Qhov sib txawv thiab daim ntawv thov ntawm H-beam thiab I-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 nrog khoov perpendicular rau lub vev xaib dav hlau, uas txwv nws cov ntawv thov ntau yam. tus
2. H-beams yog high-efficiency thiab economical tej profiles (lwm yam xws li txias-tsim nyias-walled steels, profiled steel phaj, thiab lwm yam). Vim yog qhov tsim nyog cov duab sib dhos, lawv tuaj yeem ua rau cov hlau zoo dua thiab txhim kho lub peev xwm txiav. Sib txawv ntawm cov hlau zoo li I-shaped, lub flange ntawm H-shaped steel yog dav, thiab sab hauv thiab sab nrauv feem ntau yog sib npaug, uas tuaj yeem pab txhawb kev sib txuas nrog lwm cov khoom siv nrog lub zog siab bolts. Nws qhov loj me yog qhov tsim nyog, thiab cov qauv ua tiav, uas yooj yim rau kev tsim thiab xaiv (tshwj tsis yog rau I-shaped steel rau crane beams).
3. Cov flanges ntawm H-zoo li tus hlau yog tag nrho cov tuab tuab, thiab muaj cov dov thiab cov seem sib xyaw ua ke ntawm peb daim hlau welded. I-beams yog tag nrho cov dov seem. Vim tias cov cuab yeej siv tsis zoo, sab hauv ntawm lub 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 me), nws yog ib qho tsim nyog yuav 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-zoo li tus hlau uas tuaj yeem tsim nyob rau hauv Suav teb yog 800mm, uas tuaj yeem tsuas yog welded ua ke seem.
4. Sab ntev ntawm I-nqaj me me thiab qhov siab yog qhov loj, yog li nws tsuas tuaj yeem dais lub zog ntawm ib qho kev taw qhia.
5. Lub H-shaped steel groove yog qhov sib sib zog nqus thiab tuab, thiab tuaj yeem tiv taus lub zog hauv ob qho kev qhia.
6. Nrog rau txoj kev loj hlob ntawm steel qauv vaj tse, tsuas yog I-beams tsis txaus, uas yog, thickened I-beams, uas yog ib qho yooj yim mus poob stability thaum siv nyob rau hauv load-bearing txhua.
7. I-beams tsuas yog siv tau rau cov kab teeb, thaum H-beams tuaj yeem siv rau cov khoom siv thauj khoom-cov kabmob.
8. H-zoo li tus hlau yog ib qho kev lag luam cross-sectional steel nrog cov khoom siv zoo dua li I-shaped steel. Nws yog lub npe vim hais tias nws cov duab ntoo khaub lig yog tib yam li tsab ntawv Askiv "H". Lub flange ntawm qhov kub-kuav los tiag H-nqaj yog dav dua li I-beam, nrog ntau dua lateral tawv thiab muaj zog khoov tsis kam. Nyob rau hauv tib lub specification, qhov theoretical hnyav ntawm H-beam yog sib dua li ntawm I-beam.
9. Lub flange ntawm I-beam yog tuab ntawm lub vev xaib ntawm qhov sib txawv ntawm qhov hnav thiab nyias rau sab nraud; Lub flange ntawm H-beam yog qhov hnav tsis tu ncua.
10. HW, HM, thiab HN yog cov npe dav dav rau H-beams, thiab H-beams yog welded; HW, HM, thiab HN yog kub dov.
11. HW txhais tau hais tias qhov siab ntawm H-shaped steel yog qhov sib npaug ntawm qhov dav ntawm flange; nws yog tsuas yog siv rau steel core kab nyob rau hauv lub zog pob zeb thav duab qauv kab, tseem hu ua txhav steel kab; nws yog tsuas yog siv rau txhua kab hauv steel qauv.
12. HM txhais tau hais tias qhov piv ntawm H-shaped steel qhov siab rau flange dav yog kwv yees li 1.33 ~ 1.75; Feem ntau nyob rau hauv steel qauv: siv raws li steel ncej kab, thiab siv raws li ncej kab teeb nyob rau hauv thav duab qauv bearing dynamic loads. Piv txwv li: ntaus ntawv platform.
13. HN txhais tau hais tias qhov piv ntawm H-beam qhov siab rau flange dav yog ntau dua los yog sib npaug rau 2, feem ntau yog siv rau kab teeb; Kev siv I-beam yog sib npaug rau HN-beam.
