Prefabricated shear wall rebar connecting joint

Abstract

A prefabricated shear wall rebar connecting joint comprises an upper prefabricated wall body, a lower prefabricated wall body and a composite floor slab. The composite floor slab comprises a composite floor slab prefabricated layer and a composite floor slab cast-in-place layer. A connecting box is embedded in the lower end of the upper prefabricated wall body. The lower end of a connecting rebar of the upper prefabricated wall body is connected with and fixed to an upper top plate of the connecting box, and the upper end of an extending rebar of the lower prefabricated wall body penetrates through the composite floor slab cast-in-place layer and a lower bottom plate of the connecting box, and finally is connected and fixed with the end of an extending rebar through a nut and a washer. According to the prefabricated shear wall rebar connecting joint, mounting and connecting of building members become quite easy, butt-joint of structural rebars extending out of the ends of the building members allows large errors, the construction difficulty is lowered, convenience, rapidness and efficiency are achieved, and the technical problem of difficult rebar butt-joint of the construction industry for years is solved; and the structure of the prefabricated shear wall rebar connecting joint adopts mechanical connection and is free of aging, high in structural strength, long in service life and good in construction quality.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and particularly relates to a prefabricated shear wall steel bar connection node. Background technique [0002] In the existing building structure system, most of the connections between building components use sleeves as steel bar connectors, such as mechanical sleeves and grouting sleeves; this sleeve connection structure makes it difficult for the steel bars protruding from the ends of the building components. Aligned with the sleeve, the construction is difficult and the efficiency is low. For example, the grouting sleeve requires high slurry preparation, and the grouting is difficult to place in place, and the slurry is easy to age and smash after a long time, resulting in loosening of the steel bars, reducing the structural strength and affecting the quality of the building; another example is the mechanical sleeve, where the ends of the building components protrude from th...
