The invention provides a low-retraction anchorage device for compensating retraction by using a gasket. The low-retraction anchorage device comprises a working anchor plate, a working clamping piece and a compensation gasket. Compared with a common anchorage device, the retraction amount of a steel strand in tensioning construction can be reduced, and the prestress loss is reduced; compared with an existing low-retraction anchorage device, the low-retraction anchorage device has the advantages of being wide in application range, capable of saving material cost and convenient to machine. According to the tensioning method of the low-retraction anchorage device for compensating retraction by using the gasket, during second-time tensioning, the retraction amount of the steel strand tensionedfor the first time is eliminated through the method of lowering the compensation gasket on the working anchor plate; the processes of disassembling a jack, installing a supporting angle, installing apull rod and the like are not needed in the two-time tensioning process, the tensioning process is greatly simplified, and tensioning construction operation is facilitated.
一种用垫片补偿回缩的低回缩锚具，包括工作锚板、工作夹片和补偿垫片；对比普通锚具，可以降低张拉施工中钢绞线的回缩量，减少预应力损失；对比现有低回缩锚具，拥有适用范围广，节约材料成本、加工方便的优点。用垫片补偿回缩的低回缩锚具张拉方法，在第二次张拉时，通过在工作锚板下放补偿垫片的方法，消除第一次张拉钢绞线的回缩量；两次张拉中间不需要拆卸千斤顶、安装撑角、安装拉杆等过程，张拉过程大大简化，利于张拉施工作业。
