Kev cai I-beam
Lus piav qhia luv luv:
I-beam feem ntau muab faib ua I-beam zoo tib yam, lub teeb I-beam thiab dav flange I-beam.Raws li qhov siab piv ntawm flange rau lub vev xaib, nws muab faib ua dav, nruab nrab thiab nqaim flange I-beams.Qhov tshwj xeeb ntawm thawj ob yog 10-60, uas yog, qhov sib thooj qhov siab yog 10 cm-60 cm.Nyob rau tib qhov siab, lub teeb I-beam muaj nqaim flange, nyias lub web thiab lub teeb yuag.Dav flange I-beam, tseem hu ua H-beam, yog tus cwj pwm los ntawm ob txhais ceg sib luag thiab tsis muaj kev xav ntawm sab hauv ntawm ob txhais ceg.Nws belongs rau kev lag luam seem hlau thiab dov rau plaub lub siab universal zeb, yog li nws tseem hu ua "universal I-beam".Ordinary I-beam thiab teeb I-beam tau tsim cov qauv hauv tebchaws.
Cov yam ntxwv ntawm kev siv
Txawm hais tias I-section steel yog zoo tib yam los yog lub teeb, vim hais tias cov seem loj yog qhov siab thiab nqaim, lub sij hawm ntawm inertia ntawm ob lub ntsiab axes ntawm seem yog qhov sib txawv heev, yog li nws tsuas yog siv ncaj qha rau cov tswv cuab khoov hauv lub dav hlau. lawv lub vev xaib lossis daim ntawv lattice stressed cov tswv cuab.Nws tsis haum rau axial compression cov tswv cuab lossis cov tswv cuab nrog khoov perpendicular rau lub vev xaib dav hlau, uas ua rau nws txwv tsis pub dhau ntawm daim ntawv thov.I-beam yog dav siv nyob rau hauv lub tsev los yog lwm yam hlau lug.
Vim tias qhov loj me me ntawm qhov loj me ntawm I-nqaj thiab lub teeb I-beam, lub sijhawm ntawm inertia ntawm ob lub ntsiab axes ntawm seem yog qhov sib txawv heev, uas ua rau nws txwv tsis pub dhau ntawm daim ntawv thov.Kev siv I-beam yuav tsum raug xaiv raws li qhov yuav tsum tau ua ntawm cov duab kos duab.
Thaum xaiv I-beam hauv cov qauv tsim, tsim nyog I-nqaj yuav tsum raug xaiv raws li nws cov khoom siv, tshuaj lom neeg, weldability thiab cov qauv loj.
