Cov European txheem H-beam hom HEA thiab HEB muaj qhov sib txawv tseem ceeb hauv cov duab sib dhos, qhov loj thiab daim ntawv thov.
HUA series
HEA yog qhov kub-dov dav-flangeH-beamnyob rau hauv European tus qauv, nrog ib tug "H"-zoo li tus ntoo khaub lig-sectional duab, ob parallel ua hauj lwm lub ntsej muag (webs) thiab ob flange daim hlau. HEA hom H-beam yog tus cwj pwm los ntawm qhov nqaim flanges thiab qhov siab loj, uas ua rau nws tsim nyog rau lub sijhawm nrog lub sijhawm khoov loj, xws li txuas hniav, cov tsev siab siab, thiab lwm yam.1. Tshwj xeeb, HEA series steels feem ntau yog siv rau cov qauv uas yuav tsum tau muaj zog thiab nruj, xws li lub tsev thav duab uas ua tau zoo nyob rau hauv ob qho tib si ntsug thiab kab rov tav loads.
HEB series
Nyob rau hauv sib piv, HEB hom H-beam kuj yog ib tug kub dov ribbed wide-flange H-beam raws li European qauv, tab sis nws cov yam ntxwv txawv ntawm HEA. Qhov chaw hla ntawm HEB hom H-beam tej zaum yuav me ntsis me dua li ntawm HEA, tab sis nws cov flange dav dav dua thiab lub vev xaib yog tuab dua, uas ua rau HEB hom H-beam zoo dua compressive kev ua tau zoo thiab tsim nyog rau daim ntawv thov scenarios uas xav tau ntau dua flange stiffness2. Qhov no txhais tau hais tias nyob rau hauv qee kis, txawm tias tushla ntucheeb tsam ntawm HEB yog me dua, nws tuaj yeem muab kev txhawb nqa zoo dua vim nws qhov dav dav thiab lub vev xaib tuab.
1. Hla ntu qhov ntev thiab cov yam ntxwv geometric
• HEA series (hnyav H-beam)
▪Nov thiab nyias flanges (flanges) thiab nyias webs (nruab nrab ntsug daim hlau).
▪ Lub teeb nyhav rau ib chav tsev ntev thiab qhov chaw me me.
▪ Lub sij hawm luv luv ntawm inertia (bending resistance) thiab seem modulus, haum rau nruab nrab load scenarios.
• HEB series (tus qauv H-beam)
▪ Cov flanges dav thiab tuab dua thiab cov webs tuab dua.
▪ Cov chav tsev hnyav dua thiab qhov chaw hla ntu ntu nce ntxiv.
▪ Lub sijhawm siab dua ntawm inertia thiab seem modulus, muaj zog khoov thiab compression tsis kam, haum rau cov qauv hnyav
3. Mechanical zog thiab daim ntawv thov scenarios
HEA
▪Suitable rau lub teeb rau nruab nrab loads, xws li lub teeb cog ncej, me platforms los yog tsis-load-bearing qauv.
▪ Kev lag luam zoo, txuag cov nqi khoom siv.
HEB
▪ Siv nyob rau hauv cov xwm txheej hnyav, xws li choj lub ntsiab kab teeb, cov kab hauv tsev siab lossis cov cuab yeej siv hnyav.
▪ Cov tawv tawv thiab lub zog ntau dua, tab sis cov nqi khoom ntau dua.
4. Lwm cov European H-beam series
▪ HEM series: thicker flanges thiab webs, tsim los rau cov khoom hnyav (xws li cov khoom siv hauv tsev hnyav).
▪IPN / IPE series: Zoo ib yam li HEA / HEB, tab sis nrog kev sib txuas flange tsim (tsis muaj nqes ntawm sab hauv ntawm flange).
Cov chaw thov
Vim muaj qhov sib txawv ntawm cov yam ntxwv saum toj no, daim ntawv thov ntawm HEA thiab HEB hom H-beams hauv qhov tseeb engineering kuj tseem tsom rau ntau yam. HEA H-beam yog qhov tsim nyog rau qhov chaw uas yuav tsum tau muaj kev nruj nruj thiab lub zog siab, xws li lub hauv paus kev txhawb nqa ntawm cov tsev loj lossis cov tub ntxhais tub ntxhais ntawm cov tsev siab. HEB H-beam, vim nws qhov dav flange loj dua thiab lub vev xaib tuab, ua tau zoo tshwj xeeb thaum raug lub siab loj. Yog li ntawd, nws yog feem ntau siv nyob rau hauv lub hauv paus qauv ntawm hnyav machinery los yog industrial nroj tsuag nrog ntau dua yuav tsum tau rau bearing muaj peev xwm.
