The invention provides a self-anchored suspension bridge catwalk load-bearing cable steering structure. The self-anchored suspension bridge catwalk load-bearing cable steering structure comprises a steering beam fixed onto the top surface of an anchoring section beam, wherein one end of the steering beam overhanging out of the anchoring section beam is provided with a plurality of steering saddlesat interval, and each steering saddle is provided with a catwalk load-bearing cable; each catwalk load-bearing cable passes through the corresponding steering saddle and is fixed onto the anchoring section beam through a beam surface anchoring device; and a limit device of each catwalk load-bearing cable is arranged on the corresponding steering saddle. By utilizing the catwalk load-bearing cablesteering structure provided by the invention, the catwalk outside load-bearing cable far away from a bridge center line can be vertically and horizontally turned and then anchored to the anchoring device on an anchoring section beam surface, thereby avoiding that the outside load-bearing cable is anchored to the side of an anchoring section, also avoiding the arrangement of high-bearing-capacitycorbels on the side of the beam, reducing the construction difficulty and greatly simplifying anchoring device structures of the catwalk load-bearing cables, and improving the anchoring safety of thecatwalk load-bearing cables.
