Weldable Rebar Couplers txuas cov hlua txuas ncaj qha rau cov qauv hlau, nrog rau cov kab hlau, cov kaus mom, caissons, thiab cov phaj embedment. Tsim los nrog rau sab nraud bevel-txiav lub xub pwg rau tag nrho cov txheej txheem kev sib txuas, ib kawg koom nrog cov qauv hlau thaum cov xov sib txuas sab hauv tau txais cov xov rebar ntawm qhov chaw. Qhov kev sib txuas tshuab no hloov ob - taub hau studs thiab ntev lap splicing, tshem tawm steel congestion thaum kis tag nrho nro thiab compression loads nyob rau hauv cov qauv ciam teb.

FAQ

Q: Cov couplers puas tuaj yeem welded rau cov qauv hlau yam tsis muaj ua ntej - cua sov?

A: Ua ntej- cua sov nyob ntawm qhov sib npaug ntawm cov pa roj carbon sib npaug (CEV) ntawm cov qauv steel puag phaj thiab qhov kub thiab txias. Vim tias cov khoom sib txuas siv qis - carbon steel (C<= 0.22%), standard AWS D1.1 pre-heat guidelines apply based on plate thickness rather than coupler chemistry.

Q: Puas yog vuam cua sov puas degrade lub internal parallel threads?

A: Tsis yog. Internal xov geometry tseem tsis cuam tshuam thaum vuam tsis raug. Thaum tshav kub kub dissipation tshwm sim los ntawm cov phab ntsa hnyav. Tsis txhob muab cua sov nyob ze ntawm lub cev threaded qaum cheeb tsam.

Q: Cov couplers no puas tsim nyog rau cov xwm txheej dynamic lossis seismic load?

A: Yog. Thaum ua ke nrog threaded rebar kom raug, cov couplers ua tiav ACI 318 Hom 2 kev ua tau zoo, uas yuav tsum muaj kev txhim kho tensile tag nrho tsim nyog rau seismic tsim pawg A txog F.

Q: Peb puas tuaj yeem siv tus qauv tapered xov rebar nrog cov couplers?

A: Tsis yog. Cov couplers no muaj qhov ncaj / sib luag metric lossis imperial threads. Rebar kawg yuav tsum yog tib yam - xov (ntawm txias- forging los yog threading machinery) kom ntseeg tau tias cov khoom thauj khoom sib txawv thoob plaws txhua txoj xov.

Q: Dab tsi vuam hlau lossis electrode yuav tsum siv rau ntawm qhov chaw?

A: Tsawg-hydrogen SMAW electrodes (xws li E7018) los yog sib piv GMAW/FCAW hlau tsim rau carbon steel vuam raws li AWS D1.1/D1.4 qauv raug pom zoo.

Q: Dab tsi yog tus qauv coj mus kuaj thiab ntim hom rau kev txiav txim xa tawm?

A: Qhov ntau thiab tsawg (#4 txog #11) nkoj hauv 15-20 hnub. Couplers yog oiled, capped nrog tiv thaiv yas plugs, thawv, thiab ntim rau ntawm fumigated ntoo pallets los yog nyob rau hauv steel-reinforced crates.
