Abstract

The invention shows a projectile arresting module (1) comprising a base frame (3), partition walls (9), stopping material (11) positioned between the partition walls (9) and a pressure resisting wall (19). The pressure resisting wall (19) comprises a tight row (25, 27) of vertical hollow sections (15). The inventions also shows a projectile arresting arrangement (100, 200, 300) comprising at least two projectile arresting modules (1), which at least two projectile arresting modules (1) are grouped together, thereby forming an I-shape, L-shape, U-shape, C-shape, F-shape, T-shape or E-shape.

Claims

1. A projectile arresting module comprising:

a base frame forming a floor and a back wall of the projectile arresting module,

partition walls extending in a direction substantially perpendicular to the back wall, the partition walls comprising a back edge attached to the base frame, and a front edge,

stopping material positioned between the partition walls, and

a pressure resisting wall comprising

horizontal support elements attached to the front edge of the partition walls, and

a tight row of vertical hollow sections connected to the horizontal support elements.

2. The projectile arresting module according to claim 1, wherein the vertical hollow sections are attached to hollow plastic profiles surrounding the horizontal support elements.

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

4. The projectile arresting module according to claim 1, wherein the vertical hollow sections comprise a plastic material.

5. The projectile arresting module according to claim 1, wherein the vertical hollow sections have a cross section length of 30-50 mm and a cross section width of 100-200 mm.

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

7. The projectile arresting module according to claim 6, wherein the roof is attached to the base frame and the partition walls.

8. The projectile arresting module according to claim 7, wherein the roof comprises a roof bottom layer made of a row of hollow sections, and a roof top layer.

9. The projectile arresting module according to claim 8, wherein the roof top layer comprises a ballistic steel plate.

10. The projectile arresting module according to claim 8, further comprising a space between the roof bottom layer and the roof top layer.

11. The projectile arresting module according to claim 10, wherein the space has a height of 50-300 mm.

12. The projectile arresting module according to claim 1, wherein the base frame is a standard ground support element.

13. A projectile arresting arrangement comprising at least two projectile arresting modules in accordance with claim 1, which at least two projectile arresting modules 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 module according to claim 4, wherein the plastic material comprises a reinforced plastic material.

15. The projectile arresting module according to claim 1, wherein the vertical hollow sections have a cross section length of 35-45 mm and a cross section width of 115-125.

16. The projectile arresting module according to claim 10, wherein the space has a height of 100 mm.

17. The projectile arresting module according to claim 1, wherein the base frame is a standard ground support element comprising a precast concrete retaining wall unit.
