Intelligent pre-stressed stretching equipment, spot intelligent tensioning bridge, railway building tensioning machine

Intelligent tensioning refers to the use of computer intelligent control technology, without relying on manual control by workers, to complete the tensioning construction of steel strands through automatic operation of instruments.

In today's bridge and road construction, prestressed construction is widely used, and the key process of tensioning directly affects the durability of the structure. However, traditional tensioning construction relies solely on manual operation by construction personnel based on experience, with a high error rate, which cannot guarantee the quality of prestressed construction. Many bridges have been reinforced in advance due to unqualified prestressed construction, and in severe cases, they even suddenly collapse, causing huge losses of life and property to society.

Due to the high accuracy and stability of intelligent systems, intelligent tensioning technology can completely eliminate human interference and effectively ensure the quality of prestressed tensioning construction. It is currently a technology in the field of prestressed tensioning in China.

Intelligent tensioning system usage:

Mainly used in various pre tensioning or post tensioning prestressed construction methods such as bridges, tunnels, hydroelectric dams, water conservancy aqueducts, buildings, steel components, etc.

Main functions:

1. The intelligent tensioning system can accurately control the error of the prestressing force applied during the construction process, reducing the error range from ± 15% of traditional tensioning to ± 1%, solving diseases such as bridge cracking caused by insufficient or excessive prestressing force, ensuring structural safety, improving durability, extending service life, and reducing maintenance costs.

2. Realized intelligent control of the tensioning process, unaffected by human and environmental factors; Control the synchronization of symmetrical tensioning, pause points, loading rate, load holding time, etc. The tensioning process elements fully comply with the requirements of bridge construction technical specifications. By standardizing the tensioning process, the harm caused by asymmetric tensioning on the structure, such as distortion, has been eliminated, greatly reducing the loss of prestress during the tensioning process, and ensuring that effective prestress meets design requirements.

3. Able to accurately and real-time measure and review the elongation of prestressed reinforcement, and further control the quality of prestressed tension through elongation review. 4. The tensioning data is automatically recorded, which eliminates the possibility of artificial falsification of quality data and allows for true quality traceability.

5. Implement remote monitoring function, facilitate quality management, and improve management efficiency.
