Ukubuka konke kweRebar
Le nsimbi egobile iyi-bar evamile yokuqinisa insimbi/ esetshenziswa kukhonkrithi eqinisiwe kanye nezakhiwo zokwakha eziqinisiwe. Yakhiwa ngensimbi ethambile futhi inikezwa izimbambo zokunamathela okungcono kukhonkrithi. Ukuguqulwa kwezimbambo ngenxa yendima yezimbambo, kanye nekhonkrithi kunekhono elikhulu lokubopha, okungamelana kangcono namandla angaphandle. I-bar yensimbi egobile iyinduku yensimbi, i-bar yensimbi eqinisiwe ethambekelekayo, futhi ingasetshenziswa futhi kuma-meshe ensimbi. Ukuma kwezimbambo eziphambeneyo kuyi-spiral, herringbone, i-crescent-shaped three. Ububanzi obujwayelekile be-bar yensimbi eqinisiwe egobile buhambisana nobubanzi obujwayelekile be-bar eyindilinga ye-cross-section efanayo. Ikhonkrithi eqinisiwe ekucindezelekeni okuyinhloko kokudonsa.

Izinhlobo ze-Rebars
Kuye ngohlobo lwezinto ezisetshenziswa ekukhiqizweni kwe-rebar, kunezinhlobo ezahlukene ze-rebar
l 1. I-European Rebar
I-rebar yaseYurophu yenziwe nge-manganese, okwenza zigobe kalula. Azifanele ukusetshenziswa ezindaweni ezivame ukuba nezimo zezulu ezimbi kakhulu noma imiphumela ye-geological, njengokuzamazama komhlaba, iziphepho, noma iziphepho. Izindleko zale rebar ziphansi.
l 2. I-Rebar yensimbi yekhabhoni
Njengoba igama limelela, yakhiwe ngensimbi yekhabhoni futhi yaziwa kakhulu ngokuthi iBlack Bar ngenxa yombala wekhabhoni. Inkinga enkulu yale rebar ukuthi iyagqwala, okulimaza ukhonkolo kanye nesakhiwo. Isilinganiso samandla okudonseka esihambisana nenani senza i-black rebar ibe ngenye yezinketho ezinhle kakhulu.
l 3. I-Rebar Embozwe Nge-Epoxy
I-rebar ene-epoxy-coated iyi-rebar emnyama ene-epoxy coat. Inamandla afanayo okubamba, kodwa imelana nokugqwala izikhathi ezingu-70 kuya ku-1,700. Kodwa-ke, i-epoxy coating ibucayi kakhulu. Uma umonakalo we-coating umkhulu, kulapho imelana nokugqwala khona kancane.
l 4. I-Galvanish Rebar
I-rebar ye-galvanized imelana nokugqwala ngokuphindwe kangamashumi amane kuphela kune-black rebar, kodwa kunzima kakhulu ukulimaza i-coating ye-galvanized rebar. Ngaleyo ndlela, inenani elikhulu kune-epoxy-coated rebar. Kodwa-ke, ibiza cishe ngo-40% kune-epoxy-coated rebar.
l 5. I-Glass-Fiber-Reinforced-Polymer (GFRP)
I-GFRP yakhiwe nge-carbon fibre. Njengoba yakhiwe nge-fibre, ukugoba akuvunyelwe. Imelana kakhulu nokugqwala futhi iyabiza uma iqhathaniswa nezinye izimbobo.
l 6. I-Rebar Yensimbi Engagqwali
I-rebar yensimbi engagqwali iyi-reinforcement bar ebiza kakhulu etholakalayo, cishe intengo yayo iphindwe kasishiyagalombili kune-rebar ene-epoxy-coated. Futhi iyi-rebar engcono kakhulu etholakalayo kumaphrojekthi amaningi. Kodwa-ke, ukusebenzisa insimbi engagqwali kuzo zonke izimo ngaphandle kwezimo ezihlukile kakhulu kuvame ukuba yinto edlulayo. Kodwa, kulabo abanesizathu sokuyisebenzisa, i-rebar yensimbi engagqwali imelana nokugqwala izikhathi ezingu-1,500 kune-black bar; imelana kakhulu nomonakalo kunanoma yiziphi ezinye izinhlobo noma i-rebar emelana nokugqwala noma evikela ukugqwala; futhi ingagobeka ensimini.
