Description

Technical Field

[0001] The utility model relates to the technical field of cable-stayed bridges, in particular to a cable structure for a long-span cable-stayed bridge. Background Technique

[0002] A cable-stayed bridge, also known as a cable-stayed bridge, is a bridge structure system in which the main beam is directly pulled on the bridge tower by many stay cables. This structure system is composed of a compression-bearing tower, tensioned cables, and a bending-bearing beam body, and can be regarded as a multi-span elastic support continuous beam with stay cables replacing piers. The main components of a cable-stayed bridge include a cable tower, a main beam, and stay cables.

[0003] A cable structure for a long-span cable-stayed bridge disclosed in the publication number CN221297589U includes a cable main body. One end of the cable main body is fixedly connected with an anchoring connection column. The middle of one end of the anchoring connection column is fixedly connected with a first threaded column. A second threaded column is arranged at one end of the first threaded column. One end of the second threaded column is fixedly connected with a ball cage universal joint. One end of the ball cage universal joint is rotatably connected with a fixed ear. A connecting ear is slidably connected to the outer surface of the fixed ear. A fixing column is arranged on the outer surface of the fixed ear. In the utility model, through the setting of the ball cage universal joint, the direction of the fixed ear can be conveniently adjusted. After selecting a suitable position, the connecting ear is threadedly connected to the second connecting column, and through the setting of the fixing column, it can be locked, thereby realizing the convenient fixing of the cable and improving the locking effect, effectively preventing subsequent loosening. Although, in the utility model, through the combined use of the connecting ear and the fixed ear, the cable can be conveniently fixed on the anchor point, and through the setting of the ball cage universal joint, the direction of the fixed ear can be conveniently adjusted. After selecting a suitable position, the connecting ear is threadedly connected to the second connecting column, and through the setting of the fixing column, it can be locked, thereby realizing the convenient fixing of the cable and improving the locking effect, effectively preventing subsequent loosening.

[0004] However, this cable structure for a long-span cable-stayed bridge has the following disadvantages:

[0005] This cable structure for a long-span cable-stayed bridge has a relatively weak function of convenient installation. During use, since the device is fixed as a whole, it is not convenient for the staff to carry out installation operations, which may cause problems that are not convenient for the staff to operate.

[0006] This cable structure for a long-span cable-stayed bridge has a relatively weak anti-corrosion function. During use, since there is no waterproof structure between the cable and the fixed anchor of the device, rainwater may enter the gap between the fixed anchor and the cable, resulting in rusting between the fixed anchor and the cable and reducing the connection strength, which may cause potential safety hazards.
