Prestressed steel hlau yog cov khoom siv high-carbon steel hlau tsim los ntawm kev kho cua sov thiab kev ua haujlwm txias.Nws yog tsim tshwj xeeb los ua kom tau raws li qhov yuav tsum tau ua ntawm prestressed qhob reinforcement.Cov hlau hlau muaj cov ntsiab lus carbon ntawm 0.65% mus rau 0.85% thiab cov ntsiab lus sulfur thiab phosphorus tsawg dua li 0.035%, ua kom muaj zog tensile zoo thiab ua haujlwm ntev.Txij li thaum nws muaj ntau lawm thiab daim ntawv thov nyob rau hauv lub 1920s, prestressed steel hlau tau undergone kev loj hlob tseem ceeb thiab tam sim no encompasses ib tug ntau yam ntawm cov khoom tsim nyog rau kev siv sib txawv.
Prestressed steel hlau muaj lub zog zoo heev, nrog lub zog tensile yam tsawg kawg nkaus ntawm 1470MPa.Cov qib muaj zog tau hloov zuj zus mus rau ntau xyoo, hloov ntawm qhov pib 1470MPa thiab 1570MPa mus rau 1670-1860MPa tam sim no.Txoj kab uas hla ntawm cov hlau hlau kuj tau hloov, los ntawm 3-5 mm mus rau 5-7 mm.Qhov ntau yam ntawm cov kev qhia tshwj xeeb no muab kev yooj yim thiab kev xaiv rau ntau yam kev tsim kho, tso cai rau cov engineers xaiv lub zog thiab qhov loj tshaj plaws rau lawv cov ntawv thov tshwj xeeb.
Lub prestressed steel hlau ua lag luam muaj ntau yam khoom uas muaj cov yam ntxwv sib txawv kom tau raws li cov kev xav tau sib txawv.Cov no muaj xws li txias rub hlau hlau, straightened thiab tempered steel hlau, tsis tshua muaj so steel hlau, galvanized steel hlau, tau qhab nia steel hlau, thiab lwm yam. .Qhov kev sib tw no tso cai rau cov neeg siv los nrhiav qhov zoo tshaj plaws match rau lawv cov kev xav tau tshwj xeeb, ua kom muaj kev ua haujlwm siab tshaj plaws thiab ua haujlwm tau zoo.
Ib qho ntawm cov yam ntxwv tseem ceeb ntawm prestressed steel hlau yog nws lub zog tensile siab.Lub zog no, ua ke nrog kev tswj hwm nruj ntawm cov pa roj carbon, sulfur thiab phosphorus cov ntsiab lus, ua kom ntseeg tau qhov kev ua tau zoo thiab ua haujlwm ntev ntawm cov pob zeb ua kom muaj zog.Cov hlau muaj peev xwm los kho cua sov thiab txias ua haujlwm ntxiv txhim kho nws cov khoom siv kho tshuab, ua rau nws tiv taus corrosion, qaug zog thiab kev ntxhov siab.Prestressed steel hlau yog tsim los tiv thaiv kev kub ntxhov, muab kev ruaj ntseg ntev thiab lub zog rau cov qauv.
Prestressed steel hlau yog dav siv nyob rau hauv kev tsim kho kev lag luam.Nws yog tsuas yog siv nyob rau hauv prestressed pob zeb lug xws li txuas hniav, high-sawv vaj tse, tunnels, railway lem, thiab txawm nyob rau hauv lub precast qhob kev lag luam.Lub zog thiab kev ntseeg siab ntawm cov hlau hlau ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa cov qauv no, kom ntseeg tau tias lawv tiv thaiv sab nraud xws li av qeeg thiab cov khoom hnyav.Nws cov kev ua tau zoo tshaj, kev nyab xeeb thiab kav ntev piv rau cov khoom siv dag zog ua rau nws yog thawj qhov kev xaiv rau kev xav tau kev tsim kho thoob ntiaj teb.
Hauv kev xaus, prestressed steel hlau yog ntau yam khoom siv thiab txhim khu kev qha uas tau siv dav hauv kev tsim kho kev lag luam.Nrog nws cov yam ntxwv tshwj xeeb, cov khoom lag luam dav dav thiab ua raws li cov lus qhia tshwj xeeb, nws muab lub zog thiab ua haujlwm ntev uas yuav tsum tau muaj rau kev sib tw prestressed pob zeb daim ntaub ntawv.Txawm hais tias nws yog tus choj, lub tsev lossis lwm yam qauv, prestressed steel hlau muab cov engineers thiab cov neeg ua haujlwm tsim kho nrog cov kev ntseeg siab rau kev tsim cov qauv zoo thiab kav ntev.
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.
