Description

この発明は、津波が発生した時に住民が避難するためにしようする津波避難用タワーに関するものである。  The present invention relates to a tsunami evacuation tower that is used by residents to evacuate when a tsunami occurs.

平成２３年３月１１日に発生した東日本大震災と、それに伴って発生した大津波により亡くなった死者と行方不明者の合計は２万人以上にも及び、今後も、東海トラフ地震等の大地震や大津波が発生するおそれのあることが指摘されており、災害時に自ら救命するための対策を準備しておくことが不可欠になっている。  The total of the dead and missing people who died due to the Great East Japan Earthquake that occurred on March 11, 2011 and the accompanying great tsunami reached more than 20,000 people. Large earthquakes such as the Tokai Trough Earthquake will continue in the future. It has been pointed out that there is a risk of a large tsunami, and it is indispensable to prepare measures for saving lives in the event of a disaster.

大地震が発生した際、津波災害に遭遇しないためには、いち早く安全な高台等に避難することが必要であるが、震源地が近い時や、高台の無い沿岸部で生活している人にとっては高いビルや高台等へ避難する時間的余裕がなく、特に、高齢者など足腰が弱い人の場合には、大地震発生から大津波が到達するまでの短時間の間に、ビル等の長い階段を上って高い位置にある屋上へと避難するのは非常に大変なことであり、また、車で避難する場合には交通渋滞等により避難場所までの移動が困難な状況となり、避難途中に津波に巻き込まれて死亡する危険性が高かった。  In order to avoid encountering a tsunami disaster when a major earthquake occurs, it is necessary to evacuate to a safe high ground as soon as possible, but for people living near the epicenter or on coastal areas where there is no high ground There is no time to evacuate to high buildings, high grounds, etc., especially in the case of elderly people such as those with weak legs. It is very difficult to evacuate up to the high rooftop by going up the stairs, and when evacuating by car, it becomes difficult to move to the evacuation site due to traffic congestion etc. There was a high risk of death from being caught in a tsunami.

さらに、昨年８月に示された南海トラフ巨大地震の被害想定では、死者は最大３２万人、建物全壊は２３８万棟と見込まれたことから、鉄骨構造で十数メートルの高さのタワー型避難台の建築も提案されている。しかし高齢者などが短時間の内に十数メートルの高さの階段を登ることが出来るかどうか疑問も残ると共に、津波の高さが十数メートル以内であるかどうかの保証も無いため、普及する段階まで至っていない。  Furthermore, in the Nankai Trough earthquake forecast shown last August, the death toll was estimated to be up to 320,000 people and the total destruction of the building was expected to be 2.38 million. A shelter building has also been proposed. However, there are still doubts about whether elderly people can climb stairs that are more than 10 meters high in a short time, and there is no guarantee that the height of the tsunami is within 10 meters or less. The stage has not been reached.

このような実情に鑑みて、地盤上に複数本の支柱と横枠とからなる構造体を構築し、その構造体に、予想津波高さ以上の床面を構築した高架式金属建造物が、例えば特許文献１で提案されているが、予想津波高さ超えた大津波が押し寄せてきた場合の対策としては不十分であった。  In view of such circumstances, an elevated metal structure in which a structure composed of a plurality of columns and horizontal frames is constructed on the ground, and a floor surface that is higher than the expected tsunami height is constructed in the structure, For example, although proposed in Patent Document 1, it is insufficient as a countermeasure when a large tsunami exceeding the expected tsunami height has come.

さらに、地中固定された支柱に連結した油圧シリンダーの駆動により避難タワーを昇降させる技術が、例えば特許文献２で提案されているが、昇降可能の高さを超えた大津波が押し寄せてきた場合の対策としては不十分であった。  Furthermore, although the technique which raises / lowers an evacuation tower by the drive of the hydraulic cylinder connected to the support | pillar fixed in the ground is proposed by patent document 2, for example, when the big tsunami exceeding the height which can be raised / lowered has approached It was insufficient as a countermeasure.

以下、この発明の実施の形態１について説明する。
［発明の実施の形態１］Embodiment 1 of the present invention will be described below.
Embodiment 1 of the Invention

図１乃至図６には、この発明の実施の形態１を示す。  1 to 6 show a first embodiment of the present invention.

図１は、本発明の津波避難タワー浮上式シェルターを示す。津波避難タワー浮上式シェルターはタワー部２０と浮上式シェルター１７で構成し、タワー部２０は４本の角型鋼材で構成した支柱７と、支柱７の上部に浮上式シェルター１７を載せるため、四辺をＨ型鋼材で構成したＨ形鋼枠２１と、浮上式シェルター１７の出入口ドア１４に出入りすることが出来るように途中に踊り場１１を設けた階段１０で構成し、タワー部２０の上に載せる浮上式シェルター１７の後方部１６の後方鋼板１５は、中央上部を、概ね六角の形状をした厚さ１ｍｍのステンレス鋼板で、横約２．４ｍ、高さ約２．４ｍの大きさに成形され、中央部には上下２個の丁番２２で出入口ドア１４を取付けられる。上部の六角の一辺の大きさは、最上部の中央部左右が約４０ｃｍ、それに続く左右の辺が約６７ｃｍ、さらに、それに続く左右の辺が約６７ｃｍ、さらに、それに続く垂直の側面は高さ約１ｍの大きさで成形される。  FIG. 1 shows a tsunami evacuation tower floating shelter according to the present invention. The tsunami evacuation tower levitation shelter is composed of a tower section 20 and a levitation shelter 17, and the tower section 20 has four columns 7 made of square steel and the levitation shelter 17 placed on the top of the column 7. Is composed of an H-shaped steel frame 21 made of H-shaped steel and a staircase 10 provided with a landing 11 on the way so that it can enter and exit the entrance door 14 of the floating shelter 17 and is placed on the tower portion 20. The rear steel plate 15 of the rear portion 16 of the floating shelter 17 is a 1 mm thick stainless steel plate having a generally hexagonal shape at the center upper portion, and is formed to a size of about 2.4 m in width and about 2.4 m in height. In the center, the entrance door 14 can be attached by two upper and lower hinges 22. The size of one side of the upper hexagon is about 40cm on the left and right sides of the center of the uppermost part, about 67cm on the left and right sides, and about 67cm on the left and right sides. Molded with a size of about 1 m.

前方部２の前方鋼板５は、後方部１６の後部鋼板１５と同様に、中央上部を、概ね六角の形状をした厚さ１ｍｍのステンレス鋼板で、横約２．４ｍ、高さ約２．４ｍの大きさに成形され、中央部には開閉窓１８を取付ける。上部の六角の一辺の大きさは、中央部左右が約４０ｃｍ、それに続く左右の辺が約６７ｃｍ、さらに、それに続く左右の辺が約６７ｃｍ、さらに、それに続く垂直の側面は高さ約１ｍの大きさで成形される。  The front steel plate 5 of the front part 2 is a stainless steel plate having a thickness of approximately 1 mm and a substantially hexagonal shape at the center upper portion, similar to the rear steel plate 15 of the rear part 16, about 2.4 m wide and about 2.4 m high. The opening / closing window 18 is attached to the central portion. The size of one side of the upper hexagon is about 40 cm on the left and right sides of the central part, about 67 cm on the left and right sides, and about 67 cm on the left and right sides. Molded in size.

このように成形した後方鋼板１５と前方鋼板５を両端に取付け、浮上式シェルター１７の上部と側面を構築するため、後方鋼板１５と前方鋼板５の、六角の形状と一致するように、頂上部に対して左右を同一形状で別々に厚さ１ｍｍ、長さ約３．６ｍのステンレス鋼板を折り曲げて天井部鋼板３（辺が約４０ｃｍ）、中間部鋼板４（辺が約６７ｃｍ）、下部鋼板５（辺が約６７ｃｍ）、側面鋼板１９（縦が約１ｍ）を形成し、天井部鋼板３の端部（長さ約３．６ｍ）を頂上部で結合すると共に、天井部鋼板３と中間部鋼板４と下部鋼板５と側面鋼板１９の端部を後方鋼板１５と前方鋼板５に取付けることにより、浮上式シェルター１７が構築される。このように上部を多角形状に構成することにより、浮上式シェルター１７の強度が増すと共に、浮上式シェルター１７が横転した場合においても、直ちに元の状態に復帰することが可能となった。  The rear steel plate 15 and the front steel plate 5 thus formed are attached to both ends and the top and side surfaces of the rear steel plate 15 and the front steel plate 5 are matched with the hexagonal shape in order to construct the upper part and the side surface of the floating shelter 17. The stainless steel plate with the same shape on the left and right sides, separately with a thickness of 1 mm and a length of about 3.6 m, is bent, and the ceiling steel plate 3 (side is about 40 cm), the middle plate steel plate 4 (side is about 67 cm), and the lower steel plate 5 (side is about 67 cm), a side steel plate 19 (length is about 1 m) is formed, and an end (length: about 3.6 m) of the ceiling steel plate 3 is joined at the top, and the ceiling steel plate 3 and the middle The floating shelter 17 is constructed by attaching the end portions of the partial steel plate 4, the lower steel plate 5 and the side steel plate 19 to the rear steel plate 15 and the front steel plate 5. By configuring the upper part in a polygonal shape in this way, the strength of the floating shelter 17 is increased, and even when the floating shelter 17 rolls over, it can immediately return to its original state.

さらに、タワー２０の上部のＨ形鋼枠２１の四隅の角部には、浮上式シェルター１７が地震等で揺れ落ちないように８枚の板状の止板２７が浮上式シェルター１７の下部側面に当接して取付けられると共に、平時に浮上式シェルター１７をタワー２０に固定しておくため、脱着アンカー（イ）に示したように、浮力室８の側面下部にＬ形軸受け金具２５を取付けると共に、浮上式シェルター１７の床面に軸受け金具２４を取付け、このように取付けられたＬ形軸受け金具２５と軸受け金具２４の穴（図示せず）に、コの字形をして先端部２６が斜めに折り曲げられた脱着アンカー２３を差し込み、脱着アンカー２３を回転させて先端部２６でＨ形鋼枠２１のフランジを挟むことにより、浮上式シェルター１７とＨ形鋼枠２１が一体となり、台風等の強い風の場合でも、浮上式シェルター１７がタワー２０から落ちることが無くなった。また、大津波で浮上式シェルター１７に避難した場合には、脱着アンカー（ロ）に示したように、脱着アンカー２３を回し、脱着アンカー２３の先端部２６とＨ形鋼枠２１との結合を解除することにより、大津波が押し寄せてきた際には、浮上式シェルター１７がタワー２０から浮かび上がり無事に避難することが可能となった。このように構成した脱着アンカーを、前方部２と後方部１６の２箇所に取付けることにより浮上式シェルター１７が地震等で揺れた場合においても、浮上式シェルター１７がタワー２０から落ちることが無くなった。  Further, eight plate-like stop plates 27 are provided at the corners of the four corners of the H-shaped steel frame 21 at the top of the tower 20 so that the floating shelter 17 does not shake down due to an earthquake or the like. In order to fix the floating shelter 17 to the tower 20 during normal times, an L-shaped metal fitting 25 is attached to the lower part of the side surface of the buoyancy chamber 8 as shown in FIG. The bearing bracket 24 is attached to the floor surface of the floating shelter 17, and the L-shaped bearing bracket 25 and the hole (not shown) of the bearing bracket 24 are attached in this manner, and the tip portion 26 is slanted. The demountable anchor 23 bent in the direction is inserted, the demountable anchor 23 is rotated, and the flange of the H-shaped steel frame 21 is sandwiched by the tip portion 26, whereby the floating shelter 17 and the H-shaped steel frame 21 are integrated. Even in the case of strong winds, etc., floating-type shelter 17 is no longer possible to fall from the tower 20. Further, when evacuated to the floating shelter 17 due to a large tsunami, as shown in the desorption anchor (b), the desorption anchor 23 is turned so that the tip 26 of the desorption anchor 23 and the H-shaped steel frame 21 are coupled. By releasing, when a large tsunami comes, the floating shelter 17 emerges from the tower 20 and can be evacuated safely. By attaching the detachable anchors configured in this manner to the front part 2 and the rear part 16, the floating shelter 17 does not fall from the tower 20 even when the floating shelter 17 is shaken by an earthquake or the like. .

図２は、浮上式シェルター１７の下部に取付けられる浮力室８を部品図で示す。浮力室８は、ステンレス鋼板で、厚さ１ｍｍ、高さ約３０ｃｍ、横約３．６ｍ、縦約２．４ｍの枡形に成形した底部鋼板４０と、木材で構築した木枠フレーム３１と、発泡スチロール３０で形成された浮力材で構成され、底部鋼板４０の内側に、底部鋼板４０の前部鋼板４１、後部鋼板４４、横鋼板４２、４５の内部寸法と同一大きさで成形した、外枠が、前部枠木材３２と、後部枠木材３５と、横枠木材３３と、横枠木材３９で構成され、内部には木枠フレーム３１を補強するため、縦方向と横方向に、それぞれ縦梁木材３６、３７、３８と、横梁鋼材３４が取付けられる。発泡スチロール３０は木枠フレーム３１の枠と梁と間に挟まれた空間に合わせて立方体に成形され、浮上式フレーム１７を浮かせるため浮力体としての役目を果たすように構成される。  FIG. 2 is a component diagram showing the buoyancy chamber 8 attached to the lower part of the floating shelter 17. The buoyancy chamber 8 is a stainless steel plate, a bottom steel plate 40 formed into a bowl shape having a thickness of 1 mm, a height of about 30 cm, a width of about 3.6 m, and a length of about 2.4 m, a wooden frame 31 made of wood, and polystyrene foam. The outer frame is formed of the buoyancy material formed at 30 and is formed on the inner side of the bottom steel plate 40 with the same size as the front steel plate 41, the rear steel plate 44, and the horizontal steel plates 42, 45 of the bottom steel plate 40. The front frame lumber 32, the rear frame lumber 35, the horizontal frame lumber 33, and the horizontal frame lumber 39 are provided. Wood 36, 37, 38 and cross beam steel 34 are attached. The expanded polystyrene 30 is formed into a cube in accordance with the space sandwiched between the frame and beam of the wooden frame 31, and is configured to serve as a buoyancy body for floating the floating frame 17.

図３は、図２で説明した底部鋼板４０の内部に木枠フレーム３１を収納し、前部鋼板４１、後部鋼板４４、横鋼板４２、４５に空けた穴４６にビス４７を差し込み、木枠フレーム３１を底部鋼板４０に固定すると共に、木枠フレーム３１の枠と梁で囲まれた空間に発砲スチロール３０を嵌め込み、木枠フレーム３１の上部に合板で床を施工することにより浮力室８を構築し、浮力室８の上部に浮上式シェルター１７を取付けた津波避難タワー浮上式シェルターが、大津波が押し寄せて水位が上がったことにより浮上式シェルター１７がタワー部から離れ水面５０上に浮かび上がった状態を示す。  3 stores the wooden frame 31 inside the bottom steel plate 40 described with reference to FIG. 2, and screws 47 are inserted into holes 46 formed in the front steel plate 41, the rear steel plate 44, and the horizontal steel plates 42 and 45. While fixing the frame 31 to the bottom steel plate 40, the foamed polystyrene 30 is fitted in the space surrounded by the frame and beam of the wooden frame 31, and the buoyancy chamber 8 is formed by constructing a floor with plywood on the upper part of the wooden frame 31. The tsunami evacuation tower levitation shelter, constructed and mounted with the levitation shelter 17 at the top of the buoyancy chamber 8, floats away from the tower and rises on the water surface 50 when the water level rises due to a large tsunami. Indicates the state.
