C iziteshi, eyaziwa nangokuthi ama-C Purlins noma izigaba C, izakhi zesakhiwo ezisetshenziswa kabanzi kwimisebenzi yokwakha. Lawa maphrofayli ensimbi aqinile futhi aguquguqukayo anezicelo ezahlukahlukene futhi ajwayele ukuqashwa njengohlelo lokusekelwa ezakhiweni noma njengamalungu e-Framing. Kulesi sihloko, sizoxoxa ngomsebenzi nezinhlobo ezahlukene zeziteshi ze-C.
Umsebenzi oyinhloko weziteshi ze-C ukuhlinzeka ukwesekwa kwesakhiwo. Ngokusabalalisa umthwalo ngokulinganayo, basiza ukuthuthukisa amandla nokuqina kwesakhiwo. Iziteshi ze-C zivame ukusetshenziswa njengemishayo, amakholomu, kanye nama-purlins. Njengoba imishayo, iyingxenye ebalulekile yohlaka, isekela isisindo sesakhiwo futhi iwudlulisele kusisekelo. Zingasetshenziswa futhi njengamakholamu, zidlala indima ebalulekile ekusekeleni ophahleni lwesakhiwo. Ngokwengeziwe, iziteshi ze-C zingasebenza njengama-purlins, zinikeze ukwesekwa kwesakhiwo edolweni yophahla futhi kudlulise isisindo ezindongeni ezithwala umthwalo.
C iziteshiWoza ngezinhlobo ezahlukahlukene, ngamunye okhonza injongo ethile. Ezinye izinhlobo ezijwayelekile zifaka phakathi okujwayelekile (noma okujwayelekile), okulahliwe kwe-flange, kanye neziteshi ze-strut C. Iziteshi ze-C ezijwayelekile, ezaziwa nangokuthi iziteshi zendabuko zendabuko, zinama-flanges womabili ubude. Zisetshenziswa kabanzi ekwakheni futhi zilungele kakhulu izinhlelo zokusebenza lapho kulindeleke khona imithwalo ekhanyayo. Ngakolunye uhlangothi, iziteshi ze-Flange C, ngakolunye uhlangothi, zine-flange eyodwa isikhathi eside kunenye, zakha umphumela oshisayo. Lo mklamo unyusa umthamo wokuthela umthwalo futhi uvame ukusetshenziswa kumaphrojekthi wezimboni. Iziteshi ze-Strut C zisetshenziswa ikakhulukazi ekufakweni kukagesi nokwenziwe ngomshini. Banezimbobo ezisebheke phezulu, zibavumela ukuba zifakwe kalula ezindongeni, phansi, noma ophahleni.
Ngokungeziwe ezinhlotsheni ezahlukahlukene, iziteshi ze-C nazo ziza ngosayizi nobukhulu obuhlukile ukuze bahlangabezane nezidingo ezithile zephrojekthi. Ubukhulu besiteshi se-C bunqunywa ukuphakama kwalo, ububanzi, nesisindo ngonyawo ngalunye. Lezi zilinganiso zichaza umthamo womthwalo namandla wokusekela wesiteshi. Lapho ukhetha isiteshi se-C, kubalulekile ukubheka izici ezinjenge-span, uhlobo lomthwalo, kanye nezimo zemvelo.
Izinzuzo zokusebenzisa iziteshi ze-C ziningi. Okokuqala, basinda, benza ukuba kube lula ukuphatha futhi bafake. Okwesibili, ukuguquguquka kwabo kuyabavumela ukuthi basetshenziswe ezinhlobonhlobo zezicelo, ezivela ezakhiweni zokuhlala kumaphrojekthi wezimboni. Okwesithathu,C iziteshiNikeza amandla aphezulu ezakhiwo ngenkathi edinga ukulungiswa okuncane. Baphinde bamelana nokugqwala, ukuqinisekisa ukuqina nokuphila isikhathi eside.
Ekuphetheni,C iziteshiIbamba iqhaza elibalulekile kumaphrojekthi wokwakha, ukuhlinzeka ukwesekwa kwesakhiwo kanye nokwenza ngcono amandla okuqina nokuqina kwesakhiwo. Beza ngezinhlobo ezahlukahlukene, osayizi, nobukhulu ukuhambisana nezicelo ezahlukahlukene nezidingo. Noma ngabe isetshenziswa njengemishayo, amakholomu, noma ama-purlins, iziteshi ze-C zinikeza ukuguquguquka, ukuqina, kanye nokufakwa kalula. Imvelo yabo engasindi, umthamo onamandla omthwalo aphezulu, kanye nokumelana nokugqwala kubenze kube yinhloso enhle yezidingo ezahlukahlukene zokwakha.
