Description

  The present invention relates to a laying material with a guide sign that is installed on a floor surface in an underground shopping center, a subway station, or the like and indicates an evacuee with the direction of an emergency exit or exit.

  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.

  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 the 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.

  However, when a fire occurs, smoke rises upward 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 etc. 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.

  As an evacuation guide light that solves such a problem, Japanese Patent Application Laid-Open No. 4-309198 and Japanese Patent Application Laid-Open No. 2005-32445 propose an evacuation guide light that can be embedded in the floor surface. Generally, instructed to evacuate the floor by lowering the posture so as not to inhale the upper smoke during a fire, the refugee evacuates in a bent state. Therefore, if an evacuation guide light is embedded in the floor as disclosed in the above publication, it can be expected that the guide light will be immediately noticeable and easily reach the exit when evacuating.

  However, there are the following problems when evacuation guide lights are buried on the floor surface.

  It is necessary to embed a lighting fixture that illuminates from the back side of the guide sign plate provided on the same surface as the floor, and an electric pipe for lighting the lighting fixture in the floor. It's tedious. In addition, there is a risk of water entering the main body of the guide light due to cleaning or the like, resulting in failure.

  In the first place, since the fluorescent lamp lamp is housed in the main body of the evacuation guide lamp, the fluorescent lamp lamp needs to be replaced when the fluorescent lamp lamp is burned out. It also takes power from constant lighting. Furthermore, due to the long-term use, the letters and pictures on the guide sign board are discolored by the heat of the fluorescent lamp, and the display effect is reduced. Since a space for accommodating a storage battery and wiring is required in the guide light body, the guide light body becomes large. The built-in storage battery must be inspected at regular intervals. There is a drawback that evacuation guidance cannot be performed when the battery does not turn on at the time of a power failure due to a failure or a battery shortage. In particular, evacuation guide lights are installed at certain intervals in the direction of emergency exits, etc., so when several guide lights do not blink due to a failure or other reasons along the evacuation route to emergency exits, etc. When is discolored, deformed or damaged, evacuees cannot reach emergency exits.

  Accordingly, an object of the present invention is to provide a laying material with a guide sign that can be installed at a low cost and does not have a concern about a failure or a display function deterioration of the guide sign.

  In order to achieve the above object, the laying material with a guide sign according to the present invention has a high transmission glass and a colored layer formed on the back surface of the high transmission glass. It is drawn so as to be visible from the surface side of the transmissive glass. The colored layer is formed by drawing a guide sign with a general paint and a phosphorescent paint of a predetermined color on the back surface of the high transmission glass.

  According to the configuration of the present invention, since the glass plate on which the induction sign is drawn is not a normal glass called blue plate glass but a high transmission glass, the color tone of the induction sign drawn on the back surface of the glass is the glass plate. Hard to change from the front side. In other words, when letters and designs of guide signs are printed in the prescribed color tone on the back side of ordinary glass with a bluish tint, it looks dull and the tone of the guide sign drawn on the back side of the glass changes. End up. Since the color of the guide sign is defined by JIS (Japanese Industrial Standard), it is difficult to adjust the color tone when the guide sign visually recognized from the glass surface side is drawn on the back surface of the normal glass. On the other hand, in the present invention, since a highly transmissive glass that does not have a tint is used, such a problem hardly occurs.

  In addition, according to the present invention, when the lights are lit in the subway station premises and underground shopping streets, etc., it is not only possible for the passers-by to see the guidance sign drawn on the glass plate of the laying material, but also the power failure When this occurs and the passage becomes dark, the area where the phosphorescent paint is applied on the back side of the glass plate is phosphorescent, so the evacuees can easily see the guidance sign even in the dark.

  Furthermore, since the laying material of the present invention is installed on the floor surface, when a fire occurs and a power failure occurs, even if smoke generated by the fire spreads above the passage, Inducible labels can be easily found. The evacuees can evacuate while looking at the guidance signs in a bent state so as not to smoke the smoke generated by the fire.

  In the laying material of the present invention, since the guide sign can be visually recognized by the phosphorescent paint even in the dark, it is not necessary to embed a lighting fixture and its wiring for illuminating the laying material from the back side in the floor surface. Therefore, it is possible to greatly reduce the installation cost and space for the laying material.

  Since the guide sign is drawn on the back side of the glass plate, the guide sign will not wear out even if a passerby steps on the glass plate surface of the laying material installed on the floor of a subway station or underground mall. Therefore, even if the laying material of the present invention is installed on the floor and used for a long period of time, it does not need to be frequently replaced because the display function of the guidance sign is not impaired.

  In addition, highly transmissive glass with an induction sign drawn on the back using a phosphorescent paint has an ultraviolet transmittance of 70% or more necessary for the phosphorescence of the phosphorescent material, and the ordinary thickness is about 50% with the same thickness. Very high compared to glass. For this reason, phosphorescence of the phosphorescent paint applied to the back surface of the high transmission glass can be performed 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. Because it has such light transmission performance, even if it is installed in a dim place where the brightness is reduced for power saving, it can absorb a lot of ultraviolet rays in the phosphorescent paint, and it will have a sufficient brightness in the event of a power failure. Can be generated.

  Furthermore, the laying material preferably further includes a coating layer that covers the colored layer and prevents the liquid and air from passing through the colored layer. Since the phosphorescent paint is significantly deteriorated by moisture, the colored layer, which is part of the phosphorescent paint, can be protected from moisture on the floor by having the above-described coating layer.

  As described above, according to the present invention, it is possible to provide a laying material with a guide sign that can be installed at a low cost and does not have a problem such as a failure or a reduction in the display function of the guide sign.

  Next, an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a view showing a laying material with a guide sign according to an embodiment of the present invention, FIG. 1 (a) is a plan view thereof, and FIG. 1 (b) is a longitudinal sectional view thereof.

  A laying material 10 with a guide sign according to the present embodiment (hereinafter referred to as “laying material 10”) includes a transparent base 11 made of a plate-like highly transmissive glass, and a colored layer 13 formed on the back surface 11b of the transparent base 11. The guide sign 12 indicating the direction in which the emergency exit and exit are located is drawn using the colored layer 13. And the character and the pattern of the guidance sign 12 drawn on the back surface 11b side can be visually recognized from the surface 11a side of the transparent base | substrate 11. FIG. FIG. 1A shows a state in which the guide sign 12 drawn on the back surface 11 b side of the transparent substrate 11 is viewed from the front surface 11 a side of the transparent substrate 11.

  As the highly transmissive glass forming the transparent substrate 11, for example, “Claritya”, trade name of Asahi Glass Co., Ltd. can be used. According to Asahi Glass Co., Ltd.'s 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 plate thickness of 8 mm. When the plate thickness is 12 mm, the ultraviolet transmittance is 43.5% and the visible light transmittance is 85.7%. However, in the case of the highly transparent glass “Claritya”, the plate thickness is 8 mm and the ultraviolet transmittance is 74. The visible light transmittance is 91.8%, and the ultraviolet light transmittance is 70.1% and the visible light transmittance is 91.8% when the plate thickness is 12 mm. As described above, the high transmittance glass is remarkably higher than the ultraviolet and visible light transmittance of ordinary glass. Even when the thickness is 12 mm, the ultraviolet transmittance is 70% or more and the visible light transmittance is 90% or more.

  The laying material 10 is installed on, for example, a subway station yard or an underground shopping center floor. Therefore, it is preferable that the transparent substrate 11 has such a strength that it will not be damaged even if it is stepped on by a passerby on a daily basis. The above high-permeability glass can be used on the floor without any problem in terms of strength because it can obtain mechanical properties equivalent to the hardness and strength of general float glass.

  Among the guidance signs 12 in the present embodiment, a symbol indicating an evacuation exit, a symbol indicating an evacuation direction, and a character indicating an evacuation exit, which are drawn in black in FIG. The part is drawn with green general paint. Further, the background portion of the back surface 11b of the transparent substrate 11 excluding the symbol portion indicating the evacuation port and the symbol indicating the evacuation direction and the characters indicating the evacuation port are light yellow. A paint having a green luminous property is applied. The colored layer 13 is formed of such a general green paint and a light yellow-green phosphorescent paint.

For example, the product name “Luminova” (product number: N night light BG-300) manufactured by Nemoto Special Chemical Co., Ltd. can be used for the phosphorescent paint portion of the colored layer 13. However, according to the Fire and Disaster Management Agency Notification Revision (Revised March 29, 2006), which stipulates the standards for phosphorescent guidance signs to be installed in hallways or passages, JISZ8716 fluorescent lamps irradiate external light with an illuminance of 200 lux for 20 minutes. After that, after 20 minutes, the display surface needs to have an average luminance of 24 millicandela / m ² or more and less than 100 millicandela / m ² . For this reason, the laying material 10 of the present invention uses a phosphorescent paint capable of satisfying the standard of the phosphorescent guidance sign.

  Further, the colored layer 13 made of a general paint and a phosphorescent paint applied on the back surface 11 b of the transparent substrate 11 is covered with a coating layer 14 that prevents liquid and air from passing through the colored layer 13. The covering layer 14 may be formed of a metal oxide glass or a stainless plate, for example. By performing glass coating treatment or adhesion of a stainless steel plate on the colored layer 13, glass or stainless steel does not transmit moisture or air, so that it is possible to protect the phosphorescent paint having poor water resistance from moisture. As the glass coating agent, for example, a heatless glass system (registered trademark) manufactured by Cosmo Technology Co., Ltd., which can perform a coating process at room temperature, can be used.

  FIG. 2 is a view for explaining an example in which the laying material 10 of the present embodiment is installed on the floor surface.

  The laying material 10 of this embodiment is used for floor surfaces of tunnel escape passages, subway stations, underground malls, and the like. The installation example shown in the figure is a case where the present invention is applied to a current internally-illuminated guide light embedded in a floor surface. As shown in FIG. 2, a recessed box 21 is embedded in an embedding hole provided in the floor surface 20. A support piece 23 for supporting the frame 22 is provided at the upper end of the box body 21, and a screw hole for screwing the frame 22 is formed in the support piece 23. The box 21 contains a fluorescent lamp 24, an electric wire (not shown) for lighting the fluorescent lamp 24, a storage battery 25 for lighting the fluorescent lamp 24 in the event of a power failure, and a display above the fluorescent lamp 24. A packing 27 for mounting the plate 26 is fitted therein. The display board 26 is obtained by printing an emergency exit pattern or an arrow on an acrylic resin transparent board. The display plate 26 and the protective glass 28 are placed on the packing 27 in this order. The packing 29 is fitted into the protective glass 28, and the frame 22 is placed on the packing 29 so that the ribs 29 a of the packing 29 come out from the inside of the frame 22. The frame 22 is attached to the support piece 23 with screws 30. As described above, the current internally guided light is embedded in the floor.

  When the laying material 10 of the present invention is applied to such a floor-embedded guide light, the laying material 10 is produced in a shape that can be set between the packings 27 and 29 shown in FIG. It is only necessary to remove both of the glasses 28 and change to the produced laying material 10. In this case, components such as the fluorescent lamp 10 and the storage battery 26 housed in the box 22 are unnecessary and are removed. Furthermore, the space in the box body 22 from which all parts have been removed may be filled with mortar. Thus, the laying material 10 of the present invention can be easily applied to the existing floor-embedded guide light. Therefore, there is almost no construction cost for the laying material 10 on the floor surface on which the floor-embedded guide light already exists.

  Of course, in addition to the above installation examples, the laying material 10 may be fixed to the floor surface with cement, an adhesive, a double-sided tape, or the like. When it is desired to prevent the laying material 10 from protruding above the floor surface, a recess having the same dimensions as the length and width of the laying material 10 is formed on the floor surface, and the laying material 10 is placed in the recess. Install it so that it fits in. Moreover, the laying material 10 of this invention can be used not only for a floor surface. For example, the present invention may be applied to a wall-embedded guide lamp.

  FIG. 3 is a diagram illustrating another example of the guidance sign drawn on the laying material according to the present embodiment. The guide sign 12 that can be drawn on the laying material 10 according to the present embodiment is one shown in FIG. 1 or a one-way guide direction as shown in FIG. Some of them only display arrows. Of course, the guidance sign that can be drawn on the laying material 10 is not limited to that shown in FIGS. 1 and 3, and can be appropriately changed according to the place where the laying material 10 is installed.

  Next, the operation and effect of the laying material 10 of this embodiment will be described.

  When the lighting is on in a subway station yard, underground mall, or the like, it is possible for a passer-by to visually recognize the design and characters of the guide sign 12 drawn in green on the back surface of the transparent substrate 11. On the other hand, when a power outage occurs in a subway station, an underground shopping center, etc., and the passage becomes dark, the area where the phosphorescent paint is applied on the back surface of the transparent substrate 11 (the symbol indicating that it is an evacuation exit) The background and the background portion excluding the symbol indicating the direction of evacuation and the character indicating the evacuation exit are phosphorescent. As a result, there is a difference in brightness between the symbol indicating the evacuation exit, the symbol indicating the evacuation direction, and the character portion indicating the evacuation exit and the other portions, and the refugee is in the dark. In particular, the guide sign 12 can be easily visually recognized.

  In addition, since the transparent substrate 11 on which the guide sign 12 is drawn is not ordinary glass called blue plate glass but high transmittance glass, the color tone of the guide sign 12 drawn on the back surface of the glass is viewed from the front side of the glass plate. Is hard to change. In other words, when letters and pictures of guide signs are printed in a predetermined color tone on the back side of ordinary glass with a bluish tint, it looks dull and the tone of the guide sign 12 drawn on the back side of the glass changes. End up. Since the color of the guide sign 12 is determined by JIS (Japanese Industrial Standard), when the guide sign 12 visually recognized from the glass surface side is drawn on the back surface of the normal glass, it is difficult to adjust the color tone. On the other hand, in the present invention, since highly transparent glass having no color is used, the color reproducibility of the guide sign 12 through the glass is very high as compared with ordinary glass, and the above-described problems hardly occur. .

  In addition, by installing the laying material 10 on the floor surface, when a fire breaks out and a power failure occurs, even if smoke generated by the fire spreads above the passage, evacuees can easily use the floor guide sign 12 Can be found in. Furthermore, since the evacuees can evacuate while looking at the guide sign 12 in a bent state so as not to smoke the smoke generated by the fire, the laying material 10 of the present embodiment can improve safety in disaster prevention.

  Furthermore, since the guide sign 12 is drawn on the back surface 11b side of the laying material 10 of the present embodiment, the guide sign 12 is worn out even if a passerby steps on the laying material 10 repeatedly when installed on the floor surface. Absent. Therefore, even if the laying material 10 of this embodiment is installed on a floor surface and used for a long period of time, the display function of the guidance sign 12 is not impaired, so it is not necessary to replace it frequently. Moreover, since the laying material 10 of this embodiment is phosphorescent by the phosphorescent paint applied to the back surface 11b, the luminaire that illuminates from the back side of the laying material 10 and the wire piping thereof are installed on the floor. There is no need to bury it in the plane. Therefore, the installation cost and space of the laying material 10 can be significantly reduced.

Moreover, as described above, the high transmittance glass on which the guide sign 12 is drawn using the general paint and the phosphorescent paint on the back surface has a transmittance of 70% or more necessary for the phosphorescence of the phosphorescent material and has the same thickness. The UV transmittance is very high compared to ordinary glass with about 50%. For this reason, phosphorescence of the phosphorescent paint applied to the back surface of the high transmission glass can be performed 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. Because of this light transmission performance, even if it is installed in a dim place where the brightness is reduced to save power, the phosphorescent paint absorbs UV light efficiently and provides sufficient brightness in the event of a power failure. Can be generated. In addition, the Fire Service Agency Notification Revision (revision on March 29, 2006) that stipulates the standards for phosphorescent guidance signs provided in hallways or passages is a special case, and illuminates 100-lux external light for 20 minutes with a fluorescent lamp of JISZ8716. Then, if the display surface after 20 minutes has an average luminance of 150 millicandelas / m ² or more, a phosphorescent guidance sign can be installed. Therefore, the laying material 10 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.

(Other embodiments)
In the embodiment described above, the symbol part indicating the evacuation exit and the direction and the character part indicating the evacuation exit in the guidance sign 12 are drawn with the green general paint, An example is shown in which the background portion excluding the direction symbol and the character indicating the escape port is colored with a light yellow-green phosphorescent paint. However, not only this color scheme but also the ground portion of the symbol indicating the evacuation exit, the symbol indicating the direction and the character portion indicating the evacuation exit of the guide sign 12 are drawn with a phosphorescent paint. And a background portion excluding a symbol indicating a direction and a character indicating that it is an evacuation exit may be painted with a green general paint. That is, in the laying material 10 of the embodiment shown in FIG. 1, the color of the guidance sign provided in the passage or hallway defined by the Fire Department is taken, but the color required for the guidance sign provided in the evacuation exit is taken. Is also possible.
