Hauv kev tsim cov qauv hlau, H-beams thiab I-beams yog cov khoom tseem ceeb. Qhov sib txawv ntawm cov duab seem, qhov loj me thiab cov khoom siv kho tshuab thiab thaj chaw siv ntawm cov ntsiab lus yuav tsum cuam tshuam ncaj qha rau cov cai xaiv engineering.
Hauv kev xav, qhov sib txawv ntawm I-beams thiab H-beams, cov duab, kev tsim kho, ntawm lub dav hlau no yog cov flanges sib luag, Ibeams uas tapers yog li qhov dav flange txo qis nrog qhov deb ntawm lub web.
Hais txog qhov loj me, H-beams tuaj yeem ua nrog ntau yam flange dav thiab web thicknesses kom tau raws li qhov xav tau sib txawv, thaum qhov loj me ntawm I-beams yog ntau dua lossis tsawg dua sib xws.
Nyob rau hauv cov nqe lus ntawm kev ua tau zooHlau H Beamzoo dua hauv kev tiv thaiv torsional thiab tag nrho rigidity nrog nws cov symmetrical cross-sectoin, I beam zoo dua hauv kev tiv thaiv bending rau cov khoom thauj raws lub axis.
Cov zog no tau pom tseeb hauv lawv daim ntawv thov: LubH seem Beamtuaj yeem pom muaj nyob rau hauv cov tsev siab, cov choj, thiab cov khoom siv hnyav, thaum lub I beam ua haujlwm zoo hauv kev tsim kho hlau sib dua, cov thav tsheb, thiab cov beams luv luv.
| Qhov Loj Sib Piv | H-beam | I-beam |
| Qhov tsos | Cov qauv biaxial "H" no muaj cov flanges sib luag, tuab sib npaug rau lub vas, thiab kev hloov pauv ntsug du mus rau lub vas. | Ib qho uniaxial symmetrical I-seem nrog cov flanges tapered tapering los ntawm lub hauv paus web mus rau ntug. |
| Cov yam ntxwv ntawm qhov ntev | Cov lus qhia yooj ywm, xws li qhov dav flange thiab qhov tuab ntawm lub vev xaib uas hloov kho tau, thiab kev tsim khoom tshwj xeeb npog ntau yam kev teeb tsa. | Qhov ntev ntawm cov khoom sib txawv, uas muaj qhov ntev ntawm ntu. Kev hloov kho tau txwv, nrog rau ob peb qhov loj me uas ruaj khov uas muaj tib qhov siab. |
| Cov Khoom Siv Kho Tshuab | Kev nruj torsional siab, kev ruaj khov zoo heev, thiab kev siv cov khoom siv siab ua rau muaj peev xwm thauj khoom ntau dua rau tib qhov ntev ntawm qhov seem. | Kev ua tau zoo heev ntawm kev khoov ib sab (txog lub axis muaj zog), tab sis tsis ruaj khov thiab tsis nyob sab nraud, xav tau kev txhawb nqa lossis kev txhawb nqa sab. |
| Cov Ntawv Thov Engineering | Haum rau cov khoom hnyav, qhov ntev ntev, thiab cov khoom nyuaj: cov thav duab tsev siab, cov choj ntev, cov tshuab hnyav, cov chaw tsim khoom loj, cov chaw ua yeeb yam, thiab ntau ntxiv. | Rau cov khoom thauj me me, luv luv, thiab kev thauj khoom ib sab: cov hlau purlins sib dua, cov ncej rails, cov qauv pabcuam me me, thiab cov kev txhawb nqa ib ntus. |
