Description

  The present invention relates to a lifting pipe support fitting used for supporting an outdoor cable protection lifting pipe on a utility pole or the like when an outdoor cable such as a communication line is vertically attached to a utility pole or the like.

  To attach the cable protection lifting pipe vertically to the utility pole, use a steel support band with a length that can be wound around the utility pole and the lifting pipe, and connect both ends of the support band with fasteners. The tightening method is generally known. In this method, the utility pole and the lifting pipe are strongly joined and no gap can exist between them, so if a utility pole sign plate or the like is attached later, the power pole and the lifting pipe are forcibly pushed between the utility pole and the lifting pipe. There was a problem in terms of workability and appearance because it was installed around the utility pole and the pull-up pipe even if the gap was created or attached, even if the appearance of the utility pole sign board deteriorated. Moreover, since the raising pipe is attached to the utility pole at two places, upper and lower, two support bands are required for each raising pipe.

On the other hand, as a support bracket for a utility pole lifting pipe that can solve such a problem related to the gap, a structure in which a neck portion is formed between the surrounding part of the utility pole and the surrounding part of the lifting pipe has been publicly known. ing. This publicly known support pole for the electric pole lifting pipe is constituted by a connectable iron support band in which both the surrounding parts can be tightened simultaneously by bolts and nuts attached to the neck part, Due to the presence of the neck portion, a gap can exist between the utility pole and the pulling pipe.

  The above-mentioned publicly known lifting pole support bracket for electric poles has solved the gap, but it is supported only by a simple support band that two lifting brackets are required for each lifting pipe attached to the utility pole. It is the same as that. By the way, usually, at most three lifting pipes are attached to one utility pole. If three rising pipes are attached to one utility pole, six support brackets are attached to one utility pole. It became necessary, and it took time to perform the mounting work in combination with the tightening operation of each support bracket, and improvement in terms of workability could not be expected.

  The present invention solves such a problem, and an object of the present invention is to provide a lifting pipe support fitting capable of detachably attaching about three pieces to one support band wound around a utility pole and fastened. Is to provide. That is, the lifting pipe support metal fitting of the present invention is attached to each of the support bands (conventional simple support bands used for this kind of support work) mounted at two places on the upper and lower sides of the utility pole. Each of the sets of support fittings can support the lifting pipe in a state where there is a gap between the support poles.

  In order to achieve the above-mentioned object, the lifting pipe support fitting according to the present invention is characterized in that the right and left sides have both free ends of the fastening band for attaching the lifting pipe so that the fastening portions can be tightened, and the front side Is constituted by a metal fitting body provided with an insertion plate portion that can be inserted between a utility pole and a support band wound around the utility pole, and a fastening band thereof. In this basic configuration, the metal fitting body is formed by pressing a single metal plate (generally an iron plate) that has been cut off.

  In the configuration of the present invention, the left and right fitting portions are provided with side plate portions provided on the left and right sides with a gap between the upper plate portion and the rear plate portion of the metal fitting body. In addition, the insertion plate portion is formed so that the front plate portion apparently hangs forward and the lower half protrudes from the side plate portion with the portions near the side plate portions cut off. ing. Then, a tightening bolt for freely tightening both free end portions of the tightening band is fitted between the left and right side plate portions so that the side plate portion can be relatively rotated with the side plate portion, and the nut screwed to the tightening bolt is tightened. Thus, the right and left side plate portions are pressed in a direction approaching each other, and the tightening band can be tightened.

  Both free ends of the fastening band are bent in a state of being opposed to each other, and are formed in a downward U-shaped fitting portion that can be loosely fitted onto the fastening screw. Stabilizing seats that protrude from the left and right edges of the insertion plate part in a front-opening manner and come into contact with the utility pole when the mounting of the support bracket is completed, and the lower part of the insertion plate part is slightly inclined backward. Thus, it is preferable to carry out the function of preventing contact from coming into contact with the support band, whereby the mounting state of the support fitting is firmly stabilized.

  If the insertion plate part is inserted between the utility pole and the support band that is wound loosely around the utility pole, and the support band is fastened to the utility pole, the mounting state of the support bracket is firmly determined, and the lifting pipe to the utility pole This support operation can be easily and safely performed by tightening the tightening band attached to the support bracket. In addition, since the support bracket can be practically attached to one support band, it can be supported even in the case where, for example, three lifting pipes are supported on one utility pole. Since only two bands are used for both the upper and lower positions of the band, it is convenient for supporting work especially at the position of the high place, and of course, it is possible to reduce dangerous labor, and workability can be greatly improved, and Also good from an aesthetic point of view.
