The seele GmbH has enclosed Strasbourg’s railway station in a glass bubble.
Everything under a single roof. This was the task to be solved when linking Strasbourg’s historic railway station with the surrounding taxi stands and bus and street car stops. The seele company, located in Gersthofen, Germany, accepted the challenge and devised an ingenious solution. These façade specialists constructed a glass structure, designed by French architect Jean-Marie Duthilleul, over the terminal building. The design ensured an unimpeded view of the existing railway station while making for maximum integration.
This glass “porch”, 120 meters long and covering 6,000 square meters, now holds a protective hand over Strasbourg’s central station. The primary steel structure bearing the glass dome comprises 16 main arches set at nine-meter intervals. Horizontal secondary braces, the so-called Fink trusses, are positioned between the arches and spaced at four and a half meters. seele’s team used aluminum abutments to attach vertical T-beams made of steel. The profiles were cut on a TRUMPF TruLaser 3040. “We had to cut steel, stainless steel and aluminum to specific profiles. The gauges ranged from two to 20 millimeters and the batches were small. The single cutting head strategy and the automatic nozzle changer in the TruLaser 3040 were decisive factors when it came to working the components economically,” emphasizes production manager Frank Zwibel. www.seele.com
