Zoo Zoo Tuam Tshoj Siv Khoom Siv Tmt Steel Rebar rau Round Steel Rebar 12mm Hlau Qws Nqe
Peb lub hom phiaj kom nkag siab zoo disfigurement hauv kev tsim thiab muab cov kev pabcuam zoo tshaj plaws rau cov neeg siv khoom hauv tsev thiab txawv teb chaws tag nrho rau siab zoo Tuam Tshoj Siv Khoom Siv Tmt Steel Rebar rau Round Steel Rebar 12mm Hlau Qws Nqe, Ua tsaug rau koj siv lub sijhawm muaj txiaj ntsig mus rau peb thiab saib ua ntej kom muaj kev koom tes zoo nrog koj.
Peb lub hom phiaj kom nkag siab txog qhov tsis zoo ntawm kev tsim khoom thiab muab cov kev pabcuam zoo tshaj plaws rau cov neeg siv khoom hauv tsev thiab txawv teb chaws lub siab dawb paug rauTuam Tshoj Kub Rolled Steel Bar, Hlau Bar, Raws li lub Hoobkas muaj kev paub dhau los peb kuj lees txais kev txiav txim siab thiab ua kom zoo ib yam li koj daim duab lossis cov qauv kev qhia tshwj xeeb thiab cov neeg siv khoom tsim khoom.Lub hom phiaj tseem ceeb ntawm lub tuam txhab yog ua neej nyob ib tug txaus siab nco rau tag nrho cov neeg muas zaub, thiab tsim kom muaj ib tug ntev lub sij hawm yeej-yeej kev lag luam kev sib raug zoo.Yog xav paub ntxiv, xyuas kom koj tiv tauj peb.Thiab nws yog peb qhov zoo siab heev yog tias koj nyiam tuaj ntsib tus kheej hauv peb lub hoobkas.
kev faib tawm
Cov kub dov ribbed steel bar tau muab faib ua peb qib: HRB335 (qib qub yog 20MnSi), qib peb HRB400 (qib qub yog 20MnSiV, 20MnSiNb, 20Mnti), thiab qib plaub HRB500.
Muaj ob txoj hauv kev uas feem ntau siv rau kev faib cov khoom siv ntxiv:ib qho yog muab faib raws li cov duab geometric, thiab lwm qhov yog cais los yog cais raws li qhov sib txawv ntawm cov kab hla hla thiab qhov sib nrug ntawm cov tuav.Hom II.Qhov kev faib tawm no feem ntau cuam tshuam txog kev ua haujlwm ntawm lub zog ntawm lub zog.
Qhov thib ob yog raws li kev faib tawm (qib), xws li cov qauv siv tam sim no hauv kuv lub teb chaws, lub rebar yog (GB1499.2-2007) cov hlau yog 1499.1-2008), thiab cov rebar muab faib ua 3 raws li cov qib zog (yield point / tensile zog).Qib;nyob rau hauv Japanese Industrial Standard (JI SG3112), steel tuav tau muab faib ua 5 pawg raws li lawv cov khoom;nyob rau hauv British Standard (BS4461), ntau qib ntawm steel bar kev xeem ntawv kuj tau teev tseg.Tsis tas li ntawd, steel tuav tseem tuaj yeem raug cais los ntawm kev siv, xws li cov hlau zoo tib yam rau cov pob zeb ua kom muaj zog thiab cov khoom siv hluav taws xob kho cua sov rau cov pob zeb ua kom muaj zog.
yam
1) Nominal diameter ntau thiab pom zoo txoj kab uas hla
Qhov nominal txoj kab uas hla ntawm steel tuav yog li ntawm 6 mus rau 50 hli, thiab tus qauv pom zoo nominal diameters ntawm steel tuav yog 6, 8, 10, 12, 14, 16, 20, 25, 32, 40, thiab 50mm.
2) Qhov tso cai sib txawv ntawm cov duab saum npoo thiab qhov loj ntawm ribbed steel bar
Cov qauv tsim ntawm ribbed steel tuav yuav tsum ua tau raws li cov hauv qab no:
Lub kaum sab xis β nruab nrab ntawm txoj kab nruab nrab ntawm txoj kab nruab nrab thiab cov hlau bar axis yuav tsum tsis txhob tsawg dua 45 degrees.Thaum lub kaum sab xis tsis siab tshaj 70 degrees, cov kev taw qhia ntawm txoj kab hla ntawm ob sab ntawm cov hlau bar yuav tsum yog qhov sib txawv;
Qhov nominal spacing l ntawm cov kab hla hla yuav tsum tsis txhob ntau tshaj 0.7 npaug ntawm nominal txoj kab uas hla ntawm tuav;
Lub kaum sab xis α nruab nrab ntawm sab ntawm txoj kab nruab nrab ntawm txoj kab nruab nrab thiab qhov chaw ntawm cov hlau yuav tsum tsis pub tsawg dua 45 degrees;
Qhov sib npaug ntawm qhov khoob (suav nrog qhov dav ntawm qhov ntev ntawm cov tav) ntawm qhov kawg ntawm cov kab hla hla ntawm ob sab ntawm cov hlau bar yuav tsum tsis txhob ntau tshaj 20% ntawm qhov nominal perimeter ntawm steel bar;
Thaum lub nominal txoj kab uas hla ntawm lub steel bar tsis ntau tshaj 12 hli, tus txheeb ze tav cheeb tsam yuav tsum tsis txhob tsawg tshaj li 0.055;Thaum lub nominal txoj kab uas hla yog 14mm thiab 16mm, qhov txheeb ze tav cheeb tsam yuav tsum tsis txhob tsawg tshaj li 0.060;thaum lub nominal txoj kab uas hla yog ntau tshaj 16 hli, tus txheeb ze rib cheeb tsam yuav tsum tsis txhob tsawg tshaj li 0.065.Saib Daim Ntawv Ntxiv C rau kev suav ntawm thaj tsam ntawm tus tav.
Ribbed steel tuav feem ntau muaj longitudinal tuav, thiab kuj muaj cov uas tsis muaj longitudinal tuav;
3) Ntev thiab tso cai sib txawv
Ib.ntev
Cov hlau tuav feem ntau yog xa mus rau qhov ntev, thiab qhov tshwj xeeb xa khoom ntev yuav tsum tau qhia hauv daim ntawv cog lus;
Cov hlau tuav tuaj yeem xa tuaj rau hauv yob, txhua yob yuav tsum yog ib lub steel bar, thiab 5% ntawm cov yob ib batch (tsawg dua ob yob yog ob yob) muaj ob lub steel tuav.Qhov hnyav disk thiab txoj kab uas hla yog txiav txim siab los ntawm kev sib tham ntawm tus neeg muag khoom thiab tus neeg yuav khoom.
b.Ntev ntev
Thaum lub sij hawm tas sij hawm xa tuaj, qhov kev sib txawv ntawm qhov ntev ntawm lub steel bar tsis ntau tshaj ± 25mm;
Thaum qhov tsawg kawg nkaus yuav tsum tau, qhov sib txawv yog +50mm;
Thaum qhov ntev tshaj plaws yuav tsum tau, qhov sib txawv yog -50mm.
c.Curvature thiab xaus
Qhov kawg ntawm steel bar yuav tsum tau txiav ncaj, thiab lub zos deformation yuav tsis cuam tshuam rau kev siv
duab nthuav qhia
