Vim li cas Framing Applications Xaiv Galvanized Square / Rectangular Tube
- Load- bearing efficiency ntawm seem kaw.Square thiab square hollow seem tiv thaiv dabtsi yog khoov thiab torsion zoo dua li qhib seem (lub kaum sab xis, raws) ntawm qhov hnyav zoo sib xws, vim hais tias qhov kaw qhov profile faib kev ntxhov siab nyob ib ncig ntawm tag nrho ib puag ncig es tsis yog tsom rau hauv ib lub vev xaib lossis flange. Rau cov kab ke thiab kab teeb uas nqa cov khoom sib xyaw ua ke - cua, daus, tuag load, thiab lateral bracing rog - qhov kev ua tau zoo no txhais ua cov qauv sib zog rau tib qhov kev ntsuas.
- Corrosion resistance qhov twg cov kev sib txuas raug nthuav tawm.Framing structures yog tag nrho ntawm kev sib txuas bolted, lub hauv paus daim hlau, thiab cov welded gussets - txhua qhov chaw uas ya raws thiab corrosion feem ntau pib ua ntej ntawm cov hlau tsis muaj kev tiv thaiv. Kub-dip zinc txheej tiv thaiv cov cheeb tsam no tib yam li nws tiv thaiv lub raj tiaj tus, thiab nws txoj kev txi tseem tiv thaiv lub hauv paus hlau txawm tias lub qhov ntsia hlau lossis qhov vuam tau cuam tshuam hauv zos.
- Tsis muaj repainting voj voog rau lub neej ntawm tus ncej.Cov qauv hlau uas yuav nyuaj lossis kim dua tom qab - hnub ci kev txhawb nqa, cov cuab yeej siv siab siab, lub tsev ua liaj ua teb thav duab - tau txais txiaj ntsig los ntawm txheej txheej uas tsis xav tau kev saib xyuas. Kub-dip galvanizing yog siv ib zaug, ntawm lub zeb los yog ib qho kev cog lus galvanizing, thiab feem ntau outlass lub tsev thawj lub voj voog kho tshiab loj.
- Dimensional sib xws rau bolted kev sib txuas.Vim hais tias framing raj feem ntau yog koom nrog cov phaj hauv paus, lub hau phaj, thiab cov bolted gusset kev sib txuas es tsis yog teb -welded pob qij txha nkaus xwb, nruj tswj ntawm sab nraud qhov ntev thiab squareness tseem ceeb ntawm no ntau dua li hauv lwm cov ntawv thov raj - ib lub raj uas me ntsis tawm ntawm cov square complicates phaj haum -txog tag nrho cov qauv.
Lub raj ua li cas
Lub hauv paus square / rectangular raj pib raws li ERW round yeeb nkab, tsim thiab welded los ntawm steel sawb, ces dhau los ntawm ib tug series ntawm txoj kev yob uas reshape lub puag ncig seem mus rau hauv ib tug square los yog rectangular profile thaum lub weld tseem nyob rau hauv los yog nyob ze ntawm lub forming kub. Qhov no ua rau lub kaum sab xis ntawm lub kaum sab xis thiab tsis txhob rov- cua sov lub raj sib cais rau shaping.
Tom qab tsim, txiav, thiab ib qho yuav tsum tau soj ntsuam weld, lub raj yog kub -dip galvanized tom qab tib lub pickle -flux-dip raws li siv rau puag ncig cov yeeb nkab: kua qaub ntxuav kom tshem tawm nplai, flux da dej, ces tag nrho immersion nyob rau hauv molten zinc nyob ib ncig ntawm 450 degree.
Cov qauv thiab Sizing rau kev siv tus qauv
- ASTM A500 1- tus qauv tseem ceeb hauv Teb Chaws Asmeskas rau qhov txias txias - tsim welded square thiab cov duab plaub lub raj, txhais Qib A, B, thiab C los ntawm kev tawm los thiab lub zog tensile.
- ASTM A123/A123M- tswj kub-dip galvanized txheej yuav tsum tau siv rau lub raj A500.
- TS EN 10219- tus qauv European rau txias- tsim welded structural hollow seem, feem ntau ua ke nrog EN ISO 1461 rau kub -dip txheej yuav tsum.
Framing tej yaam num feem ntau qhia txog qib B (46 ksi yam tsawg kawg nkaus tawm los) raws li lub hauv paus rau kev ua hauj lwm structural, tsiv mus rau Qib C (50 ksi) qhov twg siab load peev xwm yuav tsum tsis txhob nce seem loj. Qhov ntau thiab tsawg ntawm cov qauv khiav los ntawm 50 × 50 mm txog 200 × 200 mm square, thiab los ntawm 60 × 40 mm mus txog 250 × 150 mm duab plaub, nyob rau hauv phab ntsa thicknesses los ntawm roughly 2.5 hli mus rau 8 mm nyob ntawm qhov ntev thiab load.
Cov lus nug nquag nug (FAQ)
Q: Puas yog galvanized structural raj muaj zog li dub (uncoated) raj ntawm tib qib?
A: Yog - kub-dip galvanizing tsis txo cov hlau tawm los yog lub zog tensile rau cov qauv phab ntsa thicknesses. Cov khoom siv kho tshuab tau teeb tsa los ntawm qib steel (A500 Qib B lossis C, piv txwv li) ua ntej galvanizing, thiab txheej txheem txheej txheem ntawm qhov kub da dej tsis muaj txiaj ntsig hloov cov khoom no hauv cov qauv txheej txheem.
Q: galvanized square raj puas tuaj yeem welded rau ntawm qhov chaw yam tsis muaj kev tiv thaiv corrosion?
A: Nws tuaj yeem welded, tab sis vuam kub hnyiab tawm ntawm zinc txheej hauv tshav kub - cuam tshuam. Kev coj ua qauv yog txhawm rau txhawm lossis ntxuav qhov chaw vuam tom qab vuam thiab siv zinc- nplua nuj txias galvanizing compound los kho cov kev tiv thaiv corrosion hauv zos - qhov no yog ib feem ntawm kev txhim kho cov qauv galvanized, tsis yog qhov tsis xws ntawm cov khoom.
Q: Qhov txawv ntawm A500 thiab EN 10219 raj yog dab tsi, thiab nws puas tseem ceeb rau qhov kuv xaj?
A: Ob leeg yog txias-tsim welded structural hollow seem qauv, tab sis lawv nyob nraum calibrated rau txawv regional qib thiab kam rau ua. Yog tias koj qhov kev tsim vaj tsev tau ua tiav rau US cov lej, qhia A500; yog tias nws tau ua tiav rau Eurocode, qhia EN 10219 - cov qauv sib xyaw ntawm ib qhov project tuaj yeem tsim kev tsis sib haum xeeb ntawm qhov muaj txiaj ntsig kev ntxhov siab txawm tias lub cev lub cev zoo ib yam.
Q: Puas yog kub -dip galvanized raj xav tau cov txheej txheem ntxiv rau cov ntug dej hiav txwv lossis thaj chaw muaj kev lag luam?
A: Nyob rau hauv ib puag ncig hnyav dua - ntug hiav txwv ntsev raug los yog muaj huab cua nrog cov sulfur dioxide - duplex system (cov xim pleev xim los yog cov hmoov pleev xim rau saum qhov kub- dip zinc) feem ntau tau teev tseg kom ntev kev pab cuam lub neej tshaj li zinc ib leeg yuav ua tiav. Nug txog koj qhov chaw ib puag ncig ua ntej defaulting rau zinc- tsuas yog txheej txheej ntawm cov haujlwm hauv cov xwm txheej no.
