Description

[Technical Field]

[0001] The present disclosure relates to an exterior wall unit equipped with life-saving equipment, an exterior wall with equipment attachment, and a building. [Background technology]

[0002] Buildings equipped with lifesaving equipment for saving lives during floods or inundation are known (for example, Patent Document 1). The building described in Patent Document 1 has bay windows. The bay windows are configured to be usable as lifeboats in emergencies. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 10-258795 Summary of the Invention [Problem to be solved by the invention]

[0004] According to the technology of Patent Document 1, bay windows are used as lifeboats, so the interior space is not narrowed by the life-saving equipment. However, this technology requires bay windows in buildings to accommodate the life-saving equipment. Therefore, when installing life-saving equipment, the flexibility of the exterior design of the building is limited. It is desirable that the flexibility of the exterior design of buildings in which life-saving equipment is installed is not limited. [Means for solving the problem]

[0005] (1) An exterior wall unit that solves the above problem comprises a wall main body having an opening and a wall panel that closes the opening, the wall panel being configured to allow life-saving equipment to be placed on the wall main body and being openable and closable.

[0006] According to this configuration, when an exterior wall attached to equipment is constructed using exterior wall units, life-saving equipment can be placed near the wall panels. Therefore, at least a part of the life-saving equipment can be placed inside the exterior wall attached to equipment. This makes it difficult for the life-saving equipment to jump out of the room. Therefore, in a building where such life-saving equipment is installed, restrictions on the freedom of the building's exterior design can be suppressed.

[0007] (2) In the exterior wall unit described in (1) above, at least a portion of the gap between the opening and the wall panel is sealed with a sealant. This configuration makes it possible to prevent water from entering between the opening and the wall panel.

[0008] (3) The exterior wall unit according to (2) above further comprises a cutting device for cutting the sealant. With this configuration, the sealant can be cut by the cutting device, which makes it easier to open the wall panel.

[0009] (4) An exterior wall with attached equipment that solves the above problem comprises a wall body having an opening, a wall panel that closes the opening, and life-saving equipment that is placed on the wall panel in a folded state, the wall panel being configured so that the life-saving equipment can be placed on the wall body and being openable and closable, and at least a portion of the gap between the opening and the wall panel being sealed with a sealant.

[0010] This configuration allows the life-saving equipment to be placed near the wall panel in the exterior wall attached to the equipment. Therefore, at least a portion of the life-saving equipment can be placed inside the exterior wall attached to the equipment. This makes it difficult for the life-saving equipment to jump out of the room. Therefore, in buildings where such life-saving equipment is installed, restrictions on the freedom of the building's exterior design can be suppressed. Furthermore, water infiltration between the opening and the wall panel can be suppressed.

[0011] (5) The exterior wall attached to facilities described in (4) above further comprises a cutting device for cutting the sealant. With this configuration, the sealant can be cut by the cutting device, which makes it easier to open the wall panel.

[0012] (6) In the exterior wall attached to facilities described in (5) above, the cutting device includes a cutter configured to follow the sealant and a drive unit that moves the cutter. With this configuration, the sealant can be cut by the cutter.

[0013] (7) In the exterior wall attached to equipment described in (6) above, the drive unit operates to move the cutter toward the sealant. According to this configuration, the cutter can be moved toward the sealant by the operation of the drive unit.

[0014] (8) In the outer wall attached to the facility described in (7) above, the cutter has a blade and a pressing part that supports the blade and receives pressure, the drive part has a case and a bag that is arranged in the case and inflates with gas, and the pressing part is arranged in the case so as to receive pressure from the bag when the bag inflates. With this configuration, the cutter can be moved by supplying gas.

[0015] (9) In the exterior wall attached to the facility described in any one of (4) to (8) above, the life-saving equipment is a lifeboat that is inflated with gas, and the lifeboat is placed in the center of the opening in a deflated and folded state. With this configuration, the wall panel can be opened by the inflation of the lifeboat.

[0016] (10) The outer wall attached to the facility described in (9) above further comprises a gas supply device for supplying gas to the lifeboat and the cutting device. With this configuration, since the gas supply device is provided on the outer wall attached to the facility, the lifeboat can be inflated immediately in an emergency.

[0017] (11) The outer wall attached to the facility described in (10) above further comprises an operating unit for starting the supply of gas from the gas supply device to the lifeboat and the cutting device. With this configuration, the gas supply to the lifeboat and the cutting device can be started by operating the operating unit.

[0018] (12) In the external wall attached to the facility described in (9) above, the lifeboat is connected to the wall main body by a rope, and the rope is configured to be detachable from the wall main body or the lifeboat. With this configuration, the lifeboat is connected to the wall main body or wall panel by the rope, so that it is possible to prevent the lifeboat from drifting away. Furthermore, because the rope is configured to be detachable from the wall main body or the lifeboat, the engagement between the external wall attached to the facility and the lifeboat can be released when necessary, and the lifeboat can be separated from the external wall attached to the facility.

[0019] (13) A building that solves the above problem includes an exterior wall with equipment attachment according to any one of (4) to (12). This configuration can prevent restrictions on the freedom of the building's exterior appearance. It can also prevent water from seeping in between the opening and the wall panel.

[0020] (14) The building described in (13) above has two or more floors, and the exterior wall attached to the equipment is installed between the bottom edge of the window and the floor in the vertical direction on the second or higher floors. With this configuration, life-saving equipment can be brought out from the opening below the window on the second or higher floors. Then, people can get out of the window and move to the life-saving equipment. [Effects of the Invention]

[0021] According to the exterior wall unit, exterior wall with equipment attachment, and building disclosed herein, in a building equipped with life-saving equipment, restrictions on the freedom of the building's exterior appearance can be reduced. [Brief explanation of the drawings]

[0050] 11, when the bag 39 expands, the bag 39 presses the pressing portion 33 of the cutter 31. This causes the cutter 31 to move toward the notch 17 of the wall panel 16. This causes the blade portion 32 to be inserted into the sealant 19. This causes the sealant 19 to be cut.

[0051] [Lifesaving equipment] As shown in Figures 5 and 6, the life-saving equipment 40 is arranged between the outer wall unit 11 and the inner wall board 18. The life-saving equipment 40 is arranged in a folded state in the wall panel 16. The life-saving equipment 40 is a lifeboat 41 that is inflated with gas. The lifeboat 41 is made of a resin sheet. The lifeboat 41 is arranged in the center of the wall panel 16 in a deflated and folded state (see Figure 3). The lifeboat 41 is folded so as to be folded along multiple folds extending in the horizontal direction. The horizontal direction is the direction along the upper surface 14A of the opening 14.

[0052] 12 and 13, the lifeboat 41 is connected to the wall main body 13 by a rope 42. The rope 42 is configured to be detachable from the wall main body 13 or the lifeboat 41. The rope 42 connects the lifeboat 41 to a bracket 21 attached to the upper part of the wall main body 13.

[0053] The lifeboat 41 is connected to the gas supply device 45 by a second tube 54. Gas is supplied to the lifeboat 41 from the gas supply device 45 via the second tube 54. The second tube 54 is detached from the lifeboat 41 when the lifeboat 41 has completed inflation.

[0054] [Gas supply equipment] The gas supply device 45 is disposed between the outer wall unit 11 and the inner wall board 18. The gas supply device 45 is disposed on top of the life-saving equipment 40. The gas supply device 45 supplies gas to the lifeboat 41 and the cutting device 30. The gas supply device 45 includes a cylinder 46 filled with gas. The cylinder 46 is filled with gas at a pressure higher than atmospheric pressure. Examples of gas include air, inert gas, nitrogen, carbon dioxide, and mixtures thereof.

[0055] The gas supply device 45 may supply gas by generating gas. The gas supply device 45 may have a gas generating unit. The gas generating unit generates gas by burning a gas generating agent.

[0056] The gas supply device 45 supplies gas to the bag 39 of the cutting device 30 via a first tube 53. The gas supply device 45 supplies gas to the lifeboat 41 via a second tube 54. The gas supply device 45 has a first valve (not shown) and a second valve (not shown). The first valve is provided between the cylinder 46 and the first tube 53. Before the first operating unit 51 is operated, the first valve is closed. The second valve is provided between the cylinder 46 and the second tube 54. Before the second operating unit 52 is operated, the second valve is closed.

[0057] [Operation section] The operating unit 50 is attached to the wall main body 13 so that a portion of the operating unit 50 is exposed to the interior of the room from the interior wall board 18. The operating unit 50 starts the supply of gas from the gas supply device 45 to the lifeboat 41 and the cutting device 30.

[0058] The operating unit 50 has a first operating unit 51 that opens the first valve. When the first operating unit 51 is operated, the first valve opens. When the first valve opens, gas is supplied to the bag 39 of the cutting device 30 via a first tube 53.

[0059] The operating unit 50 has a second operating unit 52 that opens the second valve. When the second operating unit 52 is operated, the second valve opens. When the second valve opens, gas is supplied to the lifeboat 41 via a second tube 54.

[0060] [Operation of exterior walls attached to facilities] The operation of the external wall attached to facilities 10 will be described with reference to FIGS. The life-saving equipment 40 is used during heavy rain, floods, or tsunamis. For example, when water rises close to the bottom of the outer wall 10 attached to the equipment, the lifeboat 41 is launched. At this time, the operating unit 50 is pressed. After operating the first operating unit 51, the second operating unit is operated.

[0061] When the first operating part 51 is operated, the first valve opens. This supplies gas to the bag 39 of the cutting device 30. When the bag 39 expands with the gas, the bag 39 presses the pressing part 33. This moves the cutter 31, and the blade part 32 comes out of the case 37. When the blade part 32 comes out of the case 37, the blade part 32 cuts the sealant 19. This makes it possible to open the wall panel 16.

[0062] When the second operating unit 52 is operated, the second valve opens. This supplies gas to the lifeboat 41. When the lifeboat 41 is inflated by the gas, it pushes against the wall panel 16. This causes the wall panel 16 to open. As the wall panel 16 opens, part of the lifeboat 41 comes out through the opening 14 in the wall main body 13. When the wall panel 16 opens further, the entire lifeboat 41 comes out of the wall main body 13. Because the lifeboat 41 is connected to the wall main body 13 by the rope 42, the lifeboat 41 does not move away from the window 3. People can board the lifeboat 41 through the window 3.

[0063] [Operation of this embodiment] The exterior wall unit 11 comprises a wall main body 13 having an opening 14, and a wall panel 16 that closes the opening 14. The wall panel 16 is attached to the wall main body 13 so as to be able to open and close. The wall panel 16 is configured so that life-saving equipment 40 can be placed thereon. With this configuration, the life-saving equipment 40 can be placed inside the equipment-attached exterior wall 10. Therefore, since the life-saving equipment 40 is not placed outside, there is no need to consider the placement of the life-saving equipment 40 in the design of the exterior of the building 1. In this way, restrictions on the degree of freedom in the exterior of the building 1 can be suppressed. Furthermore, the life-saving equipment 40 can be placed on the indoor-facing surface of the wall panel 16. This allows the life-saving equipment 40 to be easily taken out through the opening 14 of the wall main body 13.

[0064] [Effects of this embodiment] (1) The exterior wall unit 11 includes a wall main body 13 having an opening 14, and a wall panel 16 that closes the opening 14. The wall panel 16 is configured to allow life-saving equipment 40 to be placed thereon, and is attached to the wall main body 13 so as to be openable and closable.

[0065] According to this configuration, when the equipment-attached exterior wall 10 is formed by the exterior wall units 11, the life-saving equipment 40 can be placed near the wall panels 16. Therefore, at least a part of the life-saving equipment 40 can be placed inside the equipment-attached exterior wall 10. This makes it difficult for the life-saving equipment 40 to jump out of the room. Therefore, in a building 1 in which such life-saving equipment 40 is installed, it is possible to suppress restrictions on the degree of freedom in the exterior design of the building 1.

[0066] (2) At least a portion of the gap between the opening 14 and the wall panel 16 is sealed with the sealant 19. This configuration makes it possible to prevent water from entering between the opening 14 and the wall panel 16.

[0067] (3) The exterior wall unit 11 may further include a cutting device 30 that cuts the sealant 19. According to this configuration, the sealant 19 can be cut by the cutting device 30. This makes it easier to open the wall panel 16.

[0068] (4) The equipment-attached exterior wall 10 comprises a wall body 13, a wall panel 16, and life-saving equipment 40. The wall panel 16 is configured so that the life-saving equipment 40 can be placed thereon, and is provided on the wall body 13 so as to be openable and closable. At least a portion of the gap between the opening 14 and the wall panel 16 is sealed with a sealant 19.

[0069] According to this configuration, the life-saving equipment 40 can be arranged near the wall panel 16 in the equipment-attached exterior wall 10. Therefore, at least a part of the life-saving equipment 40 can be arranged inside the equipment-attached exterior wall 10. This makes it difficult for the life-saving equipment 40 to jump out of the room. Therefore, in a building 1 in which such life-saving equipment 40 is installed, restrictions on the degree of freedom in the exterior design of the building 1 can be suppressed. Furthermore, water infiltration between the opening 14 and the wall panel 16 can be suppressed.

[0070] In this embodiment, in the equipment-attached exterior wall 10, the life-saving equipment 40 is arranged between the exterior wall unit 11, which includes the wall body 13 and the wall panel 16, and the interior wall board 18. In other words, the life-saving equipment 40 is housed within the equipment-attached exterior wall 10.
