Umbhobho wentsimbi engenamthungo oshushu oqengqekileyoEN10210 S355J2Hngumbhobho wentsimbi oqinileyo nowomeleleyo, osetyenziswa kakhulu kwiinkalo ezahlukeneyo zoshishino kunye neeprojekthi zobunjineli. Nazi iindlela eziphambili zokusetyenziswa kwayo kunye nemiba ekufuneka iqwalaselwe xa uthenga:
Ushishino kunye nokusetyenziswa:
Uyilo lwezakhiwo kunye nobunjineli bezakhiwo:
Isetyenziselwa izakhelo zesakhiwo sentsimbi, iibhulorho, iinqaba, njl.njl. zezakhiwo.
Yenza iikholamu ezithwala imithwalo, imiqadi, ii-trusses kunye nezinye iindawo zesakhiwo.
Ukuveliswa koomatshini:
Isetyenziselwa ukwenza izibiyeli, izakhelo kunye neenxalenye zezixhobo zoomatshini.
Kubandakanya izixhobo ezithwala imithwalo ezifana neekhreyini kunye neenkqubo zokuhambisa.
Ishishini lamandla:
Isetyenziselwa iinqaba zamandla omoya, imibhobho yeoyile negesi kunye nezinye izixhobo ezinxulumene namandla.
Ubunjineli beenqanawa kunye nolwandle:
Isetyenziswa kwiindawo ezakhiweyo zamaqonga neenqanawa ezikude nolwandle.
Amanyathelo okhuseleko xa uthenga:
Izixhobo kunye nomgangatho:
I-S355 ithetha ukuba amandla okukhupha yi-355 MPa;
I-J2 ithetha ukuba ukuqina kwempembelelo kwi--20°C kuyahlangabezana neemfuno;
U-H uthetha intsimbi engenanto.
Ubukhulu kunye nokunyamezelana:
Jonga ukuba iinkcukacha zobubanzi bangaphandle, ubukhulu bodonga kunye nobude ziyahlangabezana na neemfuno zoyilo lweprojekthi.
Qinisekisa ukuba ukunyamezelana okulinganayo kungaphakathiEN 10210umgangatho.
Amaxwebhu esiqinisekiso somgangatho (MTC, 3.1/3.2):
Umenzi kufuneka anikezele ngamaxwebhu okuqinisekisa umgangatho ngokuhambelana ne-EN 10204, kuquka ukwakheka kweekhemikhali, iimpawu zoomatshini kunye neengxelo zovavanyo ezingonakalisiyo.
Umgangatho womphezulu kunye nokufunyanwa kweziphene:
Umphezulu mawungabi naziphene ezicacileyo ezifana nokuqhekeka, umhlwa, ukuxinana, njl.
Jonga ukuba iphumelele na uvavanyo olungonakalisiyo (njengovavanyo lwe-ultrasound), ingakumbi kwiindawo ezibalulekileyo ezithwala umthwalo.
Ukumelana nokugqwala kunye nonyango emva konyango:
Ukuba isetyenziswa kwindawo enokugqwala, kufuneka kuqinisekiswe ukuba kuyimfuneko na ukugquma okanye ukugalela i-galvanizing.
Kukwanokwenzeka ukuqwalasela ukuba unyango lobushushu (njengokulungisa okanye ukupholisa) luyafuneka na ukuphucula ukusebenza.
Iimfaneleko zomthengisi:
Khetha ababoneleli abanegama elihle kunye nomgangatho ozinzileyo ukuqinisekisa ukuhambelana kwemveliso.
Kwiiodolo ezinkulu, amandla okuvelisa umzi-mveliso angahlolwa kwindawo leyo.
Uthutho kunye nokuhanjiswa:
Qinisekisa ukuba indlela yokuthutha ingakuphepha na ukuguquka okanye umonakalo womphezulu wombhobho.
Ingakumbi kwiipayipi ezinde, kuyimfuneko ukunikela ingqalelo ekhethekileyo kwiindlela zokupakisha nokulungisa.
Ixabiso kunye nexesha lokuhanjiswa:
Nika ingqalelo ekutshintsheni kwamaxabiso ezinto eziluhlaza kwimarike kwaye ubeke amaxabiso okuthenga afanelekileyo ngexesha elifanelekileyo.
Coca umjikelo wokuhanjiswa kwezinto ukuze uphephe ukulibaziseka ngenxa yenkqubela phambili yeprojekthi.
Njengoko ukuphela konyaka kusondela, iindleko zokuthumela zinyuka. Nceda uqinisekise umhla wokuhanjiswa kwaye ulawule iindleko.
