Ntau tus neeg xav tias kev txhim kho fiber ntau cement boards yooj yim -tsuas yog ntsia lawv rau. Tab sis ua siab ncaj, tom qab ntau xyoo hauv kev lag luam no, kuv tau pom ntau qhov tsis ua tiav: cov laug cam tawg, pob qij txha, thiab txawm tias tag nrho cov phab ntsa ua xoob tom qab ob peb xyoos. Qhov teeb meem nyob qhov twg? Cuaj zaug ntawm kaum, nws yog nyob rau hauv "qhov chaw tsis pom"- cov joists thiab cov pob qij txha.
Ua ntej, tsis txhob nruab lawv nruj rau cov hlau joists.
Txawm hais tias muaj kev ua haujlwm zoo, ib qho ntawm cov yam ntxwv tseem ceeb ntawm fiber ntau cement boards yog tias lawv yuav nthuav dav lossis cog lus vim qhov hloov pauv ntawm qhov kub thiab txias. Txawm hais tias lawv muaj qhov qis qis dua ob qho tib si ntoo thiab yas (nrog rau ntau hom khoom), kev hloov pauv ntawm qhov kub thiab txias tuaj yeem ua rau muaj kev ntxhov siab sab hauv hauv fiber ntau cement boards.
Muaj ntau tus neeg tsim khoom, kom txuag tau sijhawm, ntswj cov laug cam kom nruj rau cov joists, siv cov qauv ntom ntom ntom ntom -yuav luag zoo li xaws khaub ncaws. Qhov tshwm sim? Thaum lub caij ntuj sov sov, cov laug cam tsis muaj chaw nthuav dav thiab xaus rau kev tawg ntawm cov pob qij txha.
Kuv cov lus qhia yog: muab cov laug cam ib co "yooj yim." Siv galvanized lub teeb steel keels, vim tias lawv qhov kev ruaj ntseg yog qhov zoo tshaj plaws ntawm cov ntoo (uas tuaj yeem hloov pauv thaum damp -ib tug "killer" rau cov cement boards). Thaum lub sij hawm installation, screws yuav tsum tsis txhob tsav mus ze rau ntawm ntug ntawm lub rooj tsavxwm; tawm tsawg kawg 10-15 mm ntawm clearance. Nws zoo li txoj siv hlua khi- yog nws nruj heev, nws yuav tsis xis nyob; me ntsis slack ua rau nws ruaj ntseg dua.
Thib ob, rau kev kho mob sib koom ua ke, tsis txhob cia siab rau "putty li kev kho-tag nrho."
Cov haujlwm txawv teb chaws feem ntau tshwm sim hauv cov cheeb tsam uas muaj qhov sib txawv ntawm huab cua, xws li cov suab puam kub ntawm Middle East lossis cov dej khov ntawm Northern Europe. Nyob rau hauv xws li ib puag ncig, yog tias koj tsuas yog sau qhov sib txawv ntawm ob lub rooj tsavxwm nrog cov putty zoo tib yam, qhov sib koom ua ke yuav pom zoo li "pob txha" hauv rau lub hlis.
Peb ib txwm hais qhia rau peb cov neeg siv khoom: pob qij txha tsis yog "sau" xwb - lawv yuav tsum tau kho kom zoo.
Tsuas yog siv mesh los yog elastic sib koom ua ke. Txoj kev ua kom raug yog ua ntej "bevel" qhov sib koom ua ke rau hauv V, tom qab ntawd sau cov sib koom ua ke nrog kev sib koom ua ke thiab siv cov ntaub nplaum tam sim ntawd thaum lub compound tseem "tuag me ntsis." Tom qab ntxiv lwm txheej ntawm qhov sib xyaw kom tawm ntawm qhov chaw, koj yuav muaj qhov sib koom ua ke elastically buffered.
Zoo ib yam li kev xaws ntawm lub duav elastic mus rau ib lub tsho, koj cov laug cam tuaj yeem txav me ntsis vim qhov kub thiab txias; Txawm li cas los xij, vim tias muaj qhov tsis sib haum xeeb ntawm ob daim ntoo ntawm qhov sib koom ua ke, cov pob qij txha yuav tsis tawg.
Thib peb, tsis txhob hnov qab txog waterproofing.
Fiber cement board yog dej resistant, thiab yuav submerged yam tsis muaj kev puas tsuaj rau nws tus kheej; Txawm li cas los xij, cov dej noo tuaj yeem ua rau cov joists puas thiab xeb tawm ntawm cov ntsia hlau.
Thaum ua haujlwm hauv chav dej, ntawm phab ntsa sab nrauv, thiab hauv qab daus ntub kuv tau pom ntau zaus uas yuav tsum tau ua dua tshiab vim tias cov khoom tau hais dhau los tsis tau muab coj los xav thaum lub sijhawm teeb tsa.
Khaws cov joists tawm hauv av: hauv av yog qhov chaw ntub dej tshaj plaws. Thaum txhim kho cov phab ntsa, tso cov roj hmab los yog PVC sawb ntawm lub hauv qab joist thiab hauv pem teb. Tsis txhob cia cov cement board thiab joists tuaj rau hauv kev sib cuag nrog hauv av. Txawm tias tsa lawv los ntawm tsuas yog 5 millimeters tuaj yeem txuas lub phab ntsa lub neej los ntawm ob peb xyoos.
Siv corrosion-cov ntsia hlau tiv taus: Koj yuav tsum tsis txhob siv tus kheej li niaj zaus-tapping screws. Siv stainless hlau screws los yog ob - xov tooj ntawm tes threaded rau tes nrog cov txheej txheem corrosion. Tsis tas li ntawd, thaum siv cov ntsia hlau ua khoom siv kho vajtse, lub taub hau ntsia hlau yuav tsum tau muab tso rau hauv qhov chaw ntawm lub rooj tsavxwm thiab lub qhov uas muaj epoxied resin zoo nkauj kom cov dej tsis tuaj yeem nkag mus rau hauv cov chaw no.
