図5ないし図8は、図1ないし図4に示す歩道設置型の防災シェルターの他の実施形態を示すもので、図5は上空からみた設置の様子を示す上面図、図6は図5の左上側の1つを取り出して示す拡大上面図、図7は図6を車道側からみた正面図、図8は図7の左側面図である。  FIGS. 5 to 8 show other embodiments of the disaster prevention shelter of the sidewalk installation type shown in FIGS. 1 to 4. FIG. 5 is a top view showing a state of installation viewed from above, and FIG. FIG. 7 is a front view of FIG. 6 viewed from the roadway side, and FIG. 8 is a left side view of FIG.
図5の上側と下側には、車道400およびその両側の歩道401,401を挟んでビルなどの建造物402…が建ち並んでいて、地震が発生すればこれらの建造物402からガラスやブロック片などの破壊片が次々に落下してくるような場合を想定してそれに対応するように防災シェルター403を設置したものである。これらの図に示すシェルター403はバス停の役目も兼ねているが、バス停を兼ねていない場合もある。  On the upper side and the lower side of FIG. 5, buildings 402 such as buildings are lined up between the roadway 400 and the sidewalks 401, 401 on both sides thereof. If an earthquake occurs, glass or block pieces are taken from these buildings 402. The disaster prevention shelter 403 is installed so as to cope with the case where broken pieces such as the above fall one after another. The shelter 403 shown in these figures also serves as a bus stop, but may not also serve as a bus stop.
歩道401には、複数本の支柱405…が8点配置をもって垂直に立設されている。それら支柱405…の上端間は上連結材406によりつながれているとともに、上連結材406や支柱405で囲まれた立面の特に建造物402…側の面には、窓枠407が取付けられるとともに各窓枠407にはポリカーボネートなどの強度のある防護板408が採光可能なものとして嵌め込まれている。  On the sidewalk 401, a plurality of support columns 405 are vertically arranged with eight points. The upper ends of the columns 405... Are connected by the upper connecting member 406, and a window frame 407 is attached to the surface of the upright surface surrounded by the upper connecting member 406 and the column 405, particularly on the building 402. A strong protective plate 408 such as polycarbonate is fitted into each window frame 407 so that it can be lit.
この防災シェルター403の中には、バスを待つ人や休みたい人などが座ることのできる椅子409…がビル側(車道側でもよい)に配備されており、この椅子409は、前記のように蓋を開閉可能にして椅子下ケース内に収納しておいた非常用品類を使用できるようにしてもよい。  In this disaster prevention shelter 403, a chair 409... That can be used by a person waiting for a bus or a person who wants to take a rest is arranged on the building side (may be on the roadway side). You may make it possible to use the emergency supplies stored in the chair lower case by opening and closing the lid.
天井構造は、前記上連結材406の上面を介してルーフ410が図8のように設けられているとともに、同ルーフ410上には、パネル枠411と緑地枠412が受皿状をなして取付けられている。パネル枠411は、車道400側の半分を占め、緑地枠412は建造物402側の半分を占める。緑地枠412内には、自然物である草木が天井緑地413として設けられる。  In the ceiling structure, a roof 410 is provided as shown in FIG. 8 through the upper surface of the upper connecting member 406, and a panel frame 411 and a green frame frame 412 are attached in a tray shape on the roof 410. ing.

In the green space frame 412, a natural plant is provided as a ceiling green space 413.
パネル枠411内には、ソーラーパネル414…が多数枚配備されている。緑地枠412とパネル枠411の境目には給水管415が設けられ、歩道のところまで延びていることにより、給水管415に明けた霧ノズルから定期的に噴霧が可能になっている。この噴霧はソーラーパネル414の向きに対してもパネル清掃の目的で行うように構成することもできる。  A large number of solar panels 414 are arranged in the panel frame 411. A water supply pipe 415 is provided at the boundary between the green frame 412 and the panel frame 411 and extends to the side of the sidewalk so that spraying can be periodically performed from the fog nozzle opened in the water supply pipe 415. This spraying can also be performed for the purpose of panel cleaning with respect to the orientation of the solar panel 414.
ビルからの落下物は屋根部分の特にビル側において広がって設けられた天井緑地413により受け止められ、その際、緑地413であるので好適な緩衝作用をもって落下物を受け止めることができる。また、平常時には、緑地413は夏季の暑さをしのぐなど環境保全に適しさらにビル上からみても好ましい景観を提供する。ソーラーパネル414は破壊されやすいが、同パネル414は車道401側に配置しているので落下物に当たりにくい。  Falling objects from the building are received by the ceiling green space 413 provided to spread on the roof side, particularly on the building side. At this time, since the green space 413, the falling objects can be received with a suitable buffering action. Further, during normal times, the green space 413 is suitable for environmental conservation such as surpassing the heat of summer and provides a favorable landscape from the viewpoint of the building. Although the solar panel 414 is easily destroyed, the panel 414 is disposed on the side of the roadway 401 so that it is difficult to hit a fallen object.
尚、図6および図7に示すように、シェルター403の外部に相当する路面には、衝撃吸収質路材417を配備しておけば落下物418…が路面に落ちたあと割れてシェルター403内や他の路面上の人に損傷を与えるおそれが少ない。
また、図5に示すように、シェルター403間には網状材などによる防護連結材420を渡架しておけばシェルター403間を歩く人にも安全を与えることができる。この防護連結材420にも独自の支柱などの支持構造を構成することができる。
As shown in FIGS. 6 and 7, if a shock-absorbing road material 417 is provided on the road surface corresponding to the outside of the shelter 403, the fallen object 418... And less likely to damage people on other road surfaces.
In addition, as shown in FIG. 5, if a protective connecting member 420 made of a net-like material is bridged between the shelters 403, safety can be given to people walking between the shelters 403. The protective connecting member 420 can also have a support structure such as a unique support column.
図9および図10は他の実施形態を示すもので、緑地422の占有面積を広くとるようにしたもので、図9の実施形態は、ソーラーパネル423を屋根面積のうち車道424側でかつ片隅にあるようにしたもので、図10の実施形態は、ソーラーパネル423を車道424側に直線状に細長く設けて緑地422の面積を極力広くしかも落下物に対し有効に機能するようにしたものである。
尚、図9および図10の下欄に示すものはパネル防護網425で、パネル423上に離間して張設される。
9 and 10 show another embodiment, in which the occupied area of the green space 422 is increased. In the embodiment of FIG. 9, the solar panel 423 is arranged on one side of the roadway 424 in the roof area. In the embodiment shown in FIG. 10, the solar panel 423 is elongated in a straight line on the side of the roadway 424 so that the area of the green space 422 is as large as possible and functions effectively against falling objects. is there.
Note that what is shown in the lower column of FIGS. 9 and 10 is a panel protection net 425 that is spaced apart from the panel 423.

尚、250は避難用シェルターで、スチールパイプなどを部屋型に組み合わせてなり、その中にベッド251を装備しておくことにより家屋が倒壊しても就寝している人が護られるようになっている。この場合のシェルター250は、床下まで床下コラム251を延ばして倒壊時に床抜けしないようにしてある。
このシェルター250に天連結材252を介して前記補強フレーム240を連結してある。このように補強フレーム240とシェルター250とを相互連結しておくことで、家屋の揺れ自体も抑制されるとともにシェルター250の安定性も向上するごとくお互いが協働し合う。
また、図14に仮想線で示す補強フレーム240からは垂直柱253を垂下して床下まで埋め込み固定するようにしてもよい。この場合、図14の右側の横架部242は省略することもできる。
Reference numeral 249 denotes a second-floor connecting member that extends from the horizontal portion 242 to the second-floor housing and is connected to prevent the second-floor housing from shaking.
In addition, 250 is an evacuation shelter, which is a combination of steel pipes, etc., and is equipped with a bed 251 to protect people who are sleeping even if the house collapses. Yes. The shelter 250 in this case extends the underfloor column 251 to the underfloor so that it does not fall out when collapsed.
The reinforcing frame 240 is connected to the shelter 250 via a top connecting member 252. By interconnecting the reinforcing frame 240 and the shelter 250 in this way, the house itself can be prevented from shaking, and the stability of the shelter 250 can be improved.
Further, the vertical pillar 253 may be suspended from the reinforcing frame 240 shown by phantom lines in FIG. In this case, the right horizontal portion 242 in FIG. 14 may be omitted.
図16は補強フレーム255を外基礎256から立ち上げた外支柱257内に差し込んで支持効果を向上させるようにしたものである。この場合、右欄に示すように外基礎256はブロック258にモルタル259を打設した基礎構造であってもよい。
尚、前記実施形態では、横架部233,242は金属パイプ状のものとされていたが、図16に上側に示すようにワイヤ・ロープ・リンクチェーンなどの線条材260であってもよい。この場合、この線条材260は、例えば、床梁226などの躯体側に止め付けたり巻き付けたりして家屋の揺れや倒壊を阻止するようにしてもよい。
また、図16の右下欄に示すように、横架材を線条材260とするとともに同材260の両端を斜め引っ張り材(ワイヤ・ロープ・リンクチェーンなど)261,261に一体接続して家屋の揺れや倒壊を阻止するようにしてもよい。
さらに、前記支柱部232,241はゴム質でもよいし、横架部226もゴム質でもよい。
In FIG. 16, the reinforcing frame 255 is inserted into the outer support column 257 raised from the outer foundation 256 to improve the support effect. In this case, as shown in the right column, the outer foundation 256 may be a foundation structure in which a mortar 259 is placed on the block 258.
In addition, in the said embodiment, although the horizontal parts 233 and 242 were made into the shape of a metal pipe, as shown to the upper side in FIG. 16, it may be a linear material 260, such as a wire, a rope, and a link chain. . In this case, for example, the wire material 260 may be stopped or wound around a frame such as the floor beam 226 to prevent the house from shaking or collapsing.
In addition, as shown in the lower right column of FIG. 16, the horizontal member is a wire member 260, and both ends of the member 260 are integrally connected to diagonal pull members (wires, ropes, link chains, etc.) 261, 261. You may make it prevent a house from shaking or collapsing.
Further, the support portions 232 and 241 may be made of rubber, and the horizontal portion 226 may be made of rubber.
