Abstract

The invention relates to the technical field of steel structure bridge engineering installation and construction, in particular to a steel structure bridge installation segmental linear adjustment andbridge overall descending device. The descending device includes a short steel pipe, a jacking protection plate, a first inclined face sliding block, a second inclined face sliding block, two stop blocks, at least four stop block stiffening plates, at least four adjusting bolts and at least two sliding plates. According to the steel structure bridge installation segmental linear adjustment and bridge overall descending device, the contact face between the two inclined face sliding blocks and the contact face between the inclined face sliding blocks and the upper flange of a distributive beamare made of sliding plate materials, and the advantages of low friction coefficient, good self-lubrication, high adaptability, wear resistance, recycling and the like are achieved; and the descendingdevice can control the overall height of each jacking or descending of a bridge, safety of whole falling is ensured, the problems that previous industrial implementation tools of steel structure bridge installation segmental linear adjustment and overall installation location has high safety construction hidden dangers, and major safety accidents are prone to being caused are solved.

Description

technical field [0001] The invention relates to the technical field of installation and construction of steel structure bridge engineering, in particular to a segmental line type adjustment of steel structure bridge installation and a device for overall lowering of the bridge. Background technique [0002] With the vigorous development of my country's infrastructure construction, prefabricated steel structure bridges have been widely used in road engineering construction. Due to the limitations of road transportation and on-site lifting machinery hoisting conditions, steel structure bridges are usually made of a steel structure in the factory The bridge project is divided into several sections as a whole, and the bridge in each section is decomposed into two horizontal beams and several longitudinal beam segments, and the bridge segments in each section are manufactured in the factory. [0003] In the past, segmental alignment adjustment and overall installation of constructi...
