Uhlobo lwensimbi

 

Insimbi encibilikisiwe ekhiqizwa esithandweni iphonswa kuma-billet, bese ama-ingot noma ama-billet acindezelwa abe yinsimbi (imikhiqizo yensimbi). Kunezinhlobo eziningi zensimbi, ezingahlukaniswa ngezigaba ezine: isikhunta, amapuleti, amashubhu kanye nezintambo.

 

Insimbi yesigaba

Kunezinhlobo eziningi zensimbi yesigaba, okuwuhlobo lwensimbi ende eqinile enomumo nosayizi othize wesigaba. Ngokwezinhlobo ezahlukene zesigaba, ihlukaniswe ngezinhlobo ezimbili: izigaba ezilula neziyinkimbinkimbi. Eyokuqala ihlanganisa imigoqo eyindilinga, imigoqo eyisikwele, imigoqo eyisicaba, imigoqo enezinhlangothi eziyisithupha kanye nemigoqo ye-engeli; Eyokugcina ihlanganisa ama-rails, ama-I-beams, izinsimbi zesiteshi, izinsimbi zohlaka lwefasitela kanye nezinsimbi ezimise okwehlukile. Insimbi encane eyindilinga enobubanzi obungu-6.5-9.0mm ibizwa ngokuthi ucingo.

 

Amapuleti ensimbi

Yinsimbi eyisicaba enesilinganiso esikhulu sobubanzi nobukhulu kanye nendawo yobuso. Ngokusho kobukhulu obuhlukene, ihlukaniswe ngezinhlobo ezintathu: ipuleti elincane (ukujiya < 4mm), ipuleti eliphakathi (ukujiya 4-25mm) kanye nepuleti elijiyile (ukujiya > 25mm). Imichilo yensimbi ifakiwe esigabeni sepuleti lensimbi.

 

Amapayipi ensimbi

Iwumucu omude wensimbi onengxenye engenalutho. Ngokwezimo zayo ezahlukene zezingxenye eziphambeneyo, ingahlukaniswa ngamapayipi ayindilinga, amapayipi asikwele, amapayipi ayisithupha kanye namapayipi ensimbi ahlukahlukene anesimo esikhethekile. Ngokwezobuchwepheshe obuhlukene bokucubungula, ingahlukaniswa ngezigaba ezimbili: ipayipi lensimbi elingenamthungo kanye nepayipi lensimbi elihlanganisiwe.

 

Izintambo zensimbi

Ucingo lwensimbi ngomunye umkhiqizo wentambo osebenza ngokubandayo. Ngokwezimo ezahlukene, luhlukaniswe ngocingo lwensimbi oluyindilinga, ucingo lwensimbi oluyisicaba kanye nocingo lwensimbi oluyinxantathu, njll. Ngaphezu kokusetshenziswa ngqo, ucingo lwensimbi lusetshenziswa nasekukhiqizweni kwezintambo zensimbi, imigqa yezinhlamvu zensimbi neminye imikhiqizo.

 

Insimbi ye-engela

Insimbi engela, eyaziwa kakhulu ngokuthi insimbi engela, iwumucu omude wensimbi oqondene nhlangothi zombili. Kunensimbi engela elinganayo kanye nensimbi engela engafani. Izinhlangothi ezimbili ze-engela elinganayo zilingana ngobubanzi. Imininingwane yayo ivezwa ngamamilimitha obubanzi bezinhlangothi.× ububanzi becala× ukujiya komphetho. Isibonelo, "∠30×30×3", okusho ukuthi ububanzi becala bungu-30 mm kanti ubukhulu becala bungu-3 mm. Kungabuye kuvezwe ngenombolo yemodeli, okuyinani lamasentimitha obubanzi becala, njengokuthi∠3#. Imodeli ayimeleli ubukhulu bobukhulu obuhlukene bezinhlangothi kumodeli efanayo, ngakho ububanzi bezinhlangothi kanye nobukhulu bezinhlangothi zensimbi ye-engeli kugcwaliswe enkontilekeni nakwamanye amadokhumenti, ukuze kugwenywe ukusebenzisa imodeli yodwa. Imininingwane yensimbi ye-engeli elinganayo egoqekile eshisayo ingu-2#-20#.　　

Insimbi egobile ingakhiwa izingxenye ezahlukene ezicindezelwe ngokwezidingo ezahlukene zesakhiwo, futhi ingasetshenziswa njengesixhumi phakathi kwezingxenye. Isetshenziswa kabanzi ezakhiweni ezahlukene zezakhiwo kanye nezakhiwo zobunjiniyela, njengemishayo yendlu, amabhuloho, imibhoshongo yokudlulisa, imishini yokuphakamisa nezokuthutha, imikhumbi, izitofu zezimboni, imibhoshongo yokusabela, ama-container racks kanye namashalofu ezimpahla zokugcina impahla.

 

Insimbi eyindilinga

 

Insimbi eyindilinga ibhekisela kumugqa wensimbi oqinile onesigaba esiyindilinga. Imininingwane yayo ivezwa ngamamilimitha ububanzi, isib. "50" isho ibha eyindilinga enobubanzi obungu-50 mm. Kunezinhlobo ezintathu zemigoqo eyindilinga: egoqwe ngokushisa, eyenziwe ngobumba kanye nedonswa ngokubandayo. Imigoqo eyindilinga egoqwe ngokushisa itholakala ngobukhulu obusukela ku-5.5 kuya ku-250 mm. Phakathi kwazo: insimbi encane eyindilinga engu-5.5-25 mm ihlinzekwa kakhulu ngezinqwaba zemigoqo eqondile, evame ukusetshenziswa njengemigoqo yensimbi, amabhawodi kanye nezingxenye ezahlukahlukene zemishini; Imigoqo eyindilinga emikhulu kuno-25 mm isetshenziswa kakhulu ukwenza izingxenye zemishini noma izikhala zepayipi lensimbi ezingenamthungo.

 

I-Rebar

Ibha yensimbi yekhonkrithi eqinisiwe ibhekisela kubha eqondile noma insimbi yomugqa wensimbi esetshenziselwa ukuqinisa ikhonkrithi eqinisiwe, futhi ukuma kwayo kuhlukaniswe izinhlobo ezimbili: ibha yensimbi eyindilinga elula kanye nebha yensimbi egobile, kanti isimo sokulethwa siyibha eqondile kanye nediski eyindilinga. Ibha yensimbi eyindilinga elula empeleni iyindilinga encane yensimbi eyindilinga kanye nediski yensimbi ejwayelekile ephansi yekhabhoni. Ibha yensimbi egobile iyibha yensimbi enezinti enobuso, ngokuvamile enezinti ezimbili ezinde kanye nezinti ezigobile ezibekwe ngokulinganayo ubude. Kunezinhlobo ezintathu zezinti ezigobile: i-spiral, i-herringbone kanye ne-crescent. Ivezwa ngamamilimitha obubanzi obujwayelekile. Ububanzi obujwayelekile bokuqinisa okugobile bulingana nobubanzi obujwayelekile bokuqinisa okujikelezayo okulinganayo. Ububanzi obujwayelekile bebha yensimbi bungu-8-50 mm, kanti ububanzi obunconywayo bungu-8, 12, 16, 20, 25, 32, 40 mm.　　

Imigoqo yokuqinisa ivame ukucindezelwa kakhulu kukhonkolo. Ngenxa yesenzo sezimbambo, umgoqo wensimbi okhubazekile unamandla amakhulu okubopha kukhonkolo, ngakho-ke ungamelana kangcono nesenzo samandla angaphandle. Imigoqo yensimbi isetshenziswa kabanzi ezakhiweni ezahlukene zezakhiwo, ikakhulukazi izakhiwo ezinkulu, ezisindayo, ezilula, ezinezindonga ezincane nezinde.

 

Insimbi yesiteshi

Insimbi yesiteshi iwumucu omude wensimbi one-cross-section enemiphetho. Indlela yayo yokumelela imininingwane, njenge-120*53*5, ikhombisa insimbi yesiteshi enokuphakama kwesinqe okungu-120 mm kanye nobubanzi bomlenze obungu-53 mm, kanye nensimbi yesiteshi enobukhulu besinqe obungu-5 mm, noma insimbi yesiteshi engu-12#. Uma kunezinhlobo eziningana ezahlukene zobubanzi bemilenze kanye nobukhulu besinqe, udinga futhi ukwengeza u-A, B, kanye no-C ohlangothini lwesokudla lwemodeli ukuze uzihlukanise, njenge-25A#, 25B#, 25C#, njll. Insimbi yesiteshi ihlukaniswe ngensimbi yesiteshi evamile kanye nensimbi yesiteshi esilula. Imininingwane yensimbi yesiteshi evamile egoqwe ngokushisa ingu-5-40#. Imininingwane yensimbi yesiteshi eguquguqukayo egoqwe ngokushisa enikezwa ngesivumelwano phakathi kwamaqembu okuphakelwa kanye nesidingo ingu-6.5-30#.

Insimbi yesiteshi isetshenziswa kakhulu ezakhiweni zokwakha, ekukhiqizweni kwezimoto nakwezinye izakhiwo zezimboni, kanti insimbi yesiteshi ivame ukusetshenziswa kanye ne-I-beams.
