Fiber Cement Board Installation (Pab ntsa / Qab nthab)
1. Kev npaj substrate thiab Keel
Keel Xaiv: Lub teeb steel keel lossis hluav taws kub- feem ntau siv ntoo keel.
Kev tswj qhov sib nrug: Qhov chaw nruab nrab - mus rau - nruab nrab qhov sib nrug ntawm qhov keel feem ntau yog 600mm; yog tias phab ntsa qhov siab tshaj 4m, ntxiv kab rov tav bracing keels yuav tsum tau raws li tus tsim.
Leveling thiab Kho: Ua ntej kev teeb tsa, qhov verticality thiab flatness ntawm keel yuav tsum raug kho siv lub laser qib lossis cov kav dej. Qhov yuam kev yuav tsum tau tswj nyob rau hauv qhov kev tso cai; Txwv tsis pub, lub board nto yog feem ntau deformation.
2. Board txiav thiab ua ntej- kho
Fiber Cement BoardCov cuab yeej txiav: Siv lub tes tuav cov hniav saws lossis lub tshuab txiav tshwj xeeb. Tiv thaiv koj tus kheej los ntawm cov plua plav tsim thaum txiav.
Kev kho sealing: Ua ntej kev teeb tsa, nws raug nquahu kom siv lub tsho tiv no ntawm cov xim dawb sealing rau ob sab ntawm lub rooj tsavxwm kom tsis txhob ya raws - ntxias deformation thiab txhim kho cov adhesion ntawm txheej txheej. Chamfering: Yog tias cov npoo ntawm cov vaj huam sib luag tsis chamfered ntawm lub Hoobkas, cov pob qij txha yuav tsum tau chamfered (V-groove) ntawm - qhov chaw rau tom ntej caulking.
3. Txhim kho kev teeb tsa
Fixing Sequence: Kho maj mam los ntawm qhov nruab nrab ntawm lub vaj huam sib luag sab nraud kom tsis txhob muaj qhov tsis sib xws los ntawm kev ntxhov siab sab hauv.
Ntsia Hlau Specifications: Siv tus kheej kheej kheej -tapping screws. Cov ntsia hlau deb ntawm phab ntsa panels feem ntau yog 200-300mm, thiab los ntawm qab nthab panels yog 150-200mm.
Ntug Qhov Kev Xav Tau: Qhov nruab nrab ntawm lub qhov ntsia hlau yuav tsum yog 10-15mm los ntawm ntug ntawm lub vaj huam sib luag, thiab tsawg kawg 50mm los ntawm lub ces kaum kom tiv thaiv ntug chipping.
Kev kho Counterhead: Tom qab ntsia hlau ntsia hlau, cov ntsia hlau yuav tsum yog 0.3-0.5mm hauv qab ntawm lub vaj huam sib luag nto, thiab cov tshuaj tiv thaiv xeb yuav tsum tau siv rau lub taub hau ntsia hlau tam sim ntawd.
4. Kev kho mob sib koom ua ke
Gap: Qhov sib txawv ntawm kwv yees li 5 hli yuav tsum tau sab laug ntawm cov laug cam (5 hli pom zoo rau sab nrauv phab ntsa, 3 hli rau phab ntsa sab hauv) kom tsis txhob tawg vim thermal expansion thiab contraction.
Catalyzing: Tom qab ntxuav qhov sib txawv, sau nws nrog ib qho tshwj xeeb elastic caulking compound lossis nplaum - hloov kho putty, tom qab ntawd muab cov ntaub nplaum tiv thaiv - tawg mesh. Tom qab ziab, xuab zeb nws du.
II. Kev txhim kho ntawm Ntoo Sawb Phab Ntsa Vaj Huam Sib Luag (Khoom Phab Ntsa Vaj Huam Sib Luag / Glattice)
1. Kev tshuaj xyuas txheej txheem thiab qib theem
Smoothness Requirements: Cov phab ntsa nto flatness yuam kev yuav tsum tsis pub tshaj 4-5mm. Cov cheeb tsam tshaj qhov kev txwv no yuav tsum tau kho nrog plaster lossis qib mortar; txwv tsis pub, cov ntoo strips yuav tsim cov qauv wavy.
Moisture-proofing Treatment: Thawj phab ntsa yuav tsum tau coated nrog noo noo- pov thawj xim. Sab nraum qab ntawm cov ntoo thav duab los yog strips yuav tsum tau coated nrog anti-corrosion, kab- pov thawj, thiab hluav taws kub- retardant xim thiab tso cai kom qhuav. 2. Keel System Siv
Keel Spacing: Kho raws li qhov dav ntawm cov ntoo strips. Feem ntau, qhov ntsug keel qhov sib nrug yog 300-400mm, thiab kab rov tav keel qhov sib txawv yog 400-600mm.
Txhim kho txoj kev: Siv cov bolts expansion los kho cov ntoo keel rau ntawm phab ntsa, xyuas kom cov keel nto nyob rau tib lub dav hlau (qhov yuam kev tsawg dua lossis sib npaug li 2 hli).
Lwm txoj kev daws teeb meem: Yog tias cov phab ntsa saum npoo yog tiaj tus, koj tuaj yeem siv cov ntsia hlau ncaj qha -dawb nplaum + pneumatic rau tes los kho cov kab ntoo. Txawm li cas los xij, rau qhov loj - thaj tsam kev tsim kho, nws raug nquahu kom ua ntej tsim lub keel lub hauv paus kom ntseeg tau tias ua pa thiab flatness.
3. Cov txheej txheem kev teeb tsa ntoo
Layout Rehearsal: Ua ntej kev teeb tsa, rov-tawm cov ntoo strips rau hauv av, kho cov xim sib txawv, thiab muab cov strips ntoo nrog cov nplej sib txawv hauv cov ces kaum lossis qhov tsis pom tseeb.
Txhim kho txoj kev:
Txoj Kev Nthuav Tawm: Tsav cov ntsia hlau pneumatic mus rau sab ntawm cov ntoo strips ntawm lub kaum sab xis 45-degree. Kho cov ntsia hlau qhov tom qab nrog putty ntawm tib xim.
**Snap-on/Concealed Nail Method:** Siv cov clips tshwj xeeb lossis sab grooves los zais cov ntsiab lus kho, ua rau tsis muaj qhov ntsia hlau thiab ua kom zoo nkauj dua.
** Gap Control: ** Qhov sib txawv ntawm 5-15mm yuav tsum tau sab laug ntawm cov ntoo strips (nyob ntawm tus qauv tsim). Siv qhov chaw thaiv qhov chaw kom paub meej qhov sib txawv.
4. Ntug tiav thiab kev tiv thaiv
** Kho kaum sab xis:** Sab hauv ces kaum yuav tsum tau butted ntawm 45-degree kaum sab xis. Sab nraud cov ces kaum tuaj yeem tau edged los yog them nrog pre-tiav zoo nkauj strips.
** Nto Txheej: ** Tom qab kev teeb tsa, ntxuav cov sawdust thiab siv cov roj siv roj lossis cov kua roj vanish rau kev tiv thaiv. Tsis txhob tso cua txias ncaj qha rau thawj xyoo los tiv thaiv kev tawg.
