Description

本発明は津波や洪水などの発生時に、建造物が上昇して避難場所として利用出来ると共に免震構造を備えた高さ可変な津波対応建造物に関する。   The present invention relates to a tsunami-capable building that can be used as an evacuation site when a tsunami or flood occurs and has a seismic isolation structure.

現在、津波や洪水などが発生した際は、自治体等の定めた高台の学校や公民館等の公共施設へ避難するのが一般的であるが、津波の進行速度は極めて早いため、避難する高台まで離れている住民は、避難が間に合わず、逃げ遅れて津波に飲み込まれてしまう恐れが高かった。特に海岸近くの住民は短時間で高台まで避難することが殆ど出来ず、東日本大震災に於いては多数の犠牲者が発生した。   Currently, when a tsunami or flood occurs, it is common to evacuate to public facilities such as high schools and public halls established by local governments. Residents who were far away were not able to evacuate in time and were more likely to be swallowed by the tsunami after escaping. In particular, residents near the coast could hardly evacuate to high ground in a short time, and many victims occurred in the Great East Japan Earthquake.

このため、従来から津波発生時に短時間で避難する避難用シェルターや浮上する避難用シェルター、或いは高い位置に避難場所を設けた津波避難タワー、または高架式津波避難所など多種の提案がなされている。   For this reason, various proposals have conventionally been made, such as an evacuation shelter that evacuates in a short time when a tsunami occurs, an evacuation shelter that rises, a tsunami evacuation tower with a high evacuation site, or an elevated tsunami evacuation shelter .

特に上下移動可能な津波避難建築物としては、特開2006−291691に於いて水害浮上建築物が提案されている。これは台船型浮体の上に建築物を製作すると共にそれを上昇する際に伸縮させるアンカーポールで支持する構造のものであった。この建築物としては、集会所,ホテル,レストラン,幼稚園,学校,居住用住宅等である。又、特許第3023991号に於いて建築物の浮揚システムが提案されている。これは建築構造物の基礎を構成する壁と床を備えた耐水性地階部と、耐水性地階部の垂直方向の移動を案内する複数の案内柱とを有し、耐水性地階部と建築構造物は、洪水水位の上昇によって浮揚するものであった。また耐水性地階部が垂直に移動する際に、H型鋼の案内柱に沿って回転するローラが耐水性地階部に取付けられたものであった。   In particular, as a tsunami evacuation building capable of moving up and down, a flood damage floating building is proposed in Japanese Patent Laid-Open No. 2006-216991. This was a structure in which a building was manufactured on a carrier type floating body and supported by an anchor pole that was expanded and contracted when it was raised. This building is a meetinghouse, hotel, restaurant, kindergarten, school, residential house, etc. Japanese Patent No. 3023991 proposes a building levitation system. It has a water-resistant basement with walls and floors that form the foundation of the building structure, and a plurality of guide pillars that guide the vertical movement of the water-resistant basement, and the water-resistant basement and the building structure Things were levitated by rising flood levels. In addition, when the water-resistant base part moves vertically, a roller that rotates along the guide column of the H-shaped steel is attached to the water-resistant base part.

しかしながら、特開2006−291691や特許第3023991号は、津波や洪水などが発生した際に、洪水水位の上昇によって徐々に浮揚し避難所と成す役目を果たすが、大津波の襲来時には、津波避難建築物が浮揚する前に高波に飲み込まれてしまう恐れが大いにあった。更に前記津波避難建築物は地震に対して何ら対策が施されていないのが現状である。このため、地震が発生して前記津波避難建築物に損傷を生じることにより、伸縮させるアンカーポールがスムーズに伸長できなくなる恐れを生じ、或いはH型鋼の案内柱が傾いて耐水性地階部の垂直方向の移動を困難する恐れがあった。この結果、地震後に津波や洪水などが発生した際に、従来のものでは避難所と成す役目を果せなくなる恐れがあった。   However, Japanese Patent Application Laid-Open No. 2006-216991 and Japanese Patent No. 3023991 serve to serve as a refuge when a tsunami or flood occurs, gradually rising as the flood water level rises. There was a great risk of being swallowed by high waves before the building was levitated. Furthermore, the tsunami evacuation building is not currently provided with any countermeasure against earthquakes. For this reason, when an earthquake occurs and the tsunami evacuation building is damaged, the anchor pole to be expanded or contracted may not be extended smoothly, or the H-shaped steel guide column is inclined and the vertical direction of the water resistant basement There was a risk of difficult to move. As a result, when a tsunami or flood occurred after the earthquake, there was a risk that the conventional one could not serve as a shelter.

本発明は平常時に建造物を地上から5m前後の高さに保持しておくことにより、展望台,公園,テニス場などの施設、或いは建物等として使用することができ、且つ、建造物下方のスペースを市場や駐車場として有効利用ができ、更に、津波や洪水などの発生時には避難場所として利用出来る高さ可変な津波対応建造物を提供することを目的とする。   The present invention can be used as a facility such as an observatory, a park, a tennis court, or a building by keeping the building at a height of about 5 m from the ground in normal times, and at the bottom of the building. The purpose of the present invention is to provide a tsunami-ready building with a variable height that can be used effectively as a market or parking lot, and that can be used as an evacuation site in the event of a tsunami or flood.

本発明は上記現状に鑑み成されたものであり、つまり、立設する支柱と、該支柱に沿って上下移動可能な建造物と、その建造物と支柱との間で且つ建造物側に取付けた免震装置と、建造物が上下移動するための上下移動手段と、から少なくとも構成する。また1本の支柱を建造物の中央に貫通して立設させ、上下移動可能な建造物と支柱との間に免震装置を取付けるものとしても良く、又、支柱に沿って滑動する滑動体を有した滑動部材が、免震装置を介して取付けられ、前記上下移動手段として、支柱の上部と建造物の間に配置した吊下用のワイヤーロープと、該ワイヤーロープを巻回すると共に建造物側に取付けた巻取り機と、支柱の内部を上下移動可能なバランスウエイトと、から少なくとも成されたものとするのが好ましい。尚、本発明で言う「建造物」とは、建物,デッキ,橋などを指すものとする。   The present invention has been made in view of the above-described situation, that is, a column to be erected, a building that can be moved up and down along the column, and the building and the column attached to the building side. And a vertical movement means for moving the building up and down. Also, it is possible to install a seismic isolation device between the strut and a structure that can be moved up and down by penetrating one strut through the center of the building, and a sliding body that slides along the strut. A sliding member having a seismic isolation device is attached via a seismic isolation device, and as the vertical movement means, a suspension wire rope disposed between the upper part of the column and the building, and the wire rope is wound and constructed. It is preferable that at least a winder mounted on the object side and a balance weight capable of moving up and down in the column are formed. In the present invention, “building” refers to a building, a deck, a bridge, and the like.

請求項1のように立設する支柱(1)と、該支柱(1)に沿って上下移動可能な建造物(2)と、その建造物(2)と支柱(1)との間で且つ建造物(2)側に取付けた免震装置(3)と、建造物(2)が上下移動するための上下移動手段(5)と、から少なくとも構成することにより、平常時、避難デッキである建造物(2)を地上から5m前後の高さに保持しておけば、展望台,公園,テニス場などの施設として使用することができ、且つ、建造物(2)の下方のスペースは市場や駐車場などとして有効利用ができるものとなる。更に、津波や洪水などの発生時には避難場所として利用出来る。しかも、平常時の建造物(2)は、支柱(1)との間に免震装置(3)が取付けられているため、大きな地震が発生しても、従来の如き支柱(1)が傾き、或いは従来の如き建造物(2)が損傷して上昇することができなくなる恐れが殆どなくなり、地震によるダメージが殆どなく、適宜高さまで建造物(2)を上昇させて安全な避難場所が確保出来るものとなる。この時、建造物(2)が建物の場合には、大きな地震が発生しても、揺れが免震装置(3)によって緩和されて小さくなるため、地震による建造物(2)のダメージが殆どなく、安心して住むことが出来るものとなる。   A strut (1) erected as in claim 1, a building (2) vertically movable along the strut (1), and between the building (2) and the strut (1) The seismic isolation device (3) attached to the building (2) side and the vertical movement means (5) for moving the building (2) up and down at least constitutes an evacuation deck at normal times. If the building (2) is held at a height of about 5m above the ground, it can be used as a facility for observation decks, parks, tennis courts, etc., and the space below the building (2) is the market It can be used effectively as a parking lot. Furthermore, it can be used as an evacuation site in the event of a tsunami or flood. Moreover, since the seismic isolation device (3) is attached between the building (2) and the column (1) in a normal state, the conventional column (1) is tilted even if a large earthquake occurs. Or, there is almost no risk that the conventional building (2) will not be able to rise due to damage, there will be almost no damage due to the earthquake, and the building (2) will be raised to an appropriate height to ensure a safe evacuation site It will be possible. At this time, when the building (2) is a building, even if a large earthquake occurs, the vibration is alleviated and reduced by the seismic isolation device (3). There will be no need to live in peace.

請求項2のように支柱(1)を1本とし、建造物(2)の中央に貫通穴(22)を穿設させ、該貫通穴(22)に支柱(1)を貫通し、免震装置(3)を、支柱(1)と貫通穴(22)との間で且つ建造物(2)側に取付けることにより、支柱(1)は1本だけとなるため、津波や洪水等による漂流物が引掛かりにくくなり、且つ、上下移動手段(5)などの設備費が多く掛からなくなるため、安価に製作することが可能となる。   As in claim 2, there is one support column (1), a through hole (22) is drilled in the center of the building (2), the support column (1) is passed through the through hole (22), and seismic isolation is performed. By installing the device (3) between the support column (1) and the through hole (22) and on the building (2) side, there is only one support column (1), so drifting due to tsunami, flooding, etc. Since it is difficult for objects to be caught and the equipment cost for the vertical movement means (5) is not increased, it can be manufactured at low cost.

請求項3に示すよう支柱(1)に沿って滑動する滑動体(41)を有した滑動部材(4)が、免震装置(3)を介して取付けられることにより、建造物(2)の上昇がスムーズに行えるものとなる。又、大きな地震が発生しても、従来の避難所と異なり、本発明は確実に適宜高さまで建造物(2)を上昇出来るものとなる。   A sliding member (4) having a sliding body (41) that slides along a column (1) as shown in claim 3 is attached via a seismic isolation device (3), so that the building (2) Ascending can be done smoothly. Moreover, even if a big earthquake occurs, unlike the conventional refuge, this invention can raise a building (2) reliably to a height appropriately.

請求項4に示すように上下移動手段(5)として、支柱(1)の上部と建造物(2)の間に配置した吊下用のワイヤーロープ(51)と、該ワイヤーロープ(51)の一端を取付けると共に建造物(2)側に取付けた巻取り機(52)と、支柱(1)の内部を上下移動可能なバランスウエイト(53)と、から少なくとも成すことにより、建造物(2)が安定してスムーズに上下移動出来るものとなる。又、上下移動可能なバランスウエイト(53)を設けることにより、大きな重量の建造物(2)を吊上げる際、巻取り機(52)の動力装置が小さなものでも使用出来るものとなる。またワイヤーロープ(51)で重い建造物(2)を吊上げることにより、免震効果も得られるものとなる。   As shown in claim 4, as the vertically moving means (5), a wire rope (51) for suspension arranged between the upper part of the support column (1) and the building (2), and the wire rope (51) Building (2) by at least comprising a winder (52) attached at one end and attached to the building (2) side, and a balance weight (53) capable of moving up and down in the column (1) Can move up and down stably and smoothly. Also, by providing a balance weight (53) that can move up and down, when lifting a heavy building (2), even a small power unit of the winder (52) can be used. Moreover, a seismic isolation effect can be obtained by lifting a heavy building (2) with a wire rope (51).

A steel frame that enables a large span as shown in FIGS. 1 and 6 is provided at the lower part of the building (2). It has a truss structure (21). In addition, for example, in the case of FIG. 2, the width of the building (2) is preferably 40 m or more and 20 m or more. When the tsunami hits, the floating material that has flowed is caught on the column (1). It is preferable to go through without going through. The size of the building (2) is determined by the purpose of use in normal times.

(3)は建造物(2)と支柱(1)との間で且つ建造物(2)側に取付けた免震装置であり、該免震装置(3)としては、図3に示すような形状の制振ダンパーを用いるのが好ましい。又、前記免震装置(3)は建造物(2)の各隅へ図4に示すように縦横に取付けておく。更に前記免震装置(3)は図6に示すように建造物(2)の各隅に一対で取付けておくと、安定性と走行性の点で良好となる。この制振ダンパーである免震装置(3)としては、ゴム板積層材,ゴムブロック材(ムク材),油圧ダンパー,バネ材等を用いるのが良い。   (3) is a seismic isolation device attached between the building (2) and the column (1) and on the side of the building (2). The seismic isolation device (3) is as shown in FIG. It is preferable to use a damping damper having a shape. Moreover, the said seismic isolation apparatus (3) is attached to each corner of a building (2) vertically and horizontally as shown in FIG. Furthermore, if the seismic isolation device (3) is attached in pairs to each corner of the building (2) as shown in FIG. 6, the stability and running properties are improved. As the seismic isolation device (3), which is a vibration damper, it is preferable to use a rubber plate laminated material, a rubber block material (muku material), a hydraulic damper, a spring material or the like.

(4)は各免震装置(3)を介して取付けられた支柱(1)に沿って滑動する滑動体(41)を有する滑動部材であり、該滑動部材(4)としては、回転自在な滑動体(41)と、該滑動体(41)を軸支すると共に免震装置(3)に固着した軸受(42)と、支柱(1)に沿ってその支柱(1)に取付けた軌道(43)とから成されている(図3〜図6参照)。前記軌道(43)は滑動体(41)の案内の役目を果たす。   (4) is a sliding member having a sliding body (41) that slides along a column (1) attached via each seismic isolation device (3). The sliding member (4) is rotatable. A sliding body (41), a bearing (42) that pivotally supports the sliding body (41) and is fixed to the seismic isolation device (3), and a track (1) that is attached to the strut (1) along the strut (1) 43) (see FIGS. 3 to 6). The track (43) serves to guide the sliding body (41).

(5)は建造物(2)が上下移動するための上下移動手段であり、該上下移動手段(5)としては、支柱(1)の上部と建造物(2)の間に配置した吊下用のワイヤーロープ(51)と、該ワイヤーロープ(51)を巻回すると共に建造物(2)側に取付けた巻取り機(52)と、支柱(1)の内部を上下移動可能なバランスウエイト(53)と、該バランスウエイト(53)に一端を取付けると共に他端を建造物(2)側に取付けた接続用のワイヤーロープ(54)と、支柱(1)の上部に設置した2個の滑車(55)と、建造物(2)側に取付けた2個の案内車(56)と、建造物(2)側に取付けた非常用電源(57)と、から成されている。前記上下移動手段(5)は各支柱(1)に備えられている。前記ワイヤーロープ(51),(54)としては、耐腐食性で剛性を有すると共に建造物(2)の重量に充分余裕のある強度を有したワイヤーロープを用いる。尚、前記巻取り機(52)や非常用電源(57)を取付ける場合、建造物(2)側以外に支柱(1)の上部に取付けるものとしても良い。又、前記上下移動手段(5)は上記の構造に限定されるものではない。   (5) is a vertical movement means for moving the building (2) up and down, and the vertical movement means (5) is a suspension arranged between the upper part of the column (1) and the building (2). Wire rope (51), a winder (52) wound around the wire rope (51) and mounted on the building (2) side, and a balance weight capable of moving up and down in the column (1) (53), a wire rope (54) for connection with one end attached to the balance weight (53) and the other end attached to the building (2) side, and two pieces installed on the upper part of the column (1) A pulley (55), two guide wheels (56) attached to the building (2) side, and an emergency power source (57) attached to the building (2) side are included. The said vertical movement means (5) is provided in each support | pillar (1). As the wire ropes (51) and (54), wire ropes having corrosion resistance and rigidity and having a strength sufficient for the weight of the building (2) are used. In addition, when attaching the winder (52) and the emergency power supply (57), it may be attached to the upper part of the support column (1) other than the building (2) side. The vertical movement means (5) is not limited to the above structure.

(6)は建造物(2)の周囲に設けたフェンスであり、(7)は支柱(1)に取付けた階段である。この階段(7)は支柱(1)の上部に達するまでの段数が予め備えられている。   (6) is a fence provided around the building (2), and (7) is a staircase attached to the column (1). This staircase (7) is provided in advance with the number of steps until it reaches the upper part of the column (1).

図8は本実施形態の建造物(2)が建物である場合を示し、この建物としては学校,病院,住宅などの集合住宅等である。この時の支柱(1)の間隔は建物の幅に対応させる。例えば、図9に示すように前記実施形態の支柱(1)の間隔と比べると、かなり狭くなる。この支柱(1)の縦方向の間隔は、建物の部屋の幅(奥行き)にベランダと廊下を加えた幅が確保されたものとする。また前記支柱(1)の高さとしては、20m前後とするのが良い。又、免震装置(3)は、支柱(1)と建造物(2)の柱或いは梁などとの間で且つ建造物(2)側に取付けられている。尚、前記支柱(1)の高さを30m前後にすると、建築物(8)の重心が高くなって不安定になり易くなる。この場合には、支柱(1)の太さを異様に太くしなければならず、見た目が悪くなると共にコストが掛かるものになる恐れがある。   FIG. 8 shows a case where the building (2) of this embodiment is a building, which is a housing complex such as a school, a hospital, or a house. The interval between the columns (1) at this time corresponds to the width of the building. For example, as shown in FIG. 9, it is considerably narrower than the interval between the columns (1) of the above embodiment. It is assumed that the vertical distance between the columns (1) is a width obtained by adding a veranda and a hallway to the width (depth) of the room of the building. The height of the column (1) is preferably about 20 m. The seismic isolation device (3) is attached between the column (1) and the column or beam of the building (2) and on the building (2) side. In addition, if the height of the said support | pillar (1) shall be about 30 m, the gravity center of a building (8) will become high and will become unstable easily. In this case, the thickness of the support column (1) must be made unusually thick, which may make the appearance worse and increase the cost.

図10は本実施形態の支柱(1)が2本使用される場合の建造物(2)を示し、これは図1、図2の実施形態と比べ、支柱(1)が図中に於ける縦方向に長く、免震装置(3)は建造物(2)の中央両側に取付けられている。他の部材は略同じである。   FIG. 10 shows a building (2) when two columns (1) of this embodiment are used. This is because the column (1) is shown in the drawing as compared with the embodiment of FIGS. Long in the vertical direction, the seismic isolation device (3) is attached to both sides of the center of the building (2). Other members are substantially the same.

図11、図12は本発明の別実施形態を示す図であり、これは支柱(1)が1本だけの場合を示す。又、この構造は、図1、図2の実施形態と比べ、1本の支柱(1)は太く、建造物(2)の中央には、支柱(1)を貫通する貫通穴(22)が穿設されている。そして免震装置(3)は、支柱(1)と貫通穴(22)側の建造物(2)の柱或いは梁などとの間で且つ建造物(2)側に取付けられている。滑動部材(4)の個数は、支柱(1)の各隅部に取付けるため、前記実施形態と同数とする。また上下移動手段(5)は、支柱(1)の上部と建造物(2)の間に配置した2本の吊下用のワイヤーロープ(51)と、該ワイヤーロープ(51)を巻回すると共に支柱(1)の上部に取付けた巻取り機(52)と、支柱(1)の内部を上下移動可能なバランスウエイト(53)と、該バランスウエイト(53)に一端を取付けると共に他端を建造物(2)側に取付けた接続用のワイヤーロープ(54)と、支柱(1)の上部に設置した滑車(55)と、支柱(1)の上部に取付けた複数個の案内車(56)と、から少なくとも成されている。他の部材は略同じである。   FIG. 11 and FIG. 12 are diagrams showing another embodiment of the present invention, which shows a case where there is only one strut (1). In addition, this structure is thicker in comparison with the embodiment of FIGS. 1 and 2, and a through hole (22) penetrating the support column (1) is formed in the center of the building (2). It has been drilled. The seismic isolation device (3) is attached to the building (2) side between the column (1) and the pillar or beam of the building (2) on the through hole (22) side. Since the number of sliding members (4) is attached to each corner of the support column (1), the number is the same as in the above embodiment. The up-and-down moving means (5) winds two wire ropes (51) and two wire ropes (51) arranged between the upper part of the support column (1) and the building (2). A winder (52) attached to the upper part of the column (1), a balance weight (53) capable of moving up and down in the column (1), and one end attached to the balance weight (53) and the other end A wire rope (54) for connection attached to the building (2) side, a pulley (55) installed on the top of the column (1), and a plurality of guide cars (56) mounted on the top of the column (1) ) And at least. Other members are substantially the same.

次に本発明の使用方法について説明する。先ず始めに、津波発令が出た時は、上下移動手段(5)を作動させる。つまり、巻取り機(52)の図示しないスイッチを入れると、ワイヤーロープ(51)が巻取られながら建造物(2)が上昇し始めると共に、該建造物(2)の上昇に伴ってバランスウエイト(53)が降下し始める。そして、建造物(2)が支柱(1)の上部に来て自動的に止まる(図6参照)。この時、バランスウエイト(53)は降下して地上に接触或いは地上付近に来て止まる。この建造物(2)は図7(a)から図7(b)のように10m〜20m近く上昇し、避難場所として確保されるのである。この時、建造物(2)の上或いは内部に居ない人は、図7や図2などに示す階段(7)を使って建造物(2)まで登れば良い。尚、前記建造物(2)の上昇は、津波発令による津波の予想高さに対応すれば良い。例えば、津波の予想高さの2倍程度に建造物(2)を上昇させ、建造物(2)から津波の襲来状態を見て、危険を感じた時は更に建造物(2)を上昇すれば良い。   Next, a method of using the present invention will be described. First, when a tsunami is issued, the vertical movement means (5) is operated. That is, when the unillustrated switch of the winder (52) is turned on, the building (2) starts to rise while the wire rope (51) is wound, and the balance weight is increased as the building (2) rises. (53) begins to descend. And a building (2) comes to the upper part of a support | pillar (1), and stops automatically (refer FIG. 6). At this time, the balance weight (53) descends and comes into contact with the ground or stops near the ground. This building (2) rises from 10m to 20m as shown in FIG. 7 (a) to FIG. 7 (b), and is secured as an evacuation site. At this time, a person who is not on or inside the building (2) may climb the building (2) using the stairs (7) shown in FIG. The rise of the building (2) may correspond to the expected height of the tsunami due to the tsunami announcement. For example, raise the building (2) to about twice the expected height of the tsunami, watch the tsunami strike from the building (2), and if you feel danger, raise the building (2) further It ’s fine.

津波の襲来時には、建造物(2)の上或いは内部で津波が去るまでそこで待てば良い。津波が去った後、巻取り機(52)の前記スイッチを再度入れると、ワイヤーロープ(51)を戻しながら建造物(2)が降下される。すると、建造物(2)の降下に伴ってバランスウエイト(53)は上昇し始める。そして、建造物(2)の高さ、例えば5m付近になると停止させるのである。この時、バランスウエイト(53)も元の位置まで上昇して止まる。尚、前記建造物(2)が自動的に停止するのは、支柱(1)側に設けた図示しないセンサーが設けられており、このセンサーにより、巻取り機(52)が停止されるのである。また前記建造物(2)の停止操作は図示しない手動スイッチで行っても良い。前記建造物(2)が5m付近で停止すると、その下方のスペースは、図1に示すように車を止めることが出来る。このため、建造物(2)の下方の場所の利用方法としては、駐車場,朝市,夕市,常設の市場などとして平常時に有効利用すれば良い。一方、図8に示すように建造物(2)を建物とした場合には、平常時に建造物(2)を吊下状態にせず、地上に接地させたものとしても良い。   When a tsunami strikes, you can wait there until the tsunami leaves on or inside the building (2). When the switch of the winder (52) is turned on again after the tsunami leaves, the building (2) is lowered while returning the wire rope (51). Then, as the building (2) descends, the balance weight (53) starts to rise. And if it becomes the height of a building (2), for example, 5 m vicinity, it will stop. At this time, the balance weight (53) also rises to the original position and stops. The building (2) automatically stops because a sensor (not shown) provided on the support (1) side is provided, and the winder (52) is stopped by this sensor. . Moreover, you may perform stop operation of the said building (2) with the manual switch which is not shown in figure. When the building (2) stops near 5 m, the space below it can stop the car as shown in FIG. For this reason, as a method of using the place below the building (2), it may be effectively used in normal times as a parking lot, a morning market, an evening market, a permanent market, or the like. On the other hand, as shown in FIG. 8, when the building (2) is a building, the building (2) may be grounded without being suspended in a normal state.

また建造物(2)が避難デッキの場合には、建造物(2)自体の利用方法としては、展望台,公園,テニス場,フットサル場,ゲートボール場,プールなどの施設として使用することがでる。更に建造物(2)全体を温泉施設や図7に示すキャンプ場などの施設として使用すると良い。   When the building (2) is an evacuation deck, the building (2) itself can be used as a facility such as an observation deck, park, tennis ground, futsal ground, gateball field, and pool. . Furthermore, the entire building (2) may be used as a hot spring facility or a facility such as a campsite shown in FIG.

このように本発明の建造物(2)が避難デッキの場合、建造物(2)は平常時に地域住民のための種々な施設として有効利用することが出来るものとなるのである。尚、従来の如き、想定する津波の最大高さを例えば30mとして、デッキ高さを30mに設置したものとすることになれば、平常時は何ら利用価値がなく、ただ目障りなものとなってしまうが、平常時に本発明の建造物(2)を低い位置に吊下した状態とすることにより、建造物(2)自体が有効に利用できると共にその下方のスペースも有効利用できるものとなる。   Thus, when the building (2) of the present invention is an evacuation deck, the building (2) can be effectively used as various facilities for local residents in normal times. If the maximum height of the assumed tsunami is 30 m, for example, and the deck height is set to 30 m as in the past, there will be no utility value during normal times, and it will be just annoying. However, when the building (2) of the present invention is suspended at a low position in normal times, the building (2) itself can be used effectively and the space below it can be used effectively.

次に本発明の建造物(2)を建物とした場合の使用方法を図8に基づいて説明する。先ず始めに、津波発令が出た時は、建造物(2)を上昇させる。この建造物(2)を上昇させる方法は、上記の建造物(2)の上昇方法と同じ要領で行えば良い。又、建造物(2)である建物が支柱(1)の上部に来て自動的に止まった時に、建造物(2)の中に居た人は、階段(7)を使って屋上に行けば良い。一方、建造物(2)の中に居ない人は、階段(7)を使って地上から建造物(2)まで登れば良い。この建造物(2)は10m近く上昇し、避難場所として確保されるのである。尚、この建造物(2)の高さを30m近く上昇出来るものとしても良い。   Next, a method of using the building (2) of the present invention as a building will be described with reference to FIG. First, when a tsunami is issued, the building (2) is raised. The method for raising the building (2) may be performed in the same manner as the method for raising the building (2). Also, when the building (2) comes to the top of the column (1) and stops automatically, the person in the building (2) can go up the roof using the stairs (7). It ’s fine. On the other hand, the person who is not in the building (2) may climb the building (2) from the ground using the stairs (7). This building (2) rises nearly 10m and is secured as an evacuation site. In addition, it is good also as what can raise the height of this building (2) nearly 30m.

次に地震が発生した場合について説明する。先ず始めに上下の揺れを生じた時は、先ず上下波動は支柱(1)に伝わる。そして、その波動力は免震装置(3)に伝わり、上下方向に於いて図5(b)のように免震装置(3)がずれることにより、波動力を吸収して衰退させる。又、この建造物(2)はバランスウエイト(53)によって安定させようとする力が働くことにより、支柱(1)からの上下波動は、極めて小さくなった状態で建造物(2)に伝わるものとなるのである。   Next, a case where an earthquake occurs will be described. First, when an up-and-down swing is generated, the up-and-down wave is first transmitted to the support column (1). Then, the wave power is transmitted to the seismic isolation device (3), and the seismic isolation device (3) is displaced in the vertical direction as shown in FIG. In addition, the building (2) is subjected to a force to be stabilized by the balance weight (53), so that the vertical wave from the column (1) is transmitted to the building (2) in a very small state. It becomes.

次に左右の揺れを生じた時は、上記同様に先ず支柱(1)に左右波動が伝わると、その波動力は免震装置(3)に伝わり、左右方向に於いて図5(b)のように免震装置(3)が変形、つまり、ずれるか或いは伸縮することにより、波動力を四方から吸収して衰退させる。このため、支柱(1)からの左右波動は、極めて小さくなった状態で建造物(2)に伝わるものとなるのである。この時、支柱(1)は図2に示すように建造物(2)を介して免震装置(3)が取付けられることにより、4本の支柱(1)は建造物(2)で略固定された状態の如くなるため、各支柱(1)は傾き或いは折損がしにくくなると共に耐震性が向上されるものとなる。   Next, when a left / right swing occurs, as in the above case, when a left / right wave is first transmitted to the support column (1), the wave power is transmitted to the seismic isolation device (3), and in the left / right direction, as shown in FIG. Thus, the seismic isolation device (3) deforms, that is, shifts or expands and contracts, so that the wave power is absorbed from all sides and declined. For this reason, the left-right wave from the column (1) is transmitted to the building (2) in a very small state. At this time, as shown in FIG. 2, the column (1) is substantially fixed by the building (2) by attaching the seismic isolation device (3) via the building (2). Since it becomes like the state which was made, each support | pillar (1) becomes difficult to incline or break, and an earthquake resistance is improved.

このように建造物(2)が免震構造となることにより、平常時に於いて、特に図8に示すような学校,病院,住宅などの集合住宅等として利用している場合、建造物(2)自体の耐震性が得られるため、安心出来る建物となるのである。尚、本発明の建造物(2)は多種類の施設や建物を常時利用する際、定期的に建造物(2)を上下に移動させ、メンテナンスに努めるのが好ましい。   Since the building (2) has a seismic isolation structure as described above, the building (2) is usually used as a housing complex such as a school, a hospital, or a house as shown in FIG. ) Because it has its own earthquake resistance, it is a safe building. In addition, when the building (2) of the present invention always uses various types of facilities and buildings, it is preferable to periodically move the building (2) up and down to make maintenance efforts.
