Automatic control system and method of pre-tensioning prestress construction

Abstract

The invention relates to the technical field of prefabricated beam construction, in particular to an automatic control system and method of pre-tensioning prestress construction. The automatic control system comprises an automatic control center and a power system. The automatic control center is connected with a monitoring device and a control device. The monitoring device comprises a component used for monitoring the steel strand tensioning parameters and the pressure of the power system. The automatic control center is further provided with a signal receiving device and a micro processing module. An original data signal is received by the signal receiving device, analyzed and processed by the micro processing module, converted into a control signal and transmitted to the control device. The tensioning process is completed through control of the control device to the power system. By the adoption of the automatic control system, the problems that according to manual control, numerical reading is inaccurate, and the tensioning stress is difficult to control accurately are solved, the tensioning stress is well controlled, the tensioning process of steel strands meets the technological requirements, the quality of a prefabricated beam is improved, and standard production of products is also promoted.

Description

technical field [0001] The invention relates to the technical field of prefabricated beam construction, in particular to an automatic control system and method for pretensioning prestressed construction. Background technique [0002] Pretensioning method is a method of pre-stressing concrete members during the prefabrication process to improve the performance of members in order to improve the crack resistance of reinforced concrete members and avoid premature cracks in reinforced concrete members. Usually, the method of tensioning steel bars before pouring concrete is also known as pretensioning, and it plays an important role in engineering construction. [0003] In the production of prefabricated beams, the process of pretensioning and prestressing has a great effect on improving the structure and performance of the beam body. First, the fixed steel strands are stretched and fixed before pouring concrete, and the tensioned fixed steel strands are temporarily anchored. Th...

Problems solved by technology

[0005] The purpose of the present invention is to: in the process of pretensioning prestressing construction, due to the relatively rough method of manually monitoring the tension and manually controlling the size of the prestress, there are inaccurate readings in each tensioning process, which is difficult to be accurate Control the tension stress, which leads to problems that cannot be standardized production, tension steel strands are not in place, and affect the quality of prefabricated beams. An automatic control method for pre-tensioning prestressed construction is provided. This method introduces automatic The control system, through the automatic control system and method of pre-tensioning prestressed construction, can accurately and effectively monitor the tension parameters of the steel strand, such as the tension amount, and the applied tension stress can be better controlled, so that the steel strand The unique tensioning process meets the manufacturability requirements, improves the quality of prefabricated beams, and also promotes the standardized production of products
