Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is arranged in a room where a fire extinguishing facility such as a sprinkler is provided, so that in the case of a fire from a stored article, the water discharged from the fire extinguishing facility can be effectively flowed down to assist the fire extinguishing. It is about fire extinguishing support shelf that we can do.
[0002]
[Prior art]
When installing bookshelves and article storage shelves indoors, the ease of fire extinguishing when a fire breaks out from the stored articles should be considered, but in the past it has not been considered much. In particular, mobile shelves are often in a state where the shelves are converged, so if there is a fire from the stored items inside or a fire from the periphery of the mobile shelf, the water is discharged from a fire extinguishing facility such as a sprinkler. However, it is difficult for water to reach the fire. Some electric moving shelves are stopped with a gap between the shelves. In such an electric moving shelf, water can pass through the gap. However, since the gap is not originally formed in consideration of fire extinguishing, no effort has been made to efficiently introduce water into the gap, and the fire source is an article in the shelf or an article around the moving shelf. In some cases, it is difficult for water to reach fire source items.
[0003]
In addition, there is an idea that the ceiling of the shelf is greatly opened and water is allowed to flow into the shelf, but due to the structure of the shelf, there is a limit to the open area of the ceiling, so that it can be released from fire extinguishing equipment such as sprinklers. The ratio of the amount of water on the shelf to the amount of water is small, and the fire extinguishing efficiency is poor. Further, if the ceiling of the shelf is greatly opened, there is a problem that dust is easily applied to the stored articles.
[0004]
The above situation can be said to be about goods shelves with a height dimension of 3 m or less in the Fire Service Act. In the case of goods shelves with a height dimension of 3 m or more, a shielding plate is attached to the upper part of the shelf. It is structured to install a sprinkler. However, with such a structure, there is a drawback that the cost increases and the product becomes expensive.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of a fire extinguishing support shelf according to the present invention will be described with reference to the drawings.
In FIG. 1, a plurality of moving shelves 10 are arranged on a floor 40 that defines the lower limit of the indoor space so as to be able to converge with each other and to be able to form a work path for taking in and out articles between arbitrary shelves. ing. Each movable shelf 10 can be moved in a direction corresponding to the left and right operation switches 20 and 22 by selecting and operating one of the operation switches 20 and 22 provided on the left and right sides of the side panel 18. It is a shelf. There are various types of movement of the electric movable shelf, but the present invention can be applied to any type of movement. Moreover, the movable shelf to which the present invention is applied is not limited to an electric movable shelf. It may be a manual moving shelf. Each moving shelf 10 may move along a rail laid on the floor 40 or may be railless.
[0013]
Above each movable shelf 10, sprinklers 44 as fire extinguishing equipment are arranged at appropriate intervals on a ceiling surface 42 that defines the upper limit of the indoor space. As is well known, the sprinkler 44 is connected to a sensor for detecting smoke and heat. When this sensor is operated, water as a fire extinguisher is discharged from the nozzles in all directions, and water is applied to each movable shelf 10 from above. It is like that. The fire extinguisher is not limited to water, but may be a gas or powder or a liquid fire extinguisher other than water, and these fire extinguishing agents are discharged from the fire extinguishing equipment corresponding to each property. Is done.
[0014]
As shown in FIGS. 1 to 4, each movable shelf 10 has a plurality of support columns 12 that form a main skeleton thereof. A plurality of support columns 12 are arranged side by side in the front direction and three in the depth direction. The lower ends of the support columns 12 are erected on a frame (not shown) and connected to the frame integrally. The upper ends of the support columns 12 are The top plate 24 is connected. The support 12, the above frame, and the top plate 24 constitute a skeleton of the movable shelf 10. Each of the movable shelves 10 is a duplex shelf having article storage portions arranged back to back and having article access ports on both sides, and a shelf board 16 is interposed between one article storage section and the other article storage section with sleeve plates 14 interposed therebetween. It is attached to the original.
[0015]
The sleeve plate 14 has hooks at both ends in the width direction, and the hooks are hooked into holes formed at regular intervals in the vertical direction on the two columns 12 arranged in the depth direction of the movable shelf 10. It is suspended over the column 12 of the book. Similarly, hooks of other sleeve plates 14 are hooked on two struts 12 that are adjacent in the frontage direction and arranged in the depth direction. The pair of sleeve plates 14 latched in this manner has a lower end edge bent at a right angle to form a receiving portion of the shelf plate 16, and both end portions of the shelf plate 16 between the receiving portions of the pair of sleeve plates 14. Is received and the shelf board 16 is attached. Hereinafter, the space divided by the columns 12 adjacent in the frontage direction is referred to as “ream”. The shelf according to the illustrated embodiment has two shelf boards 16 attached in the frontage direction. Such shelves are “double” shelves.
A gap 32 corresponding to the width of the support column 12 is generated between the shelf boards 16 arranged in the depth direction.
[0016]
In the case of a conventional general shelf, the top plate 24 covers the entire upper end of the shelf. However, in the shelf according to the present invention, an opening is formed at the upper end of the shelf. In the illustrated embodiment, as shown in FIG. 2 and FIG. 3, an opening 28 is formed in the back as viewed from the outlet for the article. Since the illustrated embodiment is a duplex shelf, an opening 28 is formed between one article storage section and the other article storage section that are back to back. The opening 28 is formed over substantially the entire opening direction of the “ream”. The opening 28 may be formed in the shape of a window hole in one top plate 24 or may be formed by attaching two top plates 24 with an interval corresponding to the width of the opening 28.
[0017]
The upper end of each shelf is also provided with an inclined surface 26 that decreases from the front side toward the back as viewed from the entry / exit port. The inclined surface 26 is formed by attaching two inclined plates on the top plate 24. The inclined surface 26 is for collecting water discharged from the sprinkler 44 from the inlet / outlet side of the article toward the back, and the collected water is guided to the opening 28 so that the rear end of the inclined surface 26 is collected. The edge (lower edge) is in contact with the edge of the opening 28. With respect to the shelf plate 16 attached below the top plate 24, the width between the shelf plate 16 on the one article storage unit side and the shelf plate 16 on the other article storage unit side is almost the same as the opening 28. The gap 48 (see FIG. 5) is formed. This gap 48 is in spatial communication with the opening 28.
[0018]
The operation or effect of the embodiment of the present invention configured as described above will be described below. When a fire occurs, as shown in FIG. 1, the sprinkler 44 detects smoke or heat and discharges water from above the moving shelf 10 in four directions. Each movable shelf 10 covers the discharged water, and the water covered by each movable shelf 10 flows along the inclined surface 26 from the front side to the back side as viewed from the entrance of the article and is collected in the opening 28. The collected water flows down from the opening 28, and further, the gap 48 formed between the two article storage portions of the duplex shelf flows down in a curtain shape as shown in FIGS. This water curtain has the effect of lowering the temperature of the article storage section, and can prevent the fire from spreading to the stored articles.
[0019]
Also, if the fire source is a shelf storage item, it has the effect of preventing the spread of fire as described above, and in addition, even if some of the flowing water scatters and extinguishes the fire source or does not extinguish Can weaken the fire.
When the stored article is a book, it is common to store the back cover toward the front, that is, the outside of the shelf, and the opposite side of the back cover, that is, the open side toward the back. Books are less likely to burn on the back cover side and more open on the open side than the back cover side. According to the above-described embodiment, water concentrates and flows down in the form of a curtain on the open side of books that are relatively flammable, so that the stored books have a high fire prevention or extinguishing effect.
[0020]
Even in the state where the movable shelves 10 are converged, in the illustrated embodiment, as shown in FIGS. 2, 3, and 5, the movable shelves 10 are connected to each other, in other words, the front of the article storage space of the movable shelf 10. A gap 30 is formed in the gap. Therefore, the water discharged from the sprinkler 44 also enters the gap 30 and flows down to the gap 30, in other words, the front of the article storage space of the movable shelf 10. By blocking intrusion and advancement, it is possible to prevent the spread of fire to the stored item, or to extinguish the fire of the stored item that is the source of fire or to suppress the fire power.
In order to increase the amount of water flowing down the front surface of the article storage space as much as possible, the front surface side of the article storage space of the inclined surface 26 is an inclined surface opposite to the inclined surface 26 as indicated by reference numeral 50 in FIG. In addition, a part of the water covered by the movable shelf 10 may flow down to the front side of the article storage space.
[0021]
Further, since there is the gap 32 corresponding to the width of the support column 12 between the stations as shown in FIGS. 2, 4, and 5, the water discharged from the sprinkler 44 is also in the gap 32. Enters and flows down. Since the article storage space is surrounded by the water flowing down in this way, the fire prevention effect or the fire extinguishing effect can be further enhanced.
[0022]
According to the illustrated embodiment, an opening 28 through which water can flow down is formed between the article storage spaces arranged in a back-to-back state at the upper end of the duplex shelf, and a gap 48 leading to the opening 28 is formed. Therefore, when the stored item becomes a fire source, or when the periphery of the movable shelf 10 becomes a fire source, the gap 48 and the opening 28 act like a chimney, and smoke and hot air Quickly rises through the gap 48 and the opening 28, and quickly reaches the sprinkler 44 of the ceiling surface 42 shown in FIG. Therefore, there is an advantage that the occurrence of a fire is detected early and the fire can be extinguished at an early stage.
[0023]
As mentioned above, although the effect was demonstrated about the case where water is used as a fire extinguisher, the same effect can be obtained also when a gaseous or powder thing, or a liquid thing other than water is used as a fire extinguisher. it can.
[0024]
Next, another embodiment of the fire extinguishing support shelf according to the present invention will be described with reference to FIGS. One of the differences between this embodiment and the above embodiment is that a cover 34 that allows intrusion of a fire extinguishing agent such as water and prevents intrusion of dust is attached to the opening 28. The cover 34 is approximately the same length as the opening 28 and covers the opening 28. Both ends in the length direction of the cover 34 are bent downward, and the bent portions are attached to the top plate of the movable shelf 10, thereby forming slit-like gaps on both sides in the length direction of the cover 34, A fire extinguishing agent enters the opening 28 from this gap. Further, since the cover 34 is attached, dust can be prevented from directly entering the opening 28.
[0025]
Another difference between the above embodiment and the above embodiment is that a back panel 52 is attached to a gap 48 formed between one article storage space and the other article storage space. 52, the gap 48 is divided into a gap 48 on one article storage space side and a gap 48 on the other article storage space side. The rear panel 52 is disposed on the back of the article storage space when viewed from both article storage spaces.
[0026]
The back panel 52 is made of a panel having at least heat insulation. Examples of the panel having heat insulation include a gypsum panel, a zeolite panel, and a diatomaceous earth panel. In particular, diatomaceous earth-based panels are composed mainly of diatomaceous earth covered with countless fine holes made of siliceous material, and exhibit excellent heat insulation, fire resistance, humidity control function, and deodorizing effect. Moreover, as shown in FIG. 10, the back panel 52 which consists of a diatomaceous earth system panel in which the cross-sectional V-shaped groove | channel covering the whole vertical direction was formed in the both surfaces on both surfaces was used. The back panel 52 is attached over substantially the entire height and width of the movable shelf 10.
[0027]
According to the embodiment in which the back panel 52 is attached as described above, since the back panel 52 has heat insulation properties, when a fire occurs in the vicinity of the stored item or the moving shelf, the one item storage space and the other Propagation of radiant heat between the article storage spaces is prevented, and the effect of preventing the spread of fire between the article storage spaces is enhanced. Further, water discharged from the sprinkler 44 and flowing in from the opening 28 or other digestive agent flows down along the back panel 52. Therefore, the temperature rise of the back panel 52 is suppressed and the fire spread preventing effect is further enhanced.
[0028]
Furthermore, the groove | channel formed in both surfaces of the back panel 52 plays the role of the guide groove | channel of the digestive agent which flows down, and can make a digestive agent flow down rapidly effectively. Thereby, a digestive agent can be rapidly guide | induced to a fire source and a fire prevention effect and a fire extinguishing effect can be heightened. In particular, in stacked shelves that build another shelf group on the shelf group, it is required that the digestive agent released when the occurrence of a fire is detected quickly reaches the lower shelf group, As in the above-described embodiment, in the shelf having the back panel 52 in which the vertical grooves are formed on both sides, the digestive agent quickly reaches the lower shelf group and enhances the fire prevention effect or the fire extinguishing effect of the stacked shelf. be able to.
[0029]
When the back panel 52 is composed of the diatomaceous earth panel, in a normal use state, due to its humidity control function, when the humidity is high, countless fine holes absorb the moisture and lower the humidity in the shelf from the surroundings. When the humidity is low, exhale the absorbed moisture and raise the humidity in the shelf higher than the surrounding area. In this way, the humidity fluctuation in the shelf can be suppressed, and the stored articles can be maintained in an appropriate humidity environment.
Moreover, since the surface of a diatomaceous earth system panel is comparatively smooth, if the back panel is comprised with a diatomaceous earth system panel, there also exists an advantage which can discharge | release the discharged water smoothly.
[0030]
In the embodiment described above, the shelf is movable. However, the shelf type to which the technical idea according to the present invention can be applied is not limited to the movable shelf. The technical scope of the present invention extends to a fixed shelf to which the technical idea according to the present invention is applied.
The inclined surface 26 may be formed of an inclination angle control plate capable of changing the inclination angle so that the momentum of the digestive agent flowing along the inclined surface 26 can be controlled.
The present invention can be applied to a single shelf, that is, a single shelf having an article storage portion on one side, whether it is a movable shelf or a fixed shelf.
[0031]
【The invention's effect】
According to invention of Claim 1, it is a fire extinguishing support shelf arrange | positioned in the room | chamber interior provided with the fire extinguishing equipment, Comprising: From the front side to the upper part of the shelf which has an articles | goods storage part, from the front side seeing from the outlet of goods An opening that allows a fire extinguisher to flow down in a curtain shape along the gap formed at the back of the article storage unit is provided at the upper end of the shelf from the entrance of the article. Since the lower edge of the inclined surface is in contact with the edge of the opening, the digestive agent released in the event of a fire opens along the inclined surface. And flow down from the opening to suppress the temperature rise of the article storage space to prevent the spread of fire and to exhibit a fire prevention effect or a fire extinguishing effect.
[0032]
According to the invention described in claim 4, in the invention described in claim 1, since the shelf has the back panel on the back of the article storage unit, the back panel suppresses the propagation of radiant heat, and the fire prevention effect or fire extinguishing. The effect can be further enhanced.
