H beamCov ncej hlau, tseem hu ua cov ncej hlau thoob ntiaj teb lossis I-beams, yog cov khoom tseem ceeb hauv kev tsim kho niaj hnub no. Lawv qhov seem zoo li tsab ntawv 'H' lossis 'I'. Cov duab tshwj xeeb no muab qhov sib piv ntawm lub zog thiab qhov hnyav, uas ua rau lawv tsis tseem ceeb rau kev nqa cov khoom hnyav.
Phau ntawv qhia no yuav tshawb nrhiav lub ntiaj teb ntawm cov qauv European H beams. Peb yuav delve rau hauv cov lus qhia, daim ntawv thov, thiab qhov sib txawv tseem ceeb ntawm cov profiles tseem ceeb: HEA, HEB, thiab HEM seem.
Dab tsi yog H Beams?
Cov chaw tsim khoom dov H beams rau hauv cov hlau uas muaj qhov seem uas zoo li tsab ntawv "H." Lawv muaj ob lub sib luag.cov flangestxuas nrog ib qho ntsuglub vas sab. Tus qauv tsim no faib cov khoom thauj tau zoo thiab tiv taus cov zog khoov hauv ntau qhov kev taw qhia. Cov txheej txheem kub-dov tsim khoomCov Hlau CarbonH beam, ua rau cov qauv sib xws nrog cov khoom siv kho tshuab zoo heev.
Cov txiaj ntsig tseem ceeb ntawm H Beam Structures
Muaj Peev Xwm Thauj Khoom Tau Siab:Tus qauv H no faib cov hlau tau zoo, thiab feem ntau cov khoom siv nyob deb ntawm nws qhov chaw nruab nrab. Qhov no ua rau lub zog tseem ceeb (lub zog inertia thiab modulus ntawm seem) siab tshaj plaws, ua rau nws tuav tau cov khoom hnyav.
Kev siv tau ntau yam:Haum rau cov kem, beams, purlins, thiab ntau yam kev sib xyaw ua ke.
Kev Siv Nyiaj Zoo:Kev siv cov khoom siv tsawg dua rau lub zog ua tiav ua rau muaj kev tsim qauv pheej yig
Yooj yim ntawm kev tsim khoom:Yooj yim rau vuam, ntsia hlau, thiab hloov kho rau cov kev xav tau tshwj xeeb.
Kev Ntseeg Tau Pom Zoo:Cov qhov ntev thiab kev ua tau zoo uas kwv yees tau hauv qab kev ntxhov siab
Kev Sib Sib Zog: European Standard H Beams - HEA, HEB, HEM
Cov qauv European H beams raug faib ua pawg los ntawm lawv qhov sib piv thiab qhov hnyav ib 'meter'. Cov koob feem ntau yog:
HEA Beams (Lub Teeb Series)
Cov kab hluav taws xob HEA yog cov yam ntxwv los ntawm qhov sib txawvcov flanges nqaim dua thiab nyias duapiv rau lawv qhov siab. Lawv feem ntau hu ua "light series" lossis "IPE-like" light h-beams tab sis nrog cov flanges dav dua.
Cov Ntawv Thov Ib Txwm Muaj:Cov ntsiab lus ntawm cov qauv theem ob, purlins, kem sib dua, thiab cov ntawv thov uas xav tau cov khoom thauj nruab nrab.
Qhov Tseem Ceeb:Pheej yig dua hauv qhov hnyav rau qhov siab, nyiam qhov tsis kam khoov txog qhov loj axis.
HEB Beams (Nruab Nrab/Txheej Txheem Series)
HEB beams sawv cev rau covtus qauv lossis nruab nrab series-nruab nrab h-beam, muajcov flanges dav dua thiab tuab duadua li HEA seem ntawm tib qhov siab nominal.
Cov Ntawv Thov Ib Txwm Muaj:Cov ncej thiab cov ntoo khaub lig uas tuav tau lub nra hnyav hauv cov tsev, cov thav duab kev lag luam, thiab cov choj. Qhov no yog cov koob siv feem ntau rau kev tsim kho dav dav.
Qhov Tseem Ceeb:Kev ua tau zoo heev txhua yam, muab kev tiv taus zoo rau ob qho tib si khoov thiab compression, ua rau lawv zoo tagnrho rau cov kem.
HEM Beams (Hnyav Series)
Cov HEM beams yog covhnyav thiab muaj zogcov tswv cuab ntawm tsev neeg. HEM Beams yog cov h-beams hnyav thiab cov h-beam thauj khoom siab. Lawv muaj lubcov flanges dav tshaj plaws thiab tuab tshaj plawsntawm peb, nrog rau lub web thickness kuj nce ntxiv ntau.
Cov Ntawv Thov Ib Txwm Muaj:Cov ncej ruaj khov hauv cov tsev ntau txheej, kev txhawb nqa lub hauv paus rau cov tshuab hnyav, cov haujlwm tsim kho vaj tse (xws li cov ncej), thiab txhua yam qauv uas raug kev thauj khoom hnyav heev.
Qhov Tseem Ceeb:Muaj peev xwm thauj khoom axial zoo heev thiab ruaj khov. Lawv qhov dav ntawm flange kuj tseem muab kev ruaj khov zoo tiv thaiv kev khoov.
Cov Kev Xav Tseem Ceeb rau Kev Xaiv
Kev xaiv ntawm HEA, HEB, thiab HEM beams yuav tsum tau ua tib zoo soj ntsuam kev tsim kho. Cov yam tseem ceeb suav nrog:
Hom Thauj Khoom thiab Qhov Loj:Cov khoom thauj axial (compressive) nyiam cov ntu HEB lossis HEM, thaum cov xwm txheej khoov ntshiab yuav siv HEA lossis HEB.
Ntev Ntev:Cov ntu ntev dua feem ntau xav tau cov ntu tob dua rau kev tiv taus khoov txaus.
Cov Kev Cai Ruaj Khov:Kev tiv thaiv kev khoov (ob qho tib si hauv zos thiab thoob ntiaj teb) tau txhim kho los ntawm cov flanges thiab webs tuab dua pom nyob rau hauv HEB thiab HEM seem.
Cov Lus Qhia Txog Kev Sib Txuas:Qhov dav thiab tuab ntawm flange cuam tshuam rau kev vuam thiab kev sib txuas bolting.
Cov Kev Txwv ntawm Kev Tsim Kho Vaj Tse:Qhov chaw seem yuav txwv qhov tob lossis qhov dav ntawm seem.
Kev Txhim Kho Tus Nqi thiab Cov Khoom Siv:Lub hom phiaj yog ua kom tau raws li txhua yam kev nyab xeeb thiab kev ua tau zoo nrog rau qhov seem pheej yig tshaj plaws, txo qhov hnyav tag nrho ntawm cov hlau.
Cov Ntawv Thov Siv Hauv Kev Lag Luam
Kev Tsim Kho Vaj Tse:Cov pob txha ntawm cov tsev siab ua lag luam, kev lag luam, thiab kev nyob.
Kev Tsim Kho Choj:Cov girders thiab cov qauv txhawb nqa.
Cov Mezzanines thiab Platforms Muaj Kev Lag Luam:Cov thav duab txhawb nqa rau cov plag tsev siab.
Cov Chaw Tsim Khoom Siv Hnyav:Lub hauv paus ruaj khov rau cov tshuab nias, turbines, thiab cov khoom siv loj.
Cov Txheej Txheem Racking Warehouse:Cov thav duab ncaj nraim rau qhov chaw cia khoom ntau.
Lub Tsheb Thauj Khoom thiab Lub Tsheb Thauj Khoom Chassis:Cov tswv cuab tseem ceeb ntawm lub thav duab longitudinal.
