Scaffolding tubes yog cov hlau yeeb nkab seem uas yog siv los tsim ib lub scaffolding, uas yog ib qho kev txhawb nqa uas tsim tawm sab nraud ntawm cov tsev thiab cov tsev uas tab tom tsim. Cov neeg ua haujlwm tuaj yeem nkag mus rau theem siab ntawm lub tsev lossis cov qauv los ntawm kev nce cov qauv ib ntus thiab sawv ntawm cov platforms. Scaffolding hlab tuaj nyob rau hauv ntau qhov ntev, tso cai rau cov qauv scaffolding kom haum rau ib txoj haujlwm tshwj xeeb. Couplers tuav lawv ua ke thiab tuaj yeem sib txawv ntawm qhov loj me thiab ua haujlwm nyob ntawm qhov xav tau daim ntawv thov.
Scaffolding raj tau muab faib ua peb hom: cov qauv, daim ntawv teev npe, thiab cov transoms. Cov kab ntsug scaffolding uas yuav txhawb nqa tag nrho cov qauv yog hu ua cov qauv. Txhawm rau muab kev txhawb nqa sab nraud, ledgers khiav kab rov tav, feem ntau ntawm cov qauv. Transoms yog cov hlua me me uas khiav perpendicular rau ledgers thiab siv los ntxiv kev ruaj ntseg rau cov qauv nrog rau qhov chaw rau cov platforms. Thaum cov qauv tiav lawm, cov khoom sib txuas txuas tag nrho cov kab sib txawv ntawm cov hlua scaffolding los tiv thaiv kev sib tw dhau los lossis txav mus los. Vim tias cov raj thiab cov txuas txuas yog modular, cov qauv ntawm ntau yam duab, qhov siab, qhov ntev, thiab qhov dav tuaj yeem tsim tau.
Scaffolding raj feem ntau yog ua los ntawm steel los yog txhuas. Cov raj steel hnyav dua, tab sis lawv kuj muaj zog heev. Txawm hais tias aluminium tubes yog qhov sib dua, lawv tsis tuaj yeem txhawb nqa qhov hnyav tib yam li cov raj hlau. Cov raj sib xyaw siv qee zaus, tab sis lawv kim dua thiab tsis siv ntau npaum li cov raj hlau. Scaffolding hlab yog yooj yim txiav mus rau ntev, thiab lawv feem ntau yog muag ntawm ib tug ntev ntev - feem ntau nyob ib ncig ntawm 20 ko taw (6.3 meters) - thiab ces txiav raws li. Qhov dav feem ntau yog tus qauv, thiab lub thickness ntawm phab ntsa tuaj yeem txiav txim siab npaum li cas qhov hnyav ntawm cov qauv tiav tuaj yeem txhawb nqa.
Cov raj hlau feem ntau yog galvanized. Qhov no txhais tau tias lawv yog zinc-coated, uas pab tiv thaiv xeb thiab corrosion tshwm sim los ntawm raug rau lub ntsiab. Aluminium raj feem ntau tsis tas yuav tsum tau galvanized vim tias txhuas yog xeb thiab corrosion resistant. Yog tias cov hlau tsis yog galvanized, nws feem ntau yog pleev xim los yog tshuaj kho kom tiv thaiv huab cua puas. Hlau khoov thaum muaj kev cuam tshuam, tab sis nws tuaj yeem yooj yim khoov rov qab rau hauv cov duab; aluminium yog nkig ntau dua thiab tsawg dua yuav khoov rov qab rau hauv cov duab tom qab muaj kev cuam tshuam.
