One maybe strange question – but I always wanted to get this explained: How does a knot of a stick system work? What are the general challenges and how are they solved?

Question asked by Mr K form D.

Answer: 

The point-knot of the stick system is the most critical point as it’s the one that is responsible for accommodating the movements of the structural system behind as well transferring horizontal and vertical façade loads (gravity, working loaded and wind) to the main structure. Next to this the drainage of the cavity of the system is to be organized, allowing water, which penetrated the outer layer of sealant to be drained to the bottom of the construction.

Accordingly, this point should be carefully checked/solved to avoid the failure of the system as well to keep the drainage level on the same plane so that the water will not penetrate the second and final layer of sealant.
