Los ntawm skyscrapers mus rau hla hiav txwv txuas hniav, los ntawm lub dav hlau mus rau cov chaw tsim khoom ntse, cov qauv hlau tau hloov kho lub ntsej muag ntawm niaj hnub engineering nrog nws cov kev ua tau zoo heev. Raws li lub hauv paus tseem ceeb ntawm kev tsim kho kev lag luam, steel qauv tsis tsuas yog dais qhov hnyav ntawm lub cev qhov chaw, tab sis kuj qhia txog kev txawj ntse ntawm tib neeg cov khoom siv science thiab engineering technology. Tsab ntawv xov xwm no yuav txheeb xyuas qhov tsis meej ntawm qhov "steel skeleton" los ntawm peb qhov ntev: cov yam ntxwv ntawm cov khoom siv raw, kev tsim cov txheej txheem tshiab, thiab daim ntawv thov kev nthuav dav.
1. Kev hloov pauv ntawm cov hlau: kev ua tiav ntawm cov khoom siv raw
Lub hauv paus ntawm niaj hnub steel qauv yog nyob rau hauv lub nruam innovation ntawm cov ntaub ntawv. Cov pa roj carbonLub tsev tsim(Q235 series) tseem yog thawj qhov kev xaiv rau lub cev pob txha ntawm cov nroj tsuag thiab cov vaj tsev zoo tib yam vim nws cov weldability zoo heev thiab kev lag luam; thaum qis-alloy high-strength steel (Q345/Q390) nce lub zog tawm los ntawm ntau tshaj 50% los ntawm kev ntxiv cov kab xws li vanadium thiab niobium, dhau los ua "lub zog" ntawm cov tub ntxhais tube ntawm super-high-rise vaj tse.
2. Intelligent Manufacturing Revolution: Precision Production Process
Raws li cov nthwv dej ntawm digitalization, steel qauv tsim tau tsim cov txheej txheem ntse ntse:
Kev txawj ntse txiav: Lub laser txiav tshuab carves lub contours ntawm complex Cheebtsam ntawm cov hlau phaj nrog ib tug raug ntawm 0.1 hli;
Neeg hlau vuam: Lub 6-axis neeg hlau caj npab koom tes nrog qhov pom kev pom kom ua tiav 24-teev nruam vuam tsim;
Modular pre-installation: Lub 18,000-tuj steel daim phiaj ntawm Beijing Daxing tshav dav hlau ua tiav xoom-yuam kev sib dhos ntawm kaum tawm txhiab ntawm cov khoom siv los ntawm BIM thev naus laus zis.
Kev tawg ntawm kev sib txuas thev naus laus zis yog qhov tseem ceeb tshwj xeeb:
High-strength bolt kev twb kev txuas: 10.9S-qib ntsia liaj qhov rooj preload mus txog 1550MPa, thiab 30,000 nodes ntawm Shanghai Tower tag nrho txais kev sib txhuam kev sib txuas;
3. Daim ntawv thov hla ciam teb: Hlau fais fab ntawm lub ntiaj teb mus rau qhov tob tob
Kev tsim kho engineering field:
Lub 632-meter Shanghai Ntauwd tau txais ob-txheej kab hlau rhuav phab ntsa + loj thav duab system, thiab 85,000 tons ntawm cov hlau yog siv los ua "lub nroog ntsug";
Infrastructure teb:
Lub ntsiab pej thuam ntawm Shanghai-Suzhou-Jiangyin Yangtze River Highway thiab Railway Choj txais Q500qE choj hlau, thiab ib qho kev sib tw cable bears 1,000 tons;
Cov nroj tsuag hauv av ntawm Baihetan Hydropower Station txais cov qauv hauv ob sab phlu, uas tuaj yeem tiv taus qhov kev sim ntawm 24 lab tons ntawm dej thrust.

Keeb kwm ntawmCov qauv hlaukev loj hlob yog keeb kwm ntawm kev tsim kho tshiab uas tib neeg tawm tsam cov kev txwv ntawm physics. Nyob rau hauv Suav teb, qhov chaw muaj koob meej ntawm cov tsev prefabricated tau tshaj 30%, thiab niaj hnub no thaum lub tswv yim ntawm qhov chaw elevator tau dhau los ua qhov tseeb, kev sib tsoo ntawm cov hlau thiab kev txawj ntse thaum kawg yuav tsim kom muaj zog dua, sib dua thiab ruaj khov rau yav tom ntej qhov chaw.
