Description

  The present invention relates to a self-supporting emergency lifting device for a person who needs assistance and an attendant to quickly move to a high place such as a tsunami evacuation building when a tsunami or flood occurs.

  As is well known, many people were killed by the tsunami in the Great East Japan Earthquake. However, what is not well known is the sacrifice of those who need assistance (the elderly, the disabled, or pregnant women), which is said to be about twice that of healthy people. In addition, a considerable number of evacuation supporters such as fire brigade members and residents' association officers who tried to help those who need assistance were also sacrificed.

  In general, in the event of a primary evacuation to a high place such as an evacuation building in the event of a tsunami or flood, elderly people or people with physical disabilities compared to healthy people, or supporters such as pregnant women, Especially for wheelchair users, even if there is a supporter, it is very difficult to move to a high place in a short time. Evacuation supporters such as fire brigade members tend to be delayed.

For these reasons, Article 9 Paragraph 1 and Paragraph 3 of the “Act on Promotion of Tsunami Countermeasures” enforced on June 24, 2011, “Evacuation of persons requiring special consideration such as those requiring assistance. "Efforts must be made to develop the necessary system and take measures to evacuate quickly and smoothly."
In addition, the Cabinet Office and the Central Disaster Prevention Council (held on March 26, 2012) were to ensure thorough implementation of the “15-minute rule” (the time during which firefighters' evacuation supporters can engage in activities). Even so, a device that can quickly move to a higher place is required to eliminate the time constraint.

  From the above, it is an urgent issue to provide a device that can quickly move a person who needs assistance and those evacuation supporters to a high place.

  3.11 After the earthquake, each municipality on the coast of each prefecture has been energetically promoting the designation of tsunami evacuation buildings and the installation of evacuation towers. proceeding. However, since these evacuation towers have only stairs and slopes, the evacuation scheme for those requiring assistance must be evacuated with the help of a caregiver in a short time, which is extremely difficult.

  According to the legal system, the evacuation guidelines in Japan currently support evacuation methods for those who need assistance with mutual assistance, that is, only with help from neighboring residents, and considering the actual evacuation, The reality is that this is inadequate.

  Specifically, conventional evacuation routes such as tsunamis use stairs or slopes attached to tsunami evacuation buildings, tsunami evacuation towers, etc. as moving means. It is handled with things. This takes a considerable amount of time and effort for the supporter, and even if time constraints are taken into account, several supporters are needed to support some supporters, It may be difficult to guide the people who need assistance.

  On the other hand, the existing tsunami evacuation towers, etc., do not meet the height expected to be revised after the Great East Japan Earthquake, so the number of evacuation buildings designated by the local government must be increased as soon as possible. . When evacuating on the stairs attached to this designated evacuation building, as mentioned above, it will be very difficult for both the supporter and the supporter.

  As these countermeasures, some sort of lifting device should be added to the evacuation tower or the like. For example, there is a tsunami evacuation device proposed in Patent Document 1.

JP 2008-14112 A

The tsunami evacuation device according to Patent Document 1 includes a base portion configured by disposing a lower outer strut on the outer periphery of a plurality of lower inner struts, and an upper inner portion disposed above the lower inner strut. And a tower section composed of support columns.
An evacuation stage is constructed at the top of the tower, and a stairs and a simple elevator are provided between the evacuation stage and the ground.

In this tsunami evacuation device, when an earthquake occurs, the evacuation stage is evacuated to an evacuation stage constructed at the top of the tower.
For this reason, the tower part and the base part that supports the tower part must have a structure that can withstand large external forces that are difficult to imagine, such as collision of suspended solids caused by tsunami and buoyancy caused by tsunami. However, there is a problem that the equipment cost is increased and the spread is limited.
In addition, the evacuation stage built at the top of the tower section has a limited evacuation space and a limited number of evacuees. At the same time, there is also a limited space for stockpiles, so you can stay for a long time. There is also the problem that it is difficult.

  The present invention has been made in view of the above-described problems, and an object thereof is to provide a self-supporting emergency lifting apparatus that can be installed relatively inexpensively and can evacuate more people. It is what.

In order to achieve the above-mentioned object,

A suspension bridge body that spans the evacuation building is provided at a predetermined height position of the self-supporting tower, and a carrier that moves up and down between the suspension bridge body and the ground is provided (first invention). .

  In the present invention, it is preferable that a pair of passenger doors are arranged on the carrier so as to face each other on the side where the suspension bridge body is provided and on the opposite side (second invention).

  In the present invention, the self-supporting tower is preferably equipped with an escape staircase (third invention).

In the present invention, a person requiring assistance or an evacuation supporter is lifted from the ground by a carrier to a height position where a bridge body is provided. After that, the person who needs assistance or the evacuation support person is made to evacuate to the adjacent evacuation building across the bridge.
According to the present invention, the self-supporting tower is installed independently from the evacuation building, and the evacuation building and the self-supporting tower are separated from each other. There is no need to consider a large external force that is difficult to assume, a more appropriate design is possible based on the standardized load, and the foundation and the structure can be installed relatively inexpensively and easily. In addition, the evacuation building has sufficient space for evacuation space and stockpile, so that more people can be evacuated and evacuees can stay for a long time.

  By adopting the configuration of the second invention, that is, by having a structure in which the entrance doors are separately provided so as to face each other in the transporter and can pass through, when entering the transporter from the entrance door on one side There is an advantage that it is easier to get on and off with a wheelchair because it is possible to get out of the entrance door on the other side in the same direction without changing the direction.

  By adopting the configuration of the third invention, even if the stairs in the evacuation building cannot be used due to the rush of evacuees or being blocked by rubble, etc., the evacuation stairs equipped in the self-supporting tower are used. You can evacuate. In the unlikely event that the lifting / lowering operation of the carrier is hindered, it is possible to evacuate using the evacuation stairs equipped in the independent tower.

<Description of effects>
The evacuation activity using the self-supporting disaster prevention lifting apparatus 1 configured as described above is as follows.
That is, when a tsunami, flood, or the like occurs, a person who needs assistance or an evacuation support person gathers on the first floor of the independent tower 3. Next, the entrance / exit door 14 a on one side of the transporter 14 is opened to get into the transporter 14. After closing the entrance / exit door 14a on one side, the transporter 14 is raised, stopped at the rooftop where the first suspension bridge body 12 is provided, the entrance / exit door 14b on the other side of the transporter 14 is opened, and the transporter 14 gets off. Then, the bridge bridge 12 is evacuated to the adjacent evacuation building 2.

According to the self-supporting emergency lifting apparatus 1 of the present embodiment, the following operational effects can be obtained.
(1) Since the self-supporting tower 3 is installed independently of the evacuation building 2 and the evacuation building 2 and the self-supporting tower 3 are separated from each other, assumptions such as collision of floating objects due to tsunami and buoyancy due to tsunami Therefore, it is not necessary to consider a large external force that is difficult to perform, and more appropriate design is possible based on a standardized load, and the foundation and the structure can be installed relatively inexpensively and easily.
(2) Because the evacuation destination is a large number of evacuation buildings 2 in the municipalities, the evacuation space is wide and the stocking during an earthquake is expected indoors. You can stay for hours.
(3) Since the entrance / exit doors 14a and 14b are separately provided so as to oppose each other in the transporter 14, the structure is such that the entrance / exit door 14a and 14b can pass through. In this way, it is possible to exit from the entrance door 14b on the other side in the same direction, and there is an advantage that it is particularly easy to get on and off with a wheelchair.
(4) Even if the stairs in the evacuation building 2 cannot be used due to the rush of evacuees or the stairs being blocked by rubble, etc., the evacuation can be evacuated using the evacuation stairs 4 provided in the self-supporting tower 3. . Even if the lifting / lowering operation of the transporter 14 is obstructed, there is a landing 16 that connects to the evacuation stairs 4 on each floor. After stopping at the nearest floor, the landing 11 and the landing 16 are passed through. You can evacuate from the evacuation stairs 4.
(5) Since the main structural portion of the self-supporting tower 3 has a highly open structure without a sealed outer wall or the like, it can escape without being confined in any case.
(6) Since it is a self-supporting structure independent of the evacuation building 2, there is an advantage that the earthquake resistance of the evacuation building 2 is not affected.
(7) Since a combination of rack and pinion is used as the lifting and lowering drive mechanism of the transporter 14, there is no risk of wires tangling during an earthquake unlike a wire-type elevator, and stable operation is possible and maintenance is possible. Can also be done easily.
(8) As the frame structure in the X direction (left and right direction) of each floor of the self-supporting tower 3, mainly a combination of a ramen structure and a brace structure using braces 3c as appropriate is used, ensuring seismic resistance. However, the boarding / alighting width of the transporter 14 can be made wider, and a large number of evacuees including those requiring assistance in wheelchair use can be evacuated in large quantities.
(9) Since the evacuation destination is a large number of evacuation buildings 2 etc. in the municipality, the evacuation space is wide and it is expected to be stocked during an earthquake indoors, so that it is possible to stay for a long time.
(10) Since the number of evacuation buildings 2 and the like is overwhelmingly larger than that of the conventional evacuation tower and the scale is large, the time until arrival is overwhelmingly short and many people can be rescued.

  As mentioned above, although the self-supporting emergency lifting device of the present invention has been described based on one embodiment, the present invention is not limited to the configuration described in the above embodiment, and as appropriate without departing from the spirit thereof. The configuration can be changed.

For example, in the above embodiment, the example in which the evacuation building 2 is adopted as the evacuation building is shown. However, the present invention is not limited to this, and the evacuation building 2 is replaced with an existing evacuation tower, a mountain, Elevation evacuation stages, etc. installed at a small height on the hill are also included in the concept of evacuation buildings.
As a structure in which the floors in the self-supporting tower 3 are combined as a unit, there can be a mode in which the required change in height is supported.

  Since the self-supporting lifting device for disaster prevention according to the present invention has characteristics that it can be installed relatively inexpensively and can evacuate more people, it can be used for evacuation from tsunamis and floods. Can be suitably used.
