Izidibanisi zomthi ezenziwe ngobunjineli zakhiwe ngokwahlukileyo kunezo zidityanisiweyo zomthi oqinileyo, kwaye ngenxa yokuba kusetyenziswa izinto ezincinci, zitshisa ngokukhawuleza ngexesha lokutsha kwendlu.Ngenxa yesi sizathu, izibane ezilinganiselweyo zomlilo ezisetyenziswe kwiisilingi ezinjalo kufuneka zivavanywe ukuqinisekisa ukuba ziyahlangabezana noko kuncinane. Imfuno yemizuzu engama-30.
I-National Building Council (NHBC), i-UK ehamba phambili yomboneleli weziqinisekiso kunye ne-inshurensi yokwakhiwa kwekhaya elitsha e-UK, yathi kunyaka ophelileyo ukuba amanyathelo kufuneka athathwe ukuze kuqinisekiswe ukukhanya okuchasene nomlilo kuhambelana nezindlu ze-i-Joists ezisetyenziselwa ukwakhiwa olutsha.
Uphononongo olufanelekileyo okanye uvavanyo lwezakhiwo zomgangatho ezichazwe kwi-I-beam-based kunye neesilingi kunye nezibane ezikhankanyiweyo ezichaziweyo ziyafuneka ukucacisa ufakelo oluvunyiweyo.
Ngaba uzijongile izibane zomlilo ezireyithiweyo ozibalulileyo kwaye uzifakile zineengxelo zovavanyo ezibonisa ukuba zikhuselekile ukuba zisetyenziswe kwisilingi echaziweyo ye-I-beam? Ngoku lixesha lokujonga.
Ukuntsokotha kovavanyo apho izibane ezireyithwe ngumlilo zichanekile kufuneka ziqondwe ukuze kuthotyelwe imimiselo emalunga namaxesha asezantsi okuxhathisa.
Uvavanyo olunye lwexesha elinye aluthethi ukuba imveliso ifanelekile kuzo zonke izicelo zemizuzu engama-30/60/90. Ukuze imveliso ihambelane ngokupheleleyo kulo lonke ukufakelwa kwemizuzu engama-30/60/90, iimvavanyo ezintathu ezahlukeneyo ezingama-30. imizuzu, imizuzu engama-60 kunye nemizuzu engama-90 iya kuqhutywa kunye nezikhanyiso ezifakwe kwisilingi ehambelanayo / uhlobo lolwakhiwo lomgangatho kwaye iimvavanyo ezifanelekileyo ziya kwenziwa Ubungqina kufuneka bunikwe.
