  In the present embodiment, all of the slope 4, the stairs 17, the evacuation ladder 18, and the simple lift 19 constitute an elevating unit for evacuees.

  As shown in FIG. 3, in the rescue / evacuation fence of the present embodiment, it is possible to construct the radio tower 6 by using the center column 11.

  That is, as shown by the broken line in FIG. 3, when the radio tower 6 is constructed above the rescue / evacuation fence of this embodiment, the radio tower 61 is extended upward at the upper end of the center post 11. To fix. Further, if necessary, the reinforcing tower 62 connects the tower 61 for the radio tower and the appropriate slope inner column 12. Thus, the tower 61 for the radio tower is erected on the rescue / evacuation fence, and the post 61 is configured as a part of the radio tower 6.

  Here, the radio tower 6 is a facility for transmitting and receiving radio waves for communication and broadcasting.

  In this embodiment, the radio tower 6 may be constructed in parallel with the construction of the rescue / evacuation fence, or after the construction of the rescue / evacuation fence, if necessary, the radio tower 6 may be installed later. You may make it build. However, in the present invention, the radio tower 6 is not necessarily provided, and the radio tower 6 may not be provided.

  Further, in the rescue / evacuation cage of the present embodiment, it is possible to build a heliport on which the helicopter can take off and landing on the top floor stage 32 or the like. By installing a heliport in this way, it is possible to quickly rescue a disaster victim or dispatch a rescue team to a disaster area using a helicopter as will be described later.

  As shown in FIGS. 1 and 4, an openable / closable door 20 is provided at the entrance / exit portion on the ground floor of the rescue / evacuation cage of the present embodiment. The door 20 can be configured to be lockable, for example, as a security measure. When the lockable door 20 is employed, it can be unlocked in an emergency, for example, in conjunction with J-ALERT (National Instantaneous Warning System) or manually.

  A solar panel as a solar power generation system or a stationary storage battery such as a stationary lithium ion storage battery can be installed in the rescue / evacuation cage of this embodiment.

  Moreover, you may make it install a stationary TV monitor, a speaker, etc. in the evacuation stage 31 and top floor stage 32 of the rescue / evacuation cage of this embodiment as needed.

  The evacuation stage 31 may be stocked with water supply facilities (water supply facilities), simple water tanks, public telephones, communication devices, generators, floats, portable televisions, radios, life jackets, and the like. Furthermore, a simple toilet or the like may be installed.

  According to the rescue / evacuation cage of the present embodiment configured as described above, since the slope outer column 13 having high rigidity of the S structure is arranged outside the slope 4 arranged spirally on the outer periphery, The strength against the collision of the drifting object drifting by the tsunami can be improved, and the damage or breakage of the slope 4 can be effectively prevented.

  In addition, in the present embodiment, the slope 4 itself is constituted by a highly rigid material in which reinforced concrete is laminated on the deck plate, and the slope inner column 12 inside thereof is also constituted by a highly rigid material. As described above, the structural material such as the slope 4 and the columns 12 and 13 having high rigidity surrounds the outer periphery of the eaves, so that it is possible to further increase the strength against the collision of unspecified drifting objects caused by the tsunami.

  Further, in the present embodiment, since the vertical members 15 are attached at predetermined intervals in the circumferential direction between the slope outer columns 13, relatively small unspecified drift objects such as driftwood have been washed away. However, it can be received by the vertical member 15, and it is possible to effectively prevent the drifting object from entering the rescue / evacuation cage.

  Moreover, in this embodiment, since the center support | pillar 11 is installed in the center of a rescue and refuge fence, and the radio tower 6 can be built using the center support | pillar 11, it is possible to install the radio tower 6. There is no need to secure a separate installation space, and accordingly, the installation space can be used effectively and space saving can be achieved.

  Furthermore, in the rescue / evacuation cage with the radio tower in which the radio tower 6 is installed in the rescue / evacuation cage of the present embodiment, the rescue / evacuation cage and the radio tower 6 can be supported by the columns 11 to 13 respectively. That is, since the support column for supporting the rescue / evacuation fence and the support column for supporting the radio tower 6 can be used together, the number of support columns can be omitted as much as it can be used. Similarly, a part of the foundation of the rescue / evacuation fence can be used as a part of the foundation of the radio tower 6. For this reason, the rescue / evacuation fence with a radio tower according to the present embodiment omits a part of the foundation and the structural material compared to the case where the radio tower and the rescue / evacuation fence are individually constructed individually. be able to. Therefore, it is possible to reduce the burden of construction while ensuring a predetermined strength, and it is possible to reduce the cost.

  In particular, in the rescue / evacuation cage with a radio tower according to the present embodiment, the radio tower 6 can be arranged at the center of the rescue / evacuation cage in plan view. It can be supported in a well-balanced manner, and the radio tower 6 can be supported in a more stable state.

  Further, in the rescue / evacuation cage of this embodiment, the strength of the rescue / evacuation cage itself can be further increased because it is supported by the central column 11 arranged at the center position in addition to the surrounding columns 12 and 13. In addition, the strength against earthquakes and tsunamis can be further increased.

  Further, in the rescue / evacuation cage of this embodiment, since the central column 11 is installed at the center position, the length dimension of the horizontal beam 21 disposed inside the slope inner column 12 can be shortened.

  That is, when a horizontal beam is bridged between any slope inner column 12 and the other slope inner column 12 on the opposite side through the center of the ridge, if any center column does not exist, either It is necessary to directly connect between the slope inner column 12 and the other slope inner column 12 by a horizontal beam, and a long beam with a long span is required. For this reason, materials such as horizontal beams have become heavier and larger in size, and it becomes difficult to carry materials into the field and handle them. Therefore, the construction work of the rescue / evacuation fence itself becomes difficult, which may cause the construction period to be prolonged and the cost to increase.

  Therefore, in the rescue / evacuation cage of this embodiment, since the central column 11 is arranged at the center position, a horizontal beam is laid from any one of the slope inner columns 12 to the other slope inner columns 12. When passing, the horizontal beam 21 is bridged between any of the slope inner column 12 and the central column 11, and the horizontal beam 21 is bridged between the central column 11 and the other ramp inner column 12, Any one of the slope inner struts 12 and the other slope inner struts 12 can be connected by two horizontal beams 21 and 21 having short dimensions. For this reason, it is possible to reduce the size and weight of materials such as horizontal beams, to easily carry in and handle materials on site, and to facilitate construction of rescue and evacuation cages. The construction period can be shortened and the cost can be reduced.

  Further, in the present embodiment, the slope outer inclined beam 43 spanned between the adjacent slope outer columns 13 is inclined according to the inclination of the slope 4, and the slope 4 is supported by the slope outer inclined beam 43. ing. For this reason, the slope outer inclined beam 43 can be used as a connecting member that connects the adjacent slope outer columns 13 and a support member that supports the slope 4. Therefore, the number of parts to be assembled can be reduced, the construction period can be shortened more reliably, and the cost can be reduced.

  Further, the rescue / evacuation cage of the present embodiment has one corner portion (for example, the lower left corner portion in FIGS. 4 to 7) facing the coast in plan view. In other words, when a tsunami occurs, one corner portion of the rescue / evacuation trap is disposed opposite to the direction of the push wave (the direction indicated by the arrow D1 in FIG. 5), and the one corner of the rescue / evacuation cage is described above. The other corner portion (for example, the upper right corner portion in FIGS. 4 to 7) disposed diagonally with the portion is disposed to face the traveling direction of the pulling wave (the direction indicated by the arrow D2 in FIG. 5). ing. For this reason, it is possible to catch drifting objects caused by pushing waves and pulling waves at the time of tsunami occurrence at the corner without receiving it at the outer wall (side surface) of the rescue / evacuation fence, and to further secure the strength against the tsunami. it can.

  In the present embodiment, as shown by a broken line in FIG. 5, a brace material 26 is attached between the central column 11 and the slope inner column 12 at the lower left corner, and the slope inner column 12 at the central column 11 and the upper right corner. The brace material 26 may be attached between the two. By attaching the brace material 26 along the diagonal line of the rescue / evacuation fence along the traveling direction of the tsunami as described above, the strength against the tsunami can be further improved.

  In addition, the rescue / evacuation cage of this embodiment has a simple lift 19 that can be moved up and down between the ground and the evacuation stage 31, so that people who have difficulty in evacuation, such as movement restriction persons, can use the simple lift 19. It can be easily guided from the ground to the evacuation stage 31.

  In addition, since the simple lift 19 is arrange | positioned inside the slope inner side support | pillar 12, the simple lift 19 can be reliably supported by this support | pillar 12 in the state which does not have trouble in strength.

  Furthermore, since the pedestrian slope 4 is installed in a spiral shape on the outer periphery of the rescue / evacuation cage, those who have difficulty in evacuation using wheelchairs can be surely guided from the ground onto the evacuation stage 31 with the slope 4. can do.

  Further, an evacuation stairs 17 and an evacuation ladder 18 are installed as lifting means other than the pedestrian slope 4 and the simple lift 19. Since a large number of lifting means can be secured for evacuees in this way, a number of evacuees can be efficiently and efficiently used in a short time by using these lifting means 4, 17, 18, and 19 as appropriate. It can be guided to the top floor stage 32.

  In addition, in the rescue / evacuation cage of this embodiment, helicopters can evacuate the evacuees, and carry in and out luggage such as blankets and clothing necessary for the evacuees, food / rescue / evacuation cages of this embodiment. .
