1.Cov ntsiab cai tseem ceeb yog dab tsi?
Lub hauv paus ntsiab lus "sab saum toj hauv qab": Thaum sib tshooj kab rov tav lossis ntsug, lub vaj huam sib luag sab saud lossis sab nrauv yuav tsum sib tshooj ntawm sab hauv lossis sab hauv los tiv thaiv cov dej nag los ntawm kev nkag mus vim lub ntiajteb txawj nqus lossis capillary.
Kev sib khi kom zoo: Siv cov khoom tshwj xeeb sealing ntawm cov pob qij txha tsim nyog kom tshem tawm txhua txoj hauv kev rau dej nkag.
Kev tiv thaiv electrochemical corrosion: Txawm hais tias ob qho tib si galvanized txheej thiab xim -coated steel sheets yog corrosion-resistant, electrochemical corrosion kuj tseem tuaj yeem tshwm sim nyob rau hauv qee yam mob yog tias ob lub hlau raug electrolyte (xws li dej nag) rau lub sijhawm ntev. Yog li ntawd, kev sib cais ntawm lub cev thiab kev sib khi yog qhov tseem ceeb heev.
2.Dab tsi yog txoj hauv kev thiab cov kauj ruam rau kab rov tav sib tshooj ntawm lub ru tsev seem?
Txheej Txheem: Muab lub vaj huam sib luag sab saud tso rau saum lub vaj huam sib luag qis. Qhov sib tshooj ntev nyob ntawm lub ru tsev txoj kab nqes thiab lub zog cua hauv zos, feem ntau tsis pub tsawg tshaj 150mm-250mm. Lub softer txoj kab nqes, ntev qhov sib tshooj.
Cov kauj ruam tseem ceeb:
Ntxuav qhov chaw tiv tauj: Ua tib zoo tshem cov plua plav, roj, thiab cov av noo los ntawm lub crest ntawm lub vaj huam sib luag hauv qab ntawm qhov sib tshooj.
Siv cov sealant: Siv cov hlua txuas txuas ntxiv ntawm cov huab cua tsis zoo silicone- tiv thaiv sealant rau thaj tsam sib tshooj ntawm lub vaj huam sib luag qis. Lub sealant sawb yuav tsum yog kwv yees li 8-10mm inch.
Tam sim ntawd ruaj ntseg qhov sib tshooj: Nias lub vaj huam sib luag sab saud thiab kho nws. Ruaj ntseg ob lub vaj huam sib luag rau lub purlin ua ke ntawm lub crest siv tus kheej -tapping screws. Cov ntsia hlau yuav tsum tau tsav mus rau sab saum toj ntawm lub crest, tsis yog ntug ntawm qhov sib tshooj.
Extrusion molding: Lub extruded sealant yuav tsim ib qho kev sib txuam, tsis muaj dej tsis sib haum, ua kom tiav qhov sib txawv.
3.Dab tsi yog txoj kev thiab cov kauj ruam rau longitudinal overlapping?
Txoj Kev: Qhov no yog qhov siab -kawg system ntawm kev zais cov fasteners. Ob sab ntawm cov vaj huam sib luag yog ua ntej- dov rau hauv cov txiv neej tshwj xeeb thiab poj niam tav.
Cov kauj ruam tseem ceeb:
Txoj hauj lwm: Tus txiv neej tav ntawm ib lub vaj huam sib luag yog embedded rau hauv poj niam tav ntawm lub vaj huam sib luag uas nyob ib sab.
Interlocking: Siv lub seam tshwj xeeb- lub tshuab xauv, cov txiv neej thiab poj niam tav tav yog nruj nreem sib txuas ntawm qhov sib koom ua ke, ua ib qho kev sib txuas ntsug mus txog 25-40mm siab.
Qhov zoo:
Tsis Tau Los ntawm -Screws: Screws tau muab zais hauv qab cov vaj huam sib luag thiab tsau rau cov purlins, tshem tawm qhov nyob hauv lub ru tsev saum npoo thiab hauv paus tiv thaiv kev xau.
Thermal Expansion thiab Contraction: Lub kaw lus ntsug ntsug tso cai rau cov panels swb vim qhov kub hloov pauv, tsis txhob muaj kev ntxhov siab.
High Wind Resistance: Lub xauv ntsug sib koom ua ke muaj cua siab heev uplift kuj.
Kev siv tau: Txoj kev no yuav tsum tau siv cov cuab yeej tshwj xeeb thiab ua ntej - tsim cov vaj huam sib luag ntsug, thiab feem ntau yog siv rau lub ru tsev ntawm cov tsev loj loj thiab cov chaw tsim khoom.
4.Dab tsi yog cov txheej txheem thiab cov txheej txheem los tuav kev sib koom ua ke ntawm cov tsev yooj yim lossis ib ntus?
Txoj kev: Overlapping + Tshwj xeeb Accessories
Cov Lus Qhia: Tsuas yog hla ib lub rooj tsavxwm mus rau lwm qhov, tsim ib lub trough lossis crest.
Cov kauj ruam tseem ceeb:
Siv lub hau dej tsis muaj dej: Saum qhov sib tshooj, siv cov xim -coated steel waterproof cap thiab ruaj ntseg rau ob sab nrog screws.
Thov sealant: Siv cov sealant rau thaj tsam hauv qab ntawm qhov chaw sib cuag ntawm lub hau thiab lub rooj tsavxwm txhawm rau txhim kho cov dej tsis zoo.
Qhov zoo: Kev tsim kho yooj yim, tus nqi qis.
Disadvantages: Tsawg aesthetically pleasing, tsis tshua muaj check dua ntsug sib koom tshuab.
5.Dab tsi yog cov ntsiab lus tseem ceeb thiab cov txheej txheem xaiv cov khoom?
Kev xaiv Sealant:
Qhov nruab nrab, huab cua - silicone sealant yuav tsum tau siv. Tsis txhob siv acidic silicone sealant, raws li nws yuav corrode galvanized txheej thiab xim txheej.
Cov xim sealant yuav tsum zoo sib xws rau cov xim vaj huam sib luag rau kev zoo nkauj.
Kev xaiv Fastener:
Tus kheej -drilling screws nrog EPDM waterproof washers yuav tsum tau siv.
Lub ntsia hlau ntev yuav tsum txaus kom nkag mus rau tag nrho cov vaj huam sib luag thiab kos yam tsawg kawg 25 hli rau hauv cov qauv hauv qab (xws li purlins).
Cov ntsia hlau yuav tsum tau tsav hauv vertically thiab nruj kom txog thaum lub tshuab ntxhua khaub ncaws me ntsis deformed thiab ntws tawm ntawm lub vaj huam sib luag nto. Overtightening yuav tsum tau zam kom tsis txhob cuam tshuam lub tshuab ntxhua khaub ncaws lossis vaj huam sib luag.
Overlap Direction:
Nyob rau hauv lub ru tsev, transverse overlaps yuav tsum tau nrog cov dej ntws, piv txwv li, lub sab sauv vaj huam sib luag overlaps lub sab vaj huam sib luag. Overlaps tiv thaiv cov dej ntws yog nruj me ntsis txwv.
Ntxuav thiab tiv thaiv:
Xyuas kom txhua qhov chaw sib tshooj yog huv, qhuav, thiab tsis muaj roj ua ntej thov.
Ntxuav cov sealant ntau dhau tam sim tom qab thov.
