Concept: As a canopy for a church building in Aachen, glass tiles were designed by 3*5 m as a self stabilizing system.
Glass is suitable as a construction material by using it in a way, that glass panels can be assembled by linear joints and tilted angles, which allow the glass to be used as a bearing members (Fig 01,02,03, Isometric, Overall view of the canopy, Bottom view ) .
Supporting Structure: The system is consist of six inclined glass panels. the outer two V forms were the ones which is supported by round tubes providing a 5 m self-supporting span.
To assess the safety risk in case of failure, different tests carried out, which led to details development by adding safety ropes to secure the laminated safety glass in case of simultaneous failure of the bonding connections (Fig 04,05. Canopy view, Canopy side-view ) .
Construction: The glass panels were rested on L shaped brackets, which were screwed to the supporting connections. Due to the bad local conditions, he joints were glued with special high performance silicone.
The glass panes were rested on V shape support arms, which were clamped to stainless steel tubular supports.
A problem came up from the steel structure tolerances, what make an additional safeguard for the failure case is a must (Fig 06,07, V shape glass panels, V shape connection ) .
Glass: The glass panes were made of 2*10 mm float glass forming laminated safety panel, the size of the panels were up to 5.70*1.32 m.
Due to the large size of the panels, lifting equipments were required (Fig. 08,09, Glass plate detail, Final detail).
