Lub teeb-gauge steel furring channels yuav tsum muaj qhov tuab ntawm Ntau dua lossis sib npaug li 0.6 hli; ntoo furring strips yuav tsum tau kiln- kom qhuav thiab tsis muaj rot, kab puas, los yog warping. Adhesives thiab coatings siv ua ke yuav tsum ua tau raws li kev tiv thaiv ib puag ncig.
2. Cov ntsuas ib puag ncig: Formaldehyde emissions los ntawm qab nthab panels yuav tsum ua tau raws li E0 lossis ENF cov qauv. VOC cov ntsiab lus yuav tsum ua raws li cov kev cai uas tau teev tseg hauv GB 50325, "Code for Indoor Environmental Pollution Control of Civil Building Engineering," thiab cov ntaub ntawv yuav tsum tsis txhob muaj cov ntxhiab tsw txawv.
Cov qauv kev teeb tsa thiab kev tsim kho
1. Furring / Grid Installation: Qhov sib nrug ntawm cov channel tseem ceeb yuav tsum tau khaws cia tsis pub dhau 1,200 hli, thiab qhov sib nrug ntawm cov kab plaub hau yuav tsum tsawg dua lossis sib npaug li 400 hli (rau gypsum board ceilings); hanger spacing yuav tsum tsawg dua los yog sib npaug li 900 mm. L-zoo li tus yuav tsum tau muaj nyob rau ntawm lub qab nthab ces kaum los tiv thaiv kev tawg, thiab cov txheej txheem ntsia yuav tsum ruaj ntseg tsis muaj looseness los yog wobbling.
2. Kev teeb tsa vaj huam sib luag: Thaum tuav gypsum boards rau lub moj khaum, tus kheej -tapping screws yuav tsum tau muab tso rau qhov sib nrug ntawm 150-200 mm; ntsia hlau taub hau yuav tsum tau countersunk thiab kho tiv thaiv xeb, thiab nthuav dav ntawm 3-5 hli yuav tsum tau sab laug ntawm panels. Rau kev sib xyaw ua ke hauv qab nthab, cov pob qij txha yuav tsum tau yaug thiab seams uniform nyob rau hauv dav, tsis muaj warping los yog looseness.
3. Kev nthuav dav thiab ua tiav: Sab hauv thiab sab nraud cov ces kaum yuav tsum ncaj thiab kav dej; ntug trims yuav tsum haum nruj nreem tiv thaiv phab ntsa thiab lub qab nthab, tsis pom qhov khoob los yog curling npoo.
Cov qauv kev nyab xeeb thiab kev ua haujlwm
1. Load-cov kabmob muaj peev xwm: Qab nthab hauv cov chaw nyob hauv tus qauv yuav tsum txhawb nqa qhov hnyav tsawg kawg 3 kg / m²; Kev sib xyaw ua ke hauv qab nthab hauv chav ua noj thiab chav dej yuav tsum txhawb nqa qhov hnyav ntawm cov cuab yeej pabcuam xws li chav dej tso cua sov thiab cov teeb pom kev zoo, nrog rau tag nrho cov ntsiab lus txuas ntxiv kom ruaj ntseg thiab tsis txhob xoob lossis detachment.
2. Kev tiv thaiv hluav taws kub thiab noo noo: qhov ntsuas hluav taws kub ntawm gypsum board ceilings yuav tsum ua raws li cov cai tswj kev nyab xeeb hauv tsev; hlau furring channels thiab panels rau chav ua noj thiab chav dej qab nthab yuav tsum yog xeb - thiab ya raws - tiv thaiv corrosion los yog deformation thaum lub sij hawm ntev - siv.
3. Kev nyab xeeb hluav taws xob: Cov hlua hluav taws xob tau teeb tsa nyob rau hauv lub qab nthab void yuav tsum muab ntim rau hauv PVC conduit; kev sib txuas xov tooj yuav tsum yog tus qauv thiab zoo- insulated; Cov chaw tsim khoom siv hluav taws xob yuav tsum raug muab tso rau hauv qhov tseeb, tsis muaj qhov chaw nyob.
