Abstract

The invention discloses a connecting structure for vertical reinforcement bars of prefabricated wall parts. The connecting structure comprises a steel box body with an opening on one side, upper-side prefabricated part reinforcement bars fixedly connected on a top plate of the steel box body, lower-side prefabricated part reinforcement bars penetrating through the inside of the steel box body through an opening formed on the bottom side of the steel box body, base plates and nuts arranged inside the steel box body and sequentially sleeved on the lower-side prefabricated part reinforcement bars, and two wedge plates symmetrically disposed on both sides of the lower-side prefabricated part reinforcement bars. Reinforcement bar mounting holes and two parallelly arranged base plate guide grooves are formed in the base plates, wherein the base plate guide grooves are located on both sides of the reinforcement bar mounting holes. Two wedge-shaped guide grooves are parallelly formed on the lower side of the top plate of the steel box body. The base plate guide grooves and the wedge-shaped guide grooves are formed along the direction of the opening of the steel box body. The depths of the wedge-shaped grooves are gradually decreased from the opening to the inside, the upper ends of the wedge plates and the lower ends of the wedge plates are respectively embedded into the wedge-shaped guide grooves and the base plate guide grooves. By the aid of the connecting structure for vertical reinforcement bars of prefabricated wall parts, reinforcement bars of prefabricated parts are connected quickly and efficiently in real time.

Description

technical field [0001] The invention belongs to the technical field of civil engineering construction, and relates to a steel bar connection structure for vertical steel bar connection between prefabricated and assembled wall components. Background technique [0002] The prefabricated reinforced concrete structure building transforms the traditional on-site production mode into the back-field production mode, which is an important structural form for the transformation of my country's construction industrialization. The main work of the prefabricated reinforced concrete structure on site is to connect the prefabricated reinforced concrete members. The connection methods currently used can be attributed to the connection between concrete and the connection between steel bars. The steel bar connection between prefabricated reinforced concrete wall components is different from the general steel bar connection in cast-in-place reinforced concrete. It is a steel bar connection pe...
