Dab tsi yog daim ntawv thov ntawm European standard H-section steel HEA, HEB, thiab HEM?

H series ntawm European tus qauvH ntu steelFeem ntau suav nrog ntau tus qauv xws li HEA, HEB, thiab HEM, txhua tus muaj ntau yam tshwj xeeb kom tau raws li qhov xav tau ntawm cov haujlwm engineering sib txawv. Tshwj xeeb:

HEA: Qhov no yog qhov nqaim-flange H-section steel nrog me me cross-sectional qhov ntev thiab sib dua, ua kom yooj yim rau kev thauj thiab nruab. Nws yog feem ntau siv rau hauv kab teeb thiab kab rau cov qauv tsim thiab choj engineering, tshwj xeeb tshaj yog haum rau kev tiv thaiv loj ntsug thiab kab rov tav loads. Cov qauv tshwj xeeb hauv HEA series suav nrogHEA100, HEA120, HEA140, HEA160, HEA180, HEA200, HEA220, thiab lwm yam, txhua tus muaj qhov sib txawv ntawm qhov ntev thiab qhov hnyav.

HEB: Qhov no yog qhov nruab nrab-flange H-zoo li tus hlau, nrog cov flanges dav dua piv rau HEA hom, thiab nruab nrab qhov ntev thiab qhov hnyav. Nws yog tsim rau ntau lub tsev tsim thiab choj engineering tej yaam num uas yuav tsum tau ntau dua load-bearing muaj peev xwm. Cov qauv tshwj xeeb hauv HEB series suav nrogHEB 100 HEB 120 HEB 140 HEB 160 HEB 180 HEB 200 HEB 220lwm.

HEM Hom: Qhov no yog qhov dav-flange H-shaped steel nrog flanges uas dav dua li cov hom HEB, thiab cov seem loj thiab qhov hnyav. Nws yog qhov tsim nyog rau kev tsim vaj tsev thiab choj engineering tej yaam num uas yuav tsum tau muaj peev xwm tiv taus ntau dua loads. Txawm hais tias cov qauv tshwj xeeb ntawm HEM series tsis tau hais hauv tsab xov xwm siv, nws cov yam ntxwv zoo li dav-flange H-shaped steel ua rau nws siv dav hauv kev tsim vaj tsev thiab choj engineering.
Tsis tas li ntawd, hom HEB-1 thiab HEM-1 yog cov qauv zoo dua ntawm HEB thiab HEM hom, nrog rau qhov sib txawv ntawm qhov ntev thiab qhov hnyav ntxiv los txhim kho lawv lub peev xwm thauj khoom. Lawv tsim nyog rau kev tsim vaj tsev thiab choj engineering tej yaam num uas xav tau ntau dua load-bearing muaj peev xwm.

 

Khoom siv ntawm European StandardH-Beam Steel HE Series

European Standard H-Beam Steel HE Series feem ntau siv high-strength low-alloy steel raws li cov khoom siv los xyuas kom meej kev ua tau zoo thiab lub neej ntev kev pab cuam. Cov hlau no nthuav tawm zoo heev ductility thiab toughness, muaj peev xwm ua tau raws li qhov xav tau ntawm ntau yam kev siv cov txheej txheem nyuaj. Cov ntaub ntawv tshwj xeeb suav nrog S235JR, S275JR, S355JR, thiab S355J2, thiab lwm yam. Cov ntaub ntawv no ua raws li European Standard EN 10034 thiab tau txais daim ntawv pov thawj EU CE.
