摘要

The device (1) has a support element (2) that is provided with a hollow portion (4) at one end of the full hollow elements (7) in the longitudinal axis (3). The support elements are essentially introduced horizontally along the longitudinal, and are adapted to be supported in parallel to a slope. Several support elements are connected to each other in parallel to the longitudinal axis to form a stack. A mounting element (6) is provided with the support element. An independent claim is included for method for manufacturing backup and fastening device.
