Kev tsim cov pobzeb ru tsev yog ib kauj ruam tseem ceeb hauv kev txhais cov qauv tsim rau hauv lub ru tsev ua haujlwm. Nws qhov zoo ncaj qha txiav txim siab lub ru tsev kev ua haujlwm tsis zoo, kev nyab xeeb ntawm cov qauv, thiab kav ntev. Txhawm rau kom ntseeg tau tias cov txiaj ntsig kev tsim kho tau raws li qhov kev xav tau, kev ua raws li cov qauv hauv tebchaws thiab kev lag luam tseem ceeb yog qhov tseem ceeb, thiab cov txheej txheem ua kom zoo thiab ua tib zoo yuav tsum tau ua raws li tag nrho cov txheej txheem.
Thaum lub sij hawm npaj, qhov flatness, lub zog, thiab noo noo cov ntsiab lus ntawm lub ru tsev substrate yuav tsum tau xyuas raws li cov ntaub ntawv tsim thiab cov qauv tam sim no xws li "Roofing Engineering Quality Txais Specification." Lub substrate nto yuav tsum tsis muaj qhov pom tseeb tsis sib xws, xoob, thiab roj stains. Lub zog ntawm cov pob zeb lossis mortar substrate yuav tsum ua kom tau raws li qhov yuav tsum tau ua, thiab cov ntoo substrates yuav tsum tau tiv thaiv -corrosion thiab ya raws- pov thawj kev kho mob. Lub phiaj xwm txheej pobzeb yuav tsum tau tshuaj xyuas, qhia meej meej qhov chaw pib, sib tshooj ntev, thiab nthuav dav kev tsim kho ntawm lub ridge thiab eaves. Vuas thiab fasteners ntawm cov khoom sib xws thiab cov lus qhia tshwj xeeb yuav tsum tau npaj raws li kev siv tiag tiag. Rau kev tsim kho lub ru tsev pitched, yuav tsum muaj kev nyab xeeb kev ua haujlwm platform thiab kev tiv thaiv lub caij nplooj zeeg. Cov neeg ua haujlwm yuav tsum tau txais cov lus qhia txog kev nyab xeeb thiab hnav cov khoom tiv thaiv tsim nyog.
Tom qab kev kho substrate tiav, cov vuas yuav tsum tau muab tso rau raws li lawv cov yam ntxwv. Cov qauv qhia tias cov vuas vov tsev yuav tsum tau muab tso rau hauv qab mus rau sab saum toj, los ntawm cov eaves mus rau lub ridge, tswj cov dej ntws zoo ib yam thiab txoj kab nqes. Qhov sib tshooj ntawm cov ntaub ntawv sib txawv yuav tsum ua kom tau raws li qhov yuav tsum tau ua: qhov sib tshooj dav ntawm cov av nplaum thiab cov vuas luaj yuav tsum tsis txhob tsawg dua qhov tsawg kawg nkaus, thiab lawv yuav tsum tau kho nrog mortar lossis battens; cov vuas cement thiab cov vuas hluavtaws tuaj yeem cuam tshuam los yog sib tshooj raws li lawv cov tav los xyuas kom nruj nruj; cov vuas hlau yuav tsum siv cov ntug kaw kaw lossis tshwj xeeb fasteners los xyuas kom cov pob qij txha tsis tu ncua tsis muaj warping. Direct stepping ntawm pobzeb nto yog nruj me ntsis txwv tsis pub thaum lub sij hawm installation; thaum tuav thiab tso, ob txhais tes yuav tsum tau siv los txhawb nqa hauv qab, tsis txhob cuam tshuam los ntawm cov npoo thiab cov ces kaum.
Kev kho cov haujlwm yuav tsum ua kom tau raws li qhov yuav tsum tau muaj cua thiab av qeeg. Hom, qhov sib nrug, thiab qhov tob ntawm cov fasteners yuav tsum tau muab xam thiab txiav txim siab raws li qhov ntsuas cua hauv zos, txoj kab nqes ntawm lub ru tsev, thiab tus kheej - qhov hnyav ntawm cov vuas. Cov vuas hlau ru tsev thiab cov vuas hluavtaws yog feem ntau kho nrog tus kheej -tapping screws thiab cov ntxhua khaub ncaws tsis muaj dej. Cov tshuab ntxhua khaub ncaws yuav tsum sib haum nrog cov ntaub ntawv pobzeb kom tiv thaiv electrochemical corrosion. Cov pobzeb tsoos feem ntau yog kho nrog battens, tooj liab hlau, lossis galvanized steel hlau. Cov pob qij txha yuav tsum muaj kev ruaj ntseg tab sis tsis nruj heev kom tsis txhob muaj micro- tawg los ntawm kev nruj heev. Lub taub hau ntawm lub fastener yuav tsum tau yaug nrog los yog me ntsis qis dua cov pobzeb nto kom ntseeg tau tias cov kua dej du thiab zoo nkauj.
Ntawm cov pob qij txha xws li ridges, eaves, gable phab ntsa, thiab skylights, kev tsim kho yuav tsum nruj me ntsis raws li cov lus piav qhia thiab cov qauv kev coj ua. Ridges yuav tsum tau them nrog tshwj xeeb ridge vuas los yog waterproof npog, thiab txoj kab yuav tsum ncaj thiab ruaj ntseg. Flashing thiab sealing cov khaubncaws sab nraud povtseg yuav tsum tau muab tso rau tsis tu ncua, nrog cov ces kaum sib npaug los yog obtuse, thiab ua kom nruj nrog cov khoom siv dej tsis zoo los tiv thaiv cov dej nag los ntawm qhov khoob. Tag nrho cov pob qij txha, kho cov ntsiab lus, thiab cov chaw ua tiav yuav tsum muaj kev ruaj ntseg tsis muaj dej thiab kaw.
Tom qab kev tsim kho, kev tshuaj xyuas zoo yuav tsum tau ua kom paub meej tias cov vuas tau zoo zoo nkauj, nruj sib tshooj, ruaj khov, thiab cov dej ntws tsis muaj kev cuam tshuam. Yuav tsum tau tshuaj tsuag dej los yog kev ntsuas dej kom ruaj khov yuav tsum tau ua kom paub tseeb tias cov dej tsis zoo. Tom qab kev tshuaj xyuas thiab kev pom zoo, lub xaib raug ntxuav, thiab cov ntaub ntawv khaws cia uas muaj cov ntsiab lus ntawm cov txheej txheem tsim kho, cov khoom siv batch, cov txiaj ntsig kev xeem, thiab cov ntaub ntawv kho dua tshiab yog tsim los muab lub hauv paus rau kev lees paub zaum kawg thiab kev saib xyuas tom qab.
Cov txheej txheem kev tsim cov pobzeb ru tsev tsis yog tsuas yog cov kev qhia tshwj xeeb xwb tab sis kuj lav qhov zoo thiab kev nyab xeeb. Tsuas yog ua raws li cov txheej txheem nruj me ntsis hauv txhua theem- los ntawm kev npaj tsim kho thiab kev kho substrate mus rau kev tso thiab kho, kev tiv thaiv dej ntawm cov ntsiab lus tseem ceeb, thiab kev lees paub- tuaj yeem ua tau ntev- lub sijhawm ruaj khov ntawm lub ru tsev, muab kev tiv thaiv ruaj khov thiab txhim khu kev qha rau lub tsev.
