Wedge-shaped prestressed tendon low-retraction anchoring device s and using method
The invention provides a wedge-shaped prestressed tendon low-retraction anchoring device and a using method. The wedge-shaped prestressed tendon low-retraction anchoring device comprises a low-retraction anchor plate, a clamping piece, a wedge-shaped base plate, an anchor base plate and a spiral rib, wherein the wedge-shaped base plate is installed between the low-retraction anchor plate and the anchor base plate. The wedge-shaped prestressed tendon low-retraction anchoring device has the beneficial effect that the problem that a flat anchorage device cannot realize low retraction and tensionis particularly solved. The structure is simple and reasonable; various strength requirements can be met, not only can the high-strength requirement of bridge design be met, but also the retraction amount of the anchorage device can be effectively controlled within 1 mm by pushing the wedge-shaped base plate (compensation gap) during secondary tensioning through the matched use of the inclined surface of the wedge-shaped base plate mounted between the low-retraction anchor plate and the anchor base plate; and the operation is simple and convenient.
本发明提供了一种楔形的预应力筋用低回缩锚固装置及使用方法,该预应力筋用低回缩锚固装置包括低回缩锚板、夹片、楔形垫板、锚垫板、螺旋筋，所述低回缩锚板与锚垫板之间安装有所述楔形垫板。本发明的有益效果是:本发明尤其是解决了扁形锚具无法实现低回缩张拉的问题。且本发明结构简单、合理，可满足各种强度要求，不仅可以达到桥梁设计的高强度要求，并且通过低回缩锚板与锚垫板之间安装的楔形垫板的斜面配合使用，在二次张拉时，通过推动楔形垫板(补偿间隙)，从而使锚具回缩量有效控制在1mm以内；一次推进到位，操作简单、方便。
