V. Vim li cas feem ntau PS vaj huam sib luag Installation tsis ua ntej cov khoom puas
Thaum PS phab ntsa vaj huam sib luag installation mus tsis ncaj ncees lawm, lub vaj huam sib luag nws tus kheej tsis tshua muaj hauv paus. Cov khoom yog lub teeb yuag, dimensionally ruaj khov nyob rau hauv qhuav tej yam kev mob, thiab yooj yim txiav nrog txheem woodworking cuab yeej. Cov khoom qub no tsim qhov kev nkag siab tsis tseeb ntawm qhov yooj yim uas ua rau cov neeg teeb tsa kho PS panels zoo li plywood lossis phab ntsa qhuav, thiab qhov kev kho ntawd yog qhov pib ua tsis tiav.
Qhov feem ntau yuam kev installation yog adhesive incompatibility. Qee cov kuab tshuaj-raws li kev tsim cov nplaum muaj cov ntxhiab hydrocarbons uas yaj cov polystyrene ntawm kev sib cuag. Dab tsi zoo li cov nplaum nplaum huv si dhau los ua cov tshuaj tua kab mob uas noj rau hauv lub vaj huam sib luag substrate tom qab 24-48 teev. Lub vaj huam sib luag tsis poob ntawm phab ntsa tam sim ntawd. Nws tsim cov pob muag muag hauv qab ntawm qhov chaw ntawm txhua qhov chaw nplaum, thiab cov pob muag muag thaum kawg tau pom raws li kev nyuaj siab nyob rau hauv lub ntsej muag, feem ntau lub lis piam los yog hli tom qab kev teeb tsa tiav thiab tus neeg cog lus tau them nyiaj.
Qhov kev ua yuam kev thib ob yog kev siv tshuab fastening los ntawm qhov tsis txaus substrate thickness. PS ua npuas ncauj panels muaj qis ntsia hlau rub- tawm tsis kam tshaj ntoo lossis PVC ntawm qhov sib npaug ntawm cov tuab vim tias cov phab ntsa ua npuas ncauj deform thiab vau nyob ib ncig ntawm cov ntsia hlau threads es tsis koom nrog lawv. Lub ntsia hlau uas tau tsav los ntawm 10 hli PS vaj huam sib luag rau hauv phab ntsa stud yuav tuav-kom txog rau thaum ib tug neeg leans ib daig ntawm rooj tog tiv thaiv lub vaj huam sib luag, los yog lub qhov rooj slams thiab xa ib tug vibration mem tes los ntawm phab ntsa, los yog lub kub cycles txaus lub sij hawm los loosen lub ntsia hlau tuav ntawm lub crumbling ua npuas ncauj nyob ib ncig ntawm cov xov. Txoj kev daws tsis yog lub hau ntswj ntev dua. Nws yog qhov loj dua - lub tshuab ntxhua khaub ncaws hauv qab lub taub hau ntsia hlau txhawm rau faib lub zog clamping hla ntau qhov chaw ua npuas dej, lossis cov nplaum nplaum hla lub vaj huam sib luag tag nrho rov qab ntxiv los ntawm cov tshuab txuas rau ntawm ib puag ncig es tsis txhob cia siab rau cov fasteners raws li txoj kev txuas tseem ceeb.
Cov dej ntws tawm tom qab lub vaj huam sib luag yog qhov thib peb tsis ua hauj lwm vector, thiab nws yog qhov nyuaj tshaj plaws los kuaj xyuas vim tias cov pov thawj -pwm, nplaum tawg, ntug o - tshwm rau sab pom tsuas yog tom qab kev puas tsuaj tom qab lub vaj huam sib luag twb dhau lawm. PS ua npuas ncauj yog vapor retarder. Muab nws tso rau ntawm phab ntsa ntub dej los yog chav dej substrate uas tsis tau qhuav tag tom qab tshem tawm cov pobzeb, thiab koj tau tsim ib lub qhov rooj kaw qhov twg cov dej noo tsis muaj dej ntws tawm. Lub phab ntsa tom qab lub vaj huam sib luag tseem ntub. Cov nplaum nws thiaj li softens. Lub vaj huam sib luag ntug, tsuas yog ib feem ntawm lub kaw lus uas raug rau huab cua puag ncig, dhau los ua txoj hauv kev tawm mus rau cov khoom ntub dej, thiab qhov ntawd yog qhov o tshwm sim thawj zaug. Qhov kev tiv thaiv kev tiv thaiv yog qhov thaiv dej noo nyob rau sab substrate thiab qhov sib txawv ntawm huab cua -txawm tias 3-5 hli- tom qab lub vaj huam sib luag kom tso pa tawm.
Peb txoj cai uas tiv thaiv feem ntau PS vaj huam sib luag installation tsis ua haujlwm:
Kuaj cov nplaum rau ntawm lub vaj huam sib luag offcut ua ntej siv nws rau qhov chaw teeb tsa. Siv cov tshuab ntxhua khaub ncaws lossis cov phaj faib hauv qab txhua lub tshuab nqus tsev. Xyuas kom tseeb tias cov substrate noo noo cov ntsiab lus yog qis dua 5% ua ntej kaw lub phab ntsa kab noj hniav. Peb cov kauj ruam no ntxiv kwv yees li nees nkaum feeb rau cov txheej txheem kev teeb tsa thiab tshem tawm peb hom kev ua tsis tiav uas suav rau feem ntau ntawm PS phab ntsa vaj huam sib luag lav lav.
VI. Rau tus lej ntawm daim ntawv qhia tshwj xeeb uas qhia koj txhua yam txog lub vaj huam sib luag
Ib tus neeg muag khoom uas muab cov lus qhia ua tiav yog kev sib txuas lus ib yam dab tsi tshaj li qhov tseem ceeb ntawm nplooj ntawv. Lawv sib txuas lus tias lawv tau ntsuas lawv cov khoom raws li kev tswj hwm, tias lawv txaus siab sawv tom qab cov kev ntsuas hauv kev lag luam, thiab lawv nkag siab tias qhov hloov pauv twg ua rau kev ua haujlwm zoo. Tus neeg muag khoom uas tsuas yog muab tus nqi, ib daim duab, thiab tus nqi tuab yog qhov qhia tias qhov kev sib pauv yog hais txog kev txav cov khoom muag, tsis yog hais txog engineering ntawm qhov chaw.
Ntawm no yog rau qhov tseem ceeb uas tseem ceeb, nyob rau hauv qhov kev txiav txim siab ntawm qhov tseem ceeb, thiab txhua tus kwv yees li cas txog lub vaj huam sib luag ntsia:
