Title: NODE ELEMENT FOR CONNECTING CONSTRUCTION ELEMENTS, IN PARTICULAR SUPPORT STRUCTURE ELEMENTS OR PROFILES
Abstract:
The invention relates to a node element (1) for connecting construction elements (10), in particular support structure elements or profiles, wherein the node element (1) is arranged in the area of the connection of the construction elements (10) and can be fastened to the construction elements (10) to be connected. The node element (1) has at least two each mutually associated connecting elements (2, 3) that can be separated from one another, which connecting elements in the region of a connecting surface (4) that is arranged inclined at an angle (α, β) to the outer contour of the connecting elements (2, 3) are formed to match one another and can be secured against each other in a force-fitting manner. The two mutually associated connecting elements (2, 3) are rotatable relative to one another about an axis of rotation (5) perpendicular to the connecting surface (4), and by means of at least one force-fitting connecting device (11, 17) can be detachably fixed to one another in the respectively required rotational position. The force-fitting connecting device (11, 17) substantially acts parallel to the axis of rotation (5) between the two connecting elements (2, 3).
