Combined prestressed anchorage device
The invention relates to the technical field of anchorage devices, in particular to a combined prestressed anchorage device which comprises an anchor backing plate, a corrugated pipe is fixedly installed on the anchor backing plate, a locking anchor is installed on the anchor backing plate, four first stranded wire holes are evenly formed in the locking anchor, first clamping pieces are arranged in the four first stranded wire holes in a sleeved mode, and a second clamping piece is arranged in the first clamping pieces. The locking anchor is provided with a pre-tightening assembly, the pre-tightening assembly comprises four pre-tightening screw rods fixedly installed on the locking anchor and a pre-tightening plate connected to the four pre-tightening screw rods in a sliding mode, and the pre-tightening plate is provided with a second wire twisting hole with the same size as the first wire twisting hole of the locking anchor; the four pre-tightening screws are located between the locking anchor and the pre-tightening plate and are in threaded connection with pre-tightening nuts, and the pre-tightening plate is provided with a pressing assembly. The pre-tightening device and the pressing assembly are arranged on the locking anchor, so that the problem that the steel strand shrinks in the steel strand clamping process of a clamping piece, and consequently the prestress of the steel strand is lost is solved.
本发明涉及锚具技术领域，具体为一种组合式预应力锚具，包括锚垫板，所述锚垫板上固定安装有波纹管，所述锚垫板上安装有锁紧锚，所述锁紧锚上均匀开设有四个一号绞线孔，四个所述一号绞线孔内均套设有一号夹片，所述锁紧锚上设有预紧组件，所述预紧组件包括固定安装在锁紧锚上的四个预紧螺杆与滑动连接在四个预紧螺杆上的预紧板，所述预紧板上开设有与锁紧锚一号绞线孔尺寸相同的二号绞线孔，四个所述预紧螺杆位于锁紧锚与预紧板之间均螺纹连接有预紧螺母，所述预紧板上设有压紧组件。本发明通过在锁紧锚上设置预紧装置与压紧组件，解决了夹片在夹紧钢绞线过程钢绞线收缩，造成钢绞线预应力损失的问题。
