The invention discloses a prefabricated combined assembled anti-floating tensile prestressed anchor rod piece which comprises an unbonded steel bar or a main reinforcement steel bar, a prestressed anchor rod adopts a hollow pipe column and nuts for locking. The unbonded reinforcing steel bar or the main reinforcing steel bar penetrates into the pipe column, the prefabricated hollow pipe column istaken as a support, the two ends of the steel bar are tensioned, prestress is applied, and then the two ends of the pipe column are locked by the nuts, so that the prefabricated prestressed anchor rodpiece is formed. The main reinforcement steel bar is made of high-strength finish-rolled thread steel. An anticorrosive grease layer is arranged on the surface of the main reinforcement steel bar, and a sleeve is arranged outside the anticorrosive grease layer, so that the prefabricated prestressed unbonded steel bar is formed.
一种预制组合装配式抗浮抗拉预应力锚杆件,包括无粘结钢筋或主筋钢筋,预应力锚杆用空心管柱,锁锚的螺母;将无粘结钢筋或主筋钢筋穿入管柱内,以预制空心管柱为支架,张拉上述钢筋两端,施加预应力后,用螺母锁定在管柱两端,形成预制预应力锚杆件。主筋钢筋为高强精轧螺纹钢;在主筋钢筋表面设有防腐油脂层,防腐油脂层外设有套管,形成预制预应力无粘结钢筋。
