Prestressed steel strand tightening and releasing device
The invention provides a prestressed steel strand tightening and releasing device, and belongs to the technical field of building construction, the prestressed steel strand tightening and releasing device comprises a tensioning piston pipe and a clamping piece sleeve, the clamping piece sleeve is sleeved with a sealing cover nut, the sealing cover nut is sleeved with an anchor removing sleeve, and the tensioning piston pipe is sleeved with the anchor removing sleeve; three tool clamping pieces are annularly connected to the clamping piece sleeve at equal intervals, the rear ends of the tool clamping pieces extend out of the clamping piece sleeve, and each tool clamping piece is provided with an outer conical surface with the radius gradually reduced from front to back; a reducing section is arranged at the front end of the tensioning piston pipe, and the outer diameter of the reducing section is smaller than that of the tensioning piston pipe; an anchor cup is connected to the reducing section, and the anchor cup is provided with an inner conical surface matched with the outer conical surface of the tool clamping piece; the tensioning piston pipe is sleeved with a spring, and the tool clamping piece, the anchor cup and the spring are all located in the anchor removing sleeve; the two ends of the spring are connected to the anchor cup and the anchor removing sleeve respectively. When the spring is completely compressed, the matched conical surfaces of the tool clamping piece and the anchor cup can be completely separated; the device is simple in structure, the tool clamping piece is convenient to dismantle, and the situation that the steel strand is stuck can be avoided.
本申请提供一种预应力钢绞线紧放装置，属于建筑施工技术领域，包括张拉活塞管和夹片套管，所述夹片套管上套装有封盖螺母，所述封盖螺母上套装有褪锚套筒，所述褪锚套筒套装在张拉活塞管上；所述夹片套管上环形等距连接有三个工具夹片，所述工具夹片后端伸出夹片套管，工具夹片设有由前往后半径逐渐缩小的外锥面；所述张拉活塞管前端设有缩径段，所述缩径段外径小于张拉活塞管的外径；所述缩径段上连接有锚杯，锚杯设有与工具夹片的外锥面相匹配的内锥面；所述张拉活塞管外套装有弹簧，所述工具夹片、锚杯和弹簧均位于褪锚套筒内；所述弹簧的两端分别连接在锚杯和褪锚套筒上；当弹簧完全压缩时，工具夹片和锚杯相匹配的锥面能完全脱离；本装置结构简单，方便拆除工具夹片，能避免出现钢绞线卡死的情况。
