Connection structure of feeder line holder and circular concrete pole

Abstract

The invention discloses a connection structure of a feeder line holder and a circular concrete pole. The technical scheme is that the connection structure of the feeder line holder and the circular concrete pole comprises the circular concrete pole, a feeder line holder connection frame and the like and is characterized in that more than two feeder line holder embedded nuts are arranged in the circular concrete pole, one side of connection angle steel is connected with the feeder line holder embedded nuts through connection bolts, and the other side of the connection angle steel is connected with feeder line holder vertical angle steel of the feeder line holder. The connection structure of the feeder line holder and the circular concrete pole has the advantages that the installation on construction sites is fast and convenient, and the operation process is flexible, easy and safe. The feeder line holder of a reinforced concrete structure of a communications tower effectively achieves vertical installing and fastening of cable feeder lines, reasonable wiring and branching for moving transmission feeder lines are ensured, and a tower body is attractive and neat in appearance, and good in safety and durability.

Description

technical field [0001] The invention belongs to the technical field of communication facilities, and in particular relates to the improvement of the connection structure between a feeder frame and an annular concrete pole. Background technique [0002] With the continuous high-speed development of modern power grid construction and communication technology, the height of towers is increasing, and the bending strength is increasing. Ring-shaped concrete poles with different heights, different diameters, different wind resistance levels, and different bending strengths are widely used. During the construction process, the upper and lower cable brackets need to be installed on the terminal pole of the power line. Each base of the communication tower has an upper and lower cable feeder, so a feeder fixing device must be installed to prevent unsafe factors caused by the swing of the feeder in strong winds. The traditional fixing method of the communication tower feeder frame is t...

Problems solved by technology

The disadvantage of the existing technology is that the construction and installation of this method is difficult, and there are unsafe factors during installation. Because there are too many connecting hoops to be installed on the rod body, the rod body is messy and messy, and the amount of steel used is large, which affects the construction progress.

Another thing is that the hoop of the ladder is exposed on the outer surface of the concrete pole. During the later operation of the line, the hoop is easily corroded, which can greatly reduce the connection strength of the feeder frame, and the personal safety of the maintenance personnel cannot be guaranteed in the future maintenance work of the line.
