Uma kukhulunywa ngezingxenye zensimbi ezakhiwe,Iziteshi ze-UfuthiIziteshi ze-Cziyiziphrofayili ezimbili ezisetshenziswa kakhulu ekwakheni nasekukhiqizeni. Zombili izinhlobo zeziteshi zidlala indima ebalulekile ezinhlotsheni ezahlukene zezicelo, kodwa zinezakhiwo ezahlukene ezenza zifanelekele ukusetshenziswa okuhlukile. Ukuqonda umehluko phakathi kweziteshi ze-U kanye neziteshi ze-C kubalulekile konjiniyela, abakhi bezakhiwo, kanye nabakhi ukuze bakhethe izinto ezifanele amaphrojekthi abo.
Iziteshi ze-U, ezivame ukubizwa ngokuthi i-U-beams noma i-U-sections, zibonakala ngesigaba sazo esinobunjwa obungu-U. Lo mklamo unemilenze emibili eqondile exhunywe ngesisekelo esivundlile, esifana nohlamvu "U". Izinhlangothi ezivulekile zesiteshi se-U zingaxhunywa kalula kwezinye izinto, okwenza kube ukukhetha okuguquguqukayo kwezinhlelo zokusebenza ezahlukahlukene.
Ngakolunye uhlangothi, i-Isiteshi se-C(ebizwa nangokuthi i-C-beam noma i-C-section) ine-cross-section emise okwe-C. Njenge-U-channel, i-C-channel inemilenze emibili eqondile kanye nesisekelo esivundlile, kodwa udebe olusekugcineni kwemilenze lubonakala kakhulu, okwenza lube nesimo se-C esihlukile. Lo mklamo unikeza amandla engeziwe kanye nokuqina, okwenza i-C-channel ibe ukukhetha okuthandwayo kwezicelo zesakhiwo.
Omunye wemimehluko emikhulu phakathi kweziteshi ze-U kanye neziteshi ze-C amandla azo kanye nomthamo wazo wokuthwala umthwalo. Ngenxa yokwakheka kwazo, iziteshi ze-C ngokuvamile zibhekwa njengezinamandla kuneziteshi ze-U. Udebe olungeziwe ekugcineni kwemilenze yesiteshi se-C lukhulisa ukumelana kwalo nokugoba nokusonta, okwenza kube kuhle kakhulu ekusetshenzisweni okudinga umthamo omkhulu wokuthwala umthwalo.
Nakuba isaqinile, isiteshi se-U singase singanikeli izinga elifanayo lokusekela njengesiteshi se-C. Kodwa-ke, ukwakheka kwaso okuvulekile kuvumela ukuguquguquka okukhulu kwezinye izinhlelo zokusebenza, njengalapho sidinga ukushiselwa noma ukuboshelwa kwezinye izingxenye. Ukukhetha phakathi kwalokhu okubili kuvame ukuncika ezidingweni ezithile zephrojekthi, kufaka phakathi imithwalo okumele isekele kanye nohlobo lokuxhumeka oludingekayo.
Iziteshi ze-U kanyeIziteshi ze-Czisetshenziswa kabanzi ekwakheni, ekukhiqizeni, kanye nasezinhlotsheni ezahlukene zezicelo zezimboni. Amashaneli e-U avame ukusetshenziswa ezinhlotsheni ezidinga ikhambi elilula neliguquguqukayo. Ukusetshenziswa okuvamile kufaka phakathi uhlaka, ukubopha, kanye nezisekelo zokubeka ama-rack noma imishini. Umklamo wazo ovulekile uhlangana kalula nezinye izinto, okwenza kube ukukhetha okuthandwayo kokwenziwa ngokwezifiso.
Amashaneli e-C avame ukusetshenziswa ezindleleni zokwakha ezifana nohlaka lokwakha, amabhuloho kanye nemishini esindayo ngenxa yamandla awo angavamile. Ayakwazi ukumelana nemithwalo emikhulu, okwenza abe afanele ukusetshenziswa ezindaweni lapho ukuqina nokuqina kubalulekile khona. Ngaphezu kwalokho,Iziteshi ze-Czivame ukusetshenziselwa ukwakha izinsimbi zokubiyela, amabhuleki nezinye izakhi zesakhiwo ezidinga uhlaka oluqinile.
Ngamafuphi, yize zombili iziteshi ze-U kanye neziteshi ze-C zidlala indima ebalulekile ekwakheni nasekukhiqizweni, zinemehluko ehlukene futhi zifanelekela izinhlelo zokusebenza ezahlukene. Iziteshi ze-U zilungele izakhiwo ezilula kanye namaphrojekthi enziwe ngokwezifiso ngenxa yokuguquguquka kwazo kanye nokulula kokuxhumana. Ngokuphambene nalokho, iziteshi ze-C zikhethwa kakhulu ezinhlelweni zokusebenza ezisindayo ngenxa yamandla azo aphezulu kanye nomthamo wokuthwala umthwalo. Ukuqonda lo mehluko kubalulekile ekukhetheni uhlobo olufanele lwesiteshi oluhambisana nezidingo zakho ezithile, ukuqinisekisa ukuthi iphrojekthi yakho iyaphumelela futhi iphephile.
→Ukuze uthole yonke imikhiqizo, izinsizakalo kanye nolwazi olusesikhathini, sicelaXhumana nathi.
