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, a construction method for the compartment penetration structure, and a cover member. [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).

DETAILED DESCRIPTION OF THE INVENTION

[0010] The present invention will be described in more detail below using embodiments.

[0011] [First embodiment] The compartment penetration structure according to the first embodiment of the present invention is a compartment penetration structure, as shown in Figures 1 and 2, which is formed in a partition 11 of a building and has a compartment penetration section 15, into 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 the sheet-like member 3 and the cover member 5, and further includes fastening members 6A and 6B.

[0012] 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.

[0013] In this specification, the components (in this embodiment, the sheet-like member 3, the cover member 5, etc.) that are installed in the compartment penetration portion 15 and used to form the compartment penetration processing structure 10 may be 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.

[0014] The compartment penetration structure 10 according to the first embodiment includes a sheet-like member 3 and a cover member 5 as compartment penetration treatment materials, and the cover member 5 is fixed to the compartment penetration structure by a fastening material 6. At least one of the sheet-like member 3 and the cover member 5 has a fire-resistant material as described below.

[0015] [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.

[0016] The sheet-like member 3 may be fixed to the outer surface 11A of the partition portion 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 portion 11 by a fixing member that is a separate member from the sheet-like member 3, such as a tacker or a screw. Of course, the sheet-like member 3 may be fixed to the partition portion 11 by a combination of two or more of these methods. Furthermore, the sheet-like member 3 may be fixed to the partition portion 11 together with the cover member 5 by the fastening material 6A, or may be fixed to the partition portion 11 by a fixing member and the fastening material 6A.

[0017] 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.

[0018] 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.

[0019] 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 in the sheet-shaped member 3 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.

[0020] The sheet-like 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-like member 3 may also have layers other than the fire-resistant layer and the non-combustible material layer, such as a substrate layer and an adhesive layer.

[0021] 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.

[0022] 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.

[0023] The substrate used as the substrate layer 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.

[0024] 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.

[0025] 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.

[0026] It is preferable that a metal foil composite be laminated on a surface 3A (see FIG. 2) opposite to a surface 3B of the sheet-shaped member 3 that faces the partition portion 3. By laminating a metal foil composite on surface 3A of the sheet-shaped member 3, the fire resistance of the sheet-shaped member 3 can be improved.

[0027] [Cover member] The cover member 5 is placed so as to cover the opening 13C of the compartment penetration part 15 provided in the partition part 11. Here, in this embodiment, as long as the cover member 5 is placed in a position that covers the opening, there may be another member between the cover member 5 and the opening 13C, and in this embodiment, the sheet-like member 3 is placed between the cover member 5 and the opening 13C, and the opening 13C is covered via the sheet-like member 3. With this configuration, the cover member 5 in this embodiment covers the sheet-shaped member 3 and also closes a part of the gap 13E that is not closed by the sheet-shaped member 3.

[0028] 1, the cover member 5 includes a first cover portion 50 and a plurality of second cover portions 51 (51A to 51E) that are connected to the first cover portion 50 and spaced apart from one another. The second cover portions 51 are arranged in a line along one side of the first cover portion 50. By providing the cover member 5 with a first cover portion and a second cover portion, it becomes easier to position the second cover portion 51 on the partition portion 11 while the first cover portion 50 surrounds the inserting body 21, making it easier to install the cover member 5 so as to cover the opening 11C.

[0029] The cover member 5 is provided with marks (first mark 52 and second marks 53A to 53D) that indicate the installation positions of the fastening members 6A and 6B. The first cover portion 50 of the cover member 5 has a mark (first mark 52) indicating the installation position of the fastening material 6B. As shown in FIG. 2, after the first cover portion 50 is wrapped around the inserting body 21 and installed, the fastening material 6B is installed on the first mark 52, thereby fastening the first cover portion 50 to the inserting body 21. In addition, the second cover portion 51 of the cover member 5 has marks (second marks 53A to 53D) that indicate the installation position of the fastening material 6A, and as shown in Figure 2, after the second cover portion 51 is installed on the sheet-like member 3, the fastening material 6A is installed from above the second marks 53A to 53D, thereby fastening the second cover portion 51 to the sheet-like member 3. The marks (second marks 53A to 53D) can also be said to be marks that indicate the fixing positions of the first cover portion 50 and the second cover portion 51 to the inserting body 21 and the partition portion 11.

[0030] 2 and 3, the second cover portion 51 of the cover member 5 is placed on the sheet-like member 3 that is placed on the outer surface 11A. Then, the second cover portion 51 of the cover member 5 is fastened to the partition portion 11 via the sheet-like member 3 by inserting the fastening material 6A from the outside of the second cover portion 51 through the second marks 53A to 53D into the partition portion 11 of the compartment penetration portion 15. The fastening material 6A for fastening the second cover portion 51 may be any material that can be inserted from the second marks 53A to 53D on the cover member 5 into the partition portion 11 of the compartment penetration portion 15 to fix and fasten the cover member 5 to the compartment penetration portion 15, and examples thereof include fixing members such as tackers and screws. In order to improve the fixing strength of the cover member 5, it is preferable to interpose a washer 60 between the fastening material 6A and the cover member 5.

[0031] The first cover portion 50 of the cover member 5 surrounds the insert 21 so as to be in contact with it, and is fastened to the insert 21 by being restrained and fixed from the outside by the fastening material 6B along the first mark 52 attached to the first cover portion 50. In a configuration in which the cover member 5 is fixed by being restrained from the outside along the first mark 52 by the fastening material 6B, a bendable material can be used as the fastening material 6B, and it is preferable that the fastening material 6B is a wire material including a wire or an adhesive tape. The wire material may be a metal wire alone, or a resin-coated wire such as Nejirikko (registered trademark) in which a metal wire is coated with a resin, or a wire and fiber entangled material such as a mould. When a wire material is used, the cover member 5 can be fixed to the inserting body 21 simply by twisting or twisting it. The adhesive tape can be used to secure the cover member 5 to the insert by wrapping the first cover portion 50 from the outside along the first mark 52, for example. The adhesive tape preferably has a substrate and an adhesive layer provided on one side of the substrate. The substrate can be made of paper, resin film, cloth, or any of the non-flammable materials described above. The adhesive layer can be made of, for example, an acrylic adhesive, a urethane adhesive, a rubber adhesive, or a silicone resin adhesive. The adhesive can also contain a known flame retardant. In a configuration in which the cover member 5 is secured by the fastening material 6B from the outside along the first mark 52, a fastening member such as a tacker or a screw installed from the outside of the first mark 52 can be used as the fastening material 6B. To improve the fixing strength, the fastening material 6B that fastens the first cover portion 50 of the cover member 5 to the insert 21 can be combined with the means shown in the fixing form described above. Specifically, the fastening material 6B can be a combination of a wire member and adhesive tape, or a combination of a wire member and a fixing member such as a screw or a tacker.

[0032] As described above, fastening material 6B is placed on first mark 52, and first mark 52 is at least partially covered by fastening material 6B. Fastening material 6A is placed on second marks 53A to 53D, and each of second marks 53A to 53D is at least partially covered by fastening material 6A. With this configuration, at least a portion of each of first mark 51 and second marks 53A to 53D is not visible from the outside, making it easy to confirm that they are placed as specified.

[0033] The shape and number of second cover portions 51 are not particularly limited. For example, if the second cover portions 51 are installed in the compartment penetration portion 15 in a rectangular shape as shown in FIG. 3, each second cover portion 51 may be shaped as a right-angled isosceles triangle with an angle a between two sides of the second cover portion 51 of 90°, as shown in FIGS. 4(a) and (b), and the number of second cover portions 51 may be four or more. The cover member 5 shown in FIG. 4(a) has five second cover portions 51, and second cover portion 51E is arranged so as to overlap second cover portion 51A. The double arrangement improves fastening strength and suppresses the fall of residue. While it is preferable to have a second cover portion arranged so as to overlap underneath, as shown in FIG. 4(a), it is not necessary, as shown in FIG. 4(b). When the second cover parts 51 are installed in the compartment penetration part 15 in a triangular shape as shown in Fig. 5(a), it is preferable that the shape of each second cover part 51 is an isosceles triangle in which the angle b formed by the two sides of the second cover part 51 is less than 90°, and that there are three or more second cover parts 51, as shown in Fig. 5(b). Specifically, when the second cover parts 51 are installed in the compartment penetration part 15 in an equilateral triangle, it is preferable that the angle b formed by the two sides of the second cover parts 51 is 60°. When the second cover part 51 is installed in the compartment penetration part 15 in the shape of a star polygon as shown in Fig. 6(a), it is preferable that the shape of each second cover part 51 is an isosceles triangle in which the angle c formed by two sides of the second cover part 51 is less than 90°, and that the number of second cover parts 51 is equal to or greater than the number of vertices of the star polygon, as shown in Fig. 6(b). Specifically, when the number of vertices of the star polygon is five as shown in Fig. 6(a), it is preferable that the number of second cover parts 51 is five or greater.

[0034] In the above description, the shape of each second cover portion 51 is shown as a triangle with two sides approaching each other, but is not limited to the above shape. For example, the second cover parts 51 may be installed in the compartment penetration part 15 in the form of a radially arranged rectangle as shown in Fig. 7(a). In this case, each of the second cover parts 51 may be rectangular as shown in Fig. 7(b). In this case, the number of second cover parts 51 is not particularly limited. In any installation form of the cover member 5, the marks (first mark 52 and second marks 53A to 53D) may be deformed to fit the shape of the inserter 21 and the shape of the sheet-like member 3 by being folded or bent.

[0035] 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.

[0036] The cover member 5 is preferably installed so as to be in contact with the insert 21. By installing the cover member 5 so as to be in contact with the insert 21, the opening 13C of the partition part 11 can be closed, and the fire resistance performance can be improved.

[0037] The cover member 5 is installed so as to form a gap 40 between it and the sheet-like member 3 (i.e., the partition portion), between it and the inserting body 21, or both. The presence of the gap 40 between the sheet-like member 3 and the cover member 5, or between the inserting body 21 and the cover member, allows the cover member 5 to be fixed with a margin for axial movement of the inserting body 21. Since the cover member 5 is fixed to the inserting body 21 with a margin, even if the inserting body 21 disposed 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 inserting body 21. By preventing the sheet-like member 3 and the cover member 5 from moving together with the inserting body 21, it is possible to prevent the sheet-like member 3 and the cover member 5 from shifting out of the compartment penetration portion 15. In other words, by adopting such a configuration, the sheet-like member 3 and the cover member 5 can be maintained and positioned appropriately 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.

[0038] 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 layer 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.

[0039] 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 used in the cover member 5 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 limits, flexibility is imparted to the cover member 5. Therefore, even if the cover member 5 has a fire-resistant material layer, the cover member 5 can be easily deformed and 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.

[0040] 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. In this case, the adhesive layer or the fireproof material layer may fix the cover member 5 to the insert 21 or the sheet-like member 3 together with the fastening materials 6A and 6B.

[0041] As described above, the cover member 5 is preferably a sheet that can be deformed so as to cover the sheet-like member 3. Furthermore, the cover member 5 is preferably flexible and thinner than the sheet-like member 3 so as to 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.

[0042] (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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] According to the configuration of the present embodiment, the gap 13E between the opening 13C of the compartment penetration 15 provided in the partition 11 and the insert 21 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, the compartment penetration treatment structure 10 can be provided with appropriate fire resistance. As described above, as shown in FIG. 1, the compartment penetration structure 10 is first installed by using the sheet-like member 3 to close the gap 13E between the opening 13C of the compartment penetration portion 15 and the insert 21. Next, the sheet-like member 3 is covered with the second cover portion 51 of the cover member 5, and the fastening material 6A is inserted into the partition portion 11 of the compartment penetration portion 15 through the second marks 53A, 53B, 53C, and 53D on the second cover portion 51 of the cover member 5, thereby securing the second cover portion 51 to the compartment penetration portion 15. Next, the first cover portion 50 of the cover member 5 is wrapped around the insert 21 and secured to the insert 21 by the fastening material 6B along the first mark 52 on the first cover portion 50. This construction is therefore easy and reliable, and it is possible to visually confirm whether the construction has been completed. 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.

[0056] Furthermore, in this embodiment, at least the cover member 5 and fastening materials 6A, 6B are exposed and visible from the outside. Also, it is preferable to position a portion of the sheet-like member 3 (the side surface of the sheet-like member 3 in the configurations of Figures 1 to 3) in a position where it is visible from the outside. And, no members other than the inserting body 21 are provided inside the compartment penetration part 15. Therefore, it is easy to check by visual inspection or photography that the compartment penetration processing material has been installed as specified. Also, it is less likely that installation will be forgotten.

[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 the compartment penetration treatment material is configured to include a tape-shaped member 4 and a cover member 5, as shown in Figures 8 and 9. 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.

[0058] [Tape-shaped member] 8 and 9, 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 at least a part of the gap 13E between the opening 13C and the insert 21.

[0059] 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.

[0060] 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 in 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. 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] The substrate used as the substrate layer 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.

[0065] 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.

[0066] 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.

[0067] The tape-shaped member 4 wound around the outer periphery of the inserter 21 may be in close contact with the inserter 21 and 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 around 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.

[0068] [Cover member] The cover member 5 is placed so as to cover the opening 13C of the compartment penetration part 15 provided in the partition part 11. Here, in this embodiment, as long as the cover member 5 is placed in a position that covers the opening 13C, another member may be placed between the cover member 5 and the opening 13C, and in this embodiment, the tape-shaped member 4 is placed between the cover member 5 and the opening 13C, and covers the opening 13C via the tape-shaped member 4. That is, the cover member 5 in this embodiment covers the tape-shaped member 4 and blocks a portion of the gap 13E that is not blocked by the tape-shaped member 4. With the above configuration, the entire gap 13E between the opening 13C of the compartment penetrating portion 15 and the inserting body 21 is blocked by the tape-shaped member 4 and the cover member 5. The cover member 5 is sheet-shaped and deformable, so that it can easily cover the tape-shaped member 4 and surround the inserting body 21 while adhering closely to the inserting body 21, thereby easily blocking a portion of the gap 13E that is not blocked by the tape-shaped member 4.

[0069] 9, the second cover portion 51 of the cover member 5 is disposed on the outer surface 11A. The second cover portion 51 of the cover member 5 is fastened to the compartment penetration portion 15 by inserting the fastening material 6A into the partition portion 11 of the compartment penetration portion 15 from the second marks 53A to 53D. The first cover portion 50 of the cover member 5 is arranged to cover the tape-shaped member 4. The first cover portion 50 of the cover member 5 surrounds the inserting body 21 so as to be in contact with it, and is fastened to the inserting body 21 by being restrained and fixed from the outside by the fastening material 6B along the first mark 52 attached to the first cover portion 50.

[0070] 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.

[0071] 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 described above, the compartment penetration structure 10 is installed by wrapping the tape-shaped member 4 around the insert 21 at least once and blocking at least a portion of the gap 13E between the opening 13C of the compartment penetration portion 15 and the insert 21 with the tape-shaped member 4. Next, the cover member 5 is installed to cover the tape-shaped member 4, and the fastening material 6A is inserted into the partition portion 11 of the compartment penetration portion 15 from the second mark on the second cover portion 51 of the cover member 5, thereby fixing the second cover portion 51 to the compartment penetration portion 15. Next, the first cover portion 50 of the cover member 5 is wrapped around the insert 21 and fixed to the insert 21 with the fastening material 6B along the first mark 52 on the first cover portion 50. This makes installation easy and reliable, and it is possible to visually confirm whether the installation has been completed. 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.

[0072] Furthermore, in this embodiment, at least the cover member 5 and fastening materials 6A, 6B are exposed and visible from the outside. The tape-shaped member 4 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 taking photographs to ensure that it has been installed as specified. Furthermore, forgetting to install it is less likely to occur.

[0073] [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 10 and 11. Below, the differences between the third embodiment and the first and second embodiments will be described. Furthermore, parts whose description will be 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 and second embodiments will be 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.

[0074] As shown in FIGS. 10 and 11, the sheet-like member 3 is placed so as to be in contact with the insert 21 and the partition portion 11. 10 and 11, 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 at least a part of the gap 13E between the opening 13C 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 and the cover member 5. 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 3, the tape-like member 4, and the cover member 5.

[0075] The cover member 5 is placed so as to cover the opening 13C of the compartment penetration part 15 provided in the partition part 11. Here, in this embodiment, as long as the cover member 5 is placed in a position that covers the opening 13C, another member may be placed between the cover member 5 and the opening 13C, and in this embodiment, the sheet-like member 3 and the tape-like member 4 are placed between the cover member 5 and the opening 13C, and the opening 13C is covered via the sheet-like member 3 and the tape-like member 4. That is, the cover member 5 in this embodiment covers the sheet-shaped member 3 and the tape-shaped member 4, and also closes a part of the gap 13E that is not closed by the sheet-shaped member 3 and the tape-shaped member 4. The cover member 5 is sheet-shaped and deformable, so that it can easily cover the sheet-shaped member 3 and the tape-shaped member 4, and surround the inserting body 21 while adhering closely to the inserting body 21, thereby easily blocking a portion of the gap 13E that is not blocked by the sheet-shaped member 3 and the tape-shaped member 4.

[0076] The cover member 5 can be configured to cover the surface 3A opposite to the surface 3B of the sheet-shaped member 3 that faces the partition portion 11. The cover member 5 can also be configured to cover the tape-shaped member 4. By using the cover member 5 to cover at least one of the surface 3A of the sheet-shaped member 3 and the tape-shaped member 4, it is possible to suppress the fall of residues from the sheet-shaped member 3 and the tape-shaped member 4, and improve the fire resistance of the compartment penetration portion 15.

[0077] 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.

[0078] 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 described above, the compartment penetration structure 10 is constructed by installing the sheet-like member 3 so as to block at least a portion of 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 at least once, and the tape-like member 4 is installed so as to block at least a portion of the gap 13E between the opening 13C of the compartment penetration portion 15 and the insert 21. Next, the cover member 5 is installed so as to cover both the sheet-like member 3 and the tape-like member 4, and the fastening material 6A is inserted into the partition portion 11 of the compartment penetration portion 15 from the second mark on the second cover portion 51 of the cover member 5, thereby fixing the second cover portion 51 to the compartment penetration portion 15. Next, the first cover portion 50 of the cover member 5 is wrapped around the insert 21, and the first cover portion 50 is fixed to the insert 21 with the fastening material 6B along the first mark 52 on the first cover portion 50. Therefore, the construction is easy and reliable, and it is possible to visually check whether the construction has been completed reliably. 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.

[0079] Furthermore, in this embodiment, at least the cover member 5 and fastening materials 6A, 6B are exposed and visible from the outside. It is also advisable to position the sheet-like member 3 and tape-like member 4 in a position where a portion of them can be seen 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 taking photographs to ensure that it has been installed as specified. It also becomes less likely that installation will be forgotten.

[0080] [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.

[0081] For example, in each of the above embodiments, the fastening materials 6A and 6B are fastened from the outside of the cover member 5, but they do not necessarily have to be fastened from the outside. For example, adhesive, pressure-sensitive adhesive, adhesive tape, or the like may be placed on the inside of the second cover portion 51 (i.e., on the partition portion 11 side) as a fastening material to fasten the second cover portion 51 of the cover member 5. In this case, the fastening material 6A that fastens the second cover portion 51 from the outside may be omitted or may be used in combination. Similarly, adhesive, pressure-sensitive adhesive, adhesive tape, or the like may be placed on the inside (i.e., the inserter side) of the first cover part 50 as a fastening material to fasten the first cover part 50 of the cover member 5 to the inserter. In this case, too, the fastening material 6B that fastens the first cover part 50 from the outside may be omitted or may be used in combination. The adhesives, pressure sensitive adhesives and adhesive tapes used as fastening materials are preferably made of non-combustible, semi-non-combustible or flame retardant materials, and flame retardants may be added to the adhesives, pressure sensitive adhesives and the like.

[0082] However, in the present invention, it is preferable to use fastening material 6A that fastens from the outside of second cover part 51. Similarly, it is preferable to use fastening material 6B that fastens from the outside of first cover part 50. By fastening the cover parts from the outside, the fastening material can be easily installed in the specified position, and it is also easy to visually confirm that the fastening material has been installed in the specified position.

[0083] Furthermore, in the present invention, as long as marks (first mark 52, second mark 53) are provided on the cover member 5, either the first mark 52 or the second mark 53 may be omitted, but it is preferable to provide at least the second mark 53. By providing the second mark 53, the second cover part 51 can easily position the fastening material 6A in an appropriate location, and by appropriately positioning the fastening material 6A, it is possible to effectively prevent gaps from occurring.

[0084] The cover member 5 may be provided with characters, text information, or graphics in addition to the first mark 52 and the second mark 53. For example, along with the first mark 52 and the second mark 53, the size of the opening to which the cover member 5 can be applied, the type of compartment penetration part, how to use the cover member, precautions, etc. may be written.

[0085] For example, in each of the above 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 fire-resistant materials and accessories. As specific examples, a modified example of the first embodiment is shown in Fig. 12, and a modified example of the second embodiment is shown in Fig. 13. As the fire-resistant material, for example, a block-shaped fire-resistant material 70 as shown in Figs. 12 and 13 is used, and the block-shaped fire-resistant material 70 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 70 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 70 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.

[0086] 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.

[0087] 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.

[0088] Furthermore, although the above-described embodiments also show an aspect in which at least one of the sheet-shaped member 3 and the tape-shaped member 4 is provided, both may be omitted. In the case in which both are omitted, the cover member 5 may have a fire-resistant material, but it is preferable that a fire-resistant material other than the sheet-shaped member 3 and the tape-shaped member 4 is disposed inside the cover member 5. For example, it is preferable that a fire-resistant material other than the sheet-shaped member 3 and the tape-shaped member 4 is disposed between the cover member 5 and the partition 11. The fire-resistant material may be disposed inside the compartment penetration part 15, for example, in the gap 13E between the opening 13C of the compartment penetration part 15 and the insert 21. Furthermore, the fire-resistant materials other than the sheet-shaped members 3 and the tape-shaped members 4 are preferably formed from a thermally expandable resin composition, but may also be fire-resistant putty or the like.
