Txoj kev yog raws li nram no:
1 Ua ntej xyuas qhov teeb tsa, thiab tom qab ntawd siv 76mm aluminium alloy trench thiab m8 × 150 expansion bolts, tsau rau C20 pob zeb. Lub expansion bolts yuav tsum nruj nreem fastened thiab yuav tsum tsis txhob loosened. Tus naj npawb yuav tsum ua raws li cov qauv tsim. Yog hais tias lub aluminium alloy qhov seem yog 300 me me, nws yuav tsum tsis txhob tsawg tshaj li ob lub expansion bolts.
2. Txhim kho cov phab ntsa. Pib ntawm lub ces kaum ua ntej thiab kho nws yooj yim. Siv tuab aluminium fab rau sab hauv thiab sab nraud ntawm thawj lub kaum sab xis phab ntsa thiab txuas nrog phab ntsa phab ntsa nrog rivet. Qhov kev ncua deb yog 300 ~ 400. Lub kaum sab xis thib ob yuav tsum tau muab tso rau ntawm sab thiab khob nrog cov ntoo square kom haum nws nrog thawj kaum phaj. Cov txheej txheem installation yog tib yam li ua ntej. Kho lub perpendicularity thiab kab rov tav lub kaum sab xis ntawm ob lub kaum daim hlau, thiab tom qab ntawd kho cov footing, ob phab ntsa phaj thiab lub kaum ntse ntse aluminium nrog rivet. Txhim kho cov phab ntsa hauv ob qho kev qhia tib lub sijhawm, thiab kho qhov theem thiab qhov perpendicularity ntawm txhua phab ntsa uas tau teeb tsa. Lub phab ntsa thiab cov qauv hlau tseem ceeb txuas nrog thiab txuas nrog cov ntsia hlau, nrog cov ntsia hlau pitch Tsawg dua lossis sib npaug li 500 hli.
3 Tom qab kev teeb tsa ntawm phab ntsa, xyuas qhov kev sib txuas ntawm phab ntsa thiab nruab nrab ntawm cov phab ntsa thiab cov qauv hlau los txiav txim seb lawv puas ua tau raws li cov qauv tsim tau teev tseg hauv cov qauv tsim thiab cov kev xav tau rau kev ruaj ntseg ntawm phab ntsa, thiab xyuas seb qhov kev tsim kho zoo ntawm qhov chaw zais xws li cov kav dej zais. thiab cov khoom siv thiab qhov flatness ntawm phab ntsa phab ntsa ua tau raws li qhov yuav tsum tau ua. Nyob rau tib lub sijhawm, ua tib zoo xyuas qhov zoo ntawm cov phab ntsa panels kom ua tau raws li cov qauv tsim thiab cov kev cai tshwj xeeb. 4 Thaum txhim kho lub ru tsev vaj huam sib luag, thawj zaug xyuas seb cov qauv hlau puas yog tsim raws li tus qauv tsim, thiab xyuas seb cov kab ntawm phab ntsa vaj huam sib luag puas yog ib txoj kab ncaj nraim. Yog tias muaj qhov tsis sib xws, nws yuav tsum tau kho ua ntej. Tom qab kev tshuaj xyuas, lub ru tsev vaj huam sib luag yuav tsum raug thauj mus rau lub ru tsev, teem caij kom zoo thiab kho ib ntus. Thaum lub ru tsev vaj huam sib luag ntawm ib chav tsev raug ntsia, phab ntsa thiab lub ru tsev yuav tsum ruaj khov nrog rivet ntawm plaub fab ntawm chav tsev nrog lub kaum ntse ntse aluminium. Thiab txhua lub purlin thiab ru tsev vaj huam sib luag yuav tsum tau fastened los ntawm sab saum toj mus rau hauv qab nrog screws, nrog ib tug nruab nrab ntawm 500 hli. Tom qab tag nrho cov ru tsev panels raug ntsia, ridge phaj, gutter, eaves sab sauv phaj thiab lwm yam hniav thiab flashing qhov chaw yuav tsum tau ntsia. Qhov sib tshooj ntawm lub ru tsev fittings yuav tsum tau muab ntsia kom deb li deb ntawm cua kev taw qhia li sai tau. Qhov sib tshooj ntev yuav tsum siab dua lossis sib npaug li 60mm. Qhov sib tshooj yuav tsum tau muab khi nrog sealant, thiab qhov kev ncua deb ntawm fasteners yuav tsum tsawg dua los yog sib npaug li 500mm.
