  The present invention will be described below based on the illustrated embodiments.

(Embodiment 1)
FIG. 1 is a front view (a) and a side view (b) showing a mark 1 for an indirect hot wire construction method according to this embodiment. This indirect hot wire construction mark 1 is a mark for indicating a mounting position of a sleeve cover or the like (object) to the distribution line (electric wire) P in the indirect hot wire construction method, and is entirely composed of an electrically insulating resin. The band-shaped body is provided with the indicator portion 2 and the attachment portion 3 integrally. In this embodiment, the entirety is formed in a substantially J-shape (substantially inverted J-shape when the attachment portion 3 is directed upward), and a portion that is curved in a substantially arc shape constitutes the attachment portion 3, and a portion that extends straight is formed. The sign part 2 is configured.

  The marking portion 2 is a portion that is gripped by the indirect hot wire tool 100 shown in FIG. 2, and with respect to the axis of the distribution line P in a state where the attachment portion 3 is attached to the distribution line P as described later. It is a part extending almost vertically. That is, the width, the length, and the thickness are set so that they are formed in a rectangular shape, are easily grasped by the Yatco 120 of the indirect hot wire tool 100, and can be visually confirmed from the outside.

  Here, the indirect hot wire tool 100 is a tool used in the indirect hot wire method in which work is performed in an energized state, that is, the work is performed without the operator being in direct contact with a high-voltage tension insulator or an electric device. This tool is generally configured as follows.

  That is, as shown in FIG. 2, the tool is a bar-like tool having a Ytco 120 disposed at the tip, and has a gripping tool main body 110 and a Yatco 120. The gripping tool main body 110 is an insulating rod, and a metal support 111 is attached to the upper end portion. On the upper part of the support 111, movable arms 112 and 113 constituting the Yatco 120 are supported so as to be swingable via a support pin (not shown). The movable arms 112 and 113 are supported at the upper end of the operation rod 114. It is connected to the part.

Then, by operating the lever 115 in the direction of the arrow F1, the first movable arm 112 and the second movable arm 113 (Yatco 120) are opened and closed (turned) in the direction of the arrow F2.

  The attachment portion 3 is a portion that is detachably attached to the distribution line P, and in this embodiment, the opening is formed in a substantially semicircular arc shape that faces downward. The inner diameter of the mounting portion 3 is set to be slightly larger than the outer diameter of the distribution line P, and is hung on the distribution line P. Further, an adhesive 31 for temporary fixing is applied to the inner surface 3 a of the attachment portion 3. The adhesive 31 can reliably hold the mark 1 for the indirect hot wire method while functioning as a mark, and the mark 1 for the indirect hot wire method can be relatively easily held by the indirect hot wire tool 100. The adhesive strength is set so that can be peeled off.

  The indicator part 2 is provided so as to extend from one end edge of the attaching part 3 along the tangent line of the attaching part 3 (arc), and the thicknesses of the indicator part 2 and the attaching part 3 are equal. Moreover, the marker part 2 and the attachment part 3 are colored and colored in a color that is different from the outer surface color of the distribution line P and that can be easily visually confirmed from the outside. For example, the indicator part 2 is colored green, and the attachment part 3 is colored red.

  Next, the usage method etc. of the mark 1 for indirect hot wire construction of such a structure are demonstrated.

  For example, as shown in FIG. 3, when the sleeve cover C is attached to the connection location (sleeve) after the cut distribution line P is connected with the sleeve, the end portion of the sleeve cover C should be located at the location (attachment position). The indirect hot wire construction mark 1 is attached in advance. That is, the marker part 2 is gripped by the YATCO 120 of the indirect hot wire tool 100, the attachment part 3 is hooked from above the distribution line P, and the adhesive 31 is adhered by pressing, thereby arranging the mark 1 for the indirect hot wire method. Attach to the attachment position of the electric wire P.

  Next, the sleeve cover C is disposed and attached using the mark 1 for the indirect hot wire method as a mark. That is, the sleeve cover C is disposed on the mark 1 for the indirect hot wire method so that one end of the sleeve cover C is positioned, and the sleeve cover C is fixed to the distribution line P. After that, when the indirect hot wire construction mark 1 is no longer needed, the indirect live wire tool 100 is used to grip the marking portion 2 and lift the mounting portion 3 from the distribution line P to make the indirect live wire construction mark. 1 is removed.

  As described above, according to the mark body 1 for the indirect live wire construction method, when the mark body 1 for the indirect live wire construction method is attached in advance to the attachment position of the sleeve cover C or the like to the distribution line P, the marking portion 2 is connected to the distribution line P. In addition, since the marker part 2 is colored in a color that can be visually confirmed from the outside, the mark 1 for the indirect hot wire construction method is a clear mark showing the mounting position on the distribution line P It becomes. For this reason, the attachment position of the object such as the sleeve cover C becomes clear, and the object can be easily and quickly attached to the appropriate position of the distribution line P.

  In addition, when a plurality of objects are arranged on the distribution line P, the indirect hot wire marking 1 is attached to all the attachment positions in advance, making it easy to grasp the arrangement and layout of the entire work object. It is possible to speed up the process and improve the finish.

  In addition, it is easy and quick just to hold the marking portion 2 with the indirect hot wire tool 100, hang (attach) the mounting portion 3 on the distribution line P, and lift the mounting portion 3 from the distribution line P. It is possible to attach or remove the mark body 1 for the indirect hot wire method. In addition, since the entire structure is simply formed in a substantially J shape, the indirect hot wire marking 1 can be manufactured easily and at low cost.

(Embodiment 2)
FIG. 4 is a front view (a) and a side view (b) showing the mark 10 for the indirect hot wire method according to this embodiment. This indirect hot wire marking 10 is different from the first embodiment in that the attachment portion 13 is wound around the distribution line P.

  The sign part 12 has the same configuration as that of the first embodiment, and is a rigid body formed in a rectangular shape. The attachment portion 13 extends straight from one end portion of the marker portion 12 and is made of an elastically deformable (having spring property) plate material. The attachment portion 13 is wound around the object by being applied to the object like a patchon band or a patchless breath. It is like that.

  That is, the attachment portion 13 extends straight when no external force is applied, and when the mounting portion 13 is shaken in the direction of arrow D in FIG. 4 and applied to the distribution line P from the straight extension state, as shown in FIG. Wrap around. Moreover, if the label | marker part 12 is pulled or the attachment part 13 is bent, the attachment part 13 will extend straight again and will remove | deviate from the distribution line P. FIG. Such an attaching part 13 may be comprised with a single material, and may be comprised with multiple materials. For example, a metal core material may be covered with a resin or rubber cover.

  Here, the length of the attachment portion 13 is such that the indirect hot wire method mark 10 is difficult to be removed when the mounting portion 13 is wound around the distribution line P, and the indirect hot wire method mark 10 is pulled when the marker portion 12 is pulled. Is set to be easy to come off. In addition, the marker portion 2 and the attachment portion 3 are colored and colored in the same manner as in the first embodiment.

  As described above, according to this embodiment, the attaching portion 13 is simply attached to the distribution line P by gripping the indicator portion 12 with the indirect hot wire tool 100 and swinging the attaching portion 13 from the straight extension state. The indirect hot wire mark 10 is wound around the distribution line P and attached to the distribution line P. In addition, the indirect hot wire marking 10 can be removed from the distribution line P simply by pulling the marking portion 12. Thus, the indirect hot wire mark 10 can be attached or removed easily and quickly.

  Moreover, since the adhesive 31 is not used, it can be used repeatedly without repainting the adhesive 31. Furthermore, during normal times (when not in use), the mounting portion 13 is extended straight, thereby facilitating storage, transportation, and carrying.

  Although the embodiment of the present invention has been described above, the specific configuration is not limited to the above embodiment, and even if there is a design change or the like without departing from the gist of the present invention, Included in the invention. For example, in Embodiment 1, instead of the adhesive 31, as shown in FIG. 6, a facing portion that extends from the other end edge of the mounting portion 3 (an edge on the side opposite to the marking portion 2) to face the marking portion 2. 4 may be provided. The facing portion 4 has the same width and thickness as the marker portion 2 and is shorter than the marker portion 2. And by attaching the attachment part 3 to the distribution line P, the distribution line P is pinched by the label | marker part 2 and the opposing part 4, and the mark body 1 for indirect hot wire construction becomes difficult to fall. Further, the distance H between the marking portion 2 and the facing portion 4 and the inner diameter of the mounting portion 3 are slightly smaller than the outer diameter of the distribution line P so that the distribution line P is sandwiched and held between the marking portion 2 and the facing portion 4. As a result, it is possible to prevent or suppress the indirect hot wire mark 1 from being dropped or positioned.

  In the first and second embodiments, the marking portions 2 and 12 and the attachment portions 3 and 13 are colored in different colors. However, they may be colored in the same color, or only the marking portions 2 and 12 are arranged. You may color in the color different from the electric wire P. FIG. Further, it may be colored with a fluorescent color so that it can be easily seen at night.
