Spacer are made from metal or plastic material, with mesh or openings, filled with filling mass (9), and it is longitudinal in direction of its longitudinal axis (5) with a given length and a given cross-section, perpendicular in section to the longitudinal axis (5) of spacer. Metallic or plastic material (3, 3a, 3b), allowing permanent deformation, with mesh openings, is wound around the longitudinal axis (5) into a spiral (2, 2a, 2b, 2c, 2d, 2e) with at least one thread ends (4), whereby beginning of thread (4) is mainly located either directly in the longitudinal axis (5), or parallel to it, and it is equipped with a ridge (11) in the opposite direction, as further driven thread (4), and the end of the thread (4) or the last thread (4) of the spiral (2, 2a, 2b, 2c, 2d, 2e) is situated mainly on the outer casing or creates partially or completely outside casing of spacer (1, 1b, 1c, 1d) from this material (3, 3a, 3b). This spiral (2, 2a, 2b, 2c, 2d, 2e) is filled outside and inside with filling materials (9) having the ability to transfer the filling materials (9) between its threads (4) and mesh or openings of this material (3, 3a, 3b). |
