Nyeem ib Hollow Section Specification kom raug
Daim duab kos uas tsuas yog hais tias "HSS kem" yog cov ntaub ntawv tsis tiav rau tus neeg yuav khoom. Ib qho kev yuav khoom ua haujlwm tau zoo xav tau plaub yam uas raug kaw:
- Cov khoom siv tswj hwm tus qauv- qhov no kho cov chemistry, cov cuab yeej cuab tam yam tsawg kawg nkaus, thiab kev sim ntsuas lub raj tau raug tsim tawm thiab raug lees paub. North American ua haujlwm feem ntau taw qhia rau ASTM A500; Kev ua haujlwm nyob sab Europe feem ntau taw qhia rau EN 10210 (kub-tiav) lossis EN 10219 (txias- tsim); Lwm thaj chaw muaj lawv tus kheej sib npaug xws li GB / T 6728 hauv Suav teb lossis AS / NZS 1163 hauv Australia thiab New Zealand.
- Qib hauv tus qauv ntawd- vim hais tias ib qho qauv feem ntau suav nrog tsev neeg ntawm qib siab thiab tawv, thiab hloov ib qib rau lwm qhov hloov pauv qhov tseeb ntawm cov tswv cuab tuaj yeem nqa tau.
- Lub nominal sab nraud qhov ntev thiab phab ntsa thickness- ncaj nraim, tab sis tsim nyog ob npaug - tshuaj xyuas qhov loj me ntawm ib lub zeb los yog tus xa khoom tiag tiag cov khoom lag luam tawm tsam qhov yuav tsum tau ua haujlwm tshwj xeeb.
- Qhov kawg- liab qab zeb tiav, primed, pleev xim rau, los yog galvanized, vim qhov no cuam tshuam rau ob qho tib si dab tsi tshwm sim ntawm lub tsheb thauj khoom thiab yuav ua li cas cov khoom yuav tsum tau ua thaum nws nyob rau ntawm qhov chaw.
Nco ib qho ntawm plaub thiab "sib npaug" cov khoom siv tawm tsam qhov tsis tiav spec tuaj yeem ua ntsiag to tsis ua raws li qhov kev suav ntawm cov qauv xav tau.
Xaiv Ntawm SHS, RHS, thiab CHS Profiles
Nojsquare hollow seem (SHS)ua ntej. Nws plaub lub ntsej muag tiaj tus zoo ib yam muab cov neeg tsim khoom ua kom dej ntws mus rau thaj av gusset daim hlau, lub hauv paus daim hlau, thiab cov thav duab perpendicular yam tsis muaj kev cuam tshuam los yog kev daws teeb meem, uas yog ib feem loj ntawm vim li cas nws dominates raws li ib qho kev xaiv hauv qis - nce ua hauj lwm thiab tshwm sim ntau zaus raws li truss chord khoom qhov twg cov tswv cuab xav tau kev sib npaug bending kuj tsis hais txog kev taw qhia.
Rectangular hollow seem (RHS), ntawm qhov sib txawv, yog tiag tiag txog kev muab tus tsim lub pob qhov rooj tig. Vim tias ob lub axes muaj qhov sib txawv ntawm qhov sib txawv, tus kws tshaj lij tuaj yeem tig cov tswvcuab kom nws cov axis tawv kab nrog txhua qhov chaw uas cov load tiag tiag xav mus - uas yog vim li cas RHS qhia tau zoo ib yam li cov kab hauv pem teb thiab lub ru tsev purlin cov ntaub ntawv, qhov twg bending yog dhau ib qho - kev taw qhia pib nrog.
Ces muajCircular hollow seem (CHS). Round geometry kis tau cov ntaub ntawv zoo li ua tau nyob ib ncig ntawm lub axis rau cov tswv cuab nyob rau hauv axial load los yog twist, thiab nws tshwm sim kom huv si ua nws - uas yog vim li cas koj thiaj li yuav pom CHS tau teev tseg rau kis kab, tuav, thiab ib tug qauv qhov twg cua - los yog seismic - induced torsion case drives.
Qhov twg tus qauv tiag Diverge
Nws yog kev ntxias los kho "cov qauv hollow seem" ua ib qho khoom lag luam thoob ntiaj teb, tab sis cov qauv hauv qab nws tau sau nws tus kheej thiab tsis ua kom zoo.
ASTM A500 1(tus qauv feem ntau North American structural drawings reference) teev nws cov khoom uas yuav tsum tau nyob ib ncig ntawm Qib B / Qib C lub zog sib cais, nrog Qib B - 46,000 psi yam tsawg kawg nkaus tawm los rau cov seem - npog cov feem ntau ntawm cov tsev ua haujlwm zoo tib yam thiab Qib C tshwj tseg rau cov haujlwm uas xav tau cov npoo ntxiv.
TS EN 10219thiabTS EN 10210, qhov txias-tsim thiab kub- ua tiav European cov neeg sib tw, teeb tsa lub zog nyob ib puag ncig S235 / S275 / S355 qib tsev neeg hloov pauv, nrog rau qhov ntxiv toughness suffix (JR, J0, J2, thiab lwm yam) uas qhia tus neeg yuav khoom raws nraim qhov cuam tshuam lub zog ntawm cov hlau tau lees paub los tuav ntawm qhov ntsuas qhov ntsuas ntawm qhov ntsuas qhov ntsuas ntawm AST - txoj kev.
Tsis yog qhov no txhais tau hais tias ib qho system "zoo dua" - nws txhais tau hais tias tus neeg yuav khoom thoob ntiaj teb, lossis sib piv cov lus los ntawm cov neeg muag khoom ua haujlwm rau cov qauv sib txawv, xav tau los sib piv cov lej ntawm cov cuab yeej cuab tam tiag tiag es tsis xav tias cov npe qib txhais ncaj qha hla ciam teb.
Tej yam kev siv hauv kev tsim vaj tsev
Zinc tiv thaiv steel ob txoj kev: nws ua raws li lub cev barrier, thiab - tseem ceeb tshaj - nws ua raws li ib tug sacrificial anode, corroding nyiam los tiv thaiv tej me me ntawm cov hlau raug (ntawm ib tug txiav ntug los yog me me txheej puas, piv txwv li) los ntawm galvanic ua. Kev pab cuam lub neej nyob ntawm qhov hnyav ntawm atmospheric exposure qeb:
- Nyob deb nroog / teeb pom kev lag luam: coatings feem ntau kav ntau xyoo lawm ua ntej yuav tsum tau saib xyuas thawj zaug
- Suburban / nruab nrab industrial: me ntsis luv dua, tab sis feem ntau yog ntau- xyoo caum kev pab cuam lub neej
- Marine / ntug hiav txwv dej los yog hnyav industrial cua: corrosion tus nqi ntawm zinc yog sai dua, yog li cia siab tias yuav luv dua, txawm tias tseem muaj ntau, lub sijhawm ua haujlwm ua ntej kov- nce lossis rov ua dua yog lav
Lub koom haum American Galvanizers thiab cov koom haum sib piv thoob ntiaj teb luam tawm cov ntaub ntawv zinc corrosion los ntawm thaj chaw raug yog tias koj xav ua qauv kev pab cuam lub neej rau ib qhov chaw tshwj xeeb.
FAQ
Q: Dab tsi yog qhov txawv ntawm cov qauv hollow seem thiab tus qauv tshuab lossis yeeb nkab- qib raj?
A: Structural hollow seem yog tsim thiab ntawv pov thawj rau tus qauv tsim qauv (xws liASTM A500 1los yogTS EN 10219) nrog guaranteed yam tsawg kawg nkaus tawm los thiab tensile lub zog haum rau load- bearing tsim, nrog rau nruj nreem seem thiab kev soj ntsuam tswj. Mechanical lossis yeeb nkab- qib raj yuav zoo ib yam tab sis feem ntau tsis tau lees paub rau cov txheej txheem cov cuab yeej cuab tam thiab yuav tsum tsis txhob hloov mus rau hauv daim ntawv thov yam tsis tau txheeb xyuas nws qhov tseeb.
Q: Puas yog square, rectangular, lossis round hollow seem muaj zog rau lub tsev kem?
A: "Muaj zog" nyob ntawm hom tsis ua hauj lwm raug kuaj xyuas - puag ncig thiab square seem muaj qhov sib npaug ntawm lub vojvoog ntawm gyration nyob rau hauv tag nrho cov lus qhia, uas ua tau zoo rau txhua kab uas tsis muaj kev taw qhia kom meej meej, thaum cov duab plaub tuaj yeem ua tau zoo dua qhov kev thauj khoom feem ntau yog ib qho - kev taw qhia thiab tuaj yeem tig mus rau seem axis. Qhov kev xaiv zoo yog los ntawm kev suav cov qauv tshwj xeeb, tsis yog txoj cai dav dav ntawm tus ntiv tes xoo.
Q: Cov txheej txheem hollow seem puas tuaj yeem sau nrog pob zeb kom muaj peev xwm ntxiv?
A: Yog - pob zeb-cov kab hauv hollow seem yog ib qhov dej- tsim cov txheej txheem sib xyaw ua ke, qhov twg cov yeeb nkab steel confines lub pob zeb tseem ceeb (ua kom nws muaj zog compressive) thaum lub pob zeb ua kom lub raj phab ntsa tiv thaiv hauv zos buckling. Qhov no feem ntau yog siv qhov muaj peev xwm ntau dua axial lossis txhim kho qhov hluav taws kub xav tau nyob rau hauv ib qho kev txwv kab hneev taw.
Q: Puas yog cov qauv hollow seem yuav tsum tau galvanized rau kev tsim kho lub tsev?
A: Tsuas yog qhov uas daim ntawv thov xav tau nws - sab hauv, huab cua- tswj cov qauv hlau feem ntau yog sab laug nrog lub zeb lossis khw- primed tiav, thaum sab nrauv, hauv qab - qib, lossis siab - cov av noo feem ntau hu rau kub dip galvanizing lossis cov txheej txheem sib npaug. Qhov no yuav tsum tau teev tseg raws li qhov project cov xwm txheej raug, tsis yog los ntawm lub neej ntawd nyob rau hauv ob qho kev taw qhia.
