Hlau rebaryog ib qho tseem ceeb ntawm kev tsim kho kev lag luam. Cov khoom siv ntau yam no muab lub zog thiab ruaj khov rau cov qauv pob zeb, ua rau lawv muaj zog dua thiab tiv taus kev ntxhov siab thiab hnyav. Nws yog dav siv hauv kev tsim vaj tsev, txuas hniav, txoj kev, thiab lwm yam kev tsim kho vaj tse.
Steel rebar yog ua los ntawm cov hlau, uas yog cov hlau thiab carbon. Lwm cov ntsiab lus, xws li manganese, silicon, thiab tooj liab, kuj tuaj yeem raug ntxiv los txhim kho nws cov khoom. Cov txheej txheem tsim khoom muaj kev kub-dov los yog txias-ua haujlwm cov hlau ua rau ntev, nyias tuav ntawm ntau qhov sib txawv thiab cov duab.
Steel rebar sai tau txais koob meej vim nws lub zog siab thiab ua haujlwm ntev, uas tso cai rau cov engineers tsim cov qauv siab dua thiab ntau dua. Niaj hnub no, steel rebar yog ib yam khoom tseem ceeb hauv kev tsim kho kev lag luam, thiab nws txoj kev siv yog tswj hwm los ntawm ntau cov qauv thiab cov cai kom muaj kev nyab xeeb thiab kev ntseeg tau.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm steel rebar yog nws lub zog tensile siab, uas txhais tau hais tias nws tuaj yeem tiv taus ntau qhov nro yam tsis muaj kev tawg lossis deforming. Cov cuab yeej no tseem ceeb tshwj xeeb tshaj yog nyob rau hauv cov khoom siv ntxiv dag zog, qhov twg cov rebar ua lub zog los tiv thaiv lub zog tensile uas lub pob zeb ib leeg tsis tuaj yeem dais. Steel rebar kuj muaj cov ductility zoo heev, txhais tau tias nws tuaj yeem ncab thiab khoov yam tsis muaj kev tawg, tso cai rau nws nqus lub zog los ntawm cov pob zeb nyob ib puag ncig thaum av qeeg thiab lwm yam xwm txheej seismic.
Steel rebar tuaj nyob rau hauv ntau qhov ntau thiab tsawg thiab cov duab, txhua tus tsim los rau cov kev siv tshwj xeeb. Feem ntau hom rebar muaj xws li dawb, deformed, thiab epoxy-coated rebar. Plain rebar muaj qhov chaw du thiab feem ntau yog siv rau hauv cov ntawv thov kev ntxhov siab tsawg. Deformed rebar, ntawm qhov tod tes, muaj cov tav, pob, lossis lwm yam deformations ntawm nws qhov chaw, uas muab kev tuav zoo dua thiab adhesion rau cov pob zeb ib puag ncig. Epoxy-coated rebar muaj txheej tiv thaiv ntawm epoxy txheej, uas tiv thaiv corrosion thiab ncua lub neej ntawm rebar.
Hauv kev xaus, steel rebar yog ib yam khoom tseem ceeb hauv kev tsim kho kev lag luam. Nws lub zog siab, durability, thiab ductility ua rau nws yog qhov zoo tshaj plaws ntxiv rau cov pob zeb ua vaj tse. Los ntawm kev siv steel rebar, engineers tuaj yeem tsim cov qauv siab dua, muaj zog dua, thiab ntau dua cov qauv uas tuaj yeem tiv taus ntau yam kev ntxhov siab thiab kev nyuaj siab. Raws li kev tsim kho kev lag luam txuas ntxiv mus, steel rebar yuav undoubtedly tseem yog ib qho tseem ceeb nyob rau hauv kev tsim infrastructure ntawm tag kis.
