Isingeniso ekusetshenzisweni kwe-rebar

I-Rebar: “Amathambo nemisipha” kumaphrojekthi okwakha

I-Rebar, igama layo eliphelele elithi “i-hot-rolled ribbed steel bar”, iqanjwe ngenxa yezimbambo ezisatshalaliswe ngokulinganayo ngobude bobuso bayo. Lezi zimbambo zingathuthukisa isibopho phakathi kwe-steel bar kanye nekhonkrithi, okuvumela ukuthi zombili zakhe into eqinile futhi zimelane namandla angaphandle ngokubambisana. Njengezinto ezibalulekile ezibalulekile kumaphrojekthi okwakha, i-rebar isetshenziswa kabanzi futhi ibalulekile, futhi idlula cishe kuzo zonke izixhumanisi kusukela kwingqalasizinda kuya ezakhiweni eziphakeme.

Insimu yokwakha izindlu

Ezakhiweni zomphakathi nezentengiselwano, i-rebar ifana “ne-skeleton”.

• Isisekelo kanye nemishayo: Isisekelo, amakholomu athwala imithwalo, imishayo kanye nezinye izakhiwo eziyinhloko zendlu zidinga i-rebar ukuze zakhe uhlaka lwensimbi bese zithela ukhonkolo. Isibonelo, izindonga zokusika kanye nezinsika zohlaka lwezakhiwo zokuhlala eziphakeme kumele zithembele emandleni aphezulu e-rebar ukuze zimelane nesisindo sesakhiwo ngokwaso kanye nemithwalo yangaphandle ukuze kuvinjelwe ukuguquka kwesakhiwo noma ukuwa.

• Iphansi nodonga: I-mesh yensimbi phansi kanye nezinsika zesakhiwo odongeni nazo zenziwe nge-rebar. Ingasabalalisa ingcindezi phansi, inciphise ukuqhekeka, futhi ithuthukise ubuqotho kanye nokumelana nokuzamazama komhlaba kodonga.

Ukwakhiwa kwengqalasizinda

• Ubunjiniyela bebhuloho: Kungakhathaliseki ukuthi ibhuloho lomgwaqo omkhulu, ibhuloho lesitimela noma ibhuloho elidlulayo, i-rebar isetshenziswa kabanzi ezingxenyeni ezibalulekile njengezinsika zebhuloho, amadekhi ebhuloho, kanye nemishayo ethwala umthwalo. Uma ibhekene nemiphumela ephindaphindayo yokugingqika kwezimoto, isisindo esibi kanye nendawo yemvelo (njengokushintsha komoya kanye nokushisa), i-rebar inikeza ukumelana okwanele kokucindezelwa nokucindezela kwamabhuloho, okuqinisekisa ukuzinza nokuphila kwenkonzo yamabhuloho.

• Ukuthuthwa komgwaqo nowesitimela: Ekuqinisweni komgwaqo kwemigwaqo emikhulu kanye nesakhiwo esisekelayo semizila yesitimela esingaphansi komhlaba, i-rebar ivame ukusetshenziselwa ukwenza izingxenye zekhonkrithi eziqinisiwe ukuze kuthuthukiswe amandla okuthwala imigwaqo nemizila ukuze kubhekane nemithwalo yezimoto evame ukwenzeka.

• Amaphrojekthi okonga amanzi: Izindawo zokonga amanzi ezifana namadamu okugcina amanzi, iziteshi zokuphambukisa amanzi, kanye nama-culvert zithinteka isikhathi eside futhi zicindezelwe amanzi. Uhlaka lwensimbi olwenziwe nge-rebar lungathuthukisa kakhulu ukumelana nokuqhekeka kwezakhiwo zekhonkrithi nokuqina, kuqinisekiswe ukusebenza okuphephile kwamaphrojekthi okonga amanzi.

Ubunjiniyela bezimboni kanye nobukhethekile

I-Rebar nayo idlala indima ebalulekile ezitshalweni zezimboni, ezindaweni zokugcina impahla, kanye nasezisekelweni zemishini emikhulu. Isibonelo, isisekelo semishini sesitshalo semishini esindayo sidinga ukumelana nesisindo esikhulu semishini kanye nokudlidliza ngesikhathi sokusebenza. Ukuhlanganiswa kwe-rebar kanye nokhonkolo kunganikeza amandla aqinile esakhiwo ukugwema ukuhlaliswa kwesisekelo noma umonakalo. Ngaphezu kwalokho, kwamanye amaphrojekthi akhethekile njengezitshalo zamandla enuzi kanye nezindawo zokugcina ichweba, i-rebar idinga ukuhlangabezana nezidingo zamandla aphezulu kanye nokumelana nokugqwala ukuze ivumelane nezinselele zezindawo ezikhethekile.

Ngamafuphi, i-rebar, enezakhiwo zayo ezinhle kakhulu zemishini kanye nokusebenzisana okuhle nokhonkolo, isibe “ithambo” lokuqinisekisa ukuphepha kwesakhiwo kumaphrojekthi okwakha esimanje, isekela zonke izinhlobo zezakhiwo kusukela emidwebweni yokuklama kuya kwengokoqobo.
