H beam yog hom tshiab steel beam rau kev lag luam steel siv. Cov duab ntawm H-beam yog kev lag luam thiab tsim nyog nrog cov khoom siv zoo. Qhov txuas ntxiv ntawm txhua lub ntsiab lus ntawm ntu yog sib xws thiab qhov kev ntxhov siab sab hauv me me thaum dov. Piv nrog cov I-beams zoo tib yam, nws muaj qhov zoo ntawm qhov loj me me, lub teeb yuag, thiab kev txuag hlau, uas tuaj yeem ua rau cov qauv vaj tsev qhov hnyav txo los ntawm 30-40%. Hauv qab no yog cov yam ntxwv tshwj xeeb.
1. wide flange thiab loj lateral rigidity. Muaj zog dabtsi yog khoov tsis kam, txog 5% -10% loj dua I-beam.
2. Ob qhov chaw ntawm flange yog sib npaug rau ib leeg, uas ua rau kev sib txuas, kev ua haujlwm thiab kev teeb tsa yooj yim.c
3. Muab piv nrog welded I-beams, nws muaj qhov zoo ntawm tus nqi qis, siab precision, tsis tshua muaj kev ntxhov siab, tsis xav tau cov khoom siv vuam kim thiab kev soj ntsuam vuam, thiab txuag li 30% ntawm cov qauv steel ntau lawm.
4. Nyob rau hauv tib seem load. Qhov hnyav ntawm kub dov H steel qauv yog 15% -20% sib dua li cov qauv hlau ib txwm muaj.
5. Piv nrog rau cov qauv pob zeb, cov qauv kub-dov H steel tuaj yeem ua rau thaj tsam siv tau los ntawm 6%, thaum cov qauv ntawm tus kheej qhov hnyav yog txo los ntawm 20% -30%, uas txo cov zog sab hauv ntawm cov qauv tsim. .
