Stress Anchorages System of YJM
Introduction
YJM prestressed anchorage system is mainly used for the prestressed concrete structures and components in the construction of pre-tensioned and post-tensioned.
The system is currently dominated in the field of prestressed tension anchorage systems.
A typical stress anchoring system may include the following components:
Wedges and load-bearing plates: They are used to clamp and anchor prestressed steel strands or bars at the ends of concrete members. The wedges are inserted into specially designed anchor heads and the support plates distribute the prestress evenly to the concrete.
Pipe: Used to surround prestressed steel tendons during concrete pouring. They provide passage for tendons and protect them from corrosion and damage.
Force application equipment: Hydraulic jacks and pumps are used to apply initial prestressing force to the tendons and make adjustments during construction.
Grouting: After the tendons are stressed, high-strength grout is injected into the pipes to bond the tendons to the surrounding concrete and protect them from corrosion.
Anchors: These are the components located at the ends of tendons that transfer the prestressing force to the concrete. They are essential to ensure the stability and long-term performance of prestressed concrete structures. It is important to consult with a structural engineer or qualified professional to ensure that the stress anchoring system is designed and installed according to the specific requirements of your building project.
Advantageous
Commonly used in prestressed concrete structures to anchor and secure the ends of prestressed tendons within the concrete structure, the system has a good performance of expansion self-adjusting, wedges clips follow-up and holding performance steady, high-efficiency of anchoring factor, wide range of options to facilitate the construction operation.
Applications
Widely used in highway, coal mine roadway, railway, bridge beams, housing construction, hydraulic construction, tower, large tanks of concrete, rock anchors and ground anchors and other projects.
