Prestressed qhob steel hlau yog cov hlau zoo hlau ua los ntawm cov pa roj carbon steel kub-kuav los tiag hlau rods, uas yog cua sov-kho thiab txias-ua.Nws yog tsim tshwj xeeb los ua kom tau raws li qhov yuav tsum tau ua ntawm prestressed qhob reinforcement.
Lub zog tensile ntawm prestressed pob zeb steel hlau feem ntau yog siab dua 1470MPa.Sij hawm dhau mus, qib kev siv zog tau hloov pauv ntawm 1470MPa thiab 1570MPa mus rau ntau qhov ntau ntawm 1670MPa rau 1860MPa.Cov hlau txoj kab uas hla kuj tau hloov, los ntawm thawj 3 ~ 5 hli mus rau tus qauv tam sim no ntawm 5 ~ 7 hli.Cov kev qhia tshwj xeeb no ua kom muaj kev ruaj ntseg thiab kev ntseeg siab ntawm cov hlau hlau hauv kev tiv thaiv kev ntxhov siab thiab kev thauj khoom ntawm cov txheej txheem prestressed.
Cov ntsiab lus carbon ntawm hom hlau hlau no yog 0.65% mus rau 0.85%, thiab cov ntsiab lus sulfur thiab phosphorus tsawg, ob qho tib si hauv qab 0.035%.Txij li thaum nws muaj ntau lawm thiab daim ntawv thov nyob rau hauv lub 1920s, prestressed steel hlau tau ntsib ntau xyoo ntawm txoj kev loj hlob, ua rau ib tug ntau yam ntawm cov khoom tsim nyog rau ntau yam kev siv.Cov no muaj xws li txias rub hlau, straightened thiab tempered hlau, tsis tshua muaj so xaim, galvanized hlau thiab qhab nias hlau.Prestressed steel hlau thiab prestressed steel strands ua los ntawm lawv tau dhau los ua ntau hom kev siv prestressed steel hauv ntiaj teb.
Prestressed qhob hlau muaj ob peb yam tseem ceeb uas ua rau nws tsim nyog rau kev ntxiv dag zog rau cov pob zeb.Nws lub zog tensile siab thiab tsis kam rau deformation kom ntseeg tau tias nws tuaj yeem tiv taus cov khoom tseem ceeb thiab ua kom muaj kev ncaj ncees.Tsis tas li ntawd, cov khoom qis qis ntawm qee yam ntawm cov xov hlau prestressing txo qhov kev poob ntawm qhov nro thaum lub sijhawm.Qhov no pab tswj kev ruaj ntseg ntawm cov pob zeb.Ntau hom hlau, xws li galvanized thiab tau qhab nia, muab cov yam ntxwv ntxiv xws li txhim kho corrosion los yog zoo dua daim ntawv cog lus.
Prestressed qhob xov hlau tau muab faib ua ntau hom raws li lawv cov yam ntxwv thiab kev siv.Cov no suav nrog kev so qis qis serrated PC hlau, uas txhim kho kev ntxhov siab hloov pauv thiab txo cov yam ntxwv so.Lwm qhov kev faib tawm yog nyob ntawm txoj kab uas hla ntawm cov xaim, nrog rau cov kev xaiv xws li 2.64mm rau kev siv ntau dua rau cov kab uas loj dua rau cov haujlwm hnyav.
Prestressed qhob hlau yog dav siv hauv ntau yam kev tsim kho.Feem ntau yog siv rau hauv kev tsim kho cov choj, viaducts, cov tsev siab siab thiab lwm cov qauv loj uas yuav tsum tau ua kom muaj peev xwm ua tau zoo dua.Cov hlau muaj peev xwm tiv taus qhov nro thiab tiv thaiv kev ntxhov siab ua rau nws zoo tagnrho rau kev txhawb nqa cov tswv cuab.Nws kuj tseem siv rau hauv kev tsim cov khoom siv precast pob zeb, cov txheej txheem tom qab tensioned, thiab hauv av anchoring systems uas txhim khu kev qha thiab ruaj khov cov ntaub ntawv yuav tsum tau.Qhov tseem ceeb, prestressed qhob xov hlau yog qhov tseem ceeb los xyuas kom meej lub zog ntawm cov qauv thiab kev ua haujlwm ntev ntawm ntau yam kev ua vaj tse.
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.
