Nrog rau cov ntsiab lus carbon ntawm 0.65% mus rau 0.85% thiab tsis muaj leej faj thiab phosphorus cov ntsiab lus (tsawg dua 0.035%), peb cov hlau prestressed steel yog tsim los ua kom tau raws li cov qauv kev lag luam.Hom hlau no tau siv dav txij li xyoo 1920s thiab tau hloov zuj zus mus rau ntau xyoo dhau los rau hauv cov khoom siv dav dav rau ntau yam kev siv.
Tam sim no, cia peb khawb rau hauv qee qhov tech specs.Lub zog tensile ntawm peb cov hlau hlau feem ntau tshaj 1470MPa, txhawm rau ua kom tau raws li qhov kev xav tau ntawm kev lag luam, peb cov hlau hlau tau raug tsim los tsis tu ncua, thiab tam sim no lub zog tensile li ntawm 1670MPa rau 1860MPa.Peb txoj kab uas hla ntawm cov xaim kuj tau hloov pauv, los ntawm 3 mus rau 5 hli mus rau qhov chaw ruaj khov ntawm 3 mus rau 12 hli.
Ntawm peb cov khoom, peb cov khaub thuas rub pc steel hlau yog paub txog nws qhov chaw du thiab yooj yim heev.Ncaj thiab tempered hlau muaj lub zog tensile siab, ua rau nws zoo tagnrho rau cov haujlwm hnyav.Peb cov xov hluav taws xob qis qis txo qis kev ntxhov siab thiab lav kev ua haujlwm ntev.Tsis tas li ntawd, peb kuj muab galvanized steel hlau thiab qhab nia steel hlau, txhua tus muaj nws tus yam ntxwv tshwj xeeb.
Peb cov xov hlau prestressing thiab lawv cov twisted prestressing strands tau dhau los ua cov qib steel siv ntau tshaj plaws hauv cov ntawv thov prestressing thoob ntiaj teb.Nws yog ib qho tseem ceeb hauv kev tsim kho kev lag luam, ua rau muaj kev ncaj ncees thiab kev ua haujlwm ntev ntawm cov qauv ntawm txhua yam, nrog rau cov choj, vaj tse thiab kev tsheb ciav hlau.
Hauv cov ntsiab lus, peb ntau yam ntawm cov xov hlau prestressed muaj ntau yam kev xaiv kom haum rau cov kev xav tau ntawm cov haujlwm sib txawv thiab kev siv.Nrog rau lawv lub zog tshwj xeeb, kev ua haujlwm ntev thiab ntau yam, peb cov hlau hlau ua haujlwm raws li cov pob txha ntawm kev tsim kho ntau yam thoob ntiaj teb.Cia siab rau peb cov khoom los xyuas kom meej qhov kev vam meej thiab ntev ntawm koj cov pob zeb prestressed.
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.
