Cov hlau hlau uas muaj zog muaj keeb kwm ntev, thiab nws txoj kev tsim khoom thiab kev siv hauv kev lag luam tuaj yeem taug qab rov qab mus rau xyoo 1920. Nws tau dhau los ua kev txhim kho tseem ceeb ntau xyoo, ua rau muaj ntau yam khoom nrog cov yam ntxwv sib txawv uas haum rau ntau yam kev siv. Cov no suav nrog cov hlau txias rub, cov hlau ncaj thiab tempered, cov hlau so qis, cov hlau galvanized thiab cov hlau scored. Cov khoom no thiab cov hlau prestressed strands ua los ntawm lawv tau dhau los ua cov hlau prestressed siv dav tshaj plaws uas paub thoob ntiaj teb.

12.7 hli prestressed steel hlau yog ib qho hlau hlau zoo uas tsim tshwj xeeb los ua kom tau raws li qhov yuav tsum tau ua ntawm cov pob zeb prestressed. Nws yog ua los ntawm cov hlau kub kub dov uas tau kho cua sov thiab ua haujlwm txias kom tau txais cov yam ntxwv xav tau. Cov ntsiab lus carbon ntawm hom hlau no yog 0.65% txog 0.85%, thiab cov ntsiab lus sulfur thiab phosphorus tsawg, tsawg dua 0.035%.
Lub zog tensile ntawm cov hlau hlau feem ntau yog siab tshaj 1470MPa, thiab qib zog tau maj mam hloov pauv los ntawm feem ntau 1470MPa thiab 1570MPa mus rau feem ntau 1670 ~ 1860MPa. Hauv cov nqe lus ntawm txoj kab uas hla, cov hlau hlau tau tsim los ntawm ntau dua 3 hli mus rau qhov tam sim no ntawm 5 txog 7 hli.
Los ntawm qhov kev faib tawm, 12.7 hli prestressed steel wire yog cov hlau zoo prestressed concrete steel wire. Nws yog tsim tshwj xeeb los ua kom tau raws li qhov yuav tsum tau ua ntawm prestressed concrete reinforcement, muab lub zog thiab kev ruaj khov rau cov haujlwm tsim kho siv nws.
Saib cov lus qhia tshwj xeeb, 12.7 hli prestressed steel hlau muaj cov ntsiab lus carbon ntawm 0.65% txog 0.85%, ua kom ntseeg tau tias kev ua tau zoo xav tau rau cov khoom siv muaj zog thiab ruaj khov. Nws kuj muaj cov ntsiab lus sulfur thiab phosphorus qis dua, ua kom nws cov kev ua tau zoo dua. Lub zog tensile ntawm cov hlau yog ntau dua 1470MPa, thiab lub cheeb yog nyob rau hauv ntau ntawm 5 txog 7 hli.
12.7 hli prestressed steel hlau yog siv dav hauv ntau yam kev tsim kho vim nws lub zog tensile siab thiab kev ua tau zoo heev. Nws feem ntau yog siv rau hauv cov qauv prestressed concrete los muab kev txhawb nqa thiab kev ruaj khov. Txawm hais tias siv rau hauv cov choj, cov tsev lossis lwm yam haujlwm tsim kho vaj tse, cov hlau hlau no ua kom muaj kev ywj pheej thiab kev ua haujlwm ntev ntawm cov qauv uas nws txhawb nqa. Nws qhov kev hloov pauv thiab kev ntseeg tau ua rau nws yog ib feem tseem ceeb ntawm kev tsim kho vaj tse niaj hnub.
Hauv kev xaus lus, 12.7 hli prestressed steel hlau yog cov khoom zoo uas ua tau raws li qhov yuav tsum tau ua ntawm cov pob zeb prestressed. Nws lub zog zoo dua, cov ntsiab lus sulfur thiab phosphorus tsawg, thiab ntau yam kev qhia ua rau nws zoo tagnrho rau ntau yam kev siv hauv kev tsim kho. Nrog nws keeb kwm ntev thiab kev lees paub thoob ntiaj teb, cov hlau hlau no tau dhau los ua ib feem tseem ceeb ntawm kev lag luam kev tsim kho, ua kom ntseeg tau tias muaj kev ruaj khov thiab kev ruaj khov ntawm cov qauv thoob ntiaj teb.
