Expressway hogging moment bridge flat anchor integral tensioning structure and tensioning method
The invention relates to the technical field of traffic beam bridge engineering, in particular to an overall tensioning structure and method for a hogging moment bridge flat anchor of an expressway. The overall tensioning structure of the expressway hogging moment bridge flat anchor comprises two numerical control hosts, two anchor bearing plates and two tensioning jacks which are symmetrically arranged. According to the method, intelligent tensioning fine construction is carried out on bridge prestress, real-time whole-course tracking and timely error correction are carried out on prestress tensioning, the situation that in traditional tensioning, the measurement precision is low is basically eliminated, the size of under-anchor prestress is practically and effectively controlled, the construction technology is improved, the tensioning process is standardized, and the prestress construction quality is improved; compared with the prior art, safety and durability of a bridge structure are guaranteed, the whole-life-cycle cost of the bridge is reduced, meanwhile, rapid, convenient and rapid fixing and clamping of the embedded steel beam are achieved, and stability and reliability of tensioning of the embedded steel beam in the construction process are guaranteed.
本发明涉及交通梁桥工程技术领域，尤其提供一种高速公路负弯矩桥梁扁锚整体张拉结构及张拉方法。该高速公路负弯矩桥梁扁锚整体张拉结构包括两个数控主机、两个锚垫板及两个对称设置的张拉千斤顶。本发明实行桥梁预应力进行智能张拉精细化施工，对预应力张拉实时全程跟踪与及时纠错，基本上消除传统张拉中测量精度较低，切实有效的控制锚下预应力的大小，改进施工工艺和规范张拉过程，提高预应力施工质量，保证了桥梁结构安全和耐久性，降低了桥梁全寿命周期成本，同时，实现了对预埋钢束的迅速、方便、快捷的固定夹持，确保了施工过程中对预埋钢束张拉的稳定性和可靠性。
