Especially shaped bendable section with one or two segmented surfaces running lengthwise and essentially made up of a sequence of rectangular and/or trapezoidal elements or tongues to which, depending on the section being U, C or double-C shaped, one or two flat laminar elements (13) or (13") are coupled so that they are positioned alternatively between the internal face of one tongue and the external face of the following one, thus connecting the tongues into forming a virtually continuous wall, so that when the section is forced into a certain shape involving a curve or a series of curves, element (13) or elements (13") bend into the same shape which can be fixed and held once elements (13) or (13") are riveted or punched to the section's segmented walls. The invention to be used in building single or double curve false-ceilings, curved walls, interior finishing, domes, etc. |
