High-bending-moment carbon-fiber reinforced concrete pole and manufacturing method thereof

Abstract

Disclosed are a high-bending-moment carbon-fiber reinforced concrete pole and a manufacturing method thereof. Carbon-fiber ropes or carbon-fiber rope and concrete together constitute a pole framework, and high-grade concrete is poured to the framework, so that the high-bending-moment carbon-fiber reinforced concrete pole is made. The manufacturing method includes fixing and tightening the carbon-fiber ropes to an upper pier head and a lower pier head of a steel mold through wedge-hinged C-shaped clamps, pouring the high-grade concrete by a conventional reinforced concrete pole centrifugation process, performing steam curing, and finally forming the full-carbon-fiber concrete pole or carbon-fiber reinforced concrete pole. The pole manufactured by the method has all advantages of the conventional prefabricated reinforced concrete pole, and further, steel can be saved greatly while cost can be lowered, and the pole body has high intensity and high bending moment. On the premise of not increasing manufacturing cost or increasing pole diameter, limitation to height and diameter of the conventional prefabricated concrete pole is broken through, the defect of the design depending on selecting high-intensity steel and increasing steel usage is overcome, and concrete poles with larger diameter and height can be produced by the manufacturing method.

Description

technical field [0001] The invention relates to a concrete wire rod and a manufacturing method, in particular to a concrete wire rod for erecting lines and a manufacturing method. Background technique [0002] At present, reinforced concrete poles have the advantages of low price, less land occupation, simple process, and convenient installation. There are prestressed poles and non-prestressed ordinary poles. The design, production and application are very mature. They are widely used in electric power, Communication, municipal and other overhead occasions. However, the biggest disadvantage of reinforced concrete poles is that they are easy to break. In addition, if the production process is a little careless, the internal steel bars are prone to rust. Once rusted, the steel bars and concrete will be separated, causing great hidden dangers.

Problems solved by technology

However, the biggest disadvantage of reinforced concrete poles is that they are easy to break. In addition, if the production process is a little careless, the internal steel bars are prone to rust. Once rusted, the steel bars and concrete will separate, causing great hidden dangers.

Furthermore, the material and structure have natural restrictions on its height and diameter, which can only be compensated by selecting higher-strength steel and increasing the amount of steel used in the design, which will greatly increase the manufacturing cost and increase the manufacturing cost. , as the rod diameter increases, the weight of the wire rod also increases, which brings certain difficulties to transportation and installation
