Abstract (en)
[origin: WO8404123A1] A spherical node element is comprised of a plurality of parts (31, 32, 33) held by a screw (3), said parts touching each other at boundary surfaces (35, 36) located in a plane containing the geometrical nodal point (6) and touching each other one by one at boundary surfaces (37, 38) inclined with respect to said plane and orientated towards the nodal point (6). Recesses arranged in those pairs of boundary surfaces (35/36 and 37/38) enable the formation on the outer side of the element of open cavities (20, 21) orientated towards the geometrical nodal point (6); each of those cavities receives by adherence and/or locking a heel of a framework bar end (24) which is adapted thereto (20, 21).
