This paper presents a proposal for updating and expanding the teaching of
technical university students concerning the subject of roofs. Through the
analysis of Polish textbooks and teaching studies, a lack of information on
retractable roofs was identified. As a consequence, a lecture was prepared to
fill this gap and presented to students of the Faculty of Civil Engineering and
to teaching staff of the Silesian University of Technology. The main components
of the lecture are presented in this article. Furthermore, a discussion was
undertaken to analyse the possibilities of incorporating new content (in the form
of supplementary material) into the currently run courses as well as into optional
classes such as student workshops and optional facultative courses.
This work presents retractable roofs of new designs based on class II mechanisms. Firstly, roofs that are currently in existence were analysed in terms of the mechanisms involved in their construction. Then, the possibility of constructing a roof based on the variety of quadruples in which all links are joined with roof panels was investigated. The boundary conditions that have to be fulfilled by such a construction were specified. Ultimately, research models were constructed with the use of construction solutions similar to those applied in buildings currently in existence.Keywords: membrane roof, retractable roof, mechanisms class II Streszczenie W artykule przedstawiono propozycję nowych rozwiązań ruchomych dachów w oparciu o mechanizmy klasy II. W pierwszej kolejności przeanalizowano istniejące zadaszenia pod kątem występujących w ich budowie mechanizmów. W kolejnym etapie sprawdzono możliwość skonstruowania zadaszenia opartego na różnego rodzaju czworobokach, których wszystkie człony połączone są z panelami dachowymi. Określono warunki brzegowe, które musi spełniać tego typu konstrukcja. Ostatecznie zbudowano modele badawcze, stosując rozwiązania konstrukcyjne analogiczne do rozwiązań używanych w istniejących obiektach.Słowa kluczowe: dachy membranowe, ruchome dachy, mechanizmy klasy II 6
