Quantitative-type grouting device of sleeve of PC component and with reinforcement positioning and sealing functions

Abstract

The invention discloses a quantitative-type grouting device of a sleeve of a PC component and with reinforcement positioning and sealing functions, relates to the technical field of sleeve grouting, and solves the problem of difficult control of grouting amount in the grouting process of an existing sleeve and poor positioning and sealing effects of the sleeve for a reinforcement. The quantitative-type grouting device of the sleeve of the PC component and with reinforcement positioning and sealing functions comprises a sleeve main body, a grouting port is formed in the outer side of the sleevemain body, a slurry outlet is formed above the grouting port, and a grouting pipe mechanism is mounted on the outer side of one end of the slurry outlet and comprises a slurry inlet pipe, a connecting circulating pipe, a blocking rod, a connecting protective sleeve, a connecting pipe, a fixed blocking seat, a regulating plate, a rotary handle and a slurry outlet pipe. According to the quantitative-type grouting device, centering and positioning can be conducted on a connecting reinforcement in the sleeve, quantitative-type grouting operation and slurry sealing can be conducted on the sleeve,the control of grouting amount and accurate positioning of the reinforcement can be achieved, and the connection quality of the sleeve is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of sleeve grouting, in particular to a PC component sleeve quantitative grouting device with steel bar positioning and sealing functions. Background technique [0002] With the rapid development of social economy, prefabricated concrete structures are becoming more and more popular in the market. The obvious difference in form between prefabricated concrete structures and cast-in-place concrete structures is the discontinuity of concrete and steel bars at the seams caused by component division and prefabrication. Truncated, prefabricated concrete structure PC member reinforcement connection mainly adopts sleeve grouting connection technology, the disconnected steel bars of PC components are butt-connected through special steel sleeves, and the space between the steel bars and the sleeve cavity is filled with micro-expansion, high-strength Grouting material to form the rebar sleeve grout connection, the sleev...
