The Influence of Glued Dowel Joints Construction on the Bending Moment Resistance
Keywords:particleboard, corner joint, dowel, bending moment resistance, mode of failure, fracture zone.
Although doweled joints are widely used in the wide constructions of case furniture, little information is available about additive effects of distance between the centers of dowel holes and nominal distance between dowel and the edge of a detail on the bending strength of dowel joints. This research was carried out to obtain background information concerning the bending moment resistance of double-dowel joints in particleboard. The specimens were constructed from particleboard of 16, 8 mm in thickness produced at J/V “Girių Bizonas” and joined with glued multigroove beech dowels of 8, 10 mm in diameter. The results indicated that the resistance of single-dowel corner joints significantly increase when the distance between the centers of dowel holes and nominal distance between a dowel hole and edge of a member is rational. In this study optimal distance between the centers of dowel holes and nominal distance between dowel and the edge of a detail was obtained.
