Description

  The present invention relates to a tsunami evacuation tower used by residents to evacuate when a tsunami occurs.

  If a tsunami exceeding 1m in height is expected due to an earthquake, the Japan Meteorological Agency will issue a tsunami warning approximately three minutes after the earthquake. However, in the 1993 Hokkaido Nansei-oki Earthquake, residents were not able to evacuate on Okushiri Island, which was close to the epicenter, and in early areas, a tsunami hit only a few minutes after the earthquake and many lives were lost.

  At least after the tsunami warning is issued, it is necessary to evacuate immediately to a height higher than the expected tsunami height, but because the evacuation site is far from the residential area, the evacuation cannot be completed by the arrival of the tsunami There is no end to it. In addition, especially for elderly people and persons with physical disabilities, it is often difficult to evacuate to high ground as soon as possible, and in some cases, it is impossible to move by oneself. In the near future, the occurrence of large earthquakes and the resulting tsunamis are feared, especially in areas where there is a risk of tsunami strikes.

As conventional tsunami evacuation measures, for example, Patent Document 1 discloses a technique for a tsunami evacuation tower. This tsunami evacuation tower is constructed by constructing a structure composed of a plurality of support columns and a horizontal frame on the ground, and providing the floor with a height higher than the expected tsunami height. By constructing this structure in a necessary place such as a town or a village along the coast, an attempt is made to secure an evacuation place for residents (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 9-184323

  However, the tsunami evacuation tower merely provides a floor surface higher than the ground, and does not have facilities for assisting activities when the residents evacuate or after evacuation. For this reason, residents cannot perform evacuation activities more reliably. Similarly, in the above tsunami evacuation tower, when the residents evacuate, they have to walk on their own or go up to the floor through a ladder or the like by themselves. For this reason, there is a possibility that the evacuation cannot be completed within a limited time for the above-mentioned movement restriction person or the like.

  Accordingly, the first object of the present invention is to provide a tower having a function capable of helping residents to evacuate when a tsunami occurs, and to make it easier for residents to evacuate on the tower. Let's assume the second issue.

  In order to solve the above first problem, the present invention provides various evacuation facilities for use during evacuation on a tower. If the tower is equipped with equipment, residents can be evacuated by using the equipment. In order to solve the second problem, the present invention provides a hoisting machine as the evacuation equipment. If a hoisting machine is used, a person or the like can be lifted, so even a person with limited mobility can easily be guided on the tower and does not need time to evacuate. For this reason, there exists an effect which can protect the life of a local resident more reliably.

  Since the present invention is configured as described above, when the tsunami occurs, the evacuation activities of the residents are assisted by the equipment provided in the tower, and the residents can be easily evacuated on the tower.

As a specific embodiment of the above means , a pair of metal columns 1 are erected at corresponding positions across the road R in the ground G, and these columns 1 are arranged in the width direction of the road R and in a direction perpendicular thereto. The struts 1 and the lateral frame 2 are connected to each other by an extending horizontal frame 2, and a structure is formed. The structure can accommodate personnel who are expected to evacuate at positions higher than the expected tsunami height. A floor surface 3 having an area and a safety fence 4 at the peripheral edge of the floor surface 3 are provided, and the support column 1, the horizontal frame 2, and the floor surface 3 respectively correspond to road building limits on the roadway immediately below. A tsunami evacuation tower which is provided at a position where space can be secured and which is provided with elevating equipment from the ground G to the floor 3 and evacuation equipment for use during evacuation on the floor 3 The lifting equipment is a stairs Each pair of struts 1 and 1 separated by the road R is arranged so as to pass the opposite side of the strut 1 from the road R side. An upper staircase whose upper end is connected to the floor surface 3, and the lower staircase is adjacent to the side of the pair of struts 1, 1 and extends horizontally longer than the distance between the struts 1, 1. It is characterized by forming a mountain shape having a pair of oblique straight stairs extending obliquely from the front and rear ends of the connecting bridge portion toward the ground G.

  Evacuation equipment is equipment that assists the activities when residents evacuate or after evacuation. For example, in addition to lighting that guides residents to be evacuated to the evacuation site, loudspeakers, lifting equipment, etc., stockpiled foods that can be used by residents who have completed evacuation, medical equipment, portable radio, communication equipment, portable lighting Various evacuation facilities such as appliances and facilities for storing or attaching them can be mentioned. By providing these facilities on the floor, evacuation of residents is helped.

  In addition, the said floor surface can also be installed in multiple steps | paragraphs in the up-down direction of the said structure as needed. In this way, even if the place (site) where the structure is built is a small area, if multiple floors are provided, the total area of the floor will increase. Capacity can be secured. Of course, in the case where a wide construction site can be secured, it is possible to cope with securing the accommodation capacity by expanding the area of the floor surface per step.

  The said structure WHEREIN: As the said evacuation equipment, the structure which provided the hoisting machine for a person and material raising / lowering can be employ | adopted, for example. If it does in this way, an evacuee will be lifted by using a hoisting machine as needed at the time of evacuation, and will be easily guided from the ground to the floor without walking by himself. For this reason, especially for those who are restricted in movement, the time until completion of evacuation can be greatly reduced compared to the conventional case. Moreover, since the hoisting machine can be used to carry materials onto the floor, it can be effectively used for evacuation activities.

  If the wire of the hoisting machine is completely wound up, the equipment related to the hoisting machine can be prevented from intervening on the ground, so when the tsunami arrives, the equipment is submerged or destroyed. Can avoid damage. Further, if an openable / closable hatch is provided on the floor surface directly under the hoisting machine, it is easy to guide an evacuee or materials that are raised by the hoisting machine to the floor surface.

  Further, in the configuration in which the hoisting machine is provided, the hoisting machine is attached to an arm that is installed at the end of the floor surface and is capable of turning in the horizontal direction, and the turning range of the arm is directly below the floor surface. It is possible to adopt a configuration in which the safety fence that is set in the direction including the edge and that faces the turning range of the arm can be opened and closed. In this way, the hoisting machine is used so as to project to the side of the structure, and when the evacuees or materials rise to the floor surface, the arm is directed toward the structure. If it turns, the evacuees, materials, etc. can be easily guided to the floor. At this time, since the safety fence provided on the floor surface can be opened and closed, if the safety fence is opened at the time of turning, the guidance of the evacuees can be the shortest path from the ground to the floor surface, so it is smooth It is. Moreover, according to this structure, since the said hatch does not necessarily need to be provided in a floor surface, a structure can be simplified.

  In particular, the structure is provided across the direction intersecting the road, and the support column, the lateral frame, and the floor surface are provided at positions where a space corresponding to the road building limit can be secured on the roadway directly below. Is adopted. Since roads are generally set as evacuation routes, if a tsunami evacuation tower is built by occupying the roads that are evacuation routes, the distance to the evacuation site can be shortened. In addition, when constructing a structure, it is sufficient to obtain permission to occupy the road, so there is no need to purchase or rent exclusive land in advance. Becomes easy.

  Further, in the case where the tsunami evacuation tower is provided across the road, when the hoisting machine is provided, a configuration in which the hoisting machine is provided on the floor surface immediately above the road can be adopted. . In this way, the hoisting machine can be used to move directly vertically from the road to the floor, which is convenient, and by providing a structure on the road that is the evacuation route, The moving distance can be further shortened.

  In addition, in the structure of any of the above structures, a structure in which a spiral slope from the ground to the floor surface is provided in the structure can be adopted as necessary. If there is a spiral slope, evacuees who use wheelchairs and the like can be guided more smoothly on the floor surface, which is effective in making it easier for residents to evacuate.

  Further, in the configuration in which the tsunami evacuation tower is provided across the road, if the structure is provided with stairs and / or slopes from the floor to the ground at both ends of the road, or both, It can be divided from both sides of the floor and can be climbed on the floor, and its structure can function as a pedestrian bridge in normal times.

  Further, when a photovoltaic power generation device is installed in the structure and electric power is required for the evacuation facility, part or all of the necessary electric power is supplied by the power generation of the solar power generation device. You may make it do. If it does in this way, if the predetermined electric power generation amount is ensured, it will become possible to operate the said evacuation equipment without receiving supply of electric power from others or at the time of a power failure. In addition, even when operating with the supply of power from others, it is possible to reduce the amount of power commensurate with the power generation of the photovoltaic power generation device from the amount of power consumed by the supply source, and when particularly desired Can also sell electricity during normal times.

  One embodiment will be described with reference to FIGS. The tower for tsunami evacuation in this embodiment is constructed by building the structure 10 on the road R, and the road R is effectively used as the installation location. As shown in FIG. 1, the structure 10 is provided across the direction intersecting the road R, and the support column 1, the lateral frame 2, and the floor surface 3 each secure a space corresponding to the road building limit on the roadway immediately below. It is built in consideration of the contents of regulations such as road laws, road traffic laws, various laws such as road structure ordinances, government ordinances, etc.

  Since roads are generally set as evacuation routes, if a tsunami evacuation tower is built by occupying the roads that are evacuation routes, the distance to the evacuation site can be shortened. In addition, if the building is built using roads, it will be easy to place evacuation towers at regular intervals along the road as long as other requirements for evacuation towers are met. It becomes easier for the person to specify the evacuation site.

  Further, in this embodiment, as shown in FIG. 1, a rescue-covered hatch 7 is provided on the floor surface 3, and an evacuee or material lifted from the ground G by the hoisting machine 6 is transferred to the floor surface 3. It serves as an entrance for leading up. If evacuation equipment is provided on the floor directly above the road, it can be moved directly from the road to the floor as shown in FIG. Can do. In general, it is not desirable to use a private car at the time of evacuation. However, when an emergency tsunami evacuates for an instant, it is possible to reduce the evacuation time by placing an emergency car or the like on the evacuation equipment for evacuation.

  Furthermore, in this embodiment, as shown in FIG. 3, for example, a lighting device 19 'is arranged substantially evenly using a landing place of three stairs, and the lighting effect is further improved. Moreover, the hangar 20 which stores the said stored food, various evacuation equipment, etc. is installed in the suitable location on the floor surface 3 as needed.

  As described above, the tsunami evacuation tower according to the present invention is not only a structure for evacuation but also has a great effect of more reliably protecting the lives of residents by evacuation facilities that help residents to evacuate. Have
