Description

The present invention relates to a compartment penetration treatment structure formed in a partition of a building, a compartment penetration treatment material for forming the division penetration treatment structure, and a construction method for the division penetration treatment structure.

2. Description of the Related Art In buildings such as housing complexes, office buildings, and schools, partitions such as walls are sometimes provided with compartment penetration parts for passing long objects such as cables and piping. In order to prevent the spread of fire to other compartments when a fire breaks out in one of the compartments, the compartment penetration part is required to have a structure with fire prevention measures (fireproof structure). The partition is generally made up of two walls, each having a hollow space between the walls.

A method for making the compartment penetration part fireproof is, for example, filling the gap between the elongated insertion body and the through hole with an amorphous filler such as fireproof putty or a fireproof pack filled with fireproof putty inside a bag. It has been known. When using an irregularly shaped filler, a cylindrical member made of a fireproof material may also be provided between the inside of the through hole of each wall portion and the insertion body (for example, Patent Document 1, (see 2).

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

Furthermore, many products that are kits of parts for forming fireproof structures have been on the market. By using the kit product, workers can build a fire protection structure that penetrates a compartment without having to prepare many parts themselves.

However, as shown in Patent Document 1, when the space between the inner circumferential surface of the through hole in each wall and the insertion body is closed with fireproof putty, the workability is poor and the performance varies depending on the operator. There's a problem. When the fireproof pack shown in Patent Document 2 is used, workability is improved, but the volume of the amorphous filler remains constant, and depending on the size of the through hole, it is difficult to properly close the space between the through hole and the insertion body. There is a risk that you will not be able to do so. Furthermore, when filling the space between the through hole and the insertion body with an irregularly shaped filler, it is necessary to work from both sides of the hollow wall in order to fill the space between the through hole and the insertion body on each wall. Yes, and work efficiency decreases.

On the other hand, when using a sleeve, a fireproof structure can be formed by inserting the sleeve into the compartment penetration part and shielding the sleeve on the outside of one side of the partition, so it is possible to form a fireproof structure by inserting the sleeve into the partition penetration part and shielding the sleeve on the outside of one side of the partition The workability is also relatively good. However, conventional fire protection structures using sleeves require a certain number of parts or more to shield the sleeves, and work efficiency is not sufficiently high, making it easy to forget to attach parts. .
Furthermore, even if the product is made into a kit, there will still be a large number of parts, and the workability will not be high enough, making it more likely that parts will be forgotten.

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

[First embodiment]
FIG. 1 is a sectional view showing a compartment penetration treatment structure 10 according to a first embodiment of the present invention. The compartment penetration processing structure 10 is for providing a fireproof structure for the compartment penetration part 15 formed in the partition part 11 and into which the elongated insertion body 21 is inserted. The insertion body 21 is cables, piping, etc., and FIG. 1 shows a mode in which both a cable 21A and a piping 21B are inserted therethrough.

The partition part 11 is a member that partitions between sections (first section A and second section B) on the wall surface of the building, and penetrates from one outer surface 11A side of the partition section 11 to the other outer surface 11B side. It has a section penetration part 15. The partition portion 11 in this embodiment is a hollow wall, and is composed of two wall materials (partition materials) 12A and 12B arranged with a gap (hollow portion 13) in between. Therefore, the partition penetrating portion 15 is constituted by a through hole 13A formed in one wall material 12A, a through hole 13B formed in the other wall material 12B, and a hollow portion 13 located between these. The outer surface of one wall material 12A constitutes the outer surface 11A of the partition section 11, and the outer surface of the other wall material 12B constitutes the outer surface 11B of the partition section 11. The through holes 13A, 13B are circular, oval, or shaped so that the outer peripheral surface of the insertion member 18 can match the shape of the inner peripheral surface of the through holes 13A, 13B when the insertion member 18, which will be described later, is inserted. , it is sufficient to have a shape that approximates these. Note that the through holes 13A and 13B on the outer surfaces 11A and 11B constitute openings 13C and 13D of the partition through portion 15 provided in the partition portion 11, respectively.
In addition, in this specification, the member which comprises the division penetration part 15 is sometimes called a division penetration frame|frame, and in this embodiment, the partition part 11 (namely, wall materials 12A, 12B) becomes a division penetration frame. Further, a through hole provided in a partition penetrating frame is sometimes referred to as a frame through hole, and in this embodiment, the through holes 13A and 13B are the frame through holes.

The compartment penetration treatment structure 10 includes an insertion member 18 and a sheet-like cover material 19. The insertion member 18 and the sheet-like cover material 19 are integrally formed to constitute a compartment penetration processing material 20. That is, the sheet-like cover material 19 is in a state fixed to the insertion member 18, and when the insertion member 18 is inserted into the compartment penetration part 15 and attached to the partition part 11, the sheet-like cover material 19 is also attached to the partition part 11. It will be in a state where it is
The insertion member 18 is inserted into the compartment penetration part 15 in the form of a sleeve, and is arranged in the compartment penetration part 15 so that the insertion body 21 is passed through the inside of the sleeve. Here, the sleeve-shaped insertion member 18 is passed through the partition penetrating portion 15 from one through hole 13A to the other through hole 13B.

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

FIG. 2 shows details of the compartment penetration processing material 20 before being inserted into the compartment penetration part 15. As shown in FIG. 2, in the compartment penetration processing material 20, the insertion member 18 is sheet-shaped, and a sheet-shaped cover material 19 is laminated on one surface of the sheet-shaped insertion member 18. As shown in FIG. 2, the sheet-like cover material 19 is stacked so as to protrude outward from one end portion 18A of the sheet-like insertion member 18. As shown in FIG.

Insert member 18 is constructed from a refractory material. The fireproof material is preferably a thermally expandable member that expands upon heating. The thermally expandable member prevents the spread of fire by expanding in the event of a fire. The insertion member 18 is preferably inserted into the section penetrating portion 15 in the form of a sheet, as shown in FIG. 2, in the form of a sleeve, with its ends facing each other as shown in FIGS. 1 and 3. The thickness of the sheet-like insertion member 18 is not particularly limited, but is, for example, 0.5 to 10 mm, preferably 2 to 6 mm. The insertion member 18 is preferably flexible so that it can be deformed into a sleeve shape.
Alternatively, the insertion member 18 may be formed by rolling a sheet into a roll, making it into a sleeve shape with the ends facing each other, and inserting the sheet into the compartment penetrating 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. Since the thermally expandable member is formed from a thermally expandable resin composition containing a resin component, the insertion member can be easily bent and deformed, and can be formed into a sleeve shape as described above.
Examples of the thermally expandable material include foaming agents that foam when heated, thermally expandable layered inorganic materials such as vermiculite, and thermally expandable graphite. Among them, thermally expandable graphite is preferred. By using thermally expandable graphite, it is appropriately expanded by heating in a fire, and the expanded residue after expansion has excellent mechanical strength, making it easy to improve fire resistance. Note that the term "thermally expandable material" as used herein does not substantially expand during molding or the like described below, 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, for example, 150 to 350°C, more preferably 170 to 300°C, and even more preferably 180 to 280°C. By setting it below these lower limits, the thermally expandable material is prevented from erroneously expanding due to heating other than fire. Further, by setting the value to be below the upper limit value, it becomes easier to reliably expand the thermally expandable material by heating due to fire.
In addition, the expansion start temperature of the thermally expandable material is determined by raising the temperature of a predetermined amount (for example, 100 mg) of the thermally expandable material at a constant temperature increase rate (for example, 10°C/min), and the force in the normal direction increases. It can be measured by measuring temperature. The measuring device may be any device that can control the measurement temperature and measure the stress in the normal direction; for example, a rheometer may be used.
The expansion ratio of the thermally expandable member is preferably 3 times or more, and preferably 10 times or more. The upper limit of the expansion magnification is, for example, 50 times, although it is not particularly limited. The expansion ratio is determined by feeding the thermally expandable member into an electric furnace, heating it at 600°C for 30 minutes, measuring the thickness of the test piece, and calculating the following formula: (Thickness of the test piece after heating)/(Thickness of the test piece before heating) It is best to calculate it based on the thickness of the test piece).

Hereinafter, a thermally expandable resin composition in which the thermally expandable material is thermally expandable graphite will be described in detail. 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, polyether ether ketone, and polycarbonate.

Examples of curable resins include epoxy resins, phenolic resins, melamine resins, urea resins, unsaturated polyester resins, alkyd resins, polyurethanes, thermosetting polyimides, and the like.

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, and urethane rubber. , silicone rubber, and fluororubber. Also included are thermoplastic elastomers such as olefin thermoplastic elastomer (TPO), styrene thermoplastic elastomer (TPS), ester thermoplastic elastomer, amide thermoplastic elastomer, and vinyl chloride thermoplastic elastomer.
The number of resin components 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. Plasticizers are 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 ethylhexyl adipate (DOA), diisobutyl adipate (DIBA), dibutyl adipate (DBA), fatty acid ester plasticizers such as adipic acid polyester, epoxidized ester plasticizers such as epoxidized soybean oil, tri-2-ethylhexyl Trimellitic acid ester plasticizers such as trimellitate (TOTM) and triisononyl trimellitate (TINTM), phosphoric acid ester plasticizers such as trimethyl phosphate (TMP) and triethyl phosphate (TEP), process oils such as mineral oil, etc. Can be mentioned.
One kind or two or more kinds of plasticizers can be used.
When the thermally expandable resin composition contains a plasticizer, the content of the plasticizer in the thermally expandable resin composition is, for example, in the range of 0.3 parts by mass or more and 150 parts by mass or less with respect to 100 parts by mass of the resin component. and preferably in a range of 10 parts by mass or more and 100 parts by mass or less.
When the plasticizer content is above these lower limits, moldability tends to be good, and when the plasticizer content is below the upper limit values, appropriate strength is imparted to the molded article.

The total content of the resin component and 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 40% by mass or more and 70% by mass or less, based on the total amount of the resin composition. More preferred. By setting it above 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 setting the amount to be below the upper limit, it becomes possible to blend components such as thermally expandable graphite and inorganic fillers in sufficient amounts.
In addition, the total content of the resin component and plasticizer means the total content of the resin component and plasticizer when both are contained, and the total content of the resin component alone when the plasticizer is not contained. means content.

Thermally expandable graphite is a conventionally known substance, which is made by mixing powders such as natural flaky graphite, pyrolytic graphite, and quiche graphite with inorganic acids such as concentrated sulfuric acid, nitric acid, and selenic acid, and concentrated nitric acid, perchloric acid, and perchloric acid. Graphite intercalation compounds are produced by treatment with strong oxidizing agents such as chlorates, permanganates, dichromates, and hydrogen peroxide. The thermally expandable graphite produced is a crystalline compound that maintains a carbon layered structure.
The thermally expandable graphite used in the present invention may also be obtained by neutralizing thermally expandable graphite obtained by acid treatment with ammonia, aliphatic lower amine, an alkali metal compound, an alkaline earth metal compound, etc. You can also.
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. When the particle size is equal to or greater than the lower limit, the degree of expansion of graphite tends to increase, resulting in good foamability. Further, by setting the amount to be below the upper limit, the dispersibility when kneading with the resin becomes good, and the moldability improves.

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 based on 100 parts by mass of the resin component. When the content of thermally expandable graphite is 3 parts by mass or more, thermal expandability becomes good. Furthermore, when the amount is 300 parts by mass or less, moldability becomes good, and the surface properties, mechanical properties, flexibility, etc. of the sealing member also become 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, 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. The inorganic filler is not particularly limited as long as it is an inorganic filler generally used in thermally expandable resin compositions.

The range is from 150 parts by mass to 150 parts by mass.

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

The thermally expandable member can be manufactured, for example, as follows. First, a predetermined amount of a resin component, a thermally expandable material, and other optional additives are mixed using a mixer such as a kneading roll to obtain a thermally expandable resin composition. The thermally expandable resin composition may be diluted by appropriately adding a solvent.
The thermally expandable resin composition diluted as necessary may be applied to a sheet-like cover material, dried and cured as appropriate, and formed on one surface of the sheet-like cover material. Alternatively, it may be formed on one surface of the sheet-like cover material by a known method such as extrusion molding. Furthermore, a thermally expandable member previously formed into a sheet may be laminated onto the sheet-like cover material by press molding or the like.

The refractory material is at least one inorganic compound 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. It may also be a putty-like mixture that is a resin composition containing the materials. In this case, the resin component contained in the resin composition may be appropriately selected from the resin components listed above. The putty-like mixture may be laminated, for example, in the form of a sheet (that is, in a layer) on one side of the sheet-like cover material 19.

The sheet-like cover material 19 is preferably made of a noncombustible material. The sheet-like cover material 19 is made of a material that can be bent or curved so that it can cover the opening 13C of the partition penetrating portion 15 as described later. In addition, noncombustible materials are those specified in the Building Standards Act and the Building Standards Act Enforcement Order. Specific examples of the sheet-like cover 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 protection.
The thickness of the sheet-like cover material 19 is, for example, 0.01 to 1 mm, 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 treatment structure using FIG. 3. As shown in FIG. 3(A), the compartment penetration treatment material 20 is constructed by inserting the sheet-shaped insertion member 18 into a sleeve shape and inserting it into the compartment penetration portion 15 while passing the insertion member 21 therethrough. It is attached to the penetration part 15. The insertion member 18 is formed into a sleeve shape so as to match the shape of the inner peripheral surface of the through holes 13A and 13B (see FIG. 1) that constitute the compartment penetration portion 15. That is, the insertion member 18 is preferably formed into a sleeve shape so that its outer circumferential surface follows the shape of the inner circumferential surfaces of the through holes 13A and 13B. The shape of the inner circumferential surface of the through holes 13A and 13B is generally a circle, an ellipse, or a shape similar to these, so the insertion member 28 is preferably rolled into a sleeve shape. Alternatively, it is preferable to have a shape similar to these.
Further, when the sleeve is formed, the ends are faced to each other, but in this case, the ends may be bonded together using an adhesive, a pressure-sensitive adhesive, an adhesive tape, or the like. Here, the adhesive, pressure-sensitive adhesive, and pressure-sensitive adhesive tape are preferably made of a nonflammable material, a quasi-nonflammable material, or a flame-retardant material, and a flame retardant or the like may be added to the adhesive, pressure-sensitive adhesive, and the like. The adhesive tape includes a base material and an adhesive layer provided on one side of the base material, and each of the base material and the adhesive layer is made of a noncombustible material, a semi-noncombustible material, or a flame retardant material. It would be good if it were done.
However, the insertion member is not limited to the embodiment in which the ends thereof face each other, but may be in the form of a sleeve so that the ends overlap each other.

Further, the sheet-like cover material 19 laminated on the insertion member 18 is formed into a cylindrical shape in accordance with the shape of the insertion member 18, but in this case, the sheet-like cover material 19 is arranged on the outside of the insertion member 18. Therefore, the insertion member 18 is preferably formed into a cylindrical shape so as to match the shape of the inner peripheral surface of the through holes 13A and 13B via the sheet-like cover material 19.

As shown in FIG. 3(A), the insertion member 18 is arranged at the lateral end of the insertion member 18 such that one end 18A from which the sheet-like cover material 19 protrudes becomes one end in the axial direction of the sleeve. The parts and ends are facing each other. Note that the lateral direction is a direction perpendicular to the axial direction. The insertion member 18 is inserted into the partition penetrating portion 15 with the end opposite to the one end 18A (the other end 18B) being the leading end and the one end 18A being the rear end. As a result, a portion of the sheet-like cover material 19 protruding from one end 18A is extended outward from one opening 13C of the compartment penetration portion 15, as shown in FIG. 3(B). That is, the sheet-like cover material 19 protrudes not only from the end of the insertion member 18 but also from the partition penetrating frame (i.e., the partition portion).

After the compartment penetration treatment material 20 is inserted into the compartment penetration part 15, the sheet-like cover material 19 extending outward from the through hole 13A is bent or folded as appropriate, as shown in FIG. 3(C). As a result, the sheet-like cover material 19 closely surrounds the outer periphery of the insertion body 21. A string member 22 is wound around the surrounding portion of the sheet-like cover material 19, and is fixed to the insertion body 21 by the string member 22, so that one opening 13C of the partition penetrating portion 15 is connected to the sheet. It is covered with a shaped cover material 19.

The string member 22 may be any member that can be bent, and is preferably a wire member including a wire. The wire member may be a metal wire alone, a resin-coated wire such as Nerekko (registered trademark), which is a metal wire coated with resin, or a wire and fiber entwined called a molding. When a wire member is used, the sheet-shaped sealing material 19 can be fixed to the insertion body 21 simply by twisting or twisting.

In the compartment penetration treatment structure 10 having the structure described above, the insertion member 18 prevents the hollow part 13 from communicating with the outside of the partition part 11, and the one opening 13C of the compartment penetration part 15 is shaped like a sheet. Since it is covered with the cover material 19, communication between one opening 13C and the other opening 13D of the partition penetrating portion 15 is also prevented. Therefore, by using the compartment penetration treatment structure 10, an appropriate fire protection structure can be formed in the compartment penetration portion 15.

Further, in the compartment penetration treatment structure 10 of this embodiment, the compartment penetration treatment material 20 is inserted and attached to the division penetration part 15 from one opening 13C, and then the sheet-like cover material 19 provided on the division penetration treatment material 20 is attached. This can be done by covering one opening 13C. Therefore, the partition penetration processing structure can be formed with a small number of parts, and all the work can be done from one side of the partition portion 11 (outer surface 11A side), improving work efficiency.
Further, in this embodiment, the sheet-like insertion member 18 is preferably formed into a sleeve shape and inserted into the compartment penetration portion 15 at the construction site. Therefore, the size of the sleeve-like insertion member 18 can be adjusted according to the size of the through holes 13A and 13B by cutting the sheet-like insertion member 18, so that the compartment penetration portions 15 of various sizes can be adjusted. can correspond to
Furthermore, the insertion member 18 of this embodiment is made of a relatively flexible fireproof material as described above. Therefore, when inserting the insertion member 18 into the partition penetrating 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 inserter 21 inside the frame through-holes (through-holes 13A, 13B) on the inserter 21 side of the insertion member 18.

[Second embodiment]
Next, a second embodiment of the present invention will be described using FIG. 4. The difference between the second embodiment and the first embodiment is the structure of the partition penetration treatment material. Hereinafter, differences between the second embodiment and the first embodiment will be explained. Furthermore, in the following explanations of different embodiments, the same reference numerals are given to members having the same configuration.

The compartment penetration processing material 25 in the second embodiment further includes an adhesive layer 24 in addition to the insertion 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 processing 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 insertion member 18 is provided. The configurations of the insertion 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 a single adhesive layer formed of an adhesive, for example, or may be a double-sided adhesive tape pasted 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 bonded to the sheet-like cover material 19 via one adhesive layer, and the compartment penetration treatment material 25 is bonded to the sheet-like cover material 19 through the other adhesive layer. It is attached to the partition part 11.
The adhesive constituting the adhesive layer is not particularly limited, and for example, acrylic adhesives, urethane adhesives, rubber adhesives, silicone resin adhesives, etc. can be used. Further, a release sheet such as a release paper may be further bonded onto the adhesive layer 24, and in that case, the release sheet may be peeled off before bonding the adhesive layer 24 to the partition portion 11. The thickness of the adhesive layer 24 is smaller than the respective thicknesses 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 nonflammable, semi-nonflammable, or flame retardant, and a flame retardant or the like may be added to the adhesive used. Furthermore, it is preferable to use a nonflammable, semi-nonflammable, or flame-retardant base material for the double-sided adhesive tape.

The partition penetration treatment material 25 may be adhered to the partition portion 11 via the adhesive layer 24. Further, from the viewpoint of workability, it is preferable that the partition penetrating portion 25 is bonded to the inner peripheral surface of the through hole 13A (that is, one opening 13C, see FIG. 1) via the adhesive layer 24. Therefore, in the partition penetration treatment material 25, the adhesive layer 24 may be placed at a position corresponding to one end portion 18A or the vicinity thereof. As described above, the construction of the compartment penetration treatment structure using the compartment penetration treatment material 24 is performed from the one outer surface 11A (see FIG. 1) side of the partition portion 11, so that an adhesive layer is applied to the inner peripheral surface of one opening 13C. It is easy to bond 24 together, and work efficiency is improved.

As described above, in this embodiment, by providing the adhesive layer 24, the compartment penetration treatment material 25 can be fixed to the partition part 11, so that the division penetration treatment material 25 can be placed at a desired position and maintained in that state. It becomes easier.

Note that in each of the above embodiments, the sheet-like cover material 19 is arranged on the outer circumference side of the insertion member 18 inside the compartment penetration part 15, but the sheet-like cover material 19 is arranged on the inner circumference side of the insertion member 18. may be done. Note that when the sheet-like cover material 19 is arranged on the inner peripheral side, the outer peripheral surface of the insertion member 18 directly contacts the inner peripheral surfaces of the through holes 13A and 13B.
Further, when the sheet-like cover material 19 is arranged on the inner peripheral side, the adhesive layer 24 is laminated on one surface of the insertion member 18 in the partition penetration treatment material 25 of the second embodiment. Specifically, the adhesive layer 24 is preferably laminated on the surface of the insertion member 18 opposite to the surface on which the sheet-like cover material 19 is provided.

Even when the sheet-like cover material 19 is arranged on the inner peripheral side of the insertion member 18, the hollow part 13 and the outside of the partition part 11 are communicated with each other by the insertion member 18, as in the first and second embodiments. In addition, one opening 13C of the partition penetrating portion 15 is covered with the sheet-like cover material 19. Therefore, communication between one opening 13C and the other opening 13D of the partition penetrating portion 15 is also prevented. Therefore, by using the compartment penetration treatment structure, an appropriate fire protection structure can be formed in the compartment penetration portion 15.
Further, in this case, a fireproof structure can be formed without placing anything other than the sheet-like cover material 19 and the inserter 21 inside the frame through-hole on the inserter 21 side of the insert member 18.

[Third embodiment]
Next, differences from the first embodiment of the third embodiment of the present invention will be explained using FIGS. 5 and 6. 5 and 6 respectively show a section penetration treatment material 35 and a section 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 insertion member 28. Each cut 28B is made from one end 28A of the insertion member 28 to the middle of the insertion member 28. Further, when the compartment penetration processing material 35 is inserted into the compartment penetration part 15, the sheet-like cover material 29 is arranged inside the insertion member 28, as shown in FIG. Since the insertion member 28 has a notch 28B, as shown in FIG. 6, the one end 28A is folded back to the outside to form a brim-shaped locking member 28C. The locking member 28C is locked to the outer periphery of the through hole 13A (that is, one opening 13C) or the inside of the through hole 13A on the outer surface 11A, and the one end 28A side of the insertion member 28 is fixed to the partition portion 11. Become. Therefore, the compartment penetration processing material 35 inserted into the compartment penetration part 15 is reliably fixed at a desired position of the division penetration part 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 insertion member 38 and a sheet-like cover material 39 having the same configuration as the first embodiment. Furthermore, a locking member 41 formed separately from the insertion member 38 is further laminated on a portion of the sheet-like cover material 39 that protrudes from the insertion member 38 . The locking member 41 is arranged on the surface of the sheet-like cover material 39 on which the insertion member 38 is provided, with a gap 42 interposed between the locking member 41 and the insertion member 38 . The locking member 41 may be in the form of a sheet like the insertion member 38, or may be in the form of putty, and is made of a fireproof material or a foam such as foamed polyethylene, foamed polypropylene, foamed polystyrene, or foamed polyurethane. It would be good if it were done. The insertion 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 above-mentioned inorganic material. If the insertion member 38 and the locking member 41 are both made of the same material, such as a thermally expandable resin composition or the above-mentioned putty-like mixture, they can be easily formed by, for example, intermittent coating.

The insertion member 38 and the locking member 41 are arranged with a gap 42 in between, and as shown in FIG. This becomes a stepped sheet to which the locking member 41 is connected via 42A. Therefore, the compartment penetration treatment material 45 (that is, the insertion member 38, the locking member 41, and the sheet-like cover material 39) is made into a sleeve so that the sheet-like cover material 39 is arranged on the inner circumferential side of the insertion member 38. When inserted into the partition penetrating portion 15, as shown in FIG. 9, a locking member 41 located on the outer peripheral side of the insertion member 38 is connected to one end 38A of the insertion member 38. Therefore, in the compartment penetration treatment structure 40, the compartment penetration treatment material 45 inserted in the form of a sleeve is locked on the outer periphery or inside of one opening 13C of the compartment penetration part 15 by the locking member 41, and 15 desired positions. In the fourth embodiment, the locking member 41 may be provided on a part of the protruding portion of the sheet-like cover member 39, as shown in FIG. 7, or may be provided on the entire sheet-like cover member 39.

In the second to fourth embodiments described above, the compartment penetration treatment material is fixed to the partition part 11 via the adhesive layer or the locking member, but it may not be fixed to the partition part by means other than the adhesive layer and the locking member. You can. For example, the sleeve-shaped insertion member may be fixed to the partition portion using known means such as screws or tackers. Further, the locking member may also be a member disposed on the outer peripheral side of the insertion member, and is not limited to the configurations of the third and fourth embodiments described above. It may also be a block-shaped member.

[Fifth embodiment]
Next, a fifth embodiment of the present invention will be described using FIGS. 10 and 11. The fifth embodiment differs from the first embodiment in that a functional member is further provided in the compartment penetration treatment structure. Hereinafter, differences between the fifth embodiment and the first embodiment will be explained.

FIG. 10 shows a functional member 50 used in the fifth embodiment. The functional member 50 in the fifth embodiment is a member (also referred to as a "covering functional member") that further covers the sheet-like cover material 19 that covers the opening. The functional member 50 is made 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 parts, each consisting 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, etc. on each abutting surface, and fitting these portions together.
The functional member 50 is cap-shaped and has a top surface 51 and a side surface 52 that stands upright from the top surface 51, and the side surface 52 has a certain height so that the sheet-like cover material 19 can be stored inside. have The inner diameter of the functional member 50 (side surface 52) is larger than the diameter of one opening 13C of the partition penetrating portion. Further, the top surface 51 is provided with a hole 51A through which the insertion body 21 is passed.
The hole 51A may be circular, but may have any other shape depending on the shape of the insertion body 21. The hole 51A may be smaller than the size of the insertion body 21. Moreover, a notch may be used instead of the hole 51A. Even if the size of the hole 51A is smaller than the insertion body 21, or even if a notch is provided in place of the hole 51A, if the functional member 50 is made of rubber or resin material, the insertion body 21 will fit the hole 51A ( When inserted into the hole 51A (or notch), the top surface 51 bends and the insertion body 21 can be inserted into the hole 51A (or 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 portion 11, as shown in FIG. Here, the functional member 50 is divided into the two divided pieces 50A and 50B as described above, and is preferably attached to the outer surface 11A by sandwiching the insertion body 21 from both sides and abutting against each other.
Further, the functional member 50 may be fixed to the outer surface 11A of the partition portion 11 using a known fixing means such as an adhesive, an adhesive, a screw, a tacker, etc. The member 50 may be fixed to the outer surface 11A by fitting or the like.

The sheet-like cover material 19 may be bent or folded and wrinkles may be formed, and the appearance may not be good. However, as in this embodiment, the sheet-like cover material 19 is further covered with the functional member 50. This improves the appearance of the partition penetration treatment structure 55. That is, the functional member 50 functions as a decorative material. Moreover, the functional member 50 is arranged outside the area defined by the sheet-like cover material 19 and the insertion member 18, and does not inhibit the formation of the fireproof structure.
However, the functional member 50 is not limited to the function as a decorative material, and can provide various functions to the compartment penetration treatment structure 55. For example, the functional member 50 may provide functions such as sound insulation, deodorization, and vibration damping to the compartment penetration treatment structure 55. Note that the sound insulation performance and deodorization performance are functions that prevent sound leakage, odor leakage, etc. from one outer surface 11A (or 11B) side to the other outer surface 11B (or 11A). Moreover, the vibration damping performance is a function of preventing the insertion body 21 from vibrating.

The functional member 50 exhibits a certain sound insulation performance and deodorizing performance by covering the opening 13C, and also exhibits a certain vibration damping performance by supporting the insertion body 21 by the inner peripheral surface of the hole 51A. The material of the functional member 50 may be appropriately selected depending on the desired function. For example, when it is desired to provide a sound insulation function, the functional member 50 may be formed of a sound insulation material such as a foam or a rubber material, and when it is desired to provide an odor prevention function, the functional member 50 may be formed of a resin material, rubber, etc. It is best to add deodorizers, deodorizers, etc. to the materials. Further, the functional member 50 may be formed of a rubber material or the like if it is desired to provide a vibration damping function. Furthermore, additional members may be attached to the inner surface (for example, the inner surface of the top surface 51) of the functional member 50 depending on the desired function, such as sound insulating material, deodorant, deodorizer, etc. May be attached.

As described above, in this embodiment, by providing the functional member 50 in the compartment penetration processing structure 55, various functions can be provided to the compartment penetration part 15 while forming an appropriate fire protection structure. Furthermore, even when the functional member 50 is attached, an increase in the number of parts can be prevented, and all work can be done from one side of the partition portion 11 (outer surface 11A side), improving work efficiency.

Note that, 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-described configuration, and may have any shape as long as it can cover the sheet-like cover material. good. A modified example of such a functional member is shown in FIG. As shown in FIG. 12, in this modification, the functional member is not divided into two, but is composed of a single functional member 57. Like the functional member 50 in the fifth embodiment described above, the functional member 57 is cap-shaped and has a top surface 58 and side surfaces 59, and a hole 58A is provided in the top surface 58. Further, the functional member 57 has a slit 57A extending from the hole 58A toward the outer peripheral surface, and the slit 57A is formed across the top surface 58 and side surface 59. Since the functional member 57 has the slit 57A, the insertion body 21 can be inserted into the hole 58A through the slit 57A even if it is not divided into two. Note that also in this modification, a notch may be provided in the top surface 58 instead of the hole 58A.

Note that 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, may be divided into three or more pieces. Further, for example, although the functional member was fixed to the partition portion 11 (i.e., the outer surface 11A), it is not necessary to be fixed to the partition portion 11, and for example, the functional member may be fixed to either the sheet-like cover material or the insertion member. You can. In this case, the functional member may be fixed to either the sheet-like cover material or the insertion member from the outer periphery using a known fixing means such as an adhesive, a pressure-sensitive adhesive, a screw, or a tacker, or may be fitted into these. It may be fixed by

[Sixth embodiment]
Next, a sixth embodiment of the present invention will be described using FIGS. 13 and 14. In the fifth embodiment, the functional member was arranged to cover the sheet-like cover member, but in this embodiment, the functional member is a functional member arranged inside the compartment penetration treatment structure covered by the sheet-like cover member. They differ in that they are members (also referred to as "internal functional members"). Hereinafter, differences between the sixth embodiment and the fifth embodiment will be explained.

The functional member 60 in this embodiment is provided on a sheet-like cover material 69 and is supported by the 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 portion 68A of the insertion member 68. The configurations of the sheet-like cover material 69 and the insertion member 68 are the same as in the first embodiment.
The functional member 60 is preferably provided with functions such as sound insulation, deodorization, and vibration damping, and may include sound insulation materials such as foams and rubber materials, deodorants, deodorizers themselves, resin materials containing deodorants, deodorizers, etc. It may also be made of rubber material. Also, a rubber material that functions as a vibration damping material may be used. In addition, the functional member 60 is shown in a sheet-like manner in FIG. 13, but as will be described later, it may have any shape as long as it does not prevent the sheet-like cover material 69 from covering the opening 13C. good.

In this embodiment, when the compartment penetration processing material 65 (that is, the insertion member 68 and the sheet-like cover material 69) is made into a sleeve shape and inserted into the compartment penetration part 15, one end 68A of the insertion member 68 of the sheet-like cover material 69 is inserted into the compartment penetration part 15. The protruding portion and the functional member 60 laminated on the protruding portion are arranged outside the outer surface 11A. Note that the functional member 60 is not shown in FIG. 14 because it is disposed inside the sheet-like cover material 69.
By reducing the diameter of the protruding portion of the sheet-like cover material 69 in the same manner as in each of the above embodiments, the sheet-like cover material 69 can be closely surrounded by the outer periphery of the insertion body 21. At this time, the sheet-like cover material 69 may be brought into close contact with the insertion body 21 via the functional member 60 disposed inside. Then, the sheet-like cover material 69 has a string-like member 22 wrapped around its surrounding portion and is fixed to the insertion body 21 by the string-like member 22, so that one opening 13C of the partition penetrating portion 15 can be opened in a sheet-like manner. It will be covered with a cover material 69.

As described above, in the sixth embodiment, since the functional member 60 is also provided in the section penetration treatment material 65, functions can be provided with a small number of parts and good workability. Moreover, since the functional member 60 does not inhibit the sheet-like cover material 69 from covering the opening 13C, it does not inhibit the formation of the fireproof structure.

In addition, in the sixth embodiment described above, the internal functional member is placed inside the sheet-like cover material, but it may be placed at any position as long as it is inside the section penetration processing structure partitioned by the insertion member and the sheet-like cover material. For example, it may be located inside the insert member.
Further, the internal functional member may have any configuration, and may be arranged inside the penetration treatment structure separately from the compartment penetration treatment material, for example, it may be arranged inside the insertion member in the form of putty. Alternatively, the putty stored in the bag may be placed inside the insertion member.
Further, the internal functional member has a top surface and a side surface like the covering functional member shown in the fifth embodiment, and is located at one end 18A of the insertion member 18 (see FIG. 11) inside the sheet-like cover material. It may be a cap-shaped member that covers the opening formed by the insertion member 18, or it may be a plate-shaped member that covers the opening formed by the one end portion 18A of the insertion member 18.

In the first to sixth embodiments described above, the insertion member is formed into a sleeve shape with the ends of the sheet-like member facing each other, but it may be formed into a sleeve shape in advance. By forming it into a sleeve shape in advance, workability on 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 inserted into a compartment penetration, so it is effective when used for a compartment penetration that has a through hole of a predetermined size. .

[Seventh embodiment]
An example in which the insertion member is previously shaped into a sleeve is shown in FIG. 15 as a seventh embodiment. As shown in FIG. 15(A), the compartment penetration treatment material 70 according to the present embodiment includes a sleeve-shaped insertion member 73 and a sheet-shaped cover material 74 attached to one end 73A of the insertion member 73 in the axial direction. Equipped with The insertion member 73 is made of a fireproof material as described above, and may be formed by any method as long as it is formed into a sleeve shape. Further, the insertion member 73 of the sleeve material may be provided with a notch extending in the axial direction, and the sheet-like cover material may be similarly provided with a notch. By providing the cut, it becomes easier to pass the insertion body 21 through the inside of the insertion member 73.
The sheet-like cover material 74 is a member that is made of a noncombustible material and extends in a sheet-like shape from one end portion 73A toward the outside in the radial direction. The sheet-like cover material 74 may or may not be laminated on the outer peripheral surface of the sleeve-like insertion member 73.

In the compartment penetration processing material 70 in this embodiment, a sleeve-shaped insertion member 73 is inserted into the compartment penetration part 15, as shown in FIG. 15(B), as in the above embodiments. Thereafter, as shown in FIG. 15(C), the sheet-like cover material 74 is bundled to closely surround the outer periphery of the insertion body 21 from the outside of the insertion body 21, and then the sheet-like cover material 74 is tied with a string. It is preferable to fix it to the insertion body 21 using the shaped member 22 to form the compartment penetration processing structure 75.

Of course, functional members may also be provided in the aspect of the seventh embodiment described above. 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 modification, or a covering functional member that further covers the sheet-like cover material 74 as described in the sixth embodiment. It may be an internal functional member provided inside the penetration treatment structure. The details of the covering functional member and the internal functional member are as described above, but a specific example in which the internal functional member is provided in the partition penetrating structure is shown in FIG. 16 as an eighth embodiment.

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

Also when using the functional member 80 as the internal functional member, the insertion member 73 is inserted into the compartment penetration part 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 may be placed over the sheet-like cover material 74 arranged in such a manner so as to cover the opening 13C. (That is, the lower end 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 is preferably fixed to the outer surface 11A of the partition portion 11 via the sheet-like cover material 74 using known fixing means such as screws or tackers. Further, the cap-like functional member 80 may be fixed by fitting to the end of the insertion member 73 via the sheet-like cover material 74, or by any other fixing means to the partition portion 11 or the insertion member 73. It may be fixed to member 73.
After the functional member 80 is fixed, the sheet-like cover material 74 is closely surrounded by the outer periphery of the insertion body 21 from the outside of the insertion body 21, as shown in FIG. 16(C). 74 is preferably fixed to the insertion body 21 by the string-like member 22 to form the compartment penetration processing structure 85.

In the above explanation, the present invention has been explained in detail by showing the embodiments, but the present invention is not limited to the configurations of the above embodiments, and various improvements and changes can be made without departing from the technical idea of the present invention. Alternatively, each configuration may be combined as appropriate.
For example, in each of the above embodiments, the sheet-like cover material is fixed to the insertion body by the string-like member, but it may be fixed by other than the string-like member. For example, the sheet-like cover material may be fixed to The adhesive layer or the fireproof material is preferably laminated in advance on the inner side of the sheet-like cover material and on the portion that contacts the inserter. The adhesive layer may consist of a single adhesive layer, or may be a double-sided adhesive tape having a base material and adhesive layers provided on both sides of the base material. The fireproof material may be formed from the above-mentioned thermally expandable resin composition, but for example, an uncured or solvent-diluted thermally expandable resin composition may be applied to a sheet-like cover material. The thermally expandable resin composition before drying may be cured and dried while in contact with the insert, and the sheet-like cover material and the insert may be fixed via the fireproof material. Further, 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. It may be fixed with a putty-like mixture.
Further, the sheet-like cover material may be fixed with an adhesive tape wrapped from the outside. As the adhesive tape, it is preferable to use a single-sided adhesive tape having a base material and an adhesive layer on one side of the base material. Details of the base material and adhesive layer are as described above.

In each of the embodiments described above, the insertion member of the present invention is made of a fireproof material, but the insertion member may be made of a noncombustible material. Specific examples include mortar, metal pipes such as steel sleeves, inorganic fibers, and molded bodies thereof. However, in order to prevent damage to the insertion member 21, etc., the end of the insertion member is made of a flexible material with no exposed sharp parts, such as organic foam, rubber-like molded material, or fireproof material. It is preferable.
Further, the insertion member itself does not need to be made of a noncombustible material, a fireproof material, or the like, and may be a pipe or the like in which a noncombustible material is disposed at least partially inside or outside. The pipes are preferably formed of a resin material or the like.

In each of the embodiments described above, a part of the sleeve-shaped insertion member may be bent, and the bent portion may cover one opening of the compartment penetration portion. In this case, the sleeve-shaped insertion member may be bent at one end in the axial direction, for example. One opening of the partition penetrating portion is preferably covered with a sheet-like cover material so as to further cover the bent end of the insertion member. Thereby, one opening of the partition penetrating portion is covered by the end of the insertion member and the sheet-like cover material, thereby making it easier to improve fire protection.
Note that one end of the sleeve-shaped insertion member may be bent after being inserted into the compartment penetration portion, or may have a pre-bent shape.
