Integral tensioning device and integral tensioning method thereof
The invention discloses an integral tensioning device. The overall tensioning device comprises a pre-tightening unit and an overall tensioning unit connected with the pre-tightening unit. The pre-tightening unit comprises a pre-tightening cylinder body, a front end cover, a rear end cover, a pre-tightening piston, a first sealing element and a second sealing element; the overall tensioning unit comprises a front clamping type tensioning jack, a first guide sleeve, a first tool clamping piece, a second guide sleeve and a second tool clamping piece. The invention further discloses an overall tensioning method. According to the integral tensioning device and the integral tensioning method thereof, each single steel strand can be pre-tightened, so that the initial stress of each single steel strand is kept uniform, and the prestress tensioning quality is ensured.
本发明公开了一种整体张拉装置。所述整体张拉装置包括预紧单元以及与所述预紧单元相连接的整体张拉单元；所述预紧单元包括预紧缸缸体、前端盖、后端盖、预紧活塞、第一密封件及第二密封件；所述整体张拉单元包括前卡式张拉千斤顶、第一导向套、第一工具夹片、第二导向套及第二工具夹片。本发明还公开了一种整体张拉方法。本发明提供一种整体张拉装置及其整体张拉方法，能对各单根钢绞线进行预紧，使各单根钢绞线的初应力保持均匀，保证了预应力张拉质量。
