For this reason, the disaster prevention storage section 17 has a structure in which water does not enter from the first floor, for example, even when the first floor is flooded.
In addition, the disaster prevention storage section 17 is provided with a foldable stair ladder 172 as a lifting means, so as to enter and exit from a half-floor described later.

The protective wall PW is provided from the first floor to the upper floor in the southeastern part and the southwestern part of the building 1, respectively, and is a wall with a smaller opening provided outside than a normal outer peripheral wall provided with windows and the like. .
The protective wall PW has a structural strength as a wall body higher than other outer peripheral walls because the opening is limited to a necessary minimum such that the opening and exit and daylighting are unavoidable.
The first protection wall PW1 provided in the southwestern part of the building 1 covers three sides of the southwestern corner, and only a portion corresponding to the entrance 11 is opened.
In addition, the second protective wall PW2 provided in the southeastern part of the building 1 extends from the projecting corner of the southeastern corner to the south side along the outer edge of the main yard G.
As described above, the protective wall PW is provided in the vicinity of an opening where people enter and exit, such as the entrance 11 and the large opening 141 of the commons living 14, and, for example, a tsunami or the like rushes to the site S and collides with the building 1. In such a case, by providing the protection wall PW near the opening, the protection wall PW receives a shock to a location that may be a structural weak point of the building 1 instead.
Further, even in the case where there is a flying object such as a typhoon or a tornado, the flying object enters the building 1 due to the protection wall PW near the opening colliding with the flying object. It has become difficult.
Further, the only opening of the first protective wall PW1 corresponds to the entrance 11, and since the door 111 provided in the entrance 11 is formed using a metal plate, the structure is smaller than that of other windows. Strength is high.
For this reason, since the door 111 of the entrance 11 formed of a metal flat plate is provided in the opening of the first protective wall PW1, the structural strength is maintained higher than that of an opening such as a normal window. .

The laundry room & bathroom 35 is provided at the same height (original second floor height) as the landing 261 of the stairs 26 half a floor below. Have been. That is, there is a height difference of half a floor between the ceiling of the laundry & bathroom 35 and the ceiling of the main room 33.
The loft 334 makes it possible to effectively use the space generated by the height difference.

The laundry & bathroom 35 is provided at the southwest corner of the building 1 and is provided with a laundry 351 adjacent to the landing 261, a bathroom 352 provided on the south side of the laundry 351, and a west of the bathroom 352. And a balcony 353.
The laundry 351 is provided with a laundry pan on which a washing machine is placed and a wash basin.
The space of the laundry 351 is also used as a dressing room which is a front room of the bathroom.
Further, a balcony 353 is provided adjacent to the south side of the laundry 351 so that the washed clothes can be dried on the immediately adjacent balcony.

The atrium 37 faces the living rooms 31 and 32 and the working space 34 and has a high window 371 on the north wall. The high window 371 is openable and closable, and enables lighting, ventilation, and heat exhaust of the atrium 37.
In addition, the atrium 37 communicates with the first floor via the 1.5 floor, and the large opening 141 and the high window 371 are ventilated. Specifically, ventilation of the large opening 141 and the high window 371 allows ventilation of the space of the commons living room 14, the dining & living room 21, the kitchen 22, and the atrium 37.
For this reason, in a situation where power cannot be secured due to a power outage such as during a disaster, the air conditioner cannot be used. However, even in such a situation, by opening the high window 371, the heat inside the building 1 can be satisfactorily discharged. I can do it.
In particular, when a disaster occurs in summer, the temperature difference between the indoor and outdoor areas increases if heat cannot be exhausted. However, since the building 1 is provided with the stairwell 37 and high windows 371, the first floor It is configured to be able to consistently exhaust the heat of the space from the part to the 2.5th floor part.

Further, light windows 311 and 321 and a sliding window 341 are provided facing the atrium 37 so that the living rooms 31 and 32 and the working space 34 can be checked in status through the atrium 37, respectively.
Further, since the sliding window 341 of the working space 34 can be opened and closed, by opening this window, communication with the 1.5 floor portion can be easily performed.

[About watertight structure (airway opening / closing structure)]
The disaster prevention storage section 17 has waterproofness as described above, and the first floor portion is surrounded only by a wall having no opening or the like. In order to further enhance the waterproofness of the disaster prevention storage section 17, the building 1 has a waterproof structure in which the underfloor space U below the disaster prevention storage section 17 has a waterproof property so that water does not enter.
Specifically, as shown in FIGS. 8 and 9, the building 1 includes a foundation 4 provided on the ground and receiving the load of the building 1 (only the foundation 4 disposed below the disaster prevention storage section 17) and the foundation 4. A base packing 5 having ventilation holes 51 disposed along the outer periphery of the building 1 above the building 1, a building frame 6 for securing the structural strength of the building 1, and an outer wall finishing material 7 attached to the surface of the building frame 6. And a draining member 8 provided below the outer wall finishing material 7.
The ventilation path opening / closing structure VRS is applied to such a building 1 as a watertight structure.

The ventilation path opening / closing structure VRS includes a closing portion 9 attached to the draining member 8, a water-absorbing volume expanding material 10 provided between the closing portion 9 and the draining member 8, and an expansion of the water-absorbing volume expanding material 10. And a rising surface 1000 that comes into contact with the closing portion 9 in the case where the opening is performed.
Further, the ventilation path opening / closing structure VRS is formed with a ventilation path VR that communicates from the outside to the underfloor space U through the back surface space of the draining member 8 and the ventilation hole 51 of the foundation packing 5. In this ventilation path VR, a space AS (air space) from the back side of the drainer 8 to the outside of the base packing 5 is formed. In this space AS, a small section C (cubicle) which is inside the draining member 8 is formed.

The draining member 8 is a metal member obtained by bending a flat metal plate. At a lower end portion of the building frame 6, a fixing portion 81 abutted and fixed along the outer periphery of the building 1, and from the lower end of the building frame 6 to the outside. There is provided an extending portion 82 that extends, and a vertical portion 83 that is formed by bending vertically downward from the tip of the extending portion 82.
In addition, the draining member 8 is provided below the outer wall finishing material 7, and the extending portion 82 and the vertical portion 83 cover the space between the foundation 4 and the building frame 6 from above and from the side. When the rainwater blown to the outer wall finishing material 7 flows down along the outer wall finishing material 7, the rainwater flows to the ground along the extending portion 82 and the vertical portion 83. In addition, since the rainwater to be blown to the base packing 5 is blocked by the vertical portion 83, it is difficult for water to enter the back side of the draining member 8.

The closing portion 9 includes a mounting plate 91 attached to the back surface of the vertical portion 83 of the draining member 8, a closing plate 92 that comes into contact with the rising surface 1000 when the water-absorbing volume expansion material 10 expands, A hinge 93 for rotatably connecting the plate 91 to the plate 91.
Further, the closing portion 9 is provided such that the lower end of the mounting plate 91 is substantially at the same position as the lower end of the vertical portion 83, and a hinge 93 is provided at the lower end. One end of the closing plate 92 is attached to the hinge 93. The other end of the closing plate 92 is a free end that is not fixed to any of them. The closing plate 92 is formed with a plurality of water holes 92a.

The water-absorbing volume expanding material 10 is a long nonwoven bag body which is arranged without a break along the extending direction of the draining member 8, and swells when absorbing water to expand the water-absorbing polymer 102. The bag 101 is included.
Further, the water-absorbing volume expanding material 10 is provided with gussets (not shown) for increasing or decreasing the capacity at a plurality of places of the bag 101 containing the water-absorbing polymer 102. The gusset is designed so that when the conductive polymer 102 swells, the gusset expands to have a substantially rectangular parallelepiped shape or a substantially triangular prism shape.
In addition, the water-absorbing polymer 102 has a sustained release property, and after absorbing water, gradually releases moisture to the atmosphere, so that after the rain stops, it swells in a few days. Return.

Further, the water-absorbing volume expanding material 10 is provided with an adhesive sheet having an adhesive surface (not shown) on both surfaces of the bag 101, and one of the adhesive surfaces and the back surface of the vertical portion 83 are adhered and attached to the draining member 8. The other bonding surface and the closing plate 92 are bonded to each other and are also attached to the closing portion 9.
For this reason, when the water-absorbing volume expansion material 10 absorbs water and expands in volume, and then contracts with drying, the closing plate 92 whose other end is a free end rotates about the hinge 93 as a rotation axis. It is supposed to.
Examples of the water-absorbing polymer 102 include polyacrylate, polysulfonate, maleic anhydride, polyacrylamide, polyvinyl alcohol, polyethylene oxide, polyaspartate, polyglutamate, and polyglutamate. Alginate type, starch type, cellulose type and the like can be used.

The rising surface 1000 is a metal member obtained by bending a flat metal plate, and includes a fixed portion 1001 fixed to the upper surface of the foundation 4 along the outer periphery of the building 1, and a draining member 8 side (outside of the building 1) from the fixed portion 1001. ), And a plate receiving surface 1003 that bends from the tip of the projection 1002 toward the base packing 5 side (inside the building 1) by about 90 °.
The plate receiving surface 1003 is a surface that receives the rotating closing plate 92 when the closing plate 92 rotates and comes into contact with the rising surface 1000 when the water-absorbing volume expanding material 10 expands. When the plate receiving surface 1003 receives the closing plate 92, the closing plate 92 is received so as to protrude more toward the base packing 5 than the plate receiving surface 1003.

The angle of the plate receiving surface 1003 is set so that the entire surface of the plate receiving surface 1003 contacts the closing plate 92 when receiving the closing plate 92. That is, in the first embodiment, the plate receiving surface 1003 is bent at about 90 ° from the protruding portion 1002, but if the angle of the plate receiving surface 1003 is adjusted so that the hinge 93 is located on the extension of the plate receiving surface 1003. Well, it is not limited to 90 °.
Further, in order to increase the water stoppage between the closing plate 92 and the plate receiving surface 1003, a configuration may be adopted in which a butyl tape is attached to both or any one of the contact surfaces between the closing plate 92 and the plate receiving surface 1003.

In the ventilation path opening / closing structure VRS having the above-described configuration, when water enters the back side of the draining member 8, the infiltration path is slightly blocked by the protruding portion 1002 that protrudes upward by 45 ° outward. Then, the water that has not been completely blocked is blocked by the closing plate 92 located immediately adjacent thereto.
At this time, the blocked water passes through the water hole 92a provided in the closing plate 92 and is absorbed by the water-absorbing volume expanding material 10 arranged on the back side.
Then, the water-absorbing volume expansion material 10 absorbs water and expands, and the closing plate 92 gradually approaches the rising surface 1000, and finally the closing plate 92 comes into contact with the plate receiving surface 1003.
Thus, when there is a possibility that water may enter, the protruding portion 1002 and the closing plate 92 in the small section C block the ventilation path VR.
Thereafter, when water infiltration is eliminated, the water-absorbing volume expansion material 10 shrinks as it dries, and the closing plate 92 gradually separates from the plate receiving surface 1003, so that the ventilation path VR is opened again to allow ventilation. It will be.

In the building according to the present embodiment having the above-described configuration, the following disaster prevention measures are possible.
[First flood response]
Normally, when the inundation depth (primary inundation depth D1) under which the floor is flooded is up to about 500 mm (primary flood level), the height of the foundation 4 of the building 1 from the ground is 500 mm or more and 1000 mm or less. Since it is set arbitrarily, it does not flood under the floor.

[Secondary flood response]
In addition, when the inundation depth (secondary inundation depth D2) for inundation on the floor is usually up to about 1000 mm (secondary flood level), the foundation of the above-described building 1 is a high foundation (a height dimension from the ground of 500 mm or more). (1000 mm or less) alone cannot avoid flooding on the floor.
However, the material of the water stop plate SP is taken out from the storage bench G1, and the height from the ground is set arbitrarily within the range of 1000 mm or more and 2000 mm or less at the approach A and the opening to the approach road AR of the parking lot P. By providing the water stop plate SP, the outer periphery of the site S is surrounded by the water stop wall SW and the water stop block SB having the same height dimension from the ground as the water stop plate SP, and the water stop plate SP. Become.
For this reason, even at the secondary flood level, the provision of the water stoppage plate SP at the opening prevents water from entering the site S and prevents the building 1 from being flooded on the floor.

[Third flood damage response]
Further, when the inundation depth (tertiary inundation depth D3) far exceeding the height above the floor is up to about 2000 mm (tertiary flood damage level), the above-described water stop wall SW, water stop block SB and water stop plate SP (ground) (From 1000 mm to 2000 mm) cannot prevent water from entering the site S, and the building 1 cannot be prevented from being flooded on the floor.
However, since the building 1 is provided with a 1.5-floor floor 2 (having a height of 2000 mm or more from the ground), even if the first-floor floor 1F is flooded, the 1.5-floor floor 2 is not covered. They are not flooded.
That is, in the building 1 of the present embodiment, the dining and living room 21, the kitchen 22, the storage room 23, and the multipurpose section 24 provided on the 1.5 floor 2 are protected from flooding.
Therefore, even at the tertiary flood level, the resident can live in a space of 1.5 floors or more, and the kitchen 22 and the storage room 23 are not flooded. ing.

Further, the disaster prevention storage section 17 is a space surrounded by the storage room wall 171, and further, since the underfloor space U is prevented from entering water by the ventilation path opening / closing structure VRS, the disaster prevention storage section 17 has an opening other than the floor hatch 243. There is no.
For this reason, the disaster prevention storage section 17 is not flooded unless the 1.5 floor 2 is flooded.

Further, the multipurpose section 24 is provided with three sliding doors 241 at the opening, and the space is partitioned by closing the three sliding doors 241. For this reason, the living space can be separated from the water that has entered the building 1.
Further, since a floor hatch 243 is provided on the floor of the multipurpose section 24 as an entrance to the disaster prevention storage section 17 below, the multipurpose section 24 on the 1.5th floor is connected to the disaster prevention storage section 17 on the first floor. It is movable.
That is, even at the third flood level, the materials stored in the disaster prevention storage section 17 can be used.
Therefore, even at the tertiary flood level, the occupants can secure supplies necessary for living an evacuation life in the building 1.

Further, when evacuating from the building 1 to the outside, it is possible to evacuate with the materials stored in the disaster prevention storage section 17 and the stockpile 23.
Also, in this case, the north sliding door of the three sliding doors 241 can be opened to use the outer stairs OS adjacent to the multipurpose section 24 to go outside.

  As described above, in the present embodiment, for example, as shown in FIGS. 1, 2, 3, 6, 8, and 9, a half floor above the first floor 1F is provided above a part of the first floor 1F. 1.5 floor 2 provided between the 1.5 floor 2 and the 1st floor 1F, the disaster prevention storage section surrounded by the wall 171 and the 1st floor 1F and the half floor 2 17, a floor hatch 243 that enters and exits the disaster prevention storage section 17 provided on a part of the 1.5 floor 2 and an outdoor entrance OS1 that connects to and exits the outdoor provided on the 1.5 floor 2; Was provided.

In this way, for example, when the first floor 1F and the 1.5th floor 2 are flooded, even if the first floor 1F is flooded, the 1.5th floor 2 is prevented from being flooded. be able to.
Further, since the disaster prevention storage section 17 is closed without opening by the wall 171, the first floor 1F, and the 1.5 floor 2, the flood has been flooded up to the first floor 1F and below the 1.5 floor 2. Even so, water does not infiltrate into the disaster prevention storage section 17, and there is no danger that the stored items stored in the disaster prevention storage section 17 will be damaged by water.
In addition, since a floor hatch 243 that enters and exits the disaster prevention storage compartment 17 is provided in a part of the 1.5-floor floor 2, even if it is flooded up to the first-floor floor 1F and below the 1.5-floor floor 2, 1. It is possible to move from the fifth floor 2 to the disaster prevention storage section 17 via the floor hatch 243, and can use the disaster prevention storage section 17 even when the first floor portion is flooded.
For this reason, if emergency supplies and evacuation items are stored in the emergency storage compartment 17, the supplies in the emergency storage compartment 17 can be used in the event of a disaster. That is, the disaster prevention storage section 17 can be used as a disaster prevention storage.
In addition, since there is provided an entrance OS1 which is connected to the 1.5th floor 2 and which enters and exits the outside, the water is flooded up to the 1st floor 1F and below the 1.5th floor 2 and accused from the entrance 11. Even if it is difficult, necessary evacuation items and the like can be taken out from the disaster prevention storage compartment 17 and easily evacuated from the entrance OS1 to the outside.
Further, since the entrance OS1 is provided at the height of 1.5 floors, it is possible to evacuate to the outdoors more quickly than in the case where the entrance OS1 is provided at the second floor.
As described above, even when the building 1 is flooded, a living space and daily necessities can be secured, and when evacuating or returning home, the evacuation equipment can be easily and quickly evacuated and rescued. In some cases, you can easily enter the building.

In the present embodiment, for example, as shown in FIGS. 8 and 9, the disaster prevention storage section 17 is provided between the disaster prevention storage section 17 of the building 1 and the foundation 4 provided below the disaster prevention storage section 17. A watertight structure VRS for preventing water intrusion was provided between the base and the base 4.
This can prevent water from entering the underfloor space U of the disaster prevention storage section 17.
For this reason, when the building 1 is flooded, it is possible to more reliably prevent water from entering the disaster prevention storage section 17, and to prevent water damage to stored items in the disaster prevention storage section 17.

Further, in the present embodiment, for example, as shown in FIGS. 3 and 7, the storage 23 is provided on the 1.5 floor 2.
By doing so, for example, even if water is flooded above the first floor 1F and below the 1.5 floor 2, the storage 23 does not flood.
Therefore, when a flood is caused by flooding or the like, the stock in the stock 23 can be used.
In addition, since the disaster prevention storage section 17 and the storage 23 can be used in the event of a disaster, more supplies can be used and the inconvenience of evacuation life can be eliminated.

In the present embodiment, for example, as shown in FIGS. 3 and 7, a multi-purpose section 24 adjacent to another space on the 1.5-floor floor 2 via an opening is provided on the disaster prevention storage section 17. The multi-purpose section 24 is provided with: a 1.5-floor floor 2; a shield ceiling 245 facing the 1.5-floor floor 2; a shield wall 244 contacting the 1.5-floor floor 2 and the shield ceiling 245; The multipurpose section 24 includes an opening that opens toward another space and three sliding doors 241 that open and close the opening. When the opening is closed by the three sliding doors 241, the multipurpose compartment 24 closes to the other space. And the inside is shielded.
In this way, for example, when the first floor is flooded and evacuated on the 1.5-floor floor 2, sediment and sewage contaminants that have flowed in with the flooding approach the vicinity of the 1.5-floor floor 2. Become. Even in such a case, an evacuation life can be spent in the multipurpose section 24 on the 1.5 floor 2 and a hygienic living environment can be secured.
When the air-conditioning equipment is available in the evacuation life, the multi-purpose section 24 is a space partitioned from the other space of the normal 1.5-story floor 2, so that the air-conditioning is performed with less energy than usual. Can be. For this reason, air conditioning can be efficiently performed even in an evacuation living environment where energy use is limited.

In this embodiment, for example, as shown in FIGS. 2 and 7, openings 141, 161, 164, and 165 are respectively provided on a plurality of opposing walls on the first floor of the building 1 so as to oppose each other. Was formed.
In this way, the water that has entered the building 1 can be discharged from the openings 141 and 164 to the outside.
In addition, openings 141, 161, 164, and 165 are formed on each of a plurality of opposing walls on the first floor of the building 1 so as to oppose each other. When water flows into a building, water flowing from one outdoor can be smoothly drained to the other outdoor through a plurality of openings 141, 161, 164, and 165.
For this reason, it is possible to eliminate the possibility that water stays in the building 1 and the water level inside the building becomes higher than that outside, and the water is flooded on the 1.5 floor 2 as much as possible. Can be prevented.

In the present embodiment, for example, as shown in FIGS. 2, 3, and 7, the multipurpose section 24 is provided above the disaster prevention storage section 17, and the storage room wall 171 surrounding four sides of the disaster prevention storage section 17 is provided. , And the shielding wall 244 are arranged on the same plane.
In this way, the disaster prevention storage section 17 and the multipurpose section 24 can be made to have a robust structure, and safety can be ensured by evacuating to this space in the event of a disaster.

Further, in the present embodiment, for example, as shown in FIGS. 2, 3, and 7, the disaster prevention storage section 17 and the multipurpose section 24 are integrally formed, and the first floor 1F to the 2.5 floor The space up to three heights is divided by the 1.5-floor floor 2, the lower part is a disaster prevention storage section 17, and the upper part is a multipurpose section 24.
In this way, when evacuating to the multipurpose section 24 at the time of a disaster, the disaster prevention storage section 17 below can be used, and an evacuation life can be performed while utilizing the disaster prevention materials in the disaster prevention storage section 17.

In the present embodiment, for example, as shown in FIGS. 3 and 4, the kitchen 22 is provided on the 1.5th floor 2, and the landing 261 of the stairs 26 having the second floor height has a laundry & bathroom. 35 and a toilet 38 are provided.
By doing so, for example, even when the building 1 is flooded to the first floor 1F, the multi-purpose section 24, the storage 23, the kitchen 22, the laundry & bathroom 35 And the toilet 38 do not need to be flooded.
Therefore, even in the event of a flood, facilities necessary for living in the building 1 can be used, and the resident can maintain a cultural living environment even in evacuation.

Further, in the present embodiment, for example, as shown in FIG. 3, the dining and living room 21 is provided with a transparent handrail 213 made of glass at the edge (south end) of the 1.5 floor 2.
By doing so, it is possible to provide a space where a feeling of openness can be felt from the dining & living 21 to the main garden G via the commons living 14 and the large opening 141.
In addition, even in the event of a disaster, the situation to the outdoors can be seen, so that the situation of the outdoors and the situation of the resident indoors can be quickly checked.

In the present embodiment, for example, as shown in FIGS. 4 and 6, the living rooms 31 and 32 and the working space 34 have light windows 311 and 321 facing the atrium 37 communicating with the 1.5-floor portion, and a drawer. A window 341 was provided so that the 1.5th floor could be viewed.
By doing so, it is possible to confirm the status of the 1.5 floor portion from the living rooms 31, 32 and the working space. Conversely, the status of the living rooms 31, 32 and the working space 34 can be confirmed from the 1.5 floor portion. In addition, the status of each of the living rooms 31 and 32 and the working space 34 can be confirmed through the light windows 311 and 321 and the sliding window 341.
Therefore, for example, when the living rooms 31 and 32 are used as children's rooms, the guardian can check the state of the child's room from the 1.5 floor portion and the working space 34.
Also, in the event of a disaster, if the guardian is on the 2.5th floor, simply move to the passage 36 and check the status of the children in the living room from the sliding window 341 of the working space 34. it can. In addition, when the guardian is on the 1.5 floor portion, the state of the 2.5 floor can be seen through the stairwell 37.
Further, since the window of the working space 34 is a sliding window 341, opening the sliding window 341 allows the working space 34 to communicate with the atrium 37. As compared with the living rooms 31 and 32, It is possible to more easily and surely check the status of the 1.5-floor portion and the living rooms 31 and 32 and to communicate.

In the present embodiment, for example, as shown in FIG. 6, the stairwell 37 communicates with the first floor via the 1.5 floor, and includes a high opening / closing window 371 on the north wall. It was taken.
By doing so, the large opening 141 and the high window 371 can be ventilated, and the space between the commons living room 14, the dining & living room 21, the kitchen 22, and the atrium 37 can be ventilated.
For this reason, in a situation where power cannot be secured due to a power outage such as during a disaster, the air conditioner cannot be used. However, even in such a situation, by opening the high window 371, the heat inside the building 1 can be satisfactorily discharged. it can.
In particular, when a disaster occurs in summer, the temperature difference between the indoor and outdoor areas increases if heat cannot be exhausted. However, since the building 1 is provided with the stairwell 37 and high windows 371, the first floor The heat of the space from the part to the 2.5th floor part can be exhausted consistently.

In the present embodiment, for example, as shown in FIG. 4, the laundry 351 and the balcony 353 are provided adjacent to each other.
By doing so, the clothes washed by the washing machine arranged on the laundry pan can be dried on the adjacent balcony.
Therefore, there is no need to move the laundry, and the laundry can be immediately dried from the washing machine, and the work load can be reduced.

In the present embodiment, for example, as shown in FIGS. 5 and 6, a loft 334 is provided on the west side of the main room 33, and an opening is provided as an entrance to and from the loft 334.
By doing so, not only the walk-in closet 331 but also the loft 334 can be used as a storage space for the main room 33.
Further, the space generated between the ceiling of the laundry & bathroom 35 and the ceiling of the main room 33 can be effectively used.

In the present embodiment, for example, as shown in FIG. 2, the waterproof sheet 112 is attached to the south side of the door 111 of the entrance 11, and the waterproof sheet 112 is attached to the opposing side wall.
This prevents the waterproof sheet 112 from interfering with the outwardly-opening door 111 and allows the outwardly-opening door 111 to be opened and closed even when the waterproof sheet 112 is attached.

Further, in the present embodiment, for example, as shown in FIG. 2, it is assumed that a storage bench G <b> 1 of the main yard G stores tools necessary for cooking such as a furnace.
By doing so, at the time of a disaster such as an earthquake, these can be taken out and cooked in the main garden G.
For this reason, it is possible to cook and eat in a large space where the main garden G and the commons living 14 communicate with each other through the large opening 141 of the commons living 14 adjacent to the main garden G.

In the present embodiment, for example, as shown in FIGS. 1 and 2, a protective wall PW is provided in the southeastern part and the southwestern part of the building 1 from the first floor to the upper floor, and a window is provided. It is a wall provided with a smaller opening provided outside than a normal outer peripheral wall.
For this reason, since the opening of the protective wall PW is limited to a necessary minimum, the structural strength as a wall can be increased as compared with other outer walls.
Further, since the protective wall PW is provided outside the normal outer peripheral wall, even if the protective wall PW receives an impact such as a flying object or a tsunami, the impact can not be directly transmitted to the building 1.

Further, in the present embodiment, for example, as shown in FIGS. 1 and 2, the protective wall PW is provided near an opening where people enter and exit, such as the entrance 11 and the large opening 141 of the commons living 14.
By doing so, for example, when a tsunami or the like rushes to the site S and collides with the building 1, the protective wall PW is provided near the opening, so that the impact on the location that may be a structural weak point of the building 1 Is received by the protective wall PW instead.
Further, even in the case where there is a flying object such as a typhoon or a tornado, the flying object enters the building 1 due to the protection wall PW near the opening colliding with the flying object. It has become difficult.

As described above, the present invention has been specifically described based on the embodiment. However, the present invention is not limited to the above embodiment, and can be changed without departing from the gist of the invention.
In the present embodiment, the ventilation path opening / closing structure VRS is used as the watertight structure. However, the present invention is not limited to this. For example, as shown in FIG. Any configuration may be used as long as water does not enter the underfloor space U of the disaster prevention storage section 17.
Further, with such a configuration, it is only necessary to perform caulking on the outdoor side of the basic packing 5, a watertight structure can be provided by simple construction, and the cost can be reduced.

Further, in addition to caulking the base packing 5, a waterproof sheet may be stretched from outside the base packing 5. Specifically, a configuration in which the base 4 and the lower part of the building frame 6 are stretched with a waterproof sheet is preferable.
This not only prevents water from entering the underfloor space U, but also prevents the lower part of the building frame 6 from being flooded.
For this reason, when the building frame is a wooden member, it is possible to prevent the wood from being deformed and, if it is a metal, to prevent corrosion.
