Kunezindlela ezimbili ezivame ukusetshenziswa zokuhlukanisa ze-rebar: eyodwa iwukuhlukanisa ngokuma kwejiyomethri, nokuhlukanisa noma uthayiphe ngokuya ngokuma kwesigaba esiphambanayo sombambo oguquguqukayo kanye nokuhlukana kwezimbambo.Uhlobo II.Lokhu kuhlukaniswa kukhombisa ngokuyinhloko ukusebenza okubambekayo kwe-rebar.Okwesibili kusekelwe ekuhlukaniseni ukusebenza (ibanga), njengezinga lezwe lami lokusebenza lamanje, i-rebar ithi (GB1499.2-2007) intambo ingu-1499.1-2008), ngokuya ngeleveli yamandla (iphuzu lokukhipha/amandla okubamba) I-rebar ithi ihlukaniswe ngamabanga ama-3;ku-Japan Industrial Standard (JI SG3112), i-rebar ihlukaniswe yaba izinhlobo ezi-5 ngokuya ngokusebenza okuphelele;ku-British Standard (BS4461), amamaki ambalwa okuhlolwa kokusebenza kwe-rebar nawo acacisiwe.Ngaphezu kwalokho, ama-rebar angabuye ahlukaniswe ngokuya ngokusetshenziswa kwawo, njengemigoqo yensimbi evamile yokhonkolo oqinisiwe kanye nezinsimbi zensimbi eziphathwa ngokushisa zokhonkolo oqinisiwe oqinisiwe.
I-Rebar iyibha yensimbi enezimbambo ngaphezulu, eyaziwa nangokuthi ibha yensimbi eyi-ribbed, ngokuvamile enezimbambo ezi-2 longitudinal nezimbambo eziphambanayo ezisatshalaliswe ngokulinganayo ohlangothini lobude.Ukuma kobambo oluphambanayo ku-spiral, herringbone kanye ne-crescent shape.Kuvezwe ngamamilimitha obubanzi obujwayelekile.Ububanzi obuncane bebha elinezimbambo buhambisana nobubanzi obungajwayelekile bebha eyindilinga yesigaba esiphambene esilinganayo.Ububanzi obujwayelekile be-rebar bungu-8-50 mm, futhi ububanzi obunconywayo bungu-8, 12, 16, 20, 25, 32, kanye no-40 mm.Imigoqo yensimbi enezimbambo ikakhulukazi ingaphansi kwengcindezi eqinile kukhonkolo.Ngenxa yesenzo sezimbambo, imigoqo yensimbi enezimbambo inekhono elikhulu lokubopha ngokhonkolo, ukuze ikwazi ukumelana kangcono nesenzo samandla angaphandle.Imigoqo yensimbi enezimbambo isetshenziswa kabanzi ezakhiweni ezihlukahlukene zokwakha, ikakhulukazi ezinkulu, ezisindayo, ezilula ezinodonga oluncane oluncane kanye nezakhiwo zokwakha eziphakeme.
I-Rebar ikhiqizwa izigayo ezincane ezigoqayo, futhi izinhlobo eziyinhloko zezigayo ezincane ezigoqayo yilezi: eziqhubekayo, eziqhubekayo kanye ne-tandem.Iningi lezigayo ezintsha nezisetshenziswayo ezincane emhlabeni zisaqhubeka ngokugcwele.Izigayo ze-rebar ezidumile ziyizigayo ze-rebar zenhloso ezijwayelekile ezinesivinini esiphezulu kanye nezigayo ze-rebar ezikhiqiza kakhulu eziyisi-4.
I-billet esetshenziswa kumshini wokugaya omncane oqhubekayo ngokuvamile i-billet yokuphonsa eqhubekayo, ubude obuhlangothini ngokuvamile buba ngu-130 ~ 160mm, ubude ngokuvamile buba ngamamitha angu-6~12, kanti isisindo se-billet esisodwa singamathani angu-1.5~3.Iningi lemigqa egoqayo ihlelwa ngokushintshana ngokuvundlile nangokuqondile, ukuze kuzuzwe ukugoqeka okungagungxuki emugqeni.Ngokwezigayo ezihlukene ze-billet kanye nosayizi bomkhiqizo oqediwe, kukhona izigayo ezincane eziyi-18, 20, 22, nezingu-24, kanti eziyi-18 ziyi-mainstream.Ukugingqika kwebha ngokuvamile kusebenzisa izinqubo ezintsha ezifana nezitebhisi zokushisa, ukwehla kwamanzi anomfutho ophezulu, ukuginqika okunokushisa okuphansi, nokuginqika okungapheli.Ukugingqika okungalungile kanye nokuginqika okuphakathi kuyathuthukiswa ukuze kuhambisane namabhilidi amakhulu futhi kuthuthukiswe ukunemba kokugoqa.Izigayo zokuphothula ikakhulukazi Ukunemba Okuthuthukisiwe kanye nesivinini (kufika ku-18m/s).Imininingwane yomkhiqizo imvamisa ingu-ф10-40mm, futhi kukhona no-ф6-32mm noma ф12-50mm.Amamaki ensimbi akhiqizwayo ayinsimbi ephansi, ephakathi nendawo ephezulu kanye nensimbi ye-alloy ephansi edingeka kakhulu emakethe;isivinini esikhulu sokuginqika ngu-18m/s.Inqubo yayo yokukhiqiza imi kanje:
