Concrete electric pole production method

Abstract

The invention provides a concrete electric pole production method. The concrete electric pole production method comprises the following steps of: bundling, welding and fixing non-prestressed main reinforcement and reinforcing bars to form a reinforcement cage; welding a section of a high-strength wire at one end of the reinforcement cage, and heading; performing wire-drawing on all reinforcing steel bars at the second end of the reinforcement cage, and applying pre-stress; placing the reinforcement cage applied with pre-stress into a mould, pouring the concrete, and locking the mould; puttingthe locking mould into centrifugal equipment, and performing centrifugal solidification; putting the centrifuged mould into a steam chamber, performing high-temperature curing and de-molding to obtainan electric pole. Compared with a mode of applying pre-stress by the pre-stressed concrete in the prior art, the concrete electric pole production method only needs once process, so that the processcost is reduced; and moreover, during wire drawing, only one section of high-strength wire is needed, so that the cost is lower, and the process is simpler in comparison with a state that steel wiresof the current pre-stressed reinforcement cage are high-strength wires.

Description

technical field [0001] The invention relates to the technical field of concrete electric poles. More specifically, it relates to a method for producing concrete poles. Background technique [0002] The prestressed concrete structure is to apply pressure to the structure before it bears the load, so that the internal force of the concrete in the tension area when the external load acts produces compressive stress, which is used to offset or reduce the tensile stress generated by the external load, so that the structure Under normal use, no cracks or cracks occur relatively late. The degree to which the prestressed concrete is applied to the prestressed concrete is called the prestressed degree. According to the principal stress state under any load combination, prestressed concrete can be divided into three categories: full prestress, limited (limit) prestress, and partial prestress. At present, due to the rising cost of raw materials, the cost of raw materials for concret...

Problems solved by technology

At present, due to the rising cost of raw materials, the cost of raw materials for concrete poles continues to rise. In order to reduce the cost of raw materials, it is necessary to apply prestress to the steel bars, so that the deflection of the steel bars is lower. However, in the current method, the steel wires in the steel bar skeleton are all high-strength Therefore, it is necessary to provide a new production method for concrete poles to reduce the production cost while ensuring that the deflection and crack width in the mechanical test are lower than the national standard and meet the demand
