I-beams muaj ntau yam kev siv tseem ceeb hauv kev lag luam steel kev tsim kho. Lawv feem ntau yog siv los ua kev txhawb nqa tseem ceeb, lossis lub hauv paus ntsiab lus, hauv cov tsev. Steel I-beams ua kom cov qauv kev ncaj ncees nrog lub zog tsis tu ncua thiab kev txhawb nqa. Lub zog loj ntawm I beams txo qhov yuav tsum tau suav nrog ntau cov qauv kev txhawb nqa, txuag lub sijhawm thiab nyiaj txiag, nrog rau ua kom cov qauv ruaj khov. Lub versatility thiab kev cia siab ntawm I-beams ua rau lawv muaj peev xwm txaus siab rau txhua tus tsim.
Feem ntau hu ua "I" beam vim nws cov duab, kab teeb muab kev txhawb nqa zoo thaum siv kab rov tav lossis sawv ua ke. I-beams yog qhov kev xaiv zoo rau cov qauv hlau tsim vim tias I-beam ua rau nws muaj peev xwm tuav tau ntau yam kev thauj khoom. Cov duab ntawm I-beams ua rau lawv zoo heev rau unidirectional dabtsi yog khoov thaum uas tig mus rau lub vev xaib. Kab rov tav flanges tiv thaiv kev txav txav, thaum lub vev xaib tiv thaiv kev ntxhov siab.
Kev nkag siab txog I-beam yog qhov tsim nyog rau cov neeg ua haujlwm hauv tsev niaj hnub lossis cov neeg ua haujlwm tsim kho. Engineers siv I-beams dav hauv kev tsim kho, tsim kab thiab kab teeb ntawm ntau qhov sib txawv, qhov ntau thiab tsawg, thiab qhov tshwj xeeb.
I-beam yog tsim los ntawm dov lossis milling steel uas txhais tau tias I-beam feem ntau txwv los ntawm lub peev xwm lossis qhov loj ntawm cov khoom siv milling.
I-beams tuaj nyob rau hauv ntau yam hnyav, seem qhov tob, flange widths, web thicknesses, thiab lwm yam specifications rau txawv hom phiaj. Thaum xaj I-beams, cov neeg yuav khoom faib lawv los ntawm lawv cov khoom thiab qhov ntev. Piv txwv li, ib qho 11 × 20 I-beam yuav muaj qhov tob 11-inch thiab qhov hnyav ntawm 20 phaus ib ko taw. Cov neeg tsim khoom xaiv qhov loj me ntawm I-beams raws li qhov xav tau ntawm lub tsev tshwj xeeb. Ib tug builder yuav tsum coj ntau yam rau hauv tus account, xws li:
Tus tsim xaiv I-beam nrog lub web thickness uas yuav tsis poob, buckle, los yog ripple nyob rau hauv nruj.
Cov flanges raug xaiv los tiv thaiv buckling hauv zos, sab sab, lossis torsionally.
Tus neeg tsim khoom yuav xaiv lub thickness los txo qhov deformation ntawm lub nqaj.
Ib qho loj thiab nruj yog xaiv los tiv thaiv kev vibrations hauv lub tsev.
Lub zog ntawm I-beam's cross-section yuav tsum ua kom haum rau qhov kev ntxhov siab.
