Ukuba ukhangelaimijelo yentsimbi ye-CKwiprojekthi yolwakhiwo, mhlawumbi uqaphele ukuba zingaphi iinguqu zobukhulu ezikhoyo. Ukukhetha icandelo elifanelekileyo akupheleli nje kubunzulu — ububanzi beflegi, ubukhulu bewebhu, kunye nobunzima ngenyawo zonke ezi zinto zichaphazela umthamo womthwalo, iindleko zokwenziwa, kunye nobunzima bokuhambisa.Iqela leNsimbi yasebukhosini, sinikezela nge-AISC-standarditshaneli yesinyithi yesakhiwoukusuka kwi-C3 ukuya kwi-C15 ukuya kubathengi kulo lonke elaseMntla Melika, eLatin America, nakwezinye iindawo. Esi sikhokelo sidibanisa idatha yobukhulu, iinkcukacha zobunzima, kunye neempawu zesakhiwo ozidingayo ukuze ukhethe ngokuzithemba.

Ubungakanani beChannel C kwiMetric
Nangona inkqubo yokuchonga i-AISC isebenzisa ii-intshi neepawundi, uninzi lwabathengi bethu bamazwe ngamazwe - ngakumbi eYurophu, eMbindi Mpuma, nakuMzantsi-mpuma we-Asia - basebenza ngeemilimitha neekhilogram ngemitha nganye. Itshathi engasentla sele ibandakanya zombini iinkqubo ukuze ukwazi ukubhekisa ngokuthe ngqo ngaphandle kokwenza izibalo ngokwakho.
Ukuba usebenza kwiprojekthi echaza ubungakanani beetshaneli ze-metric (ezifana namacandelo e-UPN okanye e-UPE), ezo ziiprofayili ezahlukeneyo ngokupheleleyo. Nxibelelana neqela lethu lentengiso kwaye siya kukunceda ufumane elona lilingana nawe okanye ufumane icandelo olifunayo.
Iipropati zeZakhiwo zeZibalo zoBunjineli
Kwizicelo zokuthwala umthwalo, kuya kufuneka okungaphezulu nje kobukhulu. Itheyibhile engezantsi idwelisa iipropati zecandelo eliphambili ezisetyenziswa ziinjineli xa zigoba kwaye zicheba.

Ithetha ukuthini la manani:
Indawo (A)— Indawo enqamlezileyo yetshaneli. Iluncedo ekubaleni ubunzima bentsimbi iyonke kunye nomthamo womthwalo we-axial.
Ix (Umzuzu wokungabi namandla)— Umlinganiselo wokumelana kwecandelo ekugobeni malunga ne-axis enamandla (xx). Amaxabiso aphezulu athetha imisebe eqinileyo.
I-Sx (iModulus yeCandelo)— Ithathwe kwi-Ix, eli lixabiso olifaka kwiifomyula zoxinzelelo olugobileyo (σ = M/S). Liyiparameter esetyenziswa kakhulu yokulinganisa ubungakanani bemitha phantsi komthwalo ogobileyo.
Ukuba usebenza kwibhokisi ethile yomthwalo kwaye awuqinisekanga ukuba yeyiphi icandelo oza kulicacisa, sithumelele izibalo zakho — iqela lethu lobuchwephesha linokujongisisa kabini kwaye licebise ubungakanani obungabizi kakhulu.
Ukuqonda Ubukhulu beC Channel
Kuyanceda ukwazi ukuba imilinganiselo nganye yenza ntoni xa ukhetha itshaneli. Nantsi inkcazelo emfutshane:
Ubunzulu (d)— Ukuphakama okuthe nkqo kwetshaneli. Eli linani elikwisichazi (C6 × 8.2 lithetha ubunzulu obumalunga nee-intshi ezi-6). Ubunzulu yeyona nto iphambili ekugobeni amandla — iitshaneli ezinzulu zisingatha umthwalo omninzi kububanzi obufanayo.
Ububanzi beFlange (bf)— Ububanzi beeflanges eziphezulu nezisezantsi. Iiflanges ezibanzi zikunika indawo engaphezulu yokudibanisa kwaye ziphucula uzinzo olusecaleni.
Ubukhulu bewebhu (tw)— Ubukhulu bewebhu ethe nkqo. Iiwebhu ezityebileyo zithetha ukuba zinamandla aphezulu okucheba kunye nokumelana ngcono ne-buckling yendawo.
Ubunzima ngenyawo (lb/ft) bukwafanele ukuqwalaselwa — yindlela oqikelela ngayo ixabiso lezinto kunye nobunzima bokuthunyelwa kweodolo yakho.
Umzekelo: Itshaneli ye-C6 × 8.2 inobunzulu obuqhelekileyo obuzii-intshi ezi-6 kwaye inobunzima obuziiponti ezi-8.2 ngenyawo. Intonga yeenyawo ezingama-20 inobunzima obuziiponti ezili-164. Nyukela kwi-C12 × 20.7, kwaye ubude obufanayo beenyawo ezingama-20 bufikelela kwi-414 lbs.
Ubungakanani beSiteshi se-C esiQhelekileyo kunye nalapho sisetyenziswa khona
Ayizizo zonke iisayizi ezifanelekileyo kuyo yonke imisebenzi. Nantsi indlela uluhlu oluqhelekileyo oluhlulwa ngayo ngokwesicelo:
Iitshaneli ezincinci (C3 - C5): Umsebenzi olula
Izibiyeli kunye nee-mounts zezixhobo
Iziseko zoomatshini kunye neegada
Ukwakha iifreyimu ezilula kunye nokusika
Izakhiwo ezincinci zenkxaso
La ngamacandelo alula — kulula ukuwasika nokuwenza, kodwa ayenzelwanga imithwalo enzima.
Iitshaneli eziphakathi (C6 - C8): Indawo emnandi
Izakhelo zesakhiwo kunye neepurlins
Izixhaso zophahla nodonga
Iifreyimu zomzimba wetreyila kunye neloli

Ukuqiniswa kwesakhiwo kunye nokuxhaswa
Xa umthwalo unyuka, uya nzulu ngakumbi. Iitshaneli ze-C12 kunye ne-C15 zijongana nemithwalo enzima yokugoba kwaye zixhaphakile kwizakhiwo zoshishino kunye neeprojekthi zeziseko zophuhliso.
Indlela yokukhetha ubungakanani obufanelekileyo betshaneli ye-C
Akukho mpendulo ifanelekileyo kubo bonke, kodwa nazi izinto ezibangela ukuba isigqibo sithathwe:
1. Iimfuno zomthwalo— Imithwalo enzima ifuna iindawo ezinzima. Qala ngokubala kwakho ukugoba nokucheba, uze ukhethe indawo enobukhulu obaneleyo be-Sx kunye newebhu.
2. Ubude bespan— Iispan ezinde zifuna imijelo enzulu. Ukuba umqadi wakho ufikelela kwiimitha ezingama-20, i-C6 mhlawumbi ayizukuyinqumla — kusenokwenzeka ukuba uya kufuna i-C10 okanye ngaphezulu.
3. Iinkcukacha zoqhagamshelo— Iiflange ezibanzi zenza kube lula ukubopha nokuwelda. Ukuba udibanisa amalungu amaninzi, cinga ngobubanzi beflange ecaleni kobunzulu.
4. Uhlahlo lwabiwo-mali kunye nobunzima— Iinxalenye ezinzima zibiza ngaphezulu ngenyawo kwaye zongeza kwiindleko zokuthumela. Ngamanye amaxesha itshaneli enzulu kancinci, elula ikunika amandla owadingayo ngobunzima obuphantsi kunetshaneli emfutshane, enzima.
Ukuba usebenza kwiseti yemizobo, yithumele kwaye siya kucaphula ubungakanani obuchanekileyo obufunekayo. Ukuba usesekwisigaba soyilo, iqela lethu linokukunceda uqonde ixabiso lokukhethwa kwecandelo.
FAQ
