Description

本開示は、主に、建物に敷設された電線を支持する電線支持装置に係わる。 The present disclosure mainly relates to an electric wire support device that supports an electric wire laid in a building.

従来より、建物に配置される各種の電気機器への電力供給のため電線が建物に敷設されるが、このような電線は、例えば、ラックを設けてその上に載置したり、梁に紐でしばりつけたりして保持されている。
一方、電線を建物に敷設する敷設工事においては、電線を目的とする場所まで送り出すのをアシストするため、敷設ルートに沿って必要箇所に回転自在の回転体を配置している。そして、回転体の外周面に電線を載せて回転体の回転により、電線の送り出しを円滑化している。そこで、このような電線の送り出しを円滑に行うための送出支援具に関し、様々な検討がなされている（例えば、特許文献１参照。）。 BACKGROUND ART Conventionally, electric wires are laid in a building for supplying electric power to various electric devices arranged in the building.For example, such an electric wire is provided on a rack and placed on it, or a string is attached to a beam. It is held by squeezing it.
On the other hand, in the laying work for laying an electric wire in a building, in order to assist in sending the electric wire to a desired place, a rotatable body is arranged at a required position along the laying route. Then, the electric wire is placed on the outer peripheral surface of the rotating body to rotate the rotating body so that the electric wire is smoothly fed out. Therefore, various studies have been made on a delivery support tool for smoothly delivering such an electric wire (see, for example, Patent Document 1).

ところで、敷設工事において必要箇所に搬入されて据え付けられた送出支援具は、敷設工事終了後に撤去する必要があり、その後、さらに、電線を支持する電線支持装置を搬入して据え付ける必要がある。
しかし、電線の敷設ルートとなるスペースは、天井裏など狭い空間であり、さらに、近年の居住空間の拡大に伴って狭くなる傾向にある。このため、上記のような送出支援具の撤去や電線支持装置の据え付けが煩雑になっており、何らかの対策が必要になっている。 By the way, the delivery support tool carried in and installed in a necessary place in the laying work needs to be removed after the laying work is completed, and then the wire support device for supporting the wires needs to be carried in and installed.
However, the space that serves as the route for laying the electric wire is a narrow space such as the back of the ceiling, and tends to become smaller with the recent expansion of the living space. For this reason, the removal of the above-mentioned delivery support tool and the installation of the electric wire support device are complicated, and some measure is required.

また、電線の敷設工事では、電線を最終的な常設の位置に敷設する前に、何度も仮設して電線の位置を変更する場合が多い。このため、仮設工事を繰り返して常設の位置に敷設する必要がある場合、仮設工事のたびに、上記のような送出支援具の撤去や電線支持装置の据え付けを繰り返す必要があり、一層、煩雑さが増している。したがって、このような観点でも、何らかの対策が必要となっている。 In addition, in the electric wire laying work, before the electric wire is laid in the final permanent position, it is often the case that the position of the electric wire is changed by temporary installation. For this reason, if it is necessary to repeat temporary construction and lay it in a permanent position, it is necessary to repeat the above-mentioned removal of the delivery support tool and installation of the electric wire support device every time the temporary construction is carried out. Is increasing. Therefore, some measures are required from this viewpoint as well.

本開示を実施するための形態を以下の実施例により詳細に説明する。 Modes for carrying out the present disclosure will be described in detail by the following examples.

〔実施例１の構成〕
実施例１の電線支持装置１の構成を、図１および図２を用いて説明する。
電線支持装置１は、建物に敷設された電線２を支持するものであり、電線敷設工事における送出支援具の据え付けや撤去が困難な狭いスペースに好適に利用することができるものである。
電線支持装置１は、次の電線載置部３および回転阻止部４を備える。以下、電線載置部３および回転阻止部４に関し、順次、説明する。 [Structure of Embodiment 1]
The configuration of the electric wire support device 1 according to the first embodiment will be described with reference to FIGS. 1 and 2.
The electric wire support device 1 supports the electric wires 2 laid in a building, and can be suitably used in a narrow space where it is difficult to install or remove the delivery support tool in the electric wire laying work.
The electric wire support device 1 includes the following electric wire placement portion 3 and rotation prevention portion 4. Hereinafter, the wire mounting portion 3 and the rotation blocking portion 4 will be sequentially described.

まず、電線載置部３は、軸心の周囲に回転自在の回転体５を有して所定の箇所に取り付けられ、この回転体５の外周面に電線２が載る、というものである。ここで、回転体５は、絶縁性樹脂を素材とするものであり、次の円筒部６および２つのフランジ７Ａ、７Ｂを有する。まず、円筒部６は、自身の外周面６Ａに電線２が載る部分であり、自身の軸方向に貫通する内周８を有する。 First, the electric wire mounting portion 3 has a rotatable body 5 which is rotatable around an axis and is attached at a predetermined position, and the electric wire 2 is mounted on the outer peripheral surface of the rotatable body 5. Here, the rotating body 5 is made of an insulating resin, and has the following cylindrical portion 6 and two flanges 7A and 7B. First, the cylindrical portion 6 is a portion where the electric wire 2 is placed on the outer peripheral surface 6A of the cylindrical portion 6, and has an inner periphery 8 that penetrates in the axial direction of the cylindrical portion 6.

また、フランジ７Ａ、７Ｂは、それぞれ、円筒部６の一端、他端に設けられて電線２の一端側、他端側への移動を規制する部分である。また、フランジ７Ａ、７Ｂは、それぞれ、内周８の一端側、他端側の開口を形成している。なお、円筒部６の外周面６Ａを含む回転体５の表面は、絶縁性を有する。 The flanges 7A and 7B are portions provided at one end and the other end of the cylindrical portion 6, respectively, and restrict the movement of the electric wire 2 to the one end side and the other end side. Further, the flanges 7A and 7B respectively form openings on one end side and the other end side of the inner circumference 8. The surface of the rotating body 5 including the outer peripheral surface 6A of the cylindrical portion 6 has an insulating property.

次に、回転阻止部４は、回転体５の回転を阻止する、というものである。
回転阻止部４は、回転体５の軸方向一方側、他方側それぞれの側への移動を規制する第１、第２規制部１０、１１を有し、第１、第２規制部１０、１１により、回転体５を挟むことで回転体５の回転を阻止する。 Next, the rotation blocking unit 4 blocks the rotation of the rotating body 5.
The rotation blocking portion 4 has first and second regulating portions 10 and 11 that regulate the movement of the rotating body 5 to the one side and the other side in the axial direction, respectively. Thus, the rotation of the rotating body 5 is prevented by sandwiching the rotating body 5.

また、回転阻止部４は、回転体５の内周８を貫通する軸部１２、および、軸部１２に設けられて回転体５の内周８の外側に配置される第１ネジ部１３を有する。さらに、第１規制部１０は軸部１２に固定され、第２規制部１１は第１ネジ部１３に螺合する第２ネジ部１４を有する。そして、第１、第２ネジ部１３、１４の螺合により、第２規制部１１を第１規制部１０に近付けることで、回転体５を挟む。 In addition, the rotation blocking portion 4 includes a shaft portion 12 penetrating the inner circumference 8 of the rotating body 5 and a first screw portion 13 provided on the shaft portion 12 and arranged outside the inner circumference 8 of the rotating body 5. Have. Further, the first restricting portion 10 is fixed to the shaft portion 12, and the second restricting portion 11 has a second screw portion 14 that is screwed into the first screw portion 13. Then, the rotating body 5 is sandwiched by bringing the second regulating portion 11 closer to the first regulating portion 10 by screwing the first and second screw portions 13 and 14.

より具体的には、回転阻止部４は、例えば、ボルトおよびナットの組み合わせである。そして、例えば、ボルトの頭部、ナットが、それぞれ第１、第２規制部１０、１１として機能し、ボルト軸部１２に設けられた雄ネジが第１ネジ部として機能し、ナットの雌ネジが第２ネジ部として機能する（以下、第１規制部１０をボルト頭部１０、第２規制部１１をナット１１、軸部１２をボルト軸部１２と呼ぶことがある。）。 More specifically, the rotation blocking unit 4 is, for example, a combination of bolts and nuts. Then, for example, the head of the bolt and the nut function as the first and second restricting portions 10 and 11, respectively, the male screw provided on the bolt shaft portion 12 functions as the first screw portion, and the female screw of the nut. Function as a second screw portion (hereinafter, the first regulating portion 10 may be referred to as a bolt head portion 10, the second regulating portion 11 may be referred to as a nut 11, and the shaft portion 12 may be referred to as a bolt shaft portion 12).

また、電線載置部３は、複数の回転体５を有し、複数の回転体５は、軸心が互いに平行、かつ、軸心に垂直な方向に並ぶ軸垂直列１６を形成している。
具体的には、電線支持装置１には、回転体５と同数の回転阻止部４が装備され、回転体５と回転阻止部４との組み合わせが、回転体５の軸心に垂直な方向に並ぶように、所定の被取付部材１７に取り付けられている。 Further, the electric wire mounting portion 3 has a plurality of rotating bodies 5, and the plurality of rotating bodies 5 form axis vertical rows 16 whose axes are parallel to each other and are arranged in a direction perpendicular to the axes. ..
Specifically, the electric wire support device 1 is equipped with the same number of rotation blocking units 4 as the rotating bodies 5, and the combination of the rotating bodies 5 and the rotation blocking units 4 is arranged in a direction perpendicular to the axis of the rotating body 5. It is attached to a predetermined attached member 17 so as to be lined up.

ここで、被取付部材１７は、例えば、回転体５および回転阻止部４が取り付けられる被取付部１８、および、被取付部材１７を建物の所定の箇所に装着するための装着部１９を有する。また、被取付部１８では、回転体５および回転阻止部４を取り付けるための取付孔２０が並んでいる。 Here, the attached member 17 has, for example, an attached portion 18 to which the rotating body 5 and the rotation blocking portion 4 are attached, and an attaching portion 19 for attaching the attached member 17 to a predetermined portion of a building. Further, in the attached portion 18, the attachment holes 20 for attaching the rotating body 5 and the rotation blocking portion 4 are arranged.

さらに、回転体５および回転阻止部４は、次のような円筒部２２Ａおよびフランジ２２Ｂを有する２つの軸受部材２２とともに被取付部１８に取り付けられている。
すなわち、円筒部２２Ａは、支持すべき軸部材としてボルト軸部１２が通る貫通孔２２Ｃを形成し、ボルト軸部１２から負荷されるラジアル荷重を受ける。 Further, the rotating body 5 and the rotation blocking portion 4 are attached to the attached portion 18 together with the two bearing members 22 having the following cylindrical portion 22A and flange 22B.
That is, the cylindrical portion 22A forms a through hole 22C through which the bolt shaft portion 12 passes as a shaft member to be supported, and receives a radial load applied from the bolt shaft portion 12.

また、円筒部２２Ａの厚さは、内周８の半径とボルト軸部１２の半径との差分に略一致しており、円筒部２２Ａは、貫通孔２２Ｃにボルト軸部１２が通った状態で内周８に嵌まることができる。さらに、フランジ２２Ｂは、円筒部２２Ａの片方の端に設けられて貫通孔２２Ｃの開口を形成し、円筒部２２Ａが内周８に嵌まることで回転体５から負荷されるスラスト荷重を受ける。なお、軸受部材２２は、例えば、ポリウレタン等の合成樹脂を発泡成形したものである。 Further, the thickness of the cylindrical portion 22A is substantially equal to the difference between the radius of the inner circumference 8 and the radius of the bolt shaft portion 12, and the cylindrical portion 22A is in a state where the bolt shaft portion 12 passes through the through hole 22C. It can fit on the inner circumference 8. Further, the flange 22B is provided at one end of the cylindrical portion 22A to form the opening of the through hole 22C, and the cylindrical portion 22A is fitted on the inner circumference 8 to receive the thrust load applied from the rotating body 5. The bearing member 22 is formed by foaming a synthetic resin such as polyurethane.

そして、フランジ７Ａ、７Ｂの一端側、他端側から、それぞれ軸受部材２２の円筒部２２Ａを内周８に嵌めることで、軸受部材２２を回転体５に装着する。また、回転体５の一端側に装着された軸受部材２２の貫通孔２２Ｃにボルト軸部１２を通し、ボルト頭部１０とフランジ７Ａとによりフランジ２２Ｂを挟む。このとき、ボルト軸部１２の他端は、回転体５の他端側に装着された軸受部材２２の貫通孔２２Ｃを通ってフランジ７Ｂから他端側に突き抜けている。 Then, the bearing member 22 is attached to the rotating body 5 by fitting the cylindrical portion 22A of the bearing member 22 into the inner circumference 8 from one end side and the other end side of the flanges 7A and 7B, respectively. Further, the bolt shaft portion 12 is passed through the through hole 22C of the bearing member 22 attached to one end side of the rotating body 5, and the flange 22B is sandwiched by the bolt head 10 and the flange 7A. At this time, the other end of the bolt shaft portion 12 penetrates through the through hole 22C of the bearing member 22 mounted on the other end side of the rotating body 5 to the other end side from the flange 7B.

さらに、他端側の軸受部材２２から突き抜けたボルト軸部１２の他端を取付孔２０に通し、取付孔２０から突き抜けたボルト軸部１２の他端からナット１１を螺合していく。
これにより、回転阻止部４および回転体５は２つの軸受部材２２とともに被取付部１８に取り付けられる。 Further, the other end of the bolt shaft portion 12 penetrating from the bearing member 22 on the other end side is passed through the mounting hole 20, and the nut 11 is screwed from the other end of the bolt shaft portion 12 penetrating from the mounting hole 20.
As a result, the rotation blocking portion 4 and the rotating body 5 are attached to the attached portion 18 together with the two bearing members 22.

〔実施例１の電線敷設方法〕
実施例１の電線支持装置１を用いた電線敷設方法を、図面を用いて説明する。
実施例１の電線敷設方法は、次の送り出し工程、回転阻止工程および締結工程を備える。ここで、電線支持装置１は、電線２の敷設工事のときに、敷設ルートに搬入して据え付けられる。すなわち、電線支持装置１は、建物において、敷設ルートに沿った所定の箇所に装着部１９を装着することで据え付けられる。 [Wire laying method of Example 1]
An electric wire laying method using the electric wire support device 1 of Example 1 will be described with reference to the drawings.
The wire laying method according to the first embodiment includes the following feeding step, rotation blocking step, and fastening step. Here, the electric wire support device 1 is carried into a laying route and installed at the time of laying the electric wire 2. That is, the electric wire support device 1 is installed by mounting the mounting portion 19 at a predetermined location along the laying route in a building.

そして、送り出し工程では、電線支持装置１を利用して電線２を目的とする場所まで送り出す。すなわち、送り出し工程は、回転阻止部４により回転体５の回転を阻止せずに回転体５を回転自在とし、電線載置部３を介して電線２を送り出す工程である。つまり、回転自在となっている回転体５の円筒部６の外周面６Ａに電線２を載せ、回転体５を電線２の送り出しに応じて回転させることで、電線２を目的とする場所まで送り出す。そして、電線２を目的とする場所まで送り出した後、次の回転阻止工程に移行する。 Then, in the sending-out process, the wire 2 is sent to a target location by using the wire supporting device 1. That is, the feeding step is a step in which the rotation blocking unit 4 does not block the rotation of the rotating body 5 so that the rotating body 5 is rotatable and the wire 2 is fed through the wire mounting portion 3. In other words, the electric wire 2 is placed on the outer peripheral surface 6A of the cylindrical portion 6 of the rotatable body 5 and is rotated in accordance with the delivery of the electric wire 2, whereby the electric wire 2 is delivered to a desired location. .. And after sending out the electric wire 2 to the target place, it transfers to the following rotation prevention process.

回転阻止工程は、回転体５の外周面６Ａに電線２を載せた状態で、回転阻止部４により回転体５の回転を阻止する工程である。
すなわち、電線２を目的とする場所まで送り出した後、ナット１１の螺合を進めてナット１１を一端側に移動させる。これにより、回転体５は、軸受部材２２および被取付部１８を介してボルト頭部１０とナット１１により挟み込まれ、回転を阻止される。このため、電線２は、静止した回転体５の外周面６Ａに載った状態になる。 The rotation blocking step is a step of blocking the rotation of the rotating body 5 by the rotation blocking section 4 with the electric wire 2 placed on the outer peripheral surface 6A of the rotating body 5.
That is, after the electric wire 2 has been sent to the intended location, the screwing of the nut 11 is advanced to move the nut 11 to the one end side. As a result, the rotating body 5 is sandwiched between the bolt head 10 and the nut 11 via the bearing member 22 and the attached portion 18, and rotation is blocked. Therefore, the electric wire 2 is placed on the outer peripheral surface 6A of the stationary rotating body 5.

締結工程は、回転体５の回転を阻止した後、電線２を所定の締結具により回転体５に締結する工程である。締結具は、例えば、紐２４であり、電線２と円筒部６とを縛り付けるように結び目が形成される。 The fastening step is a step of fastening the electric wire 2 to the rotating body 5 with a predetermined fastener after blocking the rotation of the rotating body 5. The fastener is, for example, a string 24, and a knot is formed so as to bind the electric wire 2 and the cylindrical portion 6 together.

〔実施例１の効果〕
実施例１の電線支持装置１によれば、電線載置部３は、軸心の周囲に回転自在の回転体５を有して被取付部材１７に取り付けられ、回転体５の外周面６Ａに電線２が載るものである。また、回転阻止部４は、回転体５の回転を阻止する。
これにより、電線敷設工事における送出支援器の撤去や電線支持専用の装置の据え付けの煩雑さを解消することができる。 [Effect of Example 1]
According to the electric wire support device 1 of the first embodiment, the electric wire mounting portion 3 has the rotatable body 5 rotatable around the axis and is attached to the mounted member 17, and the outer peripheral surface 6A of the rotatable body 5 is provided with the rotatable body 5. The electric wire 2 is mounted on it. Further, the rotation blocking unit 4 blocks the rotation of the rotating body 5.
As a result, it is possible to eliminate the complexity of removing the delivery support device and installing a device dedicated to supporting the electric wire in the electric wire laying work.

すなわち、電線支持装置１によれば、回転体５を回転自在にしておくことにより、送出支援具として利用することができる。そして、電線２の送り出しを終えた後、回転阻止部４により回転体５の回転を阻止することで、引き続き、回転体５の外周面６Ａに電線２を載せておくことができるので、電線２の支持に利用することができる。 That is, according to the electric wire support device 1, it is possible to use the electric wire support device 1 as a delivery support tool by making the rotating body 5 rotatable. Then, after the feeding of the electric wire 2 is completed, the rotation preventing portion 4 prevents the rotation of the rotating body 5, so that the electric wire 2 can be continuously placed on the outer peripheral surface 6A of the rotating body 5. Can be used to support

このため、送出支援具として利用した電線支持装置１を撤去して、別の電線支持専用の装置を据え付ける必要がなくなる。
以上により、電線敷設工事における送出支援具の撤去や電線支持専用の装置の据え付けの煩雑さを解消することができる。 Therefore, it is not necessary to remove the wire support device 1 used as the delivery support tool and install another device dedicated to support the wire.
As described above, it is possible to eliminate the complexity of removing the delivery support tool and installing the device dedicated to supporting the electric wire in the electric wire laying work.

また、回転体５の外周面６Ａは絶縁素材からなる。
これにより、万が一、電線２の被覆が傷ついても漏電の可能性を大幅に低減することができる。 The outer peripheral surface 6A of the rotating body 5 is made of an insulating material.
Thereby, even if the coating of the electric wire 2 is damaged, the possibility of electric leakage can be significantly reduced.

また、電線載置部３は、複数の回転体５を有し、これら複数の回転体５は、軸心が互いに平行、かつ、軸心に垂直な方向に並ぶ軸垂直列１６を形成している。
これにより、複数の電線２を建物の同一箇所で送り出したり支持したりすることができるので、例えば、軸垂直列１６の１つの段の回転体５に、電線２を送り出して載置した後、別の段の回転体５に、電線２を送り出して載置することができる。 Further, the wire mounting portion 3 has a plurality of rotating bodies 5, and the plurality of rotating bodies 5 form an axis vertical row 16 in which axes are parallel to each other and are arranged in a direction perpendicular to the axes. There is.
Thereby, since the plurality of electric wires 2 can be sent out and supported at the same place in the building, for example, after the electric wires 2 are sent out and placed on the rotating body 5 of one stage of the vertical axis row 16, The electric wire 2 can be sent out and placed on the rotating body 5 in another stage.

このため、建物の同一箇所において電線２を送り出すたびに、新規に装置を据え付ける必要がないので、作業の煩雑さを更に低減することができる。
さらに、軸垂直列１６の段ごとにフランジ７Ａ、７Ｂの間隔、つまり、円筒部６の長さを変えることで、段ごとに異なる径の電線２を支持することができる。 For this reason, it is not necessary to newly install a device every time the electric wire 2 is sent out to the same place in the building, so that the complexity of the work can be further reduced.
Furthermore, by changing the distance between the flanges 7A and 7B for each step of the axis vertical row 16, that is, the length of the cylindrical portion 6, it is possible to support the electric wires 2 having different diameters for each step.

また、回転阻止部４は、ボルト頭部１０、および、ナット１１を第１、第２規制部１０、１１として利用するものであり、ボルト頭部１０およびナット１１により、回転体５を挟むことで回転体５の回転を阻止する。 The rotation blocking unit 4 uses the bolt head 10 and the nut 11 as the first and second restricting units 10 and 11. The bolt head 10 and the nut 11 sandwich the rotating body 5. The rotation of the rotating body 5 is blocked by.

これにより、例えば、電線２を送り出すときのように、回転体５を回転自在の状態で利用するときに、ボルト頭部１０およびナット１１により、回転体５が軸方向に移動して脱落等するのを防止することができる。また、ボルト頭部１０およびナット１１により回転体５を挟んで回転体５の回転を阻止することができるので、回転体５の回転阻止のために、別途、部品を追加する必要がなくなる。 As a result, when the rotating body 5 is used in a rotatable state, for example, when the electric wire 2 is sent out, the bolt head 10 and the nut 11 cause the rotating body 5 to move in the axial direction and fall off. Can be prevented. Further, the rotation of the rotating body 5 can be prevented by sandwiching the rotating body 5 with the bolt head 10 and the nut 11, so that it is not necessary to add a separate component to prevent the rotating body 5 from rotating.

また、回転阻止部４は、ボルト軸部１２に設けられた雄ネジ、ナット１１の雌ネジを、それぞれ第１、第２ネジ部１３、１４として利用するものであり、ボルト軸部１２を回転体５の内周８に通し、内周８から突き出たボルト軸部１２にナット１１を螺合させている。そして、ボルト軸部１２とナット１１との螺合によりボルト頭部１０とナット１１とを近付けることで回転体５を挟む。
これにより、ネジの螺合を利用して回転体５の回転を阻止することができる。 Further, the rotation blocking portion 4 uses the male screw provided on the bolt shaft portion 12 and the female screw of the nut 11 as the first and second screw portions 13 and 14, respectively, and rotates the bolt shaft portion 12. A nut 11 is screwed into a bolt shaft portion 12 protruding from the inner circumference 8 through the inner circumference 8 of the body 5. Then, the rotating body 5 is sandwiched by bringing the bolt head portion 10 and the nut 11 close to each other by screwing the bolt shaft portion 12 and the nut 11 together.
Thereby, the rotation of the rotating body 5 can be prevented by utilizing the screw engagement.

また、実施例１の電線敷設方法は、次の送出工程および回転阻止工程を備える。まず、送出工程では、回転阻止部４により回転体５の回転を阻止せずに回転体５を回転自在として、電線載置部３を介して電線２を送り出す。次に、回転阻止工程では、回転体５の外周面６Ａに電線２を載せた状態で、回転阻止部４により回転体５の回転を阻止する。 Further, the electric wire laying method of the first embodiment includes the following feeding step and rotation blocking step. First, in the sending step, the rotation preventing unit 4 does not prevent the rotation of the rotating body 5 and the rotating body 5 is rotatable, and the electric wire 2 is sent out through the electric wire placing section 3. Next, in the rotation blocking step, the rotation blocking portion 4 blocks the rotation of the rotating body 5 with the electric wire 2 placed on the outer peripheral surface 6A of the rotating body 5.

これにより、電線２を目的とする場所まで送り出した後、回転体５の回転が阻止されるので、電線２を、静止した回転体５の外周面６Ａに載せておくことができる。このため、電線敷設工事における送出支援具の撤去や電線支持専用の装置の据え付けの煩雑さを解消することができる。 As a result, the rotation of the rotating body 5 is prevented after the electric wire 2 is sent to the intended place, so that the electric wire 2 can be placed on the outer peripheral surface 6A of the stationary rotating body 5. Therefore, it is possible to eliminate the complexity of removing the delivery support tool and installing a device dedicated to supporting the electric wire in the electric wire laying work.

すなわち、送出工程において、回転体５を回転自在にしておくことにより、電線支持装置１を送出支援具として利用することができる。そして、電線２の送り出しを終えた後、回転阻止部４により回転体５の回転を阻止することで、引き続き、静止した回転体５の外周面６Ａに電線２を載せておくことができるので、電線支持装置１を電線２の支持に利用することができる。 That is, in the sending step, the electric wire support device 1 can be used as a sending assist tool by allowing the rotating body 5 to rotate. Then, after the feeding of the electric wire 2 is completed, the rotation preventing portion 4 prevents the rotation of the rotating body 5, so that the electric wire 2 can be placed on the outer peripheral surface 6A of the stationary rotating body 5 continuously. The wire support device 1 can be used to support the wire 2.

このため、送出支援具として利用した電線支持装置１を撤去して、別の電線支持専用の装置を据え付ける必要がなくなる。
以上により、電線敷設工事における送出支援具の撤去や電線支持専用の装置の据え付けの煩雑さを解消することができる。 Therefore, it is not necessary to remove the wire support device 1 used as the delivery support tool and install another device dedicated to support the wire.
As described above, it is possible to eliminate the complexity of removing the delivery support tool and installing the device dedicated to supporting the electric wire in the electric wire laying work.

さらに、電線敷設方法は、次の締結工程を備える。すなわち、締結工程では、回転体５の回転を阻止した後、電線２を紐２４により縛って回転体５に締結する。
これにより、敷設後の電線２が変位するのを確実に防止することができる。 Furthermore, the wire laying method includes the following fastening step. That is, in the fastening step, after the rotation of the rotating body 5 is blocked, the electric wire 2 is tied with the string 24 and fastened to the rotating body 5.
As a result, it is possible to reliably prevent the electric wire 2 that has been laid from being displaced.
