Description

Bridge deck connection structure and construction method Technical Field The invention relates to the technical field of bridge engineering, in particular to a bridge deck connection structure and a construction method. Background The steel-concrete combined bridge is a modern bridge type which fully exerts the mechanical property advantages of two materials of steel and concrete, and the core design idea is that two steel beams and a concrete bridge deck are combined into an integral and jointly stressed structure through reliable connecting pieces. Currently, existing bridge deck slab connection generally adopts a wet joint construction method (a plurality of bridge deck slabs are connected together by casting concrete), and the traditional construction method has the defect that a series of complex procedures are required to be carried out on a construction site by a wet joint technology. Firstly, the formwork needs to be accurately built according to the size and the joint shape of the prefabricated bridge deck, the process not only needs to consume a great deal of time and labor, but also has higher requirement on the installation precision of the formwork, otherwise, the follow-up concrete pouring quality is affected, and the quality of the site construction is affected by various factors and has larger fluctuation. In the joint or welding link of the steel bars, the defects of insufficient joint length, unstable welding and the like of the steel bars can occur due to different operation levels of constructors, and the defects can reduce the stress performance of the steel bars and influence the safety of the structure; in the process of erecting the prefabricated bridge deck, if deviation occurs in the erection position, the adjustment margin is very limited due to the fixed position of the embedded bars.
