Ubukhulu: 6-40mm
Inqubo: I-Hot Rolled, i-Ribbed, eyindilinga, alloy
I-rebar yigama elivamile lemigoqo yensimbi evuthayo evuthayo. Ibanga lebha yensimbi ejwayelekile eshisayo liqukethe i-HRB kanye nephuzu lesivuno esincane sebanga. H, r, futhi b bashisa, bavutha, nemithi ngokulandelana.
Kunezindlela ezimbili ezisetshenziswayo ezisetshenziswayo ze-rebar: eyodwa ukuhlukanisa ngesimo sejometri, nokuhlukanisa noma ukuthayipha ngokuya ngesigaba sesigaba sezimbambo eziguqukayo kanye nezikhala zezimbali. Uhlobo II. Lokhu kuhlukaniswa ikakhulukazi kukhombisa ukusebenza kokuqina kwe-rebar. Okwesibili kususelwa ekuhlukanisweni kokusebenza (ibanga), njengezinga lezwe lami lamanje lokuqalisa ukusebenza, i-rebar yi (GB1499.2-2007), ngokuya ngamandla okuqinisa (Amandla okuvuthwa / ama-Tensile) iRebar ihlukaniswe ngamamaki ama-3; Ezindaweni ezijwayelekile zezimboni zaseJapan (Ji SG3112), i-rebar ihlukaniswe ngezinhlobo ezi-5 ngokuya ngokusebenza okuphelele; EBritish Standard (BS4461), amamaki amaningana okuhlolwa kokusebenza kabusha kokuphikiswa nawo achaziwe. Ngaphezu kwalokho, ama-rewars nawo angahlukaniswa ngokuya ngokusetshenziswa kwawo, njengemigoqo yensimbi ejwayelekile yokufaka ukhonkolo oqinisiwe kanye nokushisa kwensimbi ngokhonkolo okuqiniswe ngaphambi kokuvinjelwa.
Ubukhulu
1) Ububanzi be-Microsonal ububanzi kanye nobubanzi obunconyiwe
Ububanzi bemigoqo yensimbi buqala ukusuka ku-6 kuye kwangama-50mm, futhi okujwayelekile kunconywe ama-diameters ama-radinal amabha ensimbi angama-6, 8, 10, 20, 14, 16, no-50mm.
2) ukuphambuka okuvumelekile kwesimo sobuso nosayizi webha yensimbi ehlanganisiwe
Imigomo yokuqamba yezimbambo eziguqukayo zemigoqo yensimbi enemibala izohlangabezana nalezi zidingo ezilandelayo:
I-angle Β phakathi kwembobo eguqukayo kanye ne-axis yebha yensimbi akufanele ibe ngaphansi kwama-degree angama-45. Lapho i-angle efakiwe ayikho ngaphezu kwama-degree angama-70, ukuqondiswa kwezimbambo eziguqukayo ezinhlangothini eziphambene zebha yensimbi kufanele ziphaphamele;
I-spaceding ye-auminal l yezimbambo eziguqukayo ngeke ibe zikhulu kunezikhathi ezingama-0.7 ubukhulu bebha yensimbi;
I-angle α phakathi kohlangothi lwembozo eguqukayo kanti ingaphezulu lebha lensimbi ngeke libe ngaphansi kwama-degree angama-45;
Isamba sezikhala (kufaka phakathi ububanzi bezimbambo ezinhle) phakathi kwezimbambo zezinhlangothi ezimbili ezisezinhlangothini ezimbili eziseduze kwebha yensimbi ngeke kube ngaphezulu kwe-perimeter yensimbi;
Lapho ububanzi bemfihlo bebha yensimbi bungabi ngaphezu kwe-12mm, indawo ehlobene ne-Rib akufanele ibe ngaphansi kuka-0,055; Lapho ububanzi bemizinalo bungu-14mm no-16mm, indawo ehlobene neRib akufanele ibe ngaphansi kuka-0.060; Lapho ububanzi bemiqalo bukhulu kune-16mm, indawo yeRib ehlobene akufanele ibe ngaphansi kuka-0.065. Bheka isithasiselo C esifundeni sendawo yeRib.
Imigoqo yensimbi ehlanganisiwe imvamisa inezimbambo ezinde, kepha futhi ngaphandle kwezimbambo ezinde;
3) ubude nokuvunyelwa okuvumelekile
a. Ubude
Amabha ensimbi avame ukulethwa ngobude obuhleliwe, futhi ubude obuthile bokulethwa kufanele bukhonjiswe kwinkontileka;
Amabha aqinisiwe angahanjiswa ngamakhoyili, futhi i-reel ngayinye kufanele ibe yiRebar eyodwa, ivumela u-5% wenani lama-reels e-batch ngayinye (ama-reels amabili uma ngaphansi kwamabili) aqukethe ama-restar amabili Isisindo se-disk kanye ne-disk ububanzi banqunywa ngokuxoxisana phakathi komphakeli nomthengi.
B, ukubekezelela ubude
Ukuphambuka okuvumelekile kobude bebha yensimbi lapho kuhanjiswa kubude obuhleliwe ngeke kube nkulu kune- ± 25mm;
Lapho ubude obuncane budingeka, ukuphambuka kwalo kungukuthi u-50mm;
Lapho ubude obukhulu budingeka, ukuphambuka kungu -50mm.
C, curvature futhi uyaphela
Ukuphela kwebha yensimbi kufanele kuqondiswe iqonde, futhi ukuguquguquka kwendawo akufanele kuthinte ukusetshenziswa
