Dübelverbindungen

Dübelverbindungen, often translated as dowel joints or peg joints, are a fundamental method in woodworking and construction for joining two or more pieces of material. The core principle involves inserting a cylindrical pin, known as a dowel, into pre-drilled holes in each component. These dowels are typically made of wood, metal, or plastic and act as a mechanical fastener, reinforcing the connection.

The process begins with accurately measuring and marking the joint locations. Holes are then drilled into each piece, ensuring they are precisely aligned and of the correct diameter to snugly accommodate the dowel. Wood glue is usually applied to the dowels and the inside of the drilled holes before assembly. This adhesive provides the primary holding strength, while the dowel offers internal support and prevents shear stress from separating the joined pieces.

Dübelverbindungen are valued for their strength, durability, and aesthetic appeal, as they can be largely concealed. They are commonly used in furniture construction, cabinet making, and the assembly of timber frames. Variations exist, including blind dowels (where the dowel is not visible from the exterior) and splined dowels, which have a slightly flattened or grooved surface to improve glue adhesion. The effectiveness of a dowel joint relies heavily on the precision of the drilling and the quality of the glue used.
