Izinzuzo Of Cold Yakheka Welded Structural

Izinzuzo Of Okubandayo Okwakhiwa Welded Structural Isithombe Esifakiwe

Incazelo emfushane:

Lapho kwakhiwa izakhiwo nezakhiwo, ukukhethwa kwezinto zokwakha kudlala indima ebalulekile ekuqinisekiseni ukuqina namandla omkhiqizo wokugcina. Enye impahla ethandwayo embonini yezokwakha insimbi yesakhiwo ehlanganisiwe ebandayo. Le nto emisha inikezela ngezinzuzo eziningi, okwenza kube ukukhetha kokuqala kumaphrojekthi amaningi wokwakha.

Thumela i-imeyili kithi

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Insimbi eyakhiwe ebandayo ikhiqizwa ngokugoba nokwenza amashidi ensimbi noma amakhoyili ekamelweni lokushisa ngaphandle kokusebenzisa ukushisa. Inqubo ikhiqiza into enamandla, ehlala isikhathi eside kunensimbi eyakhiwe ngokushisa. Le nsimbi eyakhiwe ngendlela ebandayo inikeza izinzuzo ezimbalwa ezibalulekile lapho ishiselwe ndawonye ukuze yakhe izingxenye zesakhiwo.

Enye yezinzuzo eziyinhloko zekubanda kwakheka ashiselwe isakhiwo insimbi isilinganiso sayo esiphezulu samandla nesisindo. Lokhu kusho ukuthi inikeza amandla aphakeme ngenkathi inesisindo esincane, okwenza kube lula ukuyiphatha nokuthutha ngesikhathi sokwakhiwa. Ukwengeza, amandla aphezulu ensimbi eyakhiwe ngendlela ebandayo anika amandla imiklamo yesakhiwo emincane futhi ephumelelayo eyenza isikhala futhi inciphise ukusetshenziswa kwezinto ezibonakalayo.

Enye inzuzo ephawulekayo yensimbi yesakhiwo esakhiwe ngokubandayo ukufana kwayo nokuvumelana. Inqubo yokubumba ebandayo iqinisekisa ukuthi insimbi igcina izakhiwo zemishini ezingaguquki kuyo yonke into, okuholela ekusebenzeni okubikezelwe nokuthembekile. Lokhu kuvumelana kubalulekile ekuqinisekiseni ubuqotho besakhiwo nokuphepha kokwakhiwa kokugcina.

Ngaphezu kwamandla nokungaguquguquki, insimbi ebandayo ye-Formed Welded Structural inikeza ukunemba okuhle kakhulu kwe-dimensional nokunemba. Inqubo yokubumba ebandayo ivumela ukubekezelelana okuqinile kanye nokubumba okunembile, okuqinisekisa ukuthi izingxenye zesakhiwo zihlangana ndawonye ngaphandle komthungo phakathi nokuhlanganiswa. Leli zinga lokunemba libalulekile ekuzuzeni umkhiqizo oqediwe wekhwalithi ephezulu, okhangayo obonakalayo.

Ukwengeza, insimbi ebandayo eyakhiwe nge-Welded Structural steel inemisebenzi eminingi futhi ingenziwa ngendlela oyifisayo ukuze ihlangabezane nezidingo ezithile zephrojekthi. Ingabunjwa kalula futhi ibunjwe ibe yizinhlobonhlobo zamakhonco kanye nokucushwa, okuvumela ukudalwa kwemiklamo yesakhiwo eyinkimbinkimbi. Lokhu kuguquguquka kuyenza ifaneleke ezinhlobonhlobo zezicelo kusukela ekwakhiweni kwezindawo zokuhlala kuya ezikhungweni zezimboni.

Ukusetshenziswa kwensimbi ebandayo ye-Formed Formed Welded Structural nakho kunomthelela ezenzweni zokwakha ezisimeme. Imvelo yayo engasindi inciphisa umthwalo ophelele esisekelweni nesakhiwo sokusekela, okuholela ekongeni kwezindleko okungaba khona kanye nezinzuzo zemvelo. Ukwengeza, ukugaywa kabusha kwensimbi kwenza kube ukukhetha okuvumela imvelo kumaphrojekthi wokwakha.

Kafushane, insimbi ebandayo eyakhiwe nge-Welded Structural inikeza izinzuzo eziningi ezikwenza kube ukukhetha okukhangayo kumaphrojekthi wokwakha. Isilinganiso sayo esiphezulu samandla nesisindo, ukungaguquguquki, ukunemba, ukuguquguquka nokusimama kuyenza into ebalulekile yokudala izakhiwo ezihlala isikhathi eside, ezisebenza kahle. Njengoba imboni yezokwakha iqhubeka nokuthuthuka, insimbi ebandayo Esakhiwe Ngokushiselwe izodlala indima ebalulekile ekulolongeni izakhiwo nengqalasizinda yesikhathi esizayo.
