Description
本発明は、スリーブ閉塞装置、スリーブ、ブッシング、スリーブ閉塞構造、及びスリーブ閉塞構造の製造方法に関する。 The present invention relates to sleeve closure devices, sleeves, bushings, sleeve closure structures, and methods of making sleeve closure structures.
例えば、空洞部を有する防火区画壁（中空壁）に配線・配管材を貫通させるため、防火区画壁には厚み方向に貫通する貫通孔が形成されている。この防火区画壁の貫通孔は、当該防火区画壁を厚み方向に貫通するように設置されたスリーブの内側に区画される。スリーブは、防火区画壁の表面から所定長さ突出するように設置される。 For example, in order to allow wiring and piping materials to pass through a fireproof partition wall (hollow wall) having a hollow portion, a through-hole is formed in the fireproof partition wall to penetrate in the thickness direction. The through hole of the fireproof partition wall is defined inside a sleeve installed so as to penetrate the fireproof partition wall in the thickness direction. The sleeve is installed so as to protrude a predetermined length from the surface of the fireproof compartment wall.
また、貫通孔に配線・配管材を貫通させた状態では、配線・配管材の周囲には隙間が形成され、貫通孔に配線・配管材を貫通させていない状態は、貫通孔そのものが開口する。上記隙間や貫通孔そのものが、火災発生時の火炎、煙、有毒ガスの伝搬経路となることを阻止するため、隙間や貫通孔は閉塞シートによって閉塞される。例えば、特許文献１の耐火構造においては、配線・配管材が貫通されていないスリーブに対し、スリーブの開口を覆うように閉塞シートの一例である耐火性シートを装着し、耐火性シートによって貫通孔を閉塞している。 In addition, when the wiring/piping material is passed through the through-hole, a gap is formed around the wiring/piping material, and when the wiring/piping material is not passed through the through-hole, the through-hole itself is open. . In order to prevent the gaps and through-holes themselves from becoming propagation paths for flames, smoke, and toxic gases when a fire breaks out, the gaps and through-holes are closed with a closure sheet. For example, in the fire-resistant structure of Patent Document 1, a fire-resistant sheet, which is an example of a blocking sheet, is attached to a sleeve through which wiring and piping materials do not pass so as to cover the opening of the sleeve, and the through-hole is covered by the fire-resistant sheet. blockage.
ところが、耐火構造には、スリーブにおける防火区画壁からの突出部の外周に対し、定められた規定長さは閉塞シートを重ねて巻き付けることが設計や規格によって定められている場合がある。このような場合、特許文献１の耐火構造においては、スリーブの端から規定長さを計測する作業が必要であり、さらには、スリーブに対し閉塞シートが規定長さ重ねられているかを確認する作業も必要であった。 However, in some fireproof structures, the design or standard may stipulate that the closure sheet should be wrapped around the outer periphery of the protruding portion of the sleeve from the fireproof partition wall for a prescribed length. In such a case, in the fireproof structure of Patent Document 1, it is necessary to measure the specified length from the end of the sleeve, and furthermore, to check whether the closure sheet is overlapped with the sleeve by the specified length. was also necessary.

A first embodiment embodying a sleeve, a sleeve closure device, a sleeve closure structure, and a method of manufacturing the sleeve closure structure will be described below with reference to FIGS. 1 to 5. FIG.
図１に示すように、区画壁としての防火中空壁Ｗは、複数本の軽量形鋼材１０と、軽量形鋼材１０を挟むようにして立設された複数対の間仕切り壁１１とから構築されている。間仕切り壁１１は、例えば石膏ボードが採用される。防火中空壁Ｗには厚さが複数種類設定されている。 As shown in FIG. 1, a fireproof hollow wall W as a partition wall is constructed from a plurality of light-weight shaped steel members 10 and a plurality of pairs of partition walls 11 erected so as to sandwich the light-weight shaped steel members 10. The partition wall 11 employs, for example, a gypsum board. A plurality of thicknesses are set for the fireproof hollow wall W.
軽量形鋼材１０を挟んで相対向する間仕切り壁１１同士の間には空洞部１２が形成されている。防火中空壁Ｗは、軽量形鋼材１０の太さを変更し、防火中空壁Ｗの厚さ方向に沿った空洞部１２の幅を変更することにより、防火中空壁Ｗの厚さが変更されるようになっている。防火中空壁Ｗには、配線・配管材１３を貫通させるための貫通孔１４が、防火中空壁Ｗの厚さ方向に貫通して形成されている。なお、配線・配管材１３とは、建築物内に配設される配線（制御用ケーブル、同軸ケーブル、光ケーブル等）及び配管材（合成樹脂製可撓電線管、鋼製電線管等）の総称のことである。 A hollow portion 12 is formed between the partition walls 11 facing each other with the light-weight shaped steel member 10 interposed therebetween. The thickness of the fire prevention hollow wall W is changed by changing the thickness of the lightweight shaped steel material 10 and changing the width of the hollow portion 12 along the thickness direction of the fire prevention hollow wall W. It's like A through hole 14 is formed in the fire prevention hollow wall W in the thickness direction of the fire prevention hollow wall W so that the wiring/piping member 13 is passed through the through hole 14 .

したがって、スリーブ２０は、防火中空壁Ｗの両方の表面Ｗａから突出させた各突出部２１に規定長さＭを確保できるだけの長さを有している。各突出部２１に規定長さＭを確保するためには、突出部２１の長さは、規定長さＭよりも長くする必要がある。このため、突出部２１の長さは、規定長さＭに余長αを持たせた長さに設定される。よって、スリーブ２０の長さは、防火中空壁Ｗの厚さと、２つの突出部２１の長さ（規定長さＭ＋余長α）との合計長さである。 Therefore, the sleeve 20 has a length enough to secure the prescribed length M for each projecting portion 21 projecting from both surfaces Wa of the fire prevention hollow wall W. As shown in FIG. In order to secure the prescribed length M for each projecting portion 21, the length of the projecting portion 21 needs to be longer than the prescribed length M. For this reason, the length of the projecting portion 21 is set to a length obtained by adding an extra length α to the prescribed length M. As shown in FIG. Therefore, the length of the sleeve 20 is the total length of the thickness of the fireproof hollow wall W and the length of the two projecting portions 21 (prescribed length M+surplus length α).
図３又は図４に示すように、スリーブ２０の外周面には指標部２２が設けられている。図５に示すように、指標部２２は、突出部２１の外周面のうち、突出部２１に位置するスリーブ２０の軸方向の端である端２１ａよりも軸方向に沿って防火中空壁Ｗ側へ離間した位置に設けられている。指標部２２は、突出部２１の外周面に巻き付けるべき閉塞シート３０の長さを示している。よって、指標部２２は、突出部２１の端２１ａから軸方向に沿って規定長さＭだけ離れた位置に設けられている。指標部２２は、スリーブ２０の周方向の全体に亘って延びる線によって形成されている。 As shown in FIG. 3 or FIG. 4 , an indicator portion 22 is provided on the outer peripheral surface of the sleeve 20 . As shown in FIG. 5 , the index portion 22 is located on the outer peripheral surface of the protruding portion 21 and is located on the side of the fire prevention hollow wall W along the axial direction from the end 21 a that is the axial end of the sleeve 20 positioned on the protruding portion 21 . It is provided at a spaced apart position. The index portion 22 indicates the length of the closing sheet 30 to be wrapped around the outer peripheral surface of the projecting portion 21 . Therefore, the index portion 22 is provided at a position spaced apart from the end 21a of the projecting portion 21 by a prescribed length M along the axial direction. The index portion 22 is formed by a line extending along the entire circumferential direction of the sleeve 20 .
閉塞シート３０は、長尺シート状である。閉塞シート３０はアルミテープによって形成されている。閉塞シート３０は、アルミニウムの基材３０ａと、基材３０ａの片面に設けられた粘着部３０ｂとから構成されている。粘着部３０ｂは、突出部２１の外周面、及び配線・配管材１３の外周面に貼着可能である。閉塞シート３０の短手方向への寸法は、規定長さＭの倍以上である。本実施形態では、閉塞シート３０の短手方向への寸法は、規定長さＭの２倍以上である。また、閉塞シート３０の長手方向への寸法は、スリーブ２０の周長と同じである。 The blockage sheet 30 has a long sheet shape. The blocking sheet 30 is made of aluminum tape. The closing sheet 30 is composed of an aluminum base material 30a and an adhesive portion 30b provided on one side of the base material 30a. The adhesive portion 30 b can be attached to the outer peripheral surface of the projecting portion 21 and the outer peripheral surface of the wiring/piping member 13 . The dimension of the closure sheet 30 in the lateral direction is at least twice the specified length M. In this embodiment, the dimension of the closing sheet 30 in the short direction is twice or more the prescribed length M. As shown in FIG. Also, the longitudinal dimension of the closure sheet 30 is the same as the circumferential length of the sleeve 20 .
閉塞シート３０は、閉塞シート３０の長手方向に延びる第１長縁３１ａ及び第２長縁３１ｂを有するとともに、閉塞シート３０の短手方向に延びる第１短縁３２ａ及び第２短縁３２ｂを有する。また、閉塞シート３０において、第１短縁３２ａ及び第２短縁３２ｂを２等分する位置を通過する直線を中心線Ｎとする。 The closure sheet 30 has a first long edge 31a and a second long edge 31b extending in the longitudinal direction of the closure sheet 30, and has a first short edge 32a and a second short edge 32b extending in the width direction of the closure sheet 30. . A center line N is defined as a straight line passing through a position that bisects the first short edge 32a and the second short edge 32b of the closing sheet 30 .
図１又は図２に示すように、スリーブ閉塞構造において、閉塞シート３０は、突出部２１の外周面に巻き付けられた状態で突出部２１に貼着されている。また、閉塞シート３０において、突出部２１の端２１ａよりも突出した部分は、配線・配管材１３に向けて寄せ集められ、配線・配管材１３の外周面に貼着されている。その結果、閉塞シート３０は、突出部２１及び配線・配管材１３に架け渡されるとともに、突出部２１から引き出された配線・配管材１３とスリーブ２０における突出部２１との間の隙間を塞ぎ、スリーブ２０の開口を閉塞している。 As shown in FIG. 1 or FIG. 2 , in the sleeve closing structure, the closing sheet 30 is attached to the protrusion 21 while being wrapped around the outer peripheral surface of the protrusion 21 . Moreover, in the blocking sheet 30 , the portion protruding from the end 21 a of the projecting portion 21 is gathered toward the wiring/piping member 13 and adhered to the outer peripheral surface of the wiring/piping member 13 . As a result, the blocking sheet 30 spans over the projecting portion 21 and the wiring/piping material 13, and closes the gap between the wiring/piping material 13 pulled out from the projecting portion 21 and the projecting portion 21 of the sleeve 20, It closes the opening of the sleeve 20 .
スリーブ閉塞構造において、突出部２１の外周面に巻き付けられる端縁である閉塞シート３０の第１長縁３１ａは、スリーブ２０の軸方向に沿って指標部２２を防火中空壁Ｗ側へ超えた位置に位置している。このとき、図５に示すように、閉塞シート３０の中心線Ｎは、突出部２１の端２１ａではなく、端２１ａよりも防火中空壁Ｗ側へ離間した位置に位置している。その結果、突出部２１に巻き付けられた閉塞シート３０は、突出部２１の端２１ａから防火中空壁Ｗ側へ規定長さＭを離れた位置に至るまで突出部２１に巻き付けられている。つまり、閉塞シート３０は、規定長さＭを確保した状態で突出部２１に巻き付けられるとともに、粘着部３０ｂによって突出部２１の外周面に貼着されている。 In the sleeve closing structure, the first long edge 31a of the closing sheet 30, which is the edge wrapped around the outer peripheral surface of the protruding portion 21, is positioned beyond the index portion 22 toward the fire prevention hollow wall W along the axial direction of the sleeve 20. located in At this time, as shown in FIG. 5, the center line N of the closing sheet 30 is located not at the end 21a of the projecting portion 21, but at a position away from the end 21a toward the hollow fire prevention wall W side. As a result, the blocking sheet 30 wound around the projecting portion 21 is wound around the projecting portion 21 from the end 21a of the projecting portion 21 to a position away from the fire prevention hollow wall W side by the specified length M. In other words, the closure sheet 30 is wound around the projecting portion 21 while ensuring the specified length M, and is adhered to the outer peripheral surface of the projecting portion 21 by the adhesive portion 30b.
次に、スリーブ閉塞構造の製造方法を説明する。
まず、図５に示すように、防火中空壁Ｗの両方の間仕切り壁１１の透孔１１ａにスリーブ２０を挿通するとともに、透孔１１ａの内周面とスリーブ２０の外周面との間に充填材１５を充填し、充填材１５を介してスリーブ２０を間仕切り壁１１に支持させ、スリーブ２０を防火中空壁Ｗに設置する。すると、スリーブ２０が防火中空壁Ｗを厚さ方向に貫通する状態で防火中空壁Ｗに設置される。
Next, a method of manufacturing the sleeve closure structure will be described.
First, as shown in FIG. 5, the sleeve 20 is inserted through the through-holes 11a of the partition walls 11 of the fireproof hollow wall W, and the filler material is inserted between the inner peripheral surface of the through-hole 11a and the outer peripheral surface of the sleeve 20. As shown in FIG. 15 is filled, the sleeve 20 is supported by the partition wall 11 through the filler 15, and the sleeve 20 is installed in the fire prevention hollow wall W. Then, the sleeve 20 is installed in the fire prevention hollow wall W in a state of penetrating the fire prevention hollow wall W in the thickness direction.
このとき、スリーブ２０の軸方向の中心を防火中空壁Ｗの厚さ方向の中心と一致させ、スリーブ２０の軸方向の両側を、防火中空壁Ｗの両方の表面Ｗａから同じ長さで突出させる。その結果、同じ長さの突出部２１が防火中空壁Ｗの表面Ｗａから突出した状態に形成されるとともに、スリーブ２０の内側に貫通孔１４が区画される。ここで、スリーブ２０は、各突出部２１を構成する部分の外周面に指標部２２を備えている。指標部２２は、突出部２１の外周面に巻き付けるべき閉塞シート３０の、突出部２１の端２１ａからの規定長さＭを示している。 At this time, the axial center of the sleeve 20 is aligned with the center of the fire prevention hollow wall W in the thickness direction, and both axial sides of the sleeve 20 are protruded from both surfaces Wa of the fire prevention hollow wall W by the same length. . As a result, the protruding portion 21 having the same length is formed to protrude from the surface Wa of the hollow fireproof wall W, and the through hole 14 is defined inside the sleeve 20 . Here, the sleeve 20 is provided with an index portion 22 on the outer peripheral surface of the portion forming each projecting portion 21 . The index portion 22 indicates the prescribed length M of the closing sheet 30 to be wrapped around the outer peripheral surface of the projecting portion 21 from the end 21 a of the projecting portion 21 .
次に、スリーブ２０の内部、つまり貫通孔１４に配線・配管材１３を挿通し、防火中空壁Ｗに配線・配管材１３を貫通させる。次に、各突出部２１に閉塞シート３０の粘着部３０ｂを貼着し、突出部２１の外周面に閉塞シート３０を巻き付ける。このとき、各突出部２１の指標部２２を指標とし、閉塞シート３０における突出部２１に巻き付けられる第１長縁３１ａを、スリーブ２０の軸方向に沿って指標部２２よりも防火中空壁Ｗ側へ離間した位置に位置させる。その後、閉塞シート３０を突出部２１の外周面に巻き付けるとともに粘着部３０ｂにより突出部２１に貼着し、閉塞シート３０をスリーブ２０に装着する。 Next, the wiring/piping member 13 is inserted through the interior of the sleeve 20, that is, through the through hole 14, and the wiring/piping member 13 is passed through the fire prevention hollow wall W. Next, the adhesive portion 30 b of the blocking sheet 30 is attached to each projecting portion 21 and the blocking sheet 30 is wound around the outer peripheral surface of the projecting portion 21 . At this time, using the index portion 22 of each projecting portion 21 as an index, the first long edge 31 a wound around the projecting portion 21 of the blocking sheet 30 is moved along the axial direction of the sleeve 20 toward the fire prevention hollow wall W side of the index portion 22 . be positioned apart from each other. After that, the closing sheet 30 is wrapped around the outer peripheral surface of the projecting portion 21 and adhered to the projecting portion 21 by the adhesive portion 30 b , and the closing sheet 30 is attached to the sleeve 20 .
なお、閉塞シート３０の短手方向の中間に位置する中心線Ｎを突出部２１の端２１ａよりも防火中空壁Ｗ側に位置させることで、閉塞シート３０の第１長縁３１ａを、指標部２２よりも防火中空壁Ｗ側に超えた位置に位置させることができる。その結果、突出部２１に巻き付けられた閉塞シート３０は、突出部２１の端２１ａから規定長さＭを離れた位置に至るまで突出部２１の外周面に巻き付けられる。なお、閉塞シート３０は、突出部２１の周方向全体に巻き付けられる。そして、閉塞シート３０の第１短縁３２ａと第２短縁３２ｂとが突き合わされる。 In addition, by positioning the center line N located in the middle of the width direction of the blocking sheet 30 closer to the fire prevention hollow wall W side than the end 21a of the projecting portion 21, the first long edge 31a of the blocking sheet 30 can be positioned at the index portion. It can be located at a position beyond 22 toward the fire prevention hollow wall W side. As a result, the closing sheet 30 wrapped around the projecting portion 21 is wound around the outer peripheral surface of the projecting portion 21 to a position separated by the prescribed length M from the end 21a of the projecting portion 21 . In addition, the closing sheet 30 is wrapped around the protruding portion 21 in the entire circumferential direction. Then, the first short edge 32a and the second short edge 32b of the closing sheet 30 are butted against each other.
図２に示すように、閉塞シート３０のうち、突出部２１の端２１ａから突出した部分を、配線・配管材１３に向けて寄せ集めながら、突出部２１から引き出された配線・配管材１３の外周面に巻き付け、粘着部３０ｂを配線・配管材１３に貼着する。すると、閉塞シート３０によって、配線・配管材１３と突出部２１との間の隙間が閉塞されるとともに、貫通孔１４が閉塞され、スリーブ閉塞構造が完成する。 As shown in FIG. 2, the wiring/piping member 13 pulled out from the protruding portion 21 is pulled out from the blocking sheet 30 while gathering the portion protruding from the end 21a of the protruding portion 21 toward the wiring/piping member 13. The adhesive portion 30b is adhered to the wiring/piping material 13 by wrapping it around the outer peripheral surface. Then, the closing sheet 30 closes the gap between the wiring/piping member 13 and the projecting portion 21 and also closes the through hole 14 to complete the sleeve closing structure.
上記実施形態によれば、以下のような効果を得ることができる。
（１－１）スリーブ閉塞構造及びスリーブ閉塞装置において、スリーブ２０の突出部２１に指標部２２を設けた。このため、指標部２２を指標として閉塞シート３０を突出部２１の端２１ａから指標部２２を超える位置まで突出部２１に巻き付けることで、突出部２１の端２１ａから規定長さＭだけ離間した位置まで閉塞シート３０を巻き付けることができる。そして、指標部２２が閉塞シート３０によって覆われることで指標部２２が視認できなくなれば、突出部２１に対し規定長さＭの閉塞シート３０を巻き付けたことを確認できる。よって、突出部２１の端２１ａから規定長さＭだけ離間した位置を計測する作業が必要なくなり、スリーブ２０に対し閉塞シート３０が規定長さＭ巻き付けられているかを確認する作業も必要なくなり、閉塞シート３０の設置作業が容易になる。
According to the above embodiment, the following effects can be obtained.
(1-1) In the sleeve closing structure and the sleeve closing device, the protruding portion 21 of the sleeve 20 is provided with the indicator portion 22 . Therefore, by wrapping the closing sheet 30 around the projecting portion 21 from the end 21a of the projecting portion 21 to a position beyond the projecting portion 22 using the indicator portion 22 as an index, the position spaced apart from the end 21a of the projecting portion 21 by the specified length M is obtained. The closing sheet 30 can be wound up to . When the indicator portion 22 is covered with the blocking sheet 30 and the indicator portion 22 becomes invisible, it can be confirmed that the blocking sheet 30 of the specified length M is wrapped around the projecting portion 21 . Therefore, there is no need to measure the position spaced apart by the specified length M from the end 21a of the protruding portion 21, and there is no need to check whether the closing sheet 30 is wound around the sleeve 20 by the specified length M. Installation work of the seat 30 is facilitated.
（１－２）スリーブ閉塞構造及びスリーブ閉塞装置において、閉塞シート３０の短手方向への寸法は、規定長さＭの２倍以上である。このため、閉塞シート３０の短手方向の中間に位置する中心線Ｎを突出部２１の端２１ａよりも防火中空壁Ｗ側に位置させることで、閉塞シート３０の第１長縁３１ａを、指標部２２よりも防火中空壁Ｗ側へ離間した位置に位置させることができる。このため、規定長さＭだけ閉塞シート３０を突出部２１に巻き付ける際、指標部２２に閉塞シート３０の第１長縁３１ａを合わせる作業が必要なくなり、閉塞シート３０を突出部２１に巻き付ける作業がより容易となる。 (1-2) In the sleeve closure structure and sleeve closure device, the dimension of the closure sheet 30 in the lateral direction is twice or more the specified length M. Therefore, by positioning the central line N, which is located in the middle of the short side of the blocking sheet 30, closer to the hollow fire prevention wall W than the end 21a of the projecting portion 21, the first long edge 31a of the blocking sheet 30 can be positioned as an index. It can be located at a position spaced apart from the portion 22 toward the fire prevention hollow wall W side. Therefore, when the blocking sheet 30 is wound around the protruding portion 21 by the prescribed length M, it is not necessary to align the first long edge 31a of the blocking sheet 30 with the index portion 22, and the work of winding the blocking sheet 30 around the protruding portion 21 is eliminated. easier.
（１－３）スリーブ２０は、防火中空壁Ｗの厚さに合わせて長尺な円筒を切断して形成されるのではなく、防火中空壁Ｗの厚さに応じた長さを有する複数種類が予め形成されており、各長さのスリーブ２０毎に指標部２２が設けられている。このため、いずれの長さのスリーブ２０を用いても、スリーブ閉塞構造に指標部２２を設けることができる。 (1-3) The sleeve 20 is not formed by cutting a long cylinder according to the thickness of the fire prevention hollow wall W, but has a length corresponding to the thickness of the fire prevention hollow wall W. are formed in advance, and an index portion 22 is provided for each sleeve 20 of each length. Thus, the indicator 22 can be provided in the sleeve closure structure using any length of sleeve 20 .
（１－４）スリーブ閉塞構造において、閉塞シート３０の長手方向への寸法は、突出部２１の周長と同じであり、閉塞シート３０の短手方向への寸法は、規定長さＭの２倍以上である。このため、閉塞シート３０の短手方向の中間にある中心線Ｎを突出部２１の端２１ａよりも防火中空壁Ｗ側に寄せて閉塞シート３０を突出部２１に巻き付けることで、閉塞シート３０を長手方向に沿って突出部２１に何度も巻き付けなくてもよくなる。しかも閉塞シート３０を１回巻き付けるだけで、規定長さＭの閉塞シート３０を突出部２１に巻き付けることができる。 (1-4) In the sleeve closure structure, the lengthwise dimension of the closure sheet 30 is the same as the peripheral length of the projecting portion 21, and the widthwise dimension of the closure sheet 30 is 2 times the prescribed length M. more than double. Therefore, by winding the blocking sheet 30 around the projecting portion 21 with the central line N in the middle of the lateral direction of the blocking sheet 30 closer to the fire prevention hollow wall W side than the end 21a of the projecting portion 21, the blocking sheet 30 can be closed. It is not necessary to wind the protruding part 21 many times along the longitudinal direction. Moreover, the blocking sheet 30 of the specified length M can be wound around the projecting portion 21 by winding the blocking sheet 30 only once.
（１－５）スリーブ２０を防火中空壁Ｗに設置するとき、指標部２２を防火中空壁Ｗの表面Ｗａから離間させることで、突出部２１の長さを、規定長さＭに余長αを加えた長さにできる。よって、スリーブ２０に指標部２２を設けることで、突出部２１の長さを確保した状態で、スリーブ２０を防火中空壁Ｗに設置する作業が容易となる。 (1-5) When the sleeve 20 is installed on the fire prevention hollow wall W, the length of the protruding portion 21 is set to the specified length M by the extra length α can be added to the length. Therefore, by providing the sleeve 20 with the index portion 22, it becomes easier to install the sleeve 20 on the fire prevention hollow wall W while ensuring the length of the projecting portion 21. As shown in FIG.
（第２の実施形態）
次に、スリーブ、スリーブ閉塞装置、ブッシング、スリーブ閉塞構造、及びスリーブ閉塞構造の製造方法を具体化した第２の実施形態を図６～図８にしたがって説明する。なお、第２の実施形態において、第１の実施形態と同様の部分についてはその詳細な説明を省略する。
(Second embodiment)
Next, a second embodiment embodying a sleeve, a sleeve closure device, a bushing, a sleeve closure structure, and a method of manufacturing the sleeve closure structure will be described with reference to FIGS. 6 to 8. FIG. In addition, in the second embodiment, detailed description of the same parts as in the first embodiment is omitted.
図６に示すように、第２の実施形態のスリーブ閉塞装置及びスリーブ閉塞構造は、スリーブ２０と、スリーブ２０の軸方向両側の突出部２１の端２１ａを覆うブッシング４０と、軸方向両側の突出部２１の外周面及び配線・配管材１３の外周面に巻き付けられた閉塞シート３０と、ブッシング４０に設けられる指標部５０と、を有する。 As shown in FIG. 6, the sleeve closure device and sleeve closure structure of the second embodiment includes a sleeve 20, bushings 40 covering ends 21a of projections 21 on both sides in the axial direction of the sleeve 20, and projections on both sides in the axial direction. It has a blocking sheet 30 wrapped around the outer peripheral surface of the portion 21 and the outer peripheral surface of the wiring/piping member 13 , and an indicator portion 50 provided on the bushing 40 .
ブッシング４０は、合成樹脂によって形成された環状である。図７に示すように、ブッシング４０は、突出部２１に位置するスリーブ２０の軸方向の端２１ａを覆う環状の端壁部４１と、端壁部４１の外周縁から当該端壁部４１の厚さ方向、つまりスリーブ２０の軸方向へ延設された外周壁部４２と、端壁部４１の内周縁から当該端壁部４１の厚さ方向へ突出する内周壁部４３と、を有する。外周壁部４２は、突出部２１の外周面を覆い、内周壁部４３は、突出部２１の内周面を覆う。 The bushing 40 is annular and made of synthetic resin. As shown in FIG. 7 , the bushing 40 includes an annular end wall portion 41 covering the axial end 21 a of the sleeve 20 located at the projecting portion 21 and a thickness of the end wall portion 41 extending from the outer peripheral edge of the end wall portion 41 . It has an outer peripheral wall portion 42 extending in the longitudinal direction, that is, the axial direction of the sleeve 20 , and an inner peripheral wall portion 43 protruding from the inner peripheral edge of the end wall portion 41 in the thickness direction of the end wall portion 41 . The outer peripheral wall portion 42 covers the outer peripheral surface of the projecting portion 21 , and the inner peripheral wall portion 43 covers the inner peripheral surface of the projecting portion 21 .
ブッシング４０の中心軸線Ｙの延びる方向をブッシング４０の軸方向とする。端壁部４１は、突出部２１の端２１ａが当接する内端面４１ａと、端壁部４１の厚さ方向における内端面４１ａの反対側の面に外端面４１ｂを有する。ブッシング４０において、軸方向に沿った内端面４１ａから外周壁部４２の端縁までの寸法は、規定長さＭと同じである。このため、ブッシング４０を突出部２１に装着し、端壁部４１の内端面４１ａを突出部２１の端２１ａに当接させた状態では、外周壁部４２の端縁は、突出部２１の端２１ａから規定長さＭだけ防火中空壁Ｗ側へ離間した位置に位置する。よって、第２の実施形態では、ブッシング４０において、スリーブ２０及びブッシング４０の軸方向における端壁部４１と反対側に位置する外周壁部４２の端縁そのものが指標部５０を構成している。 The direction in which the central axis Y of the bushing 40 extends is defined as the axial direction of the bushing 40 . The end wall portion 41 has an inner end surface 41a with which the end 21a of the projecting portion 21 abuts, and an outer end surface 41b on the surface opposite to the inner end surface 41a in the thickness direction of the end wall portion 41 . In the bushing 40, the dimension from the inner end surface 41a to the edge of the outer peripheral wall portion 42 along the axial direction is the same as the defined length M. As shown in FIG. Therefore, when the bushing 40 is attached to the protruding portion 21 and the inner end surface 41a of the end wall portion 41 is brought into contact with the end 21a of the protruding portion 21, the edge of the outer peripheral wall portion 42 is positioned at the end of the protruding portion 21. It is located at a position separated from 21a toward the fire prevention hollow wall W side by a specified length M. Therefore, in the second embodiment, the end edge of the outer peripheral wall portion 42 of the bushing 40 located on the opposite side of the end wall portion 41 in the axial direction of the sleeve 20 and the bushing 40 itself constitutes the index portion 50 .
図６に示すように、第２の実施形態のスリーブ閉塞構造では、突出部２１に位置するスリーブ２０の軸方向の端２１ａにはブッシング４０が装着されている。そして、スリーブ２０の軸方向両側の突出部２１の外周面及び配線・配管材１３の外周面には、閉塞シート３０がブッシング４０を覆う状態で巻き付けられるとともに、各閉塞シート３０によって端壁部４１から引き出された配線・配管材１３とブッシング４０との間の隙間が塞がれている。ブッシング４０の外周壁部４２の端縁によって指標部５０が設けられている。スリーブ閉塞構造において、各閉塞シート３０は、当該閉塞シート３０における突出部２１に巻き付けられる第１長縁３１ａを、スリーブ２０の軸方向に沿って指標部５０を防火中空壁Ｗ側へ超える位置に位置させて突出部２１に装着されている。 As shown in FIG. 6 , in the sleeve closing structure of the second embodiment, a bushing 40 is attached to the axial end 21 a of the sleeve 20 located at the projecting portion 21 . A blocking sheet 30 is wrapped around the outer peripheral surface of the protruding portion 21 on both sides in the axial direction of the sleeve 20 and the outer peripheral surface of the wiring/piping member 13 so as to cover the bushing 40 . The gap between the wiring/piping material 13 pulled out from the bushing 40 and the bushing 40 is closed. An index portion 50 is provided by the edge of the outer peripheral wall portion 42 of the bushing 40 . In the sleeve closing structure, each closing sheet 30 is positioned so that the first long edge 31a wound around the protruding portion 21 of the closing sheet 30 exceeds the index portion 50 toward the fire prevention hollow wall W side along the axial direction of the sleeve 20. It is positioned and mounted on the projecting portion 21 .
次に、スリーブ閉塞構造の製造方向を説明する。なお、スリーブ２０を防火中空壁Ｗに設置する方法は第１の実施形態と同じであるため、省略する。
図８に示すように、防火中空壁Ｗから突出した突出部２１の端２１ａにブッシング４０を装着し、端２１ａをブッシング４０によって保護する。次に、スリーブ２０の内部、つまり貫通孔１４に配線・配管材１３を挿通し、防火中空壁Ｗに配線・配管材１３を貫通させる。次に、各突出部２１の外周面に閉塞シート３０を巻き付けるとともに粘着部３０ｂを突出部２１の外周面に貼着する。このとき、各ブッシング４０の外周壁部４２の端縁からなる指標部５０を指標とし、閉塞シート３０の第１長縁３１ａを、スリーブ２０の軸方向に沿って指標部５０よりも防火中空壁Ｗ側へ離間した位置まで位置させて閉塞シート３０を突出部２１に巻き付ける。その結果、突出部２１に貼着された閉塞シート３０は、ブッシング４０を外周壁部４２側から覆うとともに、突出部２１の端２１ａから規定長さＭを離れた位置に至るまで突出部２１に貼着される。なお、閉塞シート３０は、突出部２１の周方向全体に巻き付けられる。
Next, the manufacturing direction of the sleeve closure structure will be explained. The method for installing the sleeve 20 on the fireproof hollow wall W is the same as in the first embodiment, so the description is omitted.
As shown in FIG. 8, a bushing 40 is attached to the end 21a of the projection 21 projecting from the hollow fire prevention wall W, and the bushing 40 protects the end 21a. Next, the wiring/piping member 13 is inserted through the interior of the sleeve 20, that is, through the through hole 14, and the wiring/piping member 13 is passed through the fire prevention hollow wall W. Next, the closure sheet 30 is wrapped around the outer peripheral surface of each projecting portion 21 and the adhesive portion 30b is adhered to the outer peripheral surface of the projecting portion 21 .
