Lub flange ntawm H-zoo li tus hlau yog thaum uas tig mus lossis ze li ntawm qhov sib npaug ntawm sab hauv thiab sab nraud, thiab qhov kawg ntawm flange yog nyob rau ntawm lub kaum sab xis, yog li nws yog lub npe hu ua parallel flange I-steel.
Lub thickness ntawm lub web ntawm H-zoo li tus hlau yog me dua li ntawm qhov zoo tib yam I-beams nrog tib qhov siab ntawm lub vev xaib, thiab qhov dav ntawm lub flange yog loj dua li qhov zoo tib yam I-beams nrog tib qhov siab ntawm lub vev xaib, yog li nws kuj muaj npe dav-rim I-beams. Kev txiav txim siab los ntawm cov duab, seem modulus, lub sij hawm ntawm inertia thiab coj lub zog ntawm H-beam yog pom tseeb zoo dua li qhov zoo tib yam I-beam nrog tib qhov hnyav.
Siv nyob rau hauv cov kev cai sib txawv ntawm cov qauv hlau, txawm tias nws yog nyob rau hauv dabtsi yog khoov torque, siab load, eccentric load qhia tau hais tias nws superior kev ua tau zoo, tuaj yeem txhim kho cov kabmob muaj peev xwm zoo li qub I-steel, txuag hlau 10% ~ 40%.
H-shaped steel muaj flange dav, nyias lub vev xaib, ntau qhov tshwj xeeb, thiab siv tau yooj yim, uas tuaj yeem txuag tau 15% mus rau 20% ntawm cov hlau hauv ntau cov qauv truss. Vim tias nws cov flange yog sib npaug rau sab hauv thiab sab nraud, thiab ntug kawg yog ntawm lub kaum sab xis, nws yooj yim rau kev sib sau thiab ua ke rau hauv ntau yam khoom, uas tuaj yeem txuag tau li ntawm 25% ntawm vuam thiab riveting workload, thiab tuaj yeem ua kom nrawm nrawm ntawm kev tsim kho. ntawm qhov project thiab shorten lub sij hawm tsim kho.
