Facade thiab ru tsev qauv nqa cov khoom tseem ceeb thoob plaws hauv lawv lub neej ua haujlwm tag nrho. Kev ua haujlwm ntawm cov khoom siv vov tsev ncaj qha nyob ntawm qhov zoo ntawm kev teeb tsa thiab xaiv cov khoom. Yog li ntawd, rau lub installation ntawm lub ru tsev, ru tsev screws rau hlau yog siv, uas yog resistant rau sab nraud aggression ib puag ncig. Txhawm rau kom tsis txhob muaj qhov tshwm sim ntawm xeb, nws yog ib qho tsim nyog yuav tsum siv cov qauv zoo nkaus xwb los txhawb lub ru tsev. Cov ntsia hlau tsim los siv cov cuab yeej siv niaj hnub no tsim nyog siv rau tsib caug xyoo.
Roofing self-tapping ntsia hlau yog cov khoom siv kho vajtse uas tsim los rau kev txuas cov khoom sib txuas thiab cov vuas hlau. Nyob rau hauv tsos, qhov no yog ib tug hlau pas nrig nrog ib tug ntsia hlau xov. Ib qho kawg ntawm tus pas nrig xaus nrog lub taub hau hexagonal, lwm qhov kawg nrog lub laum (nws tuaj yeem laum los ntawm cov khoom yuav tsum tau kho thiab lub hauv paus). Lub sharpening zoo ntawm lub ntsis thiab cov khoom steel tsis suav nrogua txhaum ntawm cov hlau nto nyob ib ncig ntawm lub qhov drilled. Xws li tus kheej tapping screws yog ua ob qho tib si nrog ib qho kev xyaum thiab nrog ib qho ntxiv.
txhawm rau xyuas kom tsis muaj dej tsis zoo ntawm kev sib txuas, lub ru tsev ntsia hlau ua tiav nrog lub tshuab ntxhua khaub ncaws galvanized nrog cov roj hmab gasket, uas yog ua los ntawm cov khoom siv roj hmab hloov kho. Nws yog nruj nreem nias rau hauv lub hauv paus ntawm aluminium washer. Thaum ntsia hlau ntsia hlau nyob rau hauv lub warp aav thiab nyob rau hauv tus txheej txheem ntawm re-tightening, lub gasket exhibits plasticity zog. Nws yog sealant. Cov roj hmab gasket tiv taus nag lossis daus, UV, kub heev, ozone.
Qhov zoo tshaj plaws thickness ntawm cov hlau uas lub ru tsev ntsia hlau xyaum yog 2.5 hli. 6-8 cov khoom siv rau ib square meter. Raws li txoj cai, lawv txuas nrog rau sab qis ntawm corrugated board yoj ntawm kev sib tshuam nrog lub crate ob peb centimeters hauv qab no cov kauj ruam protruding. Tom qab kho tus kheej tapping ntsia hlau rau hauv lub crate, cov roj hmab gasket ntawm lub tshuab ntxhua khaub ncaws deforms thiab hermetically sau qhov chaw nruab nrab ntawm lub taub hau ntsia hlau thiab cov vov tsev hlau. Tsis ntev tom qab lub tshuab ntxhua khaub ncaws vulcanizes thiab tsim ib qho impermeable sib koom ua ke.
Roofing hlau screws yog tsim los ntawm cov pa roj carbon siab. Zinc txheej ntawm tus kheej tapping screws yog siv electrolytically. Hauv qhov no, zinc txheej yog kwv yees li 20 µm. Nyob ntawm qhov chaw ntawm corrugated board yuav tsum tau txuas, pleev xim los yog galvanized self-tapping screws yog siv. Cov ntaub ntawv vov tsev niaj hnub muaj ntau yamxim ntau yam, yog li lub ru tsev ntsia hlau sib dhos nrog lub tshuab ntxhua khaub ncaws tuaj yeem pleev xim rau hauv ib qho xim raws li RAL lub rooj. Lub taub hau ntawm cov ntsia hlau, qhov chaw hauv qab lub hau thiab cov hlau txheej ntawm lub tshuab ntxhua khaub ncaws yog ua tib zoo pleev xim rau nrog cov xim polymer. Rau kev ua haujlwm ntev ntawm cov hmoov pleev xim yog ua tiav los ntawm txoj kev rauv.
Ib hom vov tsev screws yog tus kheej tapping ntsia hlau rau cov khoom siv hauv tsev nrog peb txheej txheej (sandwich panels). Muaj qhov ntev ntev, lawv muaj peev xwm tawg los ntawm cov txheej tsis muaj rwb thaiv tsev nyob hauv qab daim ntawv vov tsev thiab ncav cuag lub hauv paus. Cov qauv façade tso cai rau kev siv cov vov tsev tsis muaj lub tshuab ntxhua khaub ncaws.
