The present invention relates to a fire prevention compartment structure for forming a suitable fire prevention compartment in a space having an obstacle.
[0002]
[Prior art]
Various buildings and facilities are equipped with various fire prevention measures to prevent fires from occurring and to prevent the spread of fire. For example, there are sprinklers for performing fire extinguishing activities, and there are fire doors and fire walls to prevent the spread of fire.
[0003]
By the way, there is a fireproof screen as a kind of the latter fire wall, and the fireproof screen is normally wound or folded and stored, and is drawn out when a fire breaks out to isolate the fire occurrence place. As described above, the fireproof screen defines a preset fireproof section to prevent similar burning.
[0004]
[Problems to be solved by the invention]
However, such a conventional fire protection compartment structure partitions a space where there is no obstacle such as a passage, and the fire prevention compartment can be formed easily and reliably.
[0005]
However, in buildings and the like that place importance on functional aspects in factories and the like, truss beams, pipes, ducts, pipes, etc. are arranged in the vicinity of the ceiling. In this way, the space where the beams and pipes are arranged is always in a state where the connectivity is ensured, but when trying to form in the fire-proof section in the event of a fire, for example in the fireproof screen, the truss beam There was a problem that fire prevention compartments could not be formed properly due to obstructions such as pipes, ducts and pipes.
[0006]
Therefore, the present invention has been made in view of such a conventional problem, and even when there is an obstacle in a space where a fire prevention compartment is to be formed, the fire prevention compartment is appropriately formed when a fire occurs. It aims at providing the fire prevention division structure of the space part with an obstacle which can do.
[0007]
[Means for Solving the Problems]
In order to achieve such an object, in the fire protection compartment structure of the space with an obstacle shown in claim 1 of the present invention, in a building where an obstacle exists in the space where the fire protection compartment is to be formed, A large number of non-flammable or flame retardant string-like bodies or belt-like bodies that are maintained in a wound state by a hanging shaft and are stored around the space and formed with a thermally foamed fire-resistant paint layer are removed from the hanging shaft in the event of a fire. By disposing in the space portion, the paint of the heat-foamable fire-resistant paint layer is foamed and expanded by high heat due to a fire to form a fire barrier.
[0010]
Further , in the fireproof compartment structure of the space portion with an obstacle as claimed in claim 2 of the present invention, in a building where an obstacle exists in the space portion where the fireproof compartment is to be formed, the heat melting property is normally used. Adhering a large number of non-flammable or flame retardant string-like bodies or belt-like bodies, which are kept in a wound state by being adhered with an adhesive and stored around the space and formed with a heat-foaming fire-resistant paint layer, in the event of a fire By disposing the agent in the space part, the paint of the heat-foamable refractory paint layer foams and expands due to high heat caused by a fire to form a fire barrier.
Furthermore, in the fire prevention compartment structure of the space part with the obstacle shown in claim 3 of the present invention, the lower part of the space part where the obstacle exists and the string-like body or the band-like body is disposed is A fireproof compartment is formed by the fireproof screen.

FIG. 3 is an enlarged view of the main part of the fire prevention compartment structure in a normal state, and FIG. 4 is an enlarged view of the main part of the fire prevention compartment structure when the fire prevention compartment is formed.
[0017]
That is, the fire protection compartment structure 10 of the present embodiment is provided in a space 16 where obstacles such as a duct 12 and a pipe 14 are present as shown in FIG. A large number of bodies 20 are suspended at a predetermined interval. And as shown in FIG. 3, the heat foamable fire-resistant paint layer is comprised by apply | coating the heat-foamable fire-resistant paint 22 to each of these string-like bodies 20. Of course, the string-like body 20 is sufficiently soft and easily flexible.
[0018]
Here, the heat-foamable fire-resistant paint 22 is foamed and expands in volume by several tens of times when high heat is applied during a fire or the like. This heat-foamable fire-resistant paint 22 itself is well known, and a mixture of a binder, a flame retardant, a foaming agent, a carbonizing agent, and a filler in a predetermined ratio is used. For example, vinyl toluene-butadiene copolymer or vinyl toluene-acrylic acid ester copolymer is used as a binder, and ammonium polyphosphate as a flame retardant, melamine as a foaming agent, dipentaerythritol as a carbonizing agent, and as a filler. Titanium dioxide is used. Some of these mixtures are mixed with chlorinated paraffin as a plasticizer.
[0019]
The fire protection compartment structure 10 is applied to a building such as a factory where importance is placed on the functional aspect, and the duct 12 and the pipe 14 as the obstacle communicate with each other at an upper position near the ceiling 18 of the space 16. Is arranged in. The space portion 16 is normally used as a passage or the like, and is a space portion 16 having communication properties in consideration of the necessity of circulating conditioned air for air conditioning. Therefore, it is necessary to shield the space 16 including the duct 12 and the pipe 14 communicated as a whole when a fire occurs.
[0020]
Then, when attaching the string-like body 20, as shown in FIG. 1, the section P other than the arrangement portion of the duct 12 and the pipe 14 hangs the string-like body 20 a from the ceiling portion 18 which is the upper end of the space portion 16. To do. On the other hand, the section Q of the arrangement portion of the duct 12 and the pipe 14 first hangs the string-like body 20b from the ceiling portion 18 to the upper ends of the duct 12 and the pipe 14, and further from the lower ends of the duct 12 and the pipe 14. Also, the string-like body 20c is suspended. Of course, the upper ends of the string-like bodies 20a and 20b are attached to the ceiling 18 via heat-resistant adhesive or screws, and the lower ends of the duct 12 and the pipe 14 are similarly used for the string-like body 20c. Attached to.
[0021]
In the fireproof compartment structure 10 of the space part with an obstacle according to the present embodiment having the above configuration, a large number of non-combustible string-like bodies 20a from the ceiling part 18 and the duct 12 and the pipe 14 of the space part 16 are provided. The space 16 is entirely covered by hanging down 20b, 20c, and a heat-foaming fire-resistant paint 22 is applied to each of the string-like bodies 20a, 20b, 20c. Accordingly, when high heat at this time acts on the heat-foamable fire-resistant paint 22 due to the occurrence of a fire, the heat-foamable fire-resistant paint 22 expands and expands several tens of times, and as shown in FIG. The thermally foamable refractory paints 22 of the shaped bodies 20 adhere to each other. When the heat-foamable fire-resistant paint 22 is foamed, the foamed layer expands while avoiding obstacles such as the duct 12 and the pipe 14 and surrounds the duct 12 and the pipe 14 as shown in FIG. 24 is formed. The fire wall 24 closes the entire space 16 and exhibits a high heat insulating function, thereby preventing fire spread.
[0022]
On the other hand, in the normal state, the soft string-like body 20 is suspended in the space 16 as if it were warm. For this reason, these string-like bodies 20 do not interfere with the duct 12 and the pipe 14, and conditioned air or the like can freely flow through the gaps of the string-like bodies 20, and the communication can be ensured. .
[0023]
FIG. 5 shows another embodiment, in which the same components as those in the above embodiment are denoted by the same reference numerals and redundant description is omitted. FIG. 5 is a front view showing the fire prevention compartment structure.
[0024]
That is, in the fire protection compartment structure 10a of this embodiment, as shown in FIG. 5, the upper ends of a large number of string-like bodies 20 coated with a heat-foamable fire-resistant paint 22 are connected to the ceiling portion 18 respectively, and a warm curtain-like curtain body. On the other hand, the warm curtain 26 is wound up and stored.
[0025]
Therefore, in this embodiment, the string-like body 20 to which the heat-foamable fire-resistant paint 22 is applied is attached to the ceiling portion 18 as a warm curtain 26, and the warm curtain 26 is normally rolled up and stored as indicated by a solid line. Since the warm curtain 26 is removed from the space portion 16 at normal times, the space portion 16 is in a completely connected state. Then, the warm curtain 26 stored in the event of a fire is lowered and disposed in the space 16 as indicated by a two-dot chain line, and as described in the above embodiment, the warm curtain 26 is heated with high heat from the fire. The heat-foamable fire-resistant paint 22 applied to the string-like body 20 of the body 26 expands and can form a fire wall. As a method for lowering the warm curtain 26, for example, a hanging shaft (not shown) for maintaining the curtain 26 in the rolled-up state is removed, or the string-like bodies 20 in the rolled-up state are attached with a hot-melt adhesive to maintain the rolled-up curtain 26. In addition, various methods such as a mechanism in which the string-like body 20 descends when the adhesive is melted by the heat at the time of the fire, the main point is that the rolled up curtain 26 descends at the time of the fire. What should I do?
[0026]
By the way, when the warm curtain 26 is lowered, the string-like body 20 easily bends and can flexibly surround the duct 12 and the pipe 14 as shown in the figure, and the thermally foamable fire-resistant paint 22 is foamed. At this time, the fire wall can be formed by appropriately surrounding the duct 12 and the pipe 14.
[0027]

FIG. 6 is a front view showing a fireproof compartment structure in a normal state, and FIG. 7 is a front view showing the fireproof compartment structure when a fireproof compartment is formed.
[0028]
That is, in the fire protection compartment structure 10a of this embodiment, as shown in FIGS. 6 and 7, the upper end portions of a large number of string-like bodies 20 coated with a heat-foamable fire-resistant paint 22 are connected to each other to form a warm curtain 26. On the other hand, a rail 28 is attached to the ceiling portion 18 in the left-right direction, and the warm curtain 26 is attached to be movable along the rail 28. Then, as shown in FIG. 6, the warm curtain 26 is always collected and stored at the end in the left-right direction. In the present embodiment, the left end portion is used, but it may be divided into two from the center portion and stored in both end portions.
[0029]
By the way, in this embodiment, the length of the string-like body 20 is set so as to be slightly lower than the lower ends of the duct 12 and the pipe 14 that become obstacles because the string-like body 20 is movable. The individual string-like bodies 20 can get over the duct 12 and the pipe 14 as the warm curtain-like body 26 moves.
[0030]
Therefore, in this embodiment, the string-like body 20 to which the heat-foamable fire-resistant paint 22 is applied is movably attached to the ceiling portion 18 as a warm curtain 26, and normally the warm curtain 26 is shown in FIG. Since the warm curtain 26 is removed from the space portion 16 in a normal state, the space portion 16 is in a completely connected state. Then, the warm curtain 26 stored in the event of a fire is pulled out and disposed in the space 16 as shown in FIG. 7, so that the warm curtain as a result of the high heat from the fire as described in the above embodiment. The heat-foamable fire-resistant paint 22 applied to the 26 string-like bodies 20 expands and can form a fire wall.
[0031]
By the way, when pulling out the warm curtain-like curtain body 26, the string-like body 20 easily bends and gets over obstacles, so that the duct 12 and the pipe 14 can be flexibly surrounded as shown in FIG. When the foamable fire-resistant paint 22 is foamed, the duct 12 and the pipe 14 can be appropriately surrounded to form a fire wall.
[0032]
By the way, although each said embodiment disclosed the case where the heat-foamable fireproof paint 22 was apply | coated to the string-like body 20, it replaces with this string-like body 20, and the same function can be exhibited. it can. In addition, the fireproof compartment structures 10 and 10a of the above embodiments are replaced with new ones after the heat-foamable fireproof paint 22 is foamed due to a fire. Further, the fire protection compartment structures 10 and 10a are suitable for application to the space 16 where the obstacles such as the duct 12 and the pipe 14 are arranged. It goes without saying that it is good.
[0033]
FIG. 8 shows still another embodiment, in which the same components as those in the above embodiment are denoted by the same reference numerals and redundant description is omitted. FIG. 8 is a front view showing the fire prevention compartment structure. The fire prevention compartment structure 10b of this embodiment shows a case where a steel material 30 or a metal mesh 32 is employed as the string-like body or the belt-like body. That is, the metal mesh 32 is disposed so as to surround the portion through which the pipe 14 and the duct 12 penetrate. That is, the metal mesh 32 can be regarded as a structure in which a large number of incombustible or incombustible string-like bodies or belt-like bodies are arranged in an oblique direction. A truss 34 is provided above the metal mesh 32 in the horizontal direction between the metal mesh 32 and the ceiling portion 18, and this truss 34 also becomes an obstacle when forming a fire prevention compartment. And in this embodiment with respect to such a truss 34, in the said truss 34, many steel materials 30 which can also be grasped | ascertained as a nonflammable or a flame-retardant string-like body or strip | belt-shaped body are arranged in a horizontal direction. It is installed. The steel material 30 and the metal mesh 32 are, of course, coated with the heat-foamable fireproof paint 22. Therefore, even in the space portion 16 in which an obstacle such as the pipe 14, the duct 12, and the truss 34 exists in a space where a fire prevention section is to be formed, the use of the metal mesh 32 and the steel material 30 allows It is possible to form a fire barrier made of the heat-foamable fire-resistant paint 22 similar to the above.
[0034]
Further, in the embodiment of FIG. 8, a fireproof screen 36 made of a flame retardant / nonflammable cloth or the like that can be wound up and stored is provided at the lower end position of the metal mesh 32 below the space portion 16, and a fire is generated. Sometimes, the fireproof screen 36 can be lowered to form a fireproof compartment, so that even the space 16 where obstacles such as the pipe 14, duct 12, truss 34, etc. are present can be entirely converted into a series of fireproof compartments. Can be configured.
