The invention relates to a connecting node (10, 20) for constructing a three-dimensional framework (100), in particular a geodetic structure, wherein the connecting node (10, 20) has at least one connecting arrangement for connection by way of a definable number of (n) of basic structural elements (3) attached to the respective connecting node (10, 20) with other identical connecting nodes (10, 20). It is provided that the connecting node (10, 20) is formed as a disk (4, 6) having a predefinable number (n) of keyholes (1n), with each of the keyholes (1n) being penetrated by a connecting means (5) and engaging with a receiving element (3A) attached on the basic structural elements (3n), so that each basic structural element (3n) is rotatably supported in the formed first connecting arrangement (5, 3A) and can be pre-adjusted and subsequently attached at arbitrary predefinable angles. The invention is also directed to a three-dimensional framework (100), in particular a geodetic structure, with a plurality of configurable basic structural element (3n), which are secured between the connecting nodes (10, 20) so as to form the three-dimensional framework.
