Qhov kub thiab txias ib puag ncig kuj yog ib qho tseem ceeb cuam tshuam rau qhov zoo ntawm sab nrauv phab ntsa rwb thaiv tsev, yog li peb yuav tsum tau them sai sai rau qhov teeb meem no thaum lub caij ntuj no kev tsim kho, thiab yuav ua li cas ua kom cov phab ntsa rwb thaiv tsev nyob rau hauv lub caij ntuj no.
Yuav tsum paub txog qhov kub thiab txias
Ua tib zoo saib xyuas huab cua huab cua txhua lub sijhawm thiab ua kom nrawm ntawm qhov kub thiab txias. Yog tias huab cua txias thiab los nag thiab daus, kev tsim kho yuav tsum tau nres tam sim ntawd. Tsis tas li ntawd, nws yog ib qho tsim nyog los xyuas kom meej tias qhov kev tsim kho kub tsis tsawg dua 5 degree, txwv tsis pub tsuas yog lub sijhawm kho yuav hloov pauv, tab sis kuj yog qhov zoo ntawm cov khoom yuav raug puas ntsoog tom qab cov khoom khov, ua rau tawg thiab txo qis. dej tsis kam, uas cuam tshuam rau qhov zoo ntawm tag nrho sab nrauv phab ntsa rwb thaiv tsev.
Sab nrauv phab ntsa rwb thaiv tsev
Thaum lub sij hawm tsim kho, kev saib xyuas yuav tsum tau them rau:
1. Cov dej-cement piv thiab cov kua nplaum-cement piv yuav tsum tau siv nyob rau hauv qhov kev teev tseg. Tsis txhob muab cov khoom sib tov sib xyaw ua ke, txwv tsis pub, nws yuav ua rau lub sijhawm teem sijhawm.
2. Cov ntaub mesh tsis tuaj yeem tsau rau hauv dej kom tiv thaiv cov ntaub mesh los ntawm kev khov.
3. Thaum plastering saum npoo, sim xaiv lub sijhawm tav su rau kev tsim kho kom txo tau qhov cuam tshuam ntawm qhov kub thiab txias.
4. Vim tias qhov kub thiab txias, lub sijhawm ua npuas dej thiab kho lub sijhawm ntawm cov styrofoam yog ntev, yog li lub sij hawm rau kev sib tsoo ntawm lub rooj tsavxwm thaum lub sij hawm tsim kho yuav tsum tau ncua kom tsis txhob sib tsoo cov styrofoam ua ntej nws yuav kho.
Sab nrauv phab ntsa rwb thaiv tsev
1. Cia cov ntaub ntawv thaiv phab ntsa sab nraud:
Tag nrho cov ntaub ntawv ua kua lossis cov khoom siv pasty (xws li imitation cib dai kom zoo nkauj mortar, plastering compound rau ob lub ntsiab lus plastering mortar, tiag pob zeb xim / acai pob zeb, styrofoam, thiab lwm yam) yuav tsum muab cia rau ntawm qhov kub tsis qis dua 5 degree thiab muab tso rau hauv. sab hauv tsev thiab npog nrog paj rwb xav kom nce qhov kub thiab txias. Tag nrho cov ntaub ntawv hmoov yuav tsum muab cia rau hauv qhov chaw qhuav.
2. Nws yog nruj me ntsis txwv tsis pub ntxiv tej yam khoom pab xws li thaum ntxov lub zog tus neeg sawv cev thiab antifreeze rau tiv thaiv mortar, bonding mortar, thiab ntau yam khoom txhawb nqa ntawm lub tuam txhab. Anti-sizing agents thiab thaum ntxov-lub zog cov neeg ua haujlwm tsuas yog ua haujlwm ntawm cement hardening thiab tsis muaj kev cuam tshuam rau kev tsim cov yeeb yaj kiab polymer.
3. Txij li thaum lub caij ntuj no, ntau qhov chaw tsim kho yuav raug kaw sai sai, thiab cov neeg muag khoom yuav tsum tau npaj cov khoom siv kom tsis txhob muaj cov khoom siv ntau dhau. Qhov chaw cia khoom ntawm qhov chaw tsim kho yog qhov tsis zoo rau cov khoom siv hluav taws xob sab nraud, ua rau tsis tsim nyog poob.
