Description

The present invention relates to a partition penetration structure formed in a partition section of a building or the like, a partition penetration material for forming the partition penetration structure, and a construction method for the partition penetration structure.

In buildings such as apartment buildings, office buildings, and schools, partitions such as walls are often provided with compartment penetrations to allow for the passage of long objects such as cables and pipes. Compartment penetrations are required to have a fireproof structure (fireproof construction) to prevent the spread of fire to other compartments in the event of a fire in one compartment. Partitions are generally hollow walls consisting of two walls with a hollow space between them.

One known method for making a compartment penetration fireproof is to fill the gap between the long insert and the penetration hole with an irregular filler, such as fireproof putty or a fireproof pack with fireproof putty packed inside. When using an irregular filler, a tubular member made of fireproof material may also be placed between the inside of the penetration hole in each wall and the insert (see, for example, Patent Documents 1 and 2).

It is also known to form a fire prevention structure by inserting a steel sleeve or a sleeve made of a fire-resistant material into a compartment penetration. In the case of a steel sleeve, for example, a fire prevention structure is known in which a retaining member is attached to the end of the steel sleeve via an adapter member, and a fire prevention material is filled between the retaining member and the elongated member (see, for example, Patent Document 3).
It is also known that when a sleeve made of a fire-resistant material is used, further fire-resistant material is placed inside the sleeve, and a tubular retaining frame for shielding the through hole is attached to the sleeve on the outside of one of the walls (see, for example, Patent Document 4).

Furthermore, there are many products on the market that contain kits of parts for forming fire-resistant structures. By using kit products, workers can form compartment penetration fire-resistant structures without having to prepare many parts themselves.

Japanese Patent No. 6150933 Patent No. 6348320 JP 2016-23683 A Patent No. 6378092

However, as shown in Patent Document 1, when the gap between the inner circumferential surface of the through hole in each wall section and the insert is sealed with fireproof putty, there is a problem that the workability is poor and the performance varies depending on the worker. When the fireproof pack shown in Patent Document 2 is used, the workability is improved, but the volume of the amorphous filler is constant, and depending on the size of the through hole, there is a risk that the gap between the through hole and the insert cannot be sealed properly. Furthermore, when sealing the gap between the through hole and the insert with an amorphous filler, in the case of a hollow wall, work must be done from both sides of the hollow wall to fill the gap between the through hole and the insert in each wall section, which reduces workability.

On the other hand, when using a sleeve, a fireproof structure can be formed by inserting the sleeve into the partition penetration and shielding the sleeve on one side of the outside of the partition, so the workability is relatively good even for hollow walls. However, in conventional fireproof structures using sleeves, a certain number of parts are required to shield the sleeve, so the workability is not high enough, and it is easy to forget to attach parts.
Furthermore, even kit products tend to have a large number of parts, which means that the workability is not sufficient, and it is easy to forget to install parts.

Therefore, the objective of the present invention is to provide a partition penetration structure that can reduce the number of parts and simplify the work, a construction method for the partition penetration structure, and a partition penetration material.

Hereinafter, the pipe shielding structure of the present invention will be described in more detail using embodiments.
[First embodiment]
Fig. 1 is a cross-sectional view showing a compartment penetration structure 10 according to a first embodiment of the present invention. The compartment penetration structure 10 is for providing a fireproof structure for a compartment penetration part 15 formed in a partition part 11 and into which a long insert 21 is inserted. The insert 21 is a cable, a pipe, or the like, and Fig. 1 shows a mode in which both a cable 21A and a pipe 21B are inserted.

The partition 11 is a member that separates the partitions (first partition A and second partition B) on the wall surface of the building, and has a partition penetration part 15 that penetrates from one outer surface 11A side of the partition 11 to the other outer surface 11B side. The partition 11 in this embodiment is a hollow wall, and is composed of two wall materials (partition materials) 12A, 12B arranged with a gap (hollow part 13) between them. Therefore, the partition penetration part 15 is composed of a through hole 13A formed in one wall material 12A, a through hole 13B formed in the other wall material 12B, and a hollow part 13 between them. The outer surface of one wall material 12A constitutes the outer surface 11A of the partition 11, and the outer surface of the other wall material 12B constitutes the outer surface 11B of the partition 11. The through holes 13A, 13B may have a circular, elliptical, or a shape similar thereto so that when an insert member 18 described later is inserted, the outer peripheral surface of the insert member 18 can fit the shape of the inner peripheral surface of the through holes 13A, 13B. Note that the through holes 13A, 13B in the outer surfaces 11A, 11B respectively constitute the openings 13C, 13D of the partition penetration part 15 provided in the partition part 11.
In this specification, the member constituting the compartment penetration portion 15 is sometimes referred to as a compartment penetration body, and in this embodiment, the partition portion 11 (i.e., the wall materials 12A and 12B) is the compartment penetration body. Also, the through hole provided in the compartment penetration body is sometimes referred to as a body through hole, and in this embodiment, the through holes 13A and 13B are the body through holes.

The compartment penetration treatment structure 10 includes an insertion member 18 and a sheet-like covering material 19. The insertion member 18 and the sheet-like covering material 19 are integrally formed to constitute a compartment penetration treatment material 20. That is, the sheet-like covering material 19 is fixed to the insertion member 18, and when the insertion member 18 is inserted into the compartment penetration portion 15 and attached to the partition portion 11, the sheet-like covering material 19 is also attached to the partition portion 11.
The insertion member 18 is sleeve-shaped and is inserted into the compartment penetration portion 15, and is disposed in the compartment penetration portion 15 so that the insert 21 passes through the inside of the sleeve. Here, the sleeve-shaped insertion member 18 is passed through the compartment penetration portion 15 from one through hole 13A to the other through hole 13B.

The sheet-like cover material 19 formed integrally with the insert member 18 is arranged to cover one opening 13C of the compartment penetration part 15 from the outside of the outer surface 11A. The portion of the sheet-like cover material 19 that covers the opening 13C of the compartment penetration part 15 surrounds the insert body 21 and is fixed to the insert body 21 by a string-like member 22 wound from the outside.

Figure 2 shows details of the compartment penetration treatment material 20 before it is inserted into the compartment penetration part 15. As shown in Figure 2, in the compartment penetration treatment material 20, the insert member 18 is sheet-like, and a sheet-like cover material 19 is laminated on one side of the sheet-like insert member 18. As shown in Figure 2, the sheet-like cover material 19 is laminated so as to protrude outward from one end 18A of the sheet-like insert member 18.

The insert member 18 is made of a fire-resistant material. The fire-resistant material is preferably a thermally expandable material that expands when heated. The thermally expandable material prevents the spread of a fire by expanding in the event of a fire. The insert member 18 may be a sheet-like member as shown in FIG. 2, and may be inserted into the compartment penetration portion 15 by putting the ends of the sheet-like member against each other to form a sleeve as shown in FIGS. 1 and 3. The thickness of the sheet-like insert member 18 is not particularly limited, but may be, for example, 0.5 to 10 mm, and preferably 2 to 6 mm. The insert member 18 may be flexible so that it can be deformed into a sleeve shape.
Alternatively, the insertion member 18 may be formed by unrolling a sheet, placing the ends facing each other, and forming a sleeve shape, which is then inserted into the compartment penetration portion 15 .

The thermally expandable member is formed from a thermally expandable resin composition. The thermally expandable resin composition contains a resin component and a thermally expandable material. By forming the thermally expandable member from a thermally expandable resin composition containing a resin component, the insertion member can be easily curved or deformed, and can be formed into a sleeve shape as described above.
Examples of the thermally expandable material include a foaming agent that expands when heated, a thermally expandable layered inorganic material such as vermiculite and thermally expandable graphite, among which thermally expandable graphite is preferred. By using thermally expandable graphite, the material expands appropriately when heated by fire, and the mechanical strength of the expansion residue after expansion is excellent, which makes it easier to improve fire resistance. Note that the thermally expandable material referred to here does not substantially expand due to molding, etc., which will be described later, and the thermally expandable resin composition maintains its thermal expandability in the thermally expandable member.

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 below these lower limits, the thermally expandable material is prevented from accidentally expanding due to heating other than fire. Also, by setting the temperature below the upper limits, the thermally expandable material is more likely to expand reliably due to heating from fire.
The expansion start temperature of the thermally expandable material can be measured by heating a predetermined amount (e.g., 100 mg) of the thermally expandable material at a constant heating rate (e.g., 10°C/min) and measuring the temperature at which the normal force starts. Any measuring device can be used as long as it is capable of controlling the measurement temperature and measuring the normal stress, and for example, a rheometer can be used.
The expansion ratio of the thermally expandable member is preferably 3 times or more, and more preferably 10 times or more. The upper limit of the expansion ratio is not particularly limited, but is, for example, 50 times. The expansion ratio may be calculated by feeding the thermally expandable member into an electric furnace, heating it at 600°C for 30 minutes, measuring the thickness of a test piece, and calculating the expansion ratio by (thickness of test piece after heating)/(thickness of test piece before heating).

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.

Examples of elastomers include rubbers such as 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. In addition, examples of thermoplastic elastomers include olefin-based thermoplastic elastomers (TPO), styrene-based thermoplastic elastomers (TPS), ester-based thermoplastic elastomers, amide-based thermoplastic elastomers, and vinyl chloride-based thermoplastic elastomers.
The resin component of the thermally expandable resin composition may be one type or a combination of two or more types.

The thermally expandable resin composition may contain a plasticizer. The 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), 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 (TOTM) and triisononyl trimellitate (TINTM), phosphate ester plasticizers such as trimethyl phosphate (TMP) and triethyl phosphate (TEP), and process oils such as mineral oil.
The plasticizers may be used alone or in combination.
When the thermally expandable resin composition contains a plasticizer, the content of the plasticizer in the thermally expandable resin composition is, for example, in the range of 0.3 parts by mass or more and 150 parts by mass or less, and preferably in the range of 10 parts by mass or more and 100 parts by mass or less, per 100 parts by mass of the resin component.
When the amount of the plasticizer is equal to or more than these lower limits, good moldability is likely to be achieved, and when the amount is equal to or less than the upper limits, appropriate strength is imparted to the molded article.

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 making it equal to or more than these lower limits, the moldability of the thermally expandable member can be improved. In addition, flexibility is ensured, making it easier to deform into a sleeve shape. In addition, by making it equal to or less than the upper limit, it becomes possible to blend sufficient amounts of components such as thermally expandable graphite and inorganic fillers.
In addition, 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.

Thermally expandable graphite is a conventionally known substance, and is produced by treating powders of natural flake graphite, pyrolytic graphite, kish graphite, etc. with inorganic acids such as concentrated sulfuric acid, nitric acid, selenic acid, etc., and strong oxidizing agents such as concentrated nitric acid, perchloric acid, perchlorates, permanganates, dichromates, hydrogen peroxide, etc. 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 treating with an acid and then neutralizing the same 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.

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 above the lower limit, the degree of expansion of the graphite tends to increase, resulting in good foaming properties. Also, by keeping the particle size below the upper limit, the dispersibility when kneaded with the resin is good, improving moldability.

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. From these viewpoints, the content of thermally expandable graphite is preferably in the range of 10 parts by mass or more and 200 parts by mass or less, and more preferably in the range of 15 parts by mass or more and 100 parts by mass or less.

The thermally expandable resin composition may further contain an inorganic filler. There is no particular limitation on the inorganic filler, so long as it is an inorganic filler that is generally used in thermally expandable resin compositions. Specific examples of the inorganic filler 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, myca, 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, dehydrated sludge, etc. One or more types of inorganic fillers can be used.
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, relative to 100 parts by mass of the resin component.

Additional additives that are commonly used in thermally expandable resin compositions, such as heat stabilizers, lubricants, processing aids, antioxidants, antistatic agents, pigments, crosslinking agents, and crosslinking accelerators, may be added to the thermally expandable resin composition used in the present invention, as necessary, to the extent that the physical properties of the composition are not impaired. Of these, it is preferable to use processing aids.

The thermally expandable member can be manufactured, for example, as follows. First, a predetermined amount of resin component, thermally expandable material, and other additives that are blended as 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, may be applied to a sheet-like covering material and then appropriately dried, cured, or the like, to form a sheet-like covering material on one side thereof. Alternatively, the sheet-like covering material may be formed on one side thereof by a known method such as extrusion molding. Furthermore, a thermally expandable member previously formed into a sheet may be laminated on the sheet-like covering material by press molding or the like.

The fireproof material may also be a putty-like mixture, which is a resin composition containing at least one inorganic material selected from hydroxides such as aluminum hydroxide and magnesium hydroxide, carbonates such as calcium carbonate and magnesium carbonate, oxides such as magnesium oxide, phosphorus and phosphorus compounds, etc. In this case, the resin component contained in the resin composition may be appropriately selected from the resin components described above. The putty-like mixture may be laminated in a sheet form (i.e., in a layer form) on one side of the sheet-like cover material 19, for example.

The sheet-like covering material 19 is preferably made of a non-combustible material. The sheet-like covering material 19 is made of a material that can be bent or curved so as to cover the opening 13C of the compartment penetration part 15 as described later. The non-combustible material is defined in the Building Standards Act and the Building Standards Act Enforcement Order. Specific examples of the sheet-like covering material 19 include metal foil such as aluminum foil, glass cloth, and a composite of metal foil and glass cloth such as aluminum glass cloth. Among these, aluminum glass cloth is preferred from the viewpoint of fire resistance.
The thickness of the sheet-like cover material 19 is, for example, 0.01 to 1 mm, and preferably 0.05 to 0.5 mm.

Next, the present embodiment will be described in more detail while explaining the construction method of the compartment penetration processing structure with reference to FIG. 3. As shown in FIG. 3(A), the compartment penetration processing material 20 is attached to the compartment penetration part 15 by inserting the sheet-shaped insert member 18 into the compartment penetration part 15 while passing the insert body 21 inside the insert member 18. The insert member 18 is made into a sleeve shape so as to fit the shape of the inner peripheral surface of the through holes 13A, 13B (see FIG. 1) constituting the compartment penetration part 15. That is, the insert member 18 may be made into a sleeve shape so that its outer peripheral surface conforms to the shape of the inner peripheral surface of the through holes 13A, 13B. Since the shape of the inner peripheral surface of the through holes 13A, 13B is generally a circle, an ellipse, or a shape similar thereto, the insert member 28 may be made into a sleeve shape by rolling it, and may be made into a circle, an ellipse, or a shape similar thereto.
When the tape is formed into a sleeve shape, the ends are placed facing each other, and at this time, the ends may be bonded together with an adhesive, a pressure-sensitive adhesive, an adhesive tape, or the like. Here, the adhesive, the pressure-sensitive adhesive, and the adhesive tape are preferably made of a non-combustible material, a semi-non-combustible material, or a flame-retardant material, and a flame retardant may be blended into the adhesive, the pressure-sensitive adhesive, etc. The adhesive tape includes a substrate and an adhesive layer provided on one side of the substrate, and each of the substrate and the adhesive layer is preferably made of a non-combustible material, a semi-non-combustible material, or a flame-retardant material.
However, the insertion member is not limited to having its ends facing each other, and may be in the form of a sleeve with its ends overlapping each other.

The sheet-like cover material 19 that is laminated to the insert member 18 is formed into a cylindrical shape to match the shape of the insert member 18, with the sheet-like cover material 19 being disposed on the outside of the insert member 18. Therefore, it is preferable that the insert member 18 be formed into a cylindrical shape so as to match the shape of the inner circumferential surfaces of the through holes 13A and 13B via the sheet-like cover material 19.

As shown in FIG. 3(A), the lateral ends of the insert member 18 face each other so that the end 18A from which the sheet-like cover material 19 protrudes is one end of the sleeve in the axial direction. The lateral direction is a direction perpendicular to the axial direction. The insert member 18 is inserted into the partition-penetrating portion 15 with the end opposite the end 18A (other end 18B) as the leading end and the end 18A as the rear end. As a result, the portion of the sheet-like cover material 19 protruding from the end 18A extends outward from one opening 13C of the partition-penetrating portion 15 as shown in FIG. 3(B). That is, the sheet-like cover material 19 protrudes outward not only from the end of the insert member 18 but also from the partition-penetrating body (i.e., the partition portion).

After the compartment penetration treatment material 20 is inserted into the compartment penetration portion 15, the sheet-like covering material 19 extending outward from the through hole 13A is appropriately bent or folded to reduce its diameter as shown in FIG. 3(C), so that the sheet-like covering material 19 closely surrounds the outer periphery of the insert 21. Then, a string-like member 22 is wound around the surrounding portion of the sheet-like covering material 19, and the sheet-like covering material 19 is fixed to the insert 21 by the string-like member 22, so that one opening 13C of the compartment penetration portion 15 is covered by the sheet-like covering material 19.

The string-like member 22 may be any bendable member, and is preferably a wire member that includes 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, such as a wire mould. When a wire member is used, the sheet-like sealing material 19 can be fixed to the insert 21 simply by twisting or twisting.

The compartment penetration structure 10 having the structure described above prevents communication between the hollow portion 13 and the outside of the partition portion 11 by the insert member 18, and also prevents communication between one opening 13C of the compartment penetration portion 15 and the other opening 13D, because one opening 13C of the compartment penetration portion 15 is covered by the sheet-like cover material 19. Therefore, the compartment penetration structure 10 can form an appropriate fireproof structure for the compartment penetration portion 15.

Furthermore, the compartment penetration structure 10 of this embodiment can be constructed by inserting the compartment penetration treatment material 20 into the compartment penetration part 15 from one opening 13C and then covering one opening 13C with the sheet-like cover material 19 provided on the compartment penetration treatment material 20. Therefore, the compartment penetration structure can be formed with a small number of parts, and all work can be performed from one side (the outer surface 11A side) of the partition part 11, improving workability.
In this embodiment, the sheet-like insertion member 18 may be formed into a sleeve shape at the construction site and inserted into the compartment penetration portion 15. Therefore, the size of the sleeve-like insertion member 18 can be adjusted by cutting the sheet-like insertion member 18, for example, to match the size of the through holes 13A and 13B, so that it can be used with compartment penetration portions 15 of various sizes.
Furthermore, the insertion member 18 of the present embodiment is made of a fire-resistant material having a relatively high degree of flexibility as described above. Therefore, when the insertion member 18 is inserted into the compartment penetration portion 15, the cables constituting the insertion body 21 are prevented from being damaged by the insertion member 18.
In addition, in this embodiment, a fireproof structure can be formed without placing anything other than the insert body 21 inside the body through hole (through holes 13A, 13B) on the insert body 21 side of the insertion member 18.

Second Embodiment
Next, a second embodiment of the present invention will be described with reference to FIG. 4. The second embodiment differs from the first embodiment in the structure of the partition-penetrating treatment material. The second embodiment will be described below with respect to the differences from the first embodiment. In addition, in the following description of different embodiments, the same reference numerals will be used to designate members having the same configuration.

The compartment penetration treatment material 25 in the second embodiment further comprises an adhesive layer 24 in addition to the insert member 18 and the sheet-like cover material 19. The adhesive layer 24 is a member for adhering and fixing the compartment penetration treatment material 25 to the partition portion 11 (see FIG. 1). In the compartment penetration treatment material 25 of this embodiment, the adhesive layer 24 is laminated on the surface of the sheet-like cover material 19 opposite to the surface on which the insert member 18 is provided. The configurations of the insert member 18 and the sheet-like cover material 19 in this embodiment are the same as those in the first embodiment.

The adhesive layer 24 may be, for example, a single adhesive layer formed from an adhesive, or may be a double-sided adhesive tape attached to the sheet-like cover material 19. The double-sided adhesive tape has adhesive layers provided on both sides of a base material, and is attached to the sheet-like cover material 19 via one adhesive layer, and the compartment penetration treatment material 25 is adhered to the partition portion 11 by the other adhesive layer.
The adhesive constituting the adhesive layer is not particularly limited, and for example, an acrylic adhesive, a urethane adhesive, a rubber adhesive, a silicone resin adhesive, etc. may be used. A release sheet such as release paper may be further laminated on the adhesive layer 24, and in that case, the release sheet may be peeled off before the adhesive layer 24 is laminated to the partition portion 11. The thickness of the adhesive layer 24 is smaller than the thickness of each of the insertion member 18 and the sheet-like sealing material 19, and is, for example, 5 to 400 μm, preferably 10 to 150 μm.
Here, the adhesive layer 24 is preferably non-flammable, semi-non-flammable, or flame-retardant, and a flame retardant may be blended into the adhesive used. In addition, a non-flammable, semi-non-flammable, or flame-retardant substrate may be used for the substrate of the double-sided adhesive tape.

The partition penetration treatment material 25 may be adhered to the partition 11 via the adhesive layer 24. From the viewpoint of workability, the partition penetration portion 25 is preferably attached to the inner peripheral surface of the through hole 13A (i.e., one opening 13C, see FIG. 1) via the adhesive layer 24. Therefore, the adhesive layer 24 of the partition penetration treatment material 25 may be disposed at a position corresponding to one end 18A or its vicinity. As described above, the construction of the partition penetration treatment structure using the partition penetration treatment material 24 is performed from one outer surface 11A (see FIG. 1) side of the partition 11, so that it is easy to attach the adhesive layer 24 to the inner peripheral surface of one opening 13C, improving workability.

As described above, in this embodiment, the adhesive layer 24 is provided so that the partition-penetrating treatment material 25 can be fixed to the partition portion 11, making it easier to position the partition-penetrating treatment material 25 in the desired position and maintain it in that state.

In each of the above embodiments, the sheet-like covering material 19 is disposed on the outer circumferential side of the insert member 18 inside the compartment penetration portion 15, but the sheet-like covering material 19 may be disposed on the inner circumferential side of the insert member 18. When the sheet-like covering material 19 is disposed on the inner circumferential side, the outer circumferential surface of the insert member 18 comes into direct contact with the inner circumferential surfaces of the through holes 13A, 13B.
Furthermore, when the sheet-like cover material 19 is disposed on the inner periphery side, in the compartment penetration treatment material 25 of the second embodiment, the adhesive layer 24 is laminated on one surface of the insert member 18. Specifically, the adhesive layer 24 may be laminated on the surface of the insert member 18 opposite to the surface on which the sheet-like cover material 19 is provided.

Even when the sheet-like covering material 19 is disposed on the inner periphery side of the insert member 18, as in the first and second embodiments, the insert member 18 prevents communication between the hollow portion 13 and the outside of the partition portion 11, and one opening 13C of the compartment penetration portion 15 is covered by the sheet-like covering material 19. Therefore, communication between one opening 13C of the compartment penetration portion 15 and the other opening 13D is also prevented. Therefore, the compartment penetration processing structure can form an appropriate fireproof structure for the compartment penetration portion 15.
In this case, a fireproof structure can be formed without placing anything other than the sheet-like cover material 19 and the insert body 21 inside the body through hole on the insert member 18's insert body 21 side.

[Third embodiment]
Next, a third embodiment of the present invention will be described with reference to Figures 5 and 6. Figures 5 and 6 respectively show a compartment penetration treatment material 35 and a compartment penetration structure 30 in the third embodiment.
In the third embodiment, as shown in FIG. 5, a plurality of cuts 28B are formed in the insert member 28. Each cut 28B is made from one end 28A of the insert member 28 to the middle of the insert member 28. In addition, when the partition penetration treatment material 35 is inserted into the partition penetration portion 15, as shown in FIG. 6, the sheet-like cover material 29 is disposed inside the insert member 28. Since the insert member 28 has the cuts 28B, as shown in FIG. 6, the one end 28A is folded back outward to form a brim-shaped locking member 28C. The locking member 28C is locked to the outer periphery of the through hole 13A (i.e., one opening 13C) on the outer surface 11A or inside the through hole 13A, and the one end 28A side of the insert member 28 is fixed to the partition portion 11. Therefore, the partition penetration treatment material 35 inserted into the partition penetration portion 15 is reliably fixed to the desired position of the partition penetration portion 15.

[Fourth embodiment]
Next, a fourth embodiment of the present invention will be described. As shown in FIG. 7, the compartment penetration treatment material 45 of the fourth embodiment includes an insert member 38 and a sheet-like cover material 39 having the same configuration as the first embodiment. In addition, a locking member 41 formed separately from the insert member 38 is laminated on the portion of the sheet-like cover material 39 that protrudes from the insert member 38. The locking member 41 is disposed on the surface of the sheet-like cover material 39 on which the insert member 38 is provided, with a gap 42 between the insert member 38 and the locking member 41. The locking member 41 may be sheet-like like the insert member 38, or may be putty-like, and may be made of a fire-resistant material or a foam such as foamed polyethylene, foamed polypropylene, foamed polystyrene, or foamed polyurethane. The insert member 38 and the locking member 41 may both be formed from a thermally expandable resin composition, or a putty-like mixture that is a resin composition containing the inorganic material described above. If the insert member 38 and the locking member 41 are both formed from the same material, such as a thermally expandable resin composition or the putty-like mixture described above, they can be easily formed, for example, by intermittent coating.

The insert member 38 and the locking member 41 are arranged through the gap 42, and as shown in FIG. 8, by folding the sheet-like cover material 39 in the gap 42, a step sheet is formed in which the locking member 41 is connected to one end 38A of the insert member 38 through a step 42A. Therefore, when the partition penetration treatment material 45 (i.e., the insert member 38, the locking member 41, and the sheet-like cover material 39) is inserted into the partition penetration part 15 in a sleeve shape so that the sheet-like cover material 39 is arranged on the inner periphery side of the insert member 38, the locking member 41 located on the outer periphery side of the insert member 38 is connected to one end 38A of the insert member 38, as shown in FIG. 9. Therefore, in the partition penetration treatment structure 40, the partition penetration treatment material 45 inserted in a sleeve shape is locked to the outer periphery or inside of one opening 13C of the partition penetration part 15 by the locking member 41, and is reliably fixed to the desired position of the partition penetration part 15. In the fourth embodiment, the locking member 41 may be provided on a portion of the protruding portion of the sheet-like cover member 39, as shown in FIG. 7, or may be provided on the entirety of the protruding portion.

In the second to fourth embodiments, the partition-penetrating treatment material is fixed to the partition 11 via an adhesive layer or a locking member, but it may be fixed to the partition by means other than an adhesive layer and a locking member. For example, a sleeve-shaped insert member may be fixed to the partition by known means such as a screw or a tacker. The locking member may also be any member that is placed on the outer periphery of the insert member, and is not limited to the configuration of the third and fourth embodiments described above. For example, it may be a sheet-shaped cover material or a block-shaped member attached to the insert member.

[Fifth embodiment]
Next, a fifth embodiment of the present invention will be described with reference to Figures 10 and 11. The fifth embodiment differs from the first embodiment in that a functional member is further provided in the partition penetration processing structure. The fifth embodiment will be described below with respect to the differences from the first embodiment.

FIG. 10 shows the functional member 50 used in the fifth embodiment. The functional member 50 in the fifth embodiment is a member (also called a "covering functional member") that further covers the sheet-like cover material 19 that covers the opening. The functional member 50 is formed of metal, resin material, rubber material, or the like. As shown in FIG. 10, the functional member 50 in this embodiment is divided into two and consists of a pair of divided pieces 50A and 50B, and the divided pieces 50A and 50B are butted together to form the functional member 50. The divided pieces 50A and 50B may be fixed to each other by, for example, providing a convex portion, a concave portion, or the like on each of the butting surfaces of each other and fitting them together.
The functional member 50 is cap-shaped and has a top surface 51 and a side surface 52 erected on the top surface 51. The side surface 52 has a certain height so that the sheet-like cover material 19 can be stored therein. The inner diameter of the functional member 50 (side surface 52) is larger than the diameter of one opening 13C of the compartment penetration part. The top surface 51 is also provided with a hole 51A through which the penetrating body 21 passes.
The hole 51A may be circular, or may be any shape other than circular depending on the shape of the penetrating body 21. The hole 51A may be smaller than the size of the penetrating body 21. Also, a notch may be provided instead of the hole 51A. Even if the size of the hole 51A is smaller than the penetrating body 21, or even if a notch is provided instead of the hole 51A, when the functional member 50 is made of rubber or a resin material, when the penetrating body 21 is inserted into the hole 51A (or the notch), the top surface 51 bends and the penetrating body 21 can be inserted into the hole 51A (or the notch).

After the opening 13C is covered with the sheet-like sealing material 19, the functional member 50 is attached to the outer surface 11A of the partition 11 as shown in Fig. 11. Here, since the functional member 50 is divided into two divided pieces 50A, 50B as described above, it is preferable that the two pieces are butted together so as to sandwich the insert 21 from both sides and attached to the outer surface 11A.
In addition, the functional member 50 may be fixed to the outer surface 11A of the partition portion 11 by known fixing means such as adhesive, glue, screws, or tackers, or the outer surface 11A may have recesses or protrusions, etc., and the functional member 50 may be fixed to the outer surface 11A by fitting or the like.

The sheet-like covering material 19 may be bent or folded, resulting in wrinkles and an unattractive appearance, but by further covering the sheet-like covering material 19 with the functional member 50 as in this embodiment, the appearance of the compartment penetration processing structure 55 is improved. That is, the functional member 50 functions as a decorative material. Furthermore, the functional member 50 is disposed outside the area defined by the sheet-like covering material 19 and the insert member 18, and does not impede the formation of the fire-retardant structure.
However, the functional member 50 is not limited to a function as a decorative material, and can impart various functions to the compartment penetration processing structure 55. For example, the functional member 50 may impart functions such as sound insulation, odor prevention, and vibration control to the compartment penetration processing structure 55. Note that the sound insulation performance and odor prevention performance are functions to prevent sound leakage, odor leakage, and the like from one outer surface 11A (or 11B) side to the other outer surface 11B (or 11A). Also, the vibration control performance is a function to prevent the penetrating body 21 from vibrating.

The functional member 50 exerts a certain degree of sound insulation and deodorization performance by covering the opening 13C, and exerts a certain degree of vibration control performance by supporting the insert 21 by the inner peripheral surface of the hole 51A, but the material of the functional member 50 may be appropriately selected according to the desired function. For example, if it is desired to impart a sound insulation function to the functional member 50, it may be formed from a sound insulation material such as a foam or a rubber material, and if it is desired to impart an odor prevention function, it may be blended with a deodorant or a deodorizer in the resin material or rubber material constituting the functional member 50. Also, if it is desired to impart a vibration control function to the functional member 50, it may be formed from a rubber material or the like. Furthermore, additional members may be attached to the inner surface of the functional member 50 (for example, the inner surface of the top surface 51) or the like according to the function to be imparted, for example, a sound insulation material, a deodorant, a deodorant, or the like may be attached.

As described above, in this embodiment, by providing the functional member 50 to the compartment penetration processing structure 55, it is possible to provide various functions while forming an appropriate fireproof structure for the compartment penetration section 15. Furthermore, even when attaching the functional member 50, an increase in the number of parts can be prevented, and all work can be performed from one side of the partition section 11 (the outer surface 11A side), improving workability.

As described above, the functional member that further covers the sheet-like cover material 19 that covers the opening 13C is not limited to the above configuration, and may have any shape as long as it is a member that can cover the sheet-like cover material. One modified example of such a functional member is shown in FIG. 12. As shown in FIG. 12, in this modified example, the functional member is not divided into two, but is composed of a single functional member 57. The functional member 57 is cap-shaped like the functional member 50 in the fifth embodiment described above, has a top surface 58 and a side surface 59, and a hole 58A is provided in the top surface 58. The functional member 57 also has a slit 57A that extends from the hole 58A toward the outer peripheral surface, and the slit 57A is formed across the top surface 58 and the side surface 59. By having the slit 57A, the functional member 57 can insert the insert 21 into the hole 58A through the slit 57A even if it is not divided into two. In this modified example, a cut may be provided in the top surface 58 instead of the hole 58A.

The functional member that further covers the sheet-like cover material is not limited to the above configuration and may have any other configuration, for example, it may be divided into three or more parts. Also, for example, the functional member is fixed to the partition portion 11 (i.e., the outer surface 11A), but it does not need to be fixed to the partition portion 11, and may be fixed to either the sheet-like cover material or the insert member, for example. In this case, the functional member may be fixed to either the sheet-like cover material or the insert member from the outer periphery side by known fixing means such as adhesive, pressure sensitive adhesive, screws, tackers, etc., or may be fixed by fitting into these.

Sixth embodiment
Next, a sixth embodiment of the present invention will be described with reference to Figures 13 and 14. In the fifth embodiment, the functional member is arranged to cover the sheet-like cover member, but in this embodiment, the functional member is a functional member (also called an "internal functional member") arranged inside the compartment penetration processing structure covered by the sheet-like cover member. The sixth embodiment will be described below with respect to the differences from the fifth embodiment.

The functional member 60 in this embodiment is provided on and supported by a sheet-like cover material 69. Specifically, in the compartment penetration treatment material 65, the functional member 60 is laminated on a portion of the sheet-like cover material 69 that protrudes from one end 68A of the insertion member 68. The configurations of the sheet-like cover material 69 and the insertion member 68 are similar to those of the first embodiment.
The functional member 60 may have functions such as sound insulation, deodorization, and vibration damping, and may be a sound insulation material such as a foam or a rubber material, a deodorant or a deodorant itself, or a resin material or a rubber material containing a deodorant or a deodorant. It may also be a rubber material that functions as a vibration damping material. In addition, the functional member 60 is shown in FIG. 13 as being formed in a sheet shape, but as described later, the functional member 60 may have any shape as long as it does not prevent the sheet-like cover material 69 from covering the opening 13C.

In this embodiment, when the compartment penetration treatment material 65 (i.e., the insert member 68 and the sheet-like cover material 69) is formed into a sleeve shape and inserted into the compartment penetration part 15, the portion of the sheet-like cover material 69 protruding from one end 68A of the insert member 68 and the functional member 60 laminated on the protruding portion are positioned outside the outer surface 11A. Note that the functional member 60 is positioned inside the sheet-like cover material 69, and is therefore not shown in FIG.
The protruding portion of the sheet-like covering material 69 can be reduced in diameter in the same manner as in the above-described embodiments, so that the sheet-like covering material 69 can be closely surrounded by the outer periphery of the insert 21. At this time, the sheet-like covering material 69 may be closely surrounded by the insert 21 via the functional member 60 disposed inside. Then, the string-like member 22 is wound around the surrounding portion of the sheet-like covering material 69, and the sheet-like covering material 69 is fixed to the insert 21 by the string-like member 22, so that one opening 13C of the compartment penetration portion 15 is covered by the sheet-like covering material 69.

As described above, in the sixth embodiment, the functional member 60 is also provided on the partition penetration treatment material 65, so that the function can be imparted with a small number of parts and with good workability. In addition, the functional member 60 does not prevent the sheet-like cover material 69 from covering the opening 13C, so it does not hinder the formation of a fire-resistant structure.

In the sixth embodiment described above, the internal functional member was positioned inside the sheet-like cover material, but it may be positioned anywhere within the section-penetrating processing structure partitioned by the insert member and the sheet-like cover material, for example, it may be positioned inside the insert member.
Furthermore, the configuration of the internal functional member may be in any form, and may be placed inside the penetration treatment structure separately from the partition penetration treatment material, for example, may be placed inside the insert member in the form of putty, or putty stored in a bag may be placed inside the insert member.
Furthermore, the internal functional member may be a cap-like member that has a top surface and sides and covers the opening formed by one end 18A of the insert member 18 (see Figure 11) inside the sheet-like cover material, like the covering functional member shown in the fifth embodiment, or it may be a plate-like member that covers the opening formed by one end 18A of the insert member 18.

In the above first to sixth embodiments, the insertion member is formed into a sleeve shape by facing the ends of the sheet-like member, but it may be formed into a sleeve shape in advance. By forming it into a sleeve shape in advance, workability at the site is further improved. In addition, if it is formed into a sleeve shape in advance, the diameter of the insertion member cannot be adjusted when inserting it into the partition penetration part, so it is effective when used for a partition penetration part having a through hole of a predetermined size.

[Seventh embodiment]
An example in which the insert member is formed into a sleeve shape in advance is shown in FIG. 15 as the seventh embodiment. As shown in FIG. 15(A), the compartment penetration treatment material 70 according to this embodiment includes a sleeve-shaped insert member 73 and a sheet-like cover material 74 attached to one end 73A in the axial direction of the insert member 73. The insert member 73 is formed of a fireproof material as described above, and may be formed by any method as long as it is formed into a sleeve shape. In addition, the insert member 73 of the sleeve material may be provided with a slit extending in the axial direction, and the sheet-like cover material may also be provided with a slit. By providing the slit, it becomes easier to pass the insert 21 through the inside of the insert member 73.
The sheet-like covering material 74 is made of a noncombustible material and extends radially outward from one end 73 A in a sheet-like shape. The sheet-like covering material 74 may or may not be laminated on the outer circumferential surface of the sleeve-like insert member 73.

In the present embodiment, as in the above embodiments, the compartment penetration treatment material 70 is formed by inserting a sleeve-shaped insert member 73 into the compartment penetration portion 15 as shown in FIG. 15(B). Thereafter, the sheet-like cover material 74 is bundled and tightly surrounds the outer periphery of the insert body 21 from the outside of the insert body 21 as shown in FIG. 15(C), and then the sheet-like cover material 74 is fixed to the insert body 21 by the string-like member 22 to form the compartment penetration treatment structure 75.

Of course, a functional member may also be provided in the seventh embodiment. The functional member may be a covering functional member that further covers the sheet-like cover material 74, as described in the fifth embodiment and its modified examples, or an internal functional member provided inside the compartment penetration processing structure, as described in the sixth embodiment. Details of the covering functional member and the internal functional member are as described above, but a specific example in which an internal functional member is provided in the compartment penetration structure is shown in Figure 16 as the eighth embodiment.

Eighth embodiment
The internal functional member used in the eighth embodiment may be a cap-shaped functional member 80 as shown in FIG. 16B. The cap-shaped functional member 80 may have a top surface 81 and a side surface 82, as in the fifth embodiment. Furthermore, a notch or a hole may be provided in the top surface 81, and a slit may be provided from the hole (or the notch) toward the outer peripheral surface. Furthermore, the functional member 80 may be divided into two or more parts. However, since the functional member 80 does not need to store a seat cover material inside, the side surface 82 of the functional member 80 does not need to have a certain height, and the functional member may be a plate-shaped member with the side surface 82 omitted.

When a functional member 80 is used as the internal functional member, the insert member 73 is inserted into the partition penetration portion 15 as shown in Fig. 16(A). At this time, the sheet-like cover material 74 is preferably arranged along the outer surface 11A of the partition portion 11. Then, as shown in Fig. 16(B), the functional member 80 is preferably placed on the sheet-like cover material 74 arranged in this manner so as to cover the opening 13C, so that the lower end portion of the functional member 80 (i.e., the lower end portion of the side surface 82) is arranged on the outer periphery of the opening 13C via the sheet-like cover material 74.
The functional member 80 may be fixed to the outer surface 11A of the partition 11 by known fixing means such as screws or a tacker via the sheet-like cover material 74. The cap-like functional member 80 may be fixed by fitting it to the end of the insert member 73 via the sheet-like cover material 74, or may be fixed to the partition 11 or the insert member 73 by any other fixing means.
After the functional member 80 is fixed, the sheet-like cover material 74 is closely wrapped around the outer periphery of the insert 21 from the outside of the insert 21 as shown in Figure 16 (C), and then the sheet-like cover material 74 is fixed to the insert 21 by a string-like member 22 to form a compartment penetration processing structure 85.

In the above description, the present invention has been described in detail by showing embodiments, but the present invention is not limited to the configurations of the above embodiments, and various improvements or modifications may be made without departing from the technical concept of the present invention, and each configuration may be appropriately combined.
For example, in each of the above embodiments, the sheet-like covering material is fixed to the insert by a string-like member, but it may be fixed by something other than a string-like member, for example, it may be fixed to the sheet-like covering material by an adhesive layer or a fire-resistant material. The adhesive layer or fire-resistant material may be laminated in advance on the inside of the sheet-like covering material in a portion that contacts the insert. The adhesive layer may be a single adhesive layer, or it may be a double-sided adhesive tape having a substrate and an adhesive layer provided on both sides of the substrate. In addition, the fire-resistant material may be formed by the above-mentioned thermally expandable resin composition, for example, by applying an uncured or solvent-diluted thermally expandable resin composition to the sheet-like covering material, curing and drying the uncured or undried thermally expandable resin composition in a state of contacting the insert, and fixing the sheet-like covering material and the insert via the fire-resistant material. It may also be fixed by a putty-like mixture that is a resin composition containing at least one inorganic material selected from hydroxides such as aluminum hydroxide and magnesium hydroxide, carbonates such as calcium carbonate and magnesium carbonate, oxides such as magnesium oxide, phosphorus and phosphorus compounds, etc.
The sheet-like cover material may also be fixed by an adhesive tape wound around it from the outside. The adhesive tape may be a single-sided adhesive tape having a substrate and an adhesive layer on one side of the substrate. The details of the substrate and the adhesive layer are as described above.

In each of the above embodiments, the insert member of the present invention is made of a fireproof material, but the insert member may be made of a non-combustible material. Specific examples include mortar, metal tubes such as steel sleeves, inorganic fibers and molded bodies thereof, etc. However, from the viewpoint of preventing damage to the insert body 21, etc., it is preferable that the end of the insert member is made of a soft material with no exposed sharp parts, such as an organic foam, a rubber-like molded body, or a fireproof material.
The insert member itself does not need to be made of a non-combustible material or a fire-resistant material, but may be a pipe or the like having a non-combustible material disposed on at least a portion of its inside or outside. The pipe may be made of a resin material or the like.

In each of the above embodiments, the sleeve-shaped insert member may be partially bent, and the bent portion may cover one opening of the compartment-penetrating portion. In this case, the sleeve-shaped insert member may be bent, for example, at one end in the axial direction. The one opening of the compartment-penetrating portion may be covered by a sheet-like covering material so as to further cover the bent end of the insert member. In this way, the one opening of the compartment-penetrating portion is covered by the end of the insert member and the sheet-like covering material, which makes it easier to improve fire resistance.
One end of the sleeve-shaped insertion member may be bent after being inserted into the compartment through-hole, but may also have a bent shape in advance.

Furthermore, in each of the above embodiments, a fire-resistant material such as a thermally expandable member may be disposed inside the compartment penetration structure defined by the insert member and the sheet-like cover material (e.g., inside the insert member, etc.). By disposing a fire-resistant material inside the compartment penetration structure, the fire prevention performance is likely to be improved.
In addition, when the insert is made of a non-combustible material, it is preferable that a fire-resistant material made of a thermally expandable material is disposed inside the compartment penetration structure. In this embodiment, the insert itself does not expand when a fire breaks out, but the fire-resistant material disposed inside the compartment penetration structure expands, thereby appropriately preventing the spread of the fire.

The sheet-like cover material does not need to be a non-combustible material, and may be made of a semi-non-combustible material, a flame-retardant material, or other material. Semi-non-combustible materials and flame-retardant materials are specified in the Building Standards Act and the Enforcement Order of the Building Standards Act.
Furthermore, a non-combustible material may be disposed inside the compartment penetration structure (e.g., inside the insertion member) that is partitioned by the insertion member and the sheet-like cover material. By disposing a non-combustible material inside the compartment penetration structure, fire resistance is likely to be improved. Examples of non-combustible materials that may be disposed inside the compartment penetration structure include glass wool and rock wool. Furthermore, when the sheet-like cover material is made of a material other than a non-combustible material, it is preferable to dispose a non-combustible material inside the compartment penetration structure from the viewpoint of fire resistance.

In the first and second embodiments, the sheet-like cover material is cylindrical together with the insertion member, but it does not have to be cylindrical. For example, the sheet-like cover material may be cut so that it spreads radially outward from one end of the insertion member, as in the seventh embodiment. When the sheet-like cover material is arranged so that it spreads radially outward, the opening 13C is easily covered inside the sheet-like cover material by the cap-like functional member 80 or plate-like functional member shown in FIG. 16 as an internal functional member.

In addition, in each of the above embodiments, the sheet-like cover material is laminated on the insert member and integrated with the insert member, but the sheet-like cover material may be integrated with the insert member in any manner as long as it is fixed to the insert member. For example, the sheet-like cover material may be integrated with the insert member by being connected to an end of the insert member, etc.

In the compartment penetration treatment material of each of the above embodiments, a sheet-like cover material may be laminated on both sides of the insert member. In this case, for example, a laminated structure may be formed in which the sheet-like cover material, the insert member, and the sheet-like cover material are provided in this order, and it is preferable that each sheet-like cover material is configured to protrude beyond the end of the insert member. When the sheet-like cover material is provided on both sides, one opening can be covered by two sheet-like cover materials. Also, one sheet-like cover material may cover one opening of the compartment penetration part, and the other sheet-like cover material may cover the other opening of the compartment penetration part.

In addition, in each of the above embodiments, the insert member may be laminated on the substrate. That is, for example, a laminate structure may be formed in which the substrate, the insert member, and the sheet-like cover material are provided in this order. The substrate is not particularly limited, but may be made of a non-combustible material, such as a metal foil, glass cloth, or a composite of metal foil and glass cloth, such as aluminum glass cloth. Of these, aluminum glass cloth is preferred from the viewpoint of fire resistance. The thickness of the substrate is, for example, 0.01 to 1 mm, preferably 0.05 to 0.5 mm. In this case, the substrate may also be formed into a cylindrical shape together with the insert member and the sheet-like cover material and inserted into the compartment penetration portion.

In addition, in the above description, the partition 11 is a hollow wall with a hollow portion 13 inside, but it is not limited to a hollow wall and may be a wall without a hollow portion, for example, made of a single wall material. Furthermore, the partition 11 is not limited to a wall of a building and may be a ceiling or floor of a building. Even if the partition is a ceiling or floor, it may have a structure with a hollow portion between two partition materials, or a structure without a hollow portion, for example, made of a single partition material.

In addition, in each of the above embodiments, the sheet-like covering material covers one of the openings of the compartment penetration part, but it may cover both openings. In this case, the sheet-like covering material may have any shape, for example, it may be formed so as to protrude outward from both axial ends of the insertion member, and the protruding portions may cover both openings. Also, two sheet-like covering materials may be provided, and each sheet-like covering material may cover both openings.
