Abstract
Description
[Technical Field]
[0001] The present invention relates to temporary housing, and more particularly to temporary housing that can be quickly set up in a desired location and used immediately after a major disaster such as an earthquake. [Background technology]
[0002] In the past, especially since the Great Hanshin-Awaji Earthquake in 1995, the importance of quickly establishing temporary housing to support evacuees in areas severely damaged by earthquakes and typhoons has been recognized and required. In Japan, the Disaster Relief Act stipulates that construction of temporary housing must begin within 20 days of the disaster, but in some cases it can take an extremely long time for disaster victims to move in. Furthermore, there are also cases where the Disaster Relief Act does not apply at all.
[0003] In light of this situation, Patent Document 1 proposes a type of rapid-construction temporary housing that is easy to assemble and responds to emergencies, is compact yet provides sufficient living space, and is comprised of a lower structure, upper walls, protruding structures, a ceiling, and an extension, which allows for compact storage in normal times, and can be stacked, secured, and transported in the event of an emergency, and can be assembled easily and securely at the installation site. However, the invention described in Patent Document 1 required on-site assembly, and the interior equipment of the house also needed to be set up on-site, so it took several days to deliver it to disaster-stricken areas such as mountainous and depopulated areas where it was difficult to get manpower and supplies.

[0026] Hereinafter, an embodiment of a temporary housing according to the present invention will be described with reference to the drawings.
[0027] [Embodiment 1] Figure 1 shows the temporary housing (1) of the present invention being lifted and lowered from the bed of a truck or a cart towed by a truck. Figure 1 shows the temporary housing (1) as seen from the front with its panels closed during transportation. The size of the box-shaped living space of the temporary housing (1) according to the present invention is not important, but it must be within the range that can be carried in a vehicle. In this embodiment, the bottom of the box-shaped living space is 2200 mm x 6000 mm and the height is 2600 mm so that it can be loaded onto a 4-ton truck and transported. A 4-ton truck can deliver the space to places without main roads, such as mountainous areas. The method of lowering the temporary housing (1) from the truck bed or the cart pulled by the truck is not limited to the lifting method, and the drawings should be understood as merely examples.
[0028] FIG. 2 is a front view showing the temporary housing (1) according to the present invention that has been lowered from the loading platform to the installation site in FIG. 1, with the panel provided on the entrance side of the box-shaped living space (2) opened. An entrance (15) is provided inside the open panel. The entrance (15) can be a sliding door or an outward-opening door. Having the entrance (15) inside the eaves with the panel open gives residents a sense of security.
[0029] FIG. 3 is a side view of the temporary house (1) according to the present invention in the state shown in FIG. The box-shaped living area (2) has a panel (13) on the side facing the entrance that opens upward to form a canopy. The open panel (13) may be supported at its outer edge by a pole (16). A deck (14) is preferably installed under the canopy to be used as a terrace (3) at the entrance.
[0030] A rainwater tank (9) is installed on one side of the box-shaped living area (2), and rainwater from a rain gutter (10) is accumulated in the rainwater tank (9). The rainwater accumulated in the rainwater tank (9) passes through a water purification system (11) and is supplied as purified water to the kitchen and private rooms in the living area. If there is a river or lake near the temporary housing, a pump can be installed in the tank (9) to draw water from the river or lake and send it to a water purification facility (11) for use as purified water. The water purification equipment (11) is preferably equipped with a filter, RO filtration, and ultraviolet sterilization equipment.
[0031] As shown in Figure 4, the house is equipped with solar panels (12) on the roof and has pipes for purified water, sewage, and electricity on the rear exterior wall, so that purified water and electricity can be used even when the lifelines are not restored. The solar panel (12) provided on the roof is, for example, 12 square meters, but is not limited to this. Propane gas can also be used if a gas tank and gas piping are prepared and installed in advance. Of course, a portable household gas stove can also be provided.
[0032] The water purification system (11) preferably includes a water purification device and a purified water tank, and purifies rainwater from the rainwater tank (9) during times of low electricity demand, such as at night, and stores it in the purified water tank. The purified water tank is connected to the kitchen and private rooms via the waterworks. It is advisable to provide a water storage tank in the kitchen so that there is no shortage of purified water in the kitchen even if a large amount of purified water is used in the private room showers. A purified water tank with a capacity of, for example, 2 cubic meters allows for a life without worrying about water supply.
[0033] The solar panel (12) is preferably connected to a power supply device including a converter and a storage battery, so that power can be supplied to the temporary housing regardless of whether it is in sunlight or not.
[0034] As shown in FIGS. 3 and 4, the living room and the private room may be provided with a ventilation system (17).
[0035] As shown in FIG. 4, the kitchen and private rooms of the living room are provided with piping on the exterior walls that connects the water supply line (20) and the sewer line (21) over the shortest distance.
[0036] FIG. 5 is a cross-sectional view taken along line B in FIG. The box-shaped living area (2) has a steel frame with wooden walls, floors, and ceilings. In this embodiment, 100mm x 100mm column pipes are used as the core material, and cypress wood is used for the interior and exterior walls, but this is not limited to this. It is preferable to place insulation material between the interior and exterior walls. A roof may be provided on top of the box-shaped living area (2). The roof may be any shape, such as gable, shed, or hipped, but it must be kept to a height that allows it to be loaded onto a truck and transported.
[0037] The panel 13 may be made of, but is not limited to, wood, fiber-reinforced plastic (FRP), etc. The size of the panel 13 can be selected arbitrarily as long as it does not exceed the size of the side surface on the entrance side of the box-shaped living area 2. Preferably, the size is selected to cover at least the glass-covered portion of the side surface on the entrance side. The panels (13) are attached to the exterior of the box-shaped living area (2), which has an entrance (11), using hinges, stays, hinges, etc. The panels (13) are preferably supported by poles (16) that open upward to form a canopy over the entrance. The poles (16) can be made of any material, such as square bars, round bars, or pipes made of wood, aluminum, or steel. They only need to be strong enough to support the weight of the panels (13). Preferably, the outer edges of the panels (13) are supported by poles (16) approximately every 2 m from the center to both ends. By installing a separately manufactured deck (14) on the eaves, it becomes a terrace (3) at the entrance, improving the quality of the living space. The deck (14) is an important part that, together with the panels, constitutes the exterior of the temporary housing, so it is preferable to make it out of wood such as cypress.
[0038] FIG. 6 is an exploded perspective view of one embodiment of a temporary house according to the present invention. As shown in Figures 5 and 6, the temporary housing (1) comprises a box-shaped living area (2) and a terrace (3) with panels (13) as eaves and a deck (14) as the floor, and the box-shaped living area (2) comprises a living room (4) and a private room (5). The living room (4) is equipped with living facilities such as a bed (6), kitchen (7), and air conditioner (8), and the private room (5) is equipped with a washroom, bath, shower, and toilet. The kitchen (7) is equipped with a refrigerator, sink and stove. The stove runs on electricity, but gas can also be used if gas equipment is installed in advance. It is also advisable to have a television or other important source of information in the room.
[0039] The kitchen (7) and private rooms (5) in the box-shaped living area (2) are supplied with purified water from a water purification system. Electricity for the kitchen (7), air conditioner (8), television, water heater, lighting, and other appliances inside and outside the home is supplied by solar panels (12).
[0040] Figure 7 is a cross-sectional view of a temporary housing unit according to one embodiment of the present invention. The living room (4) is equipped with a bed (6), a kitchen (7), and an air conditioner (8), and the private room (5) is equipped with a washroom, a bathroom shower, and a toilet, so that residents can start living there immediately. It is also preferable to prepare a dining table, chairs, and rods for hanging clothes in the living room (4) in advance.
[0041] [Embodiment 2] Figure 8 shows the framework of the temporary housing, which was constructed in two parts, upper and lower. In this embodiment, all equipment inside the box-shaped living space can be fixed to the framework in advance and transported. Water, sewerage, and electrical pipes are installed under the flooring. The panels form a canopy on the entrance side when installed.
[0042] When transporting by truck, if the upper part (18) of the frame is assembled with the lower part (19) of the frame and loaded onto the truck bed, one temporary housing unit can be loaded at half the height. This makes it possible to transport multiple temporary housing units at the same time by stacking the frame of another temporary housing unit on top of the frame of one already loaded. For example, if the lower part of one frame is attached to the lower part of another frame and loaded onto a loading platform, and then the upper part of another frame is attached to the upper part of the frame and placed on top of that, it would be possible to transport four temporary housing units at a time, and there is no limit to the number of units that can be loaded.
[0043] The lower (19) and upper (18) parts of the framework are fixed together by fitting steel frames together, fastening bolts, etc., so as to maintain the strength of the house.
[0044] As shown in Figure 9, after transportation, the temporary housing of this embodiment is installed at the installation location by placing the lower part of the framework, fixing the upper part on top of it, opening the panels (13), and then covering it with a tent sheet that has waterproof, fireproof, heat-insulating, and light-blocking properties to form an exterior.
[0045] Tent sheets that have waterproof, fireproof, heat-insulating, and light-blocking properties are selected from those with excellent functionality, such as polyester fabric coated with fluororesin or polyvinyl chloride. It is preferable to select an appropriate material depending on the environment of the installation location, such as heat insulating performance, light blocking performance, heat ray reflecting performance, soundproofing performance, etc.
[0046] If solar panels are placed on the eaves of the panel (13) on the entrance side, at least 12 square meters of solar panels can be used in this embodiment.
[0047] According to the temporary housing of the present invention, temporary housing where disaster victims can live safely and cleanly can be delivered as quickly as possible even in the event of a disaster. The implementation modes are not limited to the embodiments described herein, and it will be obvious to those skilled in the art that the present invention can be applied to various modes, provided that the requirements are that it can be mounted on a vehicle, that it has good weight balance when moving and setting up, that it can be easily set up and used by a small number of people, and that it has sufficient facilities to ensure safety and cleanliness in daily life. [Industrial Applicability]
[0048] According to the present invention, in the event of an emergency, temporary housing can be provided that can be transported to the required location and set up immediately, even in disaster-stricken areas where manpower and supplies are difficult to reach, such as mountainous or depopulated areas. More specifically, even before the government is ready to construct large-scale temporary housing, pre-prepared housing that is well-balanced for transportation and temporary set-up and allows immediate use can be transported on a truck or a cart towed by a truck, and easily set up in the desired location, supporting the lives of at least one disaster-stricken household as a single temporary housing unit. Furthermore, even if the temporary housing is box-shaped, providing a terrace can give it the appearance of being a dwelling for people, helping disaster victims return to their daily lives.
