Prestressed steel hlau yog cov hlau zoo hlau uas ua los ntawm cov pa roj carbon steel kub dov hlau qws.Tom qab kev kho cua sov thiab kev ua haujlwm txias kom ua tau raws li qhov yuav tsum tau ua ntawm prestressed qhob reinforcement.Cov ntsiab lus carbon ntawm hom hlau hlau no yog 0.65% mus rau 0.85%, thiab cov ntsiab lus sulfur thiab phosphorus yog ob qho tib si hauv qab 0.035%.Prestressed steel hlau tau raug tsim tawm txij li xyoo 1920s.Tom qab ntau xyoo ntawm txoj kev loj hlob, ib tug series ntawm cov khoom tsim nyog rau ntau daim ntaub ntawv tau raug tsim.
Los ntawm cov lus qhia tshwj xeeb ntawm qhov pom, lub zog tensile ntawm prestressed steel hlau feem ntau yog siab dua 1470MPa.Tau ntau xyoo, lub zog theem tau hloov los ntawm feem ntau 1470MPa thiab 1570MPa rau feem ntau 1670 ~ 1860MPa.Txoj kab uas hla ntawm cov hlau kuj hloov, los ntawm 3 mus rau 5 hli mus rau 5 mus rau 7 hli.Cov kev qhia tshwj xeeb no ua kom muaj kev ruaj khov thiab ua haujlwm zoo ntawm cov ntaub ntawv uas txhawb nqa cov qauv pob zeb.
Ib pawg ntawm cov xaim hluav taws xob muaj xws li cov xaim txias txias, xaim ncaj thiab tempered, cov xaim qis qis, galvanized xaim, thiab cov qhab nias.Cov variants no muaj cov yam ntxwv sib txawv kom tau raws li qhov xav tau sib txawv.Piv txwv li, txias-draw steel hlau yog lub npe hu rau nws du nto thiab siab tensile zog.Ncaj thiab tempered hlau muab kev yooj yim heev thiab txhim kho kev ntxhov siab.Low-relaxation hlau minimizes poob ntawm prestress.Galvanized steel hlau yog corrosion-resistant, thaum qhab nias steel hlau txhim kho adhesion rau pob zeb.
Cov khoom ntawm prestressed steel hlau ua rau lawv nrhiav tom qab hauv kev tsim kho.Nws lub zog tensile siab ua kom nws muaj peev xwm tiv taus cov khoom hnyav thiab tiv thaiv deformation.Precise manufacturing processes kom zoo ib yam thiab kev ntseeg tau.Nws muaj ntau yam kev xaiv muaj kom haum raws li qhov yuav tsum tau muaj ntawm ib qhov project tshwj xeeb.Prestressed steel hlau yog dav siv nyob rau hauv choj, vaj tse, railways, thiab kev loj kev tsim kho.Nws daim ntawv thov pab ntxiv dag zog rau cov vaj tse pob zeb, ua kom lawv lub zog thiab muaj peev xwm thauj khoom.
Vim nws txoj kev ua tau zoo thiab cov khoom zoo tshaj plaws, prestressed steel hlau tau dhau los ua ib qho ntawm feem ntau siv prestressed steel hom hauv ntiaj teb.Nyob rau hauv xyoo tas los, nws cov khoom tsim tau nce ntxiv kom tau raws li qhov xav tau ntawm kev tsim kho kev lag luam.Los ntawm kev ua kom tau raws li qhov yuav tsum tau ua nruj me ntsis rau kev ua vaj tse prestressed, hom steel hlau txuas ntxiv ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab ua haujlwm ntev ntawm ntau yam kev tsim kho thoob ntiaj teb.
Daim ntawv thov
Raws li Tuam Tshoj hlau cov ntaub ntawv kev lag luam ua lag luam, lub teb chaws steel kev lag luam thiab logistics "Pua pua zoo kev lag luam", Tuam Tshoj steel kev lag luam lag luam, "Top 100 private tuam txhab nyob rau hauv Shanghai". ) siv lub "Integrity, Practicality, Innovation, Win-Win" raws li nws txoj kev lag luam ib txwm ua, ib txwm ua siab ntev tso cov neeg siv khoom xav tau thawj qhov chaw.
