Description

The present invention relates to a sheet deploying device for disaster prevention equipment that suppresses and extinguishes a fire that has occurred in a large space such as a warehouse.

Conventionally, as a disaster prevention facility that suppresses and extinguishes fires that occur in the monitored area, when a fire detector detects a fire, a fire prevention section is formed by closing a metal fire shutter in conjunction with the fire detection. The fire alarm equipment (Patent Document 1) that suppresses the spread of fire and the sprinkler fire extinguishing equipment (Patent Document 2) that suppresses the fire by spraying water for fire extinguishing by opening the sprinkler head in response to the heat flow from the fire. Are known.

A disaster prevention curtain fire extinguishing system for a mechanical parking lot is known (Patent Document 3). This disaster prevention curtain fire extinguishing system has multiple stages of parking stages with parking areas for vehicles in mechanical parking lots, and disaster prevention curtains are provided at the front and both sides of the ceiling of each parking area. When a fire is detected in the area, the disaster prevention curtain descends to close the front and both sides and extinguish the fire by ejecting fire-extinguishing gas from the fire-extinguishing nozzle.

In addition, the conventional disaster prevention curtain is driven by a motor to lower it, and when the fire is extinguished, the motor is driven to wind it up.

JP, 2017-2111780, A JP, 2005-146840, A JP-A-5-154216

However, such a conventional disaster prevention facility has a problem when applied to a facility having a wide space such as a warehouse.

For example, a metal fire-retardant shutter does not have sufficient heat-shielding property, its facility structure is large, and it is not easy to repair it after a fire.

Conventionally, the protective compartment is formed over a relatively large area in accordance with the layout of rooms and floors.However, in large warehouses, etc., the structural features and the interior of the warehouse It is not realistic to form fire compartments finely by using the conventional fire shutters because of the physical characteristics of storing and putting goods in and out of rack shelves and the like.

Also, in the case of a high ceiling like a warehouse, for example, fire extinguishing water from sprinkler fire extinguishing equipment is scattered during the fall and the amount of spray per unit area is reduced, resulting in low watering efficiency, while water is spread over a wide area. There is a problem of increasing loss.

In addition, the conventional disaster prevention curtain fire extinguishing system does not have a problem in the case of a compartment structure in which the compartments to be extinguished are vertically and horizontally partitioned by a pillar structure like the parking part of a mechanical parking lot, but it is a partition structure like a warehouse. It is difficult to apply to a large space without.

In a large space such as a warehouse, even if there is a partition structure, it is necessary to lower the disaster prevention curtain from a height of more than 10 meters to close the target section, and the curtain is lowered by a motor drive. However, there is a problem that it takes time for the curtain to completely descend, the fire spreads during that time, and sufficient fire suppression cannot be expected.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a sheet deploying device for disaster prevention equipment that can surely suppress and extinguish a fire, targeting a facility having a high ceiling such as a warehouse and having a large space area structurally.

(Basic effect)
The present invention relates to a sheet expansion device for disaster prevention equipment that suppresses and extinguishes fires in a protected space, a partition sheet using a cloth-like material having fire resistance, fire resistance, heat resistance, or smoke shielding, and a predetermined protection space. Body means fixed to the position, fixing means for fixing one end of the partition sheet to the body means, holding means for holding the partition sheet in a non-deployed state, and holding of the partition sheet by the holding means in case of fire in the protective space. When the fire occurs in a large protected space such as a warehouse, it is released and the other end is dropped, so that it expands so as to partition any target area including the fire occurrence place in the protected space. By expanding the partition sheet so as to partition the target area including the generation area from the surrounding area, a partition area is formed in the protective space, and flame spread, smoke shield, and heat shield can be expected to prevent fire spread and smoke diffusion. ..

In addition, by spraying fire extinguishing water or fire extinguishing agents such as fire extinguishing foam into the compartments that have been partitioned by expanding the partition sheet, the extinguishing agent that has been sprayed will not spread around, and the spray will be concentrated at the location of the fire. It is possible to suppress the fire reliably and to extinguish the fire, improve the fire extinguishing efficiency, suppress and prevent the diffusion of the extinguishing agent to the surroundings, and minimize water loss and the like.

(Effect of the holding state of the partition sheet)
Further, since the holding means holds the partition sheet in the main body means in a state of being rolled into a roll or in a state of being folded into a bellows, the sheet unfolding device is provided on the ceiling side of a protected space with a large space area such as a warehouse. However, since the partition sheet is normally kept compact, the protective space can be installed in a small space.

Also, at the time of fire, by releasing the holding of one end of the partition sheet that is held in a roll or bellows state, it is possible to reliably drop due to its own weight and securely deploy it up and down. Compared with disaster prevention curtains that are deployed, even when the deployment height of partition sheets exceeds 10 meters like in a warehouse, the deployment speed of the sheets is fast, and it can be deployed in a short time to handle fires, and complicated equipment It can be deployed without the need for or control.

(Effect of the sheet length of the partition sheet)
Also, since the partition sheet has a sheet length that is longer than the installation height of the main body means, in the case of a conventional steel fireproof shutter, if there is an obstacle on the floor, it will not descend to the floor and there will be a gap to extinguish the fire. However, since the partition sheet in a cloth state is flexible, it is possible to suppress the occurrence of gaps by measuring a long length, and to reduce the extent of fire extinguishing, fire spread prevention, etc. Can be suppressed.

(Effect of spraying the sheet coolant)
Further, a cooling agent spraying means for spraying a cooling agent to the partition sheet expanded by the expanding means is provided, and the cooling agent spraying means sprays the cooling agent on one or both sides of the partition sheet expanded by the expanding means. Furthermore, since the cooling agent spraying means sprays cooling water as a cooling agent, by spraying the cooling water onto the partition sheet by the spraying means to wet the partition sheet, the partition sheet has flame-retardant property, smoke-shielding property, and heat-shielding property. It can be further increased. Further, since the cooling water spraying means sprays the cooling water on one side or both sides of the partition sheet as needed, for example, fire extinguishing bubbles are sprayed on the fire occurrence side of the partition sheet. The cooling water is sprinkled on the outer seat surface, which is the opposite side to the fire occurrence side, so that the fire extinguishing foam sprinkled on the inside of the seat is not dissipated by the cooling water, but the cooling water is sprinkled on the outer seat surface. With this, it is possible to enhance the fireproof property, smoke-impermeable property, and heat-impermeable property of the partition sheet against a fire. In addition, here, the surface side facing the center of the target section is the inside, and the opposite surface side is the outside.

[Basic Concept of Embodiment]
The sheet unfolding device 10 of the present embodiment is installed to suppress a fire that has occurred in a space such as a warehouse, and uses a cloth-like body having fire resistance, fire resistance, heat resistance, or smoke resistance. The partition sheet 14 that is the partition means, and one end of the partition sheet 14 is fixed by the fixing member 15 that is the fixing means to the apparatus main body 12 that is the main body means that is fixed at a predetermined position such as the ceiling side of the protective space. Also, the partition sheet 14 is held in a non-expanded state in which it is rolled in a roll shape or folded in a bellows shape by a holding member 16 which is a holding means, and when the protective space is fired, a latch release operation portion 18 which is a developing means. Since the holding of the partition sheet 14 is released and the other end side is dropped by so as to expand so as to partition any target section including the fire occurrence place in the protective space, when a fire occurs in the protective space, By expanding the partition sheet 14 so as to partition the target area including the fire occurrence area from the surrounding area, a partition area is formed in the protective space, and flame spread, smoke shield, and heat shield prevent spread of fire and smoke diffusion. You can expect it.

Further, by spraying a fire extinguisher such as water for extinguishing fire or a fire extinguishing agent into the partition sections partitioned by the expansion of the partition sheet 14, it is possible to suppress the scattered fire extinguishing agent from being scattered around, and It enables concentrated spraying to reliably suppress fires and extinguish fires, and suppresses/prevents the extinguishing agent from splashing around, thus minimizing water damage and the like.

Further, the partition sheet 14 developed at the time of fire is sprayed with a coolant from a coolant spraying head 28, which is a coolant spraying means, so that the partition sheet 14 is wetted, thereby further improving the flame-shielding property, smoke-shielding property, and heat-shielding property of the partition sheet 14. You can

[Sheet development device]
As shown in FIG. 1, in the sheet unfolding device 10, a device body 12 which is a body means is fixed to a ceiling surface side of a protective space, and one end of a partition sheet 14 which is a partition means is fixed to the device body 12 by a fixing means. The partition sheet 14 is fixed by a certain fixing member 15, and the partition sheet 14 is hung at two positions on the left and right by a holding member 16 which is a holding means using a wire or a rope below the apparatus main body 12 in a non-deployed state wound in a roll shape. Is held in a state.

The partition sheet 14 may be in a non-deployed state by winding the partition sheet 14 around a rotating shaft, releasing the latch of the rotating shaft in the event of a fire, and dropping and deploying the partition sheet 14 by its own weight. Further, the partition sheet 14 of the sheet unfolding device 10 may be held in a non-expanded state by folding it in a bellows shape, and in a fire, the holding may be released and dropped and unfolded.

The partition sheet 14 is a sheet that can withstand high heat of 1200° C., for example, and is also called a fireproof sheet, a fireproof curtain, a fireproof curtain, or the like. It should be noted that the partition sheet 14 may have a heat resistance performance of, for example, several hundreds of degrees even if it is 1200° C. or less.

Further, the weight of the partition sheet 14 is, for example, about 35 kilograms when the size is 5 meters in width and 10 meters in length, and since the steel shutter of the same size exceeds 600 kilograms, it is about 1/20. The seat developing device 10 can be easily installed in the protective space.

The holding member 16 using a wire or a rope has one end fixed to the apparatus main body 12 and the other end passing through the underside of the partition sheet 14 wound in a roll shape, which is a latch release actuating unit provided in the apparatus main body 12 as a deployment means. It is detachably held by 18 and is prevented from coming off. The latch release operation unit 18 releases the latch by energizing a solenoid, for example, by an operation signal from the outside.

When the sheet unfolding device 10 activates the latch release actuating portion 18 by an actuation signal from the outside in the event of a fire, one end of the partition sheet 14 is fixed to the apparatus body 12 and the other end of the partition sheet 14 is held by the holding member 16. Is released, and as shown in FIG. 2, it falls by its own weight and is deployed downward.

When the holding member 16 is released from the latch release actuating portion 18, the partition sheet 14 having a weight of about 35 kg drops and deploys with one side fixed, so that the conventional partition sheet 14 driven by a motor is operated. Compared to unwinding, it can be dropped more quickly and expanded vertically.

Here, the length of the partition sheet 14 expanded as shown in FIG. 2 is measured to be longer than the installation height of the sheet expansion device 10 in the protective space so as to have an extra length. This is because there are cases in which equipment such as luggage and equipment is placed on the floor that is the lower surface of the protective space, and when the partition sheet 14 is dropped and deployed, even if there is equipment on the floor, a slack in the sheet creates a gap. This is to make it difficult to do.

Further, the sheet spreading device 10 is provided with a cooling agent spraying head 28 which is a cooling agent spraying means for spraying, for example, cooling water as a cooling agent to the partition sheet 14 deployed in the event of a fire. The coolant spraying heads 28 are provided on the pipes 29 taken out on both sides of the device body 12, and the cooling pipes 44 are connected to the pipes 29 through the on-off valve 46 through the device body 12 to provide a coolant supply facility in case of fire. When the cooling water is supplied from 40 (described later), one side of the partition sheet 14 that is expanded as shown by the one-dot chain line in FIG. 2, for example, the right side of the partition sheet 14 in FIG. ), the cooling water is sprayed as a coolant on the outer seat surface (the left seat surface in the figure) which is the opposite side to the fire occurrence side.

The cooling water sprayed from the cooling agent spray head 28 flows down along the outer sheet surface while wetting the outer sheet surface of the expanded partition sheet 14 substantially uniformly. The partition sheet 14 may be coated with resin or the like on the surface of the cloth and may be uncoated. When the uncoated partition sheet 14 is used, the cooling water sprayed from the coolant spraying head 28 spreads. The sheet surface of the partition sheet 14 is wetted, cooling water is impregnated into the cloth texture of the partition sheet 14 to close the gap, the smoke shielding property is improved, and diffusion of smoke to the outside of the partition sheet 14 is suppressed. .. Further, the partition sheet 14 is cooled by impregnating the sprayed water and flowing down along the outer sheet surface, so that the flame shielding property and the heat shielding property are enhanced. Of course, a coated product can also obtain a predetermined effect.

Here, the reason why the cooling water is sprinkled on the outer sheet surface opposite to the fire occurrence side of the partition sheet 14 unfolded from the cooling agent spraying head 28 is that the partitioning sheet 14 is unfolded in the target compartment. Is spraying fire-extinguishing foam from a fire-extinguishing head 26 (described later). When the sprayed fire-extinguishing foam is splashed with cooling water from the coolant spraying head 28, the fire-extinguishing foam disappears. is there.

In addition, when the fire extinguishing water is sprayed in the partition section including the fire occurrence place partitioned by the expansion of the partition sheet 14, the cooling water may be sprayed on the inner seat surface or the inner surface of the seat surface. The cooling water may be sprinkled both on the outside and outside.

In the present embodiment, one cooling agent spraying head 28 is provided on each side of the sheet developing device 10, but a plurality of cooling agent spraying heads 28 may be arranged side by side according to the sheet width. Further, the cooling pipe 44 for the coolant spraying head 28 may be arranged outside without passing through the inside of the apparatus main body 12. Further, the on-off valve 46 may be built in the apparatus body 12 instead of being externally attached.

In addition, the release of the partition sheet 14 in the sheet deploying device 10 by the deploying means is performed by a fusible link that releases the hold by melting the fuse that receives heat from the fire, in addition to the operation signal from the outside during the fire. It may be operated. Further, it may be a composite type in which each method is combined depending on the use, scale and shape.

Further, the holding member 16 which is a holding means and the latch release actuating portion 18 which is a developing means are not limited to this, and an appropriate method can be adopted. For example, a tough and wide resin tape is used as a holding means, and the resin tape is hung and held through the lower side of the partition sheet 14 wound around the apparatus main body 12 in a roll shape. It is also possible to embed a heater wire in a position that traverses the partition, and in case of fire, melt the resin tape by energizing and heating the heater wire to release the partition sheet 14 and drop it so that the partition sheet 14 is expanded vertically.

[Installing a seat expansion device in a protected space]
FIG. 3 is an explanatory view showing the installation state of the sheet expanding device for the disaster prevention equipment. As shown in FIG. 3, a disaster prevention facility 20 using the sheet expanding apparatus 10 of the present embodiment is installed in a protected space 22 such as a large warehouse. Twelve sheet unfolding devices 10 for unfolding the partition sheet 14 at the time of a fire are arranged in a grid pattern on the upper plane which is the ceiling side of the protective space 22. The sheet expanding device 10 may be installed in a space position slightly below the ceiling surface other than the ceiling surface of the protective space 22.

Here, the sections of the protective space 22 corresponding to the grid-shaped arrangement of the sheet expanding apparatus 10 divided by the dotted line are target sections A1 to A9 partitioned by the expansion of the partition sheet 14 by the sheet expanding apparatus 10. The size and the number of target sections in the protective space 22 are arbitrarily determined according to the size of the partition sheet 14 developed by the sheet developing apparatus 10.

A sheet development control device 32 is provided corresponding to the sheet development device 10, and in the sheet development control device 32, when a fire occurs in any of the target sections A1 to A9, the target section A1 to A9 in which the fire has occurred is detected. In order to expand the partition sheet 14 so as to surround each of them, the relationship of the sheet expanding device 10 to be operated corresponding to the target sections A1 to A9 is stored in advance.

A fire detector 24 is installed on each of the ceiling surfaces of the target sections A1 to A9 in the protective space 22 shown in FIG. 3, and is connected to a signal line 45b drawn from a fire receiving panel 34.

The fire detector 24 has, for example, a transmission function and a unique address is set, and when a fire alarm is issued, by transmitting a fire signal including its own address, the fire reception panel 34 causes the fire reception panel 34 to detect the target sections A1 to A9. It is possible to identify the place where the fire has occurred, and based on this, a fire alarm is output, and at the same time, a transfer signal indicating the target section where the fire has occurred is transmitted to the fire extinguishing control panel 38.

Therefore, the seat development control device 32 surrounds the periphery of the target section where the fire has occurred, corresponding to any of the target sections A1 to A9 that is the place where the fire has occurred, based on the transfer signal received from the fire receiving panel 34. Thus, the sheet developing device 10 is operated to deploy the partition sheet 14.

A fire extinguishing head 26 for spraying a fire extinguishing agent such as water for extinguishing water or fire extinguishing bubbles is arranged on each of the ceiling surfaces of the target sections A1 to A9 in the protective space 22 shown in FIG. It is connected to the fire extinguishing pipe 42 from the fire extinguishing agent supply equipment 36 via.

The fire extinguishing agent supply equipment 36 is fire extinguishing pump equipment or foam fire extinguishing pump equipment. When a fire alarm is output from the fire receiving panel 34, fire extinguishing water is supplied by activation of the fire extinguishing pump equipment, or foam extinguishing pump equipment Upon activation, foam extinguishing liquid is supplied. The fire extinguishing pump equipment or the foam fire extinguishing pump equipment is started by a manual operation or a linked start by a transfer signal from the fire reception panel 34.

A signal line 45c drawn from the fire extinguishing control panel 38 is connected to the on-off valve 30. The fire extinguishing control panel 38 opens to the open/close valve 30 arranged in the target section where the fire has occurred, corresponding to any of the target sections A1 to A9 which is the fire occurrence location indicated by the transfer signal received from the fire receiving panel 34. A drive signal is transmitted to open the fire, and fire water or fire extinguishing foam is sprayed to the target area where the fire occurs. The activation of the fire pump and the activation of the opening/closing valve may be performed based on the activation signal transmitted from the seat deployment control device 32 to the fire control panel 38.

As the fire extinguishing means for spraying the extinguishing agent on the target sections A1 to A9, for example, a closed type sprinkler head may be provided for each of the target sections A1 to A9, or the water for extinguishing fire from the water discharge nozzle to the target sections A1 to A9. A water discharge gun device for discharging water may be provided.

Cooling water is supplied as a cooling agent from a cooling agent supply facility 40 to the cooling agent spraying head 28 provided in the sheet developing device 10 in the event of a fire, and the sheet surface of the partition sheet 14 expanded as shown in FIG. 2 is cooled. Spray cooling water as an agent.

The coolant supply equipment 40 is a water supply pump equipment, for example, is activated in conjunction with the fire extinguishing agent supply equipment 36 by the fire extinguishing control panel 38, and is supplied to the coolant spraying head 28 of the sheet developing device 10 via the cooling pipe 44. To supply. Further, a signal line (not shown) drawn from the fire extinguishing control panel 38 is connected to the on-off valve 46, and the fire extinguishing control panel 38 is connected to the fire occurrence location received from the fire receiving panel 34 by the transfer signal. In response to any of the target compartments A1 to A9, the open drive signal is transmitted to the opening/closing valve 46 (see FIG. 2) corresponding to the outer seat surface of the sheet expanding device 10 that partitions the target compartment in which the fire has occurred, to open. Then, the cooling water is sprinkled on the outer sheet surface of the expanded partition sheet 14. The on-off valve 46 is omitted in FIG. The extinguishant supply facility 36 and the coolant supply facility 40 may be shared, and similarly, the extinguishing pipe 42 and the cooling pipe 44 may be shared.

[Operation of disaster prevention equipment]
FIG. 4 is an explanatory view showing the operation of the sheet expanding device for expanding the partition sheet so as to surround the place where the fire has occurred, and the coolant spraying head 28 is not shown. FIG. 5 is a plan view showing the spraying of cooling water with respect to the expansion of the partition sheet of FIG.

As shown in FIG. 4, if a fire occurs in the target section A5 and the fire detector 24 corresponding to the fire reports a fire, a rectangular arrangement is provided on the ceiling surface above the target section A5 determined as the fire occurrence location. The latch release actuating portion 18 of the four sheet expanding devices 10 thus operated is released to release the latch of the holding member 16, and the holding of the partition sheet 14 wound in a roll is released and falls, so that the target section A5 The partition sheet 14 is developed so as to surround the four surfaces, and the periphery of the target section A5 is closed to form a partition section.

Therefore, the flame, smoke, and heat due to the fire generated in the target section A5 are blocked by the partition sheet 14 that surrounds and expands the surrounding area, and the release to the outside is suppressed, thereby forming a substantially fire-proof section. can do.

Further, in the target space A5 surrounded by the expansion of the partition sheet 14, since the fire extinguishing water or the fire extinguishing foam is sprayed from the fire extinguishing head 26 by the opening drive of the opening/closing valve 30, in the case of the protective space 22 such as a large warehouse, Even if the fire extinguishing head 26 is located at a high position close to the ceiling surface, for example, more than several meters, the fire extinguishing head 26 is scattered in the target section A5 surrounded by the partition sheet 14 without being scattered around, and is generated in the target section A5. It is possible to reliably suppress the fire that is occurring and extinguish the fire.

In addition, when the fire extinguishing water or the fire extinguishing foam is sprayed from the fire extinguishing head 26, it is hardly leaked to the surroundings by being shielded by the partition sheet 14 that surrounds the surroundings, and the damage caused by spraying the fire extinguishing water or the fire extinguishing foam is minimized. It is possible to limit it.

In the target section A5 whose periphery is surrounded by the expansion of the partition sheet 14, a gap is generated at the joint of the four partition sheets 14, but it is necessary to close this gap portion, for example, in the corner portion. The auxiliary partition sheet may be expanded and closed so as to cross the inside obliquely.

Further, as shown in FIG. 5, cooling water is sprinkled on the outer sheet surface from a coolant sprinkling head 28 provided on the outer side of the four sheet unfolding devices 10 surrounding the target section A5 and unfolding the partition sheet 14. By doing so, the flame-proof property, smoke-proof property, and heat-shielding property are enhanced, and by flowing down along the outer sheet surface, a high cooling effect is obtained and heat resistance is enhanced.

Furthermore, the weight of the partition sheet 14 increases due to the cooling water flowing down along the expanded partition sheet 14, and the force of pulling the sheet downward to expand the sheet increases the tension of the expanded partition sheet 14 to form a shape. Can be kept.
