Ukuntuleka Kodonga Lwekhethini kanye Nokwehluleka Ezakhiweni Ezinezitezi Eziningi

Ukuthuthukiswa kobuchwepheshe be-facade yodonga lwamakhethini kuyaqhubeka nomfutho okhulayo ngenxa yezidingo zezakhiwo ezinezitezi eziningi emadolobheni anamuhla. Izinhlobo ezihlukahlukene zamakhethini odonga lwezinhlelo ziye zasetshenziswa kabanzi ngezinjongo ezihlukahlukene. Kodwa-ke, kanye nezinzuzo, ezinye izinkinga zingase zihlangabezane nazo ngesikhathi sokuphila kwezindonga zamakhethini. Ukuhlukaniswa ngezigaba okuntula ngenxa yemibandela ehlukene kubaluleka ekucaciseni lezi zinkinga. Noma kunjalo, ukushiyeka kungaphenywa ngokuya ngenqubo yempilo yonke yodonga lwekhethini olungaphambili lwewindi, ukusebenzisana kwezingxenye zesistimu kanye nezici zemvelo uma ungathanda ukwenza uhlelo olucabangelayo lokwakhiwa kodonga lwamakhethini akho. Njengomthetho, okokuqala ukubikezela kokuntuleka kuye kwenziwa kukho konke ukuphila kwezinhlelo zodonga lwamakhethini ezitholakalayo ngokucabangela izigaba njengokuklama kwesistimu, umkhiqizo, ukuhlanganisa, ukusetshenziswa nokugcinwa, izinqubo zokulawula. Okwesibili, amaphutha enzeka ezindongeni zamakhethini aphenywa ngokuya ngokusebenzisana kwesakhiwo nezinhlelo zamakhethini odonga lwamakhethini. Isigaba sesithathu sihlanganisa ukuhlaziywa kokuntuleka kwezakhiwo ngokucabangela ngenxa yezinto zangaphandle. Isibonelo, izindonga zamakhethini ezicwebezelayo zazimangalisa lapho ziqala ukwakhiwa, futhi kusukela ngaleso sikhathi amadolobha aseMelika abone ukwakhiwa kwenani elikhulu lezakhiwo zengilazi. Ngokuphakama okukhuphukayo nokubuka okushanelayo, izindonga zamakhethini ezicwebezelisiwe zinezindawo ezifiselekayo zehhovisi, zokudayisa, nezindawo zokuhlala ezishesha futhi zingabizi kakhulu ukuzakha kunezakwabo ezinezindonga. Njengoba izindonga zamakhethini ezicwebezelayo ziguga, nokho, izingxenye zazo eziningi zifinyelela ekupheleni kwezimpilo zazo zenkonzo. Uma ukuvuza nokusalungiswa kuba yizinkinga eziqhubekayo, kungaba nzima ukunquma inkambo engcono kakhulu yokwenza. Izimbangela Zokucindezeleka Nokwehluleka Njengazo zonke izici zokwakha, izindonga zamakhethini e-aluminium zinamaphuzu athile abuthakathaka. Ukwazi ukuthi yini okufanele uyibheke, indlela yokwelula impilo yesevisi yesistimu yodonga lwamakhethini, futhi uma sekuyisikhathi sokugcina umxhumanisi kubalulekile ukuze ugweme ukwehluleka okungase kube nezindleko eziphakeme nokuphazamisayo. Nakuba izinkinga zihluka ngempahla yefreyimu, indlela yokwakha, kanye nohlobo lwe-glazing, kukhona ukukhathazeka okuvamile ochwepheshe bokuklama abakubukayo lapho behlola isimo sodonga lwamakhethini. I-Aluminiyamu ephambukayo inezinzuzo eziningi njengohlaka lwamakhethini odonga, kodwa inobubi obuhlukile bokuchezuka cishe ngokuphindwe kathathu kunensimbi eyenza kumthwalo othile. Ngisho noma inani lokuchezuka lingabeki engcupheni amandla amalungu e-aluminium, kusengaba yingozi ngokuthi ingilazi ingase ikhishwe endaweni. Ukuze kuvikelwe ekuphambukeni okweqile, amamiliyoni akhishwa abe yizimo ezikhulisa isikhathi sendawo sokungaguquki, noma ukumelana komumo othize we-cross-sectional ekucindezelekeni okugoba. Izakhi ze-Wide-flange, njenge-I-beams, zinezikhathi eziphakeme kakhulu ze-inertia, yingakho le phrofayela isetshenziswa kaningi ekwakhiweni kodonga lwamakhethini. Ukuze unciphise ukuchezuka ekuhlanganiseni kodonga lwamakhethini ngaphandle kokwengeza ukujula okweqile kuphrofayela yohlaka, ukuqiniswa kwensimbi kungase kwengezwe kumamiliyoni e-aluminium. Le ndlela ivikela insimbi ekuchayekeni ezakhiweni, kuyilapho isebenzisa izici zayo ezithwala umthwalo. Kodwa-ke, ukungena kwamanzi ohlelweni oluqiniswe ngensimbi nakho kungaholela ekuphambukeni njengoba insimbi igqwala futhi yanda, okubangele ukuthi i-aluminium ikhothamele ngaphandle.
