1. Cov khoom sib txawv
Ib tug ntev steel bar nrog ib tug I-shaped cross-section.
Nws yog ib qho kev lag luam steel nrog ntau qhov chaw faib khoom zoo dua thiab tsim nyog lub zog-rau-qhov hnyav piv. Nws tus ntoo khaub lig yog tib yam li tsab ntawv Askiv "H" thiab nws muaj npe tom qab nws.
2. Cov haujlwm sib txawv
Kuv-beam
Sab ntev yog me me thiab qhov siab yog loj, thiab nws tsuas tuaj yeem tiv taus quab yuam hauv ib qho kev taw qhia. Yog li ntawd, I-beams yog dav siv nyob rau hauv ntau lub tsev, txuas hniav, tsheb, kev txhawb nqa, machinery, thiab lwm yam.
H-beam
Qhov zawj yog qhov tob thiab tuab, thiab nws tuaj yeem tiv taus lub zog ntawm ob qho tib si. Qhov loj ntawm H-zoo li tus hlau ua cov qauv tsim nyog nrog cov qauv ua tiav, ua kom yooj yim rau kev tsim thiab xaiv.
3. Ntau pawg
(1) I-beams feem ntau muab faib ua I-beams zoo tib yam, lub teeb I-beams thiab wide-flange I-beams.
(2) Raws li qhov siab piv ntawm flange rau lub vev xaib, nws muab faib ua dav, nruab nrab thiab nqaim dav flange I-beams. Qhov tshwj xeeb ntawm thawj ob yam khoom yog No. 10-60, uas txhais tau hais tias qhov sib thooj qhov siab yog 10-60 cm. Nyob rau tib qhov siab, lub teeb I-beams muaj qhov nqaim flanges, nyias webs, thiab lub teeb yuag. Dav flange I-beam, tseem hu ua H-shaped beam, yog tus cwj pwm los ntawm qhov sib npaug ntawm qhov sib npaug thiab tsis muaj nqes hav ntawm sab hauv ntawm cov outriggers.
Nws yog ib qho kev lag luam hlau, dov rau ntawm plaub-cov menyuam universal dov zeb, tseem hu ua "universal I-beam". Ordinary I-beam thiab teeb I-beam tau tsim cov qauv hauv tebchaws.
2. H-shaped steel kev faib tawm:
