The invention discloses a bridge prestress anchorage device, relates to the technical field of a bridge prestress, and aims at solving problems that after buffering is performed for a period of time,all components of the prestress anchorage device are difficult to recover, the buffering performance is reduced, a prestress effect is decreased, and use requirements cannot be met. A base is arrangedabove a concrete block, a metal sleeve is arranged above the base, the metal sleeve and the base are arranged to be an integrated structure, a conical anchor seat is arranged in the metal sleeve, oneend of the conical anchor seat penetrates through the base and extends into the concrete block, and a conical anchor ring is arranged above the conical anchor seat. The conical anchor ring is connected with the conical anchor seat in a joggled mode, a buffer piece is arranged between the conical anchor ring and the conical anchor seat, the two ends of the buffer piece extend into the conical anchor ring and the conical anchor seat respectively, clamping pieces are arranged in the conical anchor ring and the conical anchor seat respectively, and the inner walls of the clamping pieces are attached to a steel strand.
本发明公开了一种桥梁预应力锚具，涉及桥梁预应力技术领域，为解决缓冲一段时间后预应力锚具各部件之间难以复原，缓冲性能下降，预应力效果降低，不能满足使用需求的问题。所述混凝土块的上方设置有基座，所述基座的上方设置有金属套筒，且金属套筒与基座设置为一体结构，所述金属套筒的内部设置有锥形锚座，且锥形锚座的一端贯穿基座并延伸至混凝土块的内部，所述锥形锚座的上方设置有锥形锚环，且锥形锚环与锥形锚座榫接，所述锥形锚环与锥形锚座之间设置有缓冲件，且缓冲件的两端分别延伸至锥形锚环和锥形锚座的内部，所述锥形锚环和锥形锚座的内部均设置有夹片，所述夹片的内壁与钢绞线相贴合。
