Bridge external prestressing anchoring device
The invention discloses a bridge external prestressing anchoring device, which relates to the technical field of anchoring devices, and comprises an anchor box, a protective pipe, a prestressing cable, an anchoring plate, a support plate and an anchorage device, and further comprises an in-box filling assembly and a through hole plugging assembly, an annular sealing ring is arranged at the contact position of the bottom of the anchor box and the bridge; the in-box filling assembly comprises an in-box expanding bag; the in-box expansion bag is a rubber elastic bag in which paraffin is arranged, an injection channel pipe is fixed on the in-box expansion bag, and the in-box expansion bag is arranged in the anchor box when the anchor box is installed; the through hole plugging assembly is used for sealing the through hole and comprises an annular soft bag, the annular soft bag is an annular rubber soft bag, and an injection pipe is fixed to the annular soft bag; the annular soft bag is arranged on the prestressed cable in a sleeving mode, and after filling of the expansion bag in the box is completed, an operator pumps paraffin into the annular soft bag through the injection pipe by means of the paraffin pumping assembly so that the annular soft bag can expand. The technical effects that the sealing effect of the bridge external pre-stress anchoring device is relatively good, and corrosion damage to the pre-stress cable is not prone to being caused are achieved.
本申请公开了一种桥梁体外预应力锚固装置，涉及锚固装置技术领域，包括锚箱、防护管、预应力索、锚固板、支撑板和锚具，还包括箱内填充组件和通孔封堵组件；锚箱的底部与桥梁的接触位置设有环状的密封圈；箱内填充组件包括箱内涨大囊；箱内涨大囊为内置石蜡的橡胶弹性囊，其上固定有注入通道管，在锚箱安装时设置在锚箱内部；通孔封堵组件用于封闭通孔，包括环状软囊，环状软囊为环状的橡胶软囊，其上固定有注入管；环状软囊套设在预应力索上，在箱内涨大囊填充完成后，操作人员利用泵蜡组件通过注入管向环状软囊泵送石蜡进而使得环状软囊涨大；实现了桥梁体外预应力锚固装置的密闭效果相对较好且不易造成预应力索锈蚀损伤的技术效果。
