Claims (11)

1. The assembly of protective rails is used, in particular, as a system of keeping vehicles on the road, characterized by the fact that at least one chain of protective rails (2), consisting of protective rails connected together in a series, is located at a vertical distance (29) from the surface ( 6) the subsoil (7) and is attached to the columns (5), whereby the columns (5) are formed in the vertical direction (V) in two parts consisting of an anchor column (9) embedded in the subsoil (7) and a retaining column (8) and the flange (12) are placed on the upper end of the anchor post (9) and this flange (13) is placed on the retaining post (8) at the lower end, with both flanges (12, 13) resting in a plane against each other towards the other and are connected to each other and the connection takes place using screws (15), characterized by the fact that the flange (12) of the anchor post (9) has internal threads (32), and the screws (15) are screwed into the internal threads ( 32) so that they are included via the flange (13) of the retaining post (8), whereby the shear effect of the screws (15) is supported in the event of a side impact of a motor vehicle. 2. Assembly of protective rails according to claim 1, characterized in that the anchor post (9) is formed from a double T profile, especially an IPB or IPE profile. 3. Assembly of protective rails according to any one of claims 1 or 2, characterized in that the elongated holes (16) are located on the flange (13) of the retaining post (8) and/or the flange (12) of the anchor post (9), whereby elongated holes (16) extend oriented especially transversely to the pavement (30). 4. Assembly of protective rails according to any one of claims 1 to 3, characterized in that the anchor post (9) has a vertical length (10) greater than 800 mm. 5. Assembly of protective rails according to any one of claims 1 to 4, characterized in that the dividing plane (14) between the two flanges (12, 13) extends obliquely parallel to the surface (6) of the subsoil (7), in particular, to the surface roadway. 6. Assembly of protective rails according to any one of claims 1 to 5, characterized in that the screw bolts (15) extend oriented on their longitudinal axis at right angles to the dividing plane (14). 7. Guardrail assembly according to any one of claims 1 to 6, characterized in that the retaining post (8) on the rear side (22) has a support bracket (23) extending at an angle, with which the support bracket is supported on the flange (13 ). 8. Assembly of protective rails according to any one of claims 1 to 7, characterized in that the central longitudinal axis (21) of the retaining post (8) has a slope (25) towards the central longitudinal axis (20) of the anchor post (9) and/or that retaining post (8) connected to the slope (25) on the flange (13) of the retaining post (8). 9. Assembly of protective rails according to any one of claims 1 to 8, characterized in that the retaining post (8) is connected to the slope (25) in the direction towards the road on the anchor post (9). 10. Guard rail assembly according to any one of claims 1 to 9, characterized in that the flange (12) of the anchor post (9) has a greater wall thickness (W12) compared to the flange (13) of the retaining post (8) and/or wall thickness (W26) double T profile. 11. Assembly of protective rails according to any one of claims 1 to 10, characterized in that the anchor post (9) protrudes with a height (11) between 0 and 100 mm, preferably between 0 and 50 mm, especially preferably between 1 and 40 mm in relation to the surface (6) or the road surface (31).
