Description

  The present invention, for example, in a device installation room in which a plurality of fire protection target devices such as motors are arranged side by side, partitions a device installation space by arranging a fire barrier member between the plurality of fire protection target devices arranged side by side. It relates to a certain partition fire prevention equipment.

Conventionally, in order to partition the equipment installation space, it is conceivable to form a fire wall by fixing it to a floor in a state where a fireproof board is erected (a well-known common technique).
However, when the equipment installation space is narrow and partitioned, the fire prevention wall is considered to be an obstacle when repairing or checking the equipment subject to fire prevention or performing fire extinguishing activities due to the occurrence of a fire accident. As a result, workability was poor, and it was difficult to perform workability quickly due to obstacles because the work equipment and the like were too narrow and were damaged by hitting the installed fire barrier.
Therefore, it has been proposed to install a plurality of fireproof cloths made of heat-resistant fibers as fireproof partition members between fireproof target devices (appropriate literature cannot be found).

With the above-described installation of the fireproof cloth, even when work equipment or the like comes into contact with the work in a narrow space, the fireproof cloth can be prevented from being damaged by the flexibility, and the function as a partition wall can be maintained.
However, although fireproof cloth is generally made of glass fiber or silica fiber, when a fire occurs in any of a plurality of fireproof devices to be installed side by side, Although it is possible to prevent the spread of fire within a short period of time, the heat insulation is low (flame insulation is high, but the heat insulation is low), and if the fire continues, there is a risk that the adjacent fire prevention equipment is heated and spread.

  Accordingly, an object of the present invention is to provide a partition fire prevention equipment that solves the above-described problems, has high heat insulation properties, and is not easily damaged by contact with work equipment or the like.

  According to a first characteristic configuration of the present invention, in a device installation room in which a plurality of fire protection target devices are arranged side by side, a fire protection partition member is disposed between the plurality of fire protection target devices arranged in parallel to partition the device installation space. The partition wall fire-proofing equipment is made of a heat-foaming fire-resistant paint mainly composed of a flexible resin on the opposing surfaces of a pair of heat-resistant cloth made of heat-resistant fibers arranged side by side without any restriction. A foamed fireproof paint layer is formed, a pair of the fire barrier members arranged side by side are provided, and a heat insulating space is formed between the pair of fire barrier members.

According to the first characteristic configuration of the present invention, since the fire-resistant paint layer is flexible, the whole is flexible. For this purpose, the maintenance of the fire prevention target device and the work for extinguishing the fire are performed. Even when the work equipment is brought into contact with the fire barrier member when performing in the space, the fire barrier member can be prevented from being damaged.
Moreover, even if a fire breaks out in the equipment installation space, the fireproof coating layer foams and increases its thickness by heating while exhibiting flameproofness with the fireproof cloth, and the adjacent fireproof equipment spreads out by exhibiting heat insulation. Can be prevented.

  According to a second feature of the present invention, the fire-resistant paint comprises a foaming agent and a reaction catalyst made of ammonium polyphosphate or melamine phosphate, a softening agent made of a plasticizer, a carbonizing agent made of a carbohydrate or a polyhydric alcohol, and xylene. A solidification reaction promoting material containing a flexible resin material made of a urethane-based composite polymer and a solvent made of xylene is mixed with the main material containing the solvent made of and reacted.

  According to the second characteristic configuration of the present invention, by mixing the main material and the solidification reaction promoting material, a flexible fire-resistant paint layer is formed by reacting in a short time, and the fire-resistant cloth By integrating the layers, the fire barrier member can be formed quickly. In addition, since a flexible resin material made of a urethane-based composite polymer is used for the fireproof paint, not only the workability is improved by curing in a short time, but the fireproof paint layer formed is Since there is elasticity in addition to flexibility, even if work equipment or a worker hits the fire barrier member, the impact force can be reduced, and it becomes easy to prevent accidents during work as much as possible.

  According to a third characteristic configuration of the present invention, the fireproof cloth is a woven cloth made of silica fiber.

  According to the third characteristic configuration of the present invention, the fireproof cloth, which is a woven cloth made of silica fiber, is more thermally than a fireproof cloth made of, for example, general fiberglass yarn, rock wool, asbestos or the like. Durability, chemical stability and electrical insulation are high, and fire resistance can be maintained at a high level.

  According to the fourth feature of the fire prevention equipment of the present invention, the fire barrier member is suspended and supported from the ceiling between the plurality of fire protection target devices arranged side by side, and the suspension support portion includes the fire barrier member. It is in a place where it is detachable.

According to the fourth characteristic configuration of the present invention, as the fire protection equipment, the fire barrier member is suspended and supported from the ceiling, so that work equipment, workers, etc. are in contact with the fire barrier member. However, for example, as an external force acts on warmth, the external force accompanying the contact can be prevented from reaching the fire barrier member, and damage can be easily avoided.
In addition, when an external force is applied, the fire barrier member suspended and supported from the ceiling is moved to release the external force, so that the obstacles in the work can be reduced even in a small space.

  In addition, in the equipment installation room, for example, when performing repair work on equipment subject to fire prevention, the fire barrier member can be removed from the suspension support part, so the work space during repair work can be expanded and work can be performed more freely. And workability can be improved.

It is the whole longitudinal cross-sectional view of fire prevention equipment. (A)-(f) is a partial longitudinal cross-sectional view of various fire prevention partition members. It is a graph which shows the fireproof performance of various fireproof partition members.

Embodiments of the present invention will be described below with reference to the drawings.
As shown in FIG. 1, for example, in a device installation room in which a plurality of fire protection target devices 1 such as a pump P and a motor M that drives the pump P are arranged in parallel, a fire may have occurred from some devices. In such a case, it is required to dispose a device installation space by disposing a fire barrier member 2 between a plurality of fire protection target devices 1 arranged in parallel so that adjacent devices do not spread. When a fire occurs, the space becomes an atmosphere of about 900 ° C., so it is necessary to partition with a heat resistant material of 900 ° C. or higher.

  When the equipment installation room is partitioned by the fire barrier member 2 in a narrow space, when the worker enters the partitioned space for periodic inspections or repairs of the equipment, the fire barrier member 2 is For example, when a hard plate material such as a fireproof board is fixed, the worker or work equipment brought in by the worker may hit the fixed fire barrier member 2 and damage the fire barrier member 2. In order to reduce such obstacles, the fire barrier partition member 2 is made of silica fiber that is heat resistant up to about 1000 ° C. and has a flame spreadability. The fireproof cloth 3 formed by weaving heat-resistant yarn and formed with a heat-foamable fire-resistant paint mainly composed of a flexible resin is formed on both sides of the fire-resistant cloth 3 formed by weaving heat-resistant yarn. Partition members 2 are juxtaposed The fire barrier member is flexible even if it is installed in a suspended manner from the ceiling portion 5 of the equipment installation room between a plurality of fire protection target equipment 1 even if a worker or a work equipment carried by the worker contacts. It is configured to prevent the 2 from swinging back and forth to soften its collision force and break.

In addition, the fire barrier member 2 is detachably attached to the suspension tool 6 so that it can be removed from the suspension tool 6 to increase the work space when it becomes an obstacle in indoor work such as maintenance. It is designed to improve the sex.
In addition, in order to prevent the lower end part of the fire barrier member 2 from swinging back and forth unnecessarily, it may be temporarily fixed to the floor in a detachable manner.

The fire resistant paint comprises a foaming agent and a reaction catalyst made of ammonium polyphosphate or melamine phosphate, a softening agent made of a plasticizer, a carbonizing agent made of a carbohydrate or a polyhydric alcohol, and a solvent made of xylene. The main material is mixed and reacted with a solidification reaction accelerator containing a flexible resin material made of a urethane-based composite polymer and a solvent made of xylene.
The fire-resistant paint layer 4 formed by the fire-resistant paint becomes capable of being touched after 1 hour by the two-component mixed spraying of the main material and the solidification reaction promoting material, does not dissolve even when water is applied, and after 24 hours Solidification is completed while maintaining elasticity, and transport and overcoating are possible. Further, the solidified fireproof paint layer 4 becomes 70 (equivalent to a soft ball) by Shore A, and has elasticity and flexibility. For this reason, the coating film is hardly damaged and can withstand vibration and deformation.
In the fire barrier member 2, the coating film is carbonized at about 230 ° C. by receiving heat, and then the carbonized layer increases in thickness by several tens of times by foaming of the foam material to form a heat insulating layer.

  In order to partition the equipment installation space, as shown in FIG. 2 (f), the fireproof paint layer 4 formed on the entire surface of each side of the fireproof cloth 3 may be installed so that the ends overlap each other. In this case, there is a possibility that the fire-resistant paint layer 4 expands due to foaming due to heat reception, thereby forming a gap. On the other hand, when a plurality of fire barrier members 2 are installed side by side, as shown in FIG. In addition, the butt edge portion of the fire barrier members 2 arranged side by side is a first paint layer lacking portion in which a part of the fireproof paint layer 4 on one side of one fire barrier member 2 is missing along the top and bottom so that no gap is formed. 7 and a second paint layer lacking portion 8 in which a part of the fireproof paint layer 4 on the other side of the other fire barrier member 2 is missing along the top and bottom, and the first paint layer lacking portion 7 and the second paint are provided. By aligning the layer lacking portions 8, the plurality of fire barrier members 2 are arranged on the same surface without any gaps. It can be installed Te.

Next, the fire barrier performance of the fire barrier member 2 is divided into two closed spaces by the fire barrier member 2, the temperature in each space is measured, one space is used as a heat source, and the other space is timed. It was examined by an experiment to measure automatically.
In other words, as shown in FIG. 3, the first fire barrier member (FIG. 3) having only silica cloth as the experimental material and the second fire barrier member having 2 mm of fire-resistant paint applied to only one surface of the silica cloth (FIG. 3). 3)) and a third fire barrier member (FIG. 3 ●) in which 2 mm of fire-resistant paint is applied to both sides of the silica cloth, and a heat source is placed in the space on the one side and the other side The temperature of the space was measured over time.
According to the experiment, the first fire barrier member (Fig. 3) becomes about 170 ° C or higher in 6 minutes, and the second fire barrier member (Fig. 3 ○) becomes 170 ° C or higher in 20 minutes. In the partition member (FIG. 3 ●), the temperature did not rise to 170 ° C. or higher even in 45 minutes.
