Solid Wooden Dome

A flat dome of curved plywood stretches over the synagogue in Regensburg planned by Staab Architekten. It is square in plan and has a span of 12.13 m. The shell consists of 20 individual segments, which are triangular in plan and meet in the centre. The double-curved cross laminated timber segments are available as five different types. The elements have a maximum size of 2.35 × ­ 9 m and consist of seven crosswise glued boards. The shell is framed by four circular, rolled steel arches, which are clamped in the corners in round steel tube supports. The 5.5-m-long ­supports rest on the synagogue ­gallery; horizontally, they are ­also supported by the flat ­concrete roof. The elements of the double-curved cross ­laminated timber shell were ­woven and glued crosswise on an empty frame by Züblin Timber, pressed with vacuum pressure and cut with a 3D robot. On the construction site, the ­panels were fitted into the previously mounted steel frame using ­a central scaffolding tower, ­assembled and braced with ­the formwork.
