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 composite bridge deck, comprising a top plate and a bottom plate with a corrugated cross-section, a concrete structure is arranged between the top plate and the bottom plate, and a plurality of bridges fixedly connected with the bottom plate are arranged inside the concrete structure. A shear member, the shear member is fixed at the position of the trough of the bottom plate, a first longitudinal reinforcement and a first transverse reinforcement perpendicular to each other are arranged inside the concrete, and the first longitudinal reinforcement is located above the trough of the bottom plate and is connected to the The shear members are fixedly connected, and the first transverse steel bar is located above the wave crest of the bottom plate. The bridge deck of the present invention is convenient in construction, high in structural strength, and high in driving comfort.

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...
