Shaping method and clamp for main cable strand of suspension bridge

Abstract

The invention provides a shaping method and clamp for a main cable strand of a suspension bridge, and belongs to the field of engineering equipment. The method is characterized in that steel wires are marked according to the size of the steel wires; the main cable strand comprises a plurality of steel wires, and different steel wires are correspondingly marked; the steel wires are divided into a plurality of areas to be shaped through the marks on the steel wires; the plurality of steel wires are conveyed from the head end to the tail end of an operation platform; when in conveying, the plurality of steel wires in the area to be shaped between the adjacent marks are shaped into regular polygonal structures having different sections. The clamp comprises the operation platform, a regular quadrangular clamp and a regular hexagonal clamp, wherein the regular quadrangular clamp and the regular hexagonal clamp are correspondingly mounted on the operation platform. According to the method and the clamp, the cable strand is shaped in advance in the in-plant processing production stage, so that the mounting position accuracy can be ensured, and the precision meets the construction demand; in addition, the shaping processes at a construction site can be decreased, and the quality of the cable strand is prevented from reduction caused by the site shaping.

Description

technical field [0001] The invention relates to the field of engineering equipment, in particular to a method for shaping strands of main cables of a suspension bridge and a jig for strand shaping. Background technique [0002] The extra-long-span bridges spanning wide deep waters can reduce the number of deep water foundations or bridge piers in water, prevent waterborne ships from colliding, and maintain navigation capabilities. Realizing single-span breakthrough and long-span continuous spanning is one of the important issues that bridge development pays attention to and pays attention to. The cable bridge is the preferred structure of the long-span bridge, and the main cable strand of the cable bridge is the main load-bearing component of the cable bridge. In the prior art, when the main cable is anchored, the section of the main cable strand needs to be adjusted accordingly according to the site conditions, and the ppws method is often used to erect the main cable. ...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a method for shaping the main cable strands of a suspension bridge, so as to improve the problems in the prior art that the galvanized layer of the strands is easily damaged when the main cable strands are erected, resulting in reduced anti-corrosion performance and reduced use safety of the strands.

[0006] The object of the present invention is also to provide a kind of cable strand shaping fixture, to improve the prior art that the main cable shaping is done on the spot without providing a complete set of shaping equipment, so that the galvanized layer of the cable strands is easily damaged during the shaping process. question
