Özet:

In this study, the effects of wood species, adhesive types and pressing direction on diagonal tensile strength performance in the wooden window corner joints with single or double mortise and tenon were examined. Specimens of single and double mortise and tenon corner joints were prepared from Scotch pine (Pinus Sylvestris Lipsky) and Uludağ fir (Abies bornmülleriana) woods with this objective. PVAc-D3 and PVAc-D4 adhesives were used to join the mortise and tenon corner joints. The joining points were pressed from the edge and from the surface and edge. A total of 160 each specimens were prepared and the diagonal tensile strength test was made according the principles given in ISO 6237. In conclusion, it was determined that the highest diagonal tensile strength performance was in the double mortise and tenon corner joint specimens from Scotch pine pressed from the edge and from the surface with PVAc-D4 adhesive and the lowest diagonal tensile strength performance was in the single mortise and tenon corner joint specimens from Uludağ fir pressed from the edge with PVAc-D3 adhesive
