Problems solved by technology

Among them, ordinary reinforced concrete and prestressed reinforced concrete are limited in their application in long-span bridges due to their large self-weight; steel plate and asphalt concrete pavement structures have shortcomings such as low rigidity, poor thermal stability, insufficient bonding force, and high cost. It is not widely used; the bridge deck composed of ordinary steel plate and concrete, because the surface of the steel plate is smooth, and the bending rigidity of the steel plate is very small, the bonding and overall workability of the combination with the concrete are poor

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...

Abstract

The invention discloses a combined bridge deck of arched corrugated steel plates and concrete, and the combined bridge deck comprises a bridge deck substrate consisting of a plurality of rows of arched corrugated steel plates arranged in parallel, a bridge deck bottom supporting structure for supporting and fixing the bridge deck substrate, and a concrete top layer formed on the bridge deck substrate in a pouring manner; the bridge deck bottom supporting structure is formed by assembling a plurality of beams which comprise a plurality of rows of lower vertical beams arranged in parallel and aplurality of lines of lower beams arranged in parallel; each row of arched corrugated steel plates are all fastened between two rows of lower vertical beams; arch springings on the left and right of the corrugated steel plates are fixedly arranged on the two adjacent rows of lower vertical beams respectively; the corrugation of each corrugated steel plate is in the transverse direction; and the rows of lower vertical beams and the rows of corrugated steel plates form a formed bottom template for pouring the formed concrete top layer. The combined bridge deck of arched corrugated steel plates and concrete is simple in structure, convenient to manufacture and construct and good in structural mechanical property, and can be used for effectively solving the problems existing in the existing bridge deck structure.

Description

technical field [0001] The invention relates to a steel plate and concrete composite bridge deck, in particular to an arch corrugated steel plate and concrete composite bridge deck. Background technique [0002] At present, the bridge decks of truss structure bridges and steel box structure bridges generally adopt three structural forms: reinforced concrete, steel plate and asphalt concrete pavement, steel plate and concrete combination, and each structure has its own characteristics. Among them, ordinary reinforced concrete and prestressed reinforced concrete are limited in their application in long-span bridges due to their large self-weight; steel plate and asphalt concrete pavement structures have shortcomings such as low rigidity, poor thermal stability, insufficient bonding force, and high cost. Also can not obtain extensive application; The bridge deck of common steel plate and concrete combination, because the steel plate surface is smooth, and the flexural rigidity ...
