Bolted rebar couplers muab tag nrho - zog txhua yam splice rau reinforcing tuav yam tsis muaj threading, swaging, los yog welding lub rebar xaus. Kev sib txuas yog nyob ntawm siab - lub zog shear bolts uas nkag mus rau hauv qhov chaw bar thiab ib qho kev tuav sab hauv hauv lub tes tsho steel. Qhov kev tsim no tso cai rau kev teeb tsa sai ntawm cov chaw ua haujlwm uas siv cov txheej txheem cuam tshuam rau wrenches, ua rau nws tsim nyog rau cov pob zeb retrofits, pawg hau kev sib txuas, thiab congested rebar tawb qhov twg bar tig los yog teb threading yog impractical.

Cov yam ntxwv tseem ceeb ntawm cov khoom

Tsis muaj Rebar End Npaj:Kev teeb tsa ncaj qha rau ntawm lub tiaj -txiav, nplaim taws- txiav, lossis sheared bar xaus, tshem tawm tawm -site threading lossis txias-forging logistics.

Calibrated Shear Bolt Lub Taub Hau:Hex taub hau txiav txiav tawm ntawm lub hom phiaj torque pib, xyuas qhov pom kev zoo tswj tsis tau phau ntawv torque ciaj ntswj auditing.

Internal Serrated Profile:Precision-machined sab hauv grooves tom rau hauv rebar nto nrog rau bolt indentation, tiv thaiv micro-slippage nyob rau hauv dynamic load cycles.

Bar Rotation Dawb:Kev ywj pheej qhov chaw tso cai tso cai rau kev sib txuas ntawm ob qhov ruaj khov, khoov, lossis kos cov kab tsis muaj kev sib hloov ob ntu.

Compact Outer Txoj kab uas hla:Minimized phab ntsa thickness xyuas kom ua raws li cov qauv kev cai npog npog thiab txo qhov kev tsis sib haum xeeb hauv cov qauv nruj.

FAQ

Q: Cov couplers puas tuaj yeem ntsia tau rau ntawm khoov lossis nkhaus rebar?

A: Yog, muab qhov ncaj embedded seem nkag mus rau hauv lub coupler ua tau raws li qhov tsawg kawg nkaus qhov tob cim rau ntawm lub tes tsho.

Q: Cov cuab yeej twg yuav tsum muaj nyob rau ntawm qhov chaw?

A: Txheem coj mus muag cuam tshuam wrenches lossis tes ratchets. Tsis muaj cov khoom siv hydraulic swaging, xov- txiav tshuab, lossis lub tshuab fais fab rau vuam yog xav tau.

Q: Yuav ua li cas cov neeg soj ntsuam paub meej tias qhov tseeb torque tom qab kev teeb tsa?

A: Cov neeg soj ntsuam pom pom tseeb tias txhua lub taub hau shear tau tawg tawm huv ntawm lub tes tsho flange nto. Tsis muaj phau ntawv torque wrench xyuas yog yuav tsum tau.

Q: Cov couplers no puas haum rau epoxy-coated rebar?

A: Yog lawm, tab sis cov txheej txheem epoxy nyob rau hauv qhov txuas txuas txuas ntev yuav tsum tau muab txhuam los yog xaim - txhuam tawm ua ntej kev teeb tsa kom cov lus qhia cov ntsia hlau tawv tuaj yeem tom ncaj qha rau hauv cov hlau hauv qab.

Q: Dab tsi yog qhov ntsuas hluav taws xob tiv thaiv rau cov khoom siv tshuab no?

A: Thaum embedded rau hauv pob zeb, lub coupler tswj kev ncaj ncees sib npaug zos rau lub ntsiab rebar nyob rau hauv lub pob zeb npog hluav taws cov lus qhia (piv txwv li, EN 1992-1-2). Lub tes tsho nthuav tawm tuaj yeem muab nrog hluav taws-retardant txheej qhwv thaum thov.

Q: Lub coupler puas tuaj yeem raug tshem tawm lossis rov siv dua tom qab lub taub hau ntsia hlau txiav?

A: Tsis yog. Cov shear bolts yog ib qho ruaj khov - siv cov khoom sib txuas. Kev sim thim rov qab snapped bolts puas tsuaj rau rebar indentation thiab cuam tshuam cov neeg kho tshuab kev ncaj ncees.
