摘要
The standard anchoring device for PS concrete beam is composed of a male cone(10) forming axial groove on the periphery and a female cone(20) which includes an auxiliary wedge cone(30) to be inserted into the central hole(5) of the male cone(10). The auxiliary wedge corn divided into three parts is to be supported by O rubber ring(31) and has spiral grooves on the inner surface of the central hole(41') for holding a strand cable(41) to increase friction between wedge cone and strand.
