Large-span net rack anchor head inhaul cable and arc net rack tensioning method
The invention relates to a large-span net rack anchor head inhaul cable and an arc net rack tensioning method. The large-span net rack anchor head inhaul cable comprises a first fixing support; a first anchor head is arranged at the front end of the first fixing support; a second anchor head is arranged at the front end of the first anchor head, and an anchor head connecting piece is arranged at the front end of the second anchor head; a center hole jack is arranged at the front end of the anchor head connecting piece; a third anchor head is arranged at the front end of the center hole jack; taper holes are formed in the first anchor head, the second anchor head and the third anchor head respectively; lock cylinders are arranged in the taper holes and are cone frustums defined by a plurality of petal bodies; a connecting hole is formed in the center of each lock cylinder; and steel strands are connected in penetrating holes in a penetrating manner. The large-span net rack anchor head inhaul cable is simple in structure and convenient to mount and dismount, can be repeatedly tensioned for multiple times to meet the construction requirement, can effectively prevent the steel strands from slipping off, and reduces the safety risk.
本发明涉及一种大跨度网架锚头拉索及弧形网架张紧方法，大跨度网架锚头拉索包括第一固定支座，在第一固定支座的前端设置有第一锚头，在第一锚头的前端设置有第二锚头，在第二锚头的前端设置有锚头连接件，在锚头连接件的前端设置有穿心千斤顶，在穿心千斤顶的前端设置有第三锚头，在第一锚头、第二锚头以及第三锚头上分别设有锥形孔，在锥形孔内设置有锁芯，锁芯为多个瓣体合围成的圆锥台，在锁芯中心设有连接孔，钢绞线穿接在穿接孔内。本发明结构简单，便于安装和拆卸，能够重复多次张拉以达到施工要求，能够有效防止钢绞线的滑脱，降低安全风险。
