Reinforced concrete beam external prestressing reinforcing structure and method of NPR steel bars
The invention provides a reinforced concrete beam external prestress reinforcing structure of NPR steel bars. The reinforced concrete beam external prestress reinforcing structure comprises the NPR steel bars, an anchoring structure and a prestress applying assembly used for tensioning the NPR steel bars. The prestress applying assembly comprises a reinforcing steel bar prestress applying anchorage device, a cross-core type tensioning jack, a guide rod, a temporary fixing assembly and an anchor plate assembly; the temporary fixing assembly comprises clamping plate clamps capable of being clamped and fixed to the two sides of the reinforced concrete beam structure, and mounting bases arranged below the clamping plate clamps. The problem of large deformation under dynamic load can be solved, the structure is simple, and installation is convenient; according to the method, the external prestressing reinforcing structure of the reinforced concrete beam is used, holes are not punched in the concrete beam structure when the tensioning jack is temporarily fixed, and secondary damage to the reinforced concrete beam structure during external prestressing reinforcing can be reduced.
本发明提供一种NPR钢筋的钢筋混凝土梁体外预应力加固结构，包括NPR钢筋、锚固结构以及用于张拉所述NPR钢筋的预应力施加组件；所述预应力施加组件包括钢筋预应力施加锚具、穿心式张拉千斤顶、导杆、临固组件和锚板组件；所述临固组件包括可夹紧固定在所述钢筋混凝土梁结构两侧的夹板夹具和设置在所述夹板夹具下方的安装座，本发明的加固结构通过对预应力材料进行优化以保证预应力钢筋混凝土梁在实现加固的同时，可以克服动力荷载下的大变形问题，且结构简单，安装方便；本发明的方法使用前述的钢筋混凝土梁体外预应力加固结构，在临时固定张拉千斤顶时不在混凝土梁结构上打孔，能够减少体外预应力加固时对钢筋混凝土梁结构的二次损伤。
