Description

[Technical Field]

[0001] The present invention relates to a fire compartment penetration treatment sheet and a fire compartment material. [Background technology]

[0002] Conventionally, buildings are provided with fire compartments such as floors, walls, etc. The fire compartments prevent the spread of fire in the building in the event of a fire. In order to pass inserts such as cables and pipes through the fire compartment material, a fire compartment penetration part (penetration hole) may be provided in the fire compartment material. In order to suppress the spread of fire through the fire compartment penetration part, a fire compartment penetration measure member is used (for example, see Patent Document 1).

[0003] In Patent Document 1, the fire compartment penetration member is formed in a partition (fire compartment material) of a building and is used to suppress the spread of fire at the fire compartment penetration part through which the penetrating body passes. The fire compartment penetration member is made of a fire-resistant material and a retaining material. The fire-resistant material is a member having fire resistance. The fire-resistant material is preferably a thermally expandable member, and can be a sheet-like member.

[0004] The retaining material may be a sheet-like first substrate. For example, the first substrate may be made of a non-combustible material such as metal foil or glass cloth, a resin material such as polyethylene or polyvinyl chloride, or a composite of these. The retaining material may be laminated with a fire-resistant material to form a laminated structure. The laminated structure is connected so that the fireproof material faces the partition and the insert. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Publication No. 2022-126531 Summary of the Invention [Problem to be solved by the invention]

[0006] However, there is room for improvement in the fire spread suppression performance of the fire compartment penetration member of Patent Document 1.

[0007] The present invention has been made in consideration of such problems, and aims to provide a fire compartment penetration treatment sheet that efficiently prevents fires from spreading, and a fire compartment material that includes this fire compartment penetration treatment sheet. [Means for solving the problem]

[0008] In order to solve the above problems, the present invention proposes the following means. (1) Aspect 1 of the present invention is a fire compartment penetration treatment sheet comprising a heat-resistant sheet made of metal and a melting sheet placed on the heat-resistant sheet.

[0009] In this invention, for example, the fire prevention compartment penetration treatment sheet is connected to the hollow wall and the insert through the through hole so that the melting sheet faces the hollow wall and the insert. Here, "facing" does not only mean facing each other with a gap between them, but also means coming into contact with each other. For example, if a fire occurs on a first side of the fire compartment penetration treatment sheet opposite the hollow wall, the insert, the fire compartment penetration treatment sheet, and the hollow wall are heated, and the heat-resistant sheet of the fire compartment penetration treatment sheet withstands the heat from the fire and continues to block at least a portion of the gap between the insert and the periphery of the opening of the penetration hole in the hollow wall.

[0010] On the other hand, at least a part of the melting sheet of the fire compartment penetration treatment sheet melts due to the heat of the fire, and closes at least a part of the gap between the hollow wall and the insert and the heat-resistant sheet. Therefore, air is less likely to flow between the opening periphery of the through hole in the hollow wall and the insert, preventing flames and heat from the fire from reaching the second side of the hollow wall and effectively preventing the fire from spreading.

[0011] (2) Aspect 2 of the present invention is a fire compartment material comprising a fire compartment material main body having a through hole formed therein, an insert having a portion disposed in the through hole, and a first fire compartment material penetration treatment sheet and a second fire compartment material penetration treatment sheet which are the fire compartment material penetration treatment sheets described in (1), wherein the first fire compartment material penetration treatment sheet is connected to a first main surface of the fire compartment material main body and to the insert so that the molten sheet faces the fire compartment material main body and the insert, respectively, and the second fire compartment material penetration treatment sheet is connected to a second main surface of the fire compartment material main body and to the insert, respectively, so that the molten sheet faces the fire compartment material main body and the insert.

[0012] In this invention, for example, when a fire breaks out on the first main surface side of the fire compartment material body, the insert, the first fire compartment penetration treatment sheet, and the fire compartment material body are heated. The heat-resistant sheets of the first fire compartment penetration treatment sheet and the second fire compartment penetration treatment sheet withstand the heat caused by the fire and continue to block at least a part of the gap between the insert and the opening periphery of the penetration hole in the fire compartment material body. On the other hand, at least a portion of the melting sheet of the first fire compartment penetration treatment sheet melts due to the heat from the fire, sealing at least a portion of the gap between the fire compartment material body and the insert and the heat-resistant sheet of the first fire compartment penetration treatment sheet. Therefore, air is less likely to flow between the opening periphery of the through hole in the fire compartment material body and the insert, and flames and heat from a fire are prevented from reaching the second main surface side of the fire compartment material body.

[0013] The heat-resistant sheet of the second fire compartment penetration treatment sheet withstands the heat of a fire and continues to block at least a part of the gap between the opening periphery of the penetration hole in the fire compartment material body and the insert. In this way, the spread of the fire can be effectively prevented.

[0014] (3) Aspect 3 of the present invention is a fire compartment material comprising a fire compartment material body having a through hole formed therein, a pipe material at least a portion of which is disposed in the through hole, a fire compartment penetration treatment sheet as described in (1) which is disposed between the opening peripheral edge of the through hole in the fire compartment material body and the pipe material, protruding beyond the pipe material on both sides in the axial direction of the pipe material and covering the entire circumference of the pipe material, an insert having a portion disposed within the pipe material, and fixing members for fixing the fire compartment penetration treatment sheet in contact with the insert body to the insert body on both sides in the axial direction, wherein the fire compartment penetration treatment sheet is disposed so that the molten sheet faces the pipe material.

[0015] In this invention, for example, when a fire breaks out on the first axial side of the fire compartment material body, the insert, the fire compartment penetration treatment sheet, the fire compartment material body, and the fixing member are heated. The fixing members fix the fire compartment penetration treatment sheet to the insert on both axial sides. The heat-resistant sheet of the fire compartment penetration treatment sheet withstands the heat caused by the fire and continues to block at least a part of the gap between the insert and the periphery of the opening of the penetration hole in the fire compartment material body.

[0016] On the other hand, at least a portion of the melting sheet of the fire compartment penetration treatment sheet melts due to the heat from the fire, and seals at least a portion of the gap between the pipe material and the insert and the heat-resistant sheet of the fire compartment penetration treatment sheet. Therefore, air is less likely to flow between the pipe material and the insert, and flames and heat from a fire are prevented from reaching the second side in the axial direction of the fire compartment material body. In this way, the spread of the fire can be effectively prevented.

[0017] (4) Aspect 4 of the present invention is a fire compartment material comprising a fire compartment material body having a through hole formed therein, a pipe material at least a portion of which is disposed in the through hole, a fire compartment penetration treatment sheet as described in (1) which is disposed between the opening periphery of the through hole in the fire compartment material body and the pipe material and covers the entire circumference of the pipe material, an insert having a portion disposed within the pipe material, and heat-resistant tape attached to the insert and the fire compartment penetration treatment sheet on both sides of the axial direction of the pipe material, and the fire compartment penetration treatment sheet is disposed so that the melting sheet faces the pipe material.

[0018] In this invention, for example, when a fire breaks out on the first axial side of the fire compartment material body, the insert, the fire compartment penetration treatment sheet, the fire compartment material body, and the heat-resistant tape are heated. The heat-resistant tape is attached to the insert and the fire compartment penetration treatment sheet on both axial sides. The heat-resistant sheet of the fire compartment penetration treatment sheet withstands the heat of the fire and continues to block at least a part of the gap between the insert and the periphery of the opening of the penetration hole in the fire compartment material body.

[0019] On the other hand, at least a portion of the melting sheet of the fire compartment penetration treatment sheet melts due to the heat from the fire, and seals at least a portion of the gap between the pipe material and the insert and the heat-resistant sheet of the fire compartment penetration treatment sheet. Therefore, air is less likely to flow between the pipe material and the insert, and flames and heat from a fire are prevented from reaching the second side in the axial direction of the fire compartment material body. In this way, the spread of the fire can be effectively prevented. [Effects of the Invention]

[0020] The fire compartment penetration treatment sheet and fire compartment material of the present invention can efficiently prevent the spread of fire. [Brief explanation of the drawings]

[Figure 7] FIG. 10 is a half cross-sectional side view of a wall according to a third embodiment of the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0022] (First embodiment) Hereinafter, a first embodiment of a fire compartment penetration treatment sheet and a fire compartment material according to the present invention will be described with reference to Figs. 1 to 3, taking as an example a case where the fire compartment material is a wall. As shown in Fig. 1, a wall 10 of this embodiment is used in a building 1. The configuration of the building 1 is not limited as long as it includes the wall 10. For example, the building 1 includes columns, beams, and floors (not shown), and the wall 10. The columns are made of H-shaped steel or the like. The columns extend upward from a foundation (not shown). The beams are made of H-shaped steel or the like and extend along a horizontal plane. The ends of the beams are joined to the columns.

[0023] The floor is made of reinforced concrete or the like and is flat. The floor is supported from below by beams. The wall 10 comprises a hollow wall (fire compartment material main body) 11, an insert 16, a first fire compartment penetration treatment sheet (fire compartment penetration treatment sheet) 21A, and a second fire compartment penetration treatment sheet (fire compartment penetration treatment sheet) 21B. The hollow wall 11 is formed in a flat plate shape. The hollow wall 11 has a first wall material 12 and a second wall material 13. For example, the wall materials 12 and 13 are formed in a flat plate shape using gypsum board. The fire compartment material body may be formed from components that can form fire compartments, such as ALC (Autoclaved Lightweight Aerated Concrete: lightweight aerated concrete cured with high-temperature, high-pressure steam), reinforced concrete, extruded cement boards, calcium silicate boards, concrete blocks, etc. The wall materials 12 and 13 are arranged so that their thickness direction is along a horizontal plane. A gap S1 is formed between the first wall material 12 and the second wall material 13.

[0024] A through hole 11a is formed in the hollow wall 11. The through hole 11a is composed of a first through hole 12a formed in the first wall material 12 and a second through hole 13a formed in the second wall material 13. For example, the through holes 12a and 13a have a circular shape when viewed in the thickness direction of the wall materials 12 and 13, and overlap each other. It should be noted that the hollow wall 11 may be formed of a single wall material. The shape of the through-hole 11a (through-holes 12a, 13a) is not limited to this. Hereinafter, the outer surface of the hollow wall 11 facing the first wall material 12 will be referred to as the first main surface 12b. The outer surface of the hollow wall 11 facing the second wall material 13 will be referred to as the second main surface 13b. The first main surface 12b and the second main surface 13b are surfaces facing in the thickness direction of the wall materials 12, 13. The second main surface 13b is the surface of the hollow wall 11 opposite to the first main surface 12b.

[0025] For example, the inserter 16 is a pipe. For example, the inserter 16 is made of polyvinyl chloride resin, polyethylene resin, polybutene resin, or a steel pipe. For example, the melting point of the inserter 16 is about 160°C to 250°C. The inserter 16 extends along a horizontal plane and is disposed in the through-hole 11a of the hollow wall 11. The inserter 16 protrudes beyond the hollow wall 11 on both sides in the thickness direction of the hollow wall 11. In other words, a portion of the inserter 16 is disposed in the through-hole 11a of the hollow wall 11. The insert may be a cable or the like.

[0026] In this embodiment, the configuration of the first fire compartment penetration treatment sheet 21A and the configuration of the second fire compartment penetration treatment sheet 21B are plane symmetrical with respect to the reference plane S6 along the hollow wall 11. For this reason, the configuration of the first fire compartment penetration treatment sheet 21A is indicated by adding the capital letter "A" to the numeral of the reference symbol. The configuration of the second fire compartment penetration treatment sheet 21B corresponding to the first fire compartment penetration treatment sheet 21A is indicated by adding the capital letter "B" to the same numeral as the numeral of the first fire compartment penetration treatment sheet 21A. This avoids redundant explanations. For example, a heat-resistant sheet 22A (to be described later) of the first fire compartment penetration treatment sheet 21A and a heat-resistant sheet 22B (to be described later) of the second fire compartment penetration treatment sheet 21B are symmetrical with respect to the reference plane S6.

[0027] 1 and 2, the first fire compartment penetration treatment sheet 21A has a heat resistant sheet 22A and a melting sheet 23A. The heat resistant sheet 22A and the melting sheet 23A are each formed in a sheet shape (flat plate shape). The heat-resistant sheet 22A is formed of a metal foil such as aluminum, an aluminum alloy, etc. For example, the heat-resistant sheet 22A can have a certain level of rigidity at a temperature of 600° C., which is expected in the event of a fire.

[0028] Melting sheet 23A is made of a synthetic resin such as LLDPE (Linear Low-Density PolyEthylene). Melting sheet 23A is placed on heat-resistant sheet 22A. The melting point of LLDPE is approximately 80°C to 120°C. The first fire prevention compartment penetration treatment sheet 21A is configured by laminating a heat resistant sheet 22A and a melting sheet 23A. As shown in Figure 2, the first fire compartment penetration treatment sheet 21A has a slit 21aA formed in it that extends from the outer peripheral edge of the first fire compartment penetration treatment sheet 21A to the center of the first fire compartment penetration treatment sheet 21A when viewed in a plane.

[0029] 1, the first fire compartment penetration treatment sheet 21A is connected to the first main surface 12b of the hollow wall 11 and the insert 16 so that the fusible sheet 23A faces the first main surface 12b of the hollow wall 11 and the insert 16. Here, facing does not only mean facing each other with a gap between them, but also means coming into contact with each other. At this time, the insert 16 is passed through the slit 21aA of the first fire compartment penetration treatment sheet 21A, and a part of the first fire compartment penetration treatment sheet 21A is wrapped around the insert 16. It is preferable that the first fire compartment penetration treatment sheet 21A seals the through hole 11a of the hollow wall 11. The first fire prevention compartment penetration treatment sheet 21A is fixed to the hollow wall 11 and the penetration body 16 by fasteners 26A such as staples. The first fire prevention compartment penetration treatment sheet 21A and the insert 16 may be fixed together with a metal tape having an adhesive layer on one side of a metal foil, a resin binding band, or the like.

[0030] The second fire compartment penetration treatment sheet 21B has a heat resistant sheet 22B and a melting sheet 23B which are configured in the same manner as the heat resistant sheet 22A and the melting sheet 23A of the first fire compartment penetration treatment sheet 21A. The second fire prevention compartment penetration treatment sheet 21B is connected to the second main surface 13b of the hollow wall 11 and the insert 16 so that the fusible sheet 23B faces the second main surface 13b of the hollow wall 11 and the insert 16, respectively. The wall 10 is supported from below by the floor and beams.

[0031] Next, the function of the wall 10 configured as above will be described. 3, when a fire breaks out on the first main surface 12b side of the hollow wall 11, the insert 16, the first fire compartment penetration treatment sheet 21A, and the hollow wall 11 are heated. The heat-resistant sheets 22A and 22B of the fire compartment penetration treatment sheets 21A and 21B withstand the heat caused by the fire and continue to block at least a part of the gap between the insert 16 and the opening periphery of the through hole 11a in the hollow wall 11.

[0032] On the other hand, at least a part of the melting sheet 23A of the first fire compartment penetration treatment sheet 21A melts due to the heat of the fire, and closes at least a part of the gap between the hollow wall 11 and the insert 16 and the heat-resistant sheet 22A of the first fire compartment penetration treatment sheet 21A. Whether the melting sheet 23B of the second fire compartment penetration treatment sheet 21B melts or not depends on how the heat of the fire is transmitted. Therefore, air is less likely to flow between the opening periphery of the through hole 11a in the hollow wall 11 and the insert 16, and flames and heat from a fire are prevented from reaching the second main surface 13b side of the hollow wall 11.

[0033] As described above, the wall 10 of this embodiment can efficiently prevent the spread of fire.

[0034] In addition, in the first fire compartment penetration treatment sheet 21A of this embodiment, for example, the first fire compartment penetration treatment sheet 21A is connected to the hollow wall 11 and the insert 16 so that the molten sheet 23A faces the hollow wall 11 and the insert 16, for a hollow wall 11 having an insert 16 passed through the through hole 11a. For example, if a fire breaks out on the first side of the first fire compartment penetration treatment sheet 21A, which is the opposite side of the hollow wall 11 from the hollow wall 11, the insert 16, the first fire compartment penetration treatment sheet 21A, and the hollow wall 11 are heated. The heat-resistant sheet 22A of the first fire compartment penetration treatment sheet 21A withstands the heat from the fire and continues to block at least a part of the gap between the insert 16 and the opening periphery of the through hole 11a in the hollow wall 11.

[0035] On the other hand, at least a part of the melting sheet 23A of the first fire compartment penetration treatment sheet 21A melts due to the heat of the fire, and closes at least a part of the gap between the hollow wall 11 and the insert 16 and the heat-resistant sheet 22A. Therefore, air is less likely to flow between the opening periphery of the through hole 11a in the hollow wall 11 and the insert 16, preventing the flames and heat from the fire from reaching the second side of the hollow wall 11, and effectively preventing the fire from spreading.

[0036] (Second embodiment) Next, a second embodiment of the present invention will be described with reference to FIGS. 4 to 6. The same components as those in the above embodiment are designated by the same reference numerals, and a description thereof will be omitted. Only the differences will be described. 4, a wall 30 of this embodiment includes a pipe material 31, a fire compartment penetration treatment sheet 36, and fixing members 41A and 41B instead of the fire compartment penetration treatment sheets 21A and 21B and fixing devices 26A and 26B in each configuration of the wall 10. The pipe material 31 and the fire compartment penetration treatment sheet 36 constitute a fire compartment penetration treatment unit 39. The pipe material 31 is made of a synthetic resin such as vinyl chloride resin and is formed into a tubular shape. The pipe material 31 is arranged so that the axis O1 of the pipe material 31 is along the thickness direction of the hollow wall 11. The middle portion of the pipe material 31 in the axis O1 direction is arranged in the through-hole 11a of the hollow wall 11. The pipe material 31 protrudes from the hollow wall 11 on both sides in the axis O1 direction. The entire pipe material 31 may be disposed in the through-hole 11a.

[0037] The fire compartment penetration treatment sheet 36 has a heat resistant sheet 37 and a melting sheet 38 which are configured in the same manner as the heat resistant sheet 22A and the melting sheet 23A of the first fire compartment penetration treatment sheet 21A. In this example, the fire compartment penetration treatment sheet 36 is larger (longer in the direction of the axis O1) than the first fire compartment penetration treatment sheet 21A, and no slits are formed in the fire compartment penetration treatment sheet 36. The fire compartment penetration treatment sheet 36 is disposed between the periphery of the opening of the through hole 11a in the hollow wall 11 and the pipe material 31, and covers the entire periphery of the pipe material 31. The fire compartment penetration treatment sheet 36 is disposed so that the fusible sheet 38 faces the pipe material 31. The fire compartment penetration treatment sheet 36 protrudes on both sides in the direction of the axis O1 beyond the pipe material 31. The protruding portions of the treatment sheet 36 are in contact with the outer peripheral surface of the insert 16. The fire compartment penetration treatment sheet 36 may be heat-sealed to the outer peripheral surface of the pipe material 31 .

[0038] In this embodiment, a middle portion (part) of the inserter 16 in the direction of the axis O1 is disposed inside the tubular member 31. The inserter 16 protrudes from the tubular member 31 on both sides in the direction of the axis O1. A wire is used for the fixing member 41 A. The fixing members 41A and 41B fix the fire prevention compartment penetration treatment sheet 36 in contact with the insert 16 to the insert 16 on both sides in the direction of the axis O1. The fixing member may be a metal tape having an adhesive layer on one side of a metal foil. The wall 30 may be provided with sealing members 43A and 43B shown in Fig. 4. The sealing members 43A and 43B fix the hollow wall 11 and the pipe material 31 (fire compartment penetration treatment sheet 36).

[0039] For each configuration of the wall 30, if the fire compartment penetration processing unit 39 shown in Figure 5 is manufactured in advance at a factory or the like, the wall 30 can be constructed by passing the fire compartment penetration processing unit 39 and the insert 16 through the penetration hole 11a of the hollow wall 11, making construction easier.

[0040] Next, the function of the wall 30 configured as above will be described. 6, when a fire breaks out on a first side of the hollow wall 11 in the direction of the axis O1, the insert 16, the fire compartment penetration treatment sheet 36, the hollow wall 11, and the fixing member 41A are heated. The fixing members 41A and 41B fix the fire compartment penetration treatment sheet 36 to the insert 16 on both sides in the direction of the axis O1. The heat-resistant sheet 37 of the fire compartment penetration treatment sheet 36 withstands the heat caused by the fire and continues to block at least a part of the gap between the insert 16 and the opening periphery of the through hole 11a in the hollow wall 11.

[0041] On the other hand, at least a portion of the melting sheet 38 of the fire compartment penetration treatment sheet 36 melts due to the heat from the fire, sealing at least a portion of the gap between the pipe material 31 and the insert 16 and the heat-resistant sheet 37 of the fire compartment penetration treatment sheet 36. Therefore, air is less likely to flow between the pipe and the insert 16, and flames and heat caused by a fire are prevented from reaching the second side of the hollow wall 11 in the direction of the axis O1. In this way, the spread of the fire can be effectively prevented.

[0042] (Third embodiment) Next, a third embodiment of the present invention will be described with reference to FIG. 7. The same components as those in the previous embodiment are designated by the same reference numerals, and a description thereof will be omitted. Only the differences will be described. As shown in FIG. 7, a wall 50 of this embodiment includes heat-resistant tapes 51A and 51B instead of the fixing members 41A and 41B in each configuration of the wall 30. In this example, the fire compartment penetration treatment sheet 36 has the same length as the pipe material 31, and the fire compartment penetration treatment sheet 36 does not protrude beyond the pipe material 31 on either side in the direction of the axis O1. The sealing members 43A and 43B fix the hollow wall 11 and the fire compartment penetration treatment sheet 36. It should be noted that the wall 50 does not necessarily have to be provided with the sealing members 43A and 43B.

[0043] For example, the heat-resistant tapes 51A and 51B may be metal tapes each having an adhesive layer on one side of a metal foil. The heat-resistant tapes 51A and 51B are attached to the insert 16 and the fire compartment penetration treatment sheet 36 on both sides in the direction of the axis O1, respectively.

[0044] Next, the function of the wall 50 configured as above will be described. For example, if a fire breaks out on a first side in the direction of the axis O1 relative to the hollow wall 11, the insert 16, the fire compartment penetration treatment sheet 36, the hollow wall 11, and the heat-resistant tape 51A are heated. The heat-resistant tapes 51A and 51B are attached to the insert 16 and the fire compartment penetration treatment sheet 36, respectively, on both sides in the direction of the axis O1. The heat-resistant sheet 37 of the fire compartment penetration treatment sheet 36 withstands the heat caused by the fire and continues to block at least a part of the gap between the insert 16 and the opening periphery of the through hole 11a in the hollow wall 11.

[0045] On the other hand, at least a portion of the melting sheet 38 of the fire compartment penetration treatment sheet 36 melts due to the heat from the fire, sealing at least a portion of the gap between the pipe material 31 and the insert 16 and the heat-resistant sheet 37 of the fire compartment penetration treatment sheet 36. Therefore, air is less likely to flow between the pipe 31 and the insert 16, and flames and heat caused by a fire are prevented from reaching the second side of the hollow wall 11 in the direction of the axis O1. In this way, the spread of the fire can be effectively prevented.

[0046] Although the first to third embodiments of the present invention have been described above in detail with reference to the drawings, the specific configurations are not limited to these embodiments, and the present invention also includes modifications, combinations, deletions, etc. of the configurations within the scope of the gist of the present invention. Furthermore, it goes without saying that the configurations shown in each embodiment can be used in appropriate combinations. For example, in the first to third embodiments, the fire compartment material is a wall, but the fire compartment material is not limited to this and may be a floor or the like.
