Junction for connection and assembly of truncated conical-pyramidal geometric shapes for multi-directional elements of three-dimensional structures, comprises a rigid envelope of truncated conical-pyramidal shape whose small base is continuous and whose large base is disposed on the perimeter of a polygon on the flat sides of the pyramid and on the internal or external surfaces of the envelope or on both, structural elements can be secured in known ways. The small base surrounds a hole for the passage of securement or assembly devices. A plurality of such joints can be assembled, with their small bases adjacent each other, to form a composite joint. The structure is useful for the construction of metallic three-dimensional structures.
