CA 2293409

The invention relates to a connection between two wooden construction parts (2 and 3). According to the invention, a joint plate (4) is introduced, the base part (5) of said joint plate (4) being connected to the wooden construction part (2) so that it is flush therewith, by means of screws (7). Said joint plate (4) is pushed into a slit (8) in the wooden construction part (3) and the appropriate number of connecting elements (1) are then introduced, passing through the wooden construction part (3) and the joint plate (4). A connecting element of the type used has a boring part (11) at one end and a tool contact part (12) at the other end. The material which is worked off is taken up by a segment with a reduced cross section (14) and corresponding chucking grooves (13). The connecting element can also be secured axially after placement by means of a thread (15) at one end of said connecting element. After placement, the connecting element sits in such a way that it fits perfectly in the self-made bore as a fixing element between the joining plate (4) and the wooden construction part.

Lors de l'assemblage entre deux éléments en bois (2 et 3), il est prévu de placer une plaque d'encoignure (4) dont la base (5) est assemblée bord à bord avec l'élément en bois (2), par l'intermédiaire de vis (7). La plaque d'encoignure (4) est introduite par poussée dans une fente (8) de l'élément en bois (3) et un nombre correspondant d'éléments d'assemblage (1) sont ensuite introduits à travers l'élément en bois (3) et la plaque d'encoignure (4). Un élément d'assemblage de ce type comporte à une de ses extrémités une partie de perçage (11) et à l'autre extrémité, un point de contact d'outil (12). Le matériau enlevé est pris par une section (14) dont la section transversale va en s'amenuisant et par des goujures (13) correspondantes. A une extrémité de l'élément d'assemblage, il est également prévu un filet (15) permettant un maintien axial après la mise en place. Une fois cette mise en place terminée, l'élément d'assemblage (1) fait office de fixation entre la plaque d'encoignure (4) et l'élément en bois (3) et se trouve en ajustement précis dans l'alésage auto-taraudé réalisé.
