Txuas hniav yog ib qho tseem ceeb invention nyob rau hauv tib neeg keeb kwm. Los ntawm lub sijhawm qub thaum tib neeg siv cov ntoo thiab cov pob zeb sib tsoo los hla kev hla dej thiab cov kwj deg, mus rau kev siv cov choj koov thiab cov txuas txuas txuas txuas txuas, qhov kev hloov pauv tau zoo kawg li. Kev qhib tsis ntev los no ntawm Hong Kong-Zhuhai-Macao Choj yog qhov tseem ceeb hauv keeb kwm ntawm cov choj. Hauv kev tsim choj niaj hnub no, ntxiv rau kev siv cov pob zeb ua vaj tse, cov khoom siv hlau, tshwj xeeb yog aluminium alloys, tau dhau los ua qhov kev xaiv tseem ceeb vim lawv ntau yam zoo.

Xyoo 1933, lub ntiaj teb thawj aluminium alloy choj lawj tau siv rau ntawm tus choj hla tus dej hauv Pittsburgh hauv Tebchaws Meskas. Ntau tshaj li kaum xyoo tom qab, xyoo 1949, Canada ua tiav ib qho txhuas txhuas arch choj hla Saguenay River hauv Quebec, nrog ib qho kev ncua mus txog 88.4 meters. Tus choj no yog lub ntiaj teb thawj tus qauv txhuas txhuas. Tus choj muaj piers kwv yees li 15 meters siab thiab ob txoj kab rau tsheb tsheb. Nws siv 2014-T6 aluminium alloy thiab muaj tag nrho qhov hnyav ntawm 163 tons. Piv nrog rau txoj kev npaj ua ntej steel choj, nws txo qhov hnyav li ntawm 56%.

Txij thaum ntawd los, cov qauv ntawm aluminium alloy structural txuas hniav tau unstoppable. Nyob nruab nrab ntawm 1949 thiab 1985, lub tebchaws United Kingdom tau tsim muaj kwv yees li 35 aluminium alloy structural choj, thaum lub teb chaws Yelemees ua ib ncig ntawm 20 xws li cov choj ntawm 1950 thiab 1970. Kev tsim kho ntawm ntau tus choj muab kev paub zoo rau yav tom ntej aluminium alloy choj builders.

Piv nrog rau cov hlau, cov ntaub ntawv aluminium alloy muaj qhov ntom ntom, ua rau lawv sib dua, tsuas yog 34% ntawm qhov hnyav ntawm cov hlau rau tib lub ntim. Txawm li cas los xij, lawv muaj lub zog zoo ib yam li cov hlau. Tsis tas li ntawd, aluminium alloys pom zoo elasticity thiab corrosion kuj thaum muaj nqi kho cov qauv qis. Yog li ntawd, lawv tau pom ntau daim ntawv thov hauv kev tsim choj niaj hnub.

Tuam Tshoj tau ua qhov tseem ceeb hauv kev tsim choj thiab. Zhaozhou Choj, sawv rau ntau tshaj 1500 xyoo, yog ib qho ntawm cov kev ua tiav ntawm kev tsim choj hauv Suav teb thaum ub. Nyob rau lub sijhawm niaj hnub no, nrog kev pab los ntawm yav dhau los Soviet Union, Tuam Tshoj kuj tau tsim ntau lub choj hlau, suav nrog tus choj Yangtze River hauv Nanjing thiab Wuhan, nrog rau Pearl River Choj hauv Guangzhou. Txawm li cas los xij, daim ntawv thov ntawm aluminium alloy txuas hniav hauv Suav teb zoo li txwv. Thawj tus choj aluminium alloy structural hauv Suav teb yog tus neeg taug kev choj ntawm Qingchun Road hauv Hangzhou, ua rau xyoo 2007. Tus choj no tau tsim thiab ntsia los ntawm German choj engineers, thiab tag nrho cov ntaub ntawv tau los ntawm lub teb chaws Yelemees. Nyob rau hauv tib lub xyoo, tus neeg taug kev choj nyob rau hauv Xujiahui, Shanghai, tag nrho tsim thiab manufactured domestically siv txhuas alloy lug. Nws feem ntau siv 6061-T6 aluminium alloy thiab, txawm tias nws qhov hnyav 15-tuj, tuaj yeem txhawb nqa 50 tons.

Nyob rau hauv lub neej yav tom ntej, aluminium alloy txuas hniav muaj kev loj hlob zeem muag nyob rau hauv Suav teb rau ntau yam:

1 Tuam Tshoj txoj kev tsheb ciav hlau ceev ceev tau nce zuj zus, tshwj xeeb tshaj yog nyob rau hauv thaj chaw nyuaj ntawm thaj tsam sab hnub poob nrog ntau lub hav thiab dej ntws. Aluminium alloy txuas hniav, vim lawv txoj kev yooj yim ntawm kev thauj mus los thiab cov khoom sib zog, yuav tsum muaj kev lag luam tseem ceeb.

2 Cov khoom siv hlau tsis tshua muaj xeb thiab muaj kev ua haujlwm tsis zoo hauv qhov kub thiab txias. Corrosion ntawm steel ho cuam tshuam rau kev ruaj ntseg choj, ua rau cov nqi kho ntau dua thiab muaj kev nyab xeeb. Nyob rau hauv sib piv, aluminium alloy cov ntaub ntawv muaj zog corrosion kuj thiab ua tau zoo nyob rau hauv qis kub, ua rau lawv haum rau ntau yam kev nyab xeeb tej yam kev mob thiab xyuas kom meej lub sij hawm ntev. Txawm hais tias aluminium alloy txuas hniav tej zaum yuav muaj cov nqi pib siv ntau dua, lawv cov nqi kho mob tsawg tuaj yeem pab txo tus nqi sib txawv ntawm lub sijhawm.

3 Kev tshawb fawb ntawm aluminium choj vaj huam sib luag, ob qho tib si hauv tsev thiab txawv teb chaws, tau tsim zoo, thiab cov ntaub ntawv no tau siv dav. Kev nce qib hauv kev tshawb fawb cov ntaub ntawv muab kev ruaj ntseg rau kev tsim cov hlau tshiab uas ua tau raws li cov kev xav tau sib txawv. Tuam Tshoj aluminium manufacturers, suav nrog kev lag luam loj xws li Liaoning Zhongwang, tau maj mam hloov lawv lub hom phiaj rau kev lag luam aluminium profiles, nteg lub hauv paus rau aluminium alloy choj kev tsim kho.

4 Kev tsim kho sai hauv nroog subway hauv nroog loj hauv Suav teb ua kom nruj nruj rau cov qauv tsim los ntawm cov av saum toj no. Vim lawv qhov hnyav hnyav zoo, nws yog qhov pom tau tias ntau dua aluminium alloy neeg taug kev thiab cov choj loj yuav raug tsim thiab siv yav tom ntej.
