Iintlobo zeeNgxube zeekhonkco kunye nokubeka iingcebiso

Izalathisi ezisetyenziselwa ukuhlawulela xa ikhonkrithi ikhula okanye iyancipha neenguqu zokushisa. Izixube zekhonkrithi ziqhelekileyo zisetyenziselwa ukukhusela iintambo xa ikhonkrithi iyancipha ngokudala, ukusetyenziswa kwezixhobo, ukukwazisa nokubeka amafomathi ahlangeneyo. Izicwangciso eziphambili ziza kubonelela ngokugqithiseleyo umkhiqizo wekhonkrithi kwaye ziya kubakho kwiindawo ezithile apho ezo ntlukwano zingaqwalaselwa khona. Ngamanye amaxesha ngenxa yezinto eziphathekayo kunye nobubanzi okanye ububanzi beekhonkrithi zekhonkco kuyadingeka ukuba kuphuculwe ukusebenza kwezinto eziphathekayo kwaye vumela izinto ukuba zandise / zenze isivumelwano okanye zihambe ngaphandle kokulimaza ezinye izakhiwo.

Iintlobo zokuBambisana

Injongo yokudala indawo ebuthathaka kwikhonkrit kwaye ilawule apho kuya kuvela khona ukuqhuba, ngokuqhelekileyo kumgca ochanekileyo. Amaqumrhu okuqhawulwa kufuneka abekwe ukuvelisa iipaneli ezikrelekrele kwaye zize zigqithise ubude obude ububanzi be-1 ½ ukuya ku-1. Izixube zivame ukuhlukaniswa kumgama olingana namaxesha angama-24 ukuya kuma-30 ngama-slab thickness.

Ulwahlulo oluhlangeneyo olungaphezulu kweenyawo ezili-15 ludinga ukusetyenziswa kwezixhobo zokudlulisa imithwalo. Izihlanganisi zokuqhawulwa zingafakwa kwi-konkrit surface ngexesha lokubekwa. Iimbumbano zinokufakwa kwi- concrete ebomini. Kubalulekile ukuqonda ukuba ukubonwa kwexesha elide kulibazisekile ukuphakama kwamathuba okuqhawula ukuzakhela phambi kokuba u-sawing uqedele.

Izithako zokwandisa

Iimboniselo zokwandiswa kweekreta zisetyenziselwa ukwahlula i-slabs kunye nekhonkrithi kwezinye iindawo zesakhiwo. Amanyathelo okwandisa avumela ukunyakaza okuzimeleyo phakathi kwamalungu alungelelaniso ekunciphiseni ukunyanzelisa xa ukunyuka okunjalo kugcinwa.

Oku kuvumela ukunyusa okutshatyalaliswayo kunye nokuqhekeka ngaphandle kokunciphisa uxinzelelo kwiinkqubo.

Kutheni sifuna amaZakhiwo ezakhiwo?

Amanyathelo okwakhiwa asetyenziswa kwiimeko apho kukho ukuhlanganiswa kwezikhonkco ezimbini. Amalungu omsebenzi avame ukufakwa ekupheleni kosuku okanye afakwe xa i- konkrit pour etyelwe ixesha elide kunexesha lokuqala lokukhonkta.

Amanyathelo wokwakha kufuneka ayenzelwe kwaye achazwe ngumyili wezakhiwo. Ungaphumelela ukubophelela kunye nokuqhubeka nokuqiniswa ngokubambisana kwezakhiwo. Ukuba iPCC eyaneleyo iyatholakala ekupheleni kosuku, iqhagamshelo lokwakha lingafakwa kwindawo ehleliweyo yokudibanisa.

Izikhonkwane zeekhonkrithi Ukubeka iingcebiso

Ezi ngcebiso ezilandelayo zicetywayo maziqwalaselwe:

• Isikhundla esiphatheleneyo sobume kufuneka sibe ngamaxesha angama-24 ukuya kuma-36 ubukhulu be-slab.
• Amajoyina kufuneka athathwe malunga neenyawo ezili-10 kunye neenyawo ezili-15.
• Xa usebenzisa i-groove edibeneyo yokudibanisa i-joints, idibeneyo kufuneka ibe ubuncinane ubuncinane be-¼ ubukhulu be-slab.
• Amanqwanqwanqwana adibeneyo ayenziwe kufuneka ayenziwe ngeeyure ezingama-4 ukuya kwe-12 emva kokuba ikhonkrit igqityiwe.
• Amalungu angama-Keyed ayanconywa kwizitektri zeplastiki.
• Amalungu amanxeba aqingqiweyo kufuneka ayenziwe phakathi kweeyure eziyi-1 ukuya kwi-4 emva kokugqitywa kokugqiba.
• I-fill filler ene-pre-molded should be used to differentiate slabs kwizakhiwo zakhiwo okanye ngeenyawo. Beka ii-intshi ezimbini zesanti ngaphaya kwe-footing ukukhusela ubophelelo kwi-footing.
• Ukuba i-slab iqulethe intambo yocingo iyanconywa ukuba iphele i-mesh kuma-joints of contraction.
• Ukwahlula okudibeneyo kufuneka kukhethwe ukwenzela ukuba izigaba zekhonkrithi ziba malunga ne square.

• Kunconywa ukuba ube namajoyina ekhonkco kunye nemigca yekholomu okanye i-sawed okanye i-keyed.
• Amanxiwa ensimbi kufuneka asetyenziswe kuma-slabs athatha imithwalo enzima.
• Cwangcisa indawo efanelekileyo kuzo zonke izihlanganisi ezibandakanya ixesha lokusika.
• Sebenzisa amanqanaba okuhlukanisa phakathi kwe-slabs kunye neentsika, izindonga kunye neenyawo kunye nalapho iingcambu okanye iindlela zokuhamba zidibana nezinye izakhiwo zekhonkrithi.
• Izixhobo ezisetyenziselwa amajoyina ekhonkco kufuneka zitshintshwe ngokwaneleyo ukuze zithinte okanye zitshintshe njengoko zifunekayo kwaye zikwazi ukubuyisela kwiindawo zazo zangaphambili.
• Hlalani nibheka izinto eziphathekayo kwaye ziyakwazi ukukhonkxa kwikhonkrithi.

Izixhobo ezisetyenziselwa ukudala ii Joint Concrete Joints

Ezi zixhobo zilandelayo zisetyenziselwa ukudala izihlanganisi zekhonkrithi, nangona ezi zixhobo zingahluka ngokuxhomekeka kubukhulu kunye nobubanzi beprojekthi. Nazi izixhobo eziqhelekileyo ezisetyenziswayo:

• I-Grover Hand okanye i-Walking Grover: Ngokuxhomekeka kwindlela enkulu ngayo i-slab, unokufuna ukukhetha enye yezi zimbini.

• Izixhobo ezihlangeneyo zokulawula: ezilungele ukusetshenziswa kwiiprojekthi ezincinci eziphakathi.
• Ikhonkrithi yabona: ilungele ukubonwa kwekhonkrit, kodwa qiniseka ukuba uyazi ukuba kunzulu kangakanani, kufuneka udale ezinye iingxaki.
