Description

[Technical Field]

[0001] The present invention relates to an evacuation facility equipped with a heliport that can be used effectively during normal times and can be used in the event of a disaster, particularly a flood. [Background technology]

[0002] In recent years, climate change has become more severe, causing frequent flooding in various regions. In such cases, there is a growing demand for facilities that can be used by local residents for evacuation and that also have a heliport on the roof.

[0003] For example, Patent Document 1 discloses the technical concept of an elevated tsunami evacuation shelter that aims to provide an elevated tsunami evacuation shelter that allows residents near the coast to evacuate quickly when a tsunami occurs, and that even the elderly and children can evacuate easily and quickly, and that can supply necessary supplies such as food to evacuees at higher altitudes, and that allows evacuees to evacuate to another safe location in an emergency.The tsunami evacuation shelter consists of pillars driven into the ground, an evacuation platform supported by the pillars at a predetermined height above ground, and lifting means that allows movement between the ground surface and the evacuation platform, and the lifting means consists of stairs and a gondola.

[0004] However, this tsunami evacuation shelter is designed primarily for evacuation from tsunamis, and the facilities are problematic in that they require large-scale construction.

[0005] There is also a heliport on the roof, but the type of heliport it is has not been disclosed, so there is a problem in that its practicality and economic viability are unclear.

[0006] Furthermore, no consideration has been given to its use during normal times other than when a tsunami occurs, which poses a major problem from an economic standpoint. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-112087 Summary of the Invention [Problem to be solved by the invention]

[0008] The problem to be solved is to provide an evacuation facility with a heliport for flood control that can be adapted to floods, can be used effectively during normal times, and is equipped with a heliport that is economical and practical. [Means for solving the problem]

[0009] In order to solve the above problem, a first aspect of the present invention is an evacuation facility with a heliport for flood control, - intermediate floors above ground level with floor levels above the expected flood inundation height; - a sealable space provided on the intermediate floor that is available for public use during normal times and that can be used as an evacuation area in the event of a flood; -An aluminum deck heliport located above the intermediate floor, which can be used as a rendezvous point for doctor helicopters during normal times and allows the transport of people and goods by helicopter in the event of a flood; - A step eliminator for lifting and lowering a stretcher between the ground floor or the intermediate floor and the aluminum deck heliport; The present invention is characterized by having the following.

[0010] A doctor helicopter is a helicopter equipped with medical equipment for emergency medical care. It is a dedicated helicopter that travels to the scene of an emergency with a doctor and nurse on board and can provide life-saving medical care (air ambulance) to the patient until they are transported from the scene to a medical institution, but it may not have all of these functions.

[0011] The height of the middle floor is based on the assumption of flood level, not a huge tsunami. Therefore, the structure is relatively simple, construction costs are low, and it is highly economical.

[0012] In addition, the airtight spaces on the intermediate floors that can be used for evacuation, such as rooms with ceilings, walls, and doors, can be used for public purposes even during normal times, such as for local meetings or hobby classes.

[0013] In addition, the heliport is made of aluminum deck, which is advantageous in that the heliport itself is lightweight and can be completed in a short period of time. Furthermore, because the heliport is lightweight, the structure of the building itself can withstand its weight. Ba Therefore, the structure can be simplified.

[0014] Furthermore, the heliport is normally used as a rendezvous point for doctor helicopters (a point where transport by land is switched to transport by helicopter).To this end, it is equipped with a step-eliminating device to lift injured or sick people lying on stretchers (simple beds with wheels) from the ground floor or intermediate floors to the heliport on the roof.

[0015] A step-eliminating device has a pantograph structure and is raised and lowered hydraulically or electrically, and is also known as a scissor lift or table lift.

[0016] According to this, stairs cannot be used as a means of raising and lowering a stretcher; a slope requires a large space; and an elevator would be extremely costly and technically difficult to use in order to avoid protruding from the heliport surface. However, a step-leveling device has a simple structure and is easy to install, providing a means of raising and lowering that achieves the desired purpose at a reduced cost.

[0017] Next, the second aspect of the present invention is an evacuation facility with a heliport for flood control of the first aspect, which may further be characterized by having a columnar structure for reducing the force of the flood, erected approximately vertically on the side from which the flood is approaching.

[0018] Multiple pillar structures, preferably three, should be installed. "Approximately vertical" includes being tilted slightly from the vertical depending on the direction of the flood. This reduces the force of the flood and eliminates the risk of damage to evacuation facilities due to floating debris. [Effects of the Invention]

[0019] As described above, the present invention makes it possible to provide an evacuation facility with a flood-control heliport that can be adapted to floods, can be used effectively during normal times, and is equipped with a heliport that is highly economical and practical. [Brief explanation of the drawings]

[0020] [Figure 1] 1 is a perspective view of an evacuation facility with a heliport for flood control according to one embodiment of the present invention. FIG. [Figure 2] 1 is a perspective view of a step-eliminating device for an evacuation facility according to one embodiment of the present invention. FIG.

[0021] An embodiment of the present invention will be described with reference to the drawings. The following description will be a schematic illustration of the scope necessary for the description of the present invention to achieve the object of the present invention, and will mainly describe the scope necessary for the description of the relevant parts of the present invention, with the omitted parts being based on known techniques.

[0022] Figure 1 is a perspective view of an evacuation facility with a flood control heliport according to one embodiment of the present invention, with a portion cut away for illustrative purposes. The evacuation facility with a flood control heliport 1 has a second floor 20 and a rooftop 30 above a ground floor 10, constructed with a sturdy structure that can withstand floods.

[0023] The ground floor 10 is a piloti consisting almost entirely of columns, and is intended to be used as a parking lot, etc., and this area may be flooded in the event of a flood.

[0024] Also, an elevator 11 to the second floor 20 is provided on the ground floor 10. In addition, there are provided other lifting means that do not require power, such as an external staircase 12 and a slope (not shown), and the building may also have lifting means that require power, such as an escalator.

[0025] However, it should be assumed that powered lifting means may become unusable in the event of a flood.

[0026] Next, the second floor 20 is a floor with a floor surface, and is preferably at least 5 m above ground level. The height can be determined based on the expected flood height, and does not need to be as large as that required to cope with a massive tsunami.

[0027] Additionally, the second floor 20 has an enclosed space 21 separated by a floor, ceiling (which may be the same as the floor of the upper floor), walls, doors, windows, etc. This area is highly livable, equipped with electricity, gas, water, telephone, internet connection (Wi-Fi equipment), toilets, etc., and is normally used as a public facility such as a community center, or as an entertainment facility (for karaoke, hobby classes, etc.).

[0028] Furthermore, a storage warehouse (not shown) is provided on the second floor 20 to store emergency supplies such as rescue supplies in case of floods, food for evacuees, drinking water, etc., and also includes an emergency power supply facility (not shown).

[0029] It is preferable to locate the stockpile warehouse inside the sealed space 21, as this allows the contents to be stored safely for a long period of time, but it may also be located outside the sealed space 21 if appropriate measures are taken.

[0030] The rooftop section 30 is the top floor of the building having a floor surface, and the top surface is open. An aluminum deck heliport 40 is provided above the rooftop section 30.

[0031] The Aluminum Deck Heliport 40 is formed by combining deck materials made from aluminum alloy extrusions, and has a simple structure that is easy to construct, allowing for simplified processes and shorter construction times.It is also lightweight and made from aluminum, which has the advantage of allowing for a slimmer structure for the building itself.

[0032] The Aluminum Deck Heliport 40 is designed for doctor helicopters and must meet the minimum standards for an off-airport takeoff and landing site, with the dimensions of the landing strip being approximately 17m x 21m.

[0033] Furthermore, in anticipation of the possibility of disaster prevention aircraft flying in and landing in accordance with Article 81-2 of the Aviation Act (special provisions for search and rescue), it is desirable that the floor and pillars be strong enough to allow an 11-ton helicopter to land.

[0034] From the second floor 20 or the rooftop 30 to the landing and takeoff surface of the aluminum deck heliport 40 (the flat area where helicopters take off and land), there is provided an elevator such as a staircase or a ramp (not shown), which allows ambulatory users to ascend and descend to the aluminum deck heliport 40.

[0035] Furthermore, a step-eliminating device 50 extends from the second floor portion 20 through the roof portion 30 to a position slightly lower than the takeoff and landing surface of the aluminum deck heliport 40.

[0036] Furthermore, an enclosure 32 is provided on the top of the step-eliminating device 50 to protect it from wind and rain, covering three sides and the top, except for the side through which people enter and exit the step-eliminating device 50.

[0037] In FIG. 1, for the sake of explanation, a part of the enclosure 32 is cut away to show the stretcher mounting portion 52 of the step-eliminating device 50.

[0038] FIG. 2 is a perspective view of a step-eliminating device for an evacuation facility according to one embodiment of the present invention, in which a pantograph-like mechanism 51 is raised and lowered hydraulically or electrically to raise and lower a stretcher placed on a stretcher mounting section 52.

[0039] Here, it is preferable that the stretcher mounting section 52 has walls 522 on three sides excluding the entrance side on a substantially horizontal, flat bottom plate 521 having a base area large enough to accommodate a stretcher. In this way, the attendant can safely ascend and descend together with the stretcher.

[0040] Furthermore, the uppermost end of the stretcher loading section 52 of the step-eliminating vehicle 50 is positioned slightly lower than the takeoff and landing surface of the aluminum deck heliport 40, but after the stretcher is carried out here, it can be reached by using the gentle slope 31 and a gentle curve (not shown) to reach the takeoff and landing surface of the aluminum deck heliport 40.

[0041] In this way, by placing a stretcher on the stretcher loading section 52, raising the top surface of the bottom plate 521 to a position slightly lower than the takeoff and landing surface of the aluminum deck heliport 40, and then using the wheels provided on the stretcher to move it up the gentle slope 31, the stretcher can be smoothly moved to the takeoff and landing surface.

[0042] On the other hand, by positioning the stretcher loading section 52 slightly below the takeoff and landing surface, even including the enclosure 32, any protruding parts that could hinder the helicopter's takeoff and landing are kept low, so that helicopter operation is not impeded, and an injured person lying in a bed can be transferred to the helicopter using the step-eliminating device 50, which is a relatively simple and low-cost device.

[0043] Although the lifting height of the top surface of the bottom plate 521 of the step-eliminating device 50 is set from the second floor 20 to just below the takeoff and landing surface of the aluminum deck heliport 40, this is not limitative and the top surface of the bottom plate 521 may be raised to approximately the same height as the takeoff and landing surface of the aluminum deck heliport 40, provided that it does not interfere with helicopter takeoff and landing. In this case, there is no need to provide a slope.

[0044] Also, depending on the situation, it may be possible to extend from the ground floor 10 to the takeoff and landing surface or slightly below, rather than from the second floor 20.

[0045] The step-eliminating mechanism does not have to be a pantograph-type mechanism and may be some other ascending / descending means, but it is desirable that the protruding height from the takeoff and landing surface of the aluminum deck heliport 40 be as small as possible.

[0046] Furthermore, as part of the evacuation facility with flood control heliport 1, pillar structures 60 for reducing flood force are provided on the outside of the structure. These pillar structures 60 are preferably reinforced concrete columns, and three of them are provided standing almost vertically.

[0047] Here, the spacing between the columnar structures 60 for reducing flood force is dimensioned to prevent large floating objects, such as houses or automobiles, from passing through in order to prevent them from directly crashing into the main body of the evacuation facility 1 with a flood control heliport and causing damage.

[0048] Next, the operation of the flood control evacuation facility 1 with heliport configured as described above will be described.

[0049] Under normal circumstances, local residents can use various means of elevators to go from the ground floor 10 to the second floor 20, and use the enclosed space 21 on the second floor 20 as a community center or a place for various entertainment and business purposes.

[0050] Even during normal times, if an injured or ill person needs to be transported by a doctor helicopter, this evacuation facility 1 with a flood control heliport can be used as a rendezvous point (a point where transport by land can be switched to transport by helicopter).

[0051] In other words, injured or sick people who do not require a stretcher can, with the help of a caregiver, travel from the ground floor 10 via the second floor 20 to the aluminum deck heliport 40 using various means of elevating, and then board the doctor helicopter that has arrived.

[0052] Meanwhile, injured people lying on stretchers who are unable to move on their own can use elevators or other means to go up to the second floor 20 and wait for the arrival of the doctor helicopter.

[0053] The step-eliminating device 50 is stopped so that the upper surface of the bottom plate 521 of its stretcher mounting portion 52 is at the same height as the floor surface of the second floor section 20. If there is a slight step between the floor surface of the second floor section 20 and the upper surface of the bottom plate 521 of the step-eliminating device 50, this can be absorbed by a slope or the like.

[0054] When the doctor helicopter arrives, the stretcher is placed on the stretcher mounting section 52 of the step-eliminating device 50, and the pantograph-like mechanism 51 of the step-eliminating device 50 is activated to raise the upper surface of the stretcher mounting section 52 to the highest point slightly below the takeoff and landing surface of the aluminum deck heliport 40.

[0055] In this state, the stretcher is equipped with wheels for transportation, so that the caregiver can easily move it along the slope 31 to the landing and takeoff surface of the aluminum deck heliport 40, making it possible for the patient to board the doctor helicopter.

[0056] Next, in the event of a flood, evacuees will evacuate from the ground floor 10 to the enclosed space 21 on the second floor 20 using various elevators.

[0057] Here, elevators, escalators, and other means of ascent that require power can be used in the event of a power outage if they are equipped with emergency power supply equipment. However, if the floodwaters progress, they may become unusable, in which case another means of ascent that does not require power, such as the exterior staircase 12, should be used.

[0058] There is a stockpile warehouse in or near the enclosed space 21, so evacuees can use the supplies there while waiting for the flood to subside or rescue to occur.

[0059] When using the aluminum deck heliport 40 for rescue, just as in normal times, various types of lifting and descending means are used to reach the landing and takeoff surface of the aluminum deck heliport 40 and board the rescue helicopter.

[0060] In particular, during floods, there may be a need to transport people who are injured during evacuation or who require treatment due to being elderly, and there is a high demand for doctor helicopters among them, as dialysis patients require dialysis treatment once every two days.

[0061] Many of these injured or sick people are unable to move on their own, so as mentioned above, they can be lifted up to the landing and takeoff surface of the aluminum deck heliport 40 using a stretcher, step-eliminating device 50, and ramp 31.

[0062] Conversely, there is also a need to dispatch doctors and nurses to examine and treat evacuees, and the Aluminum Deck Heliport 40 will also be utilized for this purpose.

[0063] Furthermore, during a flood, if the water is forceful or if large floating objects, such as collapsed houses or cars, approach the main body of the evacuation facility, the flood force reduction columnar structure 60 can attenuate the force of the flood and prevent the floating objects from crashing into the main body of the evacuation facility, thereby ensuring the safety of the evacuation facility and the evacuees.

[0064] In the explanation so far, the evacuation facility with flood control heliport 1 has been described as having the ground floor 10, the second floor 20, and the rooftop 30, but it is also possible to provide multiple floors, such as a third or fourth floor, between the second floor 20 and the rooftop 30. An enclosed space may also be provided on these floors for use during normal times. These second floors and floors above are collectively referred to as intermediate floors. [Industrial Applicability]

[0065] The flood evacuation facility with a heliport of the present invention can be installed at a relatively low cost by providing an aluminum deck heliport at the flood evacuation facility, and can be used both in normal times and when a flood occurs, making it highly applicable industrially.
