Abstract

The invention discloses an inhaul cable for a bridge. The inhaul cable for the bridge comprises two shaft sleeves, two spindle cores and an inhaul cable body, wherein the axes of the two shaft sleeves are parallel; the cross section, in the plane perpendicular to the axes of the shaft sleeves, of each spindle core is in a drop shape, each spindle core is provided with a shaft sleeve installation hole, and the two shaft sleeves are arranged in the two shaft sleeve installation holes in a cooperation mode; spindle core installation holes matched with the spindle cores in shape are formed in the two ends of the inhaul cable body, and the two spindle cores are arranged in the two spindle core installation holes in a cooperation mode. The inhaul cable for the bridge has the advantages that stress is uniform and reasonable and the bearing capacity is high.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a drag cable used for bridges. Background technique [0002] In recent years, with the continuous increase of the span of cable-stayed bridges, the self-weight of steel cables has also increased, and the bearing efficiency has decreased, which is an important factor limiting the span of bridges. [0003] In the bridges in the related art, the internal force of the cables is unreasonable, and the bearing efficiency is relatively low, which cannot meet the increasing demand for the carrying capacity of the cables. Contents of the invention [0004] The present invention aims to solve one of the above-mentioned technical problems in the prior art at least to a certain extent. For this reason, the present invention proposes a stay cable for bridges, which has the advantages of uniform and reasonable stress, strong bearing capacity, and the like. [0005] In order to ach...
