Problems solved by technology

[0007] The invention solves the defect in the prior art that only prestressed tendons are stretched and controlled, resulting in uncertain factors in the final stretching results of different components, and invents a prestressed stretching control system and control method. In addition to the tension control, it is also necessary to control the components in the prestress tension to ensure that the final prestress tension meets the requirements of different components
[0008] The invention also solves the defects of poor tension synchronization at both ends of the component in the prior art, and the inaccurate tension control makes the prestress tension not meet the requirements, and invents a prestress tension control system and control method, and the two ends of the component are synchronized Tensioning, the same tensioning force is output, and the elongation of the prestressed tendon is monitored by the displacement sensor, and finally summarized and fed back to each tensioning part on the terminal machine

Abstract

The invention relates to a prestressed tension control system and a control method, so as to solve the defect that tension control is only carried out on prestressed reinforcement in the prior art and therefore, uncertain factors exist in final tension results of different components. The prestressed tension control system comprises two symmetrical independent tension parts, a front-end controller connected with the tension parts and controlling the tension parts and a system host computer in wireless data exchange with the front-end controller. The tension parts are connected with oil pressure sensors and displacement sensors. The system also comprises camber measurement displacement sensors for monitoring cambers of components. The camber measurement displacement sensor can monitor camber changes of the components in the case of component prestressed tension, and therefore, different kinds of tension can be ensured to in a state of control on deformation of the components, tension changes caused by difference between individuals of different components can be avoided, and through monitoring cambers of the components, the final result of the component prestressed tension can be prevented from being influenced due to reasons of component individual differences.

Description

technical field [0001] The invention relates to a control system, in particular to a prestress tension control system and control method, which is controlled by the tension device itself during the tension process, and is also controlled by the deformation of the component after being stretched. Background technique [0002] In bridge construction and other aspects, prestressed tensioning of concrete components is widely used. This process can not only effectively reduce the amount of concrete used, but also reduce energy consumption and pollution. [0003] Prestressed tension is to add tension in the component in advance, so that the prestressed tensioned component bears the tensile stress, and then makes it produce a certain deformation to cope with the load on the steel structure itself. Before the engineering structural components are subjected to external loads, pre-compressive stress is applied to the steel strands in the tension module to improve the bending resistanc...
