Kab lus hais qhia ib qib zuj zus rau cov neeg tsim khoom tshiab yuav ua li cas thiaj li ua tau cov nplais hauv av kom raug, nrog rau yuav ua li cas thiaj li ua tau cov lus hais daws - qhov tseeb ntawm cov xuab zeb, dej thiab xis mas. Lub hom phiaj tseem ceeb ntawm cov screed - leveling hauv pem teb rau tom ntej tso rau nws ntawm ib txwm txheej npog - linoleum, vuas, parquet, laminate boards, thiab lwm yam. Tag nrho cov ntaub ntawv no yog qhov zoo rau kev kho kom zoo nkauj sab hauv - lawv yooj yim rau nruab, zoo nkauj heev thiab zoo nkauj hauv qhov tsos, ntxiv rau tus nqi pheej yig thiab ruaj khov. Tab sis lawv txhua tus muaj ib qho teeb meem tseem ceeb - kev teeb tsa cov khoom siv no yuav tsum tau nqa tawm ntawm cov plag tsev zoo kawg nkaus uas muaj cov pob zeb ua ke. Lub luag haujlwm no yog ua los ntawm cov screed.
Ua ntej pib ua haujlwm, koj yuav tsum nrhiav qhov hu ua siab tshaj plaws (lwm tus hu ua "zero level"). Txoj hauv kev yooj yim tshaj plaws thiab nrov tshaj plaws los ua qhov no yog siv cov dej lossis qib laser. Hauv ib chav twg, muaj lub cim rau ntawm phab ntsa uas xav tau thiab qhov siab yooj yim, uas, siv qib, raug xa mus rau lub ces kaum mus rau txhua phab ntsa ntawm lub tsev (chav tsev). Tom qab hloov daim ntawv lo, lawv tau txuas nrog kab rov tav. Ntxiv mus, hauv qhov chaw xav tau (feem ntau ntawm cov ces kaum), qhov kev ncua deb ntawm cov hauv pem teb uas twb muaj lawm thiab cov kab kos tau ntsuas. Qhov chaw uas qhov deb no yuav yog qhov tsawg tshaj plaws hauv tag nrho lub tsev (chav tsev) hu ua lub siab tshaj plaws, thiab txhua txoj haujlwm ntxiv yuav raug ua los ntawm qhov chaw no.
Npaj qhov saum npoo rau nchuav
Cov theem tom ntej ntawm kev ua haujlwm yuav yog kev npaj ntawm cov nplaim uas cov screed yuav raug nchuav. Cov av hauv av yuav tsum tau muab ntxhua kom huv thiab ntxhua; tsis muaj zog, qhov chaw tawg lossis tawg yuav tsum tau muab ntxuav thiab tshem tawm. Nws raug nquahu kom ua tiav qhov huv huv npaj nrog cov cement "mis" - qhov no yuav muab cov nplaum zoo dua qub rau lub hauv paus.
Kev npaj ntawm lub hauv paus tau ua tiav, thiab koj tuaj yeem txuas ntxiv nrog kev teeb tsa beacons - cov lus qhia uas cov screed yuav raug nchuav. Cov lus qhia no yuav tsum nyob sib nrug ntawm ib leeg kom deb li deb kom txoj cai-kev tsheb nqaj hlau siv rau qib cov tshuaj khib yuav tsum tau nchuav mus rau lawv. Nws yog qhov yuav tsum tau nthuav tawm lub beacons los ntawm qhov chaw siab tshaj, thiab cov tuab ntawm cov screed hauv qhov chaw no yuav tsum tsis pub tsawg dua plaub centimeters - txheej tuab tuaj yeem tawg. Cov lus qhia yuav tsum yog qib sib luag nrog txhua lwm yam thiab ruaj khov kho nrog cov tshuaj khib plaster.
Ua ntej pib txheej txheem ntawm kev nchuav cov tshuaj screed, nws yog qhov yuav tsum tau txhim kho daim kab xev nthuav dav raws cov phab ntsa. Qhov ua kom qhuav screed me ntsis nce me me thiab tuaj yeem swell lossis tawg, thiab daim kab xev nthuav dav yuav tiv thaiv nws los ntawm kev ua qhov tsis zoo.
Filling lub screed
Qhov ntawd yog txhua yam, kev npaj ua haujlwm tiav, thiab koj tuaj yeem pib ua haujlwm yooj yim tshaj plaws. Screed grout Nws yog tsim los ntawm cov xuab zeb, xis mas thiab dej, thiab ntau yam ntxiv tuaj yeem siv los ua yas (uas tuaj yeem hloov pauv nrog tsuaj zawv plaub hau lossis lwm yam tshuaj ntxuav tes). Yog tias kev ua haujlwm tau ua tiav ntawm qhov kub tsis txias, cov kua tshwj xeeb tau ntxiv rau cov tshuaj tov - "tiv thaiv kom khov".
Yuav ua li cas thiaj daws tau cov lus hauv pem teb
Cov screed yuav tsum tau muab sib xyaw siv cov khoom sib xyaw ua ke hauv qhov sib piv ntawm 1 txog 3: uas yog, 3 kg ntawm cov xuab zeb (quartz) thiab 1 kg ntawm cov cement (qib qhob tuaj yeem siv M200 lossis 250, lossis siab tshaj M300), ntxiv rau 0.45-0.55 liv dej rau 1 kg ntawm cov cement. Tus nqi dej tsis tuaj yeem txiav txim ua ntej, vim nws tsis tau xub paub tias hom av noo yuav siv rau hauv kev daws teeb meem li cas. Txawm li cas los xij, nws yuav tsum tsis txhob tuab heev los yog kua heev. Qhov kev daws teeb meem tau nchuav rau hauv ib feem ntawm qhov pom beacons thiab rub ua ke los ntawm txoj cai kom txog thaum tau txais lub tiaj tiaj.
Cov screed hliv yuav tsum qhuav tawm mus rau lub xeev uas koj tuaj yeem taug kev ntawm nws thiab tsis tso tseg cov cim tseg (zoo, lossis tawm me ntsis). Qhov no feem ntau tshwm sim rau hnub tom ntej.
Tom qab lub screed tau qhuav, nws yog qhov tsim nyog kom tau txais cov lus qhia, thiab cov khoom seem los ntawm lawv ncuav tshaj daws tshiab. Tom qab tag nrho cov no, lub screed tau ntub me ntsis nrog dej thiab txhuam nrog cov tshuaj txhuam tshwj xeeb, uas tuaj yeem yuav ntawm yuav luag txhua lub khw muag khoom kho vajtse. Nws raug nquahu kom npog lub ntsej muag ua tiav nrog cov yas qhwv kom nws tseem ntub tau ntev li ntev tau - yog li nws yuav muaj zog ntau dua.
