Wet joint connecting structure of precast concrete bridge deck slab and construction method

Abstract

The embodiment of the invention discloses a wet joint connecting structure of a precast concrete bridge deck slab. The wet joint connecting structure comprises precast concrete bridge deck slabs andsteel plates. The steel plates are fixedly connected to the end faces of transverse sides of the precast concrete bridge deck slabs. Each precast concrete bridge deck slab comprises a vertical face. The steel plates are attached to the vertical faces, the upper and lower ends of the steel plate exceed the vertical faces; the two steel plates located between the vertical faces of every two adjacentprefabricated concrete bridge deck slabs are attached to each other. The portions, located at the lower ends of the vertical faces, of the two steel plates are fixedly connected, the portions, located at the upper ends of the vertical faces, of the two steel plates are fixedly connected, connecting grooves are jointly defined by the upper ends of the butt joint positions of every two adjacent prefabricated concrete bridge deck slabs, and the fixed connecting positions of the two steel plates are poured into the connecting grooves through concrete. According to the embodiment of the invention,the on-site assembly is convenient and fast, the template-free construction is completely realized, the tedious working procedures of on-site template mounting and dismounting are avoided, and the characteristics of small on-site pouring amount and high construction efficiency are realized.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a prefabricated concrete bridge deck wet joint connection structure and a construction method. Background technique [0002] Composite structure bridges have the economy of overall stress, the rationality of giving full play to the advantages of steel and concrete's respective material properties and making up for their respective shortcomings, and the outstanding advantages of being convenient for construction. It has become a major development direction for the development of bridge technology in China. broad. [0003] The connection structure of the prefabricated bridge deck in the composite structure bridge is the part with the weakest force and the construction is relatively complicated. The wet joints of the conventional prefabricated bridge deck are mostly constructed by ring-shaped steel bar lapping and hanging formwork. The construction process is cumbersome, ...
