Fabricated net-shaped suspender tie-bar arch bridge

Abstract

The invention provides a fabricated net-shaped suspender tie-bar arch bridge. The fabricated net-shaped suspender tie-bar arch bridge is composed of prefabricated arch ribs, prefabricated tie bars, prefabricated beams, net-shaped suspenders, prefabricated bridge deck slabs, prestressed steel cables of the prefabricated arch ribs, prestressed steel cables of the prefabricated tie bars, high-strength anchor rods and cast-in-place wet joints; the prefabricated arch ribs and the prefabricated tie bars are integrally formed, the net-shaped suspenders are arranged between the prefabricated arch ribsand the prefabricated tie bars, the prefabricated beams are supported below the prefabricated tie bars through the high-strength anchor rods, and fixedly arranged below the prefabricated tie bars atintervals, and the prefabricated bridge deck slabs are laid on every two adjacent prefabricated beams, and provided with the cast-in-place wet joints. The fabricated net-shaped suspender tie-bar archbridge is generally applicable to highway bridges, branch overpass bridges and municipal bridges, the span length can reach 50-250 m, and the fabricated net-shaped suspender tie-bar arch bridge has the advantages of being high in fabricated degree, low in dead weight, strong in spanning capability, high in construction speed, excellent in mechanical performance, low in cost, good in landscaping performance and the like, and is a novel fabricated bridge structure easy to popularize.

Description

Technical field [0001] The present invention relates to the new technical field of bridge industrialization construction, in particular to a fabricated mesh suspender arch bridge. Background technique [0002] In recent years, with the rapid increase in labor costs and the increasing environmental awareness of the Chinese people, the industrialization of bridges has become the trend of the times. The 13th Five-Year Plan of the Ministry of Transport also clearly proposes to accelerate the development of industrialization of bridges. Assembled bridges are the key direction of my country's future bridge construction development, which is conducive to saving resources and energy, reducing construction pollution, and improving labor production efficiency and quality and safety. At present, domestic prefabricated bridges have achieved certain results, but most of them are limited to small and medium spans (spans less than 50m). Therefore, it is urgent to seek a new fabricated bridge s...

Problems solved by technology

In addition, dozens of road and railway network arch bridges have been built in Norway, Germany, Japan, and the United States, but there is no application in my country

[0004] Reticulated suspender-tied arch bridge is a new type of structure, which is almost blank in domestic engineering applications, while prefabricated reticulated suspender-tied arch bridge makes full use of the superior mechanical and economic performance of reticulated suspender-tied arch bridge, integrating The concept of industrialized bridge construction, each component of the bridge adopts factory prefabricated components, and the prefabricated components are assembled through reliable connecting devices to form a brand-new prefabricated bridge, especially suitable for expressways with high industrialization requirements and large spans Bridges, branch bridges and municipal bridges have not been reported at home and abroad
