Knot element, foldable plate, method for producing a node element and method for repairing or adapting a foldable plate

摘要

The invention relates to a node element (4) for connecting plate elements (3) of a foldable plate (1) at a node (P). The node element (4) comprises a plane node flap (4.1) and a node body (4.2) placed on the top side of the node flap (4.1), which is formed by node grooves (4.3, 12) running parallel to the node flap (4.1) and through a longitudinal axis of the node body (4.2). 4.3a, b, c) is divided into contiguous segments (4.2.1 to 4.2.6). The node grooves (4.3, 4.3a, b, c) are arranged at the same angular distance as corresponding, in the node (P) overlapping plate joints (2) between plate elements (3). Each two segments (4.2.1 to 4.2.6) connected by a node groove (4.3, 4.3a, b, c) are permanently movable along this node groove (4.3, 4.3a, b, c) in the folding direction (R) of the corresponding one Plate joint (2) foldable.
