Description

Technical Field

[0001] The present invention relates to the technical field of prestressed tensioning of continuous beams of large-scale high-speed railway station buildings, and in particular to a prestressed intelligent tensioning integrated trolley for large-scale high-speed railway station buildings. Background Art

[0002] The construction of high-speed railways and highways is inseparable from continuous beams. Continuous beams are connected by several continuous components in the span, and play a vital role in the construction of high-speed railways and highways. At present, bridges and tunnels account for more than 90% of my country's high-speed railway construction. As an important form of high-speed railway bridges, the construction of continuous beams plays an important role in ensuring the quality and safety of railway bridges. With the gradual popularization of ballastless track technology, prestressed concrete continuous beams have been widely used. After the concrete reaches the predetermined strength, the internal prestressed steel bars are tensioned to generate pressure on the concrete, increase the bearing capacity and deformation control of the bridge, strictly implement the tensioning process in accordance with the specifications, and conduct tensioning force and steel deformation detection after reaching the predetermined tensioning force. The detection results are recorded and analyzed, etc. Prestressing operations are an important part of quality control.

[0003] However, in the process of traditional prestressing of continuous beams, there are problems such as low accuracy of detection results causing detection deviation, insufficient intelligence caused by the inconsistency of the tensioning and measurement process, the inability to quickly compare the current steel strand elongation value with the current theoretical elongation value, which causes the uncontrollable abnormal tensioning work situation, and the inability to automatically stop work and automatically alarm when the work is abnormal or the tensioning data is out of tolerance.
