Lub flange ntawm H-zoo li tus hlau yog sib npaug los yog 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 tau hu ua parallel flange I- steel. Lub thickness ntawm lub vev xaib ntawm H-zoo li tus hlau yog me dua li qhov zoo tib yam kuv- kab teeb nrog tib qhov siab ntawm lub vev xaib, thiab qhov dav ntawm lub flange 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. 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 qub kuv-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 nws superior kev ua tau zoo, tuaj yeem txhim kho cov kabmob muaj peev xwm zoo li qub I{12}} hlau, txuag hlau 10% ~ 40%. H- cov hlau zoo li muaj flange dav, nyias lub vev xaib, ntau qhov tshwj xeeb, thiab siv tau yooj yim, uas tuaj yeem txuag tau 15% txog 20% ntawm cov hlau hauv ntau cov qauv truss. Vim tias nws cov flange yog sib npaug 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 cov vuam thiab riveting workload, thiab tuaj yeem ua kom nrawm nrawm ntawm qhov project thiab ua kom lub sijhawm siv sijhawm luv.
H-puab steel yog dav siv nyob rau hauv: ntau yam civil thiab industrial vaj tse; Ntau yam ntev -span industrial nroj tsuag thiab niaj hnub siab- cov tsev nce siab, tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam uas nquag seismic kev ua si thiab kub kub ua hauj lwm tej yam kev mob; Cov choj loj uas muaj peev xwm loj, tus ntoo khaub lig zoo -section stability thiab loj ncua yuav tsum tau; Cov khoom siv hnyav; Txoj kev loj; Nkoj pob txha; Kev txhawb nqa kuv; Kev kho lub hauv paus thiab kev tsim vaj tse; Ntau yam tshuab Cheebtsam.
Thoob ntiaj teb, cov qauv khoom ntawm H- zoo li cov hlau tau muab faib ua ob pawg: imperial system thiab metric system. Lub tebchaws United States, lub tebchaws United Kingdom thiab lwm lub teb chaws siv lub British system, Tuam Tshoj, Nyiv, Lub teb chaws Yelemees thiab Russia thiab lwm lub teb chaws siv lub metric system, txawm hais tias lub British system thiab cov metric system siv txawv units ntawm kev ntsuas, tab sis feem ntau ntawm cov H-zoo li tus hlau yog qhia nyob rau hauv plaub qhov ntev, namely: lub web qhov siab H, flange dav b, web thickness d thiab flange thickness t. Txawm hais tias lub teb chaws thoob ntiaj teb muaj ntau txoj hauv kev los qhia qhov loj ntawm H-beam steel specifications. Txawm li cas los xij, tsis muaj qhov sib txawv me ntsis ntawm qhov loj me thiab qhov siab ntev ntawm cov khoom tsim.
