Abstract
Description
[Technical Field]
[0001] The present invention relates to a fire-resistant structure including a sheet-like positioning material that determines the installation position of a fire-resistant material to be installed in an opening formed in a partition material in a partition section of a building, and a method for manufacturing the fire-resistant structure. [Background technology]
[0002] In buildings such as apartment buildings, office buildings, and schools, compartment penetrations are often installed in partitions such as walls to allow 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, there is variation between workers, and sufficient fire resistance may not be achieved, and the fire resistance may also deteriorate over time. Therefore, a method is known in which a sheet-like fireproofing material is placed in place of an amorphous filler so as to fill the gap between the long insert and the through-hole (see, for example, Patent Document 2). However, the task of determining the position to place the sheet-like fireproofing material is time-consuming, and if the position is inappropriate, sufficient fire resistance may not be obtained.

[0009] The present invention will be described in more detail below using embodiments.
[0010] [First embodiment] (fireproof structure) 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, ceiling, floor, etc. 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 an opening 101 for passing through an inserting member such as a cable or a pipe. The shape of the opening 101 is not particularly limited as long as it allows the inserting member to pass through, and may be, for example, circular, elliptical, rectangular, or a shape similar to these. The opening 101 forms a compartment penetration portion in the partition material 100, and the compartment penetration portion is treated by being blocked with a compartment penetration treatment material. In this embodiment, the compartment penetration treatment material is composed of a sheet-like member 3, a fastening material 6, etc., which will be described later.
[0011] As shown in Figs. 1 and 2, the fire-resistant structure according to the first embodiment of the present invention provides a fire-resistant 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 fire-resistant material is arranged so as to close the gap between the opening 101 and the insert 21. The fire-resistant material is a member that closes at least a portion of the opening 101, constitutes at least a portion of the compartment penetration material, and in this embodiment is constituted by a sheet-like member 3 described below. In the fire-resistant structure, it is preferable that any of the members that constitute the fire-resistant material have a fire-resistant material. The fireproof structure according to the first embodiment of the present invention includes a sheet-like positioning material 1A that determines the installation position of the fireproof material to be installed in the opening 101.
[0012] As shown in Figure 3, the sheet-like positioning material 1A has an opening guide 10A that guides the opening 101 to a specific area 20. In this specification, the "specific area" refers to the area in which the opening 101 should be located in the sheet-like positioning material 1A when the sheet-like positioning material 1A is placed on the partition material 100. The opening guide 10A of this embodiment contains the opening 101, thereby guiding the opening 101 to the specific region 20. Specifically, when the sheet-like positioning material 1A is placed on the partition material 100, the opening guide 10A is placed so as to contain the opening 101, thereby guiding the position of the opening 101 to the specific region 20 of the sheet-like positioning material 1A. The sheet-like positioning material 1A shows the minimum shape of the fireproofing material to be installed on the partition material 100. As shown in Fig. 3, the sheet-like positioning material 1A is arranged on the partition material 100 so that the opening 101 is contained within the opening guide 10A, thereby making it possible to show the state in which the opening 101 is located in the specific area 20 and indicate the installation position of the fireproofing material.
[0013] The opening guide 10A is in the form of a hole having a length exceeding the longest portion D of the opening 101. The hole is preferably one size larger than the opening 101 so that the entire opening 101 can be accommodated therein. In other words, the hole is preferably large enough that when the hole is placed inside the opening 101, a predetermined distance is formed between the hole and the opening 101 along the entire circumference of the opening 101. The shape of the hole is preferably circular, but is not particularly limited as long as the length L described below can be ensured, and may be polygonal such as a square, elliptical, or another shape. The longest portion D of the opening 101 refers to the diameter if the opening 101 is circular, and refers to the longest inner diameter if the opening 101 is not circular.
[0014] The sheet-like positioning material 1A has a slit 16 extending from the opening guide 10A to the outer edge of the sheet-like member 3. The sheet-like positioning material 1A has the slit 16, which allows the inserting body 21 to be inserted into the hole serving as the opening guide 10A.
[0015] In order to indicate the minimum shape of the fireproofing material to be installed in the partition material 100, the sheet-like positioning material 1A has an area outside the specific area 20, which is a minimum length L over which the fireproofing material should be installed from the edge of the opening 101. In other words, by arranging the sheet-like positioning material 1A in the partition material 100 so that the opening 101 is enclosed within the opening guide 10A, it is possible to ensure the minimum length L over which the fireproofing material should be installed from the edge of the opening 101. The minimum length L over which the fireproofing material should be installed from the edge of the opening 101 may be any value specified when the compartment penetration structure in which the opening 101 is provided is made a fireproof structure, and may be, for example, 5 to 30 mm, preferably 10 to 20 mm.
[0016] The sheet-like positioning material 1A can be made of at least one material selected from the group consisting of resin sheets such as polyolefin resins, vinyl chloride resins, polycarbonate resins, urethane resins, styrene resins, and phenolic resins; rubber sheets such as synthetic rubber; metal sheets such as metal foils and metal plates; and glass fiber composites. Among these, a resin sheet is preferred because it makes it easy to make the sheet-like positioning material 1A transparent, allowing the sheet-like positioning material 1A to be visually recognized when being placed on the partition material 100. The sheet-like positioning material 1A is made of a single sheet (hereinafter also referred to as a "guide sheet") and is preferably rectangular, although not particularly limited thereto.
[0017] The sheet-like positioning material 1A is provided with a position guide 11 that indicates the installation position of the fireproofing material to be installed on the partition material 100. Since the sheet-like positioning material 1A indicates the minimum shape of the fireproofing material to be installed on the partition material 100, the outer periphery of the sheet-like positioning material 1A can serve as the position guide 11, and the position guide 11 on the sheet-like positioning material 1A is the outer periphery that constitutes the sheet-like positioning material 1A. In other words, by placing the sheet-like positioning material 1A on the partition material 100, it is possible to indicate the installation position 102 of the fireproofing material on the partition material 100.
[0018] The partition material 100, which has an opening 101 formed therein and through which the insert 21 is inserted, is subjected to fireproofing by arranging a fireproofing material (sheet-like member 3) at a position positioned by the sheet-like positioning material 1A, and installing it so as to close the gap between the opening 101 and the insert 21, as shown in Fig. 2. In this embodiment, the fireproofing material installed in the partition material 100 is the sheet-like member 3, and the target of the installation position 102 indicated by the sheet-like positioning material 1A is the sheet-like member 3.
[0019] The sheet-shaped member 3 is a member that closes at least a part of the gap between the opening 101 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 a free end. With this configuration, when the inserter 21 is inserted through the center of the sheet-shaped member 3, each segment 31 is easily positioned along the outer periphery of the inserter 21, making it possible to efficiently close the gap inside the opening 101. As shown in FIG. 2 , 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 and installing fastening members 6 into the partition material 100 from above the sections of the sheet-like member 3 other than the sections 31. The fastening members 6 may be fixing members such as screws or tackers that are installed from the outside of the sheet-like member 3. The sheet-like member 3 closes at least a portion of the gap between the opening 101 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 opening 101 and the insert 21 with the sections 31 and other sections. By placing the sections 31 and other sections of the sheet-like member 3 in contact with the outer periphery of the partition material 100 and the insert 21, fire resistance can be improved. The sheet-like member 3 may have at least one layer selected from the group consisting of a base material, an adhesive layer, a cushion layer, and a fire-resistant material layer. There are no particular limitations on the sheet-like member 3 as long as it has a layer containing at least one of a fire-resistant material and a non-combustible material, but in this embodiment, it is sufficient that at least one layer contains 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.
[0020] The fire-resistant material constituting the fire-resistant material layer is a thermally expandable material that expands when heated. The thermally expandable material prevents the spread of fire by expanding in the event of a fire. The thermally expandable material is preferably formed from a thermally expandable resin composition, as described below. The 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.
[0021] The substrate imparts rigidity to the sheet-like member, improving the ease of handling of the sheet-like member and the ability to maintain its installation position. When the tape-like member 6 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 the substrate include metal foils such as aluminum foil and copper foil, metal foil composites such as glass cloth and composites of metal foil and glass cloth such as aluminum-glass cloth, paper, cloth, and resin film. Among these, from the viewpoint of fire resistance, it is preferable that the substrate is made of a non-combustible material, and preferred specific examples include metal foil and metal foil composites.
[0022] 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.
[0023] 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 tape-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, and 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. When the adhesive layer is disposed as the outermost layer, it functions to adhere the sheet-like member itself to other members (e.g., partition materials, etc.), and when disposed as an inner layer, it functions to bond adjacent layers to each other. 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, and silicone resin adhesives. 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] According to the fire-resistant treatment structure of this embodiment, the sheet-like positioning material 1A can be used to identify the installation position 102 of the fire-resistant treatment material to be installed in the opening 101 formed in the partition material 100 in the partition section of a building, and the fire-resistant treatment material can be reliably installed at the identified position to perform fire-resistant treatment.Therefore, in the partition material 100 having the opening 101, variation in fire resistance performance can be reduced and sufficient fire resistance performance can be maintained. Furthermore, according to the fireproofing structure of this embodiment, the opening guide 10A of the sheet-like positioning material 1A is in the form of a hole, so even if the opening 101 has an insert 21 inserted therethrough, the installation position 102 of the fireproofing material to be installed in the opening 101 can be identified, and the fireproofing material can be reliably installed at the identified position to perform fireproofing.
[0025] (Method of manufacturing fireproof structure) In the method for manufacturing a fireproof structure according to the first embodiment of the present invention, first, a sheet-like positioning material 1A is prepared, which includes an opening guide 10A that guides an opening 101 to a specific region 20. Next, the sheet-like positioning material 1A is placed on a partition material 100 so that the opening guide 10A positions the opening 101 in the specific region 20 of the sheet-like positioning material 1A. Specifically, in this embodiment, the sheet-like positioning material 1A is placed on the partition material 100 so that the opening guide 10A encloses the opening 101. At this time, it is preferable to place the sheet-like positioning material 1A on the partition material 100 so that the entire opening 101 is enclosed within the hole in the opening guide 10A. However, from the viewpoint of determining the installation position 102 of the fireproofing material in a more desirable position, it is preferable to place the sheet-like positioning material 1A on the partition material 100 so that the center of the hole constituting the opening guide 10A coincides as closely as possible with the center of the opening 101.
[0026] Next, the installation position 102 for the fireproofing material is specified by the sheet-like positioning material 1A placed on the partition material 100. Then, the fireproofing material is installed at the installation position 102 specified by the sheet-like positioning material 1A, and the fireproofing material is used to close the gap between the opening 101 and the insert 21 inserted into the opening 101. Specifically, the installation position 102 indicated by the position guide 11 of the sheet-like positioning material 1A can be determined as the installation position 102 for the sheet-like member 3, and the sheet-like member 3 is installed at that installation position 102, and the sheet-like member 3 is then fireproofed so as to close the gap between the opening 101 and the insert 21. By going through the above steps, the sheet-like positioning material 1A can be used to determine the installation position 102 of the fire-resistant treatment material to be installed in the opening 101 formed in the partition material 100 in the partition section of the building, and the fire-resistant treatment material can be reliably installed at the specified position to perform fire-resistant treatment.
[0027] According to the manufacturing method of the fire-resistant structure of this embodiment, it becomes easier to identify the installation position 102 of the fire-resistant material to be installed in the opening 101 formed in the partition material 100 in the partition section of the building, thereby making the fire-resistant treatment easier.
[0028] (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.
[0029] 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.
[0030] 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.
[0031] 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.
[0032] 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.
[0033] 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.
[0034] 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.
[0035] 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.
[0036] 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.
[0037] 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.
[0038] 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.
[0039] The thermally expandable resin composition may contain a known tackifier, which makes it easier to impart tackiness to the thermally expandable member. Furthermore, the thermally expandable resin composition used in the present invention may contain additives commonly used in thermally expandable resin compositions, such as heat stabilizers, lubricants, processing aids, antioxidants, antistatic agents, pigments, crosslinking agents, crosslinking accelerators, etc., as needed, within the range that does not impair the physical properties of the composition. Among these, it is preferable to use processing aids.
[0040] 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.
[0041] [Modification 1 of the First Embodiment] In the first embodiment, the fireproofing material used for fireproofing in the fireproofing structure is a sheet-shaped member 3. However, as shown in Fig. 4, the fireproofing material may also be configured to further include a tape-shaped member 4. It is preferable that either the sheet-shaped member 3 or the tape-shaped member 4 has a fireproof material.
[0042] The tape-shaped member 4 is a member that closes at least a part of the gap between the opening 101 and the inserting body 21. As shown in Fig. 5, the tape-shaped member 4 is arranged so as to cover a part of the sheet-shaped member 3 and 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 retention of the installation position 102, 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 have a configuration including at least one layer selected from the group consisting of a substrate, an adhesive layer, a cushion layer, and a fire-resistant material layer. The details of the substrate, adhesive layer, cushion layer, and fire-resistant material layer are as described above. The tape-shaped member 4 is not particularly limited as long as it has a configuration including a layer containing at least one of a fire-resistant material and a non-combustible material, but it is sufficient that at least one layer contains at least one of a fire-resistant material and a non-combustible material, and it is preferable that the tape-shaped member 4 contains a fire-resistant material. The non-combustible material is defined in the Building Standards Act and the Enforcement Order of the Building Standards Act. 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.
[0043] [Modification 2 of the First Embodiment] In the first embodiment, the compartment treatment material to be fireproofed in the fireproof structure is the sheet-like member 3. However, the fireproof treatment material may be configured to further include a fireproof filler 5, as shown in FIG.
[0044] The refractory filler 5 is a member that fills at least a part of the gap between the opening 101 and the insert 21. As shown in Fig. 7 , the refractory filler 5 is arranged so as to fill at least a part of the gap between the opening 101 and the insert 21, and is arranged so as to be in contact with the sheet-like member 3. 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.
[0045] [Modification 3 of the First Embodiment] In the first embodiment, the compartment treatment material to be fireproofed in the fireproof structure is the sheet-like member 3. However, the fireproof treatment material may be configured to further include a cover member 7A, as shown in FIG.
[0046] The cover member 7A is provided to be connected to the sheet-shaped member 3 and is a member that closes at least a portion of the gap between the sheet-shaped member 3 and the insert 21 (21A, 21B). For example, as shown in FIG. 8, the cover member 7A is provided to be connected to the sheet-shaped member 3, and four cover members 7A are used to connect to the four side edges of the sheet-shaped member 3, forming four extension portions extending outward from the sheet-shaped member 3. With this configuration, by connecting the four extension portions of the cover member 7A to the sheet-shaped member 3, the sheet-shaped member 3 and the cover member 7A can be installed as a single unit. Furthermore, it is not necessary to use four cover members 7A as described above, and a structure in which one cover member 7A is connected to the sheet-shaped member 3 may be used. Examples of means for connecting the cover member 7A to at least a portion of the sheet-like member 3 include means for fixing by known fixing means such as adhesives, pressure-sensitive adhesives, and adhesive tapes, as well as fixing members such as tackers and screws.
[0047] 9, the cover member 7A is preferably placed so as to be in contact with the sheet-like member 3 and the insert 21. By placing the cover member 7A so as to be in contact with the sheet-like member 3 and the insert 21, the opening 101 of the partition material 100 can be blocked by the sheet-like member 3 and the cover member 7A, thereby improving fire resistance. As shown in FIG. 9, the cover member 7A surrounds the outer peripheral surface of the penetrating body 21 so as to contact the outer peripheral surface of the penetrating body 21, 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 7A can be fixed to the penetrating body 21 simply by twisting or twisting it.
[0048] The cover member 7A 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 a non-combustible material layer. Furthermore, the cover member 7A 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 7A 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. As described above, the cover member 7A is preferably a sheet that can be deformed to cover the sheet-like member 3, and is preferably thinner than the sheet-like member 3 so that it is flexible and can be easily deformed. The thickness of the cover member 7A is not particularly limited, but is, for example, 0.01 to 1 mm, and preferably 0.05 to 0.5 mm.
[0049] [Fourth Modification of the First Embodiment] In the first embodiment, the compartment treatment material to be fireproofed in the fireproof structure is the sheet-like member 3. However, the fireproof treatment material may also be configured to further include a cover member 7B, as shown in Fig. 10. In this modification, the sheet-like member 3 and the cover member 7B are prepared as separate members before construction.
[0050] The cover member 7B is provided so as to contact the sheet-shaped member 3, and is a member that closes at least a part of the gap between the sheet-shaped member 3 and the inserting body 21 (21A, 21B). The cover member 7B includes a covering portion 7a that is arranged so as to cover the sheet-shaped member 3, and a cylindrical portion 7b that is provided so as to be connected to the covering portion 7a. The covering portion 7a and the cylindrical portion 7b of the cover member 7B may be integral, or may be separate and connected to each other.
[0051] 11, the cover member 7B is installed so that the covering portion 7a contacts the sheet-like member 3, and the cylindrical portion 7b contacts the insert 21. By installing the cover member 7B so that it contacts the sheet-like member 3 and the insert 21, the opening 101 of the partition material 100 can be blocked by the sheet-like member 3 and the cover member 7B, thereby improving fire resistance. Examples of means for connecting the covering portion 7a of the cover member 7B to the sheet-like member 3 include means for fixing by known fixing means such as adhesives, pressure-sensitive adhesives, and adhesive tapes, as well as fixing members such as tackers and screws. In addition, the cover member 7B may be formed as an integrated part with the sheet-like member 3 by connecting the covering portion 7a and the sheet-like member 3 in advance, and by forming them as an integrated part, the sheet-like member 3 and the cover member 7B can be installed as a single unit.
[0052] As shown in FIG. 11, the cylindrical portion 7b of the cover member 7B is fixed to the penetrating body 21 by a string-like member 22 that surrounds the penetrating body 21 so as to contact the outer peripheral surface of the penetrating body 21 and is wound around 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, 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 cylindrical portion 7b of the cover member 7B can be fixed to the penetrating body 21 simply by twisting or twisting it.
[0053] The covering portion 7a and the cylindrical portion 7b of the cover member 7B may be made of a single layer of fire-resistant material, a single layer of non-combustible material, or both a fire-resistant layer and a non-combustible material layer, but preferably have a non-combustible material layer, and more preferably a non-combustible material layer. Furthermore, they may have layers other than the fire-resistant layer and the non-combustible material layer, such as a material layer made of a material other than a non-combustible material, an adhesive layer, etc. The covering portion 7a and the cylindrical portion 7b of the cover member 7B are preferably made of a metal foil such as aluminum foil, glass cloth, or a metal foil composite that is a composite of a metal foil and a glass cloth such as aluminum glass cloth. These constitute the non-combustible material layer. Among these, aluminum glass cloth is more preferable from the viewpoint of fire resistance. As described above, the covering portion 7a and the cylindrical portion 7b of the cover member 7B are preferably sheets that can be deformed to cover the sheet-like member 3 and the inserting body 21, and are preferably thinner than the sheet-like member 3 so as to be flexible and to facilitate deformation. The thickness of the cover member 7B is not particularly limited, but is, for example, 0.01 to 1 mm, and preferably 0.05 to 0.5 mm.
[0054] [Fifth Modification of the First Embodiment] In the first embodiment, the fireproofing material used for fireproofing in the fireproofing structure is a sheet-like member 3. However, the fireproofing material may be a tape-like member 4 instead of the sheet-like member 3, as shown in FIG.
[0055] The tape-shaped member 4 is a member that surrounds and covers the insert 21, and as shown in Fig. 13, an end portion 4A formed by surrounding and covering the insert 21 closes at least a part of the gap between the opening 101 and the insert 21. The tape-shaped member 4 may be installed by wrapping it around the outer periphery of the insert 21 multiple times so that the end portion 4A fills the area of the fireproofing material to be installed in the partition material 100 indicated by the sheet-like positioning material 1A. The tape-shaped member 4 may have at least one layer selected from the group consisting of a substrate, an adhesive layer, a cushion layer, and a fire-resistant layer. There are no particular limitations on the tape-shaped member 4 as long as it has a layer containing at least one of a fire-resistant material and a non-combustible material, but it is sufficient that at least one layer contains at least one of a fire-resistant material and a non-combustible material, and it is preferable that the tape-shaped member 4 contains a fire-resistant material. The non-combustible material is defined in the Building Standards Act and the Enforcement Order of the Building Standards Act. 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.
[0056] [Modification 6 of the First Embodiment] In the first embodiment, the fireproofing material used for fireproofing in the fireproofing structure is the sheet-like member 3. However, as shown in Fig. 14, the fireproofing material may be configured to include a cover member 7B and a sleeve 8 instead of the sheet-like member 3. The sleeve 8 may be configured to include a thermally expandable member 80.
[0057] 15, the sleeve 8 is inserted into the opening 101 and disposed in the opening 101 so that the insert 21 passes through the opening 101. The end of the sleeve 8 may extend outside the opening 101 (i.e., the outer surface of the partition member 100). The sleeve 8 may be made of metal, resin, paper, or the like. The sleeve 8 may be sleeve-shaped and insertable into the opening 101. It may be formed from a steel material or a sheet-shaped fire-resistant material with its ends facing each other. When forming the sheet-shaped fire-resistant material into a sleeve, the ends are faced each other, and the ends may be bonded together using 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. The adhesive tape includes a substrate and an adhesive layer provided on one side of the substrate. The substrate and the adhesive layer may each be made of a non-combustible material, a quasi-non-combustible material, or a flame-retardant material. However, the sleeve 8 is not limited to being faced with its ends facing each other; it may be formed into a sleeve shape with its ends overlapping each other. The thickness of the sleeve 8 is not particularly limited, but is, for example, 0.2 to 10 mm, and preferably 0.5 to 6 mm.
[0058] The sleeve 8 is formed into a sleeve shape so as to fit the shape of the inner peripheral surface of the opening 101. That is, the sleeve 8 is formed into 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 sleeve 8 is in contact with the inner peripheral surface of the opening 101. Since the shape of the inner peripheral surface of the opening 101 is generally a circle, an ellipse, or a shape similar to these, the sleeve 8 may be rounded into a sleeve shape, and may be formed into a circle, an ellipse, or a shape similar to these.
[0059] The thermally expandable expansion member 80 installed in the sleeve 8 is installed, for example, so as to be in contact with the inner wall portion of the sleeve 8. By inserting the sleeve 8 having the thermally expandable expansion member 80 installed on its inner wall portion into the opening 101, the thermally expandable expansion member 80 is installed so that at least a portion of it is present inside the opening 101. By placing the sleeve 8 and the thermally expandable expansion member 80 in contact with each other inside the opening 101, in the event of a fire the thermally expandable expansion member 80 can expand inside the sleeve 8 and close the gap between it and the insert 21. The sleeve 8 may be formed into a sleeve shape and then the thermally expandable expansion member 80 may be installed on the inner wall portion, or the thermally expandable expansion member 80 may be installed before the sleeve is formed, and the thermally expandable expansion member 80 may be installed on the inner wall portion by forming the sleeve shape integrally with the thermally expandable expansion member 80.
[0060] 15, the cover member 7B is provided so as to be in contact with the sheet-like positioning material 1A and the insert 21, and is a member that blocks at least a part of the gap between the opening 101 and the insert 21. The cover member 7B includes a covering portion 7a that is arranged so as to cover the sheet-like positioning material 1A, and a cylindrical portion 7b that is provided so as to be connected to the covering portion 7a. The covering portion 7a and the cylindrical portion 7b of the cover member 7B may be integral, or may be separate and connected together.
[0061] 15, the cover member 7B is installed so that the covering portion 7a contacts the sheet-like positioning material 1A, and the cylindrical portion 7b contacts the insert 21. By installing the cover member 7B so that it contacts the sheet-like positioning material 1A and the insert 21, the cover member 7B can close the opening 101 of the partition material 100, thereby improving fire resistance. Examples of means for connecting the covering portion 7a of the cover member 7B to the sheet-like member 3 include means for fixing by known fixing means such as adhesives, pressure-sensitive adhesives, and adhesive tapes, as well as fixing members such as tackers and screws. In addition, the cover member 7B may be formed as an integrated part with the sheet-like member 3 by connecting the covering portion 7a and the sheet-like member 3 in advance, and by forming them as an integrated part, the sheet-like member 3 and the cover member 7B can be installed as a single unit.
[0062] As shown in FIG. 15, the cylindrical portion 7b of the cover member 7B is fixed to the penetrating body 21 by a string-like member 22 that surrounds the penetrating body 21 so as to contact the outer peripheral surface of the penetrating body 21 and is wound around 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, 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 cylindrical portion 7b of the cover member 7B can be fixed to the penetrating body 21 simply by twisting or twisting it.
[0063] The covering portion 7a and the cylindrical portion 7b of the cover member 7B may be made of a single layer of fire-resistant material, a single layer of non-combustible material, or both a fire-resistant layer and a non-combustible material layer, but preferably have a non-combustible material layer, and more preferably a non-combustible material layer. Furthermore, they may have layers other than the fire-resistant layer and the non-combustible material layer, such as a material layer made of a material other than a non-combustible material, an adhesive layer, etc. The covering portion 7a and the cylindrical portion 7b of the cover member 7B are preferably made of a metal foil such as aluminum foil, glass cloth, or a metal foil composite that is a composite of a metal foil and a glass cloth such as aluminum glass cloth. These constitute the non-combustible material layer. Among these, aluminum glass cloth is more preferable from the viewpoint of fire resistance. As described above, the covering portion 7a and the cylindrical portion 7b of the cover member 7B are preferably sheets that can be deformed to cover the sheet-like positioning material 1A and the inserting body 21, and are preferably thinner than the sheet-like member 3 so as to be flexible and to facilitate deformation. The thickness of the cover member 7B is not particularly limited, but is, for example, 0.01 to 1 mm, and preferably 0.05 to 0.5 mm.
[0064] [Seventh Modification of the First Embodiment] In the first embodiment, the fireproofing material used in the fireproofing structure is the sheet-shaped member 3. However, the fireproofing material may be configured to include a hat-shaped molded body and a fireproof filler 5 instead of the sheet-shaped member 3, as shown in Fig. 16 .
[0065] As shown in Figures 16 and 17, the hat-shaped molded body 9 has a tubular portion 91 that surrounds the insert 21 inside 9A and is inserted into the opening 101, and a flange-like portion 90 that protrudes outward from one end of the tubular portion 91 and is positioned so as to contact the sheet-like positioning material 1A. 16, cylindrical portion 91 has a hollow cylindrical shape with both ends open so that inserter 21 can be inserted into interior 9A. There are no particular limitations on the shape of cylindrical portion 91 as long as it can be inserted into opening 101. However, from the viewpoint of improving fire resistance, it is preferable to narrow the gap between cylindrical portion 91 and opening 101, so it is preferable that the shape be similar to opening 101 and reduced to an extent that it can be inserted. 16, when the cylindrical portion 91 is inserted into the opening 101, the flange-shaped portion 90 comes into contact with the sheet-like positioning material 1A installed on the partition material 100 and locks onto the entrance side of the opening 101, thereby preventing it from falling off. There are no particular restrictions on the shape of the flange-shaped portion 90 as long as it can be locked onto the entrance side of the opening 101, but from the perspective of improving fire resistance, it is preferable to close the gap between the cylindrical portion 91 and the opening 101, so it is preferable for the flange-shaped portion 90 to have a shape with an outer diameter larger than the opening 101.
[0066] At least one of the cylindrical portion 91 and the flange-shaped portion 90 may be a thermally expandable molded body having thermal expandability. The cylindrical portion 91 and the flange-shaped portion 90 may be molded integrally, or may be molded separately and then integrated.
[0067] The thickness of the cylindrical portion 91 and the flange portion 90 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 91 and the flange portion 90 is within the above range, the cylindrical portion 91 and the flange portion 90 have appropriate mechanical strength, and the hat-shaped molded body 9 can be well maintained in the installation position 102 relative to the opening 101.
[0068] 17 , the refractory filler 5 is arranged so as to be in contact with at least one of the cylindrical portion 91 and the flange portion 90 of the hat-shaped body 9, and seals at least a portion of the gap between the hat-shaped body 9 and the insert 21. At this time, at least one of the cylindrical portion 91 and the flange portion 90 of the hat-shaped body 9 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 cylindrical portion 91 and the flange portion 90 of the hat-shaped body 9, which function as a support, the refractory filler 5 can remain in the gap between the hat-shaped body 9 and the insert 21 and seal the gap between the hat-shaped body 9 and the insert 21.
[0069] [Variation 8 of the First Embodiment] In the first embodiment, as shown in Fig. 3, the sheet-like positioning material 1A has an opening guide 10A in the form of a hole having a length that exceeds the longest part D of the opening 101. However, as shown in Fig. 18, the sheet-like positioning material 1B may have an opening guide 10B in the form of a notch having a length that exceeds the longest part D of the opening 101.
[0070] The sheet-like positioning material 1B in this modification has a notch cut out from one side of the outer periphery that constitutes the sheet-like positioning material 1B, and the notch forms an opening guide 10B. Opening guide 10B has inner packet part 10b1 which forms part of the circumference, and connecting part 10b2 which connects one side of the outer periphery of sheet-like positioning material 1B to inner packet part 10b1. Opening guide 10B contains opening 101 within the circumferential range formed by inner packet part 10b1, which forms part of the circumference, thereby guiding opening 101 to specific area 20. Specifically, when placing sheet-like positioning material 1A on partition material 100, opening guide 10B is positioned so that opening 101 is contained within the circumferential range formed by inner packet part 10b1, which forms part of the circumference, thereby guiding the position of opening 101 to specific area 20 of sheet-like positioning material 1B. In this variation, the entire opening 101 can be contained within the cutout. Therefore, when the opening 101 is positioned within the inner packet part 10b1, the opening 101 should be large enough to create a predetermined distance between the inner packet part 10b1 and the opening 101 around the entire circumference of the inner packet part 10b1, and the entire opening 101 should fit within the cutout. The outer periphery of the non-cutout part of the sheet-like positioning material 1B indicates the installation position 102 of the fireproofing material to be installed on the partition material 100. As shown in Figure 18, the sheet-like positioning material 1B is positioned on the partition material 100 so that the opening 101 is located within the inner packet part 10b1 of the opening guide 10B, making it possible to indicate the installation position 102 of the three sides of the fireproofing material while showing that the opening 101 is located in the specific area 20. In this variation, inner packet part 10b1 is made up of a curve that forms part of the circumference, and connecting part 10b2 is made up of a straight line, but the shape of inner packet part 10b1 does not have to form part of the circumference as long as opening 101 is contained inside inner packet part 10b1. Furthermore, connecting part 10b2 does not have to be made up of a straight line, and may include a curve as appropriate.
[0071] [Modification 9 of the First Embodiment] In the first embodiment, as shown in Fig. 3, the sheet-like positioning material 1A has an opening guide 10A in the form of a hole having a length that exceeds the longest part D of the opening 101. However, as shown in Fig. 19, the sheet-like positioning material 1C may have an opening guide 10C in the form of a notch having a length that exceeds the longest part D of the opening 101.
[0072] The sheet-like positioning material 1C in this modified example has a notch in a part of the outer periphery that constitutes the sheet-like positioning material 1C, and the notch constitutes an opening guide 10C. Opening guide 10C is made up of inner packet part 10c1, which forms part of the circumference. Opening guide 10C guides opening 101 to specific area 20 by containing opening 101 within the circumferential range formed by inner packet part 10c1, which forms part of the circumference (for example, a semicircle). Specifically, opening guide 10B is positioned so that opening 101 is contained within the circumferential range formed by inner packet part 10c1, which forms part of the circumference, when sheet-like positioning material 1A is placed on partition material 100, thereby guiding the position of opening 101 to specific area 20 of sheet-like positioning material 1C. Also, in this variation 2, only part of opening 101 can be contained within the notch. Therefore, it is preferable that the length of the notch (inner packet part 10c1) in one direction (X direction) is longer than the diameter of opening 101, but shorter than the diameter of opening 101 in the direction perpendicular to that direction (Y direction). However, it is preferable that the direction perpendicular to the one direction (Y direction) is longer than half the diameter of opening 101. By having a certain length in the Y direction, for example, more than half of the area of opening 101 can be contained within the cutout, so that even a small cutout can be accurately positioned. One side of the sheet-like positioning material 1C that does not have a cutout indicates the position of one side of the fire-resistant material to be installed on the partition material 100, and the two sides adjacent to the one side that does not have a cutout indicate the positions of the two sides of the fire-resistant material to be installed on the partition material 100. As shown in Figures 19 and 20, by placing the sheet-like positioning material 1C on the partition material 100 so that the opening 101 is positioned in the opening guide 10C, it is possible to indicate the installation position 102 of one side of the fire-resistant material while showing that the opening 101 is positioned in the specific region 20. In this modified example, the inner container part 10b1 is shown as being made up of a curve that forms part of the circumference, but the shape of the inner container part 10b1 does not need to form part of the circumference as long as the opening 101 is contained inside the inner container part 10b1.
[0073] [Modification 10 of the First Embodiment] In the first embodiment, as shown in Fig. 3, the sheet-like positioning material 1A has an opening guide 10A in the form of a hole having a length that exceeds the longest part D of the opening 101. However, as shown in Fig. 21, the sheet-like positioning material 1D may have an opening guide 10D in the form of a slit having a length that exceeds the longest part D of the opening 101.
[0074] The sheet-like positioning material 1D in this modification has a plurality of slits 10d1 and 10d2 extending from one side of the outer periphery that constitutes the sheet-like positioning material 1D, and the slits 10d1 and 10d2 constitute opening guides 10D. The opening guide 10D has one slit 10d1 that extends from an end of the specific region 20, across the specific region 20, to the outer edge of the sheet-like positioning material 1D, and another slit 10d2 that intersects at a point in the central portion 20c of the specific region 20. The opening guide 10D guides the opening 101 into the specific region 20 by including the opening 101 within a circumferential range that is centered on the central portion 20c and has the slit 10d2 as its diameter. Specifically, when the sheet-like positioning material 1D is placed on the partition material 100, the opening guide 10D is positioned so that the opening 101 is included within a circumferential range that is centered on the central portion 20c and has the slit 10d2 as its diameter, thereby guiding the position of the opening 101 into the specific region 20 of the sheet-like positioning material 1D. In this modified example, the sheet-like positioning material 1D is made transparent, so that the position of the opening 101 can be easily guided to the specific region 20 of the sheet-like positioning material 1D while visually checking the opening 101 and the slits 10d1 and 10d2. The sheet-like positioning material 1D shows the minimum shape of the fireproofing material to be installed in the partition material 100. As shown in Fig. 21, the sheet-like positioning material 1D is arranged in the partition material 100 so that the opening 101 is located within a circumferential range with the slit 10d2 as the diameter and the central portion 20c of the opening guide 10D as the center, thereby making it possible to show the state in which the opening 101 is located in the specific region 20 and to show the installation position 102 of the fireproofing material.
[0075] [Second embodiment] Next, a second embodiment of the present invention will be described in detail. The sheet-like positioning material 1E in the fire-resistant structure according to the second embodiment differs from the sheet-like positioning material 1A in the fire-resistant structure according to the first embodiment in that it further includes an adhesive portion 12, as shown in FIG. 22. The following describes the differences between the second embodiment and the first embodiment. Furthermore, parts whose description is omitted are the same as those in the first embodiment. Furthermore, in the following description, parts having the same configuration as those in the first embodiment are given the same reference numerals.
[0076] The adhesive portion 12 is provided at one end 15 that constitutes one side of the sheet-like positioning material 1F, and is the portion that adheres the sheet-like positioning material 1E to the partition section 100 when the sheet-like positioning material 1E is placed in the partition section 100. The adhesive portion 12 has an adhesive layer on its outermost layer, and functions to adhere the sheet-like positioning material 1E to the partition section 100. 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, and silicone resin adhesives. 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. After being adhered to the partition section 100, the adhesive section 12 can be peeled off from the partition section 100. Therefore, the adhesive section 12 can adhere the sheet-like positioning material 1E to the partition section 100 and temporarily fix it thereto.
[0077] The sheet-like positioning material 1E has a folding portion 13 provided on one end 15 where the adhesive portion 12 is provided, on the side of the adhesive portion 12. The folding portion 13 is formed by a crease, a groove, or the like. As shown in Fig. 23 , after the sheet-like positioning material 1F is adhered to the partition portion 100 by the adhesive portion 12, the sheet-like positioning material 1E can be folded from the folding portion 13 as a starting point to the side opposite to the side where the adhesive portion 12 is provided, i.e., away from the partition portion 100. The side on the one end 15 side indicates the installation position 102 of one side of the fireproofing material to be installed on the partition material 100, and can therefore serve as the position guide 11 in the sheet-like positioning material 1E. That is, as shown in Fig. 24, the position guide 11 in the sheet-like positioning material 1E is one side that serves as the starting point of the folding portion 13, and by installing the fireproofing material in accordance with this location, the fireproofing material can be installed in the predetermined installation position 102.
[0078] 24 and 25, the fireproof structure according to this embodiment 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 opening 101 and the insert 21. In this embodiment, the fireproof material is made up of a sheet-like member 3, a fastening material 6, etc.
[0079] According to the sheet-like positioning material 1E of the fire-resistant structure of this embodiment, it is possible to obtain the same effects as the sheet-like positioning material 1A of the fire-resistant structure of the first embodiment. According to the sheet-like positioning material 1E with a fire-resistant structure of this embodiment, one side folded at the folding portion 13 serves as a position guide 11, so it is possible to omit marking the installation position 102 of the fire-resistant material on the partition material 100, or otherwise indicating this. In this embodiment, the sheet-like positioning material 1E does not need to have creases, grooves, etc., as long as it can be bent starting from the bending portion 13, and if the sheet-like positioning material 1F is a flexible sheet such as a resin sheet, it may be bent so that the sheet-like positioning material 1F curves starting from the bending portion 13.
[0080] [Modification of the second embodiment] A modified example of the second embodiment will be described in detail. The difference between the modified example of the second embodiment and the second embodiment is that in the second embodiment, the sheet-like positioning material 1E is made up of a guide sheet equipped with an opening guide 10, and the guide sheet also functions as a position guide, but in this embodiment, the sheet-like positioning material 1F is configured to include a tab-shaped member 14, as shown in Figure 26, in addition to the guide sheet 1g equipped with the opening guide 10. Below, the differences between the modified example of the second embodiment and the second embodiment will be described.
[0081] The tab-shaped members 14, 14 are preferably arranged spaced apart from each other along opposing sides of the guide sheet 1g, on both sides of the adhesive portion 12. When the tab-shaped member 14 is folded at the folding portion 13, as shown in FIG. 27, it has a tab 14a that protrudes from one end 15, which serves as the starting point for folding. The tab-shaped member 14 can function as a position guide 11 by indicating the installation position 102 of the fireproofing material to be installed in the partition material 100 between the tabs 14a, 14a. That is, as shown in FIG. 28, the position guide 11 in the sheet-like positioning material 1G is one side formed by the one end 15 and the tab-shaped member 14, and by installing the fireproofing material in accordance with this position, the fireproofing material can be installed in the predetermined installation position 102.
[0082] The tab-shaped member 14 can be made using at least one material selected from the group consisting of resin sheets such as polyolefin resins, vinyl chloride resins, polycarbonate resins, urethane resins, styrene resins, and phenolic resins, rubber sheets such as synthetic rubber, metal sheets such as metal foils and metal plates, and glass fiber composite materials.
[0083] [Other embodiments] The present invention is not limited to the configurations of the first and second embodiments described above, and any improvements and modifications may be made without departing from the technical spirit of the present invention. For example, in the first embodiment, the sheet-like positioning material 1A represents the minimum shape of the fireproofing material to be installed on the partition material 100. However, as shown in Fig. 29, the sheet-like positioning material 1G may have a larger area than the fireproofing material to be installed on the partition material 100 and may include notches 40-42. The notches 40-42 are cutout portions for marking the positions of the corners of fireproofing materials of various sizes to be installed on the partition material 100, and serve as a position guide for the fireproofing material to be installed on the partition material 100 in the sheet-like positioning material 1G. After the sheet-like positioning material 1G is placed in the opening guide 10A so as to include the opening 100, the installation position 102 of the fireproofing material can be indicated by selecting the notches 40-42 corresponding to the size of the fireproofing material to be installed on the partition material 100. It should be noted that three sets of notches 40-42 are provided assuming that there are three sizes of fireproofing material to be positioned, but one set, two sets, or four or more sets may also be provided.
[0084] 30, the sheet-like positioning material 1H may have a larger area than the fireproofing material to be installed on the partition material 100 and may include fastening indicators 50-52. The fastening indicators 50-52 are cutouts that indicate the installation positions of fastening materials 6 that secure fireproofing materials of various sizes to the partition material 100, and serve as a position guide for the fireproofing material to be installed on the partition material 100 on the sheet-like positioning material 1H. After the sheet-like positioning material 1H is placed in the opening guide 10A so as to encompass the opening 100, the installation positions of the fastening materials 6 can be selected according to the size of the fireproofing material to be installed on the partition material 100, thereby indicating the installation positions 102 of the fireproofing material. It should be noted that three sets of fastening indication portions 50-52 are provided, assuming that there are three sizes of fireproofing material to be positioned, but one set, two sets, or four or more sets may also be provided.
[0085] Also, as shown in Figure 31, the sheet-like positioning material 1I may have multiple slits 10d1, 10d2 extending from one side of the outer periphery that constitutes the sheet-like positioning material 1J, and the slits 10d1, 10d2 may form opening guides and may also have notches 40-42. Also, as shown in Figure 32, the sheet-like positioning material 1J may have multiple slits 10d1, 10d2 extending from one side of the outer periphery that constitutes the sheet-like positioning material 1J, and the slits 10d1, 10d2 may form opening guides and may also be provided with fastening instruction portions 50-52. As described above, the sheet-like positioning materials 1A to 1F can be combined with the sheet-like positioning materials 1G and 1H to have the notches 40 to 42 and the fastening instruction portions 50 to 52.
[0086] In addition, in the first embodiment, the sheet-like positioning material 1A is shown as having an opening guide 10A with a hole having a length that exceeds the longest part D of the opening 101, and having a slit 16 extending from the opening guide 10A to the outer edge of the sheet-like member 3, but it can also be in a form without the slit 16.
[0087] The notches 40-42 and fastening instruction portions 50-52 in the sheet-like positioning materials 1G-1J do not have to have through-holes like notches, and may simply be marks drawn at the corresponding locations on the sheet.
[0088] Furthermore, in the second embodiment, the sheet-like positioning material 1E is shown as having an adhesive portion 12, and is temporarily attached by adhering it to the partition portion 100 with the adhesive portion 12, but it may also be configured as having a magnet portion instead of the adhesive portion 12, and being temporarily attached by adhering it to the partition portion 100 with the magnetic force of the magnet portion. The adhesive portion 12 and the magnet portion may be used together. [Explanation of symbols]
