Description

この発明は、とくに海岸に比較的近くで丘陵地などの高台のない地域にあるガソリンスタンドなどの給油所跡地を津波避難施設となる構造に改築する改築方法及び該改築方法によって構築された津波避難施設に関する。   The present invention relates to a remodeling method for remodeling a gas station or other gas station in a region that is relatively close to the coast and without a hilly area, such as a hilly area, into a structure serving as a tsunami refuge facility, and a tsunami evacuation constructed by the remodeling method Regarding facilities.
東北地方太平洋沖地震に伴う大津波のように海側に面した海岸線の地域には、近々の大地震の発生とそれに伴う大津波の到来が統計学的に予測されている。居住地や職場、学校、更には通学、通勤経路の近くにこのような予測される津波にも十分に避難対応できる丘陵地や公共の建造物がある場合はともかくも、多くの人の場合には、こうした滞在時間の長い常時居る所に津波避難施設がないのが実情である。そこで、津波が到来した場合の緊急避難場所としての人工の津波避難施設がこれまでに提案されている(例えば、特開2006−83549号)。   In the coastal area facing the sea side like the Great Tsunami associated with the Tohoku Pacific Ocean Earthquake, the occurrence of a major earthquake in the near future and the arrival of a major tsunami are statistically predicted. In the case of many people, whether there are hilly areas or public buildings near the place of residence, workplace, school, or even commuting to work or commuting routes that can sufficiently respond to such a predicted tsunami The fact is that there is no tsunami evacuation facility in such a long-time stay. Thus, an artificial tsunami evacuation facility as an emergency evacuation site when a tsunami arrives has been proposed so far (for example, JP-A-2006-83549).
一方、近年の消防法改正による燃料保管タンクの規制強化に伴う設備維持経費の増大に加えて、若者の自動車離れや電気自動車の台頭等の理由によりガソリンの需要が減り、廃業するガソリンスタンドが年々増加している現状がある。ガソリンスタンドは、一旦廃業するとその設備の性質上再開は困難であるので、完全に解体するか、そのまま残した建物だけを別の用途として利用するしか方法がない。   On the other hand, in addition to the increase in equipment maintenance costs accompanying the recent tightening of fuel storage tank regulations due to the revision of the Fire Service Law, the demand for gasoline has decreased due to reasons such as the departure of young people from automobiles and the rise of electric cars. There is an increasing current situation. Once a gas station is closed, it is difficult to resume due to the nature of its facilities, so there is no other way but to dismantle it completely or use only the building that is left as it is for another purpose.
特開2006−83549JP 2006-83549 A
しかしながら、前記の人工の津波避難施設は、新たに設置する場合には目立ちやすく人通りが比較的多い場所に用地を確保しなければならないので、用地探しが困難であると共に用地買収や施設構築の予算の確保上の問題点がある。更に、完成した避難施設が街の風景に溶け込まないことが多く、街の景観上の問題点がある。又、避難施設の構築に代えて既存の建築物を利用することも考えられるが、津波避難施設の高さは、津波想定高さの1.5倍以上としなければならないので、想定高さが3mを超える場合には既存の建築物を利用することができない場合が多く、結果として、新築の施設を構築せざるを得ない問題点がある。   However, the above-mentioned artificial tsunami evacuation facility, when newly installed, has to secure a site in a conspicuous and relatively crowded place, so it is difficult to find a site, and land acquisition and facility construction There is a problem in securing the budget. In addition, the completed evacuation facilities often do not blend into the cityscape, which causes problems in the cityscape. It is also possible to use existing buildings instead of building evacuation facilities, but the height of the tsunami evacuation facility must be at least 1.5 times the expected height of the tsunami. When it exceeds 3 m, there are many cases in which existing buildings cannot be used, and as a result, there is a problem that a new facility must be constructed.
一方、前述の理由により年々その数を増す廃業されるガソリンスタンドの一般的な構造は、地下には燃料保管タンクを抱え、地上には事務室、整備室、サービスルームなどに利用している建築物があり、更には、給油機器や給油作業者から雨や直射日光を避けるために支柱によって支えられた屋根を有するキャノピィー部があるので、他の利用用途の施設に変更するのが難しく、又、解体工事をして更地にするにしても地下の燃料保管タンクから地上のキャノピー部の屋根の解体工事などその跡地の整備には多額の経費を要するという問題点がある。
この発明はこのような事情に鑑みて、双方の抱える課題を同時に解決することを目的としてなされたものである。
On the other hand, the general structure of a gas station that is going out of business for the reasons described above has a fuel storage tank in the basement and is used for offices, maintenance rooms, service rooms, etc. on the ground. In addition, since there is a canopy part with a roof supported by props to avoid rain and direct sunlight from refueling equipment and refueling workers, it is difficult to change to a facility for other uses, However, even if the site is demolished, there is a problem that a large amount of expenses are required for the construction of the site, such as the construction of the ground canopy roof from the underground fuel storage tank.

この発明の給油所跡地を利用した津波避難施設への改築方法及び津波避難施設によれば、年々その数を増す給油所跡地の有効利用が図られ、且つ、津波の避難所を安価に構築できる。ガソリンスタンドなどの給油所は元々自動車や人通りが多くて道路沿いに設置されているので、そこに給油所の高く掲げられた看板を避難所の看板に代えておけば、良く目立って地域住民等に周知・啓発や避難時の混乱を防止できるし、急に津波警報が出されて逃げ遅れた場合でも逃げ込み易い。とくに、その跡地内の建築物を託児所やデイケアなどの弱者の施設に改築した場合には退避誘導も楽であり退避遅れを防止出来る。又、このような日常的に利用できる施設に改築することで、津波避難施設の管理や運用の役割も同時に行える。更に、改築のためのコストも安価である。   According to the rebuilding method and the tsunami evacuation facility using the gas station site of this invention and the tsunami evacuation facility, the number of gas station sites that increase year by year can be effectively used, and a tsunami shelter can be constructed at low cost. . Gas stations such as gas stations were originally built along the road with lots of cars and traffic, so if you replace the high signboard of the gas station there with a signboard for the evacuation shelter, the local residents will stand out well. It is easy to get away even if the tsunami warning is suddenly issued and delayed. In particular, when the building in the site is remodeled into a facility for the weak, such as daycare or day care, evacuation guidance is easy and delays in evacuation can be prevented. In addition, by remodeling the facilities that can be used on a daily basis, the tsunami evacuation facility can be managed and operated at the same time. Furthermore, the cost for renovation is low.
そして、給油所自体が、その設置時に街の景観に合致するように構築されているので、改造を加えても基本的な構成は変わらないことから街の景観を損ねることはない。更に、給油所は海岸に沿った津波浸水警戒領内に多いことからその跡地利用は特に有効であるのに加え、多くの場合に構築の施主となる行政庁としてみれば新たな津波避難所を構築する場合のように用地確保の心配もない。更にピロティー部の支柱は、車の出入りを効率よく行うように丈夫で本数を少なくして屋根を支えているので、津波の波力や漂流物を避けられ易く好都合である。更に、屋根は平屋根又は勾配の小さい屋根が殆どなので、屋根面をそのまま避難者の避難床面としたり改良を加える場合でも改築工数が少なくて済む。 And since the gas station itself is constructed to match the cityscape at the time of installation, the basic structure will not change even if remodeling is made, so the cityscape will not be damaged. Furthermore, since there are many gas stations in the tsunami inundation warning area along the coast, the use of the ruins is particularly effective. You don't have to worry about securing land like you do. Furthermore, since the pillars of the piloty part are strong so as to efficiently enter and exit the vehicle and support the roof by reducing the number of cars, it is easy to avoid the tsunami wave force and drifting objects. Further, since the roof is mostly a flat roof or a roof with a small slope, even if the roof surface is used as an evacuation floor surface of the evacuees as they are or improvements are made, the number of renovation steps can be reduced.
支柱に波力や漂流物が当たった場合にも、又、屋根に大勢の人が避難してもそれらの荷重に耐えられるように補強されているので安全である。又、屋根面を避難床面としその周囲の一部若しくは全部に手摺を設けたので、避難床面から落下する危険性が無い。   Even if wave power or drifting object hits the column, it is safe because the roof is reinforced to withstand those loads even if a large number of people evacuate. Moreover, since the roof surface is used as the evacuation floor surface and the handrail is provided on a part or all of the periphery thereof, there is no risk of falling from the evacuation floor surface.
更に又、避難床面への避難手段を設けたので、これを利用して地上から十分に高い位置にあるピロチィー部の屋根に相当する避難床面に避難出来る。 Furthermore, since an evacuation means for the evacuation floor surface is provided, it is possible to evacuate to the evacuation floor surface corresponding to the roof of the piloty part at a sufficiently high position from the ground.
避難手段が給油地跡地の地面と避難床面とを連絡する階段であれば、給油所跡地にいる人は容易に避難できる。又、この階段を方向を変えて複数個設置しておけば、津波と到来方向と逆の位置にある階段を利用できる安全である。 If the evacuation means is a stairway that connects the ground of the refueling site and the evacuation floor, a person at the refueling site can easily evacuate. Also, if a plurality of staircases are installed in different directions, it is safe to use the staircase at a position opposite to the arrival direction of the tsunami.
避難手段が給油所跡地の建築物と退避床面とを連絡する渡り通路である場合には、建築物の階段等から上階へ移動し、そこから渡り通路を通って避難床面に行くことが出来るので、途中の階段の設置が不要であり、又、建築物から移動するので、逃げ遅れて津波が押寄せて来ても少しは安全である。更に、渡り通路を介して連絡することにより、避難床面を支柱だけで支持する場合に較べてより確固に保持できる。また、この渡り通路にも人が避難できるので、より多くの人が避難できる。 If the evacuation means is a transit passage that connects the building at the gas station site and the evacuation floor, move from the stairs of the building to the upper floor and go from there to the evacuation floor through the passage. Therefore, it is not necessary to install stairs on the way, and because it moves from the building, it is a little safe even if the tsunami comes after being delayed. Furthermore, by communicating via the crossing passage, the evacuation floor can be held more firmly than in the case where the evacuation floor is supported only by the columns. Moreover, since people can evacuate to this passage, more people can evacuate.
キャノピー部の支柱の補強を、上端が支柱の中心部と連結固定され、下端が地面に固定される下補強斜柱を用いることにより、津波の波圧、波力や漂流物から支柱を保護出来る。この下補強斜柱を支柱の回りに複数個用いた場合には、下補強斜柱を設置した数だけの津波の方向に対する補強が出来る。一つの屋根を複数の支柱で支持しているキャノピー部の場合には、それぞれの支柱について、全て同じ方向を向いた下補強斜柱を用いても良いし、あらゆる方向からの津波に対応するために各支柱毎に設置方向を変えても良い。又、支柱に対する下補強斜柱の取付角度は特に限定されるものではないが、45°が強度的に好ましい。 Reinforcement of the canopy strut can be protected from tsunami wave pressure, wave force and drifting objects by using a lower reinforcing oblique column whose upper end is connected and fixed to the center of the strut and whose lower end is fixed to the ground. . In the case where a plurality of lower reinforcing oblique columns are used around the support column, it is possible to reinforce the number of tsunami directions as many as the lower reinforcing oblique columns are installed. In the case of a canopy that supports a single roof with multiple columns, it is possible to use lower reinforcing diagonal columns that face the same direction for each column, and to respond to tsunamis from all directions. The installation direction may be changed for each column. Further, the angle at which the lower reinforcing oblique column is attached to the support column is not particularly limited, but 45 ° is preferable in terms of strength.
又、キャノピー部の支柱の補強を、下端が支柱の中心部と連結固定され、上端が屋根に連結固定された上補強斜柱を用いているので、屋根と支柱の一点の支持よりも、上補強斜柱の数だけ多くの点で屋根を支持出来、支持強度が向上し、避難床面にそれだけ多くの人が避難できる。ここで、下補強斜柱の延長方向に上補強斜柱を設けた場合には、避難床面からの荷重を支柱及び下補強斜柱を通じて地面で受け止められるので、支柱に作用する荷重は、真上からの荷重が大部分となり補強強度が向上する。 In addition, the reinforcement of the column of the canopy part uses an upper reinforcing diagonal column whose lower end is connected and fixed to the center of the column and whose upper end is connected and fixed to the roof. The roof can be supported at as many points as the number of reinforced prisms, the support strength is improved, and so many people can evacuate to the evacuation floor. Here, when the upper reinforcement oblique column is provided in the extending direction of the lower reinforcement oblique column, the load from the evacuation floor can be received by the ground through the support column and the lower reinforcement oblique column. The load from the top is large and the reinforcing strength is improved.
又、屋根の下面に新たに設けた補強梁を介して、上補強斜柱の上端と屋根とを連結固定すれば、屋根を点ではなく線で支持出来るので、ラーメン効果を得られる。この場合の補強梁は、屋根の長手方向に介在させる方がより効率的である。 Further, if the upper end of the upper reinforcing oblique column and the roof are connected and fixed via a reinforcing beam newly provided on the lower surface of the roof, the roof can be supported by a line rather than a point, so that a ramen effect can be obtained. In this case, it is more efficient to interpose the reinforcing beam in the longitudinal direction of the roof.
下補強斜柱と上補強斜柱の数は多いほど支柱を強固に且つ屋根の荷重を支えられるが、これらは支柱の周りに等間隔に設置すれば支柱に掛かる荷重を均等に分布することが出来、全体として均整がとれ耐久力が向上する。 The greater the number of lower and upper reinforced oblique columns, the stronger the columns and the load on the roof can be supported. However, if they are installed at equal intervals around the columns, the load applied to the columns may be evenly distributed. It can be balanced and improve durability as a whole.
キャノピー部の支柱の補強が、屋根の両側を両端が柱部材によって支持されている梁部材に吊られている場合には、避難床面に多数の人が載った場合でもその荷重を梁部材で受け止めることが出来るので、支柱への負担を軽減できる。柱部材によっても津波の波圧、波力や漂流物から支柱を阻止出来る。柱部材は梁部材の中央部にも設けても良い。この支柱の補強の場合には、屋根の下に補強した柱がないので、屋根下空間を日常の活動の場として有効に活用できる。なお、支柱の強度補強を更に高めたい時には、屋根下空間が犠牲になるが、前記の下補強斜柱や上補強斜柱を用いて支柱や屋根を補強しても良い。   When the canopy strut reinforcement is hung on a beam member that is supported on both sides of the roof by pillar members, the load is supported by the beam member even when a large number of people are placed on the evacuation floor. Since it can be received, the burden on the support can be reduced. The pillars can also be used to block the tsunami from wave pressure, wave power and drifting objects. The column member may also be provided at the center of the beam member. In the case of reinforcement of this column, since there is no column reinforced under the roof, the space under the roof can be effectively used as a place for daily activities. Note that, when it is desired to further strengthen the strength of the column, the space under the roof is sacrificed, but the column and the roof may be reinforced using the lower reinforcing oblique column and the upper reinforcing oblique column.
柱部材が鉄筋コンクリートであれば、津波の波力や漂流物の衝撃に対する抵抗が大きくなる利点がある、梁部材は屋根を吊った場合の荷重を支えるだけの構造であれば良いので鉄骨造で良い。この鉄骨造の構造体の内部に、飲食糧、医薬品、防寒用具、救難信号発信機等の非常用品を収納できる収納庫を確保しておけばより好都合である。   If the column member is reinforced concrete, there is an advantage that the resistance against the tsunami wave force and the impact of the drifting object is increased. The beam member may be a steel structure because it only needs to support the load when the roof is suspended. . It would be more convenient if a storage room for storing emergency supplies such as food, medicines, cold protection tools, rescue signal transmitters, etc. was secured inside the steel structure.
キャノピー部の支柱の補強が、当該支柱の周囲において下端が地面に固定された上端が屋根に連結固定された支持柱を用いれば、屋根の避難床面に避難者が多数載った場合でもその荷重を支えられる。また、支柱に津波の波圧、波力や漂流物の直接衝突による衝撃を防止できる。上端が屋根の構成材であるグリッドの直交点で連結固定すればより確実に連結出来る。   The reinforcement of the canopy support can be achieved even when a large number of evacuees are placed on the evacuation floor of the roof by using a support column with the lower end fixed to the ground around the support and the upper end connected to the roof. Can be supported. In addition, it is possible to prevent tsunami wave pressure, wave force and impact caused by direct collision of drifting objects on the support. If the upper end is connected and fixed at an orthogonal point of the grid, which is a component of the roof, it can be connected more reliably.

The gas station A is facing the roadway and has a substantially quadrangular shape that is paved as a whole, and there is a building 4 with rooms such as an office 1, a repair bit 2, and a service yard 3 at the corner. A refueling device 5 is arranged at a predetermined distance on the front side of the building 4, and a canopy unit 6 is provided for preventing the refueling device 5 and the refueling worker from rain and direct sunlight. The canopy unit 6 is composed of a plurality of columns 6 fixed to the ground in the vicinity of the refueling device 5 and a roof 7 supported by the columns 6, and the roof 7 is surrounded by three refueling devices 5. The upper part and the upper part between the oil supply apparatus 5 and the front side of the building 4 are covered. Also, a fuel storage tank 9 is buried in the basement of the site between the building 4 and the refueling device 5 at the end. Further, an advertising tower 10, a waste oil tank 11, a fire extinguisher box 12, a fire pit 13 and the like are provided.
この給油所跡地Aを、例えば図3に示す津波避難施設Bへ改築するには、既存の給油所跡地Aにある前記の諸設備の内、特に、キャノピー部6の支柱7の津波の波圧、波力や漂流物などの衝撃に対する水平荷重や多数の避難者の積載荷重に対する補強、屋根8面の避難床面14への改築、当該避難床面14の全周囲又は一部周囲への手摺15の設置、給油所跡地Aの地面から若しくは建築物4からの避難手段としての階段16若しくは渡り通路17の設置である。この内、キャノピー部6の具体的な補強の方法が3通りあり、この改築方法とその改築後の設備について図に基づいて順次他の改築をも含めて説明する。   For example, in order to rebuild this gas station A to a tsunami evacuation facility B shown in FIG. 3, for example, the tsunami wave pressure of the pillar 7 of the canopy section 6 among the above-mentioned facilities in the existing gas station A , Horizontal load against impacts such as wave force and drifting objects, reinforcement against load capacity of many evacuees, reconstruction of roof 8 to evacuation floor 14, handrail to all or part of evacuation floor 14 15, installation of stairs 16 or a passageway 17 as an evacuation means from the ground of the gas station A or from the building 4. Among these, there are three specific methods for reinforcing the canopy section 6, and the remodeling method and the equipment after the remodeling will be described sequentially with reference to the drawings, including other remodeling.
まず、キャノピー部6の具体的補強方法の第1の実施例を図〜図7に示す。この実施例では建築物4については託児所とした場合の部屋の配置を示し、例えば、補修ビット2を保育室18とこれに付随する小部屋とし、サービスヤード3を貯水タンクや蓄電池装置などの非常時用部材室19とし、事務室1をランチルーム20やプレイルームあるいはその他の事務室や職員の更衣室など種々の目的に活用する。 First, a first embodiment of a specific method for reinforcing the canopy portion 6 in FIGS. 3 to 7. In this embodiment, the layout of the building 4 is shown as a nursery. For example, the repair bit 2 is a childcare room 18 and a small room attached thereto, and the service yard 3 is a water storage tank or storage battery device. The emergency member room 19 is used, and the office room 1 is used for various purposes such as a lunch room 20, a play room, other office rooms, and staff changing rooms.
キャノピー部6の支柱7は、下補強斜柱71と上補強斜柱72を用いて補強されている。下補強斜柱71は下端を地面に固定し上端を支柱7の中央部に連結固定したものである。支柱7の垂直方向の維持と津波の波圧、波力や漂流物からの保護が目的である。支柱7に対する傾斜角度は特に限定されるものではないが、45°が最適である。地面への固定は地中でコンクリートで固めたもので良く、支柱7との連結固定はボルト・ナット、溶接、取付金具などを介して行うが、他の手段によってこれらの固定を行っても良い。取付個数は支柱7が四角柱であればその周りにそれぞれ90°の等間隔で4個が適当である。支柱7が円柱であれば取付金具を介して行うのが適しており、その個数は4個に限定されるものではない。 The support column 7 of the canopy unit 6 is reinforced by using a lower reinforcing oblique column 71 and an upper reinforcing oblique column 72. The lower reinforcing oblique column 71 has a lower end fixed to the ground and an upper end connected and fixed to the central portion of the column 7. The purpose is to maintain the column 7 in the vertical direction and to protect it from tsunami wave pressure, wave power and drifting objects. Although the inclination angle with respect to the support column 7 is not particularly limited, 45 ° is optimal. The fixing to the ground may be solidified with concrete in the ground, and the connection and fixing to the support column 7 is performed through bolts / nuts, welding, mounting brackets, etc., but these may be fixed by other means. . If the support column 7 is a quadrangular column, the number of attachments is suitably four at equal intervals of 90 °. If the support | pillar 7 is a cylinder, it is suitable to carry out via an attachment metal fitting, and the number is not limited to four pieces.
上補強斜柱72も同様にして、下端を支柱7の中央部に上端を屋根8に連結固定し、又、取付角度や個数についても同様にして、屋根8の上に設けた避難床面14に載った避難者の荷重を受けて支柱7に伝達する役目を持つ。この時、下補強斜柱71の中心線の延長上に上補強斜柱72の中心線が位置するように配置すれば、上補強斜柱72に掛かる避難者の荷重が下補強斜柱71に伝達され、支柱7の負担が更に軽減される。上補強斜柱72の上端と屋根8との連結は、屋根8に使用されている構造部材に直接連結固定しても良いが、図4、図5に示すように、屋根8の下面に補強梁21を設け、この補強梁21に上補強斜柱72の上端を連結固定すれば、屋根面すなわち避難床面14の補強を兼ね備えるものとなる。又、この補強梁21の長手方向からの津波に対してはラーメン効果をも得られる。 Similarly, the upper reinforcing oblique column 72 is connected and fixed at the lower end to the center portion of the column 7 and the upper end is connected to the roof 8, and the evacuation floor surface 14 provided on the roof 8 is similarly set with respect to the mounting angle and number. It receives the load of the refugee on the board and transmits it to the column 7. At this time, if the center line of the upper reinforcing oblique column 72 is positioned on the extension of the center line of the lower reinforcing oblique column 71, the load of the evacuees on the upper reinforcing oblique column 72 is applied to the lower reinforcing oblique column 71. As a result, the burden on the column 7 is further reduced. The connection between the upper end of the upper reinforcing oblique column 72 and the roof 8 may be directly connected and fixed to a structural member used for the roof 8, but it is reinforced on the lower surface of the roof 8 as shown in FIGS. 4 and 5. If the beam 21 is provided and the upper end of the upper reinforcing oblique column 72 is connected and fixed to the reinforcing beam 21, the roof surface, that is, the evacuation floor surface 14 is also reinforced. Further, a ramen effect can be obtained against a tsunami from the longitudinal direction of the reinforcing beam 21.
支柱7、下補強斜柱71及び上補強斜柱72は、同じ断面構造の部材を用いても異なる部材であっても良い。支柱7が四角材である時には、上下の補強斜柱72,71を支柱7の各面の上下方向中央部に連結固定して支柱7を挟んで1組がX状になるようにしたものに対して直角にもう1組を固定したものとすれば支柱7の回りに等間隔に90°となり強度的に好ましい。 The strut 7, the lower reinforcing oblique column 71, and the upper reinforcing oblique column 72 may be members having the same cross-sectional structure or different members. When the support column 7 is a square member, the upper and lower reinforcing oblique columns 72 and 71 are connected and fixed to the center in the vertical direction of each surface of the support column 7 so that one set becomes an X shape with the support column 7 interposed therebetween. On the other hand, if another set is fixed at a right angle, it is 90 ° at equal intervals around the support column 7, which is preferable in terms of strength.
避難手段としての階段16は、図3に示すように、建築物4側とその反対側の2か所に2つ設けて、万一の場合に備えておくのが望ましい。この階段16の他にも、図7に示すように、建築物4と避難床面14を連結固定する渡り通路17を設けておいても良い。この渡り通路17は、キャノピー部6を構成する屋根8を建築物4に連結固定する役目をも持つ。また、この渡り通路17が長い場合には、この路面上にも人が立つことが出来るので、避難者の数を増やすことが出来る。なお、このような構造体以外の退避手段として、退避床面14上にロープや縄梯子などを備えて、階段16や渡り通路17が破損した場合や漂流者救済用の避難手段としても良い。 As shown in FIG. 3, two staircases 16 as evacuation means are preferably provided in two places on the building 4 side and the opposite side, and are prepared in case of an emergency. In addition to the staircase 16, as shown in FIG. 7, a crossing passage 17 for connecting and fixing the building 4 and the evacuation floor 14 may be provided. The crossing passage 17 also serves to connect and fix the roof 8 constituting the canopy portion 6 to the building 4. In addition, when this transfer passage 17 is long, people can stand on this road surface, and the number of evacuees can be increased. In addition, as a evacuation means other than such a structure, a rope, a rope ladder, or the like may be provided on the evacuation floor surface 14, and the stairs 16 or the passageway 17 may be damaged or may be an evacuation means for relief of a drifter.
屋根8の上面に設ける避難床面14は、多くの場合に屋根8が平屋根或いは勾配が小さい屋根であるので特段の改築をすることなくそのままでも使用できるが、例外的に勾配が大きい場合には、避難者に不安を与えない程度の最小限の勾配となるように屋根面を水平方向に改築することが必要である。又、屋根8が平屋根の場合であっても、その重量を軽減し、多くの避難者が載った場合の重量バランスが取り易いように改築しても良い。又、避難床面14の表面には滑り止めを施しておくと安全である。更に、この避難床面14の周囲に設ける手摺15は、屋根8の構造体と連結した確固なものとしておくことが望ましい。更に、前記した避難手段としての階段16、渡り通路17、手摺15、新たに改築した避難床面14などは、パンチングメタル、ラス金網、網目、隙間のある格子状細金属線、などのように重量には耐え得るが多くの間隙を有する素材を採用すれば津波の波圧、波力を減衰させるために好適である。   The evacuation floor surface 14 provided on the upper surface of the roof 8 can be used as it is without special remodeling because the roof 8 is a flat roof or a roof with a small gradient in many cases. Therefore, it is necessary to rebuild the roof surface in the horizontal direction so as to have a minimum gradient that does not cause anxiety to the evacuees. Further, even when the roof 8 is a flat roof, the weight may be reduced, and the roof 8 may be remodeled so as to easily balance the weight when many evacuees are placed. Further, it is safe to provide a slip stopper on the surface of the evacuation floor 14. Furthermore, it is desirable that the handrail 15 provided around the evacuation floor 14 is a solid one connected to the structure of the roof 8. Further, the stairs 16, the passageway 17, the handrail 15, the newly reconstructed evacuation floor 14 as the evacuation means, such as punching metal, lath wire mesh, mesh, grid-like fine metal wire with gaps, etc. Adopting a material that can withstand the weight but has many gaps is suitable for attenuating the wave pressure and wave force of the tsunami.
給油所跡地Aには、キャノピー部6や建築物4の他にも、地下の燃料保管タンク9、広告塔10、防火塀13などの設備があり、これらも津波避難設備Bとして有効活用できる。例えば、燃料保管タンク9は、真水の保存、或いはその内部に浮体を収納して津波の水が浸入することに伴う浮体の浮力を生かして救助信号を発する装置に応用することなどに利用できる。又、広告塔10は元々隣接する道路に向けて視認できるように大きく高く掲げられているので、これに避難施設の表示をしておくことにより地域住民等への周知・啓発を日常的に行えて、避難時の混乱防止に役立てられる。防火塀13は、近隣の家屋などが火災になっても熱風や延焼を有効に防止でき、避難床面14上の避難者を守ることができる。   In addition to the canopy section 6 and the building 4, the gas station A has facilities such as an underground fuel storage tank 9, an advertising tower 10, a fire pit 13, and the like, which can also be effectively used as a tsunami evacuation facility B. For example, the fuel storage tank 9 can be used for storage of fresh water, or for application to a device that generates a rescue signal by utilizing a buoyancy of a floating body that is stored inside the floating body and tsunami water enters. In addition, since the advertising tower 10 is originally raised so as to be visible toward the adjacent road, the evacuation facility is displayed on the advertising tower 10 so that the local residents can be informed and enlightened on a daily basis. This helps to prevent confusion during evacuation. The fire pit 13 can effectively prevent hot air and fire spread even if a nearby house becomes a fire, and can protect refugees on the evacuation floor 14.
建築物4は、その使用目的を明確化することによって種々の改築が可能である。図2に示す建築物4の間取りを前述した図3に示す託児所に改築することが出来る。この場合には、貯水タンクや蓄電池盤などの非常時用資材を保管する防災用具室19も併せ持つようにしておけば尚良い。又、避難床面14の下方は、風通しの良い日陰となり、テラスとして、幼児の遊び場としても活用できる。建築物4は、老人ホーム、デイケア施設、介護施設など身体的弱者の施設とすれば、逃げ遅れた場合にも緊急避難し易い。   The building 4 can be remodeled in various ways by clarifying its purpose of use. The floor plan of the building 4 shown in FIG. 2 can be renovated to the day nursery shown in FIG. In this case, it is better to have a disaster prevention equipment room 19 for storing emergency materials such as water storage tanks and storage battery panels. In addition, the area below the evacuation floor 14 is a well-ventilated shade and can be used as a terrace or a playground for infants. If the building 4 is a facility for physically weak people such as a nursing home, a day care facility, a nursing facility, etc., it is easy to evacuate easily even if it is delayed.
キャノピー部6の具体的補強の第2の実施例は、図8、図9に示されるように、キャノピー部6を構成する屋根8を両端が柱部材22によって支持されている梁部材23に吊られている構造である。柱部材22は、鉄筋コンクリ―トのように丈夫な構造の方が津波の波圧、波力や漂流物によっても耐え得ることができ、支柱7の保護をも兼ね備えることが出来る。梁部材23は、鉄骨造で中空部24を有し、屋根8の長手方向の両側をワイヤーやボルト等の吊部材25で吊って、あるいは直接に連結固定して屋根8すなわち避難床面14上に避難者が多数載った場合でも支柱7に荷重が掛かることを防ぐ。柱部材22は梁部材23の中央部にも設けても良い。又、梁部材23についても、避難床面14の短手方向に複数設けても良い。更に、柱部材22、梁部材23を鉄骨等からなるアーチ状に形成して、ロープや鉄筋などで避難床面14を吊る構成としても良く、この場合には、周囲の景観が良くなる利点がある。退避手段としての階段16は、長手方向の端部の柱部材22の間が適しているが、その他の場所であっても良い。又、階段16の設置は、柱部材22を巻回するようにすればより強固に固定でき、津圧、波力等によっても破壊される可能性が少なくなる。   As shown in FIGS. 8 and 9, in the second embodiment of concrete reinforcement of the canopy portion 6, the roof 8 constituting the canopy portion 6 is hung on a beam member 23 supported at both ends by column members 22. It is a structure that has been. The column member 22 can withstand a tsunami wave pressure, wave force and drifting material, and can protect the column 7 with a strong structure such as a rebar concrete. The beam member 23 is made of steel and has a hollow portion 24, and both sides in the longitudinal direction of the roof 8 are suspended by suspension members 25 such as wires and bolts or directly connected and fixed to the roof 8, that is, on the evacuation floor surface 14. Even when a large number of evacuees are placed on the column 7, it is possible to prevent the column 7 from being loaded. The column member 22 may also be provided at the center of the beam member 23. Also, a plurality of beam members 23 may be provided in the short direction of the evacuation floor 14. Furthermore, the pillar member 22 and the beam member 23 may be formed in an arch shape made of a steel frame or the like, and the evacuation floor surface 14 may be hung by a rope or a reinforcing bar. In this case, there is an advantage that the surrounding landscape is improved. is there. The stairway 16 as the retracting means is suitable between the column members 22 at the end portions in the longitudinal direction, but may be other places. Further, the staircase 16 can be installed more firmly if the column member 22 is wound, and the possibility that the staircase 16 is destroyed due to tsunami, wave force, or the like is reduced.
梁部材23の中空部24は、飲食糧、医薬品、防寒用具、救難信号発信機等の非常時用資材の格納庫として用いることや、避難床面14に載った避難者の手摺代わりにもなる。更に、外方向を向いている側面には避難所の表示をすることで、広告塔10と同じ目的を持たせられる。更に、避難床面14下には柱等の支持部材が存在しないことから、広い空間を得られ、有効活用が可能となる。   The hollow portion 24 of the beam member 23 is used as a hangar for emergency materials such as food, medicines, cold protection tools, rescue signal transmitters, etc., and serves as a handrail for evacuees on the evacuation floor 14. Furthermore, the same purpose as the advertising tower 10 can be given by displaying a shelter on the side facing outward. Furthermore, since there is no support member such as a pillar under the evacuation floor 14, a large space can be obtained and effective use can be achieved.
キャノピー部6の具体的補強の改築方法及び津波避難設備Bの第3の実施例は、図10に示すように、支柱7の周囲において下端が地面に固定され上端が屋根に連結固定された複数の支持柱26によって、屋根8すなわち避難床面14を支えるようにしたものである。支持柱26の数は径の大小、素材強度などによって影響を受けるので特定されるものではないが、支柱7の周囲に設けることで、支柱7を津波の波圧、波力や漂流物から保護する役割をも有していることから、予想される津波の到来方向を考慮しながら均等に荷重を支持できる位置に配置するのが望ましい。    As shown in FIG. 10, the third embodiment of the concrete reinforcement reconstruction method of the canopy portion 6 and the tsunami evacuation equipment B includes a plurality of lower ends fixed to the ground and upper ends connected to the roof, as shown in FIG. The support pillar 26 supports the roof 8, that is, the evacuation floor 14. The number of support pillars 26 is not specified because they are affected by the size of the diameter and the strength of the material. However, the support pillars 26 are provided around the support pillars 7 to protect the support pillars 7 from tsunami wave pressure, wave power and drifting objects. Therefore, it is desirable to arrange the load at a position where the load can be evenly supported in consideration of the expected arrival direction of the tsunami.
支持柱26の屋根8との連結固定は、屋根8の構造体のグリッドの直交点で行えばより確固に固定でき安定する。この場合、既存の屋根8の梁のグリッドを分割して、例えば1.4mの直交グリッドを作り、その全ての交点27に支持柱26を配置し、避難者の載った避難床面14からの荷重を分散して受けるようにする。これにより、支持柱26の径が細くても本数が多く取れるので荷重を耐え得る。   The connecting and fixing of the support pillar 26 with the roof 8 can be more firmly fixed and stabilized if it is performed at the orthogonal point of the grid of the structure of the roof 8. In this case, the beam grid of the existing roof 8 is divided into, for example, a 1.4 m orthogonal grid, and support pillars 26 are arranged at all the intersections 27 from the evacuation floor 14 on which the refugees are placed. Distribute the load. Thereby, even if the diameter of the support pillar 26 is thin, a large number can be taken, so that the load can be endured.
前記第1乃至第3実施例の支柱7の補強を採用した場合の全体の試算について説明する。避難床面14の高さは、想定される津波の高さの1.5倍が必要であることから、キャノピー部6の避難床面14までの高さを6.0mとした場合には、想定津波高さが4.0までは耐え得るものとした。避難床面14の面積が一般的なガソリンスタンドのキャノピー部6の屋根8で約300mであるので、この面積から最大600人収容可能であると試算し、ここから全体荷重36tを算出した。支柱7は断面が正四角で幅が400mmの金属柱を用い上下補強斜柱72,71も同じとした。支柱7及び屋根8に対する連結固定角度は45°とした。下補強斜柱71の地面への固定は、下端を地中でコンクリートで覆ったものとした。階段16は、避難床面14の向い合せに2か所に設け、幼児や要介護者も利用することを考慮して高さと踏面の比を1対2とした。建築物4は託児所として利用し、図に示すように各室を配置するよう改築した。 The overall trial calculation when the reinforcement of the column 7 of the first to third embodiments is employed will be described. Since the height of the evacuation floor 14 needs to be 1.5 times the height of the assumed tsunami, when the height to the evacuation floor 14 of the canopy portion 6 is 6.0 m, The assumed tsunami height can withstand up to 4.0. Since the area of the evacuation floor 14 is about 300 m 2 on the roof 8 of the canopy section 6 of a general gas station, it was estimated that a maximum of 600 people can be accommodated from this area, and the total load 36t was calculated therefrom. The column 7 is a metal column having a regular square cross section and a width of 400 mm, and the vertical reinforcing oblique columns 72 and 71 are the same. The connection fixing angle with respect to the column 7 and the roof 8 was 45 °. The lower reinforcing oblique column 71 was fixed to the ground with the lower end covered with concrete in the ground. The stairs 16 are provided at two locations facing the evacuation floor 14 and the ratio of height to tread is set to 1: 2 in consideration of use by infants and care recipients. Building 4 was used as a day-care center, and was renovated to place each room as shown in the figure.
以上の説明からも明らかなように、この発明の給油所跡地を利用した津波避難施設への改築方法及び津波避難施設によると、廃業されて放置状態の給油所の跡地を津波の避難施設として改築することが出来る。   As is clear from the above explanation, according to the method of remodeling a tsunami evacuation facility using the gas station site of the present invention and the tsunami evacuation facility, the site of the gas station that has been abandoned and left untreated is converted into a tsunami evacuation facility. I can do it.
この発明は、廃業したガソリンスタンドなどの給油所跡地を津波避難設備として有効活用できるので、各自治体等における公共施設への設備投資を図り、給油所跡地の所有者にはその資産売却益あるいは施設や土地の賃貸料収入が得られる。   This invention enables effective use of a gas station, such as a gas station, that has been closed down as a tsunami evacuation facility, so that the capital investment in public facilities in each local government, etc. And land rental income.
