Rebar, feem ntau hu uahlau, ua lub luag haujlwm tseem ceeb hauv kev tsim kho, muab lub zog tensile uas xav tau los txhawb cov qauv pob zeb. Hom hlau xaiv rau ib qhov project feem ntau nyob ntawm nws qib zog thiab daim ntawv thov tshwj xeeb, yog li cov engineers thiab cov neeg ua vaj tse yuav tsum paub txog cov yam no.
Muaj ntau hom hlau rebar, txhua hom tsim los rau ib qho kev siv tshwj xeeb. Cov hom feem ntau suav nrog:
1. Cov hlau rebar me me(Chav Kawm 40): Hom no muaj lub zog tso zis ntawm 40,000 psi thiab feem ntau siv rau hauv cov haujlwm nyob hauv tsev xws li txoj kev tsav tsheb thiab txoj kev taug kev. Nws qhov kev hloov pauv ua rau nws yooj yim khoov thiab tsim.
2. Cov hlau muaj zog heev(Qib 60): Cov hlau no muaj lub zog tso zis ntawm 60,000 psi thiab tsim nyog rau kev siv lag luam thiab kev lag luam, suav nrog cov tsev siab thiab Choj. Qhov nce ntxiv ntawm nws lub zog tuaj yeem txo qhov kev siv cov ntaub ntawv yam tsis cuam tshuam rau kev ncaj ncees ntawm cov qauv.
3. Cov hlau nplaum uas muaj epoxy txheej: Hom no yog txheej nrog epoxy los tiv thaiv kev xeb, ua rau nws zoo tagnrho rau cov qauv uas raug rau qhov chaw ib puag ncig hnyav, xws li kev siv Marine lossis thaj chaw uas muaj av noo siab.
4. Stainless hlau rebar: Cov hlau tsis xeb yog lub npe hu rau nws qhov kev tiv thaiv corrosion zoo tshaj plaws thiab siv rau hauv cov chaw muaj corrosion siab xws li cov chaw tsim tshuaj lom neeg thiab cov qauv ntug dej hiav txwv.
Qib kev siv zog thiab nws qhov tseem ceeb:
Qib zog ntawm cov hlau rebar yog qhov tseem ceeb los txiav txim siab nws lub peev xwm. Cov qib siab dua, xws li qib 75 lossis 80, muab lub zog tensile siab dua, ua rau nws tsim nyog rau kev siv hnyav. Kev xaiv qib zog cuam tshuam ncaj qha rau kev tsim qauv thiab kev nyab xeeb ntawm cov qauv vim nws cuam tshuam rau qhov ntau ntawm cov khoom thauj uas cov hlau tuav tuaj yeem txhawb nqa.
Xaus lus, kev nkag siab txog ntau hom rebar thiab lawv cov qib zog sib xws yog qhov tseem ceeb rau kev xaiv cov khoom siv zoo rau txhua qhov project tsim kho. Los ntawm kev xav txog cov ntawv thov tshwj xeeb thiab cov xwm txheej ib puag ncig, cov neeg tsim kho tuaj yeem ua kom lub neej ua haujlwm thiab kev nyab xeeb ntawm lawv cov qauv.
