Uhlobo lwentsimbi

 

Intsimbi enyibilikisiweyo eveliswa esithandweni iphoswa kwiibhilethi, kwaye ii-ingots okanye iibhilethi zicinezelwa kwintsimbi (iimveliso zentsimbi). Kukho iintlobo ezininzi zentsimbi, ezinokwahlulwahlulwa zibe ziindidi ezine: iimolds, iiplates, iityhubhu kunye neengcingo.

 

Intsimbi yeCandelo

Kukho iintlobo ngeentlobo zentsimbi eqingqiweyo, oluluhlobo lwentsimbi ende eqinileyo enobume obuthile kunye nobukhulu obuthile. Ngokweemilo ezahlukeneyo zentsimbi eqingqiweyo, yahlulwe yaba ziintlobo ezimbini: imigca elula neyinkimbinkimbi. Eyokuqala ibandakanya iibha ezingqukuva, iibha ezisikwere, iibha ezisicaba, iibha ezisicaba kunye neebha ze-engile; Eyokugqibela ibandakanya iirail, ii-I-beams, iintsimbi zetshaneli, iintsimbi zefreyimu yefestile kunye neentsimbi ezinemilo ekhethekileyo. Intsimbi encinci engqukuva enobubanzi obuyi-6.5-9.0mm ibizwa ngokuba yi-wire.

 

Iipleyiti zentsimbi

Yintsimbi ethe tyaba enomlinganiselo omkhulu wobubanzi nobukhulu kunye nommandla womphezulu. Ngokweentlobo ezahlukeneyo zobukhulu, yahlulwe yaba ziintlobo ezintathu: ipleyiti ebhityileyo (ubukhulu < 4mm), ipleyiti ephakathi (ubukhulu 4-25mm) kunye nepleyiti etyebileyo (ubukhulu > 25mm). Imicu yentsimbi ifakiwe kudidi lwepleyiti yentsimbi.

 

Iipayipi zentsimbi

Yintambo ende yentsimbi enecandelo elingenanto. Ngokweemilo zayo ezahlukeneyo ezinqamlezileyo, inokwahlulwa ibe yimibhobho engqukuva, imibhobho eyisikwere, imibhobho enamacala asibhozo kunye nemibhobho eyahlukeneyo yentsimbi enqamlezileyo enemilo ekhethekileyo. Ngokwetekhnoloji eyahlukileyo yokucubungula, inokwahlulwa ibe ziindidi ezimbini: umbhobho wentsimbi ongenamthungo kunye nombhobho wentsimbi odibeneyo.

 

Iingcingo zentsimbi

Ucingo lwentsimbi ngomnye umkhiqizo wentambo osebenza ngokubandayo. Ngokweemilo ezahlukeneyo, lwahlulwe lwaba lucingo lwentsimbi olungqukuva, ucingo lwentsimbi olusicaba kunye nocingo lwentsimbi olunxantathu, njl. Ukongeza ekusetyenzisweni ngokuthe ngqo, ucingo lwentsimbi lukwasetyenziswa ekuveliseni iintambo zentsimbi, imigca yentsimbi kunye nezinye iimveliso.

 

Intsimbi ye-Angle

I-Angle steel, eyaziwa ngokuba yi-angle iron, ngumcu omde wentsimbi othe nkqo omnye komnye kumacala omabini. Kukho i-angle steel elinganayo kunye ne-angle steel engafaniyo. Amacala amabini e-engile elinganayo alingana ngobubanzi. Iinkcukacha zayo zichazwa ngeemilimitha zobubanzi becala.× ububanzi becala× ubukhulu bomphetho. Umzekelo, "∠30×30×3", oko kuthetha ukuba ububanzi becala yi-30 mm kwaye ubukhulu becala yi-3 mm. Ingabonakaliswa ngenombolo yomzekelo, elinani leesentimitha zobubanzi becala, njenge∠3#. Le modeli ayimeli ubungakanani bobukhulu obuhlukeneyo becala kwimodeli efanayo, ngoko ke ububanzi becala kunye nobukhulu becala lentsimbi ye-engile zizaliswe kwisivumelwano nakwamanye amaxwebhu, ukuze kuthintelwe ukusebenzisa le modeli yodwa. Iinkcukacha zentsimbi ye-engile elinganayo ejikeleziweyo eshushu yi-2#-20#.　　

Intsimbi ye-engile inokwenziwa ngezinto ezahlukeneyo ezixineneyo ngokweemfuno ezahlukeneyo zesakhiwo, kwaye ingasetyenziswa njengesiqhagamsheli phakathi kwezinto. Isetyenziswa kakhulu kwizakhiwo ezahlukeneyo zezakhiwo kunye nezakhiwo zobunjineli, ezifana neebhari zendlu, iibhulorho, iinqaba zothutho, oomatshini bokuphakamisa nezokuthutha, iinqanawa, izitofu zoshishino, iinqaba zokusabela, iirakhi zeekhonteyina kunye neeshelufu zeendawo zokugcina impahla.

 

Intsimbi ejikelezileyo

 

Intsimbi engqukuva ibhekisa kumcu oqinileyo wentsimbi onecandelo elijikelezayo. Iinkcukacha zayo zichazwe ngeemilimitha zobubanzi, umz. "50" ithetha ibha engqukuva enobubanzi obuyi-50 mm. Kukho iintlobo ezintathu zeebha ezingqukuva: ezijijekileyo ezishushu, ezibunjiweyo nezitsalwa ngokubandayo. Iibha ezingqukuva ezijijekileyo ezishushu ziyafumaneka ngobukhulu obuphakathi kwe-5.5 ukuya kwi-250 mm. Phakathi kwazo: Intsimbi encinci engqukuva eyi-5.5-25 mm inikwa kakhulu kwiibhanti zeebhanti ezithe tye, ezihlala zisetyenziswa njengeebhanti zentsimbi, iibholiti kunye neendawo ezahlukeneyo zoomatshini; Iibhanti ezingqukuva ezinkulu kune-25 mm zisetyenziselwa ukwenza iindawo zoomatshini okanye iibhanti zetyhubhu yentsimbi engenamthungo.

 

I-Rebar

Ibha yentsimbi yekhonkrithi eqinisiweyo ibhekisa kwibha ethe tye okanye intsimbi yentsimbi esetyenziselwa ukuqinisa ikhonkrithi eqinisiweyo, kwaye ubume bayo bahlulwe baba ziintlobo ezimbini: ibha yentsimbi ejikelezileyo ekhanyayo kunye nebha yentsimbi egobileyo, kwaye imeko yokuhanjiswa kwayo yibha ethe tye kunye nediski ejikelezileyo. Ibha yentsimbi ejikelezileyo ekhanyayo ngokwenene yintsimbi encinci ejikelezileyo kunye nediski yentsimbi eqhelekileyo esezantsi yekhabhoni. Iibha zentsimbi egobileyo ziibha zentsimbi ezigobileyo ezinomphezulu, zihlala zineimbambo ezinde ezimbini kunye neembambo ezinqamlezileyo ezibekwe ngokulinganayo kubude. Kukho iintlobo ezintathu zeembambo ezinqamlezileyo: i-spiral, i-herringbone kunye ne-crescent. Ibonakaliswa ngeemilimitha zobubanzi obuqhelekileyo. Ububanzi obuqhelekileyo bokuqinisa obugobileyo bulingana nobubanzi obuqhelekileyo bokuqinisa okujikelezileyo okulinganayo. Ububanzi obuqhelekileyo bebha yentsimbi yi-8-50 mm, kwaye ububanzi obucetyiswayo yi-8, 12, 16, 20, 25, 32, 40 mm.　　

Iibhari zokuqinisa ziphantsi koxinzelelo lokuxinana kwikhonkrithi. Ngenxa yesenzo seembambo, ibhari yentsimbi eguqukileyo inomthamo omkhulu wokubopha kwikhonkrithi, ngoko ke inokumelana ngcono nesenzo samandla angaphandle. Iibhari zentsimbi zisetyenziswa kakhulu kwizakhiwo ezahlukeneyo zezakhiwo, ngakumbi izakhiwo ezinkulu, ezinzima, ezikhaphukhaphu, ezineendonga ezincinci kunye nezakhiwo eziphakamileyo.

 

Intsimbi yetshaneli

Intsimbi yetshaneli ngumcu omde wentsimbi one-cross-section eneemiqolo. Indlela yayo yokubonisa iinkcukacha, efana ne-120*53*5, ibonisa intsimbi yetshaneli enobude besinqe obuyi-120 mm kunye nobubanzi bomlenze obuyi-53 mm, kunye nentsimbi yetshaneli enobukhulu besinqe obuyi-5 mm, okanye intsimbi yetshaneli eyi-12#. Ukuba kukho ububanzi bemilenze eyahlukeneyo kunye nobukhulu besinqe, kufuneka wongeze u-A, B, kunye no-C kwicala lasekunene lemodeli ukuze ubahlule, njenge-25A#, 25B#, 25C#, njl. Intsimbi yetshaneli yahlulwe yaba yintsimbi yetshaneli eqhelekileyo kunye nentsimbi yetshaneli ekhanyayo. Iinkcukacha zentsimbi yetshaneli eqhelekileyo eqengqelekayo eshushu yi-5-40#. Iinkcukacha zentsimbi yetshaneli eguquguqukayo eqengqelekayo eshushu enikezelwa ngesivumelwano phakathi kwamaqela okubonelela kunye nemfuno yi-6.5-30#.

Intsimbi yesiteshi isetyenziswa kakhulu kwizakhiwo zokwakha, ukwenziwa kwezithuthi kunye nezinye izakhiwo zoshishino, kwaye intsimbi yesiteshi idla ngokusetyenziswa kunye nee-I-beams.
