Description

[Technical field]

[0001] The present invention relates to a cabin having a float structure. [Background technology]

[0002] Japan is one of the world's most earthquake-prone countries, and because it is an island nation, it often suffers damage from tsunamis that accompany earthquakes.

[0003] In March 2011, the Tohoku Pacific Ocean Earthquake and the accompanying tsunami (Great East Japan Earthquake) caused enormous damage, and recently, measures against tsunamis have become increasingly important.

[0004] In addition, there is said to be a 70% to 80% chance of a major Nankai Trough earthquake, which is expected to have an impact on many regions, occurring within the next 30 years. This makes it increasingly important to take measures to reduce disaster damage, including tsunamis, in the event of such a major Nankai Trough earthquake.

[0005] Under such circumstances, for example, floating buildings have recently become known that can be raised upwards by their own buoyancy when a tsunami occurs due to an earthquake, without the need for any work to raise the float (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2014-136939 A Summary of the Invention [Problem to be solved by the invention]

[0007] However, systems such as that described in Patent Document 1 only lift the building upwards, and cannot avoid a tsunami if it occurs and exceeds the lifting height.

[0008] Furthermore, the system described in Patent Document 1 has a limited range in which buildings can move around, and there is a possibility that the system may be caught up in rubble or soil caused by a tsunami or flood, or in fires that break out after a tsunami.

[0009] The present invention has been made to solve the above-mentioned problems, and provides, for example, a cabin with a floating structure that can ensure a safe space with the primary goal of saving lives in the event of a water disaster such as a tsunami. [Means for solving the problem]

[0010] (1) In order to solve the above problems, the present invention provides A cabin having a float structure that can rise to the water surface in the event of a disaster, With a pedestal, A main body having a waterproof outer shell, fixed to the base, and having an interior space formed by a frame structure and a hollow structure; a float portion that is formed on the base and around the lower portion of the main body portion and expands when a given gas is injected into the float portion when the disaster occurs; a weight portion attached to the base at or near the center of the base; Equipped with The total buoyancy provided by the base and the float portion is greater than the total weight of the cabin including the main body portion and the weight portion.

[0011] With this configuration, the present invention can float on the water surface due to buoyancy in the event of a water disaster such as a tsunami, and since the base is not fixed to the ground surface or any other fixed object, it can rise to the water surface and then float freely.

[0012] In addition, the present invention can achieve a low center of gravity by placing a weight at or near the center of the base, thereby preventing capsizing while airborne and preventing water from entering the interior space.

[0013] Therefore, if the present invention is installed in a home or other such place, it can protect evacuees inside the room even if a disaster occurs, and can easily provide a safe space that prioritizes saving lives.

[0014] In addition, "disasters" basically include water disasters such as tsunamis and floods, as well as disasters such as typhoons and landslides.

[0015] In addition, the term "pedestal" refers to a component that, when placed on the ground surface in the case of a building, serves as a structural component that serves as the so-called "foundation" of the building, and also functions as a structure that provides buoyancy in the event of a disaster.

[0016] In particular, it is preferable that the "base" be formed from a material capable of obtaining buoyancy, such as FRP (fiber reinforced plastic), but it may be formed from other materials, such as polystyrene foam and wood, as long as they are capable of obtaining buoyancy.

[0017] And, "having a waterproof function on the outer shell" means that at least the outer walls (including the outside of the ceiling) and other surfaces that come into contact with water, including rainwater, need to have a waterproof function, and the inner walls do not have to have a waterproof function. However, taking into consideration the possibility of the interior space becoming flooded due to damage, etc., the entire wall (including the ceiling and floor parts, as well as the inner part) may have a waterproof function.

[0018] Furthermore, the term "frame structure" refers to a structure in which a frame is formed as a core material, and building materials that form the walls, ceiling, floor, etc. are formed around the frame. In particular, the shape of the main body is not particularly limited as long as it is a frame structure, and may be, for example, a rectangular shape such as a rectangle, a solid shape derived from a circle such as a cylinder, or a dome shape.

[0019] In addition to the above, "formed around the periphery of the lower part of the main body" includes, for example, that it may be formed around the entire periphery, or that it may be formed at regular intervals rather than around the entire periphery.

[0020] In addition, "expands by injecting a given gas in the event of a disaster" refers to the fact that under normal circumstances the air chamber into which the gas is injected is in a collapsed state, and the "given gas" includes liquefied carbon dioxide (liquefied carbon dioxide gas), etc.

[0021] In addition, it is preferable that the "float section" is composed of numerous air chambers, for example, it is composed of multiple air chambers, and with regard to the injection of gas, it may be a manual type in which gas is injected based on the operation of an operator such as an evacuee, or an automatic type in which gas is automatically injected when water is detected.

[0022] (2) The present invention also provides The cabin according to claim 1, The main body is dome-shaped.

[0023] With this configuration, the present invention can maintain high robustness, and can therefore maintain the indoor space and protect the evacuees inside even in environments where the indoor space may be destroyed by landslides, typhoons, hurricanes, hail, tornadoes, etc.

[0024] The term "dome shape" basically refers to a hemispherical shape that covers the main body as a roof or a part of the roof, or a convex shape on a base similar to the hemispherical shape.

[0025] (3) The present invention also provides The surface of the outer shell is formed in a dimple shape.

[0026] With this configuration, the present invention prevents the wind flow blowing against the surface of the main body from moving away from the surface (retreating the separation point) due to the dimple shape, and the low pressure area is reduced, so that the air resistance of the wind blowing against the surface of the main body can be reduced and deflected, thereby improving the rollover resistance of the cabin.

[0027] (4) The present invention also provides a storage portion for storing the weight portion on a bottom surface of the base opposite to a surface on which the main body portion is formed; The device is configured to include a state control mechanism that changes the weight portion from a state stored in the storage portion to a state protruding downward when the weight portion rises to the water surface.

[0028] With this configuration, the present invention can improve the cabin's resistance to capsizing when floating on the water surface without causing any obstacles when installing the cabin itself on the ground, since the weight portion is stored in the base under normal circumstances.

[0029] (5) The present invention also provides The weight portion is A support attached to the base; and a weight attached to a second end portion different from the first end portion attached to the base.

[0030] With this configuration, the present invention can provide a cabin with a low center of gravity, thereby improving the cabin's resistance to capsizing; and, for example, if the weight has a shape that extends in one direction, such as a plate shape, fish shape, or spindle shape (torpedo shape), the direction of the cabin can be controlled in the vertical direction of the weight against the waves even while the cabin is floating, thereby improving stability while floating.

[0031] (6) The present invention also provides The float portion has a configuration in which an air chamber to which gas used for inflation is supplied is divided into small chambers.

[0032] With this configuration, the present invention can maintain the floating of the cabin by generating buoyancy in the other air chambers even if part of the float is damaged and cannot expand.

[0033] (7) The present invention also provides The outer shell of the frame of the main body is integrally formed from a waterproof material. , configuration.

[0034] With this configuration, the present invention can further improve the waterproofing of the main body made of, for example, FRP.

[0035] (8) The present invention also provides The main body has an escape exit formed at a position higher than the waterline for rescuing evacuees in the indoor space to the outside, The escape hatch is configured so that, in the event of a disaster and floating on the water surface, the escape hatch is formed in a shape that allows it to be opened from the indoor space side, but cannot be opened from the outside.

[0036] With this configuration, the present invention allows a person to easily escape to the outside even if it becomes difficult to remain in the indoor space, such as when the indoor space is flooded. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0038] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0039] The embodiment described below is an embodiment in which the cabin of the present invention is applied to a hut-like building connected to a residence, commonly known as a "detached house."

[0040] Furthermore, the disasters in this embodiment basically include water disasters such as tsunamis and floods, but may also include disasters such as typhoons and landslides. However, as long as the cabin in this embodiment is useful in the event of a disaster, it is not limited to these disasters.

[0041] [1] Overview of the cabin and its configuration First, an overview and a schematic configuration of a cabin 10 according to the present embodiment will be described with reference to Figs. 1 and 2.

[0042] FIG. 1 is a diagram showing the external configuration of the cabin 10 in this embodiment in normal times, and FIG. 2 is a diagram showing the external configuration of the cabin 10 in this embodiment in the event of a disaster.

[0043] The cabin 10 of this embodiment is a shelter whose main purpose is to protect the lives of people who are unable to evacuate when a disaster occurs, and has a structure that allows it to float up and float freely in the event of a tsunami, for example.

[0044] Moreover, unlike tsunami evacuation boats and tsunami shelters, the cabin 10 of this embodiment provides a living space in which people can live comfortably under normal circumstances, and has a configuration that can be provided at a cost that can be widely adopted. is doing.

[0045] On the other hand, the cabin 10 of this embodiment is basically an extension to the house that can be used on a daily basis, and also functions as a building that serves as a detached building to the main house.

[0046] For this reason, the cabin 10 of this embodiment has the function of allowing people to stay (evacuate) even when it becomes difficult to live in the main house due to an earthquake, fire, flood, etc., or during long-term flooding damage caused by a tsunami, etc.

[0047] Specifically, as shown in Figures 1 and 2, the cabin 10 has a front door (entrance / exit opening / closing member) 30 as an entrance and a window section 40 for ventilation or for letting in sunlight, and is composed of a base 100, a main body section 200, a float section 300, and a weight section 400.

[0048] In particular, the cabin 10 is configured so that the central bottom portion is the center of gravity of the entire cabin, and has a structure that will not capsize even if a 45 degree incline (tilt) occurs.

[0049] [2] Pedestal Next, the base 100 of this embodiment will be described with reference to Fig. 3 in addition to Fig. 1 and Fig. 2. Fig. 3 is a side view and a bottom view of the base 100 of this embodiment.

[0050] When the pedestal 100 is placed on the ground surface as a building, it serves as a structural member that serves as the so-called "foundation" of the building, and is formed from materials that function as a structure to obtain buoyancy in the event of a disaster.

[0051] Specifically, the base 100 is integrally formed from FRP (fiber reinforced plastic) with a thickness of 10 mm, and is configured in a cylindrical shape with a diameter of 7 m and a height of 0.5 m, for example.

[0052] As shown in FIGS. 1 to 3, a main body 200 is formed on the upper surface side of the base 100 with the center of the upper surface of the base 100 as a reference.

[0053] As shown in Figs. 1 to 3, a storage section 130 for storing a float section 300 is formed on the upper surface side of the base 100, in a peripheral section 120 where the main body section 200 is not formed.

[0054] For example, the storage section 130 may be constituted by a box formed inside the base 100 from the top surface of the base 100 toward the bottom surface thereof, or may be formed as a storage box on the top surface of the base 100.

[0055] It is preferable that the storage section 130 has a lid, and when it is formed by a box formed inside the base 100, the upper surface of the base 100 may function as the lid.

[0056] In particular, in the case of a manual type in which the float section 300 inflates by injecting gas based on the operator's instructions, the storage section 130 has a configuration in which the lid opens based on the evacuee's operation, and the lid opens automatically, for example, when a certain amount of water is detected on the base 100 instead of based on the operator's instructions.

[0057] In addition, when the float unit 300 is an automatic type, the storage unit 130 stores the float unit 300 in an automatic manner. The lid is configured to open in conjunction with the injection of gas into 00.

[0058] In this case, the storage section 130 may have a structure in which the lid opens using the force of the float section 300 expanding, or may have a mechanism in which the lid opens mechanically when instructions to the float section 300 are received from an evacuee or when water is automatically detected.

[0059] On the other hand, as shown in Figures 1 to 3, the underside of the base 100 (i.e., the surface that comes into contact with the ground under normal circumstances and that comes into contact with water in the event of a disaster) has a weight storage section 140 that stores the weight section 400 under normal circumstances.

[0060] That is, the cabin 10 has a weight storage section 140 for storing the weight section 400 on the bottom surface of the base 100 of this embodiment, which is the surface opposite to the surface on which the main body section 200 is formed.

[0061] In particular, the weight storage section 140 stores the weight section 400 so that it can move up and down due to the weight of the weight section 400 itself and the repulsive force from the ground surface on which it is placed, and is configured so that in the event of a disaster (specifically, when it rises to the water surface), the stored weight section 400 will protrude downward due to its own weight.

[0062] For example, the weight storage section 140 is composed of an opening 141 that opens to the bottom side, and a protrusion 142 that extends in the direction of the surface on which the lower surface of the opening 141 is formed and in the direction of blocking the opening 141 and has a predetermined length.

[0063] Furthermore, weight storage section 140 may be circular or rectangular in shape, as long as it is capable of storing weight section 400 and has a shape that allows weight section 400 to remain in weight storage section 140 even if weight section 400 protrudes downward due to its own weight during a disaster (specifically, when the weight section rises to the water surface).

[0064] In addition, the base 100 of this embodiment is preferably formed from FRP, but it may be formed from any material that can obtain buoyancy, such as polystyrene foam or wood, and that can be used as the foundation for a building.

[0065] [3] Main unit Next, the main body 200 of this embodiment will be described with reference to FIGS.

[0066] 4 is a frame structure diagram showing only the aluminum frame 220 of the main body 200 of this embodiment, and FIG. 5 is a cross-sectional view showing a cross section of a part of the outer shell 210 of this embodiment.

[0067] [3.1] Overview The main body 200 has a waterproof outer shell, is fixed to the base 100 by bolts or the like, and has a frame structure and a hollow structure for forming an interior space.

[0068] The main body 200 is formed three-dimensionally on the upper surface side of the base 100 in a dome shape with a diameter of 5 m and a height of 3 m, based on the center of the circle on the upper surface of the base 100 .

[0069] That is, the main body 200 has a hemispherical or hemispherical shape that is convex on the base 100 and covers the main body as a roof or a part thereof.

[0070] In addition, the main body 200 is, for example, 19 m 2 The house has a floor area of ​​approximately 10 tatami mats (approximately 10 tatami mats) and is designed as a house with an interior decoration similar to that of a normal residence. It also has windows 40 for letting in natural light and for ventilation, heating and cooling equipment such as air conditioners, electrical equipment such as LED lighting, and a front door 30 for entering and exiting the house.

[0071] [3.2] Structure The main body 200 has an outer shell 210 made of an aluminum frame structure to provide vibration-proofing, fire-proofing, waterproofing and load-bearing performance, forming a hollow structure.

[0072] In particular, the outer shell 210 of the main body 200 has a hard foam-type heat insulating material around a frame (ie, an aluminum frame) 220 as shown in FIG.

[0073] That is, an outer shell 210 outside an aluminum frame 220 of the main body 200 is integrally formed from a waterproof material.

[0074] As shown in FIG. 5, the outer shell 210 is formed by an outer wall 230 formed on the outside of the aluminum frame 220 and an inner wall 240 formed on the inside of the outer wall 230, and has a configuration that ensures space for a living space.

[0075] The aluminum frames 220 are arranged vertically and horizontally at predetermined intervals (for example, 18 cm intervals vertically and 90 cm intervals horizontally) so that the main body 200 has a dome shape.

[0076] That is, the aluminum frame 220 is formed as a core material of a frame structure, and an exterior wall is formed around the aluminum frame 220, and building materials that form an interior wall (including a ceiling and a floor) are attached thereto.

[0077] The exterior wall 230 is formed, for example, from resin by integral molding to prevent water leakage, includes a dome-shaped ceiling portion, and has a waterproof function on the surface that comes into contact with water, including rainwater on the outside.

[0078] As shown in FIG. 5, the outer surface of the outer wall 230 is dimpled, and a plurality of dimple-shaped recesses 231 are formed.

[0079] In other words, the dimple shape of the recess 231 prevents the flow of wind blowing against the surface of the main body from moving away from the surface (retreating the separation point), and the area of ​​low pressure is reduced, thereby reducing the air resistance of the wind blowing against the surface of the main body 200 and deflecting it, thereby improving the rollover resistance of the cabin 10.

[0080] Specifically, as described above, each recess 231 is provided to reduce air resistance, and has a deepest portion having a length of 10% of the diameter L (for example, approximately 50 mm to 200 mm).

[0081] As shown in FIG. 5, each recess 231 has a length such that the center point distance of the adjacent recess 231 is 150% of the diameter.

[0082] The center of each recess 231 is positioned so that the angle formed between the center of an adjacent first recess 231A and the center of a second recess 213B different from the adjacent first recess 213A is 60 degrees, as shown in FIG.

[0083] In addition, in FIG. 5, six recesses 213A are arranged relative to the recess 213 serving as a reference. 13B, 213C, 213D, 213E, 213F and 213G are arranged as an example.

[0084] The interior wall 240 is formed on the indoor side by a plaster board of a predetermined thickness (for example, 9.5 mm) and a fire-retardant wallpaper or flooring material attached to the surface of the plaster board.

[0085] Although the inner wall 240 does not have a waterproof function as described above, taking into consideration the possibility of water entering due to damage, etc., the entire wall (including the ceiling and floor portions as well as the inside portion) may have a waterproof function.

[0086] Furthermore, although the main body 200 is formed in a dome shape with a frame structure, it may be formed in a three-dimensional structure derived from a rectangular shape such as a rectangle, or a circular shape such as a cylinder.

[0087] [3.3]Escape exit The main body 200 may have an emergency escape hatch 250 formed at a position above the waterline.

[0088] In other words, the main body 200 is provided with an escape exit 250 formed at a position higher than the waterline in order to rescue evacuees in the indoor space to the outside, and when the escape exit 250 floats on the water surface in the event of a disaster, the escape exit 250 is formed in a shape that allows it to be opened from the indoor space side but cannot be opened from the outside.

[0089] As shown in FIG. 1, the escape hole is formed in an area where the aluminum frame 220 is not formed and where the dimpled recesses 213 are not formed as a boundary.

[0090] For example, the escape exit 250 has a shape (e.g., a circle with a diameter of 1 m or more) with a small opening on the indoor side and a large opening on the outdoor side, and opens only when a force is applied from the indoor side toward the outdoor side.

[0091] In addition, the escape hole 250 has a shape in which the area inside the outer shell 210 is narrower than the area outside, making it easy to destroy from the inside but difficult to destroy from the outside.

[0092] Specifically, the escape exit 250 functions as a wall under normal circumstances and will not be destroyed even if force is applied from the outside during a disaster, but has a structure that makes it easy to destroy from the inside in the event of a disaster when escape is necessary.

[0093] In other words, the escape exit 250 is a circular or rectangular opening formed at a predetermined position on the main body 200, e.g., with a pre-formed cut, and has a structure that allows it to come off when force is applied from the inside of the room to the outside, and also has a structure that increases the airtightness of the indoor space when force is applied from the outside to the inside of the room.

[0094] In the case of this embodiment, for example, when a force of about 20 kg is applied, the outer shell of the part serving as the escape exit is destroyed, making it possible to escape.

[0095] [3.4] Doorway opening and closing components, window components, etc. (Entrance / exit opening and closing components) As shown in Figs. 1 and 2, the entrance door opening / closing member (entrance) 30 is an entrance door made of general building materials and is fixed by an aluminum frame 220 so as to open inwards.

[0096] Moreover, a water stop 242 having a predetermined height is formed on the outer wall surface side of the entrance opening / closing member 30 to prevent water from entering. In particular, it is preferable that the water stop 31 has a height equal to or higher than the anticipated waterline (hereinafter also referred to as the "anticipated waterline").

[0097] The assumed waterline is calculated based on the total buoyancy calculated in advance and the total weight of the entire cabin 10 (including the maximum weight based on the maximum number of people staying there). (Window) The window portion 40 is fixed above the assumed waterline by an aluminum frame 220 and is made of general building materials. The window portion 40 is also provided with a storm shutter (not shown) to prevent damage or water intrusion.

[0098] [4] Float section Next, the float portion 300 of this embodiment will be described with reference to FIG.

[0099] As shown in FIG. 2, the float portion 300 is formed on the base 100 around the lower part of the main body portion 200, and is configured to expand when a given gas (e.g., liquefied carbon dioxide (liquefied carbon dioxide gas)) is injected in the event of a disaster.

[0100] In particular, the float portion 300 is used not only to obtain buoyancy but also as a shock-absorbing material to enhance resistance to obstacles and drifting objects.

[0101] For example, the float portion 300 is constructed in a cylindrical shape with a diameter of approximately 90 cm, with the outside made of high-strength nylon used in bulletproof vests, and stitched to prevent the float portion of the main body portion 200 from shattering.

[0102] Specifically, the float portion 300 is made up of a plurality of air chambers 310 so that even if one part is broken, the effect on the whole is limited, and each air chamber 310 is formed independently from the other air chambers 310.

[0103] That is, the float portion 300 has a configuration in which the air chamber to which the gas used for inflation is supplied is divided.

[0104] As shown in FIG. 2, the float unit 300 is normally stored on the upper surface of the base 100 with the air chamber into which the gas is injected folded up.

[0105] A given gas may be injected into each air chamber based on the operation of an operator, such as an evacuee present in the room (i.e., manual), or gas may be injected automatically upon detection of water (i.e., automatic).

[0106] The gas is stored in either the base 100 or the main body 200 in a tank such as a cylinder (not shown), and the tank and each air chamber are connected by a tube (not shown) or the like.

[0107] Furthermore, when gas is manually injected into each air chamber, this is carried out by a switch (not shown) installed in the main body 200.

[0108] Furthermore, in this embodiment, the float portion 300 is formed by a plurality of air chambers around the entire periphery of the lower portion of the main body portion 200, but it may be formed at regular intervals rather than around the entire periphery.

[0109] [5] Weight section Next, the weight section 400 of this embodiment will be described with reference to FIGS.

[0110] 6 and 7 are front and side views of the weight portion 400 of this embodiment, showing an example of the weight portion 400 stored within the bottom surface of the base 100, and an example of the weight portion 400 protruding from the bottom surface.

[0111] The weight portion 400 is attached to the base 100 at or near the center of the base 100 to lower the overall center of gravity and improve rollover resistance.

[0112] In particular, the weight section 400 is normally stored in the weight storage section 140, which is a U-shaped box located in the center of the bottom surface of the base 100, and is configured to protrude from the bottom surface of the base 100 in the event of a disaster (especially when it rises to the water surface).

[0113] That is, the weight section 400 is provided with a state control mechanism that changes the state from that stored in the weight storage section 140 to that protruding downward when the weight section 400 rises to the water surface.

[0114] Specifically, as shown in Figures 6 and 7, weight section 400 has a base 410 having a size larger than the size of the opening of weight storage section 140, a number of pillars 420 joined to base 410 as a foundation, and weights 430 joined to end sections (hereinafter referred to as "second end sections") of each pillar 420 different from the end section (hereinafter referred to as "first end section") to which base 410 is joined.

[0115] That is, the weight section 400 includes a support 420 attached to the base 100, and a weight 430 attached to a second end portion different from the first end portion attached to the base 100.

[0116] Therefore, in this embodiment, the cabin 10 has a low center of gravity, improving the resistance of the cabin 10 to capsizing, while the direction of the cabin can be controlled in the vertical direction of the weight relative to the waves even when the cabin is floating, thereby improving stability while floating.

[0117] The material, size, thickness, and the like of base 410 are not limited as long as it can join multiple supports 420 and is larger than the size of the opening of weight storage section 140.

[0118] Each pillar 420 is arranged at equal intervals, has a length that is shorter than the vertical length in the up-down direction of the weight storage section 140 (the direction in which the weight section 400 moves) that is perpendicular to the top surface of the base 100, and has a weight 420 joined to its second end, which is its tip.

[0119] Furthermore, each support 420 may be rod-shaped and extendable or foldable.

[0120] In particular, each support 420 has an extendable structure even if it protrudes from the bottom surface of the base 100 during a disaster, and has a structure that is not easily damaged even if the weight 430 collides with the ground (ocean bottom) or an obstacle. However, each support 420 may have a locking mechanism that prevents the protruding portion from being retracted when it protrudes from the bottom surface of the base 100 during a disaster.

[0121] Each weight 430 may be formed in a plate shape, a fish shape, or a spun shape to improve the rotation resistance of the cabin 10. It has a shape that extends in one direction like a cone (torpedo shape), and has a shape that allows the direction of the cabin to be controlled vertically to the direction in which waves and water currents occur, even when the cabin 10 is floating.

[0122] 6 and 7 show an example in which three spindle-shaped weights 430 are attached to the tip of the support 420 and are arranged in parallel and at equal intervals.

[0123] Moreover, in this embodiment, the weights 430 each have a weight of 200 kg, and the total weight is 600 kg.

[0124] [6] Mooring, etc.

[0125] (Mooring ropes and mooring rings) The cabin 10 may have mooring equipment and may be configured to prevent free floating depending on the situation, even in the event of a disaster.

[0126] Specifically, the cabin 10 has a mooring equipment consisting of a mooring rope with one end fixed to the ground or another building (not shown), and a mooring ring to which the other end of the mooring rope is tied.

[0127] The mooring ring is fixedly installed somewhere on the base 100, and is configured so that, at the instruction or operation of the evacuee, the mooring ring itself can be detached, for example by removing a pin using a wire or the like, and the part connected to the mooring rope can be released.

[0128] (Storage section) A predetermined space may be formed under the floor of the cabin 10. For example, the space stores items necessary for living in an evacuation shelter for several days, such as food and clothing, in addition to an emergency battery (having a capacity of, for example, about three days) to be used in the event of a disaster.

[0129] (Radioactive material blocking structure) An iron plate such as a lead plate may be incorporated inside the outer shell of the main body 200. In particular, it is preferable to have a lead plate on the indoor side of the aluminum frame 220 to block radioactive materials.

[0130] [7] Total weight and buoyancy Next, the relationship between the total weight and buoyancy in the cabin 10 of this embodiment will be described.

[0131] The cabin 10 of this embodiment has a configuration in which the total buoyancy obtained by the base 100 and the float portion 300 is greater than the total weight of the cabin 10 including the main body portion 200 and the weight portion 400.

[0132] Specifically, the cabin 10 of this embodiment has an overall weight of 700 kg (including the weight portion 400 having a weight of 600 kg).

[0133] On the other hand, as described above, if base 100 is a hollow structure made of 10 mm thick FRP, and the outer diameter of base 100 is 7 m, the outer diameter of main body 200 is 5 m, and the height of base 100 is 0.5 m, the hollow buoyancy is 12,560 kg.

[0134] In addition, the buoyancy of the hollow portion of the float section 300 is 5,722 kg, and if the float section 300 is not damaged, the buoyancy of the entire cabin 10 will be approximately 18,000 kg.

[0135] Therefore, the total buoyancy becomes sufficiently large so that the cabin 10 can rise to the water surface in the event of a disaster.

[0136] [8] Other The present invention is not limited to the above-described embodiment, and various modifications are possible. For example, a term cited as a broadly defined or synonymous term in the description in the specification or drawings can be replaced with a broadly defined or synonymous term in other descriptions in the specification or drawings.
