Description
Technical Field
The utility model relates to a bridge suspension cable structure, in particular to epoxy steel strand wires suspension cable protective structure.
Background
A cable-stayed bridge is also called a diagonal tension bridge, is a bridge with a main beam directly pulled on a bridge tower by a plurality of guys, and is a structural system formed by combining a pressure-bearing tower, a pulled guy and a bending-bearing beam body. It can be seen as a multi-span elastically supported continuous beam with guy cables instead of buttresses. It can reduce the bending moment in the beam body, reduce the building height, lighten the structural weight and save materials. The cable-stayed bridge mainly comprises a cable tower, a main beam and a stay cable.
The stay cable is also called as stay cable, and is the main bearing member for directly transmitting the weight of the main beam and the bridge deck of the cable-stayed bridge to the tower. The material of the stay cable of the cable-stayed bridge is usually a steel cable, the form of which differs according to the method of its composition, and can be composed of parallel steel wires, parallel steel cables, single steel cable, closed steel cable or solid steel bar. Since the guy cable is placed obliquely, it is called oblique cable. The stay cable is used as the main component of the cable-stayed bridge, the strength and the toughness of the stay cable have high requirements, and the corrosion resistance of the stay cable needs to be stronger because the stay cable is placed outdoors for a long time.
Although the stay cable in the prior art adopts a certain anti-corrosion structure, the effect cannot be optimal.
