Izakhiwo zesakhiwo sensimbi zinezinqubo ezilula zokwakha, ukusimama okuhle kakhulu kwesakhiwo nokusebenza kokuzamazama komhlaba, okuzuze ukuqashelwa kabanzi emphakathini. Enkathini ekhuthaza ukwakhiwa okuluhlaza okuvumelana nemvelo, ukwakhiwa kwezindlu zensimbi sekuphenduke inkambiso engenakugwemeka kuzo zombili izindawo zasemakhaya nasemadolobheni. Izakhiwo ezinjalo zihlanganiswa ezingxenyeni ezihlukahlukene zensimbi. Ngakho yiziphi izinkinga ezibalulekile okufanele zibhekiswe ngesikhathi sokwakhiwa ukuze kuqinisekiswe ikhwalithi nokuzinza kwesakhiwo sezindlu zensimbi?

Cacisa ukwakheka kwesakhiwo sokuqala, bese ukhetha izindawo zokuxhuma ezinengqondo nezinhlobo zokuxhuma phakathi kwesakhiwo sensimbi esisanda kwakhiwa kanye nesakhiwo sokuqala, ukuze uvimbele imithwalo evela esakhiweni sensimbi ukuthi ingalimazi isakhiwo sokuqala.

Hlela imishayo yensimbi eyisisekelo neyesibili ngokuhambisana nezakhiwo, umhlobiso wangaphakathi kanye nemiklamo yokufaka i-electromechanical ye-attic, ukugwema noma ukunciphisa umonakalo wesibili esakhiweni sensimbi ngesikhathi sokuhlobisa kanye nemisebenzi yokufaka.

Amashubhu ensimbi yesikwele, insimbi yesigaba esingenalutho neminye imikhiqizo yensimbi engenalutho ayinconywa. Izindawo zabo zangaphakathi azikwazi ukugqokwa kalula ngopende ophikisana nokugqwala. Ezifundeni ezisenyakatho, ukuguquguquka kwezinga lokushisa kuholela emanzini ajiyile ngaphakathi kwensimbi engenalutho, okubangela amabala okugqwala angcolisa usilingi olumisiwe kanye nezindonga zodonga. Ezimweni ezimbi kakhulu, lokhu kuzodala izingozi zokuphepha.

Chaza isakhiwo esithwala umthwalo sesakhiwo sensimbi futhi uklame indlela ecacile, emfushane yokudlulisa amandla. Izakhiwo zensimbi zithambekele ekudlidlizeni okusobala ngaphansi komthwalo, ngakho-ke ukubala okunembe kwesakhiwo nokuhlaziya kuyadingeka ukuze kulawulwe ngokuqinile ukuwohloka kwesakhiwo kanye nemvamisa yokudlidliza. Lokhu kugcina ukubukeka okuhlanzekile kwesakhiwo, kuqeda ukukhala okubangelwa imisebenzi yabantu, kuvimbela ukwehluleka kokukhathala kwe-shear okubangelwa ukuzwakala kwe-resonance, futhi kuqinisekisa ukuphila okunethezekile.

Ukukhethwa kwezinto zensimbi (insimbi yesiteshi, i-I-beam): Ukucaciswa okujwayelekile kufaka phakathi i-10#, 12#, 14# kanye ne-16#. Ngaphandle kokucaciswa okukhethiwe, insimbi evamile kazwelonke inconywa kakhulu, njengoba inekhwalithi ephezulu yezinto ezibonakalayo nokunemba kobukhulu uma kuqhathaniswa nensimbi engajwayelekile. Insimbi engajwayelekile ifaka ubulukhuni obuphezulu, i-brittleness kanye ne-ductility ephansi, okwenza kube nzima ukusika nokubhoboza.
-
Ngaphambi kokulungisa insimbi yesiteshi, sebenzisa upende ophikisana nokugqwala ohlangothini oluxhunywe odongeni. Zonke ezinye izindawo zizopendiwa ngemva kokuqedwa kokushisela; ukudweba ngaphambi kwesikhathi kuzobeka engcupheni ikhwalithi yokushisela.
-
Ngesikhathi sokwakhiwa kwesakhiwo sensimbi, imishayo ye-I kanye nensimbi yesiteshi kufanele isebenzise ukucaciswa okufanayo. Ukungena okugcwele kwe-welding kuyimpoqo. Izikebhe ezinkulu ezithwala umthwalo kufanele zenziwe ngezingxenye zensimbi ezihlangene; Ukuxhumanisa phakathi kwe-span kwama-keels amakhulu ngokushisela akuvunyelwe ngokuphelele.
