Transversal tension reinforcement
for timber components
With certain components, planned transverse tensile stress cannot be avoided. Particularly in the case of curved gable roof beams made of glulam, the low strength of the wood across the grain can quickly be exceeded. Here, reinforcements must be provided to ensure the stability of the component. A proven method are reinforcing elements such as internal pin-shaped or external surface-shaped reinforcements.
Transverse tension reinforcement with
fully threaded screws and threaded rods
An effective possibility for transverse tensile reinforcement are fully threaded screws or pre-drilled, screwed-in threaded rods with wood screw thread.
These have proven their worth in practice and are also suitable for the renovation of components subject to transverse tensile stress where cracking has occurred. A basic requirement for reinforcing elements is a continuous bond between the reinforcing element and the wood. In addition, the reinforcing element should have sufficient rigidity to prevent large cracks from forming.
The latest design standards recommend that components or component areas subject to transverse tensile stress (notches, openings, transverse connections) should always be reinforced.
