Product Description
Product introduction:Rebar pressed coupler has easy operation and higher strength for 500MPa rebar which is used in rebar splicing repaired system at the construction project site. This technology is a manual operation system for rebar mechanical connection which can easily make workers to gain the operation skills.Product details:Name:Cold pressed couplerUsed for Rebar:HRB400/Grade 65/ and so on with rebar yield strength same as 500Mpa or lower than that.Raw Material:S45C -yield strength 420Mpa, Tensile strength: 600-650MPaSize:16mm/18mm/20mm/25mm/28mm/32mm/36mm/40mmPacking:By bags and pallets packing, or wooden case packing as required (25KG smaller packing, 1700KG per pallet)Sample:Free existing samples for checking dimension and qualityProduction time:15-40 days based on different quantity after receive the prepaymentShipping Port:Xingang,Tianjin Port, Shanghai Port, China.Payment Terms:TT / LCCertificate:ISO/ CECoupler Size (mm)Out Diameter (mm)Length (mm)Weight (kg)16mm301100.33918mm341100.38020mm361200.50422mm401320.66025mm451501.03628mm501681.39032mm561922.00436mm632162.83040mm702404.1231.Cold pressing couplers IntroductionPressing 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 advantagesa.For repair or retrofit worksb.Fit any cold shear cut bar end.c.No threading at ends and no reduction of the cross section Ares of the bar3.Working Stepsa.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 connection4.Technical Dataa.Applicable Standards: JGJ107-2010, UK standard of BS8110, USA standard of ACI318, VN standard of TCVN8163 and other international standards.b.Raw materialCouplers 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≤0.25Mechanical Properties: Yield strength≥ 315MPa, Tensile Strength: ≥470MPac.Picturesd.Coupler Tensile strength comparison with common Splicing standards for Main sizes of 16mm, 20mm, 25mm, 32mm, and 40mm.Size1620253240OD (mm)3036455670Thread larger Dia (mm)20.0024.0030.2038.0046.00Coupler Cross section area (mm2)392.69565.47874.091328.852186.4816Mn Min Tensile Strength (N/mm2)470470470470470Coupler Load (KN)184.56265.77410.82624.561027.65Rebar cross-section area (mm2)201.1314.2490.9804.21257BS 8110 3.12.8.16.2 108% Fy, with 500 rebar load(KN)108.59169.67265.09434.27678.78ACI318 12.14.3.4 125%Fy(Type 1) with 500 rebar load(KN)125.69196.38306.81502.63785.63Coupler Load(KN) with BS 8110, ACI 318 requirement RemarkAboveaboveaboveaboveabove
