Cov hlau hlau prestressed yog cov hlau hlau zoo ua los ntawm cov hlau kub-carbon hlau. Tom qab kev kho cua sov thiab kev ua kom txias kom ua tau raws li qhov yuav tsum tau ua ntawm cov pob zeb prestressed. Cov ntsiab lus carbon ntawm cov hlau hlau no yog 0.65% txog 0.85%, thiab cov ntsiab lus sulfur thiab phosphorus yog ob qho tib si qis dua 0.035%. Cov hlau hlau prestressed tau tsim tawm hauv kev lag luam txij li xyoo 1920. Tom qab ntau xyoo ntawm kev txhim kho, ntau yam khoom tsim nyog rau ntau daim ntawv thov tau tsim tawm.
Los ntawm qhov kev pom ntawm cov lus qhia, lub zog tensile ntawm cov hlau prestressed feem ntau yog siab dua 1470MPa. Tau ntau xyoo, qib zog tau hloov pauv los ntawm feem ntau 1470MPa thiab 1570MPa mus rau feem ntau 1670 ~ 1860MPa. Lub cheeb ntawm cov hlau kuj hloov pauv, los ntawm 3 txog 5 hli mus rau 5 txog 7 hli. Cov lus qhia no ua kom ntseeg tau tias cov khoom siv uas txhawb nqa cov qauv pob zeb ua kom ruaj khov thiab ua haujlwm tau zoo.
Ib pawg ntawm cov hlau prestressed suav nrog cov hlau txias-drawn, hlau ncaj thiab tempered, hlau tsis so, hlau galvanized, thiab hlau scored. Cov variants no muaj ntau yam ntxwv kom tau raws li qhov xav tau sib txawv. Piv txwv li, cov hlau txias-drawn yog paub rau nws qhov chaw du thiab lub zog tensile siab. Cov hlau ncaj thiab tempered muab kev ywj pheej zoo heev thiab kev faib tawm kev ntxhov siab zoo dua. Cov hlau tsis so qis txo qhov poob ntawm prestress. Cov hlau galvanized yog corrosion-resistant, thaum cov hlau scored txhim kho kev nplaum rau cov pob zeb.
Cov yam ntxwv ntawm cov hlau prestressed ua rau lawv nrhiav tau ntau hauv kev tsim kho. Nws lub zog tensile siab ua kom nws muaj peev xwm tiv taus cov khoom hnyav thiab tiv taus deformation. Cov txheej txheem tsim khoom meej ua kom muaj qhov zoo thiab kev ntseeg siab. Nws muaj ntau txoj kev xaiv muaj los ua kom tau raws li qhov xav tau ntawm ib qho project tshwj xeeb. Cov hlau prestressed siv dav hauv cov choj, cov tsev, kev tsheb ciav hlau, thiab kev tsim kho txoj kev loj. Nws daim ntawv thov pab txhawb cov qauv pob zeb, ua rau lawv lub zog thiab lub peev xwm thauj khoom ntau ntxiv.
Vim nws muaj ntau yam thiab muaj cov yam ntxwv zoo heev, cov hlau prestressed tau dhau los ua ib hom hlau prestressed uas siv dav tshaj plaws hauv ntiaj teb. Tau ntau xyoo, nws cov khoom tsim tau nce ntxiv tas li kom tau raws li qhov xav tau ntawm kev lag luam kev tsim kho. Los ntawm kev ua tau raws li cov kev cai nruj rau kev txhawb nqa cov pob zeb prestressed, hom hlau no tseem ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab kev ruaj khov ntawm ntau yam kev tsim kho thoob plaws ntiaj teb.
