Description

  The present invention relates to an evacuation building.

  In areas where tsunami attacks are expected, it is necessary to secure an evacuation site at a high place. Although hills and high-rise buildings can be used as evacuation sites, it is necessary to construct evacuation buildings that can withstand tsunamis in areas where there are few high-rise buildings. As this type of evacuation building, the evacuation tower of Patent Document 1 is known.

Japanese Patent No. 3911615

  Patent Document 1 describes an example in which a plurality of unit-type room structures are stacked on the ground surface inside the evacuation tower. This unit-type room structure is used daily before the arrival of the tsunami. It is not expected to be used after the tsunami has been pulled. In addition, this unit type room structure is submerged when the tsunami arrives and becomes unusable, but it is arranged so as not to escape from the evacuation tower, so it cannot be removed easily and remains in the evacuation tower. Must be left behind.

  As described above, the evacuation building of Patent Document 1 is assumed to be used until the arrival of the tsunami, and is not suitable as a place for evacuation life after a large tsunami or a large earthquake.

  From such a viewpoint, an object of the present invention is to provide an evacuation building that can be used as an evacuation place when a tsunami arrives and can be used as an evacuation life place after a disaster.

  The present invention for solving the above problems is a multi-storey evacuation building having an evacuation space at the time of the arrival of a tsunami on at least the top floor, and for installing a housing for carrying in after a disaster on at least one floor It is characterized by having a housing installation space.

  If you try to secure land for temporary housing after a disaster such as a major earthquake or tsunami, you may not be able to quickly supply temporary housing by adjusting the interests. According to the building, since the housing installation space for installing the housing for housing is secured in advance, the housing for housing can be installed quickly after a disaster. That is, the evacuation building according to the present invention can be used as an evacuation place when a tsunami arrives, and can be used as a temporary housing installation place after a disaster.

  The evacuation building according to the present invention may include a core structure and an outer structure arranged so as to surround the core structure. In this case, it is preferable that at least one of the core structure and the outer structure is provided with an up / down passage to an upper floor or a lower floor, and the housing installation space is provided in the outer structure.

  If the housing installation space is provided in the outer structure, the work for carrying in the housing for housing becomes easy. In addition, since two inner and outer structures (a core structure and an outer structure) are formed, it is possible to easily ensure a horizontal proof stress exceeding the seismic force and tsunami wave force.

  When providing a plurality of housing installation spaces on at least one floor of the outer structure, the outer structures may be arranged radially with the core structure as the center. In this way, when a housing is installed in each housing installation space, adjacent housings on the same floor will be separated appropriately, thus ensuring the privacy of the refugee become.

  In the case where the slope is a part of the lifting / lowering passage, it may be provided in the outer structure. When the slope is provided on the outer structure, the slope length can be increased compared to the case where the slope is provided on the core structure, so that the slope of the slope can be made gentle, and thus barrier-free can be achieved. .

  Furthermore, if an evacuation passage leading to the evacuation space is formed by connecting a plurality of slopes via a landing, even elderly people and infants who cannot easily move up and down stairs and ladders can move quickly to the evacuation space. become.

  A support slab capable of supporting the housing for housing may be disposed on the outer structure. If the support installation slab having a wide area is used as a housing installation space, it is possible to deal with a residential housing of different dimensions.

  When the housing for housing is supported by a support slab, an access passage that connects the lift passage and the housing installation space may be provided on the support slab. In this way, a smooth flow line can be ensured.

  You may arrange | position the beam which can support the said housing | casing for housing | casing in the said outer side structure. In this way, it is possible to reduce the cost because it eliminates the trouble of forming a permanent flooring on the outer structure.

  When the housing for housing is supported by a beam of an outer structure, a floor slab is provided in the core structure, and an access passage that connects the lift passage and the housing installation space is provided on the floor slab. Good. If it does in this way, even if it does not provide a floor slab in the whole floor in each floor of an outside structure, a smooth flow line can be secured.

  The beam may be arranged outside the housing installation space. If it does in this way, it will become possible to hang a housing for residence to a lower floor through the space surrounded by a beam. In this case, the residential housing is supported on the beam via at least one of a bracket projecting from the beam toward the housing installation space and a bracket projecting from the residential housing toward the beam. It is good to let them. In addition, it is preferable that the bracket can be moved back and forth, or can be extended and retracted or turned as necessary so that the bracket does not get in the way when the housing for housing is suspended.

  If an installation opening that allows the housing to be inserted vertically is formed in the evacuation space, the housing can be suspended on the lower floor through the installation opening. In this case, the installation opening may be covered with a lid that can support and remove the evacuees. If it does in this way, while being able to avoid the reduction | decrease of an evacuation space, it becomes possible to ensure the carrying-in route of a housing | casing for housing | casing rapidly after a disaster only by removing a cover material.

  Moreover, when providing a housing | casing installation space in the area | region enclosed with the beam, it is good to cover a housing | casing installation space with the lid | cover material which can support an evacuee and is removable. In this way, the housing installation space can be used as an evacuation space, and after a disaster, it is possible to quickly secure a carry-in route for a residential housing simply by removing the lid.

  Further, if an opening for installation through which the housing for housing can be inserted is formed on the outer peripheral side surface of the outer structure, the housing for the upper floor is installed prior to the housing for the lower floor. This makes it possible to freely set the installation order of the housings for residence.

  According to the present invention, it can be used as an evacuation place when a tsunami arrives, and can be used as a temporary housing place after a disaster.

This is preferable because it is easy for evacuees to use. In addition, a fall prevention fence is installed in a portion where there is a possibility of falling in the passage portion after the evacuation space S1 or the housing K is installed.

Thus, the effects of the evacuation building T2 are as follows.
According to the evacuation building T2, since the housing installation space S2 for installing the housing for housing K is secured in advance, the housing for housing K can be installed quickly after a disaster. That is, the evacuation building T2 can be used as an evacuation place when a tsunami arrives, and can be used as a temporary housing installation place after a disaster.

  In the evacuation building T2, the housing installation space S2 is provided in the outer structure 4, so that the work for carrying in the housing K is facilitated. In addition, since the two inner and outer structures (the core structure 3 and the outer structure 4) are formed, it is possible to easily ensure the horizontal proof stress exceeding the seismic force and tsunami wave force.

  In the evacuation building T2, a plurality of housing installation spaces S2, S2, and S2 are arranged radially with the core structure 3 as the center. Therefore, when the housing housing K is installed in each housing installation space S2, Adjacent housing cabinets K, K on the same floor are appropriately separated, and as a result, it is possible to ensure the privacy of refugees.

  In the evacuation building T <b> 2, the slope 47 is provided in the outer structure 4, so that the slope length can be increased as compared with the case where it is provided in the core structure 3. That is, according to the evacuation building T2, the slope of the slope 47 can be made gentle so that barrier-free operation can be achieved.

  In the evacuation building T2, the evacuation passage S3 is formed by connecting a plurality of slopes 47, 47,... Via the landing 46, so that evacuation spaces S1 can be used even for elderly people and infants who have difficulty in raising and lowering stairs and ladders. It becomes possible to move quickly.

  In the evacuation building T2, the housing K is supported by the support frames (the inner circumferential beam 32, the outer circumferential beam 42, and the connecting beams 43 and 43), and a permanent flooring is formed in the housing support frame. As a result, the cost can be reduced.

  In the evacuation building T2, a part of the access passage that connects the lifting passage (slope 47, staircase 48) and the housing installation space S2 is provided on the floor slab 33 of the core structure 3, so that the outer structure Even if a permanent flooring is not formed over the entire surface of 4, a smooth flow line can be secured.

  Further, in the evacuation building T2, the installation opening 4c is formed in the area of the evacuation space S1 that is the housing installation space S2, but this installation opening 4c (that is, the housing installation space S2). Since the cover 52 is covered, the reduction of the evacuation space S1 can be avoided, and after the disaster, it is possible to quickly secure the carry-in route for the housing K by simply removing the cover 52. It becomes.

  The structural forms of the core structure 3 and the outer structure 4 may be changed as appropriate, and the structure types of the members constituting the core structure 3 and the outer structure 4 may be changed as appropriate.

  In the present embodiment, the planar shape of the core structure 3 is a hexagon, but it may be a circle, an ellipse, or a polygon other than a hexagon. Of course, the planar shape of the outer structure 4 may be changed.
