Description

Technical Field

[0001] The utility model relates to the technical field of prestressed steel bars, in particular to a prestressed steel bar fracture detection device. Background Art

[0002] Prestressed steel rods are a material used to reinforce buildings and engineering structures. They offer high strength, corrosion resistance, oxidation resistance, and fatigue resistance. In high-rise buildings, prestressed steel rods effectively support the structure, improving its safety and stability. They also increase the bearing capacity of concrete structures, enhancing their resistance to earthquakes, wind, and cracking.
