[0002] A cable-stayed bridge is also called a cable-stayed bridge. It is a bridge in which the main beam is directly pulled on the bridge tower by many cables. It is a structural system composed of pressure-bearing towers, tensioned cables and bending beams. It can be regarded as a multi-span elastically supported continuous beam with cables replacing piers.

[0003] The nuts for bridge cables in the prior art are usually ordinary nuts with a screw hole in the middle, which have a relatively simple structure. When the nuts are subjected to strong external forces, they are easily damaged, affecting the normal use of the nuts. In addition, when traditional nuts are screwed onto bolts, the bolts will extend out of the nuts, and such nuts lack a better sealing structure, which cannot provide sealing protection for the bolts extending out of the nuts, causing the bolts to be easily eroded by rainwater, thereby reducing their service life.

[0004] Based on the above situation, the utility model proposes a heavy-duty nut for bridge cables, which can effectively solve the above problems. Utility Model Content
