The invention relates to a manufacturing and assembling process for steel truss girder segments of a double-layer highway bridge deck. The manufacturing and assembling process is characterized by comprising the following specific manufacturing and assembling processes: S1, manufacturing truss pieces; s2, manufacturing upper-layer bridge floor plates; s4, manufacturing lower-layer bridge floor plates; s5, integrally splicing the steel truss girder sections of the double-layer highway bridge floor; modularized splicing is adopted for the bridge, modules of part of the bridge can be spliced in a bridge production site, the difficulty of site bridge fabrication is lowered, the labor amount of bridge manufacturing is reduced, the time of bridge manufacturing is shortened, and the working efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of manufacturing double-layer highway bridge decks, in particular to a manufacturing and assembling process for steel truss girder segments of double-layer highway bridge decks. Background technique [0002] With the rapid development of society and economy, the pressure of land transportation is becoming more and more prominent. In order to solve this pressure, it is imperative to build a large number of railways, highways and other projects. The use of bridges tends to be inevitable, and people are also designing the structures of bridges with different distances. [0003] At present, some steel trusses are in the form of upper and lower layers, the sides of the upper and lower decks are connected by trusses, and the upper deck and the lower deck are laid with bridge deck units on T-shaped beams. Since each part is manufactured separately in the manufacturing process, when assembling on site, due to the b...
