Hlau H Beam, lub npe rau lawv cov seem "H", yog cov khoom siv hlau ua haujlwm tau zoo thiab pheej yig nrog cov txiaj ntsig xws li kev tiv taus khoov muaj zog thiab cov nplaim flange sib luag. Lawv siv dav hauv ntau qhov chaw, suav nrog kev tsim kho, choj, thiab kev tsim khoom siv tshuab. Ntawm ntau tus qauv H-beam, H-beams teev nyob rau hauv ASTM A992 sawv tawm rau lawv cov kev ua tau zoo tshaj plaws.
ASTM A992 H-beams yog cov hlau siv feem ntau hauv cov tsev hauv Tebchaws Meskas, muab lub zog siab thiab kev tawv zoo heev. Nrog rau qhov tsawg kawg nkaus ntawm 50 ksi (kwv yees li 345 MPa) thiab lub zog tensile ntawm 65 thiab 100 ksi (kwv yees li 448 thiab 690 MPa), lawv tuaj yeem tiv taus cov khoom hnyav thiab ua kom pom kev vuam zoo heev thiab kev tiv thaiv av qeeg. Qhov no ua rauASTM A992 H beamscov khoom siv xaiv rau cov haujlwm tseem ceeb xws li cov tsev siab thiab cov choj loj.
Ntawm ntau qhov ntau thiab tsawg ntawm ASTM A992 H-beam, 6 * 12 thiab 12 * 16 qhov ntau thiab tsawg yog qhov feem ntau.
6 * 12 Hlau H Beam muaj qhov dav flange nqaim thiab qhov siab nruab nrab, muab kev siv nyiaj txiag zoo heev thiab kev siv tau zoo. Hauv kev lag luam kev tsim kho, lawv feem ntau siv rau hauv cov khoom siv xws li cov nqaj theem nrab thiab purlins hauv cov tsev nyob thiab cov tsev lag luam, sib koom ua ke cov khoom thauj hauv tsev thiab ua kom muaj kev ruaj khov ntawm cov qauv. Hauv cov nroj tsuag me me, 6 * 12 H-beams kuj tseem siv los txhawb cov qauv ru tsev thiab ua tau raws li qhov yuav tsum tau ua.
12 * 16 Kub Rolled H Beam muab cov qhov loj dua ntawm qhov hla thiab muaj peev xwm thauj khoom ntau dua. Hauv kev tsim kho choj loj, lawv ua haujlwm ua cov nqaj hlau thauj khoom tseem ceeb, nqus cov khoom thauj tsheb thiab kev ntxhov siab ntawm ib puag ncig ntuj, ua kom lub zog thiab kev ruaj khov ntawm tus choj. Hauv cov tsev siab heev, 12 * 16 H-beams feem ntau siv rau hauv cov chaw tseem ceeb xws li cov raj tseem ceeb thiab cov ncej ncej, muab kev txhawb nqa zoo rau tag nrho cov qauv thiab tiv thaiv nws los ntawm kev puas tsuaj ntuj tsim xws li cua thiab av qeeg. Ntxiv mus, 12 * 16 H-beams kuj tseem ua lub luag haujlwm tseem ceeb hauv cov haujlwm loj xws li cov khoom siv lag luam loj thiab cov chaw nres nkoj.
Hauv ntej, ASTM A992 H-beams, nrog lawv cov kev ua tau zoo heev thiab ntau yam qhov loj me, ua lub luag haujlwm tseem ceeb hauv ntau yam haujlwm tsim kho. 6 * 12 thiab 12 * 16 H-beams, nrog lawv cov yam ntxwv tshwj xeeb, ua tau raws li ntau yam kev xav tau ntawm ntau yam haujlwm, tsav tsheb kev txhim kho tas mus li ntawm kev tsim kho niaj hnub.
Cov ntsiab lus saum toj no qhia txog cov yam ntxwv ntawm ASTM A992 Carbon Steel H Beam, los ntawm kev ua tau zoo mus rau kev siv. Yog tias koj xav ntxiv lwm yam lus qhia lossis cov xwm txheej ntawm daim ntawv thov, thov qhia rau kuv paub.
