Full Grouting Sleeves for Prefabricated Building Reinforcement Connections

Abstract

The invention discloses a whole grouting coupler for rebar splicing of a prefabricated building. The whole grouting coupler comprises a first grouting coupler body and a second grouting coupler body and an eccentric joint for splicing the two grouting coupler bodies, wherein the first grouting coupler body and the second grouting coupler body are located on two sides; an annular groove, a first sealing and clamping sheet and a grouting hole are arranged at one end of the first grouting coupler body; an inner cone is arranged at the other end of the first grouting coupler body, and a screw sleeve is arranged on the outer side, corresponding to the first grouting coupler body, of the inner cone section; the eccentric joint comprises a middle disc as well as a first frustum and a second frustum which are located on two sides of the middle disc and arranged in a mutual eccentric manner, and a through grout discharging hole is formed in the center of the first frustum; the second grouting sleeve body adopts the same structure with that of the first grouting sleeve body and is matched with second frustum. An eccentric distance is formed between the two frustums on the middle disc, the problem of deviation of prefabricated members during hoisting and mounting is solved, and the construction process becomes simple and easy to implement.

Description

technical field [0001] The invention relates to the technical field of connection construction of prefabricated concrete components of prefabricated concrete structures, in particular to a sleeve grouting connection structure of transverse steel bars in prefabricated concrete structures. Background technique [0002] At present, prefabricated concrete structures are constructed using industrial technology, and their main structural parts are prefabricated in factories. After arriving at the site, these prefabricated concrete components are installed and connected into a whole. This industrial production method greatly reduces the amount of wet work on the construction site. , significantly increased the construction speed, reduced environmental pollution and material consumption, and has become a new direction for the development of my country's construction industry. The steel bar connection of prefabricated concrete structures is the key to the structural safety. The steel ...
