Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is arranged in a room provided with a fire extinguishing facility such as a sprinkler, so that, when a fire occurs in a stored article, water discharged from the fire extinguishing facility can be effectively flowed down. The present invention relates to a fire extinguishing support shelf that can help extinguish a fire.

[0002]

2. Description of the Related Art When a bookcase or an article storage rack is installed in a room, it should be taken into consideration how easy it is to extinguish a fire when a stored article fires, but it has not been taken into consideration so far. In particular, in the case of mobile shelves, the shelves are often in a bundled state, so if a fire occurs from the stored items inside or around the mobile shelves, water is discharged from a fire extinguisher such as a sprinkler. Water is hard to reach the fire. Some electric mobile shelves have a gap between them to be stopped, and in such an electric mobile rack, water can pass through the gap. But,
Since the above-mentioned gap is not originally formed in consideration of fire extinguishing, no measures have been taken to efficiently guide water into the gap, and when the origin of the fire is an article inside the shelf or an article around the moving shelf. Has the drawback that it is difficult for water to reach the source of the fire.

There is also an idea to open the ceiling of the shelf to a large extent to allow water to flow into the shelf, but the open area of the ceiling is limited due to the structure of the shelf, and fire extinguishing equipment such as sprinklers. The ratio of the amount of water on the shelves to the amount of water discharged from is small, and fire extinguishing efficiency is poor. Further, if the ceiling of the shelf is wide open, there is also a problem that the stored articles are easily dusted.

According to the Fire Service Law, the above situation can be said for an article shelf having a height of 3 m or less. In the case of an article shelf having a height of 3 m or more, a shield plate is attached to the upper part of the shelf. A sprinkler is installed in that part. However, this structure increases cost,
It has the drawback of becoming an expensive product.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a fire extinguishing support shelf according to the present invention will be described below with reference to the drawings. In FIG. 1, a plurality of movable shelves 10 are arranged on a floor 40 that defines the lower limit of the indoor space so that they can be bundled with each other and that a work passage for loading and unloading articles can be formed between arbitrary shelves. ing. Each movable rack 10 can be moved in a direction corresponding to the left and right operation switches 20 and 22 by selectively operating one of the operation switches 20 and 22 provided on the left and right of the side panel 18. It's a shelf.
Although there are various types of movement of the electric mobile rack, the present invention can be applied to any movement type. The mobile shelf to which the present invention is applied is not limited to the electric mobile shelf. It may be a manual mobile rack. Each movable rack 10 may move along a rail laid on the floor 40, or may be railless.

Above the movable shelves 10, sprinklers 44 as fire extinguishing equipment are arranged at appropriate intervals on the ceiling surface 42 defining the upper limit of the indoor space. As is well known, the sprinkler 44 is connected to a sensor that detects smoke or heat, and when this sensor operates, water is discharged from the nozzle in all directions as extinguishant, and water is sprayed from above onto each movable rack 10. It is like this. The fire extinguishing agent is not limited to water, but may be a gas or powdery extinguishing agent in the form of a liquid or a liquid other than water.These extinguishing agents are released from the extinguishing equipment according to their respective properties. To be done.

As shown in FIGS. 1 to 4, each movable rack 1
0 has a plurality of struts 12 forming its main skeleton.
The plurality of columns 12 are arranged side by side in the front direction and three in the depth direction. The lower ends of the columns 12 are erected on an unillustrated underframe and integrally connected to the underframe. They are connected by a top plate 24. The support column 12, the underframe, and the top plate 24 form a skeleton of the movable shelf 10. Each of the movable shelves 10 is a double-type shelf in which the article storage sections are arranged back to back and the article inlet / outlet ports are provided on both sides, and the shelf boards 16 of the one article storage section and the other article storage section interpose the sleeve plate 14 therebetween. It is attached to the original.

The sleeve plate 14 has hooks at both ends in the width direction, and the two columns 12 arranged in the depth direction of the movable shelf 10.
The hooks are hooked in the holes formed at regular intervals in the vertical direction, so that they are hooked over the two columns 12. Similarly, another sleeve plate 14 is formed on the two columns 12 that are adjacent to each other in the frontage direction and lined up in the depth direction.
The hook is locked. The lower end edges of the pair of sleeve plates 14 thus hooked are bent at right angles to form a receiving portion for the shelf plate 16.
Both ends of the shelf 16 are received between the receiving portions of the shelf 16
Is attached. Hereinafter, the space partitioned by the columns 12 adjacent to each other in the frontage direction is referred to as "ream". In the shelf according to the illustrated embodiment, two shelf boards 16 are attached in the frontage direction. Such a shelf is a "double" shelf.
A gap 32 corresponding to the width of the column 12 is formed between the shelf plates 16 arranged in the depth direction.

In the case of a conventional general shelf, the top plate 24 covers the entire upper end of the shelf, but 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 FIGS. 2 and 3, an opening 28 is formed in the back when viewed from the article inlet / outlet port. Since the illustrated embodiment is a double 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 frontal direction of the "ream". The opening 28 is one top plate 2.
4 may be formed in the shape of a window hole, or may be formed by attaching two top plates 24 at intervals corresponding to the width of the opening 28.

The upper end of each shelf is also provided with an inclined surface 26 which is lowered from the front side toward the back side when viewed from the entrance / exit of articles. The inclined surface 26 is formed by attaching two inclined plates on the top plate 24. The inclined surface 26 is for collecting the 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. The edge (lower edge) is in contact with the edge of the opening 28. As for the shelf board 16 attached below the top board 24, one of the shelf boards 16 on the side of the article storage section,
The opening 28 is formed between the other shelf 16 on the article storage side.
A gap 48 (see FIG. 5) having a width substantially the same as that of is formed. The gap 48 spatially communicates with the opening 28.

The operation or effect of the embodiment of the present invention thus configured will be described below. When a fire occurs, as shown in FIG. 1, the sprinkler 44 detects smoke, heat, or the like, and discharges water from above the moving shelf 10 in all directions. Each mobile rack 10 covers the discharged water, and each mobile rack 1
The water covered with 0 flows along the inclined surface 26 from the front side to the back side as viewed from the entrance / exit of the article, and is collected in the opening 28. The collected water flows down from the opening 28, and further flows down like a curtain as shown in FIGS. 3 to 5 into the gap 48 formed between both the article storage portions of the double shelf. This water curtain has the effect of lowering the temperature of the article storage section, and can prevent the articles contained in the curtain from spreading.

Further, even when the origin of the fire is an article stored in a shelf, it has the effect of preventing the spread of fire as described above, and in addition, a part of the flowing water is scattered to extinguish the origin of the fire or to extinguish the fire. If you don't, you can weaken the fire. When the articles to be stored are books, it is usual to store them with the spine cover facing toward the front, that is, the outside of the shelf, and the opposite side of the spine cover facing toward the back. Books are hard to burn on the spine side,
The open side burns more easily than the spine side. According to the above-mentioned embodiment, since water is concentrated and flows down like a curtain on the opening side of the books which are relatively inflammable, the stored books have a high fire prevention or extinguishing effect.

Even if the movable shelves 10 are in a bundled state, in the illustrated embodiment, as shown in FIGS. 2, 3 and 5, the movable shelves 10 are mutually stored, in other words, the articles are stored in the movable shelves 10. A gap 30 is formed on the front surface of the space. Therefore, the water discharged from the sprinkler 44 also enters the gap 30 and flows down the gap 30, in other words, the front surface of the article storage space of the movable shelf 10 to remove smoke and heat from the front surface of the article storage space. It is possible to prevent invasion and advancement, prevent the spread of the fire on the stored article, or suppress the fire or the fire of the stored article that has caused the fire. 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. Alternatively, part of the water covered by the movable shelf 10 may be allowed to flow down to the front side of the article storage space.

Furthermore, between the stations, as shown in FIGS.
As shown in FIG. 5, the gap 3 corresponding to the width of the column 12 is formed.
Since there are two, the water discharged from the sprinkler 44 enters the gap 32 and flows down. In this way, since the article storage space is surrounded by water flowing down on all four sides, the fire prevention effect or fire extinguishing effect can be further enhanced.

According to the illustrated embodiment, an opening 28 through which water can flow down is formed between the article storage spaces arranged back to back at the upper end of the double shelf, and the opening 28 is formed in the opening 28. Since there is a gap 48 that communicates, when the stored article becomes the source of fire or the moving shelf 10
When the surrounding area becomes a fire source, the gap 48 and the opening 28 act as if they were a chimney, and smoke and hot air are generated in the gap 4
8 and through the opening 28 to quickly reach the sprinkler 44 on the ceiling surface 42 shown in FIG. Therefore, there is also an advantage that a fire can be detected early and the fire can be extinguished at an early stage.

Although the action and effect have been described above with respect to the case where water is used as the extinguishing agent, the same action and effect can be obtained when a gas or powdery extinguishing agent or a liquid other than water is used. Obtainable.

Next, another embodiment of the fire extinguishing support shelf according to the present invention will be described with reference to FIGS. 6 to 10. One of the differences of this embodiment from the above-mentioned embodiment is that a cover 34 is attached to the opening 28 to allow the extinguishing agent such as water to enter and prevent the ingress of dust. The cover 34 has almost the same length as the opening 28,
It covers above 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 to thereby cover the cover 34.
Slit-shaped gaps are formed on both sides in the length direction of the fire extinguishing agent, and the fire extinguishing agent enters the openings 28 through the gaps. Further, since the cover 34 is attached, dust is prevented from directly entering the opening 28.

Another difference of the above embodiment from 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. In the rear panel 52, there is a gap 48 on the side of one article storage space and a gap 48 on the side of the other article storage space.
It has been divided into two. The back panel 52 is arranged at the back of the article storage space when viewed from both article storage spaces.

The back panel 52 is a panel having at least a heat insulating property. Examples of the heat insulating panel include a gypsum panel, a zeolite panel, and a diatomaceous earth panel. In particular, diatomaceous earth-based panels are mainly composed of diatomaceous earth, which is silicic and covered with innumerable fine pores, and exhibits excellent heat insulation, fire resistance, humidity control function, and deodorizing effect. Further, as shown in FIG. 10, a back panel 52 made of a diatomaceous earth panel was used, in which grooves having a V-shaped cross section were formed at regular intervals on both sides in the vertical direction. The back panel 52 is attached over almost the entire height and width of the movable shelf 10.

According to the embodiment in which the back panel 52 is attached as described above, since the back panel 52 has a heat insulating property, when a fire occurs in the vicinity of the stored articles or the moving shelves, one of the article storages is stored. Radiation heat is prevented from propagating between the space and the other article storage space, and the effect of preventing fire spread between the article storage spaces is increased. Further, water discharged from the sprinkler 44 and flowing in from the opening 28,
Alternatively, the other extinguishing agent flows down along the rear panel 52. Therefore, the temperature rise of the back panel 52 is suppressed, and the spread of fire prevention effect is further enhanced.

Further, the grooves formed on both sides of the back panel 52 serve as guide grooves for the extinguishing agent to flow down, so that the extinguishing agent can be effectively and quickly flowed down.
With this, you can quickly guide the extinguishant to the fire,
The fireproof effect and fire extinguishing effect can be enhanced. In particular, in the case of a stacking type shelf in which another shelf group is constructed on the shelf group, it is required that the extinguishant released when a fire is detected reaches the lower shelf group quickly. In a shelf having a back panel 52 having vertical grooves formed on both sides as in the above-described embodiment, the extinguishant quickly reaches the lower shelves to enhance the fireproofing or extinguishing effect of the stacked shelves. be able to.

When the rear panel 52 is made of the diatomaceous earth panel, in normal use, due to its humidity control function, when the humidity is high, a myriad of fine holes absorb the moisture and the humidity in the shelf is kept around. When the humidity is low, the absorbed humidity is discharged and the humidity in the shelf is raised above the surroundings.
In this way, it is possible to suppress humidity fluctuations in the shelves and maintain the stored articles in a moderate humidity environment. In addition, since the surface of the diatomaceous earth panel is relatively smooth, if the rear panel is made of a diatomaceous earth panel, there is also an advantage that the discharged water can smoothly flow down.

In the embodiment described above, the rack is movable, but the form of the rack to which the technical idea of the present invention can be applied is not limited to the movable rack. The technical scope of the present invention extends to fixed shelves to which the technical idea of the present invention is applied. The inclined surface 26 may be formed of an inclination angle control plate whose inclination angle can be changed so that the momentum of the extinguishing agent flowing along the inclined surface 26 can be controlled. The present invention is applicable not only to a movable shelf or a fixed shelf, but also to a single shelf, that is, a single shelf having an article storage portion on one surface.

[0031]

According to the invention described in claim 1, the upper end of the shelf is provided with an inclined surface which decreases from the front side toward the back when viewed from the loading / unloading port of the article, and the digestive agent is provided along the back. Since the opening that can be made to flow down is formed, the extinguishing agent released at the time of a fire is collected in the opening along the inclined surface and flows down from the opening to suppress the temperature rise of the article storage space and spread the fire. Prevents and exerts a fire prevention or extinguishing effect.

According to the invention described in claim 4, in the invention described in claim 1, since the shelf has a rear panel on the back of the article storage portion, the rear panel suppresses the propagation of radiant heat and prevents fire. The effect or fire extinguishing effect can be further enhanced. If the back panel is made to have heat insulating properties as in the fifth aspect of the invention, the fireproof effect or the fire extinguishing effect can be further enhanced. If the back panel has a humidity control function as in the sixth aspect of the invention, it is possible to suppress humidity fluctuations in the article storage space and maintain a good article storage environment.
