Description

Technical Field

[0001] The present invention relates to a shelter.

Background Art

[0002] Conventionally, various shelters prepared for purposes such as disaster prevention have been proposed. For example, in Patent Document 1 below, a radiation shielding structure using high-functional ceramic concrete for the outer wall material and inner wall material of various buildings has been proposed. This radiation shielding structure is constructed as a building and is a robust structure that can be installed outdoors.

[0003] Also, in Patent Document 2 below, a shelter constructed by installing a metal framework such as columns and beams inside a building has been proposed. This shelter is a structure that can absorb impacts by the framework when heavy objects fall from above during an earthquake or the like by constructing a frame structure inside the building.

[0004] By the way, according to a survey by the Japan Nuclear Shelter Association, the penetration rate of nuclear shelters in Japan is extremely low compared to overseas, with the penetration rate of nuclear shelters per person being 0.02% (Switzerland 100%, Israel 100%, the United States 82%, the United Kingdom 67%). Also, even if a person has an underground shelter, it is extremely difficult to escape into the shelter within a few minutes after a missile alarm such as J-Alert sounds, or to guide the elderly, those requiring care, and the majority of infants into the shelter without confusion.

[0005] In addition, due to the improvement in missile arrival speed in recent years, there is a possibility that there is no evacuation grace period at all. Underground concrete nuclear shelters and above-ground steel plate nuclear shelters, including at night, are completely defenseless against attacks that cannot be predicted in advance, and considering the travel time, it is highly likely that evacuation cannot be achieved at the time of missile landing.

[0006] Furthermore, in addition to nuclear attacks, threats from chemical weapons (sarin, VX gas, toxic gases, etc.) and biological weapons (anthrax, etc.) are also increasing, and there is a need for shelters that can be used as evacuation spaces in emergencies to protect the human body from these weapons as well. [Prior art documents] [Patent Documents]

[0007] [Patent Document 1] Japanese Patent Publication No. 2013-195416 [Patent Document 2] Japanese Patent Publication No. 2005-139612 [Overview of the project] [Problems that the invention aims to solve]

[0008] However, since it is extremely difficult to create a sealed space and a positive pressure environment within existing building structures, there is a desire to install shelters either outside or inside the building structures. However, conventional shelters, whether installed outside or inside the building structure, require the installation of columns and beams of appropriate size and sufficient strength, which can be cumbersome to handle, and their weight can easily increase, sometimes requiring reinforcement of the existing building structure, making them difficult to construct. In addition, since most Japanese people live in urban areas, there is no longer enough land or space to build shelters above or below ground. Furthermore, the only way to construct underground shelters is to demolish and rebuild existing buildings, which incurs high costs and makes installation difficult, thus hindering their widespread adoption.

[0009] Therefore, the object of the present invention is to provide a shelter that can be easily constructed within an existing building structure and that can ensure sufficient strength. [Means for solving the problem]

[0010] To solve the above problems, the shelter of the present invention is a shelter in which a plurality of wall sections are formed by connecting a plurality of wall segments, and the plurality of wall sections are connected to each other via a plurality of edge segments, wherein the wall segments have a flat wall panel section and a wall rising piece that is connected to the entire periphery of the wall panel section and erected on one side, and adjacent wall segments are connected by joining the wall rising pieces facing each other, adjacent edge segments are connected to each other and the wall sections are connected by joining the wall rising pieces of the wall segments located at the ends of the wall sections to the edge segments, thereby bending and connecting the wall sections, and the wall rising pieces of the plurality of wall segments constituting each wall section are arranged and arranged so as to be continuous in a striped pattern without bending.

[0011] With this type of shelter, the shelter can be constructed by connecting numerous small, divided wall segments and edge segments, making it possible to easily construct a shelter within an existing building structure, regardless of its size. Furthermore, since each wall segment has a wall-mounted piece attached to one side, connected to the entire periphery of the wall panel, the weight can be reduced while ensuring the strength of each wall segment. Moreover, since adjacent wall segments are connected by joining their wall-mounted pieces facing each other, the overall strength of each wall section can also be ensured while keeping the weight down. In addition, by joining the wall-mounted pieces of the wall segments located at the ends of the wall sections to the edge segments, the wall sections are connected and integrated, thus ensuring the strength of the three-dimensional structure formed by the connection of multiple wall sections. Furthermore, by arranging the vertical wall sections of the multiple wall segments that make up each wall section in a continuous, linear fashion without bending, these linearly continuous sections can be used as structural members such as columns, beams, girders, and joists of the shelter, thereby improving the overall strength of the shelter. As a result, it becomes possible to provide shelters that can be easily constructed within existing building structures while ensuring sufficient strength, and it also becomes possible to create a positive pressure environment inside the shelter.

[0012] In the shelter of the present invention, the edge segment has an edge panel portion having a shape in which a plurality of flat plate shapes are bent and connected, and an edge rising piece connected to the entire periphery of the edge panel portion and erected on one side, wherein adjacent edge segments are connected by joining the edge rising pieces facing each other, and adjacent wall segments and edge segments are connected by joining the wall rising pieces and edge rising pieces facing each other.

[0013] In this way, the edge panel portions of numerous edge segments have the same flat plate shape as the wall panel portions of wall segments, which is bent and connected, making it easy to geometrically arrange numerous wall segments and numerous edge segments adjacent to each other. Furthermore, since each edge segment has an edge riser attached to one side, connected to the entire perimeter of the edge panel, the weight can be reduced while ensuring the strength of each edge segment. In addition, since adjacent edge segments are connected by joining their edge risers facing each other, the overall strength of the edge can be ensured while keeping the weight down. Moreover, since adjacent edge segments and wall segments are connected by joining their edge risers and wall risers facing each other, the strength between the wall and the edge can also be ensured. As a result, it is easier to construct a shelter and easier to ensure its strength.

[0014] The shelter of the present invention is characterized in that each segment is provided with a plurality of joints for each of the rising pieces. In this way, adjacent segments are joined at multiple joints, thereby improving the strength of the connecting structure between segments. Moreover, if the multiple joints of each rising piece are at the same pitch, it becomes easy to join any adjacent segments together, making it easier to construct a shelter.

[0015] In the shelter of the present invention, the flat plate shape of each panel portion has a square shape, a rectangular shape, or a shape combining a square shape and a rectangular shape, and the shelter according to claim 1 or 2 is characterized in that. By doing so, it becomes easy to arrange a large number of segments, so that it becomes easy to construct a shelter. In addition, various segments can be combined according to the installation location and installation situation, and it becomes possible to reduce costs and shorten the construction period. Moreover, there is no limitation on the size of each panel, and it is also possible to change the size according to the installation location and installation situation.

[0016] In the shelter of the present invention, each rising piece may be erected in a direction perpendicular to the flat plate shape of each panel portion. By doing so, it becomes easy to arrange the flat plate shapes of the panel portions of adjacent segments in the same plane, and it becomes easy to construct each wall portion.

[0017] In the shelter of the present invention, the edge segment may have an edge panel portion in which two of the flat plate shapes are bent and connected to each other in a perpendicular direction. In that case, the edge segment may further have an edge panel portion in which three of the flat plate shapes are bent and connected to each other in a perpendicular direction. By doing so, it becomes easy to construct a shelter having a substantially rectangular parallelepiped shape or a cube shape.

[0018] In the shelter of the present invention, a shielding material having a higher radiation shielding rate than the panel portion may be laminated on the front side or the back side of the panel portion. By doing so, a nuclear shelter can be easily constructed in an existing building structure.

Effect of the Invention

[0019] According to the present invention, it is possible to provide a shelter that can be easily constructed in an existing building structure and can ensure sufficient strength.

Embodiments for Carrying Out the Invention

[0021] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The shelter of this embodiment is installed indoors in an existing building structure and is arranged on the floor or floor slab of the building structure. FIG. 1 is a schematic diagram showing the structure of the shelter, and FIG. 2 is a configuration diagram showing a part of the structure of the shelter. First, as shown in Figure 1, the shelter 100 is formed in a hollow polyhedral shape, and is formed in a rectangular parallelepiped or cubic shape, comprising four side walls 10, a ceiling portion 20 that closes the top of the side walls 10, and a floor portion 30 that forms the floor of the shelter 100.

[0022] The side walls 10 are provided with doors 10a that serve as entrances and exits to the shelter. In addition, interior panels such as wall panels, ceiling panels, and floor panels are fitted to the side walls 10, ceiling 20, and bottom 30, respectively. Furthermore, various equipment suitable for the shelter 100's purpose, such as ventilation systems and toxic substance removal systems, can be installed.

[0023] The shelter 100 is constructed by connecting numerous and diverse segments, which are made of metals such as steel, stainless steel, and aluminum. As shown in Figure 2, the side walls 10 and the floor 30 are constructed by connecting multiple wall segments 11 to each other. In addition, to connect the side walls 10 and the floor 30, the wall segments 11 are first connected via two wall edge segments 12 that form the corners of the shelter, thereby continuously connecting the side walls 10 and the floor 30. Furthermore, the two wall edge segments 12 are continuously connected via three wall edge segments 13 that form the edges of the four corners of the floor 30 shown in Figure 2 of the shelter 100.

[0024] For the section of the side wall 10 where the door is installed, a door segment 14 is used that is lower in height than the other two wall edge segments 12. Figure 2 clearly illustrates the connection between the side wall 10 and the floor section 30, and since the configuration of the ceiling section 20 is similar, the description of the ceiling section 20 is omitted.

[0025] Next, we will explain the configuration of each segment with reference to Figures 3-10. Figure 3 is a perspective view showing the configuration of the wall segment, and Figure 4 is a cross-sectional view showing a cross-section of the wall segment. As shown in the figure, the wall segment 11 has a wall panel portion 11a and a wall rising piece 11b that is connected to the entire periphery of the wall panel portion 11a and erected on one side. The wall panel portion 11a has a square flat plate shape, and although the shape of the flat plate is not particularly limited, it has a size such as a thickness of 1 to 6 mm and a length of 20 to 40 mm on each side. The size of the wall panel 11a can be changed depending on the installation location and conditions.

[0026] The wall-mounted pieces 11b are provided on all four sides of the flat shape of the wall panel portion 11a, and are erected perpendicular to one side of the flat shape. Each wall-mounted piece 11b is formed in the shape of a strip of a certain width, and the width of all four wall-mounted pieces 11b is the same. Each edge of the wall panel 11a and each wall-mounted piece 11b are connected and integrated along their entire length. The wall-mounted piece 11b is not particularly limited, but for example, it has a thickness of 1 to 6 mm and a width of 10 to 30 mm. Furthermore, the wall rising pieces 11b are connected and integrated across their entire width, and each wall rising piece 11b has multiple through holes 11c, spaced at the same pitch and in the same number. Furthermore, the wall rising piece 11b of the wall segment 11 installed near the door 10a is used to support and fix a door frame (not shown) for installing the door 10a.

[0027] Note that the wall segment 11 is not necessarily limited to the configuration described above. For example, the shape of the wall panel 11a does not have to be square; it may be rectangular. Also, the shape of the wall rising edges 11b does not have to be the same width; they may have different widths. Furthermore, the number and pitch of the through holes 11c can be changed as appropriate, and the dimensions of each component can also be changed as appropriate.

[0028] Figure 5 is a perspective view showing the configuration of the two wall edge segments, Figure 6(a) is a front view showing the configuration of the two wall edge segments, and Figure 6(b) is a side view showing the configuration of the two wall edge segments. As shown in the figure, the two wall edge segments 12 are segments that are placed at corners connecting the side walls 10 of the shelter 100, corners connecting the side walls 10 to the ceiling 20, and corners connecting the side walls 10 to the floor 30.

[0029] The wall edge segment 12 has a wall edge panel section 12a formed by bending and connecting square flat plates, and a wall edge rising piece 12b erected on one side so as to connect to the entire periphery of the wall edge panel section 12a. The wall edge panel section 12a has a shape in which two identical flat plate shapes are bent perpendicular to each other and connected integrally. Each flat plate shape has the same square shape as the flat plate shape of the wall panel section 11a, and has the same thickness and size as the wall panel section 11a.

[0030] The two wall edge risers 12b are provided on the six sides that form the outer edge of the two wall edge panel section 12a, and each two wall edge riser 12b is erected perpendicular to one side of the adjacent flat plate shape. In this embodiment, the two wall edge risers 12b protrude inward toward the inside of the two wall edge panel section 12a, which has a shape formed by the bending of two flat plate shapes.

[0031] The two wall edge risers 12b are formed in a strip shape with the same constant width as the wall risers 11b, and the width of all six wall edge risers 12b is the same. The two wall edge risers 12b arranged along each of the two sides of the bent shape of the wall edge panel 12a are connected in a shape that is bent in the width direction in accordance with the bent shape. Each edge of the two-wall edge panel section 12a and each two-wall edge panel section 12b are integrally connected along their entire length. Furthermore, the two-wall edge rising pieces 12b provided on adjacent edges of the two-wall edge panel section 12a are integrally connected along their entire width. In addition, each two-wall edge rising piece 12b has multiple through holes 12c, the same number and at the same pitch.

[0032] However, the wall edge segment 12 is not necessarily limited to the configuration described above. For example, the two wall edge panels 12a may not be two square-shaped flat plates, but one may be square and the other rectangular, or both may be rectangular. Furthermore, the two wall edge risers 12b do not need to be strips of the same constant width, but may have different widths. Also, the number and pitch of the through holes 12c can be changed as appropriate, and the dimensions of each component can also be changed as appropriate.

[0033] Next, the configuration of the three wall edge segments will be explained with reference to Figures 7-8. Figure 7 is a perspective view showing the configuration of the three wall edge segments, Figure 8(a) is a front view showing the configuration of the three wall edge segments, and Figure 8(b) is a side view showing the configuration of the three wall edge segments. The three wall edge segments 13 are segments that make up the four corners of the floor 20 and the four corners of the ceiling 30 of the shelter 100, and are positioned at the four corners that connect the side walls 10 and the ceiling 20, and at the four corners that connect the side walls 10 and the floor 30. As shown in the figure, the three-wall edge segment 13 has a three-wall edge panel section 13a formed by bending and connecting three square-shaped flat plates, and a three-wall edge rising piece 13b erected on one side so as to connect to the entire periphery of the three-wall edge panel section 13a. The wall edge panel section 13a has a shape in which three flat plate shapes are integrally connected such that adjacent pairs of flat plate shapes are bent perpendicular to each other. Each flat plate shape has the same square shape as the flat plate shape of the wall panel section 11a, and has the same thickness and size.

[0034] The three wall edge risers 13b are provided on the six sides that form the outer edge of the three wall edge panel section 13a, which is formed by joining three flat plate shapes, and each three wall edge riser 13b is erected perpendicular to one side of the adjacent flat plate shape. In this embodiment, all three wall edge risers 13b protrude inward toward the inside of the three wall edge panel section 13a, which has a shape formed by the bending of three flat plate shapes.

[0035] Each of the three wall edge risers 13b is formed in a band shape with the same constant width as the wall riser 11b, and the width of all six sides of the three wall edge risers 13b is the same. The two three wall edge risers 13b that are positioned along the two sides of the bent shape between each pair of three wall edge panel sections 13a are connected in a shape that is bent in the width direction corresponding to the respective bent shape. Each edge of the wall edge panel section 13a and each wall edge rising piece 13b are integrally connected along their entire length. Furthermore, the wall edge rising pieces 13b provided on adjacent edges of the wall edge panel section 13a are integrally connected along their entire width. In addition, each wall edge rising piece 13b has multiple through holes 13c, the same number and at the same pitch.

[0036] Furthermore, the wall edge segment 13 is not necessarily limited to the configuration described above. In the wall edge panel section 13a, it is not necessary for it to be composed of three square-shaped flat plates; any one of them may have a different shape. For example, one or two may be square-shaped and the other one or two may be rectangular, or all three may be rectangular flat plates. Furthermore, the three wall edge risers 13b do not need to be the same width and may have different widths. Also, the number and pitch of the through holes 13c can be changed as appropriate, and the dimensions of each component can also be changed as appropriate.

[0037] Next, the configuration of the door segment will be explained with reference to Figures 9-10. Figure 9 is a perspective view showing the configuration of the door segment, Figure 10(a) is a front view showing the configuration of the door segment, and Figure 10(b) is a side view showing the configuration of the door segment. The door segment 14 is installed on the upper and lower parts of the door 10a to be installed on the side wall 10, and is a segment for connecting to the ceiling 20 and the floor 30.

[0038] The door segment 14 has a door panel section 14a formed by bending and connecting flat plate shapes, and a door rising piece 14b erected on one side so as to connect to the entire periphery of the door panel section 14a. The door panel section 14a has a shape in which two flat plates are bent perpendicular to each other and connected as a single unit. The panel section rising perpendicularly is lower in height compared to the two wall edge segments 12, and its height is appropriate to the size of the door to which it is installed. Furthermore, each flat plate shape has the same thickness and size as the wall panel portion 11a.

[0039] The door risers 14b are provided on the six outer edges of the door panel 14a, and each door riser 14b is erected perpendicular to one side of the adjacent flat plate shape. In this embodiment, the door risers 14b protrude inward from the door panel 14a, which is formed by the bending of two flat plate shapes. A portion of these door risers 14b is used to support and fix the lower part of the door frame of the door 10a to be installed. The door risers 14b serve as a sill, and the dimensions of these sill-like door risers 14b can be freely changed.

[0040] The door risers 14b are formed in a strip shape with the same constant width as the wall risers 11b, and the width of all six door risers 14b is the same. The two door risers 14b, which are positioned along each of the two sides of the bent shape of the door panel 14a, are connected in a shape that is bent in the width direction in accordance with the bent shape. Each edge of the door panel section 14a is integrally connected to each door panel section 14a along its entire length. Furthermore, the door risers 14b provided on adjacent edges of the door panel section 14a are integrally connected along their entire width. In addition, each door riser 14b has multiple through holes 14c, all spaced at the same pitch and in the same number.

[0041] Note that the door segment 14 is not necessarily limited to the configuration described above. For example, the door panel 14a is shaped to match the shape and size of the door 10a to be installed. Also, the door wall risers 14b do not need to be the same constant width, and may have different widths. Furthermore, the number and pitch of the through holes 14c can be changed as appropriate, and the dimensions of each component can also be changed as appropriate.

[0042] Next, the assembly method of the shelter 100 according to this embodiment will be described. The shelter 100 of this embodiment is constructed by connecting a large number of the above-mentioned wall segments 11, two wall edge segments 12, three wall edge segments 13, and door segments 14, as shown in Figures 1 and 2. The side walls 10, ceiling 20, and floor 30 are formed by arranging and connecting wall segments 11 vertically and horizontally in a two-dimensional direction. To connect wall segments 11 to each other, the wall upright pieces 11b of adjacent wall segments 11 are placed facing each other, the through holes 11c of each wall upright piece 11b are aligned, and the segments are joined by fastening them with bolts and nuts (not shown). Furthermore, at locations where a door 10a is to be installed on a part of the side wall 10, a space for installing the door 10a can be secured by connecting the door segment 14 to the wall segment 11.

[0043] When connecting the side walls 10 that make up each face of the shelter 100, the wall segments 11 positioned at the ends of the side walls 10 are connected via two wall edge segments 12. In this case, the wall rising piece 11b of the wall segment 11 and the two wall edge rising pieces 12b of the two wall edge segments 12 are placed facing each other, their respective through holes 11c and 12c are aligned, and then fastened with bolts and nuts to join them.

[0044] The same applies when connecting the side wall 10 to the ceiling 20 or when connecting the side wall 10 to the floor 30. Furthermore, three wall edge segments 13 are placed at each corner of the ceiling 20 and floor 30, and the upper or lower part of the three wall edge segments 13 is connected to the two wall edge segments 12 in the left-right direction. In this case, the three wall edge rising pieces 13b of the three wall edge segments 13 and the two wall edge rising pieces 12b of the two wall edge segments 12 are placed facing each other, and the through holes 12c, 13c are aligned and fastened with bolts and nuts to join them.

[0045] In a shelter 100 constructed by connecting multiple wall segments 11, two wall edge segments 12, three wall edge segments 13, and door segments 14 in this manner, the wall rising pieces 11b of multiple wall segments 11 are arranged vertically and horizontally so as to bend continuously across the entire wall. Similarly, the rising pieces 12b and 13b of the second wall edge segment 12 are arranged vertically and horizontally so as to bend continuously across the entire wall.

[0046] According to the shelter 100 described above, the shelter 100 can be constructed by first connecting numerous small, divided wall segments 11 and two wall edge segments 12 and three wall edge segments 13. Therefore, regardless of size, the shelter 100 can be easily constructed within an existing building structure.

[0047] Furthermore, since the wall segment 11 has a wall rising piece 11b erected on one side, connected to the entire periphery of the wall panel portion 11a, the weight can be reduced while ensuring the strength of each wall segment 11. Moreover, because adjacent wall segments 11 are connected by facing each other and connecting the wall rising pieces 11b, the overall strength of each side wall 10 can also be ensured while keeping the weight down. In addition, the wall rising pieces 11b of the wall segment 11 located at the end of the side wall 10 are joined to the second wall edge segment 12, and the second wall edge segment 12 and the third wall edge segment 13 are connected, integrating the side wall 10 and ensuring the strength of the three-dimensional structure.

[0048] Thus, the shelter 100 of this embodiment can be easily constructed by assembling each segment, and a shelter 100 can be easily constructed within an existing building structure and can ensure sufficient strength.

[0049] This embodiment can be modified as appropriate within the scope of the present invention. For example, when assembling the shelter 100, it is possible to use wall segments 11 and wall edge segments 12 as shown in Figures 11 and 12. Figure 11 shows another configuration of a wall segment, and Figure 12 shows another configuration of a two-wall edge segment.

[0050] Unlike the wall segment 11 shown in Figure 3, the wall segment 200 shown in Figure 11 has a wall panel portion 200a formed in a rectangular flat plate shape. Note that the wall rising piece 200b and through hole 200c have the same configuration as the wall segment 11 shown in Figure 3, so their explanation is omitted. The length of wall segment 200 is approximately the same as the length of two wall segments 11 placed side by side as shown in Figure 3, and one wall segment 200 can cover the equivalent length of two wall segments 11. Note that the dimensions of the wall segment 200 can be changed as needed; for example, it is possible to redesign it to match the length when two or more wall segments 11 are placed side by side.

[0051] Furthermore, as shown in Figure 12, it is possible to make one of the flat plate portions of the two-wall edge panel 300a rectangular, and it is also possible to make both flat plate portions rectangular (not shown).

[0052] As described above, by changing the dimensions of the panel portion, such as the wall segment 200 and the wall edge segment 300 shown in Figures 11 and 12, the number of parts required to assemble the shelter 100 can be reduced, thereby lowering costs. Furthermore, it becomes possible to use different types of segments or combine them depending on the installation location and conditions.

[0053] Furthermore, other materials may be laminated on the surface or back side of, for example, wall segment 11, wall edge segment 2 12, and wall edge segment 3 13. For example, it is possible to construct a nuclear shelter by laminating shielding materials with a high radiation shielding rate, and these shielding materials may include lead, tungsten, concrete, etc. Furthermore, by inserting materials that enhance the airtightness of the shelter 100, such as rubber gaskets, at the joints between the rising pieces 11b, 12b, and 13b of each segment, it is possible to prevent outside air from entering the shelter 100, making it possible to counter chemical weapons (sarin, VX gas, etc.) and biological weapons (anthrax, etc.).

[0054] Furthermore, although this embodiment describes how the side walls 10, ceiling 20, and floor 30 are all composed of segments 11, 12, 13, and 14, there is no particular need to limit this. For example, an existing floor surface or floor slab may be used as the floor 30, and only the side walls 10 and ceiling 20 may be composed of segments 11, 12, 13, and 14.

[0055] Furthermore, although the above embodiment describes an example where the shelter 100 is a cube or a rectangular parallelepiped, it may also be a polyhedron. In that case, for example, the bending shape of the rising pieces 12b and 13b of the second wall edge segment 12 and the third wall edge segment 13 may be at an angle other than a right angle.
