In modern timber construction, wooden beams and joints are secured with screws and metal connectors. Notches, overleaves and other traditional wooden joints are real eye-catchers and embody the craftsmanship of carpenters – but from today’s technical point of view they have the following disadvantages:
- The cross-section of the wood is weakened (you remove part of the supporting beam)
- The weakening is often exactly at the critical, particularly stressed points
- The flat end-grain woodcuts and joints are particularly critical for water accumulation
As beautiful as the old connections are: from a static and technical point of view, we have much better means at our disposal today: instead of hand-forged nails, there are now special wood screws for every type of connection!
