Description

本発明は、建築物の仕切り部に設けられる床や壁等の区画体に区画貫通孔が形成され、該区画貫通孔に長尺体が挿通される区画貫通構造に用いられる措置具に関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a measure tool used in a partition penetrating structure in which a partition through-hole is formed in a partition such as a floor or a wall provided in a partition of a building, and a long body is inserted through the partition through-hole.

従来から、建築物の仕切り部に設けられる区画体に形成された貫通孔にスリーブを固定し、固定したスリーブの内部に媒体としての長尺体の一例である配管を挿通する。続いて、スリーブの内部に熱膨張性材料からなるシート状成形体を設置してから、スリーブの一方の端部を該スリーブの外面と配管の外面とに亘ってシール部材を貼り付けることでシールする（例えば特許文献１）。 Conventionally, a sleeve is fixed to a through-hole formed in a partition provided in a partition of a building, and a pipe, which is an example of a long body as a medium, is inserted through the fixed sleeve. Subsequently, a sheet-like molding made of a thermally expandable material is placed inside the sleeve, and then one end of the sleeve is sealed by sticking a sealing member across the outer surface of the sleeve and the outer surface of the pipe. (for example, Patent Document 1).

特開２００６－２９０２３号公報JP-A-2006-29023

上記特許文献１のシール部材では、前記配管（長尺体）が複数本である場合に、大小異なる径を有する複数本の配管が存在することが多いため、配管同士の間に生ずる谷間となる隙間が無くなるように、配管の外周面に沿わせることが難しい。そのため、配管同士の隙間を十分にシールすることができず、耐火性能が低下してしまい、早期改善が望まれている。 In the seal member of Patent Document 1, when there are a plurality of pipes (long bodies), there are often a plurality of pipes having different diameters, so a valley occurs between the pipes. It is difficult to make it follow the outer peripheral surface of the pipe so that there is no gap. As a result, the gaps between the pipes cannot be sufficiently sealed, and the fire resistance deteriorates, and early improvement is desired.

本発明は前述の状況に鑑み、解決しようとするところは、長尺体同士の隙間があっても確実に閉塞できる措置具を提供するものである。 SUMMARY OF THE INVENTION In view of the above-mentioned situation, the present invention aims to provide a treatment tool capable of reliably closing even if there is a gap between elongated bodies.

本発明の措置具は、前述の課題解決のために、建築物の区画体に区画貫通孔が形成され、該区画貫通孔に少なくとも１本の長尺体が挿通される区画貫通構造に用いられる措置具であって、前記区画貫通孔に挿通可能で、かつ、筒状のスリーブ部材と、該スリーブ部材に対して軸方向外方向きに延設され、かつ、該スリーブ部材を挿通する前記長尺体に対して縮径可能な筒状のカバー部材と、前記スリーブ部材の内面に配置される熱膨張材と、を備え、前記カバー部材は、軸方向の先端部に、周方向に間隔を空けて複数の切込みが形成され、周方向で隣り合う前記切込み同士の間が舌片状の閉塞片になっていることを特徴としている。 In order to solve the above-described problems, the fixture of the present invention is used in a partition through structure in which a partition through-hole is formed in a partition body of a building and at least one elongated body is inserted through the partition through-hole. A measuring tool, comprising: a tubular sleeve member that can be inserted into the partition through-hole; A cylindrical cover member that can be reduced in diameter with respect to the scale body, and a thermal expansion material disposed on the inner surface of the sleeve member are provided. It is characterized in that a plurality of cuts are formed with spaces therebetween, and tongue-like blocking pieces are formed between the cuts that are adjacent in the circumferential direction.

本発明によれば、カバー部材を長尺体に対して縮径させて長尺体を覆うと、長尺体同士に発生する隙間に舌片状の閉塞片が入り込む。これにより、長尺体同士の隙間を舌片状の閉塞片で確実に閉塞することができる。 According to the present invention, when the cover member is reduced in diameter with respect to the elongated body to cover the elongated body, the tongue-like blocking piece enters the gap generated between the elongated bodies. Thereby, the gap between the elongated bodies can be reliably closed by the tongue-shaped closing piece.

又、本発明の措置具として、前記切込みは、軸方向と交差する斜め切込みを含んでいてもよい。 Moreover, as a measure tool of the present invention, the cut may include an oblique cut that intersects with the axial direction.

上記のように、切込みが、軸方向と交差する斜め切込みを含んでいることによって、閉塞片における前記斜め切込みに対応する部分が軸方向に交差する斜め形状になるので、長尺体同士の隙間に閉塞片が入り込み易い。 As described above, since the incisions include oblique incisions intersecting with the axial direction, the portions of the blocking piece corresponding to the oblique incisions become oblique shapes intersecting in the axial direction. Obstruction pieces are likely to enter into.

又、本発明の措置具として、前記切込みは、前記斜め切込みの先端側に軸方向に沿う直線切込みを含んでいてもよい。 Moreover, as a measure tool of the present invention, the cut may include a linear cut along the axial direction on the tip side of the oblique cut.

上記のように、切込みが、斜め切込みと斜め切込みの先端側に軸方向に沿う直線切込みとを含んでいることによって、閉塞片が斜め切込みに対応する部分が斜め形状となりつつ、この先端側の直線切込みに対応する部分が軸方向に沿った直線形状となるので、長尺体同士の隙間に閉塞片が入り込んで長尺体の間の隙間を確実に閉塞する。 As described above, the incision includes an oblique incision and a linear incision along the axial direction on the tip side of the oblique incision, so that the portion of the blocking piece corresponding to the oblique incision has an oblique shape, while the tip side of the oblique incision becomes oblique. Since the portion corresponding to the linear cut has a linear shape along the axial direction, the closing piece enters the gap between the elongated bodies to reliably close the gap between the elongated bodies.

又、本発明の措置具として、前記カバー部材の先端部は、縮径形状を保形する保形手段が設けられていてもよい。 Further, as the measuring tool of the present invention, the tip portion of the cover member may be provided with a shape retaining means for retaining a reduced diameter shape.

上記のように、カバー部材の先端部は、縮径形状を保形する保形手段が設けられていることによって、カバー部材の先端部が縮径形状を維持しやすく、舌片状の閉塞片が長尺体同士の隙間に入り込んだ姿勢を維持しやすい。 As described above, the distal end portion of the cover member is provided with the shape-retaining means for retaining the reduced-diameter shape. It is easy to maintain a posture in which the body enters the gap between the long bodies.

又、本発明の措置具して、前記保形手段は、前記カバー部材の先端部を重ね構造とすることで形成されていてもよい。 Further, in the measuring tool of the present invention, the shape-retaining means may be formed by stacking the tip portion of the cover member.

上記のように、保形手段は、カバー部材の先端部を重ね構造とすることで形成されることによって、カバー部材の先端部の保形性能を高めることができる。これにより、舌片状の閉塞片が長尺体同士の隙間に入り込んだ姿勢を維持しやすい。 As described above, the shape-retaining means is formed by stacking the tip portion of the cover member, thereby enhancing the shape-retaining performance of the tip portion of the cover member. As a result, it is easy to maintain a posture in which the tongue-shaped blocking piece enters the gap between the elongated bodies.

又、本発明の措置具は、前記保形手段は、前記カバー部材の先端部に、縮径形状を維持する線材が設けられていてもよい。 Further, in the measuring tool of the present invention, the shape-retaining means may be provided with a wire that maintains a reduced-diameter shape at the distal end portion of the cover member.

上記のように、カバー部材の先端部に、縮径形状を維持する線材を設けることで、カバー部材の先端部の保形性能を高めることができる。 As described above, by providing the wire rod that maintains the reduced diameter shape at the distal end portion of the cover member, the shape retention performance of the distal end portion of the cover member can be enhanced.

又、本発明の措置具は、前記カバー部材が、前記長尺体に対して非接着であってもよい。 Further, in the measuring instrument of the present invention, the cover member may be non-bonded to the elongated body.

長尺体が熱膨張又は熱収縮により伸縮した場合に、カバー部材が、長尺体に対して非接着であると、長尺体の伸縮を許容しながら、舌片状の閉塞片が長尺体同士の隙間に入り込んだ姿勢を維持しやすい。 When the elongated body expands and contracts due to thermal expansion or thermal contraction, if the cover member is not adhered to the elongated body, the tongue-like blocking piece can be elongated while allowing the elongated body to expand and contract. It is easy to maintain a posture that enters the gap between the bodies.

本発明によれば、周方向で隣り合う切込み同士の間が舌片状の閉塞片になっていることによって、長尺体同士の隙間があっても確実に閉塞できる措置具を提供することができる。 ADVANTAGE OF THE INVENTION According to the present invention, it is possible to provide a treatment tool that can reliably close even if there is a gap between elongated bodies by forming a tongue-shaped blocking piece between the cuts that are adjacent in the circumferential direction. can.

以下、本発明の区画貫通構造に用いられる措置具の実施形態を図面に基づいて説明する。 Hereinafter, an embodiment of a treatment tool used in the compartment penetrating structure of the present invention will be described based on the drawings.

区画貫通構造では、建築物の仕切り部に設けられる区画体である床又は壁に区画貫通孔が形成され、区画貫通孔に長尺体が挿通される。前記挿通された長尺体と区画貫通孔との間には、隙間が発生しており、この隙間をなくすために措置具が用いられる。この実施形態では、壁を例に挙げて説明する。 In the partition penetration structure, a partition through-hole is formed in a floor or a wall, which is a partition body provided in a partition part of a building, and a long body is inserted through the partition through-hole. A gap is generated between the inserted long body and the partition through-hole, and a tool is used to eliminate this gap. In this embodiment, a wall will be described as an example.

措置具Ｈは、図１～図３に示すように、大きさが異なる３本の長尺体である配管１Ａ，１Ｂ，１Ｃに外装されるとともに壁（区画体）２に形成された円形の区画貫通孔３に挿入可能に構成される円筒状のスリーブ部材４と、スリーブ部材４に対して軸方向外方向きに延設され、かつ、スリーブ部材４を挿通する複数（図３では３本）の配管１Ａ，１Ｂ，１Ｃに対して縮径可能な円筒状のカバー部材５と、を備えている。尚、前記配管１Ａ，１Ｂ，１Ｃのうちの２本の配管１Ａ，１Ｂには、断熱材６Ａ，６Ｂが巻き付けられている。前記長尺体としては、冷媒管、熱媒管、給湯管、給水管、排水管、油圧配管、ガス管、電線管、電線（電源線や信号線）、ケーブル等が挙げられる。壁２は、２枚の壁２Ａ，２Ｂが軸方向に間隔を置いて設置されて内部中空の壁に構成されている。 As shown in FIGS. 1 to 3, the measuring tool H is mounted on three elongated pipes 1A, 1B, and 1C of different sizes, and has a circular shape formed on a wall (partition) 2. A cylindrical sleeve member 4 configured to be insertable into the partition through-hole 3, and a plurality of (three in FIG. ), and a cylindrical cover member 5 whose diameter can be reduced for the pipes 1A, 1B, and 1C. Two pipes 1A, 1B out of the pipes 1A, 1B, 1C are wrapped with heat insulating materials 6A, 6B. Examples of the elongated body include refrigerant pipes, heat medium pipes, hot water supply pipes, water supply pipes, drain pipes, hydraulic pipes, gas pipes, electric wire pipes, electric wires (power lines and signal lines), cables, and the like. The wall 2 is composed of two walls 2A and 2B spaced apart in the axial direction to form an internal hollow wall.

スリーブ部材４は、金属製（例えば、鋼製）の薄板状体をリング状に丸めることで円筒状に構成されるスリーブ本体４１と、スリーブ本体４１の内面４１Ａに貼り付けられる熱膨張材４２と、スリーブ本体４１の軸方向一端部（図２では右側端部）の外面４１Ｂに貼り付けられる隙間隠し部４３と、を備えている。したがって、スリーブ本体４１を区画貫通孔３の内径寸法に対応した外径寸法になるように丸めることで区画貫通孔３に挿通可能に構成できる。スリーブ本体４１を区画貫通孔３に挿通した後は、縮径させたスリーブ本体４１が弾性復元力により外側に拡開することによって、スリーブ本体４１を区画貫通孔３に押し付けてスリーブ本体４１と区画貫通孔３との間に隙間が発生することがなく、スリーブ本体４１と区画貫通孔３とを遮蔽することができる。 The sleeve member 4 includes a cylindrical sleeve main body 41 formed by rolling a metal (for example, steel) thin plate into a ring shape, and a thermal expansion material 42 attached to the inner surface 41A of the sleeve main body 41. , and a gap hiding portion 43 attached to the outer surface 41B of the sleeve main body 41 at one axial end (the right end in FIG. 2). Therefore, by rounding the sleeve body 41 so as to have an outer diameter dimension corresponding to the inner diameter dimension of the partitioned through-hole 3 , the sleeve body 41 can be configured to be inserted into the partitioned through-hole 3 . After the sleeve main body 41 is inserted through the partitioning through-hole 3 , the sleeve main body 41 with its reduced diameter expands outward due to its elastic restoring force, thereby pressing the sleeve main body 41 against the partitioning through-hole 3 and partitioning the sleeve main body 41 . The sleeve main body 41 and the partitioning through-hole 3 can be shielded without creating a gap with the through-hole 3 .

また、スリーブ本体４１は、軸方向と直交する周方向の寸法が、区画貫通孔３の直径寸法よりも大きな寸法を有し、軸方向の寸法が区画貫通孔３の軸方向の寸法よりも長い寸法を有している。また、スリーブ本体４１には、図４に示すように、スリーブ本体４１に貼り付けられた熱膨張材４２の軸方向略中央部付近に、周方向全周に亘って間隔を置いて複数の長孔４１ａ，４１ｂが２列形成されている。これら２列の長孔４１ａ，４１ｂは、それぞれ平行に形成され、かつ、千鳥状に配置され、しかも、周方向で隣り合う一方（図４の上側）の長孔４１ａと他方（図４の下側）の長孔４１ｂとが軸方向で重複するように長さが設定されている。つまり、スリーブ本体４１の周方向のどの部分においても長孔４１ａ又は４１ｂが存在する。したがって、熱膨張材４２が膨張した場合に、長孔４１ａ，４１ｂを通してスリーブ本体４１の外部側へ熱膨張材４２の一部が膨出して、壁２の貫通孔３とスリーブ本体４１の外面との隙間を埋めることができるようになっている。 In addition, the sleeve body 41 has a dimension in the circumferential direction orthogonal to the axial direction that is larger than the diameter dimension of the partitioning through-hole 3, and an axial dimension that is longer than the axial dimension of the partitioning through-hole 3. have dimensions. In addition, as shown in FIG. 4, the sleeve body 41 has a plurality of elongated portions spaced apart along the entire circumference in the vicinity of the substantially central portion in the axial direction of the thermal expansion material 42 attached to the sleeve body 41 . Two rows of holes 41a and 41b are formed. These two rows of elongated holes 41a and 41b are formed parallel to each other and arranged in a zigzag pattern. The length is set so that it overlaps with the long hole 41b on the side) in the axial direction. In other words, the long hole 41a or 41b exists at any portion of the sleeve body 41 in the circumferential direction. Therefore, when the thermal expansion material 42 expands, a part of the thermal expansion material 42 bulges to the outside of the sleeve body 41 through the long holes 41 a and 41 b, and the through hole 3 of the wall 2 and the outer surface of the sleeve body 41 . It is designed to be able to fill the gap between

熱膨張材４２は、スリーブ本体４１の軸方向と直交する周方向全域に亘る周方向の寸法を有し、軸方向一端から軸方向他端までの軸方向全域に亘る寸法を有している。したがって、スリーブ本体４１が区画貫通孔３内に挿通された状態において、熱膨張材４２の軸方向一端及び軸方向他端の両方とも区画貫通孔３の軸方向外側へ突出した状態になっている。尚、この実施形態では、熱膨張材４２を、スリーブ本体４１の軸方向一端から軸方向他端までの軸方向全域に亘る寸法にしたが、軸方向全域よりも短い寸法にしてもよい。 The thermal expansion material 42 has a circumferential dimension across the entire circumferential direction perpendicular to the axial direction of the sleeve body 41, and has a dimension covering the entire axial direction from one axial end to the other axial end. Therefore, when the sleeve body 41 is inserted into the partition through-hole 3 , both the one axial end and the other axial end of the thermal expansion member 42 protrude axially outward of the partition through-hole 3 . . In this embodiment, the thermal expansion member 42 has a dimension extending from one axial end to the other axial end of the sleeve body 41 in the axial direction, but it may have a dimension shorter than the entire axial direction.

また、熱膨張材４２は、熱膨張性（加熱により体積が増加する性質）と耐火性（熱に耐えやすい性質、溶融温度が高く燃えにくい性質）とを有する部材である。熱膨張材４２としては、公知の材質のものを特に制限なく用いることができ、例えばパテ状部材（熱膨張性パテ状耐火材）を用いることができる。また、熱膨張材４２は、例えば所定温度（例えば１８０℃）以上に加熱された際に、その厚み方向に膨張して配管１Ａ，１Ｂ，１Ｃの外面（２本の配管１Ａ，１Ｂは、断熱材６Ａ，６Ｂの外面１ａ，１ｂ、残る配管１Ｃの外面１ｃ）とスリーブ本体４１の内面４１Ａとの間の隙間を埋めることで区画貫通孔３の一方側で発生した火炎が区画貫通孔３の他方側へ移動することを防止する。このように、スリーブ部材４が熱膨張材４２を含むことで、スリーブ部材４が熱膨張性を有することとなる。 The thermal expansion material 42 is a member having thermal expansibility (the property of increasing its volume when heated) and fire resistance (the property of easily withstanding heat, having a high melting temperature and being difficult to burn). As the thermal expansion material 42, known materials can be used without particular limitation, and for example, a putty-like member (thermally expansible putty-like refractory material) can be used. In addition, when the thermal expansion material 42 is heated to a predetermined temperature (for example, 180° C.) or more, it expands in the thickness direction and the outer surfaces of the pipes 1A, 1B, 1C (the two pipes 1A, 1B are heat-insulated). By filling the gap between the outer surfaces 1a and 1b of the members 6A and 6B, the outer surface 1c of the remaining pipe 1C, and the inner surface 41A of the sleeve body 41, the flame generated on one side of the partitioned through-hole 3 is prevented from reaching the partitioned through-hole 3. Prevents movement to the other side. Since the sleeve member 4 contains the thermal expansion material 42 in this manner, the sleeve member 4 has thermal expansion properties.

隙間隠し部４３は、例えば、スポンジ、柔らかいゴム、発泡ポリウレタン等発泡材などの復元可能に変形可能な帯状の弾性部材から構成され、貫通孔３とスリーブ本体４１の外面との間の隙間を隠す目的で使用されているが、スリーブ本体４１を区画貫通孔３内に挿入したときに、区画貫通孔３を構成する一方の壁２Ａの壁面２ａに当接して区画貫通孔３内に対するスリーブ本体４１の位置決めを行うためのストッパとしても機能する。 The gap hiding part 43 is composed of a band-like elastic member that can be deformed in a reversible manner, such as sponge, soft rubber, foamed polyurethane foam, etc., and hides the gap between the through hole 3 and the outer surface of the sleeve body 41. When the sleeve main body 41 is inserted into the partition through-hole 3, the sleeve main body 41 abuts against the wall surface 2a of one of the walls 2A constituting the partition through-hole 3, thereby preventing the sleeve main body 41 from inside the partition through-hole 3. It also functions as a stopper for positioning.

また、隙間隠し部４３は、スリーブ本体４１の軸方向一端部の外面に接着剤により貼り付けられている。そして、スリーブ本体４１を縮径した際にその縮径状態を維持することができるようにスリーブ本体４１の外面に貼り付けることができるようにしている。具体的には、図４に示すように、隙間隠し部４３の一端部が、スリーブ本体４１の一端部から周方向外側に延出する延出部４３Ａを備え、かつ、隙間隠し部４３の他端部がスリーブ本体４１の他端部よりも一端部側に位置するように、隙間隠し部４３がスリーブ本体４１に貼り付けられている。したがって、スリーブ本体４１を区画貫通孔３内に挿入できる外径寸法になるように縮径した状態で、隙間隠し部４３の延出部４３Ａをスリーブ本体４１の他端部の外面に貼り付けることによって、スリーブ本体４１を縮径した状態を維持できる。尚、延出部４３Ａの内面には、接着剤（図示せず）が塗布され、その接着剤が剥離紙（図示せず）で覆われており、延出部４３Ａをスリーブ本体４１の他端部の外面に貼り付ける際には、隙間隠し部４３の延出部４３Ａの先端と隙間隠し部４３の他端との間に隙間が発生しないように、延出部４３Ａを切断して周方向の長さ調整を行ったうえで剥離紙を外して隙間隠し部４３の延出部４３Ａをスリーブ本体４１の他端部の外面に貼り付けて、スリーブ本体４１を縮径した状態を維持するとともに、途切れることがない環状の隙間隠し部４３を構成する（図３参照）。 Further, the gap hiding portion 43 is adhered to the outer surface of one axial end portion of the sleeve body 41 with an adhesive. And, when the diameter of the sleeve body 41 is reduced, it can be attached to the outer surface of the sleeve body 41 so that the diameter-reduced state can be maintained. Specifically, as shown in FIG. 4, one end of the gap hiding portion 43 includes an extension portion 43A extending outward in the circumferential direction from one end of the sleeve body 41, The gap-hiding part 43 is attached to the sleeve body 41 so that the end is located closer to one end than the other end of the sleeve body 41 . Therefore, the extending portion 43A of the gap hiding portion 43 can be attached to the outer surface of the other end of the sleeve main body 41 in a state where the outer diameter of the sleeve main body 41 is reduced so that it can be inserted into the partitioning through-hole 3. Therefore, the state where the diameter of the sleeve body 41 is reduced can be maintained. An adhesive (not shown) is applied to the inner surface of the extending portion 43A, and the adhesive is covered with a release paper (not shown). When attaching to the outer surface of the part, the extending part 43A is cut so as not to create a gap between the tip of the extending part 43A of the gap hiding part 43 and the other end of the gap hiding part 43. After adjusting the length, the release paper is removed and the extended portion 43A of the gap hiding portion 43 is attached to the outer surface of the other end of the sleeve main body 41 to maintain the reduced diameter state of the sleeve main body 41. , constitutes an uninterrupted annular gap hiding portion 43 (see FIG. 3).

カバー部材５は、例えば難燃性を有する１枚のアルミガラスクロスから構成されたカバー本体５１と、カバー本体５１の先端部側の内面に備えるカバー側熱膨張材５２と、カバー側熱膨張材５２よりも先端側に配置され先端部を縮径形状に保形するための保形手段５３と、該保形手段５３をカバー本体５１の内面に固定し、かつ、配管１Ａ，１Ｂ，１Ｃとカバー本体５１の内面５１Ａとの間の隙間を埋めるための発泡材５４と、を備えている。 The cover member 5 includes a cover main body 51 made of, for example, a sheet of flame-retardant aluminum glass cloth, a cover-side thermal expansion material 52 provided on the inner surface of the cover main body 51 on the tip side, and a cover-side thermal expansion material. A shape-retaining means 53 arranged on the distal end side of 52 for retaining the shape of the distal end portion in a reduced diameter shape; and a foam material 54 for filling the gap between the cover main body 51 and the inner surface 51A.

図１に示すように、カバー本体５１の軸方向の先端部に、周方向に間隔を空けて複数の切込み５５を形成することによって、周方向で隣り合う切込み５５，５５同士の間が舌片状の閉塞片５６に構成されている。また、カバー本体５１の基端部が、スリーブ本体４１の軸方向一端部の外面に周方向全域に亘って接着剤により貼り付けられている。そして、カバー本体５１の周方向一端部には、スリーブ本体４１の周方向一端部から周方向外側に延びる延出部５１Ｂを備えている。したがって、スリーブ本体４１をリング状に丸めて縮径させた時に、カバー本体５１の重ね合わせ部分で隙間が発生しないように、延出部５１Ｂをカバー本体５１の周方向他端部の外面５１Ｃに接着剤により貼り付けている。尚、延出部５１Ｂの内面５１ｂに接着剤（図示せず）が塗布されていて、図示していない剥離紙が取り付けられている。そして、延出部５１Ｂをスリーブ本体４１の周方向他端部の外面に貼り付ける際に、剥離紙を剥すことになる。 As shown in FIG. 1 , by forming a plurality of cuts 55 at intervals in the axial direction of the cover main body 51 , the gap between the cuts 55 , 55 adjacent in the circumferential direction is a tongue piece. The closure piece 56 is configured in the shape of a Also, the base end of the cover body 51 is adhered to the outer surface of one axial end of the sleeve body 41 with an adhesive over the entire circumferential direction. One circumferential end of the cover main body 51 is provided with an extending portion 51B extending outward from the one circumferential end of the sleeve main body 41 in the circumferential direction. Therefore, when the sleeve body 41 is rolled into a ring shape to reduce its diameter, the extending portion 51B is formed on the outer surface 51C of the cover body 51 at the other end in the circumferential direction so as not to create a gap at the overlapped portion of the cover body 51. It is attached with an adhesive. An adhesive (not shown) is applied to the inner surface 51b of the extending portion 51B, and a release paper (not shown) is attached. Then, when the extending portion 51B is attached to the outer surface of the sleeve main body 41 at the other end in the circumferential direction, the release paper is peeled off.

各切込み５５は、軸方向と交差する斜め切込み５５Ａと、斜め切込み５５Ａの先端側に軸方向に沿う直線切込み５５Ｂと、を備えている。更に詳細に説明すれば、図６（ａ）に示すように、軸方向に沿う２倍の長さの直線切込み５５Ｂと、直線切込み５５Ｂの軸方向両端のそれぞれから軸方向と交差する斜め切込み５５Ａ，５５Ａと、を形成し、２倍の直線切込み５５Ｂの長さ方向半分の長さの時点の折り返し部５５Ｃ（点線参照）で折り返すことで２枚の閉塞片５６，５６からなる重ね構造を構成している（図６（ｂ）参照）。このようにカバー本体５１の先端部を重ね構造とすることで、カバー本体５１の先端部を縮径形状にした時の該縮径形状を保形する前記保形手段５３を構成している。このように、切込み５５が、斜め切込み５５Ａと斜め切込み５５Ａの先端側に直線切込み５５Ｂとを含んでいることによって、閉塞片５６が斜め切込み５５Ａに対応する部分が斜め形状となりつつ、この先端側の直線切込み５５Ｂに対応する部分が軸方向に沿った直線形状となるので、配管１Ａ，１Ｂ，１Ｃ同士の隙間Ｓ（図３では３か所）に閉塞片５６が入り込んで配管１Ａ，１Ｂ，１Ｃの間の隙間Ｓを確実に閉塞する。これにより、耐火性能が低下することを防止できる。また、カバー本体５１の先端５５Ｔから直線切込み５５Ｂが始まっているので、作業者が折り返し部５５Ｃ（点線参照）で折り返す時に、多少ずれて折り返したとしても、ずれが目立ち難いだけでなく、先端５５Ｔに対して鋭角部ができないので、先端５５Ｔが尖ったり、毛羽立ち難くすることができる。 Each cut 55 includes an oblique cut 55A that intersects with the axial direction, and a straight cut 55B along the axial direction on the tip side of the oblique cut 55A. More specifically, as shown in FIG. 6(a), straight cuts 55B of double length along the axial direction and oblique cuts 55A crossing the axial direction from both ends of the straight cuts 55B in the axial direction. , 55A are formed, and are folded back at a folded portion 55C (see dotted line) at a point of half the length of the double linear cut 55B in the longitudinal direction, thereby forming a layered structure consisting of two blocking pieces 56, 56. (see FIG. 6(b)). By forming the front end portion of the cover main body 51 to have an overlapping structure in this way, the shape retaining means 53 for maintaining the diameter-reduced shape of the front end portion of the cover main body 51 is formed. In this way, the cut 55 includes the diagonal cut 55A and the straight cut 55B on the tip side of the diagonal cut 55A, so that the portion of the blocking piece 56 corresponding to the diagonal cut 55A has an oblique shape, while the tip side Since the portion corresponding to the linear cut 55B has a linear shape along the axial direction, the blocking piece 56 enters the gap S (three places in FIG. 3) between the pipes 1A, 1B, 1C to close the pipes 1A, 1B, To surely close a gap S between 1C. Thereby, it can prevent that fireproof performance falls. Further, since the straight cut 55B starts from the tip 55T of the cover main body 51, even if the worker folds the cover at the folding portion 55C (see the dotted line) with a slight deviation, the deviation is not only noticeable, but also the tip 55T. Since an acute angle portion is not formed with respect to the tip 55T, it is possible to make the tip 55T hard to sharpen or become fuzzy.

カバー側熱膨張材５２は、カバー本体５１の周方向全域に亘る寸法を有する帯状体から構成され、前記熱膨張材４２と同一の材料から構成されている。カバー側熱膨張材５２は、前述したように、例えば所定温度（例えば１８０℃）以上に加熱された際に、その厚み方向に膨張して配管１Ａ，１Ｂ，１Ｃの外面とカバー本体５１の内面５１Ａとの間の隙間を埋めることで区画貫通孔３の一方側で発生した火炎が区画貫通孔３の他方側へ移動することを防止する。 The cover-side thermal expansion member 52 is formed of a belt-like body having dimensions extending over the entire circumferential direction of the cover main body 51 and is formed of the same material as the thermal expansion member 42 . As described above, the cover-side thermal expansion member 52 expands in its thickness direction when heated to a predetermined temperature (for example, 180° C.), and the outer surfaces of the pipes 1A, 1B, and 1C and the inner surface of the cover body 51 expand. 51A prevents the flame generated on one side of the partitioning through-hole 3 from moving to the other side of the partitioning through-hole 3 .

保形手段５３は、カバー本体５１の先端部が縮径された状態を維持する線材としての金属製のワイヤ５３Ａから構成されている。このワイヤ５３Ａは、前述したように発泡材５４でカバー本体５１の先端部の内面に固定されており、スリーブ本体４１を縮径した（丸めた）ときに環状に構成され、カバー本体５１の先端部の保形性能を高めることができる。また、ワイヤ５３Ａを設けることで、カバー本体５１の先端部が縮径形状を維持しやすく、舌片状の閉塞片５６が配管１Ａ，１Ｂ，１Ｃ同士の隙間Ｓに入り込んだ姿勢を維持しやすい。この実施形態では、線材（ワイヤ５３Ａ）とカバー本体５１の先端部の重ね構造の両方を保形手段５３としているが、いずれか一方のみを設けて実施してもよい。 The shape-retaining means 53 is composed of a metal wire 53A as a wire material that maintains the diameter-reduced state of the front end portion of the cover body 51 . The wire 53A is fixed to the inner surface of the tip of the cover main body 51 by the foam material 54 as described above, and when the sleeve main body 41 is contracted (rolled), the wire 53A is formed into an annular shape, and the tip of the cover main body 51 It is possible to improve the shape retention performance of the part. Further, by providing the wire 53A, the front end portion of the cover body 51 can easily maintain the reduced diameter shape, and the tongue-shaped blocking piece 56 can easily maintain the posture in which it enters the gap S between the pipes 1A, 1B, and 1C. . In this embodiment, both the wire rod (wire 53A) and the overlapping structure of the front end portion of the cover body 51 are used as the shape retaining means 53, but only one of them may be provided.

発泡材５４は、例えば、１本の帯状のスポンジから構成されているが、柔らかいゴム、発泡ポリウレタン等発泡材などの復元可能に変形可能な帯状の弾性部材から構成されていてもよい。この発泡材５４は、カバー本体５１を縮径したときに、配管１Ａ，１Ｂ，１Ｃとカバー本体５１の内面５１Ａとの間の隙間を埋める。 The foam material 54 is composed of, for example, a strip of sponge, but may be composed of a reversibly deformable belt-shaped elastic member such as soft rubber or a foam material such as polyurethane foam. The foam material 54 fills the gaps between the pipes 1A, 1B, 1C and the inner surface 51A of the cover body 51 when the cover body 51 is contracted.

上記のように構成された措置具Ｈを区画貫通孔３に取り付けて配管１Ａ，１Ｂ，１Ｃ同士間の隙間Ｓを覆う手順について説明する。 A procedure for covering the gap S between the pipes 1A, 1B, and 1C by attaching the instrument H configured as described above to the partition through-hole 3 will be described.

まず、図４及び図５に示す措置具を用意し、措置具のスリーブ本体４１を丸めて区画貫通孔３に挿通可能な大きさになるように調整し、調整後に隙間隠し部４３の延出部４３Ａ（図４参照）をスリーブ本体４１の他端部の外面４１Ｂに貼り付けてスリーブ本体４１を縮径した状態を維持する。続いて、カバー本体５１の延出部５１Ｂ（図４、図５参照）をカバー本体５１の周方向他端部の外面５１Ｃ（図４、図５参照）に貼り付ける。こののち、区画貫通孔３に円筒状になったスリーブ本体４１をカバー部材５側とは反対側の基端側から挿通する。この挿通しているときに、スリーブ本体４１の隙間隠し部４３が区画貫通孔３の一方の壁２Ａの壁面２ａに当接する。これによりスリーブ本体４１の区画貫通孔３への挿通が完了する。 4 and 5 is prepared, the sleeve body 41 of the measure is rounded and adjusted so that it can be inserted into the partition through-hole 3, and after the adjustment, the gap hiding part 43 extends. The portion 43A (see FIG. 4) is adhered to the outer surface 41B of the other end of the sleeve body 41 to maintain the state where the diameter of the sleeve body 41 is reduced. Subsequently, the extending portion 51B (see FIGS. 4 and 5) of the cover body 51 is attached to the outer surface 51C (see FIGS. 4 and 5) of the cover body 51 at the other end in the circumferential direction. After that, the cylindrical sleeve body 41 is inserted through the partition through-hole 3 from the base end side opposite to the cover member 5 side. During this insertion, the gap hiding portion 43 of the sleeve body 41 contacts the wall surface 2a of one wall 2A of the partition through-hole 3. As shown in FIG. This completes the insertion of the sleeve body 41 into the partition through-hole 3 .

次に、措置具Ｈに配管１Ａ，１Ｂ，１Ｃを挿通させてから、カバー本体５１の先端部を縮径させてカバー本体５１の内面５１Ａを配管１Ａ，１Ｂ，１Ｃの外面１ａ，１ｂ，１ｃに当接させる（図１参照）。この時、閉塞片５６が径方向で隣り合う径の異なる配管１Ｂ，１Ｃ及び１Ｃ，１Ａ並びに１Ｂ，１Ａ同士間のそれぞれの隙間Ｓに入り込んで該隙間Ｓを確実に閉塞することができる（図３参照）。本発明では、カバー本体５１が配管１Ａ，１Ｂ，１Ｃに対して非接着であるため、配管１Ａ，１Ｂ，１Ｃが熱膨張又は熱収縮により伸縮した場合でも、カバー本体５１が、配管１Ａ，１Ｂ，１Ｃの伸縮を許容しながら、舌片状の閉塞片５６が配管１Ｂ，１Ｃ及び１Ｃ，１Ａ並びに１Ｂ，１Ａ同士の隙間Ｓに入り込んだ姿勢を維持しやすい。 Next, after the pipes 1A, 1B and 1C are passed through the measure H, the tip portion of the cover body 51 is reduced in diameter so that the inner surface 51A of the cover body 51 is aligned with the outer surfaces 1a, 1b and 1c of the pipes 1A, 1B and 1C. (see FIG. 1). At this time, the blocking piece 56 can enter the gaps S between the pipes 1B, 1C and 1C, 1A which are adjacent to each other in the radial direction and have different diameters, as well as between the pipes 1B, 1A, so that the gaps S can be reliably closed (Fig. 3). In the present invention, since the cover main body 51 is not adhered to the pipes 1A, 1B, 1C, even if the pipes 1A, 1B, 1C expand or contract due to thermal expansion or thermal contraction, the cover main body 51 is attached to the pipes 1A, 1B. , and 1C, it is easy to maintain the posture in which the tongue-shaped blocking piece 56 enters the gap S between the pipes 1B, 1C and 1C, 1A and between the pipes 1B, 1A.
