Description
The USC Full-Grout Coupler is an innovative solution tailored for high-performance precast concrete connections. It integrates the precise threading of the USC JT system with the flexible adaptability of grout systems, delivering reliable, efficient and versatile connection performance for precast construction.
Featuring an integrated one-piece structure, this coupler simplifies on-site operation and greatly improves construction convenience. Optimized for extreme rebar load bearing, it adopts advanced bar break technology that exceeds mainstream industry standards.
A core advantage lies in its perfect compatibility with USC exclusive 100MPa high-strength grout. This matched system endows the coupler with outstanding resistance to harsh and rigorous construction conditions. Designed with a dual-function structure, one end connects threaded rebar while the other adopts a grout-filling design, enabling precise and flexible application in diverse precast concrete scenarios.
USC provides professional, high-quality threading support to ensure smooth and hassle-free installation for contractors. The coupler fits rebar sizes from Ø12 mm to Ø40 mm and is applicable for up to 500 MPa (60 ksi) deformed ribbed steel rebars, covering most conventional engineering requirements.
For on-site efficiency, non-shrink grout can be injected or poured into the cavity for rapid connection completion within seconds, effectively shortening construction cycles and adapting to fast-track project schedules. It performs excellently for both horizontal and vertical connections, as well as upper and lower component assembly.
Overall, the USC Full-Grout Coupler is a transformative product for precast construction. Combining high precision and wide adaptability, it upgrades the quality and efficiency of precast concrete connections for all construction projects.

Product Advantage
① Quick installation: compared with the half grouting sleeve, save the work of steel bar stripping, wire covering, tightening steel bar, convenient and efficient;The stress structure is reasonable;
② Grout end port horn design, easy to construct.
The sleeve is made by special technology with cavities at both ends, usually used for connecting the horizontal main reinforcement connection between prefabricated beams, and also suitable for the main reinforcement connection of vertical prefabricated members.
In the prefabricated components of PC plant, the steel bar can be inserted into the full grout coupler filled sleeve, eliminating the steel bar stripping, covering and tightening the steel bar, which is convenient and efficient; in the field installation, the sleeve and steel gap is relatively loose, the installation size requirements are not high, to ensure the site installation is fast and convenient, and reliable quality.
FAQ
Q: What are the benefits of working with grouted sleeves?
A: -Special process processing, less processing procedures, dimensional stability;
-Shear groove structure, the force structure is reasonable;
-Grouting end port flare design, easy to construct;
-Molded production, easy to detect, high production efficiency;
-Installation is fast: relative to the half grouting sleeve eliminates the need to strip ribs of rebar, socket wire, tightening of reinforcing steel work, convenient and efficient.
Q: Are there other types of grouting sleeves?
A: Yes, we can also provide grouting sleeves for assembled bridges, which are made of high-quality carbon structural steel with high production efficiency, solving the problem of low production efficiency of large-diameter grouting sleeves in steel machining process, and effectively avoiding defects in casting and processing process.It has the four advantages of adopting steel raw materials, tire processing, high efficiency and stable quality.
