Крепежный элемент для применения в горнодобывающей промышленности и тоннелестроении, содержащий основную часть (12; 32; 42; 52), которая на своей внешней стороне (13; 33; 43; 53) снабжена множеством ослабленных участков (14, 15; 34, 35; 44, 45; 54) поперечного сечения в качестве мест запрограммированного разрушения, отличающийся тем, что ослабленные участки (14, 15; 34, 35; 44, 45; 54) сформированы в виде спирали и пролегают вдоль длины основной части (12; 32; 42; 52). ! 2. Крепежный элемент по п.1, отличающийся тем, что по меньшей мере два ослабленных участка (34, 35; 44, 45) имеют различные направления вращения. ! 3. Крепежный элемент по п.1, отличающийся тем, что по меньшей мере два ослабленных участка (14, 15) имеют различный наклон. ! 4. Крепежный элемент по п.1, отличающийся тем, что основная часть (32; 42; 52) является трубчатой. ! 5. Крепежный элемент по п.1, отличающийся тем, что по меньшей мере один из ослабленных участков (34, 35; 44, 45) на внешней стороне (33; 43) основной части (32; 42) является выемкой. ! 6. Крепежный элемент по п.5, отличающийся тем, что выемка, идущая от внешней стороны (33) основной части (32), имеет глубину (Т), которая соответствует величине 0,01-0,3 от внешнего диаметра (D) основной части (32). ! 7. Крепежный элемент по п.1, отличающийся тем, что множественные равнонаправленные ослабленные участки (34, 35; 44, 45) предусмотрены значительно смещенными друг к другу на внешней стороне (33; 43) основной части (32; 42). ! 8. Крепежный элемент по п.1, отличающийся тем, что ослабленные участки (34, 35) поперечного сечения образованы посредством частичной термической обработки основной части (32). ! 9. Крепежный элемент по одному из пп.1-8, отличающийся тем, что ослабленные участки (44, 45; 54) поперечного се� 1. A fastener for use in mining and tunneling, containing the main part (12; 32; 42; 52), which on its outer side (13; 33; 43; 53) is equipped with many weakened sections (14, 15; 34, 35; 44, 45; 54) of the cross section as the places of programmed destruction, characterized in that the weakened sections (14, 15; 34, 35; 44, 45; 54) are formed in the form of a spiral and lie along the length of the main part (12; 32; 42; 52). ! 2. The fastener according to claim 1, characterized in that at least two weakened sections (34, 35; 44, 45) have different directions of rotation. ! 3. The fastener according to claim 1, characterized in that at least two weakened sections (14, 15) have a different slope. ! 4. The fastener according to claim 1, characterized in that the main part (32; 42; 52) is tubular. ! 5. The fastener according to claim 1, characterized in that at least one of the weakened sections (34, 35; 44, 45) on the outside (33; 43) of the main part (32; 42) is a recess. ! 6. A fastener according to claim 5, characterized in that the recess extending from the outside (33) of the main part (32) has a depth (T) that corresponds to a value of 0.01-0.3 from the outer diameter (D) the main part (32). ! 7. The fastener according to claim 1, characterized in that the multiple equally directed weakened sections (34, 35; 44, 45) are provided significantly offset to each other on the outside (33; 43) of the main part (32; 42). ! 8. The fastener according to claim 1, characterized in that the weakened sections (34, 35) of the cross section are formed by partial heat treatment of the main part (32). ! 9. A fastener according to one of claims 1 to 8, characterized in that the weakened sections (44, 45; 54) of the transverse section
