Description

[Technical Field]

[0001] The present invention relates to a fire-resistant structure formed in a partition of a building or the like. [Background technology]

[0002] In buildings such as apartment complexes, office buildings, and schools, compartment penetrations are often installed in partitions such as walls, ceilings, and floors to allow long objects such as cables and pipes to pass through. Compartment penetrations are required to be constructed with fire prevention measures (fire-resistant construction) to prevent the fire from spreading to other compartments in the event of a fire breaking out in one compartment.

[0003] One known method for making a compartment penetration fireproof is to fill the gap between the long insert and the penetration hole with an unshaped filler such as fireproof putty (see, for example, Patent Document 1). However, when unshaped filler is used to fireproof a partition material with an opening, it cannot be said that the workability is high, and variations can occur depending on the worker, which can result in insufficient fire resistance, and the fire resistance can also deteriorate over time. External forces such as earthquakes can also cause irregular fillers such as fire-resistant putty to shift from their proper positions. This makes it difficult for the fire-resistant structure of the compartment penetration to achieve the fire resistance performance desired. Furthermore, when amorphous filler is used to fireproof a partition material with an opening, it is difficult to confirm whether the amorphous filler has completely filled the opening, and if the filling is insufficient, it becomes difficult to achieve the fire resistance performance desired for the fire-resistant treatment structure of the compartment penetration part.

[0009] The present invention will be described in more detail below using embodiments.

[0010] [First embodiment] The partition material 100 in the fire-resistant structure according to the first embodiment of the present invention is a component that separates compartments (a first compartment A and a second compartment B) on the wall of a building, as shown in Fig. 1. Examples of the partition material 100 include gypsum board, ALC board, extruded cement board, lightweight wood wool cement board, wood chip cement board, metal sandwich panel, calcium silicate board, slate board, concrete, brick, glass, and metal plate (e.g., aluminum, iron), etc. The partition material 100 is provided with openings 101 for passing through inserts 21 (21A, 21B) such as cables and pipes. The shape of the openings 101 is not particularly limited as long as it allows the inserts to pass through, and may be, for example, circular, elliptical, rectangular, or any shape similar to these. The openings 101 form compartment penetrations in the partition material 100, and the compartment penetrations are treated by being blocked with a compartment penetration treatment material. In this embodiment, the compartment penetration treatment material is composed of a first frame 8, a sheet-like member 3, a fire-resistant filler 5, etc., which will be described later.

[0011] As shown in FIGS. 1 and 2, the fireproof structure according to the first embodiment of the present invention provides a fireproof partition section of a building using a partition material 100 having an opening 101 formed therein. An insert 21 is inserted into the partition material 100 having the opening 101 formed therein, and a fireproof material is arranged so as to close the gap between the first frame body 8 and the insert 21. The fireproof material is a member that closes at least a portion of the gap between the first frame body 8 and the insert 21, and constitutes at least a portion of the compartment penetration material, and in this embodiment is constituted by a sheet-like member 3 and a fireproof filler material 5, which will be described later. In the fireproof structure, it is preferable that any of the members that constitute the fireproof material contain fireproof material.

[0012] [First frame] As shown in FIGS. 1 and 2, the first frame 8 is cylindrical and has an insert 21 inserted therethrough. The first frame 8 is disposed so as to contact the inner circumferential surface of the opening 101 of the partition material 100 and to span at least from one end to the other of the partition material 100. The ends of the first frame 8 need only extend to at least both ends of the opening 101 (i.e., both outer surfaces of the partition material 100), and may extend beyond the outer surface of the partition material 100. The first frame 8 shown in FIGS. 1 and 2 has a length equivalent to the thickness of the partition material 100, and has a length that is just long enough to span from one end of the partition material 100 to the other (from outer surface to outer surface). From the viewpoint of improving fire resistance, the first frame 8 preferably contacts the inner circumferential surface of the opening 101 from end to end. The first frame 8 is made of metal, resin, paper, or the like. The first frame 8 may be sleeve-shaped and insertable into the opening 101. For example, the first frame 8 may be a metal sleeve such as a steel sleeve formed from steel, resin, or paper, or a resin sleeve or a paper sleeve. Alternatively, the first frame 8 may be a sleeve-shaped sheet made of a metal, resin, or paper sheet rolled up and fixed as appropriate. The first frame 8 may also be a single frame formed by assembling two or more members. The first frame 8 may also be formed in a sleeve shape by facing the ends of sheet-like fire-resistant material or by overlapping the ends of sheet-like fire-resistant material to form a joint 80. The first frame 8 formed from a sleeve-shaped fire-resistant material or various sheets allows the internal space through which the insert 21 is inserted to be adjustable. When a sheet-like fire-resistant material or various sheets is formed into a sleeve shape, the joint 80 between the ends may be bonded with an adhesive, pressure-sensitive adhesive, adhesive tape, or the like. The adhesive, pressure-sensitive adhesive, and adhesive tape are preferably made of a non-combustible material, a quasi-non-combustible material, or a flame-retardant material, and the adhesive, pressure-sensitive adhesive, or the like may be blended with a flame retardant. The adhesive tape includes a substrate and an adhesive layer provided on one side of the substrate, and the substrate and adhesive layer may each be made of a non-combustible material, a quasi-non-combustible material, or a flame-retardant material. The thickness of the first frame 8 is not particularly limited, but is, for example, 0.2 to 10 mm, and preferably 0.5 to 6 mm.

[0013] The first frame body 8 is formed in a sleeve shape so as to fit the shape of the inner peripheral surface of the opening 101. That is, the first frame body 8 is formed in a sleeve shape so that its outer peripheral surface follows the shape of the inner peripheral surface of the opening 101, and is disposed so that the outer peripheral surface of the first frame body 8 comes into contact with the inner peripheral surface of the opening 101. The shape of the inner surface of the opening 101 is generally a circle, an ellipse, a rectangle, or a shape similar to these, so the first frame body 8 may be rolled into a sleeve shape, and may be a circle, an ellipse, a square, a rectangle, or a shape similar to these.

[0014] [Fireproof filler] 2, the refractory filler 5 is arranged so as to be in contact with at least one of the first frame body 8 and the inserter 21, and fills at least a part of the gap between the first frame body 8 and the inserter 21. At this time, at least one of the first frame body 8 and the inserter 21 functions as a support body that supports the refractory filler 5. By being arranged so as to be in contact with at least one of the first frame body 8 and the inserter 21 that function as a support body, the refractory filler 5 can remain in the gap between the first frame body 8 and the inserter 21 and can fill the gap between the first frame body 8 and the inserter 21. The fire-resistant filler 5 shown in Figure 2 is shown filling the entire interior of the first frame body 8, but it may be configured to fill only a partial area inside the first frame body 8 so as to block the gap between the first compartment A and the second compartment B. Examples of the fireproof filler 5 that can be used include amorphous materials such as putty, rock wool, glass wool, cellulose fiber, insulation board, gypsum board and board scraps, extruded polystyrene foam, phenolic foam, rigid urethane foam, and non-flammable urethane foam. To improve the handleability of the fireproof filler 5, which is an amorphous material, the fireproof filler 5 may be covered with an exterior material. The exterior material is not particularly limited as long as it is a material that can encapsulate the fireproof filler 5 and maintain the shape of the fireproof filler 5. Examples of the exterior material include metal and resin materials, and from the perspective of flexibility and handleability, a resin film such as a polyolefin resin is preferred. Alternatively, the exterior material may form a bag, and the fireproof filler 5 may be placed inside the bag.

[0015] The fire-resistant filler 5 is preferably a heat-absorbing material, a heat-insulating material, or a heat-expanding material, and more preferably a heat-expanding material that expands when heated. The heat-expanding material prevents the spread of fire by expanding during a fire. The heat-expanding material is preferably formed from a heat-expanding resin composition, as described below. To make the heat-expanding resin composition into an amorphous putty, the type and amount of resin, the amount of heat-expanding material such as heat-expanding graphite, and the type and amount of inorganic filler may be appropriately adjusted.

[0016] [Sheet-like member] The sheet-shaped member 3 is a member that closes at least a portion of the gap between the first frame 8 and the inserting body 21. 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 sheet-shaped member 3 allows the inserting body 21 to be inserted into the sheet-shaped member 3 through the slits 30 that extend to the outer edge. The sheet-shaped member 3 has segments 31 formed by incisions, one end of each segment 31 being a free end. Specifically, the sheet-shaped member 3 preferably has a plurality of segments 31 in which a plurality of slits 30 (four slits 30 in FIG. 1 ) formed by incisions intersect at a single point in the center of the sheet-shaped member 3, with the center of the sheet-shaped member 3 being the free end. With this configuration, when the inserter 21 is inserted through the center of the sheet-shaped member 3, each segment 31 is arranged along the outer periphery of the inserter 21.

[0017] As shown in FIG. 2 , the sheet-like member 3 is placed on the partition material 100 except for the cut pieces 31. The sheet-like member 3 is fastened to the partition material 100 by inserting fixing members such as screws or tackers into the partition material 100 from above the portions of the sheet-like member 3 placed on the partition material 100 except for the cut pieces 31. The sheet-like member 3 closes at least a portion of the gap between the first frame body 8 and the insert 21 with the cut pieces 31 placed along the outer periphery of the insert 21. However, the sheet-like member 3 may close at least a portion of the gap between the first frame body 8 and the insert 21 with the cut pieces 31 and portions other than the cut pieces 31. By placing the sheet-like member 3 so that the portions other than the cut pieces 31 and the cut pieces 31 are in contact with the outer peripheries of the partition material 100 and the insert 21, fire resistance can be improved.

[0018] The sheet-shaped member 3 may contain at least one of a fire-resistant material and a non-combustible material, and in this embodiment, it is preferable that the sheet-shaped member 3 has at least one layer containing a fire-resistant material (fire-resistant material layer). Note that the non-combustible material is defined in the Building Standards Act and the Enforcement Order of the Building Standards Act. The thickness of the sheet-like member 3 is not particularly limited, but is, for example, 0.1 to 20 mm, and preferably 0.5 to 10 mm.

[0019] More specifically, the sheet-like member 3 may have at least one layer selected from the group consisting of a substrate and a fire-resistant material layer, and may be a laminate having at least a substrate and a fire-resistant material layer, or a laminate having at least one of a substrate and a fire-resistant material layer and another layer. The fire-resistant material constituting the fire-resistant material layer is a thermally expandable member that expands when heated. The thermally expandable member prevents the spread of fire by expanding in the event of a fire. The thermally expandable member is preferably formed from a thermally expandable resin composition, as described below. The thickness of the fire-resistant material layer is not particularly limited, but is, for example, 0.1 to 15 mm, preferably 0.5 to 8 mm.

[0020] The substrate imparts rigidity to the sheet-like member 3, improving the ease of handling of the sheet-like member 3 and the ability to maintain its installation position. When the sheet-like member 3 has a substrate and a fire-resistant material layer, the substrate can suppress expansion of the fire-resistant material layer and control the shape of the expanded fire-resistant material layer. Examples of substrates include metal foils such as aluminum foil and copper foil, metal foil composites such as glass cloth and composites of metal foil and glass cloth such as aluminum-glass cloth, paper, cloth, and resin films. Among these, from the viewpoint of fire resistance, it is preferable that the substrate is made of a non-combustible material, and preferred specific examples include metal foil and metal foil composites. Note that when the sheet-like member 3 does not have a fire-resistant material layer, it is preferable that the substrate be made of a non-combustible material.

[0021] The thickness of the substrate is not particularly limited, but is, for example, 0.01 to 1 mm, and preferably 0.05 to 0.5 mm. When the thickness of the substrate is within the above range, the sheet-like member can be imparted with appropriate flexibility and rigidity.

[0022] The sheet-like member may have layers other than the above-mentioned substrate and fire-resistant material layer, and may also have an adhesive layer, a cushion layer, etc. as appropriate. The cushion layer imparts flexibility to the sheet-like member and improves its ability to conform to the irregularities of the member on which the sheet-like member is placed. The cushion layer is preferably a foam, and in particular, a flame-retardant foam. Examples of foams include urethane foam, phenol foam, styrene foam, PVC foam, polyethylene foam, cross-linked polyethylene foam, polypropylene foam, and other polyolefin foams, as well as synthetic rubber, with urethane foam being preferred. Flame-retardant foams are those foams blended with a flame retardant. The thickness of the cushion layer is, for example, 0.01 to 10 mm, preferably 0.05 to 5 mm. When the thickness of the cushion layer is within the above range, it is possible to impart appropriate conformability.

[0023] When the adhesive layer is arranged as the outermost layer, it functions to adhere the sheet-like member itself to other members (e.g., partition materials, etc.), and when arranged as an inner layer, it functions to adhere adjacent layers to each other, for example, it may adhere the substrate and fire-resistant material layer, or the substrate and cushion layer, or the cushion layer and fire-resistant material layer. The adhesive layer is preferably formed from an adhesive, and examples of the adhesive that can be used include acrylic adhesives, urethane adhesives, rubber adhesives, silicone resin adhesives, etc. The adhesive layer may be non-flammable, semi-non-flammable, or flame-retardant, and a flame retardant or the like may be blended into the adhesive used. The thickness of the adhesive layer is, for example, 5 to 400 μm, and preferably 10 to 150 μm. When the thickness of the adhesive layer is within the above range, it is possible to impart appropriate adhesiveness.

[0024] (Thermal Expandable Resin Composition) Next, the thermally expandable resin composition used in the fire-resistant material such as the fire-resistant material layer will be described in more detail. 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-shaped member 3 can be easily curved 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.

[0025] The expansion start temperature of the thermally expandable material is not particularly limited, but is preferably 150 to 350°C, more preferably 170 to 300°C, and even more preferably 180 to 280°C. By setting the temperature at or below these lower limits, the thermally expandable material is prevented from accidentally expanding due to heating other than that caused by a fire. Furthermore, by setting the temperature at or below the upper limits, the thermally expandable material is more likely to expand reliably due to heating caused by a fire. The expansion starting temperature of a thermally expandable material can be measured by heating a predetermined amount (e.g., 100 mg) of the material at a constant heating rate (e.g., 10°C / min) and measuring the temperature at which the normal force rises. Any measuring device can be used as long as it is capable of controlling the measurement temperature and measuring the normal stress, and a rheometer, for example, can be used. The expansion ratio of the thermally expandable member is preferably 3 times or more, and more preferably 10 times or more. The upper limit of the expansion ratio is not particularly limited, but is, for example, 70 times, and preferably 50 times. When multiple fireproof material layers with different expansion ratios are laminated on the sheet-like member, the expansion ratio may be selected within the above range. Furthermore, for example, the difference between the expansion ratio of the fireproof material layer farthest from the outer surface of the partition and the expansion ratio of the fireproof material layer closest to the outer surface of the partition is preferably 10 to 80 times, more preferably 20 to 70 times, and even more preferably 30 to 60 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 calculating the thickness by dividing the thickness of the test piece after heating by the thickness of the test piece before heating.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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 may 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 to 150 parts by mass, and preferably in the range of 10 parts by mass to 100 parts by mass, relative to 100 parts by mass of the resin component. When the plasticizer content is equal to or greater than these lower limits, good moldability is likely to be achieved, and when it is equal to or less than these upper limits, the molded article is provided with appropriate strength.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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, the thermal expandability is good. Furthermore, when the content is 300 parts by mass or less, the moldability is good, and the surface properties, mechanical properties, flexibility, etc. of the sealing member are also good. Furthermore, by selecting the content of thermally expandable graphite within the above range, the expansion ratio can be easily adjusted within a desired range. 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, more preferably in the range of 15 parts by mass or more and 100 parts by mass or less.

[0034] 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.

[0035] The thermally expandable resin composition may contain a known tackifier, which makes it easier to impart adhesiveness 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.

[0036] The thermally expandable member can be manufactured, for example, as follows: First, predetermined amounts of resin components, a thermally expandable material, and other additives, if necessary, are mixed in a mixer such as a kneading roll to obtain a thermally expandable resin composition. The thermally expandable resin composition may be diluted by adding a solvent as appropriate. The thermally expandable resin composition, diluted as necessary, is applied to a support such as a substrate or a release sheet, and then appropriately dried, cured, etc., to form a fire-resistant material layer (thermally expandable member) on one side of the support. Alternatively, the fire-resistant material layer may be formed on one side of the support by a known method such as extrusion molding. The fire-resistant material layer formed on the release sheet may be peeled from the release sheet to form a sheet-like member consisting of a single fire-resistant material layer. After peeling from the release sheet, the sheet-like member may be laminated on another layer to obtain a multilayered sheet-like member. Alternatively, the composition may be laminated on another layer while still laminated on the release sheet or another support.

[0037] [Construction method] The construction method for the fireproof structure in this embodiment includes the steps of: placing a cylindrical first frame 8, through which an insert 21 is passed, in a partition material 100 having an opening 101 formed therein; the first frame 8 is in contact with the inner circumferential surface of the opening 101 of the partition material 100; and the first frame 8 is arranged at least from one end of the partition material 100 to the other end of the partition material 100. Then, a fireproof filler 5 is placed in contact with at least one of the first frame 8 and the insert 21, thereby sealing at least a portion of the gap between the first frame 8 and the insert 21. Finally, a fireproofing material is placed to seal at least a portion of the gap between the first frame 8 and the insert 21. In this embodiment, a sheet-like member 3 is prepared as the fireproofing material; a piece 31 of the sheet-like member 3 is placed along the outer periphery of the insert 21; and the remaining portion of the sheet-like member 3 other than the piece 31 is placed on the partition material 100.

[0038] According to the fire-resistant structure of this embodiment, by providing a first frame 8 that is in contact with the inner periphery of an opening 101 formed in a partition material 100 in a partition section of a building and that is disposed inside the opening 101 so as to span at least from one end of the partition material 100 to the other, it is possible to improve the ease of application of a fire-resistant material that imparts fire resistance. In addition, a portion of the first frame 8 can be confirmed from the outside, and the fire-resistant material can be reliably installed on the confirmed first frame 8 to perform fire resistance treatment. Therefore, according to the fire-resistant structure of this embodiment, it is possible to reduce variation in fire resistance in the partition material 100 provided with the opening 101 and maintain sufficient fire resistance.

[0039] [Modification 1 of the First Embodiment] In the first embodiment, the partition material 100 is a wall surface of a building, and the configuration of the fire-resistant structure on the wall surface is shown. However, as shown in Fig. 3, the fire-resistant structure is a member that separates compartments (a first compartment A and a second compartment B) on the ceiling, floor, etc. of a building, and the fire-resistant structure can be configured on the ceiling or floor.

[0040] [Modification 2 of the First Embodiment] In the first embodiment, the first frame 8 has a length equal to the thickness of the partition material 100. However, as shown in FIG. 4, the first frame 8 may have a length that exceeds the thickness of the partition material 100 and may extend beyond one outer surface of the partition material 100.

[0041] As shown in Fig. 4, the refractory filler 5 is arranged so as to be in contact with at least one of the first frame body 8 and the inserter 21, and fills at least a part of the gap between the first frame body 8 and the inserter 21. At this time, at least one of the first frame body 8 and the inserter 21 functions as a support body that supports the refractory filler 5. By being arranged so as to be in contact with at least one of the first frame body 8 and the inserter 21 that function as a support body, the refractory filler 5 can remain in the gap between the first frame body 8 and the inserter 21 and can fill the gap between the first frame body 8 and the inserter 21. The fire-resistant filling material 5 shown in Figure 4 is shown filling the side of the partition material 100 inside the first frame body 8 that protrudes outward from one outer surface, but it may also be configured to fill the entire interior of the first frame body 8, or it may be configured to fill a partial area inside the first frame body 8 so as to block the first compartment A and the second compartment B.

[0042] As shown in FIG. 4 , the sheet-like member 3 is disposed on the outer peripheral surface of the first frame 8 on the side where the portion other than the segment 31 protrudes outward from one outer surface of the partition material 100. The sheet-like member 3 is fastened to the partition material 100 by adhering the portion other than the segment 31 disposed on the outer peripheral surface of the first frame 8 to the outer peripheral surface of the first frame 8 using known fastening means such as adhesives, pressure-sensitive adhesives, adhesive tape, or fastening members such as tackers and screws. The adhesives, pressure-sensitive adhesives, and adhesive tapes are preferably non-combustible, semi-non-combustible, or flame-retardant materials, and the adhesives, pressure-sensitive adhesives, etc. may be blended with a flame retardant. The sheet-like member 3 blocks at least a portion of the gap between the first frame 8 and the insert 21 with the segment 31 disposed along the outer periphery of the insert 21. However, the sheet-like member 3 may also block at least a portion of the gap between the first frame 8 and the insert 21 with the segment 31 and portions other than the segment 31. By arranging the sheet-like member 3 so that the portions other than the segment 31 and the segment 31 are in contact with the outer peripheral surface of the first frame 8 and the outer periphery of the insert 21, the fire resistance can be improved.

[0043] [Modification 2-1 of the first embodiment] In the second modification of the first embodiment, the first frame 8 has a length that exceeds the thickness of the partition material 100 and extends outward from the outer surface of one side of the partition material 100. However, as shown in Fig. 5, the first frame 8 can also have a length that exceeds the thickness of the partition material 100 and extends outward from the outer surfaces of both sides of the partition material 100. In this modification, both sides of the partition material 100 can be configured with a fire-resistant structure.

At this time, at least one of the first frame body 8 and the inserter 21 functions as a support body that supports the refractory filler 5. By being arranged so as to be in contact with at least one of the first frame body 8 and the inserter 21 that function as a support body, the refractory filler 5 can remain in the gap between the first frame body 8 and the inserter 21 and can fill the gap between the first frame body 8 and the inserter 21. The fire-resistant filling material 5 shown in Figure 6 is shown filling the side of the partition material 100 inside the first frame body 8 that protrudes outward from one outer surface, but it may also be configured to fill the entire interior of the first frame body 8, or it may be configured to fill a partial area inside the first frame body 8 so as to block the first compartment A and the second compartment B.

[0047] As shown in FIG. 6 , the sheet-like member 3 is arranged on the inner circumferential surface of the first frame 8 on the side where the portion other than the segment 31 protrudes outward from one outer surface of the partition material 100. The sheet-like member 3 is fastened to the partition material 100 by adhering the portion other than the segment 31 arranged on the inner circumferential surface of the first frame 8 to the inner circumferential surface of the first frame 8 using known fastening means such as adhesives, pressure-sensitive adhesives, adhesive tape, or fastening members such as tackers and screws. Here, the adhesives, pressure-sensitive adhesives, and adhesive tapes are preferably made of non-combustible, semi-non-combustible, or flame-retardant materials, and it is preferable to blend a flame retardant or the like into the adhesives, pressure-sensitive adhesives, etc. The sheet-like member 3 at least partially fills the gap between the first frame 8 and the insert 21 with the segment 31 arranged along the outer periphery of the insert 21. However, the sheet-like member 3 may close at least a part of the gap between the first frame body 8 and the insert 21 with the segments 31 and portions other than the segments 31. By placing the portions of the sheet-like member 3 other than the segments 31 and the segments 31 in contact with the inner peripheral surface of the first frame body 8 and the outer periphery of the insert 21, the fire resistance performance can be improved.

However, as shown in Fig. 7, the first frame 8 may have a length that exceeds the thickness of the partition material 100 and may extend beyond one outer surface of the partition material 100.

[0051] As shown in FIG. 7 , the sheet-like member 3 is arranged on the inner circumferential surface of the first frame 8 on the side where the portion other than the segment 31 protrudes outward from one outer surface of the partition material 100. The sheet-like member 3 is fastened to the partition material 100 by adhering the portion other than the segment 31 arranged on the inner circumferential surface of the first frame 8 to the inner circumferential surface of the first frame 8 using known fastening means such as adhesives, pressure-sensitive adhesives, adhesive tape, or fastening members such as tackers and screws. Here, the adhesives, pressure-sensitive adhesives, and adhesive tapes are preferably made of non-combustible, semi-non-combustible, or flame-retardant materials, and it is preferable to blend a flame retardant or the like into the adhesives, pressure-sensitive adhesives, etc. The sheet-like member 3 at least partially fills the gap between the first frame 8 and the insert 21 with the segment 31 arranged along the outer periphery of the insert 21. However, the sheet-like member 3 may close at least a part of the gap between the first frame body 8 and the insert 21 with the segments 31 and portions other than the segments 31. By placing the portions of the sheet-like member 3 other than the segments 31 and the segments 31 in contact with the inner peripheral surface of the first frame body 8 and the outer periphery of the insert 21, the fire resistance performance can be improved.

By being arranged so as to be in contact with at least one of the first frame body 8, the sheet-like member 3, and the inserts 21 that function as a support, the refractory filler 5 can remain in the gap between the first frame body 8, the sheet-like member 3, and the inserts 21, and can fill the gap between the first frame body 8, the sheet-like member 3, and the inserts 21.

[0053] [Modification 4-1 of the first embodiment] In the fourth modification of the first embodiment, the first frame 8 has a length that exceeds the thickness of the partition material 100 and is configured to extend outward from the outer surface of one side of the partition material 100.

However, the compartment penetration treatment material may also be configured to further include a second frame body 9, as shown in Fig. 8. In this modified example, the outer diameter d2 of the second frame body 9 is larger than the outer diameter d1 of the first frame body 8.

[0056] [Second frame] 8 and 9, the second frame 9 is cylindrical, through which the insert 21 passes, and is provided on the outer surface side of the partition material 100 without contacting the inner peripheral surface of the opening 101. By providing the second frame 9 as a compartment penetration treatment material, a more reliable closed structure can be achieved, and fire resistance can be improved. The second frame 9 may be made of metal, resin, paper, or the like. The second frame 9 may be sleeve-shaped and provided on the outer surface of the partition material 100. For example, the second frame 9 may be a metal sleeve such as a steel sleeve formed from steel, resin, or paper, or a resin sleeve or a paper sleeve. Alternatively, the second frame 9 may be a sleeve-shaped sleeve formed by rolling a metal sheet, a resin sheet, or a paper sheet and fixing it appropriately. The second frame 9 may also be formed by assembling two or more members into a single frame. The outer diameter d2 of the second frame 9 shown in FIGS. 8 and 9 is larger than the outer diameter d1 of the first frame 8. The second frame 9 may also be formed in a sleeve shape by facing the ends of sheet-like fire-resistant material or by overlapping the ends of sheet-like fire-resistant material to form a joint 90. The second frame 9 formed from a sleeve-shaped fire-resistant material or various sheets allows the internal space through which the insert 21 is inserted to be adjustable. When the sheet-like fire-resistant material or various sheets are formed into a sleeve shape, the joint 90 between the ends may be bonded with an adhesive, pressure-sensitive adhesive, adhesive tape, or the like. The adhesive, pressure-sensitive adhesive, and adhesive tape are preferably made of a non-combustible material, a quasi-non-combustible material, or a flame-retardant material, and the adhesive, pressure-sensitive adhesive, or the like may contain a flame retardant.

[0057] As shown in FIG. 9 , the sheet-like member 3 is placed on the partition material 100 except for the sections 31. The sheet-like member 3 is fastened to the partition material 100 by inserting fixing members such as screws or tackers into the partition material 100 from above the sections of the sheet-like member 3 placed on the partition material 100 except for the sections 31. The sheet-like member 3 closes at least a portion of the gap between the first frame body 8 and the insert 21 with the sections 31 placed along the outer periphery of the insert 21. However, the sheet-like member 3 may close at least a portion of the gap between the first frame body 8 and the insert 21 with the sections 31 and portions other than the sections 31. By placing the sections 31 and the sections 31 of the sheet-like member 3 so that they are in contact with the outer peripheries of the partition material 100 and the insert 21, fire resistance can be improved.

[0058] As shown in Fig. 9, the refractory filler 5 is arranged so as to be in contact with at least one of the second frame 9, the sheet-like member 3, and the insert 21, and fills at least a part of the gap between the second frame 9, the sheet-like member 3, and the insert 21. At this time, at least one of the second frame 9, the sheet-like member 3, and the insert 21 functions as a support for supporting the refractory filler 5. By being arranged so as to be in contact with at least one of the second frame 9, the sheet-like member 3, and the insert 21 that function as a support, the refractory filler 5 can remain in the gap between the second frame 9, the sheet-like member 3, and the insert 21, and can fill the gap between the second frame 9, the sheet-like member 3, and the insert 21.

[0059] [Modification 5-1 of the first embodiment] In the fifth modification of the first embodiment, the partition material 100 is a wall surface of a building, and the configuration of the fire-resistant structure on the wall surface has been shown. However, the fire-resistant structure may be a member that separates compartments (a first compartment A and a second compartment B) on the ceiling, floor, etc. of a building, as shown in Fig. 10, and the fire-resistant structure on the ceiling or floor may be configured. The fire-resistant structure shown in Fig. 10 can prevent water from entering the opening 101 by sealing the opening 101 with a compartment-penetrating material, and can also effectively prevent water leaks.

[0060] [Modification 6 of the First Embodiment] In the first embodiment, the compartment penetration material in the fireproof structure is configured to include a first frame body 8, a sheet-like member 3, and a fireproof filler material 5. However, the compartment penetration material may also be configured to further include a second frame body 9A, as shown in Fig. 11. In this modification, the outer diameter d3 of the second frame body 9A is smaller than the outer diameter d1 of the first frame body 8.

[0061] [Second frame] As shown in FIGS. 11 and 12, the second frame 9A is cylindrical and has the insert 21 inserted therethrough. The second frame 9A is provided on the outer surface of the partition member 100 without contacting the inner circumferential surface of the opening 101. The second frame 9A may be made of metal, resin, paper, or the like. The second frame 9A may be sleeve-shaped and provided on the outer surface of the partition material 100. It may be formed of steel or a sheet-like fire-resistant material with its ends facing each other or with its ends overlapping to form a joint 90. The second frame 9A, formed of a sleeve-shaped fire-resistant sheet, allows the internal space through which the insert 21 is inserted to be adjusted. The outer diameter d3 of the second frame 9A shown in FIGS. 11 and 12 is smaller than the outer diameter d1 of the first frame 8. When the sheet-like fire-resistant material is formed into a sleeve, the joint 90 between the ends may be bonded with an adhesive, pressure-sensitive adhesive, adhesive tape, or the like. The adhesive, pressure-sensitive adhesive, or adhesive tape is preferably made of a non-combustible, semi-non-combustible, or flame-retardant material, and a flame retardant may be blended into the adhesive, pressure-sensitive adhesive, or the like. The adhesive tape comprises a substrate and an adhesive layer provided on one side of the substrate, and it is preferable that the substrate and the adhesive layer are each made of a non-combustible material, a semi-non-combustible material, or a flame-retardant material. The thickness of the second frame 9A is not particularly limited, but is, for example, 0.2 to 10 mm, and preferably 0.5 to 6 mm.

[0062] As shown in FIG. 12 , the sheet-like member 3 is placed on the partition material 100 except for the sections 31. The sheet-like member 3 is fastened to the partition material 100 by inserting fixing members such as screws or tackers into the partition material 100 from above the sections of the sheet-like member 3 placed on the partition material 100 except for the sections 31. The sheet-like member 3 closes at least a portion of the gap between the first frame body 8 and the insert 21 with the sections 31 arranged along the outer periphery of the insert 21. However, the sheet-like member 3 may close at least a portion of the gap between the first frame body 8 and the insert 21 with the sections 31 and portions other than the sections 31. By placing the sections of the sheet-like member 3 other than the sections 31 and the sections 31 in contact with the outer peripheries of the partition material 100 and the insert 21, fire resistance can be improved. Furthermore, by positioning the entire area of ​​the sheet-like member 3 other than the pieces 31 arranged on the partition material 100 outside the outer periphery of the second frame body 9A, a more secure closed structure can be achieved, thereby improving fire resistance.

[0063] 12 , the refractory filler 5 is arranged so as to be in contact with at least one of the second frame body 9A, the sheet-like member 3, and the inserts 21, and fills at least a portion of the gaps between the second frame body 9A, the sheet-like member 3, and the inserts 21. At this time, at least one of the second frame body 9A, the sheet-like member 3, and the inserts 21 function as supports that support the refractory filler 5. By being arranged so as to be in contact with at least one of the second frame body 9A, the sheet-like member 3, and the inserts 21 that function as supports, the refractory filler 5 can remain in the gaps between the second frame body 9A, the sheet-like member 3, and the inserts 21, and can fill the gaps between the second frame body 9A, the sheet-like member 3, and the inserts 21.

[0064] [Modification 6-1 of the first embodiment] In the second modification of the first embodiment, the partition material 100 is a wall surface of a building, and the configuration of the fire-resistant structure on the wall surface is shown. However, the fire-resistant structure may be a member that separates compartments (first compartment A and second compartment B) on the ceiling, floor, etc. of a building, as in the first modification 5-1 shown in Fig. 10, and the fire-resistant structure may be a configuration of the ceiling or floor.

[0065] [Seventh Modification of the First Embodiment] In the sixth modification of the first embodiment, the compartment penetration treatment material in the fireproof structure is configured to include the first frame body 8, the second frame body 9A, the sheet-like member 3, and the fireproof filler material 5. However, the compartment penetration treatment material may be configured to further include a cover member 6, as shown in FIG.

[0066] [Cover member] The cover member 6 is a member that closes at least a part of the gap between the first frame body 8 and the inserting body 21. For example, as shown in FIG. 13 , the cover member 6 is a single sheet having slits 60 for inserting the inserting body 21 therein, and at least one of the slits 60 may extend to the outer edge of the cover member 6. The slits 60 are formed by cutting. The inserting body 21 can be inserted into the cover member 6 through the slits 60 that extend to the outer edge.

[0067] As shown in Fig. 14, the cover member 6 is installed so that its edge is connected to the outer peripheral surface of the second frame body 9A. The cover member 6 is fastened to the partition material 100 by adhering it to the outer peripheral surface of the second frame body 9A using known fastening means such as adhesives, pressure-sensitive adhesives, adhesive tape, and fastening members such as tackers and screws. Here, the adhesives, pressure-sensitive adhesives, and adhesive tapes are preferably made of non-combustible materials, semi-non-combustible materials, or flame-retardant materials, and it is advisable to blend flame retardants into the adhesives, pressure-sensitive adhesives, etc. The portion of the cover member 6 that covers the second frame body 9A near the center surrounds the penetrating body 21 so as to be in contact with it, and is fixed to the penetrating body 21 by a string-like member 22 that is wound around it from the outside. The string-like member 22 may be any bendable member, and is preferably a wire member that includes a wire. The wire member may be a metal wire alone, or a resin-coated wire such as Nejirikko (registered trademark) in which a metal wire is coated with resin, or a wire and fiber entangled member such as a maul. When a wire member is used, the cover member 6 can be fixed to the penetrating body 21 simply by twisting or twisting it. In another embodiment (not shown), the cover member 6 has a portion covering the second frame body 9A that surrounds the inserter 21 so as to be in contact with the inserter 21, and is fixed to the inserter 21 by adhesive tape wound from the outside (i.e., the side opposite the inserter 21). The adhesive tape preferably has a substrate and an adhesive layer provided on one surface of the substrate. The substrate may be made of paper, resin film, cloth, or the like, or may be made of the non-flammable materials described above. The adhesive layer may be made of, for example, an acrylic adhesive, a urethane adhesive, a rubber adhesive, or a silicone resin adhesive. The adhesive may also contain a known flame retardant. In another embodiment not shown, the cover member 6 may have a portion covering the second frame body 9A that surrounds the penetrating body 21 so as to be in contact with it, and may be fixed to the penetrating body 21 by a fixing member such as a stapler or screw installed from the outside (i.e., the side opposite the penetrating body 21). In another embodiment not shown, the cover member 6 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 constitute the outermost layer of the cover member 6. That is, the cover member 6 may have at least one of an adhesive fire-resistant material layer and an adhesive layer on the inner side (i.e., the side facing the inserter 21). In another embodiment (not shown), the cover member 6 may be fixed by, for example, a fixing piece formed by a notch formed in the cover member 6. The fixing piece may, for example, maintain the reduced-diameter shape of the cover member 6 surrounding the inserter 21, thereby fixing the cover member 6 to the inserter 21. Specifically, the tip of the cover member 6 may have a stacked structure in which multiple cover members 6 are stacked, and multiple notches may be formed at intervals in the circumferential direction in the tip, with tongue-shaped fixing pieces provided between adjacent notches in the circumferential direction, and the fixing pieces themselves may have a stacked structure. The cover member 6 is fixed to the inserter 21 by maintaining the reduced-diameter shape with the fixing piece having the stacked structure. The stacked structure may be formed, for example, by folding back the tip of the cover member 6, and the notch may, for example, be provided obliquely relative to the axial direction.

[0068] The cover member 6 is preferably installed so as to be in contact with the second frame body 9A and the insert 21. By installing the cover member 6 so as to be in contact with the second frame body 9A and the insert 21, the opening 101 of the partition material 100 can be blocked by the second frame body 9A and the cover member 6, thereby improving fire resistance.

[0069] The cover member 6 is installed so as to form a gap between itself and the second frame body 9A. The gap between the second frame body 9A and the cover member 6 allows the cover member 6 to be fixed with a margin for axial movement of the insert 21. Since the cover member 6 is fixed to the insert 21 with a margin, even if the insert 21, located inside the second frame body 9A and the cover member 6, is moved axially after the second frame body 9A and the cover member 6 are installed, the margin of the cover member 6 prevents the second frame body 9A and the cover member 6 from moving together with the insert 21. By preventing the second frame body 9A and the cover member 6 from moving together with the insert 21, it is possible to prevent the sheet-like member 1B and the cover member 6 from shifting out of the fire-resistant structure. In other words, this configuration allows the second frame body 9A and the cover member 6 to be maintained in an appropriate position in the fire-resistant structure, thereby maintaining the fire resistance of the fire-resistant structure. There is a gap between the second frame body 9A and the cover member 6, and various configurations can be used to fix the cover member 6 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 6 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 6 is fixed to the inserting body 21 with some slack, can be mentioned.

[0070] The cover member 6 may be made 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 made of a non-combustible material layer. Furthermore, the cover member 6 may have layers other than the fire-resistant and non-combustible material layers, such as a material layer made of a material other than a non-combustible material, an adhesive layer, etc. The cover member 6 is preferably made of a metal foil such as aluminum foil, glass cloth, or a metal foil composite, which is a composite of metal foil and glass cloth such as aluminum glass cloth. These constitute the non-combustible material layer. Among these, aluminum glass cloth is more 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, 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 6. Therefore, even if the cover member 6 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.

[0071] As described above, the cover member 6 is preferably a sheet that can be deformed to cover the second frame body 9A, and is preferably thinner than the sheet-like member 1B so that it is flexible and can be easily deformed. The thickness of the cover member 6 is not particularly limited, but is, for example, 0.01 to 1 mm, and preferably 0.05 to 0.5 mm.

[0072] The fire-resistant material layer used in the cover member 6 is preferably a thermally expandable material that expands when heated. The thermally expandable material prevents the spread of fire by expanding in the event of a fire. The thermally expandable material is preferably formed from the above-mentioned thermally expandable resin composition. The fire-resistant material layer may also have adhesive properties. The thickness of the fire-resistant material layer is not particularly limited, but is, for example, 0.01 to 1 mm, preferably 0.05 to 0.5 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 6. Therefore, even if the cover member 6 has a fire-resistant material layer, it can be wrapped around the outer periphery of the insert 21. Furthermore, when the thickness is equal to or greater than the lower limit, fire resistance is more easily ensured.

[0073] The cover member 6 may have an adhesive fire-resistant material layer or an adhesive layer. The adhesive fire-resistant material layer and the adhesive layer may constitute the outermost layer of the cover member 6. With the above-described configuration, the cover member 6 can be fixed to the sheet-like member 1B or the insert 21 without using a fixing member separate from the cover member 6. Furthermore, by making the fire-resistant material layer itself adhesive, it is not necessary to provide an adhesive layer, and therefore the configuration of the cover member 6 can be further simplified. When the cover member 6 has an adhesive fireproof material layer or an adhesive layer on its outermost layer, a release sheet may be attached to the outermost layer. The release sheet may be peeled off from the outermost layer when in use.

[0074] [Modification 7-1 of the first embodiment] In the seventh modification of the first embodiment, the partition material 100 is a wall surface of a building, and the configuration of the fire-resistant structure on the wall surface is shown. However, the fire-resistant structure is a member that separates compartments (a first compartment A and a second compartment B) on the ceiling, floor, etc. of a building, as shown in Fig. 15, and the fire-resistant structure can be configured as a ceiling or floor.

[0075] [Second embodiment] Next, a second embodiment of the present invention will be described in detail. As shown in Figs. 16 and 17, the compartment penetration treatment material in the fireproof structure according to the second embodiment is composed of a first frame body 8, a tape-shaped member 4, a fireproof filler material 5, etc. Below, differences between the second embodiment and the first embodiment will be described. Also, parts whose description is omitted are the same as those in the first embodiment. Also, in the following description, parts having the same configuration as those in the first embodiment will be given the same reference numerals.

[0076] [Tape-shaped member] The tape-shaped member 4 is a member that closes at least a part of the gap between the first frame body 8 and the inserting body 21. As shown in Fig. 17, the tape-shaped member 4 is arranged so as to cover a part of the outer periphery of the inserting body 21. The tape-shaped member 4 is a member that covers the inserting body 21 so as to surround it, and is installed so that at least a part of it is in contact with the outer periphery of the inserting body 21. From the viewpoint of improving the ability to maintain the installed position, it is preferable to install it by wrapping it around the outer periphery of the inserting body 21 one or more times. The tape-shaped member 4 may contain at least one of a fire-resistant material and a non-combustible material, and in this embodiment, it preferably has at least one layer containing a fire-resistant material (fire-resistant layer). More specifically, the sheet-shaped member 3 may have at least one layer selected from the group consisting of a substrate and a fire-resistant material layer, and may be a laminate having at least a substrate and a fire-resistant material layer, or a laminate having at least one of a substrate and a fire-resistant material layer and another layer. Examples of other layers include an adhesive layer and a cushion layer. Furthermore, if the tape-shaped member 4 does not have a fire-resistant material layer, it may have a substrate made of a non-combustible material. The details of the substrate, adhesive layer, cushion layer, and fire-resistant material layer are as described above. 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.

[0077] 17 , the refractory filler 5 is arranged so as to be in contact with at least one of the first frame body 8, the tape-shaped member 4, and the inserts 21, and fills at least a part of the gap between the first frame body 8, the tape-shaped member 4, and the inserts 21. At this time, at least one of the first frame body 8, the tape-shaped member 4, and the inserts 21 function as a support for supporting the refractory filler 5. By being arranged so as to be in contact with at least one of the first frame body 8, the tape-shaped member 4, and the inserts 21 that function as a support, the refractory filler 5 can remain in the gap between the first frame body 8, the tape-shaped member 4, and the inserts 21, and can fill the gap between the first frame body 8, the tape-shaped member 4, and the inserts 21. The fire-resistant filling material 5 shown in Figure 17 is shown filling the side of the partition material 100 inside the first frame body 8 that protrudes outward from one outer surface, but it may also be configured to fill the entire interior of the first frame body 8, or it may be configured to fill a partial area inside the first frame body 8 so as to block the gap between the first compartment A and the second compartment B.

[0080] [Modification 2 of the second embodiment] In the second embodiment, the compartment penetration material in the fireproof structure is configured to include a first frame body 8, a tape-shaped member 4, and a fireproof filler material 5. However, the compartment penetration material may also be configured to further include a second frame body 9, as shown in Fig. 20. In this modification, the outer diameter d2 of the second frame body 9 is larger than the outer diameter d1 of the first frame body 8.

[0081] As shown in Fig. 21 , the refractory filler 5 in this modification is arranged so as to be in contact with at least one of the second frame 9, the sheet-shaped member 3, and the inserts 21, and fills at least a portion of the gaps between the second frame 9, the tape-shaped member 4, and the inserts 21. At this time, at least one of the second frame 9, the tape-shaped member 4, and the inserts 21 function as a support for supporting the refractory filler 5. By being arranged so as to be in contact with at least one of the second frame 9, the tape-shaped member 4, and the inserts 21 that function as supports, the refractory filler 5 can remain in the gaps between the second frame 9, the sheet-shaped member 3, and the inserts 21, and can fill the gaps between the second frame 9, the tape-shaped member 4, and the inserts 21.

However, as shown in FIG. 24, the compartment penetration material may also be configured to further include a second frame 9A, and to include fillers 5A and 5B instead of the fireproof filler 5. In this modified example, the outer diameter d3 of the second frame 9A is smaller than the outer diameter d1 of the first frame 8.

[0090] As shown in Fig. 27, the cover member 6 is installed so that its edge is connected to the outer peripheral surface of the second frame body 9A. The cover member 6 is fastened to the partition material 100 by adhering it to the outer peripheral surface of the second frame body 9A using known fastening means such as adhesives, pressure-sensitive adhesives, adhesive tape, and fastening members such as tackers and screws. Here, the adhesives, pressure-sensitive adhesives, and adhesive tapes are preferably made of non-combustible materials, semi-non-combustible materials, or flame-retardant materials, and it is advisable to blend flame retardants into the adhesives, pressure-sensitive adhesives, etc. The portion of the cover member 6 that covers the second frame body 9A near the center surrounds the penetrating body 21 so as to be in contact with it, and is fixed to the penetrating body 21 by a string-like member 22 that is wound around it from the outside. The string-like member 22 may be any bendable member, and is preferably a wire member that includes a wire. The wire member may be a metal wire alone, or a resin-coated wire such as Nejirikko (registered trademark) in which a metal wire is coated with resin, or a wire and fiber entangled member such as a maul.

[0091] The cover member 6 is preferably installed so as to be in contact with the second frame body 9A and the insert 21. By installing the cover member 6 so as to be in contact with the second frame body 9A and the insert 21, the opening 101 of the partition material 100 can be blocked by the second frame body 9A and the cover member 6, thereby improving fire resistance.

[0092] [Modification 5-1 of the second embodiment] In the fifth modification of the second embodiment, the partition material 100 is a wall surface of a building, and the configuration of the fire-resistant structure on the wall surface is shown.

[0093] [Modification 6 of the Second Embodiment] In the second embodiment, the compartment penetration material in the fireproof structure is configured to include a first frame body 8, a tape-shaped member 4, and a fireproof filler material 5. However, as shown in Fig. 28, the compartment penetration material may also be configured to further include a second frame body 9 and a cover member 6. In this modification, the outer diameter d2 of the second frame body 9 is larger than the outer diameter d1 of the first frame body 8.

[0094] As shown in Fig. 29, the cover member 6 is installed so that its edge is connected to the outer peripheral surface of the second frame body 9. The cover member 6 is fastened to the partition material 100 by adhering it to the outer peripheral surface of the second frame body 9 using known fastening means such as adhesives, pressure-sensitive adhesives, adhesive tape, and fastening members such as tackers and screws. Here, the adhesives, pressure-sensitive adhesives, and adhesive tapes are preferably made of non-combustible materials, semi-non-combustible materials, or flame-retardant materials, and it is advisable to blend flame retardants into the adhesives, pressure-sensitive adhesives, etc. The portion of the cover member 6 that covers the second frame 9 near the center surrounds the penetrating body 21 so as to be in contact with it, and is fixed to the penetrating body 21 by a string-like member 22 that is wound around it from the outside. The string-like member 22 may be any bendable member, and is preferably a wire member that includes a wire. The wire member may be a metal wire alone, or a resin-coated wire such as Nejirikko (registered trademark) in which a metal wire is coated with resin, or a wire and fiber entangled member such as a maul. When a wire member is used, the cover member 6 can be fixed to the penetrating body 21 simply by twisting or twisting it.

[0095] The cover member 6 is preferably installed so as to be in contact with the second frame body 9 and the insert 21. By installing the cover member 6 so as to be in contact with the second frame body 9 and the insert 21, the opening 101 of the partition material 100 can be blocked by the second frame body 9 and the cover member 6, thereby improving fire resistance.

[0096] [Modification 6-1 of the second embodiment] In the sixth modification of the second embodiment, the partition material 100 is a wall surface of a building, and the configuration of the fire-resistant structure on the wall surface is shown. However, the fire-resistant structure may be a ceiling, floor, etc. of a building, which is a member that separates compartments (first compartment A and second compartment B), as in the first modification 1-2 shown in Fig. 19, and the fire-resistant structure may be configured as a ceiling or floor.

[0097] [Third embodiment] Next, a third embodiment of the present invention will be described in detail. As shown in Figures 30 and 31, the compartment penetration treatment material in the fire-resistant structure according to the third embodiment is composed of a first frame body 8, a sleeve-shaped member 8A, a cover member 6, etc. Below, 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 and second embodiments. Furthermore, in the following description, members having the same configuration as those in the first and second embodiments will be given the same reference numerals. As shown in FIG. 31, the first frame 8 of this embodiment has a length that exceeds the thickness of the partition material 100, and is present protruding outward from one outer surface of the partition material 100.

[0098] [Sleeve-shaped member] As shown in FIG. 31 , the sleeve-shaped member 8A is installed so as to be in contact with the inner peripheral surface of the first frame 8, for example. In other words, the sleeve-shaped member 8A is installed so as to be present inside the first frame 8. The sleeve-shaped member 8A is preferably made of a fire-resistant material. The fire-resistant material is as described above. By placing the sleeve-shaped member 8A inside the first frame 8 in a state where the first frame 8 and the sleeve-shaped member 8A are in contact with each other, in the event of a fire, the sleeve-shaped member 8A can expand inside the first frame 8 and close the gap between it and the insert 21.

[0099] The sleeve-shaped member 8A may be formed by facing the ends of a sheet-like fire-resistant material to each other, or by overlapping the ends of the sheet-like fire-resistant material to form a joint 81. The sleeve-shaped member 8 formed by sleeve-shaping a sheet-like fire-resistant material can adjust the size of the internal space through which the insert 21 is inserted. The sleeve-shaped member 8A may be placed on the inner surface of the first frame body 8 after being formed into a sleeve shape, or the sheet-shaped fire-resistant material that will become the sleeve-shaped member 8A may be placed on the sheet-shaped fire-resistant material that will become the first frame body 8 before being formed into a sleeve shape, and the first frame body 8 and the sleeve-shaped member 8A may be integrally formed into a sleeve shape to place the sleeve-shaped member 8A on the inner surface of the first frame body 8.

[0100] As shown in Fig. 31, the cover member 6 is installed so that its edge is connected to the outer peripheral surface of the first frame 8 on the side that protrudes outward from the outer surface of one side of the partition material 100. The cover member 6 is fastened to the partition material 100 by adhering it to the outer peripheral surface of the first frame 8 using known fastening means such as adhesives, pressure-sensitive adhesives, adhesive tape, and fastening members such as tackers and screws. Here, the adhesives, pressure-sensitive adhesives, and adhesive tapes are preferably made of non-combustible materials, semi-non-combustible materials, or flame-retardant materials, and it is advisable to blend flame retardants or the like into the adhesives, pressure-sensitive adhesives, etc. The portion of the cover member 6 that covers the first frame 8 near the center surrounds the penetrating body 21 so as to be in contact with it, and is fixed to the penetrating body 21 by a string-like member 22 that is wound around it from the outside. The string-like member 22 may be any bendable member, and is preferably a wire member that includes a wire. The wire member may be a metal wire alone, or a resin-coated wire such as Nejirikko (registered trademark) in which a metal wire is coated with resin, or a wire and fiber entangled member such as a maul. When a wire member is used, the cover member 6 can be fixed to the penetrating body 21 simply by twisting or twisting it.

[0101] The cover member 6 is preferably installed so as to be in contact with the first frame body 8 and the insert 21. By installing the cover member 6 so as to be in contact with the first frame body 8 and the insert 21, the opening 101 of the partition material 100 can be blocked by the first frame body 8 and the cover member 6, thereby improving fire resistance.

[0102] [Modification 1-1 of the third embodiment] In the third embodiment, the first frame 8 has a length that exceeds the thickness of the partition material 100 and is configured to extend beyond the outer surface of one side of the partition material 100. However, as shown in Fig. 32, the first frame 8 can be configured to have a length that exceeds the thickness of the partition material 100 and to extend beyond the outer surfaces of both sides of the partition material 100. In this modified example, both sides of the partition material 100 can be configured to have a fire-resistant structure.

[0103] [Modification 1-2 of the third embodiment] In the third embodiment, the partition material 100 is a wall surface of a building, and the configuration of the fire-resistant structure on the wall surface has been shown. However, the fire-resistant structure is a member that separates compartments (a first compartment A and a second compartment B) on the ceiling, floor, etc. of a building, as shown in Fig. 33, and the fire-resistant structure can be configured as a ceiling or floor.

[0104] [Modification 2 of the third embodiment] In the third embodiment, the sleeve-shaped member 8A is configured to be installed so as to be present inside the first frame body 8. However, as shown in Fig. 34, the sleeve-shaped member 8A may be configured so that at least a portion thereof is present inside the first frame body 8 and a portion thereof protrudes outside the first frame body 8.

[0105] As shown in FIG. 34 , the sleeve-shaped member 8A is installed so that one end thereof contacts the inner circumferential surface of the first frame 8. In other words, a portion of the sleeve-shaped member 8A is installed so that it is inside the first frame 8. By installing the sleeve-shaped member 8 inside the first frame 8 with a portion of the sleeve-shaped member 8A and the first frame 8 in contact with each other, in the event of a fire, a portion of the sleeve-shaped member 8A can expand inside the first frame 8 and close the gap between it and the insert 21. In addition, a portion of the sleeve-shaped member 8A is installed so that it is outside the first frame 8. By installing a portion of the sleeve-shaped member 8A outside the first frame 8, in the event of a fire, a portion of the sleeve-shaped member 8A can expand outside the first frame 8 and close the gap between it and the insert 21.

[0106] As shown in Fig. 34, the cover member 6 is installed so that its edge is connected to the outer peripheral surface of the sleeve-shaped member 8A on the side that protrudes outward from the first frame 8. The cover member 6 is fastened to the partition material 100 by adhering it to the outer peripheral surface of the sleeve-shaped member 8A using known fastening means such as adhesives, pressure-sensitive adhesives, adhesive tape, and fastening members such as tackers and screws. Here, the adhesives, pressure-sensitive adhesives, and adhesive tapes are preferably made of non-combustible materials, semi-non-combustible materials, or flame-retardant materials, and it is advisable to blend flame retardants into the adhesives, pressure-sensitive adhesives, etc. The portion of the cover member 6 near the center that covers the first frame 8 and the sleeve-shaped member 8A surrounds the penetrating body 21 so as to be in contact with it, and is fixed to the penetrating body 21 by a string-like member 22 wound around it from the outside. The string-like member 22 may be any bendable member, and is preferably a wire member including a wire. The wire member may be a metal wire alone, or a resin-coated wire such as Nejirikko (registered trademark) in which a metal wire is coated with resin, or a wire and fiber entangled member such as a maul. When a wire member is used, the cover member 6 can be fixed to the penetrating body 21 simply by twisting or twisting it.

[0107] The cover member 6 is preferably installed so as to be in contact with the sleeve-shaped member 8A and the insert 21. By installing the cover member 6 so as to be in contact with the sleeve-shaped member 8A and the insert 21, the opening 101 of the partition material 100 can be blocked by the sleeve-shaped member 8A and the cover member 6, and fire resistance can be improved.

[0108] [Modification 2-1 of the third embodiment] In the modified example 2 of the third embodiment, the first frame 8 has a length that exceeds the thickness of the partition material 100 and is configured to extend outward from the outer surface of one side of the partition material 100. However, in this modified example, the first frame 8 can also have a length that exceeds the thickness of the partition material 100 and extend outward from the outer surfaces of both sides of the partition material 100, similar to the modified example 1-1 shown in Fig. 32. In this modified example, both sides of the partition material 100 can be configured with a fire-resistant structure.

[0109] [Modification 2-2 of the third embodiment] In the second modification of the third embodiment, the partition material 100 is a wall surface of a building, and the configuration of the fire-resistant structure on the wall surface is shown. However, the fire-resistant structure may be a ceiling, floor, etc. of a building, which is a member that separates compartments (first compartment A and second compartment B), as in the first modification 1-2 shown in Fig. 33, and the fire-resistant structure may be configured as a ceiling or floor.

[0110] [Modification 3 of the third embodiment] In the third embodiment, the compartment penetration treatment material in the fireproof structure is configured as the first frame body 8, the sleeve-shaped member 8A, and the cover member 6. However, the compartment penetration treatment material may be configured as the first frame body 8, the sleeve-shaped member 8A, and the fireproof filler material 5, as shown in Fig. 35 .

[0111] As shown in FIG. 36 , the refractory filler 5 is arranged so as to be in contact with at least one of the first frame 8, the sleeve-shaped member 8A, and the inserter 21, and fills at least a part of the gap between the first frame 8, the sleeve-shaped member 8A, and the inserter 21. At this time, at least one of the first frame 8, the sleeve-shaped member 8A, and the inserter 21 functions as a support for supporting the refractory filler 5. By being arranged so as to be in contact with at least one of the first frame 8, the sleeve-shaped member 8A, and the inserter 21 that function as a support, the refractory filler 5 can remain in the gap between the first frame 8, the sleeve-shaped member 8A, and the inserter 21, and can fill the gap between the first frame 8, the sleeve-shaped member 8A, and the inserter 21.

[0112] [Modification 3-1 of the third embodiment] In the third modification of the third embodiment, the first frame 8 has a length that exceeds the thickness of the partition material 100 and is configured to extend beyond the outer surface of one side of the partition material 100. However, in this modification, the first frame 8 can also have a length that exceeds the thickness of the partition material 100 and extend beyond the outer surfaces of both sides of the partition material 100, similar to the first modification 1-1 shown in Fig. 32. In this modification, both sides of the partition material 100 can be configured to have a fire-resistant structure.

[0113] [Modification 3-2 of the third embodiment] In the third modification of the third embodiment, the partition material 100 is a wall surface of a building, and the configuration of the fire-resistant structure on the wall surface is shown. However, the fire-resistant structure may be a ceiling, floor, etc. of a building, which is a member that separates compartments (first compartment A and second compartment B), as in the first modification 1-2 shown in Fig. 33, and the fire-resistant structure may be a configuration of the ceiling or floor.

[0114] [Modification 4 of the third embodiment] In the third embodiment, the compartment penetration treatment material in the fireproof structure is configured as a first frame body 8, a sleeve-shaped member 8A, and a cover member 6. However, as shown in Fig. 37, the compartment penetration treatment material may be configured as a first frame body 8, a sleeve-shaped member 8A, a second frame body 9, and a cover member 6. In this modification, the outer diameter d2 of the second frame body 9 is larger than the outer diameter d1 of the first frame body 8.

[0115] As shown in Fig. 38, the cover member 6 is installed so that its edge is connected to the outer peripheral surface of the second frame body 9. The cover member 6 is fastened to the partition material 100 by adhering it to the outer peripheral surface of the second frame body 9 using known fastening means such as adhesives, pressure-sensitive adhesives, adhesive tape, and fastening members such as tackers and screws. Here, the adhesives, pressure-sensitive adhesives, and adhesive tapes are preferably made of non-combustible materials, semi-non-combustible materials, or flame-retardant materials, and it is advisable to blend flame retardants into the adhesives, pressure-sensitive adhesives, etc. The portion of the cover member 6 that covers the second frame 9 near the center surrounds the penetrating body 21 so as to be in contact with it, and is fixed to the penetrating body 21 by a string-like member 22 that is wound around it from the outside. The string-like member 22 may be any bendable member, and is preferably a wire member that includes a wire. The wire member may be a metal wire alone, or a resin-coated wire such as Nejirikko (registered trademark) in which a metal wire is coated with resin, or a wire and fiber entangled member such as a maul. When a wire member is used, the cover member 6 can be fixed to the penetrating body 21 simply by twisting or twisting it.

[0116] The cover member 6 is preferably installed so as to be in contact with the second frame body 9 and the insert 21. By installing the cover member 6 so as to be in contact with the second frame body 9 and the insert 21, the opening 101 of the partition material 100 can be blocked by the second frame body 9 and the cover member 6, thereby improving fire resistance.

[0117] [Modification 4-1 of the third embodiment] In the fourth modification of the third embodiment, the partition material 100 is a wall surface of a building, and the configuration of the fire-resistant structure on the wall surface is shown. However, the fire-resistant structure may be a ceiling, floor, etc. of a building, which is a member that separates compartments (first compartment A and second compartment B), as in the first modification 1-2 shown in Fig. 33, and the fire-resistant structure may be configured as a ceiling or floor.

[0118] [Modification 5 of the Third Embodiment] In the fourth modification of the third embodiment, the compartment penetration treatment material to be fireproofed in the fireproof treated structure is configured to be the first frame body 8, the sleeve-shaped member 8A, and the cover member 6. However, the compartment penetration treatment material may be configured to further include a fireproof filler 5, as shown in Fig. 39 .

[0119] As shown in Fig. 40, the cover member 6 is installed so that its edge is connected to the outer peripheral surface of the sleeve-shaped member 8A on the side that protrudes outward from the first frame 8. The cover member 6 is fastened to the partition material 100 by adhering it to the outer peripheral surface of the sleeve-shaped member 8A using known fastening means such as adhesives, pressure-sensitive adhesives, adhesive tape, and fastening members such as tackers and screws. Here, the adhesives, pressure-sensitive adhesives, and adhesive tapes are preferably made of non-combustible materials, semi-non-combustible materials, or flame-retardant materials, and it is advisable to blend flame retardants or the like into the adhesives, pressure-sensitive adhesives, etc. The portion of the cover member 6 near the center that covers the first frame 8 and the sleeve-shaped member 8A surrounds the penetrating body 21 so as to be in contact with it, and is fixed to the penetrating body 21 by a string-like member 22 wound around it from the outside. The string-like member 22 may be any bendable member, and is preferably a wire member including a wire. The wire member may be a metal wire alone, or a resin-coated wire such as Nejirikko (registered trademark) in which a metal wire is coated with resin, or a wire and fiber entangled member such as a maul. When a wire member is used, the cover member 6 can be fixed to the penetrating body 21 simply by twisting or twisting it.

[0120] The cover member 6 is preferably installed so as to be in contact with the sleeve-shaped member 8A and the insert 21. By installing the cover member 6 so as to be in contact with the sleeve-shaped member 8A and the insert 21, the opening 101 of the partition material 100 can be blocked by the sleeve-shaped member 8A and the cover member 6, and fire resistance can be improved.

[0121] As shown in Figure 40, the fire-resistant filler 5 is arranged so as to fill at least a portion of the gap between the first frame body 8 and the inserting body 21, and is arranged so as to contact the first frame body 8, the sleeve-shaped member 8A, and the cover member 6. The fireproof filler 5 may be the thermally expandable material described above, or may be a material other than a thermally expandable material as long as it exhibits fire resistance, such as a heat-absorbing material or a heat-insulating material. Examples of the fireproof filler 5 include amorphous materials such as putty, rock wool, glass wool, cellulose fiber, insulation board, gypsum board and board scraps, extruded polystyrene foam, phenolic foam, rigid urethane foam, and non-flammable urethane foam. To improve the handleability of the fireproof filler 5, which is an amorphous material, the fireproof filler 5 may be covered with an exterior material. The exterior material is not particularly limited as long as it is a material that can encapsulate the fireproof filler 5 and maintain the shape of the fireproof filler 5. Examples of the exterior material include metal and resin materials, and from the perspective of flexibility and handleability, a resin film such as a polyolefin resin is preferable. Alternatively, the exterior material may form a bag, and the fireproof filler 5 may be placed inside the bag.

[0122] [Modification 5-1 of the third embodiment] In the fifth modification of the third embodiment, the partition material 100 is a wall surface of a building, and the configuration of the fire-resistant structure on the wall surface is shown. However, the fire-resistant structure may be a ceiling, floor, etc. of a building, which is a member that separates compartments (first compartment A and second compartment B), as in the first modification 1-2 shown in Fig. 33, and the fire-resistant structure may be a configuration of the ceiling or floor.

[0123] [Fourth embodiment] Next, a fourth embodiment of the present invention will be described in detail. As shown in Figures 41 and 42, the compartment penetration treatment material in the fire-resistant structure according to the third embodiment is composed of a first frame body 8, a hat-shaped molding 7, a cover member 6, etc. Below, differences between the third embodiment and the first to third embodiments will be described. Furthermore, parts whose description will be omitted are the same as those in the first to third embodiments. Furthermore, in the following description, members having the same configuration as those in the first to third embodiments will be given the same reference numerals.

[0124] [Hat-shaped molded body] As shown in Figures 41 and 42, the hat-shaped molding 7 has a tubular portion 71 that surrounds the insert 21 in the interior 7A and is inserted into the opening 101, and a flange-like portion 70 that protrudes outward from one end of the tubular portion 71 and is positioned so as to contact the outer surface of the partition material 100. 42, the cylindrical portion 71 has a hollow cylindrical shape with both ends open so that the inserting body 21 can be inserted into the interior 7A. There are no particular limitations on the shape of the cylindrical portion 71 as long as it can be inserted into the opening 101. However, from the viewpoint of improving fire resistance, it is preferable to narrow the gap between the cylindrical portion 71 and the opening 101. Therefore, the cylindrical portion 71 should have a shape similar to that of the opening 101 but reduced in size to allow insertion. The outer diameter d4 of the cylindrical portion 71 is smaller than the outer diameter d1 of the first frame body 8. 42, when the tubular portion 71 is inserted into the opening 101, the flange-shaped portion 70 comes into contact with the outer surface of the partition material 100 and locks onto the entrance side of the opening 101, thereby preventing the flange-shaped portion 70 from falling off. There are no particular restrictions on the shape of the flange-shaped portion 70 as long as it can be locked onto the entrance side of the opening 101. However, from the viewpoint of improving fire resistance, it is preferable to close the gap between the tubular portion 71 and the opening 101, so it is preferable that the flange-shaped portion 70 has an outer diameter larger than that of the opening 101.

[0125] At least one of the cylindrical portion 71 and the flange-shaped portion 70 may be a thermally expandable molded body having thermal expandability. The cylindrical portion 71 and the flange-shaped portion 70 may be molded integrally, or may be molded separately and then integrated.

[0126] The thickness of the cylindrical portion 71 and the flange portion 70 is not particularly limited, but is, for example, 0.1 to 20 mm, and preferably 0.5 to 10 mm. When the thickness 8 of the cylindrical portion 71 and the flange portion 70 is within the above range, the cylindrical portion 71 and the flange portion 70 have appropriate mechanical strength, and the hat-shaped molded body 7 can be well maintained in its installed position relative to the opening 101.

[0127] As shown in Fig. 42, the cover member 6 is installed so that its edge is connected to the surface of the flange-shaped portion 70. The cover member 6 is fastened to the partition material 100 by adhering it to the surface of the flange-shaped portion 70 using known fastening means such as adhesives, pressure-sensitive adhesives, adhesive tape, and fastening members such as tackers and screws. Here, the adhesives, pressure-sensitive adhesives, and adhesive tapes are preferably made of non-combustible materials, semi-non-combustible materials, or flame-retardant materials, and it is advisable to blend flame retardants into the adhesives, pressure-sensitive adhesives, etc. The portion of the cover member 6 near the center that covers the first frame 8 and the hat-shaped body 7 surrounds the inserter 21 so as to be in contact with it, and is fixed to the inserter 21 by a string-like member 22 wound around it from the outside. The string-like member 22 may be any bendable member, and is preferably a wire member including a wire. The wire member may be a metal wire alone, or a resin-coated wire such as Nejirikko (registered trademark) in which a metal wire is coated with resin, or a wire and fiber entangled member such as a maul. When a wire member is used, the cover member 6 can be fixed to the inserter 21 simply by twisting or twisting it.

[0128] The cover member 6 is preferably placed so as to be in contact with the hat-shaped body 7 and the insert 21. By placing the cover member 6 so as to be in contact with the hat-shaped body 7 and the insert 21, the hat-shaped body 7 and the cover member 6 can close the opening 101 of the partition material 100, thereby improving fire resistance.

[0129] [Modification 1 of the Fourth Embodiment] In the fourth embodiment, the partition material 100 is a wall surface of a building, and the configuration of the fire-resistant structure on the wall surface has been shown. However, the fire-resistant structure is a member that separates compartments (a first compartment A and a second compartment B) on the ceiling, floor, etc. of a building, as shown in Fig. 43, and the fire-resistant structure can be configured on the ceiling or floor.

[0130] [Modification 2 of the Fourth Embodiment] In the fourth embodiment, the compartment penetration treatment material in the fireproof structure is configured to include a first frame body 8, a hat-shaped molding 7, and a cover member 6. However, the compartment penetration treatment material may also be configured to further include a second frame body 9, as shown in Fig. 44. In this modification, the outer diameter d2 of the second frame body 9 is larger than the outer diameter d1 of the first frame body 8.

[0131] As shown in Fig. 45, the cover member 6 is installed so that its edge is connected to the outer peripheral surface of the second frame body 9. The cover member 6 is fastened to the partition material 100 by adhering it to the outer peripheral surface of the second frame body 9 using known fastening means such as adhesives, pressure-sensitive adhesives, adhesive tape, and fastening members such as tackers and screws. Here, the adhesives, pressure-sensitive adhesives, and adhesive tapes are preferably made of non-combustible materials, semi-non-combustible materials, or flame-retardant materials, and it is advisable to blend flame retardants into the adhesives, pressure-sensitive adhesives, etc. The portion of the cover member 6 that covers the second frame 9 near the center surrounds the penetrating body 21 so as to be in contact with it, and is fixed to the penetrating body 21 by a string-like member 22 that is wound around it from the outside. The string-like member 22 may be any bendable member, and is preferably a wire member that includes a wire. The wire member may be a metal wire alone, or a resin-coated wire such as Nejirikko (registered trademark) in which a metal wire is coated with resin, or a wire and fiber entangled member such as a maul. When a wire member is used, the cover member 6 can be fixed to the penetrating body 21 simply by twisting or twisting it.

[0132] The cover member 6 is preferably installed so as to be in contact with the second frame body 9 and the insert 21. By installing the cover member 6 so as to be in contact with the second frame body 9 and the insert 21, the opening 101 of the partition material 100 can be blocked by the second frame body 9 and the cover member 6, thereby improving fire resistance.

[0133] [Modification 2-1 of the fourth embodiment] In the second modification of the fourth embodiment, the partition material 100 is a wall surface of a building, and the configuration of the fire-resistant structure on the wall surface is shown. However, the fire-resistant structure may be a ceiling, floor, etc. of a building, which is a member that separates compartments (first compartment A and second compartment B), as in the first modification shown in Fig. 43, and the fire-resistant structure may be a configuration of the ceiling or floor.

[0134] [Modification 3 of the fourth embodiment] In the fourth embodiment, the compartment penetration treatment material in the fireproof structure is configured to include a first frame body 8, a hat-shaped molding 7, and a cover member 6. However, as shown in Fig. 46, the compartment penetration treatment material may also be configured to further include a second frame body 9, and to include a fireproof filler material 5 instead of the cover member 6. In this modified example, the outer diameter d2 of the second frame body 9 is larger than the outer diameter d1 of the first frame body 8.

[0135] As shown in Figure 47, the fire-resistant filler 5 is arranged so as to fill at least a portion of the gap between the first frame body 8 and the inserting body 21, and is arranged so as to contact the second frame body 9, the hat-shaped molding body 7 (brim-shaped portion 70, tubular portion 71) and the cover member 6. The fireproof filler 5 may be the thermally expandable material described above, or may be a material other than a thermally expandable material as long as it exhibits fire resistance, such as a heat-absorbing material or a heat-insulating material. Examples of the fireproof filler 5 include amorphous materials such as putty, rock wool, glass wool, cellulose fiber, insulation board, gypsum board and board scraps, extruded polystyrene foam, phenolic foam, rigid urethane foam, and non-flammable urethane foam. To improve the handleability of the fireproof filler 5, which is an amorphous material, the fireproof filler 5 may be covered with an exterior material. The exterior material is not particularly limited as long as it is a material that can encapsulate the fireproof filler 5 and maintain the shape of the fireproof filler 5. Examples of the exterior material include metal and resin materials, and from the perspective of flexibility and handleability, a resin film such as a polyolefin resin is preferable. Alternatively, the exterior material may form a bag, and the fireproof filler 5 may be placed inside the bag.

[0136] [Modification 3-1 of the fourth embodiment] In the third modification of the fourth embodiment, the partition material 100 is a wall surface of a building, and the configuration of the fire-resistant structure on the wall surface is shown. However, the fire-resistant structure may be a ceiling, floor, etc. of a building, which is a member that separates compartments (first compartment A and second compartment B), as in the first modification shown in Fig. 43, and the fire-resistant structure may be a configuration of the ceiling or floor.

However, as shown in Fig. 48, the compartment penetration treatment material may be configured to include fillers 5A and 5B instead of the fireproof filler 5. In this modification, at least one of the fillers 5A and 5B may be a fireproof material.

[0138] 49, the hat-shaped molded body 7 in this modification is arranged so that the cylindrical portion 71 is not inserted into the opening 101 but protrudes outward from the opening 101. The cylindrical portion 71, which is arranged so as to protrude outward from the opening 101, functions as a support for supporting the filler 5B.

[0139] The fillers 5A and 5B are members that fill at least a part of the gap between the first frame body 8 and the insert 21. As shown in Fig. 49, the filler 5A is arranged so as to fill at least a part of the gap between the first frame body 8 and the insert 21. The filler 5B is arranged so as to fill at least a part of the gap between the first frame body 8 and the insert 21, and is arranged so as to be in contact with the hat-shaped molded body 7 and the second frame body 9.

[0140] [Modification 4-1 of the fourth embodiment] In the fourth modification of the fourth embodiment, the partition material 100 is a wall surface of a building, and the configuration of the fire-resistant structure on the wall surface is shown. However, the fire-resistant structure may be a ceiling, floor, etc. of a building, which is a member that separates compartments (first compartment A and second compartment B), as in the first modification shown in Fig. 43, and the fire-resistant structure may be a configuration of the ceiling or floor.

[0141] [Modification 5 of the Fourth Embodiment] In the fourth embodiment, the compartment penetration treatment material in the fireproof structure is configured to include a first frame body 8, a hat-shaped molding 7, and a cover member 6. However, the compartment penetration treatment material may also be configured to include a fireproof filler material 5 instead of the cover member 6, as shown in Fig. 50.

[0142] 51, the hat-shaped molded body 7 in this modification is arranged so that the cylindrical portion 71 is not inserted into the opening 101 but protrudes outward from the opening 101. The cylindrical portion 71, which is arranged so as to protrude outward from the opening 101, functions as a support for supporting the filler 5B.

[0143] As shown in Figure 51, the refractory filler 5 is arranged so as to fill at least a portion of the gap between the first frame body 8 and the inserting body 21, and is arranged so as to contact the hat-shaped molding body 7 (brim-shaped portion 70, tubular portion 71). The fireproof filler 5 may be the thermally expandable material described above, or may be a material other than a thermally expandable material as long as it exhibits fire resistance, such as a heat-absorbing material or a heat-insulating material. Examples of the fireproof filler 5 include amorphous materials such as putty, rock wool, glass wool, cellulose fiber, insulation board, gypsum board and board scraps, extruded polystyrene foam, phenolic foam, rigid urethane foam, and non-flammable urethane foam. To improve the handleability of the fireproof filler 5, which is an amorphous material, the fireproof filler 5 may be covered with an exterior material. The exterior material is not particularly limited as long as it is a material that can encapsulate the fireproof filler 5 and maintain the shape of the fireproof filler 5. Examples of the exterior material include metal and resin materials, and from the perspective of flexibility and handleability, a resin film such as a polyolefin resin is preferable. Alternatively, the exterior material may form a bag, and the fireproof filler 5 may be placed inside the bag.

[0144] [Modification 5-1 of the fourth embodiment] In the fifth modification of the fourth embodiment, the partition material 100 is a wall surface of a building, and the configuration of the fire-resistant structure on the wall surface is shown. However, the fire-resistant structure may be a ceiling, floor, etc. of a building, which is a member that separates compartments (first compartment A and second compartment B), as in the first modification shown in Fig. 43, and the fire-resistant structure may be a configuration of the ceiling or floor.

[0145] [Other embodiments] The present invention is not limited to the configurations of the above-described first to fourth embodiments, and any improvements and modifications may be made without departing from the technical spirit of the present invention. For example, in the above description, the partition member 100 has a configuration in which there is no hollow space, but as shown in Figures 52 to 54, it may have a hollow portion 102 inside and be made up of a pair of partition members 100A and 100B.

[0146] In the above description, the first frame body 8 is inserted into the opening 101 formed in advance, but the first frame body 8 may also be used as a mold. That is, the first frame body 8 is formed into a sleeve shape so as to have a desired shape for the inner peripheral surface of the opening 101. The first frame body 8 may then be placed at a desired location where the opening 101 is to be formed during the manufacturing stage of the partition material 100, and then poured with concrete so that the outer peripheral surface of the first frame body 8 coincides with and contacts the inner peripheral surface of the opening 101. In this modification, the opening 101 can be formed when the concrete is poured, so the step of forming the opening 101 in the partition material 100 can be omitted. Furthermore, the first frame body 8 can be brought into contact with the opening 101 from one end to the other of the inner peripheral surface of the opening 101, and the outer peripheral surface of the first frame body 8 can also be fixed to the inner peripheral surface of the opening 101, so that the opening 101 can be more reliably closed and fire resistance can be further improved.

[0147] As shown in FIG. 55, the first frame body 8 may be configured to further include a locking portion 10 that contacts the partition material 100 and can determine the installation position of the first frame body 8. The locking portion 10 is locked to the outer periphery of the opening 101 on the outer surface of the partition material 100, and is fixed so as to be able to determine the installation position of the first frame body 8. The shape of the locking portion 10 is not particularly limited, and examples thereof include a block shape, a pillar shape, and a dot shape. The material of the locking portion 10 is not particularly limited as long as it is capable of locking the first frame body 8, and examples thereof include fire-resistant materials, foams, putty materials, and caulking materials, and may also be a composite material made by combining two or more of these. The fire-resistant material is not particularly limited as long as it is a material that has fire resistance, and is preferably a fire-resistant material formed from a thermally expandable resin composition containing the above-mentioned thermally 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 fillers, flame retardants, etc. with synthetic resin materials such as silicone resins, acrylic resins, and urethane resins as the main component.

[0148] From the viewpoint of reducing variations in fire resistance and maintaining sufficient fire resistance, the second frame body 9 is preferably configured to be fixed in close contact with the partition material 100 or the fire-resistant material. The second frame body 9 and the partition material 100 or the fire-resistant material can be fixed in close contact with each other by providing a fixing member such as an adhesive, a magnet, putty, caulking material, or fastening material between the second frame body 9 and the partition material 100 or the fire-resistant material. The adhesive uses, for example, an acrylic adhesive, a urethane adhesive, a rubber adhesive, or a silicone resin adhesive, and fixes the second frame body 9 and the partition material 100 or the fire-resistant material in close contact with each other through adhesive force. The magnet fixes the second frame body 9 and the partition material 100 or the fire-resistant material in close contact with each other through magnetic force. The putty and caulking material fill the gap between the second frame 9 and the partition material 100 or the fireproofing material to tightly fix them together. The fastening material uses screws, tackers, etc. to physically fix the second frame 9 and the partition material 100 or the fireproofing material together to tightly fix them together.

[0149] In the above explanation, the shape of the outer peripheral surface of the first frame body 8 is described as being circular, elliptical, or a shape similar to these, but it may also be rectangular or polygonal as long as it matches the shape of the inner peripheral surface of the opening 101.

[0150] In addition, in the above description, the first to fourth embodiments have been shown as the fire-resistant structure, but the first to fourth embodiments and their modifications may be combined as appropriate. In other words, the embodiments shown in the above description may be combined as appropriate. [Explanation of symbols]
