Abstract

The present invention concerns a security barrier for providing protection in a public space or the like, said barrier comprising a mineral wool assembly comprising at least one mineral wool element having an outer liquid impermeable covering and wherein the at least one mineral wool element is adapted for being filled with a liquid. The invention further comprises a method of manufacturing such security barrier and a method of preparing the security barrier for providing protection in a public space.

First claim

The invention claimed is:

1. A security barrier for providing protection in a public space or the like, said barrier comprising a mineral wool assembly comprising at least one mineral wool element having an outer liquid impermeable covering comprising a coating selected from a group consisting of polystyrene foam, including expanded polystyrene and extruded polystyrene foam, styrofoam, and polyurethane foam, and wherein the at least one mineral wool element is adapted for being filled with a liquid.

2. A security barrier according to claim 1 , wherein the security barrier is filled with a liquid, said liquid comprising water.

3. A security barrier according to claim 1 , wherein the density of the at least one mineral wool element in its dry state is 75-200 kg/m 3 .

4. A security barrier according to claim 1 , wherein a plurality of mineral wool elements are provided adjacent each other.

5. A security barrier according to claim 4 , wherein the mineral wool elements form a common base surface of the mineral wool assembly with two opposite end surfaces substantially perpendicular to the base surface, and wherein the top surfaces of the mineral wool elements are at different distances from the base surface.

6. A security barrier according to claim 1 , wherein the liquid impermeable covering is a covering foil and/or fibre laminate, such as glass fibre laminate or a carbon fibre laminate.

7. A security barrier according to claim 6 , wherein the outermost layer of the laminate is a covering foil.

8. A security barrier according to claim 6 , wherein the foil or laminate is adhered to the at least one mineral wool element by an adhesive, such as a liquid adhesive or a powder adhesive, which is insolvable by the liquid to be filled into the security barrier.

9. A security barrier according to claim 6 , wherein the laminate is adhered to the at least one mineral wool element by a resin of a fibre reinforced laminate.

10. A security barrier according to claim 1 , wherein the liquid impermeable covering is provided with a predetermined colour scheme, such as printings of logos or the like.

11. A security barrier according to claim 1 , wherein an opening for liquid filling is provided in the liquid impermeable covering, such as in the upper portion of the mineral wool assembly, for instance in the top surface thereof.

12. A security barrier according to claim 11 , wherein there is provided a liquid filling cover covering the opening.

13. A security barrier according to claim 1 , wherein a metal sheet cover is provided on one or more of the sides of the barrier.

14. A security barrier comprising:
a mineral wool assembly comprising at least one mineral wool element having an outer liquid impermeable covering, wherein the at least one mineral wool element is adapted for being filled with a liquid, wherein a moisture detection sensor is provided in the mineral wool assembly in an upper half thereof.

15. A security barrier according to claim 1 , wherein a drainage arrangement, such as a hole and a plug, is provided in the coating in the vicinity of the base surface.

16. A method of manufacturing a security barrier according to claim 1 , said method comprising the steps of:
providing a mineral wool assembly comprising at least one mineral wool element, and
mounting an outer liquid impermeable covering around the mineral wool assembly.

17. A method according to any claim 16 , whereby the step of mounting an outer liquid impermeable covering involves spray coating of the outer surface of the mineral wool assembly.

18. A method according to claim 16 , whereby a plurality of mineral wool elements are provided adjacent each other and adhered to each other to form the mineral wool assembly, and whereby the mineral wool elements are secured to each other in discrete spots prior to the coating.

19. A method of preparing a security barrier for providing protection in a public space, wherein the method comprises the steps of: positioning the security barrier manufactured by a method according to claim 16 , and then filling the security barrier with a liquid.
