Abstract

The invention relates to a main cable strand anchoring device of a suspension bridge, which comprises a strand boot, a pull rod and a pull rod anchoring assembly; the strand boot is a semi-cylindricalblock structure, which comprises a circular arc surface, semicircular surfaces on both sides and a rectangular surface on the opposite side of the circular arc surface; a plurality of strand boot grooves for locating and winding steel wires are formed in the circular arc surface of the strand boot, and the track of the strand boot grooves is parallel to the outer arc of the strand boot; the strand boot is provided with a pull rod opening perpendicular to the rectangular surface; the pull rod passes through the pull rod opening, wherein one end of the pull rod is anchored to the front anchor surface by the pull rod anchoring assembly, and the other end is fixed to the rectangular surface of the strand boot by the pull rod anchoring assembly. According to the main cable strand anchoring device of the suspension bridge, the anchoring problem of the main cable strand of an AS-method suspension bridge can be solved, and has the advantages of clear route of transmission force, simple and reliable force, in line with the construction process of the main cable strand of the AS-method suspension bridge, and the construction technology is simple and convenient.

Description

technical field [0001] The invention belongs to the technical field of suspension bridge structures, and in particular relates to an anchoring device for main cable strands of a suspension bridge. Background technique [0002] At present, there are two main methods for erecting the main cables of suspension bridges: the aerial spinning method (AS method) and the prefabricated parallel wire strand method (PPWS method). The AS method refers to the method of using the steel wire as the traction unit, weaving multiple steel wires into a steel wire strand on the catwalk, and then binding the strands to form the main cable; the PPWS method uses the strand as the traction unit, and then the cable A method of bundling strands to become the main cable. At present, the PPWS method is used in my country to erect the main cable strands of suspension bridges, while the aerial spinning method (AS method) has no construction precedent in mainland China. [0003] Due to the heavy main cab...
