Description

本発明は、壁や床などの区画体により区画した隣の空間への延焼を防止できる耐火区画構造及びその構築方法に関する。 The present invention relates to a fireproof compartment structure capable of preventing the spread of fire to an adjacent space partitioned by a compartment such as a wall or a floor, and a method for constructing the same.

壁などの区画部で区画された複数の空間にわたって配管やケーブルなどの円筒状の長尺体を区画部の貫通孔に挿入して敷設する場合、一方の空間で発生した火災が区画部をはさんだ他方の空間へ延焼することを防止するため、貫通孔と長尺体の隙間に耐火材を埋める防火措置を行う必要がある。 When a long cylindrical body such as a pipe or cable is inserted into a through hole in a compartment and laid over multiple spaces partitioned by a compartment such as a wall, a fire that occurs in one of the spaces will blow the compartment. In order to prevent the fire from spreading to the other space, it is necessary to take fire prevention measures to fill the gap between the through hole and the long body with a fire resistant material.

従来の防火処理方法として、特許文献1に記載された方法が存在する。この方法は、防火区画体の孔に複数の長尺体を挿通した後、前記防火区画体により区画された複数の空間において、前記長尺体の周囲に、前記防火区画体の孔の長さより短く構成され、二つ割り状に形成された一対の筒体と、前記筒体の内面に取り付けられた熱膨張性耐火材シートと、前記筒体の一端に形成されるフランジ部から構成される防火処理部材を配置する。続いて、前記複数の空間で前記複数の長尺体を囲むようにして前記一対の筒体を結合した後、前記フランジ部が防火区画体の壁面に当接するまで防火処理具を孔に挿入する。この防火処理方法によれば、火災が発生した際に、火災にさらされて、熱膨張性耐火材シートが膨張し、複数の長尺体と孔との隙間を塞ぐことができる。 As a conventional fire protection treatment method, there is a method described in Patent Document 1. In this method, after inserting a plurality of elongated bodies into the holes of the fireproof compartment, in the plurality of spaces partitioned by the fireproof compartment, the length of the holes of the fireproof compartment is used around the elongated body. Fire protection treatment consisting of a pair of short cylinders formed in a split shape, a heat-expandable fireproof material sheet attached to the inner surface of the cylinder, and a flange portion formed at one end of the cylinder. Place the members. Subsequently, after connecting the pair of cylinders so as to surround the plurality of elongated bodies in the plurality of spaces, the fireproof treatment tool is inserted into the hole until the flange portion abuts on the wall surface of the fireproof compartment. According to this fire protection treatment method, when a fire breaks out, the heat-expandable refractory material sheet expands when exposed to the fire, and the gap between the plurality of elongated bodies and the holes can be closed.

特開平11-341649号公報Japanese Unexamined Patent Publication No. 11-341649

ところで、前記防火処理方法における複数の長尺体のうち、少なくとも一本は、内部に流体を通す流体管と、前記流体管の周囲を被覆する被覆材を備える複層長尺体が用いられることがある。また、前記複層長尺体における被覆材としては、ポリエチレンフォームなどの所定の温度で径外方向に膨張する部材が用いられることがある。 By the way, at least one of the plurality of elongated bodies in the fire prevention treatment method is a multi-layered elongated body provided with a fluid pipe through which a fluid is passed and a covering material covering the periphery of the fluid pipe. There is. Further, as the covering material in the multi-layered elongated body, a member such as polyethylene foam that expands in the outer diameter direction at a predetermined temperature may be used.

そのため、防火区画体により区画された複数の空間のうち、一方の空間で火災が発生すると、熱によって、被覆材が径外方向に膨張し、複数の長尺体同士の隙間が拡大する。そして、火災による圧力差や温度差によって、熱が前記拡大された前記長尺体同士の隙間を通り、一方の空間から他方の空間へ伝わりやすくなる。よって、他方の空間の温度が上昇して、延焼が早くなる。 Therefore, when a fire occurs in one of the plurality of spaces partitioned by the fire protection compartment, the covering material expands in the out-diameter direction due to heat, and the gap between the plurality of elongated bodies expands. Then, due to the pressure difference and the temperature difference due to the fire, heat is easily transferred from one space to the other through the enlarged gap between the elongated bodies. Therefore, the temperature of the other space rises, and the fire spreads faster.

そこで、本発明は、他方の空間への熱の流出を防止し、延焼を防止できる耐火区画構造及び耐火区画構造の構築方法を提供することを目的とする。 Therefore, an object of the present invention is to provide a fire-resistant compartment structure and a method for constructing a fire-resistant compartment structure that can prevent heat from flowing out to the other space and prevent fire spread.

本発明は、空間を複数に区画する区画体に形成された貫通孔に、長尺体の外周が被覆材によって被覆された複層長尺体を少なくとも一本含む複数の長尺体を挿通した区画貫通構造に設置される耐火区画構造であって、熱により膨張する熱膨張材を含み、貫通孔と複数の長尺体の間の隙間を閉塞するように前記区画貫通構造に取り付けられる防火措置具と、貫通孔の貫通方向における防火措置具よりも一方の空間側の所定領域から他方の空間側の所定領域までの領域で前記複数の長尺体を束状に束縛するように構成される長尺体巻回部と、を備えることを特徴とする耐火区画構造である。 In the present invention, a plurality of long bodies including at least one multi-layered long body whose outer periphery is covered with a covering material are inserted into a through hole formed in a partition body that divides a space into a plurality of sections. A fireproof compartment structure installed in a compartment penetration structure that contains a heat-expanding material and is attached to the compartment penetration structure so as to close the gap between the through hole and a plurality of elongated bodies. It is configured to bind the plurality of elongated bodies in a bundle shape in a region from a predetermined region on one space side to a predetermined region on the other space side of the tool and a fire prevention measure tool in the penetrating direction of the through hole. It is a fireproof compartment structure characterized by having a long body winding portion.

前記耐火区画構造によれば、長尺体巻回部が貫通方向における防火措置具よりも一方の空間側の所定領域から他方の空間側の所定領域までの領域で複数の長尺体を束状に束縛することで、被覆材の径外方向への膨張を規制するから、火災の熱で被覆材が長尺体同士の隙間を塞ぐように膨張する。このため、束状になっている長尺体同士の間の熱の通り道を塞ぐことができる。 According to the fire-resistant compartment structure, the winding portion of the long body bundles a plurality of long bodies in a region from a predetermined region on one space side to a predetermined region on the other space side of the fire protection tool in the penetrating direction. By binding to, the covering material is restricted from expanding in the out-of-diameter direction, so that the covering material expands so as to close the gap between the long bodies due to the heat of the fire. Therefore, it is possible to block the heat passage between the elongated bodies in a bundle shape.

また、本発明の耐火区画構造では、前記防火措置具は、貫通孔と複数の長尺体の間の隙間を埋めるように貫通孔に挿入され、前記長尺体巻回部は、前記貫通方向において、前記熱膨張材よりも一方及び/又は他方の空間側に配置されるように構成することもできる。 Further, in the fireproof compartment structure of the present invention, the fireproof measure tool is inserted into the through hole so as to fill the gap between the through hole and the plurality of long bodies, and the long body winding portion is inserted in the through hole in the through direction. In, it may be configured to be arranged on one and / or the other space side of the thermal expansion material.

上記耐火区画構造によれば、前記長尺体巻回部が貫通方向において、熱膨張材よりも一方及び/又は他方の空間側に配置されるため、熱膨張材の膨張が長尺体巻回部により阻害されることを防止できる。 According to the fireproof compartment structure, since the long body winding portion is arranged on one and / or the other space side of the heat expansion material in the penetrating direction, the expansion of the heat expansion material is caused by the long body winding. It can be prevented from being hindered by the part.

また、本発明の耐火区画構造では、前記防火措置具は、前記複数の長尺体のうち隣り合う長尺体の外周同士で形成される凹部を埋める隙間閉塞部を備え、前記隙間閉塞部は、前記貫通方向において、前記熱膨張材より一方及び/又は他方の空間側に配置され、前記長尺体巻回部は、前記貫通方向において、前記防火措置具より一方及び/又は他方の空間側に配置されるように構成することもできる。 Further, in the fireproof compartment structure of the present invention, the fire prevention measure tool includes a gap closing portion for filling a recess formed between the outer circumferences of adjacent long bodies among the plurality of long bodies, and the gap closing portion is provided. , The long body winding portion is arranged on one and / or the other space side of the thermal expansion material in the penetration direction, and the long body winding portion is located on one and / or the other space side of the fire protection device in the penetration direction. It can also be configured to be placed in.

上記耐火区画構造によれば、熱膨張材の膨張を阻害しないようにしつつ、長尺体巻回部で複数の長尺体を束状にし、しかも、前記隙間閉塞部で凹部を埋めることで、より確実に熱が通る隙間を塞ぐことができる。 According to the above-mentioned fire-resistant partition structure, a plurality of long bodies are bundled at the long body winding portion while the expansion of the thermal expansion material is not hindered, and the recess is filled with the gap closing portion. It is possible to close the gap through which heat passes more reliably.

また、本発明は、空間を複数に区画する区画体に形成された貫通孔に、長尺体の外周が被覆材によって被覆された複層長尺体を少なくとも一本含む複数の長尺体を挿通した区画貫通構造に設置される耐火区画構造の構築方法であって、前記耐火区画構造は、熱により膨張する熱膨張材を含む防火措置具と、前記複数の長尺体を束状に束縛するように構成される長尺体巻回部と、を備え、前記防火措置具を、貫通孔と複数の長尺体の間の隙間を閉塞するように前記区画貫通構造に取り付ける防火措置具配置工程と、前記長尺体巻回部を用いて、貫通孔の貫通方向における防火措置具よりも一方の空間側の所定領域から他方の空間側の所定領域までの領域で複数の長尺体を束状に束縛する長尺体巻回工程と、を備えることを特徴とする耐火区画構造の構築方法である。 Further, in the present invention, a plurality of long bodies including at least one multi-layered long body in which the outer periphery of the long body is covered with a covering material are provided in the through holes formed in the partition body that divides the space into a plurality of spaces. It is a method of constructing a fire-resistant compartment structure installed in an inserted compartment-penetrating structure, in which the fire-resistant compartment structure binds a fire-prevention measure tool including a heat-expanding material that expands by heat and a plurality of long bodies in a bundle. A fire protection tool arrangement comprising a long body winding portion configured to provide the fire protection tool to the compartment penetrating structure so as to close the gap between the through hole and the plurality of long bodies.

It is a method of constructing a fireproof compartment structure, which comprises a long body winding step of binding in a bundle shape.

前記耐火区画構造の構築方法によれば、長尺体巻回部が貫通方向における防火措置具よりも一方の空間側の所定領域から他方の空間側の所定領域までの領域で複数の長尺体を束状に束縛することで、被覆材の径外方向への膨張を規制するから、火災の熱で被覆材が長尺体同士の隙間を塞ぐように膨張する。このため、束状になっている長尺体同士の間の熱の通り道を塞ぐことができる。 According to the method for constructing the fire-resistant compartment structure, a plurality of long bodies are formed in a region where the winding portion of the long body is from a predetermined area on one space side to a predetermined area on the other space side of the fire protection measure tool in the penetrating direction. By binding the covering material in a bundle shape, the expansion of the covering material in the out-of-diameter direction is restricted, so that the covering material expands so as to close the gap between the long bodies due to the heat of the fire. Therefore, it is possible to block the heat passage between the elongated bodies in a bundle shape.

また、本発明の耐火区画構造の構築方法では、前記防火措置具配置工程において、前記防火措置具は、貫通孔と複数の長尺体の間の隙間に埋めるように貫通孔に挿入され、前記長尺体巻回工程では、前記貫通方向において、前記熱膨張材よりも一方及び/又は他方の空間側に長尺体巻回部を配置するように構成することもできる。 Further, in the method for constructing a fireproof compartment structure of the present invention, in the fireproofing tool arranging step, the fireproofing tool is inserted into the through hole so as to fill a gap between the through hole and a plurality of elongated bodies, and the above-mentioned fireproof measures tool is inserted into the through hole.

上記耐火区画構造の構築方法によれば、前記長尺体巻回部が貫通方向において、熱膨張材よりも一方及び/又は他方の空間側に配置されるため、熱膨張材の膨張が長尺体巻回部により阻害されることを防止できる。 According to the method for constructing the fireproof compartment structure, since the long body winding portion is arranged on one and / or the other space side of the thermal expansion material in the penetrating direction, the expansion of the thermal expansion material is long. It can be prevented from being hindered by the body winding part.

また、本発明の耐火区画構造の構築方法では、前記防火措置具は、前記複数の長尺体のうち隣り合う長尺体の外周同士で形成される凹部を埋める隙間閉塞部を備え、前記隙間閉塞部は、貫通方向において、前記熱膨張材よりも一方及び/又は他方の空間側に配置され、前記長尺体巻回工程では、前記貫通方向において、前記長尺体巻回部を前記防火措置具よりも一方及び/又は他方の空間側で前記複数の長尺体に束縛するように構成することもできる。 Further, in the method for constructing the fireproof compartment structure of the present invention, the fireproof measure tool includes a gap closing portion for filling a recess formed between the outer circumferences of adjacent long bodies among the plurality of long bodies, and the gap is provided.

以下、本発明につき、一実施形態を取り上げて説明する。図1は、本実施形態の耐火区画構造1を示す。本実施形態の耐火区画構造1は、建築物内の空間を複数の空間に区画する区画体20に形成した貫通孔200に、被覆材212によって配管213の外周が被覆された被覆配管211を少なくとも一本含む複数の長尺体21を挿通した区画貫通構造2に設置される。なお、以下において、便宜的に、区画体20により区画された空間のうち、図1の左側に示す空間を「一方の空間」と称し、図1の右側に示す空間を「他方の空間」と称して説明する。 Hereinafter, the present invention will be described by taking up one embodiment. FIG. 1 shows a fireproof compartment structure 1 of the present embodiment. In the fireproof partition structure 1 of the present embodiment, at least a coated pipe 211 in which the outer periphery of the pipe 213 is covered with a covering material 212 is provided in a through hole 200 formed in a compartment 20 that divides the space in the building into a plurality of spaces. It is installed in the section penetrating structure 2 through which a plurality of long bodies 21 including one are inserted. In the following, for convenience, the space shown on the left side of FIG. 1 is referred to as "one space", and the space shown on the right side of FIG. 1 is referred to as "the other space" among the spaces partitioned by the compartment 20. I will explain it by calling it.

本実施形態において、区画貫通構造2は、区画体20の厚み方向に貫通するように形成された貫通孔200に、複数の長尺体21を挿通して構成される。本実施形態の区画体20は、建物内の空間を一方の空間と他方の空間に区画する壁である。前記区画体20は、建物内において鉛直方向に沿うように立設され、空間を水平方向で複数(本実施形態では2つ)に区画する。壁としての区画体20は、鉄筋コンクリートなどで形成された中実壁や中空壁が該当する。本実施形態では、区画体20が中実壁であることを前提として説明を行う。 In the present embodiment, the compartment penetrating structure 2 is configured by inserting a plurality of long bodies 21 into through holes 200 formed so as to penetrate the compartment 20 in the thickness direction. The compartment 20 of the present embodiment is a wall that divides the space in the building into one space and the other space. The compartment 20 is erected in the building along the vertical direction, and the space is divided into a plurality of spaces (two in the present embodiment) in the horizontal direction. The compartment 20 as a wall corresponds to a solid wall or a hollow wall formed of reinforced concrete or the like. In the present embodiment, the description will be made on the premise that the compartment 20 is a solid wall.

本実施形態では、区画体20には、一方から他方へ向けて丸く貫通した貫通孔200が形成されている。本実施形態の貫通孔200は、区画体20の厚み方向に真っすぐに伸び、区画体20によって区画された一方の空間と他方の空間を貫通するように形成されている。そして、貫通孔200には、前記被覆配管211を二本含んだ複数(本実施形態では四本)の長尺体21が挿通され、前記複数の長尺体21は、区画体20により区画された一方の空間と他方の空間にまたがって延びる。 In the present embodiment, the compartment 20 is formed with a through hole 200 that penetrates roundly from one side to the other side. The through hole 200 of the present embodiment extends straight in the thickness direction of the compartment 20 and is formed so as to penetrate one space and the other space partitioned by the compartment 20. A plurality of (four in this embodiment) long bodies 21 including two covered pipes 211 are inserted into the through holes 200, and the plurality of long bodies 21 are partitioned by the partition body 20. It extends across one space and the other.

被覆配管211は、長尺体21としての配管213と、該配管213の外周を被覆する被覆材212から構成される。前記配管213は、例えば冷媒などの流体(気体や液体)を流す銅管である。また、被覆材212は、配管213を保護したり、保温、遮音したりする性質を有し、さらに、熱により膨張する性質を有する樹脂発泡体である。前記被覆材212としては、例えば、内部に冷媒を通す配管の外周を覆い、配管を保温する保温材が該当する。本実施形態の被覆材212は、熱により膨張して体積が増加するポリエチレンフォームからなる樹脂発泡体である。 The coated pipe 211 is composed of a pipe 213 as a long body 21 and a covering material 212 that covers the outer periphery of the pipe 213. The pipe 213 is a copper pipe through which a fluid (gas or liquid) such as a refrigerant flows. Further, the covering material 212 is a resin foam having a property of protecting the pipe 213, retaining heat, and insulating sound, and further having a property of expanding due to heat. The covering material 212 corresponds to, for example, a heat insulating material that covers the outer periphery of a pipe through which a refrigerant is passed and keeps the pipe warm. The covering material 212 of the present embodiment is a resin foam made of polyethylene foam that expands due to heat and increases in volume.

本実施形態では、前記被覆配管211以外の長尺体21として、電気配線21と電気配線より大きい塩化ビニル管21が貫通孔200を挿通している。さらに、本実施形態では、各長尺体21は円筒状に形成され、各長尺体21同士の外周面が接触した状態で、複数の長尺体21が貫通孔200に挿入されている。そのため、隣接する長尺体21の外周同士の間には、隙間空間210が形成されている。この隙間空間210は、複数の長尺体21の略中央に形成された中心凹部210aと、複数の長尺体21の外周に形成される凹部210bと、から構成される。 In the present embodiment, as the long body 21 other than the coated pipe 211, the electric wiring 21 and the vinyl chloride pipe 21 larger than the electric wiring insert the through hole 200. Further, in the present embodiment, each long body 21 is formed in a cylindrical shape, and a plurality of long bodies 21 are inserted into the through holes 200 in a state where the outer peripheral surfaces of the long bodies 21 are in contact with each other. Therefore, a gap space 210 is formed between the outer circumferences of the adjacent long bodies 21. The gap space 210 is composed of a central recess 210a formed in the substantially center of the plurality of elongated bodies 21 and a recess 210b formed on the outer periphery of the plurality of elongated bodies 21.

耐火区画構造1は、図1に示すように、前記区画貫通構造2に設置される。前記耐火区画構造1は、区画貫通構造2に取り付けられる防火措置具10と、複数の長尺体21を帯状に巻回するように構成される長尺体巻回部11を備える。また、本実施形態の防火措置具10は、図1に示すように、複数の長尺体21に巻き付けられた状態で、貫通孔200内に挿入されている。そして、前記防火措置具10は、貫通孔200の全域にわたって配置されている。さらに、本実施形態の防火措置具10は、保持部材100と、遮塞体101と、熱膨張材103と、を備える。 As shown in FIG. 1, the fireproof compartment structure 1 is installed in the compartment penetration structure 2. The fireproof compartment structure 1 includes a fire protection tool 10 attached to the compartment penetration structure 2 and a long body winding portion 11 configured to wind a plurality of long bodies 21 in a band shape. Further, as shown in FIG. 1, the fire protection tool 10 of the present embodiment is inserted into the through hole 200 in a state of being wound around a plurality of long bodies 21. The fire protection tool 10 is arranged over the entire area of the through hole 200. Further, the fire protection tool 10 of the present embodiment includes a holding member 100, a blocking body 101, and a thermal expansion material 103.

図2は、区画貫通構造2に取り付ける前の防火措置具10を示す。この防火措置具10は、貫通孔200の全周に亘り、かつ、貫通方向の全域に亘るように円筒状に形成され、内部に複数の長尺体が挿通されるように構成される。この防火措置具10では、熱膨張材103が保持部材100の内周面に沿うように内巻きに配置されている。また、熱膨張材103は、保持部材100のフランジ部1001より軸方向に突出している。そして、フランジ部1001の底面に沿って、保持部材100の周方向に配置された遮塞体101では、図2に示すように、径方向に延びる隙間閉塞部101eが熱膨張材103の外周面に沿って折り曲げられ、フランジ部1001より軸方向に突出している。すなわち、本実施形態の防火措置具10は、区画貫通構造2に取り付ける前の状態において、保持部材100のフランジ部1001より軸方向に熱膨張材103と遮塞体101が突出しており、径外側から径内側に向かってフランジ部1001(保持部材100)、遮塞体101、熱膨張材103の順に配置されている。 FIG. 2 shows a fire protection tool 10 before being attached to the compartment penetration structure 2. The fire protection tool 10 is formed in a cylindrical shape over the entire circumference of the through hole 200 and over the entire circumference in the penetration direction, and is configured such that a plurality of elongated bodies are inserted therein. In the fire protection tool 10, the thermal expansion member 103 is arranged inwardly wound along the inner peripheral surface of the holding member 100. Further, the thermal expansion material 103 protrudes in the axial direction from the flange portion 1001 of the holding member 100. Then, in the blocking body 101 arranged in the circumferential direction of the holding member 100 along the bottom surface of the flange portion 1001, as shown in FIG. 2, the gap closing portion 101e extending in the radial direction is the outer peripheral surface of the thermal expansion material 103.

袋1030は、耐火材1031を収納した状態で、周縁部を封止している。本実施形態の袋1030は長方形状に形成されており、長辺が保持部材100の内周よりも長く形成されている。また、袋1030の短辺は、保持部材100の軸方向の長さより長い。さらに、封止した周縁部の長辺には、所定間隔ごとに挿通孔103aが形成されている。具体的には、本実施形態の袋1030では、三つの挿通孔103aが形成され、これらの挿通孔103aは、長方形状の袋1030の一方の短辺近傍で間隔をあけて配置される。本実施形態において、前記間隔は、スリーブ本体部1000の熱膨張材取付部1000c同士の間隔と同一である。そのため、熱膨張材103を保持部材100に固定させる際には、前記挿通孔103aと熱膨張材取付部1000cを利用して取り付ける。具体的には、前記挿通孔103aが形成された長辺を袋1030内面に向かって折り曲げた後、前記一方の短辺をスリーブ本体部1000の周方向の端部1000eに合わせ、挿通孔103aに係止爪1000cbを挿通させながら、熱膨張材103をスリーブ本体部1000の内周面に沿わせて配置し、係止部1000caを係止爪1000cb側に屈曲させ、係止部1000caの孔に係止爪1000cbを係合させることで取り付けを行う。 The bag 1030 has a peripheral portion sealed with the refractory material 1031 housed therein. The bag 1030 of the present embodiment is formed in a rectangular shape, and the long side is formed longer than the inner circumference of the holding member 100. Further, the short side of the bag 1030 is longer than the axial length of the holding member 100. Further, insertion holes 103a are formed at predetermined intervals on the long side of the sealed peripheral edge portion. Specifically, in the bag 1030 of the present embodiment, three insertion holes 103a are formed, and these insertion holes 103a are arranged at intervals near one short side of the rectangular bag 1030. In the present embodiment, the interval is the same as the interval between the thermal expansion material mounting portions 1000c of the sleeve main body portion 1000. Therefore, when fixing the thermal expansion material 103 to the holding member 100, the insertion hole 103a and the thermal expansion material mounting portion 1000c are used for mounting. Specifically, after the long side on which the insertion hole 103a is formed is bent toward the inner surface of the bag 1030, one of the short sides is aligned with the circumferential end portion 1000e of the sleeve body portion 1000 to form the insertion hole 103a. The thermal expansion material 103 is arranged along the inner peripheral surface of the sleeve main body 1000 while the locking claw 1000cc is inserted, and the locking portion 1000ca is bent toward the locking claw 1000cc to fill the hole of the locking portion 1000ca. It is attached by engaging the locking claw 1000cc.

本実施形態の長尺体巻回部11は、図1に示すように、貫通孔200の貫通方向における防火措置具10より一方の空間側に配置され、複数の長尺体21の外周を巻回している。前記長尺体巻回部11は帯状に形成され、複数の長尺体21の外周に巻回するべく、複数の長尺体21の外周より長く形成されている。また、本実施形態の長尺体巻回部11には、複数の長尺体21の外周面に接触する側の面の短辺に粘着性部材が塗布されている。そのため、長尺体巻回部11を複数の長尺体21に巻回した際に、粘着性部材で長尺体巻回部11を複数の長尺体21の外周に固定させることができる。なお、粘着性部材は、複数の長尺体21の外周面に接触する側の面の全域に設けることもできるし、一部に設けることもできる。 As shown in FIG. 1, the long body winding portion 11 of the present embodiment is arranged on one space side of the fire prevention measure tool 10 in the penetration direction of the through hole 200, and winds the outer periphery of the plurality of long bodies 21. I'm turning. The long body winding portion 11 is formed in a band shape, and is formed longer than the outer periphery of the plurality of long bodies 21 so as to be wound around the outer periphery of the plurality of long bodies 21. Further, the long body winding portion 11 of the present embodiment is coated with an adhesive member on the short side of the surface of the plurality of long bodies 21 on the side in contact with the outer peripheral surface. Therefore, when the long body winding portion 11 is wound around the plurality of long bodies 21, the long body winding portion 11 can be fixed to the outer periphery of the plurality of long bodies 21 with an adhesive member. The adhesive member may be provided on the entire surface of the surface of the plurality of long bodies 21 on the side in contact with the outer peripheral surface, or may be provided on a part of the surface.

以上が、本実施形態の耐火区画構造1についての説明である。続いて、本実施形態の耐火区画構造1の構築方法について説明する。本実施形態の耐火区画構造1を構築する場合、防火措置具配置工程と、長尺体巻回工程と、を行う必要がある。 The above is the description of the fireproof section structure 1 of the present embodiment. Subsequently, a method of constructing the fireproof compartment structure 1 of the present embodiment will be described. When constructing the fireproof compartment structure 1 of the present embodiment, it is necessary to perform a fire protection measure arrangement step and a long body winding step.

図5は、防火措置具配置工程の挿入工程を示す。この挿入工程では、一方の空間において、貫通孔200を通って複数の空間に延びる複数の長尺体21の外周に、防火措置具10を取り付けた後、該防火措置具10を貫通孔200に挿入する。この際、スリーブ本体部1000の周方向の端部1000e同士を拡開させるとともに、熱膨張材103の周方向の両端部が重なった状態を解消させる。これにより、周方向の端部1000eの間に配置されている遮塞体101の分断線部101cが周方向に拡開し、図5において二点鎖線で示すように、複数の長尺体21の外周に防火措置具10を取り付けることができる。ここで、本実施形態においては、図5に示すように、遮塞体101はフランジ部1001の底面と離れて配置されている。なお、本実施形態では、一方の空間において、スリーブ本体部1000のフランジ部1001が形成されている端部とは逆の端部が貫通孔200側に位置するように、防火措置具10を配置する。 FIG. 5 shows an insertion process of the fire protection tool placement process. In this insertion step, after attaching the fire protection tool 10 to the outer periphery of the plurality of long bodies 21 extending to the plurality of spaces through the through hole 200 in one space, the fire protection tool 10 is inserted into the through hole 200. insert. At this time, the peripheral end portions 1000e of the sleeve main body portion 1000 are expanded to each other, and the state in which both end portions of the thermal expansion material 103 in the circumferential direction are overlapped is eliminated. As a result, the dividing line portion 101c of the blocking body 101 arranged between the peripheral ends 1000e expands in the circumferential direction, and as shown by the two-dot chain line in FIG. 5, a plurality of long bodies 21 A fire protection tool 10 can be attached to the outer periphery of the. Here, in the present embodiment, as shown in FIG. 5, the blocking body 101 is arranged apart from the bottom surface of the flange portion 1001. In this embodiment, the fire protection tool 10 is arranged so that the end opposite to the end where the flange portion 1001 of the sleeve main body 1000 is formed is located on the through hole 200 side in one space. do.

防火措置具10を複数の長尺体21の外周に沿って取り付けた後は、防火措置具10を他方の空間側に向かって、長尺体21に沿うようにスライドさせ、フランジ部1001の底面と重なる遮塞体101が区画体20の外面に当接するまで、防火措置具10を貫通孔200に押し込む。遮塞体101が区画体20の外面に当接した後、フランジ部1001を貫通孔200の方向に動かすことで、フランジ部1001と遮塞体101との間隔が埋まるとともに、区画体20の外面とフランジ部1001の底面とにより遮塞体101が挟まれる。その後、ビス止め部101f及びビス止め孔1001a(図5において図示しない)にビスを挿入し、防火措置具10を区画体20に固定させる。 After the fire protection tool 10 is attached along the outer periphery of the plurality of long bodies 21, the fire protection tool 10 is slid toward the other space side along the long body 21 and the bottom surface of the flange portion 1001. The fire protection tool 10 is pushed into the through hole 200 until the blocking body 101 overlapping with the above comes into contact with the outer surface of the partition body 20. After the blocking body 101 comes into contact with the outer surface of the partition body 20, by moving the flange portion 1001 in the direction of the through hole 200, the distance between the flange portion 1001 and the blocking body 101 is filled, and the outer surface of the partition body 20 is filled. The blocking body 101 is sandwiched between the and the bottom surface of the flange portion 1001. After that, a screw is inserted into the screw fixing portion 101f and the screw fixing hole 1001a (not shown in FIG. 5), and the fire protection tool 10 is fixed to the partition body 20.

図6は、防火措置具配置工程の熱膨張材押込工程を示す。この熱膨張材押込工程では、保持部材100の軸方向の長さよりに長く、フランジ部1001から軸方向に突出している熱膨張材103を貫通孔200の方向に折り曲げて、貫通孔200に押し込む。この際、図6において二点鎖線で示す熱膨張材103を、図6の矢印で示すように長尺体21側に折り曲げる。そして、熱膨張材103と複数の長尺体21との間の隙間を埋めるようにして、熱膨張材103を貫通孔200内に押し込む。また、図6に示すように、熱膨張材103を貫通孔200に押し込む際は、熱膨張材103が遮塞体101よりも貫通孔200側に配置されるように押し込む。これにより、熱膨張材103を貫通孔200内に収納することができる。また、前記熱膨張材103を貫通孔200に収納することで、熱膨張材103の外周面に沿って折り曲げられていた隙間閉塞部101eが、長尺体21の外周に沿うこととなる。 FIG. 6 shows a thermal expansion material pushing process in the process of arranging the fire protection measures. In this thermal expansion material pushing step, the thermal expansion material 103, which is longer than the axial length of the holding member 100 and protrudes axially from the flange portion 1001, is bent in the direction of the through hole 200 and pushed into the through hole 200. At this time, the thermal expansion material 103 shown by the alternate long and short dash line in FIG. 6 is bent toward the elongated body 21 as shown by the arrow in FIG. Then, the thermal expansion material 103 is pushed into the through hole 200 so as to fill the gap between the thermal expansion material 103 and the plurality of long bodies 21. Further, as shown in FIG. 6, when the thermal expansion material 103 is pushed into the through hole 200, the thermal expansion material 103 is pushed so as to be arranged on the through hole 200 side of the blocking body 101. As a result, the thermal expansion material 103 can be housed in the through hole 200. Further, by storing the thermal expansion material 103 in the through hole 200, the gap closing portion 101e bent along the outer peripheral surface of the thermal expansion material 103 becomes along the outer periphery of the long body 21.

図7は、防火措置具配置工程の隙間閉塞部押込工程を示す。この隙間閉塞部押込工程では、複数の長尺体21の外周に沿うように突出している隙間閉塞部101eを貫通孔200に押し込む。ここで、本実施形態の複数の長尺体21は、長尺体21同士の外周面が接触した状態で、貫通孔200に挿入されている。そのため、図9に示すように、長尺体21同士の間には隙間空間210として凹部210bが形成されている。そこで、隙間閉塞部押込工程では、凹部210bを埋めるように、隙間閉塞部101eを貫通孔200に押し込む。具体的には、隙間閉塞部101eを貫通孔200内の方に折り曲げた後、フランジ部1001側に折り返し、再度、隙間閉塞部101eを貫通孔200内の方に折り曲げ、熱膨張材103と長尺体21との間に押し込んで、貫通孔200に挿入する。ここで、本実施形態では、隙間閉塞部101eが大隙間閉塞部101eaと小隙間閉塞部101ebを備えるところ、大隙間閉塞部101eaで凹部210bが大きく閉塞され、小隙間閉塞部101ebで大隙間閉塞部101eaによって閉塞しきれない凹部210bを閉塞する。そして、図7に示すように、熱膨張材103よりも複数の長尺体21側に隙間閉塞部101eが配置される。以上が、防火措置具配置工程の説明である。続いて、長尺体巻回工程について説明する。 FIG. 7 shows a gap closing portion pushing process in the process of arranging the fire protection measures. In this gap closing portion pushing step, the gap closing portion 101e projecting along the outer periphery of the plurality of long bodies 21 is pushed into the through hole 200. Here, the plurality of long bodies 21 of the present embodiment are inserted into the through holes 200 in a state where the outer peripheral surfaces of the long bodies 21 are in contact with each other. Therefore, as shown in FIG. 9, a recess 210b is formed as a gap space 210 between the long bodies 21. Therefore, in the gap closing portion pushing step, the gap closing portion 101e is pushed into the through hole 200 so as to fill the recess 210b. Specifically, after the gap closing portion 101e is bent toward the inside of the through hole 200, the gap closing portion 101e is folded back toward the flange portion 1001 and the gap closing portion 101e is bent again toward the inside of the through hole 200. It is pushed between the scale body 21 and inserted into the through hole 200. Here, in the present embodiment, where the gap closing portion 101e includes the large gap closing portion 101ea and the small gap closing portion 101eb, the recess 210b is largely closed by the large gap closing portion 101ea, and the large gap closing portion 101eb is closed by the small gap closing portion 101eb. The recess 210b that cannot be completely closed by the portion 101ea is closed. Then, as shown in FIG. 7, the gap closing portion 101e is arranged on the side of the plurality of long bodies 21 with respect to the thermal expansion material 103. The above is the explanation of the process of arranging the fire protection equipment. Subsequently, the long body winding process will be described.

長尺体巻回工程では、長尺体巻回部11を用いて、貫通孔200の貫通方向における防火措置具10よりも一方の空間から他方の空間までの領域で複数の長尺体21を束状に束縛する。本実施形態では、防火措置具配置工程の後、防火措置具10より一方の空間側で、複数の長尺体21に長尺体巻回部11を配置し、図8に示すように、貫通孔200に挿入された防火措置具10のフランジ部1001の近傍で、複数の長尺体21に長尺体巻回部11を巻回する。また、本実施形態の長尺体巻回部11は、複数の長尺体21の外周面に接触する側の面の短辺に粘着性部材が設けられているため、長尺体巻回部11を巻回する場合は、長尺体巻回部11の粘着性部材を用いて、長尺体21の外周面に、長尺体巻回部11の一方の短辺を貼付け、長尺体巻回部11を複数の長尺体21の外周に沿って巻き付けた後、他方の短辺の粘着性部材を長尺体巻回部11の外面に貼付け、図9に示すように、長尺体巻回部11を複数の長尺体21に固定させた状態にする。なお、長尺体巻回部11による長尺体21の束縛は、火災の熱により、被覆配管211の被覆材212が束縛部分で膨張しないような適度な締め付けとなる。このようにして、図1に示す耐火区画構造1を形成する。 In the long body winding step, the long body winding portion 11 is used to form a plurality of long bodies 21 in a region from one space to the other space rather than the fire prevention measure tool 10 in the penetration direction of the through hole 200. Bind in a bundle. In the present embodiment, after the fire protection tool arranging step, the long body winding portion 11 is arranged on a plurality of long bodies 21 on one space side of the fire protection tool 10, and penetrates as shown in FIG. In the vicinity of the flange portion 1001 of the fire protection tool 10 inserted into the hole 200, the long body winding portion 11 is wound around a plurality of long bodies 21. Further, since the long body winding portion 11 of the present embodiment is provided with an adhesive member on the short side of the surface of the plurality of long bodies 21 on the side in contact with the outer peripheral surface, the long body winding portion 11 is provided. When winding 11, the adhesive member of the long body winding portion 11 is used, and one short side of the long body winding portion 11 is attached to the outer peripheral surface of the long body 21 to attach the long body. After winding the winding portion 11 along the outer circumference of the plurality of long bodies 21, the adhesive member on the other short side is attached to the outer surface of the long body winding portion 11 and is long as shown in FIG. The body winding portion 11 is fixed to a plurality of long bodies 21. The binding of the long body 21 by the long body winding portion 11 is an appropriate tightening so that the covering material 212 of the covering pipe 211 does not expand at the binding portion due to the heat of the fire. In this way, the fireproof compartment structure 1 shown in FIG. 1 is formed.

以上、本実施形態の耐火区画構造1及びその構築方法によれば、貫通方向において、長尺体巻回部11が防火措置具10よりも一方の空間側の所定領域から他方の空間側の所定領域までの領域で複数の長尺体21を束状に束縛することで、被覆材212の径外方向への膨張を規制するから、火災の熱で被覆材212が長尺体21同士の隙間を塞ぐように膨張する。このため、束状になっている長尺体21同士の間の熱の通り道を塞ぐことができる。なお、ここでいう「所定領域」とは、長尺体巻回部が長尺体を巻回する範囲として想定された領域のことをいい、例えば、区画体20から100mm程度離れた範囲内の領域である。具体的に、本実施形態では、長尺体巻回部11が一方の空間で、かつ、貫通孔200に挿入される防火措置具10の近くで複数の長尺体21に巻回されている。そのため、他方の空間で火災が発生した場合には、他方の空間から貫通孔200を通って一方の空間に流れてくる熱により膨張する被覆材212を、図9に示す隙間空間210(凹部210b、中心凹部210a)が塞がるように膨張させる。これにより、熱の通り道を塞ぐことができる。また、本実施形態では、複数の長尺体21が長尺体巻回部11により巻回されることで、被覆材212が複数の長尺体21を径外方向に膨張させることが規制されているため、被覆材212は複数の長尺体21の径内方向に膨張され、結果として、隙間空間210が埋まり、隣の空間へ熱が流れることを防止できる。 As described above, according to the fire-resistant compartment structure 1 and the construction method thereof of the present embodiment, in the penetrating direction, the long body winding portion 11 is designated from a predetermined region on one space side to a predetermined region on the other space side of the fire protection measure tool 10. By binding a plurality of long bodies 21 in a bundle shape in the area up to the area, the expansion of the covering material 212 in the out-of-diameter direction is restricted, so that the covering material 212 has a gap between the long bodies 21 due to the heat of the fire. Inflate to block. Therefore, it is possible to block the heat passage between the elongated bodies 21 that are bundled together. The "predetermined area" here means an area assumed as a range in which the long body winding portion winds the long body, and is, for example, within a range about 100 mm away from the compartment 20. It is an area. Specifically, in the present embodiment, the long body winding portion 11 is wound around a plurality of long bodies 21 in one space and near the fire protection tool 10 inserted into the through hole 200. .. Therefore, when a fire breaks out in the other space, the covering material 212 that expands due to the heat flowing from the other space through the through hole 200 to the one space is replaced with the gap space 210 (recessed portion 210b) shown in FIG. , The central recess 210a) is expanded so as to be closed. This can block the heat path. Further, in the present embodiment, the covering material 212 is restricted from expanding the plurality of long bodies 21 in the out-of-diameter direction by winding the plurality of long bodies 21 by the long body winding portion 11. Therefore, the covering material 212 is expanded in the radial direction of the plurality of long bodies 21, and as a result, the gap space 210 is filled and heat can be prevented from flowing to the adjacent space.

また、上記耐火区画構造1によれば、前記長尺体巻回部11が熱膨張材103より一方の空間側に配置されるため、熱膨張材103の膨張が長尺体巻回部11により阻害されることを防止できる。具体的には、貫通孔200の貫通孔方向における一方の空間に長尺体巻回部11が配置されているため、火災の熱で貫通孔200内の熱膨張材103が膨張するときは長尺体巻回部11を長尺体21に巻回しているか否かにかかわらず、熱膨張材103が貫通孔200を埋めることができる。 Further, according to the fireproof partition structure 1, since the long body winding portion 11 is arranged on one space side of the thermal expansion material 103, the expansion of the thermal expansion material 103 is caused by the long body winding portion 11. It can be prevented from being hindered. Specifically, since the long body winding portion 11 is arranged in one space in the through hole direction of the through hole 200, it is long when the thermal expansion material 103 in the through hole 200 expands due to the heat of the fire. The thermal expansion material 103 can fill the through hole 200 regardless of whether or not the scale winding portion 11 is wound around the long body 21.

また、本実施形態の遮塞体101は、防火措置具10の一方の空間側に配置されているため、防火措置具10の開口から一方又は他方の空間への熱の流出を防止できる。具体的には、遮塞体101はフランジ部1001の底面と重なるように配置されているため、防火措置具10の開口から一方又は他方の空間への熱の流出を防止できる。 Further, since the blocking body 101 of the present embodiment is arranged on one space side of the fire protection tool 10, it is possible to prevent heat from flowing out from the opening of the fire protection tool 10 to one or the other space. Specifically, since the blocking body 101 is arranged so as to overlap the bottom surface of the flange portion 1001, it is possible to prevent heat from flowing out from the opening of the fire protection tool 10 to one or the other space.

また、本実施形態の耐火区画構造1では、凹部210bを埋めるように、隙間閉塞部101eが貫通孔200に挿入されている。そのため、貫通孔200内における長尺体21同士の隙間(凹部210b)を塞ぐことができる。したがって、一方の空間への延焼を防止できる。 Further, in the fireproof partition structure 1 of the present embodiment, the gap closing portion 101e is inserted into the through hole 200 so as to fill the recess 210b. Therefore, it is possible to close the gap (recessed portion 210b) between the long bodies 21 in the through hole 200. Therefore, it is possible to prevent the spread of fire to one space.

また、本実施形態では、フランジ部1001の底面と重なる遮塞体101が区画体20の外面に当たるまで、防火措置具10が貫通孔200に押し込まれているとともに、フランジ部1001の底面と区画体20の外面で遮塞体101が挟まれている。そのため、遮塞体101(隙間閉塞部101e)が一方の空間側に動くことが防止され、確実に長尺体21同士の隙間空間210を塞いだ状態を維持できる。 Further, in the present embodiment, the fire protection tool 10 is pushed into the through hole 200 until the blocking body 101 overlapping the bottom surface of the flange portion 1001 hits the outer surface of the partition body 20, and the bottom surface of the flange portion 1001 and the partition body are formed. The obstruction body 101 is sandwiched between the outer surfaces of 20. Therefore, the blocking body 101 (gap closing portion 101e) is prevented from moving to one space side, and the state in which the gap space 210 between the long bodies 21 is surely closed can be maintained.

また、隙間閉塞部101eは、保持部材100のスリット部1000aにスリット挿入部101gを挿入することで、筒状の保持部材100の周方向に沿って配置される。そのため、遮塞体101が保持部材100に対して周方向に回転することを防止できる。よって、隙間閉塞部101eを長尺体21同士の隙間空間(凹部210b)に挿入した後に、遮塞体101が周方向に回転することで、隙間閉塞部101eが長尺体21の外周面にぶつかって、凹部210bから抜けることを防止できる。 Further, the gap closing portion 101e is arranged along the circumferential direction of the cylindrical holding member 100 by inserting the slit inserting portion 101g into the slit portion 1000a of the holding member 100. Therefore, it is possible to prevent the blocking body 101 from rotating in the circumferential direction with respect to the holding member 100. Therefore, after the gap closing portion 101e is inserted into the gap space (recessed portion 210b) between the long bodies 21, the blocking body 101 rotates in the circumferential direction, so that the gap closing portion 101e is placed on the outer peripheral surface of the long body 21. It is possible to prevent the concave portion 210b from colliding with the concave portion 210b.

また、本実施形態では、遮塞体101の中央から外縁に延びる複数の切込線部101bは、外縁側に近づくにつれて、周方向での距離を大きくする放射状に形成されているため、複数の切込線により規定された隙間閉塞部101eは、遮塞体101の中央位置に近づくにつれて幅狭となるテーパ状になっている。よって、隙間閉塞部101eを凹部210bに挿入させやすい。 Further, in the present embodiment, the plurality of cut line portions 101b extending from the center of the obstruction body 101 to the outer edge are formed in a radial pattern in which the distance in the circumferential direction increases as the distance approaches the outer edge side. The gap closing portion 101e defined by the cut line has a tapered shape that becomes narrower as it approaches the center position of the blocking body 101. Therefore, it is easy to insert the gap closing portion 101e into the recess 210b.

続いて、他の実施形態に係る耐火区画構造1について、図10及び図11を参照しながら説明する。他の実施形態に係る耐火区画構造1において、上述した一の実施形態の構成と同様の構成については、同一の符号を付し、説明は省略する。 Subsequently, the fireproof compartment structure 1 according to another embodiment will be described with reference to FIGS. 10 and 11. In the fireproof compartment structure 1 according to another embodiment, the same components as those of the above-described configuration of one embodiment are designated by the same reference numerals, and the description thereof will be omitted.

他の実施形態の耐火区画構造1は、一の実施形態にて説明した防火措置具10と、長尺体巻回部11に加えて、押さえ部材102を備える。他の実施形態の耐火区画構造1では、図11に示すように、貫通孔200に挿入された防火措置具10の前方に押さえ部材102が取り付けられている。この押さえ部材102は、図10に示すように、円形のシート状に形成され、中心部に形成された略八角形状の補助孔102bを利用して、長尺体21を貫通させている。また、他の実施形態においては、縮径前の保持部材100の外径が貫通孔200の内周より大きく構成されている。そのため、他の実施形態では、防火措置具10を複数の長尺体21の外周に沿って取り付けた後、周方向の端部1000e同士を近づけて、保持部材100の外径を貫通孔200の内周より小さくなるように縮径させてから貫通孔200に挿入し、その後、保持部材100を貫通孔200の内周に沿って拡径させている。よって、他の実施形態の耐火区画構造1では、貫通孔200に挿入された防火措置具10は縮径されている。さらに、他の実施形態の耐火区画構造1では、長尺体巻回部11は、後述する拡開部102fと重なるように配置される。 The fire-resistant compartment structure 1 of another embodiment includes the fire-prevention measure tool 10 described in one embodiment, the long body winding portion 11, and the holding member 102. In the fire-resistant compartment structure 1 of another embodiment, as shown in FIG. 11, a holding member 102 is attached to the front of the fire-prevention measure tool 10 inserted into the through hole 200. As shown in FIG. 10, the pressing member 102 is formed in the shape of a circular sheet, and the elongated body 21 is penetrated by using the substantially octagonal auxiliary hole 102b formed in the central portion. Further, in another embodiment, the outer diameter of the holding member 100 before the diameter reduction is configured to be larger than the inner circumference of the through hole 200. Therefore, in another embodiment, after the fire protection tool 10 is attached along the outer periphery of the plurality of long bodies 21, the peripheral ends 1000e are brought close to each other, and the outer diameter of the holding member 100 is set to the through hole 200. The diameter is reduced to be smaller than the inner circumference and then inserted into the through hole 200, and then the holding member 100 is expanded along the inner circumference of the through hole 200. Therefore, in the fireproof compartment structure 1 of the other embodiment, the diameter of the fire protection tool 10 inserted in the through hole 200 is reduced. Further, in the fireproof compartment structure 1 of another embodiment, the long body winding portion 11 is arranged so as to overlap with the expansion portion 102f described later.

図10は、押さえ部材102の正面図である。本実施形態の押さえ部材102は、八角形の補助孔102bの各角には、外縁側に延びる切込線部102cを備える。また、前記切込線部102cは、後述する分断線部102aより短く形成されているとともに、周方向に延びる二本の周方向切込線部102caも備える。そして、切込線部102c同士、又は切込線部102cと分断線部102aにより拡開部102fが規定される。本実施形態の押さえ部材102では、周方向に合計で8つの切込線部102cと分断線部102aが形成されているため、補助孔102bを中心として全周に拡開部102fが8つ配置されている。そのため、前記拡開部102fを屈曲させることにより、補助孔102bを拡開できる。また、図10に示すように、拡開部102fに周方向切込線部102caが形成されているため、拡開部102fによって屈曲具合を調整できる。そのため、長尺体21の外周に合わせて、補助孔102bの大きさを変化させることができる。さらに、押さえ部材102には、補助孔102bから外縁に延び、押さえ部材102を分断する分断線部102aを備える。この分断線部102aを利用して、円形の押さえ部材102を長尺体21に取り付ける。加えて、本実施形態の押さえ部材102には、ビス止め孔102eが設けられている。このビス止め孔102eを利用して、押さえ部材102を区画体20に固定する。 FIG. 10 is a front view of the pressing member 102. The pressing member 102 of the present embodiment includes a cut line portion 102c extending toward the outer edge side at each corner of the octagonal auxiliary hole 102b. Further, the cut line portion 102c is formed shorter than the cut line portion 102a described later, and also includes two circumferential cut line portions 102ca extending in the circumferential direction. Then, the expansion portion 102f is defined by the cut line portions 102c, or by the cut line portions 102c and the dividing line portion 102a. In the holding member 102 of the present embodiment, a total of eight cut wire portions 102c and a dividing wire portion 102a are formed in the circumferential direction, so that eight expansion portions 102f are arranged around the entire circumference centering on the auxiliary hole 102b. Has been done. Therefore, the auxiliary hole 102b can be expanded by bending the expansion portion 102f. Further, as shown in FIG. 10, since the circumferential cut line portion 102ca is formed in the expansion portion 102f, the bending condition can be adjusted by the expansion portion 102f. Therefore, the size of the auxiliary hole 102b can be changed according to the outer circumference of the long body 21. Further, the pressing member 102 is provided with a dividing wire portion 102a extending from the auxiliary hole 102b to the outer edge and dividing the pressing member 102. Using this dividing wire portion 102a, the circular pressing member 102 is attached to the long body 21. In addition, the pressing member 102 of the present embodiment is provided with a screw fixing hole 102e. The holding member 102 is fixed to the compartment 20 by using the screw fixing hole 102e.

本実施形態の押さえ部材102を耐火区画構造1に取り付ける場合は、防火措置具配置工程と長尺体巻回工程の後、取付けを行う(押さえ取付工程)。なお、他の実施形態では、ビスで防火措置具10を区画体20に対して固定することは、押さえ取付工程にて行う。具体的には、押さえ取付工程では、防火措置具10を貫通孔200に挿入した後、押さえ部材102を周方向に拡開し、分断線部102aから補助孔102bに複数の長尺体21を挿通させる。このとき、複数の長尺体21の径に対応させるべく、拡開部102fを一方の空間側に屈曲させ、補助孔102bを拡開させる。ここで、屈曲させた拡開部102fは、長尺体巻回部11に重なるように配置される。そして、防火措置具10より一方の空間側に押さえ部材102を配置する。さらに、他の実施形態では、ビス止め孔102eが保持部材100のビス止め孔1001a及びビス止め部101f(図示しない)に重なるように配置される。そのため、ビス止め部101f及びビス止め孔1001aを挿通するように、ビス止め孔102eにビス(図示しない)を挿通して、防火措置具10及び押さえ部材102を区画体20に固定させる。 When the holding member 102 of the present embodiment is attached to the fireproof compartment structure 1, it is attached after the fire protection measure arrangement step and the long body winding step (holding attachment step). In another embodiment, fixing the fire protection tool 10 to the compartment 20 with screws is performed in the presser attachment step. Specifically, in the presser attachment step, after the fire protection tool 10 is inserted into the through hole 200, the presser member 102 is expanded in the circumferential direction, and a plurality of long bodies 21 are inserted from the dividing wire portion 102a into the auxiliary hole 102b. Let it be inserted. At this time, in order to correspond to the diameters of the plurality of long bodies 21, the expansion portion 102f is bent toward one space side, and the auxiliary hole 102b is expanded. Here, the bent expansion portion 102f is arranged so as to overlap the long body winding portion 11. Then, the holding member 102 is arranged on one space side of the fire protection tool 10. Further, in another embodiment, the screw fixing hole 102e is arranged so as to overlap the screw fixing hole 1001a and the screw fixing portion 101f (not shown) of the holding member 100. Therefore, a screw (not shown) is inserted through the screw fixing hole 102e so that the screw fixing portion 101f and the screw fixing hole 1001a are inserted, and the fire protection tool 10 and the holding member 102 are fixed to the partition body 20.
