Accurate application Features of tension
The intelligent tensioning system can precisely control the prestressing force applied by the jack and control the error range to ± 1%, which reduces the risk of cracking and dashing due to the insufficient prestressing or overburden. It is helpful to ensure the safety of the structure, Improve durability, extend service life, reduce maintenance costs.Accurate measurement and timely review of the amount of extension.System sensor real-time acquisition of strand extension data, feedback to the computer, automatically calculate the amount of extension, timely check whether the extension of ± 6% range, to achieve a real "double control."Symmetrical synchronization tensioning a computer to control two or more jacks simultaneously, synchronous symmetrical tension, to achieve "multi-top synchronous tension" process, eliminating the symmetrical tension is not synchronized to the structure caused by the distortion and other hazards. Standard tension process, a key to complete the tension.It can realize the intelligent control of the tensioning process, and it is not affected by man-made and environmental factors. The control process points such as the stop point, the loading rate and the holding time are in full accord with the technical requirements of the bridge construction. By normalizing the tensioning process, the prestressing loss during the tensioning process is greatly reduced, and the effective prestressing performance is ensured.
