I-Rebar Hrb355 Hrb400 Hrb500 8mm 10mm 12mm 14mm 16mm Ibha enomvalo

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% ye-perimeter ye-nominal ye-bar yensimbi;
Xa i-diameter ekhethiweyo yentsimbi yentsimbi 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 ingaphezu 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;
