Abstract

The invention discloses a prestressed tension tooling, which comprises a stool foot plate and a tension plate; a tension head connected with an oil cylinder is arranged at the center of the stool foot plate; and the oil cylinder is connected with a control system; A number of grooves; supporting columns are movable in the grooves; the tensioning plate is located between the supporting columns, and there is a limit groove at the center of the stool plate for the limit column to engage; the edge of the tensioning plate is provided with at least Four top screw rods; and a number of heading pins are arranged on the surface of the tensioning plate adjacent to the stool foot plate. The device can effectively stretch the steel bars in the electric pole, which is the pre-tensioning in the prestressed construction.

Description

technical field [0001] The invention belongs to the technical field of electric pole preparation, and in particular relates to a prestressed tension tooling. Background technique [0002] In recent years, the development of the electric power industry has become an important part of determining the growth of the national economy, and the electric pole is a bridge for electricity, allowing electricity to be transported to various places. With the development of science and technology, the requirements for electric poles are getting higher and higher, and Frequent electric pole incidents have attracted more and more attention. [0003] Electric poles are mainly divided into prestressed electric poles, non-prestressed electric poles and partially prestressed electric poles. Prestressed construction is a form of building structure to save steel and reduce the structure's own weight. Prestressed poles and partially prestressed poles add a part of the compressive stress load to t...
