I-beam Kev ntsuas
I-beams feem ntau txheeb xyuas los ntawm lawv cov npe, uas suav nrog tsab ntawv "W" ua raws li tus lej. Tus lej qhia tau hais tias lub beam lub nominal qhov tob hauv inches. Ib qho I-beam qhov ntev kuj suav nrog nws qhov dav flange ( ntsuas kab rov tav) thiab web thickness ( ntsuas ntsug).
Xav txog tus qauv W10x30 I-beam:
Qhov tob (web qhov siab): 10 "
Flange dav: 5.75 nti.
Web thickness: feem ntau nyob ib ncig ntawm 0.43 ntiv tes.
Qhov hnyav ntawm ib kab ko taw ntawm W10x30 I-beam yog kwv yees li 30 phaus.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias I-beam qhov ntev thiab qhov hnyav tuaj yeem sib txawv nyob ntawm cov qauv hauv cheeb tsam thiab cov chaw tsim khoom. Kuj tseem muaj cov qauv metric rau I-beams, xws li "HE" series (HEA, HEB, HEM), uas siv cov qauv sib txawv me ntsis raws li kev ntsuas ntsuas.
I-beams tuaj nyob rau hauv ntau qhov ntau thiab tsawg kom tau raws li qhov sib txawv load-bearing xav tau thiab cov qauv tsim. Thaum i-beam qhov ntau thiab tsawg tuaj yeem sib txawv nyob ntawm cov qauv hauv cheeb tsam thiab cov chaw tsim khoom, muaj qee qhov kev siv tus qauv ntawm i-beam. Nov yog qee qhov piv txwv:
W4x13: Qhov no I-nqaj yog 4 nti tob thiab 4 nti dav ntawm flanges. Qhov hnyav ib ko taw yog li 13 phaus.
W8x18: Nrog rau qhov tob ntawm 8 ntiv tes thiab flange dav ntawm 4.625 ntiv tes, qhov no I-nqaj hnyav kwv yees li 18 phaus ib ko taw.
W10x30: Qhov I-nqaj no muaj qhov tob ntawm 10 ntiv tes, qhov dav ntawm 5.75 ntiv tes, thiab hnyav ib ncig ntawm 30 phaus ib ko taw.
W12x53: Nrog rau qhov tob ntawm 12 ntiv tes thiab flange dav ntawm 6.49 ntiv tes, qhov no I-beam hnyav kwv yees li 53 phaus ib ko taw.
Cov no tsuas yog ob peb tus qauv loj ntawm i-beam; muaj ntau ntau txoj kev xaiv muaj. Thaum txiav txim siab ntawm I-beam loj rau ib daim ntawv thov tshwj xeeb, siv cov khoom siv hluav taws xob engineering, cov qauv hauv zos, lossis cov kws tshaj lij uas muaj ntawv pov thawj kom paub tseeb tias muaj peev xwm thauj khoom txaus thiab kev ua haujlwm zoo.
