Description

TECHNICAL FIELD The present invention relates to a disaster prevention device and disaster prevention equipment that closes the entrance and exit of a room in the event of a fire to suppress the spread and spread of the fire.

Conventionally, fire alarm equipment (Patent Document 1) and sprinkler fire extinguishing equipment (Patent Document 2) are known as disaster prevention equipment for suppressing and extinguishing fires that occur in monitored areas. When a fire alarm detects a fire, a fire alarm system closes a fire shutter to form a fire prevention zone and suppress the spread of the fire. In sprinkler fire extinguishing equipment, the sprinkler head opens in response to the hot airflow caused by the fire, spraying extinguishing water to suppress and extinguish the fire.

In addition, in the event of a fire occurring in an underground mall, etc., a water film is formed by spraying water from a row of sprinkler heads installed at the top of the passage in a direction across the passage, preventing the spread of the fire and the spread of smoke without damaging the evacuation route. A fire prevention zone formation system that suppresses fire protection is also known (Patent Document 3).

Furthermore, a disaster prevention curtain fire extinguishing system for mechanical parking lots is known (Patent Document 4). In this disaster prevention curtain fire extinguishing system, a disaster prevention curtain is installed at the opening of the parking area, and when a fire detector detects a fire in the parking area, the disaster prevention curtain lowers to close the opening and ejects extinguishing gas from the fire extinguishing nozzle. It is used to extinguish the fire.

(basic effect)
According to the disaster prevention device of the present invention, when a fire occurs when a fire occurs while the device is installed at the opening of a protected compartment (compartment boundary), for example, at the entrance/exit of a room, a cooling agent, for example, cooling water is supplied to the sheet. An impregnated layer is formed that allows the protective compartment to maintain its closing function even when exposed to fire flames or radiant heat, and by ensuring flame, smoke, and heat shielding properties for the outside of the protective compartment, it prevents the spread of fire and smoke diffusion. A preventive effect can be expected.

In addition, since the sheet is flexible, even if the entrance and exit of the room that is the opening of the protected compartment (compartment boundary) is closed, the sheet can be opened and evacuated easily, without damaging the evacuation route. The protected area can be closed without any damage.

In addition, the sheet is a cloth-like material that is lighter in weight than metal sheets, and can be easily manufactured into appropriate sizes that correspond to the size of openings such as doors, walls, windows, etc. can.

(Effect of first coolant impregnated part)
Additionally, when the coolant is supplied to the coolant distribution channel provided in the seat, the coolant, such as cooling water, flows down onto the seat from the openings provided at various locations in the coolant distribution channel, forming a coolant-impregnated layer and a water film. can do.

(Effect of seat structure)
In addition, by arranging the collapsible and deformable sheet piping between cloth-like bodies as a coolant flow path, the sheet can be manufactured simply and easily at low cost.

(Effect of ladder-shaped laying of sheet piping)
In addition, the sheet piping is laid in a ladder shape with multiple steps arranged along the flow direction of the coolant, and the coolant flows onto the sheet from multiple openings provided at various locations in the sheet piping. This makes it possible to form a coolant-impregnated layer and a water film substantially uniformly over substantially the entire surface of the sheet.

(Effect of wavy laying of sheet piping)
In addition, sheet piping is laid on the sheet by bending it in a wavy manner along the flow direction of the coolant, and the coolant flows down from multiple openings provided in various parts of the sheet piping onto the sheet, creating a ladder-like structure. This makes it possible to shorten the total length of the sheet piping compared to the installation of pipes, and to form a coolant-impregnated layer and water film almost uniformly over the entire sheet.

(Effect of suture fixation of sheet piping)
In addition, the sheet has cloth-like bodies stacked one on top of the other with the sheet piping interposed therebetween, and by sewing them together at predetermined locations, the sheet piping can be easily fixedly arranged inside the sheet.

In addition, a sheet is constructed by overlapping cloth-like bodies, and the overlapping cloth-like bodies are sewn vertically at predetermined division positions in the left and right direction, so that the coolant flow paths in the vertical direction are adjacent to each other. By forming multiple layers, the coolant is supplied to each coolant distribution path and flows down, without the need for sheet piping, allowing a coolant-impregnated layer and a water film to be formed on the sheet with a simple structure. can be formed.

(Effect of impregnated reinforced structure)
In addition, sheets can be made by overlapping cloth-like bodies with an impregnated body impregnated with a coolant, such as towel fabric with a raised structure, in between, to increase the water retention of the supplied coolant, such as cooling water, and to create a thick sheet. By forming a cooling water-impregnated layer and forming a water film on the surface of the sheet, the flame-proofing properties, smoke-blocking properties, and heat-blocking properties of the sheet can be further enhanced.

(Effect of third coolant impregnated part)
In addition, the sheet is made into a single cloth-like body, and the coolant is flowed down from the opening of the sheet piping arranged at the upper end of the cloth-like body onto both surfaces or either surface of the cloth-like body. Since only a single cloth-like body is required and no coolant distribution path such as sheet piping or stitching is required, the structure is simplified and manufacturing costs can be reduced.

(Effect of sheet cloth)
In addition, the cloth-like material used for the sheet has fire retardant properties, fire resistance, heat resistance, heat barrier properties, flame barrier properties, smoke barrier properties, or flame retardant properties. Together with the formation of a film, it can withstand flames and radiant heat from a fire, securely closing the protected area, and preventing the spread of fire by blocking the outside from flames, heat, and smoke. It becomes possible to secure an evacuation route.

(Effect of fixed seat installation)
In addition, a spread sheet is fixedly installed at the opening of a protected compartment (compartment boundary), such as the entrance/exit of a room, etc., and in the event of a fire, a coolant is supplied to the sheet to form a coolant-impregnated layer and a water film. Even in the case where a protective section is formed, it is possible to reliably close the protected compartment and provide flame, smoke, and heat insulation to the outside without obstructing the evacuation route.

(Effect of sheet development part)
In addition, the sheet deployment section holds the sheet in a predetermined position on the ceiling side above the opening of the protected compartment (compartment boundary), such as the entrance to a room, in normal times, and releases the retention in the event of a fire. By unfolding the sheet from above to below, it can function, for example, as a fire door that partitions the opening (section boundary) of a protected section where a fire has occurred. In addition, even if something is placed in the place where the disaster prevention equipment is installed, the cloth-like sheet is flexible, so if you measure it a little longer, you can prevent gaps from forming and prevent the fire from extinguishing and spreading. The degree of reduction in prevention, etc. can be suppressed.

(Effect of fire extinguishing water)
In addition, in the event of a fire, by supplying fire extinguishing water (cooling water) as a coolant, a coolant-impregnated layer and a water film are formed on the sheet, reliably closing the protected compartment and providing flame and shielding to the outside. Can block smoke and heat.

(Effects of disaster prevention equipment)
In addition, in the event of a fire, by remote control or manual operation, coolant is supplied from the coolant supply source to the disaster prevention equipment to form a coolant-impregnated layer and water film on the sheet, and close the protected area where the fire is occurring. can do.

(Effects due to the configuration of the piping opening/closing part)
In addition, in disaster prevention equipment, when a fire occurs in a protected area, the remote control valve can be changed from a closed state to an open state by remote control based on a control signal from the fire detection equipment. The sheet of the disaster prevention equipment can also be expanded to form a coolant-impregnated layer and a water film by manually opening the manual opening/closing valve.

(Effects of controlling coolant supply amount)
In addition, the opening degree of the control valve is controlled to change the amount of coolant supplied to the fire extinguisher, so for example, immediately after a fire breaks out and the sheet is deployed, the amount of coolant supplied is increased and the sheet is A coolant-impregnated layer and a water film are quickly formed over almost the entire surface of the sheet to ensure flame-blocking, smoke-blocking, and heat-blocking properties, and after a predetermined period of time, the coolant-impregnated layer and water film formed along the sheet are removed. The supply amount of cooling water is reduced to a level that can maintain the membrane, and the cooling water is prevented from flowing down the surface of the sheet and spreading over the floor surface more than necessary, making it possible to reduce the occurrence of water damage.

[Basic concept of embodiment]
First, the basic concept of the embodiment will be explained. The embodiments generally relate to disaster prevention equipment and disaster prevention equipment.

Here, "disaster prevention equipment" refers to equipment that protects people and property from fires, etc.; for example, it is installed at openings at the boundaries of protected areas, and in the event of a fire, the openings are closed and It suppresses the spread of fire and the spread of fire, and also allows the closing function to be maintained even when exposed to fire flames and radiant heat, and is a concept that includes fire doors and the like. Note that "closing" is a concept of closing part or all of an opening (compartment boundary). Furthermore, "disaster prevention equipment" refers to equipment that is equipped with disaster prevention equipment to protect people and property from fires, etc.; This includes equipment that closes openings, etc. by operating in conjunction with the In addition, "protection zone" is a zone to be protected by disaster prevention equipment, and is an outdoor or indoor zone with a certain extent, for example, a concept that includes zones such as rooms, corridors, and stairs of buildings. It is. Furthermore, an "opening at the boundary of a protected area" is an opening provided in the protected area that is an arbitrary boundary of the area, and more specifically, an opening through which people or objects pass. This concept includes door parts, sliding glass doors, windows, etc.

The disaster prevention equipment according to the embodiment includes a sheet and a coolant-impregnated part. Here, a "sheet" is a flexible, thin and wide thing that can be used to cover or cover; for example, it can be held in an undeployed state or This concept includes a cloth-like body that can be released from the unfolded state and put into the unfolded state. A "sheet" is composed of, for example, one or more cloth-like bodies, and the "sheet" here indicates a handling unit. That is, for example, when a plurality of cloth-like bodies are combined in advance and formed as one sheet (unit sheet), this is called "one sheet."

In addition, the "coolant impregnated part" is a part of the sheet's constituent elements (forms a part of the sheet), and supplies coolant to the sheet to form a coolant impregnated layer and a coolant film. One example is a coolant flow path and openings provided at various locations therein. Here, the term "coolant-impregnated layer" means that the coolant, such as cooling water, which is supplied to the coolant distribution channel of the sheet and flows down onto the sheet from various openings, impregnates the sheet and forms the cloth-like material that makes up the sheet. It is a layer formed to close the gaps in the fabric's weave structure and fibers. In addition, a "coolant film" is a phenomenon in which when a coolant is supplied to a sheet to form a coolant-impregnated layer, the coolant oozes out onto the sheet surface and flows down, spreading the coolant thinly along the sheet surface. This refers to the formation of a film, and the concept includes a water film formed on the sheet surface due to cooling water flowing down.

In addition, the "coolant distribution channel" is a path provided in the seat that forms part of the constituent elements of the seat and through which the coolant flows; for example, the "coolant distribution channel" is a seat pipe arranged between cloth-like bodies. It is a concept that includes. Here, the term "sheet piping" means that it can be crushed and deformed, and is normally crushed flat inside the aforementioned "sheet", but when coolant is supplied, it expands and opens the flow path. Refers to flexible piping that is formed. In addition, "openings" are coolant outflow ports that form part of the sheet's constituent elements and are provided at various locations in the coolant flow path, and are used to store the coolant supplied to the coolant flow path, such as cooling Water flows down onto the sheet to form a coolant-impregnated layer and a water film.

Further, the disaster prevention equipment includes a sheet deployment section. Here, the "sheet deployment unit" is a unit that normally holds the sheet in an undeployed state at a predetermined position on the border of a protected area, and releases the retention of the sheet in the non-deployed state and deploys it in the event of a fire outbreak. It is. For example, under normal circumstances, a sheet is rolled up and held at an opening at the boundary of a protected area, such as the ceiling above the entrance to a room, and in the event of a fire, the sheet can be released from its hold at one end ( While the upper end (upper end) is fixed, the other end (lower end) falls under its own weight and expands from above to below, thereby closing the opening.

Further, the disaster prevention equipment using the disaster prevention equipment includes coolant piping and a coolant supply source. Here, the "coolant pipe" is a pipe that supplies a coolant to disaster prevention equipment, and as an example, it supplies fire extinguishing water to the disaster prevention equipment as cooling water. Furthermore, the term "coolant supply source" refers to a source that supplies coolant to the coolant pipes, and includes, for example, a pressurized water supply device, an elevated water tank, a water pipe, and the like.

In the specific embodiment shown below, the "protected section" is a "room in a building," the "opening" is a "room entrance/exit," and the "coolant" is "cooling water." explain.

[a. Disaster prevention equipment]
As shown in FIG. 1, the disaster prevention equipment of this embodiment includes a disaster prevention device 10, a coolant supply source 22, and a coolant pipe 26 provided with a pipe opening/closing valve 24. In the following description, the illustrated horizontal direction of the disaster prevention device 10 shown in FIG. 1 will be referred to as the left-right direction, and the illustrated vertical direction (that is, the unfolding direction) will be referred to as the vertical direction.

(a1. Configuration)
The disaster prevention equipment 10 is installed at an opening at the boundary of a protected area, and protects people and property from fire by suppressing the spread and spread of fire when a fire occurs.For example, as shown in FIG. It is composed of a sheet 12, a holder 14, a coolant flow path 16, a stitched portion 18, and a coolant supply port 20. Coolant flow channels 16 become part of the sheet 12 component.

The sheet 12 is a flexible cloth-like body, and includes a coolant-impregnated portion that receives a coolant and forms a coolant-impregnated layer. The coolant impregnated section is composed of a coolant flow path 16 that is a component of the sheet 12 and an opening (not shown) provided therein, and forms a "first coolant impregnated section" for the sheet 12. The coolant distribution path 16 is a path for sending the coolant (here, cooling water (fire extinguishing water)) supplied from the coolant supply port 20 into the interior of the sheet 12 . Openings (not shown) are coolant outflow ports provided at various locations in the coolant flow path 16, and the coolant water supplied to the coolant flow path 16 flows down to the sheet 12 to impregnate the coolant. It forms an impregnated layer, and furthermore, by flowing down the cooling water that seeped out onto the surface of the sheet 12 during the formation of the coolant impregnated layer, a water film is formed as a coolant film on the surface of the sheet 12. be.

As an example, the sheet 12 is installed by the holder 14 at a predetermined position on the opening at the boundary of the protected compartment, for example, on the upper ceiling side of the entrance to the room, and in this embodiment, the sheet 12 is placed in the unfolded state. It has a predetermined length and width that is sufficient to close the opening.

The holder 14 is provided with a sheet unfolding section. The sheet deployment section normally holds the sheet 12 in a non-deployed state, and releases the holding of the sheet 12 and deploys it when a fire occurs.

Further, the holder 14 is provided with a coolant supply port 20, to which a coolant pipe 26 is connected from a coolant supply source 22 via a pipe opening/closing valve 24, so that cooling water can be supplied. The coolant supply source 22 supplies cooling water in the event of a fire, and can be of any suitable configuration, for example, a pressurized water supply device equipped with a pump, an elevated water tank, water pipes, etc. Can be used.

(a2. sheet)
The sheet 12 of the disaster prevention equipment 10 will be explained in more detail. Although the configuration and structure of this sheet 12 are arbitrary, for example, as shown in FIG. 1, a coolant flow path 16 is provided inside the sheet 12. For example, the coolant distribution path 16 is laid out in the form of a ladder with a plurality of steps, for example, four steps arranged along the flow direction of the coolant (direction from top to bottom), and each step has a plurality of steps. An opening (not shown) is formed.

The coolant flow path 16 is fixed by vertical seams 18 provided on both left and right sides of the sheet 12 and at predetermined intervals (excluding the coolant flow path 16). The seam portion 18 is a seam made by a sewing machine using waterproof thread (double-dashed line in the figure).

To explain in more detail, as shown in FIG. 2, the sheet 12 is made up of two cover sheets 28 and 30, which are cloth-like materials, stacked on top of each other. Between the cover sheets 28 and 30, for example, a sheet piping 32 is arranged to constitute the coolant flow path 16 shown in FIG. 1, and in this state, for example, as shown in FIG. They are integrated by stitching the stitched portions 18 in the direction.

The cover sheets 28 and 30 are cloth-like materials having fireproofing properties, fire resistance, heat resistance, or flame retardancy, and can withstand high heat of 1200°C, for example, and are called fireproof sheets, fireproof curtains, fireproof membranes, etc. are applicable, but are not limited to this. Further, the cover sheets 28 and 30 also have heat-shielding properties, flame-shielding properties, smoke-blocking properties, and the like.

(a3. Sheet piping)
The sheet piping 32, which is a part of the constituent elements of the sheet 12, will be described in more detail. The sheet piping 32 is a flexible piping that can be crushed and deformed, and expands when coolant flows therethrough. The structure and type of the sheet piping 32 are arbitrary, but for example, as shown in FIG. A plurality of openings 34 are formed at the bottom of each rung of the ladder shape.

In addition, since the sheet piping 32 is crushable and deformable, normally it is crushed within the sheet 12 and becomes flat as shown in FIG. 3(B). When the coolant 36 is supplied, as shown in FIG. ), it swells to allow the coolant 36 to flow through it, and the coolant 36, for example, cooling water, flows into the sheet 12 from the openings 34 provided at various locations, and impregnates the sheet 12 to form a coolant-impregnated layer. Furthermore, a water film is formed on the surface of the sheet 12.

FIG. 4(A) shows the seat 12 in normal conditions as seen from one side in the left and right direction, and since there is no coolant supplied to the coolant supply port 20, as shown in FIG. 3(B), The sheet piping 32 is crushed within the sheet 12 and is in a flat state.

When a fire occurs, as shown in FIG. 4(B), the sheet piping 32 expands due to the flow of the coolant supplied from the coolant supply port 20, and the coolant flows into the seat 12 from various openings. As shown in FIG. 4C, a coolant-impregnated layer 40 is formed by infiltrating the cover sheets 28, 30 and the space between them with the coolant 36 (here, fire extinguishing water as cooling water).

Furthermore, as shown by arrows in FIG. 4(B), the coolant flowing down into the sheet 12 from the various openings of the sheet piping 32 is blocked by the portions of the sheet piping 32 located below, and the surface of the sheet 12 The coolant oozes out and flows down, forming a water film 31. In this way, the coolant impregnates the cover sheets 28 and 30 to form a coolant-impregnated layer 40, and also forms a water film 31 on the surface of the sheet 12 due to the flow of the coolant leaked to the surface.

FIG. 5 shows in detail the manner in which the sheet piping 32, which is a part of the component of the sheet 12, is installed. Note that the sheet piping 32 is shown as a line, and the opening 34 of the sheet piping 32 is schematically shown as a triangular mark.

As shown in FIG. 2, with the sheet piping 32 arranged between the cover sheets 28 and 30, the sheet 12 is divided into upper and lower sections at predetermined division positions in the left and right direction when the sheet is unfolded, as shown in FIG. The seam portion 18 in the direction is sewn (excluding the sheet piping 32 portion). Thereby, the seat piping 32 can be easily fixedly arranged inside the seat 12. At least one opening 34 is formed between the split locations to allow coolant to flow therethrough.

(a4. Functions of disaster prevention equipment)
The disaster prevention function of the disaster prevention appliance 10 shown in FIG. 1 will be explained in more detail. The disaster prevention equipment 10 is installed at an opening at the boundary of a protected area, for example, at an entrance/exit of a room. If a fire occurs in this state, by opening the piping on-off valve 24 from the closed state, the refrigerant is supplied from the coolant supply source 22 to the extinguishing agent supply port 20 via the coolant pipe 26. Water for fire extinguishing purposes will be provided. The cooling water supplied to the seat 12 through the coolant supply port 20 flows through the sheet piping 32 that constitutes the coolant distribution path 16, and flows into the sheet 12 from openings 34 provided at various locations in the sheet piping 32. flows down, forming a coolant-impregnated layer 40 along the sheet 12, and also forming a water film on the surface of the sheet 12. In addition, since the sheet 12 is made of a cloth-like material having fireproofing properties, fire resistance, heat resistance, flame retardance, etc., the durability against flames and radiant heat caused by fire is increased, and the protected area can be reliably and continuously protected. It will be possible to close the In addition, it increases flame, smoke, and heat insulation properties for the outside, improving fire spread prevention and smoke diffusion prevention performance, making it possible to carry out even safer evacuation actions and initial firefighting operations.

In addition, since the sheet 12 is flexible, even if an opening at the border of a protected area, such as an entrance to a room, is closed, the sheet 12 can be opened to easily evacuate from within the closed area, and the evacuation route The protected area can be closed without compromising the Similarly, it is also possible to easily enter the closed area from outside the closed area to extinguish the fire.

Moreover, the sheet 12 can be made lightweight and simple by making it a cloth-like body that is lighter than a metal fire door.

In addition, the sheet piping 32 is laid in the sheet 12 so as to have a ladder shape in which a plurality of steps are arranged along the flow direction of the coolant, and the sheet piping 32 is installed in the sheet 12 through a plurality of openings 34 provided in the sheet piping 32 of each step. By flowing the cooling water, it becomes possible to form a coolant-impregnated layer and a water film substantially uniformly over substantially the entire surface of the sheet 12.

[b. Other installation forms of sheet piping]
Another example of the installation form of the sheet piping 32 that forms the coolant flow path 16 within the sheet 12 will be described in detail.

As shown in FIG. 6, in this disaster prevention device 10, sheet piping 32 is installed within the sheet 12 so as to form a rectangular wave shape along the flow direction of the coolant. The sheet piping 32 is sewn vertically at predetermined division positions in the left-right direction (excluding the portion of the sheet piping 32). At least one opening 34 is formed in the sheet piping 32 between adjacent division positions, through which the coolant flows.

According to the installation of the sheet piping shown in FIG. 6, the total length of the sheet piping 32 can be made shorter than that of the sheet piping shown in FIG. 5, which has a ladder shape.

(b2. Laying sheet piping exhibiting a triangular wave shape)
As shown in FIG. 7, in this disaster prevention device 10, sheet piping 32 is laid in the sheet 12 so as to form a triangular wave shape along the flow direction of the coolant. The sheet piping 32 is sewn vertically at predetermined division positions in the left-right direction (excluding the portion of the sheet piping 32). At least one opening 34 is formed in the sheet pipe 32 between adjacent dividing positions to allow coolant to flow between the dividing positions.

According to the triangular wave-shaped laying of the sheet piping shown in FIG. 7, the total length of the sheet piping 32 can be made shorter than that of the sheet piping shown in FIG. 5, which has a ladder shape. Note that the laying form of the sheet piping 32 on the sheet 12 is not limited to the above-mentioned ladder shape, rectangular wave shape, and triangular wave shape, but is arbitrary.

[c. Disaster prevention equipment that does not use sheet piping]
The disaster prevention device 10 that forms a coolant-impregnated layer on the sheet 12 without using sheet piping will be described in detail. This disaster prevention device 10 does not use sheet piping and forms a coolant distribution path within the sheet 12 only by the stitched portion, and forms a "second coolant impregnated portion" for the sheet 12.

As shown in FIG. 8(A), the sheet 12 has two cover sheets 28 and 30 stacked on top of each other in the same way as shown in FIG. The stitched portion 18 is stitched to form a plurality of vertical coolant flow paths 44 adjacent to each other. Further, each of the coolant distribution channels 44 is provided with an opening 42 schematically indicated by a triangular mark for supplying the coolant, and a coolant supply pipe 45 from the coolant supply port 20 is connected via the holder 14. .

When cooling water is supplied to the coolant supply port 20 when a fire occurs, the coolant flows down from the openings 42 of each coolant flow path 44 as shown by the arrows. As a result, as shown in the cross section taken along the line aa in FIG. is formed, and the cooling water leaking onto the surfaces of the cover sheets 28, 30 flows down to form a water film (not shown).

According to this embodiment, the structure is simple in that a plurality of coolant distribution channels 44 are formed adjacent to each other by the stitched portions 18 of the sheet 12 without requiring sheet piping, and the manufacturing cost can be reduced. Can be reduced.

[d. Disaster prevention equipment equipped with impregnated body]
Next, the disaster prevention device 10 including the impregnated body will be described in detail. As shown in FIG. 9(A), the sheet 12 of this disaster prevention device 10 has sheet piping 32 disposed between the cover sheets 28 and 30 in the same way as shown in FIG. 2, and also functions as an impregnated body. It is characterized in that a water-absorbing cloth 46 is arranged.

The water-absorbing cloth 46 is, for example, an impregnated body having a raised structure like a towel cloth, and the raised structure absorbs and retains a coolant, for example, cooling water, thereby achieving high water retention.

As shown in FIG. 9(B), the coolant-impregnated layer 40 is thicker than in the embodiment of FIG. is formed, and together with the water film 31 formed on the sheet surface, the flame-blocking properties, smoke-blocking properties, and heat-blocking properties of the sheet 12 can be further enhanced.

Note that in the embodiment of the disaster prevention equipment 10 shown in FIGS. 6 to 8 as well, the water-absorbing cloth 46 may be arranged as an impregnated body between the two cover sheets 28 and 30 that constitute the sheet 12.

[e. Disaster prevention equipment consisting of a sheet made of a single cloth-like material]
The disaster prevention device 10 having a sheet made of a single cloth-like body will be described in detail. As shown in FIG. 10, this disaster prevention device 10 is composed of a holder 14, a sheet 12 made of a single piece of cloth, a coolant supply port 20, and a sheet pipe 32 having a plurality of openings 34. The structure for causing the coolant to flow down the sheet surfaces on both sides of the sheet 12 is arbitrary, but for example, the upper end side of the sheet 12 is folded downward in half by a predetermined width L, and the inside of the folded in half is folded in the left and right direction. The sheet piping 32 is arranged in a straight line, and its periphery is sewn up with a seam section 18. A plurality of openings 34 are formed in the sheet piping 32 so as to be exposed on both sides of the sheet 12. The sheet piping 32 and the plurality of openings 34 provided in this manner constitute a "third coolant-impregnated part" for the sheet 12 made of a single cloth-like body.

In the event of a fire, the coolant supplied to the coolant supply port 20, here cooling water, flows into the sheet piping 32 and flows down from the opening 34 along each of the sheet surfaces on both sides of the sheet 12, as shown by the arrows. , a water film is formed along the surface of the sheet 12, and the cloth-like body constituting the sheet 12 is impregnated with cooling water to form a coolant-impregnated layer. The expansion of the sheet 12 is also assisted by the flow of cooling water through the sheet piping 32 (coolant flow path 16).

Note that the cooling water may flow down from the opening 34 of the seat pipe 32 onto both sheet surfaces as described above, or may flow down onto either one of the sheet surfaces.

[f. Sheet expansion part of disaster prevention equipment]
The sheet deployment section provided in the disaster prevention equipment 10 shown in FIGS. 1 to 10 will be described in more detail. The sheet deploying section normally holds the sheet 12 of the disaster prevention device 10 in a non-deployed state at a predetermined position on the border of the protected area, and releases the holding and deploys the sheet 12 when a fire occurs. Although the structure of this sheet unfolding section is arbitrary, for example, as shown in FIGS.

(f1. Structure of sheet expansion part)
The holder 14 is a box-shaped container whose longitudinal direction is the left-right direction, and forms a fixed part that is attached to the upper part of the ceiling of a room entrance or the like. The sheet 12 is fixed at one end to the holder 14 with a sheet fixing part 63. Normally, the sheet 12 is wound into a roll and in an undeployed state, and a sheet holding member using a wire or rope is attached to the underside of the holder 14. 64, it is held in a suspended state at multiple locations.

One end of the sheet holding member 64 is fixed to the holder 14, and the other end is attached to and detached from the sheet holding release part 66 on the opposite side of the holder 14 (opposite to the side where it is fixed) by passing the other end under the winding outer circumference of the sheet 12. It is held in The sheet holding release unit 66 operates in response to supply of coolant from the coolant pipe 26 and releases the holding of the sheet holding member 64.

When the sheet holding release unit 66 releases the holding of the sheet holding member 64, as shown in FIGS. The side (bottom edge) side falls due to its own weight and expands in the vertical direction (height direction). Note that a predetermined weight member may be provided on the lower end side of the sheet 12, and in this way, the fall of the lower end side of the sheet 12 and the stability of the sheet 12 after being expanded can be assisted.

(f2. Sheet holding release part)
The sheet holding release unit 66, which releases the holding state of the sheet 12 in the non-deployed state and deploys it, will be described in more detail. Although the configuration and structure of the sheet holding release section 66 are arbitrary, for example, as shown in FIG. 12, an actuator 68 that operates in response to supply of coolant is provided in the holder 14.

The actuator 68 operates in response to supply of coolant to release the holding of the sheet 12 and unfold it. The structure and type of this actuator 68 are arbitrary, but for example, a piston 72 is slidably incorporated into a cylinder 70 via a return spring 76, a cylinder chamber 70a is formed on one side of the piston 72, and a coolant supply port 78 is formed. A cooling pipe 26 is branched and connected to. An automatic drain valve 73 is provided for the cylinder chamber 70a. The automatic drain valve 73 closes when supplied with extinguishing agent exceeding a predetermined pressure, and opens when the pressure drops below the predetermined pressure.

The piston 72 has a rod 74 coaxially therewith. An opening 82 is provided in the front face of the holder 14, through which a portion of the rod 74 is visible and an operating stick 80 provided on the rod 74 is exposed for operation.

When holding the sheet holding member 64 on the rod 74, move the rod 74 to the left using the operation stick 80, and attach a retaining ring 64a, which is made by tying the tip of the sheet holding member 64 into a loop using a wire, to the rod 74. to hold the sheet 12 in an unexpanded state.

In the event of a fire, cooling water is supplied from the coolant pipe 26 to the cylinder chamber 70a, and the piston 72 is stroked to the left against the return spring 76, whereby the rod 74 comes out of the retaining ring 64a, and the seat holding member 64 is released, and the sheet 12 falls from the other end side due to its own weight and unfolds from above to below.

Note that the sheet holding and releasing section 66 is not limited to the above, but is arbitrary. For example, the sheet holding release unit 66 may release the holding of the sheet holding member 64 and unfold the sheet 12 by driving an electromagnetic solenoid or the like based on a control signal from a receiver.

Further, as the sheet unfolding structure of the disaster prevention equipment 10, other appropriate structures can be applied. For example, a structure may be adopted in which the sheet 12 is wound around a rotating shaft and the sheet 12 is unfolded by releasing the latch of the rotating shaft, or a structure in which the sheet 12 is unrolled and wound up by motor drive. Alternatively, the sheet 12 may be held in a bellows-like folded state, and then released and unfolded.

[g. Disaster prevention equipment]
Disaster prevention equipment using the disaster prevention equipment 10 shown in FIGS. 1 to 12 will be described in detail. Although the configuration and structure of this disaster prevention equipment are arbitrary, for example, as shown in FIG. configured.

The disaster prevention device 10 is installed at the opening of the protection compartment 48, for example, on the upper ceiling side of the entrance/exit 50 of the room, and under normal conditions, the sheet 12 is in a non-deployed state due to the sheet deployment structure shown in FIGS. 11 and 12. keeping.

A fire detector 52 is installed in the protected compartment 48 as fire detection equipment, and is connected to a receiver 54 . One end side of a coolant pipe 26 is connected to the coolant supply port 20 of the disaster prevention equipment 10, and the other end side is connected to the coolant supply port 20 through a parallel connection of a remote on-off valve 24a and a manual on-off valve 24b (not shown) that function as a pipe opening/closing part. In this embodiment, the coolant supply source is connected to, for example, water pipes.

When the receiver 54 receives a fire signal from the fire detector 52 and outputs a fire alarm, an open control signal is output to the remote on-off valve 24a connected to the control line to drive it from the closed state to the open state. By supplying water, the holding of the sheet 12 in the undeployed state is released, and as shown in the figure, the sheet 12 is deployed from the top to the bottom to close the entrance/exit 50 of the room. Further, the tap water supplied to the sheet 12 forms a coolant-impregnated layer and a water film on the sheet 12. For this reason, durability against flames and radiant heat caused by fire is increased, and it becomes possible to reliably and continuously close the protected section 48. In addition, it increases flame, smoke, and heat insulation properties for the outside, improving fire spread prevention and smoke diffusion prevention performance, making it possible to carry out even safer evacuation actions and initial firefighting operations. Furthermore, even if the entrance 50 of the room is closed, the sheet 12 is flexible, so the user can easily evacuate from the closed protected compartment 48 by opening the sheet 12. Similarly, it is also possible to enter the closed protected area from outside the closed protected area 48 to fight the fire. Further, for example, a fire extinguishing agent dispersing unit such as a fire extinguishing head may be separately provided to spray the extinguishing agent within the closed protection section 48. The extinguishing agent to be sprayed may be the same as the coolant, for example tap water.

The receiver 54 of the fire detection equipment operates for a predetermined period of time using a backup power source provided with a battery during a power outage. Therefore, even if a fire occurs during a power outage, the receiver 54 outputs an open control signal to the remote on-off valve 24a, and the sheet 12 of the disaster prevention device 10 is expanded by supplying tap water to remove the coolant-impregnated layer and water film. The protective compartment 48 can be closed.

The disaster prevention equipment of this embodiment includes a remote on-off valve 24a and a manual on-off valve 24b as piping opening/closing parts, and the case where these are connected in parallel is taken as an example. It's good to have something to prepare for. That is, it may be opened and closed only by the remote on-off valve 24a, or it may be opened and closed only by the manual on-off valve 24b. Of course, connection methods other than parallel connection are not prohibited.

[h. Disaster prevention equipment with fixedly installed sheets in unfolded state]
Disaster prevention equipment in which the sheet is fixedly installed in an unfolded state will be explained in detail. As another embodiment of the disaster prevention equipment, a disaster prevention device 10 with a sheet unfolded in advance is used. In this case, the expanding section can be omitted. The disaster prevention equipment 10 may be installed in any manner in the protected area, but as an example, it may be installed on a wall or the like that requires protection. Specifically, for example, the holder 14 of the disaster prevention equipment 10 is fixed to the upper ceiling side of the wall surface, and the lower end side of the sheet 12 whose upper end side is fixed to the holder 14 is pulled down and unfolded along the wall surface. A predetermined portion of the sheet 12 is screwed to a wall surface or the like. When a fire occurs, a coolant, in this case cooling water, is supplied to the sheet 12 to form a coolant-impregnated layer on the sheet 12 to prevent the spread of fire and smoke to the outside of the protected area, and to fix the sheet 12. Protect walls, etc. from fire.

[i. Control of cooling water supply]
An embodiment of the disaster prevention equipment that changes over time the amount of coolant supplied to the seat of the disaster prevention equipment will be described in detail. In the disaster prevention equipment shown in FIG. 13, the receiver 54 serves as a control unit that temporally changes the supply amount of coolant, here cooling water (tap water), to be supplied to the sheet 12 of the disaster prevention equipment 10 deployed when a fire occurs. Equipped with functions. For this reason, the remote opening/closing valve 24a provided in the coolant pipe 26 is a control valve whose opening degree can be adjusted, for example, an electric valve.

When a fire occurs, for example, the receiver 54 receives a fire signal from the fire detector 52 and outputs a fire alarm, and for a predetermined period of time, the remote opening/closing valve 24a is fully opened and the unfolded seat 12 is opened. supply cooling water. As a result, a coolant-impregnated layer and a water film are quickly formed over substantially the entire surface of the sheet 12, and flame-proofing, smoke-blocking, and heat-blocking properties are ensured.

After a predetermined period of time has elapsed, the receiver 54 reduces the opening degree of the remote on-off valve 24a to reduce the supply amount of cooling water to a predetermined supply amount that can maintain the coolant-impregnated layer and water film of the sheet 12. . Thereby, while continuing to cool the sheet 12, it is possible to prevent the cooling water from flowing down the sheet 12 more than necessary and spreading over the floor surface, thereby making it possible to reduce the occurrence of water damage.

In addition, if the fire spreads and the seat 12 is exposed to strong radiant heat or direct flame, the opening degree of the remote on-off valve 24a is increased by, for example, a predetermined operation on the receiver 54, Increase the amount of cooling water supplied to the seat 12. This maintains the coolant-impregnated layer and the water film, making it possible to reliably and continuously close the protected compartment 48 without compromising its durability against fire flames and radiant heat.

In addition, as another embodiment for controlling the amount of cooling water supplied to the seat 12, for example, a temperature sensor is installed at or near the seat 12, and the receiver 54 controls the opening and closing of the remote on-off valve 24a based on the temperature detected by the temperature sensor. The amount of cooling water supplied may be controlled by adjusting the temperature.

Further, as another embodiment of controlling the amount of cooling water supplied to the seat 12, the receiver 54 controls the remote opening/closing valve 24a to open and close at a predetermined period, and supplies cooling water to the seat 12 intermittently. Good too. For example, the remote on-off valve 24a is designed to intermittently supply cooling water to the extent that the coolant-impregnated layer and water film formed on the sheet 12 are not lost due to evaporation or the like even if the seat 12 receives flames or radiant heat from a fire. Control opening and closing. By intermittent supply of cooling water to the sheet 12 in this manner, the amount of cooling water supplied to the sheet 12 can be made appropriate, and when a coolant impregnated layer and a water film are formed on the sheet 12, it is possible to It reduces the amount of cooling water flowing down, making it possible to suppress the occurrence of water damage.
