H-beams, tseem hu ua H beam steel, yog ib qho kev xaiv rau cov tsev steel, tab sis tsis muaj ib ntu uas ua haujlwm rau txhua qhov project. Lub nqaj siv nyob rau hauv ib lub warehouse thav duab yuav muaj ntau yam kev xav tau los ntawm ib qho siv nyob rau hauv lub dav hlau hangar los yog rhiav kev lag luam.
Qhov kev xaiv los mus rau ntau tshaj qhov ntev teev nyob rau hauv ib lub rooj steel seem. Cov kev xav tau ntawm kev thauj khoom, ncua, qib steel, tus qauv tsim, cov ntsiab lus sib txuas, thiab cov kev xav tau ntawm kev tsim khoom tuaj yeem cuam tshuam rau seem uas tsim nyog. Kev nkag siab txog cov xwm txheej no ua rau nws yooj yim dua los sib piv H- kab teeb thiab xaiv ib ntu uas haum rau qhov project.
H Beam Steel yog dab tsi?
Lub H-beam muaj ob lub flanges thiab lub vev xaib ntsug. Cov flanges feem ntau tiv thaiv kev khoov, thaum lub vev xaib nqa lub zog shear thiab txuas ob lub flanges.
Lub H-zoo li tus tsim tso ntau cov hlau uas nws muaj txiaj ntsig zoo tshaj plaws los tiv thaiv kev khoov. Qhov no muab cov nqaj zoo zog thiab nruj yam tsis tas yuav tsum muaj cov hlau loj. Raws li qhov tshwm sim, H-beams tuaj yeem nqa cov khoom hnyav hnyav thaum ua kom lawv qhov hnyav qis.
Dab tsi yog Cov Khoom Ntawm H-Beams?
Qhov txiaj ntsig tseem ceeb ntawm H-beam yog nws txoj kev ua haujlwm zoo -section. Raws li qhov loj me, nws muaj kev thauj khoom siab -cov kabmob muaj peev xwm, zoo nruj, thiab siv cov khoom siv tau zoo.
Common H-beam khoom muaj xws li:
- Siab khoov tsis kam
- Muaj zog axial load peev
- Zoo nruj
- Ua kom muaj zog - rau - qhov hnyav piv
- Compatibility nrog ob qho tib si bolted thiab welded kev sib txuas
- Muaj nyob rau hauv ntau qhov ntau thiab tsawg thiab qib steel
Vim li no, H-beams ua hauj lwm raws li ob qho tib si ntsug thiab kab rov tav structural tswv cuab: ib kem ntawm ib qhov project, ib tug rafter los yog ru tsev beam nyob rau tom ntej. Ib ntu kev ua tau zoo npaum li cas tseem nyob ntawm seb nws tsim tau li cas, thiab qhov ntawd yog qhov kub - dov thiab welded seem pib sib txawv.
Dab tsi yog Hom H-Beams?
H-beams poob rau hauv ob pawg dav raws li lawv tau tsim.
| Kub-Rolled H-Beam | Welded H-Beam | |
| Nws ua li cas | Rhaub steel dov rau hauv cov duab | Hlau daim hlau txiav thiab welded ua ke |
| Dimension yooj | Standard, tsau profiles | Kev cai qhov tob, flange dav, phaj thickness |
| Zoo tshaj plaws | Standard spans thiab loads | Tsis yog- ntu ntu, cov tswv cuab loj |
| Tus nqi | Feem ntau yog kev lag luam ntau dua | Siab dua, qhia txog kev hloov kho |
Qhov twg tus qauv profile ua tau raws li qhov yuav tsum tau ua, qhov kub - dov feem ntau yog qhov kev xaiv pheej yig dua. Welded seem raug nqi ntau dua, tab sis lawv khwv tau tus nqi ntawd thaum qhov project xav tau ib yam dab tsi sab nraum tus qauv. Lub vev xaib sib sib zog nqus, qhov dav dav, lossis qhov sib txawv tuab sib xyaw ua ke feem ntau tsis yog ib yam dab tsi uas lub tshuab dov ua tawm ntawm lub txee.
Cov ntu uas tau txheeb xyuas raws li W-cov duab (dav-flange) muaj nyob hauv Tebchaws Meskas. Lawv zoo ib yam li H-beam nyob rau hauv cross-section, tab sis los ntawm ib tug cais system. Lub npe ib leeg tsis lav qhov sib npaug qhov ntev lossis cov khoom. Cov neeg yuav khoom yuav tsum sib piv qhov tseeb specification, tsis yog lub npe zoo xwb.
H Beam Steel Ua li cas?
H-beams feem ntau yog tsim los ntawm ob txoj kev: kub dov thiab vuam.
Kub- dov H-beams pib raws li rhuab steel billets. Ib tug series ntawm rollers shape cov billets rau hauv H- zoo li seem, thiab lub zeb ces txias, straightens, soj ntsuam, thiab txiav cov kab tiav mus rau qhov ntev yuav tsum tau.
Welded H-beams pib los ntawm cov hlau phaj. Cov neeg ua haujlwm txiav cov phaj kom loj, muab lawv tso rau hauv H- zoo li seem, thiab txuas lawv ua ke. Lawv mam li ncaj, tshuaj xyuas, txiav, laum, thiab nto - kho cov kab teeb yog tias xav tau.
Txoj kev tsim khoom yog nyob ntawm qhov yuav tsum tau muaj qhov loj me, ntim ntau lawm, qib kev hloov kho, thiab qhov project specifications.
Dab tsi H-Beam Sizes Muaj?
Daim ntawv qhia tag nrho rau H-beam steel npog ntau tshaj qhov tob thiab flange dav. Nws kuj suav nrog web thickness thiab flange thickness. Cov qhov ntev no txiav txim siab cov khoom seem tiag tiag.
Daim duab loj thiab qhov hnyav yog qhov pib muaj txiaj ntsig zoo rau kev sib piv. Tab sis tib lub nominal qhov ntev tsis tas txhais hais tias tib yam nyob rau hauv cov qauv sib txawv. GB, ASTM, thiab EN systems siv ntau txoj kev xaiv. Ib ntu uas zoo li sib npaug ntawm daim ntawv tuaj yeem nqa qhov sib txawv, qhov siab ntev, thiab txawm tias qhov sib txawv ntawm qib steel nyob rau hauv txhua tus qauv. Rau cov haujlwm thoob ntiaj teb, nws tsim nyog lees paub qhov ua tiav cov lus qhia. Tshawb xyuas qhov ntev thiab qib ua ke, tsis yog muab piv rau qhov loj me ib leeg.
Qhov theoretical hnyav ntawm H-beam feem ntau yog los ntawm nws tus ntoo khaub lig-sectional cheeb tsam thiab steel ntom. Qhov tseeb muab qhov hnyav tuaj yeem sib txawv me ntsis nrog rau kev tsim khoom thiab kev tswj hwm tus qauv.
H-Beam siv nyob qhov twg?
H-beams mus rau qhov twg ib qho qauv xav tau ib tus tswv cuab uas tuaj yeem nqa cov khoom tseem ceeb.
Raws li cov kab, lawv hloov ntsug thiab sab loads mus rau hauv lub hauv paus. Lawv tus ntoo khaub lig-section geometry muab lawv lub peev xwm muaj txiaj ntsig tiv thaiv ob qho tib si axial compression thiab khoov thaum seem yog qhov loj me.
Raws li kab teeb lossis rafters, H-beams hla lub ru tsev, hauv pem teb, thiab cov khoom siv thauj khoom hla cov qauv. Lawv kuj muaj nyob rau hauv crane- txhawb nqa cov qauv, platforms, thiab lwm yam kev txhawb nqa khoom siv.
Hauvprefabricated steel tsev, H-beams feem ntau tsim cov ncej thawj. Lawv ua haujlwm nrog purlins, girts, bracing, ru tsev panels, thiab phab ntsa. Cov seem ib lub tsev xav tau nyob ntawm nws qhov dav, qhov siab, qhov hnyav, qhov sib nrug ntawm qhov chaw, qhov qhib, cov khoom siv, thiab cov qauv tsim qauv.
Koj Xaiv txoj cai H-Beam li cas?
Rau qhov tseem ceeb tshaj plaws thaum xaiv H-beam.
Kauj Ruam 1: Txheeb xyuas lub luag haujlwm ntawm tus qauv thiab lub zog qauv
Txheeb xyuas seb tus tswvcuab puas yog lub nqaj nyob rau hauv dabtsi yog khoov, ib kem nyob rau hauv compression, brace nyob rau hauv axial load, los yog ib tug purlin nyob rau hauv lub teeb dabtsi yog khoov. Qhov no txiav txim siab seb cov ntu twg tsim nyog xav txog.
Kauj Ruam 2: Xam cov Loads thiab Forces
Muab cov khoom thauj tuag, nyob load, cua, daus, thiab seismic load raws li txoj cai tswjfwm kom tau txais lub sijhawm tsim, shear, thiab axial quab yuam cov seem yuav tsum nqa.
Kauj ruam 3: Ua ib qho kev xaiv ua ntej
Kwv yees qhov yuav tsum tau muaj qhov loj me los ntawm cov quab yuam, tom qab ntawd kos ib lub rooj steel seem rau tus neeg sib tw. Cov kauj ruam no tsuas yog ib qho screen ntxhib rau seb qhov seem loj txaus.
Kauj Ruam 4: Txheeb xyuas Tshooj
Tshawb xyuas lub zog, tom qab ntawd txhav, tom qab ntawd tag nrho thiab hauv zos stability. Yog tias ib qho kev kuaj tsis ua tiav, rov qab mus rau Kauj Ruam 3 thiab xaiv qhov loj dua.
Kauj Ruam 5: Paub meej cov khoom qib thiab tus qauv
Cov qauv siv tau teev cov khoom siv qib: GB Q235B lossis Q355B hauv Suav teb, ASTM A36 lossis A992 hauv Asmeskas, EN 10025 S235 lossis S355 hauv Tebchaws Europe. Qib teeb tsa lub zog tsim, uas rov qab mus rau qhov loj npaum li cas cov seem yuav tsum yog.
Kauj Ruam 6: Ntsuas tus nqi thiab kev tsim khoom
Sib piv cov neeg sib tw uas dhau ntawm qhov muaj peev xwm ntawm ib kg / m, yooj yim ntawm kev sib txuas, galvanizing thiab hluav taws kub- xav tau kev tiv thaiv, thiab lub sijhawm ua cov hmoov txhuas. Txiav txim tus nqi tshaj plaws -ib qho txiaj ntsig uas tshem tawm txhua daim tshev saum toj no.
Txoj cai H-beam sib npaug tag nrho rau qhov cuam tshuam rau txoj haujlwm kev sib txuas, txheej txheem tsim, pob nyiaj siv, thiab lub sijhawm xa khoom.
FAQ
Puas yog H-Beams haum rau Ntev Span Structures?
Lawv tuaj yeem ua tau, tab sis cov seem tseem yuav tsum tau ntsuas los ntawm qhov tseeb ncua sij hawm, thauj khoom, kev txhawb nqa, thiab txwv deflection. Tsis muaj ib ntu uas tsim nyog raws li "ntev-span" ntawm nws tus kheej.
Dab tsi yog H Beam Steel siv rau
H-beams feem ntau yog siv rau hauv cov ntawv thov uas muaj zog dabtsi yog khoov thiab nruj, xws li dav hlau hangars, warehouses, thiab lwm yam loj -span industrial vaj tse.
Qhov txawv ntawm H-Beam thiab kuv-Beam yog dab tsi?
Qhov sib txawv tseem ceeb yog tias, rau qhov hnyav tib yam, H-beam feem ntau muaj kev tiv thaiv ntau dua rau kev khoov. Qhov no ua rau H-beams zoo dua rau cov thawj thav duab hauv cov qauv loj -span, thaum kuv-beams feem ntau siv rau cov tswv cuab theem nrab.
