I-Rebar ligama eliqhelekileyo leentsimbi zentsimbi eziqengqelekayo.Ibakala lentsimbi yentsimbi eqhelekileyo eshushu-eqengqelekayo libandakanya iHRB kunye neyona ndawo isezantsi yesivuno somgangatho.H, R, kunye no-B ngoonobumba bokuqala besiNgesi bamagama amathathu, Hotrolled, Ribbed, and Bars, ngokulandelelanayo.Iintsimbi zetsimbi ezifakwe kwi-hot-rolled ribbed zihlukaniswe ngamabakala amathathu: i-HRB335 (ibakala elidala liyi-20MnS), i-HRB400 (ibakala elidala yi-20MnSiV, 20MnSiNb, 20Mnti) kunye ne-HRB500.
Isishwankathelo
I-fine-grained hot-rolled steel bar Ileta yokuqala yesiNgesi (Elungileyo) ye "fine" yongezwa kwigama legama lentsimbi yentsimbi eshushu.thanda:
I-HRBF335HRBF400, i-HRBF500.Amabanga asebenzayo ezakhiwo zeenyikima ezineemfuno eziphezulu ngala: yongeza u-E emva kwamabanga akhoyo (umzekelo: HRB400E
I-HRBF400E)
Usetyenziso oluphambili: lusetyenziswa ngokubanzi kulwakhiwo lobunjineli boluntu njengezindlu, iibhulorho, iindlela, njl.
Umahluko phakathi kwe-rebar kunye ne-bar engqukuva: Umahluko phakathi kwe-rebar kunye ne-bar engqukuva kukuba kukho iimbambo ze-longitudinal kunye neentambo ezinqamlezayo kumphezulu, ngokuqhelekileyo zineembambo ezimbini ze-longitudinal kunye neembambo ezinqamlezileyo zisasazwe ngokulinganayo kwicala lobude.I-Rebar yintsimbi yecandelo elincinci, elisetyenziselwa ubukhulu becala kwi-skeleton yamacandelo okwakhiwa kwekhonkrithi eyomeleziweyo.Ekusetyenzisweni, amandla athile omatshini, ukusebenza kwe-deformation yokugoba kunye nokusebenza kwe-welding kuyafuneka.Iibhilidi zezinto eziluhlaza zokuveliswa kwee-rebars ziyintsimbi ye-carbon structural okanye i-low-alloyed structure steel steel ephathwayo nge-sedation.
Insimbi yolwakhiwo, imivalo yentsimbi egqityiweyo ihanjiswa kwindawo eshushu, eqhelekileyo okanye eshushu.
uhlobo
Kukho iindlela ezimbini ezisetyenziswa ngokuqhelekileyo zokuhlelwa kwe-rebar;enye ihlelwa ngokwemilo yejometri, kwaye ihlelwa okanye ihlelwe ngokwemilo enqamlezileyo yembambo enqamlezileyo kunye nezithuba zeembambo.
Uhlobo, njengeBritish Standard (BS4449), i-rebar yahlulwe ibe |uhlobo, ndiyachwetheza.Olu lwahlulo lubonisa ubukhulu becala ukusebenza okubambekayo kwe-rebar.Zimbini
Ukuhlelwa kwentsebenzo (ibakala), njengomgangatho wokuphunyezwa ngoku welizwe lam, i-rebar yi (GB1499.2-2007) intonga yocingo yi-1499.1-2008), ngokwebakala lamandla
Ezahlukeneyo (inqaku lesivuno / amandla okuqina), i-rebar yahlulwe ngamabakala ama-3;kwiMigangatho yoShishino lwaseJapan (JISG3112), i-rebar ihlukaniswe kwiindidi ezi-5 ngokwentsebenzo ebanzi;kuMgangatho waseBrithani (BS4461), i-rebar nayo ichaziwe Amanqanaba amaninzi ovavanyo lokusebenza.Ukongeza, i-rebar inokuphinda iqhutywe ngokwesicelo.
Ukwahlula, njengemivalo yentsimbi eqhelekileyo yekhonkrithi eyomeleziweyo kunye nemivalo yentsimbi efakwe ngobushushu kwikhonkrithi eqinisiweyo.
