Reinforced concrete rebar connection system COUPLER GROUT

As the key technical product of prefabricated concrete structure, cementitious grout for coupler of rebar splicing is one of the patented technical products developed by SINO-SINA. FEATURE 1. Technical principle and product features CBGM series sleeve grouting materials for reinforcement connection are divided into semi grouting connection and full grouting connection according to the sleeve structure. ◆Semi grouting connection Semi grouting connection is usually that the upper reinforcement adopts straight thread, and the lower reinforcement is connected with the grouting sleeve through grouting material. It is generally used for the connection of main reinforcement of prefabricated shear wall and frame column, so the sleeve is grouting straight thread connection sleeve, which is referred to as grouting sleeve for short. ◆Full grouting connection Full grouting connection refers to the connection between reinforcement at both ends and sleeve through grouting material, which is generally used for the connection of main reinforcement of precast frame beam. Grouting connecting sleeve, hereinafter referred to as grouting sleeve 2. Construction operation process and key points 2.1 Flow chart of grouting connection installation on site PERFORMANCE 1. Features and scope of application CBGM sleeve grouting material for reinforcement connection is a cement-based grouting material specially used for reinforcement sleeve connection. This product has small aggregate particles, large fluidity, high early strength and good timeliness. It is suitable for reinforcement connection of prefabricated components of various concrete structures.
