Lub ntxaib-rib txias- dov steel bar tshuab yog ib qho tseem ceeb ntawm cov cuab yeej siv hauv kev ua haujlwm niaj hnub siv steel; nws muaj txiaj ntsig zoo, lub zog -txuag, thiab muaj peev xwm txhim kho cov khoom zoo.
Cov ntsiab lus tseem ceeb ua haujlwm
Siv cov pa roj carbon zoo tib yam steel hlau qws (kub-kub) ua cov khoom siv raw, cov khoom tau ua raws li cov kauj ruam hauv qab no:
- Txias dov rau txoj kab uas hla txo thiab tsim cov tav: Qhov no yog cov kauj ruam tseem ceeb. Ntawm qhov kub thiab txias, ib qho hnyav- lub luag haujlwm dov zeb compresses cov hlua hlau kom txo nws txoj kab (piv txwv li, los ntawm 8mm mus rau 7mm) thaum tib lub sijhawm txias- dov ob qho tib si, symmetrical transverse tav rau saum npoo. Kho qhov sib txawv ntawm yob tso cai rau kev tsim cov rebar nyob rau hauv ntau yam specifications.
- Hauv - txoj kab ncaj nraim thiab kev kho cua sov: Tom qab dov, lub rebar hla dhau ib qho passive hauv - kab ncaj nraim los xyuas kom meej. Qee cov qauv kuj tau nruab nrog siab - zaus cua sov chav nyob rau hauv - kab kev kho cua sov, uas txo cov kev ntxhov siab sab hauv thiab txhim kho lub rebar ductility.
- Txiav- mus rau- ntev: Thaum kawg, qhov tseeb servo- tsav ya shear system txiav cov rebar rau qhov ntev uas tus neeg siv khoom xav tau (feem ntau yog 1 txog 12 meters).
Cov khoom tseem ceeb nta thiab qhov zoo
- Txhim khu cov khoom zoo: Txias dov ua rau kom qhov ceev thiab lub zog ntawm rebar; tensile lub zog muaj peev xwm ncav cuag 560-565 MPa, tshaj li cov tsoos kub- dov HRB400 (Qib III) rebar.
- Txhim kho Bond Strength: Ob qhov saum npoo npoo ua rau muaj zog ntawm cov rebar thiab pob zeb ntau dua 30%.
- Cov Nqi Txuag Cov Khoom Siv: Piv nrog rau kev siv cov kab ncaj nraim, siv ribbed rebar ntawm tib cov lus qhia yuav txuag tau li ntawm 15% -20% hauv cov khoom.
- Siab -Kev Ua Haujlwm Zoo Tshaj Plaws: Cov cuab yeej siv ua ke nrog PLC (Programmable Logic Controller) thiab kov lub ntsej muag tswj, ua kom muaj kev ua haujlwm siab heev nrog kev nrawm mus txog 150 meters ib feeb.
- Kev ua haujlwm ruaj khov thiab ruaj khov: Cov khoom tseem ceeb, xws li cov yob yob, siv cov khoom siv coj los siv- cov ntaub ntawv tiv taus xws li cemented carbide, thaum lub tshuab tsav siv lub patented gearbox uas txhawb kev sib kis tau zoo ntawm 30%.
Cov Khoom Siv Tseem Ceeb
Cov ntxaib-ribbed steel tuav uas tsim los ntawm cov cuab yeej no yog cov khoom siv zoo tshaj plaws rau niaj hnub siv zog ua vaj tse thiab siv dav hauv:
Industrial thiab civil kev tsim kho
Kev nthuav dav, railways, thiab txuas hniav
Infrastructure xws li tshav dav hlau runways, tunnels, thiab dams
