Speed Skating Hall Erfurt - Gunda-Niemann-Stirnemann-Hall

 Back to Projects list
Arnstädter Straße 53, 99096 Erfurt

Over the existing 400m-ice-plane a supportless hall construction with a span about 85m has been developed, so the hall can be used during the whole year for ice sport, speed skating, ice hockey and other events. We developed the unique form and dimension of the building regarding to the specific inner-city location next to the Thuringian Parliament and a fresh-air-aisle of Erfurt. The choice of wood as the main construction material was conditioned by building physical reasons.

The structure exists of bow-formed frames consisting of two wooden half-frames that are connected at the crest of the building. Both of the bigger frame parts consist of two glued wood twin-frames with a diameter of 1,50 m in height and 0,18 m in width. The space between these frames is filled with distance blocks of glued wood. Behind these blocks the pipes and wires of the building technique are hidden. In the tension area bars of steel with a diameter of 6 cm build the overstressing of the frames.
The foot points are pinned on steel pans.

The bracing of the hall happens between every last segment pair of frames before the 2 roundings that are built by concentric ordered half frames. The distance of the big frames from centre to centre is 8,70 m.

On the inside the roof is built of acoustic trapezoidal sheet. The mineral thermal insulation is covered with punctual anchored 1,5 mm EVA foil. The 3 m glazing running circular round the hall in the plinth area enables the transparency of the building and assures the daylight supply of the hall. The inclination of the glass panels avoids blending and overheating inside the building. The band of roof lights improves the daylight feed additionally.
