Swaged Rebar Couplers muab tag nrho - lub zog txhua yam splice los ntawm txias -forging lub tes tsho seamless steel ncaj qha mus rau ribbed reinforcement steel. Siv lub tshuab hluav taws xob hydraulic swaging xovxwm, lub tes tsho steel deforms plastically rau hauv lub rebar tav, tsim kom muaj kev sib txuas ntawm cov neeg kho tshuab uas tshaj qhov kawg tensile lub zog ntawm niam txiv bar.

Cov kab ke no tshem tawm cov xov teb, bar- cua sov kawg, thiab hla- ntu ntu txo qis. Nws txuas tus qauv deformed rebar (# 4 mus rau # 18 / 12mm rau 57mm) nyob rau hauv siab -seismic, siab- qaug zog, thiab congested pob zeb cov qauv uas tsoos lap splices ua rau steel congestion los yog ua tsis tiav code clearance txwv.

Cov yam ntxwv tseem ceeb ntawm cov khoom

Zero Threading Yuav Tsum Tau:Koom nrog shear-txiav lossis nplaim taws- txiav rebar ncaj qha yam tsis muaj xov txiav, txias- chim siab, lossis taper machining.

Tag nrho Mechanical Interlock:Txias radial deformation quab yuam lub tes tsho hlau rau hauv rebar deformations, tshem tawm plam hauv kev thauj mus los.

100% Bar Break Assurance:Splice tsim muaj peev xwm tshaj qhov kawg tensile lub zog (fu) ntawm Qib 60, Qib 75, thiab Qib 80 rebar.

Compact Outer Txoj kab uas hla:Sleek lub tes tsho profile txo cov rebar tawb congestion, enabling smooth qhob tso thiab aggregate txaus.

Visual Inspection Peev Xwm:Ua tiav qhov txias txias-swaging ua rau ntsuas qhov ntsuas sab nraud txo qis thiab lub tes tsho elongation, tso cai ntsuas ntsuas ntsuas tam sim ntawm qhov chaw.

FAQ

Q: Yuav ua li cas yog ib tug swaged coupler txawv ntawm ib tug parallel threaded coupler?

A: Swaged couplers yuav tsum tsis muaj bar - xaus threading los yog chim siab. Lub hydraulic xovxwm deforms lub tes tsho mus rau raw rebar tav ntawm -site, txuag tawm - site machining zog thiab ua hauj lwm ntawm crooked los yog sheared bar xaus.

Q: Puas siv tau swaged couplers nyob rau hauv siab -seismic zones?

A: Yog. Peb swaged couplers txaus siab ACI 318 Hom 2 thiab ISO 15835 S1 cov kev cai, xa tag nrho tensile thiab compressive muaj peev xwm tshaj 100% ntawm lub bar qhov kawg lub zog (fu) nyob rau hauv dynamic strain.

Q: Cov khoom siv ntawm qhov chaw puas xav tau rau kev teeb tsa?

A: Yog. Kev txhim kho yuav tsum muaj lub tshuab nqa nqa nqa hydraulic swaging nruab nrog cov khoom tuag txuam nrog koj lub hom phiaj bar diameters. Peb muab cov khoom siv rau kev muag khoom lossis xauj nrog rau kev txiav txim txuas ntxiv.

Q: Peb puas tuaj yeem splice ob txoj kab sib txawv?

A: Yog. Peb tsim cov kev hloov pauv swaged couplers tsim nrog cov kauj ruam hauv bores los koom nrog qhov sib txuas rebar qhov ntau thiab tsawg yam tsis tas yuav tsum tau ntxiv cov phaj adapter.

Q: Yuav ua li cas cov kws tshuaj ntsuam xyuas xyuas kom zoo swaging zoo?

A: Cov neeg soj ntsuam siv lub siab GO/NO-GO lub nplhaib ntsuas los ntsuas lub tes tsho txo txoj kab nruab nrab ntawm ncej- swaging. Kho txoj kab uas hla sab nrauv txo qhia tag nrho cov hlau - mus rau - tav mechanical interlock.

Q: Puas yog swaged couplers siv tau nrog epoxy-coated rebar?

A: Yog. Peb muab swaged couplers configured rau coated rebar, tab sis tuag pressures tej zaum yuav raug kho me ntsis kom them nyiaj rau txheej thickness thaum ua raws li cov txheej txheem ACI plam.
