Description

The present invention relates to a bedroom-combined shelter that can be used as a bedroom in normal times and as a shelter in floods.

In recent years, many floods have occurred beyond expectations. For example, Typhoon No. 19 that occurred on the eastern sea of the Mariana Islands on October 6, 2019 landed in Japan on the 12th. The typhoon continued to rain heavily over a wide area. Due to this heavy rain, the banks of the Abukuma and Chikuma rivers broke, and the rivers flooded and broke one after another. It is said that the inundation area exceeded the heavy rain in western Japan (about 18,500 hectares), which occurred in July 2018 and became an unprecedented heavy rain. Furthermore, during the heavy rains of July 2nd year of Reiwa, the Kuma River system flowing through Kumamoto Prefecture was flooded and destroyed in a total of 13 locations in Yatsushiro City, Ashikita Town, Kuma Village, Hitoyoshi City, and Sagara Village, flooding approximately 1060 hectares. .. At the special nursing home for the elderly "Senjuen" in Kuma Village, 14 people who had been admitted to the submerged facility died. It is thought that one of the reasons was that the evacuation was not in time due to the sudden rise in the water level at night.

As a countermeasure, it is considered possible to respond to these disasters by taking measures such as building a house on a hill. However, it is not realistic for all houses to be relocated to higher ground, and even if such measures are taken, damage such as inundation cannot be prevented. For example, during heavy rains, the drainage capacity of rainwater may be exceeded and rainwater may flow back from the manhole and spout out, causing frequent inundation damage even in relatively high-rise houses. In the Great East Japan Earthquake, inundation damage and submersion damage due to the tsunami occurred even in relatively high land.

Patent Document 1 assumes that the evacuation room is covered with a shelter outer shell having a strength against the tsunami, and the evacuees can be kept safe even if the evacuation room has a lower cost than the expected tsunami height. A tsunami shelter that has been made to hang down is disclosed. Specifically, it is a shelter provided with a floating floor that can take in tsunami water in the evacuation room and float on the taken in tsunami water.

Japanese Unexamined Patent Publication No. 2014-43746

However, with conventional shelters, when a tsunami or flood is predicted, it is necessary to evacuate to a place other than the place where one normally lives. Therefore, there is a problem that people who are lame or who spend most of the day in bed and need long-term care cannot evacuate without the help of others and are delayed in escaping. Also, for those who can evacuate on their own without the help of others, if a flood occurs and the water level rises sharply while sleeping, they cannot detect the sudden rise in water level and escape. There was the problem of being late. Further, the shelter disclosed in Patent Document 1 has a problem that the internal air pressure rises as the floating floor rises, and the physical load on the evacuees increases.

An object of the present invention is a shelter that can be used as a bedroom in normal times and does not require evacuation to another place even in the event of a tsunami or flood, and a shelter that can reduce the physical load when evacuating. Is to provide.

The invention for solving the above-mentioned problems is a shelter for flood damage that also serves as a sleeping room, and is provided with an intake for taking in outside air and taking in flood water when the water level rises in the event of a flood. It is equipped with a shelter housing that is fixed to the ground and a float floor that rises and falls inside the shelter housing as the water level rises and falls. It is characterized in that an air hole for taking in is defined.

According to this configuration, a float floor that rises and falls inside the shelter housing as the water level rises and falls in the event of a flood is provided, so even if flood damage occurs while sleeping, it will be on a separate hill. You can secure your own safety without evacuating to an evacuation site such as. Further, since the outside air can be taken into the internal space through the intake and the air hole in sequence, a window for ventilation is not required even when the outside air is used as a bedroom in normal times.

Preferably, the air holes are provided at a position higher than the intake.

According to this configuration, the air hole is provided at a position higher than the intake, so that flood water flows into the internal space from the air hole even if the water level rises sharply when a tsunami or flood occurs. Can be avoided.

Preferably, the shelter housing has a pressure reducing valve that keeps the internal space at a predetermined air pressure by discharging the air in the internal space when the float floor rises, and stops the rise of the float floor and closes the air holes. It is characterized by having a rising stationary member.

According to this configuration, since the pressure reducing valve that keeps the internal space at a predetermined atmospheric pressure is provided, it is possible to suppress an excessive increase in atmospheric pressure and reduce the physical load on the evacuees. Further, since it has a rising stationary member that closes the air holes, it is possible to prevent the inflow of flooded water into the internal space even when the water level rises.

Preferably, it comprises an air supply device that supplies air to the interior space when the water level reaches the upper end of the intake.

According to this configuration, even when the water level reaches the upper end of the intake and the supply of the outside air to the internal space is cut off, the air can be supplied to the internal space by the air supply device.

Preferably, it is provided with a nursing bed fixed to the float floor.

According to this configuration, a nursing bed that is fixed to the float floor is provided, so even those who are bedridden and need nursing care can stay in the nursing bed without evacuating to another place, and the interior space. You can protect your safety from flood damage by staying in.

It is a layout drawing of a shelter that also serves as a bedroom. The same is a front sectional view. The same is a plan sectional view. It is a front sectional view of the shelter for a bedroom which explains the state when the water level of flood water rises.

Embodiments of the present invention will be described with reference to FIGS. 1 to 4.

As shown in FIG. 1, the bedroom-combined shelter 1 (hereinafter referred to as shelter 1) is provided on the first floor of the house 100, and can be used as a bedroom in normal times, and is safe for the body in the event of flood. It is a shelter that can secure. It may be provided when the house 100 is newly constructed, or it may be provided by remodeling.

As shown in FIG. 2, the shelter 1 has a shelter housing 10, a float floor 20, an air supply device 30, a nursing bed 40, and a foundation 120 for fixing the shelter housing 10. The foundation 120 has a pile 122 that penetrates into the ground 110 and a footing 121 that fixes the upper end portion of the pile 122 and the lower end portion of the shelter housing 10. As a result, the shelter housing 10 is firmly fixed to the underground 110 via the foundation 120, so that it will not be washed away even when a tsunami or flood strikes. Further, the foundation 120 is connected to the foundation of the house 100.

The shelter housing 10 has a strength that can withstand a tsunami or a flood, and a predetermined watertightness that can suppress the intrusion of flooded water into the inside. It has a member 15. Further, a window 16 and a door 17 for going back and forth between indoors and outdoors are provided. The window 16 is intended for so-called daylighting, in which light from the outside is taken into the room, and is preferably a fixed type that cannot be opened or closed. As a result, it is possible to avoid the intrusion of flood water from the gap of the window 16. The door 17 is of an outward opening type (see FIG. 3), and it is preferable to provide a packing for ensuring a predetermined watertightness performance.

The intake 11 is for taking in the outside air as well as the flooded water in the event of a flood, and is composed of three openings in contact with the external space. The lower end of the intake 11 is set higher than the underground 110, and the upper end is set lower than the air hole 25.

The rising rest member 15 is for stopping the float floor 20 at a predetermined height and closing the air holes 25 when the float floor 20 is stationary at a predetermined height. It is an annular plate member provided at a constant height and extends horizontally to the inside. Further, a packing for stopping water is provided in an annular shape at the tip portion.

The pressure reducing valve 12 has only a function of discharging the air of the internal space 150 to the outside when the float floor 20 rises, and does not have a function of taking in the outside air when the air pressure of the internal space 150 drops. It is a so-called check valve and is provided on the ceiling portion 10a. Here, the internal space 150 refers to a space defined by the shelter housing 10 and the float floor 20.

The float floor 20 is a multi-chamber box body filled with air, and is located inside the shelter housing 10. At the upper end portion, a horizontally extending flange portion 21 projects in an annular shape. The flange portion 21 is provided at a position higher than the upper end of the intake 11. The float floor 20 is normally placed on the footing 121. In the event of flood damage, the flooded water is taken in from the intake port 11 so that the inside of the shelter housing 10 rises as the water level inside the shelter housing 10 rises.

The collar portion 21 is defined with an air hole 25. The air hole 25 is for taking in the outside air taken in from the intake port 11 into the internal space 150 and discharging the air existing in the internal space 150. In the normal state, the outside air is taken in from the air hole 25, and the air in the internal space 150 is discharged to the outside through the air hole 25 and the intake port 11 in order, so that the internal space 150 does not open or close the window 16. Ventilation is possible.

The nursing bed 40 is fixed to the float floor 20. It is preferable that the nursing bed 40 is fixed at a position where the center of gravity of the float floor 20 when the float floor 20 rises and the center of gravity coincide with each other in a plan view. As a result, the float floor 20 can ascend while being kept horizontal. The upper surface of the float floor 20 is preferably flooring. Moreover, it is preferable to make it barrier-free. This can reduce the burden on those who care for and those who need it.

The air supply device 30 is for supplying air to the internal space 150 when the supply of outside air is cut off, and has a water level sensor 31 and an air cylinder 35. The water level sensor 31 is provided in the vicinity of the intake port 11 and measures the water level inside the shelter housing 10. The air cylinder 35 is placed on the float floor 20. Further, the structure is such that the measured value measured by the water level sensor 31 is constantly detected and air can be supplied to the internal space 150 when the measured value exceeds the threshold value.

In past flood cases, the maximum disaster period was two days, so it is preferable that the air cylinder 35 has a capacity to supply air that allows evacuees to survive in the internal space 150 for two days or more.

Explain evacuation in the event of a flood. Flood damage here includes not only disasters caused by floods but also disasters caused by tsunamis.

When a flood occurs and the water level rises, the flooded water is taken in from the intake port 11 and the water level inside the shelter housing 10 rises. As the water level rises, the float floor 20 begins to rise.

When the water level inside the shelter housing 10 reaches the upper end of the intake port 11 and it is determined that the measured value measured by the water level sensor 31 exceeds the threshold value, the air cylinder 35 supplies air to the internal space 150. .. As a result, air is continuously supplied from the air cylinder 35 to the internal space 150.

As the water level rises, the float floor 20 rises further. As the float floor 20 rises, the air pressure in the internal space 150 rises, but the compressed air in the internal space 150 is discharged to the outside by the pressure reducing valve 12, so that the internal space 150 exceeds a predetermined air pressure. There is no such thing. This can reduce the physical burden on those who are evacuating, especially those who need long-term care.

When the collar portion 21 reaches the height of the ascending stationary member 15, the ascending of the float floor 20 is restricted and stopped. At this time, the rising stationary member 15 closes the air hole 25, and the internal space 150 becomes a closed space that maintains a predetermined atmospheric pressure. Further, the closed air A (see FIG. 4) stays below the flange portion 21.

As shown in FIG. 4, the behavior until the water level L1 of the flooded water (hereinafter referred to as the water level L1) rises further and covers the ceiling portion 10a will be described.

Since the head of the flood-damaged water existing inside the shelter housing 10 and the head of the flood-damaged water existing outside are the same, the water level L2 (hereinafter referred to as L2) of the internal space 150 tends to be the same as the water level L1. At this time, the closed air A is compressed to suppress the rise of the water level L2. As a result, even if the water level L1 passes through the rising stationary member 15 and becomes higher than the ceiling portion 10a, the flood water does not infiltrate into the internal space 150 due to the rising water level L1. Further, the air pressure in the internal space 150 does not rise until the water level L1 becomes higher than the ceiling portion 10a.

As the water level L2 descends, the float floor 20 gradually descends. At this time, since the outside air is not taken in from the pressure reducing valve 12, the air pressure in the internal space 150 tends to decrease. However, since the internal space 150 is constantly supplied with air by the air cylinder 35, the internal space 150 can descend while securing a predetermined atmospheric pressure.

This embodiment is an example, and it is needless to say that the present embodiment can be modified without departing from the technical idea of the present invention. For example, in the present embodiment, the shelter is provided on the first floor of the house, but the height of the shelter may be increased to occupy the first and second floors of the house.

Further, in the present embodiment, the pressure reducing valve 12 is provided on the ceiling portion 10a, but may be provided at a position higher than the assumed flood water level. As a result, even when the water level L1 is higher than the ceiling portion 10a, the increase in atmospheric pressure is suppressed in the internal space 150, and a predetermined atmospheric pressure can be secured.

The bedroom-combined shelter according to the present invention can avoid flood damage without evacuating to another place when a flood or a tsunami occurs. In particular, by applying it in facilities for the elderly where people in need of long-term care live, it is possible to ensure the personal safety of many people in need of long-term care, so it has great industrial applicability.
