A flat-stayed cable bridge with tubular deck

Abstract

The invention discloses a pipe type bridge floor flat pull cable bridge which comprises a group of steel cables (1) connected with two shores. A left end steel pipe bridge floor assembly (2), a group of intermediate steel pipe bridge floor assemblies (3) and a right end steel pipe bridge floor assembly (4) are sequentially arranged on the steel cables from left to right. The bottom of each steel pipe bridge floor assembly is provided with a group of screws (5), and the screws (5) are connected with the steel cables through connecting plates (6) and nuts (7). According to the pipe type bridge floor flat pull cable bridge, the problems that an existing wood structure bridge floor plate is poor in durability and needs to be replaced frequently are solved, and the maintenance workload and cost are reduced. The problems of steel cable abrasion caused by the bridge floor plate and steel wire bending and damage are solved effectively through arc-shaped gaskets, and the service life of the bridge is prolonged. The integrity of the bridge floor plate and the steel cables is enhanced through connecting components, and running stability and safety are improved. The bridge floor plate can adapt to bridge floor deformation requirements well through clamping pins. The pipe type bridge floor flat pull cable bridge is simple in structure and convenient to install, and the bridge floor plate can be reused.

Description

technical field [0001] The invention relates to a flat-stayed cable bridge with a tubular deck, belonging to the technical field of bridge structures. Background technique [0002] Flat-stayed cable bridge is a flexible bridge system with steel cables as the force-bearing structure, the bridge deck is directly laid on the steel cables, and the line shape of the bridge deck is basically consistent with the line shape of the steel cables. Therefore, in order to adapt to the deformation of the cables, the deck of the cable-stayed bridge is usually spliced ​​longitudinally by smaller decks. The bridge deck of the existing flat-stayed cable bridge generally adopts a wooden structure, for example, the "deck structure of a flat-stayed cable bridge" disclosed by the applicant in the patent document with publication number 202989775U. Due to the low strength of the wooden structure, a thicker bridge deck is required to bear the larger vehicle load, so the requirements for the materi...

AI Technical Summary

Problems solved by technology

At the same time, the durability of the wooden structure is poor, and the bridge deck needs to be replaced frequently during the use of the bridge. The later maintenance workload is heavy and often causes traffic interruptions.

On the other hand, the anti-corrosion treatment of wooden bridge decks also has adverse effects on the environment

Therefore, the existing wooden bridge deck technology is not perfect, and limits the popularization and application of flat-stayed cable bridges
