Description

Die Keilwirkung wird entweder durch ballige oder konische Ausbildung der Seitenflächen 7 des Keiles erreicht.The wedge effect is either spherical or achieved conical design of the side surfaces 7 of the wedge.

Zum Einschlagen der Keile 5 sind die Bauelemente 1 an den Stirnseiten mit von den Verbindungsmitteln an den Stirnseiten ausgehenden, über einen Teil der Länge des Bauelementes sich erstreckenden Einschnitten 6 versehen, deren Breite der Breite der hinterschnittenen Nuten im Bereich der Nutlippon 8 entspricht. Der Einschnitt verschwindet dadurch in den Längsnuten 2 der Bauelemente. Durch Abstimmung der Länge der Keile 5 auf den zwischen zwei sich gegenüberliegenden Längsnuten verbleibenden Stegabstand ist die Verkeilung der Verbindung kaum bemerkbar.To drive in the wedges 5, the structural elements 1 are attached to the end faces with the connecting means Notches 6 emanating from the end faces and extending over part of the length of the component provided, the width of which corresponds to the width of the undercut grooves in the area of the Nutlippon 8. the As a result, the incision disappears in the longitudinal grooves 2 of the components. By tuning the length of the Wedges 5 on the web spacing remaining between two opposing longitudinal grooves is the wedging barely noticeable of the connection.

Der an der Stirnseite mit der Verbindungsleiste 3 angeordnete Einschnitt 6 verläuft quer zu dieser Verbindungsleiste, während der Einschnitt an der mit der hinterschnittenen Nut 2 versehenen Stirnseite in gleicher Richtung wie die hinterschnittene Nut verläuft. Dadurch wird verhindert, daß beim stirnseitigen Verbinden zweier Bauelemente die beiden Einschnitte an den Stirnseiten aufeinanderkommen.The incision 6 arranged on the end face with the connecting strip 3 runs transversely to the latter Connecting strip, while the incision on the end face provided with the undercut groove 2 in the same direction as the undercut groove. This prevents the frontal Connect two components the two incisions come together on the end faces.

The invention relates to a component with a square shape, the width of the incisions corresponds to the width of the groove opening according to the cross section for assembling lattice frames. The incisions thus coincide with the most in particular for the production of building game longitudinal grooves of the components without affecting the other components, which are designed as a connecting means for connecting but the function of the longitudinal grooves as a connecting identical connection to other components. Through these measures, four side surfaces and the incisions on one end face are barely recognizable, especially if an undercut groove and on its other 40 the length of the wedges driven in have an integrally molded undercut connecting strip corresponding to the groove shape between the two opposing longitudinal grooves on the end face - the remaining web spacing are adjusted,

Such components made of plastic incision on the with the undercut groove are known as the building blocks of construction kits. 45 provided end face in the same direction as the These components are connected by undercut grooves. This prevents pushing-in the undercut connecting strip in such a way that home connecting two structural elements at the front undercut grooves on the side surfaces and mente the two incisions are aligned and on a frontal part of the component.
