  By the way, in recent years, flood damage such as a tsunami caused by an earthquake or a flood caused by heavy rain has occurred. In this case, buildings with reinforced concrete structures such as condominiums have structures that are less likely to be swept away by tsunamis and floods than wooden buildings, but because the top of the balcony is open to the outside, It was difficult to prevent water from flowing into the room from the opening on the balcony side.

  The present invention has been made in view of the above-described problems, and the object of the present invention is to prevent water from flowing into the room from the balcony-side opening even in the event of a flood that causes the building to be submerged. The purpose is to provide a balcony structure for the building.

  In order to achieve the above object, the present invention provides a balcony structure of a building having an opening that leads from the indoor side to the balcony and a ceiling for a balcony provided above the opening. A balcony main body that is movably provided and has a balcony floor and a wall, and a rising means for raising the balcony main body. When the balcony main body is raised by the raising means, the opening is formed by the balcony main body and the ceiling portion. It is configured to be closed.

  As a result, in the event of a flood that causes the building to be submerged, such as a tsunami due to an earthquake or a flood due to heavy rain, if the balcony body is lifted by the lifting means, the opening of the building body will be closed by the balcony body and the ceiling. Thus, the intrusion of water from the opening into the room is prevented by the balcony body.

  According to the present invention, even when a flood such as a tsunami caused by an earthquake or a flood due to heavy rain occurs that causes the building to be submerged, it is possible to prevent the intrusion of water into the room by raising the balcony body. This can prevent indoor damage caused by flooding.

  The building body 10 has an opening 11 that leads from the room 10a side to the balcony 20 side, and the opening 11 is opened and closed by a sliding door 12 made of a glass door. The building body 10 is provided with a ridge 13 protruding above the balcony 20, and the ridge 13 forms the ceiling of the balcony 20. Further, a sealing material 14 extending along the front end side and the width direction both end sides is provided on the lower surface of the flange 13.

  The balcony 20 has a balcony main body 21 formed so as to protrude from the building main body 10, a pair of left and right support mechanisms 22 that support the balcony main body 21 movably in the vertical direction on the building main body 10, and the balcony main body 21 has buoyancy. A buoyancy member 23 to be applied, and the buoyancy member 23 serves as a raising means for raising the balcony main body 21.

  The balcony main body 21 rises from the front end side of the floor portion 21a and both ends in the width direction so as to form the floor portion 21a formed to have the same width and depth dimensions as the ridge 13 and the front and left and right side surfaces of the balcony main body 21. It consists of a wall portion 21b and an extending portion 21c that extends downward in a plate shape along the outer surface of the building body 10 from the rear end side of the floor portion 21a. The floor portion 21a, the wall portion 21b, and the extending portion 21c are lightweight. They are integrally formed with each other by members having high strength. Moreover, the sealing material 24 extended in the width direction of the extension part 21c is provided in the lower end side of the back surface of the extension part 21c, and the sealing material 24 is formed over substantially the full width of the extension part 21c. Further, the balcony main body 21 is restricted from moving downward when the lower end of the extending portion 21 c comes into contact with the stopper portion 15 protruding from the outer surface of the building main body 10.

  Each support mechanism 22 includes a fixed rail 22a attached to the building body 10 side and a movable rail 22b attached to the balcony body 21 side. The fixed rail 22a and the movable rail member 22b slide in the vertical direction. Engage freely. In this case, a well-known slide rail can be used for the support mechanism 22, and the fixed rail 22a and the movable rail member 22b are sealed with a sealing material (not shown). The movable rail member 22b is disposed on the rear end surfaces of the left and right wall portions 21b, and is formed from the upper end of the wall portion 21b to the lower end of the extending portion 21c.

  The buoyancy member 23 is a hollow member provided below the floor portion 21a of the balcony main body 21, and is fixed to the lower surface of the floor portion 21a and the front surface of the extension portion 21c. In this case, the buoyancy member 23 is formed in a rectangular parallelepiped shape having a width dimension and a depth dimension equivalent to the floor portion 21a of the balcony main body 21, and having a height dimension equivalent to the extension portion 21c, and the internal space is hermetically sealed. It is made of a lightweight and high strength member.

  In the above configuration, as shown in FIGS. 2, 3 and 4, the balcony main body 21 comes into contact with the stopper 15 of the building main body 10, so that the balcony main body 21 is in a normal height position. That is, at this normal height position, the space between the wall portion 21b of the balcony main body 21 and the eaves 13 is opened, and the balcony main body 21 side can be entered and exited through the opening portion 11 from the indoor 10a side.

  Here, in the event of a flood that causes the building 1 to be submerged, such as a tsunami due to an earthquake or a flood due to heavy rain, when the water level of the tsunami or flood reaches the balcony 20, buoyancy as shown in FIGS. The balcony main body 21 is lifted by the buoyancy of the member 23, and the opening 11 of the building main body 10 is closed by the balcony main body 21. That is, as the balcony main body 21 rises, the upper end of the wall portion 21b comes into contact with the lower surface of the ridge 13 through the sealing material 14, and the substantially upper half of the opening 11 is the ridge 13, the floor portion 21a of the balcony main body 21, and the wall portion. 21 b and substantially the lower half of the opening 11 is covered by the extension 21 c of the balcony main body 21. At that time, the space between the balcony main body 21 and the building main body 10 is sealed by the sealing material 14 of the eaves 13, the rails 22a and 22b of the support mechanism 22, and the sealing material 24 of the extending portion 21c. Accordingly, the balcony main body 21 prevents water from entering the room 10a due to a tsunami or flood. Further, when the tsunami or flood is resolved, the balcony main body 21 descends as the water level falls, and returns to the normal height position by contacting the stopper portion 15.

  Thus, according to the balcony structure of this embodiment, the balcony main body 21 having the floor 21a and the wall 21b of the balcony 20 is provided on the building main body 10 so as to be movable in the vertical direction, and the balcony main body 21 is raised. Since the opening 11 of the building main body 10 is closed by the balcony main body 21 and the balcony wall 13, the balcony 1 can be used even when a flood such as a tsunami caused by an earthquake or a flood due to heavy rain occurs that causes the building 1 to be submerged. By raising the main body 21, water can be prevented from entering the room 10 a by the balcony main body 21, and damage to the room 10 a due to flooding can be prevented.

  In this case, when the water level of the tsunami or flood reaches the balcony 20, the balcony main body 21 is raised by buoyancy, so that a separate driving force for raising the balcony main body 21 is not required, and with the arrival of the tsunami or flood The balcony main body 21 can be raised reliably.

  Moreover, since the buoyancy is given to the balcony main body 21 by the buoyancy member 23 provided on the balcony main body 21, the buoyancy can be reliably given to the balcony main body 21, and the opening 11 of the building main body 10 is connected to the balcony main body 21. Can be closed quickly.

  That is, the balcony 20 of the present embodiment includes an airbag 26 as a raising unit that imparts buoyancy to the balcony body 25 in place of the buoyancy member 23 of the first embodiment. An inflator 27 as an expansion means for expanding the water and a float switch 28 as a water detection means for detecting water at a predetermined water level or higher are provided.

  The airbag 26 is formed into a bag shape by a flexible cloth having high airtightness and durability, and is inflated by filling the inside with air. The airbag 26 is folded in a contracted state and is installed on the lower surface of the floor portion 21a.

  The inflator 27 has a known configuration in which, for example, a cylinder filled with a compressed fluid is opened by explosive explosives or a puncture of a shooting needle, and is connected to an airbag 26.

  The float switch 28 is a well-known device that is turned on when the float moves upward to a predetermined position due to a rise in water level, and is connected to the inflator 27. In this case, the float switch 28 is disposed below the airbag 26 in a contracted state, and operates when the water level that has arrived due to a tsunami or flood is equal to or higher than a predetermined water level (for example, a position directly below the floor portion 21a). It has become.

  In the above configuration, in the event of a flood that causes the building 1 to be submerged, such as a tsunami caused by an earthquake or a flood due to heavy rain, the water level of the tsunami or flood reaches below the balcony 20 and the float switch 28 is turned on. 11, the airbag 26 is inflated by the inflator 27, and the balcony main body 21 is raised by the buoyancy of the airbag 26. As a result, as in the first embodiment, the opening 11 of the building body 10 is closed by the balcony body 21, and water intrusion into the room 10 a due to a tsunami or flood is prevented by the balcony body 21.

  Thus, according to the balcony structure of this embodiment, the balcony main body 21 that can move in the vertical direction and the airbag 26 that imparts buoyancy to the balcony main body 21 are provided, and the water level of tsunami and flood reaches the balcony 20. Then, the airbag 26 is inflated, the balcony main body 21 is raised by the buoyancy of the airbag 26, and the opening 11 of the building main body 10 is closed by the balcony main body 21. Thus, as in the first embodiment, the earthquake Even in the event of a flood that causes the building 1 to be submerged, such as a tsunami caused by a heavy rain or a heavy rain, the balcony main body 21 can prevent water from entering the room 10a and prevent damage to the room 10a due to flooding. Can do.

  In each of the above embodiments, the balcony main body 21 is raised by buoyancy. However, a lifting means for raising the balcony main body 21 by power such as hydraulic pressure or a motor may be used. In this case, the rising means may be activated when the water level is detected by the water detecting means as in the second embodiment, but the raising means is activated by operating the switch. May be. When the raising means is operated by the switch, the balcony main body 21 can be arbitrarily raised, so that the opening 11 of the building main body 10 can be opened by the balcony main body 21 even during disasters other than tsunamis and floods such as typhoons and tornadoes. Can be closed.
