Description

Technical Field

[0001] The invention relates to a main cable steering support saddle of a suspension bridge, in particular to a positioning structure and a positioning method for positioning between a horizontal grid and a vertical grid. Background Art

[0002] The saddle of a suspension bridge is an important structural member that supports the main cable and turns the main cable. Usually, a grid is set at the bottom of the saddle. The main function of the grid is to provide a flat foundation plane for the main saddle so that the vertical pressure of the main cable can be evenly transmitted to the foundation concrete through the grid. In order to ensure uniform force transmission, the grid and the saddle need to maintain good contact. Since the saddle structure has high rigidity, is not easy to deform, and has good bottom plane flatness, the upper surface of the grid corresponding to the saddle is also required to have a high flatness.
