IiMveliso eziNgqongileyo zenziwe kwiFactory yaseTshayina iRebar yeNtsimbi ekumgangatho oPhezulu oQinisekisiweyo weNsimbi yeCarbon eNcinciweyo/iRebar yokwakha

Singabavelisi abanamava.Ukuphumelela uninzi kwizatifikethi ezibalulekileyo zentengiso yazo yeeMveliso eziNgqongileyo ezenziwe kwiFactory yaseTshayina iRebar yentsimbi yoMgangatho oPhezulu oQinisekisiweyo weCarbon Steel Bar/iRebar yoKwakha, Wamkelekile ukulungiselela umtshato wexesha elide nathi.Elona xabiso lisebenzayo lokuthengisa ngoNaphakade Umgangatho eTshayina.
Singabavelisi abanamava.Ukuphumelela uninzi kwiziqinisekiso ezibalulekileyo zemarike yayoI-China Rebar kunye ne-HRB500 ye-Steel Rebar, Umzi-mveliso wethu ugxininisa kumgaqo othi "uMgangatho wokuQala, uPhuhliso oluZinzileyo", kwaye uthatha "uShishino olunyanisekileyo, izibonelelo ezihlangeneyo" njengenjongo yethu yokuphuhlisa.Onke amalungu enkosi ngokunyanisekileyo ngayo yonke inkxaso yabathengi abadala nabatsha.Siza kuqhubeka sisebenza nzima kwaye sikunika izisombululo ezikumgangatho ophezulu kunye nenkonzo.Enkosi.

ukuhlelwa

Ibha yensimbi eshushu eqengqelekayo ihlukaniswe ngamabakala amathathu: i-HRB335 (ibakala elidala yi-20MnSi), ibakala lesithathu i-HRB400 (ibakala elidala liyi-20MnSiV, i-20MnSiNb, i-20Mnti), kunye ne-HRB500 yesine.
Zimbini iindlela zokuhlela eziqhele ukusetyenziswa zokuqinisa imivalo:enye kukuhlelwa ngokwemilo yejometri, kwaye enye kukwahlula okanye ukuhlela ngokwemilo enqamlezileyo yeebha ezinqamlezileyo kunye nezithuba zemivalo.Uhlobo lwe-II. Olu lwahlulo lubonisa ngokukodwa ukusebenza kwe-clamping yokuqinisa.

Okwesibini kuhambelana nokuhlelwa kwentsebenzo (ibakala), njengomgangatho wokuphunyezwa kwangoku kwilizwe lam, i-rebar yi (GB1499.2-2007) ucingo ngu-1499.1-2008), kwaye i-rebar yahlulwe yaba yi-3 ibakala lamandla (inqaku lesivuno/amandla okuqina).iBanga;kwiMigangatho yoShishino lwaseJapan (JI SG3112), imivalo yensimbi ihlulwe kwiindidi ezi-5 ngokweempawu zazo ezibanzi;kuMgangatho waseBrithani (BS4461), amanqanaba amaninzi ovavanyo lwentsimbi yentsimbi nawo achaziwe.Ukongeza, imivalo yentsimbi inokuthi ihlelwe ngokusetyenziswa, njengemivalo yentsimbi eqhelekileyo yekhonkrithi eqinisiweyo kunye neentsimbi zentsimbi ezifakwe ngobushushu kwikhonkrithi eqinisiweyo.

inkalo

1) Uluhlu lwedayamitha ekhethiweyo kunye nedayamitha ecetyiswayo
Ubungakanani obuqhelekileyo beentsimbi zetsimbi ukusuka kwi-6 ukuya kwi-50mm, kunye nomgangatho ophakanyisiweyo we-diameters yentsimbi yentsimbi yi-6, 8, 10, 12, 14, 16, 20, 25, 32, 40, kunye ne-50mm.
2) Ukuphambuka okuvumelekileyo kwimilo yomhlaba kunye nobukhulu bentsimbi ye-ribbed bar
Imigaqo yokuyila yeentsimbi zetsimbi kufuneka ihlangabezane nezi mfuno zilandelayo:
I-angle β phakathi kwembambo enqamlezayo kunye nentsimbi yentsimbi akufanele ibe ngaphantsi kwama-45 degrees.Xa i-angle edibeneyo ingekho ngaphezu kwama-degrees angama-70, isalathiso semivalo enqamlezileyo kumacala omabini entsimbi yentsimbi kufuneka ichasene;
Isithuba se-l semivalo enqamlezileyo akufuneki sibe sikhulu kuno-0.7 ngokuphinda-phindwe kabini kwedayamitha yegama leebar;
I-angle α phakathi kwecala leembambo ezinqamlezileyo kunye nobuso bentsimbi yentsimbi ayiyi kuba ngaphantsi kwama-45 degrees;
Isixa sezithuba (kubandakanywa nobubanzi beembambo ze-longitudinal) eziphelweni zeembambo ezinqamlezileyo kumacala omabini ajongene nentsimbi yentsimbi ayiyi kuba ngaphezu kwe-20% yomjikelezo oqhelekileyo wentsimbi yentsimbi;
Xa i-diameter ekhethiweyo ye-bar yensimbi ayikho ngaphezu kwe-12mm, indawo yembambo enxulumene nayo ayifanele ibe ngaphantsi kwe-0.055;xa i-diameter engu-14mm kunye ne-16mm, indawo yembambo ehlobene akufanele ibe ngaphantsi kwe-0.060;xa i-diameter ye-nominal ingaphezulu kwe-16mm, indawo yembambo ehlobene akufanele ibe ngaphantsi kwe-0.065.Jonga kwiSihlomelo C xa kubalwa indawo yembambo ezalanayo.
Imivalo yetsimbi ye-Ribbed ngokubanzi inemivalo ye-longitudinal, kwaye kukho nalawo angenayo imivalo ye-longitudinal;

3) Ubude kunye nokuphambuka okuvumelekileyo
Nye.ubude
Imivalo yensimbi idla ngokuhanjiswa ngobude obusisigxina, kwaye ubude obuthile bokuhanjiswa kufuneka buboniswe kwinkontileka;
Iintsimbi zensimbi zinokuhanjiswa kwimiqulu, umqulu ngamnye kufuneka ube yintsimbi enye, kwaye i-5% yenani lemiqulu kwibhetshi nganye (ngaphantsi kwee-rolls ezimbini ziyimiqulu emibini) iqulethe iintsimbi ezimbini zetsimbi.Ubunzima bedisk kunye nedayamitha yedisk bumiselwa ngothethwano phakathi komthengisi kunye nomthengi.
b.Ukunyamezela ubude
Xa ubude obumiselweyo buhanjiswa, ukuphambuka okuvumelekileyo kobude bentsimbi yentsimbi akukho ngaphezu kwe-± 25mm;
Xa ubude obuncinane bufunekayo, ukuphambuka ku-+50mm;
Xa ubude obude bufunekayo, ukuphambuka ku-50mm.
c.Igophe kunye neziphelo
Ukuphela kwentsimbi yentsimbi kufuneka kunqunywe ngokuthe tye, kwaye i-deformation yendawo ayiyi kuchaphazela ukusetyenziswa
