Isishwankathelo seRebar
Le ntsimbi iguqukileyo yintsimbi eqhelekileyo yokuqinisa/ esetyenziswa kwikhonkrithi eqinisiweyo kunye nezakhiwo zomatshe eziqinisiweyo. Yenziwe ngentsimbi ethambileyo kwaye inikwe iimbambo zokunamathela ngcono kwikhonkrithi. Ukuguqulwa kwembambo ngenxa yendima yembambo, kunye nekhonkrithi zinamandla amakhulu okubopha, anokumelana ngcono namandla angaphandle. Ibha yentsimbi eguqukileyo yintonga yesinyithi, ibha yentsimbi eqinisiweyo enokudityaniswa, kwaye ingasetyenziselwa ne-meshes yentsimbi. Imilo yembambo ezinqamlezileyo yi-spiral, herringbone, imilo emithathu ye-crescent. Ububanzi obuqhelekileyo bebha yentsimbi eqinisiweyo eguquliweyo buhambelana nobubanzi obuqhelekileyo bebha ejikelezayo yecandelo elilinganayo. Ikhonkrithi eqinisiweyo kwingcinezelo ephambili yokuxinana.

Iintlobo zeeRebars
Ngokuxhomekeke kuhlobo lwezinto ezisetyenzisiweyo ekuvelisweni kwee-rebar, iintlobo ezahlukeneyo zee-rebar ziyahluka.
l 1. I-European Rebar
I-European rebar yenziwe nge-manganese, eyenza ukuba zigobe lula. Azifanelekanga ukusetyenziswa kwiindawo ezichaphazeleka ziimeko zemozulu ezimbi kakhulu okanye iziphumo zejoloji, ezifana neenyikima, iinkanyamba, okanye iinkanyamba. Ixabiso lale rebar liphantsi.
l 2. I-Rebar yentsimbi yekhabhoni
Njengoko igama limele, yenziwe ngentsimbi yekhabhoni kwaye yaziwa ngokuba yiBlack Bar ngenxa yombala wekhabhoni. Eyona nto imbi ngale rebar kukuba iyagqwala, nto leyo echaphazela kakubi ikhonkrithi kunye nesakhiwo. Umlinganiselo wamandla okutsalwa kunye nexabiso lenza i-black rebar ibe yenye yezona ndlela zilungileyo zokukhetha.
l 3. I-Rebar ene-Epoxy-Coated
I-rebar ene-epoxy-coated yi-black rebar ene-epoxy coat. Inamandla afanayo okutsalwa, kodwa iyakwazi ukumelana nokugqwala ngokuphindwe kayi-70 ukuya kwi-1,700. Nangona kunjalo, i-epoxy coating ibuthathaka kakhulu. Okukhona umonakalo umkhulu kwi-coating, kokukhona ingamelani nokugqwala.
l 4. I-Galvanized Rebar
I-rebar ye-galvanized inamandla okuxhathisa umhlwa ngokuphindwe kangamashumi amane kuphela kune-black rebar, kodwa kunzima ngakumbi ukonakalisa i-coating ye-galvanized rebar. Ngaloo ndlela, inexabiso elingaphezulu kune-epoxy-coated rebar. Nangona kunjalo, ibiza malunga nama-40% kune-epoxy-coated rebar.
l 5. I-Glass-Fiber-Reinforced-Polymer (GFRP)
I-GFRP yenziwe ngefayibha yekhabhoni. Njengoko yenziwe ngefayibha, ukugoba akuvumelekanga. Ayimelani nokugqwala kwaye ibiza kakhulu xa ithelekiswa nezinye ii-rebar.
l 6. I-Rebar yentsimbi engagqwaliyo
I-stainless steel rebar yeyona bar yokuqinisa ebiza kakhulu ekhoyo, malunga nexabiso eliphindwe kasibhozo kune-epoxy-coated rebar. Ikwayeyona rebar ilungileyo ekhoyo kwiiprojekthi ezininzi. Nangona kunjalo, ukusebenzisa intsimbi engagqwaliyo kuzo zonke iimeko ngaphandle kwezona zikhethekileyo kudla ngokuba yinto egqithisileyo. Kodwa, kwabo banesizathu sokuyisebenzisa, i-stainless steel rebar inokumelana nokugqwala ngokuphindwe kayi-1,500 kune-black bar; inokumelana nomonakalo ngaphezu kwezinye iintlobo okanye i-rebar enokumelana nokugqwala okanye enganyangekiyo; kwaye inokugotywa ebaleni.
