Description
本考案は、地下街、駅構内、市役所、一般ビル等建物内などの床面に設置し、非常口又は出口がある方向を避難者に示す用途に用いて好適な誘導標識に関する。 The present invention relates to a guide sign that is suitable for use in applications such as an underground mall, a station premises, a city hall, a building such as a general building, and the like that indicates an evacuee with the direction of an emergency exit or exit.
地下街や地下鉄駅構内または災害発生時に避難が必要とされる場所などには、非常口や出口がある方向を示す避難誘導灯が万一の災害に備えて設置されている。 Evacuation guide lights indicating the direction of emergency exits and exits are installed in case of an emergency in underground malls, subway stations, or places where evacuation is required in the event of a disaster.
この避難誘導灯は、災害時に停電が発生しても点灯を維持し、避難者に出口や非常口がある方向を知らせるという非常に重要な役割を持つ。例えば、火災の影響で停電が発生し、地下鉄駅構内が真っ暗になった場合、避難者は暗闇の中で避難誘導灯の案内表示を頼りに避難する。このため、避難誘導灯は通路の天井から吊り下げられたり、あるいは非常口付近の壁などに目立つように設置されたりしている。 This evacuation guide light has a very important role of maintaining the lighting even if a power failure occurs in the event of a disaster and notifying the refugees of the direction of exits and emergency exits. For example, if a power outage occurs due to a fire and the inside of a subway station becomes completely dark, the evacuees evacuate in the dark relying on the guidance display of the evacuation guide light. For this reason, the evacuation guide light is hung from the ceiling of the passage or installed prominently on the wall near the emergency exit.
しかしながら、火災が発生すると煙が上方に立ち昇って天井に蔓延し、避難誘導灯が煙で覆われてしまうため、避難者は避難誘導灯を見つけることができず、非常口等にたどり着けないという問題が起こり得る。さらに、停電時に地下鉄駅構内などで唯一点灯している避難誘導灯が火災時の煙で覆い隠されてしまうと、通路もしくは建造物内が暗くなり、避難者は視界不良で避難できなくなる。特に階段付近ではパニックに陥る危険がある。又避難誘導灯その物が火災等で故障し避難できなくなった事故も報道されている。 However, when a fire breaks out, smoke rises and spreads on the ceiling, and the evacuation guide light is covered with smoke, so the refugee cannot find the evacuation guide light and cannot reach the emergency exit. Can happen. Furthermore, if the evacuation guide light that is only lit at the time of a power outage is covered with smoke from the fire, the passage or the building becomes dark, and the refugee cannot evacuate due to poor visibility. There is a risk of panic, especially near the stairs. There have also been reports of accidents in which the evacuation guide light itself has failed due to fire or other reasons.
このような問題を解消する誘導標識が、下記特許文献に開示されている。
これらは、床に設置することが可能で、地下鉄駅構内や地下街等において照明が点灯していて明るい普段の時に、通行人が敷設材のガラス板に描かれた誘導標識を視認することができるだけでなく、停電が発生して通路が暗闇になった時は、ガラス板の裏面の蓄光性塗料が塗布されている領域がりん光するため、避難者は暗闇の中でも誘導標識を容易に視認することができる。また、裏面側から照明を当てる照明器具及びその配線を床面内に埋設する必要がないので安価なので容易に数多く設置でき、故障も少なく維持コストが非常に安いという利点を有する。
Inductive labels that solve such problems are disclosed in the following patent documents.
These can be installed on the floor, and the lights can be seen on subway stations and underground shopping streets, so that passers-by can only see the guidance signs drawn on the glass plate of the laying material when it is bright and normal. In addition, when a power outage occurs and the passage is dark, the area where the phosphorescent paint is applied on the back side of the glass plate is phosphorescent, so evacuees can easily see the guidance sign even in the dark. be able to. Further, since it is not necessary to embed a lighting fixture and its wiring from the back side in the floor, it is inexpensive and can be easily installed in large numbers.
この種の誘導標識は、蓄光性塗料を用いるものであるが、蓄光性塗料は水に弱いという問題がある。蓄光性塗料を含む着色層に水分が浸入すると、蓄光性塗料の蓄光性能が著しく劣化し、誘導標識を早期に交換しなければならず、コスト高となる。 This type of guide sign uses a phosphorescent paint, but there is a problem that the phosphorescent paint is vulnerable to water. When moisture enters the colored layer containing the phosphorescent paint, the phosphorescent performance of the phosphorescent paint is remarkably deteriorated, and the guide sign must be replaced early, resulting in high costs.
前記特許文献１では、最下層の被覆層の外周縁を上方に折り曲げて着色層の側面を覆い、水分が蓄光性塗料に接触するのを防止しようとしているが、このような構成では到底水分の侵入を完全に長期間防ぐことはできなかった。 In Patent Document 1, the outer peripheral edge of the lowermost coating layer is bent upward to cover the side surface of the colored layer to prevent moisture from coming into contact with the phosphorescent paint. The intrusion could not be completely prevented for a long time.
前記特許文献２では、ガラスコーティングで着色層の外周部を覆い、水分が蓄光性塗料に接触するのを防止しようとしているが、ガラスコーティングにはピンホールが発生しやすく、繰り返しピンホール内に水分が侵入することでガラスコーティングが劣化し、次第にガラスコーティングに亀裂が生じ、ついには水分が着色層に侵入してしまうという問題がある。 In Patent Document 2, the outer periphery of the colored layer is covered with glass coating to prevent moisture from coming into contact with the phosphorescent paint. However, pinholes are likely to occur in the glass coating, and moisture is repeatedly contained in the pinhole. As a result, the glass coating deteriorates, and the glass coating gradually cracks, so that moisture eventually enters the colored layer.
本考案は、水分が着色層に侵入するのを完全に防止し、蓄光性塗料の性能劣化を防いで耐久性の優れた誘導標識を開発することを課題とするものである。 It is an object of the present invention to develop a guidance sign having excellent durability by completely preventing moisture from entering a colored layer and preventing performance deterioration of a phosphorescent paint.
本考案は、透明なガラス層と、その裏面に形成され蓄光性塗料と一般塗料を含む着色層と、その背面に形成され液体及び空気を通さない被覆層を有する板状の誘導標識であって、
外周部に塗布した樹脂のシール材によって前記着色層の外周部が密封されていることを特徴とする誘導標識である。（請求項１）
The present invention is a plate-shaped guide sign having a transparent glass layer, a colored layer formed on its back surface and containing a phosphorescent paint and a general paint, and a coating layer formed on its back surface that is impermeable to liquid and air. ,
The guide mark is characterized in that the outer peripheral portion of the colored layer is sealed by a resin sealing material applied to the outer peripheral portion. (Claim 1)
透明なガラス層は、蓄光性能を高めるために紫外線の透過率が８５％以上、標識の視認性を高めるために可視光の透過率が９０％以上の高透過ガラスを用いることが望ましい。 For the transparent glass layer, it is desirable to use a highly transmissive glass having an ultraviolet transmittance of 85% or more in order to improve the luminous performance and a visible light transmittance of 90% or more in order to improve the visibility of the sign.
着色層における蓄光性塗料は、市販のものを使用できる。廊下又は通路に設ける高輝度蓄光式誘導標識の基準を規定した消防庁告示改正（平成１８年３月２９日改正）によると、ＪＩＳＺ９１０７の蛍光ランプＤ６５により照度２００ルクスの外光を２０分間照射し、その後２０分経過した後における表示面が１００ミリカンデラ／ｍ2以上の平均輝度を有する必要があるので、これに適合するものを使用することが望ましい。
着色層における一般塗料は、蓄光性を有しない任意の塗料を使用できる。
A commercially available thing can be used for the luminous paint in a colored layer. According to the Fire and Disaster Management Agency Notification Revision (Revised March 29, 2006), which stipulates the standards for high-intensity phosphorescent guidance signs provided in hallways or passages, illuminates 200 lux of external light for 20 minutes with the fluorescent lamp D65 of JISZ9107. Since the display surface after 20 minutes has to have an average luminance of 100 millicandelas / m 2 or more after that, it is desirable to use a display that conforms to this.
As the general paint in the colored layer, any paint having no phosphorescent property can be used.
被覆層は、水と空気を通さない金属、樹脂、ガラス製などとすることができるが、強度と耐久性を考慮してステンレスなどの金属製とすることが望ましい。 The coating layer can be made of a metal, resin, glass, or the like that is impermeable to water and air, but is preferably made of a metal such as stainless steel in consideration of strength and durability.
本考案において、シール材を形成する樹脂は、水分の侵入を防ぐものであれば特に限定されないが、施工性及び長期間耐久性に優れた２液性エポキシ樹脂とすることができる。（請求項２） In the present invention, the resin forming the sealing material is not particularly limited as long as it prevents moisture from entering, but a two-component epoxy resin excellent in workability and long-term durability can be used. (Claim 2)
本考案において、前記着色層の周縁が前記ガラス層及び被覆層の周縁よりも内側に引っ込んでいることで該ガラス層と被覆層の周縁の間に凹部が形成され、該凹部内に前記シール材を充填することができる。（請求項３） In the present invention, a concave portion is formed between the peripheral edge of the glass layer and the coating layer because the peripheral edge of the colored layer is recessed inward from the peripheral edges of the glass layer and the coating layer, and the sealing material is formed in the concave portion. Can be filled. (Claim 3)
この場合、前記ガラス層の周縁下端に接触面を多く取るために面取りを形成しておくことができる。（請求項４） In this case, chamfering can be formed in order to increase the contact surface at the lower end of the periphery of the glass layer. (Claim 4)
このようにすることで、シール材におけるシール効果が高まると共に、シール材が剥がれにくくなるので、誘導標識が製造されてから設置されるまでの間に、外周部が擦れたり、衝撃を受けたとしても、シール効果に影響を与えることが無く、品質が保たれる。 By doing so, the sealing effect in the sealing material is enhanced and the sealing material is difficult to peel off, so that the outer periphery is rubbed or impacted between the time when the guide sign is manufactured and installed. However, the quality is maintained without affecting the sealing effect.
本考案の誘導標識は、その外周部に樹脂のシール材を充填することで着色層の外周部が密封されているので、水分が着色層に浸入して蓄光性塗料が劣化するのを完全に防止することができる。 Since the outer periphery of the colored layer is hermetically sealed by filling the outer periphery with a resin sealing material, the inductive sign of the present invention completely prevents moisture from entering the colored layer and deteriorating the phosphorescent paint. Can be prevented.
以下、本考案の実施形態を、図面を参照して説明する。
図１は本考案の実施形態に係る誘導標識１の平面図、図２は部分断面図である。
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a plan view of a guide sign 1 according to an embodiment of the present invention, and FIG. 2 is a partial cross-sectional view.
誘導標識１は、図２に示すように、表面のガラス層２、その裏面に形成された着色層３、その裏面に形成された白反射層４、さらにその裏面に形成された被覆層５、及び外周部の全周に充填されたシール材６からなる。 As shown in FIG. 2, the guide sign 1 includes a front glass layer 2, a colored layer 3 formed on the back surface, a white reflective layer 4 formed on the back surface, and a coating layer 5 formed on the back surface. And a sealing material 6 filled in the entire outer periphery.
厚さ６ｍｍのガラス層２は、例えば米国ＰＰＧ社製の商品名「スターファイアー」を使用できる。ＰＰＧ社のデータシートによれば、同社製のフロート板ガラス（青板ガラスと称される普通ガラス）の場合は板厚６ｍｍにおいて紫外線透過率が５０．３％、可視光透過率が８７．９％であるが、高透過ガラス「スターファイアー」の場合は板厚６ｍｍで紫外線透過率が８６％、可視光透過率が９１％である。このように高透過ガラスは普通ガラスの紫外線及び可視光透過率に比べて格段に高い。
ガラス層２の外周縁下端には面取り２ａが形成されている。
For the glass layer 2 having a thickness of 6 mm, for example, the trade name “Starfire” manufactured by PPG, USA can be used. According to the PPG data sheet, the company's float plate glass (ordinary glass called blue plate glass) has an ultraviolet transmittance of 50.3% and a visible light transmittance of 87.9% at a thickness of 6 mm. However, the high transmission glass “Starfire” has a plate thickness of 6 mm, an ultraviolet transmittance of 86%, and a visible light transmittance of 91%. Thus, the high transmission glass is much higher than the ultraviolet and visible light transmittance of ordinary glass.
A chamfer 2 a is formed at the lower end of the outer peripheral edge of the glass layer 2.
厚さ１．５ｍｍの着色層３は、蓄光性塗料３ａ、一般塗料３ｂからなる。図２に示すように、一般塗料３ｂは、蓄光性塗料３ａの上に部分的に厚さ０．０５ｍｍで塗布されている。図１において、網掛けで描かれている、避難口であることを示すシンボル、及び避難の方向を示すシンボルの部分は、緑色の一般塗料３ｂが塗布されている部分である。背景部分には一般塗料３ｂが塗布されていないので、淡い黄緑色の蓄光性を有する塗料が視認される。このような緑色の一般塗料と淡い黄緑色の蓄光性塗料とによって着色層３が形成されている。 The colored layer 3 having a thickness of 1.5 mm includes a luminous paint 3a and a general paint 3b. As shown in FIG. 2, the general paint 3b is partially applied to the luminous paint 3a with a thickness of 0.05 mm. In FIG. 1, a symbol indicating an evacuation exit and a symbol portion indicating the evacuation direction, which are drawn by shading, are portions to which the green general paint 3 b is applied. Since the general paint 3b is not applied to the background portion, a pale yellow-green paint having a phosphorescent property is visually recognized. The colored layer 3 is formed of such a general green paint and a light yellow-green phosphorescent paint.
蓄光性塗料は、例えば根本特殊化学株式会社製の商品名「ルミノーバ」を用いることができる。 As the phosphorescent paint, for example, trade name “Luminova” manufactured by Nemoto Special Chemical Co., Ltd. can be used.
着色層３の裏面には、白反射層４が設けられている。白反射層４は厚さ０．０５ｍｍの白インキの層である。白反射層で光が反射するのでより蓄光が高まり輝度値が高くなるので、標識の視認性が高まる。 A white reflective layer 4 is provided on the back surface of the colored layer 3. The white reflective layer 4 is a white ink layer having a thickness of 0.05 mm. Since light is reflected by the white reflection layer, the accumulated light is increased and the luminance value is increased, so that the visibility of the sign is increased.
白反射層４の裏面は、被覆層５で覆われている。被覆層は厚さ０．２ｍｍのステンレス板である。 The back surface of the white reflective layer 4 is covered with a coating layer 5. The coating layer is a stainless steel plate having a thickness of 0.2 mm.
着色層３と白反射層４の周縁は、ガラス層２及び被覆層５の周縁よりも内側に引っ込んでいて、ガラス層２と被覆層５の周縁の間に凹部が形成され、この凹部の中にシール材６が塗布・充填され、これにより着色層３と白反射層４が密封されている。
シール材６は２液性エポキシ樹脂で、塗布・充填後約２４時間で硬化し、４８時間以上になると固体化し、耐水性・耐薬品性に非常に優れている。
The peripheral edges of the colored layer 3 and the white reflective layer 4 are recessed more inside than the peripheral edges of the glass layer 2 and the coating layer 5, and a recess is formed between the peripheral edges of the glass layer 2 and the cover layer 5. The sealing material 6 is applied / filled to seal the colored layer 3 and the white reflective layer 4.
The sealing material 6 is a two-component epoxy resin that cures in about 24 hours after application and filling, and solidifies after 48 hours or more, and is extremely excellent in water resistance and chemical resistance.
誘導標識１は、床面に対してセメント、接着剤、両面テープなど任意の手段で固定される。 The guide sign 1 is fixed to the floor surface by any means such as cement, adhesive, double-sided tape.
地下鉄駅構内や地下街等において照明が点灯していて明るい普段の時に、通行人が誘導標識１の着色層に緑色で描かれた絵柄や文字を視認することができる。一方、地下鉄駅構内や地下街等で停電が発生して通路が暗闇になった時は、一般塗料が塗布されていない蓄光性塗料の背景部分がりん光する。この結果、避難口であることを示すシンボル、避難の方向を示すシンボルと、これら以外の背景部分との間に明暗の差が生じ、避難者は暗闇の中でも誘導標識１を容易に視認することができる。 When the lights are lit in a subway station yard or underground shopping street, a passer-by can see a pattern or characters drawn in green on the colored layer of the guide sign 1. On the other hand, when a power outage occurs in a subway station or underground mall, and the passage becomes dark, the background portion of the phosphorescent paint to which general paint is not applied is phosphorescent. As a result, there is a difference in light and darkness between the symbol indicating the exit, the symbol indicating the direction of evacuation, and the background portion other than these, and the refugee can easily visually recognize the guide sign 1 even in the dark. Can do.
また、誘導標識１を床面に設置することにより、火災が発生して停電したときに、火災によって発生した煙が通路の上方に蔓延していても、避難者は床の誘導標識１を容易に発見することができる。さらに、避難者は火災によって発生した煙を吸わないよう屈んだ状態で誘導標識１を見ながら避難できるので、防災上の安全性を高めることができる。 In addition, by installing the guide sign 1 on the floor, when a fire occurs and a power failure occurs, even if smoke generated by the fire spreads above the passage, evacuees can easily use the guide sign 1 on the floor Can be found in. Furthermore, since the evacuees can evacuate while looking at the guide sign 1 in a bent state so as not to smoke the smoke generated by the fire, safety for disaster prevention can be improved.
さらに、誘導標識１はガラス面の裏面の着色層に絵柄が描かれているので、床面に設置された場合、通行人が誘導標識１を繰り返し踏んでも着色層まで摩滅することはない。そのため、床面に設置して長期にわたって使用しても誘導標識１の表示機能が損なわれないので、長期間交換する必要がない。また、停電時などは蓄光性塗料によってりん光するようになっているので、裏面側から照明を当てる照明器具及び、その電線用配管を床面内に埋設する必要がない。そのため誘導標識１の設置費用やスペースを大幅に低減することができる。 Further, since the guide sign 1 has a pattern drawn on the colored layer on the back side of the glass surface, even if the passerby repeatedly steps on the guide sign 1 when it is installed on the floor surface, the colored sign layer will not wear out. Therefore, even if it is installed on the floor and used for a long time, the display function of the guide sign 1 is not impaired, so it is not necessary to replace it for a long time. Moreover, since it is phosphorescent by the phosphorescent paint at the time of a power failure etc., it is not necessary to embed the lighting fixture which illuminates from a back surface side, and its electric wire piping in a floor surface. Therefore, the installation cost and space for the guide sign 1 can be greatly reduced.
また、表面のガラス層は高透過ガラスなので、前述したように、蓄光材料の蓄光に必要な紫外線の透過率が８５％以上あり、同じ厚さで紫外線透過率が５０％程度の普通ガラスと比べて非常に高い。このため、蓄光性塗料の蓄光が短時間に行える。その上、高透過ガラスの可視光透過率は９０％以上あり、同じ厚さで可視光透過率が８５％程度の普通ガラスと比べて高い。このため、蓄光性塗料によるりん光輝度（光を当て消した後の輝度）が普通ガラスを通した場合よりも高くなる。このような光透過性能を持つので、省電力のために明るさを落としているような薄暗い所に設置されても、蓄光性塗料が効率良く紫外線を吸収し、停電時に十分なりん光輝度を生じさせることができる。なお、廊下又は通路に設ける高輝度蓄光式誘導標識の基準を規定した消防庁告示改正（平成１８年３月２９日改正）では、ＪＩＳＺ９１０７の蛍光ランプＤ６５により照度１００ルクスの外光を２０分間照射し、その後２０分経過した後における表示面が１５０ミリカンデラ／ｍ2以上の平均輝度があれば、設置環境照度が１２８Ｌｘ以上あれば設置できることになっている。したがって、上記のような光透過性能を持つ誘導標識１は、省電力のために２００ルクスの明るさがとれないような暗い場所でも使用可能になる。 In addition, since the glass layer on the surface is a highly transmissive glass, as described above, the transmittance of ultraviolet rays necessary for the phosphorescence of the phosphorescent material is 85% or more, compared with ordinary glass having the same thickness and an ultraviolet transmittance of about 50%. And very expensive. For this reason, the phosphorescent paint can be stored in a short time. In addition, the high transmittance glass has a visible light transmittance of 90% or more, which is higher than that of ordinary glass having the same thickness and a visible light transmittance of about 85%. For this reason, the phosphorescence luminance (luminance after erasing light) by the phosphorescent paint is higher than that when passing through ordinary glass. With such light transmission performance, even if it is installed in a dim place where the brightness is reduced to save power, the phosphorescent paint efficiently absorbs ultraviolet rays, and the brightness is sufficiently bright during a power failure. Can be generated. In addition, in the Fire Department Notification Revision (revised on March 29, 2006) that stipulates the standards for high-intensity phosphorescent guidance signs provided in hallways or passages, external light with an illuminance of 100 lux is irradiated for 20 minutes by the fluorescent lamp D65 of JISZ9107. If the display surface after 20 minutes thereafter has an average luminance of 150 millicandelas / m 2 or more, the display can be installed if the installation environment illuminance is 128 Lx or more. Therefore, the guide sign 1 having the light transmission performance as described above can be used in a dark place where the brightness of 200 lux cannot be obtained for power saving.
本実施形態における絵柄（避難口であることを示すシンボル、及び避難の方向を示すシンボル）は一例であって、状況に応じて種々の絵柄を採用できることはもちろんである。 The pattern (a symbol indicating an evacuation exit and a symbol indicating the direction of evacuation) in the present embodiment is an example, and it is a matter of course that various patterns can be adopted depending on the situation.
