ABSTRACT:
Constructive element (1), such as a profile or a grid or another adequate constructive element, where said constructive element (1) is formed beginning with a sheet whose thickness is fundamentally constant; the cross-section of said constructive element includes at least one unfolded region (2) defined between two ends of said cross-section; said unfolded region (2) includes a plurality of cuts that define a regular pattern along the constructive element (1); said unfolded region (2) is produced when a tractional force is applied to their respective ends; said constructive element (1) is characterized because said unfolded region includes at least one element rotated essentially in 180° (2.2) with regard to the rotation it had prior to the application of said tractional force; said at least one rotated element (2.2) is joined to at least one element that does not rotate (2.1), by means of conveniently defined linking lines (2.3).
