H-beams nyob rau hauv European qauv yog categorized raws li lawv tus ntoo khaub lig-sectional duab, loj thiab txhua yam khoom. Nyob rau hauv cov koob no, HEA thiab HEB yog ob hom, txhua tus muaj cov ntawv thov tshwj xeeb. Hauv qab no yog cov lus piav qhia ntxaws ntawm ob tus qauv no, suav nrog lawv qhov sib txawv thiab siv tau.
HEASeries
HEA series yog ib hom H-beam steel nrog nqaim flanges uas tsim nyog rau kev tsim vaj tsev uas xav tau kev txhawb nqa siab. Hom hlau no feem ntau yog siv rau hauv cov tsev siab siab, txuas hniav, tunnels, thiab lwm yam engineering fields.Qhov tsim ntawm HEA seem yog tus cwj pwm los ntawm qhov siab ntawm seem thiab lub vev xaib nyias nyias, uas ua rau nws ua tau zoo nyob rau hauv kev tiv thaiv lub sijhawm loj bending.
Hla-section duab: Tus ntoo khaub lig-section duab ntawm HEA series nthuav qhia H-zoo li, tab sis nrog qhov dav dav dav.
Qhov ntau thiab tsawg: Cov flanges yog qhov dav tab sis cov webs nyias nyias, thiab qhov siab feem ntau yog li ntawm 100mm txog 1000mm, piv txwv li, qhov ntev ntawm HEA100 yog kwv yees li 96 × 100 × 5.0 × 8.0mm (qhov siab × dav × web thickness × flange thickness).
Meter qhov hnyav (qhov hnyav ib 'meter'): Raws li tus qauv naj npawb nce, lub 'meter' hnyav kuj nce. Piv txwv li, HEA100 muaj ib lub 'meter' hnyav ntawm kwv yees li 16.7 KG, thaum lub HEA1000 muaj qhov hnyav dua meter.
Lub zog: siab zog thiab nruj, tab sis kuj tsis tshua muaj peev xwm nqa tau piv rau HEB series.
Kev ruaj ntseg: Cov flanges nyias nyias thiab cov webs kuj tsis muaj zog ntawm kev ruaj ntseg thaum raug siab thiab khoov lub sij hawm, txawm hais tias lawv tseem tuaj yeem ua tau raws li ntau yam kev cai nyob rau hauv ib qho tsim nyog tsim ntau yam.
Torsional tsis kam: Lub torsional tsis kam yog qhov txwv thiab tsim nyog rau cov qauv uas tsis tas yuav muaj zog torsional siab.
Daim ntaub ntawv: Vim nws qhov siab seem siab thiab zoo dabtsi yog khoov lub zog, HEA seem feem ntau yog siv nyob rau hauv qhov chaw tseem ceeb, xws li nyob rau hauv lub core qauv ntawm high-sawv vaj tse.
Tus nqi tsim khoom: Cov khoom siv me me, cov txheej txheem tsim khoom yog qhov yooj yim, thiab cov kev cai rau cov khoom siv ntau lawm kuj tsawg, yog li tus nqi tsim khoom kuj tsawg.
Kev Lag Luam Nqe: Hauv kev ua lag luam, rau tib qhov ntev thiab ntau, tus nqi feem ntau qis dua HEB series, uas muaj qee qhov txiaj ntsig zoo thiab tsim nyog rau cov nqi tsim nyog.
HEBSeries
HEB series, ntawm qhov tod tes, yog qhov dav-flange H-beam, uas muaj peev xwm ua tau ntau dua piv rau HEA. Hom hlau no tshwj xeeb tshaj yog tsim rau cov tsev loj, txuas hniav, yees, thiab lwm yam kev siv uas yuav tsum tau nqa cov khoom loj.
Seem Shape: Txawm hais tias HEB kuj tseem nthuav tawm H zoo tib yam, nws muaj qhov dav dav dav dua li HEA, uas muab kev ruaj ntseg zoo dua thiab muaj peev xwm nqa tau.
Qhov ntau thiab tsawg: lub flange yog dav dua thiab lub vev xaib yog thicker, qhov siab ntau kuj yog los ntawm 100mm mus rau 1000mm, zoo li cov specification ntawm HEB100 yog hais txog 100 × 100 × 6 × 10mm, vim hais tias ntawm lub dav flange, lub cross sectional cheeb tsam thiab lub meter qhov hnyav ntawm HEB yuav loj dua li ntawm tus qauv sib xws.
Meter hnyav: Piv txwv li, lub 'meter' hnyav ntawm HEB100 yog hais txog 20.4KG, uas yog ib qho kev nce ntxiv piv rau 16.7KG ntawm HEA100; qhov sib txawv no yuav pom tseeb dua thaum tus qauv tus lej nce.
Lub zog: Vim lub flange dav thiab tuab lub web, nws muaj zog tensile ntau dua, tawm los taw tes thiab shear zog, thiab muaj peev xwm tiv taus ntau dua dabtsi yog khoov, shear thiab torque.
Stability: Thaum raug cov loads loj thiab sab nraud, nws qhia tau hais tias zoo dua stability thiab tsis tshua muaj deformation thiab instability.
Torsional kev ua tau zoo: wider flange thiab thicker web ua nws superior nyob rau hauv torsional kev ua tau zoo, thiab nws muaj peev xwm tiv taus lub torsional quab yuam uas yuav tshwm sim thaum siv cov qauv.
Daim ntaub ntawv: Vim nws cov flanges dav dua thiab qhov loj hla ntu loj, HEB seem yog qhov zoo tagnrho rau cov ntawv thov uas yuav tsum tau muaj kev txhawb nqa ntxiv thiab kev ruaj ntseg, xws li kev tsim kho ntawm cov tshuab hnyav lossis kev tsim kho cov choj loj.
Cov nqi tsim khoom: Ntau cov khoom siv raw yuav tsum tau ua, thiab cov txheej txheem tsim khoom yuav tsum muaj cov cuab yeej siv thiab cov txheej txheem ntau dua, xws li kev siab dua thiab kev tswj xyuas meej dua thaum dov, ua rau cov nqi ntau lawm.
Tus nqi lag luam: Cov nqi tsim khoom ntau dua ua rau tus nqi lag luam siab, tab sis nyob rau hauv cov haujlwm uas yuav tsum tau ua haujlwm siab, tus nqi / kev ua tau zoo yog tseem siab heev.
Kev sib piv
Thaum xaiv ntawmHehehe / Heb, qhov tseem ceeb nyob rau hauv qhov kev xav tau ntawm qhov project tshwj xeeb. Yog tias qhov project xav tau cov ntaub ntawv nrog kev khoov zoo thiab tsis cuam tshuam los ntawm qhov chaw txwv, ces HEA yuav yog qhov kev xaiv zoo dua. Hloov pauv, yog tias lub hom phiaj tseem ceeb ntawm txoj haujlwm yog los muab kev txhawb nqa muaj zog thiab ruaj khov, tshwj xeeb tshaj yog nyob rau hauv cov khoom tseem ceeb, HEB yuav tsim nyog dua.
Nws tseem ceeb heev uas yuav tsum nco ntsoov tias tej zaum yuav muaj qhov sib txawv me ntsis ntawm HEA thiab HEB profiles uas tsim los ntawm cov chaw tsim khoom sib txawv, yog li nws yog ib qho tseem ceeb uas yuav tsum tau txheeb xyuas qhov tsis sib xws kom ua raws li cov qauv tsim thaum lub sij hawm yuav khoom thiab siv cov txheej txheem. Nyob rau tib lub sijhawm, xaiv hom twg, nws yuav tsum ua kom ntseeg tau tias cov hlau xaiv tau ua raws li cov kev cai ntawm European cov qauv xws li EN 10034 thiab tau dhau los ntawm cov ntawv pov thawj zoo. Cov kev ntsuas no pab ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov qauv kawg.
