Prestressed steel hlau yog ntau yam thiab tseem ceeb hauv kev tsim kho kev lag luam.Ua los ntawm cov khoom siv high-carbon steel kub dov hlau rods uas tau kho cua sov thiab ua haujlwm txias, cov xov hlau no tshwj xeeb tsim los ua kom tau raws li qhov xav tau ntawm cov pob zeb ua kom muaj zog.Cov hlau hlau muaj cov ntsiab lus carbon ntawm 0.65% mus rau 0.85%, sulfur thiab phosphorus cov ntsiab lus tsawg dua 0.035%, thiab muaj lub zog zoo thiab ua haujlwm ntev.
Prestressed steel hlau tau ua tiav zoo txij li nws cov khoom tsim thiab kev siv hauv xyoo 1920s.Niaj hnub no, ntau yam khoom tsim nyog rau kev siv sib txawv thiab nrog cov yam ntxwv sib txawv tau tsim.Cov no suav nrog cov xaim xaim txias, cov xaim ncaj nraim, cov xaim qis qis, galvanized xaim thiab cov qhab nias hlau.Cov khoom no, ua ke nrog prestressed steel strands, tau dhau los ua ntau hom prestressed steel ntau yam hauv ntiaj teb.
Raws li kev faib tawm mus, qis slack serrated PC hlau yog ib qho kev xaiv nrov.Nws lub zog tensile zoo heev ua rau nws zoo tagnrho rau kev siv kev ntxhov siab.Tsis tas li ntawd, lub thickness ntawm cov hlau hlau yog 2.64 hli, ua rau nws haum rau ntau yam kev tsim kho.Tsis tas li ntawd, cov hlau nplaum prestressed no ua raws li cov qauv teev tseg hauv 1084 SAEJ403, ua kom nws zoo thiab kev ntseeg tau.
Ib qho ntawm cov yam ntxwv tseem ceeb tshaj plaws ntawm prestressed steel hlau yog nws lub zog tensile tshwj xeeb.Feem ntau, lub zog tensile ntawm hom steel hlau no siab tshaj 1470MPa, maj mam hloov mus rau lub ntsiab lub zog ntawm 1670 ~ 1860MPa.Ntxiv mus, txoj kab uas hla ntawm cov hlau kuj tau hloov zuj zus mus rau lub sijhawm, los ntawm 3 mus rau 5 hli mus rau qhov tam sim no ntawm 5 mus rau 7 hli.Qhov no muaj zog thiab loj txoj kab uas hla ua rau cov hlau prestressed heev elastic thiab muaj peev xwm tiv taus cov khoom loj.
Vim nws cov khoom zoo heev, prestressed steel hlau yog dav siv nyob rau hauv ntau yam kev tsim kho.Nws yog feem ntau siv los ntxiv dag zog rau cov qauv xws li txuas hniav, cov tsev thiab kev tsheb ciav hlau los txhim kho lawv cov peev xwm thauj khoom thiab tag nrho cov qauv kev ncaj ncees.Cov kev lag luam thiab kev tsim kho vaj tse vam khom rau cov hlau hlau prestressed kom ntseeg tau tias lub neej ntev thiab kev nyab xeeb ntawm lawv cov haujlwm.
Nyob rau hauv cov ntsiab lus, txoj kev loj hlob ntawm prestressed steel hlau revolutionized kev tsim kho kev lag luam.Kev sib xyaw ua ke ntawm cov khoom siv high-carbon steel thiab cov txheej txheem machining siab heev ua rau muaj ntau yam khoom tsim nyog rau ntau yam kev siv.Nrog rau ntau yam kev faib tawm thiab kev xaiv loj, nrog rau lub zog tensile zoo heev thiab kev siv ntau yam, steel hlau prestressed tseem yog ib qho tseem ceeb hauv kev tsim kho niaj hnub no.
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.
