Khungu louma pansi ndi labwino kwambiri, koma njira yodalirika yochepetsera pansi, pomwe mapepala a gypsum amagawidwa pamtunda wosanjikiza.
Njira iyi yochezera pansi ili ndi ubwino wambiri, pakati pake - kulemera kochepa, komwe kumakupangitsani kuti musapitirize katundu pansi. Kuonjezerapo, kuyesa pansi ndi zowuma pamakhala wotchipa, mofulumira, kupeĊµa kuwononga kwambiri, mosiyana ndi njira ya mchenga yamchere. Komabe, mpweya wouma pansi uli ndi zovuta zake: ukuwopa chinyezi, ndiko kuti, sichivomerezeka kuti ugwiritsidwe ntchito m'zipinda zomwe zimatha kutentha (makasitini, malo osambira, attics), ndipo zimafuna kutseka madzi.
Pansi pa zouma zouma pali mpweya wambiri wa mpweya - filimu ya polyethylene yomwe imateteza pamwamba pazitsulo kuti zikhale zowonongeka ndi awiri awiri a konkire. Firimuyi imayikidwa mwamphamvu, ikuphatikizira makoma, mpaka kumtunda wa phulusa la zowuma. Zowuma pazitsulo zimafuna kuyika parafini, kapena pepala la bitume ngati mpweya wambiri. Ngati kuli koyenera, filimuyo imaphatikizidwa ndi pulogalamu yowonjezera voliyumu - polystyrene foam, ubweya wa mchere, ubweya wa magalasi kapena zipangizo zina zowonongeka. Kawirikawiri kuvomerezedwa kumayikidwa pambali, ndi chivundikiro cha 10 mm kuchokera khoma. Chotsatira chotsatira ndicho kubwerera. Sikuti imangowonongeka pansi, koma imalimbikitsanso phokoso ndi mpweya. Mosiyana ndi malingaliro ambiri olakwika, dothi loumala ndi dothi lokwanira likuletsedwa, monga mchenga wa dongo wokha (kufufuza), mchenga wa quartz, kapena slag yabwino-grained ntchito. Chotsalira chotsiriza chili ndi bolodi la pulasitiki.
Dry floor screed - teknoloji
Powonongeka pamapangidwe opangidwa ndi "wetyowa" (ntchito zowonongeka kwa madzi, fillers, etc.). Musanayambe kupuma pansi, m'pofunika kulimbana ndi zipangizo zonse mu malo okonzekera, kusinthasintha zochitika zonse zakuthupi ndi momwe zimakhalira kutentha ndi chinyezi , koma pakalipano tikugwira ntchito yofunikira yoyeretsa pansi kuchokera kumatala akale ndikusindikiza ming'alu pansi.
Tsopano, pogwiritsira ntchito beacon yapadera, timayika mlingo wamatabwa amtsogolo pamakoma ndikupitiriza kuika filimu yothetsera mpweya. Kuika filimuyi, monga momwe tanenera kale, kumapezeka pamakoma ndi pamasamba, pafupi ndi masentimita 15-20, ndipo ziwalo zonse zimalimbikitsidwa ndi tepi (m'mphepete mwa tepi). Kubwezeretsanso kumapangidwa malinga ndi mlingo wa kusagwirizana kwa kuphatikizana, kawirikawiri wosanjikiza wa mchenga wa dongo wosapitirira saposa 30-50 mm. Gwirizanitsani chophimbacho chophimba ndi ulamuliro wa pulasitiki womwe uli pakati pa ma mbiri awiri: kusunthani malamulo, kugwiritsa ntchito mbiri monga njanji, ndikuyika chizindikiro cha laser monga chitsogozo. Kenaka, timayika mapepala a GVL ndi kusamuka ndi kusiyana pakati pa mbale za 1 mm. Timayambira pakhomo, kumanja - kumanzere, titachotsa mapepalawo kuchokera pa mbale pafupi ndi khoma. Mapepala a gypsum amathandizidwa ndi zikopa zokhazokha, zomangidwe ndi khunyu, ndi gulu lapadera, lomwe limagwiritsidwa ntchito ngati kayendetsedwe ka mawonekedwe a phokoso padziko lonse lapansi. Kukonzekera kolondola kwa slabs ndi kulimbitsa kwakukulu ndizo zigawo zikuluzikulu zazodalirika zowuma. Potsirizira pake, timachotsa kuchuluka kwa mkanda wodula ndi mpweya wa mpweya.
Nthawi yokhala ndi zowuma zowonjezera kusiyana ndi kukhazikitsa konkire, mungathe kusokoneza njirayi nthawi iliyonse, ndipo zosavuta zikhoza kukonzedwa mosavuta pa gawo lililonse la ntchitoyo. Ndi zina zonse, pansi, poyikidwa ndi zowuma, sizidzatengera mtundu wake wa konkire.
