Objectives and work programme
The steel-glass roof system can be used for roofing in courtyards and city-centre shopping streets, and is therefore well suited for renovating and upgrading existing buildings and structures. As it allows for custom shapes, the steel-glass roof system can be adapted to suit the requirements of the construction project.
The new and innovative aspect of this glass system is the logical integration of the room-enclosing glazing in the roof support system by way of a targeted load transfer via the glazing itself. The steel-glass roof system is designed as a spatial framework, whereby the upper flange is formed by the room-enclosing composite safety glass. The support structure consists of the composite safety glass, nodes positioned on the edges of the panes, slim struts and thin tension elements. This system concept allows the steel substructure to be reduced to a minimum. This structure, which is designed without any additional components, achieves a high degree of light transmission with low construction costs. It allows for a variety of roof shapes, with a span width of up to 25 m.
