Anchorage device capable of recycling prestressed steel strands and construction method
The anchorage device comprises a connecting sleeve, a wedge-surface piston, a double-end conical clamp, a wedge-surface ring sleeve and a torsion transmission ring sleeve are sequentially arranged in the connecting sleeve from bottom to top, a sealing protection ring sleeve is arranged at the upper end of the connecting sleeve, a bottom steel bar is arranged at the lower end of the connecting sleeve, and a mounting through hole is formed in the sealing protection ring sleeve; a slurry through hole is formed in the outer wall of the connecting sleeve and located below the wedge face piston. A spiral through hole matched with a steel strand is formed in the torsion transmission ring sleeve, and a conical sinking groove is formed in the wedge surface piston; an anchor cable through hole is formed in the double-end conical clamp, conical anchor cable clamps are arranged at the upper end and the lower end of the double-end conical clamp correspondingly, and the two conical anchor cable clamps can be contained in the conical sinking groove and the conical through hole correspondingly so that the penetrating steel strand can be clamped. The device is reasonable in design and easy to mount, unanchor and dismount, and steel strands can be conveniently recycled.
本申请涉及一种可回收预应力钢绞线的锚具及施工方法，包括连接套筒，连接套筒内从下到上依次设有楔面活塞、双头锥形夹具、楔面环套和扭力传动环套，连接套筒上端设有密封保护环套，下端设有底部钢筋，密封保护环套上设有安装通孔，连接套筒外壁上设有浆液通孔，浆液通孔位于楔面活塞下方；扭力传动环套上设有与钢绞线配合的螺旋状通孔，楔面活塞上设有锥形沉槽；双头锥形夹具上设有锚索通孔，双头锥形夹具上下两端分别具有锥形锚索夹，两个锥形锚索夹能够分别收纳于锥形沉槽和锥形通孔内，以实现夹紧穿过的钢绞线。本申请设计合理，安装及解锚拆卸简单，且便于对钢绞线回收。
