Vim li cas thiaj xaiv Kub Finished Hollow Sections
- Ntau yam khoom siv kho tshuab: Vim hais tias cov seem tau ua tiav ntawm qhov kub thiab txias, cov ces kaum - uas tau dhau los ua qhov txias tshaj plaws deformation hauv qhov txias - ua ntu - recrystallize thiab xaus nrog cov khoom ze dua rau lub ntsej muag tiaj tus, muab cov kev xav tau ntau dua ntawm cov qauv hauv qab load.
- Zoo dua toughness ntawm qis kub: Qib nrog "H" toughness suffix (piv txwv li, S355J2H) feem ntau tau teev tseg rau cov qauv raug rau qhov kub thiab txias ambient, seismic loading, los yog dynamic / qaug zog loading, qhov zoo sib xws toughness - nrog rau ntawm cov ces kaum - yog ib qho tseem ceeb.
- Tsis muaj qhov txias txias - ua rau muaj kev ntxhov siab: Cov txheej txheem kub ua kom tshem tawm cov kev ntxhov siab sab hauv los ntawm kev ua haujlwm, uas tuaj yeem yog ib qho kev xav tau tshwj xeeb rau cov qauv rhiab rau kev ntxhov siab los yog cov ntaub ntawv tom ntej (hnyav vuam, ntxiv kev tsim).
- Tsim kev taw qhia tsim: Cov qauv tsim qauv xws li Eurocode 3 (EN 1993-1-1 thiab EN 1993-1-8) suav nrog cov kev taw qhia tshwj xeeb thiab buckling curves tsim nrog kub tiav hollow seem hauv siab, simplifying tsim pov thawj rau cov qauv engineers.
- Kev sib npaug sib npaug - mus rau -square forming zoo: Producing SHS/RHS from a hot finished circular hollow section (rather than directly from strip) tends to give more consistent wall thickness distribution around the section, particularly at the corners.
Kub Tiav (EN 10210) vs Cold-Formed (EN 10219) Hollow Sections
| Qhov xwm txheej | Kub tiav (TS EN 10210) | Txias-Formed (TS EN 10219) |
|---|---|---|
| Ua kub | Elevated (kub) | Ambient (txias) |
| Corner yield zog | Kaw rau tiaj tus- tus nqi ntsej muag | Siab dua ( lim-hardened) |
| Rooj toughness | Feem ntau zoo dua | Yuav txo tau vim kev ua haujlwm txias |
| Residual stress | Relieved thaum kub xov | Qhia tshwj tsis yog tias muaj kev ntxhov siab sib cais -relieved |
| Dimensional kam rau ua | Txheem EN 10210-2 kam rau ua | Feem ntau nruj, raws li EN 10219-2 |
| Cov nqi tsev ib txwm | Siab dua | qis |
| Cov ntaub ntawv siv ntau | Seismic qauv, dynamic / qaug zog loading, qis- kev pab cuam kub, offshore qauv | Kev tsim kho dav dav, cov qauv tsim qauv, feem ntau cov tsev lag luam |
| Tsim cov cai qhia | Extensive (Eurocode 3, zoo-tsim cov ntaub ntawv buckling) | Kev nthuav dav, nrog rau txias - tsim cov kev cai txhim kho lub zog muaj |
Tsis yog txhua tus qauv yog "zoo dua" - EN 10210 feem ntau tau teev tseg qhov twg qhov tawv nqaij, kev ua haujlwm qaug zog, lossis qhov seem - kev ntxhov siab yog qhov tseem ceeb, thaum EN 10219 yog qhov kev lag luam ntau dua rau cov qauv siv cov qauv zoo li qub uas nws nruj dua {4} qhov tsis zoo ntawm qhov tsis zoo.
Kev Qhia Txog Kev Yuav Khoom: Yuav Ua Li Cas Xaiv Kub Tiav Square thiab Rectangular Hollow Sections
- Paub meej tias koj tus qauv tsim code yuav tsum tau kub tiav cov seem.Tshawb xyuas seb koj qhov project qhov kev suav ua qauv, seismic tsim qeb, lossis kev tsim qauv qaug zog tshwj xeeb hu rau EN 10210 cov khoom siv tsis yog EN 10219 - qhov no feem ntau tau teev nyob rau hauv qhov project specification lossis los ntawm cov txheej txheem engineers ntawm cov ntaub ntawv.
- Xaiv cov qib toughness kom raug rau koj qhov kev pabcuam kub.Cov qib "H" cov lus kawg (JRH, J0H, J2H, K2H, NH, NLH) txhua qhov sib txawv ntawm Charpy cuam tshuam qhov ntsuas kub thiab lub zog xav tau - lees paub qhov ntsuas qhov ntsuas qhov tsawg kawg nkaus rau koj cov qauv thiab phim cov qib raws li.
- Txheeb xyuas qhov loj me thiab thickness ua ke ua ntej ua tiav tsim.Tsis yog txhua phab ntsa tuab yog muaj nyob rau hauv txhua ntu loj los ntawm txhua lub zeb - paub meej tias qhov tseeb zeb tsim muaj peev xwm tiv thaiv koj cov qauv kos duab ua ntej tsim tiav, kom tsis txhob muaj kev hloov pauv lig.
FAQ
Q: Qhov txawv ntawm qhov kub tiav thiab txias - ua hollow seem yog dab tsi?
A: Cov ntu kub tiav (EN 10210) yog tsim lossis ua tiav ntawm qhov kub siab, uas txo cov kev ntxhov siab thiab muab cov khoom sib xws ntau dua nyob ib ncig ntawm ntu, suav nrog cov ces kaum. Txias- cov seem tsim (EN 10219) yog tsim los ntawm qhov kub thiab txias, uas ua rau lub kaum sab xis siab dua los ntawm kev ua kom tawv tawv, tab sis feem ntau qis dua kaum sab xis thiab qee qhov kev ntxhov siab seem.
Q: Thaum twg kuv yuav tsum qhia EN 10210 es tsis txhob EN 10219?
A: EN 10210 feem ntau tau teev tseg rau cov qauv uas yuav tsum muaj seismic tsim, dynamic los yog qaug zog loading, tsis tshua muaj kev pab cuam kub, los yog nyob rau hauv lub residual stress rhiab heev rau tom qab fabrication. Rau cov qauv zoo li qub uas tsis muaj cov kev cai no, EN 10219 feem ntau raug nqi ntau dua - zoo.
Q: Dab tsi ua rau cov ntawv toughness (JR, J0, J2, K2) txhais tau li cas hauv qib steel?
A: Cov lus txuas ntxiv no qhia qhov tsawg kawg nkaus Charpy V-qhov cuam tshuam rau lub zog thiab qhov ntsuas kub uas lub zog yuav tsum ua tiav - piv txwv li, J2 feem ntau xav tau 27J qhov cuam tshuam tsawg kawg nkaus ntawm -20℃. Cov qib toughness siab dua (K2, NL) tau teev tseg rau qhov kev pab cuam qis dua lossis cov qauv tsim nyog.
Q: Qhov kub tiav hollow seem puas tuaj yeem kub -dip galvanized?
A: Yog lawm - SHS / RHS tuaj yeem kub tau-dip galvanized tom qab ntau lawm, nyob rau hauv lub zeb los yog los ntawm ib tug nyias galvanizer, ua raws li cov qauv kev coj ua xws li ASTM A123 los yog ISO 1461, muab qhov tso pa tawm / tso dej qhov muaj nyob rau hauv cov fabrication tsim qhov yuav tsum tau.
