Strong Type Upsetting Parallel Thread Rebar Couplers with Easy Installtion and High Effeciency and Cost Saving Used for High Grade Rebars

Product Detail

Product introduction:

Upsetting type rebar coupler is strong rebar parallel thread couplers which enlarge the rebar nominal diameters by cold forging and then do the thread cutting, after the thread cutting, the thread smaller diameter still larger than the rebar nominal diameter, so it is very strong connections, because of thread cutting, its threads are very smooth and it can be called easy installation rebar couplers and also it can have quick connection for rebar.

1.Strong Reba Parallel thread couplers Introduction

Rebar Upsetting Couplers is used in Upsetting technology is a parallel-thread mechanical splicing system designed for the connection of 16mm to 40mm reinforcing bars. This is easy installation rebar couplers which can make sure the quick connection for rebar. We mainly produce it by higher strength raw material 40CR

It is designed and manufactured in compliance with China standard of JGJ107-2010, UK standard of BS8110, USA standard of ACI318, VN standard of TCVN8163 and other international standards.

2.Features and advantages for this high efficiency and cost saving system:

a.No reduction of the bar cross section area and bar break feature.

b.Fast installation no need torque wrench

c.Assemble easily by visual inspection

d.It is Standard ISO parallel Metric Thread designs.

e.This mechanical connections are quicker, safer and mover convenient ways than lap splicing or welding splicing.

3.Working Steps

a.Cutting the rebar end to make it flat



b.Enlarge the rebar diameter by cold upsetting



c.Making the parallel thread by cutting



b.Connect the rebars and make sure the barbreak
