ru tsev hlau yog cov nplooj ntawv uas yog ua los ntawm cov khoom siv galvanized nrog cov txheej txheem polymer thiab pleev xim rau ntau yam xim. Txhawm rau xyaum cov vuas thaum lub sijhawm tsim khoom, tus qauv yog siv cov cuab yeej tshwj xeeb, uas tso cai rau lub ru tsev ntawm lub tsev kom zoo nkauj zoo nkauj.
Nws yuav tsum raug sau tseg tias ntawm lwm cov khoom siv hauv tsev siv los tsim lub ru tsev, cov vov tsev hlau yog qhov nrov tshaj plaws thiab tshwj xeeb tshaj yog nrov.
Cov khoom siv no tuaj yeem faib ua universal. Nws tuaj yeem ntsia tau rau ntawm yuav luag txhua yam ntawm qhov chaw thiab cov tsev ntawm txhua qhov tsim.
Nyob rau hauv ntau zaus, vov tsev hlau yog siv rau kev tsim kho ntawm pej xeem ntau-storey vaj tse, tsev, tsev lag luam thiab chaw ua lag luam. Tsis tas li, cov khoom siv hauv tsev yog qhov tseem ceeb thaum kho lub ru tsev, vim qhov no tsis tas yuav rhuav tshem lub ru tsev qub.
ru tsev hlau ua los ntawm cov ntawv galvanized muaj ntau qhov zoo dua lwm cov khoom siv hauv tsev uas tsim los rau kev siv zoo sib xws.
Ua ntej, galvanization yog yooj yim heev rau siv thiab muaj tus nqi tsim nyog. Cov vov tsev tuaj yeem ua tiav ntawm lub ru tsev ntawm txhua qhov geometry.
Qee qhov xwm txheej, kom yooj yim dua, vov tsev hlau yog ua los ntawm galvanized yob. Nws yuav tsum raug sau tseg tias cov khoom siv sib zog dua li slate thiab lwm yam vov tsev, uas ua rau nws yooj yim rau nruab, txo tus nqi tag nrho ntawm lub tsev. Tib lub sijhawm, kev thauj mus los kuj yuav pheej yig dua.
Txawm li cas los xij, qhov txiaj ntsig tseem ceeb ntawm vov tsev hlau yog lub neej ua haujlwm ntev. Ua tsaug rau galvanization, cov khoom muaj peev xwm tiv taus atmospheric influences thiab loads. Thiab cov txheej txheem polymer ntxiv yog kev tiv thaiv zoo tiv thaiv cov txheej txheem corrosion.
Cov txheej txheej galvanized polymer tuaj yeem ua ntau yam xim los muab koj lub tsev kov tus kheej. Lub tsev yuav txawv ntawm nws architectural expressiveness. Tsis tas li ntawd, vov tsev hlau, tus nqi uas ua rau nws pheej yig rau cov neeg siv khoom, yog cov khoom siv zoo ib puag ncig.
Muaj ntau txoj hauv kev los kuaj xyuas cov khoom siv vov tsev zoo. Cov hlau vov tsev zoo yuav tsum xeem dhau cov kev xeem hauv qab no.
Ntug ntawm daim ntawv raws thiab hla qhov dov yog ze ze, thiab tom qab ntawd nthuav dav dua rau hauv dav hlau. Cov kev ua yog rov ua dua. Thaum refolded, ntug yuav tsum tsis txhob muaj cov kua muag, thiab thaum rov folded, tsis muaj kab nrib pleb yuav tsum tshwm sim ntawm ob sab ntawm daim ntawv. Tshem tawm thiab khoovua rau lub ru tsev vov tsev nrog ib tug mallet (ntoo rauj).
Tsis tas li ntawd, los ntawm ib daim ntawv ntawm cov vov tsev hlau, ob lub strips ntsuas 3 x 10 centimeters yog txiav lengthwise thiab hla, clamped nyob rau hauv ib lub vise thiab khoov ntawm ib tug txoj cai kaum nrog rauj nyob rau hauv ib txoj kev, thiab ces nyob rau hauv lwm yam. Cov txheej txheem no yog nqa tawm kom txog thaum cov kab nrib pleb tshwm rau ntawm kab txaij. Cov vov tsev hlau zoo tuaj yeem tiv taus plaub lub folds tsis muaj cracking.
