Integral attachment, the joining of parts through their form rather than additional connectors or adhesives, is a common technique in many industry sectors. Following a renaissance of integral joints for timber frame structures, recent research investigates techniques for the attachment of timber plate structures.
This video demonstrates the development of a folded surface structure with double through-tenon joints. The joints allow for the rapid, precise and fully integral assembly of structures with two interconnected layers of cross-laminated engineered wood panels. The shape of the plates and the assembly sequence allow for an attachment without additional connectors or adhesives.
We demonstrate how we design the structure based on constraints, which result from the joint assembly and fabrication with a 5-axis CNC milling machine. The analysis of constraints, generation of 3D geometry and machine code is realized through the development of customized algorithms using a CAD application programing interface.
