Problems solved by technology

In addition, if the connecting steel bars of two adjacent bridge decks along the bridge direction are not considered to be staggered during prefabrication, they must be bent at a certain angle when lapping and binding on site, which increases the on-site workload of the prefabricated structure. When the pier height is large, the construction is difficult

Abstract

The invention provides a non-mold post-cast strip prefabricated reinforced concrete bridge deck slab. By improving the general structure of a prefabricated bridge deck slab, a member can be enabled toplay a role of a template so as to realize no mold. By using a mode of additionally mounting U-shaped connecting reinforcements, the connecting reinforcements of the two adjacent prefabricated bridgedeck slabs in the bridge direction can be naturally staggered in position.

Description

technical field [0001] The present disclosure relates to bridge decks in the field of construction, and in particular to a prefabricated reinforced concrete bridge deck with moldless post-casting strips. Background technique [0002] At present, the steel-concrete composite structure is a structural form in which steel members and concrete members are connected through shear connectors to produce combined forces and joint forces. When it is applied to prefabricated bridges, it is generally constructed by segmental assembly. According to the mechanical performance and construction capacity, the steel girder is divided into segments, the precast concrete bridge deck is divided into blocks, and the connection between the steel beam and the concrete bridge deck and the precast concrete Wet joints are left at the joints between the bridge decks and the structural connection measures are preset; after the steel girder segments and concrete bridge decks are prefabricated in the fac...
