"Purlins tseem ceeb heev hauv kev tsim kho. Kuj tseem hu ua purlins, cov kab kab rov tav lub ru tsev no hla cov rafters lossis trusses. Lawv pab ua kom lub ru tsev ruaj khov, zoo li lub thav duab ntawm lub tsev, yog li txhawb cov rafters thiab cov ntaub ntawv vov tsev. Purrlin tau hloov zuj zus ntau zaus raws li kev txhim kho txuas ntxiv hauv cov ntaub ntawv tshawb fawb thiab kev tsim vaj tsev. Lub hauv paus purlins feem ntau txuas nrog cov qauv kab thiab kab teeb, uas coj cov khoom tseem ceeb- coj lub luag haujlwm thiab txhawb nqa cov ntaub ntawv vov tsev thiab lwm cov neeg txhawb nqa, lawv yog cov neeg ua haujlwm ntawm lub ru tsev ncej nruab nrab ntawm lub ntsiab purlins, theem nrab purlins tsim lub ru tsev muaj peev xwm. Meanwhile muab thaub qab rau cov ntaub ntawv vov tsev.
Txoj kev sib txuas purlin kuj tseem ceeb heev thiab yuav tsum ua raws li cov txheej txheem tsim nyog los xyuas kom meej qhov kev ruaj ntseg thiab kev nyab xeeb ntawm tag nrho lub tsev qauv. Piv txwv li, C purlins tuaj yeem txuas nrog siv vuam lossis bolting. Vuam yog muaj zog tab sis tuaj yeem nkag warp steel. Bolting pab hauv disassembly, tab sis nws lub zog qis xav tau kev ntsuas kom tsis txhob xoob. Nyob ntawm qhov xwm txheej tshwj xeeb, ntau yam kev sib txuas yuav tsum raug xaiv kom raug los lav tag nrho kev ruaj ntseg ntawm cov qauv. "
1/Purlins hauv Steel Structures
Hlau purlins yog tsim los ntawm kub- dov steel ntawv thiab tsimlos ntawm kev txias - dabtsi yog khoov. Lawv feem ntau yog siv nyob rau hauv ru tsev thiab phab ntsa systems nyob rau hauv steel lug, raws li zoo raws li nyob rau hauv machinery manufacturing. Lawv feem ntau yog C-zoo li tus thiab Z- zoo li tus, featuring nyias phab ntsa, tsis tshua muaj hnyav, zoo heev ntoo khaub lig-sectional zog, thiab cov khoom siv tau zoo. Nyob ntawm kev tsim kho, galvanizing tuaj yeem xaiv los txhim kho corrosion kuj. Purlins ntawm cov ntoo khaub lig sib txawv- cov duab ntu (xws li C-puab thiab Z- zoo li cov hlau) sib txawv hauv cov khoom siv kho tshuab thiab siv tau.
Hauv qee qhov loj - nplai steel- cov chaw tsim khoom lag luam, purlins ua los ntawm C- zoo li tus lossis Z- zoo li cov hlau yog siv dav. Lawv lub zog loj thiab tawv ua rau lawv zoo meej rau hnyav- thauj khoom, loj- ncua kev tsim kho. Z purlins, piv txwv li, muaj qhov tshwj xeeb Z-zoo li tus ntoo khaub lig- ntu uas muab kev thauj khoom zoo- muaj peev xwm thiab ruaj khov, yog li tiv thaiv sab nrauv. Tsis tas li ntawd, kev sib txuas ntawm ob lub flanges zoo heev ua rau kev tsim kho kom zoo dua los ntawm kev ua kom yooj yim rau kev sib txuas rau lwm cov purlins, txhawb nqa, thiab lwm yam.
2/ Qhov txawvBib nrab CPurlinthiab Z Purlin
Kev tsim vaj tsev niaj hnub nyob ntawm qhov tseem ceeb ntawm C purlins thiab Z purlins, uas muaj kev txhawb nqa rau phab ntsa thiab ru tsev. Cov ntawv thov feem ntau suav nrog kab, kab teeb, girders, keels, pem teb slabs, cov ntaub ntawv sib xyaw, thiab lwm yam.
1.1 Hla-sectional Shape
C purlin: Feem ntau ntawm 90-degree lub kaum sab xis, nyob rau sab xis ntawm lub hauv paus, lawv cov duab ntu ntu yog tsab ntawv C nrog cov qauv sib luag thiab tsim qauv qhib.
Z purlin: Feem ntau ntawm 60 thiab 75 degrees, nws tus ntoo khaub lig- seem zoo li tsab ntawv Z thiab muaj ob qhov txuas txuas ntawm cov ces kaum feem ntau tsawg dua 90 degrees. Nws yog qhov tsim nyog rau cov tsev ntev ntev.
1.2 Load-Bearing Capacity
C purlin: Rau cov tsev nrog luv luv, C purlins muab kev ua haujlwm ruaj khov nyob rau hauv cov khoom sib xws.
Z purlin: Cov khoom loj dua lossis ntev dua cov qauv siv tau zoo siv Z purlins. Lawv zoo torsional thiab dabtsi yog khoov kuj pab kom lawv nqa loj loads nrog tsawg dua qhov chaw.
1.3 Application Scenarios
C-Purlin:
-Kev siv lub teeb: Siv lub teeb yuag, yooj yim-rau- nruab cov qauv xws li lub ru tsev thiab phab ntsa hauv cov chaw tsim khoom me me, warehouses, chav tshuab, thiab cov ru tsev nyob.
-Small Span: Haum rau lub ru tsev nrog cov spans me.
-Tus nqi- Kev xaiv zoo: Zoo tagnrho rau cov haujlwm uas muaj peev nyiaj tsawg nrhiav kom txo cov khoom siv thiab cov nqi tsim kho.
Z purlin:
-Long-span vaj tse: Tsim nyog rau lub ru tsev thiab phab ntsa ntawm cov qauv loj xws li cov nroj tsuag, chaw ntau pob, thiab chaw ua yeeb yam.
-Cov qauv tsis yooj yim: Z purlins muab ntau- kev txhawb nqa kev taw qhia, muab kev txhawb nqa zoo ib yam hauv ntau cov lus qhia, txhim kho tag nrho kev ruaj ntseg thiab kev nyab xeeb ntawm cov qauv.
-High-xav tau tej yaam num: Tsim los rau cov tsev uas xav tau kev tiv thaiv huab cua huab cua, av qeeg, thiab lwm yam kev puas tsuaj ntuj tsim.
3/ CZ yog dab tsiPurlin Roll FormingMmob?
Covcz purlin yob txoj kev tshuabsiv galvanized lossis txias- dov steel sawb nrog lub thickness ntawm 1mm-4mm ua raw khoom. Los ntawm uncoiling, flattening, xuas nrig ntaus, sib sau, thiab txiav, nws tsis tu ncua ua CZ purlins. Nws kuj hloov tau yooj yim los ntawm C-puab rau Z-puab profiles. Kev ua haujlwm yooj yim, tsis tas yuav muaj kev cuam tshuam ntawm phau ntawv; kev ua haujlwm yooj yim pab kom hloov tau yooj yim.
