Anti-freezing concrete pole with high collision resistance

Abstract

The invention provides a high-collision-resistance anti-freezing concrete pole, and relates to the technical field of power supply and transmission. The anti-freezing concrete pole comprises connecting pieces, wherein the connecting pieces are divided into upper connecting pieces and lower connecting pieces, the upper connecting pieces are connected to the top ends of main steel bars, the lower connecting pieces are connected to the bottom ends of the main steel bars, and the top side of one upper connecting piece is connected with the bottom side of the other lower connecting piece; a steel bar frame connected to the outer sides of the main steel bars; and foam strips, wherein the number of the foam strips is six, and the upper ends and the lower ends of the foam strips are connected with the upper connecting pieces and the lower connecting pieces correspondingly. The self weight of the concrete pole is reduced through the foam strips, meanwhile, the concrete pole is subjected to anti-freezing and heat preservation, the thermal expansion and cold contraction coefficient of the concrete pole is reduced, and the concrete pole is prevented from cracking. The problems that a traditional concrete electric pole is poor in anti-freezing performance, after being used for a period of time, the concrete electric pole is prone to being affected by heat expansion and cold contraction of the outside air temperature, many cracks are generated, and the anti-collision strength of the concrete electric pole is affected are solved.

Description

technical field [0001] The invention relates to the technical field of power supply and transmission, in particular to a high-collision-resistant and frost-resistant concrete pole. Background technique [0002] Power poles are bridges for electricity, allowing electricity to be transported to various places. Common poles include wooden poles and cement poles. They are of different heights, stand in the plains and mountains, and spread around people. There are many types of poles, such as: concrete poles, that is, poles made of concrete. [0003] However, the current traditional concrete poles have poor frost resistance. After a period of use, the concrete poles are easily affected by the thermal expansion and contraction of the outside air temperature, resulting in many cracks, which affect the impact strength of the concrete poles, and have a single function. When it is necessary to connect buried cables, a cable fixing frame needs to be installed separately, and the const...

[0003] However, the current traditional concrete poles have poor frost resistance. After a period of use, the concrete poles are easily affected by the thermal expansion and contraction of the outside air temperature, resulting in many cracks, which affect the impact strength of the concrete poles, and have a single function. When it is necessary to connect buried cables, additional cable fixing brackets need to be installed, which makes the construction process more cumbersome
