Funda indlela yokuTuckpoint

I-Tuckpointing iyigama elisetyenziselwa ukuchaza inkqubo yokususa amanxuwa angcolileyo. Amanqaku omzimba anqunywe kwizinga eliphezulu kwaye azalise umquba omtsha. I-Tuckpointing ibuye ibhekiswe njengeyokukhomba kunye nokuphindaphinda, nangona kunjalo, kusenokuthetha ukubeka iplastiki kwindonga zokuqhawula ngaphandle kokukhipha umdaka owenziwe ekuqaleni.

Ukuhlanganiswa okudala akufuneki ukulungiswa, iindonga ezitsha nazo zifuna ukuba zilungiswe ukulungiswa kokungena kumdaka, okanye xa idibeneyo ingagqibekanga.

Ukulungiselela

I-Tuckpointing ingaba yinkqubo enzima yomsebenzi kwaye kufuneka yenziwe ngumasoni onamava okanye umntu onamava afanelekileyo. Uhlolo olupheleleyo lweengxaki kufuneka lwenziwe phambi kwenkqubo yokwenza i-tuckpointing procedure, ukuchonga ukuba ingaba zonke izihlanganisi zomdaka zifuna ukubuyiswa, okanye ngaba ngumsebenzi kuphela ohambelana nendawo apho idibaniselwano lomdaka sele liphumelele.

Ummiselo wokugqibela kufuneka uqwalaselwe ukuba isakhiwo esipheleleyo sifanele sihlambuluke, iimeko ezidibeneyo zomdongwe, ubudala bendawo, kunye nohlobo lomdaka olulungiswayo okanye ukwakhiwa kwembali okanye kwangoko. Unako ukukhenkceza umdibaniselwano ococekileyo okanye usebenzise i-drill power and wheel-cut cutting wheel ukuze unqumle umquba.

Inkqubo yokuxuba

Ukukhutshwa kwezinto ezidlulileyo kumdaka omdala ngaphandle kwePortland samente kungakhokelela ekutshitsheni kweeyunithi zamatye. Kwiminyaka emashumi eyadlulayo, umdaka waxutywa kunye nezinto ezingavamile ukunika ukuhluka okungafaniyo kunye nombala ongaqhelekanga wombala.

Landela la ma nyathelo alula kwinkqubo enobuncwane.

1. Nquma ukuba izixhobo zamandla ziya kusetyenziswa. Ukubona kunye nokugaya kusetyenziswa ngokuqhelekileyo ukususa umdaka omdala.
2. Ukuba izixhobo zomatshini ziya kusetshenziselwa, kukhuseleko olongezelelweyo kuyadingeka ukuba ugweme ukulimaza iiyunithi zobumbano.
3. Gqoka izixhobo ezikhuselekileyo zokukhusela.

1. Susa umquba omdala kwi-intshi epheleleyo ye-3/8 intshi ukuya kwi-1/2 intshi, okanye kude kufumaneke umdaka oqinile.
2. Qaphela: Musa ukususa ngaphezu kweyesithathu ubunzulu beyunithi yombutho.
3. Susa uthuli kunye neengcola ngokuxubha, ukuhlanjululwa ngamanzi okanye ukubethelela intambo yomdaka kunye nomoya ukususa zonke iindidi ezintle.
4. Khetha uhlobo lomdaka oluya kusetyenziswa. Ingaba ngumdongwe owenziwe ngaphambili oqhelekileyo osetyenziswa ngokuqhelekileyo ukunciphisa i-shrinkage.
5. Hlanganisa izidibanisi ukufanisa imibala ekhoyo yomdaka xa kuyimfuneko.
6. Beka zonke izithako kwibhokisi yokuxuba.
7. Hlanganisa ngokupheleleyo zonke izithako.
8. Yongeza isigamu samanzi adingekayo kumxube.
9. Hlanganisa ide umdaka uvelise unobumba obuninzi, obunzima ngokwaneleyo ukwenzela ukuba ibhola ingakhiwe, ngaphandle kokuhamba kwamanzi.
10. Vumela umxube usethe kwaye u-hydrate malunga neeyure ezimbini.
11. Yongeza amanzi ukuze ukwandise ukusebenza. Nangona kunjalo ukongeza amanzi amaninzi, kuya kunciphisa ukusebenza.

Ukusebenzisa i-Mortar

• Amalungu afanelekileyo kufuneka axinzelelwe ukuba aqiniseke ukuba umxube omtsha womdaka, iibhonkco ngokwaneleyo kwizinto ezikhoyo kunye nomhlaba. Iimveliso eziliqela zifumaneka kwiimarike eziza kukuvumela ukuba ufake umquba kumalungu.
• I-Pak yomdaka ekubambisene kunye nencoko ye-trowel.
• Gcwalisa udibaniso oluvulekileyo kunye nomdaka, uze unyuke umdaka ogqithiseleyo, ngoko umdaka udibene kunye nomhlaba.

• Xa umquba uqala ukuqina, sebenzisa isilathisi esivumelwaneni sokubamba amanxeba. Qala ngamalungu angama-vertical and then joints.
• Umdaka kufuneka ubekwe kwiimitha eziyi-1/4-intshi ekumgangatho wokunciphisa iipokotshi zomoya kunye ne-voids.

Ukunyuka kwexesha xa kwenziwa ngokufanelekileyo kuya kunika umbane onamandla ongenamanzi onxulumene nombonakalo wokuqala wamanxuwa. Kuya kunceda ukunweba ubomi besakhiwo kunye nokubonelela ngokukhuseleka kwamanzi kwisakhiwo sendawo kunye nomkhiqizo ogqityiweyo ozakugqitywa.
