Problems solved by technology

[0003] The inventor found that traditional bridge decks are prone to problems such as pavement damage, fatigue cracking, and insufficient local rigidity, and it is difficult to repair the steel structure after cracking, which greatly increases the cost of operation and maintenance, and the construction is more complicated. Factors such as tension and untimely maintenance often lead to cracking of the bridge deck, which in turn causes corrosion of the steel bars in the bridge deck and reduces the performance of the bridge deck

Abstract

The invention relates to a corrugated steel-rubber concrete combination bridge deck slab. The corrugated steel-rubber concrete combination bridge deck slab comprises a top plate and a bottom plate with the section being in a corrugated shape, a concrete structure is arranged between the top plate and the bottom plate, the concrete structure is internally provided with a plurality of shear parts fixedly connected with the bottom plate, the shear parts are fixed to the wave trough positions of the bottom plate, the concrete structure is internally provided with first longitudinal reinforcing steel bars and first transverse reinforcing steel bars, the first longitudinal reinforcing steel bars and the first transverse reinforcing steel bars are perpendicular to each other, the first longitudinal reinforcing steel bars are located on the wave trough positions and fixedly connected with the shear parts, and the first transverse reinforcing steel bars are located on the wave peak positions. According to the corrugated steel-rubber concrete combination bridge deck slab, construction is convenient, the structure intensity is high, and driving comfortableness is high

Description

technical field [0001] The invention relates to the technical field of bridge structures, in particular to a corrugated steel-rubber concrete composite bridge deck. Background technique [0002] As an important part of the bridge structure, the bridge deck directly bears the wheel pressure of the vehicle, and its working status will directly affect the service performance and driving comfort of the bridge. Reasonable selection of the bridge deck structure is of great significance in bridge design. [0003] The inventor found that traditional bridge decks are prone to problems such as pavement damage, fatigue cracking, and insufficient local rigidity, and it is difficult to repair the steel structure after cracking, which greatly increases the cost of operation and maintenance, and the construction is more complicated. Factors such as tension and untimely maintenance often lead to cracking of the bridge deck, which in turn causes corrosion of the steel bars in the bridge deck...
