Steel paub txog kev muab cov qauv thiab lub zog zoo li tsis muaj lwm yam thaum nws los txog rau kev tsim kho. Lub durability thiab lub zog uas cov hlau muab tsis yog piv rau cov ntoo lossis pob zeb. Hlau feem ntau yog cov khoom siv rau kev tsim kho, thiab tib neeg nyiam nws rau nws ntau yam zoo.
Cov tsev hlau kuj feem ntau tsim nrog cov qauv sib txawv, piv txwv li qhib ncua, modular thiab ib txoj kab nqes. Vim tias cov hlau yog yooj yim dua thiab siv sij hawm tsawg dua los tsim, nrog rau ntau lwm yam uas tau ua pov thawj tias muaj txiaj ntsig zoo, steel tau dhau los ua txoj hauv kev zoo tshaj plaws ntawm kev tsim vaj tsev niaj hnub no.
Nrog steel peb tuaj yeem tsim cov qauv zoo li tsis muaj lwm yam khoom siv thaum nws los txog rau kev tsim kho. Tsis muaj lwm yam khoom muaj lub zog thiab kav ntev ntawm cov hlau. Cov qauv hlau tsis ntseeg tau dhau los ua qhov kev xaiv zoo tshaj plaws rau kev tsim kho vim muaj ntau yam zoo uas nws nthuav tawm. Cov vaj tse uas tsim los ntawm cov hlau yuav tsum muaj ntau yam kev tsim qauv. Tsis tas li ntawd, lub tsev nrog cov hlau yuav siv sij hawm tsawg dua, ua rau nws yog txoj hauv kev zoo tshaj plaws los tsim cov qauv.
Qee yam ntawm ntau hom hlau thiab cov txiaj ntsig nws muaj peev xwm muab tau raws li hauv qab no. koj.
STRUCTURAL STEEL
Ua ntej ntawm tag nrho cov, nws yog ib qho tseem ceeb kom paub tias cov qauv steel yog dab tsi thiab nws yog tsim li cas. Cov qauv steel duab yog tsim los ntawm cov hlau no, uas muaj cov qauv sib luag. Tab sis, nyob rau tib lub sijhawm, nws ua raws li cov qauv kev cai hais txog cov khoom siv kho tshuab thiab tshuaj lom neeg muaj pes tsawg leeg.
Cov qauv hlau tuaj nyob rau hauv ntau hom xws li L-beam, Z-form, HSS-form, L-form (lub kaum), cov qauv channel (C-beam, hla ntu), T-form, rail profile, bar, phaj thiab qhib beam ua los ntawm sawb hlau.
Standard structural steel sib txawv nyob rau hauv ntau lub teb chaws nrog txawv specifications. Piv txwv li, European I-beam yog Euronorm 19-57, thaum cov qauv hlau hauv Teb Chaws Asmeskas tuaj hauv cov pa roj carbon, tsis tshua muaj hlau alloy, high-corrosion-resistant low-alloy, hardened alloy thiab tempering, thiab lwm yam.
Cov qauv hlau yog ntau yam, muaj zog thiab ruaj khov, yog li nws tsis yog qhov xav tsis thoob tias nws tuaj yeem hloov mus rau yuav luag txhua yam nyob ntawm qhov kev tsim kho uas tau ua tiav; nws tuaj yeem tsim yuav luag tam sim ntawd lub sijhawm nws tau txais ntawm qhov chaw.
Cov qauv hlau yog hluav taws kub resistant, tab sis txoj kev tiv thaiv hluav taws yuav tsum tau muab tso rau hauv qhov chaw yog tias muaj lub caij nyoog uas nws yuav ua kom sov mus txog qhov chaw uas nws pib poob nws cov kav ntev thiab lub zog.
Corrosion yuav tsum tau zam thaum nws los txog rau cov qauv hlau, tab sis cov tsev siab tau paub tias tiv taus ntau yam kev nyuaj siab thaum ua nrog cov qauv hlau.
Kev tsim kho steel tau dhau los ua neeg nyiam thoob plaws ntiaj teb, thiab txhua cheeb tsam tau txais txiaj ntsig los ntawm cov hlau ntau xyoo.
Ntau qhov zoo tshaj plaws architectural xav tau tsim nrog hlau, yog nws cov qauv, carbon los yog rebar, xws li lub teb chaws Ottoman State Tsev thiab Sydney Harbor Choj. Thiab dab tsi yog qhov tseem ceeb tshaj, kev siv cov hlau yog ib puag ncig zoo dua li lwm hom kev tsim kho, thiab tsuas yog rau qhov no nws yog qhov kev nyiam ntau dua.
Xav txog qhov nrawm ntawm kev tsim kho zoo kawg nkaus, steel tau ua pov thawj tias muaj txiaj ntsig zoo. Nrog rau kev siv hlau ntau ntxiv hauv kev tsim kho kev lag luam, tsis muaj qhov tsis ntseeg tias nws yuav siv tag nrho kev tsim kho yav tom ntej.
Hauv qab no yog ntau hom qauv hlau thiab lawv siv hauv kev tsim kho.
PARALLEL FLANGED CHANNELS
Cov kab teeb ci no yog U-puab nrog cov ces kaum sab xis, zoo li cov duab ntawm cov staple. Lawv muaj nyob rau hauv ntau qhov ntau thiab tsawg; Txawm li cas los xij, ob sab yog ib txwm ntev thiab sib npaug rau ib leeg. Lawv kuj muaj lub zog-rau-hnyav piv thiab muaj kev siv zoo sib xws li lub kaum sab xis.
TAPERED FLANGE BEAMS
Tapered Flange Beams yog I-shaped thiab kuj muaj nyob rau hauv ntau qhov ntau thiab tsawg. Hauv kev tsim kho, lawv feem ntau yog siv los ua ntu ntu rau kab teeb. Txawm hais tias lawv muaj qhov sib piv tshwj xeeb, nws tsis yog feem ntau pom zoo thaum muaj qhov siab ntawm qhov ntev, vim lawv tsis tiv taus kev sib tw (twisting).
UNIVERSAL BEAM
Universal beams, tseem hu ua I- lossis H-beams, zoo li lawv lub npe: "Kuv" thaum sawv ntsug thiab "H" ntawm lawv sab. Universal beams feem ntau yog ua los ntawm cov qauv hlau thiab siv rau hauv kev tsim kho thiab kev tsim vaj tsev, ntawm lwm yam kev lag luam.
UNIVERSAL COLUMN
Universal beams kuj tau siv dav rau kev tsim qauv. Lawv zoo li kab teeb thiab feem ntau hu ua I- lossis H-beams, txawm tias tag nrho peb ntu yog tib qhov ntev. Raws li lub npe qhia, lawv tsuas yog siv rau cov ncej, thiab lawv muaj peev xwm ua tau zoo tshaj plaws.
QHOV TSEEB
Lub luj tshib cov qauv profiles tuaj yeem zoo ib yam lossis tsis sib npaug. Lawv ob leeg muaj lub kaum sab xis; Txawm li cas los xij, cov seem tsis sib xws muaj qhov sib txawv ntawm qhov sib txawv, ua rau lawv L-puab, hom ntu no muaj zog ntau dua (txog li 20 feem pua) thiab muaj zog dua qhov hnyav dua. Lub kaum sab xis yog siv nyob rau hauv kev tsim kho vaj tse, infrastructure, mining, thiab tsheb thauj mus los. Tsis tas li ntawd, lawv muaj nyob rau hauv ntau qhov ntev thiab qhov ntau thiab tsawg.
CIRCULAR HOLLOW SECTIONS
Circular hollow seem tshwm sim raws li hollow tubular hla ntu thiab muaj zog torsional ntau dua li tapered flanged beams. Qhov ceev ntawm cov phab ntsa yog sib xws thoob plaws hauv lub voj voog, ua rau cov nqaj no zoo tagnrho rau kev siv hauv ntau qhov kev thauj khoom.
RECTANGULAR HOLLOW ntu
Cov yam ntxwv ntawm cov hlau no muaj ntau yam zoo li lub voj voos kheej kheej, tab sis muaj cov kab sib dhos. Lawv nrov heev nyob rau hauv ntau yam kev siv tshuab thiab steel siv. Lawv qhov chaw tiaj tus ua rau lawv zoo tagnrho rau kev siv hlau txuas thiab fabrication.
SQUARE HOLLOW PROFILES
Zoo li lawv cov hollow seem counterparts (tshwj tsis yog nrog cov square cross section), lawv tau siv hauv cov ntawv me me xws li kab lossis ncej. Txawm li cas los xij, lawv tsis haum rau cov kab teeb, vim lawv cov duab yog qhov nyuaj rau bolt rau lwm hom duab. Lawv kuj hu ua "box sections".
QHOV TSEEB
Nws yog tejzaum nws muaj ntau hom steel seem, raws li nws yuav tsum tau kho rau lwm seem. Qee zaum, lawv tuaj yeem txuas mus rau lwm ntu raws li cov cuab yeej txhawb nqa. Lawv kuj tseem hu ua "phaj" (piv txwv li, daim hlau checkerboard).
