　続いて、図８を用いて、実施の形態１に係る間仕切り方法を説明する。
　図８は、実施の形態１に係る間仕切り装置が設けられる梁の鉛直断面図である。 Subsequently, the partitioning method according to the first embodiment will be described with reference to FIG.
FIG. 8 is a vertical cross-sectional view of a beam provided with the partition device according to the first embodiment.
　この例において、右側の通路２ａにおいて保守作業が行われる。右側の通路２ａは、第１通路の例である。左側の通路２ｂは、第２通路の例である。第１通路は、保守作業が行われる通路２である。この例における間仕切り方法は、張り工程と、固定工程と、を備える。 In this example, maintenance work is performed in the passage 2a on the right side. The passage 2a on the right side is an example of the first passage. The left passage 2b is an example of the second passage. The first passage is a passage 2 where maintenance work is performed. The partitioning method in this example includes a tensioning step and a fixing step.
　作業員は、通路２ａの最上部において、かご８の上部に乗り込む。作業員は、間仕切り装置１０のシート１１ａの端部を、対応する巻取り機構１２から繰り出す。作業員は、繰り出されたシート１１ａの端部を、図示されない最も高い位置の梁３ａの通路２ａの側に固定する。このとき、作業員は、繰り出されたシート１１ａの端部を、留め具１３で挟み込んで梁３ａの通路２ａの側のフランジ５に固定する。次に、作業員は、留め具１３の固定ボルト１６を締め込む。これにより、押さえ板１９の滑り止め面２０は、シート１１ａをフランジ５に押し付ける。このとき、作業員は、シート１１ａの張力ロープ１４の間の部分を留め具１３で挟み込んで固定してもよい。あるいは、作業員は、シート１１の張力ロープ１４を含む部分を留め具１３で挟み込んで固定してもよい。 The worker gets into the upper part of the car 8 at the uppermost part of the passage 2a. The worker unwinds the end of the sheet 11a of the partitioning device 10 from the corresponding winding mechanism 12. The worker fixes the end of the drawn sheet 11a to the side of the passage 2a of the beam 3a at the highest position (not shown). At this time, the worker sandwiches the end portion of the drawn sheet 11a with the fastener 13 and fixes it to the flange 5 on the side of the passage 2a of the beam 3a. Next, the worker tightens the fixing bolt 16 of the fastener 13. As a result, the non-slip surface 20 of the pressing plate 19 presses the sheet 11a against the flange 5. At this time, the worker may sandwich and fix the portion of the seat 11a between the tension ropes 14 with the fastener 13. Alternatively, the worker may sandwich and fix the portion of the seat 11 including the tension rope 14 with the fastener 13.
　作業員は、前後方向に隣り合うように複数のシート１１ａを梁３ａに固定する。作業員は、梁３ａにブラケット６が取り付けられている場合に、ブラケット６を前後に挟んでシート１１ａを固定させてもよい。 The worker fixes a plurality of sheets 11a to the beam 3a so as to be adjacent to each other in the front-rear direction. When the bracket 6 is attached to the beam 3a, the worker may sandwich the bracket 6 back and forth to fix the seat 11a.
　次に、作業員は、シート１１ａの張り工程の作業を例えば次のように行う。作業員は、巻取り機構１２からシート１１ａを繰り出しながら、梁３ａの１つ下の梁３ｂの位置までかご８を移動させる。このとき、作業員は、前後方向に隣り合って配置される１組のシート１１ａを、結合部１５によって互いに結合させる。作業員は、シート１１ａを繰り出した巻取り機構１２を、梁３ｂのウェブ４の上に載せる。このとき、シート１１ａは、梁３ａおよび梁３ｂの間に張られている。 Next, the worker performs the work of the tensioning process of the sheet 11a as follows, for example. The worker moves the car 8 to the position of the beam 3b, which is one below the beam 3a, while paying out the sheet 11a from the winding mechanism 12. At this time, the worker joins a set of sheets 11a arranged adjacent to each other in the front-rear direction by the joining portion 15. The worker puts the take-up mechanism 12 that has unwound the sheet 11a on the web 4 of the beam 3b. At this time, the sheet 11a is stretched between the beams 3a and the beams 3b.
　次に、作業員は、シート１１ａの固定工程の作業を例えば次のように行う。作業員は、梁３ａと梁３ｂとの間に張られたシート１１ａの梁３ｂの側の部分を取って、折り線が前後方向に延びるように折り目２１をつける。作業員は、他のシート１１ｂの端部を、対応する巻取り機構１２から繰り出す。作業員は、シート１１ａの折り目２１とシート１１ｂの端部とを、通路２ａの側のフランジ５に接触させて重ね合わせる。作業員は、シート１１ｂを繰り出した巻取り機構１２を、梁３ｂから通路２ａの側に下ろす。作業員は、重ねたシート１１ａの折り目２１およびシート１１ｂの端部を、通路２ａの側のフランジ５とともに留め具１３で挟み込む。次に、作業員は、留め具１３の固定ボルト１６を締め込むことによってシート１１ａおよびシート１１ｂを梁３ｂに固定する。このとき、作業員は、シート１１ａの張力ロープ１４に張力をかけるように、張力ロープ１４を引きながら留め具１３の固定ボルト１６を締め込んでもよい。 Next, the worker performs the work of the fixing step of the sheet 11a as follows, for example. The worker takes a portion of the sheet 11a stretched between the beams 3a and the beam 3b on the side of the beam 3b, and makes a crease 21 so that the fold line extends in the front-rear direction. The worker unwinds the end of the other sheet 11b from the corresponding take-up mechanism 12. The worker brings the crease 21 of the sheet 11a and the end of the sheet 11b into contact with the flange 5 on the side of the aisle 2a and overlaps them. The worker lowers the take-up mechanism 12 that has unwound the sheet 11b from the beam 3b toward the passage 2a. The worker sandwiches the crease 21 of the stacked sheets 11a and the end portion of the sheet 11b with the fastener 13 together with the flange 5 on the side of the passage 2a. Next, the worker fixes the sheet 11a and the sheet 11b to the beam 3b by tightening the fixing bolt 16 of the fastener 13. At this time, the worker may tighten the fixing bolt 16 of the fastener 13 while pulling the tension rope 14 so as to apply tension to the tension rope 14 of the seat 11a.
　次に、作業員は、シート１１ｂの張り工程の作業を例えば次のように行う。作業員は、固定工程において梁３ｂに固定されたシート１１ｂを巻取り機構１２から繰り出しながら、梁３ｂの１つ下の図８に図示されない梁３ｃの位置までかご８を移動させる。このとき、作業員は、前後方向に隣り合って配置される１組のシート１１ｂを、結合部１５によって互いに結合させる。作業員は、シート１１ｂを繰り出した巻取り機構１２を、梁３ｃのウェブ４の上に載せる。このとき、シート１１ｂは、梁３ｂおよび梁３ｃの間に張られている。 Next, the worker performs the work of the sheet 11b tensioning process as follows, for example. The worker moves the car 8 to the position of the beam 3c, which is one step below the beam 3b and is not shown in FIG. 8, while unwinding the sheet 11b fixed to the beam 3b from the winding mechanism 12. At this time, the worker joins a set of sheets 11b arranged adjacent to each other in the front-rear direction by the joining portion 15. The worker puts the take-up mechanism 12 that has unwound the sheet 11b on the web 4 of the beam 3c. At this time, the sheet 11b is stretched between the beams 3b and the beams 3c.
　このように、作業員は、張り工程と固定工程とを交互に繰り返すことで昇降路１の上部から下部にかけて間仕切り作業を行う。 In this way, the worker performs the partitioning work from the upper part to the lower part of the hoistway 1 by alternately repeating the tensioning process and the fixing process.
　以上に説明したように、実施の形態１に係る間仕切り装置１０は、第１シートと、留め具１３と、を備える。第１シートは、第１梁の第１通路の側から第２梁の第１通路の側にわたって張られる。留め具１３は、折り線が前後に延びる第１シートの折り目２１を第２梁の第１通路の側において第２シートとともに挟み込んで固定する。ここで、第１梁は、第１通路および第２通路の間で前後に延びる。第２梁は、第１通路および第２通路の間の第１梁の下方において前後に延びる。第１通路および第２通路は、エレベーターの昇降路１において左右に隣り合う通路２である。第２シートは、第２梁の第１通路の側において下方に張られる。
　また、実施の形態１に係る昇降路１の間仕切り方法は、張り工程と、固定工程と、を備える。張り工程は、第１梁の第１通路の側に固定された第１シートを、第１梁の第１通路の側において、第１梁および第２梁の間に張る工程である。固定工程は、張り工程の後に、折り線が前後方向に延びるように第１シートに折り目２１を折って、第２シートとともに第２梁の第１通路の側に留め具で挟み込んで固定する工程である。 As described above, the partition device 10 according to the first embodiment includes a first sheet and a fastener 13. The first sheet is stretched from the side of the first passage of the first beam to the side of the first passage of the second beam. The fastener 13 sandwiches and fixes the crease 21 of the first sheet whose fold line extends in the front-rear direction together with the second sheet on the side of the first passage of the second beam. Here, the first beam extends back and forth between the first passage and the second passage. The second beam extends back and forth below the first beam between the first and second passages. The first passage and the second passage are passages 2 adjacent to each other on the left and right sides of the elevator hoistway 1. The second sheet is stretched downward on the side of the first passage of the second beam.
Further, the partitioning method of the hoistway 1 according to the first embodiment includes a tensioning step and a fixing step. The tensioning step is a step of stretching the first sheet fixed to the side of the first passage of the first beam between the first beam and the second beam on the side of the first passage of the first beam. The fixing step is a step of folding the crease 21 on the first sheet so that the fold line extends in the front-rear direction after the tensioning step, and sandwiching and fixing the crease 21 together with the second sheet on the side of the first passage of the second beam. Is.
　これにより、昇降路１において作業区画を分けるシート１１は、一貫して梁３の第１通路の側に張られる。作業員または作業における装置などは、間仕切り装置１０の取付けおよび取外しにおいて、隣の第２通路にはみ出さない。これにより、間仕切り装置１０を着脱するときにおいても、隣の第２通路への干渉が抑えられる。また、シート１１は、上下に並ぶ梁３の間に個別に張られる。一般に、梁３の間隔において、昇降路１の長さによる違いは少ない。このため、長さの異なる昇降路１においても同じ間仕切り装置１０が利用できる。これにより、保守作業のための装置の管理などがしやすくなる。また、シート１１は、上下に並ぶ梁３ごとに張られる。このため、シート１１に張力をかけることが容易になる。このため、間仕切り作業がやりやすくなる。 As a result, the sheet 11 that divides the work section in the hoistway 1 is consistently stretched to the side of the first passage of the beam 3. The worker or the device in the work does not protrude into the adjacent second passage when the partition device 10 is attached and detached. As a result, even when the partition device 10 is attached / detached, interference with the adjacent second passage can be suppressed. Further, the sheets 11 are individually stretched between the beams 3 arranged vertically. In general, there is little difference in the distance between the beams 3 depending on the length of the hoistway 1. Therefore, the same partition device 10 can be used in the hoistways 1 having different lengths. This makes it easier to manage the equipment for maintenance work. Further, the sheet 11 is stretched for each beam 3 arranged vertically. Therefore, it becomes easy to apply tension to the sheet 11. Therefore, the partition work becomes easy.
　また、第１シートは、結合部１５を左右の端部に有する。結合部１５は、第１梁および第２梁の間において前後に隣り合って張られる他の第１シートと結合する部分である。
　また、張り工程は、第１シートを、第１梁および第２梁の間において前後に隣り合って張られる他の第１シートと結合させる工程を含む。 The first sheet also has joints 15 at the left and right ends. The connecting portion 15 is a portion that joins with another first sheet stretched adjacent to each other in the front-rear direction between the first beam and the second beam.
Further, the tensioning step includes a step of joining the first sheet with another first sheet stretched adjacent to each other in the front-rear direction between the first beam and the second beam.
　これにより、作業員は、幅の異なる複数の第１シートを組み合わせて使用できる。このため、奥行きが異なる昇降路１においても同じ間仕切り装置１０が利用できる。これにより、保守作業のための装置の管理などがしやすくなる。 As a result, the worker can use a combination of a plurality of first sheets having different widths. Therefore, the same partition device 10 can be used even in the hoistways 1 having different depths. This makes it easier to manage the equipment for maintenance work.
　また、第１シートは、第１梁および第２梁の間において上下方向に張られる張力ロープ１４を面内に含む。 Further, the first sheet includes a tension rope 14 stretched in the vertical direction between the first beam and the second beam in the plane.
　面内に含まれる張力ロープ１４が第１梁および第２梁の間に張られることによって、シート１１は、面外方向への振動が抑えられる。これにより、第２通路においてかご８が走行する場合においても、風圧などによる間仕切り装置１０のシート１１の振動が抑えられる。 The tension rope 14 included in the plane is stretched between the first beam and the second beam, so that the seat 11 is suppressed from vibrating in the out-of-plane direction. As a result, even when the car 8 travels in the second passage, the vibration of the seat 11 of the partition device 10 due to wind pressure or the like is suppressed.
　また、間仕切り装置１０は、巻取り機構１２を備える。巻取り機構１２は、第１シートが第１梁および第２梁の間に張られるときの前後方向を巻取り軸として、第１シートを張力ロープ１４とともに巻き取って収納する。 Further, the partition device 10 includes a winding mechanism 12. The winding mechanism 12 winds and stores the first sheet together with the tension rope 14 with the winding axis in the front-rear direction when the first sheet is stretched between the first beam and the second beam.
　巻取り機構１２によって、作業員は、第１シートを必要な長さだけを繰り出して使用できる。これにより、梁３の間隔が異なる昇降路１においても同じ間仕切り装置１０が利用できる。これにより、保守作業のための装置の管理などがしやすくなる。 With the winding mechanism 12, the worker can use the first sheet by paying out only the required length. As a result, the same partition device 10 can be used even in the hoistway 1 where the intervals between the beams 3 are different. This makes it easier to manage the equipment for maintenance work.
　また、留め具１３は、押さえ板１９の滑り止め面２０によってシート１１を押さえつけて固定する。このため、シート１１がメッシュシートであっても、シート１１は、固定ボルト１６の締結などによって巻き込まれにくくなる。また、シート１１が固定ボルト１６に巻き込まれないので、固定ボルト１６が巻き戻りにくくなる。このため、シート１１がより確実に固定される。 Further, the fastener 13 presses and fixes the sheet 11 by the non-slip surface 20 of the pressing plate 19. Therefore, even if the sheet 11 is a mesh sheet, the sheet 11 is less likely to be caught by fastening the fixing bolts 16. Further, since the sheet 11 is not caught in the fixing bolt 16, the fixing bolt 16 is difficult to rewind. Therefore, the sheet 11 is more reliably fixed.
　なお、間仕切り装置１０は、巻取り機構１２を備えなくてもよい。このとき、梁３の間に張られるシート１１の上下の端部の少なくとも一方は、シート１１のみで巻かれて収納されてもよい。また、シート１１の上下の端部の少なくとも一方は、例えば蛇腹状に折り畳まれて収納されてもよい。 The partition device 10 does not have to include the winding mechanism 12. At this time, at least one of the upper and lower ends of the sheet 11 stretched between the beams 3 may be wound and stored only by the sheet 11. Further, at least one of the upper and lower ends of the sheet 11 may be folded and stored in a bellows shape, for example.
　また、シート１１は、張力ロープ１４を含まなくてもよい。 Further, the sheet 11 does not have to include the tension rope 14.
　また、実施の形態１に係る間仕切り方法および間仕切り装置１０は、Ｈ型鋼ではない梁３を有するエレベーターについても適用できる。梁３は、例えば溝型鋼などであってもよい。 Further, the partitioning method and the partitioning device 10 according to the first embodiment can be applied to an elevator having a beam 3 which is not H-shaped steel. The beam 3 may be, for example, channel steel.
　また、以上の例において左右を入れ替えた場合においても、実施の形態１に係る間仕切り方法および間仕切り装置１０は、同様に適用できる。 Further, even when the left and right sides are exchanged in the above example, the partitioning method and the partitioning device 10 according to the first embodiment can be similarly applied.

　留め具は、第１固定部２２ａと、第２固定部２２ｂと、を有する。第１固定部２２ａおよび第２固定部２２ｂは、コ字状の形状である。この例において、第１固定部２２ａおよび第２固定部２２ｂは、互いに対称に設けられる。第１固定部２２ａおよび第２固定部２２ｂは、互いに背中合わせに取り付けられる。 The fastener has a first fixing portion 22a and a second fixing portion 22b. The first fixing portion 22a and the second fixing portion 22b have a U-shape. In this example, the first fixing portion 22a and the second fixing portion 22b are provided symmetrically with each other. The first fixing portion 22a and the second fixing portion 22b are attached back to back to each other.
　第１固定部２２ａは、固定ボルト２３を備える。固定ボルト２３は、例えば蝶ボルトである。固定ボルト２３は、例えば第１固定部２２ａのコ字状の部分のうち互いに対向する１組の部分の一方に設けられる。第１固定部２２ａは、歯部１７を有する。歯部１７は、固定ボルト２３が設けられる部分と対向する部分に設けられる。歯部１７は、波状の部分である。第１固定部２２ａは、押さえ板１９を備える。押さえ板１９は、固定ボルト２３の先端に設けられる。押さえ板１９は、例えば矩形の板状部材である。押さえ板１９は、固定ボルト２３が取り付けられる面の反対側に滑り止め面２０を有する。滑り止め面２０は、例えばゴム素材などにより形成される。滑り止め面２０は、表面にシート１１のメッシュにかみ合う凹凸を有していてもよい。 The first fixing portion 22a includes a fixing bolt 23. The fixing bolt 23 is, for example, a wing bolt. The fixing bolt 23 is provided on, for example, one of a set of U-shaped portions of the first fixing portion 22a facing each other. The first fixing portion 22a has a tooth portion 17. The tooth portion 17 is provided at a portion facing the portion where the fixing bolt 23 is provided. The tooth portion 17 is a wavy portion. The first fixing portion 22a includes a pressing plate 19. The pressing plate 19 is provided at the tip of the fixing bolt 23. The holding plate 19 is, for example, a rectangular plate-shaped member. The holding plate 19 has a non-slip surface 20 on the opposite side of the surface on which the fixing bolt 23 is attached. The non-slip surface 20 is formed of, for example, a rubber material. The non-slip surface 20 may have irregularities on the surface that mesh with the mesh of the sheet 11.
　第２固定部２２ｂは、第１固定部２２ａと同様に、固定ボルト２３と、押さえ板１９と、を備える。第２固定部２２ｂは、第１固定部２２ａと同様に、歯部１７を有する。第１固定部２２ａと第２固定部２２ｂとにおいて、固定ボルト２３は、同じ方向に向けて設けられる。 The second fixing portion 22b includes a fixing bolt 23 and a holding plate 19 in the same manner as the first fixing portion 22a. The second fixing portion 22b has a tooth portion 17 like the first fixing portion 22a. The fixing bolts 23 are provided in the same direction in the first fixing portion 22a and the second fixing portion 22b.
　続いて、図１０を用いて、実施の形態２に係る間仕切り方法を説明する。
　図１０は、実施の形態２に係る間仕切り装置が設けられる梁の鉛直断面図である。 Subsequently, the partitioning method according to the second embodiment will be described with reference to FIG.
FIG. 10 is a vertical cross-sectional view of a beam provided with the partition device according to the second embodiment.
　作業員は、図示されない最も高い位置の梁３ａに固定されたシート１１ａの張り工程の作業を例えば次のように行う。作業員は、巻取り機構１２からシート１１ａを繰り出しながら、梁３ａの１つ下の梁３ｂの位置までかご８を移動させる。このとき、作業員は、前後方向に隣り合って配置される１組のシート１１ａを、結合部１５によって互いに結合させる。作業員は、シート１１ａを繰り出した巻取り機構１２を、梁３ｂのウェブ４の上に載せる。このとき、シート１１ａは、梁３ａおよび梁３ｂの間に張られている。 The worker performs the work of the tensioning process of the sheet 11a fixed to the beam 3a at the highest position (not shown) as follows, for example. The worker moves the car 8 to the position of the beam 3b, which is one below the beam 3a, while paying out the sheet 11a from the winding mechanism 12. At this time, the worker joins a set of sheets 11a arranged adjacent to each other in the front-rear direction by the joining portion 15. The worker puts the take-up mechanism 12 that has unwound the sheet 11a on the web 4 of the beam 3b. At this time, the sheet 11a is stretched between the beams 3a and the beams 3b.
　次に、作業員は、シート１１ａの固定工程の作業を例えば次のように行う。 Next, the worker performs the work of the fixing step of the sheet 11a as follows, for example.
　作業員は、第１固定部２２ａによって、梁３ｂの通路２ａの側のフランジ５に留め具１３を取り付ける。このとき、作業員は、第１固定部２２ａの押さえ板１９および歯部１７によってフランジ５の上端を挟み込むように配置する。第１固定部２２ａは、固定ボルト２３がフランジ５より通路２ａの側になるように配置される。作業員は、第１固定部２２ａの固定ボルト２３を例えば手で締め込むことによって、留め具１３を梁３ｂに固定する。 The worker attaches the fastener 13 to the flange 5 on the side of the passage 2a of the beam 3b by the first fixing portion 22a. At this time, the worker is arranged so as to sandwich the upper end of the flange 5 by the pressing plate 19 and the tooth portion 17 of the first fixing portion 22a. The first fixing portion 22a is arranged so that the fixing bolt 23 is closer to the passage 2a than the flange 5. The worker fixes the fastener 13 to the beam 3b by, for example, manually tightening the fixing bolt 23 of the first fixing portion 22a.
　その後、作業員は、梁３ａと梁３ｂとの間に張られたシート１１ａの梁３ｂの側の部分を取って、折り線が前後方向に延びるように折り目２１をつける。作業員は、他のシート１１ｂの端部を、対応する巻取り機構１２から繰り出す。作業員は、シート１１ａの折り目２１とシート１１ｂの端部とを、シート１１ｂが通路２ａの側になるように重ね合わせる。作業員は、シート１１ａおよびシート１１ｂを重ねて折り目２１をつけてもよい。作業員は、重ねたシート１１ａの折り目２１およびシート１１ｂの端部を、梁３ｂに固定された留め具の第２固定部２２ｂの押さえ板１９および歯部１７の間に挟み込む。作業員は、第２固定部２２ｂの固定ボルト２３を例えば手で締め込むことによって、シート１１ａの折り目２１をシート１１ｂとともに挟み込んで梁３ｂに固定する。このとき、作業員は、シート１１ｂを留め具１３より上方にめくった状態で固定ボルト２３を締め込む。作業員は、シート１１ａの張力ロープ１４に張力をかけるように、張力ロープ１４を引きながら留め具１３の固定ボルト２３を締め込んでもよい。シート１１ａおよびシート１１ｂを梁３ｂに固定した後に、作業員は、シート１１ｂを繰り出した巻取り機構１２を、梁３ｂから通路２ａの側に下ろす。 After that, the worker takes the portion of the sheet 11a stretched between the beams 3a and the beam 3b on the side of the beam 3b, and makes a crease 21 so that the fold line extends in the front-rear direction. The worker unwinds the end of the other sheet 11b from the corresponding take-up mechanism 12. The worker superimposes the crease 21 of the sheet 11a and the end portion of the sheet 11b so that the sheet 11b is on the side of the aisle 2a. The worker may make a crease 21 by overlapping the sheets 11a and 11b. The worker sandwiches the crease 21 of the overlapped sheet 11a and the end portion of the sheet 11b between the holding plate 19 and the tooth portion 17 of the second fixing portion 22b of the fastener fixed to the beam 3b. The worker sandwiches the crease 21 of the sheet 11a together with the sheet 11b and fixes it to the beam 3b by, for example, manually tightening the fixing bolt 23 of the second fixing portion 22b. At this time, the worker tightens the fixing bolt 23 with the seat 11b turned upward above the fastener 13. The worker may tighten the fixing bolt 23 of the fastener 13 while pulling the tension rope 14 so as to apply tension to the tension rope 14 of the seat 11a. After fixing the sheet 11a and the sheet 11b to the beam 3b, the worker lowers the winding mechanism 12 that has unwound the sheet 11b from the beam 3b to the side of the passage 2a.
　次に、作業員は、シート１１ｂの張り工程の作業を行う。その後、作業員は、シート１１ｂの固定工程の作業を行う。このように、作業員は、張り工程と固定工程とを交互に繰り返すことで昇降路１の上部から下部にかけて間仕切り作業を行う。 Next, the worker performs the work of the sheet 11b tensioning process. After that, the worker performs the work of the fixing step of the sheet 11b. In this way, the worker performs the partitioning work from the upper part to the lower part of the hoistway 1 by alternately repeating the tensioning process and the fixing process.
　以上に説明したように、実施の形態２に係る間仕切り装置１０の留め具１３は、第１固定部２２ａと、第２固定部２２ｂと、を有する。第１固定部２２ａは、第２梁に取り付けられる。第２固定部２２ｂは、第１シートの折り目を前記第２シートとともに挟み込んで固定する。
　また、実施の形態２に係る昇降路１の間仕切り方法の固定工程は、第１工程と、第２工程と、を備える。第１工程は、留め具１３を第２梁の第１通路の側に取り付ける工程である。第２工程は、第２梁に取り付けられた留め具１３で、第１シートの折り目２１を第２シートとともに挟み込んで固定する工程である。 As described above, the fastener 13 of the partition device 10 according to the second embodiment has a first fixing portion 22a and a second fixing portion 22b. The first fixing portion 22a is attached to the second beam. The second fixing portion 22b sandwiches and fixes the crease of the first sheet together with the second sheet.
Further, the fixing step of the partitioning method of the hoistway 1 according to the second embodiment includes a first step and a second step. The first step is a step of attaching the fastener 13 to the side of the first passage of the second beam. The second step is a step of sandwiching and fixing the crease 21 of the first sheet together with the second sheet by the fastener 13 attached to the second beam.
　シート１１を梁３に固定する工程は、留め具１３を梁３に固定する工程と、シート１１を留め具１３に固定する工程と、に分離される。このため、作業員は、同時に３つの部分を固定する作業を行わなくてもよい。このため、間仕切り作業がよりやりやすくなる。 The step of fixing the sheet 11 to the beam 3 is divided into a step of fixing the fastener 13 to the beam 3 and a step of fixing the sheet 11 to the fastener 13. Therefore, the worker does not have to perform the work of fixing the three parts at the same time. Therefore, the partition work becomes easier.
　また、第１固定部２２ａと第２固定部２２ｂとにおいて、固定ボルト２３は、同じ方向に向けて設けられるので、作業員は、梁３に対して一方の側から一貫して作業を行うことができる。このため、間仕切り作業がよりやりやすくなる。 Further, since the fixing bolts 23 are provided in the same direction in the first fixing portion 22a and the second fixing portion 22b, the worker consistently performs the work on the beam 3 from one side. Can be done. Therefore, the partition work becomes easier.
　本発明に係る間仕切り方法は、昇降路における保守作業に適用できる。本発明に係る間仕切り装置は、当該間仕切り方法に適用できる。 The partitioning method according to the present invention can be applied to maintenance work in a hoistway. The partition device according to the present invention can be applied to the partition method.
