Vim li cas peb thiaj yuav tsum xaiv H-beam?
1. Cov txiaj ntsig thiab kev ua haujlwm ntawm H-beam yog dab tsi?
Cov txiaj ntsig ntawmH-beam:
Cov flanges dav dav muab kev tiv thaiv khoov thiab ruaj khov, tiv taus cov nra hnyav ntsug; lub web siab dua ua kom muaj kev tiv thaiv shear zoo. Tus qauv tsim no ua tiav kev siv cov khoom siv siab heev, sib dua li cov seem khov kho ntawm tib lub peev xwm thauj khoom, thiab txo qhov hnyav thiab tus nqi ntawm cov qauv. Qhov tseem ceeb tshaj, nws txoj kev tsim flange dav ua rau kev ua haujlwm ntawm cov axes muaj zog thiab tsis muaj zog zoo sib xws, thiab thaum siv ua kem, nws muaj kev ruaj khov zoo heev thiab tuaj yeem tiv taus cov zog sab nraud. Tsis tas li ntawd, qhov dav thiab tiaj tiaj flange nto ua rau kev sib txuas rau lwm yam khoom (welding lossis bolting), thiab qhov loj me kuj ua rau kev tsim qauv thiab kev tsim kho yooj yim. Nws qhov kev ua tau zoo thiab kev siv nyiaj ua rau nws yog qhov profile zoo tshaj plaws rau cov khoom beam thiab kem hauv cov tsev niaj hnub thiab cov qauv engineering.
Kev ua haujlwm ntawm H-beam:
Cov qauv tsev: Lawv ua haujlwm ua cov ntoo thiab cov kem hauv cov chaw tsim khoom lag luam thiab cov tsev siab, ua rau muaj qhov chaw ntev, tsis muaj kem (xws li cov chaw tsim khoom thiab cov tsev nyob). Lawv qhov kev tawv tawv sab nraud ua rau lawv tsim nyog siv rau hauv thaj chaw uas muaj av qeeg.
Kev Tsim Kho Vaj Tse: Lawv siv rau hauv cov ntawv thov loj lossis cov khoom hnyav xws li cov choj, cov chaw nres nkoj, thiab cov teeb meem kev loj, nrog rau cov pawg txhawb nqa hauv cov haujlwm hauv av.
Cov khoom siv hnyav thiab kev thauj mus los: Lawv txhawb nqa cov thav duab ntawm tsheb ciav hlau thiab nkoj, nrog rau cov tshuab hnyav, ua kom muaj kev ruaj khov ntawm cov qauv.
Yuav ua li cas xaiv H-beam?
1.Txiav txim siab txog cov kev ntsuas ntawm seem hla
Kev Txheeb Xyuas Qauv (siv GB/T 11263 ua piv txwv):
HW (Flange Dav)Hlau zoo li tus H): Qhov dav ntawm flange ≈ qhov siab ntawm seem, tsim nyog rau cov kem (muaj zog tiv taus biaxial buckling).
HM (Nruab Nrab Flange H-puab Hlau): Qhov dav ntawm flange yog qhov nruab nrab, tsim nyog rau ob qho tib si beam thiab kem daim ntawv thov.
HN (Cov Hlau Uas Zoo Li Lub Flange Narrow H): Cov flanges nqaim thiab cov webs siab, tsim rau beams (tsis yooj yim khoov).
Piv txwv txog kev qhia tshwj xeeb:
HN400 × 200: Qhov siab ntawm seem 400 hli, qhov dav ntawm flange 200 hli.
Nyiam cov qauv txheem (tus nqi qis dua thiab kev yuav khoom yooj yim dua).
2. Kev Xaiv Qib Khoom Siv
Cov Khoom Siv Hlau Feem Ntau:
Q235B: Lub teeb thauj khoom, cov ntawv thov pheej yig.
Q355B (yav tas los hu ua Q345): Qhov kev xaiv tseem ceeb, nrog lub zog siab thiab kev siv nyiaj zoo heev (pom zoo).
Q420B: Cov khoom hnyav, cov qauv ntev (xws li cov choj thiab cov crane beams Hoobkas).
Cov Chaw Tshwj Xeeb:Cov hlau uas tiv taus huab cua (xws li Q355NH) raug pom zoo rau cov chaw uas muaj xeb. Cov txheej tiv thaiv hluav taws yog qhov yuav tsum tau rau cov chaw uas kub heev.
3. Kev Txhim Kho Kev Lag Luam
Qhov Hnyav ntawm Chav Khoom: Piv qhov sib piv ntawm "qhov hnyav ib 'meter' rau qhov muaj peev xwm nqa tau" ntawm cov qauv sib txawv, muab qhov tseem ceeb rau cov ntu hla uas ua haujlwm tau zoo.
Kev Muaj Peev Xwm Ua Lag Luam: Tsis txhob siv cov lus qhia tshwj xeeb uas tsis nrov (uas muaj lub sijhawm ua khoom ntev thiab tus nqi siab).
Cov Nqi Tiv Thaiv Kev Xeb: Siv cov hlau H-beam uas tau galvanized kub rau cov qauv sab nraum zoov kom txo tau kev saib xyuas tas mus li.
