Izidibanisi zomthi ezenziwe ngobunjineli zakhiwe ngokwahlukileyo kunezo zidityanisiweyo zomthi oqinileyo, kwaye ngenxa yokuba kusetyenziswa izinto ezincinci, zitsha ngesantya esikhawulezayo ngexesha lokutsha kwendlu.Ngenxa yesi sizathu, izibane ezilinganiselweyo zomlilo ezisetyenziswa kwiisilingi ezinjalo kufuneka zivavanywe ukuqinisekisa ukuba ziyahlangabezana nokona kuncinane. Imfuno yemizuzu engama-30.
I-National Building Council (NHBC), i-UK umboneleli ohamba phambili weewaranti kunye ne-inshurensi yokwakhiwa kwekhaya elitsha e-UK, uthe kunyaka odlulileyo kufuneka kuthathwe amanyathelo okuqinisekisa ukuba ukukhanya okuchasene nomlilo kuhambelana nezindlu ze-i-Joists ezisetyenziselwa ulwakhiwo 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 nofakelo lwemizuzu engama-30/60/90, iimvavanyo ezintathu ezahlukeneyo ezingama-30. imizuzu, imizuzu engama-60 kunye nemizuzu engama-90 iya kuqhutywa kunye nezibane ezifakwe kwisilingi ehambelanayo / uhlobo lolwakhiwo lomgangatho kwaye iimvavanyo ezifanelekileyo ziya kwenziwa Ubungqina kufuneka bunikwe.
