The invention discloses a prestressed unbonded anchor rod reinforcing steel bar. The prestressed unbonded anchor rod reinforcing steel bar comprises a main reinforcing steel bar serving as a basic bearing structure, the main reinforcing steel bar is a finish rolling unbonded reinforcing steel bar, an anti-corrosion grease layer is arranged on the surface of the main reinforcing steel bar, and a plastic film sleeve is arranged outside the anti-corrosion grease layer. A prepared pre-stressed anchor rod is characterized in that a connecting structure at the lower end of an anti-floating tensile anchor rod of a concrete prefabricated pipe column is grouting body or concrete with an expanded head, and the grouting body or concrete with the expanded head is internally wrapped with a steel reinforcement framework or a bag; the steel reinforcement framework comprises one or more reinforcing steel bars, a steel reinforcement cage with a common structure and a variable-diameter steel reinforcement cage, when the steel reinforcement cage with the common structure and a variable-diameter steel reinforcement cage are adopted, the lower ends of anti-floating tensile anchor rod steel bars of a concrete prefabricated pipe column are connected with main reinforcements of the steel reinforcement cage or the variable-diameter steel reinforcement cage, and one or more steel bar anchor rod steel bars are used for being connected with one or more steel bars; and one or more reinforcing steel bars or reinforcement cages are still arranged in the center of the bag.
一种预应力无粘结锚杆钢筋，包括主筋钢筋作为基本承力的结构，主筋钢筋为精轧无粘结钢筋，主筋钢筋表面设有防腐油脂层，防腐油脂层外设有塑料薄膜套。制备的预应力锚杆为，混凝土预制的管柱的抗浮抗拉锚杆下端连接结构为扩大头的注浆体或混凝土；扩大头的注浆体或混凝土内裹钢筋骨架或囊袋，钢筋骨架包括单根或若干钢筋、普通结构的钢筋笼、变直径钢筋笼；普通结构的钢筋笼、变直径钢筋笼时混凝土预制的管柱的抗浮抗拉锚杆钢筋下端接钢筋笼或变直径钢筋笼的主筋，使用单根或若干钢筋锚杆钢筋连接单根或若干钢筋；囊袋中央仍设有单根或若干钢筋或钢筋笼。
