Embodiment 1
[0029] Such as figure 1 , figure 2 As shown, the present invention includes a bridge deck bottom plate composed of arched corrugated steel plates 1 arranged in parallel, a bridge deck bottom support structure for supporting and fixing the bridge deck bottom plate, and poured concrete formed on the bridge deck bottom plate top floor 2. The support structure at the bottom of the bridge deck is fixed on the load-bearing structure of the constructed bridge and is composed of multiple rib beams assembled to form a bottom plate installation foundation for the bottom plate of the bridge deck and it includes multiple The lower longitudinal beams 4 arranged in parallel in rows and the lower cross beams 5 arranged in parallel in multiple rows, the lower longitudinal beams 4 in multiple rows are arranged longitudinally and the lower cross beams 5 in multiple rows are arranged horizontally, and the lower cross beams 5 in multiple rows are arranged horizontally. The longitudinal beams 4...
Embodiment 2
[0039] In this embodiment, the difference from Embodiment 1 is that the rectangular concrete layers in the plurality of single-piece composite bridge decks are poured as a whole. In the actual construction process, the bottom support structure of the bridge deck and the bottom plate of the bridge deck are installed on site on the completed bridge load-bearing structure, and concrete is poured on the installed bottom support structure of the bridge deck and the bottom plate of the bridge deck on site to form the top layer of concrete 2 . In this embodiment, the structure, connection relationship and construction process of the remaining parts are the same as those in Embodiment 1.
[0040] To sum up, in the actual construction process, the bottom support structure of the bridge deck and the bottom plate of the bridge deck can be installed on site on the completed bridge load-bearing structure, and concrete can be poured on site to form the concrete top layer 2; a single-piece c...
