Zusammenfassung:	The invention provides a high-temperature-resistant and corrosion-resistant prestressed steel strand, and relates to the technical field of steel strands. The high-temperature-resistant and corrosion-resistant prestressed steel strand comprises a middle wire body, a plurality of outer steel wires are arranged on the outer surface of the middle wire body, a fixing frame is fixed to one end of the middle wire body, a plurality of through grooves are formed in the middle of the fixing frame, stabilizing frames are fixed to the two ends of the fixing frame, and sliding grooves are formed in the middles of the two stabilizing frames. Sliding discs are slidably connected to the inner walls of the two sliding grooves correspondingly, and first springs are fixed to the ends, away from each other, of the two sliding discs correspondingly. According to the high-temperature-resistant and corrosion-resistant prestressed steel strand, the outer steel wire extrudes the abutting frame to conduct moving operation, the stable
