Upset forging Threaded rebar coupler, also known as the names rebar connectors, rebar splicing, mechanical rebar couplers is a joint of steel bars on a parallel line which is designed for reinforcement bars and usually used in conjunction with rebar threading machine.
Rebar couplers are used in reinforced concrete structures to replace normal rebar lap joints.
This type of rebar coupler belongs to upset forging technology.
Upsetting type rebar couplers are parallel thread couplers that can enlarge the minimal diameters of a piece of rebar by cold forging them and then cutting the thread.
It is designed and manufactured in compliance with USA standard of ACI318, UK standard of BS8110, China standard of JGJ107-2010 and other international standards.
Features and advantages
1-It can connect steel bar diameter from 16mm to 40mm.
2- This upset forging splicing technology can not reduce of rebar cross sectional area, Upset forging parallel thread steel bar coupler can make sure 100% Bar Break Performance
3-Easy and fast installation , No need torque wrench.
4-High efficiency and Cost saving way
5-Much safer and quicker than lap splicing or welding splicing.
Processing Steps
(1) Enlarging ends of reinforced bars by cold upsetting (Rebar Upset forging Machine )
(2) Threading parallel threads by Rebar Thread Cutting Machine
(3) Splicing rebar by upsetting threaded rebar coupler
