I-Rebar, edla ngokubizwa ngokuba yi-i-rebar, idlala indima ebalulekileyo ekwakheni, inika amandla okutyhafa afunekayo ukuxhasa izakhiwo zekhonkrithi. Uhlobo lwentsimbi olukhethiweyo kwiprojekthi ludla ngokuxhomekeka kudidi lwayo lwamandla kunye nokusetyenziswa kwayo okuthile, ngoko ke iinjineli kunye nabakhi kufuneka bazi ngezi zinto.
Kukho iintlobo ezininzi ze-rebar, nganye yenzelwe usetyenziso oluthile. Ezona ntlobo zixhaphakileyo ziquka:
1. I-rebar yentsimbi ethambileyo(Udidi lwama-40): Olu hlobo lunamandla okuvelisa angama-40,000 psi kwaye lusetyenziswa kakhulu kwiiprojekthi zokuhlala ezifana neendlela zokungena kunye neendlela zokuhamba ngeenyawo. Ukuguquguquka kwalo kwenza kube lula ukugoba nokuyila.
2. Intsimbi enamandla aphezulu(Ibanga lama-60): Le bar yentsimbi inamandla okuvelisa angama-60,000 psi kwaye ifanelekile kwizicelo zorhwebo nezoshishino, kuquka izakhiwo ezinde kunye neeBridges. Ukonyuka kwamandla ayo kunokunciphisa ukusetyenziswa kwezinto ngaphandle kokuchaphazela ukuthembeka kwesakhiwo.
3. I-rebar ene-epoxy-coated: Olu hlobo lugqunywe nge-epoxy ukuze lungagqwali, nto leyo eyenza ukuba lufaneleke kwizakhiwo ezichaphazeleka kwiindawo ezinobungozi, ezifana nokusetyenziswa kweMarine okanye kwiindawo ezinomswakama ophezulu.
4. I-rebar yentsimbi engenasici: I-rebar yentsimbi engagqwaliyo yaziwa ngokumelana kwayo nokugqwala okuphezulu kwaye isetyenziswa kwiindawo ezinokugqwala okuphezulu ezifana nezityalo zeekhemikhali kunye nezakhiwo zaselunxwemeni.
Inqanaba lobunzulu kunye nokubaluleka kwalo:
Umgangatho wamandla we-rebar yeyona nto ibalulekileyo ekumiseleni umthamo wayo wokuthwala. Umgangatho ophezulu, njengomgangatho wama-75 okanye wama-80, unika amandla aphezulu okutsalwa, okwenza ukuba ifaneleke ukusetyenziswa kwimisebenzi enzima. Ukukhethwa komgangatho wamandla kuchaphazela ngqo uyilo kunye nokhuseleko lwesakhiwo kuba kuchaphazela ubungakanani bomthwalo onokuxhaswa ziibha zentsimbi.
Ukuqukumbela, ukuqonda iintlobo ezahlukeneyo zee-rebar kunye namanqanaba azo okuqina ahambelanayo kubalulekile ekukhetheni izinto ezifanelekileyo kuyo nayiphi na iprojekthi yokwakha. Ngokuqwalasela ukusetyenziswa okuthile kunye neemeko zokusingqongileyo, abakhi banokuqinisekisa ubomi benkonzo kunye nokhuseleko lwezakhiwo zabo.
