Description

Technical Field

[0001] The present invention relates to an evacuation tent unit, an evacuation tent, and an evacuation building.

Background Art

[0002] In the event of various natural disasters such as earthquakes, typhoons, and heavy rains, evacuees such as local residents will evacuate to nearby evacuation facilities such as gymnasiums, community halls, and halls as necessary. When a large number of evacuees take shelter in an evacuation facility, simple partitions may be installed from the perspective of ensuring privacy. In this way, while a minimum level of privacy is ensured by the partitions, if there are infectious disease patients among the evacuees who are suffering from various infectious diseases, sufficient infection prevention cannot be achieved with the partitions. Therefore, there are cases where attempts are made to install a tent in the evacuation facility and accommodate infectious disease patients inside the tent. By installing a tent in the evacuation facility, it becomes possible to accommodate not only infectious disease patients but also patients suffering from various diseases and the elderly, etc. in the tent.

[0003] Here, Patent Document 1 proposes a personal clean booth that enables effective removal of the influence of airborne aerosols that cause allergic diseases. This personal clean booth has a supply unit for clean air through a filter and a blowing unit for blowing out the clean air above or in the vicinity of the head, surrounds the clean air space with a sheet, and supports the sheet with a frame body suspended from the ceiling part or the wall part. Further, the clean air supply unit and the blowing unit are connected by a sheet duct.

Summary of the Invention

Problems to be Solved by the Invention

[0005] By applying the personal clean booth described in Patent Document 1 as a tent for evacuation shelters installed in the above-described evacuation shelter, for example, the inside of the tent for evacuation shelters can be placed in a clean environment.

[0006] Although not specifically described in Patent Document 1, it is considered that air is supplied to the clean air supply unit provided in the personal clean booth by an air supply fan. That is, air is supplied from one air supply fan to one personal clean booth. By the way, in the above-described evacuation shelter, since a large number of evacuees often evacuate at once, there may be a plurality of infectious disease patients among the evacuees. Therefore, it is preferable to install a plurality of tents for evacuation shelters in the evacuation shelter. On the other hand, since there is a limit to the space of the evacuation shelter, a tent unit for evacuation shelters that can suppress the occupied area as much as possible while installing as many tents for evacuation shelters as possible is desired.

[0007] The present invention has been made in view of the above problems, and an object thereof is to provide a tent unit for evacuation shelters, a tent for evacuation shelters, and an evacuation shelter building that can suppress the occupied area in the evacuation shelter as much as possible.

Means for Solving the Problems

[0008] In order to achieve the above object, one aspect of the tent unit for evacuation shelters according to the present invention is a tent unit for evacuation shelters including a plurality of tents for evacuation shelters, characterized in that an outdoor branch air duct communicates with each tent for evacuation shelters, each outdoor branch air duct communicates with a common main air duct, and the main air duct communicates with an outdoor air supply fan.

[0009] According to this aspect, by supplying air from a common outdoor air supply fan to a plurality of tents for evacuation shelters, the occupied area of the outdoor air supply fan can be suppressed, and as a result, the occupied area of the entire tent unit for evacuation shelters can be suppressed.

[0010] Also, in another aspect of the evacuation tent unit according to the present invention, the tent includes a floor framework composed of a plurality of shaft members, a ceiling framework, and a wall framework formed by the floor framework, the ceiling framework, and vertical members, a ceiling sheet that at least covers the ceiling framework, and a wall sheet that covers the wall framework and has an entrance / exit portion, a chamber installed inside the ceiling framework and provided with a lower panel in which a plurality of blow-in and suction holes are formed, Outdoor branch air ducts communicate with the chambers provided in each tent, respectively, each outdoor branch air duct communicates with a common main air duct, and the main air duct communicates with an outdoor air supply fan.

[0011] According to this aspect, air can be effectively supplied to the entire area inside the tent by supplying air into the tent through the chamber installed inside the ceiling framework that constitutes the framework.

[0012] Also, in another aspect of the evacuation tent unit according to the present invention, the outdoor air supply fan is characterized in that it can switch the air supplied to each tent between cold air and warm air.

[0013] According to this aspect, since the outdoor air supply fan can switch the air supplied to each tent between cold air and warm air, cold air or warm air at a desired temperature can be supplied to each tent according to the temperature and humidity inside the evacuation shelter, such as seasons and day and night.

[0014] Also, in another aspect of the evacuation tent unit according to the present invention, the evacuation tent includes a wall sheet having an entrance / exit portion and a ceiling sheet, The entrance / exit portion is formed by an entrance / exit slit provided in the wall sheet, On the left and right sides near the access slit in the wall sheet, first surface fasteners are respectively attached, and a second surface fastener is attached at a position away from the end of the access slit. When the left and right first surface fasteners are connected to each other, the access part is closed. It is characterized in that when the corresponding first surface fastener and the second surface fastener are connected, the access part is opened.

[0015] According to this aspect, by connecting the surface fasteners attached to the wall sheet to hold the opening / closing posture of the access part, the opening / closing of the access part and the holding of the opening / closing posture can be smoothly performed. In addition, since the second surface fastener is attached at a position away from the end of the access slit, when the first surface fastener and the second surface fastener near the access slit are connected, the access part can be opened widely.

[0016] In another aspect of the evacuation tent unit according to the present invention, the first surface fastener is attached to both the outdoor surface and the indoor surface of the wall sheet.

[0017] According to this aspect, since a plurality of first surface fasteners are attached to both the outdoor surface and the indoor surface of the wall sheet, the corresponding first surface fasteners can be connected to close the access part regardless of whether the user is inside or outside.

[0018] In another aspect of the evacuation tent unit according to the present invention, when the user exits the tent and closes the access part, the first surface fasteners on the outdoor surface are connected to each other. It is characterized in that when the user closes the access part from the inside of the tent, the first surface fasteners on the indoor surface are connected to each other.

[0019] According to this aspect, regardless of whether the user is indoors or outdoors, the corresponding first - surface fasteners can be connected to close the entrance / exit.

[0020] In another aspect of the evacuation tent unit according to the present invention, the ceiling framework is in the shape of a rectangular frame in plan view, a ladder - shaped reinforcing girder is attached inside the ceiling framework, and the chamber is placed on the reinforcing girder. The reinforcing girder is installed at a position close to one of the shaft members parallel to the longitudinal direction of the reinforcing girder among the plurality of shaft members constituting the ceiling framework.

[0021] According to this aspect, by placing the chamber on the ladder - shaped reinforcing girder inside the ceiling framework, the chamber can be stably held. Also, since the reinforcing girder is installed at a position close to one of the shaft members parallel to the longitudinal direction of the reinforcing girder among the plurality of shaft members constituting the ceiling framework, in other words, since the reinforcing girder is not at the center of the ceiling framework but near one of the end sides, the user can press the switching button for air supply and exhaust provided in the chamber without any hindrance.

[0022] In another aspect of the evacuation tent unit according to the present invention, the wall sheet is a blind sheet that cannot be visually recognized from the outside. The ceiling sheet is characterized by having at least a light - transmissive transparent or translucent top - edge sheet.

[0023] According to this aspect, since the wall sheet is a blind sheet that cannot be visually recognized from the outside, the privacy inside the tent can be ensured. Also, since the ceiling sheet has at least a light - transmissive transparent or translucent top - edge sheet, light such as ceiling lighting in the evacuation facility can be taken into the interior of the tent through the ceiling sheet.

[0024] In another aspect of the evacuation tent unit according to the present invention, the ceiling sheet further includes an endless upper light-shielding sheet that hangs downward from the edge of the top sheet. When the ceiling sheet is covered over the upper part of the ceiling framework and the wall framework, the upper light-shielding sheet covers the upper part of the wall framework, so that the ceiling sheet is installed without lateral displacement.

[0025] According to this aspect, since the ceiling sheet further includes an endless upper light-shielding sheet in addition to the top sheet, when the ceiling sheet is covered over the ceiling framework from above, it can be smoothly installed without laterally displacing the ceiling sheet.

[0026] In another aspect of the evacuation tent unit according to the present invention, a light-impermeable ceiling interior sheet that covers at least a part of the interior surface of the ceiling sheet from the indoor side is attached to the interior surface of the ceiling sheet.

[0027] According to this aspect, by attaching the light-impermeable ceiling interior sheet to the interior surface of the light-permeable ceiling sheet at bedtime, it is possible to suppress the intake of light into the interior of the tent and the inhibition of sleep.

[0028] In another aspect of the evacuation tent unit according to the present invention, a chamber communicating with the outdoor branch air duct is installed in the ceiling of the evacuation tent. The top sheet includes a first opening and a second opening where the chamber is installed. When supplying air into the interior of the evacuation tent or when stopping the supply and exhaust, the second opening is closed by a light-permeable transparent or translucent closing sheet. When exhausting air from the interior of the evacuation tent, the second opening is closed by the breathable closing sheet.

[0029] According to this aspect, the top sheet has a second opening in addition to the first opening where the chamber is installed. When supplying air into the tent interior or stopping the supply and exhaust of air, the second opening is closed by a light-transmissive closing sheet, thereby achieving both the airtightness and light transmittance of the tent. On the other hand, when exhausting air from the tent interior, the second opening is closed by a breathable closing sheet, thereby eliminating the problem that the interior of the tent becomes an excessive negative pressure atmosphere due to the exhaust.

[0030] Also, in another aspect of the evacuation tent unit according to the present invention, the chamber is provided with a filter inside and a chamber fan on the wall surface. The chamber fan has an air supply assisting function of supplying the air supplied to the chamber by the outdoor air supply fan into the interior of the evacuation tent, and an exhaust function of exhausting the air in the interior of the evacuation tent to the outside.

[0031] According to this aspect, since the chamber is provided with a chamber fan, the air supplied to the chamber can be sufficiently supplied into the tent interior, and the exhaust of the air from the tent interior can be effectively performed.

[0032] Also, in another aspect of the evacuation tent unit according to the present invention, a bed is accommodated inside the evacuation tent. The bed is composed of a bed base formed by arranging a plurality of boxes side by side, and a mattress placed on the bed base. The box is a repurposed box that is applied when each component of the evacuation tent is packed and transported.

[0033] According to this aspect, since the bed base constituting the bed is a repurposed box that is applied when each component of the tent is packed and transported, there is no need to secure a separate space for storing the box in the evacuation facility. Here, as the box, a cardboard box that is relatively rigid and generally applied as a packing box is preferable.

[0034] Also, in another aspect of the evacuation tent unit according to the present invention, an air-conditioned pillow is placed on the mattress, the air-conditioned pillow and the chamber communicate with each other through an indoor air duct, and air supplied to the chamber is supplied to the air-conditioned pillow through the indoor air duct.

[0035] According to this aspect, by supplying the air supplied to the chamber to the air-conditioned pillow through the indoor air duct, for example, cool air with appropriate temperature and air volume can be supplied to the user's head, and a comfortable sleeping environment can be formed.

[0036] Also, in another aspect of the evacuation tent unit according to the present invention, a connecting cylinder protruding downward is provided at the edge of the lower panel provided in the chamber, the air-conditioned pillow and the connecting cylinder communicate with each other through an indoor air duct, and a duct fan for assisting the supply of air to the air-conditioned pillow is interposed in the middle of the indoor air duct.

[0037] According to this aspect, since a connecting cylinder protruding downward is provided at the edge of the lower panel provided in the chamber, the indoor air duct can be smoothly attached to the chamber. Also, since a duct fan for assisting the supply of air to the air-conditioned pillow is interposed in the middle of the indoor air duct, sufficient air supply to the air-conditioned pillow can be achieved.

[0038] Also, in another aspect of the evacuation tent unit according to the present invention, the air-conditioned pillow is rectangular in plan view, On the upper surface of the air-conditioning pillow where the back of the user's head is placed, a strip-shaped blowing portion having a plurality of blowing holes for blowing air is provided. In a plan view, the blowing portion is disposed above the center of the longitudinal length of the air-conditioning pillow, and the lateral length of the blowing portion is in the range of 1.8 times to 2.2 times that of the back of the head.

[0039] According to this aspect, since the strip-shaped blowing portion provided in the air-conditioning pillow is disposed above the center of the longitudinal length of the air-conditioning pillow, the upper part of the back of the user's head can be cooled with air (cold air), and sleep can be promoted. Further, since the lateral length of the blowing portion is in the range of 1.8 times to 2.2 times that of the back of the user's head, even when the user lies on the side by turning over on the air-conditioning pillow, the head can be positioned above the blowing portion.

[0040] Also, one aspect of the evacuation tent according to the present invention is A plurality of evacuation tents constituting an evacuation tent unit, Outdoor branch air ducts communicate with each of the evacuation tents, respectively, and each outdoor branch air duct communicates with a common main air duct, and the main air duct communicates with an outdoor air supply fan.

[0041] According to this aspect, since air is supplied from a common outdoor air supply fan to a plurality of evacuation tents, the occupied area of the outdoor air supply fan can be suppressed, which can contribute to the suppression of the occupied area of the entire evacuation tent unit. In addition, the evacuation tent may be in a form in which a single evacuation tent is installed in an evacuation facility in addition to the form in which a plurality of evacuation tents exist. In this form, one evacuation tent and one outdoor air supply fan are connected via a main air duct and an outdoor branch air duct.

[0042] Also, one aspect of the evacuation shelter building according to the present invention is An evacuation shelter building including a plurality of evacuation tents, Outdoor branch air ducts communicate with each evacuation tent respectively, each outdoor branch air duct communicates with a common main air duct, and the main air duct communicates with an outdoor air supply fan.

[0043] According to this aspect, by supplying air from a common outdoor air supply fan to a plurality of evacuation tents, the occupied area of the outdoor air supply fan can be suppressed, and an evacuation shelter building with the occupied area of the entire evacuation tent unit suppressed can be formed. Therefore, the space other than the occupied space of the evacuation tent unit can be widened as much as possible, and it becomes possible to accommodate as many evacuees as possible.

Effect of the Invention

[0044] According to the evacuation tent unit, evacuation tent, and evacuation shelter building of the present invention, the occupied area in the evacuation facility can be suppressed as much as possible.

Embodiments for Carrying Out the Invention

[0046] Hereinafter, an example of a tent unit for a shelter, a tent for a shelter, and a shelter building according to an embodiment will be described with reference to the accompanying drawings. In the present specification and the drawings, substantially the same constituent elements may be denoted by the same reference numerals, and redundant descriptions may be omitted.

[0047] [Shelter Building and Tent Unit for a Shelter According to an Embodiment] First, with reference to FIGS. 1 and 2, an example of a shelter building and a tent unit for a shelter according to an embodiment will be described. Here, FIG. 1 is a perspective view showing the inside of an example of a shelter building according to an embodiment and the appearance of an example of a tent unit for a shelter and a tent for a shelter. Further, FIG. 2 is a front view of an example of a tent unit for a shelter and a tent for a shelter as seen along the longitudinal direction of the main air duct.

[0048] The shelter building 100 is an existing gymnasium, community hall, hall, etc., which is designated as an evacuation facility for a certain period during a disaster and enables the evacuation of a relatively large number of evacuees.

[0049] Inside the shelter building 100, in addition to ensuring a floor space (not shown) for healthy evacuees, a plurality (six in the illustrated example) of tents 70 for a shelter for accommodating infectious disease patients and the like are installed.

[0050] Each evacuation tent 70 has a unique outdoor branch air duct 83 communicating therewith. Each outdoor branch air duct 83 communicates with a common main air duct 82, and the main air duct 82 communicates with an outdoor air supply fan 81, thereby forming an evacuation tent unit 90. In this way, the evacuation building 100 is a building in which an existing gymnasium or the like is used as an evacuation facility and the evacuation tent unit 90 is installed inside thereof.

[0051] In the illustrated example, a transformer 84 (here, a step-up transformer) is electrically connected to the outdoor air supply fan 81, and a voltage boosted from, for example, 100V to 200V by the transformer 84 is applied to the outdoor air supply fan 81. The outdoor air supply fan 81 in the illustrated example has two air supply systems, and one end of a main air duct 82 unique to each air supply system is attached thereto.

[0052] Three outdoor branch air ducts 83 branch from each main air duct 82, and one end of a corresponding outdoor branch air duct 83 is attached to a chamber 31 above the ceiling of the three-room evacuation tent 70.

[0053] The air supplied from the outdoor air supply fan 81 flows through the two main air ducts 82 in the Z1 direction, flows through each outdoor branch air duct 83 in the Z2 direction, is supplied to the chamber 31, and is supplied into the interior of the evacuation tent 70 through the chamber 31. Here, the number of evacuation tents 70 installed in the evacuation building 100 may be other than that in the illustrated example, and a form may be adopted in which one main air duct 82 extends from the outdoor air supply fan 81 and a plurality of outdoor branch air ducts 83 branch from the one main air duct 82.

[0054] The outdoor air supply fan 81 desirably has a heating and cooling function of generating cold air and warm air as supply air, similar to a normal air conditioner (air conditioner), and can be switched to cold air or warm air at a desired temperature according to the temperature and humidity inside the evacuation building 100 such as season and day and night. Further, the outdoor air supply fan 81 may incorporate an outdoor unit for exhausting heat generated, for example, when generating cold air inside thereof.

[0055] The outdoor air supply fan 81 incorporates a control unit (not shown) and has a CPU (Central Processing Unit), NVRAM (Non-Volatile RAM), RAM (Random Access Memory), ROM (Read Only Memory), HDD (Hard Disc Drive), etc. (none of which are shown), and each part is connected via a bus so as to be able to transmit and receive data. Various programs and data used by the programs are stored in the ROM. The RAM is used as a storage area for loading programs and a work area for the loaded programs. The CPU realizes various functions by processing the programs loaded into the RAM. Programs and various data used by the programs are stored in the HDD. Various setting information, etc. is stored in the NVRAM.

[0056] For example, based on measurement information from a temperature sensor, a humidity sensor (both not shown), etc., it may be configured to generate air at a temperature suitable for air supply and supply the air to each evacuation tent 70.

[0057] Also, an electrician's drum 85 is electrically connected to the transformer 84, and an electrical wiring 86 extending from the electrician's drum 85 extends into the interior of each evacuation tent 70, and a power outlet attached to the end of the electrical wiring 86 is installed indoors.

[0058] [Evacuation Tent According to the Embodiment] Next, with reference to FIGS. 3 to 9, an example of an evacuation tent according to an embodiment will be described. Here, FIG. 3 is an exploded perspective view of an example of an evacuation tent according to an embodiment, and FIG. 4 is an exploded perspective view of an example of a chamber, an indoor air duct, and an air-conditioning pillow. Further, FIG. 5 is a perspective view of the ceiling as seen from the indoor side of the evacuation tent, showing a state in which the entire surface of the top sheet is light-transmissive, and FIG. 6 is a view corresponding to FIG. 5, showing a state in which a ceiling indoor sheet is attached to a part of the ceiling sheet. Furthermore, FIG. 7 is a perspective view showing a state in which air is being supplied into the evacuation tent, FIG. 8 is a perspective view showing a state in which air is being exhausted from the evacuation tent, and FIG. 9 is a perspective view showing an example of a bed and an air-conditioning pillow arranged in the evacuation tent.

[0059] The evacuation tent 70 includes a floor framework 5 composed of a plurality of shaft members 1, a ceiling framework 6 composed of a plurality of shaft members 1, a shaft member 1 constituting the floor framework 5 and the ceiling framework 6, and a wall framework 7 composed of vertical bars 2 (an example of a shaft member), and has a cubic or rectangular parallelepiped outer shape. The shaft member 1 and the vertical bar 2 are formed of a metal square pipe or the like having a relatively small cross-sectional dimension (10 mm to 15 mm × 10 mm to 15 mm), and by applying an aluminum square pipe, it becomes lightweight and has good transportability and assemblability.

[0060] Each shaft member 1 exists independently, and each framework may be formed by assembling the ends of the shaft members 1 via a connecting fitting (not shown). Alternatively, three shaft members 1 constituting the floor framework 5 may be connected to each other via a rotating fitting such as a hinge or a slide hinge (not shown), and the three shaft members 1 may be expanded in a U-shape in plan view via the rotating fitting. Regarding the ceiling framework 6 as well, after expanding three shaft members 1 connected to each other via a rotating fitting in a U-shape in plan view, by disposing another shaft member 1 at the opening of the U-shape, a square frame-shaped ceiling framework 6 as shown in the illustrated example can be formed.

[0061] At the lower end of each corner of the bed frame 5, casters 1a with stoppers are attached, enabling the evacuation tent 70 to be quickly moved to a desired position on the floor surface and installed immovably at the desired position.

[0062] Inside the ceiling frame 6 in the shape of a rectangular frame in plan view, a ladder-shaped reinforcing girder 8 is attached. Here, "rectangle" includes a square and a rectangle, and as an example of the planar dimensions of the ceiling frame 6, a square of 2m × 2m can be cited.

[0063] The reinforcing girder 8 has two longitudinal bars 8a and a plurality (four in the illustrated example) of transverse bars 8b connecting the two longitudinal bars 8a. The longitudinal bars 8a and the transverse bars 8b are formed of an aluminum material with a small cross-section, such as a square pipe, similar to the shaft member 1.

[0064] Also, as shown in FIG. 3, the reinforcing girder 8 is installed at a position close to one of the four shaft members 1 that make up the ceiling frame 6 and parallel to the longitudinal direction of the reinforcing girder 8. The reinforcing girder 8 is a girder on which the chamber 31 is placed, and various switches 36 shown in FIG. 4 are provided in the chamber 31. Since the reinforcing girder 8 is installed at a position close to one shaft member 1, and thus the chamber 31 exists near one side of the ceiling frame 6, users of the tent 70 and the like can operate the switch 36 from the outside of the tent 70 (for example, if the chamber 31 is in the center of the ceiling frame 6, the user cannot reach the switch 36).

[0065] By covering the ceiling sheet 13 from above the ceiling frame 6 in the Y1 direction, the ceiling sheet 13 covers the upper part of the ceiling frame 6 and the wall frame 7. The ceiling sheet 13 has a rectangular-shaped light-transmissive transparent or translucent top edge sheet 11 in plan view and an endless upper light-blocking sheet 12 hanging downward from the edge of the top edge sheet 11. Here, the light-transmissive top edge sheet 11 is formed of a transparent or translucent resin sheet, and a plurality of string members may be embedded in the sheet to increase the tensile strength of the sheet.

[0066] Since the ceiling sheet 13 includes the light-transmissive top sheet 11, it becomes possible to take in the light of the ceiling lighting of the evacuation shelter building 100 into the interior of the evacuation tent 70. That is, the evacuation tent 70 does not necessarily require a dedicated lighting fixture. Further, since the interior of the evacuation tent 70 cannot be visually recognized from the outside through the top sheet 11, the privacy of the users inside is ensured while the top sheet 11 is transparent or translucent.

[0067] On the other hand, since the upper light-shielding sheet 12 is literally a light-shielding sheet, visual recognition of the interior from the outside of the evacuation tent 70 through the upper light-shielding sheet 12 is suppressed. Further, when the ceiling sheet 13 is covered from above the ceiling framework 6, the four corner portions of the upper light-shielding sheet 12 having a rectangular frame shape in plan view are respectively covered along the four vertical bars 2 constituting the wall framework 7, so that the ceiling sheet 13 can be smoothly installed without shifting the ceiling sheet 13 in the lateral direction.

[0068] An endless surface fastener 18 is attached along the entire circumference of the upper light-shielding sheet 12 below the outdoor surface of the upper light-shielding sheet 12. This endless surface fastener 18 may be in a form that is continuously band-shaped or in a form that is intermittently continuous with a gap in the middle.

[0069] In the top sheet 11, a first opening 14 and a second opening 15 that are rectangular in plan view are provided at positions corresponding to the reinforcing bars 8 with a space therebetween.

[0070] The first opening 14 is an opening into which a chamber 31 having a rectangular parallelepiped shape or a cubic shape is loosely fitted in the Y3 direction. An endless sealing material 16 is attached around the first opening 14 on the upper surface of the top sheet 11. This sealing material 16 is formed of a resin such as rubber or a surface fastener such as Magic Tape (registered trademark).

[0071] On each of the four sides of the chamber 31, a locking flange 31a protrudes. By placing each locking flange 31a on the sealing material 16, a sealing structure between the chamber 31 and the sealing material 16 is formed. Each locking flange 31a is supported by the longitudinal bar 8a and the transverse bar 8b of the reinforcing girder 8.

[0072] On the other hand, an endless hook-and-loop fastener 17 is attached around the second opening 15. The closing sheet 19, which is rectangular in plan view and closes the second opening 15, is provided with a separate hook-and-loop fastener 20 at a position corresponding to the hook-and-loop fastener 17 on its lower surface, and the closing sheet 19 is attached in the Y4 direction from above the second opening 15.

[0073] For the closing sheet 19, sheets of different materials are applied according to their functions. Specifically, as shown in FIG. 7, when air flowing in the Z2 direction through the outdoor branch air duct 83 is supplied into the tent 70 for evacuation in the Z3 direction through the chamber 31, or when neither supply nor exhaust is performed, a closing sheet 19A formed of a light-transmitting transparent or translucent resin sheet or the like, similar to the top sheet 11, is applied.

[0074] On the other hand, as shown in FIG. 8, when exhausting in the Z6 direction from the inside of the tent 70 for evacuation through the chamber 31, a breathable closing sheet 19B is applied. By taking in outside air in the Z7 direction into the room through the breathable closing sheet 19B, an excessive negative pressure atmosphere inside the room during exhaust can be eliminated. Here, the closing sheet 19B is preferably made of a material with low air permeability to eliminate the excessive negative pressure atmosphere inside the room while ensuring the exhaust performance by the chamber fan 34 (see FIG. 4). As an example, non-woven fabric or the like can be mentioned.

[0075] Returning to FIG. 3, the wall frame 7 is covered with a wall sheet 21. The wall sheet 21 is provided with an access slit 23 that forms an access portion, and an endless surface fastener 22 is attached to the entire circumference of the wall sheet 21 on the upper indoor surface. This surface fastener 22 may also be in a form that is continuously band-shaped, similar to the surface fastener 18, or may be in a form that intermittently continues with a gap in the middle. The endless surface fastener 22 on the indoor surface of the wall sheet 21 is connected in the Y2 direction from the outside to the endless surface fastener 18 on the outdoor surface of the upper blind sheet 12, so that the ceiling sheet 13 and the wall sheet 21 are integrated.

[0076] In this way, by connecting the surface fasteners 18 and 22 to each other, the ceiling sheet 13 and the wall sheet 21 can be easily connected only by bonding the two. For example, if a normal fastener is applied instead of the surface fastener, it takes time to operate the fastener and it takes time to connect the ceiling sheet and the wall sheet.

[0077] Here, the wall sheet 21 is a blind sheet that cannot be seen into the room from the outside. Also, from the viewpoint of the attachability to the upper blind sheet 12, the wall sheet 21 is divided into two divided sheets, and it is preferable to attach them to the upper blind sheet 12 one by one.

[0078] A plurality of surface fasteners 24 (an example of a first surface fastener) are attached to the left and right of the vicinity of the access slit 23 in the wall sheet 21, and a separate surface fastener 25 (an example of a second surface fastener) is attached to a position away from the end of the access slit 23 (the side surface different from the side surface where the access slit 23 is located in the illustrated example).

[0079] The corresponding hook-and-loop fasteners 24 on the left and right of the access slit 23 are connected in the Y6 direction, thereby closing the access part. More specifically, among the left and right of the access slit 23, in the vicinity of the access slit 23 on the outdoor surface of the front left wall sheet 21 in the illustrated example, a plurality of hook-and-loop fasteners 24a are attached in the direction along the access slit 23. On the other hand, in the vicinity of the access slit 23 on the indoor surface of the front right wall sheet 21, a plurality of hook-and-loop fasteners 24b are attached in the direction along the access slit 23.

[0080] When the user exits the evacuation tent 70 and closes the access part, by connecting the two hook-and-loop fasteners 24a and 24b in the Y6 direction, the user outside the tent 70 can easily close the access part.

[0081] On the other hand, in the vicinity of the access slit 23 on the outdoor surface of the front left wall sheet 21, a plurality of separate hook-and-loop fasteners 24c are attached so as to protrude laterally from the access slit 23. Incidentally, the hook-and-loop fastener 24c may be attached to the indoor surface of the front left wall sheet 21. On the other hand, at a position slightly separated from the access slit 23 on the indoor surface of the front right wall sheet 21, another separate hook-and-loop fastener 24d is attached.

[0082] When the user closes the access part from the inside of the evacuation tent 70, by connecting the two hook-and-loop fasteners 24c and 24d in the Y7 direction, the user inside the tent 70 can easily close the access part.

[0083] Also, when opening the access part, by connecting the lowermost hook-and-loop fasteners 24a and 24b near the access slit 23 of the wall sheet 21 in the Y5 direction to the hook-and-loop fastener 25 on the side surface different from the side surface where the access slit 23 is located, it becomes possible to open the access part as wide as possible.

[0084] By connecting the hook-and-loop fasteners 24 to each other or connecting the hook-and-loop fasteners 24 and 25, as described above, the opening and closing posture of the entrance / exit part can be easily maintained only by bonding the two together.

[0085] The ceiling sheet 13 is installed in the Y1 direction with respect to the ceiling framework 6 at the top end of the wall framework 7, the wall sheet 21 is connected to the ceiling sheet 13 in the Y2 direction, and further, the chamber 31 is installed so as to close the first opening 14 of the top end sheet 11, whereby the evacuation tent 70 is formed.

[0086] As shown in FIG. 4, the chamber 31 has a rectangular tube-shaped side wall, and a filter 32 is installed inside the chamber 31. Further, the locking flanges 31a described above are attached to the four side walls. Here, the filter 32 is formed of a high-performance filter such as, for example, a HEPA (High Efficiency Particulate Air Filter) filter. Further, by providing a pre-filter made of, for example, a coarse dust filter at the suction port and the blow-out port of the outdoor air supply fan 81, the filter 32 composed of a high-performance filter can be made to have a longer service life.

[0087] Further, by providing a known fragrance generator or fragrance agent inside the chamber 31, at the blow-out port or the suction port of the chamber 31, etc., air with a fragrance can be supplied into the interior of the tent 70, and the comfort in the interior can be improved.

[0088] Further, by providing a deodorant inside the chamber 31, etc., deodorized air can be supplied into the interior of the tent 70, and odors generated, for example, during a long-term evacuation life in the interior of the tent 70 can be deodorized.

[0089] Further, by providing a device that generates a bactericidal gas such as chlorine dioxide or hydrogen peroxide inside the chamber 31, etc., when the users of the tent 70 are replaced, the bactericidal gas can be supplied into the interior of the tent 70 to perform sterilization.

[0090] One of the four side walls of the chamber 31 is provided with an opening, and a hood mounting fitting 33 is attached to the outside of the side wall. Inside the hood mounting fitting 33, a chamber internal fan 34 is attached. A plurality of surface fasteners 35 are attached to the outer surface of the hood mounting fitting 33.

[0091] The hood mounting fitting 33 is configured such that the reduced-diameter cylindrical portion of a hood 37 having a large-diameter cylindrical portion and a reduced-diameter cylindrical portion is fitted therein. At the end of the reduced-diameter cylindrical portion, there is a joining flange 38, and a surface fastener 39 is attached to the surface of the joining flange 38. When the hood 37 is fitted into the hood mounting fitting 33 in the Y9 direction, the hood 37 is fixed to the hood mounting fitting 33 by connecting the two surface fasteners 35, 39. Incidentally, a separate surface fastener may also be attached to the inner surface of the reduced-diameter cylindrical portion of the hood 37.

[0092] A switch box having a plurality of switches 36 is attached to another one of the four side walls of the chamber 31. The switch 36 includes an air supply switch 36a that operates the chamber internal fan 34 to supply air into the room, an exhaust switch 36c that operates the chamber internal fan 34 to exhaust air to the outside, and a stop switch 36b that stops both the air supply and the exhaust.

[0093] As shown in FIG. 7, the chamber internal fan 34 has an air supply assisting function of supplying the air supplied into the chamber 31 in the Z2 direction by the outdoor air supply fan 81 into the tent 70 in the Z3 direction.

[0094] Furthermore, as shown in FIG. 8, the chamber internal fan 34 has an exhaust function of exhausting the air inside the tent 70 to the outside in the Z6 direction.

[0095] By manually pressing the air supply switch 36a and the exhaust switch 36c, the user can obtain the air supply function and the exhaust function of the chamber fan 34. As described above, when supplying air into the room, after closing the second opening 15 with the closing sheet 19A formed of a light-transmitting transparent or translucent resin sheet or the like, the air supply switch 36a is pressed. On the other hand, when exhausting air to the outside, after closing the second opening 15 with the breathable closing sheet 19B, the exhaust switch 36c is pressed.

[0096] A bottom plate 41 with a plurality of air blowing and suction holes 42 is attached to the bottom surface of the chamber 31. More specifically, bolt holes 31b are formed at the corner portions of the bottom surface (the outer periphery of the filter 32) of the chamber 31 having a rectangular shape in plan view, and bolt holes 41a are also formed at the corner portions of the bottom plate 41 having a rectangular shape in plan view.

[0097] The bottom plate 41 is transferred in the Y8 direction with respect to the bottom surface of the chamber 31, and bolts 44 are screwed into the corresponding bolt holes 41a and 31b, whereby the chamber 31 and the bottom plate 41 are attached. In actual attachment, the bottom surface of the chamber 31 is directed upward, and the bottom plate 41 is dropped from above.

[0098] A connection cylinder 43 protruding downward is provided at the edge of the bottom plate 41. One end of the indoor air duct 45 disposed indoors of the tent 70 is fitted into the connection cylinder 43 in the Y10 direction.

[0099] A hook-and-loop fastener 47 is attached around the connection cylinder 43, and a hook-and-loop fastener (not shown) is also attached inside one end of the indoor air duct 45. When the indoor air duct 45 is fitted into the connection cylinder 43 in the Y11 direction, the two hook-and-loop fasteners are connected to fix the indoor air duct 45 to the connection cylinder 43.

[0100] As shown in FIG. 5, a chamber 31 is placed on a reinforcing girder 8, and an indoor air duct 45 fixed to a connection cylinder 43 of a bottom face plate 41 hangs down from the ceiling and is fixed to a vertical member 2 constituting a wall framework 7 or a shaft member 1 constituting a floor framework 5 by a surface fastener (not shown) or the like. Incidentally, the surface fastener used here can be diverted from the surface fastener that was applied when packing electrical wiring 86 or the like, which is a component of an evacuation tent 70, together in a cardboard box for transportation.

[0101] The indoor air duct 45 is disposed along each shaft member 1 constituting the floor framework 5, and the other end thereof is inserted into a duct insertion portion 52 provided in an air-conditioning pillow 51 and fixed by a binding string 53 in the duct insertion portion 52.

[0102] As shown in FIG. 5, a plurality of surface fasteners 61 are attached above the indoor surface of the ceiling sheet 13. Here, the plurality of surface fasteners 61 may be attached to the ceiling framework 6. Since the ceiling sheet 13 is generally soft, when an optically opaque ceiling indoor sheet 62 is attached to the ceiling sheet 13, the ceiling sheet 13 may move. On the other hand, since the ceiling framework 6 is rigid, when the ceiling indoor sheet 62 is attached to the ceiling framework 6, the ceiling framework 6 does not move, and the attachability of the ceiling indoor sheet 62 becomes even better. Also, when the ceiling indoor sheet 62 is attached to the ceiling framework 6, there is no fear that the ceiling framework 6 will bend. Incidentally, when the user is awake, the light of the ceiling lighting of the evacuation shelter building 100 is taken into the room through the light-transmissive top sheet 11.

[0103] On the other hand, when the user goes to bed, as shown in FIG. 6, an optically opaque ceiling indoor sheet 62 that covers at least a part of the indoor surface of the ceiling sheet 13 from the indoor side is installed. The ceiling indoor sheet 62 is provided with surface fasteners 63 on its upper surface, and by connecting the plurality of surface fasteners 63 provided in the ceiling indoor sheet 62 to the plurality of surface fasteners 61 provided in the ceiling sheet 13, the ceiling indoor sheet 62 is fixed to at least a part of the indoor surface of the ceiling sheet 13.

[0104] By installing the light-impermeable ceiling interior sheet 62 at bedtime, the inhibition of sleep due to lighting is suppressed. Further, as shown in the illustrated example, by applying the ceiling interior sheet 62 with an area that does not inhibit sleep, the installation of the ceiling interior sheet 62 becomes easier. Here, the planar dimensions of the ceiling interior sheet 62 can be set to about 1 / 3 to 1 / 2 of the planar dimensions of the top edge sheet 11. However, a ceiling interior sheet that covers the entire area of the top edge sheet 11 may also be applied.

[0105] Returning to FIG. 4, a duct fan 46 for assisting the supply of air to the air-conditioning pillow 51 is interposed at an intermediate position of the indoor air duct 45. As shown in FIG. 4, the air taken into the chamber 31 by the chamber fan 34 is supplied into the room through a number of air blowing and suction holes 42 provided in the bottom panel 41, and is also supplied to the air-conditioning pillow 51 through the indoor air duct 45 attached to the connecting cylinder 43. At this time, since the pressure loss in the process of supplying air to the air-conditioning pillow 51 through the indoor air duct 45 is relatively large compared to the air blowing and suction holes 42, it becomes difficult to achieve sufficient air supply to the indoor air duct 45.

[0106] Therefore, by interposing the duct fan 46 in the middle of the indoor air duct 45 and operating the duct fan 46 to assist the air supply, sufficient air supply to the air-conditioning pillow 51 becomes possible.

[0107] As shown in FIG. 9, a bed 58 is accommodated inside the tent 70. The bed 58 includes a bed base 56 formed by arranging a plurality of boxes 55 side by side, and a mattress 57 placed on the bed base 56. The air-conditioning pillow 51 is placed on the mattress 57.

[0108] It is preferable that the box 55 is a repurposed box applied when accommodating and transporting each component of the tent 70. Further, the box 55 preferably has relatively high rigidity and is a corrugated box generally applied as a packing box.

[0109] As shown in Fig. 9, the air flowing in the Z4 direction through the indoor air duct is blown upward in the Z5 direction through the blowing portion 54 provided in the air-conditioning pillow 51.

[0110] The air-conditioning pillow 51 is formed by housing a cloth mesh bag containing a cylindrical resin material (straw material) in a pillowcase, and has a strength and breathability capable of supporting the head. The straw material is cylindrical with a diameter (outer shape) of 5 mm, a length of 7 mm, and a thickness of 0.1 mm, and is formed of, for example, polypropylene. On the other hand, in the cloth mesh bag, by setting the opening ratio of the mesh to 95% and making the opening size large enough so that the cylindrical straw material does not pass through, the breathability becomes even better. And on the upper surface of the pillowcase, a strip-shaped blowing portion 54 provided with a plurality of blowing holes for blowing out air is provided.

[0111] Returning to Fig. 4, in the plan view of the air-conditioning pillow 51, when the longitudinal length of the air-conditioning pillow 51 is t1 and the lateral length is t2, the strip-shaped blowing portion 54 is disposed above the center (t1 / 2) of the longitudinal length of the air-conditioning pillow 51. Also, the lateral length t3 of the blowing portion 54 is preferably in the range of 1 to 2.2 times the circumference of the back of the user's head. Further, the lateral length t3 of the blowing portion 54 is preferably in the range of 0.6 to 0.8 times the lateral length t2 of the air-conditioning pillow 51.

[0112] If the lateral length t3 of the blowing portion 54 is 1 time or more the circumference of the back of the user's head, the back of the head can be cooled even when the user lies on their back. Also, if the lateral length t3 is 1.8 times or more the circumference of the back of the user's head, the head (especially the side head) can be positioned on the blowing portion 54 even when the user turns over from the lying-on-back state to the side-lying position.

[0113] If the lateral length t3 of the blowing portion 54 is too long, there will be many unnecessary areas that do not cool the user's head, and it becomes difficult to generate a sufficient wind speed (enough to promote sleep by cooling), so the lateral length t3 of the blowing portion 54 is desirably 2.2 times or less the circumference of the back of the head.

[0114] Here, according to the Japanese Head Dimension Database 2001, it is known that the head width of a person is approximately 140 mm to 170 mm. Incidentally, the above database can be referred to at the following URL: "https: / / www.airc.aist.go.jp / dhrt / head / index.html".

[0115] When the horizontal length t3 of the blowing part 54 is set to 1 to 2.2 times the above numerical range, the horizontal length t3 becomes about 140 mm to 380 mm.

[0116] Also, when the horizontal length t3 of the blowing part 54 is set to 1.8 to 2.2 times the above numerical range, the horizontal length t3 becomes about 250 mm to 380 mm.

[0117] When the average head width is 155 mm, if the horizontal length t3 of the blowing part 54 is set to 1.8 to 2.2 times this value, the horizontal length t3 becomes about 280 mm to 340 mm.

[0118] Also, as for the wind speed of the air blown out from the blowing part 54, 0.33 m / s is a comfortable wind speed.

[0119] In this way, since the blowing part 54 is disposed above the center (t1 / 2) of the longitudinal length of the air-conditioning pillow 51, the upper part of the back of the user's head can be cooled with air (cool air), and sleep can be promoted. Incidentally, since cooling the lower part of the back of the head (the part below the ears) wakes up the brain and inhibits sleep, the set position of the blowing part 54 is preferably the position shown in the illustrated example.

[0120] As an example of the air-conditioning pillow 51, there is an air-conditioning pillow in which t1 is 340 mm, t2 is 500 mm, the horizontal length t3 of the blowing part 54 is 140 mm to 380 mm, and the length from the lower side of the air-conditioning pillow 51 to the lower side of the blowing part 54 is 180 mm.

[0121] FIG. 10 is a plan view showing an example of a state in which the constituent members of the evacuation tent are packed in a plurality of boxes.

[0122] A plurality of cardboard boxes that are repurposed as the bed base 56 are packed with various components of the evacuation tent and transported to the evacuation facility. After taking out the various components from the cardboard boxes transported to the evacuation facility, assembling the evacuation tent 70 and installing it at a predetermined position, the cardboard boxes remaining after the packaged items are taken out are repurposed as the bed base 56 to form the bed 58. Also, the hook-and-loop fastener around which the electrical wiring 86 etc. is wound is repurposed as a fastener for arranging and fixing in the tent interior of the indoor air duct 45. Although not shown, a plurality of plates for reinforcing the cardboard box when using the cardboard box as the bed base 56 may also be packed in the cardboard box and transported.

[0123] According to the evacuation tent unit 90 that constitutes the evacuation shelter building 100 described above, while securing a plurality of evacuation tents 70, it is possible to suppress as much as possible the occupied area of the evacuation tent unit 90 in the evacuation shelter building 100. Therefore, it becomes possible to accommodate as many healthy evacuees as possible inside the evacuation shelter building 100 while securing a plurality of evacuation tents 70 in which infectious disease patients etc. are accommodated within the limited space in the evacuation shelter building 100.

[0124] In addition, other embodiments in which other components are combined etc. may be used for the configurations etc. listed in the above embodiments, and the present invention is not limited to the configurations shown here at all. Regarding this point, it is possible to make changes without departing from the gist of the present invention, and it can be appropriately determined according to the application form.
