Hlau tseem yog qhov tseem ceeb hauv cov kab hlau rhuav phab ntsa rau siab -nce façades, ua kom ntev dua, cov ntaub ntawv sib luag, thiab txhim khu kev qha tiv thaiv cua, seismic, thermal, thiab dej loads thaum tseem tsis tau -load- bearing. Kev ua tau zoo yog tswj hwm los ntawm cov txheej txheem uas tau hais tseg es tsis yog cov qauv txheej txheem ib leeg. Kos rau qhov kev ntsuam xyuas sib piv xws li cov ntawv luam tawm hauvPhau ntawv Journal of Architectural Engineering(ASCE, 2026), uas tau tshuaj xyuas ASTM cov txheej txheem ntsuas kev tiv thaiv European, Canadian, thiab Australian txoj hauv kev rau façade systems, thiab ntawm cov khoom sib npaug ntawm cov kev taw qhia los ntawm cov chaw suav nrog PolyU CNERC cov kws tshaj lij qhia txog steel sib npaug rau cov phiaj xwm Eurocode, qhov sib txawv ntawm US thiab European lub hauv paus ua kom pom tseeb hauv ob qho tib si tsim thiab kev tsim kho.
Hauv Tebchaws Meskas, ASTM A36 / A36M carbon structural steel (tsawg kawg yield 250 MPa) yog nquag teev rau mullions, reinforcements, thiab anchors vim nws weldability thiab nqi profile. Cov txheej txheem -qib pov thawj yog nyob ntawm qhov kev sim ua pov thawj: ASTM E330 rau kev ua haujlwm nyob rau hauv cov huab cua zoo li qub-siab sib txawv (deflection thiab qhov kawg lub zog nyob rau hauv tsim cua), ASTM E331 rau dej nkag, thiab ASTM E283 rau huab cua to. Kev tsim qauv ntawm cov tswv cuab steel lawv tus kheej ua raws li AISC 360 siv qhov Tso Cai Stress Design lossis Load thiab Resistance Factor Design, koom nrog International Building Code rau qhov chaw - tshwj xeeb cua thiab seismic zones. Mock- nce kev xeem yog ib qho ntawm cov haujlwm loj.
Cov chaw ua haujlwm nyob sab Europe ntawm EN 13830:2015+A1: 2020, cov qauv khoom siv rau kab hlau rhuav- cov khoom siv phab ntsa. Nws teev cov kev cai rau huab cua- nruj, mechanical resistance, kev nyab xeeb ntawm kev siv, thiab kev ua haujlwm ntawm lub zog; Annex C qhia meej meej rau daim ntawv thov ntawm Eurocode cov cai rau curtain-cov khoom siv phab ntsa. Kev tsim qauv ntawm cov tswv cuab steel siv EN 1993-1-1 (Eurocode 3), feem ntau nrog qib S275 lossis S355 (yield 275 MPa thiab 355 MPa). Kev txwv-xeev tsim qhov txawv ntawm qhov kawg thiab kev txwv tsis pub dhau lub xeev, nrog rau kev ua cua los ntawm EN 1991-1-4 thiab kev txwv tsis pub muaj nyob ib puag ncig L / 175 txog L / 200 nyob ntawm qhov ntev. CE kos npe raws li Txoj Cai Kev Tsim Kho Cov Khoom Siv yuav tsum muaj kev kuaj xyuas thiab kev tswj hwm lub Hoobkas.
Cov ntaub ntawv xov xwm yog kwv yees ntau dua li qhov tseeb. ASTM A36 yog dav sib piv hauv lub zog rau EN S275; S355 ua kom zoo dua nrog ASTM A572 Qib 50. Txoj hauv kev hauv Teb Chaws Asmeskas leans mus rau qhov project-cov kev ntsuas empirical tshwj xeeb, thaum Eurocode 3 hais txog kev ntsuas ntsuas ntsuas los ntawm ib feem ntawm cov xwm txheej thiab txheeb xyuas los ntawm kev sim. Ob lub moj khaum xav tau kev tiv thaiv corrosion ruaj khov. Kub-dip galvanizing yog ib txwm teev rau ASTM A123 lossis EN ISO 1461; txheej txheej thickness yuav tsum txawv me ntsis los ntawm steel thickness thiab raug, thiab sib npaug ua qauv qhia feem ntau xav tau rau dual - raws li cov khoom. Thermal bridging thiab ntev -lub sij hawm durability tau txais kev pom tseeb hauv ob lub tshuab.
Kev sib tw thiab kev sib tw yuav tsum sib txawv ntawm kev ua lag luam. Hauv Tebchaws Meskas thiab Canada, qhov kev qhia tshwj xeeb feem ntau tswj hwm ASTM / AAMA cov ntaub ntawv xeem (E283, E330, E331, qee zaum ntsuas dej tsis zoo hauv qab AAMA 501) ntxiv rau AISC suav thiab, rau cov tsev siab dua, NFPA 285 hluav taws- cov pov thawj nthuav tawm. European thiab UK kev sib tw yuav tsum tau CE lossis UKCA cim rau EN 13830, Eurocode suav, thiab cov ntaub ntawv tswj hwm lub Hoobkas. Hauv Gulf (UAE, Saudi Arabia), cov tub ceev xwm xws li Dubai Lub Nroog lossis Saudi Tsev Code feem ntau lees txais cov pob khoom sib xyaw-ASTM lossis EN cov ntaub ntawv xeem ntxiv rau cov cua hauv zos- thauj khoom suav (feem ntau ASCE 7 lossis EN 1991-1-4) thiab pej xeem kev siv hluav taws xob{18} Suav cov haujlwm hauv tsev hais txog GB cov qauv thiab, rau qhov tseeb steel- profile iav kab hlau rhuav phab ntsa, cov koom haum tshwj xeeb xws li T / CECS 1482-2023, thaum xa tawm- cov neeg tsim khoom siv yuav tsum ua kom pom ASTM lossis EN sib npaug. Nruab nrab-Tsab hnub tuaj thiab sab hnub tuaj-Asian kev sib tw nce ntxiv thov cov ntaub ntawv kuaj xyuas thib peb, cov khoom siv taug qab, thiab, rau kev cuam tshuam ntawm ntug hiav txwv, ntau dua zinc txheej txheej.
Yog li ntawd, kev xaiv ua raws li peb lub tswv yim. Ua ntej, daim ntawv qhia txog kev tswj hwm kev txiav txim ntxov ntxov thiab txheeb xyuas qhov kev sim thawj zaug (ASTM series lossis EN 13830 suite) es tsis yog kev sib hloov pauv. Thib ob, xaiv cov qib steel thiab txheej txheej txheej txheem uas ua tau raws li ob qho tib si kev xav tau ntawm AISC / Eurocode 3 thiab cov kev xav tau ntev ntawm cov chav kawm raug; nruam galvanized kauj lossis daim ntawv rooj sib tham ASTM A653 lossis EN 10346, tom qab tsim thiab, qhov xav tau, batch-galvanized rau A123/ISO 1461, muab txoj hauv kev txheeb xyuas tau. Thib peb, tau txais qhov project- tshwj xeeb mock- nce lossis ntaus - cov ntaub ntawv xeem thiab tuav daim ntawv pov thawj tag nrho thiab txheej txheej - cov ntaub ntawv tuab. Dual -cov pob ua raws cai uas ua kom pom qhov sib npaug ntawm ASTM thiab EN txoj hauv kev txo kev pheej hmoo ntawm cov haujlwm thoob ntiaj teb.
Rau cov kab hlau rhuav-fab ntsa fabricators thiab cov neeg cog lus nrhiav hlau uas ua tau raws li cov kev ua tau zoo thiab cov ntaub ntawv xav tau, siab - kub zoo-dipgalvanized steel kaujthiabgalvanized steel daim ntawv formulated rau lub tsev façadesmuab cov zinc txheej zoo ib yam, qhov tseeb qhov tseeb, thiab cov ntaub ntawv zeb tsim nyog. Hu rau pab pawg kws tshaj lij ntawm sino-galvanized.com los tham txog qib, txheej txheej, thiab cov ntawv pov thawj cov pob khoom raws li ASTM, Eurocode, lossis hybrid kev sib tw specifications.
