Description

Technical Field

[0001] The present invention relates to a partition penetration treatment structure formed in a partition part such as a building, a partition penetration treatment material for forming the partition penetration treatment structure, a construction method of the partition penetration treatment structure, and a cover member.

Background Art

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

[0003] As a method of making the partition penetration part a fire prevention structure, for example, a method of filling a gap between a long insertion body and a through hole with a refractory putty or a refractory pack in which a refractory putty is packed inside a bag body is known. When using an amorphous filler, a cylindrical member made of a refractory material may be arranged between the inside of the through hole of each wall part and the insertion body (see, for example, Patent Documents 1 and 2).

Embodiments for Carrying Out the Invention

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

[0011] [First Embodiment] As shown in FIGS. 1 and 2, the partition penetration treatment structure according to the first embodiment of the present invention is a partition penetration treatment structure having a fireproof structure for a partition penetration portion 15 formed in a partition portion 11 of a building and through which a long insertion body 21 is inserted inside. The partition penetration treatment member used in the partition penetration treatment structure according to the first embodiment of the present invention includes a sheet-like member 3 and a cover member 5, and further includes fastening members 6A and 6B.

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

[0013] In this specification, members (in this embodiment, the sheet-like member 3, the cover member 5, etc.) constructed in the partition penetration portion 15 to form the partition penetration treatment structure 10 may be collectively referred to as the partition penetration treatment material. Also, in the following, the configuration of the partition penetration treatment structure on one opening 13C side of the partition portion 13 will be described. However, in this embodiment, the configuration of the partition penetration treatment structure on the other opening 13D side is the same, so the description thereof is omitted.

[0014] The partition penetration processing structure 10 according to the first embodiment includes, as a partition penetration processing material, a sheet-like member 3 and a cover member 5, and the cover member 5 is fixed to the partition penetration processing structure by a retaining material 6. And at least one of the sheet-like member 3 and the cover member 5 has a refractory material as described later.

[0015] 〔Sheet-like member〕 As shown in FIG. 1, the sheet-like member 3 has a slit 30 for inserting an insertion body 21 therein, and at least one of the slits 30 extends to the outer edge of the sheet-like member 3. The slit 30 is formed by a cut. The insertion body 21 can be inserted into the sheet-like member 3 through the slit 30 extending to the outer edge. Note that the slit 30 may be in a form having a hole for inserting the insertion body 21 therein and a slit 30 extending from the hole to the outer edge of the sheet-like member 3. As shown in FIG. 2, the sheet-like member 3 into which the insertion body 21 is inserted by the slit 30 is disposed on the outer surface 11A so as to cover the gap 13E between the opening 13C and the insertion body 21 from the outside of the partition portion 11, whereby the gap 13E between the opening 13C and the insertion body 21 is blocked by the sheet-like member 3. The sheet-like member 3 is disposed so as to be in contact with both the outer surface 11A of the partition portion 11 and the outer periphery of the insertion body 21.

[0016] The sheet-like member 3 may be fixed to the outer surface 11A of the partition portion 11 by an adhesive layer or a refractory material layer provided on the sheet-like member 3, or may be fixed to the outer surface 11A of the partition portion 11 by a fixing member which is a separate member from the sheet-like member 3 such as a tacker or a screw. Of course, the sheet-like member 3 may be fixed to the partition portion 11 by a combination of two or more of these. Also, the sheet-like member 3 may be fixed to the partition portion 11 together with the cover member 5 by a retaining material 6A, or may be fixed to the partition portion 11 by a fixing member and a retaining material 6A.

[0017] The sheet-like member 3 is preferably installed so as to be in contact with the inserted body 21 and the partition portion 11. By installing the sheet-like member 3 so as to be in contact with the inserted body 21 and the partition portion 11, the opening 13C of the partition portion 11 can be blocked, and the fire resistance performance can be improved.

[0018] The sheet-like member 3 has at least one of a refractory material layer and a non-combustible material layer. Similarly, the cover member 5 has at least one of a refractory material layer and a non-combustible material layer. However, either the sheet-like member 3 or the cover member 5 has a refractory material layer (refractory material). Thereby, the partition penetration treatment structure 10 can ensure fire prevention performance. Also, from the viewpoint of ensuring fire prevention performance, it is preferable that at least the sheet-like member 3 has a refractory material layer, and more preferably the sheet-like member 3 has a refractory material layer and the cover member 5 has a non-combustible material layer.

[0019] The refractory material layer used for the sheet-like member 3 is preferably a thermally expandable member that expands upon heating. The thermally expandable member prevents the spread of fire by expanding during a fire. The thermally expandable member is preferably formed of a thermally expandable resin composition as described later. Also, the refractory material layer may have adhesiveness. Note that the thickness of the refractory material layer in the sheet-like member 3 is not particularly limited, but is, for example, 0.1 to 10 mm, preferably 0.5 to 5 mm. By having a thickness below these upper limit values, flexibility is imparted to the sheet-like member 3. Also, by having a thickness above the lower limit value, it becomes easier to ensure fire prevention performance.

[0020] The sheet-like member 3 may be composed of a single layer of a refractory material layer, may be composed of a single layer of a non-combustible material layer, or may have both a refractory material layer and a non-combustible material layer. Also, the sheet-like member 3 may have a layer other than the refractory material layer and the non-combustible material layer, and examples of such a layer include a base material layer, an adhesive layer, and the like.

[0021] The sheet-like member 3 may, for example, have a refractory layer with adhesiveness or an adhesive layer. The refractory layer with adhesiveness and the adhesive layer may form the outermost surface of the sheet-like member 3. With the above configuration, the sheet-like member 3 can be fixed to the partition portion 11 without using a fixing member as a separate member from the sheet-like member 3. Further, by imparting adhesiveness to the refractory layer itself, it is not necessary to provide an adhesive layer, so that the configuration of the sheet-like member 3 can be further simplified. In addition, when the sheet-like member 3 is provided with a refractory layer or an adhesive layer having adhesiveness on its outermost surface, a release sheet may be attached to the outermost surface. The release sheet may be peeled off from the outermost surface during use.

[0022] The non-combustible material layer used for the sheet-like member 3 is composed of a non-combustible material. The non-combustible material is defined in the Building Standards Act and the Enforcement Order of the Building Standards Act. Specific examples of the non-combustible material layer include metal foils such as aluminum foil and copper foil, and metal foil composites such as composites of metal foils and glass cloth such as glass cloth and aluminum glass cloth. Among these, aluminum glass cloth is preferable from the viewpoint of fire resistance. The thickness of the non-combustible material layer is not particularly limited, but is, for example, 0.01 to 1 mm, preferably 0.05 to 0.5 mm. By having a thickness below these upper limit values, flexibility is imparted to the sheet-like member 3. Also, by having a thickness above the lower limit value, it becomes easier to ensure fireproof performance.

[0023] The base material used as the base material layer is other than the above-mentioned non-combustible materials, and examples include paper, cloth, resin film, etc. The thickness of the base material is, for example, 0.01 to 1 mm, preferably 0.05 to 0.5 mm. The adhesive layer is preferably formed by an adhesive, and as the adhesive, for example, acrylic adhesives, urethane adhesives, rubber adhesives, silicone resin adhesives, etc. can be used. The adhesive layer may be non-combustible, semi-non-combustible, or flame-retardant, and a flame retardant or the like may be blended into the adhesive used. The thickness of the adhesive layer is, for example, 5 to 400 μm, preferably 10 to 150 μm.

[0024] The thickness of the sheet-like member 3 is not particularly limited, but for example, it is 0.1 to 10 mm, preferably 0.5 to 5 mm.

[0025] When the sheet-like member 3 has a multilayer structure, it may have a two-layer structure or a three-layer or more structure. Examples of the two-layer structure include those having structures such as a non-combustible material layer / fire-resistant material layer, a non-combustible material layer / adhesive layer, a fire-resistant material layer / adhesive layer, a base material / fire-resistant material layer, and a base material / non-combustible material layer. In addition, as the three-layer structure having an adhesive layer, there are examples such as a non-combustible material layer / fire-resistant material layer / adhesive layer, a base material / fire-resistant material layer / adhesive layer, and a base material / non-combustible material layer / adhesive layer. Also, as the three-layer structure, those without an adhesive layer such as a non-combustible material layer / base material / fire-resistant material layer, a base material / non-combustible material layer / fire-resistant material layer, and a base material / fire-resistant material layer / non-combustible material layer are also included. In addition, as the structure of four layers or more, there are examples such as those in which an adhesive layer is further provided as the outermost layer of the three-layer structure without the above-mentioned adhesive layer. Typically, there are examples such as an adhesive layer / non-combustible material layer / base material / fire-resistant material layer, a non-combustible material layer / base material / fire-resistant material layer / adhesive layer, a base material / non-combustible material layer / fire-resistant material layer / adhesive layer, and a base material / fire-resistant material layer / non-combustible material layer / adhesive layer. In addition, in the above multilayer structure, the non-combustible material layer and the fire-resistant material layer, the non-combustible material layer and the base material, and the fire-resistant material layer and the base material adjacent to each other may be adhered by a known adhesive. Therefore, in each of the above laminated structures, an adhesive layer may be provided between the above layers. Note that in the multilayer structure, the sheet-like member 3 may have the same layer configuration throughout, or may have a partially different structure. For example, an adhesive layer may be provided in a part of the sheet-like member 3, and a part may have a single-layer structure and a part may have a multilayer structure.

[0026] It is preferable that a metal foil composite is laminated on the surface 3A (see FIG. 2) on the side opposite to the surface 3B facing the partition portion 3 of the sheet-like member 3. By laminating the metal foil composite on the surface 3A of the sheet-like member 3, the fire resistance of the sheet-like member 3 can be improved.

[0027] [Cover member] The cover member 5 is installed so as to cover the opening 13C of the partition through portion 15 provided in the partition portion 11. Here, in the present embodiment, as long as the cover member 5 is disposed at a position covering the opening, there may be another member between the cover member 5 and the opening 13C. In the present embodiment, the sheet-like member 3 is disposed between the cover member 5 and the opening 13C, and the opening 13C is covered via the sheet-like member 3. With such a configuration, the cover member 5 in the present embodiment covers the sheet-like member 3 and closes a part of the gap 13E not closed by the sheet-like member 3.

[0028] As shown in FIG. 1, the cover member 5 includes a first cover portion 50 and a plurality of second cover portions 51 (51A to 51E) that are connected to the first cover portion 50 and are separated from each other. The second cover portions 51 are arranged in a row along one side of the first cover portion 50. By including the first cover portion and the second cover portion, the cover member 5 surrounds the inserted body 21 with the first cover portion 50, and makes it easier to dispose the second cover portion 51 on the partition portion 11, so that the cover member 5 can be easily installed to cover the opening 11C.

[0029] Marks (first mark 52, second marks 53A to 53D) indicating the installation positions of the fixing members 6A and 6B are provided on the cover member 5. A mark (first mark 52) indicating the installation position of the fixing member 6B is provided on the first cover portion 50 of the cover member 5. As shown in FIG. 2, after the first cover portion 50 is wound around the inserted body 21 and installed, the first cover portion 50 is fixed to the inserted body 21 by installing the fixing member 6B on the first mark 52. Further, marks (second marks 53A to 53D) indicating the installation positions of the fixing members 6A are provided on the second cover portions 51 of the cover member 5. As shown in FIG. 2, after the second cover portions 51 are installed on the sheet-like member 3, the second cover portions 51 are fixed to the sheet-like member 3 by installing the fixing members 6A from above the second marks 53A to 53D. Note that the marks (second marks 53A to 53D) can also be said to be marks indicating the fixing positions of the insertion body 21 and the partition portion 11 of each of the first cover portion 50 and the second cover portion 51.

[0030] As shown in FIGS. 2 and 3, the second cover portion 51 of the cover member 5 is disposed on the sheet-like member 3 disposed on the outer surface 11A. Then, the second cover portion 51 of the cover member 5 is fastened to the partition portion via the sheet-like member 3 by inserting the fastening member 6A from the outside of the second cover portion 51 into the partition portion 11 of the partition-through portion 15 from the second marks 53A to 53D. As the fastening member 6A for fastening the second cover portion 51, any member can be used as long as it can be inserted from the second marks 53A to 53D provided on the cover member 5 into the partition portion 11 of the partition-through portion 15 to fix and fasten the cover member 5 to the partition-through portion 15. Examples include fixing members such as tackers and screws. In order to improve the fixing strength of the cover member 5, it is preferable to interpose a washer 60 between the cover member 5.

[0031] The first cover portion 50 of the cover member 5 is fastened to the insertion body 21 in a form that surrounds the insertion body 21 in contact therewith and is suppressed and fixed from the outside along the first mark 52 provided on the first cover portion 50 by the fastening member 6B. In the form of being suppressed and fixed from the outside along the first mark 52 by the fastening member 6B, as the fastening member 6B, a member that can be bent can be used, and a wire member including a wire or an adhesive tape is preferable. The wire member may be a single metal wire, a resin-coated wire in which a metal wire such as a twist lock (registered trademark) is coated with resin, or a wire such as a mold in which a wire and a fiber are intertwined. When a wire member is used, the cover member 5 can be fixed to the insertion body 21 simply by twisting or screwing. The adhesive tape can fix the cover member 5 to the insertion body by, for example, winding the first cover portion 50 along the first mark 52 from the outside. The adhesive tape preferably has a base material and an adhesive layer provided on one surface of the base material. As the base material, paper, resin film, cloth, etc. can be used, or the above-mentioned non-combustible materials can also be used. Further, as the adhesive layer, for example, acrylic adhesives, urethane adhesives, rubber adhesives, silicone resin adhesives, etc. can be used. Also, known flame retardants, etc. may be blended in the adhesive. Further, in the form of being suppressed and fixed by the retaining member 6B from the outside along the first mark 52, as the retaining member 6B, fixing members such as tackers and screws installed from the outside of the first mark 52 can be used. As the retaining member 6B for fastening the first cover portion 50 of the cover member 5 to the insertion body 21, in order to improve the fixing strength, it is possible to combine the means shown in the above-mentioned fixing forms. Specifically, the retaining member 6B can adopt a combination of a wire member and an adhesive tape, a combination of a wire member and fixing members such as screws and tackers, etc.

[0032] On the first mark 52, the retaining member 6B is installed as described above, and at least a part of the first mark 52 is covered by the retaining member 6B. Also, on the second marks 53A to 53D, the retaining member 6A is installed, and each of the second marks 53A to 53D is at least partially covered by the retaining member 6A. With such a configuration, each of the first mark 51 and the second marks 53A to 53D becomes at least partially invisible from the outside, and it can be easily confirmed that they are installed as specified.

[0033] The shape and number of the second cover part 51 are not particularly limited. For example, when the installation form of the second cover part 51 on the partition through-hole 15 is a quadrilateral as shown in FIG. 3, as shown in FIGS. 4(a) and (b), the shape of each of the second cover parts 51 is a right isosceles triangle with the angle a formed by two sides of the second cover part 51 being 90°, and the number is preferably 4 or more. The number of the second cover parts 51 of the cover member 5 shown in FIG. 4(a) is 5. The second cover part 51E is arranged so as to overlap below the second cover part 51A, and by arranging them in a double layer, the retention strength is improved, and the function of suppressing the residue from falling is exhibited. It is preferable that there is something arranged so as to overlap below as shown in FIG. 4(a), but it may not be the case as shown in FIG. 4(b). When the installation form of the second cover part 51 on the partition through-hole 15 is a triangle as shown in FIG. 5(a), as shown in FIG. 5(b), the shape of each of the second cover parts 51 is an isosceles triangle with the angle b formed by two sides of the second cover part 51 being less than 90°, and the number is preferably 3 or more. Specifically, when the installation form of the second cover part 51 on the partition through-hole 15 is an equilateral triangle, the angle b formed by two sides of the second cover part 51 may be set to 60°. When the installation form of the second cover part 51 on the partition through-hole 15 is a star-shaped polygon as shown in FIG. 6(a), as shown in FIG. 6(b), the shape of each of the second cover parts 51 is an isosceles triangle with the angle c formed by two sides of the second cover part 51 being less than 90°, and the number is preferably not less than the number of vertices of the star-shaped polygon. Specifically, when the number of vertices of the star-shaped polygon is 5 as shown in FIG. 6(a), the number of the second cover parts 51 is preferably 5 or more.

[0034] In the above, the shape of each second cover part 51 shows a shape in which two sides approach each other like the above-described triangle, but it is not limited to the above shape. For example, the installation form of the second cover part 51 on the partition through-hole 15 may be a shape in which rectangles are arranged radially as shown in FIG. 7(a). In this case, as shown in FIG. 7(b), the shape of each of the second cover parts 51 can be a rectangle. Also in this case, the number of the second cover parts 51 is not particularly limited. In any installation form of the cover member 5, the marks (the first mark 52 and the second marks 53A to 53D) may be folded or bent and deformed according to the shape of the insertion body 21 and the shape of the sheet-like member 3.

[0035] The cover member 5 preferably covers the surface 3A of the sheet-like member 3 opposite to the surface 3B facing the partition portion 11 of the sheet-like member 3, making the surface 3A of the sheet-like member 3 invisible from the outside. By making the surface 3A of the sheet-like member 3 invisible with the cover member 5, the opening 13C for installing the sheet-like member 3 is covered, the design property of the partition through portion 15 can be improved, and the fire resistance of the partition through portion 15 can be enhanced.

[0036] The cover member 5 is preferably installed so as to be in contact with the insertion body 21. By installing the cover member 5 in contact with the insertion body 21, the opening 13C of the partition portion 11 can be blocked, and the fire resistance can be improved.

[0037] The cover member 5 is installed so as to form a gap 40 between the sheet-like member 3 (i.e., the partition portion), between the insertion body 21, or both. The presence of the gap 40 between the sheet-like member 3 and the cover member 5 or between the insertion body 21 and the cover member allows the cover member 5 to be fixed with a margin for the axial movement of the insertion body 21. By fixing the cover member 5 to the insertion body 21 with a margin, even when the insertion body 21 arranged inside the sheet-like member 3 and the cover member 5 is axially moved after the installation of the sheet-like member 3 and the cover member 5, the margin of the cover member 5 buffers the fact that the sheet-like member 3 and the cover member 5 move together with the insertion body 21. By buffering the fact that the sheet-like member 3 and the cover member 5 move together with the insertion body 21, it is possible to suppress the sheet-like member 3 and the cover member 5 from shifting from the partition through portion 15. That is, with such a configuration, the sheet-like member 3 and the cover member 5 can be continuously maintained and arranged at appropriate positions in the partition through portion 15, and the fire resistance of the partition through portion 15 can be maintained. There can be various forms for the configuration in which there is a gap 40 between the sheet-like member 3 and the cover member 5, and the cover member 5 is fixed with a margin with respect to the axial movement of the inserted body 21. For example, a configuration using a material having flexibility and stretchability such that at least a part of the cover member 5 can be bent or curved, and a configuration in which at least a part of the cover member 5 is fixed so as to have slack with respect to the inserted body 21 can be mentioned.

[0038] The cover member 5 may be composed of a single layer of a refractory material layer, may be composed of a single layer of a non-combustible material layer, or may have both a refractory material layer and a non-combustible material layer. However, it is preferable to have a non-combustible material layer, and it is more preferable to be composed of a non-combustible material layer. Also, it may have a layer other than the refractory material layer and the non-combustible material layer, and examples of such a layer include a base material layer, an adhesive layer, etc. Specific examples of the cover member 5 include metal foils such as aluminum foil, glass cloth, and metal foil composites which are composites of metal foils such as aluminum glass cloth and glass cloth. Among these, aluminum glass cloth is preferable from the viewpoint of fire resistance. The thickness of the non-combustible material layer is not particularly limited, but is, for example, 0.01 to 1 mm, preferably 0.05 to 0.5 mm. By having a thickness below these upper limit values for the non-combustible material layer, flexibility is imparted to the cover member 5. Therefore, the cover member 5 can be wound around the outer periphery of the inserted body 21 while being in close contact therewith, even if it has a non-combustible material layer, for example. Also, by having a thickness above the lower limit value, it becomes easier to ensure fireproof performance.

[0039] The refractory material layer used for the cover member 5 is preferably a thermally expandable member that expands upon heating. The thermally expandable member prevents the spread of fire by expanding during a fire. The thermally expandable member is preferably formed from a thermally expandable resin composition as described later. Also, the refractory material layer may have adhesiveness. Incidentally, the thickness of the refractory layer used for the cover member 5 is not particularly limited, but for example, it is 0.1 to 10 mm, preferably 0.5 to 5 mm. By having a thickness below these upper limit values for the refractory layer, flexibility is imparted to the cover member 5. Therefore, even if the cover member 5 has a refractory layer, the cover member 5 can be easily deformed and wound around the outer periphery of the inserted body 21. Also, by having a thickness above the lower limit value, it becomes easier to ensure fireproof performance.

[0040] The cover member 5 may have a refractory layer having adhesiveness or may have an adhesive layer. The refractory layer having adhesiveness and the adhesive layer may form the outermost surface in the cover member 5. In this case, the adhesive layer or the refractory layer may be used together with the retaining materials 6A and 6B to fix the cover member 5 to the inserted body 21 or the sheet-like member 3.

[0041] As described above, the cover member 5 is preferably a sheet that can be deformed to cover the sheet-like member 3. Also, the cover member 5 is preferably thinner than the sheet-like member 3 so as to be flexible and easily deformable. The thickness of the cover member 5 is not particularly limited, but for example, it is 0.01 to 1 mm, preferably 0.05 to 0.5 mm.

[0042] (Thermally expandable resin composition) Hereinafter, the thermally expandable resin composition used for refractories such as the refractory layer will be described in more detail. The thermally expandable resin composition contains a resin component and a thermally expandable material. By forming the thermally expandable member from the thermally expandable resin composition containing the resin component, the bending and deformation of the sheet-like member 3, the cover member 5, and the tape-like member 4 described later become easy. Examples of the thermally expandable material include a foaming agent that foams upon heating, vermiculite, and thermally expandable layered inorganic substances such as expanded graphite. Among them, expanded graphite is preferred. By using expanded graphite, it can be appropriately expanded by the heating of a fire, and the mechanical strength of the expansion residue after expansion is excellent, making it easier to improve the fire resistance. Here, the thermally expandable material does not substantially expand by molding or the like described later, and the thermally expandable resin composition maintains its thermal expandability in the refractory material.

[0043] The expansion start temperature of the thermally expandable material is not particularly limited, but for example, it is preferably 150 to 350°C, more preferably 170 to 300°C, and even more preferably 180 to 280°C. By setting the lower limit value or less, it is possible to prevent the thermally expandable material from expanding erroneously due to heating other than a fire. Also, by setting the upper limit value or less, it becomes easier to surely expand the thermally expandable material by the heating of a fire. In addition, the expansion start temperature of the thermally expandable material can be measured by heating a predetermined amount (for example, 100 mg) of the thermally expandable material at a constant heating rate (for example, 10°C / min) and measuring the temperature at which the force in the normal direction rises. As the measuring device, any device that can control the measuring temperature and measure the stress in the normal direction may be used. 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 ratio is not particularly limited, but for example, it is 50 times. The expansion ratio may be calculated by supplying the thermally expandable member to an electric furnace, heating it at 600°C for 30 minutes, measuring the thickness of the test piece, and using (the thickness of the test piece after heating) / (the thickness of the test piece before heating).

[0044] Hereinafter, the thermally expandable resin composition in the case where the thermally expandable material is expanded graphite will be described in detail. Examples of the resin component of the thermally expandable resin composition include a thermoplastic resin, a thermosetting resin, and an elastomer. 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) and polypropylene (PP), polyolefins such as ethylene vinyl acetate (EVA), ethylene-propylene-diene copolymer (EPDM), chloroprene (CR), polyesters such as polyethylene terephthalate and polybutylene terephthalate, polycarbonate, polystyrene (PS), polyphenylene sulfide, acrylonitrile-butadiene-styrene copolymer (ABS), acrylonitrile-styrene-acrylonitrile copolymer (ASA), acrylonitrile / ethylene-propylene-diene / styrene copolymer (AES), etc. Examples of curable resins include epoxy resins, phenol resins, melamine resins, urea resins, unsaturated polyester resins, alkyd resins, polyurethanes, thermosetting polyimides, etc.

[0045] Examples of elastomers include natural rubber, silicone rubber, styrene-butadiene rubber, isoprene rubber, butadiene rubber, chloroprene rubber, acrylonitrile-butadiene rubber, nitrile-butadiene rubber, butyl rubber, ethylene-propylene rubber, ethylene-propylene-diene rubber, urethane rubber, silicone rubber, and fluororubber. Also included are thermoplastic elastomers such as olefin-based thermoplastic elastomers (TPO), styrene-based thermoplastic elastomers (TPS), ester-based thermoplastic elastomers, amide-based thermoplastic elastomers, and vinyl chloride-based thermoplastic elastomers. The resin component of the thermally expandable resin composition may be one type or a combination of two or more types.

[0046] In addition, the thermally expandable resin composition is likely to have adhesiveness by using an elastomer as the resin component. Further, from the viewpoint of facilitating the expression of adhesiveness, it is preferable that the elastomer contains a liquid elastomer. Note that the liquid elastomer is an elastomer that becomes liquid at normal temperature and normal pressure.

[0047] The thermally expandable resin composition may contain a plasticizer. The plasticizer is preferably used when the resin component is a thermoplastic resin such as a polyvinyl chloride resin. Specific examples of the plasticizer include phthalate plasticizers such as di-2-ethylhexyl phthalate (DOP), dibutyl phthalate (DBP), diheptyl phthalate (DHP), diisodecyl phthalate (DIDP), adipic acid esters such as di-2-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, trimellitic acid ester plasticizers such as tri-2-ethylhexyl trimellitate (TOTM), triisononyl trimellitate (TINTM), phosphate ester plasticizers such as trimethyl phosphate (TMP), triethyl phosphate (TEP), and process oils such as mineral oil. One or more 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, preferably in the range of 10 parts by mass or more and 100 parts by mass or less with respect to 100 parts by mass of the resin component. When the plasticizer is at or above these lower limit values, the moldability is likely to be good, and when it is at or below the upper limit value, an appropriate strength is imparted to the molded body.

[0048] The total content of the resin component and the plasticizer is preferably 10% by mass or more and 90% by mass or less, more preferably 25% by mass or more and 80% by mass or less, and even more preferably 40% by mass or more and 70% by mass or less, based on the total amount of the resin composition. By setting the content to be not less than these lower limits, the moldability of the thermally expandable member can be improved. In addition, flexibility is ensured, and bending and deformation become easy. By setting the content to be not more than the upper limit, it becomes possible to blend components such as thermally expandable graphite and inorganic fillers in sufficient amounts. Note that the total content of the resin component and the plasticizer means the total content of these when both the resin component and the plasticizer are contained, and means the content of the resin component alone when the plasticizer is not contained.

[0049] Thermally expandable graphite is a conventionally known substance, which is obtained by treating powders such as natural flaky graphite, pyrolytic graphite, and kish graphite with inorganic acids such as concentrated sulfuric acid, nitric acid, and selenic acid, and strong oxidizing agents such as concentrated nitric acid, perchloric acid, perchlorate, permanganate, dichromate, and hydrogen peroxide to form graphite intercalation compounds. The produced thermally expandable graphite is a crystalline compound that maintains the layered structure of carbon. As the thermally expandable graphite used in the present invention, those obtained by neutralizing the thermally expandable graphite obtained by acid treatment with ammonia, aliphatic lower amines, alkali metal compounds, alkaline earth metal compounds, etc. can also be used. Examples of the aliphatic lower amines include monomethylamine, dimethylamine, trimethylamine, ethylamine, propylamine, butylamine, and the like. Examples of the alkali metal compounds and alkaline earth metal compounds include hydroxides, oxides, carbonates, sulfates, organic acid salts, etc. of potassium, sodium, calcium, barium, magnesium, etc.

[0050] The particle size of the thermally expandable graphite is not particularly limited, but those in the range of 20 to 200 mesh are preferred. When the particle size is not less than the lower limit value, the expansion degree of graphite tends to be large and the foaming property becomes good. In addition, by setting the particle size to be not more than the upper limit value, the dispersibility during kneading with the resin becomes good and the moldability is improved.

[0051] In the thermally expandable resin composition, the content of the thermally expandable graphite is, for example, 3 parts by mass or more and 300 parts by mass or less with respect to 100 parts by mass of the resin component. When the content of the thermally expandable graphite is 3 parts by mass or more, the thermal expansibility becomes good. Further, when it is 300 parts by mass or less, the moldability becomes good, and the surface property, mechanical physical properties, flexibility, etc. of the seal member also become good. From these viewpoints, the content of the 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.

[0052] 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. Specifically, for example, 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, dawsonite, hydrotalcite, calcium sulfate, barium sulfate, gypsum fiber, calcium silicate, talc, clay, mica, montmorillonite, bentonite, activated clay, sepiolite, 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 zirconate titanate, aluminum borate, molybdenum sulfide, silicon carbide, stainless steel fiber, zinc borate, various magnetic powders, slag fiber, fly ash, dehydrated sludge, etc. can be mentioned. One kind or two or more kinds of inorganic fillers can be used. When containing an inorganic filler, 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 with respect to 100 parts by mass of the resin component.

[0053] The thermally expandable resin composition may contain a known tackifier. By containing a tackifier, it becomes easier to impart adhesiveness to the thermally expandable member. In addition, to the thermally expandable resin composition used in the present invention, within a range that does not impair its physical properties, if necessary, additives generally used in thermally expandable resin compositions such as heat stabilizers, lubricants, processing aids, antioxidants, antistatic agents, pigments, crosslinking agents, crosslinking accelerators, etc. may be added. Among these, it is preferable to use a processing aid.

[0054] 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 additives blended as necessary are mixed with 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 is applied to a support such as a base material, a non-combustible material, a release sheet, etc., and is appropriately dried, cured, etc., so that a refractory layer (thermally expandable member) is formed on one surface of the support. Further, a refractory layer may be formed on one surface of the support by a known method such as extrusion molding. The refractory layer formed on the release sheet may be peeled from the release sheet to form a sheet-like member or a tape-like member composed of a single layer of the refractory layer. Further, a sheet-like member or a tape-like member having a multilayer structure may be obtained by laminating on another layer after peeling from the release sheet. Further, it may be laminated on another layer while being laminated on the release sheet or another support.

[0055] According to the configuration of the above-described embodiment, the gap 13E between the opening 13C of the partition penetration portion 15 provided in the partition portion 11 and the inserted body 21 is blocked by the sheet-like member 3 and the cover member 5, and at least one of them has a refractory material. Therefore, appropriate fireproof performance can be imparted to the partition penetration portion treatment structure 10. Also, as described above, as shown in FIG. 1, the partition penetration processing structure 10 is first installed so as to block the gap 13E between the opening 13C of the partition penetration portion 15 and the inserted body 21 by the sheet-like member 3. Next, the sheet-like member 3 is covered by the second cover portion 51 of the cover member 5, and the fixing material 6A is inserted into the partition portion 11 of the partition penetration portion 15 from the second marks 53A, 53B, 53C, 53D attached to the second cover portion 51 of the cover member 5, thereby fixing the second cover portion 51 to the partition penetration portion 15. Then, the first cover portion 50 of the cover member 5 is wound around the inserted body 21 and fixed to the inserted body 21 by the fixing material 6B along the first mark 52 attached to the first cover portion 50, so that the construction can be carried out. Therefore, the construction is easy and reliable, and it is possible to visually grasp whether the construction has been carried out reliably. Also, in the present embodiment, since the fireproof structure is formed by the sheet-like member 3 and the cover member 5 without arranging filling materials such as fireproof putty and rock wool inside the partition penetration portion 15, there is no variation among workers.

[0056] Furthermore, in the present embodiment, at least the cover member 5 and the fixing materials 6A and 6B are exposed and visible from the outside. Also, the sheet-like member 3 may be arranged at a position where a part thereof (in the configuration of FIGS. 1 to 3, the side surface of the sheet-like member 3) is visible from the outside. And, inside the partition penetration portion 15, no member other than the inserted body 21 is provided. Therefore, it can be easily inspected by visual observation or photographing whether the partition penetration treatment material has been constructed as specified. Also, it is less likely to occur that the construction is forgotten.

[0057] [Second Embodiment] Next, the second embodiment of the present invention will be described in detail. In the second embodiment, the difference from the first embodiment is that, as shown in FIGS. 8 and 9, the partition penetration treatment material includes a tape-like member 4 and a cover member 5. Hereinafter, the differences between the second embodiment and the first embodiment will be described. Also, the parts for which the description is omitted are the same as those in the first embodiment. Also, in the following description, the members having the same configuration as those in the first embodiment described above are given the same reference numerals. Note that the details of the structure of the cover member 5 itself are the same as those of the first embodiment, and at least one of the tape-shaped member 4 and the cover member 5 has a refractory material.

[0058] 〔Tape-shaped member〕 As shown in FIGS. 8 and 9, the tape-shaped member 4 is wound around the outer periphery of the inserted body 21 for one or more turns. As a result, an end face 4A is formed on the tape-shaped member 4, and the end face 4A can close at least a part of the gap 13E between the opening 13C and the inserted body 21.

[0059] The tape-shaped member 4 has at least one of a non-combustible material layer and a refractory material layer. Similarly, the cover member 5 has at least one of a refractory material layer and a non-combustible material layer. However, at least one of the tape-shaped member 4 and the cover member 5 has a refractory material layer (refractory material). Thereby, the partition penetration processing structure 10 can ensure fireproof performance. From the viewpoint of ensuring fireproof performance, it is preferable that at least the tape-shaped member 4 has a refractory material layer, and more preferably, the tape-shaped member 4 has a refractory material layer and the cover member 5 has a non-combustible material layer.

[0060] The refractory material layer used for the tape-shaped member 4 is preferably a thermally expandable member that expands upon heating. The thermally expandable member prevents the spread of fire by expanding during a fire. The thermally expandable member is preferably formed of the above-described thermally expandable resin composition. Further, the refractory material layer may have adhesiveness. Note that the thickness of the refractory material layer in the tape-shaped member 4 is not particularly limited, but is, for example, 0.1 to 10 mm, preferably 0.5 to 5 mm. By having a thickness below these upper limit values, flexibility is imparted to the tape-shaped member 4. Therefore, for example, even if the tape-shaped member 4 has a refractory material layer, it can be wound around the outer periphery of the inserted body 21 while being in close contact therewith. Also, by having a thickness above the lower limit value, it becomes easier to ensure fireproof performance.

[0061] The tape-shaped member 4 may be composed of a single layer of refractory material, a single layer of non-combustible material, or both a refractory material layer and a non-combustible material layer. Further, it may have layers other than the refractory material layer and the non-combustible material layer, and examples of such layers include a base material, an adhesive layer, and the like.

[0062] The tape-shaped member 4 may have a refractory material layer having adhesiveness or an adhesive layer. The refractory material layer having adhesiveness and the adhesive layer may form the outermost surface of the tape-shaped member 4. With the above configuration, the tape-shaped member 4 can be fixed to the insertion body 21 without using a fixing member as a separate member from the tape-shaped member 4. Further, by imparting adhesiveness to the refractory material layer itself, it is not necessary to provide an adhesive layer, so the configuration of the tape-shaped member 4 can be further simplified. In addition, when the tape-shaped member 4 is provided with a refractory material layer having adhesiveness or an adhesive layer on its outermost surface, a release sheet may be attached to the outermost surface. The release sheet may be peeled off from the outermost surface during use.

[0063] The non-combustible material layer used for the tape-shaped member 4 is composed of a non-combustible material. The non-combustible material is defined in the Building Standards Act and the Enforcement Order of the Building Standards Act. Specific examples of the non-combustible material layer include metal foils such as aluminum foil and copper foil, and metal foil composites such as composites of metal foils and glass cloth such as glass cloth and aluminum glass cloth. Among these, aluminum glass cloth is preferable from the viewpoint of fire resistance. The thickness of the non-combustible material layer is not particularly limited, but is, for example, 0.01 to 1 mm, preferably 0.05 to 0.5 mm. By having a thickness below these upper limit values for the non-combustible material layer, flexibility is imparted to the tape-shaped member 4. Therefore, the tape-shaped member 4 can be wound around the outer periphery of the insertion body 21 while being in close contact therewith, even if it has, for example, a non-combustible material layer. Further, by having a thickness above the lower limit value, it becomes easier to ensure fireproof performance.

[0064] The base material used as the base material layer is other than the non-combustible materials described above, and examples include paper, cloth, resin film, etc. The thickness of the base material is, for example, 0.01 to 1 mm, preferably 0.05 to 0.5 mm. The adhesive layer is preferably formed of an adhesive. As the adhesive, for example, acrylic adhesives, urethane adhesives, rubber adhesives, silicone resin adhesives, etc. can be used. The adhesive layer may be non-combustible, semi-non-combustible, or flame-retardant, and a flame retardant or the like may be blended into the adhesive used. The thickness of the adhesive layer is, for example, 5 to 400 μm, preferably 10 to 150 μm.

[0065] The thickness of the tape-like member 4 is not particularly limited, but is, for example, 0.1 to 10 mm, preferably 0.5 to 5 mm.

[0066] When the tape-like member 4 has a multi-layer structure, it may have a two-layer structure, or may have a three-layer or more structure. Examples of the two-layer structure include those having structures such as a non-combustible material layer / fire-resistant material layer, non-combustible material layer / adhesive layer, fire-resistant material layer / adhesive layer, base material / fire-resistant material layer, base material / non-combustible material layer. In addition, as the three-layer structure having an adhesive layer, examples include a non-combustible material layer / fire-resistant material layer / adhesive layer, base material / fire-resistant material layer / adhesive layer, base material / non-combustible material layer / adhesive layer. Also, as the three-layer structure, those without an adhesive layer such as a non-combustible material layer / base material / fire-resistant material layer, base material / non-combustible material layer / fire-resistant material layer, base material / fire-resistant material layer / non-combustible material layer are also included. In addition, as the structure of four layers or more, examples include those in which an adhesive layer is further provided as the outermost layer of the three-layer structure without the above adhesive layer. Typically, adhesive layer / non-combustible material layer / base material / fire-resistant material layer, non-combustible material layer / base material / fire-resistant material layer / adhesive layer, base material / non-combustible material layer / fire-resistant material layer / adhesive layer, base material / fire-resistant material layer / non-combustible material layer / adhesive layer, etc. are included. In addition, in the above multi-layer structure, the non-combustible material layer and the fire-resistant material layer, the non-combustible material layer and the base material, and the fire-resistant material layer and the base material adjacent to each other may be adhered by a known adhesive. Therefore, in each of the above laminated structures, an adhesive layer may be provided between the above layers. In the multilayer structure, the tape-shaped member 4 may have the same layer structure throughout, or may have a partially different structure. For example, the adhesive layer may be provided on a part of the tape-shaped member 4, with a part having a single-layer structure and a part having a multilayer structure.

[0067] The tape-shaped member 4 wound around the outer periphery of the inserted body 21 is preferably in close contact with the inserted body 21 and may be appropriately deformed according to the shape of the inserted body 21. Further, the tape-shaped member 4 is fixed to the outer peripheral surface of the inserted body 21. Here, the tape-shaped member 4 may be fixed to the outer peripheral surface of the inserted body 21 by an adhesive layer or a refractory layer disposed on the inner peripheral side of the tape-shaped member 4. Further, the tape-shaped member 4 may be fixed to the inserted body 21 by a fixing member provided separately from the tape-shaped member 4. Examples of such a fixing member include a string-shaped member wound from the outer peripheral side of the tape-shaped member 4 or an adhesive tape. Further, the tape-shaped member 4 may be fixed to the inserted body 21 by a combination of two or more of these.

[0068] 〔Cover member〕 The cover member 5 is installed so as to cover the opening 13C of the partition through-hole 15 provided in the partition portion 11. Here, in the present embodiment, as long as the cover member 5 is disposed at a position covering the opening 13C, there may be another member between the cover member 5 and the opening 13C. In the present embodiment, the tape-shaped member 4 is disposed between the cover member 5 and the opening 13C, and the opening 13C is covered via the tape-shaped member 4. That is, the cover member 5 in the present embodiment covers the tape-shaped member 4 and closes a part of the gap 13E not blocked by the tape-shaped member 4. With the above configuration, the entire gap 13E between the opening 13C of the partition through-hole 15 and the inserted body 21 is blocked by the tape-shaped member 4 and the cover member 5. The cover member 5 is sheet-shaped and deformable, so that it can easily cover the tape-shaped member 4, surround the inserted body 21 while being in close contact with the inserted body 21, and easily close a part of the gap 13E not blocked by the tape-shaped member 4.

[0069] As shown in FIG. 9, the second cover portion 51 of the cover member 5 is disposed on the outer surface 11A. Then, the second cover portion 51 of the cover member 5 is fastened to the partition through portion 15 by inserting the fastening member 6A into the partition portion 11 of the partition through portion 15 from the second marks 53A to 53D. The first cover portion 50 of the cover member 5 is disposed so as to cover the tape-shaped member 4. Then, the first cover portion 50 of the cover member 5 surrounds the inserted body 21 in contact therewith, and is fastened to the inserted body 21 in a form that is suppressed and fixed by the fastening member 6B from the outside along the first mark 52 attached to the first cover portion 50.

[0070] The cover member 5 preferably covers the tape-shaped member 4 and makes the tape-shaped member 4 invisible from the outside. By making the tape-shaped member 4 invisible by the cover member 5, the opening 13C for installing the tape-shaped member 4 is covered, the design property of the partition through portion 15 can be improved, and the fire resistance of the partition through portion 15 can be improved.

[0071] According to the configuration of the present embodiment described above, the gap 13E inside the opening 13C of the partition through portion 15 is blocked by the tape-shaped member 4 and the cover member 5, and at least one of them has a refractory material. Therefore, appropriate fire protection performance can be imparted to the partition through portion treatment structure 10. Also, as described above, the partition through portion treatment structure 10 is installed by winding the tape-shaped member 4 around the inserted body 21 for one or more turns so as to block at least a part of the gap 13E between the opening 13C of the partition through portion 15 and the inserted body 21 by the tape-shaped member 4. Next, the cover member 5 is installed so as to cover the tape-shaped member 4, and the second cover portion 51 is fixed to the partition through portion 15 by inserting the fastening member 6A from the second mark attached to the second cover portion 51 of the cover member 5 into the partition portion 11 of the partition through portion 15. Then, the first cover portion 50 of the cover member 5 is wound around the inserted body 21 and fixed to the inserted body 21 by the fastening member 6B along the first mark 52 attached to the first cover portion 50, so that the construction can be performed. Therefore, the construction is easy and reliable, and it is possible to visually grasp whether the construction has been performed reliably. In addition, in the present embodiment, since the fireproof structure is formed by the tape-shaped member 4 and the cover member 5 without arranging filling materials such as fireproof putty and rock wool inside the partition penetration portion 15, there is no variation caused by the operator.

[0072] Furthermore, in the present embodiment, at least the cover member 5 and the retaining members 6A and 6B are exposed and visible from the outside. Also, the tape-shaped member 4 may be arranged at a position visible from the outside. And inside the partition penetration portion 15, no member other than the inserted body 21 is provided. Therefore, it is possible to easily inspect whether the partition penetration treatment material has been constructed as specified by visual inspection or photographing. Also, it is less likely to occur that the construction is forgotten.

[0073] [Third Embodiment] Next, the third embodiment of the present invention will be described in detail. In the third embodiment, the difference from the first and second embodiments is that, as shown in FIGS. 10 and 11, the partition penetration treatment material includes a sheet-shaped member 3, a tape-shaped member 4, and a cover member 5. Hereinafter, the differences between the third embodiment and the first and second embodiments will be described. Also, the parts where the description is omitted are the same as those in the first embodiment. Also, in the following description, the same reference numerals are given to the members having the same configuration as those in the first and second embodiments. Note that the details of the structures of the sheet-shaped member 3, the tape-shaped member 4, and the cover member 5 themselves are the same as those in the first and second embodiments, and at least one of the sheet-shaped member 3, the tape-shaped member 4, and the cover member 5 has a refractory material.

[0074] As shown in FIGS. 10 and 11, the sheet-shaped member 3 is installed in contact with the inserted body 21 and the partition portion 11. And as shown in FIGS. 10 and 11, the tape-shaped member 4 is wound around the outer periphery of the inserted body 21 for one or more turns. Thereby, an end face 4A is formed on the tape-shaped member 4, and the end face 4A can block at least a part of the gap 13E between the opening 13C and the inserted body 21. With the above configuration, a gap may be provided between the sheet-like member 3 and the inserted body 21, but such a gap is blocked by the tape-like member 4 and the cover member 5. Therefore, the entire gap 13E between the opening 13C of the partition through-hole 15 and the inserted body 21 is blocked by the sheet-like member 3, the tape-like member 4, and the cover member 5.

[0075] The cover member 5 is installed so as to cover the opening 13C of the partition through-hole 15 provided in the partition portion 11. Here, in the present embodiment, as long as the cover member 5 is disposed at a position covering the opening 13C, there may be another member between the cover member 5 and the opening 13C. In the present embodiment, the sheet-like member 3 and the tape-like member 4 are disposed between the cover member 5 and the opening 13C, and the opening 13C is covered via the sheet-like member 3 and the tape-like member 4. That is, the cover member 5 in the present embodiment covers the sheet-like member 3 and the tape-like member 4 and closes a part of the gap 13E that is not blocked by the sheet-like member 3 and the tape-like member 4. The cover member 5 is sheet-like and deformable, so that it can easily cover the sheet-like member 3 and the tape-like member 4, and while closely adhering to the inserted body 21, it surrounds the inserted body 21, making it possible to easily close a part of the gap 13E that is not blocked by the sheet-like member 3 and the tape-like member 4.

[0076] The cover member 5 can be configured to cover the surface 3A on the side opposite to the surface 3B facing the partition portion 11 of the sheet-like member 3. The cover member 5 can similarly be configured to cover the tape-like member 4. By covering at least one of the surface 3A of the sheet-like member 3 and the tape-like member 4 with the cover member 5, the function of suppressing the residue fall of the sheet-like member 3 and the tape-like member 4 can be exerted, and the fire resistance of the partition through-hole 15 can be improved.

[0077] The cover member 5 is preferably installed so as to be in contact with the inserted body 21 and the partition portion 11. By installing the cover member 5 so as to be in contact with the inserted body 21 and the partition portion 11, the opening 13C of the partition portion 11 can be blocked, and the fire resistance performance can be improved.

[0078] According to the configuration of the present embodiment described above, the gap 13E inside the opening 13C of the partition penetration portion 15 is blocked by at least one of the sheet-like member 3, the tape-like member 4, and the cover member 5, and at least one of these has a refractory material. Therefore, appropriate fire prevention performance can be imparted to the partition penetration portion treatment structure 10. Also, as described above, the partition penetration treatment structure 10 installs the sheet-like member 3 so as to block at least a part of the gap 13E between the opening 13C of the partition penetration portion 15 and the inserted body 21. Next, the tape-like member 4 is wound around the inserted body 21 for one week or more, and the tape-like member 4 is installed so as to block at least a part of the gap 13E between the opening 13C of the partition penetration portion 15 and the inserted body 21. Next, the cover member 5 is installed so as to cover both the sheet-like member 3 and the tape-like member 4, and the retaining material 6A is inserted into the partition portion 11 of the partition penetration portion 15 from the second mark attached to the second cover portion 51 of the cover member 5, thereby fixing the second cover portion 51 to the partition penetration portion 15. Then, the first cover portion 50 of the cover member 5 is wound around the inserted body 21, and it can be constructed by fixing it to the inserted body 21 with the retaining material 6B along the first mark 52 attached to the first cover portion 50. Therefore, the construction is easy and reliable, and it is possible to visually grasp whether the construction has been carried out reliably. Also, in the present embodiment, since the fire prevention structure is formed by the sheet-like member 3, the tape-like member 4, and the cover member 5 without arranging filling materials such as refractory putty and rock wool inside the partition penetration portion 15, there is no variation caused by the operator.

[0079] Furthermore, in the present embodiment, at least the cover member 5 and the fixing members 6A and 6B are exposed and visible from the outside. Also, part of the sheet-like member 3 and the tape-like member 4 may be arranged at positions where they are visible from the outside. And inside the partition penetration portion 15, no member other than the inserted body 21 is provided. Therefore, it is possible to easily check by visual inspection or photographing whether the partition penetration treatment material has been constructed as specified. Also, it is less likely to occur that the construction is forgotten.

[0080] [Other Embodiments] The present invention is not limited to the configurations of the above-described first to third embodiments, and any improvements and modifications may be made without departing from the technical idea of the present invention.

[0081] For example, in each of the above embodiments, the fixing members 6A and 6B are shown as being fastened from the outside of the cover member 5, but it is not necessarily required to fasten from the outside. For example, an adhesive, an adhesive agent, an adhesive tape, etc. may be used as the fixing member and arranged inside the second cover portion 51 (that is, on the partition portion 11 side) to fasten the second cover portion 51 of the cover member 5. In this case, the fixing member 6A for fastening from the outside of the second cover portion 51 may be omitted or used in combination. Similarly, an adhesive, an adhesive agent, an adhesive tape, etc. may be used as the fixing member and arranged inside the first cover portion 50 (that is, on the inserted body side) to fasten the first cover portion 50 of the cover member 5 to the inserted body. Also in this case, the fixing member 6B for fastening from the outside of the first cover portion 50 may be omitted or used in combination. The adhesive, adhesive agent, and adhesive tape used as the fixing member are preferably any of a non-combustible material, a semi-non-combustible material, or a flame-retardant material, and it is preferable to blend a flame retardant or the like into the adhesive, adhesive agent, etc.

[0082] However, in the present invention, it is preferable to use the fixing member 6A for fastening from the outside of the second cover portion 51. Similarly, it is preferable to use the fixing member 6B for fastening from the outside of the first cover portion 50. By fastening the cover portion from the outside, the fixing member can be easily installed at the specified position, and it can be easily confirmed visually that it has been installed at the specified position.

[0083] Further, in the present invention, as long as marks (first mark 52 and second mark 53) are provided on the cover member 5, either one of the first mark 52 and the second mark 53 may be omitted, but it is preferable to provide at least the second mark 53. By providing the second mark 53, the second cover portion 51 can be easily arranged at an appropriate position for the installation position of the fastening member 6A. When the installation position of the fastening member 6A is made appropriate, it is possible to effectively prevent the occurrence of a gap.

[0084] In addition to the first mark 52 and the second mark 53, the cover member 5 may be provided with characters, character information, or graphics. For example, together with the first mark 52 and the second mark 53, the size of the opening to which the present cover member 5 is applicable, the type of partition through-hole, the usage method of the cover member, a caution, etc. may be described.

[0085] For example, in each of the above embodiments, the partition through-treatment material may be connected to at least one of the sheet-like member 3 and the tape-like member 4 and have a member disposed inside the partition through-hole 15. Examples of such a member include a refractory material and accessories. As a specific example, a modified example of the first embodiment is shown in FIG. 12, and a modified example of the second embodiment is shown in FIG. 13. As the refractory material, for example, a block-shaped refractory material 70 as shown in FIGS. 12 and 13 is used, and the block-shaped refractory material 70 may be connected to the sheet-like member 3 or the tape-like member 4. The connection mode is not particularly limited. For example, it may be laminated on one surface of the sheet-like member 3 or the tape-like member 4, or may be connected to the end surface of the sheet-like member 3 or the tape-like member 4. The refractory material 70 preferably consists of a thermally expandable member that expands by heating as described above, and among them, it is preferably formed from a thermally expandable resin composition.

[0086] In the above description, the partition portion 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 provided, for example, it may be composed of a single wall material. Also, the partition portion 11 is not limited to the wall of a building and may be the ceiling or floor of a building. Even in the case of the ceiling or floor, the partition portion may have a structure with a hollow portion between two partition materials, or may have a structure without a hollow portion, and may be composed of, for example, a single partition material.

[0087] In addition, in each of the above embodiments, it has been described on the premise that partition penetration treatment materials with the same structure are provided at both openings 13C and 13D (that is, both sides of the partition portion 11) of the partition portion 11, but different partition penetration treatment structures may be provided at each of the openings 13C and 13D. For example, a partition penetration treatment structure according to the first embodiment may be provided at one opening 13C, and a partition penetration treatment structure according to the second embodiment may be provided at the other opening 13D. Also, the partition penetration treatment material at the opening 13D may be omitted.

[0088] Furthermore, in each of the above embodiments, an aspect in which at least one of the sheet-like member 3 and the tape-like member 4 is provided is also shown, but both may be omitted. When both are omitted, the cover member 5 may have a refractory material, but it is preferable that a refractory material other than the sheet-like member 3 and the tape-like member 4 is arranged inside the cover member 5. For example, a refractory material other than the sheet-like member 3 and the tape-like member 4 may be arranged between the cover member 5 and the partition portion 11. The refractory material may be arranged inside the partition penetration portion 15, for example, in the gap 13E between the opening 13C of the partition penetration portion 15 and the inserted body 21. Also, the refractory material other than the sheet-like member 3 and the tape-like member 4 is preferably formed of a thermally expandable resin composition, but may be a refractory putty or the like.
