Abstract

A module suitable for use in a crash barrier has a diaphragm with opposite first and second sides. First and second cellular foam blocks are coupled to the first and second sides of the diaphragm respectively. A wrap layer surrounds a periphery of the first and second cellular foam blocks. A sealant layer may be applied to the wrap layer. The wrap layer is configured as a metal cover member. A crash barrier may be configured with one or more modules. A method of manufacturing a module includes adhering first and second cellular foam blocks to opposite sides of a diaphragm and wrapping a wrap layer around a periphery of the first and second cellular foam blocks. A transition rail may be connected between first and second crash barriers.

First claim

What is claimed is:

1. A crash barrier comprising:
adapted to be supported by a base, said module comprising:
a diaphragm having opposite first and second sides;
first and second cellular foam blocks coupled to said first and second sides of said diaphragm respectively; wherein said diaphragm comprises a mounting portion extending downwardly from a bottom surface of said first and second cellular foam blocks' wherein said mounting portion is adapted to be coupled to said base and
a wrap layer surrounding a periphery of said first and second cellular foam blocks.

2. The crash barrier of claim 1 further comprising a sealant layer applied to said wrap layer.

3. The crash barrier of claim 2 wherein said sealant layer comprises a joint compound.

4. The crash barrier of claim 2 further comprising a coating applied over said sealant layer.

5. The crash barrier of claim 4 wherein said coating comprises a urethane primer.

6. The crash barrier of claim 1 wherein said mounting portion comprises a guide member, and further comprising said base, wherein said base comprises a support surface supporting a bottom of said module and a longitudinal track formed in said base, wherein said guide member is received in said track.

7. The crash barrier of claim 6 wherein said track comprises a cavity and a slot opening upwardly from said cavity, and said guide member comprises a leg portion extending through said slot and a foot portion received in said cavity, wherein said foot portion is shaped so as to not be removable through said slot.

8. The crash barrier of claim 6 comprising a plurality of said modules supported by said base and positioned end to end.

9. The crash barrier of claim 1 wherein said wrap layer comprises a permeable material.

10. The crash barrier of claim 9 wherein said wrap layer comprises a plurality of apertures, and wherein said sealant layer permeates said plurality of apertures and adheres to said first and second cellular foam blocks.

11. The crash barrier of claim 7 wherein said wrap layer comprises a fiberglass mesh.

12. The crash barrier of claim 1 wherein said diaphragm comprises a plurality of apertures, and further comprising an adhesive permeating said plurality of apertures and adhering to said first and second cellular foam blocks.

13. The crash barrier of claim 12 wherein said diaphragm comprises an expanded metal sheet.

14. The crash barrier of claim 13 wherein said adhesive comprises a gypsum cement product.

15. The crash barrier of claim 1 wherein said first and second cellular foam blocks define front and rear ends and opposite sides of said module, and wherein said wrap layer covers a top, said front and rear ends and said opposite sides of said module.

16. The crash barrier of claim 15 wherein said wrap layer comprises a cover member made of metal.

17. The crash barrier of claim 16 wherein said cover member is made of aluminum.

18. The crash barrier of claim 15 comprising a plurality of said modules positioned end to end, and further comprising a connector covering a junction between adjacent modules, wherein said connector is connected to said adjacent modules.

19. The crash barrier of claim 15 wherein said cover member comprises a side cover covering one of said front and rear ends and said opposite sides of said module, and a top cover covering said top and the other of said front and rear ends.

20. The crash barrier of claim 19 wherein said top cover comprises a flange extending from a periphery thereof and overlapping portions of said side cover.

21. The crash barrier of claim 15 further comprising a bottom bracket extending underneath said modules and having a pair of flanges connected to said opposite sides of said module.
