Tau siv cov cement los ntawm 1 m2 Cov screed yog xam raws li qhov kev daws teeb meem tau npaj. Cov qauv tsim ntawm txhua qhov sib xyaw muaj qhov sib txawv tseem ceeb raws li qhov xwm txheej ntawm cov sib tov, nws yog qhov sib xyaw ua ke, muaj pes tsawg txheej thiab dab tsi yog qhov los ntshav ntawm txoj kev sib tshooj Cov. Tau noj ntawm cov cement ntawm cov screed tseem thawj parameter rau txhua hom kev ua haujlwm tau ua rau lub ru tsev tiaj tiaj lossis hauv tsev, ntawm cov sam thiaj qhib.
Npaj theem
Txiav txim siab qhov ntim ntawm cov sib tov, tsom mus rau qhov siab ntawm screed
Ua ntej ua tiav nrog kev npaj ntawm kev daws teeb meem uas koj yuav tsum tau ua cov ntsuas ntawm tsis yog cov cement ncaj qha, tab sis kuj yog daws nws tus kheej.
Ua ntej tshaj plaws, nws yog qhov tsim nyog los ua kom raug thiab raug ntsuas qhov chaw lossis lub xaib, ntawm qhov twg screed yuav dej nyab.
Kev tshem tawm cov npoo uas cov screed yuav tau sau los ntawm kev tsim kho cov khib nyiab thiab cov khoom tsis tsim nyog, npaj mus rau cov lus txhais ntawm qib. Koj yuav tsum khij rau txhua phab ntsa uas siv qib laser ntawm qib lossis theem dej ntawm waterpas.
Muaj kev txiav txim siab qhov siab thiab tuab ntawm lub neej tom ntej screed, nws yuav ua tau kom muaj qhov kev daws teeb meem yog xav tau kom muaj lub tiaj tiaj.
Cov kev suav yog nqa tawm nyob rau 1 M2 thiab qhov no yuav pab txiav txim siab cov kev ua kom muaj kev sib haum xeeb, uas yuav tsum tsim cov kev daws teeb meem.
Tom qab txhim kho qib xoom, txhua qhov txiaj ntsig pom yuav tsum txuas nrog ib txoj kab du los txiav txim qib ntawm qhov siab ntawm qhov siab.
Qhov siab qhov sib txawv yuav tsum haum los ntawm 0.8 cm mus rau 5 cm
Lub siab txawv qib yog qhov kev ncua deb lossis qhov siab ntawm lub ntsiab (thawj) nto thiab cov kab txuas cov ntsiab lus siv tau siv. Cov txiaj ntsig tus nqi yuav tsum tsis pub tshaj 5 cm, tab sis nws yuav tsum tsis pub tsawg tshaj 0.8 cm. Txwv tsis pub, cov nplaim yuav tom qab muaj kev tawg tau thiab pib crumble.
Tshooj ntawm cov ncauj lus: Yuav ua li cas dai lub qab nthab eaves ua koj tus kheej
Kev txiav txim siab Maslim tau siv rau 1 M2 screed, nws yuav tsum tau coj mus rau hauv tus account thiab nws cov nta. Piv txwv li, siv cov khoom siv Portland los npaj kev daws teeb meem, koj yuav tau siv me ntsis xuab zeb, nws txhais tau tias cov cement ntawm cov cement yuav raug txo.
Txhawm rau hauv tus account qhov peculiarity ntawm cov khoom siv hom yog tsim nyog vim tias nrog kev suav tsis raug cov screed yuav tsis muaj peev xwm tiv taus ib qho kev thauj khoom thiab yuav tsis ruaj khov.
Ua cov suav, nws yog ib qho tseem ceeb kom them sai sai rau cov CEMENT hom. Rau qhov kev npaj ntawm cov lus uas siv M500 hom hmoov, 5 seem ntawm cov xuab zeb yuav tsum tau thiab tsuas yog ib feem ntawm cov xis, thiab yog tias M300 hom xav tau koj ntu.
Nyiaj them
Txhawm rau npaj cov khoom sib xyaw zoo, zam kev rov ua dua tshiab ntawm cov ntaub ntawv hauv tsev thiab, raws li, cov nyiaj yuav tsum ua kom tiav cov kev xam. Nws yuav tsim nyog los qhia meej tsis tsuas yog cov Caas hom, tab sis kuj nta xws li:
- lub xub ntiag ntawm cov yas hauv nws;
- sulphate tsis kam;
- feem pua ntawm cov tshuaj ntxiv;
- Lub nra theem uas txheej txheej tsim los ntawm cov hmoov no muaj peev xwm nrog nrog nrog nrog.
Muab cov cheeb tsam ntawm chav rau qhov siab ntawm screed
Ua kom muaj kev muab qhov tseeb ntawm kev noj ntawm cov khoom los ntawm 1 sq.m. Koj tuaj yeem siv cov mis yooj yim. Tus nqi ntawm tag nrho cheeb tsam ntawm chav tsev yuav tsum tau muab khoo los ntawm qhov teeb tsa ntawm txoj kev tawm ntawm txoj hlua khi. Yog li, yog nyob rau hauv chav tsev, tag nrho thaj tsam ntawm uas yog 80 m2, cov screed nrog ib tuab ntawm 5 cm yuav tau sau, 80 m = 4 ntawm kev daws teeb meem.
Xav tias M500 hom kev hloov pauv M500 yuav raug siv ua kom tiav cov haujlwm, koj tuaj yeem txuas ntxiv kev xam:
Raws li tus qauv sau cov cub ib ntus, cov sib tov yuav tsum muaj 410 ntawm cov cement. Txhawm rau tsim cov screed hauv chav no, koj yuav xav tau:
4 M3 x 410 kg = 1640 kg m500 hom hmoov.
1640: 50 = 32.8 hnab (80 m2), qhov twg 50 yog qhov loj ntawm ib lub hnab Masas.
Qhov no txhais tau tias ntawm 1 M2 sib txuas hauv cov chav no koj yuav tsum tau siv sijhawm yuav luag 0.5 lub hnab xuab zeb, 1.5 hnab ntawm cov cim xis mas thiab 75 kg ntawm cov xuab zeb zoo. Yog xav paub cov ntsiab lus ntawm yuav ua li cas thiaj suav cov khoom siv rau cov screed, saib daim video no:
Tshooj ntawm cov ncauj lus: Cov kab hlau yas: hom thiab lawv siv
Thaum ua kev suav, nws yog ib qho tsim nyog yuav tsum tau coj mus rau hauv tus lej ntawm kev npaj ntawm kev daws los ntawm cov cement ntawm ntau hom.
Yog tsis ua raws li cov cai thiab kev ua txhaum ntawm cov txheej txheem thev naus laus zis ua rau kev tsim cov khoom tsis zoo thiab luv, tawg cov screed, uas yuav hloov sai sai thiab ua tsis tau rau kev siv.
