Fiber reinforcement composite material rope bridge and preparation method thereof

Abstract

The invention discloses a rope bridge made of a fiber reinforced composite material and a preparation method thereof. The rope bridge comprises a cable support tower and an inhaul cable or a suspension cable. The rope bridge is characterized in that a main body of a deck of the rope bridge consists of a plurality of bridge members made of the fiber reinforced composite material and extended alongthe length direction of the rope bridge in parallel. The preparation method comprises: preparing the plurality of the bridge members made of the fiber reinforced composite material, which are prepared by a field pull-extrusion molding machine and have same length as the deck; and arranging the plurality of the bridge members made of the fiber reinforced composite material in parallel to form a deck main body. The roper bridge, by using the longitudinally arranged bridge members made of the fiber reinforced composite material as the deck main body, can realize design and construction of the deck of a long-span or overlong-span rope bridge spanning across a kilometer or several kilometers, has the advantages of higher safety performance, light weight of the bridge body, convenient construction of the deck main body, long service life and simple construction mode of the preparation method for the rope bridge made of the fiber reinforced composite material, and can achieve quick and safe construction of the long-span or overlong-span rope bridge consisting of the bridge members made of the fiber reinforced composite material.

Description

technical field [0001] The invention belongs to the field of bridge building structures, and in particular relates to a fiber-reinforced composite material cable bridge using fiber-reinforced composite materials as the bridge deck main body and a preparation method thereof. Background technique [0002] Fiber reinforced composite (FRP) is a new type of structural material that has been widely used in civil engineering in recent years. It has significant advantages such as high strength, light weight, and corrosion resistance, and has been well applied in structural reinforcement, enclosure and anticorrosion. As the superior performance of FRP material is gradually recognized by the engineering community, many foreign projects have begun to apply it to new bridges, even long-span bridges. [0003] Since the 1970s, FRP materials have been tried to be applied in bridge engineering. The United Kingdom, the United States and Israel were the first to apply this new type of mater...

Problems solved by technology

[0006] The purpose of the present invention is to provide a fiber-reinforced composite material cable bridge that adopts fiber-reinforced composite material bridge components as the main body of the bridge deck, and is applicable to the bridge deck design of long-span and super-long-span cable bridges. The advantages of safety performance, light weight of the bridge body, convenient construction of the main body of the bridge deck, and long service life solve the defects of low span and poor safety performance of the connection points of the existing cable bridges with fiber-reinforced composite bridge components as the main body
