North American structural tej yaam num raug tswj hwm los ntawm cov cai nruj kom ntseeg tau tias muaj kev nyab xeeb, ua haujlwm ntev, thiab ua haujlwm tau zoo- tsis yog- cov ntaub ntawv ua raws tuaj yeem ua rau txoj haujlwm qeeb, rov ua dua, thiab txawm tias muaj kev nyab xeeb. Rau cov kws tsim khoom thiab cov tswv haujlwm xaiv ASTM A871 Qib 65 Corten Steel, cov lus nug tseem ceeb yog: puas yog qhov siab - lub zog huab cua ua tau raws li cov cai hauv North American tsim? Cov lus teb yog yog, tab sis kev nkag siab txog cov lej twg siv thiab yuav ua li cas txheeb xyuas kev ua raws cai yog qhov tseem ceeb rau txoj haujlwm ua tiav.
Core North American Codes Pom Zoo ASTM A871 Qib 65
ASTM A871 Qib 65 tau ua tiav tag nrho nrog peb lub hauv paus kev cai uas tswj hwm North American structural tej yaam num, tag nrho raws li nws cov ASTM A871 / A871M puag tus qauv:
ASTM A871 / A871M (Base Txuj): Qhov no yog cov ntsiab lus tseem ceeb rau cov hlau nws tus kheej, txhais nws qhov 450 MPa (65 ksi) yam tsawg kawg nkaus lub zog, 550 MPa yam tsawg kawg nkaus tensile lub zog, zoo - nplej xyaum, thiab corrosion kuj (ASTM G101 Performance index Ntau dua los yog sib npaug rau 6.0). Tag nrho North American structural codes siv tus qauv no rau kev ua raws li cov khoom siv.
TIAB SA 360: Cov cai tseem ceeb rau cov qauv hlau hauv Asmeskas thiab Canada, AISC 360 qhia meej meej txog ASTM A871 Qib 65 raws li kev ua raws qib siab- lub zog steel qauv, tsim nyog rau kev thauj khoom- bearing daim ntaub ntawv xws li tubular ncej thiab industrial framing.
IBC (International Building Code): Txais siv thoob plaws hauv Teb Chaws Asmeskas thiab Canadian cov xeev, IBC hais txog ASTM cov qauv rau cov khoom siv, lees paub ASTM A871 Qib 65 ua tau raws li nws cov kev cai rau huab cua- tiv taus, siab - lub zog steel.
Cov kauj ruam tswv yim los txheeb xyuas kev ua raws (tsis muaj lus piav qhia nyuaj)
Txhawm rau kom ntseeg tau tias koj qhov phiaj xwm nyob twj ywm ua raws, ua raws li cov kauj ruam yooj yim, ua tau raws li cov kauj ruam no - tseem ceeb rau kev zam kom tsis txhob raug nqi ntau:
Thov Mill Test Report (MTR): Nug koj tus neeg muag khoom rau MTR uas lees paub cov hlau ua tau raws li ASTM A871 Qib 65 cov kev xav tau ntawm cov khoom siv thiab tshuaj, suav nrog cov khoom siv hluav taws xob, lub zog tensile, thiab corrosion resistance index.
Qhia tag nrho ASTM Kev Tsim Nyog: Hauv cov ntaub ntawv ua haujlwm, sau "ASTM A871/A871M Qib 65 Corten Steel" (tsis yog "Corten Steel" xwb) kom tsis txhob hloov cov qib uas tsis yog - ua raws.
Vuam Ua Raws Cai: Rau cov qauv welded, ua raws li AWS D1.1 (North America tus thawj welding code) thiab siv cov ntaub ntawv sib txuas (xws li AWS E7018). ASTM A871 Qib 65 yog weldable raws li ASTM A6 / A6M cov lus qhia.
Daim Ntawv Ceeb Toom Tseem Ceeb rau Cov Huab Cua Txias
Rau North American cov cheeb tsam txias, xyuas kom cov hlau ua tau raws li ASTM E23 Charpy V-Cov kev xav tau ntawm kev cuam tshuam (15 ft-lbs ntawm -}20℃F), raws li tau txib los ntawm AISC 360 rau qhov ntsuas kub qis. Qhov no tiv thaiv nkig tawg hauv lub caij ntuj no hnyav.
Nyob rau hauv luv luv, ASTM A871 Qib 65 Corten Steel yog tag nrho cov cai -ua raws rau North American structural tej yaam num thaum ua ke nrog rau kev pov thawj thiab ua raws li AISC 360, IBC, thiab ASTM cov qauv. Nws yog ib qho kev ntseeg siab, ua raws li kev xaiv rau siab -lub zog, huab cua- tiv taus cov qauv siv thoob plaws sab av loj.
