Description

  The present invention relates to a bracelet reinforcing band. In particular, the present invention relates to a bracelet reinforcing band that can be used for a holding armband or a non-hole armor without a band hole.

  Conventionally, when wiring an electric wire between electric poles, it is common to attach a metal arm to the electric pole, provide an insulator and a strap on the arm metal, and hold and wire the electric wire to the electric pole via the insulator and the strap. is there.

  For example, in the case of horizontal wiring in which a plurality of electric wires are arranged horizontally, one arm is attached to the utility pole so that it is horizontal with respect to the ground, and each wire is supported at both ends or the center of the arm. An insulator and a strap are provided, and an electric wire is fastened and wired through the insulator and the strap. In addition, when holding a large-diameter wire whose cross-sectional area is larger than a predetermined size, a single arm is insufficient in strength and the like, and a holding arm that combines two arms is used. .

  Here, the holding arm is arranged at a position facing the one arm attached to the utility pole at a position opposite to the one with the utility pole sandwiched between the utility poles. In the section, the arm brackets are connected by bolts or the like.

  By the way, in the conventional arm metal, the arm metal fastening bolt is passed through the band hole provided in the metal arm, and this is screwed into the bolt hole provided in the power pole, thereby fixing the metal arm to the power pole. There is something that is.

  Such a brace usually bears only a light load due to its own weight, etc., but in the event of a strong wind, especially when typhoon hits it, it interrupts a large load due to wind and rain in addition to its own weight. May be burdensome. This large load generates a tensile force on the arm metal, and this tensile force acts as a moment from the connecting portion of the utility pole and the arm metal to the fixing point of the electric wire. As a result, even when the load acting on both ends of the arm metal due to the weight of the electric wire is relatively small, the force acting on the base of the arm metal may increase. There was a risk that this would cause a situation in which the arm metal fastening bolt would come off and the arm metal would fall off.

  As a means for avoiding such a situation, conventionally, an adjustment-type U-shaped band is attached to the above-described arm metal to reinforce the connection state between the arm metal and the utility pole. Here, the adjustable U-shaped band is a member in which a male screw portion is provided at the tip of a bar that is curved in a substantially U shape. The bracelet has a male screw part provided at the tip of the U-shaped band penetrating through a band hole provided in the bracelet with the curved part of the U-shaped band wound around a part of the outer periphery of the utility pole. The male screw part that penetrates the band hole is tightened with a nut and tightened to reinforce the connection with the utility pole.

  However, since the U-shaped band as described above is used by directly penetrating the male screw portion into the band hole provided in the arm metal, it cannot be used for the arm metal having no band hole. Even if the arm has a band hole, a part of the U band interferes with the arm when the arm is provided facing the electric pole like the above-mentioned holding arm. Therefore could not be used.

Therefore, in the past, for hugging and non-holed bracelets, instead of reinforcing the bracelets, a means of attaching an arm tieless band to the utility pole and fixing the bracelet to the utility pole using this arm tieless band has been used. (For example, refer to Patent Document 1).
Japanese Utility Model Publication No. 06-74030

  However, the arm tieless band as described above has to be operated with the arm metal removed at the time of installation or replacement. In other words, in order to remove the brace, it was necessary to temporarily work out the part related to the utility pole. As a result, there is a problem that a temporary power outage reduction work based on the power outage work is required and the work cost increases. In addition, since this work requires a sufficient work time for installation or replacement work, the time work efficiency is poor as compared with the case where the brace is reinforced. In addition, the construction content associated therewith may be complicated. Therefore, there is a need for an armband reinforcement band that can be used as a holding armor or a non-hole armband without replacing it with an arm tieless band that requires power outage work and that can easily reinforce the armband. It was rare.

  The present invention has been made in view of the above-mentioned problems, can be used for a holding arm and a non-hole arm, and does not require power outage work in installation or replacement work, An object of the present invention is to provide a band for reinforcing a bracelet that can easily reinforce a bracelet easily.
