Cov qauv thiab cov qauv ntawm H-beams nyob rau hauv ntau lub teb chaws

H-beam yog ib hom hlau ntev nrog H-shaped cross-section, uas yog lub npe vim nws cov qauv zoo ib yam li cov ntawv Askiv "H". Nws muaj lub zog siab thiab zoo mechanical zog, thiab yog dav siv nyob rau hauv kev tsim kho, choj, machinery manufacturing thiab lwm yam teb.

Suav National Standard (GB)

H-beams nyob rau hauv Suav teb yog tsim thiab categorized raws li Kub Rolled H-beams thiab Sectional T-beams (GB/T 11263-2017). Nyob ntawm qhov dav ntawm flange, nws tuaj yeem muab faib ua dav-flange H-beam (HW), nruab nrab-flange H-beam (HM) thiab nqaim-flange H-beam (HN). Piv txwv li, HW100 × 100 sawv cev rau dav flange H-beam nrog flange dav ntawm 100mm thiab qhov siab ntawm 100mm; HM200 × 150 sawv cev rau nruab nrab flange H-beam nrog flange dav ntawm 200mm thiab qhov siab ntawm 150mm. Tsis tas li ntawd, muaj qhov txias-tsim nyias-walled steel thiab lwm yam tshwj xeeb ntawm H-beams.

European Standards (EN)

H-beams nyob rau hauv cov teb chaws Europe ua raws li ib tug series ntawm European qauv, xws li EN 10034 thiab EN 10025, uas qhia txog qhov ntev specifications, cov khoom yuav tsum tau, mechanical zog, nto zoo thiab soj ntsuam cov cai rau H-beams. Cov European qauv H-beams xws li HEA, HEB thiab HEM series; HEA series feem ntau yog siv los tiv thaiv axial thiab ntsug, xws li hauv cov tsev siab siab; HEB series yog tsim rau cov qauv me me rau nruab nrab; thiab HEM series yog haum rau cov ntawv thov uas yuav tsum muaj qhov hnyav dua tsim vim nws qhov siab me thiab qhov hnyav. Txhua series muaj nyob rau hauv ntau yam sib txawv ntau thiab tsawg.
HEA Series: HEA100, HEA120, HEA140, HEA160, HEA180, HEA200, thiab lwm yam.
HEB Series: HEB100, HEB120, HEB140, HEB160, HEB180, HEB200, thiab lwm yam.
HEM Series: HEM100, HEM120, HEM140, HEM160, HEM180, HEM200, thiab lwm yam.

American Standard H nqaj(ASTM / AISC)

American Society for Testing and Materials (ASTM) tau tsim cov qauv qhia ntxaws rau H-beams, xws li ASTM A6 / A6M. American Standard H-beam qauv feem ntau yog hais nyob rau hauv Wx los yog WXxxy hom, piv txwv li, W8 x 24, qhov "8" yog hais txog lub flange dav nyob rau hauv nti thiab "24" qhia txog qhov hnyav ib ko taw ntawm qhov ntev (phaus). Tsis tas li ntawd, muaj W8 x 18, W10 x 33, W12 x 50, thiab lwm yam. Common zog qib areASTM A36,a572 ,ua.

British Standard (BS)

H-beams raws li British Standard ua raws li cov lus qhia xws li BS 4-1: 2005 + A2: 2013. Cov hom muaj xws li HEA, HEB, HEM, HN thiab ntau lwm yam, nrog rau HN series muab tshwj xeeb rau kev muaj peev xwm tiv taus kab rov tav thiab ntsug. Txhua tus qauv naj npawb yog ua raws li tus lej los qhia txog qhov loj me, piv txwv li HN200 x 100 qhia tus qauv nrog qhov siab thiab dav.

Japanese Industrial Standard (JIS)

Japanese Industrial Standard (JIS) rau H-beams feem ntau yog hais txog JIS G 3192 tus qauv, uas muaj ntau qib xws liSIB 400, SM490, thiab lwm yam. SS400 yog cov qauv hlau dav dav haum rau kev tsim kho kev ua haujlwm, thaum SM490 muab lub zog tensile ntau dua thiab tsim nyog rau kev siv hnyav. Hom tau nthuav tawm zoo ib yam li hauv Suav teb, xws li H200 × 200, H300 × 300, thiab lwm yam. Qhov ntev xws li qhov siab thiab flange dav yog qhia.

German Industrial Standards (DIN)

Kev tsim cov H-beams hauv lub teb chaws Yelemees yog raws li cov qauv xws li DIN 1025, piv txwv li IPBL series. Cov qauv no ua kom muaj qhov zoo thiab sib xws ntawm cov khoom thiab tsim nyog rau ntau hom kev lag luam.

Australia
Txheem: AS / NZS 1594 thiab lwm yam.
Qauv: 100UC14.8, 150UB14, 150UB18, 150UC23.4, thiab lwm yam.

Los txiav txim siab, txawm hais tias cov qauv thiab hom H-beams txawv ntawm lub teb chaws mus rau lub teb chaws thiab cheeb tsam mus rau ib cheeb tsam, lawv qhia lub hom phiaj ntawm kev ua kom cov khoom zoo thiab ua tau raws li ntau haiv neeg engineering xav tau. Hauv kev xyaum, thaum xaiv txoj cai H-beam, nws yog ib qho tsim nyog yuav tsum tau xav txog cov kev cai tshwj xeeb ntawm qhov project, ib puag ncig thiab kev txwv nyiaj txiag, nrog rau kev ua raws li cov cai hauv zos thiab cov qauv. Kev nyab xeeb, ruaj khov thiab kev lag luam ntawm lub tsev tuaj yeem txhim kho tau zoo los ntawm kev xaiv thiab siv H-beams.
