“…Simek and Sebera [20] have suggested θ 3 = 15° for spruce plywood panels. Such prismatic joints can only be assembled or disassembled along one assembly direction In addition to the finger joints resistance to shear and compressive forces, dovetail joints can, without adhesive bonding, also resist bending moments and traction forces which are not parallel to .…”

ABSTRACT:Automatic joinery has become a common technique for the jointing of beams in timber framing and roofing. It has revived traditional, integral joints such as mortise and tenon connections. Similarly, but only recently, the automatic fabrication of traditional cabinetmaking joints has been introduced for the assembly of timber panel shell structures. First prototypes have used such integrated joints for the alignment and assembly of components, while additional adhesive bonding was used for the load-bearing connection. However, glued joints cannot be assembled on site, which results in several design constraints.In this paper, we propose the use of dovetail joints without adhesive bonding, on the case study of a timber folded plate structure. Through their single-degree-of-freedom (1DOF) geometry, these joints block the relative movement of two parts in all but one direction. This presents the opportunity for an interlocking connection of plates, as well as a challenge for the assembly of folded plate shells, where multiple non-parallel edges per plate must be jointed simultaneously.

“…A study of the bending stiffness of a through dovetail joint for plywood panels has also been reported. Again, friction is implemented in the 3D-solid finite element model, but the studied orthotropic material, used for furniture, was only considered in its elastic stage as the final displacement was limited to 2 mm [10]. Robeller et al [6] presented a linear interlocking connection of plates for the in-space assembly of folded plate shells.…”

Folded-plate structures provide an efficient design using thin laminated veneer lumber panels. Inspired by Japanese furniture joinery, the multiple tab-and-slot joint was developed for the multi-assembly of timber panels with non-parallel edges without adhesive or metal joints. Because the global analysis of our origami structures reveals that the rotational stiffness at ridges affects the global behaviour, we propose an experimental and numerical study of this linear interlocking connection. Its geometry is governed by three angles that orient the contact faces. Nine combinations of these angles were tested and the rotational slip was measured with two different bending setups: closing or opening the fold formed by two panels. The non-linear behaviour was conjointly reproduced numerically using the finite element method and continuum damage mechanics.
