H Beam

H-beams muaj nyob rau hauv ntau yam ntawm cov specifications, categorized raws li nram no:

1.Los ntawm Flange Dav:

• Wide Flange (HW):Flange dav (B) ntau dua lossis sib npaug ntawm lub vev xaib qhov siab (H).

• Medium Flange (HM):Flange dav (B) yog kwv yees li qhov siab ntawm lub vev xaib (HH).

• Narrow Flange (HN):Flange dav (B) yog kwv yees li ib nrab ntawm lub vev xaib qhov siab (H).

2.Los ntawm Daim Ntawv Thov:

suav nrog H-beam kab, H- kab teeb kab,bearing pawg, thiab ntxiv -thick flange beams. Qee lub sij hawm, parallel - ceg channels thiab parallel -flange T- ntu kuj suav nrog hauv pawg no. Feem ntau, nqaim- hom flange yog siv raws li kab teeb, thaum dav - flange hom yog siv los ua kab.

3.Los ntawm txoj kev tsim khoom: Welded H-beamsthiabRolled H-beams.

4.Los ntawm Qhov Loj (Weight H):

Loj - loj:

H>700 hli

Nruab nrab- loj:

300mm Less dua los yog sib npaug H Less dua los yog sib npaug rau 700mm

Small -loj:

H<300mm

(Thaum kawg ntawm xyoo 1990, lub ntiaj teb loj tshaj plaws H-beam mus txog lub vev xaib qhov siab ntawm 1200mm thiab flange dav ntawm 530mm).

International Standards

Thoob ntiaj teb, H-beam khoom qauv muab faib ua ob lub tshuab:ImperialthiabMetric. Lub tebchaws United States thiab lub tebchaws United Kingdom feem ntau siv lub Imperial system, whereas Tuam Tshoj, Nyiv, Lub teb chaws Yelemees, thiab Russia siv lub Metric system. Txawm li cas los xij, qhov tshwj xeeb yog sawv cev los ntawm plaub qhov loj me:

Web qhov siab (h)

Flange Dav (b)

Web Thickness (d)

Thickness ntawm flange (t)

Thaum sawv cev txoj kev sib txawv los ntawm lub teb chaws, qhov tsim muaj ntau yam thiabqhov tolerancesnyob twj ywm zoo ib yam thoob ntiaj teb.

Hauv kev tsim kho thiab tshuab, H-beams thiab I-beams yog ob hom hlau uas"zoo li zoo sib xws tab sis tuaj yeem ua rau muaj kev cuam tshuam loj heev yog siv tsis raug."Txawm tias muaj kev paub txog engineers qee zaum tsis meej pem lawv qhov kev ua tau zoo thiab cov ntawv thov scenarios.

Niaj hnub no, peb muab ib qho kev ntsuam xyuas qhov tob ntawm "Steel Brothers" no nyob rau plaub qhov loj: qauv, kev ua tau zoo, tus nqi, thiab cov txheej txheem tsim khoom!

I. Hla-Sectional Shape

Kuv -Beam:

Tus ntoo khaub lig- seem zoo li tus cim Suav "工".

Sab sauv thiab qisflanges yog tapered(thicker ntawm lub hauv paus thiab thinner ntawm ntug) nrog txoj kab nqes ntawm kwv yees li 14%.

Nws nta atuab web, nqaim flanges, thiab cov npoo sib npaug ntawm cov ntsiab lus hloov pauv.

H-Beam:

Tus ntoo khaub lig-section ntau zoo ib yam li tsab ntawv Askiv "H".

Covflanges muaj cov tuab tuab thiab sib npaugrau ib leeg.

Qhov sib piv ntawm ntu qhov siab thiab flange dav yog qhov zoo- sib npaug, cov npoo yog square (txoj cai-angled), thiab tag nrho symmetry yog ntau dua.

II. Kev sib piv

CEEB TOOM:Kuv-beams siv raws li load- kab kabmob yog nquag buckling thiab instability.H-beams yog qhov tseeb "rov qab" ntawm cov tsev siab -nce.

III. Txheej txheem ntau lawm

Kuv -Beam:

Feem ntau tsim los ntawm covkub- dovtxheej txheem nyob rau hauv ib tug pass. Cov txheej txheem yog yooj yim thiab tus nqi kuj tsawg. Muaj tsawg zaus, kuv -beams yog fabricated los ntawm vuam.

H-Beam:

Feem ntau ua los ntawmkub- dov, txawm tias ib txhiaweldedlos ntawm peb daim hlau sib cais.

Cov txheej txheem kub - dov rau H- kab teeb yog qhov nyuaj dua thiab yuav tsum tau tshwj xeeb universal dov mills. Yog li ntawd, tus nqi tsim khoom yog kwv yees li20% -30% siab duatshaj qhov kuv-beams.

IV. Daim ntawv thov sib txawv

Kuv -Beam:

Feem ntau siv raws likab rov tav beam Cheebtsamnyob rau hauv steel qauv. Vim nws qhov cross me me -sectional dimensions, nws yog haum rau scenarios nrogme me spans thiab lub teeb loads.

H-Beam:

Dav siv raws liload-cov kab muaj kabnyob rau hauv steel qauv. Vim nws cov ntoo khaub lig loj dua -sectional qhov ntev thiab lub zog zoo dua, nws tau siv dav hauv cov xwm txheej nrogloj spans thiab hnyav load yuav tsum.

Lub thickened kuv -beam hloov H-beam?

Qhov tseeb:Lawv tus ntoo khaub lig- cov duab ntu thiab cov khoom siv tshuab yog qhov sib txawv. Txawm hais tias ib qho I-beam tuaj yeem ua qhov kev hloov pauv tsawg hauv cov xwm txheej tshwj xeeb, nws yogtsis yog qhov sib npaug hloovrau H-beam!

H-beams feem ntau yog siv raws li kab teeb thiab kab ke hauv kev lag luam thiab pej xeem cov qauv.

• Steel load-cov kabmob txhawb nqarau cov qauv kev lag luam.

• Steel pawg thiab shoring structuresrau underground engineering tej yaam num.

• Cov cuab yeej siv kho vaj tserau petrochemical, hluav taws xob, thiab hluav taws xob kev lag luam.

• Cov yam ntxwv ntawm cov khoomrau ntev -span steel choj.

• Ncej qauvrau shipbuilding thiab heavy machinery manufacturing.

• Chassis beams thiab bracketsrau tsheb ciav hlau, tsheb, thiab tsheb laij teb.

• Kev them nyiaj yug systemsrau qhov chaw nres nkoj conveyor siv thiab txoj kev loj guardrails / barriers.

Lub I-beam muaj qhov dav me me (ntev ntev) thiab qhov siab loj, uas tso cai rau nws los tiv thaiv cov rog hauv ib qho kev taw qhia xwb.

• Lub H-nqaj nta ib ntu sib sib zog nqus thiab tuab tuab, ua kom nws tiv taus quab yuam los ntawm ob qho kev qhia.

• Nrog rau kev txhim kho steel qauv vaj tse, kuv- kab teeb ib leeg tsis txaus. Txawm tias thickened I-beams yog nquag mus rau instability (buckling) thaum siv raws li load-cov kabmob kab.

• I-beams raug txwv tsis pub siv raws li cov kab hla hla, qhov H-beams yog tsim los siv raws li cov qauv thauj khoom-cov kab kabmob.

• H-beam yog ib qho kev lag luam steel nrog cov ntoo khaub lig zoo tshaj -sectional mechanical zog piv rau I-beam, muaj npe rau nws cov duab zoo li tsab ntawv Askiv "H." Cov flanges ntawm kub- dov H- kab teeb yog dav dua li ntawm I- kab teeb, muab ntau dua lateral tawv thiab siab dua dabtsi yog khoov. Raws li tib yam specifications, qhov theoretical qhov hnyav ntawm H-beam yog sib dua li ntawm I-beam.

• Kuv-beam flanges muaj qhov sib sib zog nqus-section (thicker ze ntawm lub vev xaib thiab nyias nyias ntawm ntug sab nrauv), thaum H-beam flanges muaj qhov sib xws -section (qhov tuab tas li).

• H yog lub ntsiab lus dav dav rau H-beams thiab feem ntau yog hais txog welded (fabricated) hom; HW, HM, thiab HN tshwj xeeb yog xa mus rau kub- dov H- kab teeb.

• HW qhia H-beams qhov siab thiab flange dav yog qhov tseem ceeb sib npaug. Lawv feem ntau yog siv los ua steel core kab hauv cov pob zeb ua vaj tse (RC) thav duab, tseem hu ua cov kab hlau khov. Hauv cov qauv hlau ntshiab, lawv tsuas yog siv rau txhua kab.

• HM qhia H-beams qhov siab -rau- dav piv yog kwv yees li 1.33 txog 1.75. Hauv cov qauv steel, lawv tau siv los ua steel ncej kab lossis raws li cov kab teeb tsa hauv cov qauv raug rau cov khoom siv dynamic, xws li cov khoom siv platforms.

• HN qhia H-beams qhov siab -rau-width ratio yog 2 lossis ntau dua. Lawv feem ntau yog siv rau kab teeb; qhov siv hluav taws xob ntawm I-beams yog sib npaug ntawm HN-hom H-beams.

Raws li ib qho ntawm cov coj h beam tuam ntxhab thiab cov muag khoom nyob rau hauv Suav teb, peb sov siab txais tos koj los yuav h beam hauv Tshuag ntawm no thiab tau txais cov qauv dawb los ntawm peb lub hoobkas. Tag nrho cov khoom customized yog nrog cov khoom zoo thiab tus nqi qis.
