1.Cold pressing couplers Introduction

Pressing coupler is belongs to Pressing technology used for rebar mechanical connection without threading operation; this technology is easy operation with only one oil pump and a jack and each size one mould, it is mainly using in the repair system also some special requirement working site. With higher strength rebar we will choose different kind of raw materials to meet the higher strength requirement.

2.Features and advantages

a.For repair or retrofit works

b.Fit any cold shear cut bar end.

c.No threading at ends and no reduction of the cross section Ares of the bar

3.Working Steps

a.First put one rebar ends inside of coupler and make sure it can reach half of the coupler length.

b.Pressing the couplers by cold pressing machine clamping mould.

c.Put second rebar in coupler another side and pressing it to make a full connection

4.Technical Data

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

b.Raw material

Couplers are produced by the raw material of 16Mn, Special raw material for cold pressing couplers which can keep pressing without crack and also keep the enough strength for rebar mechanical connection requirement.

C :0.13~0.19 Si :0.20~0.60 Mn :1.20~1.60 Cr≤0.30 P≤0.030 S≤0.030 Ni≤0.30 Cu≤0.25

Mechanical Properties: Yield strength≥ 315MPa, Tensile Strength: ≥470MPa
