Adjustable bridge external prestressing tendon reinforcing steering block device and reinforcing method
The invention relates to an adjustable steering block device for reinforcing external prestressed tendons of a bridge and a reinforcing method of the adjustable steering block device. The adjustable steering block device comprises a hollow slab beam and a steering block device body arranged on the lower side of the hollow slab beam. The steering block device comprises a bottom plate and a screw supporting plate located below the bottom plate, at least one set of adjusting screws are arranged between the bottom plate and the screw supporting plate, each set comprises two vertically-arranged adjusting screws, a steering block is arranged between the two adjusting screws in the same set, the section of the steering block is semicircular, and the arc-shaped face of the steering block faces downwards. The adjusting screw rod is in threaded connection with an upper adjusting nut and a lower adjusting nut which are used for clamping the end of the steering block in a matched mode. According to the adjustable steering block device for reinforcing the external prestressed tendons of the bridge, the damage degree to the bridge is small, the construction efficiency is high, the steering block is detachably installed, the material consumption is small, and the height of the steering block can be adjusted by matching the adjusting screw rod with the adjusting nut; the height of the steering block can be directly adjusted according to the condition of prestress relaxation to improve the prestress degree of the prestressed tendon.
本发明涉及一种可调式桥梁体外预应力筋加固转向块装置及其加固方法，包括空心板梁和设于空心板梁下侧的转向块装置；所述转向块装置包括底板和位于底板下方的螺杆支撑板，所述底板和螺杆支撑板之间设有至少一组、每组两个竖向设置的调节螺杆，同组的两调节螺杆之间设有转向块，所述转向块截面呈半圆形并且弧形面朝下，调节螺杆上螺纹连接有用以配合夹紧转向块端部的上调节螺母和下调节螺母。本发明可调式桥梁体外预应力筋加固转向块装置对桥梁破坏程度少，施工效率高，转向块采用可拆卸安装，耗材少，利用调节螺杆配合调节螺母可以对转向块进行高度调节，针对预应力松弛的情况可以直接调节转向块高度来提高预应力筋的预应力度。
