Abstract

Przedmiotem zgłoszenia jest przedstawiona na rysunku belka ażurowa wykonana na bazie dwuteownika gorącowalcowanego, charakteryzuje się tym, że zbudowana jest z górnej części i dolnej części, zaś każda z części budowana jest z połowy przeciętego przez środnik dwuteownika gorącowalcowanego innego typu wzdłuż krzywej cięcia. Górna część jest wykonana z dwuteownika gorącowalcowanego szerokostopowego o zbliżonych momentach bezwładności względem obu osi głównych przekroju, a dolna część wykonana jest z dwuteownika gorącowalcowanego o wąskich półkach, a więc o momencie bezwładności względem poziomej osi głównej przekroju znacznie większym od momentu bezwładności względem pionowej osi głównej przekroju, a ponadto krzywa cięcia jest tak wyznaczona, aby po złączeniu dwóch części belki pomiędzy częściami uzyskać otwory w środniku przebiegające wzdłuż belki.
