1.Standard rebar couplers Introduction

Standard rebar coupler is belongs to Rolling technology, it is a parallel-thread mechanical splicing system used for the 16mm to 40mm reinforcing bars mechanical connections. This system is first peeling the rebar rib and then doing thread by cold rolling, this technology can meet with China standard of JGJ107-2010, USA standard of ACI318, UK standard of BS8110, VN standard of TCVN8163 and other international standards. The couplers can divided into standard couplers with all right hand thread, and also positional rebar coupler with one side left hand thread another size right hand thread, also it has transition couplers which two sides has different diameters. Also this coupler has competitive price than super couplers and suitable for little lower rebar grade such as HRB400 or HRB500 rebar, it has full sizes from 16mm to 40mm.

2.45# steel carbon steel rebar couplers Features and advantages

a.Saving cost and easy operation than lapping of rebar

b.One time loading can finish the rib peeling and thread rolling together.

c.Single step process, only one machine, one operator.

d.Assemble by visual inspection

e.Standard ISO parallel Metric Thread designs.

f.Used for many kind of connections for position or transition couplers

3.How it operating the machine and rebar

a.Cutting the rebar end to make it flat



b.Peeling the rebar ribs



c.Rolling the rebar ends after peeling the ribs



d.Make the connection and doing the test show.



4.How these couplers are using at the working site

a.Splicing method as below:

     

Standard splicing                                                       Position Splicing 1

       

Position Splicing 2                                                Transition Splicing

b.Typical applications

    

Column                                                                    Bored Piles

       

Waiting Rebar                                                         Wall, Shell

                     

                                                      Beam

5.Technical Data

a.Applicable Standards: JGJ107-2010, UK standard of BS8110, USA standard of ACI318, VN standard of TCVN8163 and other international standards.

The couplers are strictly under production tested by the thread gauge and calipers.

b.Raw material

Couplers are produced by the raw material of 45 carbon steel, correspond to international standards of JIS: SCr440, ASTM: 5140, ISO: 41Cr4.

Chemical composition: C:0.42~0.50    Si:0.17~0.37   Mn:0.50~0.80   Cr: =0.25%  Ni:=0.30  P:=0.025

Mechanical Properties: Yield strength= 355MPa, Tensile Strength: =600MPa.
