Description

[Technical Field]

[0001] The present invention relates to a disaster prevention house that can protect human lives and property from natural disasters and man-made disasters such as flood damage, snow damage, and landslides by raising living space and storage shelves for property or vehicles to a sufficient height. [Background technology]

[0002] Flooding or snow damage, such as river flooding, high tides, and landslides, can result in loss of life and property, and the expense, time, and effort required to remove the large amounts of mud and debris that have gotten into living spaces and under floors, or the snow that has accumulated on roofs and under eaves, can be enormous.

[0003] Large-scale civil engineering structures such as levees, floodgates, seawalls, and breakwaters have been constructed on rivers and coasts, and much public investment has been made, but these have not been sufficient to completely prevent disasters.In addition, there have been many reports of flood damage caused by breaks in water mains in recent years, and this is a man-made disaster that can occur anywhere, anytime, when water pipes are damaged due to aging or when replacement work is being carried out.

[0004] Measures that ordinary residents can take to prevent flooding include raising the ground level and stacking sandbags to block water.

[0005] In addition, in areas with heavy snowfall, snow piles up in front of the entrance and blocks the entrance, so it is necessary to clear it away, and snow that has accumulated on the roof also needs to be removed. This is done by climbing onto the roof, cutting it off with a shovel, and throwing it down, but this is extremely hard work and dangerous work, with frequent accidents such as falling from the roof or falling snow occurring. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent 6864391 [Patent Document 2] Patent 6691633 [Patent Document 3] Patent Publication No. 2007-126862 [Patent Document 4] Mito 3110611 [Patent Document 5] Patent Publication No. 2000-274038 [Patent Document 6] Patent 3642747 [Patent Document 7] Mito 3122843 Summary of the Invention [Problem to be solved by the invention]

[0007] In recent years, various devices have been developed to prevent flooding, and there have been proposals for technologies that raise a house above water to prevent flooding of living spaces when the water level rises (see, for example, Patent Document 1 and Patent Document 4). However, although the house will naturally descend as the water level subsides and recedes, there is a problem in that if the large amount of mud, rubble, driftwood, and other floating debris that has gotten into the foundations and under the floors of the house is not removed, there is a high possibility that the house will not be able to stay in its original position.

[0008] Furthermore, there have been proposals for structures that allow the living space to be moved upward to avoid being affected by tsunamis, floods, earthquakes, and mudslides, and that slide upward along multiple supports supported by foundation concrete buried under the ground (see, for example, Patent Documents 2 and 3). However, Patent Document 2 has a problem in that the supports are formed to penetrate vertically through the center of the living space, making it highly likely that the structure will be difficult to provide a large living space. Furthermore, Patent Document 3 has a structure in which the living space is lifted by a motor-driven wire rope, but the wire rope, movable pulley, and fixed pulley are exposed from the ground (GL) in the external space below the floor, making it highly likely that they will be damaged or cut by driftwood or other floating objects.

[0009] Furthermore, in recent years, various snow removal devices have been proposed to allow snow that has accumulated on a roof to be removed without the need to climb onto the roof (see, for example, Patent Document 5). However, snow removal devices are complex and require a mechanical drive source, and they have the problem of requiring many installation parts and installation processes, resulting in frequent breakdowns and maintenance inspections, as well as being large-scale and too expensive for the general public to use.

[0010] There have also been proposals to promote natural snow removal by installing snow removal sheets that do not require a mechanical drive source (see, for example, Patent Documents 6 and 7). However, irregular snowfall occurs frequently, making it easy for accidents and damage to occur due to snow falling under the eaves. In addition, when removing snow that has not fallen naturally, there are issues in that the roof is slippery due to the special sheet that has a reduced coefficient of friction, increasing the risk of accidents involving falls.

[0011] Furthermore, the proposals mentioned above, which involve manually adjusting snow removal by installing snow removal devices that require a mechanical drive source, or snow sheets, or promoting natural snow removal, still have fundamental issues, such as the fact that snow that falls under the eaves blocks the entrance in front of the front door and therefore requires snow removal, which still requires a lot of manpower and money.

The lifting mechanism 4 and conversion device 5 are also structured so that multiple units can be linked together to adjust their elevation, and can be linked together with a drive shaft 8, or electronically controlled to adjust their elevation as a unit. In addition, as a safety measure to prevent accidents when the living space is raised or lowered, multiple motion sensors and obstacle sensors are installed indoors and outdoors, and when an obstacle is detected by the sensor, the transmission mechanism that transmits power to the lifting device is automatically switched to a neutral state to stop the lifting mechanism 4, and when an obstacle is detected, a red light flashes and an alarm is issued (for example, an announcement is made that the living space will rise or fall by pressing a button that is flashing because an obstacle has been detected).

Figure 4 is a cross-sectional view taken along line BB, showing the movable base 14 lowered in its normal state, and shows the PC slab 3 laid on the ground, and the movable base 14 placed on the building foundation member 17. Also shown are the conversion device 5 attached to the beam of the box culvert 2, the drive shaft 8 between the conversion device 5, and the lifting mechanism base 10 and the lifting mechanism base connecting beam 11 between the lifting mechanism base 10. Figure 5 is a cross-sectional view along line CC showing the movable base 14 in its lowered state under normal conditions, and shows the box culvert 2, PC slab 3, and building wall 16 laid on the ground, as well as the lifting mechanism 4 and conversion device 5 attached to the top of the beams of the box culvert 2, and the base lifting device 7 connected to the movable base 14. Also shown is a U-shaped detachable guide shoe 9 surrounding the building wall 16.

[0043] 6 to 9 are side views showing the basic structure, configuration, and mechanism of a disaster prevention home according to the present invention (see the orientation in FIG. 1). FIG. 6 is a side view showing the south side with the movable base 14 lowered in normal operation, and illustrates a structure in which the living space arranged on the movable base 14 can be adjusted up and down by sliding along guide rails 13 installed vertically on the wall surface of the building wall 16, guided by guide rollers 12 attached to detachable U-shaped guide shoes 9 surrounding the building wall 16. Also shown is a structure in which the lifting mechanism control panel 6, private power generation device 22, power storage device 26, outdoor equipment 21, and other equipment and devices attached to the detachable guide shoes 9 can be adjusted up and down as a unit with the detachable guide shoes 9, protecting them from flooding and submersion, reducing the possibility of malfunction or damage, and facilitating inspection and maintenance. Figure 7 is a side view showing the east side with the movable base 14 lowered in its normal state, and shows a structure in which the fitted guide frame 36 on the side wall of the box culvert 2 is connected to a U-shaped detachable guide shoe 9 surrounding the building wall 16, and the movable base 14 slides along guide rails 13 installed vertically on the side wall of the box culvert 2 and the wall surface of the building wall 16, allowing the living space located on the movable base 14 to be adjusted in height. Figure 8 is a side view showing the west side with the movable base 14 lowered in its normal state, and shows a structure in which the living space can be adjusted in height, as in Figure 7. Figure 9 is a side view showing the north side with the movable base 14 lowered in its normal state, and shows a structure in which the living space can be adjusted in height, as in Figure 6.

[0044] Figures 10 and 11 show the basic structure, configuration, and mechanism of a disaster-prevention home according to the present invention, showing a perspective view of the movable base 14 lowered during normal operation. Figure 10 shows a pair of through-holes 1 for a base lifting device formed in the beams at the top of the opposing walls of a box culvert 2, and illustrates a structure in which the living space can be vertically raised and lowered via the through-holes 1 for the lifting mechanism. Figure 11 shows a prefabricated house structure using the box culvert 2, in which a lifting mechanism 4 and a conversion device 5 are attached to the beams, and a base lifting device 7 is connected to the movable base 14 via the through-holes 1 for the lifting mechanism formed in the beams. The movable base 14 is configured to accommodate the entire floor of the living space, allowing the living space to be vertically raised and lowered. Furthermore, because the lifting mechanism 4 and the conversion device 5 are attached to the beams of the box culvert 2, they are located higher than ground level, protecting them from flooding and submersion, reducing the possibility of malfunction or damage, and facilitating inspection and maintenance.

[0045] Figures 12 and 13 show the basic structure, configuration, and mechanism of the disaster-resistant housing of the present invention, and are perspective views showing the living space elevated to a sufficient height. Furthermore, the building foundation member 17 is configured to accommodate the movable base 14. The removable building foundation member 29 between the box culverts 2 is movable, providing a work space for removing large amounts of mud, debris, driftwood, and other debris that have seeped under the floor as the floodwaters subside. In snowy regions, the removable building foundation member 29 can be moved to raise the living space to a sufficient height, allowing vehicles 54 to be stored under the floor to avoid snow accumulation 69 and providing access from the ground level. Figure 12 also shows that the lifting mechanism 4 and conversion device 5 attached to the beams of the box culvert 2 are configured with protruding rods, such as rack girders, spindle rods, or cylinder rods, and therefore requires a decorative chimney 50 to conceal the protruding rods that penetrate the roof 46. Figure 13 shows that the lifting mechanism 70 and conversion device 71 attached to the beam portion of the box culvert 2 are configured without protruding rods such as wire ropes or chains, and therefore there is no need for a decorative chimney 50 to cover the protruding rods that penetrate the roof 46.

[0046] Figures 14 and 15 are perspective views showing the basic structure, configuration, and mechanism of the disaster prevention home of the present invention in a skeleton format. Figure 14 shows the movable base 14 in a lowered state, which is normal, and Figure 15 shows the living space raised to a sufficient height, which makes it possible to protect human life and property from disasters. In addition, the home is equipped with a sloped staircase 24 that can be adjusted to rise and fall, so it can be accessed at any time even when the living space is raised or lowered to the required height.

[0047] 16 and 17 are perspective views showing an example of the exterior of a disaster prevention home according to the present invention, and show that the lifting mechanism 4 and conversion device 5 attached to the beams of the box culvert 2 are configured with protruding rods such as rack girders, spindle rods, or cylinder rods, and therefore a decorative chimney 50 is required to cover the protruding rods that penetrate the roof 46. Also, Fig. 16 shows the state in which the movable base 14 is lowered, which is normal, and Fig. 17 shows the state in which the living space has been raised to a sufficient height to protect human life and property from disasters.

[0048] 18 and 19 are perspective views showing an example of the exterior of a disaster prevention home according to the present invention, and show that the lifting mechanism 70 and conversion device 71 attached to the beams of the box culvert 2 are configured without protruding rods such as wire ropes or chains, and therefore there is no need for a decorative chimney 50 to cover the protruding rods that penetrate the roof 46. Also, Fig. 18 shows the state in which the movable base 14 is lowered, which is normal, and Fig. 19 shows the state in which the living space has been raised to a sufficient height, making it possible to protect human life and property from disasters.

[0049] 20 and 21 are perspective views showing an example of the exterior of a disaster prevention home according to the present invention, with the lifting mechanism 4 and conversion device 5 installed outdoors in the longitudinal direction of the structure. By installing the lifting mechanism 4 and conversion device 5 outdoors, there are fewer restrictions within the living space, allowing for greater freedom. Furthermore, even for existing structures, the lifting function of the structure can be ensured by retrofitting a movable base 14 under the floor and installing the lifting mechanism 4 and conversion device 5 outdoors. Figure 20 shows the state in which the movable base 14 is lowered, which is normal, while Figure 21 shows the state in which the living space has been raised to a sufficient height, making it possible to protect human lives and property from disasters.

[0050] The configuration in which the lifting mechanism 4 and conversion device 5 are installed outdoors as described above allows for effective use of underground space. For example, by installing a large float underground, the lifting mechanism 4 can be manually operated in the event of a power outage or malfunction, and an automatic floating float can also be operated as an auxiliary function.

[0051] 22 and 23 are perspective views showing an example of the exterior of a disaster prevention home according to the present invention, with the lifting mechanism 4 and conversion device 5 installed outdoors along the short side of the structure. Installing the lifting mechanism 4 and conversion device 5 outdoors reduces restrictions within the living space, allowing for greater freedom. Even for existing structures, the lifting function of the structure can be ensured by retrofitting a movable base 14 under the floor and installing the lifting mechanism 4 and conversion device 5 outdoors. Figure 22 shows the state in which the movable base 14 is lowered, which is normal, while Figure 23 shows the state in which the living space has been raised to a sufficient height to protect human lives and property from disasters.

[0052] Figures 24 and 25 are side views showing an example of a parking facility for a disaster-prevention home according to the present invention. The lifting mechanism 70 and conversion device 71 attached to the beams of the box culvert 2 equipped with an attic storage room 79 are configured without protruding rods such as wire ropes or chains, eliminating the need for a decorative chimney 50 to conceal the protruding rods penetrating the roof 46. Furthermore, the structure is equipped with a sloped staircase 24 that can be adjusted for elevation, allowing access at all times even when the storage shelf 67 for vehicle 72 and the movable base 14 are raised or lowered to the required height. Figure 24 shows the storage shelf 67 for vehicle 72 and the movable base 14 in their normal lowered state, while Figure 25 shows the state in which the movable base 14 for the storage shelf 67 for vehicle 72 is raised, enabling the protection of life and property from disasters.

[0053] Figures 26 and 27 are perspective views showing, in a skeletonized format, a detachable trailer house for disaster prevention housing according to the present invention, divided into sections for transport by a tow vehicle when completed or semi-finished. The trailer 41 is configured to tow the finished or semi-finished product in accordance with the Road Law's Vehicle Restrictions Ordinance, and is equipped with a folding roof 32, a folding decorative chimney 49, and folding walls 33, and measures are taken to enable transport by a tow vehicle, such as to overcome height restrictions. The detachable trailer house base also functions as a chassis 37 and is equipped with a coupling device 42, allowing for the rapid supply of various types of facilities as needed for factory production, transportation, installation, and removal. Figure 26 shows an image of a detachable trailer house divided into sections for transport by a tow vehicle when completed or semi-finished, and Figure 27 shows an image of a detachable trailer house divided into sections for transport by a tow vehicle when completed, such as to overcome height restrictions, with a folding roof 32, a folding decorative chimney 49, and folding walls 33.

[0054] Figures 28 and 29 are perspective views showing the structure of a prefabricated house and the folding and assembly of a detachable trailer house for disaster prevention housing according to the present invention. The trailer 41 is designed to tow a completed or semi-finished product in compliance with the Road Law's Vehicle Restrictions Ordinance, and is equipped with a folding roof 32, a folding decorative chimney 49, and folding walls 33. Measures are taken to accommodate towing vehicle transport, such as height restrictions. The chassis 37 of the detachable trailer house has a movable base 14 structure on which the entire floor of the living space can be installed, and functions as a movable base 14 that can be fitted into the box culvert 2, which is the structure of the prefabricated house. The living space can be constructed not only on-site but also in a factory. The completed or semi-finished living space can be towed and transported by trailer 41 and installed on-site, reducing construction costs and shortening construction time. Furthermore, the trailer 41 has the function of supplying a wide variety of temporary living facilities, accommodation facilities, and limited-use structural facilities needed in disaster-stricken areas as needed from areas where factory production is possible. Figure 28 shows the external appearance of an assembled image of detachable trailer house divided 1 unit 31 using the two-piece box culvert upper part 44, the two-piece box culvert lower part 47, the two-piece building wall upper part 45, and the two-piece building wall lower part 48 of the prefabricated house structure, and Figure 29 shows the external appearance of an assembled image of detachable trailer house divided 1 unit 31 using the two-piece box culvert upper part 44, the two-piece box culvert lower part 47, the two-piece building wall upper part 45, and the two-piece building wall lower part 48 of the prefabricated house structure.

[0055] 30 and 31 are perspective views showing a skeleton of a disaster prevention home equipped with a snow removal sheet device according to the present invention. The snow removal sheet device, installed in snowy regions, utilizes the sliding action of the upper and lower roof sheets, formed by folding back a single roof sheet, to slide off the snow layer on the roof together with the flexible sheet 51. This allows snow to effectively slide off the roof without requiring anyone to climb onto the roof. Furthermore, the lifting mechanism 70 and conversion device 71 attached to the beams of the box culvert 2 are configured without protruding rods such as wire ropes or chains, eliminating the need for a decorative chimney 50 to conceal the protruding rods that penetrate the roof 46, and thus facilitating the installation of the flexible sheet 51. Figure 30 shows a skeleton diagram of the movable base 14 in its lowered state under normal conditions, while Figure 31 shows a skeleton diagram of a single flexible sheet 51 stretched over the sloped roof surface, folded back to form a double layer, with the upper flexible sheet 51 having a roughened surface with high frictional resistance to allow snow to accumulate, and the back surface of the upper flexible sheet 51 and the top surface of the lower flexible sheet 51 having low frictional resistance to allow the upper flexible sheet 51 to smoothly drop along with the accumulated snow 69. The diagram also shows a state in which the living space has been raised to a sufficient height to protect human life and property from disasters.

[0056] 32 and 33 are perspective views showing flexible sheet 51 connected to winding device 52 installed on the ridge of a disaster-resistant home equipped with the snow removal sheet device of the present invention by strong string, rope, wire, metal fittings, or other wire material 61 via connecting rod 57 and fixture 85. Snow removal sheet devices installed in snowy areas can be used repeatedly, and flexible sheet 51 that falls with accumulated snow 69 and hangs down toward the eaves has strong rope or wire material 61 connected to one edge via connecting rod 57 and fixture 85, and wire material 61 can be wound up by winding device 52 and returned to its original position, allowing snow accumulated on the roof to be effectively slid off without the need for anyone to climb onto the roof. Figure 32 shows the state in which the winding device 52 installed on the ridge of the disaster prevention home is opened and the flexible sheet 51 and snow 69 are allowed to fall along the slope, and Figure 33 shows the state in which the winding device 52 installed on the ridge of the disaster prevention home is opened and the flexible sheet 51 and snow 69 are allowed to fall along the slope.

[0057] 34 and 35 are perspective views showing an example of the exterior of a disaster prevention home equipped with a snow removal sheet device according to the present invention. This home is configured so that, in snowy regions, the snow removal sheet device and the movable base 14 can be raised to create a temporary indoor parking space under the floor where vehicles 54 can be stored. In snowy regions, the entrance to the front door can be blocked by falling or accumulated snow 69, making snow removal necessary. However, by raising the living space to the required height, it is possible to enter and exit from above the falling or accumulated snow 69. Furthermore, by raising the living space to a sufficient height, vehicles 54 can be stored under the floor to avoid the accumulated snow 69, allowing for entry and exit from the ground level. Figure 34 shows the state in which the movable base 14 is lowered, which is normal, while Figure 35 shows the living space in snowy regions, where it can be raised to a sufficient height to store vehicles 54 under the floor to avoid the accumulated snow 69, allowing for entry and exit from the ground level.

[0058] Figures 36 to 39 are perspective views showing the basic structure, configuration, and mechanism of the disaster prevention home of the present invention. Furthermore, in this disaster prevention home, a box culvert 2, which is a structural element of a prefabricated house, and a pair of PC slabs 3 form one unit. A lifting mechanism 70 and a conversion device 71 are attached to the upper beams of the box culvert 2. A foundation lifting device 7 is connected to a movable base 14. The living space located on the movable base 14 is comprised of multiple interconnected units. The lifting mechanism 70 and conversion device 71 attached to the beams of the box culvert 2 are configured without protruding rods such as wire ropes or chains, eliminating the need for a decorative chimney 50 to conceal the protruding rods penetrating the roof 46. The lifting mechanism 70 and conversion device 71 are also configured to enable linked lift adjustment across multiple units. These include a structure in which the lifting mechanism 70 and conversion device 71 are connected by a drive shaft 8, and an example in which the lifting mechanism 70 and conversion device 71 can be integrated and linked via electronic control. Figure 36 is a perspective view of a disaster prevention home comprised of multiple interconnected units, with the movable base 14 lowered, representing normal operation. Figure 37 is a perspective view showing an example of the exterior of a disaster prevention home made up of multiple linked units. Figure 38 is a perspective view showing a disaster prevention home made up of multiple linked units with the living space raised to a sufficient height to protect human lives and property from disasters. Figure 39 is a perspective view showing an example of the exterior of a disaster prevention home made up of multiple linked units with the living space raised to a sufficient height.

[0059] Figure 40 is a plan view showing an embodiment in which an automatic floating underground facility 80 is provided in a prefabricated house structure for disaster prevention housing according to the present invention. In a prefabricated house structure using box culverts 83, one box culvert 83 and a pair of PC slabs 82 constitute one prefabricated house structure unit 20, allowing for effective use of underground space, and by installing a large float underground, for example, it is possible to manually respond to unforeseen events such as a power outage or malfunction of the lifting mechanism 4, and it is also possible to operate the automatic floating float as an auxiliary function.

[0060] Figure 41 is a perspective view showing the basic structure, configuration, and mechanism of a disaster prevention home according to the present invention, showing the movable base 14 lowered during normal operation. In a prefabricated house structure using box culverts 83, a lifting mechanism 4 and a conversion device 5 are attached to the beams, and a base lifting device 7 is connected to the movable base 14 via a through-hole for the lifting mechanism 1 formed in the beams, allowing the entire floor of the living space to be installed on the movable base 14. The box culverts 83 and PC slabs 84 laid on the ground have openings for underground storage facilities, allowing for effective use of underground space. For example, by installing a large float or underground storage facility underground, an automatic floating float can be operated as a supplementary function to the manual operation of the lifting mechanism 4. This is a perspective view showing an example.

[0061] Figures 42 to 44 are cross-sectional views along the cross-sectional line indicated in Figure 40, which shows the basic structure, configuration, and mechanism of a disaster prevention home according to the present invention. Figure 42 is a cross-sectional view along line DD, showing the movable base 14 lowered under normal conditions. It shows a box culvert 83 and a PC slab 84 laid on the ground, and the movable base 14 placed on a building foundation member 17. An automatic floating float 74 and an automatic floating underground facility 80 are installed underground, surrounded by an underground wall 87. An inflow space 86 is provided between the underground wall 87 to effectively absorb buoyancy. This structure allows for flooding during floods or intentional water inflow, creating buoyancy. This example also shows an example in which the automatic floating float can be operated as an auxiliary function of the lifting mechanism 4. Also shown are the lifting mechanism 4 and the lifting mechanism base 10 attached to the beams of the box culvert 2. Figure 43 is a cross-sectional view taken along line E-E, showing the movable base 14 lowered under normal conditions, and shows the movable base 14 placed on a PC slab 84 laid on the ground and a building foundation member 17. An automatic floating float 74 and an automatic floating underground facility 80 surrounded by an underground wall 87 are installed underground, and an inflow space 86 is provided in the gap with the underground wall 87 to effectively absorb buoyancy. Also shown is a drainage pump pit 81 installed at the bottom of the underground wall 87 as a structure for lowering the movable base 14 once the floodwaters have subsided. Also shown are the conversion device 5, the drive shaft 8 between the conversion device 5, attached to the beam of the box culvert 83, and the lifting mechanism base 10 and the lifting mechanism base connecting beam 11 between the lifting mechanism base 10. Figure 44 is a cross-sectional view along line FF showing the movable foundation 14 in its lowered state under normal conditions, and shows a box culvert 83, a PC slab 84, and a building wall 16 laid on the ground, with a lifting mechanism 4 and a conversion device 5 attached to the top of the beams of the box culvert 83, and a foundation lifting device 7 connected to the movable foundation 14. An automatic floating float 74 and an automatic floating underground facility 80 surrounded by an underground wall 87 are installed underground, and an inflow space 86 is provided in the gap with the underground wall 87 to effectively receive buoyancy. Also shown is a U-shaped detachable guide shoe 9 surrounding the building wall 16.

[0062] Figure 45 is a perspective view showing the basic structure, configuration, and mechanism of a disaster prevention home according to the present invention, with the living space elevated to a sufficient height. In a prefabricated house structure using box culverts 83, a lifting mechanism 4 and a conversion device 5 are attached to the beams, and a base lifting device 7 is connected to a movable base 14 via a lifting mechanism through-hole 1 formed in the beams. The entire floor of the living space can be installed on the movable base 14. The box culverts 83 and PC slabs 84 laid on the ground have openings for underground storage facilities, allowing for effective use of underground space. For example, by installing a large float or underground storage facility underground, automatic floating float operation can be performed as a supplement to the manual operation of the lifting mechanism 4. This is an example perspective view. [Industrial Applicability]

[0063] The present invention makes it possible to protect human life and property by raising the living space to a sufficient height to avoid flooding or submersion in a prefabricated house structure using a box culvert 2, using a lifting mechanism 4 and conversion device 5 attached to the beams. Because the lifting mechanism 4 has a similar movable structure and configuration to conventional water gates and sluice gates, it is possible to use mechanical parts in combination, which makes it possible to reduce development costs and manufacturing costs.
