Ukwakha isisekelo esezingeni eliphakeme futhi esihlala isikhathi eside kunoma yikuphi ukuqeda phansi, kuyadingeka ukuthola ikhono lokuthwala kwalo lonke isakhiwo.
Isisindo se-screed sikhulu ngokwanele, ngakho-ke sinengcindezi enkulu ngesisekelo sesakhiwo.
Ezimweni lapho, hhayi inhlanganisela eyenziwe ngomumo etholwe ezitolo zokwakha isetshenziselwa ukwenza umsebenzi, kepha ukwakheka okulungiselelwe ngokuzimela, ukubalwa okunembile kufanele kwenziwe kucatshangelwa izici zezinto ezisetshenzisiwe.
Ukukhetha kwezinto zokulungiswa kanye nokulungiswa kwenhlanganisela
I-CPS noma i-Cect-Sand Screedes iyindlela edingekayo futhi elula yendlela yokufinyelela ezingeni. Kudinga isihlabathi, usimende namanzi ukuwela. Inani lezakhi ngakunye lincike ezicini zabo.
Isibonelo, uma i-Conment Brand M150 ithathwa, khona-ke isihlabathi sizodingeka kathathu. Uma i-M500 Brand Cement isetshenziselwa ukulungiselela le ngxube, khona-ke isihlabathi sithathwa ngokuya ngengxenye ye-1: 5.
Esikhwameni sika-50 kg thatha isihlabathi esingu-150 kg
Ukusetshenziswa komfanekiso we-brand m 150 usimende kulungile, ngoba kwalokhu okucatshangelwe lokhu okunesisindo esingu-50 kg kuzodinga i-150 kg yesihlabathi. Ngokuqondene nenani lamanzi, kuya ngomswakama wesihlabathi.
Kungenzeka ukulungiselela isixazululo esezingeni eliphakeme ngokuthatha:
- Isikhwama esingu-1 (50 kg) usimende;
- I-15 yenqabile amabhakede (150 kg) wesihlabathi esomile;
- 27 amalitha amanzi.
Isingeniso sokwakheka kwesihlabathi esimanzi sizonciphisa umthamo wamanzi kumalitha ama-25.
Ngokwesisindo sokuthayipha kwesihlabathi sikasimende kuncike ekucindezelweni okuzoba nakho esisekelweni sesakhiwo. Ngokuvumelana nalokhu, ngaphambi kokuqhubeka nokwenza umsebenzi, kuyadingeka ukucacisa ubukhulu bengqimba yesendlalelo.
I-Screed kumele ibe yinqwaba yobukhulu okungenani abangama-30 mm
Ubukhulu obuhle obuhle bungu-0,3 cm. Ngaphandle kwalokho, ngemuva kokuthela ikhambi, ingaphezulu lihlanganisa imifantu. Ubukhulu obukhulu obukhulu obulingana no-0.5-1 cm kuholela ekutholeni umthwalo ovunyelwe esisekelweni.
Uma leli nani lifinyelela kuma-8-10 cm, isisindo sosimende Screed kumitha ngayinye yesikwele sizoba cishe ngo-150 kg. Akwamukeleki ngakho-ke ochwepheshe bancoma ukungadluli amapharamitha asethiwe.
Isihloko ngesihloko: Ungasiqeda kanjani izintuthwane ezincane ekhishini?
Ubuningi bengxube buxhomeke kwikhwalithi yezinto ezibonakalayo
Lapho udala i-Centment-Sand Screed ngosayizi we-1 cm, izinga lokugeleza lizoba okungenani ama-20 kg ngemitha yesikwele. Ngasikhathi sinye, kuzoba kusuka ngo-15 kuye ku-20 kg nge-1 cm².
Kumele kubhekwe ngesikhathi sokudalwa kwesimo sobuntu besilayi sesendelizwe, kuncike kumiphi izinto ezizokhethwa ngamakhosi.
Ngale pharamitha, izingoma zihlukaniswe:
- Ukukhanya, ubungako bakwanga ngaphezu kwe-1400 kg / m³.
- Izibopho ezinzima zikhonjiswe yinkomba yazo ephakeme kakhulu kune-1400 kg / m³.
Ngokuhambisana nobuchwepheshe obunembile ngokwengxenye yesigaxa sesimende, kuya ngesimilo sesihlabathi, ngeke kudlule imikhawulo evunyelwe.
Ngokuhambisana ne-GOST 8736-77, imitha eyodwa ye-cubic yesihlabathi akumele ibe ngaphezu kwe-1600 kg, futhi ingxenye yawo kufanele ibe ngu-1550 kuye ku-1700 kg / m³. Ngemininingwane yokuthi ungasenza kanjani isisombululo, bheka le vidiyo:
Bala ukusetshenziswa kwezinto zokwakha ngokusebenzisa ifomula nereferemu ekhona. Lapho usebenza ngomugqa kasimende m 400 ekwakhiweni kwentambo yobukhulu obungu-3 cm egumbini, indawo yayo engama-50 m², izothatha leyo nsimu enjalo, ukuthola okuzosiza okuzosiza Ukubalwa okulula:
- Bala umthamo we-screed. 50 × 0.03 = 15 m³.
- Ivolumu yengxenye ngayinye. Ngaphansi kwengxenye ye-4: 1, 15: 4 = 3.75 M³.
- Ivolumu yesihlabathi izoba ngu-3.75 × 4 = 15 m³, umthamo kasimende - 3.75 × 1 = 3.75 m³.
- Usebenzisa idatha yesethenjwa, ukubala isisindo esithile sesihlabathi - 15 × 1600 = 24000 kg, kanye nengxenye kasimende - 3.75 × 1300 = 4875kg.
Ivolumu yamanzi inqunywa ngesilinganiso samalitha ayi-0,5 nge-1 kg kasimende. Ngokuvumelana nalokhu, 4875 × 0.5 = 2437.5 kuzodingeka.
Ukuhambisana nazo zonke lezi zinkambiso kuzokuvumela ukuthi wenze umsebenzi wokuqonda futhi udale isisekelo esiqinile nesinokwethenjelwa sokuqeda ukunamathela.
Inqubo yokwenza umsebenzi
Izenzo zokuqala ziyadingeka nokulungiselela isisekelo.
Isihloko ngesihloko: Ukwakheka koqobo kwe-3-Samp ngesimo samakati noma amalambu kuyenze ngokwakho
Kulokhu, izitezi zihlanzwa kusuka kwangaphambilini, zikhulula igumbi kusuka kudoti wokwakha futhi zidalule izibani zokwakha, zinquma umkhathizwe ngezinga.
Ukuhlelwa kwesisulu se-sand-cement screen kungenzeka kunoma yiliphi igumbi, izinga lokushisa lesisekelo lapho lingaweli ngaphansi kwe- +5 ͦCelia.
Ukufaka ama-beacons, aqhubekele ekugcwalisweni kwesikrini kusuka ekhoneni elikude
Izilonda zifakwa engxenyeni eyandulelayo yokungena kwamanzi, okungasetshenziswa ifilimu ye-polyethylene. Imiphetho ye-canvas isesodongeni ukuze kwenziwe emazingeni asetshenzisiwe.
Gcwalisa i-screede kuqala ngezindawo ezinzima kakhulu ezikude, kepha uma umnyango unikezwe kuwo, kubalulekile ukwenza lokho kungavinjelwe umnyango.
Ngemuva kokuthi isixazululo silukhuni, okufakwe kuwo ama-beacons, ingxube elungiselelwe ithelelwa esisekelweni, isigcwalise ngomucu owodwa. Usebenzisa umthetho, ikhambi liqondaniswe, futhi kuphela ngemuva kokuthi umucu wokuqala uzobe usulungile, aqhubekele ekuthuleni kwesixazululo esisesibili. Ngemuva kwamahora ayi-12, izilonda ezikhanyayo ziyasuswa, indawo ephumela igcwele isisombululo esizothatha cishe amahora ayi-15 ukunwebeka okuphelele.
Manje sebelungiselela ingxube ye-grout futhi benze okukhohlisayo okuhambisana ne-grout ebusweni. Kuzothatha ingxube esomile noma emanzi equkethe izingxenye ezilinganayo zesihlabathi nososimende. Indawo yokushelela ngemishini ekhethekile noma ngesandla, usebenzisa insimu noma i-grater. Yonke imininingwane yenqubo yokugcwalisa izinhlobo kuma-beacons, bheka le vidiyo:
Ngemuva kokuphothula wonke umsebenzi, kutholakala indawo ebukekayo ebukekayo, okumele ibekwe nge-roller emanzi bese ikhava ngefilimu yepulasitiki. Manconsiza okususelwa okungenani izinsuku eziyisikhombisa, emva kwalokho ifilimu isusiwe.
