Isishwankathelo sesicelo:Imivalo yentsimbi eqengqelekisiweyo eshushu isetyenziswa kakhulu kuloliwe ohamba ngesantya esiphezulu, kwiziko lamandla enyukliya, iindawo zeOlimpiki, iProjekthi yoLawulo lwaManzi eMiwonyo emithathu.
kunye nezinye iiprojekthi eziphambili zesizwe ngokunjalo nezinye izakhiwo ezibalulekileyo.Imivalo ejikelezayo isetyenziswa ngokubanzi kwiinqanawa, izithuthi, iinqwelomoya, oololiwe, iibhulorho,iinqanawa zoxinzelelo, izixhobo zesixhobo somatshini.

Ukuhlelwa kweMveliso

Kukho iindlela ezimbini ezisetyenziswa ngokuqhelekileyo zokuhlelwa kwe-rebar: enye kukuhlelwa ngokwemilo yejometri, kunye nokuhlelwa okanye ukuchwetheza ngokwemilo enqamlezileyo yembambo enqamlezileyo kunye nezithuba zeembambo.Uhlobo II.Olu lwahlulo lubonisa ubukhulu becala ukusebenza okubambekayo kwe-rebar.Eyesibini isekelwe kuhlelo lwentsebenzo (ibakala), njengomgangatho wokuphunyezwa kwelizwe lam ngoku, i-rebar yi (GB1499.2-2007) ucingo yi-1499.1-2008), ngokwenqanaba lamandla (inqanaba lesivuno / amandla okuqina) I-rebar i yahlulwe yangamabanga ama-3;kwiMigangatho yoShishino lwaseJapan (JI SG3112), i-rebar yahlulwe yaba ziindidi ezi-5 ngokwentsebenzo ebanzi;kuMgangatho waseBritani (BS4461), amabakala amaninzi ovavanyo lwentsebenzo yerebar nawo achaziwe.Ukongeza, ii-rebars ziyakwazi ukuhlelwa ngokokusetyenziswa kwazo, njengemivalo yentsimbi eqhelekileyo yekhonkrithi eyomeleziweyo kunye nemivalo yentsimbi egxininiswe ngobushushu kwikhonkrithi eyomeleziweyo.

Imilinganiselo yeMveliso

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 yoyilo lweembambo ezinqamlezileyo zeentsimbi zentsimbi ziya kuhlangabezana nezi mfuno zilandelayo:

I-angle β phakathi kweembambo ezinqamlezayo kunye ne-axis yentsimbi yentsimbi akufanele ibe ngaphantsi kwama-45 degrees.Xa i-angle efakiweyo ingekho ngaphezu kwama-70 degrees, isalathiso seembambo ezinqamlezileyo kumacala achasene nentsimbi yentsimbi kufuneka zichasane;

Isithuba esincinci se-l yeembambo ezinqamlezileyo asiyi kuba sikhulu kune-0.7 amaxesha obubanzi obuqhelekileyo bentsimbi yentsimbi;

I-angle α phakathi kwecala leembambo ezinqamlezileyo kunye nobuso bentsimbi yentsimbi ayiyi kuba ngaphantsi kwama-45 degrees;

Isixa sezithuba (kubandakanywa nobubanzi beembambo ze-longitudinal) phakathi kweziphelo zeembambo ezinqamlezileyo kumacala amabini ajongene nentsimbi yentsimbi ayiyi kuba ngaphezu kwe-20% yomjikelezo oqhelekileyo wentsimbi yentsimbi;

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 ngokuqhelekileyo ineembambo ze-longitudinal, kodwa kwakhona ngaphandle kweembambo ze-longitudinal;

3) Ubude kunye nokuphambuka okuvumelekileyo

A. Ubude:
Imivalo yensimbi idla ngokuhanjiswa ngobude obusisigxina, kwaye ubude obuthile bokuhanjiswa kufuneka buboniswe kwinkontileka;
Imivalo yokuqinisa inokuhanjiswa kwiikhoyili, kwaye i-reel nganye kufuneka ibe yi-rebar enye, ivumela i-5% yenani lee-reels kwibhetshi nganye (ii-reels ezimbini ukuba zingaphantsi kwe-2) ezibandakanya ii-rebar ezimbini.Ubunzima bedisk kunye nedayamitha yedisk bumiselwa ngothethwano phakathi komthengisi kunye nomthengi.

B. ukunyamezela ubude:
Ukuphambuka okuvumelekileyo kobude bentsimbi yentsimbi xa ihanjiswa kubude obusisigxina ayiyi kuba ngaphezu kwe-± 25mm;
Xa ubude obuncinane bufunekayo, ukuphambuka kwayo +50mm;
Xa ubude obude bufunekayo, ukuphambuka ku-50mm.

C. igophe kunye neziphelo:
Ukuphela kwentsimbi yentsimbi kufuneka kuchetywe ngokuthe tye, kwaye i-deformation yendawo akufanele ichaphazele ukusetyenziswa.
