The invention discloses a prestress reinforcing structure and method. The prestress reinforcing structure comprises a reinforced object, a prestress string self-balancing structure and a support, wherein the prestress string self-balancing structure and the support are arranged below the reinforced object. The reinforced object comprises a steel structure and a concrete structure; a reinforced object is connected with the prestress string self-balancing structure through the connecting plate, when prestress is applied to the prestress string self-balancing structure, due to the fact that one end of the whole prestress string self-balancing structure is hinged to the support, the other end of the whole prestress string self-balancing structure is hinged to the support in a sliding mode, and the connecting plate partially releases the self-balancing pressing rod, the self-balancing pressing rod can be fixed. The self-balancing pressing rod can generate axial compression deformation and rotation at the position of the connecting plate, so that axial force generated by the prestress inhaul cable cannot be transmitted to a reinforced object and cannot be transmitted to the support, only upward counter force is transmitted to the reinforced object through the vertical supporting rod and the connecting plate, and the aim of improving the bearing capacity of the reinforced object is achieved. And the vertical deflection of the reinforced object is reduced.
本发明公开了一种预应力加固结构及方法，所述预应力加固结构包括被加固对象、设置在被加固对象下方的预应力张弦自平衡结构以及支座；被加固对象包括钢结构、混凝土结构；被加固对象与预应力张弦自平衡结构通过连接板连接，在对预应力张弦自平衡结构施加预应力时，由于整个预应力张弦自平衡结构一端铰接于支座，另一端滑动铰接于支座，并且连接板对自平衡压杆进行了部分释放，自平衡压杆可以产生轴向的压缩变形和连接板处的转动，因此预应力拉索产生的轴力不会向被加固对象传递，也不会向支座传递，仅有向上的反力通过竖向撑杆和连接板向被加固对象传递，目的是提高被加固对象的承载能力，减小被加固对象的竖向挠度。
