Weathering steel (Corten steel) kab hlau rhuav phab ntsa yog ib qho tshiab thiab siab - tus nqi xaiv rau siab - sawv tsev facade tsim, sib xyawarchitectural durability, tshwj xeeb aesthetics, thiab ib puag ncig adaptabilitythaum xav tau cov kev daws teeb meem rau siab -nce- cov kev sib tw tshwj xeeb. Hauv qab no yog cov ncauj lus kom ntxaws txog lawv daim ntawv thov kev ua tau zoo, cov txiaj ntsig tseem ceeb, kev txiav txim siab tsim qauv tseem ceeb, thiab kev ntsuas kev siv:
Cov khaub ncaws xim liab -xim av patina ntawm weathering steel tsim ib qho txawv retro-kev lag luam lossis ntuj tsim qauv, tsim kom pom qhov sib txawv zoo nrog iav, aluminium alloy, thiab pob zeb facades. Rau siab -cov tuam tsev lag luam nce siab, kev coj noj coj ua, lossis thaj chaw pej thuam, cov xim xeb tshwj xeeb no tuaj yeem txhim kho kev paub txog vaj tsev thiab cov duab hom, zam lub monotonous "glass box" zoo li cov tsoos siab - nce.
Weathering steel qhov ntom tiv thaiv xeb txheej tau zoo cais cov huab cua, noo noo, thiab cov pa phem hauv nroog (xws li, kua qaub nag, cov plua plav), nrog rau kev pab cuam lub neej.20-30 xyoo(los yog ntev dua nrog kev saib xyuas kom zoo) nyob rau hauv siab -nce toj ib puag ncig. Tsis zoo li cov pa roj carbon zoo tib yam, nws tsis tas yuav tsum tau pleev xim ntau zaus lossis tshem tawm xeb, txo qhov ntev - cov nqi kho façade (tseem ceeb rau siab - nce qhov kev saib xyuas sab nrauv yog kim thiab pheej hmoo).
High-lub zog huab cua steel (piv txwv li, Corten B qib) muaj lub zog tensile zoo thiab toughness, sib piv cov load-cov kabmob thiab cua- kev tiv thaiv siab ntawm - nce kab hlau rhuav phab ntsa. Nws tuaj yeem ua tiav rau hauv cov ntaub thaiv phab ntsa vaj huam sib luag, uas ua ke nrog lub tsev lub ntsiab qauv kom tiv taus cua txias (feem ntau nyob rau hauv siab - qhov siab ntawm qhov siab - nce) thiab seismic rog tsis muaj deformation lossis detachment.
Kev tsim ntawm huab cua steel txheej xeb yog txheej txheem oxidation ntuj, tshem tawm qhov xav tau rau cov tshuaj lom neeg tiv thaiv - xeb xim lossis txheej txheej uas tuaj yeem ua rau cov khoom tsis zoo. Piv rau aluminium alloy (siab zog noj hauv smelting) los yog iav (high carbon footprint nyob rau hauv ntau lawm), weathering steel muaj ib tug qis lifecycle ib puag ncig, ua raws li cov qauv tsev ntsuab (xws li, LEED, BREEAM).
Nyob rau hauv thawj theem rusting (thawj 1-3 lub hlis), weathering steel tej zaum yuav tsim cov dej xeb, uas yuav stain iav los yog txhuas cov khoom ntawm lub siab -nce facade. Cov kev daws teeb meem suav nrog:
Ua ntej- xeb thiab sealing: Conduct factory pre-rusting to form a stable patina, then spray a transparent UV-resistant glaze to lock the rust layer and prevent rust water seepage.
Unitized vaj huam sib luag tso dej: Tsim cov grooves thiab cov dej zais - khaws cov tais ntawm cov kab hlau rhuav phab ntsa kom ncaj qha cov dej seem ntawm lub tsev, kom tsis txhob hla - cov khoom sib kis ntawm cov ntaub ntawv uas nyob ib sab.
High-cov tsev nce siab ntsib cua siab dua ntawm cov plag tsev siab dua (cua nrawm nrog qhov siab). Kev ntsuas tsim muaj xws li:
Thickness optimization: Siv 6–12mm nruab nrab-thick weathering steel daim hlau rau kab hlau rhuav phab ntsa panels (reinforced nrog sab hauv tav rau loj- cheeb tsam panels) kom rigidity tiv thaiv cua loads.
Kev sib txuas ruaj ntseg: Txais cov stainless hlau zais cov txuas los kho cov vaj huam sib luag rau cov qauv tseem ceeb, nrog rau kev tiv thaiv - loosening fasteners los tiv thaiv vaj huam sib luag tawm hauv qab cua los yog kev co.
High-nce facades raug rau hnub tseem ceeb- hmo ntuj qhov sib txawv thiab hnub ci hluav taws xob, ua rau thermal expansion/contraction ntawm steel panels. Mitigation Strategies:
Expansion sib koom tsim: Teem 5-8mm expansion pob qij txha ntawm cov panels uas nyob ib sab kom haum rau thermal deformation thiab tsis txhob tawg los yog warping.
Thermal rwb thaiv tsev txheej kev koom ua ke: Ntxiv cov hluav taws kub nyhiab thiab thermal rwb thaiv tsev tub ntxhais (xws li, pob zeb ntaub plaub, polyurethane) nruab nrab ntawm cov huab cua steel vaj huam sib luag thiab lub tsev phab ntsa sab hauv kom txo tau cov cua kub hloov thiab txo qhov kub thiab txias - ua rau muaj kev ntxhov siab ntawm cov hlau.
High -nce facade tu yog nyuaj thiab kim. Kom yooj yim tu:
Modular vaj huam sib luag tsim: Siv cov detachable unitized panels uas tuaj yeem hloov tau ib tus zuj zus los yog khaws cia ntawm lub tsev tu tsev (BMUs) yam tsis muaj kev cuam tshuam rau tag nrho lub façade.
Tsawg-kev kho qhov chaw tu: Lub pob tshab tiv thaiv glaze txo qhov xav tau kev tu ntau zaus; Tsuas yog qee zaus siab - qhov siab tshem tawm plua plav tawm (ntawm BMUs) yog yuav tsum tau ua kom lub patina qhov sib xws.
