Kub-Ribbed Steel Tuav

Rebar yog lub npe nquag rau kub-rolled ribbed steel kab. Cov qib ntawm dog dig kub-yob steel bar muaj ntawm HRB thiab qhov tsawg kawg ntawm cov qib kawm. H, R, thiab B yog thawj tus ntawv Askiv ntawm peb lo lus, saib nws tus kheej, thiab tuav duav, feem ntau. Kub-Ribbed Steel cov tuav tau muab faib ua peb qib: Qib yog 20mns (20mnsinb, 20mnti) thiab HRB500.

Lub ntsiab

Nplua-grained kub-rolled steel bar thawj tsab ntawv Askiv (zoo) ntawm "zoo" yog ntxiv rau lub npe ntawm lub npe kub Ribbed steel bar. Zoo li:
HRBF335HRBF400, HRBF500. Cov qib muaj txiaj ntsig rau cov qauv seismic nrog cov kev xav tau dua yog: ntxiv e tom qab cov qhab nia uas twb muaj lawm (piv txwv li: HRB400E
HRBF400E)
Kev siv lub ntsiab: dav siv hauv kev tsim kho pej xeem siv xws li tsev, txuas hniav, thiab lwm yam.
Qhov sib txawv ntawm rebar thiab puag ncig bar: qhov sib txawv ntawm rebar thiab puag ncig ribs thiab ntau dua nrog ob lub tsheb ciav hlau ntev thiab hloov pauv ntawm qhov ntev. Rebar yog ib seem me me hlau, tsuas yog siv rau pob txha ntawm kev txhawb nqa qhob cov vaj tse sib. Hauv kev siv, tej yam zog tshuab zog, khoov deformation kev ua tau zoo thiab cov txheej txheem vuam ua tau zoo. Cov khoom siv cov khoom siv rau kev tsim cov rebars yog cov hlau txheem cov hlau txheem steel lossis tsawg-alloyed qauv txheej txheem hlau kho los ntawm kev tshuaj lom.
Cov qauv hlau, cov txheej txheem ua tiav steel kab tau xa tawm hauv cov kub-dov, ib txwm muaj lossis kub.

ntaus

Muaj ob txoj hauv kev feem ntau rau cov rebar; Ib qho yog cais los ntawm geometric puab, thiab faib lossis cais raws cov duab hla kev ntawm cov tav.
Hom, xws li tus qauv Askiv (BS4449), Rebar tau muab faib ua | Hom, Kuv ntaus. Qhov kev faib tawm no tsuas yog xav txog kev ua tau zoo ntawm cov rebar. Ob tug yog
Kev Ua Haujlwm Kev Ua Haujlwm (qib), xws li kuv lub teb chaws txoj kev siv tam sim no (GB1499.2-2007), raws li lub zog qib
Txawv (tawm tsam taw tes / tensile lub zog), tus rebrar faib ua 3 qib; Nyob rau hauv Japanese kev lag luam qauv (JISG3112), Rebar tau muab faib ua 5 hom raws li kev ua tau zoo; Nyob rau hauv tus qauv Askiv (BS4461), Rebrar tseem piav txog ntau theem ntawm kev sim ua haujlwm. Ib qho ntxiv, cov rebar kuj tuaj yeem ua tiav raws li daim ntawv thov.
Kev faib tawm, xws li cov kab hlau hlau zoo tib yam rau kev txhawb nqa pob zeb thiab kub-kho cov hlau tuav rau prestressed siv zog.
