Abstract

The present invention relates to a projectile arresting device (1) comprising a foundation (3) constituting a floor (7) and a rear wall (5) of the projectile arresting device. It further comprises partition walls (9) extending in a direction substantially perpendicular to the rear wall (5), wherein the partition walls comprises a rear edge (10a) connected to the foundation (3), and a front edge (10b). Stopping materials (11) is arranged between the partition walls (9). A stopping material retaining layer (S) is arranged between the partition walls, and a pressure resistant wall (19) comprising a number of closely situated hollow sections (15) are connected to the front edges (10b) of the partition walls. The pressure resistant wall (19) further comprises a rear surface connected to the stopping material retaining layer (S) and a front surface. The front edge (10b) of each partition wall comprises a V-shaped profile of ballistic material, wherein a tip (12a) of the profile is adjacent to the pressure resistant wall. The invention also relates to a projectile arresting arrangement.

Claims

1. A projectile arresting device comprising:

a foundation constituting a floor and a rear wall of the projectile arresting device,

partition walls extending in a direction substantially perpendicular to the rear wall, the partition walls comprising a rear edge, arranged to the foundation, and a front edge,

stopping material arranged between the partition walls,

a stopping material retaining layer (S) disposed between the partition walls, and

a pressure resistant wall comprising a number of closely situated hollow sections connected to the front edges of the partition walls, the pressure resistant wall further comprising a rear surface coupled to the stopping material retaining layer (S) and a front surface, the front edge of the partition walls comprising a V-shaped profile of ballistic material, wherein a tip of the profile is adjacent to the pressure resistant wall.

2. The projectile arresting device according to claim 1, wherein the tip of the profile further comprises a wing.

3. The projectile arresting device according to claim 2, wherein at least one profile of polymeric material is provided to the wing of the profile and further is connected to the pressure resistant wall.

4. The projectile arresting device according to claim 1, wherein the hollow sections are provided with a groove and a tongue to connect the hollow sections to each other.

5. The projectile arresting device according to claim 1, wherein the hollow sections are made of a polymeric material or a reinforced polymeric material.

6. The projectile arresting device according to claim 1, wherein the projectile arresting device comprises a roof projecting from the rear wall and covers an area in front of the projectile arresting device.

7. The projectile arresting device according to claim 6, wherein the roof is connected to the foundation and the partition walls.

8. The projectile arresting device according to claim 6, wherein the roof comprises a manhole (M).

9. The projectile arresting device according to claim 1, wherein a moisture barrier layer is arranged between the foundation and the stopping material.

10. The projectile arresting device according to claim 9, further comprising at least one drainage pipe disposed in connection with the moisture barrier layer.

11. The projectile arresting device according to claim 1, wherein a surface layer is arranged in front of the front surface of the pressure resistant wall for target projections.

12. The projectile arresting device according to claim 1, wherein the projectile arresting device comprises a movable modular unit comprising a foundation constituting a floor, a rear wall and a roof.

13. A projectile arresting arrangement comprising at least two projectile arresting devices according to claim 12, wherein at least two projectile arresting devices are grouped together, thereby forming an I-shape, L-shape, U-shape, C-shape, F-shape, T-shape or E-shape.

14. The projectile arresting device according to claim 7, wherein the roof comprises a manhole (M).
