PCT No. PCT/CH84/00051 Sec. 371 Date Dec. 18, 1984 Sec. 102(e) Date Dec. 18, 1984 PCT Filed Mar. 23, 1984 PCT Pub. No. WO84/04123 PCT Pub. Date Oct. 25, 1984.A spherical node element body is composed of several parts (31, 32, 33) held together by a screw (3), these parts contacting each other in pairs along boundary surfaces (35, 36) lying in a plane containing the geometrical nodal point (6) and along boundary surfaces (37, 38) inclined with respect to this plane and oriented toward the nodal point (6). By indentations at these boundary surface pairs (35/36 and 37/38), open cavities (20, 21) oriented toward the geometrical nodal point (6) are formed on the outside of the body, these cavities receiving in a force-derived and/or shape-mating connection respectively one extension (23) of a framework bar end (24) adapted to such cavity (20, 21). |
