Glulam as a material is characterized primarily by a good balance between load capacity and dead load. Another strength and advantage over other materials is the relatively simple production of curved elements.
The structure of thin lamellas that are glued to one large section provides the ability to produce curved girders with very little effort. A special form are three dimensionally curved beams. In modern architecture, these forms occur more frequently and can be implemented excellent in timber.
Glulam is limited in width while it is still a raw material. By gluing, cross sections can be produced with a width of up to about 26 cm. Several cross section can be glued together to form a block. With his type of gluing, called block lamination it is possible to produce various sections, for example, hollow or T-shaped sections.
Creativity is required
The production of special types of laminated timber requires detailed knowledge. The cooperation partner Schaffitzel Holzindustrie is a specialist in this field. Curved glue-laminated components have already been used in various projects, whether in complex roof structures or bridges.
The modern timber bridge is characterised by a complex increase of monolithic design. In this case, the bridge body is often curved in plan and side view. Schaffitzel + Miebach are pioneers in the implementation of these forms and can rely on an extensive experience in this field.
Notable examples of the production of complex components of this type include bridges Sneek I and II or s-shaped bridge in Lohmar Aggerbogen. Glulam parts of these structures were made with very large cross sections and multi-axis curvature.
