Universal Beam

Paub nyob rau hauv teb chaws Australia li universal beams (UB) thiab universal kem (UC) tab sis kuj feem ntau hu ua I beams thiab H beams, cov no muaj npe tom qab kuv thiab H-zoo li tus tsos ntawm lawv tus ntoo khaub lig-section.

Ntu ntu nruab nrab ntawm lub nqaj yog hu ua 'web' thiab kab rov tav cov khoom hu ua 'flanges'. Cov kab teeb no yog tsim los txhawb nqa ntau qhov hnyav hauv ib qho kev coj. UBs siv nyob rau hauv cov plag tsev yuav txhawb nqa ntau zog vertically dua li tus qauv square beam, tab sis tsis muaj zog tiv thaiv kab rov tav txav thiab tsis hnov ​​​​zoo rau twisting. Lawv yog siv los ua ib feem hauv pem teb thav duab thiab siv tau nrog lwm cov kab thiab joists qhov twg ntxiv load- bearing peev yuav tsum tau.

Ntau qhov ntev
Ib qho ntawm qhov zoo tshaj plaws ntawm universal beams yog lawv versatility nyob rau hauv cov nqe lus ntawm qhov ntev thiab qhov ntau thiab tsawg. Muaj tseeb rau lawv lub npe, universal beams muaj nyob rau hauv ntau yam ntawm qhov hnyav, seem qhov tob, flange widths, thiab web thicknesses. Qhov ntau yam no tso cai rau kev kho kom haum raws li cov kev cai tshwj xeeb ntawm cov haujlwm sib txawv. Txawm hais tias nws yog ib lub tsev me me lossis ib qho chaw ua lag luam loj, muaj qhov I- nqaj loj uas haum rau txhua daim ntawv thov.

Txawm Nyuaj Tshaj
Lawv tau tsim los tswj cov khoom sib xws thoob plaws lub nqaj ntev, nrog qhov siab tshaj plaws deflection ntog ntawm qhov nruab nrab ntawm kab teeb. Qhov no ua rau kom qhov nro ntawm ob sab ntawm lub nqaj. Nrog rau qhov hnyav thov ntawm flange, tag nrho cov huab hwm coj tau faib sib npaug, ua rau muaj kev ntxhov siab tsawg dhau los ntawm lub vev xaib.

Dais siab Loads
Kev tsim cov kab teeb ua rau lawv muaj peev xwm khoov, tsis yog buckling, nyob rau hauv kev ntxhov siab. Hlau universal beams tuaj yeem tiv taus cov khoom loj loj. Lub zog ntawm cov hlau hauv I-beam zoo kuj tuaj yeem pab txo qhov kev xav tau ntawm ntau lwm cov qauv kev txhawb nqa, uas tuaj yeem pab txuag sijhawm hauv kev tsim kho.

Pab hauv Kev Cai Steel Fabrication
Universal steel beams muaj ntau yam thiab tuaj yeem siv rau hauv ntau yam kev tsim kho steel. Steel fabrication suav nrog kev txiav, khoov, thiab shaping ntawm steel, thiab steel beam fabrication yog ib qho ntawm cov txheej txheem ua tau zoo tshaj plaws rau kev ua tiav cov lus txib thiab ua tau raws li lub sijhawm kawg ntawm qhov project. Nws yooj yim dua los siv kuv cov kab teeb thaum lub sij hawm kev cai structural steel fabrication thiab vuam txheej txheem rau txhua hom kev tsim kho.

Recyclable Thiab Nqi -Yuav ua tau zoo
Cov khoom siv hlau tuaj yeem siv tau ntau zaus. Qhov zoo tshaj plaws yog tias lawv lub zog tsis muaj kev cuam tshuam ntev dua lawv siv. Recycling structural steel kuj tseem tuaj yeem pab txo cov nqi, txuag cov nqi tsim khoom, khoom siv, sijhawm thiab lub zog.

Txawm Nyuaj Tshaj
Universal beams yog engineered los daws cov teeb meem loads zoo. Kev tsim ntawm cov kab teeb no ua kom ntseeg tau tias qhov siab tshaj plaws deflection tshwm sim ntawm qhov nruab nrab ntawm kab teeb, uas ua rau muaj qhov hnyav hnyav ntawm ob sab. Los ntawm qhov sib npaug ntawm qhov hnyav, universal beams txo qhov kev ntxhov siab ntawm lub vev xaib thiab txhim kho tag nrho cov qauv kev ruaj ntseg.

Kev tsim kho
Universal Beams yog siv txhua lub sijhawm hauv kev tsim kho. Lawv tau siv rau hauv tshiab- tsim cov khoom uas cov qauv hlau txhawb nqa lub tsev tshiab, lossis thaum kho dua tshiab uas lub tsev uas twb muaj lawm raug hloov kho lossis txuas ntxiv. Lawv kuj tseem siv tau thaum tshem cov phab ntsa sab hauv. Yog tias phab ntsa yuav raug tshem tawm yog load-cov kabmob, yuav tsum muaj lub nqaj los hloov qhov kev txhawb nqa.

Kev thauj mus los
Nyob ib ncig ntawm 16% ntawm cov hlau uas tsim tawm thoob ntiaj teb yog siv hauv kev lag luam thauj, txawm tias nyob hauv tsheb, tsheb ciav hlau, nkoj thauj khoom ntim khoom, lossis dav hlau. Nws kuj tseem siv rau hauv kev thauj mus los xws li txoj kev, txuas hniav, tunnels, thiab kev tsheb ciav hlau thiab cov tsev loj xws li chaw nres nkoj, tshav dav hlau, thiab tsheb ciav hlau thiab chaw nres tsheb. Cov qauv hlau yog ib qho kev xaiv nrov vim nws elasticity, tensile zog, nqi -effectiveness, thiab malleability. Hauv tsheb, nws tau siv ntau lub ntsiab lus sab hauv, nrog rau kev tiv thaiv lub cav.

Cov choj
Cov kab hluav taws xob steel yog qhov tseem ceeb tshaj plaws thaum tsim cov choj vim lawv lub zog siab - tawm los. Cov qauv hlau los ntawm qee qib, thiab cov no yog siv rau kev tsim tshwj xeeb raws li txhua qib steel muaj qhov sib txawv, lub zog, shear theem, thiab compression. Dab tsi ntxiv, cov qauv hlau muaj zog thiab ruaj khov txaus los pab txhawb cov kev thauj khoom hnyav tshwj xeeb yuav tsum tuav.

Kev tsim khoom
Hlau yog siv hauv kev tsim khoom txhua lub sijhawm. Feem ntau ntawm cov khoom uas peb siv txhua hnub yog tsim los ntawm, los yog nrog, steel. Cov xov tooj ntawm tes, tsheb, tub yees, cov cuab yeej thiab tshuab, kev tsim kho thiab cov khoom siv ua liaj ua teb yog txhua yam ua los ntawm cov hlau. Txawm tias cov yas los yog iav fwj yog tsim los siv cov cuab yeej steel.

Art
Ntxiv nrog rau lawv cov qauv siv, universal beams kuj tau siv hauv kev kos duab thiab kho kom zoo nkauj. Lawv tuaj yeem siv los ua cov khoom zoo nkauj hauv tsev facades lossis ua duab puab hauv cov chaw pej xeem. Cov kab huv si thiab niaj hnub zoo nkauj ntawm cov kab teeb ua rau lawv muaj kev xaiv nrov rau kev tsim qauv.

Lawv Ua Li Cas
Cov kab teeb steel no xav tau cov txheej txheem tsim khoom uas muaj xws li milling lossis dov. Vim nws cov flanges tapered, kuv-beams feem ntau tsis ncaj tshaj H-beams.
H-beams, lub sijhawm no, yog ua los ntawm cov hlau dov thiab xav tau cov hlau yuav tsum tau welded ua ke. Cov flanges yog welded rau lub vev xaib los tsim nws cov duab H.

Beam Thickness
Kuv-beam webs yog nyias dua H-beam webs, uas txhais tau tias lawv tsis tuaj yeem tuav tau ntau npaum li qhov hnyav tab sis feem ntau sib dua. Qhov no ua rau kuv -beams haum rau cov haujlwm me me xws li cov tsev nyob, hos H-beams yog qhov zoo tagnrho rau cov qauv loj thiab siab dua li cov choj. H-beam flanges kuj dav dua, ntev dua, thiab hnyav dua li kuv-beams.

Beam Hla-sections
Tus ntoo khaub lig-section ntawm H-beam muaj zog ntau dua rau ib cheeb tsam ntawm I-beam. Qhov no ua rau H-beam tag nrho cov nqaj muaj zog nrog lub zog tsim nyog-rau- qhov hnyav piv. Raws li H-beams muaj thaj chaw loj, lawv zoo rau kev nqa hnyav.
Kuv-beams, ntawm qhov tod tes, muaj hla- ntu uas siab tshaj qhov dav ntawm lawv cov flanges. Qhov no ua rau cov kab hlau hlau zoo tshaj plaws tiv thaiv hauv zos buckling, qhov twg ib tus neeg qhov chaw thiab phaj cov ntsiab lus ntawm cov nqaj raug muab tso rau hauv siab heev.

Beam Qhov siab thiab qhov hnyav
I-beams yog sib dua thiab nyias dua H- kab teeb, thiab tsuas yog ncua ntawm 33 mus rau 100 ko taw vim lawv cov duab nyuaj. H-beams tuaj yeem ncav cuag 300 ko taw, ua rau lawv qhov kev xaiv pom tseeb rau cov qauv siab heev. Txawm li cas los xij, vim tias I-beams yog qhov sib sib zog nqus, lawv tsim nyog rau qhov luv luv thiab cov haujlwm uas yuav tsum muaj qhov hnyav dua.

Beam Resistance tiv thaiv Loads
Ob kab teeb muaj lub zog txaus los tiv thaiv ncaj qha thiab tensile loads. Txawm li cas los xij, H-beams yog qhov zoo dua ntawm kev tiv thaiv cov khoom sib tw vim tias lawv cov ntoo khaub lig- ntu loj dua thiab dav dua. Xws li, torsional deformation tsis tshua muaj tshwm sim thaum siv H-beams.

Beam siv tau rau hauv cov qauv
I-beams zoo dua li kev txhawb nqa ncej thiab kab, feem ntau yog siv rau elevators, trailers, tsev thiab cov vaj tse steel. H-beams, lub sijhawm no, tiv thaiv compression thiab nro thiab siv los txhawb nqa ntsug xws li girders, thiab cables.
