Lightweight external prestressing reinforcing system
The invention provides a lightweight external prestressing reinforcing system. The system comprises two anchoring units (1), at least one steel strand (2) and a plurality of vibration reduction cable clamps (3), the two anchoring units (1) are arranged at the two ends of the bottom face of a bridge correspondingly, the anchoring units (1) anchor the steel strand (2) and enable the two ends of the steel strand (2) to be bent downwards in a broken line mode, the bending angle is 4-10 degrees, the vibration reduction cable clamps (3) are evenly arranged on the bottom face of the bridge between anchorage device units (12), the steel strand (2) penetrates through the vibration reduction cable clamps (3), and the vibration reduction cable clamps (3) are used for performing vibration reduction on the middle section of the steel strand (2); and the steel strand (2) is an unbonded prestressed steel strand (2). According to the system, by means of an end steering and dispersing anchoring device, it is guaranteed that the high reinforcing efficiency is achieved, and meanwhile the construction and stress requirements of tensioning and anchoring are met.
本发明提供了一种轻量化体外预应力加固体系，包括两个锚固单元(1)、至少一条钢绞线(2)和若干减振索夹(3)，两个所述锚固单元(1)分别设置于桥梁底面两端位置，所述锚固单元(1)锚固所述钢绞线(2)并使所述钢绞线(2)在两端位置呈折线向下弯折，弯折角为4～10°，所述减振索夹(3)均匀设置于所述锚具(12)单元之间的所述桥梁底面，所述钢绞线(2)穿过所述减振索夹(3)，所述减振索夹(3)用于对所述钢绞线(2)中间段进行减振；所述钢绞线(2)为无粘结预应力钢绞线(2)。本发明通过端部转向和分散锚固装置，确保在取得较高的加固效率的同时，满足张拉、锚固的构造和受力要求。
