Udonga lwamakhethini luvula

Kukho iimeko ezintathu ezisisiseko ezikhokelela ekuboneni kunye nokuvuza kodonga lwamakhethini: ubukho bemibhobho; Ubukho bamanzi; Kukho umahluko woxinzelelo kunye nokuqhekeka kwe-seepage. Ukuphelisa enye okanye ngaphezulu kwezi meko zisisiseko yindlela yokuthintela ukuvuza kwamanzi: enye kukunciphisa i-porosity; Okwesibini, gcina imvula, ukuze ingasiniki isikhewu kangangoko kunokwenzeka; Okwesithathu kukunciphisa umahluko woxinzelelo lomoya kwisithuba esimanzi. (1) Vula umngxuma omncinane kumkhusane weprofayile yealuminiyam ukuya ngaphandle, qokelela kwaye ukhuphe amanzi ngaphakathi kodonga lomkhusane ngomsantsa omncinci, kwaye ukhuphe amanzi amancinci kumngxuma ocinezelayo phakathi kweglasi, iprofayili ye-aluminium. kunye nentsimbi ye-aluminium. (2) Kuyilo lwamakhethini anamhlanje, imibhobho yokuqokelela kunye nemibhobho yokuhambisa amanzi inokuqwalaselwa kwakhona kudonga lweglasi lomkhusane. Amanzi angena kwiintanda kwaye angene ngaphakathi kwodonga lwamakhethini aqokelelwa kunye kwaye akhutshwe kumngxuma ocacileyo wangaphakathi wokukhupha amanzi ngokufanelekileyo ngombhobho wokuhambisa amanzi. Ukukhethwa komgangatho ophezulu wesakhiwo se-silicone sealant, i-silicone echasene nemozulu ye-silicone sealant, iglue eludongeni, kunye nokomeleza ukuhlolwa, ukukhusela ukusetyenziswa okuphelelwe yisikhathi. Khetha umgangatho ophezulu weglasi edadayo, iglasi kufuneka icutshungulwe ngomphetho, impazamo yobungakanani beglasi ngokuhambelana neemfuno eziqhelekileyo. (4) Nika ingqalelo kulawulo lokusetyenziswa kwendawo etywiniweyo, kuthintelwe ngokungqongqo kwimozulu echasene nokwakhiwa kwe-silicone sealant kwindawo evulekileyo ngeentsuku zemvula. Iqondo lokushisa langaphakathi akufanele libe ngaphezu kwama-27 degrees, kwaye umswakama ohambelanayo akufanele ube ngaphantsi kwama-50%. Susa uthuli, igrisi, imathiriyeli ekhululekileyo kunye nobunye ubumdaka kwisakhelo sealuminiyam, ifestile yeglasi yomkhusane okanye isithuba phambi kokutofa kweglu. Emva kwesitofu seglu, kufuneka ipakishwe ngokuqinileyo, umphezulu ogudileyo, yomeleza ukugcinwa, ukuthintela ukungunda kwesandla, amanzi, njalo njalo. ukulungisa, ukulawula umgangatho wodonga lwamakhethini. Ukuhlolwa komgangatho wodonga lwamakhethini eglasi, ukwamkelwa okufihliweyo kunye nokwamkelwa kobunjineli bamacandelo amabini, ukwamkelwa okufihliweyo kuqhutyelwa emva kokufakwa kwesakhelo se-aluminium, ngokukodwa ukukhangela ukuqina kwekhowudi yentsimbi yokudibanisa, khangela udonga lwamakhethini kunye nesakhiwo esiyintloko se-aluminium. ukufakwa kwe-gap node, ukufakwa kwe-joint joint. Ukwamkelwa kweprojekthi kuya kwenziwa emva kokugqitywa kweprojekthi yodonga lwamakhethini eglasi.
