kub muag hlau bar pas nrig rebar deformed bar

Cov hlau txuashais txog cov hlau siv rau cov pob zeb reinforced thiab cov pob zeb prestressed. Nws qhov seem yog puag ncig thiab qee zaum plaub fab nrog cov ces kaum puag ncig. Xws li cov khoom siv reinforcement puag ncig, ribbed reinforcement thiab torsion reinforcement.
Cov hlau txhawb nqa rau cov pob zeb ua vaj tse yog hais txog cov hlau ncaj lossis cov hlau coiled uas siv rau kev txhawb nqa cov pob zeb ua vaj tse. Nws cov duab yog muab faib ua cov hlau puag ncig thiab cov hlau deformed. Cov xwm txheej xa khoom yog cov hlau ncaj thiab cov hlau coiled.
Cov hlau puag ncig tiaj tiaj yog cov hlau puag ncig me me thiab cov hlau puag ncig ntawm cov hlau carbon qis.Cov hlau rebar uas tau hloov pauv lawmyog cov hlau rebar nrog cov tav ntawm qhov chaw, feem ntau nrog 2 lub tav ntev thiab cov tav transverse faib sib npaug zos raws qhov ntev. Cov duab ntawm cov tav transverse yog spiral, herringbone thiab crescent. Qhia hauv millimeters ntawm txoj kab uas hla nominal. Lub txoj kab uas hla nominal ntawmcov hlau deformedyog sib npaug rau qhov txoj kab uas hla ntawm cov hlau puag ncig uas muaj qhov sib npaug. Qhov txoj kab uas hla ntawm cov hlau txhawb nqa yog 8-50 hli, thiab qhov txoj kab uas hla pom zoo yog 8, 12, 16, 20, 25, 32 thiab 40 hli. Hom hlau: 20MnSi, 20mnv, 25mnsi thiab bs20mnsi. Cov hlau txhawb nqa feem ntau dais kev ntxhov siab tensile hauv cov pob zeb ua vaj tse. Vim yog qhov kev ua ntawm cov tav, cov hlau txhawb nqa deformed muaj peev xwm sib txuas nrog cov pob zeb ua vaj tse, yog li nws tuaj yeem dais lub zog sab nraud zoo dua. Cov hlau tuav tau siv dav hauv ntau yam qauv tsev. Tshwj xeeb tshaj yog cov qauv tsev loj, hnyav, lub teeb nyias-phab ntsa thiab cov qauv tsev siab.
