Anchoring system and tensioning method for steel pull rod with dead anchors at two ends
The invention discloses a steel tie rod anchoring system with two ends anchored and a tensioning method, and relates to the technical field of suspension bridge steel tie rod anchoring systems. The steel tie rod anchoring system comprises a tie rod, and at least one end of the tie rod is fixedly provided with an integrally-formed rod head; the two anchor plates are respectively arranged on the pull rods in a sleeving manner; the two ends of the embedded steel pipe abut against the two anchor plates, and spiral steel bars are further arranged on the outer side of the embedded steel pipe. The tensioning assembly is arranged on one anchor plate and used for adjusting the distance between the anchor plate and the connecting flat plate. One side of the gasket is matched with the rod head in shape, and the other side of the gasket abuts against the anchor plate or the connecting flat plate. The connecting flat plate is connected with the main rope through the length adjusting rod. According to the anchoring system, an original threaded connection structure is replaced by the end of the pull rod through the forging forming technology, corrosion and loosening hidden dangers of threaded connection are eliminated, and the two ends of the anchoring system are anchored to form a dead anchor structure; the requirement for prestress construction of an anchoring system is met, and the use safety of a bridge structure is further improved.
本发明公开一种两端死锚的钢拉杆锚固系统及张拉方法，涉及悬索桥钢拉杆锚固体系技术领域，包括：拉杆，拉杆至少有一端部固定安装有一体成型的杆头；锚板设置有两块，且分别套设于拉杆上；预埋钢管两端与两锚板抵接，且预埋钢管外侧还设置有螺旋钢筋；张拉组件设置于一锚板上，用于调节锚板与连接平板的间距；垫圈一侧形状与杆头形状适配，另一侧抵接在锚板或连接平板上；连接平板通过调长杆与主索连接。本锚固系统通过将拉杆端部通过锻造成型技术，代替原有螺纹连接结构，消除螺纹连接的腐蚀和松动隐患，使锚固系统两端锚固形成死锚结构；满足锚固系统预应力施工的需求，并进一步提高桥梁结构的使用安全性。
