Yintoni ulwakhiwo lolwakhiwo lwesakhelo sentsimbi?
Isakhelo sentsimbi sikholisa ukuqulatha ikholamu ethe nkqo kunye nemiqadi ethe tye ekhutshiweyo, ibotshwe okanye idityaniswe kunye kwigridi yerectilinear.Imiqadi yentsimbi ngamalungu olwakhiwo oluthe tye axhathisa imithwalo esetyenziswa ecaleni kwi-axis yawo.Iikholamu ngamalungu amisiweyo amileyo adlulisela imithwalo ecinezelayo.Ingasetyenziselwa ukwenza i-skeleton yesakhiwo.Ulwakhiwo lwentsimbi yolwakhiwo lwesakhelo ludla ngokuyilwa, luyilwe kwaye lumiswe ngokuhambelana nemigangatho esebenzayo umzekelo Iziko laseMelika loKwakha intsimbi (AISC) kunye neCanadian Standard Association (CSA).Kule nqaku, imiba eyahlukeneyo yesakhiwo sokwakhiwa kwesakhiwo sentsimbi iya kugxininiswa.
Iintlobo zoKwakha isakhelo sentsimbi
Kukho iintlobo ezahlukeneyo zokwakhiwa kwesakhelo sentsimbi ezibandakanya:
1. Ukwenziwa kweNsimbi eqhelekileyo
Ukwenziwa kwentsimbi yesiqhelo kubandakanya ukusika amalungu entsimbi ubude obuchanekileyo kunye ne-welding ukwakha isakhiwo sokugqibela.Le nkqubo yokwakha inokuqhutywa kwisiza ngokupheleleyo esifuna abasebenzi abaninzi.Kungenjalo, ukufumana iziphumo ezingcono kunokwenziwa kwindawo yokusebenzela ngokuyinxenye ukubonelela ngeemeko ezingcono zokusebenza kunye nokunciphisa ixesha lokusebenza.
2. Ulwakhiwo lweNsimbi eBolted
Ngobu buchule, onke amalungu entsimbi yesakhiwo ayenziwa kwaye apeyintwe ngaphandle kwendawo, emva koko ahanjiswe kwindawo yokwakha, kwaye ekugqibeleni afakwe kwi-bolt.Ubungakanani bamalungu olwakhiwo lwentsimbi bulawulwa ngubungakanani belori okanye itreyila esetyenziselwa ukuhambisa izinto zentsimbi.Ngokuqhelekileyo, ubude obuphezulu be-6m m bamkelekile kwilori eqhelekileyo kunye ne-12m yetreyila ende.Ukwakhiwa kwentsimbi ebolisiweyo kuyakhawuleza kakhulu kuba ukuphakamisa amalungu entsimbi endaweni kunye nokufaka iibholithi yiyo yonke imisebenzi ekufuneka yenziwe kwindawo yokwakha.Kuthathwa njengeyona ndlela ikhethwayo yokwakha ngenxa yokuba uninzi lwemveliso lunokwenziwa kwiindibano zocweyo, ngoomatshini abafanelekileyo, ukukhanya, kunye neemeko zokusebenza.
3. Ulwakhiwo lweNsimbi yokuKhanya
Intsimbi yokulinganisa ukukhanya ishidi elicekethekileyo (eliqhelekileyo liphakathi kwe-1-3mm) yentsimbi egobileyo ukuze yenze i-C-sections okanye i-Z-sections.Ixhaphake ngokubanzi kwaye isetyenziselwa ukwakhiwa kwezakhiwo zokuhlala kunye nezakhiwo ezincinci.Izibonelelo ezibonelelwa ngokwakhiwa kwensimbi ye-gauge ukukhanya kubandakanya ukuguquguquka koyilo, isantya esiphezulu sokwakha, esomeleleyo, esilula, esilula ukuhlaziywa kwakhona, Ukulungiswa kwakhona, uMgangatho omhle (ohlala ixesha elide kwaye uphantsi ekugcinweni).
Usetyenziso lweSakhelo seNsimbi
Ulwakhiwo lwesakhelo sentsimbi lukhetho olufanelekileyo kulwakhiwo lwezakhiwo ezahlukeneyo kunye nezakhiwo eziphakamileyo ngenxa yamandla ayo, ubunzima obuphantsi, isantya sokwakha, isakhono esikhulu sokwakha.isakhiwo sentsimbi yesakhelo singasetyenziswa ekwakhiweni kwezi zakhiwo zilandelayo:
Izakhiwo eziphakamileyo, umzobo 4
Izakhiwo zemizi-mveliso, Isazobe sesi-5
Izakhiwo zokugcina impahla, Isazobe sesi-6
Izakhiwo zokuhlala, Isazobe sesi-7
Ulwakhiwo lweXeshana, Isazobe sesi-8
Izinto eziluncedo kuLwakhiwo lweSakhelo seNsimbi
Isebenza ngeendlela ezininzi ngendlela emangalisayo
Indawo intle
Uzinzo
Iyafikeleleka
Ihlala ixesha elide
Yakha ngokukhawuleza kwaye kulula
Amandla aphezulu
Ubunzima obuphantsi
Ukukwazi ukuhamba imigama emikhulu
Ukuziqhelanisa nalo naluphi na uhlobo lwemilo
I-Ductility;xa iphantsi kwamandla amakhulu, ayisayi kuqhekeka ngequbuliso njengeglasi, kodwa igobe kancinane iphume kwimo.
