Cov kua muag tawm thiab daim ntawv nplaum tso tseg rau 15 xyoo!
1.Txoj kev tsim kho tshiab ntawm steel qauv ru tsev
(1) Raws li hom phaj hlau lossis qhov sib txawv thiab qhov dav ntawm qhov sib koom ua ke, thiab raws li kev tsim qauv tsim qauv, xaiv qhov tshwj xeeb thiab qhov ntau thiab tsawg.
(2) So cov khoom sib koom ua ke ntawm cov hlau phaj kom huv.
(3) Pib nrog ib qho kawg ntawm lub phaj hlau, maj mam qhib daim kab xev ob sab, thiab muab daim kab xev khi rau ntawm lub puab tsaig ntawm lub phaj hlau qis hauv txoj kab ncaj nraim ntawm lub seam, thiab tom qab ntawd nias daim kab xev maj mam los ntawm tes. ua kom nws ruaj khov rau cov hlau.
(4) Tshem tawm cov ntawv tso tawm ntawm daim kab xev butyl roj hmab, nias lub phaj hlau ntawm txheej txheej sab saud ntawm qhov sib txuas rau hauv kev sib koom ua ke, thiab nyem qhov sib koom ua ke tom qab kev sib txuas, kom cov kev sib koom ua ke tau ruaj khov thiab kaw nruj nreem.
2. Kev tsim kho ntawm lub ru tsev gutters
(1) Tom qab txhim kho cov gutters prefabricated, ntxuav cov cement saum npoo ntawm cov gutters thiab siv tus neeg sawv cev kho mob.
(2) Tom qab tus neeg saib xyuas kev kho mob yog xav tias yuav tsum muaj zog, txhim kho lub flashing board kom ntseeg tau tias lub installation yog ruaj thiab nruj ua ke nrog cov phab ntsa.
(3) So lub flashing board huv si, thiab muab tshuaj txhuam ib leeg-ib sab aluminium ntawv ci butyl roj hmab daim kab xev ntawm qhov sib koom ntawm lub flashing board thiab cov cement phab ntsa, thiab nias lawv ua ntu zus kom nws ruaj khov;
Yog tias 80mm dav ib leeg-sab txhuas ntawv ci butyl roj hmab daim kab xev siv, lub phaj flashing tuaj yeem raug tshem tawm.
3. Kev tsim kho txoj kev ntawm lub ru tsev kho qhov project
(1) Ntxuav cov tev thiab delaminated qhov chaw ntawm lub ru tsev.
(2) So ntxuav cov roj stains, moss thiab lwm cov ntawv xov xwm uas cuam tshuam rau qhov adhesion ntawm qhov kho qhov chaw.
(3) Xaiv ib leeg-sided aluminium foil butyl roj hmab tapes ntawm txawv specifications raws li kev sib koom ua ke ntawm cov xau;
(4) Ncaj nraim npog qhov sib koom ua ke nrog ib leeg-sab txhuas ntawv ci butyl roj hmab daim kab xev;
(5) Yob cov khoom kho nyob rau hauv ib ntus tom qab kev sib txuas, yog li ntawd ib leeg-ib sab aluminium ntawv ci butyl roj hmab daim kab xev yog ruaj khov rau ntawm seam.
