I. Roofing Liner: The Building's "Second Line of Armor"
Xav txog lub ru tsev liner yog ib qho tseem ceeb nruab nrab txheej npog cov txheej txheem purlins thiab muab tso rau hauv qab ntawm cov dej saum toj kawg nkaus. Nws yuav tsum tsis tsuas yog ua kom muaj kev ruaj khov, du puag rau cov khoom siv dej tsis zoo, tab sis ib qho uas muaj zog txaus los tiv thaiv cua thiab nag thiab kev thauj khoom ib ntus vim cov neeg ua haujlwm.

Sheet Material Selection yog qhov tseem ceeb:
Thickness thiab lub zog:
Ntawm tag nrho, peb yuav qhia cov ntawv tuab ntawm tsawg kawg 6 hli rau cov vov tsev. Cov nplooj ntawv tuab (piv txwv li, 8 hli lossis ntau dua) yuav tsim nyog nyob rau thaj tsam ntawm cov cua kub siab lossis daus daus. Load ib txwm suav nrog raws li cov kev cai hauv lub tsev thiab cov nplooj ntawv uas yuav tsum tau xaiv los ua tus account txaus khoov lub zog.
Huab cua Resistance yog qhov tseem ceeb:
Ib txwm siv huab cua-cov fiber ntau cement boards. Lawv muaj kev ruaj ntseg zoo thiab muaj zog nyob rau hauv qhov chaw ntub dej thiab yuav tsis hmoov los yog warp vim rov ntub-qhuav cycles. Tsis yog- huab cua- cov boards tiv taus yuav tsum tsis txhob siv sab nraum zoov lossis hauv qhov chaw uas muaj dej noo.
Kev kho deg:
Siv lwm cov ntawv sandblasted thiaj li tau txais qhov ntxhib saum npoo. Qhov no yuav pab txhim kho adhesion ntawm waterproofing membranes (bitumen membranes thiab PVC / TPO films) rau lub substrate, tiv thaiv lub glide ntawm qhov chaw thiaj li ua rau kom muaj kev sib raug zoo ntawm lawv.

Kev tsim kho: Cov ntsiab lus tseem ceeb

Frame Installation:
Lub batten txhawb nqa purlins (ntoo lossis lub teeb steel joists) yuav tsum tau muab tso rau ntawm lub rooj sib tham pom zoo los ntawm pawg thawj coj saib xyuas. Kev loj hlob tuaj yeem ua rau cov laug cam tsis muaj zog, vibrate lossis tejzaum nws tawg. Raws li txoj cai ntawm tus ntiv tes xoo, qhov chaw nruab nrab ntawm qhov nruab nrab ntawm lub ru tsev joists yuav tsum tsis pub tshaj 610mm thaum 6 hli boards siv rau vov tsev.
Laying thiab Fixing:
Cov sab ntev ntawm cov laug cam yuav tsum tau txhawb nqa los ntawm cov joists, thiab cov luv luv -kawg pob qij txha yuav tsum poob ntawm qhov nruab nrab ntawm cov joists.
Tawm qhov khoob yog qhov tseem ceeb! Qhov sib txawv ntawm 3-5 hli yuav tsum tau ua kom ntseeg tau ntawm cov laug cam ntawm tag nrho plaub ntug. Fiber cement boards yuav nthuav thiab compress ntawm lub caij, nws raug nquahu kom tawm ntawm 3/8 "qhov sib txawv ntawm cov npoo; undrained los ntawm quaj qhov.
Kho li no kho nrog corrosion-cov ntsia hlau tshwj xeeb (raws li stainless lossis galvanized tus kheej-tapping screws). Screws yuav tsum yog tsawg kawg yog 10 hli (0.39 nyob rau hauv) ntawm ntug ntawm lub rooj tsavxwm thiab 15 hli (0.59 nyob rau hauv) los ntawm cov ces kaum. Lawv yuav tsum tau txav mus los ntawm cov joists nrog lub siab zoo ntawm qhov tob, tab sis yuav tsum tsis txhob raug cranked nruj heev vim lawv ntshai tsam lawv yuav tawg lub rooj tsavxwm.
Kev kho mob sib koom:
Rau cov ru tsev uas yuav tsum tau muaj dej tsis zoo, nws raug nquahu kom siv cov khoom siv siab - zoo sealant los sau cov qhov khoob ntawm cov laug cam, tsim cov txheej txheem txuas ntxiv. Tsis tas li ntawd, tag nrho cov npoo npoo thiab txiav qhov qhib yuav tsum tau muab kaw kom zoo los muab kev tiv thaiv noo noo.
II. Pem Teb Substrate: Quiet thiab Khoom "Stage Foundation"
Hauv pem teb substrate yog lub hauv paus zais uas txhawb cov txheej txheem kawg (ntoo hauv pem teb, vuas, ntaub pua plag, thiab lwm yam). Nws yog ib qho tseem ceeb rau hauv pem teb flatness, suab rwb thaiv tsev, thiab tag nrho cov solidity underfoot.
Cov ntsiab lus tseem ceeb ntawm Pawg Thawj Coj:
Thickness thiab load- bearing muaj peev xwm:
Cement fiber boards rau cov plag tsev feem ntau yog 12 hli rau cov tsev nyob; Txawm li cas los xij, thaj chaw lag luam tuaj yeem hu rau 15 hli, 18 hli, lossis txawm tias tuab dua. Cov yam ntxwv tseem ceeb yog sab saum toj - qhov cuam tshuam thiab khoov qhov nro uas tso cai rau lub vaj huam sib luag fiber ntau kom nthuav tawm cov khoom hnyav thiab yog li tiv thaiv kev nyuaj siab hauv zos.
Dej tsis kam, zoo dimension stability:
Feem ntau, txawm tias sab hauv ntawm cov plag tsev tuaj yeem ntub los yog muaj kua nchuav rau ntawm lawv. Yog li, nws mus yam tsis tau hais tias peb yuav tsum xaiv cov laug cam uas muaj siab - ntom thiab qis - nqus. Qhov ntawd yog ib txoj hauv kev zoo heev los tiv thaiv kev nkag mus rau cov dej noo, tiv thaiv lub rooj tsavxwm lub rooj tsavxwm, thiab tib lub sijhawm khaws cov ntoo tiav (hauv cov ntoo hauv pem teb) tiv thaiv.
Surface Quality thiab Health:
Hauv pem teb baseboard yuav tsum muaj qhov ntom ntom ntom ntom ntom kom yooj yim rau kev ua tiav daim ntawv thov thiab kev teeb tsa. Nyob rau tib lub sijhawm, nws yuav tsum ua kom tau raws li qhov nruj tshaj plaws hauv tsev huab cua zoo thiab ib puag ncig cov qauv ntawm lub teb chaws ntawm lub hauv paus chiv keeb (xws li, VOC emissions qis thiab asbestos- ntawv pov thawj dawb).
Installation rau Seamless Finish:
Kev npaj hauv paus:
Txawm hais tias siv lub cav ntoo lossis cov cement mortar leveling txheej, lub hauv paus yuav tsum ruaj khov, qhuav, thiab tiaj tus. Txhua qhov tsis sib xws yuav raug xa mus rau qhov chaw tiav.
Laying Direction:
Boards yuav tsum tau muab tso rau perpendicular mus rau lub hauv paus kev txhawb nqa joists kom ua kom lub zog ntawm cov qauv. Cov pob qij txha yuav tsum tau staggered kom tsis txhob txuas txuas ntxiv -cov pob qij txha.
Fixing thiab Spacing:
Siv cov kev tiv thaiv corrosion-cov ntsia hlau tiv taus zoo ib yam li cov siv rau vov tsev, fastening cov laug cam rau txhua qhov joist ntawm 150-200 mm. Ib yam li ntawd, 2-3 hli expansion sib koom ua ke yuav tsum tau nyob ib ncig ntawm lub perimeter thiab nruab nrab ntawm cov laug cam. Qhov sib txawv no tuaj yeem sau nrog grout kom ua tiav qhov txuas ntxiv, ruaj khov, thiab suab nrov -txo cov txheej txheem.
Joint Reinforcement:
Siv cov kab nrib pleb -cov ntaub nplaum tiv taus thiab hloov pauv hloov mus rau cov pob qij txha ntawm cov laug cam thaum siv cov tawv tiav zoo li cov vuas luaj ceramic. Qhov no txhim kho lawv qhov kev tiv thaiv kom tawg thiab, yog li, cov vuas tsis tau tawg raws cov pob qij txha.
