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 buildings, 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 designed with fire prevention measures (fireproof 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] Known methods for making compartment penetrations fireproof include filling the gap between the long insert and the penetration hole with fireproof putty or a fireproof pack containing fireproof putty inside a bag. When using an irregular filler, a tubular member made of fireproof material may also be placed inside the penetration hole of each wall section and between 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 fillers are used to treat compartment penetrations, there is variation among workers, and sufficient fire protection performance may not be achieved. Furthermore, when installing fire-resistant 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 fire-resistant materials have been installed according to regulations, it is necessary to destroy the compartment penetration structure and examine 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 pipes are inserted, if the insert is moved after the compartment penetration structure is applied, the fire-resistant materials installed inside may be displaced from their original positions. External forces such as earthquakes may also cause the fire-resistant materials to be displaced from their original positions. Such displacement of the fire-resistant materials from their original positions makes it difficult for the compartment penetration to achieve the fire-resistant performance desired for its fire-resistant structure.

[0008] Therefore, the present invention aims to provide a compartment penetration treatment structure, a construction method for a compartment penetration treatment structure, and a compartment penetration treatment material that reduces variation in fire resistance performance and allows easy confirmation that the compartment penetration treatment material is installed as specified.

[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, as shown in FIG. 1, which is formed in a partition 11 of a building and has a compartment penetration section 15, through which a long penetrating body 21 is inserted, as a fireproof structure. The compartment penetration member used in the compartment penetration structure according to the first embodiment of the present invention includes a sheet-like member 3 and a cover member 5.

[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 components that are installed in the compartment penetration section 15 to form the compartment penetration processing structure 10 (in this embodiment, the sheet-like member 3, the cover member 5, and the fixing members for fixing these, etc.) are sometimes collectively referred to as compartment penetration processing materials. In addition, the following describes the configuration of the compartment penetration processing structure on one opening 13C side of the partition section 13, 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 treatment structure 10 of the first embodiment comprises a sheet-like member 3 and a cover member 5 as compartment penetration treatment materials, and at least one of the sheet-like member 3 and the cover member 5 has a fire-resistant material as described below.

[0017] [Sheet-like member] As shown in FIG. 1 , the sheet-shaped member 3 has slits 30 through which the inserting body 21 is inserted, and at least one of the slits 30 extends to the outer edge of the sheet-shaped member 3. The slits 30 are formed by cutting. The inserting body 21 can be inserted into the sheet-shaped member 3 through the slits 30 extending to the outer edge of the sheet-shaped member 3. Note that the slits 30 may have a form including a hole through which the inserting body 21 is inserted and a slit 30 extending from the hole to the outer edge of the sheet-shaped member 3. 2, the sheet-like member 3 with the inserter 21 inserted through the slit 30 is placed on the outer surface 11A from the outside of the partition 11 so as to cover the gap 13E between the opening 13C and the inserter 21, thereby closing the gap 13E between the opening 13C and the inserter 21 with the sheet-like member 3. The sheet-like member 3 is placed so as to be in contact with both the outer surface 11A of the partition 11 and the outer periphery of the inserter 21.

[0018] The sheet-like member 3 may be fixed to the outer surface 11A of the partition section 11 by an adhesive layer or a fire-resistant material layer provided on the sheet-like member 3, or may be fixed to the outer surface 11A of the partition section 11 by a fixing member such as a tacker or a screw that is separate from the sheet-like member 3. Of course, the sheet-like member 3 may be fixed to the partition section 11 by a combination of two or more of these methods.

[0019] The sheet-like member 3 is preferably placed so as to be in contact with the insert 21 and the partition 11. By placing the sheet-like member 3 so as to be in contact with the insert 21 and the partition 11, the opening 13C of the partition 11 can be blocked, and fire resistance can be improved.

[0020] The sheet-shaped member 3 has at least one of a fire-resistant material layer and a non-combustible material layer. Similarly, the cover member 5 has at least one of a fire-resistant material layer and a non-combustible material layer. However, either the sheet-shaped member 3 or the cover member 5 has a fire-resistant material layer (fire-resistant material). This allows the compartment penetration structure 10 to ensure fire resistance. Furthermore, from the viewpoint of ensuring fire resistance, it is preferable that at least the sheet-shaped member 3 has a fire-resistant material layer, and more preferably, the sheet-shaped member 3 has a fire-resistant material layer and the cover member 5 has a non-combustible material layer.

[0021] The fire-resistant material layer used in the sheet-shaped member 3 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 10 mm, and preferably 0.5 to 5 mm. When the fire-resistant material layer has a thickness equal to or less than these upper limit values, flexibility is imparted to the sheet-shaped member 3. When the fire-resistant material layer has a thickness equal to or greater than the lower limit values, fire resistance is more easily ensured.

[0022] The sheet-shaped member 3 may be composed of a single layer of fire-resistant material, a single layer of non-combustible material, or both a fire-resistant layer and a non-combustible material layer. The sheet-shaped member 3 may also have layers other than the fire-resistant layer and the non-combustible material layer, such as a substrate and an adhesive layer.

[0023] The sheet-shaped member 3 may have, for example, an adhesive fire-resistant material layer or an adhesive layer. The adhesive fire-resistant material layer and the adhesive layer may form the outermost surface of the sheet-shaped member 3. With the above-described configuration, the sheet-shaped member 3 can be fixed to the partition portion 11 without using a fixing member separate from the sheet-shaped member 3. Furthermore, by imparting adhesiveness to the fire-resistant material layer itself, it is not necessary to provide an adhesive layer, which further simplifies the configuration of the sheet-shaped member 3. When an adhesive fireproof material layer or an adhesive layer is provided on the outermost surface of the sheet-like member 3, a release sheet may be attached to the outermost surface. The release sheet may be peeled off from the outermost surface when the sheet-like member 3 is used.

[0024] The non-combustible material layer used in the sheet-like member 3 is made of a non-combustible material. Non-combustible materials are those defined in the Building Standards Act and the Enforcement Order of the Building Standards Act. Specific examples of the non-combustible material layer include metal foils such as aluminum foil and copper foil, glass cloth, and metal foil composites such as composites of metal foil and glass cloth, such as aluminum glass cloth. Of these, aluminum glass cloth is preferred from the viewpoint of fire resistance. The thickness of the noncombustible material layer 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] The substrate here is a material other than the above-mentioned non-combustible materials, and examples thereof include paper, cloth, resin film, etc. The thickness of the substrate is, for example, 0.01 to 1 mm, and preferably 0.05 to 0.5 mm. The pressure-sensitive adhesive layer is preferably formed from a pressure-sensitive adhesive, and examples of the pressure-sensitive adhesive that can be used include acrylic pressure-sensitive adhesives, urethane pressure-sensitive adhesives, rubber pressure-sensitive adhesives, and silicone resin pressure-sensitive adhesives. The pressure-sensitive adhesive layer may be non-flammable, semi-non-flammable, or flame-retardant, and a flame retardant may be blended into the pressure-sensitive adhesive used. The thickness of the pressure-sensitive adhesive layer is, for example, 5 to 400 μm, and preferably 10 to 150 μm.

[0026] The thickness of the sheet-like member 3 is not particularly limited, but is, for example, 0.1 to 10 mm, and preferably 0.5 to 5 mm.

[0027] When the sheet-like member 3 has a multi-layer structure, it may have a two-layer structure, or a three-layer or more layer structure. Examples of two-layer structures include a non-combustible material layer / fire-resistant material layer, a non-combustible material layer / adhesive layer, a fire-resistant material layer / adhesive layer, a substrate / fire-resistant material layer, and a substrate / non-combustible material layer. Furthermore, examples of three-layer structures that have an adhesive layer include non-combustible material layer / fire-resistant material layer / adhesive layer, substrate / fire-resistant material layer / adhesive layer, substrate / non-combustible material layer / adhesive layer, etc. Other examples of three-layer structures that do not have an adhesive layer include non-combustible material layer / substrate / fire-resistant material layer, substrate / non-combustible material layer / fire-resistant material layer, and substrate / fire-resistant material layer / non-combustible material layer. Examples of structures with four or more layers include a three-layer structure in which an additional adhesive layer is provided as the outermost layer of the three-layer structure not provided with an adhesive layer. Typical examples include adhesive layer / non-combustible material layer / substrate / fire-resistant material layer, non-combustible material layer / substrate / fire-resistant material layer / adhesive layer, substrate / non-combustible material layer ... and substrate / fire-resistant material layer / non-combustible material layer / adhesive layer. Furthermore, in the above multilayer structures, adjacent non-combustible material layers and fire-resistant material layers, non-combustible material layers and substrates, and fire-resistant material layers and substrates may be bonded together with known adhesives, and therefore, in each of the above laminated structures, an adhesive layer may be provided between each of the above layers. In the multilayer structure, the sheet-shaped member 3 may have the same layer configuration throughout its entirety, or may have a partially different structure. For example, a pressure-sensitive adhesive layer may be provided on a portion of the sheet-shaped member 3, so that a portion has a single-layer structure and a portion has a multilayer structure.

[0028] It is preferable that a metal foil composite be laminated on a surface 3A of the sheet-shaped member 3 opposite to a surface 3B facing the partition portion 3. By laminating a metal foil composite on the surface 3A of the sheet-shaped member 3, the fire resistance of the sheet-shaped member 3 can be improved.

[0029] [Cover member] The cover member 5 is provided so as to be connected to the sheet-like member 3, and is a member that covers the sheet-like member 3 provided in the partition section 11. Examples of means for providing the cover member 5 so as to be connected to at least a part of the sheet-like member 3 include means for fixing by known fixing means such as an adhesive, a pressure-sensitive adhesive, an adhesive tape, and fixing members such as tackers and screws. 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. The cover member 5 is sheet-shaped and can be deformed, so that it can easily cover the sheet-shaped member 3.

[0030] 1, the cover member 5 has a slit 50 extending to the outer edge of the cover member 5. The slit 50 is connected to a slit 30 extending to the outer edge of the sheet-shaped member 3. The connection between the slit 30 and the slit 50 makes it possible to insert the inserting body 21 into the inside of the sheet-shaped member 3.

[0031] As shown in FIG. 1, the portion of the cover member 5 that covers the opening 13C of the compartment penetration portion 15 surrounds the penetrating body 21 so as to be in contact with it, and is fixed to the penetrating body 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 cover member 5 can be fixed to the penetrating body 21 simply by twisting or twisting it. The cover member 5 has a portion covering the opening 13C of the compartment penetration portion 15 that 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 wound around it from the outside. The adhesive tape preferably has a tape substrate and an adhesive layer provided on one side of the tape substrate. The tape 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. The cover member 5 may be configured so that the portion covering the opening 13C of the compartment penetration portion 15 surrounds the insert 21 so as to be in contact with it, and may be fixed to the insert 21 by a fixing member such as a stapler or screw installed from the outside.

[0032] It is preferable that the cover member 5 covers the surface 3A of the sheet-like member 3 opposite to the surface 3B facing the partition portion 11, making the surface 3A of the sheet-like member 3 invisible from the outside. By making the surface 3A of the sheet-like member 3 invisible with the cover member 5, the opening 13C where the sheet-like member 3 is installed is covered, making it possible to improve the design of the compartment penetration portion 15 and also to improve the fire resistance of the compartment penetration portion 15.

[0033] The cover member 5 is preferably installed so as to be in contact with the insert 21 and the partition 11. By installing the cover member 5 so as to be in contact with the insert 21 and the partition 11, the opening 13C of the partition 11 can be blocked, and the fire resistance can be improved.

[0034] The cover member 5 is installed so as to form a gap 40 between it and the sheet-like member 3. The gap 40 between the sheet-like member 3 and the cover member 5 allows the cover member 5 to be fixed with a margin for axial movement of the insert 21. Since the cover member 5 is fixed to the insert 21 with a margin, even if the insert 21 arranged inside the sheet-like member 3 and the cover member 5 is moved in the axial direction after the sheet-like member 3 and the cover member 5 are installed, the margin of the cover member 5 prevents the sheet-like member 3 and the cover member 5 from moving together with the insert 21. By preventing the sheet-like member 3 and the cover member 5 from moving together with the insert 21, it is possible to prevent the sheet-like member 3 and the cover member 5 from shifting from the compartment penetration portion 15. In other words, with this configuration, the sheet-like member 3 and the cover member 5 can be maintained and arranged in an appropriate position in the compartment penetration portion 15, and the fire resistance of the compartment penetration portion 15 can be maintained. There is a gap 40 between the sheet-like member 3 and the cover member 5, and various configurations can be used to fix the cover member 5 with a margin for axial movement of the inserting body 21. For example, a configuration in which at least a part of the cover member 5 is made of a flexible or stretchable material that allows it to bend or curve, or a configuration in which at least a part of the cover member 5 is fixed to the inserting body 21 with some slack, can be mentioned.

[0035] The fire-resistant material layer used in the cover member 5 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 10 mm, preferably 0.5 to 5 mm. When the fire-resistant material layer has a thickness equal to or less than these upper limits, flexibility is imparted to the cover member 5. Therefore, even if the cover member 5 has a fire-resistant material layer, it can be wrapped around the outer periphery of the insert 21. Furthermore, when the thickness is equal to or greater than the lower limit, fire prevention performance is more easily ensured.

[0036] The cover member 5 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 surface of the cover member 5. With the above-described configuration, the cover member 5 can be fixed to the partition portion 11 or the insert 21 without using a fixing member separate from the cover member 5. Furthermore, by imparting adhesiveness to the fire-resistant material layer itself, it is not necessary to provide an adhesive layer, and therefore the configuration of the cover member 5 can be further simplified. When the cover member 5 has an adhesive fire-resistant material layer or an adhesive layer on its outermost surface, a release sheet may be attached to the outermost surface. The release sheet may be peeled off from the outermost surface when in use.

[0037] The cover member 5 may be composed of a single layer of fire-resistant material, a single layer of non-combustible material, or both a fire-resistant and non-combustible material layer, but preferably has a non-combustible material layer, and more preferably is composed of a non-combustible material layer. Furthermore, the cover member 5 may have layers other than the fire-resistant and non-combustible material layers, such as a substrate and an adhesive layer. Specific examples of the cover member 5 include metal foils such as aluminum foil, glass cloth, and metal foil composites that are composites of metal foil and glass cloth such as aluminum glass cloth. Among these, aluminum glass cloth is preferred from the viewpoint of fire resistance. The thickness of the non-combustible material layer is not particularly limited, but is, for example, 0.01 to 1 mm, and preferably 0.05 to 0.5 mm. When the non-combustible material layer has a thickness equal to or less than these upper limits, flexibility is imparted to the cover member 5. Therefore, even if the cover member 5 has a non-combustible material layer, it can be wrapped around the outer periphery of the insert 21 while being in close contact with the insert 21. Furthermore, when the thickness is equal to or greater than the lower limit, fire resistance is more easily ensured.

[0038] As described above, the cover member 5 is preferably a sheet that can be deformed to cover the sheet-like member 3, and is preferably thinner than the sheet-like member 3 so that it is flexible and can be easily deformed. The thickness of the cover member 5 is not particularly limited, but is, for example, 0.01 to 1 mm, and preferably 0.05 to 0.5 mm.

[0039] (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 sheet-like member 3, the cover member 5, and the tape-like member 4 described below 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.

[0040] 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, 50 times. The expansion ratio can be calculated by feeding the thermally expandable member into an electric furnace, heating it at 600°C for 30 minutes, measuring the thickness of a test piece, and then calculating the ratio by dividing the thickness of the test piece after heating by the thickness of the test piece before heating.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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 additives commonly used in thermally expandable resin compositions, such as heat stabilizers, lubricants, processing aids, antioxidants, antistatic agents, pigments, crosslinking agents, crosslinking accelerators, etc., as needed, within the range that does not impair the physical properties of the composition. Among these, it is preferable to use processing aids.

[0051] 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, a non-combustible material, or a release sheet, and then dried, cured, or the like as appropriate 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 or tape-like member consisting of a single fire-resistant material layer. Alternatively, a sheet-like member or tape-like member having a multilayer structure may be obtained by laminating the fire-resistant material layer on another layer after peeling it from the release sheet. Alternatively, the fire-resistant material layer may be laminated on another layer while still laminated on the release sheet or another support.

[0052] According to the configuration of this embodiment, the gap 13E inside the opening 13C of the compartment penetration part 15 is closed by the sheet-like member 3 and the cover member 5, and at least one of them contains a fire-resistant material. Therefore, it is possible to impart appropriate fire resistance to the compartment penetration part treatment structure 10. As explained above, the compartment penetration treatment structure 10 is constructed as shown in Fig. 1 by preparing an integrated body of the sheet-like member 3 and the cover member 5, and installing the integrated body so that the sheet-like member 3 closes the gap 13E between the opening 13C of the compartment penetration part 15 and the insert 21. Next, the sheet-like member 3 is covered with the cover member 5, and a part of the cover member 5 is fixed to the insert 21. Therefore, construction is easy. In addition, in this embodiment, the fireproof structure is formed by the sheet-like member 3 and the cover member 5 without placing filler materials such as fire-resistant putty or rock wool inside the compartment penetration portion 15, so there is no variation among workers.

[0053] Furthermore, in this embodiment, at least the cover member 5 is exposed and visible from the outside. If a fixing member for fixing the sheet-like member 3 or the cover member 5 is provided, the fixing member should also be positioned in a position that is visible from the outside. No other members are provided inside the compartment penetration portion 15 than the insert 21. Therefore, the compartment penetration treatment material can be easily inspected visually or by photographing whether it has been installed as specified. Furthermore, forgetting to install it is less likely to occur.

[0054] The compartment penetration structure of this embodiment may also have a multi-layer structure in which at least three layers are laminated, including a substrate layer, a fire-resistant material layer, and an air layer, in a cross section in the axial direction D of the insert passing through the opening of the compartment penetration portion, thereby sealing the gap between the opening of the compartment penetration portion and the insert. The three layers include the air layer as one layer. Furthermore, the term "substrate layer" used in this specification encompasses the above-mentioned non-combustible material layer and substrates other than the non-combustible material layer, but it is preferably a non-combustible material layer. That is, when the sheet-shaped member 3 has a fire-resistant material layer, it functions as a fire-resistant material layer, and when the sheet-shaped member 3 has a non-combustible material layer or a substrate, it functions as a substrate layer. When the sheet-shaped member 3 has both a fire-resistant material layer and a non-combustible material layer or a substrate, it functions as a fire-resistant material layer and a substrate layer. Furthermore, when the cover member 5 has a substrate layer (i.e., a non-combustible material layer or a substrate other than a non-combustible material), the cover member 5 functions as the substrate layer. When the cover member 5 has a fire-resistant material layer, the cover member 5 functions as the fire-resistant material layer. When the cover member 5 has a fire-resistant material layer and a substrate layer, the cover member 5 functions as the fire-resistant agent layer and the substrate layer. The gap 40 between the sheet-like member 3 and the cover member 5 functions as an air layer. In this embodiment, the multilayer structure described above allows the fire-resistant layer to expand and thereby exhibit fire resistance, and the base layer supports the fire-resistant layer, maintaining the position of the expansion residue of the fire-resistant layer in the compartment penetration structure 10, thereby maintaining fire resistance. In addition, the air layer improves heat insulation and provides a margin for when the fire-resistant layer expands.

[0055] [Modification of the first embodiment] In the compartment penetration processing structure 10 shown in Figures 2 and 3, the cover member 5 is shown as four extension portions extending outward from the sheet-like member 3, but as shown in Figure 3, these may be integrally formed and may be a sheet-like member that is one size larger than the sheet-like member 3.

[0056] Furthermore, in the compartment penetration structure 10 shown in FIG. 2, the cover member 5 is adhered to only a portion of the surface 3B of the sheet-like member 3 facing the partition portion 3. However, as shown in FIG. 4, the cover member 5 may be adhered to the entire surface 3B of the sheet-like member 3 facing the partition portion 3. That is, a structure in which the sheet-like member 3 is laminated on one surface of the cover member 5 may be used. In such a structure, the sheet-like member 3 preferably has a fire-resistant material layer, and the cover member 5 preferably has a non-combustible material layer. By combining the sheet-like member 3 and the cover member 5 with a non-combustible material layer, the sheet-like member 3 and the cover member 5 can be easily manufactured as a single unit. Furthermore, an adhesive layer may be provided on the surface of the cover member 5 opposite the side where the sheet-like member 3 is provided, and this adhesive layer allows the cover member 5 to be easily fixed to the outer surface 11A of the partition portion 11.

[0057] 2 and 3, the sheet-like member 3 and the cover member 5 are integral with each other, but the sheet-like member 3 and the cover member 5 may be separate members. When the sheet-like member 3 and the cover member 5 are separate members, it is preferable that the sheet-like member 3 and the cover member 5 are each fixed to the outer surface 11A of the partition portion 11.

[0058] [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 the compartment penetration treatment material is configured to include a tape-shaped member 4 and a cover member 5, as shown in Figures 5 and 6. The differences between the second embodiment and the first embodiment will be described below. Furthermore, parts whose description is omitted are the same as those in the first embodiment. Furthermore, in the following description, parts having the same configuration as those in the first embodiment will be given the same reference numerals. The details of the structure of the cover member 5 itself are the same as those in the first embodiment, and at least one of the tape-shaped member 4 and the cover member 5 has a fire-resistant material.

[0059] [Tape-shaped member] 5 and 6, the tape-shaped member 4 is wound one or more times around the outer periphery of the insert 21. This forms an end surface 4A on the tape-shaped member 4, and the end surface 4A can close the gap 13E between the opening 13C and the insert 21.

[0060] The tape-shaped member 4 has at least one of a non-combustible material layer and a fire-resistant material layer. Similarly, the cover member 5 has at least one of a fire-resistant material layer and a non-combustible material layer. However, either the tape-shaped member 4 or the cover member 5 has a fire-resistant material layer (fire-resistant material). This allows the compartment penetration structure 10 to ensure fire resistance. Furthermore, from the viewpoint of ensuring fire resistance, it is preferable that at least the tape-shaped member 4 has a fire-resistant material layer, and more preferably, the tape-shaped member 4 has a fire-resistant material layer and the cover member 5 has a non-combustible material layer.

[0061] The fire-resistant material layer used in the tape-shaped member 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 the above-mentioned thermally expandable resin composition. 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 10 mm, preferably 0.5 to 5 mm. When the fire-resistant material layer has a thickness equal to or less than these upper limits, flexibility is imparted to the tape-shaped member 4. Therefore, for example, even if the tape-shaped member 4 has a fire-resistant material layer, it can be wound around the outer periphery of the insert 21 while being in close contact with the insert 21. Furthermore, when the thickness is equal to or greater than the lower limit, fire resistance is more easily ensured.

[0062] The tape-shaped member 4 may be composed of a single layer of fire-resistant material, a single layer of non-combustible material, or both a fire-resistant layer and a non-combustible material layer. Furthermore, the tape-shaped member 4 may have layers other than the fire-resistant layer and the non-combustible material layer, such as a substrate and an adhesive layer.

[0063] The tape-shaped member 4 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 surface of the tape-shaped member 4. With the above-described configuration, the tape-shaped member 4 can be fixed to the insert 21 without using a fixing member separate from the tape-shaped member 4. Furthermore, by imparting adhesiveness to the fire-resistant material layer itself, it is not necessary to provide an adhesive layer, which further simplifies the configuration of the tape-shaped member 4. When an adhesive fire-resistant material layer or an adhesive layer is provided on the outermost surface of the tape-shaped member 4, a release sheet may be attached to the outermost surface. The release sheet may be peeled off from the outermost surface when the tape-shaped member 4 is used.

[0064] The non-combustible material layer used in the tape-shaped member 4 is made of a non-combustible material. Non-combustible materials are those defined in the Building Standards Act and the Enforcement Order of the Building Standards Act. Specific examples of the non-combustible material layer include metal foils such as aluminum foil and copper foil, glass cloth, and metal foil composites that are composites of metal foil and glass cloth, such as aluminum glass cloth. Of these, aluminum glass cloth is preferred from the viewpoint of fire resistance. The thickness of the non-combustible material layer is not particularly limited, but is, for example, 0.01 to 1 mm, and preferably 0.05 to 0.5 mm. When the non-combustible material layer has a thickness equal to or less than these upper limits, flexibility is imparted to the tape-shaped member 4. Therefore, even if the tape-shaped member 4 has a non-combustible material layer, it can be wound around the outer periphery of the insert 21 while being in close contact with the insert 21. Furthermore, when the thickness is equal to or greater than the lower limit, fire resistance is more easily ensured.

[0065] The substrate here is a material other than the above-mentioned non-combustible materials, and examples thereof include paper, cloth, resin film, etc. The thickness of the substrate is, for example, 0.01 to 1 mm, and preferably 0.05 to 0.5 mm. The pressure-sensitive adhesive layer is preferably formed from a pressure-sensitive adhesive, and examples of the pressure-sensitive adhesive that can be used include acrylic pressure-sensitive adhesives, urethane pressure-sensitive adhesives, rubber pressure-sensitive adhesives, and silicone resin pressure-sensitive adhesives. The pressure-sensitive adhesive layer may be non-flammable, semi-non-flammable, or flame-retardant, and a flame retardant may be blended into the pressure-sensitive adhesive used. The thickness of the pressure-sensitive adhesive layer is, for example, 5 to 400 μm, and preferably 10 to 150 μm.

[0066] The thickness of the tape-shaped member 4 is not particularly limited, but is, for example, 0.1 to 10 mm, and preferably 0.5 to 5 mm.

[0067] When the tape-shaped member 4 has a multi-layer structure, it may have a two-layer structure, or a three-layer or more layer structure. Examples of two-layer structures include a non-combustible material layer / fire-resistant material layer, a non-combustible material layer / adhesive layer, a fire-resistant material layer / adhesive layer, a substrate / fire-resistant material layer, and a substrate / non-combustible material layer. Furthermore, examples of three-layer structures that have an adhesive layer include non-combustible material layer / fire-resistant material layer / adhesive layer, substrate / fire-resistant material layer / adhesive layer, substrate / non-combustible material layer / adhesive layer, etc. Other examples of three-layer structures that do not have an adhesive layer include non-combustible material layer / substrate / fire-resistant material layer, substrate / non-combustible material layer / fire-resistant material layer, and substrate / fire-resistant material layer / non-combustible material layer. Examples of structures with four or more layers include a three-layer structure in which an additional adhesive layer is provided as the outermost layer of the three-layer structure not provided with an adhesive layer. Typical examples include adhesive layer / non-combustible material layer / substrate / fire-resistant material layer, non-combustible material layer / substrate / fire-resistant material layer / adhesive layer, substrate / non-combustible material layer ... and substrate / fire-resistant material layer / non-combustible material layer / adhesive layer. Furthermore, in the above multilayer structures, adjacent non-combustible material layers and fire-resistant material layers, non-combustible material layers and substrates, and fire-resistant material layers and substrates may be bonded together with known adhesives, and therefore, in each of the above laminated structures, an adhesive layer may be provided between each of the above layers. In the multilayer structure, the tape-shaped member 4 may have the same layer configuration throughout its entirety, or may have a different structure in parts. For example, a pressure-sensitive adhesive layer may be provided in part of the tape-shaped member 4, so that part of the tape-shaped member 4 has a single-layer structure and part of the tape-shaped member 4 has a multilayer structure.

[0068] The tape-shaped member 4 wound around the outer periphery of the inserter 21 may be in close contact with the inserter 21, and therefore may be deformed appropriately to fit the shape of the inserter 21. The tape-shaped member 4 is fixed to the outer periphery of the inserter 21. The tape-shaped member 4 may be fixed to the outer periphery of the inserter 21 by an adhesive layer or a fire-resistant material layer disposed on the inner periphery of the tape-shaped member 4. The tape-shaped member 4 may be fixed to the inserter 21 by a fixing member provided separately from the tape-shaped member 4. Examples of such fixing members include a string-shaped member wound from the outer periphery of the tape-shaped member 4 or an adhesive tape. The tape-shaped member 4 may also be fixed to the inserter 21 by a combination of two or more of these.

[0069] [Cover member] The cover member 5 is provided so as to be connected to the tape-shaped member 4, and is a member that covers the tape-shaped member 4 provided in the partition section 11. Examples of means for providing the cover member 5 so as to be connected to at least a part of the tape-shaped member 4 include means for fixing by known fixing means such as an adhesive, a pressure-sensitive adhesive, and an adhesive tape, as well as fixing members such as tackers and screws. Here, the adhesive, pressure-sensitive adhesive, and 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, pressure-sensitive adhesive, etc. The cover member 5 is sheet-shaped and can easily cover the sheet-shaped member 3 by being deformed.

[0070] As shown in Fig. 5, the cover member 5 has slits 50 through which the penetrating body 21 is inserted, and at least one of the slits 50 extends to the outer edge of the cover member 5. The slits 50 are formed by cutting. The cover member 5 allows the penetrating body 21 to be inserted into the cover member 5 through the slit 50 extending to the outer edge. Note that the slit 50 may have a form including a hole through which the penetrating body 21 is inserted and a slit 30 extending from the hole to the outer edge of the cover member 5.

[0071] 6, the cover member 5 with the insert 21 inserted through the slit 50 is placed on the outer surface 11A so as to cover the gap 13E between the opening 13C and the insert 21 from the outside of the partition 11, whereby the gap 13E between the opening 13C and the insert 21 is closed by the cover member 5. The cover member 5 is placed so as to be in contact with both the outer surface 11A of the partition 11 and the outer periphery of the insert 21. With the above configuration, a gap may be formed between the cover member 5 and the inserting body 21, but such a gap is blocked by the tape-shaped member 4. Therefore, the entire gap 13E between the opening 13C of the compartment penetrating part 15 and the inserting body 21 is blocked by the tape-shaped member 4 and the cover member 5.

[0072] It is preferable that the cover member 5 covers the tape-shaped member 4 and makes the tape-shaped member 4 invisible from the outside. By making the tape-shaped member 4 invisible with the cover member 5, the opening 13C in which the tape-shaped member 4 is placed is covered, thereby improving the design of the compartment penetration part 15 and also improving the fire resistance of the compartment penetration part 15.

[0073] According to the configuration of this embodiment, the gap 13E inside the opening 13C of the compartment penetration 15 is closed by the tape-shaped member 4 and the cover member 5, and at least one of them contains a fire-resistant material. Therefore, the compartment penetration treatment structure 10 can be provided with appropriate fire resistance. As explained above, the compartment penetration processing structure 10 can be constructed by wrapping the tape-shaped member 4 around the insert 21 one or more times, placing the tape-shaped member 4 so as to close the gap 13E between the opening 13C of the compartment penetration part 15 and the insert 21, and then placing the cover member 5 so as to cover the tape-shaped member 4 and fixing a part of the cover member 5 to the insert 21. Therefore, construction is easy. In addition, in this embodiment, the fireproof structure is formed by the tape-shaped member 4 and the cover member 5 without placing filler materials such as fire-resistant putty or rock wool inside the compartment penetration portion 15, so there is no variation among workers.

[0074] Furthermore, in this embodiment, at least the cover member 5 is exposed and visible from the outside. If a fixing member for fixing the cover member 5 is provided, the fixing member should also be positioned in a position that is visible from the outside. No other members are provided inside the compartment penetration portion 15 except for the insert 21. Therefore, the compartment penetration treatment material can be easily inspected visually or by photographing whether it has been installed as specified. Furthermore, forgetting to install it is less likely to occur.

[0075] In addition, the compartment penetration processing structure of this embodiment can also be a structure having a multi-layer structure in which, in a cross section in the axial direction D of the insert passing through the opening of the compartment penetration part, it includes a base material layer, a fire-resistant material layer, and an air layer, which are stacked in at least three layers, and which seals the gap between the opening of the compartment penetration part and the insert. That is, when the tape-shaped member 4 has a fire-resistant material layer, it functions as the fire-resistant material layer, and when the tape-shaped member 4 has a non-combustible material layer or a substrate, the tape-shaped member 4 forms the substrate layer. Also, when the tape-shaped member 4 has a fire-resistant material layer and a non-combustible material layer or a substrate, it functions as the fire-resistant material layer and the substrate layer. Furthermore, when the cover member 5 has a substrate layer (i.e., a non-combustible material layer or a substrate other than a non-combustible material), the cover member 5 functions as the substrate layer. When the cover member 5 has a fire-resistant material layer, the cover member 5 functions as the fire-resistant material layer. When the cover member 5 has a fire-resistant material layer and a substrate layer, the cover member 5 functions as the fire-resistant agent layer and the substrate layer. The gap 40 between the tape-shaped member 4 and the cover member 5 functions as an air layer. In this embodiment, the multi-layer structure allows the fire-resistant layer to expand and thereby exhibit fire resistance, the base material layer supports the fire-resistant layer and maintains the position of the residue of the fire-resistant layer in the compartment penetration processing structure 10, thereby maintaining fire resistance, and the air layer functions to improve insulation and provide a margin when the fire-resistant layer expands.

[0076] [First Modification of the Second Embodiment] 5 and 6, the compartment penetration structure 10 shows an aspect in which the end surface 4A of the tape-shaped member 4 blocks the gap 13E between the opening 13C and the insert 21, but as shown in Fig. 7, an aspect in which the end surface 4A of the tape-shaped member 4 does not block the gap 13E is also possible. In this aspect, it is preferable that the tape-shaped member 4 has a layer made of a thermally expandable member, and when the tape-shaped member 4 is heated, the expanded end surface 4A of the tape-shaped member 4 blocks the gap 13E.

[0077] [Second Modification of the Second Embodiment] Furthermore, although the compartment penetration structure 10 shown in FIGS. 5 and 6 has an embodiment in which the tape-shaped member 4 and the cover member 5 are separate bodies, as shown in FIG. 8, the tape-shaped member 4 and the cover member 5 may be integrated. That is, the tape-shaped member 4 may be laminated on one side of the cover member 5. In such a structure, the tape-shaped member 4 preferably has a fire-resistant material layer, and the cover member 5 preferably has a non-combustible material layer. By combining the tape-shaped member 4 and the cover member 5 with a non-combustible material layer, the tape-shaped member 4 and the cover member 5 can be easily manufactured as an integrated unit. Furthermore, an adhesive layer may be provided on the surface of the cover member 5 on which the tape-shaped member 4 is provided, and this adhesive layer allows the cover member 5 to be easily fixed to the insertion body 21. In the compartment penetration structure 10 in the second modified example of the second embodiment, the tape-shaped member 4 is wound around the outer periphery of the insert 21 one or more times, which allows the end face of the tape-shaped member 4 formed on the partition section 11 side to close the gap 13E between the opening 13C and the insert 21. Then, the cover member 5 provided integrally with the tape-shaped member 4 surrounds the insert 21 so as to be in contact with it and is fixed to the insert 21, so that the cover member 5 covers the tape-shaped member 4 and makes the tape-shaped member 4 invisible from the outside.

[0078] [Third embodiment] Next, a third embodiment of the present invention will be described in detail. The third embodiment differs from the first and second embodiments in that the compartment-penetrating treatment material is configured to include a sheet-like member 3, a tape-like member 4, and a cover member 5, as shown in Figures 9 and 10. The following describes the differences between the third embodiment and the first and second embodiments. Furthermore, parts whose description is omitted are the same as those in the first and second embodiments. Furthermore, in the following description, parts having the same configuration as those in the first and second embodiments are given the same reference numerals. The detailed structures of the sheet-shaped member 3, tape-shaped member 4 and cover member 5 themselves are the same as those of the first and second embodiments, and at least one of the sheet-shaped member 3, tape-shaped member 4 and cover member 5 contains a fire-resistant material.

[0079] 9 and 10, the tape-shaped member 4 is disposed further outward than the sheet-shaped member 3 with respect to the partition portion 11. The tape-shaped member 4 is wound around the outer periphery of the insert 21 one or more times. As a result, the tape-shaped member 4 is disposed so that its end surface 4A covers the space between the sheet-shaped member 3 and the insert 21. With the above configuration, a gap may be formed between the sheet-like member 3 and the insert 21, but such a gap is blocked by the tape-like member 4. Therefore, the entire gap 13E between the opening 13C of the compartment penetration part 15 and the insert 21 is blocked by the sheet-like member 18 and the tape-like member 19.

[0080] The cover member 5 is provided so as to be connected to at least one of the sheet-like member 3 and the tape-like member 4, and is in the form of a cover that covers at least one of the sheet-like member 3 and the tape-like member 4 provided in the partition section 11. Examples of means by which the cover member 5 is provided so as to be connected to at least a part of the sheet-like member 3 and the tape-like member 4 include means for fixing by known fixing means such as an adhesive, a pressure-sensitive adhesive, an adhesive tape, and fixing members such as tackers and screws. 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.

[0081] The cover member 5 preferably covers the surface 3A of the sheet-like member 3 opposite to the surface 3B facing the partition portion 11, making the sheet-like member 3 invisible from the outside. Similarly, the cover member 5 preferably makes the tape-like member 4 invisible from the outside. By making at least one of the surface 3A of the sheet-like member 3 and the tape-like member 4 invisible with the cover member 5, the opening 13C in which the sheet-like member 3 is installed is covered, thereby improving the design of the compartment penetration portion 15 and the fire resistance of the compartment penetration portion 15.

[0082] The cover member 5 is preferably installed so as to be in contact with the insert 21 and the partition 11. By installing the cover member 5 so as to be in contact with the insert 21 and the partition 11, the opening 13C of the partition 11 can be blocked, and the fire resistance can be improved.

[0083] According to the configuration of this embodiment, the gap 13E inside the opening 13C of the compartment penetration 15 is closed by at least one of the sheet-like member 3, the tape-like member 4, and the cover member 5, and at least one of these members contains a fire-resistant material. Therefore, the compartment penetration treatment structure 10 can be provided with appropriate fire resistance. As explained above, in the compartment penetration processing structure 10, the sheet-like member 3 is installed so as to close the gap 13E between the opening 13C of the compartment penetration portion 15 and the insert 21. Next, the tape-like member 4 is wrapped around the insert 21 one or more times, and the tape-like member 4 is installed so as to close the gap 13E between the opening 13C of the compartment penetration portion 15 and the insert 21. Next, both the sheet-like member 3 and the tape-like member 4 are covered with the cover member 5, and a portion of the cover member 5 is fixed to the insert 21, thereby completing the construction. Therefore, the construction is easy. Furthermore, in this embodiment, the fireproof structure is formed by the sheet-like member 3, the tape-like member 4 and the cover member 5 without placing filler materials such as fire-resistant putty or rock wool inside the compartment penetration portion 15, so there is no variation among workers.

[0084] Furthermore, in this embodiment, at least the cover member 5 is exposed and visible from the outside. If a fixing member for fixing the cover member 5 is provided, the fixing member should also be positioned in a position that is visible from the outside. No other members are provided inside the compartment penetration portion 15 except for the insert 21. Therefore, the compartment penetration treatment material can be easily inspected visually or by photographing whether it has been installed as specified. Furthermore, forgetting to install it is less likely to occur.

[0085] In addition, the compartment penetration processing structure of this embodiment can also be a structure having a multi-layer structure in which, in a cross section in the axial direction D of the insert passing through the opening of the compartment penetration part, it includes a base material layer, a fire-resistant material layer, and an air layer, which are stacked in at least three layers, and which seals the gap between the opening of the compartment penetration part and the insert. That is, as described above, the sheet-like member 3, the tape-like member 4, and the cover member 5 each function as a fire-resistant layer when they have a fire-resistant material layer, as a substrate layer when they have a non-combustible material layer or a substrate, and as a fire-resistant layer and a substrate layer when they have both a fire-resistant material layer and a non-combustible material layer or a substrate. The gap 40 between the sheet-like member 3 / tape-like member 4 and the cover member 5 functions as an air layer. In this embodiment, too, the multi-layer structure allows the fire-resistant material layer to expand and thereby exhibit fire resistance, the base material layer supports the fire-resistant material layer and maintains the position of the residue of the fire-resistant material layer in the compartment penetration processing structure 10, thereby maintaining fire resistance, and the air layer functions to improve insulation and provide a margin when the fire-resistant material layer expands.

[0086] [Other embodiments] The present invention is not limited to the configurations of the first to third embodiments described above, and any improvements and modifications may be made without departing from the technical spirit of the present invention. For example, in the first to third embodiments, the compartment penetration treatment material may have a member connected to at least one of the sheet-like member 3 and the tape-like member 4 and disposed inside the compartment penetration part 15. Examples of such members include fireproof materials and accessories. As specific examples, a modified example of the first embodiment is shown in Fig. 11, and a modified example of the second embodiment is shown in Fig. 12. As the fire-resistant material, for example, a block-shaped fire-resistant material 60 as shown in Figs. 11 and 12 is used, and the block-shaped fire-resistant material 60 may be connected to the sheet-shaped member 3 or the tape-shaped member 4. The manner of connection is not particularly limited, and for example, the fire-resistant material 60 may be laminated on one side of the sheet-shaped member 3 or the tape-shaped member 4, or may be connected to an end face of the sheet-shaped member 3 or the tape-shaped member 4. As described above, the fire-resistant material 60 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.

[0087] 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.

[0088] 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.

[0089] In addition, in each of the above embodiments, in order to improve the sound absorption properties of the compartment penetration processing structure 10, at least one of the sheet-like member 3, the tape-like member 4 and the cover member 5 can be configured to have a sound-absorbing layer (not shown). The sound absorbing layer can be made of glass wool, rock wool, soft urethane foam, ceramic fiber, cellulose fiber, needle punch mat, or the like. The thickness of the sound absorbing layer is not particularly limited, but is, for example, 0.1 to 10 mm, and preferably 0.5 to 5 mm. When the sound absorbing layer has a thickness equal to or less than these upper limits, it becomes easy to install the sheet-like member 3, the tape-like member 4, and the cover member 5. When the sound absorbing layer has a thickness equal to or more than these lower limits, it becomes easier to ensure sound absorbing performance.

[0090] In addition, in each of the above embodiments, in order to improve the sound insulation properties of the compartment penetration processing structure 10, at least one of the sheet-like member 3, the tape-like member 4 and the cover member 5 can be configured to have a sound insulation layer (not shown). The sound-insulating layer can be composed of an asphalt sheet, an olefin sheet, an iron-based soft sheet, or the like. The sound-insulating layer can also be composed of a resin material highly filled with an inorganic filler such as calcium carbonate. Specifically, the sound-insulating layer is preferably composed of a resin composition containing 300 to 600 parts by mass of inorganic filler per 100 parts by mass of olefin-based resin, more preferably 350 to 550 parts by mass, and even more preferably 400 to 500 parts by mass. In this way, resin materials highly filled with inorganic filler have a large mass per unit volume, thereby effectively demonstrating sound-insulating effects. The thickness of the sound-insulating layer is not particularly limited, but is, for example, 0.1 to 10 mm, and preferably 0.5 to 5 mm. When the sound-insulating layer has a thickness equal to or less than these upper limits, it becomes easy to install the sheet-like member 3, the tape-like member 4, and the cover member 5. When the sound-insulating layer has a thickness equal to or more than these lower limits, it becomes easier to ensure sound-insulating performance.

[0091] [Fourth embodiment] As shown in Figures 13 to 15, a compartment penetration processing structure 10 according to a fourth embodiment of the present invention has a multi-layer structure 100 that closes a gap 13E between an opening 13C of a compartment penetration portion 15 provided in a partition portion 11 and an insert 21. The multilayer structure 100 is a structure in which at least three layers are laminated, including a base material layer 110, a fireproof material layer 120, and an air layer 130, in a cross section in the axial direction D of the insert 21 passing through the opening 13C of the compartment penetration part 15.

[0092] [Base material layer] 13 and 14, the base material layer 110 can be arranged on the fire-resistant material layer 120 via an air layer 130, and can be a layer that covers the fire-resistant material layer 120. Alternatively, the base material layer 110 can be configured as a layer that is laminated on the fire-resistant material layer 120, covers the fire-resistant material layer 120, and further supports the fire-resistant material layer 120, as shown in FIG. It is preferable that the base material layer 110 covers the fire-resistant material layer 120 so that the fire-resistant material layer 120 cannot be seen from the outside. By providing the base material layer 110, the opening 13C is covered, which improves the design of the compartment penetration part 15 and also improves the fire resistance of the compartment penetration part 15. Furthermore, the base material layer 110 has the function of retaining the expansion residue when the fire-resistant material layer 120 thermally expands.

[0093] Examples of the base material layer 110 include the above-mentioned cover member, base material, non-combustible material, paper, cloth, resin film, etc. Among these, non-combustible material is preferable. The base material layer 110 is not limited to a single layer, and may be made up of multiple layers. The base material layer 110 made up of multiple layers may be made up of multiple layers of the same type, or multiple layers of different types. The thickness of the base layer 110 is, for example, 0.01 to 1 mm, and preferably 0.05 to 0.5 mm.

[0094] As shown in Figures 13 and 14, the portion of the base material layer 110 that covers the opening 13C of the compartment penetration portion 15 surrounds the penetrating body 21 so as to be in contact with it, and is fixed to the penetrating body 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 base material layer 110 can be fixed to the penetrating body 21 simply by twisting or twisting it. The base material layer 110 has a portion covering the opening 13C of the compartment penetration portion 15 that surrounds the insert 21 and is fixed to the insert 21 by an adhesive tape wound around it from the outside. The adhesive tape preferably has a base material and an adhesive layer provided on one side of the base material. The base material may be made of paper, resin film, cloth, or any 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. The base material layer 110 may be configured so that the portion covering the opening 13C of the compartment penetration portion 15 surrounds the insert 21 so as to be in contact with it, and may be fixed to the insert 21 by a fixing member such as a stapler or screw installed from the outside.

[0095] 13 to 15, the portion of the base material layer 110 that is located near the outer surface 11A of the partition section 11 may be fixed to the outer surface 11A of the partition section 11. In this case, the portion of the base material layer 110 that is located near the outer surface 11A of the partition section 11 may be fixed to the outer surface 11A of the partition section 11 with a fixing member such as a stapler or a screw that is installed from the outside.

[0096] [Refractory material layer] The fire-resistant material layer 120 may be composed of a single fire-resistant material layer, or may be composed of multiple fire-resistant agent layers, or may be laminated with a layer other than a fire-resistant material layer. For example, a base layer such as a non-combustible material layer may be laminated on the fire-resistant agent layer, or an adhesive layer may be laminated on the fire-resistant agent layer.

[0097] [Air layer] The air layer 130 exerts a function of imparting heat insulation to the compartment penetration structure 10. It also maintains a margin for the fire-resistant material layer 120 to exert its fire resistance. In this specification, the air layer 130 refers to the space provided between the base material layer 110 and the fire-resistant material layer 120 in a cross section in the axial direction D of the insert 21 passing through the opening 13C of the compartment penetration portion 15 (see Figures 13 and 14), or the space provided between the base material layer 110 and the fire-resistant material layer 120 and the outer surface 11A of the partition portion 11 (see Figure 15).

[0098] According to the configuration of this embodiment described above, the multi-layer structure allows the fire-resistant material layer to expand and thereby exhibit fire resistance, the base material layer supports the fire-resistant material layer and maintains the position of the residue of the fire-resistant material layer in the compartment penetration processing structure 10, thereby maintaining fire resistance, and the air layer functions to improve insulation properties and provide a margin when the fire-resistant material layer expands. In addition, in this embodiment, the gap 13E inside the opening 13C of the compartment penetration portion 15 is sealed by the multi-layer structure, and the fire-resistant material layer that constitutes the multi-layer structure has at least fire resistance, thereby imparting appropriate fire resistance to the compartment penetration portion processing structure 10. Furthermore, in this embodiment, a fireproof structure is formed by a multi-layer structure without placing filler materials such as fireproof putty or rock wool inside the compartment penetration portion 15, so there is no variation depending on the worker.

[0099] 13 and 14, the base material layer 110 can be the cover member, and the fire-resistant material layer 120 can be the tape-like or sheet-like member. In the compartment penetration structure shown in Fig. 15, the laminate of the base material layer 110 and the fire-resistant material layer 120 can be the cover member. Furthermore, in the fourth embodiment, at least one of the base material layer 110 and the fireproof material layer 120 may have a sound absorbing layer or a sound insulating layer. Details of the sound absorbing layer and the sound insulating layer are as described above. [Explanation of symbols]
