Description

Technical Field

[0001] The present invention relates to a partition penetration treatment structure, a partition penetration treatment member, and a partition penetration treatment method used for a fireproof structure of a building.

Background Art

[0002] In buildings such as apartment houses, office buildings, and schools, partition penetration parts may be provided in partition parts such as walls to insert long insertion bodies such as cables and pipes. When a fire breaks out in any compartment, the partition penetration part is required to have a fireproof structure (fireproof structure) to prevent the spread of fire to other compartments. The partition part generally consists of two wall parts, and a hollow wall with a hollow part between the wall parts is common.

[0003] A method of making the partition penetration part a fireproof structure is known, for example, a method of filling a refractory putty into the gap between a long insertion body and a through hole (see, for example, Patent Document 1). In addition, a method of filling the gap between the insertion body and the through hole with an amorphous filler such as a refractory pack in which a refractory putty is packed inside a bag has been proposed (see, for example, Patent Document 2). When using an amorphous filler, it is common to use a product in which a refractory pack or sleeve in which a predetermined amount of refractory putty is packed inside a bag is made into a kit. In addition, in order to facilitate the installation of the above-mentioned refractory putty and amorphous filler and improve the fire resistance and fire extinguishing properties, a cylindrical insertion member may be disposed in the partition penetration part. The insertion member exhibits fire resistance performance and fire extinguishing performance by being disposed at an appropriate position in the partition penetration part. The insertion member has an elastic protrusion, and the elastic protrusion protrudes outside the through hole and can be easily installed in the through hole by hanging outside the through hole (see, for example, Patent Document 3).

[0005] However, long objects such as cables and pipes are passed through the inside of the through member, and if the objects are moved after the through member is installed, the through member and the fire-resistant putty inside the through member may shift from their proper positions. Furthermore, external forces such as earthquakes can also cause the through member and other objects to shift from their proper positions. In this way, the shifting of the through member and the fire-resistant putty inside the through member from their proper positions makes it difficult to achieve the fire resistance and fire extinguishing performance desired for a fire-resistant structure of a compartment penetration.

[0006] Therefore, in view of the above problems, the present invention aims to provide a compartment penetration treatment structure, a compartment penetration treatment member, and a compartment penetration treatment method that enable members used in the fire-resistant structure of a building to efficiently exhibit fire resistance and fire extinguishing performance, and that suppress displacement of insertion members used in the fire-resistant structure of a building.

[0010] Hereinafter, the present invention will be described in more detail using embodiments.

[0011] [First Embodiment] As shown in FIG. 1, the partition penetration processing structure according to the first embodiment of the present invention is a partition penetration processing structure having a fireproof structure for a partition penetration portion 15 formed in a partition portion 11 of a building and through which a long insertion body 21 is inserted. The partition penetration processing member used in the partition penetration processing structure according to the first embodiment of the present invention includes an insertion member 3, a locking member 4, and a covering member 5.

[0012] The partition portion 11 in the partition penetration processing structure of the present invention is a member that partitions between compartments (the first compartment A and the second compartment B) on the wall surface of a building, and has a partition penetration portion 15 that penetrates from one outer surface 11A side of the partition portion 11 to the other outer surface 11B side. The partition portion 11 shown in FIG. 1 is a hollow wall and is composed of two wall materials (partition materials) 12A and 12B arranged with an interval (hollow portion 13) therebetween. Therefore, the partition penetration portion 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 therebetween. And the outer surface of one wall material 12A constitutes the outer surface 11A of the partition portion 11, and the outer surface of the other wall material 12B constitutes the outer surface 11B of the partition portion 11. The through holes 13A and 13B may have a circular, elliptical, or a shape approximating these so that when the insertion member 3 described later is inserted, the outer peripheral surface of the insertion member 3 can conform to the shape of the inner peripheral surfaces of the through holes 13A and 13B. Note that the through holes 13A and 13B constitute the openings 13C and 13D of the partition penetration portion 15 provided in the partition portion 11 on the outer surfaces 11A and 11B respectively.

[0013] 〔Insertion member〕 The insertion member 3 is disposed in the partition penetration portion 15 in a sleeve shape and is inserted into the partition penetration portion 15 so that the insertion body 21 passes through the inside of the sleeve. Here, the sleeve-shaped insertion member 3 passes from one through hole 13A to the other through hole 13B in the partition penetration portion 15. The insertion member 3 can prevent the hollow portion 13 and the outside of the partition portion 11 from communicating. The insertion member 3 is either sleeve-shaped or can be deformed into a sleeve shape. Here, an insertion member 3 that can be deformed into a sleeve shape means that a sheet-shaped insertion member 3 is deformed into a sleeve shape by bringing its ends facing each other and then inserted into the partition penetration 15. The sheet-shaped insertion member 3 is not limited to being sheet-shaped from the beginning, but also includes those that have been unwound from a roll into a sheet shape. However, when deforming the insertion member 3 into a sleeve shape, the ends of the sheet-shaped insertion member 3 are not limited to butting together, but may be made into a sleeve shape by overlapping the ends. Because the insertion member 3 can be deformed into a sleeve shape, the size of the insertion member 3 can be adjusted to match the size of the through holes 13A and 13B at the construction site, so it can accommodate partition penetration 15 of various sizes. The thickness of the sheet-shaped or roll-shaped insertion member 3 is not particularly limited, but for example, it is 0.01 to 10 mm, preferably 0.05 to 5 mm. The insertion member 3 should be flexible so that it can be deformed into a sleeve shape.

[0014] The insertion member 3 is made of a fire-resistant material. Preferably, the fire-resistant material is a thermally expandable material that expands when heated. The thermally expandable material prevents the spread of fire by expanding during a fire. The thermally expandable member is formed from a thermally expandable resin composition. The thermally expandable resin composition contains a resin component and a thermally expandable material. By forming the insertion member 3 from a thermally expandable resin composition containing a resin component, the formation and deformation of the curved shape of the insertion member 3 becomes easier, and it can be made into a sleeve shape as described above. Examples of thermally expandable materials include thermally expandable inorganic materials. By using thermally expandable inorganic materials, they expand appropriately when heated by fire, and the mechanical strength of the expanded residue after expansion is excellent, making it easier to improve fire resistance. Note that the thermally expandable materials referred to here do not expand substantially through molding or other processes described later, and thermally expandable resin compositions maintain their thermal expandability in thermally expandable components.

[0015] The expansion initiation temperature of a 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. Setting it below these lower limits prevents the thermally expandable material from expanding unintentionally due to heating other than fire. Setting it below the upper limit makes it easier to reliably expand the thermally expandable material due to heating from a fire. Furthermore, the expansion initiation temperature of a thermally expandable material can be measured by heating a predetermined amount (e.g., 100 mg) of the thermally expandable material at a constant heating rate (e.g., 10°C / min) and measuring the temperature at which the normal force begins to rise. The measuring device can be any device that allows for temperature control and measurement of stress in the normal direction; for example, a rheometer can be used. The thermal expansion ratio of the thermally expandable member is preferably 3 times or more, and preferably 10 times or more. The upper limit of the expansion ratio is not particularly limited, but for example, it is 50 times. The expansion ratio can be calculated by supplying the thermally expandable member to an electric furnace, heating it at 600°C for 30 minutes, measuring the thickness of the test piece, and then dividing it by (thickness of the test piece after heating) / (thickness of the test piece before heating).

[0016] The following describes in detail a thermally expandable resin composition when the thermally expandable material is thermally expandable graphite. Examples of resin components in a thermally expandable resin composition include thermoplastic resins, thermosetting resins, and elastomers. Examples of thermoplastic resins include polyvinyl chloride (PVC), chlorinated polyvinyl chloride resin (CPVC), fluororesins, polyphenylene ether, modified polyphenylene ether, polyphenylene sulfide, polycarbonate, polyetherimide, polyetheretherketone, polyarylate, polyamide, polyamideimide, polybutadiene, polyimide, acrylic resin, polyacetal, polyamide, polyethylene (PE) and polypropylene (PP), polyolefins such as ethylene vinyl acetate (EVA), ethylene-propylene-diene copolymer (EPDM), polyesters such as 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 curable resins include epoxy resins, phenolic resins, melamine resins, urea resins, unsaturated polyester resins, alkyd resins, polyurethanes, and thermosetting polyimides.

[0017] 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 of thermoplastic elastomers include 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 heat-expandable resin composition may be one type or a combination of two or more types.

[0018] The heat-expandable resin composition may contain a plasticizer. Plasticizers are preferably used when the resin component is a thermoplastic resin such as polyvinyl chloride resin. Specific examples of plasticizers include phthalate ester plasticizers such as di-2-ethylhexyl phthalate (DOP), dibutyl phthalate (DBP), diheptyl phthalate (DHP), and diisodecyl phthalate (DIDP); fatty acid ester plasticizers such as adipate esters such as di-2-ethylhexyl adipate (DOA), diisobutyl adipate (DIBA), and dibutyl adipate (DBA), and adipate polyester; epoxidized ester plasticizers such as epoxidized soybean oil; trimellitate ester plasticizers such as tory 2-ethylhexyl trimellitate (TOTM) and triisononyl trimellitate (TINTM); phosphate ester plasticizers such as trimethyl phosphate (TMP) and triethyl phosphate (TEP); and process oils such as mineral oil. The plasticizer may be one type or a combination of two or more types. When a thermally expandable resin composition contains a plasticizer, the amount of 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 plasticizer is above these lower limits, the moldability tends to be good, and when it is below the upper limits, the molded article is given appropriate strength.

[0019] The total content of resin components and plasticizers is preferably 10% to 90% by mass, more preferably 25% to 80% by mass, and even more preferably 40% to 70% by mass, based on the total amount of the resin composition. Setting the content above these lower limits improves the moldability of the thermally expandable member. It also ensures flexibility, making it easier to deform into a sleeve shape. Furthermore, setting the content below the upper limit allows for the incorporation of sufficient amounts of components such as thermally expandable graphite and inorganic fillers. Note that the total content of resin components and plasticizers refers to the combined content of both resin components and plasticizers if both are present, and to the content of resin components alone if no plasticizer is present.

[0020] Thermally expandable graphite is a conventionally known substance, produced by treating powders of natural flake graphite, pyrolysis graphite, quiche graphite, etc., with inorganic acids such as concentrated sulfuric acid, nitric acid, and selenic acid, and strong oxidizing agents such as concentrated nitric acid, perchloric acid, perchlorate, permanganate, dichromate, and hydrogen peroxide to generate graphite intercalation compounds. The resulting thermally expandable graphite is a crystalline compound that maintains the layered structure of carbon. The thermally expandable graphite used in this invention may also be obtained by neutralizing thermally expandable graphite obtained by acid treatment with ammonia, aliphatic lower amines, alkali metal compounds, alkaline earth metal compounds, etc. Examples of aliphatic lower amines include monomethylamine, dimethylamine, trimethylamine, ethylamine, propylamine, and butylamine. Examples of alkali metal compounds and alkaline earth metal compounds include hydroxides, oxides, carbonates, sulfates, and organic acid salts of potassium, sodium, calcium, barium, magnesium, and other metals.

[0021] The particle size of the thermally expandable graphite is not particularly limited, but a range of 20 to 200 mesh is preferred. If the particle size is above the lower limit, the degree of expansion of the graphite tends to increase, resulting in good foaming properties. If the particle size is below the upper limit, the dispersibility when kneading with resin improves, and moldability is enhanced.

[0022] 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 per 100 parts by mass of the resin component. When the content of thermally expandable graphite is 3 parts by mass or more, good thermal expandability is achieved. Furthermore, when the content is 300 parts by mass or less, good moldability is achieved, and the surface properties, mechanical properties, and flexibility 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.

[0023] The thermally expandable resin composition may further contain an inorganic filler. The inorganic filler is not particularly limited as long as it is an inorganic filler commonly used in thermally expandable resin compositions. Specifically, 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, dohnite, hydrotalcite, calcium sulfate, barium sulfate, gypsum fiber, calcium silicate, talc, clay, myca, montmorillonite, bentonite, activated clay, ceviolite, 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 zirconia titanate, aluminum borate, molybdenum sulfide, silicon carbide, stainless steel fiber, zinc borate, various magnetic powders, slag fiber, fly ash, dewatered sludge, etc. One or more types of inorganic fillers may be used. When an inorganic filler is included, the amount of 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.

[0024] The thermally expandable resin composition used in the present invention may contain various additive components as needed, as long as the objectives of the present invention are not impaired. The type of additive component is not particularly limited, and various additives can be used. Examples of such additives include lubricants, shrinkage inhibitors, nucleating agents, colorants (pigments, dyes, etc.), UV absorbers, antioxidants, anti-aging agents, reinforcing agents, flame retardant aids, antistatic agents, surfactants, vulcanizing agents, and surface treatment agents. The amount of additive component can be appropriately selected within a range that does not impair moldability, etc. Additive components may be used individually or in combination of two or more types.

[0025] The thermally expandable resin composition used in the present invention can be obtained by mixing a resin, a thermally expandable inorganic substance, and an optional component using known equipment such as a bead mill, Banbury mixer, kneader mixer, kneading roll, lycainette, and planetary agitator.

[0026] [Locking member] The locking member 4 contacts the partition portion 11 and at least one end 30 of the insertion member 3, fixing the position of the insertion member 3. The locking member 4 is locked to the outer circumference of the through hole 13A (i.e., one of the openings 13C) on its outer surface 11A, so that one end 30 of the insertion member 3 is fixed to the partition portion 11. The shape of the locking member 4 is not particularly limited and can be, for example, block-shaped, columnar, or point-shaped.

[0027] The locking member 4 is not particularly limited as long as it is made of a material capable of locking the partition 11 and the insertion member 3. Examples include fire-resistant materials, foams, putty materials, and caulking materials, and may also be composite materials made by combining two or more of these. The fire-resistant material is not particularly limited as long as it is a material with fire resistance, but it is preferably a fire-resistant material formed from a heat-expandable resin composition containing the above-mentioned heat-expandable material. Details of the fire-resistant material are as described above. Examples of foams include foamed polyethylene, foamed polypropylene, foamed polystyrene, and foamed polyurethane. Examples of putty materials and caulking materials include those made by blending synthetic resin materials such as silicone resins, acrylic resins, and urethane resins as the main component with fillers and flame retardants. If the locking member 4 is made of the same material as the insertion member 3, it may be formed integrally with the insertion member 3. If it is made of the same or different material as the insertion member 3, it is provided separately so as to be in contact with the partition 11 and the insertion member 3.

[0028] As shown in Figure 2, it is preferable that the locking member 4 be provided in such a way as to close the gap 40 that is formed between the partition portion 11 and the insertion member 3. Specifically, as shown in Figure 2(a), the locking member 4 can be positioned to cover the gap 40 between the partition portion 11 and the insertion member 3, thereby closing the gap 40. Also, as shown in Figure 2(b), the locking member 4 can be positioned to fit into the gap 40 between the partition portion 11 and the insertion member 3, thereby closing the gap 40. In this way, by closing the gap 40 formed between the partition portion 11 and the insertion member 3 with the locking member 4, the fire resistance of the partition penetration portion 15 can be improved. When the locking member 4 is, for example, a fire-resistant material, foam, putty, and caulking material, it is preferable to have the configuration shown in Figure 2(a). Also, when the locking member 4 is a putty and caulking material, it is preferable to have the configuration shown in Figure 2(b) because it is easy to insert into the gap 40. Furthermore, the locking member 4 may be a combination of a fire-resistant material or foam and a putty or caulking material, or a combination of all of them, and in that case as well, it is preferable to insert the putty or caulking material into the gap 40.

[0029] [Enveloping part] The covering portion 5 is a sheet-like material provided on at least one end side of the insertion member 3, covering the gap 50 between the opening 13D of the partition penetration portion 15 provided in the partition portion 11 and the insertion body 21. Means for providing the covering portion 5 on at least one end side 31 of the insertion member 3 include, for example, means of fixing it by known fixing means such as adhesives, adhesives and adhesive tapes. Here, the adhesives, adhesives and adhesive tapes are preferably non-combustible materials, semi-non-combustible materials or flame-retardant materials, and it is preferable to incorporate flame retardants into the adhesives, adhesives, etc.

[0030] As shown in Figure 1, the covering portion 5 surrounds the insertion body 21, with the portion covering the opening 13D of the compartment penetration portion 15 enclosing the insertion body 21, and is fixed to the insertion body 21 by a string-like member 22 wrapped around it from the outside. The string-like member 22 can be any bendable member, and is preferably a wire member including a wire. The wire member may be a metal wire alone, a resin-coated wire made by coating a metal wire with resin such as Nejiriko (registered trademark), or a wire and fiber intertwined, such as a molding. Using a wire member allows the covering portion 5 to be fixed to the insertion body 21 simply by twisting or turning it.

[0031] The covering portion 5 is fixed with a margin of error against the axial movement of the insertion body 21. Because the covering portion 5 is fixed to the insertion body 21 with a margin of error, even if the insertion body 21, which is positioned inside the insertion member 3, is moved axially after the insertion member 3 has been installed, the margin of error of the covering portion 5 prevents the insertion member 3 from moving together with the insertion member 21, thereby suppressing the insertion member 3 from shifting away from the compartment penetration portion 15. In other words, with this configuration, the insertion member 3 can be maintained in the appropriate position within the compartment penetration portion 15, and the fire resistance of the compartment penetration portion 15 can be maintained. Configurations that allow the covering portion 5 to be fixed with a margin of error against the axial movement of the insertion body 21 include, for example, a configuration in which at least a part of the covering portion 5 is made of a flexible or stretchable material that can be bent or curved, and a configuration in which at least a part of the covering portion 5 is fixed to the insertion body 21 with some slack.

[0032] The covering portion 5 should preferably be 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 covering portion 5 include metal foil such as aluminum foil, glass cloth, and 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 covering portion 5 is, for example, 0.01 to 1 mm, preferably 0.05 to 0.5 mm.

[0033] The following describes a specific example of a partition penetration processing method using a partition penetration processing member equipped with a sleeve-shaped insertion member 3. As shown in Figure 3, a pre-formed sleeve-shaped insertion member 3 is prepared. Furthermore, a covering portion 5 is provided on one end 31 of the insertion member 3.

[0034] As shown in Figure 3, after the sleeve-shaped insertion member 3 is positioned, one end 30 of the insertion member 3 extends outward from the through hole 13A, and the locking member 4 is positioned so as to be in contact with the extended insertion member 3 and the outer circumference of the through hole 13A. The position of the insertion member 3 is fixed by the position of the locking member 4. The locking member 4 may be made of fire-resistant material, foam, putty, or caulking material. When fire-resistant material or foam is used as the locking member 4, it can be prepared in advance in an annular shape and installed after the insertion member 3 is positioned in the partition penetration 15. When putty or caulking material is used as the locking member 4, it can be applied to the insertion member 3 after the insertion member 3 is positioned in the partition penetration 15.

[0035] As shown in Figure 3, the sleeve-shaped insertion member 3 is placed in the partitioned penetration portion 15, and then a covering portion 5 provided at one end 31 of the insertion member 3 extends outward from the through hole 13B. The covering portion 5 extending from the through hole 13B is bent or folded as appropriate to reduce its diameter and surrounds the outer circumference of the insertion body 21 while closely fitting it. Then, a string-like member 22 is wrapped around the surrounding portion of the covering portion 5 and fixed to the insertion body 21 by the string-like member 22, so that one opening 13D of the partitioned penetration portion 15 is covered by the covering portion 5.

[0036] The following describes a specific example of a partition penetration processing method using a partition penetration processing member equipped with a sleeve-shaped insertion member 3. The sleeve-shaped insertion member 3 is sheet-like, and as shown in Figure 4, a locking member 4 is laminated on one end 30 of one side. A covering portion 5 is also provided on one end 31 of the insertion member 3. In the configuration shown in Figure 4, the locking member 4 is preferably made of foam or fire-resistant material. It is also preferable that the ends of the locking members 4 are butted together.

[0037] The sleeve-shaped insertion member 3, as shown in Figure 5, deforms into a sleeve shape to conform to the shape of the inner circumferential surface of the through holes 13A and 13B that constitute the partitioned penetration portion 15. That is, the insertion member 3 is preferably shaped into a sleeve so that its outer circumferential surface conforms to the shape of the inner circumferential surface of the through holes 13A and 13B. Since the shape of the inner circumferential surface of the through holes 13A and 13B is generally a circle, an ellipse, or a shape similar thereto, the insertion member 3 is preferably rolled up into a sleeve shape, and is preferably shaped like a circle, an ellipse, or a shape similar thereto. Furthermore, when the insertion member 3 is formed into a sleeve shape, its ends are butted together, and in this case, the ends may be bonded together with an adhesive, adhesive, and adhesive tape. Here, the adhesive, 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 preferable to incorporate a flame retardant into the adhesive, adhesive, etc. The adhesive tape comprises a base material and an adhesive layer provided on one side of the base material, and it is preferable that the base material and the adhesive layer each be made of a non-combustible material, a semi-non-combustible material, or a flame-retardant material. However, when the insertion member 3 is formed into a sleeve shape, the ends are not limited to butting together, and the ends may be overlapped to form a sleeve shape.

[0038] After the sleeve-shaped insertion member 3 is placed in the partitioned penetration portion 15, the covering portion 5 provided at one end 31 of the insertion member 3 extends outward from the through hole 13B. The covering portion 5 extending from the through hole 13B is bent or folded as appropriate to reduce its diameter and surrounds the outer circumference of the insertion body 21 while closely fitting in. Then, a string-like member 22 is wrapped around the surrounding portion of the covering portion 5 and fixed to the insertion body 21 by the string-like member 22, so that one opening 13D of the partitioned penetration portion 15 is covered by the covering portion 5. If a gap is formed between the partition 11 and the insertion member 3 after the sleeve-shaped insertion member 3 has been placed in the partition penetration 15, it is preferable to further form a locking member 4 using putty and caulking material to close the gap.

[0039] According to the partition penetration treatment structure of the first embodiment of the present invention, the insertion member 3 prevents the hollow portion 13 from communicating with the outside of the partition portion 11, and since one opening 13D of the partition penetration portion 15 is covered by the covering portion 5, it is possible to prevent one opening 13C of the partition penetration portion 15 from communicating with the other opening 13D. Therefore, the partition penetration treatment structure of the first embodiment can provide the partition penetration portion 15 with an appropriate fire-resistant structure. Furthermore, according to the partition penetration processing structure of the first embodiment of the present invention, the locking member 4 and the covering portion 5 can suppress displacement of the insertion member 3 in the partition penetration portion 15, thereby maintaining the fire resistance of the partition penetration portion 15.

[0040] [Second Embodiment] The difference between the second embodiment and the first embodiment is that, as shown in Figure 6, the laminated structure of the insertion member 3, locking member 4, and covering portion 5 of the partition penetration processing member is different. The differences between the second embodiment and the first embodiment will be explained below. In the following, even in descriptions of different embodiments, the same reference numerals will be used for members having the same configuration.

[0041] As shown in Figure 6, the partition penetration processing member according to this embodiment has a covering portion 5 laminated on one surface of the insertion member 3. The covering portion 5 is laminated so as to extend from one end 31 of the insertion member 3. The locking member 4 is then laminated on the covering portion 5 that is laminated on the end 30 side of the insertion member 3. In this embodiment, by laminating the insertion member on the covering portion 5, the insertion member 3 can be easily manufactured by forming it on the covering portion 5 by applying a heat-expandable resin composition or the like. As shown in Figure 7, the sleeve-shaped insertion member 3 deforms into a sleeve shape to conform to the shape of the inner circumferential surface of the through holes 13A and 13B that constitute the partitioned penetration portion 15.

[0042] After the sleeve-shaped insertion member 3 is placed in the partitioned penetration portion 15, the covering portion 5 provided at one end 31 of the insertion member 3 extends outward from the through hole 13B. The covering portion 5 extending from the through hole 13B is bent or folded as appropriate to reduce its diameter and surrounds the outer circumference of the insertion body 21 while closely fitting in. Then, a string-like member 22 is wrapped around the surrounding portion of the covering portion 5 and fixed to the insertion body 21 by the string-like member 22, so that one opening 13D of the partitioned penetration portion 15 is covered by the covering portion 5. If a gap is formed between the partition 11 and the insertion member 3 after the sleeve-shaped insertion member 3 has been placed in the partition penetration 15, it is preferable to further form a locking member 4 using putty and caulking material to close the gap.

[0043] [Third Embodiment] The difference between the third embodiment and the first embodiment is that, as shown in Figure 8, the locking members 4 (4A, 4B) are in contact with both ends of the partition 11 and the insertion member 3. The differences between the third embodiment and the first embodiment will be explained below. In the following, even in descriptions of different embodiments, the same reference numerals will be used for members having the same configuration.

[0044] In this embodiment, as shown in Figure 8, the partition penetration processing structure has a locking member 4A attached to one end 13A of the partition 11 and the insertion member 3, and a locking member 4B attached to the other end 13B. The locking members 4A and 4B may be made of the same material or of different materials. The locking members 4A and 4B are in contact with the partition portion 11 and both ends 13A and 13B of the insertion member 3, and the movement of the insertion member 3 is suppressed at both ends 13A and 13B of the partition portion 11. The locking members 4A and 4B can close any gaps that may form between the partition 11 and the insertion member 3 at both ends 13A and 13B.

[0045] In this embodiment, as shown in Figure 9, for example, a locking member 4A is laminated on one end 30 side of one surface of the insertion member 3, and a locking member 4B is laminated on the other end 31 side. In addition, a covering portion 5 is provided on the end 31 side of the insertion member 3. Furthermore, as shown in Figure 10, for example, in the partition penetration processing member according to this embodiment, a covering portion 5 is laminated on one surface of the insertion member 3. The covering portion 5 is laminated so as to extend from one end 31 of the insertion member 3. A locking member 4A is laminated on the covering portion 5 laminated on the side of the one end 30 of the insertion member 3, and a locking member 4B is laminated on the covering portion 5 laminated on the side of the other end 31.

[0046] A specific example of a partition penetration processing method using the partition penetration processing member according to this embodiment will be described below. As shown in Figure 11, the sleeve-shaped insertion member 3 deforms into a sleeve shape to conform to the shape of the inner circumferential surface of the through holes 13A and 13B that constitute the partitioned penetration portion 15. At this time, it is necessary to reduce the diameter of the insertion member 3 to the extent that the locking member 4B can pass through the through holes 13A and 13B.

[0047] After the sleeve-shaped insertion member 3 is placed in the partitioned penetration portion 15, the covering portion 5 provided at one end 31 of the insertion member 3 extends outward from the through hole 13B. The covering portion 5 extending from the through hole 13B is bent or folded as appropriate to reduce its diameter and surrounds the outer circumference of the insertion body 21 while closely fitting in. Then, a string-like member 22 is wrapped around the surrounding portion of the covering portion 5 and fixed to the insertion body 21 by the string-like member 22, so that one opening 13D of the partitioned penetration portion 15 is covered by the covering portion 5. If a gap is formed between the partition 11 and the insertion member 3 after the sleeve-shaped insertion member 3 has been placed in the partition penetration 15, it is preferable to further form locking members 4A and 4B using putty and caulking materials to close the gap.

[0048] The locking member 4A or the locking member 4B may be provided in addition after the insertion member 3 is placed in the partition penetration 15. If the locking member 4A or the locking member 4B is provided in addition after the partition penetration 15 is placed, the insertion member 3 may be a sleeve-shaped one from the start.

[0049] According to the partition penetration processing structure of the third embodiment of the present invention, the locking members 4A and 4B are provided in contact with both ends 13A and 13B of the partition 11 and the insertion member 3, thereby further suppressing the movement of the insertion member 3 on both ends 13A and 13B of the partition 11, and maintaining the fire resistance of the partition penetration 15. Furthermore, even if a gap is formed between the partition portion 11 and the insertion member 3 at both ends 13A and 13B, the presence of locking members 4A and 4B prevents the gap from forming on both sides, thereby improving the fire resistance of the partition penetration portion.

[0050] [Fourth Embodiment] The fourth embodiment differs from the first embodiment in that, as shown in Figure 12, the sleeve-shaped insertion member 3 has multiple notches 41B formed in it. The differences between the fourth embodiment and the first embodiment will be explained below. In the following description, even in different embodiments, the same reference numerals will be used for members having the same configuration.

[0051] In the fourth embodiment, as shown in Figure 12, a plurality of notches 41B are formed in the sleeve-shaped insertion member 3. Each notch 40B is inserted from one end 41A of the sheet-like insertion member 3 to the middle of the insertion member 3. Because the insertion member 3 has notches 40B, as shown in Figure 1, one end 41A is folded outward to form a flange-shaped locking member 4. The locking member 4 is locked on the outer surface 11A to the outer circumference of the through hole 13A (i.e., one of the openings 13C) or inside the through hole 13A, and the one end 30 side of the insertion member 3 is fixed to the partition 11. Therefore, the insertion member 3 inserted into the partition penetration 15 is securely fixed to the desired position in the partition penetration 15.

[0052] [Other embodiments] In the above description, the first to fourth embodiments were shown as partition penetration processing structures, but the first to fourth embodiments may be combined as appropriate. In other words, each of the embodiments shown in the above description may be combined as appropriate, or all of them may be combined. Furthermore, the partition penetration processing structure is not limited to the embodiments shown above, and any configuration is acceptable as long as a partition penetration processing member comprising an insertion member, a locking member, and a covering portion is used.

[0053] For example, in each of the above embodiments, the covering portion is fixed to the insert body by a string-like member, but it may be fixed by something other than a string-like member, for example, by an adhesive layer or a fire-resistant material. The adhesive layer or fire-resistant material may be pre-laminated on the inside of the covering portion that is in contact with the insert body or on the entire covering portion. The adhesive layer may consist of an adhesive layer alone, or it may be a double-sided adhesive tape having an adhesive layer on both sides of the base material. The fire-resistant material may be formed from the above-mentioned heat-expandable resin composition, but for example, an uncured or solvent-diluted heat-expandable resin composition may be applied to the covering portion, and the uncured or undried heat-expandable resin composition may be cured and dried in contact with the insert body to fix the covering portion and the insert body via the fire-resistant material. Furthermore, the covering portion may be fixed by a putty-like mixture which is a resin composition containing at least one inorganic material selected from among hydroxides such as aluminum hydroxide and magnesium hydroxide, carbon oxides such as calcium carbonate and magnesium carbonate, oxides such as magnesium oxide, phosphorus, ammonium polyphosphate, aluminum phosphite and phosphorus compounds, sulfides such as calcium sulfate, lead sulfate and barium sulfate, bentonite, vermiculite, mica, boron nitride, alumina, etc. Furthermore, the covering portion may be secured by adhesive tape wrapped around it from the outside. The adhesive tape should preferably be a single-sided adhesive tape, which has a base material and an adhesive layer on one side of the base material. Details of the base material and adhesive layer are as described above.

[0054] Furthermore, in each of the above embodiments, the insertion member is made of fire-resistant material, but it may also be made of non-combustible material. Non-combustible material for insertion members refers to those specified in the Building Standards Act and the Enforcement Order of the Building Standards Act. Examples of non-combustible material for insertion members include mortar, metal pipes such as steel sleeves, inorganic fibers and their molded products. [Explanation of Symbols]
