Full Grout Filled Sleeve for Precast Concrete Connection

Full Grout Filled Sleeve for Precast Concrete Connection is a key rebar splicing technique in precast concrete, offering structural continuity and integrity through mechanical connections within grout-filled sleeves. It is versatile for various constructions, with models like GTZQ4 accommodating rebar diameters from 12mm to 40mm. The technology ensures full tension transfer, is user-friendly, meets high strength standards, and is environmentally sound. Research supports its reliability and performance under diverse conditions, including high temperatures and with UHPC grout, highlighting its potential in advanced concrete applications.

product details

Full Grout Filled Sleeve for Precast Concrete Connection is a reinforcing bar connection technique used in precast concrete structures. This type of connection realizes the mechanical connection of reinforcement bars by filling high-strength grout inside the sleeve, thus providing structural continuity and integrity. It is widely used in construction, roads, bridges and other projects, especially for the connection of precast concrete elements.

Features and Benefits:

1. full rebar breaking performance: full Grout Filled Sleeve is capable of full tension transfer and rebar breaking in tensile testing.

2. Convenience and Flexibility: Easy to use, high productivity and fast installation.

3. High tensile and yield strength: meet JGJ107, JG/T398 and other standards.

4. Environmental protection: safe connection process, friendly to the environment.

5. Reliability: According to the study, the reliability of this connection depends on the bond strength between the reinforcement bars and the grouting material, and the study also proposes the minimum anchorage length for different types of reinforcement bars.

In addition, studies looking at the mechanical properties of the Full Grout Filled Sleeve at elevated temperatures, as well as experimental studies using Ultra High Performance Concrete (UHPC)-grouted sleeves for connecting large deformed reinforcement bars, have further validated the performance and application potential of the Full Grout Filled Sleeve under different conditions.
