Qhov txawv ntawm I-beam HW HM Hn H-beam
HW HM HN H yog lub npe dav dav ntawm H-beam, H-beam yog welded;HWM HM HN kub dov
HW txhais tau hais tias qhov siab ntawm H-shaped steel thiab qhov dav ntawm flange yog qhov sib npaug;nws yog tsuas yog siv rau steel core kem nyob rau hauv lub reinforced qhob ncej qauv kem, kuj hu ua lub txhav steel kem;nws yog tsuas yog siv rau kem nyob rau hauv lub steel qauv
HM yog qhov sib piv ntawm H-shaped steel qhov siab rau flange dav yog kwv yees li 1.33 ~ 1.75, feem ntau hauv cov qauv steel: siv los ua steel ncej thiab ncej kab teeb nyob rau hauv thav duab qauv bearing dynamic loads;Piv txwv li: khoom siv platforms
HN yog qhov sib piv ntawm qhov siab ntawm H-shaped steel rau qhov dav ntawm flange yog ntau dua lossis sib npaug rau 2;nws yog tsuas yog siv rau kab teeb;
Kev siv ntawm I-beam yog sib npaug ntawm HN-beam;
1. Txawm hais tias I-shaped steel zoo tib yam los yog lub teeb, vim hais tias tus ntoo khaub lig-sectional loj yog kuj siab thiab nqaim, lub sij hawm ntawm inertia ntawm ob lub ntsiab tes tsho ntawm tus ntoo khaub lig-section yog heev txawv.Yog li ntawd, nws feem ntau tsuas yog siv ncaj qha rau ntawm nws lub vev xaib Bending cov tswv cuab hauv lub dav hlau los yog tsim lawv rau hauv cov tswvcuab-hom kev ntxhov siab.Nws tsis haum rau axial compression cov tswv cuab lossis cov tswv cuab uas yog perpendicular rau lub vev xaib dav hlau thiab muaj cov tswv cuab khoov, uas txwv nws cov ntawv thov ntau yam.
2. H-beams belongs rau high-efficiency thiab economical txiav profiles (lwm yam xws li txias-tsim nyias-walled steel, profiled steel daim hlau, thiab lwm yam), vim hais tias ntawm tsim nyog tus ntoo khaub lig-sectional duab, lawv muaj peev xwm ua rau cov hlau zoo dua thiab txhim kho lub peev xwm txiav.Qhov sib txawv ntawm qhov zoo li I-puab, lub flange ntawm H-shaped steel yog dav, thiab sab hauv thiab sab nrauv feem ntau yog sib npaug, uas ua rau nws yooj yim rau kev sib txuas nrog lwm cov khoom siv nrog cov qwj siab.Nws qhov loj me yog qhov tsim nyog, thiab cov qauv ua tiav, uas yooj yim rau kev tsim thiab xaiv.
3. Cov flanges ntawm H-shaped steel yog tag nrho cov tuab tuab, muaj cov dov seem, thiab tseem muaj cov seem ua ke uas muaj peb daim hlau welded.I-beams yog tag nrho cov dov seem.Vim tias cov cuab yeej siv tsis zoo, cov npoo sab hauv ntawm flange muaj txoj kab nqes ntawm 1:10.Lub dov ntawm H-zoo li tus hlau yog txawv los ntawm zoo tib yam I-shaped steel nrog tsuas yog ib txheej ntawm kab rov tav yob.Vim tias nws cov flange yog dav thiab tsis muaj txoj kab nqes (los yog txoj kab nqes me), nws yog ib qho tsim nyog yuav tsum tau ntxiv ib txheej ntsug yob rau yob tib lub sijhawm.Yog li ntawd, nws cov txheej txheem dov thiab cov khoom siv yog qhov nyuaj dua li cov rolling mills.Qhov siab tshaj plaws ntawm dov h-beam uas tuaj yeem tsim nyob rau hauv Suav teb yog 800mm, uas tuaj yeem tsuas yog welded ua ke seem.
