1, H-beam belongs rau qhov kev txiav nyiaj txiag (lwm yam txias-tsim nyias-walled steel, siab steel phaj, thiab lwm yam), vim yog qhov tsim nyog cov duab ntawm ntu ntu, lawv tuaj yeem ua rau cov hlau siab dua los ua lub luag haujlwm. hauv kev ua tau zoo, txhim kho lub peev xwm load-bearing. Qhov sib txawv ntawm qhov zoo tib yam I-beam yog h-beam flange widening, thiab sab hauv thiab sab nrauv feem ntau yog sib npaug, yog li nws tuaj yeem yooj yim siv lub zog siab bolts thiab lwm yam khoom siv txuas nrog. Nws qhov loj me yog cov qauv tsim nyog, ua tiav cov qauv, yooj yim rau kev tsim thiab xaiv.
2, I-beam steel, txawm tias zoo tib yam lossis lub teeb, vim qhov loj ntawm ntu ntu yog qhov siab, nqaim, yog li lub sijhawm ntawm inertia ntawm ob lub tsho tseem ceeb ntawm qhov sib txawv ntawm qhov sib txawv yog qhov loj, yog li ntawd, feem ntau tuaj yeem ua tau. tsuas yog siv ncaj qha rau kev khoov hauv lub dav hlau ntawm nws lub vev xaib lossis nws cov muaj pes tsawg leeg ntawm lattice force cov tswv cuab. Axial compression cov tswv cuab los yog perpendicular mus rau lub dav hlau ntawm lub vev xaib thiab cov tswv cuab bending yuav tsum tsis txhob siv, uas ua rau nws nyob rau hauv daim ntawv thov muaj kev txwv loj.
3, H-beam flange yog sib npaug thickness, dov seem, muaj 3 daim hlau welded los ntawm kev sib xyaw ua ke ntawm hla ntu. I-beam yog dov hla ntu, vim cov txheej txheem tsim khoom tsis zoo, sab hauv ntug ntawm flange muaj 1:10 txoj kab nqes. H-beam dov yog qhov sib txawv ntawm qhov zoo tib yam I-nqaj tsuas yog nrog cov kab rov tav yob, vim nws qhov dav dua flange thiab tsis muaj txoj kab nqes (los yog txoj kab nqes me me), yog li nws yog ib qho tsim nyog los teeb tsa ib pawg ntsug yob tib yam. lub sij hawm rau dov dov, yog li nws cov txheej txheem dov thiab cov cuab yeej siv tau ntau dua li cov dov zeb zoo tib yam. Kev tsim khoom hauv tsev ntawm qhov loj dov h-beam qhov siab ntawm 800mm, ntau tshaj li tsuas yog welded ua ke seem. Tuam Tshoj tus kub dov H-beam lub teb chaws tus qauv (GB/T11263-1998) H-beam muab faib ua peb pawg ntawm nqaim flange, dav flange thiab steel pawg, uas yog coded li hz, hk thiab hu. nqaim flange H-beam yog haum rau kab teeb los yog compression dabtsi yog khoov cov tswv cuab, thaum lub dav flange h-beam thiab h-beam pawg yog haum rau axial compression cov tswv cuab los yog compression dabtsi yog khoov cov tswv cuab. I-beams yog qis dua rau h-beams ntawm w, ix, thiab iy rau qhov hnyav sib npaug piv rau h-beams.
