Description

  The present invention relates to a building and a building design apparatus.

  A building such as a house may be provided with a sprinkler facility as a fire extinguishing facility. In this case, when a fire occurs, it can be extinguished by water discharge from the sprinkler facility. However, when fire extinguishing is performed by water discharge, although the fire can be extinguished, water damage occurs in which the building itself, building facilities, office supplies, furniture, etc. get wet or break due to water pressure. In addition, even if fire extinguishing equipment that discharges powder or foam extinguishers in place of water is installed in the building, the powder itself or foam extinguishing agent may cause contamination of the building itself or building equipment, etc. End up.

On the other hand, in order to suppress the occurrence of the above-described water damage and pollution, a technique has been proposed in which fire extinguishing is performed by a fire extinguishing facility that emits a fire extinguishing gas. For example, Patent Document 1 discloses a configuration in which carbon dioxide gas is released into a protective compartment when a fire occurs in the protective compartment. With this configuration, fire extinguishing can be performed without causing water damage or fouling. In addition, since carbon dioxide gas is released into the protective compartment only when the protective compartment is in an unattended state, it is possible to prevent a person from inhaling the carbon dioxide gas. Therefore, human damage caused by carbon dioxide gas does not occur.
Japanese Patent Laid-Open No. 5-261164

  However, in the configuration described in Patent Document 1, fire extinguishing is performed using carbon dioxide gas as a fire extinguishing gas only when the protective section is in an unattended state, which may adversely affect the human body. While being avoided, initial fire fighting may be delayed. This is because when there is a person in the protective zone, even if a fire occurs, the fire extinguishing gas is not released into the protective zone, and for example, initial fire extinguishing cannot be performed until a person leaves the protective zone. Therefore, there is room for improvement in a configuration in which fire extinguishing gas is extinguished while ensuring human safety.

  The main object of the present invention is to improve human safety while suitably performing initial fire extinguishing in a configuration in which fire extinguishing is performed with a fire extinguishing gas.

  In order to solve the above-mentioned problem, the first invention extinguishes a fire detection means for detecting the occurrence of a fire, a person detection means for detecting the presence of a person, and a gas discharge section for releasing a fire extinguishing gas heavier than air. The building is equipped with control means for releasing a fire extinguishing gas from the gas discharge unit in accordance with the detection result of the human detection means when a fire occurrence is detected by the fire detection means. The fire extinguishing equipment is installed in a fire extinguishing section that is a predetermined indoor space section partitioned by walls, and the gas discharge section is installed on or near the floor surface in the fire extinguishing section. Features.

  According to the first invention, when a fire occurs in the fire extinguishing section, the fire extinguishing gas is released in accordance with the detection of the fire, so that the initial fire extinguishing can be quickly performed in the fire extinguishing section. In addition, the fire-extinguishing section is defined in an indoor space sectioned by walls, and since the flow of the fire-extinguishing gas is restricted, it is avoided that the fire-extinguishing gas flows out and the fire-extinguishing gas extinguishing capability is reduced. It can be demonstrated continuously. Therefore, it is possible to exert a deterrent against the fire spreading from the fire extinguishing section to other areas. Moreover, in the fire extinguishing section, fire extinguishing gas heavier than air is released near the floor surface, so that the fire extinguishing gas is easily stored under the air layer without mixing with air. Therefore, for example, when there is a fire source in the vicinity of the floor, the fire can be extinguished particularly effectively, and even if there is a person in the fire extinguishing section, the person can breathe safely without inhaling the fire extinguishing gas.

  As a result, in the configuration in which the fire is extinguished by the fire extinguishing gas, it is possible to improve human safety while suitably performing the initial fire extinguishing.

  In addition, it is preferable that the fire extinguishing gas discharge | released from the said gas discharge | release part is a carbon dioxide gas (carbon dioxide). Carbon dioxide adversely affects the human body when it is inhaled by humans, but combustion does not occur in a dense space. Therefore, it is preferable that carbon dioxide is applied to the fire extinguishing gas in a configuration that can prevent a person from inhaling the fire extinguishing gas.

  Moreover, it is preferable that the alarm apparatus which issues an alarm according to discharge | release of the fire-extinguishing gas from the said gas discharge part is provided. In this case, since the person can recognize that the fire-extinguishing gas is released into the fire-extinguishing section, the safety of the person can be further enhanced when the fire-extinguishing gas is released.

  According to a second aspect of the present invention, an operation unit that allows the fire extinguishing gas to be released by being operated by a person is provided, and the control unit detects the occurrence of a fire by the fire detection unit. If the presence of a person is detected and the operation unit is not in a gas discharge permitting state, the extinguishing gas is not released from the gas discharge unit, and even if the presence of a person is detected, the operation unit is in the permitting state. Fire extinguishing gas is released from the gas discharge part.

  According to the second invention, when there is a person in the fire extinguishing section, the operation unit needs to be operated to release the fire extinguishing gas. In this case, it is possible to prevent the fire extinguishing gas from being unexpectedly released for a person in the fire extinguishing section, so that the possibility of accidentally inhaling the fire extinguishing gas when a fire occurs can be further reduced.

  In addition, it is preferable that the operation part is provided in the fire extinguishing section. This is because the person who is in the fire zone can make the most appropriate decision regarding the release of fire gas.

  In 3rd invention, it is provided in the said fire extinguishing division or the boundary part of several fire extinguishing divisions so that it can appear and disappear, and it has the partition body which controls the outflow of the said fire extinguishing gas, allowing a person to pass in the appearance state. .

  According to the third invention, when the fire extinguishing section is partitioned into a plurality of parts by the partition body, the fire extinguishing gas can be stored in the predetermined part in the fire extinguishing section, while the person has the predetermined part and the other part in the fire extinguishing section. You can go back and forth. In addition, when a predetermined fire extinguishing compartment and another fire extinguishing compartment are separated by a partition body, the fire extinguishing gas is restricted from flowing out from the predetermined fire extinguishing compartment to other fire extinguishing compartments. You can go back and forth. Therefore, when a fire occurs in the fire extinguishing section, it is possible to easily evacuate a person from the fire extinguishing section while suitably performing fire extinguishing with the extinguishing gas.

  In addition, as the “partition body that restricts the outflow of the fire extinguishing gas while allowing the passage of a person”, a partition body having a configuration that is fragile when a person passes through the boundary part of the fire extinguishing section, or a person also passes through Examples include a partition having a configuration that easily deforms, and a partition having a height that can be crossed by a person.

  In 4th invention, the said partition body partitions the said fire extinguishing zone and another area | region by standing up to predetermined height from a floor surface, or partitions the said fire extinguishing zone into plurality.

  According to the fourth invention, when the amount of extinguishing gas stored in the extinguishing section increases, the extinguishing gas layer formed below the air layer becomes higher. After a while, it gets over the partition and overflows from the fire extinguishing section. In this case, since the fire extinguishing gas layer is held at a predetermined height, the entire fire extinguishing section is not filled with the fire extinguishing gas. That is, an air layer can be reliably ensured above the fire extinguishing gas layer. As a result, even when a fire extinguishing gas is extinguished, it is possible to prevent a person from inhaling the fire extinguishing gas.

  The partition is preferably as high as the waist wall. In this case, as much fire extinguishing gas can be stored in the fire extinguishing section as much as possible while ensuring a state in which a person can easily breathe in the air layer. Moreover, a person can visually recognize the status of the evacuation destination from above the partition when using the fire extinguishing section as an evacuation route.

  In a fifth aspect of the present invention, a partition body drive unit that drives the partition body to perform a partitioning operation is provided, and the control unit moves the partition body when the fire-extinguishing gas is discharged from the gas discharge unit. Transition to the appearance state.

  According to the fifth aspect of the present invention, since the partition appears with the discharge of the fire extinguishing gas even if the person does not perform the operation of causing the partition to appear, the fire extinguishing gas is quickly stored in the fire extinguishing section when a fire occurs. can do. Therefore, fire extinguishing with a fire extinguishing gas can be suitably performed. In addition, if it is the structure which does not transfer a partition to an appearance state when a fire has not generate | occur | produced, the person can pass easily the appearance position of a partition. That is, the convenience of the fire extinguishing section can be enhanced during normal times.

  According to a sixth aspect of the invention, there is provided fire extinguishing detection means for detecting completion of fire extinguishing in the fire extinguishing section, air quality detecting means for detecting air quality in the fire extinguishing section, and a ventilation device for ventilating the fire extinguishing section. When the fire extinguishing detection is detected by the fire extinguishing detection means, the control means operates the ventilator based on the detection result of the air quality detecting means.

  According to the sixth aspect, when the fire extinguishing is completed, the fire extinguishing gas can be discharged from the fire extinguishing section by the ventilation device. In this case, it is possible to prevent a person who enters the fire extinguishing section from extinguishing the fire gas after the fire is extinguished. In addition, since ventilation by the ventilator is performed after the fire is extinguished, even if air is taken into the fire extinguishing section from the outside as the fire extinguishing gas is discharged, the embers are prevented from burning again by the air. it can. As a result of the above, it is possible to ensure human safety while preventing fire from reigniting after extinguishing the fire.

  In the seventh invention, a distribution board that distributes commercial power to building equipment, and auxiliary power supply that supplies power of another system to the fire fighting equipment when supply of commercial power from the distribution board to the fire fighting equipment is stopped Device.

  According to the seventh aspect, even if the supply of commercial power to the fire extinguishing equipment is stopped, the fire extinguishing equipment can be operated by the auxiliary power supplied from the auxiliary power supply device. In the event of a fire, there is a high possibility that the supply of commercial power to the fire extinguishing equipment will be stopped due to the cause of the fire being an electric leakage or the electric wire burning in the event of a fire. Since auxiliary power is supplied to the facility, it is possible to discharge the fire extinguishing gas and extinguish it.

  According to an eighth aspect of the invention, there is provided a building design apparatus for designing a building according to any one of the first to seventh aspects of the present invention, wherein whether or not a predetermined area of the building is designed to be fireproof. It is characterized by comprising determination means for determining, and display means for displaying when the design determining means determines that the fireproof specification is not satisfied.

  According to the eighth aspect of the present invention, when a building is designed, it is possible to avoid the disadvantage that the area that should originally have the fireproof specification is not the fireproof specification. Therefore, a fire prevention function can be reliably given to the building to be constructed.

  Hereinafter, an embodiment embodying the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating an example of a floor plan of a two-story building 10, and FIG. 2 is a diagram illustrating a schematic cross section of the building 10.

The second floor portion 12 is provided with a second floor corridor 31, bedrooms 32 and 33, child rooms 34 and 35, and a toilet 36 as main indoor spaces.

  As shown in FIG. 2, the building 10 is provided with a staircase space 37 as an indoor space, and the staircase space 37 is provided with a staircase 38. The staircase space 37 is a vertical hole formed by opening a boundary portion (interfloor portion) between the first floor portion 11 and the second floor portion 12. The staircase space 37 can also be referred to as an atrium space that has been blown upward from the first floor portion 11.

  In the present embodiment, a plurality of indoor spaces surrounded by walls or the like in the building 10 are individually defined as fire extinguishing sections S, and fire extinguishing equipment is provided for each fire extinguishing section S. And when a fire occurs, fire extinguishing is performed for each fire extinguishing section S. As the fire extinguishing section S, for example, in the first floor portion 11, the entrance 21 and the first floor corridor 22 are the first fire extinguishing section S1, the living room 24, the dining room 25, and the kitchen 26 are the second fire extinguishing section S2. The second floor corridor 31 is the third fire extinguishing section S3, and the child room 34 is the fourth fire extinguishing section S4. Furthermore, the staircase space 37 is the fifth fire extinguishing section S5.

  In addition to the above, the Japanese-style room 23 on the first-floor portion 11, the bedrooms 32 and 33 on the second-floor portion 12, and the child room 35 can be defined as fire-extinguishing sections, and all living rooms in the building 10 can be set as fire-extinguishing sections. . Moreover, it is also possible to define the toilet 28, the bathroom 29, etc. which are indoor space parts other than a living room as a fire extinguishing zone.

  The fire extinguishing sections S1 to S5 are each divided by an outer wall 41 and an inner wall 42 as wall bodies, and each person goes to and from the fire extinguishing sections S1 to S5 through doorways and section boundaries provided in the inner wall 42. Is possible. For example, in the first floor portion 11, the first fire extinguishing section S <b> 1 (first floor corridor 22) and the second fire extinguishing section S <b> 2 (such as the living room 24) can be moved through the entrance / exit 24 a of the living room 24. Further, in the second floor portion 12, the third fire extinguishing section S3 (second floor corridor 31) and the fourth fire extinguishing section S4 (child room 34) can be moved through the entrance 34a of the child room 34, and the third fire extinguishing section 3 is extinguished. The section S3 and the fifth fire extinguishing section S5 (the staircase space 37) can be moved back and forth via the boundary portion 37a of the staircase space 37.

  As shown in FIG. 2, the building 10 is provided with a fire extinguishing device 45 that supplies fire extinguishing gas to the fire extinguishing sections S1 to S5. The fire extinguisher 45 is configured to store or generate carbon dioxide (carbon dioxide) heavier than air as a fire extinguishing gas, and is attached to the outer wall of the building 10 outdoors, for example. The fire extinguishing device 45 is connected to a discharge head 46 as a gas discharge portion for discharging a fire extinguishing gas via a fire extinguishing pipe 47, and these discharge heads 46 are installed in each of the fire extinguishing sections S1 to S5. .

  Incidentally, the fire extinguishing device 45 is provided with a drive unit such as a pump that is driven to send out the fire extinguishing gas to the fire extinguishing pipe 47 and a valve device, and the valve device has a container valve and a selection valve. is doing. The container valve is provided for the fire extinguishing gas container, and has a function of sending out the fire extinguishing gas to the fire extinguishing pipe 47 by being opened. The selection valve is provided corresponding to each discharge head 46, and the fire extinguishing gas is discharged from the discharge head 46 corresponding to the opened selection valve. In addition, the drive part may be the structure which can adjust the pressure which sends out fire extinguishing gas. In this case, by adjusting the pressure, the fire extinguishing gas can be injected from the discharge head 46 at a high pressure or discharged at a low pressure.

  Fire extinguishing equipment is provided in each of the fire extinguishing sections S1 to S5, and the fire extinguishing equipment will be described. Here, for example, the fourth fire extinguishing section S4 (child room 34) among the fire extinguishing sections S1 to S5 will be described with reference to FIG. 3, but the other sections have the same configuration. FIG. 3 is a perspective view showing a configuration of the child room 34 as the fourth fire extinguishing section S4.

  As shown in FIG. 3, in the child room 34, in addition to the discharge head 46, there is a fire sensor 61 as a fire detection means for detecting the occurrence of a fire by sensing heat, flame and smoke, and a person. A human sensor 62 as a human detection means for detecting, an air quality sensor 63 as an air quality detection means for detecting components in the air, an operation unit 64 operated by a person, and an air quality monitor 65 for reporting information on air quality. A ventilation device 66 for performing ventilation is provided as a fire extinguishing facility.

  In this case, the fire sensor 61 and the human sensor 62 are attached to the ceiling, and the air quality sensor 63, the operation unit 64, the air quality monitor 65, the ventilation device 66, and the discharge head 46 are attached to the inner wall 42. In particular, the ventilation device 66 and the discharge head 46 are disposed in the vicinity of the floor surface of the inner wall 42, and the height of the position from the floor surface is, for example, 30 cm. Therefore, when the fire extinguishing gas is released from the discharge head 46, the fire extinguishing gas spreads from the space near the floor surface in the child room 34. On the other hand, when ventilation is performed by the ventilation device 66, the air in the vicinity of the floor surface is preferentially discharged to the outdoors in the bedroom 33. The air quality monitor 65 includes a speaker that outputs an alarm sound, an alarm monitor that displays an alarm screen, and a gas-filled lamp that indicates that fire-extinguishing gas is released into the space.

  The discharge head 46 is disposed near the floor surface and around the wall outlet. Since the outlet may become a fire source of fire due to leakage, etc., if the discharge head 46 is arranged around the outlet, the fire extinguishing gas can be discharged directly to the fire source, It is suitable for performing initial fire extinguishing. Further, the discharge head 46 may be provided integrally with the skirting board or may be provided integrally with a wall outlet.

  In addition, the discharge head 46 is disposed on the inner wall 42 on the first floor corridor 22 side in the first fire extinguishing section S1 (first floor corridor 22, entrance 21). Further, in the second fire extinguishing section S <b> 2 (the living room 24, the dining room 25, the kitchen 26), the discharge head 46 is also arranged around the gas stove, electric stove, etc. in the kitchen 26. Since gas stoves, electric stoves, etc. may become a source of fire when cooking, if the discharge head 46 is arranged around these gas stoves, electric stoves, etc., when performing initial fire extinguishment like an outlet Is preferred.

  In the building 10, movable partition devices 51 and 52 are provided on the first floor portion 11 and the second floor portion 12, respectively. The first partition device 51 of the first floor portion 11 is provided on the floor of the first fire extinguishing section S1 (first floor corridor 22) and is normally housed in the corridor floor, but a fire occurs. Sometimes, the wall forming body 51a rises from the corridor floor, and the first fire extinguishing section S1 is divided into two in this state. The second partition device 52 of the second floor portion 12 is provided at a boundary portion 37a between the third fire extinguishing section S3 (second floor corridor 31) and the fifth fire extinguishing section S5 (step space 37). However, in the event of a fire, the wall forming body 52a protrudes from the corridor wall, and the third fire extinguishing section S3 and the fifth fire extinguishing section S5 are partitioned in this state.

  The structure of the partition devices 51 and 52 will be described with reference to FIGS. FIG. 4 is an explanatory diagram for explaining the first partition device 51, and FIG. 5 is an explanatory diagram for explaining the second partition device 52. 4A shows a schematic configuration of the first partition device 51, and FIG. 4B shows a periphery of the boundary between the entrance 21 and the first floor corridor 22 in a perspective view. 5A shows a schematic configuration of the second partition device 52, and FIG. 5B shows a peripheral view of the boundary between the second-floor hallway 31 and the staircase space 37 in a perspective view.

  First, the first partition device 51 will be described. As shown to Fig.4 (a), the 1st partition apparatus 51 has the storage box 51b which accommodates the wall formation body 51a. The storage box 51b is a box formed in a substantially rectangular parallelepiped, and the length in the longitudinal direction is equal to or slightly smaller than the width of the first floor corridor 22. On the floor of the first floor corridor 22, a recess 22 a is formed in the vicinity of the boundary with the entrance 21, and the storage box 51 is installed in the recess 22 a so as to extend in the width direction of the first floor corridor 22. The storage box 51b is opened upward, and its open part is closed by a lid 51c. The lid 51c is pivotally supported with respect to the storage box 51b so as to open the storage box 51b upward. The storage box 51b is installed such that the upper surface of the lid 51c is flush with the floor surface of the first floor corridor 22. In addition, the entrance 21 is formed by the soil, and the surface of the soil is, for example, about 20 cm lower than the floor surface of the first floor corridor 22.

  The wall forming body 51a is a cloth bag body having fire resistance, and is capable of expanding and contracting. The wall forming body 51a is folded by contraction, and is stored in the storage box 51b in the folded state.

  In the first partition device 51, the wall forming body 51 a is connected to the fire extinguishing device 45 via the gas pipe 53, and the fire extinguishing gas is supplied from the fire extinguishing device 45 to the wall forming body 51 a through the gas piping 53. ing. That is, the wall forming body 51 a is expanded by supplying the gas from the fire extinguishing device 45. The gas pipe 53 is provided with an electrically driven on-off valve 56, and the gas supply to the wall forming body 51a is performed by opening the on-off valve 56. Further, the on-off valve 56 is provided with a backflow prevention mechanism for preventing a backflow of gas from the wall forming body 51a and a gas discharge mechanism for discharging the filling gas in the wall forming body 51a to the outside. When the gas is supplied to the wall forming body 51a, the wall forming body 51a is held in an upright state (a state shown by a two-dot chain line) by the backflow prevention mechanism. On the other hand, the wall forming body 51a is contracted by the gas discharge mechanism and stored in the storage box 51b. Incidentally, the lid 51c is configured to be opened along with the expansion of the wall forming body 51a.

  As shown in FIG.4 (b), when the wall formation body 51a becomes a standing state with respect to the floor surface of the 1st floor corridor 22 in the 1st partition apparatus 51, the wall formation body 51a is 1st fire extinguishing division S1. It becomes a partition which partitions off into the first floor corridor 22 side and the entrance 21. In this case, the wall forming body 51a stands up from the floor surface of the first floor corridor 22 to the same height as the shoebox, or slightly higher than the mounting position of the upper surface of the table or the lighting wall switch, etc. It has a height of 1.3m. The wall forming body 51 a has a lateral length that is equal to or slightly smaller than the width of the first floor corridor 22, and both side ends thereof are in contact with or close to the inner wall 42. The wall forming body 51a has flexibility, and a person can easily deform the wall forming body 51a. Therefore, a person can go back and forth between the first floor corridor 22 and the entrance 21 by pushing down or straddling the wall forming body 51a in the standing state. Moreover, the wall forming body 51a can return to the original standing state after a person passes. Further, since the wall forming body 51a is about the height of the waist wall, it is possible for a person to straddle the wall forming body 51a as it is without being deformed.

  For example, when the fire extinguishing gas is discharged from the discharge head 46 to the first floor corridor 22, the fire extinguishing gas flows out from the first floor corridor 22 to the entrance 21 if the wall forming body 51a of the first partition device 51 does not appear. End up. Moreover, since the level of the dirt surface of the entrance 21 is lower than the floor of the first floor corridor 22, the fire extinguishing gas accumulates in the entrance 21 before the first floor corridor 22 and is not easily stored in the first floor corridor 22. . Further, if the entrance door is opened, the fire extinguishing gas does not collect in the entrance 21 and goes out outdoors. On the other hand, when the wall forming body 51a appears, the outflow of the fire extinguishing gas to the entrance 21 is restricted, so that the fire extinguishing gas is stored in the first floor corridor 22. In this case, even if a fire occurs using the wall outlet of the first floor corridor 22 as a fire source, the initial fire extinguishing is performed by the fire extinguishing gas stored around the fire source.

  If the fire extinguishing gas is continuously released, the fire extinguishing gas eventually passes over the wall forming body 51a and flows out to the entrance 21. In this case, since the fire extinguishing gas layer does not become higher than the upper end of the wall forming body 51a, even if there is a person in the first floor corridor 22, only the lower half of the person enters the fire extinguishing gas layer, so that the person Inhalation can be suppressed. Moreover, a person can escape from the first floor corridor 22 through the entrance 21 across the wall forming body 51a.

  Next, the second partition device 52 will be described. As shown to Fig.5 (a), the 2nd partition device 52 has the storage box 52b which accommodates the wall formation body 52a. The storage box 52b is a box formed in a substantially rectangular parallelepiped, and the length in the longitudinal direction is equal to or slightly smaller than the waist wall 58 between the second floor corridor 31 and the staircase space 37. The inner wall 42 of the second floor corridor 31 is formed with a recess 31a in the vicinity of the boundary 37a with the staircase space 37, and the storage box 52b is installed in the recess 31a so as to extend in the vertical direction. The storage box 52b is opened on the opposite side of the waist wall 58 across the boundary 37a, and the open part is closed by a lid 52c. The lid 52c is pivotally supported with respect to the storage box 52b, and opens the storage box 52b to the side by rotating. The storage box 52b is installed such that one side surface of the lid body 52c forms the same plane as the wall surface of the second floor hallway 31.

  Similar to the wall forming body 51a of the first partition device 51, the wall forming body 52a of the second partition device 52 is a cloth-made bag body having fire resistance, and can be expanded and contracted. . The wall forming body 52a is folded by contraction, and is stored in the storage box 52b in the folded state.

  Similarly to the first partition device 51, in the second partition device 52, the wall forming body 52 a is connected to the fire extinguishing device 45 through the gas pipe 53, and the gas pipe 53 has an electrically driven on-off valve 56. Is provided. Incidentally, the lid body 52c is configured to be opened along with the expansion of the wall forming body 52a.

  As shown in FIG.5 (b), when the wall formation body 52a will be in the standing state with respect to the floor surface of the second-floor hallway 31 in the 2nd partition device 52, the wall formation body 52a will be 3rd fire extinguishing division S3 ( The second floor corridor 31) and the fifth fire extinguishing section S <b> 5 (the staircase space 37) are separated from each other by the boundary 37 a of the staircase space 37. In this case, the wall forming body 52a stands up from the floor surface of the second-floor corridor 31 to the height of the waist wall 58, and has a height of, for example, 1.3 m. The wall forming body 52a has a lateral length that is equal to or slightly smaller than the width of the second-floor corridor 31, and both side ends thereof are in contact with or close to the inner wall 42 and the waist wall 58. Similarly to the wall forming body 51a of the first partition device 51, a person can go back and forth between the second floor corridor 31 and the staircase space 37 by pushing down or straddling the wall forming body 52a in the standing state. .

  For example, when the fire extinguishing gas is released to the second floor corridor 31, the fire extinguishing gas flows out from the second floor corridor 31 to the staircase space 37 if the wall forming body 52a of the second partition device 52 does not appear. Moreover, since the level of the staircase surface of the staircase 38 is lower than the floor surface of the second floor hallway 31, the fire extinguishing gas flows down to the first floor portion 11 and is not stored in the second floor hallway 31. On the other hand, when the wall forming body 52a appears, the outflow of the fire extinguishing gas to the staircase space 37 is restricted, so that the fire extinguishing gas is stored in the second floor corridor 31. In this case, even if a fire occurs in the second-floor corridor 31, initial fire extinguishing is performed by the fire extinguishing gas stored around the fire source.

  If the fire extinguishing gas is continuously released, the fire extinguishing gas eventually passes over the wall forming body 52a and flows out to the staircase space 37. In this case, in the same way as the wall forming body 51a in the first floor corridor 22, it is possible to prevent a person from inhaling the fire extinguishing gas, and the person evacuates from the second floor corridor 31 through the stairs 38 to the first floor portion 11 or outdoors. can do.

  Next, the electrical configuration of the fire extinguishing system will be described. Here, the structure regarding the control system of a fire extinguishing system and the structure regarding a power supply system are demonstrated. First, the structure regarding the control system of a fire extinguishing system is demonstrated using FIG.

  As shown in FIG. 6, the fire extinguishing system includes a home server 71. The home server 71 has a microcomputer including a CPU and various memories, and is installed in the living room 24, for example. Here, the home server 71 serves as a fire extinguishing equipment control panel.

  A fire sensor 61, a human sensor 62, an air quality sensor 63, and an operation unit 64 are connected to the home server 71. The fire sensor 61 detects the human sensor 62, the air quality sensor 63, and the operation unit 64. A signal is output to the home server 71. Here, the operation part 64 permits discharge of the fire-extinguishing gas into the fire-extinguishing sections S1 to S5 by manual operation, and a permission signal by the manual operation is output to the home server each time.

  The air quality sensor 63 is configured to detect information related to carbon dioxide, carbon monoxide, humidity, temperature, pollen, dust, other dirt in the air, and the like. include. The home server 71 monitors (monitors) all the air qualities of the fire extinguishing sections S1 to S5 based on the detection signal of the air quality sensor 63, and sets any one of the fire extinguishing sections S1 to S5. The monitoring result is output as a signal to the arranged air quality monitor 65. In this case, the air quality monitor 65 serves as a centralized monitor that displays the overall air quality status of the building 10.

  The home server 71 is connected to a fire extinguishing device 45, partitioning devices 51 and 52, an air quality monitor 65, a ventilation device 66, and a fire alarm device 72. The home server 71 outputs these by outputting a command signal. Operation control of the fire extinguishing device 45, the partition devices 51 and 52, the air quality monitor 65, the ventilation device 66, and the fire alarm device 72 is performed. Here, the fire alarm device 72 is configured to emit an alarm sound or display an alarm screen, and is installed in a common part of the building 10 such as the first-floor corridor 22 or the second-floor corridor 31, for example. Thereby, it becomes possible to make all the people in the building 10 recognize that the alarm is issued by the fire alarm device 72. The fire alarm device 72 has an activation device, and the home server 71 sends an alarm to the fire alarm device 72 by transferring a signal to the activation device (outputting a transmission signal to notify the occurrence of a fire). It is configured to do.

  Next, an electrical configuration related to the power supply system of the fire extinguishing system will be described with reference to FIG.

  As shown in FIG. 7, the building 10 is provided with a service port 74 to which a distribution line is connected from the outside, and a distribution board 75. The distribution board 75 has a main breaker 77 connected to the service port 74 via a watt-hour meter (WHM) 76 and a branch breaker 78 connected to the downstream side of the main breaker 77. A plurality of branch breakers 78 are provided on the distribution board 75, and an uninterruptible power supply (UPS) 79 as an auxiliary power supply device is connected to the downstream side of at least one branch breaker 78 among them. In this case, commercial power from an external power source is supplied to the uninterruptible power supply 79 via the service port 74, the watt hour meter 76, and the distribution board 75.

  On the downstream side of the uninterruptible power supply 79, the home server 71, fire sensor 61, human sensor 62, air quality sensor 63, operation unit 64, fire extinguishing device 45, air quality monitor 65, ventilation device 66, fire alarm device 72 Are connected as system equipment A constituting the fire extinguishing system. The uninterruptible power supply 79 has a power storage unit such as a secondary battery, and stores power in the power storage unit while supplying power downstream when commercial power is supplied. On the other hand, even when commercial power is not supplied, power is supplied from the power storage unit to the downstream side. Therefore, in the present embodiment, power is supplied to the system facility A not only when power is supplied to the uninterruptible power supply 79 but also when power supply to the uninterruptible power supply 79 is stopped. Supplied. In this case, the circuit of the uninterruptible power supply 79 is a dedicated circuit for the fire extinguishing system. The uninterruptible power supply 79 has a configuration capable of storing, in the power storage unit, power that can supply power to the system facility A for a predetermined time such as about 10 minutes.

  For example, if an electrical leakage occurs at the outlet or an overcurrent flows, causing a fire, and the main breaker 77 is shut off due to the occurrence of the electrical leakage, the power to the uninterruptible power supply 79 is Supply is stopped. However, even in this case, since the uninterruptible power supply 79 supplies power from the power storage unit to the system facility A, it is possible to extinguish the fire with the fire extinguishing system. In addition, even if an electrical wiring or a distribution board burns due to a fire, the fire extinguishing system can be used to extinguish the fire.

  Here, the fire extinguishing process executed by the home server 71 will be described with reference to the flowchart of FIG. The fire extinguishing process is executed at a predetermined time period.

  In FIG. 8, in step S <b> 101, various detection signals output from the fire sensor 61, the human sensor 62, the air quality sensor 63, and the operation unit 64 are acquired. In step S102, it is determined whether or not a fire has occurred in the building 10 based on the detection signals of the fire sensors 61 in the fire extinguishing sections S1 to S5. If a fire has occurred, the process proceeds to step S103, and a section where the fire has occurred among the fire extinguishing sections S1 to S5 is specified as a fire generating section. In this case, the fire alarm device 72 is caused to perform a fire alarm operation in order to notify a resident or the like that a fire has occurred in the fire occurrence section, and an alarm sound is output or an alarm screen is displayed.

  In step S104, based on the detection signal of the human sensor 62, it is determined whether or not there is a person in the fire occurrence section among the fire extinguishing sections S1 to S5. The operation of the device 45 is controlled, and the fire extinguishing gas is discharged from the discharge head 46 in the fire occurrence section.

  In step S106, the air quality monitor 65 is made to perform a gas alarm operation to notify the resident and the like that the fire extinguishing gas is released in the fire occurrence section, and an alarm sound is output or an alarm screen is displayed. Further, when the fire extinguishing gas is released from the discharge head 46, the pressure switch of the fire extinguishing device 45 is activated and the gas filling lamp of the air quality monitor 65 is turned on. Further, here, based on the detection result of the air quality sensor 63, it is determined whether or not the fire extinguishing gas is present in the fire extinguishing sections S1 to S5, and when the fire extinguishing gas is present, the fire extinguishing sections S1 to S5 are determined. The air quality monitor 65 is made to perform a gas alarm operation assuming that the air quality is not normal. Therefore, when the discharge of the fire extinguishing gas is stopped, or even in the fire extinguishing sections S1 to S5 where the fire extinguishing gas is not released from the discharge head 46, if the air quality of the fire extinguishing sections S1 to S5 is not normal, the gas from the air quality monitor 65 Alarm action continues.

  For example, when a fire has occurred in the child room 34, the fire occurrence section is specified as the fourth fire fighting section S4, and the fire extinguishing gas is discharged from the discharge head 46 of the fourth fire fighting section S4. In this case, the fire extinguishing gas is stored in the child room 34 when the doorway 34a is closed by a door. Here, since the fire extinguishing gas is heavier than air, a fire extinguishing gas layer mainly composed of the fire extinguishing gas is formed below the air layer. Therefore, even if a fire occurs near the floor due to forgetting to extinguish the cigarette fire or ignite dust, fire extinguishing gas is quickly released to the fire source and around the fire source. Since the fire extinguishing gas is retained, initial fire extinguishing can be suitably performed. Further, in this case, the initial fire extinguishing can be performed without detecting the occurrence of a fire by a person. Furthermore, since there is no person in the child room 34 where the fire is occurring, the person does not inhale the fire extinguishing gas. In addition, since a gas release alarm is issued in the child room 34, it is possible to alert a person to entering the child room 34 while the gas is being released. Therefore, human safety can be ensured during fire extinguishing.

  If there is a person in the fire occurrence zone (if YES in step S104), the process proceeds to step S114, and based on the detection signal from the operation unit 64, the operation unit 64 determines whether a manual permission operation has been performed. . If the permission operation is not performed, the fire extinguishing process is terminated as it is, and the fire extinguishing gas is not released. Thereby, it can avoid that the person in a fire outbreak section breathes in fire extinguishing gas.

  On the other hand, if the permission operation is performed, the fire extinguishing gas is released to the fire occurrence section in step S105, and the air quality monitor 65 is caused to perform a gas alarm operation in step S106. In this case, even if there is a person in the fire occurrence section, when the person performs the permission operation of the operation unit 64, the fire extinguishing gas is released to the fire occurrence section, and the initial fire extinguishing can be performed. Moreover, in the fire occurrence section, the amount of extinguishing gas stored is small for a while after the start of the extinguishing of the extinguishing gas, and an air layer is reliably secured. In addition, the discharge head 46 discharges the fire extinguishing gas with such a force that no air flow occurs in the fire generating section so as not to stir the fire extinguishing gas layer and the air layer. Therefore, the person can breathe safely in the air layer without inhaling the fire extinguishing gas. As a result, even when a person is in a fire occurrence zone, it is possible to perform the initial fire extinguishing while ensuring the safety of the person.

  After releasing the fire extinguishing gas, in step S107, it is determined whether or not the partition devices 51 and 52 are to be operated. Here, it is determined that the first partition device 51 is operated when the fire occurrence zone is in the first floor portion 11 (fire extinguishing zone S1, S2, S5), and the fire occurrence zone is the second floor portion 12 (fire extinguishing zone S3 to S5). If it is, the second partition device 52 is determined to be operated.

  When operating the partition devices 51 and 52, it progresses to step S108, the partition devices 51 and 52 are operated, and the wall formation bodies 51a and 52a appear. For example, when the fire occurrence section is in the first floor portion 11, the wall forming body 51 a of the first partition device 51 appears to partition the first fire-extinguishing section S <b> 1 into the first floor hallway 22 and the entrance 21. In this case, since the fire extinguishing gas is stored in the first floor corridor 22, the first floor corridor 22 is extinguished and the first floor corridor 22 is secured as an evacuation route. In addition, when the fire occurrence section is in the second floor portion 12, the wall forming body 52a of the second partition device 52 appears, and the second floor hallway 31 as the third fire extinguishing section S3 and the staircase space 37 as the fifth fire extinguishing section S5. Partition. In this case, since the fire extinguishing gas is stored in the staircase space 37, the second floor corridor 31 is extinguished and the second floor corridor 31 is secured as an evacuation route.

  In step S109, based on the detection signal of the fire sensor 61, it is determined whether or not the fire extinguishing is completed. That is, it is determined whether or not the fire has been extinguished. If the fire is not extinguished, the fire extinguishing process is terminated as it is, and fire extinguishing with a fire extinguishing gas is continued. On the other hand, when the fire has been extinguished, the process proceeds to step S110, and the supply of the extinguishing gas from the extinguishing device 45 to the discharge head 46 is stopped, thereby stopping the discharge of the extinguishing gas from the discharge head 46. In step S111, the supply of fire extinguishing gas from the fire extinguishing device 45 to the partition devices 51 and 52 is stopped, and the wall forming bodies 51a and 52a are squeezed by discharging the fire extinguishing gas from the wall forming bodies 51a and 52a by the gas discharge mechanism. And store it. Thereby, storage of the fire extinguishing gas in the fire extinguishing sections S1 to S5 is released, and the fire extinguishing gas flows out to other areas.

  In step S112, based on the detection signal of the air quality sensor 63, it is determined whether or not the air quality of the fire extinguishing sections S1 to S5 is normal. If the air quality is not normal, it is determined that fire extinguishing gas remains in the fire extinguishing sections S1 to S5, the process proceeds to step S113, the operation of the ventilator 66 is controlled, and the fire extinguishing gas is forcibly discharged from the fire extinguishing sections S1 to S5 to the outside. . In this case, since the ventilator 66 is disposed near the floor surface, when the ventilator 66 is operated, the air near the floor surface is preferentially discharged to the outdoors. That is, the fire-extinguishing gas is discharged to the outdoors before the air in the fire-extinguishing sections S1 to S5, and the ventilation efficiency can be increased. Moreover, since the gas alarm operation | movement in step S106 is performed continuously, it can avoid that a person enters fire extinguishing section S1-S5 where fire extinguishing gas remains. In other words, it is possible to avoid the occurrence of a secondary disaster in which a person inhales residual fire extinguishing gas after extinguishing.

  If the air quality is normal, it is determined that no fire extinguishing gas remains in the fire extinguishing sections S1 to S5, the process proceeds to step S115, and the operation of the ventilator 66 is stopped. In this case, the operation of the air quality monitor 65 is controlled to stop the gas alarm operation. Thereby, the person can recognize that the fire extinguishing gas does not remain in the fire extinguishing sections S1 to S5, and can enter the fire extinguishing sections S1 to S5.

  By the way, the building 10 is constructed based on the design drawing supported by the design apparatus. The design device is composed of a personal computer that operates a dedicated program such as CAD, and the input device such as a keyboard is operated by the designer to acquire input data, and the drawing is displayed on the display or the like according to the input data. Display on the display device. In addition, the design apparatus outputs the drawing as CAD data to the outside, or outputs it on a paper surface by a printing apparatus such as a printer.

  The design apparatus has a function of automatically setting a fire spreading line (fire prevention line) and a fire extinguishing section S that indicate a portion that may spread when a fire occurs in an adjacent building when designing the building 10. Here, design support performed by the design apparatus will be described with reference to FIGS. FIG. 9 is a diagram showing a display screen 81, and FIG. 10 is a diagram showing a first floor floor plan 95 and a second floor floor plan 96. In FIG. 10, (a) shows a first floor floor plan 95, and (b) shows a second floor floor plan 96.

  First, the automatic setting function of the fire spread line will be described.

  As shown in FIG. 9, a horizontal projection view 82 of a site, a building, or the like is displayed on the display screen 81 of the design apparatus. Specifically, the horizontal projection 82 displays the adjacent land boundary line 83, the road center line 84, the size and shape of the building 10, and the fire spreading line (the first floor fire spreading line of the first floor portion 11 of the building 10). ) 85 and a fire spreading line 86 of the second floor portion 12 (second fire spreading line) 86 are displayed. Each of the fire spread lines 85 and 86 is defined as an area (fire spread area) where the outer area may be spread from an adjacent building. In the illustrated example, the second floor fire spread line 86 is on the first floor. It is defined inside the fire spread line 85. In addition, the display screen 81 displays an input menu 91 that allows data related to the adjacent land line 83, the road width, the size of the building 10, and the like to be input.

  When designing a building, one of the input menus 91 is selected by the designer in the design apparatus, and predetermined design data is input. Then, the design apparatus displays the adjacent land boundary line 83, the road center line 84, the size and shape of the building 10 and the like on the display screen 81 as the horizontal projection view 82 based on the inputted design data. Further, the positions of the first floor fire spread line 85 and the second floor fire spread line 86 are calculated based on the input design data, and the fire spread lines 85 and 86 are added to the horizontal projection view 82 and displayed on the display screen 81.

  Also, as shown in FIG. 10, floor plans 95 and 96 in the first floor part and the second floor part of the building are displayed on the display screen 81 based on the floor plan data and the like. In this case, the design apparatus also draws the fire spread lines 85 and 86 calculated as described above in the floor plans 95 and 96 and displays them on the display screen 81. In FIG. 10 (a), A1 and A2 are shaded and displayed as a fire spread area in the first floor floor plan 95, and in FIG. 10 (b), B1 is a fire spread area in the second floor floor plan 96. Are indicated by shading, coloring or the like.

  In addition, in the state where the floor plans 95 and 96 are displayed on the display screen 81, predetermined design data is input, and the fire spread lines 85 and 86 calculated based on the input data are displayed in the floor plans 95 and 96. May be. Even in this case, if the horizontal projection 82 is displayed on the display screen 81, the fire spread lines 85 and 86 are displayed on the horizontal projection 82.

  In addition to the guidance display of the fire spread areas A1, A2, and B1, the design apparatus checks whether or not various members have a predetermined fireproof / fireproof structure and performance in the fire spread areas A1, A2, and B2. That is, whether or not roofs and outer walls in the fire spread areas A1, A2, and B1 satisfy predetermined fire resistance and fire prevention standards, and building facilities such as ventilation fans and dampers in the fire spread areas A1, A2, and B1 have predetermined fire resistance and fire prevention. Whether or not the standard is satisfied is checked by selecting a position mode such as an external joinery in the input menu 91. In this case, when the various members in the fire spread areas A1, A2, B1 do not satisfy the predetermined fire resistance / fire prevention standards, the design device displays the corresponding members in color or provides voice guidance to the designer. Implement the warning.

  Further, in the design apparatus, when the member selects the member change mode in the input menu 91 and the member to be changed is selected in the horizontal projection view 82 or the floor plans 95 and 96, the selected member is selected. Will be changed to a member that meets fire and fire protection standards. For this reason, with respect to various members, the operation for checking the fire resistance / fire prevention standards and the operation for changing the members can be continuously performed by one input menu 91.

  Next, the automatic setting function of the fire extinguishing section S will be described.

  In this function, similarly to the function of automatically setting the fire spread line 85, when the floor plans 95 and 96 in the first floor part and the second floor part are displayed on the display screen 81, the fire extinguishing section S is located in the living room 24 or the dining room 25. Each fire extinguishing section S is guided and displayed by shading, coloring or the like. In the fire extinguishing section S, a discharge head 46, a fire sensor 61, a human sensor 62, an air quality sensor 63, an operation unit 64, an air quality monitor, a ventilation device 66, and the like are arranged as fire extinguishing equipment. Is displayed by guidance with symbols indicating the facilities. Further, the design apparatus checks whether the fire extinguishing section S and the fire extinguishing equipment satisfy a predetermined standard. Here, the predetermined standard is a standard arbitrarily set by a designer or the like, and if the standard is not satisfied, the design apparatus colors and displays the corresponding fire extinguishing section S and fire extinguishing equipment or provides voice guidance. To alert the designer.

  Further, in the automatic setting of the fire extinguishing section S, the setting mode (not shown) of the fire extinguishing section S and the fire extinguishing equipment is provided in the input menu 91 as in the automatic setting of the fire spreading line 85, and the setting mode is set by the designer. When the fire extinguishing section S, the building space, and the fire extinguishing equipment to be changed are selected in the floor plans 95 and 96, the layout change, installation, and deletion of the fire extinguishing section S and the fire extinguishing equipment may be performed. It is possible. For this reason, regarding the fire extinguishing section S and the fire extinguishing equipment, the operation for checking the arrangement and the operation relating to the change can be continuously performed by one input menu 91.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  Since fire occurrence is detected by the fire sensor 61 in the fire extinguishing sections S1 to S5, initial fire extinguishing can be suitably performed. Since fire extinguishing is performed by releasing the fire extinguishing gas, it is possible to extinguish the building 10 and the building equipment while the fire extinguisher is completed and can be used. That is, it is possible to avoid the occurrence of water loss due to water discharge, fouling due to powder fire extinguishing agent and foam extinguishing agent. If water damage or pollution occurs, even if the building 10 or building equipment is not burned, it is considered that a loss equivalent to that of the case of burning is caused, so it is effective to extinguish with fire extinguishing gas. is there.

  Since the indoor spaces such as the first-floor corridor 22 and the child room 34, which are surrounded by walls, are set as the fire extinguishing sections S1 to S5, when fire extinguishing gas is released into the fire extinguishing sections S1 to S5, It is regulated that the fire extinguishing gas flows out from the fire fighting sections S1 to S5. Further, the first floor corridor 22 and the entrance 21 are partitioned by the wall forming body 51a of the first partition device 51, and the second floor corridor 31 and the staircase space 37 are partitioned by the wall forming body 52a of the second partition device 52. Therefore, even if it is a space communicating with an adjacent space such as the first floor corridor 22 or the second floor corridor 31, it is possible to restrict the flow of fire-extinguishing gas from that space. In this case, it is avoided that the fire extinguishing gas is diluted in the fire extinguishing sections S1 to S5, and the fire extinguishing gas can exhibit the fire extinguishing ability continuously from the initial fire extinguishing. As a result, it is possible to prevent the fire from spreading from the fire occurrence section to another space in the building 10.

  When a fire occurs in the fire extinguishing sections S1 to S5, if there is no person in the fire generating section, the fire extinguishing gas is automatically released, but if there is a person in the fire generating section, the operation unit 64 is manually operated. Fire extinguishing gas is released only when Therefore, since the fire extinguishing gas is not unexpectedly released to the person in the fire occurrence section, the possibility that the person inhales the fire extinguishing gas can be reduced. In addition, even when the operation unit 64 is manually operated and the fire extinguishing gas is released, the fire extinguishing gas layer is formed below the air layer, so that a person breathes in the air layer even in the fire occurrence section. Can do. Moreover, since the discharge head 46 is provided in the vicinity of the floor, the fire extinguishing gas is released from the vicinity of the floor surface, and the fire extinguishing gas layer and the air layer are not easily stirred, and these layers do not mix with each other. . Therefore, a person can breathe safely without inhaling the fire extinguishing gas even in the fire occurrence section.

  As a result, in the configuration in which the fire is extinguished by the fire extinguishing gas, it is possible to improve human safety while suitably performing the initial fire extinguishing.

  By the appearance of the wall forming body 51a of the first partition device 51, it becomes possible to store the fire extinguishing gas in the first floor corridor 22 as the first fire fighting section S1. In this case, since the first floor corridor 22 is extinguished when a fire occurs, a person can use the first floor corridor 22 as an evacuation route. Accordingly, a person can evacuate safely through the first floor corridor 22 without having to escape to the outdoors through the windows formed in the living room 24, the first floor corridor 22 or the like. Further, the appearance of the wall forming body 52a of the second partition device 52 makes it possible to store the fire extinguishing gas in the second floor corridor 31 as the third fire extinguishing section S3. In this case, since the second floor corridor 31 is extinguished when a fire occurs, a person can use the second floor corridor 31 as an evacuation route. Furthermore, since the fire extinguishing gas does not flow from the second floor corridor 31 to the staircase space 37 as a vertical hole by the wall forming body 52a of the second partition device 52, the second floor portion 12 can be suitably extinguished.

  Since carbon dioxide is used as the fire extinguishing gas, even if a fire extinguishing gas layer with a high carbon dioxide concentration is formed in the lower space of the fire extinguishing sections S1 to S5 when a fire occurs, there is no adverse effect on the human body unless the person inhales. . Accordingly, it is preferable to use carbon dioxide as the fire extinguishing gas in a configuration that can prevent a person from inhaling the fire extinguishing gas during fire extinguishing.

  When design support is performed by the design apparatus, the fire spread lines 85 and 86 are automatically set, and the fire spread lines 85 and 86 are displayed on the display screen 81 in the horizontal projection view 82 and the floor plans 95 and 96. In this case, since there is no need to output the horizontal projection 82 or the like on a sheet of paper and handwriting the fire spreading lines 85 and 86 on the horizontal projection 82 or the like, design work and check work related to the fire spreading lines 85 and 86 can be efficiently performed. It can be carried out.

  The design device checks whether or not various members in the fire spread areas A1, A2, and B1 satisfy predetermined fire and fire prevention standards. For example, the designer visually checks the members on the CAD display screen 81. There is no need to check the design drawings or estimates printed on the paper for each item. Therefore, the check work regarding the fire spread areas A1, A2, and B1 can be efficiently performed. In addition, in the design apparatus, in addition to the check operation, it is possible to change to a member that satisfies the fire resistance / fire prevention standards, so the designer can perform the check operation and the member change operation continuously. . Therefore, work related to member change can be performed efficiently.

(Other embodiments)
The present invention is not limited to the description of the above embodiment, and may be implemented as follows, for example.

  (1) Instead of carbon dioxide gas, nitrogen gas may be supplied to the fire extinguishing sections S1 to S5 as a fire extinguishing gas. In short, a gas having the ability to extinguish the flame by being released to the flame may be supplied to the fire extinguishing sections S1 to S5 as a fire extinguishing gas. Thereby, initial fire extinguishing and emergency fire extinguishing can be appropriately performed by the fire extinguishing gas.

  (2) In the partition devices 51 and 52, the wall forming bodies 51a and 52a may be airbag-type wall forming bodies that appear to expand when air is injected instead of the fire extinguishing gas, and the drive unit is driven. The folding wall forming body which appears by doing may be sufficient. Moreover, it may be a door-type wall forming body that is pivotally supported so as to be openable and closable with respect to the inner wall 42, shifts to a storage state when opened, and shifts to an appearance state when closed. In this case, when the wall forming bodies 51a and 52a are in the storage state, the wall forming bodies 51a and 52a and the inner wall 42 are overlapped to form a double wall. Furthermore, the wall forming bodies 51a and 52a may be configured to be easily broken by a thin plate material, for example. In this case, the person can easily break the wall forming bodies 51a and 52a, and can get over the wall forming bodies 51a and 52a in the standing state.

  Further, the partition devices 51 and 52 may be installed integrally with the clog box of the entrance 21 instead of the floor or the inner wall 42, and are installed with the storage boxes 51b and 52b exposed in a dedicated space such as the first floor corridor 22. May be.

  (3) The wall forming bodies 51a and 52a of the partition devices 51 and 52 have a height that is about the waist wall, but may have a height that reaches the ceiling. In short, the wall forming bodies 51a and 52a may be configured to restrict the fire extinguishing gas from flowing out and partition the fire extinguishing sections S so that a person can pass or partition the fire extinguishing sections S into a plurality of sections.

  (4) The discharge head 46 may be attached to the floor of the fire extinguishing sections S1 to S5. In this case, since the fire-extinguishing gas is released from the floor surface, it is possible to avoid stirring the fire-extinguishing gas layer and the air layer in the fire-extinguishing sections S1 to S5. The discharge head 46 may be configured to discharge the fire extinguishing gas toward the floor surface or downward. In this configuration, the discharge head 46 may be disposed at a position higher than the vicinity of the floor in the inner wall 42 or the outer wall 41, or may be disposed on the ceiling. That is, the installation height of the discharge head 46 may be arbitrary. Even in this case, when the fire extinguishing gas is released from the discharge head 46, the fire extinguishing gas layer is formed under the air layer, so that it is possible to prevent a person from inhaling the fire extinguishing gas.

  (5) The ventilation unit 66 may be provided with an operation unit that performs a manual operation. In this case, since the ventilation device 66 is operated or stopped by manually operating the operation unit, after the fire is completed, the person can actually check the visual recognition and then ventilate the fire extinguishing sections S1 to S5. it can. Therefore, it is possible to suppress the embers from starting to burn again vigorously, and as a result, the fire can be reliably extinguished.

  (6) The inner wall 42 may be made of a fireproof member. In this case, the inner wall 42 regulates the fire from spreading to another fire extinguishing section S. Therefore, it is suitable as a configuration for preventing the spread of fire in the building 10.

  (7) Only the kitchen 26, the dining room 25, the first floor corridor 22 and the entrance 21 may be set as different fire extinguishing sections S. In this case, even if a fire occurs using the kitchen 26 as a fire source, the dining room 25, the first floor corridor 22 and the entrance 21 can be secured as an evacuation route, so that a person in the kitchen 26 can quickly escape from the entrance 21 to the outdoors. Can do. In addition, if the kitchen 26 is provided with a user's door, for example, when a fire occurs in the dining room 25, a person can escape from the user's door to the outside using the kitchen 26 as an evacuation route.

  (8) The 1st partition apparatus 51 may be provided in the boundary part of the fire extinguishing division S which adjoins. For example, if the first partition device 51 is provided at the entrance 24a of the living room 24, the first floor corridor 22 as the first fire extinguishing section S1 and the living room 24 as the second fire extinguishing section S2 by causing the wall forming body 51a to appear. The dining room 25 and the kitchen 26 can be partitioned. Moreover, the 2nd partition device 52 may be provided in the position which divides | segments one fire extinguishing division S into plurality.
