预应力混凝土用螺纹钢筋
Application Summary AI generated
This standard specifies the dimensions, mechanical properties, and testing methods for high-strength threaded steel bars used to apply compressive prestress to concrete structures. It is primarily applied in the construction of large-span bridges, high-rise buildings, and heavy-load industrial foundations where post-tensioning or pretensioning systems are employed to enhance structural integrity and crack resistance.
