Description

[Technical Field]

[0001] The present invention relates to a compartment penetration structure formed in a partition section of a building or the like, a compartment penetration material for forming the compartment penetration structure, and a construction method for the compartment penetration structure. [Background technology]

[0002] In buildings such as apartment complexes, office buildings, and schools, compartment penetrations are often installed in partitions such as walls to allow the passage of long objects such as cables and pipes. Compartment penetrations are required to be constructed with fire prevention measures (fire-resistant construction) to prevent the spread of fire to other compartments in the event of a fire in one compartment. Partitions are generally hollow walls, consisting of two walls with a hollow space between them.

[0003] A known method for making a compartment penetration fireproof is to fill the gap between the long insert and the penetration hole with an irregular filler such as fireproof putty, rock wool, or glass wool. When an irregular filler is used, a tubular member made of a fireproof material may also be placed between the inside of the penetration hole in each wall section and the insert (see, for example, Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6150933 [Patent Document 2] Patent No. 6348320 Summary of the Invention [Problem to be solved by the invention]

[0005] However, when unshaped filler is used for fireproofing of compartment penetrations, there is variation among workers, and sufficient fire resistance may not be achieved. Also, when installing fireproofing materials and their accessories within the structure, it is sometimes unclear to what extent they have been installed (quantity, thickness, length, etc.), or it is difficult to determine whether they have been installed according to regulations. Therefore, in order to confirm whether fireproofing materials have been installed according to regulations, it is necessary to destroy the compartment penetration structure and check the internal structure.

[0006] Additionally, to reduce variations among workers, there are kits that integrate predetermined quantities and sizes of components, but these tend to have a large number of components, which can easily lead to components being lost or forgotten to be installed, and there is also the problem of a lot of waste being generated because each kit is packaged separately.

[0007] Furthermore, in compartment penetration structures in which long inserts such as cables and piping are inserted, if the insert is moved after the compartment penetration structure is applied, the fire-resistant material installed inside may be displaced from its original position. External forces such as earthquakes may also cause the fire-resistant material to be displaced from its original position. Furthermore, if the fire-resistant material expands unevenly rather than uniformly, it may be displaced from its original position or fall off. Displacement of the fire-resistant material from its original position makes it difficult to achieve the fire-resistant performance desired for the compartment penetration fire-resistant structure.

[0008] Therefore, the present invention aims to provide a compartment penetration treatment structure, a compartment penetration treatment material, and a construction method for a compartment penetration treatment structure that can reduce variation in fire resistance performance and improve fire resistance performance.

DETAILED DESCRIPTION OF THE INVENTION

[0012] The present invention will be described in more detail below using embodiments.

[0013] [First embodiment] The compartment penetration structure according to the first embodiment of the present invention is a compartment penetration structure 10, as shown in FIG. 1, which is formed in a partition 11 of a building and has a compartment penetration portion 15, through which a long penetrating body 21 is inserted, having a fire-resistant structure.

[0014] The partition 11 in the compartment penetration structure of the present invention is a component that separates compartments (first compartment A and second compartment B) in the wall surface of a building, and has a compartment penetration 15 that penetrates from one outer surface 11A of the partition 11 to the other outer surface 11B. The partition 11 shown in FIG. 1 is a hollow wall and is composed of two wall materials (partition materials) 12A and 12B arranged with a gap (hollow portion 13) between them. Therefore, the compartment penetration 15 is composed of a through hole 13A formed in one wall material 12A, a through hole 13B formed in the other wall material 12B, and the hollow portion 13 between them. The outer surface of one wall material 12A forms the outer surface 11A of the partition 11, and the outer surface of the other wall material 12B forms the outer surface 11B of the partition 11. The through holes 13A and 13B may be, for example, circular, elliptical, or similar shapes. The through holes 13A and 13B on the outer surfaces 11A and 11B respectively constitute openings 13C and 13D of the compartment through-hole 15 provided in the partition 11.

[0015] In this specification, the fire-resistant structure 1 (in this embodiment, the fire-resistant material 3, the covering material 4, the retaining material 5, and the fixing members for fixing these, etc.) that is installed in the compartment penetration section 15 and forms the compartment penetration treatment structure 10 is sometimes collectively referred to as the compartment penetration treatment material. In addition, the following describes the configuration of the compartment penetration processing structure on one opening 13C side of the partition section 11, but in this embodiment, the configuration of the compartment penetration processing structure on the other opening 13D side is similar, so the description thereof will be omitted.

[0016] The compartment penetration structure 10 according to the first embodiment includes a fireproof structure 1 having a fireproof material 3, a covering material 4, and a retaining material 5 as a compartment penetration material.

[0017] [Fireproof material] The fire-resistant material 3 is a fire-resistant member that provides fire resistance to the compartment penetration portion 15 of the partition portion 11. The fire-resistant material 3 is preferably a thermally expandable member that expands when heated. The thermally expandable member prevents the spread of fire by expanding in the event of a fire. The thermally expandable member is preferably formed from a thermally expandable resin composition, as described below. The fire-resistant material 3 may also have adhesive properties.

[0018] As shown in FIG. 1 , the fire-resistant material 3 can be a sheet-like member. In this embodiment, the sheet-like fire-resistant material 3 is laminated on a retaining material 5, which is a sheet-like substrate, to form a laminated structure 30. The laminated structure 30, which is made up of the fire-resistant material 3 and the retaining material 5, is fixed to the partition 11. Examples of means for fixing the laminated structure 30, which is made up of the fire-resistant material 3 and the retaining material 5, to the partition 11 include known fixing means such as adhesives, pressure-sensitive adhesives, adhesive tapes, and fixing members such as tackers and screws. Here, the adhesives, pressure-sensitive adhesives, and adhesive tapes are preferably made of non-combustible, semi-non-combustible, or flame-retardant materials, and it is preferable to blend a flame retardant into the adhesive, pressure-sensitive adhesive, or the like. Furthermore, if the fire-resistant material 3 has adhesive properties, the fire-resistant material 3 may be directly fixed to the partition 11 by its adhesive force.

[0019] The laminated structure 30, which is made up of the fire-resistant material 3 and the retaining material 5, has slits 50 through which the inserts 21 are inserted, and at least one of the slits 50 extends to the outer edge of the laminated structure 30. The slits 50 are formed by cutting. The inserts 21 can be inserted into the laminated structure 30 through the slits 50 that extend to the outer edge of the laminated structure 30. The slits 50 may have a form that includes a hole through which the inserts 21 are inserted and a slit 50 that extends from the hole to the outer edge of the laminated structure 30.

[0020] As shown in FIG. 2 , the laminated structure consisting of the fire-resistant material 3 and the retaining material 5, into which the inserts 21 are inserted through the slits 50, is placed on the outer surface 11A of the partition 11 so as to cover the gap 13E between the opening 13C and the inserts 21 from the outside, thereby blocking the gap 13E between the opening 13C and the inserts 21 with the sheet-like fire-resistant material 3. The sheet-like fire-resistant material 3 is preferably placed so as to contact both the outer surface 11A of the partition 11 and the outer periphery of the inserts 21. By placing the sheet-like fire-resistant material 3 so as to contact the inserts 21 and the partition 11, the opening 13C of the partition 11 can be blocked, thereby improving and maintaining fire resistance.

[0021] The thickness of the sheet-like fire-resistant material 3 is not particularly limited, but is, for example, 1 to 50 mm, and preferably 5 to 30 mm. When the sheet-like fire-resistant material 3 has a thickness equal to or less than these upper limits, flexibility is imparted to the fire-resistant material 3, making it easier to insert the inserter 21 inside. When the thickness is equal to or more than the lower limits, fire resistance is more easily ensured.

[0022] [Covering material] The covering material 4 is a member that directly or indirectly covers at least a part of the fire-resistant material 3 provided in the partition portion 11. The covering material 4 may be arranged on the outer periphery of the fire-resistant material 3 and cover the outer periphery of the fire-resistant material 3. The covering material 4 is disposed on the outer side of the refractory material 3 and the holding material 5 with respect to the partition portion 11 , and covers at least a part of the refractory material 3 and the holding material 5 . The covering material 4 can be, for example, a sheet-like member as shown in Fig. 1. The covering material 4 is sheet-like and deformable, so that it can easily cover the fire-resistant material 3. The covering material 4 is fixed to any of the fire-resistant material 3, the retaining material 5, and the partition 11. Examples of means for fixing the covering material 4 include known fixing means such as adhesives, pressure-sensitive adhesives, adhesive tapes, and fixing members such as tackers and screws. The adhesives, pressure-sensitive adhesives, and adhesive tapes are preferably non-combustible, semi-non-combustible, or flame-retardant materials, and it is preferable to blend a flame retardant into the adhesives, pressure-sensitive adhesives, etc. Furthermore, as will be described later, the covering material 4 may be fixed by its own self-adhesive strength or by an adhesive layer of the covering material 4. In the configuration shown in FIG. 2, the covering material 4 is fixed to the retaining material 5.

[0023] 1, the covering material 4 has slits 40 through which the penetrating body 21 is inserted, and at least one of the slits 40 extends to the outer edge of the covering material 4. The slits 40 are formed by cutting. The covering material 4 allows the penetrating body 21 to be inserted into the covering material 4 through the slit 40 that extends to the outer edge.

[0024] The covering material 4 may be formed, for example, from a sheet-like substrate. Examples of the substrate include metal foils such as aluminum foil and copper foil, metal foil composites such as glass cloth and composites of metal foil and glass cloth such as aluminum-glass cloth, paper, cloth, and resin film. Among these, from the viewpoint of fire resistance, it is preferable that the covering material 4 be made of a non-combustible material, and specific examples include metal foil and metal foil composites. Non-combustible materials are those defined in the Building Standards Act and the Enforcement Order of the Building Standards Act. The thickness of the substrate is not particularly limited, but is, for example, 0.01 to 1 mm, and preferably 0.05 to 0.5 mm. When the noncombustible material layer has a thickness equal to or less than these upper limits, flexibility is imparted to the sheet-like member 3. When the noncombustible material layer has a thickness equal to or greater than the lower limits, fire resistance is more easily ensured.

[0025] Furthermore, the covering material 4 may have a layered structure in which a layer other than the substrate is provided, as long as the effect of the covering material 4 is not impaired. Specifically, the covering material 4 may have a layered structure in which a substrate and a fireproof material layer are laminated. In the case of the covering material 4 having a layered structure in which a substrate and a fireproof material layer are laminated, the substrate supports the fireproof material layer and transfers heat evenly to the fireproof material layer. In addition, in the layered structure, the substrate is preferably disposed as the outermost layer on the side opposite the partition portion 11. By disposing the substrate as the outermost layer of the sheet-like member 3, the fireproof material layer disposed on the inside can be well supported and heat can be transferred evenly to the fireproof material layer, thereby enabling the fireproof material to expand more uniformly. The fire-resistant material layer used in the covering material 4 is preferably a thermally expandable material that expands when heated. The thermally expandable material prevents the spread of fire by expanding in the event of a fire. The thermally expandable material is preferably formed from a thermally expandable resin composition, as described below. The fire-resistant material layer may also have adhesive properties. The thickness of the fire-resistant material layer is not particularly limited, but is, for example, 0.1 to 15 mm, and preferably 0.5 to 8 mm. When the fire-resistant material layer has a thickness equal to or less than these upper limit values, flexibility is imparted to the covering material 4. When the fire-resistant material layer has a thickness equal to or greater than the lower limit values, fire resistance is more easily ensured.

[0026] The covering material 4 can also be combined with other functional sheets to form a laminated structure. By providing the covering material 4 with other functional sheets, the covering material 4 can be given the functions of the other functional sheets without impairing its fire resistance. Examples of functional sheets include heat insulating sheets such as glass wool sheets and rock wool sheets, sound absorbing sheets, soundproof sheets, and sound insulating sheets.

[0027] As described above, the covering material 4 is preferably a sheet that can be deformed so as to cover the fireproof material 3, and is preferably flexible and easily deformable. The thickness of the covering material 4 is not particularly limited, but is, for example, 0.1 to 15 mm, and preferably 0.5 to 10 mm.

[0028] The covering material 4 may have an adhesive fire-resistant material layer or an adhesive layer. The adhesive fire-resistant material layer and the adhesive layer may constitute the outermost layer of the covering material 4. With the above configuration, the covering material 4 can be fixed to any of the fire-resistant material 3, the retaining material 5, and the insert 21 without using a fixing member separate from the covering material 4. Furthermore, by making the fire-resistant material layer itself adhesive, an adhesive layer is not required, which further simplifies the configuration of the covering material 4. When the covering material 4 has an adhesive fireproof material layer or adhesive layer on its outermost layer, a release sheet may be attached to the outermost layer. The release sheet may be peeled off from the outermost layer when in use.

[0029] As shown in FIG. 2, the covering material 4 surrounds the insert 21 so that the portion covering the fireproof material 3 is in contact with the insert 21, and is fixed to the insert 21 by a string-like member 22 wound around it from the outside. The string-like member 22 may be any bendable member, and is preferably a wire member including a wire. The wire member may be a metal wire alone, or a resin-coated wire such as Nejirikko (registered trademark) in which a metal wire is coated with resin, or a wire and fiber entangled member such as a maul. When a wire member is used, the covering material 4 can be fixed to the insert 21 simply by twisting or twisting it. In another embodiment (not shown), the covering material 4 surrounds the fire-resistant material 3 so that the portion thereof is in contact with the insert 21, and is fixed to the insert 21 by an adhesive tape wound around the outside. The adhesive tape preferably has a substrate and an adhesive layer provided on one side of the substrate. The substrate may be made of paper, resin film, cloth, or the like, or may be made of the non-flammable materials described above. The adhesive layer may be made of, for example, an acrylic adhesive, a urethane adhesive, a rubber adhesive, or a silicone resin adhesive. The adhesive may also contain a known flame retardant. In another embodiment not shown, the covering material 4 may have a portion covering the opening 13C of the compartment penetration portion 15 that surrounds the penetrating body 21 so as to be in contact with the penetrating body 21, and may be fixed to the penetrating body 21 by a fixing member such as a stapler or screw installed from the outside. Furthermore, in another embodiment not shown, the covering material 4 may have a portion covering the opening 13C of the compartment penetration portion 15 that surrounds the insert 21 so as to be in contact with it, and may be fixed by an adhesive fire-resistant material layer or adhesive layer arranged on the inside.

[0030] The covering material 4 preferably covers a part of the fire-resistant material 3, making the part of the fire-resistant material 3 invisible from the outside. Specifically, it is preferable that the covering material 4 covers the part of the fire-resistant material 3 through which the insert 21 is inserted, thereby improving the design of the compartment penetration part 15 and the fire resistance performance of the compartment penetration part 15. On the other hand, the covering material 4 may cover a portion of the fire-resistant material 3 so that it is visible from the outside. Specifically, the covering material 4 may be configured so that the end face of the fire-resistant material 3 is visible from the outside, as shown in Fig. 2. By making the end face of the fire-resistant material 3 visible from the outside when the covering material 4 is installed, it is possible to easily perform a visual inspection to confirm that the fire-resistant material 3 is installed in the compartment penetration part 15. Fig. 2 shows a configuration in which only the end face of the fire-resistant material 3 is visible, but it is also possible to expose a portion of the surface of the fire-resistant material 3 so that not only the end face but also part of the surface is visible.

[0031] The covering material 4 is installed so as to form a gap 70 between it and the fireproof material 3 and the retaining material 5. The gap 70 between the covering material 4 and the fireproof material 3 and the retaining material 5 allows the covering material 4 to be fixed with a margin for axial movement of the insert 21. Since the covering material 4 is fixed to the insert 21 with a margin, even if the insert 21 arranged inside the covering material 4 is moved axially after installation of the covering material 4, the margin of the covering material 4 prevents the fireproof material 3, the covering material 4, and the retaining material 5 from moving together with the insert 21. By preventing the fireproof material 3, the covering material 4, and the retaining material 5 from moving together with the insert 21, it is possible to prevent the fireproof material 3, the covering material 4, and the retaining material 5 from shifting from the compartment penetration 15. In other words, with this configuration, the fireproof material 3, the covering material 4, and the retaining material 5 can be maintained and arranged in appropriate positions in the compartment penetration 15, thereby maintaining the fire resistance of the compartment penetration 15. There are gaps 70 between the covering material 4 and the fireproof material 3 and the retaining material 5, and various configurations can be used to secure the covering material 4 with a margin for axial movement of the penetrating body 21. For example, a configuration in which at least a portion of the covering material 4 is made of a flexible or stretchable material that allows it to bend or curve, or a configuration in which at least a portion of the covering material 4 is secured to the penetrating body 21 with some slack, can be mentioned.

[0032] [Holding material] The retaining material 5 is a member that is disposed in contact with the fireproof material 3 and retains the fireproof material 3. When the fireproof material 3 is in a sheet form, the retaining material 5 may be a sheet-like substrate, as shown in Fig. 1. Then, as shown in Figs. 1 and 2, the fireproof material 3 and the retaining material 5 can be laminated to form a layered structure 30.

[0033] The retaining material 5 is not particularly limited as long as it is a material capable of retaining the fire-resistant material 3, and may be formed, for example, from a metal, a resin material, an inorganic material other than a metal, or a combination of two or more of these. Examples of metallic materials include aluminum, iron, titanium, magnesium, stainless steel, and copper, including simple substances and alloys thereof. Examples of resin materials include polyolefin resins such as polyethylene (PE) and polypropylene (PP), cyclic polyolefin resins, polystyrene resins, acrylonitrile-styrene copolymer (AS) resins, acrylonitrile-butadiene-styrene copolymer (ABS) resins, poly(meth)acrylic resins, polycarbonate resins, polyvinyl alcohol resins, ethylene-vinyl alcohol copolymer (EVOH), saponified ethylene-vinyl ester copolymers, polyester resins such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT), and polyethylene naphthalate (PEN), polyamide resins such as various nylons (Ny), polyurethane resins, acetal resins, cellulose resins, and polyvinylidene chloride resins (PVDC). Examples of inorganic materials include glass and carbon materials.

[0034] Furthermore, the holding material 5 is preferably made of a non-combustible material. Examples of non-combustible materials include metal foil such as aluminum foil, glass cloth, and a metal foil composite that is a composite of metal foil and glass cloth such as aluminum glass cloth.

[0035] As shown in Fig. 2, the laminated structure 30 in which the fire-resistant material 3 and the retaining material 5 are laminated is preferably arranged such that the fire-resistant material 3 is on the partition 11 side and the retaining material 5 is on the opposite side from the partition 11 side. With this configuration, when a fire breaks out and the fire-resistant material 3 expands, the fire-resistant material 3 can expand into the compartment penetration part 15 while being held by the retaining material 5. Therefore, the fire-resistant material 3 can expand while blocking the compartment penetration part 15, resulting in good fire resistance. However, the retaining material 5 may be disposed on the partition portion 11 side, and the fireproof material 3 on the opposite side.

[0036] Furthermore, the laminated structure 30 in which the fireproof material 3 and the retaining material 5 are laminated may be a structure in which either one is laminated multiple times, or may be a structure in which both have multiple layers. For example, as shown in FIGS. 3(a) to 3(e), the laminated structure 30 may be a structure in which at least three layers of the fireproof material 3 and the retaining material 5 are alternately laminated. Specifically, as shown in FIG. 3(a), the laminated structure 30 may be a structure in which three layers of retaining materials 5A, 5B and fireproof material 3A are alternately laminated, or as shown in FIG. 3(b), the laminated structure 30 may be a structure in which three layers of retaining materials 5A and fireproof materials 3A, 3B are alternately laminated. The laminated structure 30 is not limited to a three-layer structure, and may be a structure in which four layers of retaining materials 5A, 5B and fireproof materials 3A, 3B are alternately laminated, as shown in FIG. 3(c). Furthermore, as long as the laminated structure 30 has the order of retaining material 5 / fireproof material 3 / retaining material 5 or the order of fireproof material 3 / retaining material 5 / fireproof material 3, the retaining material 5 and the fireproof material 3 do not need to be alternately arranged one layer at a time, and the same type of layers may be continuously laminated, such as retaining material 5 / retaining material 5 or fireproof material 3 / fireproof material 3. For example, as shown in FIG. 3(d), retaining materials 5A and 5B may be continuously laminated, and fireproof materials 3B, 3C and fireproof material 3A may be alternately laminated. Furthermore, as shown in FIG. 3(e), the laminated structure 30 is not limited in the number of layers, and multiple retaining materials 5A,...5Y, 5Z and multiple fireproof materials 3A,...3Y, 3Z may be alternately laminated in multiple layers. The laminated structure 30 has at least three layers of fireproof materials 3 and retaining materials 5. When the laminated structure 30 is heated, the fireproof materials 3 are properly supported by the retaining materials 5, allowing heat to be evenly distributed. The fireproof materials 3 expand approximately uniformly, improving fire resistance. Furthermore, the approximately uniform expansion of the fireproof materials 3 in the laminated structure 30 allows them to maintain their proper positions and not shift, thereby providing stable fire resistance. Furthermore, when multiple fireproof materials 3 are stacked in the laminated structure 30, the expanded fireproof materials 3 on the partition 11 side are embedded within the gaps 13E, preventing them from moving away from the partition 11 as the laminated structure 30 expands, making it less likely to shift. Meanwhile, the fireproof materials 3 located away from the partition 11 expand evenly as described above, and the resulting expansion residue can appropriately prevent the spread of fire.

[0037] As described above, the retaining material 5 is preferably a sheet capable of retaining the fireproof material 3, and preferably has mechanical strength and a certain degree of flexibility so that it can be easily deformed. The thickness of the retaining material 5 is not particularly limited, but is, for example, 1 to 50 mm, and preferably 5 to 30 mm.

[0038] (Thermal Expandable Resin Composition) The thermally expandable resin composition used in the fire-resistant material such as the fire-resistant material layer will be described in more detail below. The thermally expandable resin composition contains a resin component and a thermally expandable material. When the thermally expandable member is formed from the thermally expandable resin composition containing the resin component, the fire-resistant material 3, the covering material 4, and the retaining material 5 can be easily bent or deformed. Examples of thermally expandable materials include foaming agents that expand upon heating, thermally expandable layered inorganic materials such as vermiculite and thermally expandable graphite, with thermally expandable graphite being preferred. The use of thermally expandable graphite allows for appropriate expansion by the heat of a fire, and the mechanical strength of the expansion residue after expansion is excellent, making it easier to improve fire resistance. The thermally expandable material referred to here does not substantially expand upon molding, etc., as described below, and the thermally expandable resin composition maintains its thermal expandability in the fire-resistant material.

[0039] The expansion start temperature of the thermally expandable material is not particularly limited, but is preferably 150 to 350°C, more preferably 170 to 300°C, and even more preferably 180 to 280°C. By setting the temperature at or below these lower limits, the thermally expandable material is prevented from accidentally expanding due to heating other than that caused by a fire. Furthermore, by setting the temperature at or below the upper limits, the thermally expandable material is more likely to expand reliably due to heating caused by a fire. The expansion starting temperature of a thermally expandable material can be measured by heating a predetermined amount (e.g., 100 mg) of the material at a constant heating rate (e.g., 10°C / min) and measuring the temperature at which the normal force rises. Any measuring device can be used as long as it is capable of controlling the measurement temperature and measuring the normal stress, and a rheometer, for example, can be used. The expansion ratio of the thermally expandable member is preferably 3 times or more, and more preferably 10 times or more. The upper limit of the expansion ratio is not particularly limited, but is, for example, 70 times, and preferably 50 times. When a sheet-like member has multiple fire-resistant material layers with different expansion ratios laminated thereon, the expansion ratio should be selected within the above range. The expansion ratio can be calculated by supplying the thermally expandable member to an electric furnace, heating it at 600°C for 30 minutes, measuring the thickness of the test piece, and then calculating the thickness by dividing the thickness of the test piece after heating by the thickness of the test piece before heating.

[0040] The thermally expandable resin composition in which the thermally expandable material is thermally expandable graphite will be described in detail below. Examples of the resin component of the thermally expandable resin composition include thermoplastic resins, thermosetting resins, and elastomers. Examples of thermoplastic resins include polyvinyl chloride (PVC), chlorinated polyvinyl chloride resin (CPVC), fluororesin, polyphenylene ether, modified polyphenylene ether, polyphenylene sulfide, polycarbonate, polyetherimide, polyetheretherketone, polyarylate, polyamide, polyamideimide, polybutadiene, polyimide, acrylic resin, polyacetal, polyamide, polyethylene (PE), polypropylene (PP), polyolefins such as ethylene vinyl acetate (EVA), polyesters such as ethylene-propylene-diene copolymer (EPDM), chloroprene (CR), polyethylene terephthalate, and polybutylene terephthalate, polycarbonate, polystyrene (PS), polyphenylene sulfide, acrylonitrile-butadiene-styrene copolymer (ABS), acrylonitrile-styrene-acrylonitrile copolymer (ASA), and acrylonitrile / ethylene-propylene-diene / styrene copolymer (AES). Examples of the curable resin include epoxy resin, phenol resin, melamine resin, urea resin, unsaturated polyester resin, alkyd resin, polyurethane, and thermosetting polyimide.

[0041] Examples of elastomers include natural rubber, silicone rubber, styrene-butadiene rubber, isoprene rubber, butadiene rubber, chloroprene rubber, acrylonitrile-butadiene rubber, nitrile-butadiene rubber, butyl rubber, ethylene-propylene rubber, ethylene-propylene-diene rubber, urethane rubber, silicone rubber, and fluororubber. Other examples include thermoplastic elastomers such as olefin-based thermoplastic elastomers (TPO), styrene-based thermoplastic elastomers (TPS), ester-based thermoplastic elastomers, amide-based thermoplastic elastomers, and vinyl chloride-based thermoplastic elastomers. The resin component of the thermally expandable resin composition may be one type or a combination of two or more types.

[0042] Furthermore, the thermally expandable resin composition is more likely to have adhesiveness when an elastomer is used as a resin component. To facilitate the development of adhesiveness, the elastomer preferably contains a liquid elastomer. The liquid elastomer is an elastomer that is liquid at room temperature and normal pressure.

[0043] The thermally expandable resin composition may contain a plasticizer. A plasticizer is preferably used when the resin component is a thermoplastic resin such as polyvinyl chloride resin. Specific examples of the plasticizer include phthalate ester plasticizers such as di-2-ethylhexyl phthalate (DOP), dibutyl phthalate (DBP), diheptyl phthalate (DHP), and diisodecyl phthalate (DIDP); adipic acid esters such as di-2-ethylhexyl adipate (DOA), diisobutyl adipate (DIBA), and dibutyl adipate (DBA), and fatty acid ester plasticizers such as adipic acid polyester; epoxidized ester plasticizers such as epoxidized soybean oil; trimellitic acid ester plasticizers such as tri-2-ethylhexyl trimellitate (TO™) and triisononyl trimellitate (TINT™); phosphate ester plasticizers such as trimethyl phosphate (TMP) and triethyl phosphate (TEP); and process oils such as mineral oil. One or more plasticizers can be used. When the thermally expandable resin composition contains a plasticizer, the content of the plasticizer in the thermally expandable resin composition is, for example, in the range of 0.3 parts by mass or more and 150 parts by mass or less, and preferably in the range of 10 parts by mass or more and 100 parts by mass or less, per 100 parts by mass of the resin component. When the amount of the plasticizer is equal to or greater than these lower limits, good moldability is likely to be achieved, and when the amount is equal to or less than the upper limits, an appropriate strength is imparted to the molded article.

[0044] The total content of the resin component and the plasticizer is preferably 10% by mass or more and 90% by mass or less, more preferably 25% by mass or more and 80% by mass or less, and even more preferably 40% by mass or more and 70% by mass or less, based on the total amount of the resin composition. By setting the content at or above these lower limits, the moldability of the thermally expandable member can be improved. In addition, flexibility is ensured, making it easy to bend and deform. In addition, by setting the content at or below the upper limits, it becomes possible to blend sufficient amounts of components such as thermally expandable graphite and inorganic filler. The total content of the resin component and the plasticizer means the total content of both the resin component and the plasticizer when both are contained, and means the content of the resin component alone when no plasticizer is contained.

[0045] Thermally expandable graphite is a conventionally known substance, and is produced by treating powder of natural flake graphite, pyrolytic graphite, kish graphite, or the like with an inorganic acid such as concentrated sulfuric acid, nitric acid, or selenic acid, and a strong oxidizing agent such as concentrated nitric acid, perchloric acid, perchlorates, permanganates, dichromates, or hydrogen peroxide to produce a graphite intercalation compound. The produced thermally expandable graphite is a crystalline compound that maintains the layered structure of carbon. The thermally expandable graphite used in the present invention may be thermally expandable graphite obtained by acid treatment and neutralizing it with ammonia, aliphatic lower amines, alkali metal compounds, alkaline earth metal compounds, or the like. Examples of the aliphatic lower amine include monomethylamine, dimethylamine, trimethylamine, ethylamine, propylamine, and butylamine. Examples of the alkali metal compounds and alkaline earth metal compounds include hydroxides, oxides, carbonates, sulfates, and organic acid salts of potassium, sodium, calcium, barium, magnesium, and the like.

[0046] The particle size of the thermally expandable graphite is not particularly limited, but is preferably in the range of 20 to 200 mesh. If the particle size is equal to or greater than the lower limit, the degree of expansion of the graphite tends to increase, resulting in good expandability. On the other hand, if the particle size is equal to or less than the upper limit, good dispersibility when kneaded with a resin is achieved, improving moldability.

[0047] The content of thermally expandable graphite in the thermally expandable resin composition is, for example, 3 parts by mass or more and 300 parts by mass or less, relative to 100 parts by mass of the resin component. When the content of thermally expandable graphite is 3 parts by mass or more, thermal expandability is improved. When the content is 300 parts by mass or less, moldability is improved, and the surface properties, mechanical properties, flexibility, etc. of the sealing member are also improved. From these viewpoints, the content of thermally expandable graphite is preferably in the range of 10 parts by mass or more and 200 parts by mass or less, and more preferably in the range of 15 parts by mass or more and 100 parts by mass or less.

[0048] The thermally expandable resin composition may further contain an inorganic filler. There are no particular limitations on the inorganic filler, as long as it is an inorganic filler that is generally used in thermally expandable resin compositions. Specific examples include silica, diatomaceous earth, alumina, zinc oxide, titanium oxide, calcium oxide, magnesium oxide, iron oxide, tin oxide, antimony oxide, ferrites, calcium hydroxide, magnesium hydroxide, aluminum hydroxide, basic magnesium carbonate, calcium carbonate, magnesium carbonate, zinc carbonate, barium carbonate, dawnnite, hydrotalcite, calcium sulfate, barium sulfate, gypsum fiber, calcium silicate, talc, clay, mycelium, montmorillonite, bentonite, activated clay, seviolite, imogolite, sericite, glass fiber, glass beads, silica balloon, aluminum nitride, aluminum phosphite, boron nitride, silicon nitride, carbon black, graphite, carbon fiber, carbon balloon, charcoal powder, various metal powders, potassium titanate, magnesium sulfate, lead zirconium titanate, aluminum borate, molybdenum sulfide, silicon carbide, stainless steel fiber, zinc borate, various magnetic powders, slag fiber, fly ash, and dewatered sludge. The inorganic filler may be used alone or in combination of two or more. When an inorganic filler is contained, the content of the inorganic filler in the thermally expandable resin composition is preferably in the range of 3 parts by mass or more and 200 parts by mass or less, and more preferably in the range of 10 parts by mass or more and 150 parts by mass or less, per 100 parts by mass of the resin component.

[0049] The thermally expandable resin composition may contain a known tackifier, which makes it easier to impart tackiness to the thermally expandable member. Furthermore, the thermally expandable resin composition used in the present invention may contain, as needed, additives commonly used in thermally expandable resin compositions, such as flame retardants, heat-absorbing agents, heat stabilizers, lubricants, processing aids, antioxidants, antistatic agents, pigments, crosslinking agents, crosslinking accelerators, etc. Among these, it is preferable to use processing aids.

[0050] The thermally expandable member can be manufactured, for example, as follows: First, predetermined amounts of resin components, a thermally expandable material, and other additives, if necessary, are mixed in a mixer such as a kneading roll to obtain a thermally expandable resin composition. The thermally expandable resin composition may be diluted by adding a solvent as appropriate. The thermally expandable resin composition, diluted as necessary, is applied to a support such as a substrate or a release sheet, and then appropriately dried, cured, etc., to form a fire-resistant material layer (thermally expandable member) on one side of the support. Alternatively, the fire-resistant material layer may be formed on one side of the support by a known method such as extrusion molding. The fire-resistant material layer formed on the release sheet may be peeled from the release sheet to form a sheet-like member consisting of a single fire-resistant material layer. After peeling from the release sheet, the sheet-like member may be laminated on another layer to obtain a multilayered sheet-like member. Alternatively, the composition may be laminated on another layer while still laminated on the release sheet or another support.

[0051] The construction method for the compartment penetration structure 10 in this embodiment includes a step of installing the above-described fireproof structure 1 so as to close the gap 13E between the opening 13C of the compartment penetration portion 15 provided in the partition 11 and the insert 21. This step can be performed in a manner in which a laminated structure 30 consisting of a fireproof material 3 and a retaining material 5 is prepared, and the fireproof material 3 in the laminated structure 30 is fixed to the partition 11. After the laminated structure 30 consisting of the fireproof material 3 and the retaining material 5 is fixed to the partition 11, the covering material 4 is fixed to the insert 21 and at least one of the partition 11 and the laminated structure 30. In this way, construction can be performed by fixing the fireproof material 3, covering material 4, and retaining material 5 provided in the fireproof structure 1 to the partition 11 and the insert 21. Therefore, construction is easy.

[0052] According to the configuration of this embodiment, the gap 13E inside the opening 13C of the compartment penetration 15 is closed by the fireproof structure 1 including the fireproof material 3, the covering material 4, and the retaining material 5, and the fireproof material 3 can be appropriately held in the compartment penetration 15 by the covering material 4 and the retaining material 5. Therefore, appropriate fire resistance can be imparted to the compartment penetration treatment structure 10.

[0053] [Modification of the first embodiment] In the fireproof structure 1 shown in Figs. 1 and 2, the retaining material 5 and the fireproof material 3 are shown as an integral laminated structure 30, but they may be separate members.

[0054] In the fire-resistant structure 1 shown in Figures 1 and 2, the covering material 4 is shown as being separate from the laminated structure 30 in which the fire-resistant material 3 and the retaining material 5 are laminated, but it may also be a laminated structure in which the covering material 4 is laminated integrally with the fire-resistant material 3 and the retaining material 5.

[0055] The covering material 4 is not limited to the above configuration, and the covering material 4 may be provided so as to be connected to the laminated structure 30. For example, as shown in FIG. 4 , four covering materials 4 may be used so as to be connected to the four edges of the laminated structure 30, and four extension portions may extend outward from the laminated structure 30. According to this embodiment, by connecting the four extension portions to the laminated structure 30, the covering material 4 can be installed integrally with the fire-resistant material 3 and the retaining material 5. Furthermore, it is not necessary to use four covering materials 4 as described above, and a structure in which one covering material 4 is connected to the laminated structure 30 may be used. Examples of means for connecting the covering material 4 to at least a portion of the laminated structure 30 include fixing by known fixing means such as adhesives, pressure-sensitive adhesives, adhesive tapes, and fixing members such as tackers and screws. Here, the adhesives, pressure-sensitive adhesives, and adhesive tapes are preferably made of non-combustible materials, semi-non-combustible materials, or flame-retardant materials, and it is advisable to blend a flame retardant or the like into the adhesives, pressure-sensitive adhesives, etc.

[0056] 1 and 2, the covering material 4 is shown as a sheet-like member, but as shown in Figures 5 and 6, it may be a covering material 4D made of an elastic foam having flexibility capable of following the outer periphery of the insert 21. Specific examples of elastic foam include olefin-based resin foam and urethane-based resin foam. 6, the covering material 4D is fixed in a state where it is wrapped around the outer peripheral surface of the penetrating body 21 one or more times. The covering material 4D is preferably in close contact with the penetrating body 21, and therefore may be deformed appropriately to fit the shape of the penetrating body 21. Here, the covering material 4D may be fixed to the outer circumferential surface of the penetrating body 21 by an adhesive layer disposed on the inner circumferential side. Alternatively, the covering material 4D may be fixed to the penetrating body 21 by a separately provided fixing member. Examples of such fixing members include a string-like member wound around the outer circumferential side of the covering material 4D, or adhesive tape. Alternatively, the covering material 4D5 may be fixed to the penetrating body 21 by a combination of two or more of these. The thickness of the covering material 4D is not particularly limited, but is, for example, 0.1 to 10 mm, and preferably 0.15 to 5 mm. When the covering material 4D has a thickness equal to or less than these upper limits, flexibility is imparted, and the covering material 4D can be wrapped tightly around the outer periphery of the penetrating body 21. When the covering material 4D has a thickness equal to or greater than the lower limits, the covering material 4D can be easily disposed.

[0057] [Second embodiment] Next, a second embodiment of the present invention will be described in detail. The second embodiment differs from the first embodiment in that, as shown in Figures 7 and 8, the compartment penetration treatment material 1 has a configuration including a fire-resistant material 3, a cladding material 4, and a position control material 6. Below, the differences between the second embodiment and the first embodiment will be described. Furthermore, parts whose description is omitted are the same as those in the first embodiment. Furthermore, in the following description, members having the same configuration as those in the first embodiment will be given the same reference numerals.

[0058] The compartment penetration structure 10 in this embodiment is configured to have a position control material 6, which allows the use of an irregular material such as putty as the fire-resistant material 3. The fire-resistant material 3 of the irregular material is fixed by being arranged so as to be in contact with the position control material 6. In addition, as shown in FIG. 8, the fire-resistant material 3 of the irregular material may be arranged so as to be in contact with the position control material 6, and may be fixed by being covered and restricted by a covering material 4.

[0059] The fire-resistant material 3 of the irregular member is preferably a thermally expandable member that expands when heated, as in the first embodiment. The thermally expandable member prevents the spread of fire by expanding in the event of a fire. The thermally expandable member is preferably formed from the thermally expandable resin composition described above. In order to make the thermally expandable resin composition into an irregular putty, the type and amount of resin, the amount of thermally expandable graphite, the type and amount of inorganic filler, etc. may be appropriately adjusted.

[0060] [Position control material] The position control material 6 is a member that is placed in the partition 11 and controls the position of the fire-resistant material 3, thereby preventing the fire-resistant material 3 from excessively penetrating into the partition 11 through the opening 13C. By providing the compartment penetration treatment material 1 with the position control material 6, even when an amorphous fire-resistant material 3 is used, it is possible to prevent the fire-resistant material 3 from excessively penetrating into the partition 11 through the opening 13C. The position control material 6 is fixed to the partition 11. The means for fixing the position control material 6 to the partition portion 11 may be, for example, a known fixing means such as an adhesive, a pressure-sensitive adhesive, an adhesive tape, or a fixing member such as a tacker or a screw. Here, the adhesive, the pressure-sensitive adhesive, and the adhesive tape are preferably made of a non-combustible material, a semi-non-combustible material, or a flame-retardant material, and it is advisable to blend a flame retardant or the like into the adhesive, the pressure-sensitive adhesive, or the like.

[0061] As shown in FIGS. 4 and 5, the position control material 6 is preferably in a sheet form. The sheet-like position control material 6 has slits 60 through which the inserting body 21 is inserted, and at least one of the slits 60 extends to the outer edge of the sheet-like position control material 6. The slits 60 are formed by cutting. The sheet-like position control material 6 allows the inserting body 21 to be inserted into the sheet-like position control material 6 through the slits 60 extending to the outer edge. Note that the slits 60 may have a form having a hole through which the inserting body 21 is inserted and a slit 60 extending from the hole to the outer edge of the sheet-like position control material 6.

[0062] The position control material 6 is not particularly limited as long as it is a material that can control the position of the fire-resistant material 3, and is formed, for example, from a metal, a resin material, an inorganic material other than a metal, or a combination of two or more of these. The position control member 6 is preferably made of a non-combustible material. Examples of non-combustible materials include metal sheets such as metal plates, metal foils such as aluminum foils, glass cloths, and metal foil composites that are composites of metal foils and glass cloths such as aluminum glass cloths, among which metal sheets are preferred.

[0063] As described above, the position control material 6 is preferably capable of controlling the position of the refractory material 3, has mechanical strength, and is preferably given a certain degree of flexibility so as to be easily deformed. The thickness of the position control material 6 is not particularly limited, but is, for example, 1 to 50 mm, and preferably 5 to 30 mm.

[0064] The construction method for the compartment penetration structure 10 in this embodiment includes a step of installing the above-described fireproof structure 1 so as to close the gap 13E between the opening 13C of the compartment penetration portion 15 provided in the partition portion 11 and the insert 21. In this step, the position control material 6 may be fixed to the partition portion 11, and then the fireproof material 3 may be arranged so as to be in contact with the fixed position control material 6, or the position control material 6 on which the fireproof material 3 is arranged may be fixed to the partition portion 11. The covering material 4 may be fixed to the partition portion 11 and the insert 21 after the position control material 6 and the fireproof material 3 are arranged. Furthermore, the covering material 4 may be partially fixed (for example, to the insert 21 or the position control material 6) and then fixed to the partition portion 11 and the insert 21 before the position control material 6 is fixed to the partition portion 11 or before the fireproof material 3 is arranged on the position control material 6. As a result, the refractory material 3 is fixed by being restricted by the covering material 4 and the position control material 6. In addition, in Figure 8, the covering material 4 is shown fixed to the insert 21 and the position control material 6, but it may be fixed to the partition portion 11 instead of the position control material 6, or it may be fixed to the partition portion 11 together with the position control material 6. In this way, the fireproof material 3, the covering material 4, and the position control material 6 included in the fireproof structure 1 can be installed by fixing them to the partition portion 11 and the insert 21. Therefore, the installation is easy.

[0065] According to the configuration of this embodiment described above, the gap 13E inside the opening 13C of the compartment penetration 15 is blocked by the fireproof structure 1 including the fireproof material 3, the covering material 4, and the position control material 6, and the fireproof material 3 can be appropriately held in the compartment penetration 15 by the covering material 4 and the position control material 6. Therefore, appropriate fire resistance can be imparted to the compartment penetration treatment structure 10.

[0066] [Modification of the second embodiment] In the fireproof structure 1 shown in Figures 7 and 8, the covering material 4 is in a sheet form, but the covering material 4 is not limited to a sheet form. For example, as shown in Figures 9 and 10, a covering material 4A may be used, which has a top surface 43 with a hole 43A and a sleeve-shaped side surface 44. The hole 43A provided in the top surface 43 is for inserting the penetrating body 21 and may be circular, but may have any shape other than circular depending on the shape of the penetrating body 21. The side surface 44 of the covering material 4A has a certain height so that the filler material 3 can be contained inside the covering material 4A.

[0067] The covering material 4A is not particularly limited as long as it is a material that can accommodate the filler 3 inside, and may be formed, for example, from a metal, a resin material, an inorganic material other than a metal, or a combination of two or more of these. A specific example of the covering material 4A is a metal frame. The covering material 4A may be an integrated type, or may be a combination of two or more divided pieces. The integrated covering material 4A has a slit (not shown) extending from the hole 43A toward the outer circumferential surface, and the slit is formed across the top surface 43 and the side surface 44. The covering material 4A has a slit, which allows the penetrating body 21 to be inserted into the hole 43A through the slit. Furthermore, in the covering material 4A formed by combining two or more divided pieces, the penetrating body 21 can be inserted into the hole 43A by placing the separated pieces at positions corresponding to the hole 43A and then combining the pieces. The covering material 4A may be a sleeve having only a side surface 44 without a top surface 43, as long as the inserting body 21 can be inserted therein.

[0068] [Third embodiment] Next, a third embodiment of the present invention will be described in detail. The third embodiment differs from the second embodiment in that, as shown in Figures 11 and 12, the compartment penetration treatment material 1 has a configuration including a fire-resistant material 3, a cladding material 4, a retaining material 5A, and a position control material 6. Below, the differences between the second embodiment and the third embodiment will be described. Furthermore, parts whose description is omitted are the same as those in the second embodiment. Furthermore, in the following description, members having the same configuration as those in the first and second embodiments will be assigned the same reference numerals.

[0069] The compartment penetration structure 10 in this embodiment has a configuration including the retaining material 5A and the position control material 6, and therefore it is possible to use an amorphous material such as putty as the fireproof material 3.

[0070] The fireproof material 3 in this embodiment can maintain its shape by being covered with the retaining material 5A. When the fireproof material 3 and the retaining material 5A are flexible, they can be deformed appropriately, for example, so as to fit along the outer periphery of the insert 21, and can be arranged without gaps. The retaining material 5A is not particularly limited as long as it is a material that can contain the fire-resistant material 3 inside and maintain the shape of the fire-resistant material 3, and is preferably formed from, for example, a metal, a resin material, or the like, and is a resin film from the viewpoint of flexibility and ease of handling. By employing a bag-shaped resin film as the retaining material 5A, the fire-resistant material 3 can be contained inside, and a bag-shaped resin film is particularly preferable when the fire-resistant material 3 is an irregular member.

[0071] The construction method for the compartment penetration structure 10 in this embodiment includes a step of installing the above-described fireproof structure 1 so as to close the gap 13E between the opening 13C of the compartment penetration portion 15 provided in the partition 11 and the insert 21. In this step, the position control material 6 is fixed to the partition 11, and then the fireproof material 3 covered with the retaining material 5A is placed on the fixed position control material 6. The fireproof material 3 covered with the retaining material 5A is deformed to fit the outer periphery of the insert 21, and arranged without any gaps. The covering material 4 may be fixed to the partition 11 and the insert 21 after the position control material 6 and the fireproof material 3 covered with the retaining material 5A are arranged. Alternatively, the covering material 4 may be partially fixed (e.g., to the insert 21 or the position control material 6) before the position control material 6 is fixed to the partition 11 or before the fireproof material 3 is arranged on the position control material 6, and then fixed to the partition 11 and the insert 21. As a result, the refractory material 3 covered with the holding material 5A is regulated by the covering material 4 and the position control material 6 and is fixed. In addition, in Figure 12, the covering material 4 is shown fixed to the insert 21 and the position control material 6, but it may be fixed to the partition portion 11 instead of the position control material 6, or it may be fixed to the partition portion 11 together with the position control material 6. In this way, the fireproof material 3, the covering material 4, and the position control material 6 covered with the retaining material 5A of the fireproof structure 1 can be installed by fixing them to the partition portion 11 and the insert 21. Therefore, the installation is easy.

[0072] According to the configuration of this embodiment, the gap 13E inside the opening 13C of the compartment penetration 15 is closed by the fireproof structure 1 including the fireproof material 3, the covering material 4, the retaining material 5A, and the position control material 6, and the fireproof material 3 can be appropriately held in the compartment penetration 15 by the covering material 4, the retaining material 5A, and the position control material 6. Therefore, appropriate fire resistance can be imparted to the compartment penetration treatment structure 10.

[0073] [Modification of the third embodiment] 11 and 12 show an embodiment in which the covering material 4 is in a thin sheet shape, but the covering material 4 is not limited to a thin sheet shape. For example, a thick sheet-shaped covering material 4B as shown in FIGS. 13 and 14 may be used.

[0074] The thick sheet-like covering material 4B can have a laminated structure in which a fire-resistant material layer is laminated on a sheet-like substrate. The laminated covering material 4B has less flexibility than the thin covering material 4, but has excellent fire resistance. The thickness of the thick sheet-like covering material 4B is not particularly limited, but is, for example, 2 to 20 mm, and preferably 1 to 15 mm.

[0075] The covering material 4B may have an adhesive fire-resistant material layer or an adhesive layer. The adhesive fire-resistant material layer and the adhesive layer may form the outermost layer of the covering material 4B. With the above configuration, the covering material 4B can be fixed to at least one of the holding material 5A and the position control material 6 without using a fixing member separate from the covering material 4B. When the covering material 4B has an adhesive fireproof material layer or adhesive layer on its outermost layer, a release sheet may be attached to the outermost layer. The release sheet may be peeled off from the outermost layer when in use.

[0076] 14, the covering material 4B is provided in contact with the retaining material 5A so as to indirectly cover a portion of the fireproof material 3, and is adhered and fixed to the surface of the retaining material 5A. Means for adhering and fixing the covering material 4B and the retaining material 5A may be an adhesive, an adhesive tape, or the like, or may be a means using an adhesive fireproof material layer or adhesive layer arranged on the inside.

[0077] The covering material 4B preferably covers a portion of the fire-resistant material 3 held by the holding material 5A, making the portion of the fire-resistant material 3 invisible from the outside. Specifically, it is preferable that the covering material 4B covers the portion of the fire-resistant material 3 through which the insert 21 has been inserted, thereby improving the design of the compartment penetration part 15 and the fire resistance performance of the compartment penetration part 15. On the other hand, the covering material 4B may cover a portion of the fire-resistant material 3 held by the holding material 5A so that it is visible from the outside. Specifically, as shown in Fig. 14, the covering material 4 may make a portion of the fire-resistant material 3 held by the holding material 5A visible from the outside. With the covering material 4B installed, making a portion of the fire-resistant material 3 held by the holding material 5A visible from the outside facilitates visual inspection of whether the fire-resistant material 3 is installed in the compartment penetration part 15.

[0078] [Fourth embodiment] Next, a fourth embodiment of the present invention will be described in detail. The fourth embodiment differs from the first to third embodiments in that, as shown in Figs. 15 and 16, the compartment penetration treatment material 1 has a fire-resistant material 3, a cladding material 4B, and a retaining material 5A. Below, the differences between the fourth embodiment and the first to third embodiments will be described. Furthermore, parts whose description will be omitted are the same as those of the first to third embodiments. Furthermore, in the following description, members having the same configuration as those of the first to third embodiments will be assigned the same reference numerals.

[0079] In this embodiment, the fire-resistant material 3 can maintain its shape by being covered with the retaining material 5A. Furthermore, since the position of the fire-resistant material 3 in the compartment penetration part 15 can be controlled by being covered with the retaining material 5A, the retaining material 5A also functions as the position control material 6. When the fire-resistant material 3 and the retaining material 5A are flexible, they can be deformed appropriately, for example, so as to fit along the outer periphery of the insert 21, allowing them to be arranged without gaps. The retaining material 5A is not particularly limited as long as it is a material that can contain the fire-resistant material 3 inside and maintain the shape of the fire-resistant material 3, and is preferably formed from, for example, a metal, a resin material, or the like, and is a resin film from the viewpoint of flexibility and ease of handling. By employing a bag-shaped resin film as the retaining material 5A, the fire-resistant material 3 can be contained inside, and a bag-shaped resin film is particularly preferable when the fire-resistant material 3 is an irregular member.

[0080] The holding material 5A may have an adhesive fireproof material layer or an adhesive layer. The adhesive fireproof material layer and the adhesive layer may form the outermost layer of the holding material 5A. With the above configuration, the holding material 5A can be fixed to at least one of the partitioning portion 11 and the covering material 4B without using a fixing member separate from the holding material 5A. When the holding material 5A has an adhesive fireproof material layer or adhesive layer on its outermost layer, a release sheet may be attached to the outermost layer. The release sheet may be peeled off from the outermost layer when in use.

[0081] 16, the covering material 4B is provided in contact with the retaining material 5A so as to indirectly cover a portion of the fire-resistant material 3, and is adhered and fixed to the surface of the retaining material 5A. Means for adhering and fixing the covering material 4B and the retaining material 5A may be an adhesive, an adhesive tape, or the like, or may be a means using an adhesive fire-resistant material layer or adhesive layer arranged on the inside.

[0082] The covering material 4B preferably covers a portion of the fire-resistant material 3 held by the holding material 5A, making the portion of the fire-resistant material 3 invisible from the outside. Specifically, it is preferable that the covering material 4B covers the portion of the fire-resistant material 3 through which the insert 21 has been inserted, thereby improving the design of the compartment penetration part 15 and the fire resistance performance of the compartment penetration part 15. On the other hand, the covering material 4B may cover a portion of the surface of the fire-resistant material 3 held by the holding material 5A so that it is visible from the outside. Specifically, as shown in Fig. 16, the covering material 4B may make a portion of the fire-resistant material 3 held by the holding material 5A visible from the outside. By making a portion of the fire-resistant material 3 held by the holding material 5A visible from the outside with the covering material 4B installed, it is possible to easily perform a visual inspection to confirm that the fire-resistant material 3 is installed in the compartment penetration part 15.

[0083] The construction method for the compartment penetration structure 10 in this embodiment includes a step of installing the above-described fireproof structure 1 so as to close the gap 13E between the opening 13C of the compartment penetration portion 15 provided in the partition 11 and the insert 21. In this step, the fireproof material 3 covered with the retaining material 5A is placed, and the fireproof material 3 covered with the retaining material 5A is deformed to fit the outer periphery of the insert 21, so as to be placed without any gaps. The covering material 4B can be fixed to the retaining material 5A after the fireproof material 3 covered with the retaining material 5A is placed. In this way, the fireproof material 3, the covering material 4B, and the retaining material 5A included in the fireproof structure 1 can be installed by fixing them to the partition 11 and the insert 21. This makes the construction easy.

[0084] According to the configuration of this embodiment, the gap 13E inside the opening 13C of the compartment penetration 15 is closed by the fireproof structure 1 including the fireproof material 3, the covering material 4, and the retaining material 5A, and the fireproof material 3 can be appropriately held in the compartment penetration 15 by the covering material 4 and the retaining material 5A. Therefore, appropriate fire resistance can be imparted to the compartment penetration treatment structure 10.

[0085] [Modification of the fourth embodiment] In the fireproof structure 1 shown in Figures 15 and 16, the covering material 4 is in a sheet form, but the covering material 4 is not limited to a sheet form. For example, as shown in Figures 17 and 18, a covering material 4A may be used, which has a top surface 43 with a hole 43A and a sleeve-shaped side surface 44. The hole 43A provided in the top surface 43 is for inserting the penetrating body 21 and may be circular, but may have any shape other than circular depending on the shape of the penetrating body 21. The side surface 44 of the covering material 4A has a certain height so that the filler material 3 can be contained inside the covering material 4A.

[0086] The covering material 4A is not particularly limited as long as it is a material that can accommodate the filler 3 inside, and may be formed, for example, from a metal, a resin material, an inorganic material other than a metal, or a combination of two or more of these. A specific example of the covering material 4A is a metal frame. The covering material 4A may be an integrated type, or may be a combination of two or more divided pieces. The integrated covering material 4A has a slit (not shown) extending from the hole 43A toward the outer circumferential surface, and the slit is formed across the top surface 43 and the side surface 44. The covering material 4A has a slit, which allows the penetrating body 21 to be inserted into the hole 43A through the slit. Furthermore, in the covering material 4A formed by combining two or more divided pieces, the penetrating body 21 can be inserted into the hole 43A by placing the separated pieces at positions corresponding to the hole 43A and then combining the pieces. The covering material 4A may be a sleeve having only a side surface 44 without a top surface 43, as long as the inserting body 21 can be inserted therein.

[0087] [Fifth embodiment] Next, a fifth embodiment of the present invention will be described in detail. The fifth embodiment differs from the first to fourth embodiments in that, as shown in Figs. 19 and 20, the compartment penetration treatment material 1 has a fire-resistant material 3, a cladding material 4C, and a position control material 6A. Below, the differences between the fifth embodiment and the first to fourth embodiments will be described. Furthermore, parts whose description will be omitted are the same as those of the first to fourth embodiments. Furthermore, in the following description, members having the same configuration as those of the first to fourth embodiments will be given the same reference numerals.

[0088] The compartment penetration structure 10 in this embodiment has a configuration including the covering material 4C, and therefore, it is possible to use an amorphous material such as putty as the fireproof material 3.

[0089] The fire-resistant material 3 in this embodiment can maintain its shape by being covered with the covering material 4C. That is, the covering material 4C in this embodiment also functions as the retaining material 5. When the fire-resistant material 3 and the covering material 4C are flexible, they can be deformed appropriately, for example, so as to fit the outer periphery of the insert 21 and can be arranged without gaps. The covering material 4C is not particularly limited as long as it is a material that can contain the fire-resistant material 3 and maintain the shape of the fire-resistant material 3, and is preferably formed from, for example, a metal, a resin material, or the like, and is a resin film from the viewpoint of flexibility and ease of handling. By employing a bag-shaped resin film as the covering material 4C, the fire-resistant material 3 can be contained therein, and a bag-shaped resin film is particularly preferable when the fire-resistant material 3 is an irregular member.

[0090] The covering material 4C may have an adhesive fire-resistant material layer or an adhesive layer. The adhesive fire-resistant material layer and the adhesive layer may constitute the outermost layer of the covering material 4C. With the above configuration, the covering material 4C can be fixed to the position control material 6A without using a fixing member separate from the covering material 4C. When the covering material 4C has an adhesive fire-resistant material layer or an adhesive layer on its outermost layer, a release sheet may be attached to the outermost layer. The release sheet may be peeled off from the outermost layer when the covering material 4C is used.

[0091] The position control material 6A is a sheet-like member, and as shown in FIG. 20, the portion that controls the position of the fire-resistant material 3 surrounds the insert 21 so as to be in contact with it, and is fixed to the insert 21 by a string-like member 23 wound around it from the outside. The string-like member 23 may be any bendable member, and is preferably a wire member including a wire. The wire member may be a metal wire alone, or a resin-coated wire such as Nejirikko (registered trademark) in which a metal wire is coated with resin, or a wire and fiber entangled member such as a maul. When a wire member is used, the covering material 4 can be fixed to the insert 21 simply by twisting it. In another embodiment (not shown), the position control material 6A has a portion that controls the position of the fire-resistant material 3, which surrounds the insert 21 so as to be in contact with the insert 21 and is fixed to the insert 21 by an adhesive tape wrapped around it from the outside. The adhesive tape preferably has a substrate and an adhesive layer provided on one side of the substrate. The substrate may be made of paper, resin film, cloth, or any of the non-combustible materials described above. The adhesive layer may be made of, for example, an acrylic adhesive, a urethane adhesive, a rubber adhesive, or a silicone resin adhesive. The adhesive may also contain a known flame retardant.

[0092] The position control member 6A is preferably a deformable sheet, and is preferably flexible and easily deformable, so as to facilitate fixing to the inserting body 21. The thickness of the position control member 6A is not particularly limited, but is, for example, 0.1 to 5 mm, and preferably 0.5 to 3 mm.

[0093] The position control material 6A preferably covers a part of the surface of the fire-resistant material 3 held by the covering material 4C, making a part of the fire-resistant material 3 invisible from the outside. Specifically, it is preferable that the position control material 6A covers the part of the fire-resistant material 3 through which the insert 21 is inserted, thereby improving the design of the compartment penetration part 15 and the fire resistance performance of the compartment penetration part 15. On the other hand, the position control material 6A may be arranged so that a portion of the surface of the fire-resistant material 3 covered with the covering material 4C is visible from the outside. Specifically, as shown in Fig. 17, the position control material 6A may be arranged so that a portion of the surface of the fire-resistant material 3 covered with the covering material 4C is visible from the outside. With the position control material 6A installed, making a portion of the surface of the fire-resistant material 3 covered with the covering material 4C visible from the outside facilitates visual inspection of whether the fire-resistant material 3 is installed in the compartment penetration part 15.

[0094] The construction method for the compartment penetration structure 10 in this embodiment includes a step of installing the above-described fireproof structure 1 so as to close the gap 13E between the opening 13C of the compartment penetration portion 15 provided in the partition portion 11 and the insert 21. In this step, first, the position-controlling member 6A is fixed to the insert 21, and the fixed position-controlling member 6A is moved near the opening 13C of the compartment penetration portion 15. Thereafter, the fireproof material 3 covered with the covering material 4C is arranged so as to contact the position-controlling member 6A and the insert 21, and the fireproof material 3 covered with the covering material 4C is deformed to fit along the outer periphery of the insert 21, so as to be arranged without any gaps. Then, after the fireproof material 3 covered with the covering material 4C is arranged, the end of the position-controlling member 6A can be fixed so as to fit along the outer periphery of the covering material 4C. In this way, the fireproof material 3, the covering material 4C, and the position control material 6A included in the fireproof structure 1 can be installed by fixing them to the partition portion 11 and the insert 21. Therefore, the installation is easy.

[0095] According to the configuration of this embodiment, the gap 13E inside the opening 13C of the compartment penetration 15 is blocked by the fireproof structure 1 including the fireproof material 3, the covering material 4, the retaining material 5A, and the position control material 6, and the fireproof material 3 can be appropriately held in the compartment penetration 15 by the covering material 4C and the position control material 6A. Therefore, appropriate fire resistance can be imparted to the compartment penetration treatment structure 10.

[0096] [Other embodiments] The present invention is not limited to the configurations of the above-described first to fifth embodiments, and any improvements and modifications may be made without departing from the technical spirit of the present invention. For example, in each of the above embodiments, the compartment penetration treatment material may have a member that is connected to a part of the fire-resistant structure 1 and placed inside the compartment penetration part 15. Examples of such members include fire-resistant materials and accessories. As a specific example, a modified example of the second embodiment is shown in Fig. 21. As the fire-resistant material, for example, a block-shaped additional fire-resistant material 80 as shown in Fig. 21 is used, and the block-shaped additional fire-resistant material 80 is preferably connected to the position-controlling material 6 that is part of the fire-resistant structure 1. The manner of connection is not particularly limited, but for example, the additional fire-resistant material 80 may be laminated on one surface of the position-controlling material 6 or may be connected to an end surface of the position-controlling material 6. As described above, the additional fire-resistant material 80 is preferably made of a thermally expandable material that expands when heated, and in particular, it is preferably made of a thermally expandable resin composition.

[0097] Furthermore, in the above description, the partition 11 is a hollow wall having a hollow portion 13 therein, but it is not limited to a hollow wall and may be a wall without a hollow, for example, made of a single wall material. Furthermore, the partition 11 is not limited to a wall of a building and may be a ceiling or floor of a building. Even if the partition is a ceiling or floor, it may have a structure with a hollow portion between two partition materials, or a structure without a hollow portion, for example, made of a single partition material.

[0098] Furthermore, in each of the above embodiments, it has been explained on the assumption that compartment penetration treatment materials of the same structure are provided in both openings 13C, 13D of partition 11 (i.e., on both sides of partition 11), but compartment penetration treatment structures of different structures may be provided in each opening 13C, 13D. For example, one opening 13C may be provided with a compartment penetration treatment structure according to the first embodiment, and the other opening 13D may be provided with a compartment penetration treatment structure according to the second embodiment. Furthermore, the compartment penetration treatment material in opening 13D may be omitted. [Explanation of symbols]
