It is not necessary to move the lock, and it is only necessary to temporarily release the lock mechanism with the outer peripheral structure wall 4 provided on the boundary wall 7, and to operate the lock mechanism again after the movement is completed to bring the lock state.
[0027]
In the above embodiment, the moving structure wall 3 horizontally moves in a straight line, and the lateral ends 3a of the moving structure wall 3 move along the feet 5b of the moving structure wall 3, respectively. Although described in the example of the structure, the present invention is not limited to this type of structure. For example, as shown in FIG. Other structures, such as a structure that can move horizontally along the inner periphery of the outer peripheral structure wall 4, that is, pivotally move around the other end 3 d in the lateral direction of the moving structure wall 3. May be. In short, it is only necessary that the moving structure wall 3 has a structure in which two independent areas A and B can be secured, and the spatial volume of the two areas A and B can be changed.
[0028]
Further, in the above-described embodiment, of the two spaces defined by the moving structure wall 3, a structure in which the area A forms a main event space and the area B forms a sub event space will be described. However, the structure is not limited to such a configuration. For example, as shown in FIG. 8, the moving structure wall 3 is formed of a straight wall, and the moving structure wall 3 is divided by the moving structure wall 3. It may be a structure in which spaces have an equal relationship.
[0029]
Here, in the structure shown in FIG. 8, a diagram is shown in which the boundary walls 7 capable of forming a buffer space for disaster prevention are provided on both wall surfaces of the moving structure wall 3, respectively. Alternatively, a structure in which the boundary wall 7 is provided only on one wall surface side may be used.
Further, in all of the above-described embodiments, the boundary wall 7 is pivotally supported on the movable structure wall 3 so as to be pivotable. However, it is not necessarily required to be configured to be pivotable. The boundary wall 7 may be fixed in a state where the boundary wall 7 extends toward the outer peripheral structure wall 4. However, in this case, even if the moving structure wall 3 is moved so that the spatial volume of one area is crushed and the other area is enlarged, the moving structure wall 3 is protruded from the moving structure wall 3 by the projection of the boundary wall 7. The space between the outer peripheral structure wall 4 and the outer peripheral structure wall 4 cannot be reduced, and the maximum space volume of the other area is limited and reduced accordingly.
[0030]
【The invention's effect】
As described above, in the structure of the present invention in which the space volume can be changed, two independent areas in which the space volume can be changed are secured by the moving structure wall, and the space between the two areas is secured by the boundary wall. By forming a buffer space for disaster prevention in the gap between the two, the above two areas become independent spaces for disaster prevention. Therefore, there is an effect that two different events can be simultaneously held within one outer peripheral structure wall.
[0031]
At this time, if the invention described in claim 2 is adopted, the boundary wall is configured to be pivotable, so that the boundary wall can be moved to a position along the moving structure wall. Therefore, in order to minimize the space volume in one area, that is, to maximize the space volume in the opposite area, the moving structure wall is moved, and the wall surface is brought closer to the outer peripheral structure wall. However, there is an effect that the two walls can be approached to each other without obstructing the boundary wall, and it is possible to effectively set and use only the spatial volume of one area to the maximum amount.
