Hauv kev tsim cov qauv hlau, H-beams thiab I-beams yog qhov tseem ceeb ntawm cov kabmob. Qhov sib txawv ntawm qhov sib txawv, qhov loj me thiab cov khoom siv kho tshuab thiab daim ntawv thov ntawm cov kev kawm yuav tsum cuam tshuam ncaj qha rau cov kev cai xaiv engineering.
Raws li txoj cai, qhov sib txawv ntawm I-beams thiab H-beams, cov duab, kev tsim kho, ntawm lub dav hlau load-bearing caij no yog parallel flanges, Ibeams uas tapers yog li qhov flange dav txo nrog kev ncua deb ntawm lub vev xaib.
Hais txog qhov loj me, H-beams tuaj yeem ua nrog ntau yam flange widths thiab web thicknesses kom tau raws li qhov xav tau sib txawv, thaum qhov loj ntawm I-beams ntau dua los yog tsawg dua.
Hais txog kev ua haujlwm TheHlau H Beamyog zoo dua nyob rau hauv torsional kuj thiab zuag qhia tag nrho rigidity nrog nws symmetrical cross-sectoin, lub I beam yog zoo dua nyob rau hauv khoov kuj rau loads raws axis.
Cov kev ua tau zoo no tau tshwm sim hauv lawv cov kev siv: CovH Section Beamtuaj yeem pom nyob rau hauv high-rise, txuas hniav, thiab cov khoom siv hnyav, thaum lub nqaj kuv ua haujlwm zoo hauv kev tsim kho lub teeb steel, tsheb thav duab, thiab cov kab hluav taws xob luv luv.
| Sib piv Dimensions | H-beam | Kuv-beam |
| Qhov tshwm sim | Qhov no biaxial "H"-zoo li tus qauv nta sib npaug flanges, sib npaug thickness rau lub web, thiab ib tug du ntsug hloov mus rau lub web. | Ib qho uniaxially symmetrical I-section nrog tapered flanges tapering los ntawm lub vev xaib hauv paus mus rau cov npoo. |
| Yam ntxwv Dimensional | Saj zawg zog specifications, xws li adjustable flange dav thiab web thickness, thiab kev cai ntau lawm npog ib tug ntau yam ntawm tsis. | Modular qhov ntev, tus yam ntxwv los ntawm qhov ntev ntawm ntu. Adjustability yog txwv, nrog ob peb qhov ntau thiab tsawg ntawm tib qhov siab. |
| Mechanical Properties | High torsional stiffness, zoo tag nrho kev ruaj ntseg, thiab cov khoom siv siab siv cov khoom muaj peev xwm ntau dua load-bearing muaj peev xwm rau tib qhov sib txawv ntawm qhov ntev. | Zoo heev unidirectional dabtsi yog khoov kev ua tau zoo (txog lub axis muaj zog), tab sis tsis zoo torsional thiab tawm-ntawm-lub dav hlau stability, yuav tsum tau lateral kev txhawb los yog ntxiv dag zog. |
| Kev Siv Engineering | Haum rau kev thauj khoom hnyav, kev ncua ntev, thiab kev thauj khoom tsis yooj yim: cov tsev ua haujlwm siab, cov choj ntev ntev, cov tshuab hnyav, cov chaw tsim khoom loj, cov rooj sib tham, thiab lwm yam. | Rau lub teeb loads, luv luv, thiab unidirectional loading: lub teeb yuag steel purlins, ncej rails, me me auxiliary qauv, thiab ib ntus kev txhawb nqa. |
