CHEERON threadbar connection system is a mechanical coupling solution designed specifically for connecting post-tension steel reinforcement ends in concrete structures such bridge engineering.
Designed for efficiency, this coupler features rib peeling and parallel thread rolling, offering stable, high-strength connections with minimal material waste.
Cold-forged threaded couplers connect to steelbars with upset and threaded ends, ensuring ultra-high strength mechanical splicing and are widely used in high-rise building projects.
Connects rebars of different diameters, using parallel or taper transition threaded couplers for versatile, full-strength joints in complex building structures with high precision.
One end has internal tapered/parallel thread, the other end has arc-shaped welding interface. Weldable couplers offer robust connections between reinforcement and steel plates, ideal for composite steel-concrete structures.
The couplers have excellent alignment and enable rapid installation in confined spaces. Taper threaded couplers provide a high-strength mechanical splicing for reinforcement.
These are position couplers that use opposite threads at both ends to create mechanical splices of non-rotatable bars. And easy alignment in narrow construction.
Equipped with a lock nut, this type of positional coupler ensures secure, non-rotatable bar splice, distributing pressure evenly for enhanced building structural integrity.
Innovative split design allows easy installation in constrained spaces, ensuring reliable, high-strength rebar connections for complex concrete structures.
High-strength dodecagonal design maximizes torque resistance, offering superior durability and secure connections for critical reinforced concrete applications.
Galvanized Rebar Couplers with hot-dip zinc coating deliver excellent corrosion and rust resistance. Strong, reliable connections that significantly boost construction efficiency and structural safety.
Corrosion-resistant epoxy coating enhances durability, providing reliable, high-strength rebar connections for harsh environments while maintaining structural integrity.
Threaded rebar couplers, also known as threaded mechanical couplers, are mechanical splicers used to transmit axial tensile forces on rebars.
Its principle is to properly tighten the coupler's internal thread and rebar's external thread to provide sufficient friction to transmit force, thus completing the mechanical splicing of two reinforcing bars.
Cheeron threaded rebar couplers types can be broadly categorized into two thread types, four rebar connection scenarios, and three processing requirements.
Parallel threaded couplers have a cylindrical internal thread with a consistent diameter from beginning to end. Taper threaded sleeves have a tapered internal thread. The thread diameter gradually decreases from the end to the inside.
While parallel and taper threaded couplers both transmit force through thread engagement, but they differ significantly in sleeve design, rebar processing technology, joint performance, and ease of construction.
1. Standard Type: Requires connecting two rebars of the same diameter, e.g., standard rebar connectors.
2. Transition Type: Requires connecting two rebars of different diameters, e.g., Reducing rebar couplers.
3. Positioning Type: Requires connecting one or two non-rotating rebars, e.g., left and right threaded coupler; lock nut rebar couplers; split rebar couplers.
4. Weldable Type: Requires connecting steel plates and rebar.
Higher Connection Strength : Upset Reinforced Rebar Sleeves
Special Shape Requirements: 12-Angle Rebar couplers
Corrosion Protection : Galvanized Threaded Coupler; Epoxy Resin Rebar Sleeves
These attributes can be combined. For example, epoxy resin straight thread reducer connectors. Tell us your needs and we will customize it for you.
Threaded couplers outperform traditional joints, ensuring stronger rebar splicings, eliminating weak welds.
Threaded mechanical couplers for bars solve problems such as alignment errors and reducing rebar congestion.
1.Threaded couplers for rebars ranging from 12mm to 50mm( #4 to #14). For large-diameter reinforcement, matching accuracy is higher.
2. Using Cheeron rebar threading machine allows for the prefabrication of rebar threads in factory, significantly improving installation efficiency.
3. The cost of a single ordinary threaded reinforcement coupler is significantly lower than other types of a single mechanical coupler.
4. Threaded rebar splicing is the most diverse type of rebar connection. Solving complex construction requirements for engineers and contractors.
Threaded rebar available in sizes from 12mm to 50mm (#4 to #14 rebar) with adjustable thread pitches (2.5-5mm) to suit unique project demands.
Using Rebar Thread Rolling Machine to form precise, uniform grooves for enhanced bonding.
Threaded rebar meets Type 2 international standards and passes rigorous tensile tests, ideal for earthquake-resistant structures.
