Tongue and groove

The tongue and groove connection and the tongue and groove are wood compounds, mainly board-like components are plugged together at their edges.

• Wherein the tongue and groove connection, both components to be connected at the edges each have a groove into which the third connecting component as a so-called spring is inserted. The connection is positively perpendicular to the board level.
• In the tongue and groove, a spring is working at half the width of the edge of one of the two components to be connected.

Function

Springs and bungs are too thin to be sufficiently resistant to bending. Your shear strength is sufficient to transfer lateral forces from board to board ( under load only a board bearing the surrounding boards with ).

Application

Both connection types are classic wood joints for doors, walls, floors and ceilings made of wood boards. Today, plastic boards are used (for example, for laminate floors), it outweighs the tongue and groove.

Applications of this type of mold closure and during the creation of the walls and larger sheets of the same components, which are not wooden. Insulation boards are not only held each other by means of a tongue and groove connection. There is also a wind denser junction generated as with just edged plates. Concrete brick and precast concrete parts shall also be plugged form fit together to partially or completely kicking the mortars can.

The engineering used in shaft-hub connection by means of feather emerged from the tongue and groove connection.
