Description

本発明は、建物における防火設備に係わり、特に水幕による水幕型防火防煙設備及び防火防煙方法に関する。   The present invention relates to fire prevention equipment in buildings, and more particularly, to a water curtain type fire prevention smoke prevention equipment and a fire prevention smoke prevention method using a water curtain.

近年、建物内の防火設備は、火災箇所の周囲に水幕を形成させて延焼や熱による被害を防止する水幕型防火設備が使用されている。
この水幕防火設備として、例えば特許文献１に提案されているものがある。
特許文献１は、火災発生空間と避難スペースとなる安全空間との間に、二重の水幕により囲まれた緩衝区間を形成させることで、遮炎効果を向上させた設備である。この緩衝空間は、床面に集水部を設けて放出された水を集水して貯留させるものであり、床面が貯留水に覆われているため吸熱効果が発揮されて緩衝空間の温度を低減させることができる。
特開２００４−３０５３８０号公報 In recent years, a fire curtain type fire prevention equipment that forms a water curtain around a fire spot to prevent damage due to fire spread or heat has been used.
As this water curtain fire prevention equipment, there is one proposed in Patent Document 1, for example.
Patent Document 1 is a facility that improves a flame shielding effect by forming a buffer section surrounded by a double water curtain between a fire occurrence space and a safety space serving as an evacuation space. This buffer space is provided with a water collecting part on the floor surface to collect and store the discharged water, and since the floor surface is covered with the stored water, an endothermic effect is exhibited and the temperature of the buffer space is reduced. Can be reduced.
JP 2004-305380 A

しかしながら、特許文献１に示される水幕防火設備は、水幕自体に隙間が形成されるため、防煙性能が低く、火災箇所で発生した煙が水幕を通過し、安全空間に侵入して拡散されてしまうという欠点があった。また、水幕は、高温となる火災発生空間に隣接しているため、水蒸気が発生し、煙と同様に建物内部に拡散していた。
このように煙と水蒸気が建物内部の視界を遮ってしまい安全性を低下させ、避難や消火活動に支障を来たすという問題があった。
また、このような課題があるため、従来の水幕防火設備における適用範囲は、建築基準法上に基づく面積区画に限定されているのが現状となっている。建築基準法で定める面積区画の場合は、遮炎性能を有していればよく、関係法令上で防煙性能がなくても従来の水幕防火設備が適用できることが多い。しかし、例えば階段室やエレベータシャフトなど（建築基準法に定める竪穴区画）や、劇場、映画館、ホテルなど（同じく異種用途区画）、関係法令上の基準が高く防煙性能が要求される場合には、水幕防火設備だけでその基準を満足することができないという問題があった。 However, since the water curtain fire prevention equipment shown in Patent Document 1 has a gap formed in the water curtain itself, the smoke prevention performance is low, and smoke generated at the fire passes through the water curtain and enters the safety space. There was a drawback of being diffused. In addition, the water curtain is adjacent to the high temperature fire generating space, so water vapor is generated and diffused inside the building like smoke.
As described above, there is a problem that smoke and water vapor block the view of the inside of the building, thereby reducing safety and hindering evacuation and fire fighting activities.
Moreover, since there exists such a subject, it is the present condition that the application range in the conventional water curtain fire prevention equipment is limited to the area division based on a building standard law. In the case of an area section defined by the Building Standards Act, it is sufficient if it has a flame shielding performance, and the conventional water curtain fire prevention equipment is often applicable even if there is no smoke prevention performance according to related laws and regulations. However, for example, when staircases or elevator shafts (eg, pit holes defined in the Building Standards Act), theaters, movie theaters, hotels, etc. However, there was a problem that the standards could not be satisfied with water curtain fire protection equipment alone.

本発明は、上述する問題点に鑑みてなされたもので、煙や水蒸気の拡散を防止して避難や消火活動の安全性を向上させ、適用範囲を拡大させた水幕型防火防煙設備及び防火防煙方法を提供することを目的としている。   The present invention has been made in view of the above-described problems, and has improved the safety of evacuation and fire fighting activities by preventing the diffusion of smoke and water vapor, and has expanded the application range, and It aims to provide a fire and smoke prevention method.

上記目的を達成するため、本発明に係る水幕型防火防煙設備では、水幕を形成させる噴出口を有して水幕によって火災区画と非火災区画とを区画する水幕型防火設備と、非火災区画に空気を送り込んで加圧する加圧手段と、火災区画から屋外に排気する排煙手段とを備えていることを特徴としている。
本発明では、火災時に火災箇所を水幕によって取り囲み、その水幕の外側で隣接する非火災区画を加圧手段によって加圧することで、水幕の内外の区画に圧力差を生じさせることができる。このとき加圧された非火災区画の圧力が大きくなり、空気が水幕の隙間を通過して水幕の外方から内側の方向に気流が形成されるため、火災箇所で発生する煙や水蒸気は水幕より外側に拡散されない。したがって、この水幕外の非火災区画では、視界が遮られず、避難や消火活動の安全性を向上させることができる。 In order to achieve the above object, in the water curtain type fire prevention and smoke prevention equipment according to the present invention, there is provided a water curtain type fire prevention equipment having a spout for forming a water curtain and dividing the fire compartment and the non-fire compartment by the water curtain. The pressure means for sending air to the non-fire compartment and pressurizing the smoke and the smoke exhaust means for exhausting the fire compartment to the outside are provided.
In the present invention, a fire spot is surrounded by a water curtain in the event of a fire, and a non-fire section adjacent to the outside of the water curtain is pressurized by the pressurizing means, whereby a pressure difference can be generated in the inner and outer sections of the water curtain. At this time, the pressure of the pressurized non-fire compartment increases, and air passes through the gap of the water curtain and an air flow is formed from the outside to the inside of the water curtain. Does not spread outside the water curtain. Therefore, in the non-fire section outside the water curtain, the view is not obstructed, and the safety of evacuation and fire fighting activities can be improved.

また、本発明に係る水幕型防火防煙設備では、火災区画及び非火災区画の各々には、加圧手段によって空気を送り込むための給気口と排煙手段によって排気するための排煙口とが、少なくとも一箇所ずつ設けられていることが好ましい。
本発明では、火災が発生した火災区画に設けられている排煙口より煙や水蒸気を排気し、非火災区画内に設けられた給気口から加圧することができる。このように火災の発生箇所に応じて区画内の空気を加圧又は排気させることができる。 Further, in the water curtain type fire prevention and smoke prevention equipment according to the present invention, each of the fire compartment and the non-fire compartment has an air supply port for sending air by a pressurizing means and a smoke exhaust port for exhausting by a smoke exhaust means. Are preferably provided at least one place.
In the present invention, smoke and water vapor can be exhausted from a smoke outlet provided in a fire section where a fire has occurred, and pressurized from an air supply opening provided in a non-fire section. In this way, the air in the compartment can be pressurized or exhausted according to the location of the fire.

また、本発明に係る水幕型防火防煙設備では、加圧手段には加圧ファンが使用されていることが好ましい。
本発明では、火災時に加圧ファンを作動させることで、火災が発生していない非火災区画に空気を送ることができる。 In the water curtain type fireproof and smokeproof equipment according to the present invention, it is preferable that a pressure fan is used as the pressure means.
In the present invention, air can be sent to a non-fire section where no fire has occurred by operating the pressure fan during a fire.

また、本発明に係る防火防煙方法では、火災箇所を水幕で取り囲むことで火災区画を形成し、火災区画に水幕を介して隣接する非火災区画内を加圧手段によって空気を送り込むことで加圧すると同時に、火災区画内の空気を排煙手段によって排気するようにしたことを特徴としている。
本発明では、非火災区画を加圧手段によって加圧することで、水幕の内外の空間すなわち火災区画と非火災区画に圧力差が生じる。そして、空気が水幕の隙間を通過し、水幕の外方から内側の方向に気流が形成されることになる。したがって、火災区画で発生する煙や水蒸気は、水幕より外側に拡散されることはない。 Further, in the fire prevention and smoke prevention method according to the present invention, a fire section is formed by surrounding a fire spot with a water curtain, and air is sent into the non-fire section adjacent to the fire section via the water curtain by a pressurizing means. At the same time, the air in the fire compartment is exhausted by the smoke exhausting means.
In the present invention, a pressure difference is generated between the space inside and outside the water curtain, that is, the fire compartment and the non-fire compartment, by pressurizing the non-fire compartment with the pressurizing means. Then, air passes through the gap of the water curtain, and an air flow is formed from the outside to the inside of the water curtain. Therefore, smoke and water vapor generated in the fire compartment are not diffused outside the water curtain.

また、本発明に係る防火防煙方法では、排煙手段に排煙ファンを使用して、火災区画内を減圧することが好ましい。
本発明では、火災区画の空気を排煙ファンにより強制的に排気させることで、火災区画内で乱流や滞留を防止でき、周囲から加圧される気流と合わせて効率的な排煙を行えるよう空気の流れを形成することができる。 Moreover, in the fire prevention smoke prevention method which concerns on this invention, it is preferable to use a smoke exhaust fan for a smoke exhaust means, and to depressurize the inside of a fire division.
In the present invention, the air in the fire compartment is forcibly exhausted by the smoke exhaust fan, so that turbulence and stagnation can be prevented in the fire compartment, and efficient smoke exhaust can be performed together with the air flow pressurized from the surroundings. An air flow can be formed.

本発明の水幕型防火防煙設備及び防火防煙方法によれば、火災箇所を水幕で取り囲む火災区画と水幕の外側に隣接する非火災区画とに圧力差を生じさせて非火災区画から火災区画の方向に空気の流れを形成させることで、従来の防火効果や遮炎効果に加えて、遮煙性能を確保することができる。これにより、非火災区画では、煙や水蒸気の拡散により視界が遮られることがなく、避難や消火活動の安全性を向上させることができる。
また、本発明による水幕型防火防煙設備によれば、防煙機能を有することから、関係法令の基準を満たすことのできる適用範囲が、従来のように建築基準法における面積区画に限定されることはない。すなわち、関係法令における防煙性能に関する基準を満たすことが可能となり、例えば竪穴区画や異種用途区画にも本水幕型防火防煙設備の適用範囲を広げることが可能となる。 According to the water curtain type fire prevention and smoke prevention equipment and fire prevention and smoke prevention method of the present invention, a pressure difference is generated between a fire compartment that surrounds a fire spot with a water curtain and a non-fire compartment adjacent to the outside of the water curtain, thereby providing a non-fire compartment. By forming an air flow in the direction of the fire compartment, it is possible to ensure smoke insulation performance in addition to the conventional fire prevention effect and flame insulation effect. Thereby, in non-fire sections, the visibility is not obstructed by the diffusion of smoke and water vapor, and the safety of evacuation and fire fighting activities can be improved.
Further, according to the water curtain type fire prevention and smoke prevention equipment according to the present invention, since it has a smoke prevention function, the applicable range capable of satisfying the standards of related laws and regulations is limited to the area sections in the Building Standard Law as in the past. Never happen. That is, it becomes possible to satisfy the standards related to smoke prevention performance in the relevant laws and regulations, and for example, it is possible to expand the application range of the water curtain type fire prevention and smoke prevention equipment to a pothole section or a different use section.

以下、本発明の実施の形態による水幕型防火防煙設備及び防火防煙方法について、図１に基づいて説明する。
図１は実施の形態による防火防煙設備を示す図である。 Hereinafter, a water curtain type fire and smoke prevention equipment and a fire and smoke prevention method according to an embodiment of the present invention will be described with reference to FIG.
FIG. 1 is a diagram showing a fire prevention and smoke prevention equipment according to an embodiment.

図１に示すように、本実施の形態による防火防煙設備１は、建物２内のフロア毎に、例えば建築基準法における面積区画などに則って設置されている。
防火防煙設備１は、天井２ａの所定位置に配された複数の噴出口３１、３２から水幕４１、４２を形成させる水幕型防火設備３と、水幕４１、４２によって仕切られた区画Ｒ内に空気を送り込んで加圧する加圧手段５と、区画Ｒ内から建物２外に排気させるための排煙手段６とから概略構成されている。
ここで、図１では水幕４１、４２を二箇所としているが、建物２の各フロアを所定範囲で区画できるように複数の水幕４を形成させていることが好ましい。 As shown in FIG. 1, the fire and smoke prevention equipment 1 according to the present embodiment is installed for each floor in a building 2 according to, for example, an area division in the Building Standard Law.
The fire prevention and smoke prevention equipment 1 includes a water curtain type fire prevention equipment 3 that forms water curtains 41 and 42 from a plurality of outlets 31 and 32 arranged at predetermined positions on the ceiling 2a, and a partition partitioned by the water curtains 41 and 42. A pressurizing means 5 for sending air into R and pressurizing it, and a smoke exhausting means 6 for exhausting the air from inside the section R to the outside of the building 2 are roughly configured.
Here, although two water curtains 41 and 42 are provided in FIG. 1, it is preferable to form a plurality of water curtains 4 so that each floor of the building 2 can be partitioned within a predetermined range.

加圧手段５は、各区画Ｒ内の所定箇所に所定数配設された給気口５ａと、給気口５ａに配管などによって連結して各区画Ｒを加圧させる加圧ファン５ｂとからなる。
また、排煙手段６は、各区画Ｒ内の所定箇所に所定数配設された排煙口６ａと、排煙口６ａに配管などによって連結して各区画Ｒ内の空気を強制的に排気させる排煙ファン６ｂとからなる。 The pressurizing means 5 includes an air supply port 5a disposed at a predetermined position in each compartment R, and a pressure fan 5b that pressurizes each compartment R by being connected to the air supply port 5a by piping or the like. Become.
Further, the smoke exhausting means 6 is connected to the smoke exhaust ports 6a disposed at a predetermined location in each compartment R by a pipe or the like and forcibly exhausts the air in each compartment R. And a smoke exhaust fan 6b.

次に、本実施の形態による防火防煙設備１による作用について図面に基づいて説明する。
図１に示す建物２内のフロアは、図中右端に避難用などとして使用される階段Ｓがあり、この階段Ｓに面して廊下があり、そして入口を介して居室などのスペースとなる間取りになっている。
図１に示すように、水幕型防火設備３の噴出口３１、３２の間の区画Ｒ内で火災（この箇所を火災箇所Ｂとする）があったときに、この噴出口３１、３２から放水されて水幕４１、４２が形成される。このときの各区画Ｒは、火災箇所Ｂを含んで形成されている火災区画Ｆと、この火災区画Ｆに水幕４１、４２を介して隣接されている非火災区画Ｍ、Ｎとからなる。
この火災区画Ｆ内では、火災箇所Ｂから煙Ｔが発生し、水幕４１、４２の火災区画Ｆ側の面で高温の影響により水蒸気Ｗが生じている。 Next, the effect | action by the fire prevention smoke prevention equipment 1 by this Embodiment is demonstrated based on drawing.
The floor in the building 2 shown in FIG. 1 has a staircase S that is used for evacuation, etc. at the right end in the figure. There is a corridor facing the staircase S, and a floor space that becomes a space such as a living room through the entrance. It has become.
As shown in FIG. 1, when there is a fire in the section R between the jet outlets 31 and 32 of the water curtain type fire prevention equipment 3 (this part is referred to as a fire spot B), Water curtains 41 and 42 are formed by discharging water. Each section R at this time includes a fire section F formed including the fire spot B and non-fire sections M and N adjacent to the fire section F via the water curtains 41 and 42.
In the fire section F, smoke T is generated from the fire spot B, and water vapor W is generated on the surface of the water curtains 41 and 42 on the fire section F side due to high temperature.

図１に示すように、水幕４１、４２の形成と同時に、加圧ファン５ｂを作動させて給気口５ａから非火災区画Ｍ、Ｎに空気を送り込むと、非火災区画Ｍ、Ｎ内が加圧されて第一圧力Ｐ１となる。さらに、排煙ファン６ｂを作動させると、火災区画Ｆに充満されている煙Ｔや水蒸気Ｗは強制的に排煙口６ａから屋外に排気される。これにより、火災区画Ｆは、減圧されて第二圧力Ｐ２となる。   As shown in FIG. 1, simultaneously with the formation of the water curtains 41 and 42, when the pressure fan 5b is operated to send air from the air supply port 5a to the non-fire compartments M and N, the inside of the non-fire compartments M and N The pressure is increased to the first pressure P1. Further, when the smoke exhaust fan 6b is operated, the smoke T and the water vapor W filled in the fire section F are forcibly exhausted from the smoke exhaust port 6a to the outside. Thereby, the fire section F is depressurized and becomes the second pressure P2.

そして、火災区画Ｆと非火災区画Ｍ、Ｎとの間に圧力差ΔＰ（Ｐ１−Ｐ２）が生じる。このとき、第一圧力Ｐ１は第二圧力Ｐ２より大きくなることから、非火災区画Ｍ、Ｎから火災区画Ｆの方向に気流（図１に示す矢印Ｅ）が生じる。ここで、水幕４１、４２は、水幕自体が隙間を有していることから、この隙間を空気が通過することになるが、上述した気流の向きとなるため、火災区画Ｆ内の煙Ｔや水蒸気Ｗは、非火災区画Ｍ、Ｎに侵入して拡散することがない。このため、例えば避難する人は、非火災区画Ｍ、Ｎを通って安全に避難することができる。
なお、火災区画Ｆ内は、強制排気されることで乱流や滞留を防止でき、非火災区画Ｍ、Ｎから加圧される気流と合わせて効率的な排煙が行えるよう空気の流れを形成することができる。 And pressure difference (DELTA) P (P1-P2) arises between the fire division F and the non-fire divisions M and N. FIG. At this time, since the first pressure P1 is larger than the second pressure P2, an air flow (arrow E shown in FIG. 1) is generated in the direction from the non-fire sections M and N to the fire section F. Here, since the water curtains 41 and 42 have gaps, the air passes through the gaps. T and water vapor W do not enter and diffuse into the non-fire sections M and N. For this reason, for example, the person who evacuates can evacuate safely through the non-fire sections M and N.
The fire compartment F can be forced to exhaust to prevent turbulence and stagnation, and an air flow is formed so that efficient smoke discharge can be performed together with the air flow pressurized from the non-fire compartments M and N. can do.

上述した本実施の形態による水幕型防火防煙設備及び防火防煙方法では、非火災区画Ｍ、Ｎと火災区画Ｆとに圧力差ΔＰを生じさせて非火災区画Ｍ、Ｎから火災区画Ｆ側の方向に空気の流れを形成させることで、従来の遮炎性能に加えて、遮煙性能を確保することができる。これにより、非火災区画Ｍ、Ｎでは、煙Ｔや水蒸気Ｗの拡散により視界が遮られることがなく、避難や消火活動の安全性を向上させることができる。
また、本実施の形態による防火防煙設備１は、防煙機能を有することから、関係法令の基準を満たすことのできる適用範囲が、従来のように建築基準法における面積区画に限定されることはない。すなわち、関係法令における防煙性能に関する基準を満たすことが可能となり、例えば吹き抜け、階段室、エレベータシャフト、ダクトスペースなどの竪穴区画や、劇場、映画館、マーケット、ホテルなどの異種用途区画にも防火防煙設備１の適用範囲を広げることが可能となる。 In the water curtain type fire and smoke prevention equipment and fire prevention and smoke prevention method according to the above-described embodiment, a pressure difference ΔP is generated between the non-fire compartments M and N and the fire compartment F so that the non-fire compartments M and N to the fire compartment F. By forming the air flow in the direction of the side, in addition to the conventional flame shielding performance, it is possible to ensure the smoke shielding performance. Thereby, in the non-fire sections M and N, the visibility is not blocked by the diffusion of the smoke T and the water vapor W, and the safety of evacuation and fire fighting activities can be improved.
Moreover, since the fire prevention smoke prevention equipment 1 by this Embodiment has smoke prevention function, the applicable range which can satisfy | fill the standard of related laws and regulations is limited to the area division in a building standard law like before. There is no. In other words, it is possible to meet the standards related to smoke-proof performance in the relevant laws and regulations, for example, pits such as atriums, staircases, elevator shafts, duct spaces, etc. and fire-proof areas such as theaters, movie theaters, markets, hotels, etc. The application range of the smoke-proof equipment 1 can be expanded.

以上、本発明による水幕型防火防煙設備及び防火防煙方法の実施の形態について説明したが、本発明は上記の実施の形態に限定されるものではなく、その趣旨を逸脱しない範囲で適宜変更可能である。
例えば、本実施の形態では排煙手段６に排煙ファン６ｂを使用しているが、これに限定されることはない。例えば、排煙ファン６ｂを設けずに、自然排煙や一定の圧力が加わったときに開放される圧力逃がし口などの排煙口６ａによって煙Ｔや水蒸気Ｗを屋外に逃がす方法であってもかまわない。
また、本実施の形態における火災区画Ｆの範囲は、図１に示すように一箇所の区画Ｒとしているが、これに限定されず、例えば火災箇所Ｂの範囲が広い場合には複数の区画Ｒを水幕４で取り囲んで一つの火災区画Ｆを形成してもかまわない。
また、水幕型防火設備３は、ドレンチャー設備以外に、水を幕状に又は紡錘状に形成できる水を噴水できる機構が適宜用いられる。 As mentioned above, although the embodiment of the water curtain type fire prevention smoke prevention equipment and fire prevention smoke prevention method by this invention was described, this invention is not limited to said embodiment, In the range which does not deviate from the meaning, it is appropriate. It can be changed.
For example, although the smoke exhausting fan 6b is used for the smoke exhausting means 6 in this Embodiment, it is not limited to this. For example, even if the smoke exhaust fan 6b is not provided, the smoke T and the water vapor W are released to the outdoors through the smoke exhaust port 6a such as a pressure release port that is released when natural smoke or a certain pressure is applied. It doesn't matter.
Further, the range of the fire section F in the present embodiment is one section R as shown in FIG. 1, but is not limited to this. For example, when the range of the fire section B is wide, a plurality of sections R May be surrounded by a water curtain 4 to form one fire section F.
In addition to the drainage equipment, the water curtain type fire prevention equipment 3 appropriately employs a mechanism that can fountain water that can form water in a curtain shape or a spindle shape.
