Anchorage device for tensioning external prestressed cable
The anchorage device comprises an anchor plate, a pressure bearing plate, a sealing cylinder and a plurality of sealing washers, the pressure bearing plate, the sealing cylinder and the anchor plate are provided with a plurality of first mounting holes, a plurality of second mounting holes, a plurality of third mounting holes and a plurality of fourth mounting holes respectively, the bearing plate is connected with the anchor plate through the first mounting holes and the third mounting holes, the sealing cylinder is connected with the anchor plate through the second mounting holes and the fourth mounting holes, a plurality of first sealing grooves are formed in one side of the anchor plate, the first sealing grooves and the third mounting holes are in one-to-one correspondence and are coaxially arranged, and second sealing grooves are formed in the other side of the anchor plate in the circumferential direction of the anchor plate. A third sealing groove is formed in one side of the sealing cylinder in the circumferential direction of the sealing cylinder, the second sealing groove and the third sealing groove are oppositely arranged, and the sealing washers are laid in the first sealing grooves and the second sealing grooves correspondingly. The sealing grooves are formed in the connecting positions of the anchorage device components, so that water vapor and other impurities are prevented from entering the anchorage device from the connecting positions.
本发明涉及一种用于体外预应力索张拉用锚具，包括锚板、承压板、密封筒和多个密封垫圈，承压板、密封筒和锚板上分别开设有多个第一安装孔和多个第二安装孔和多个第三安装孔和第四安装孔，承压板与锚板通过第一安装孔和第三安装孔连接，密封筒与锚板通过第二安装孔和第四安装孔连接，锚板的一侧开设有多个第一密封槽，第一密封槽与第三安装孔一一对应且同轴设置，锚板另一侧绕其周向开设有第二密封槽，密封筒一侧绕其周向开设有第三密封槽，第二密封槽与第三密封槽相对设置，各个密封垫圈分别铺设于各个第一密封槽和第二密封槽。本发明通过在锚具部件的连接处开设密封槽，避免了水汽等杂质从连接处进入锚具内部。
