CLAIMS

1. A device for filling or creating a void within a construction medium, the device comprising :

a body having at least one inflatable body portion, each inflatable body portion having one or more inflatable cavity,

at least one valve member fluidly connected to the one or more inflatable cavity to control flow of fluid into and inflate said cavity, wherein, in-use, the one or more cavity are shaped to substantially fill or create the void in a construction medium when in an inflated state.

2. The device as claimed in claim 1, wherein the shape of the device or at least the shape of one or more inflatable cavity of the device, when in an inflated state, corresponds to the shape of the void to be filled or created.

3. The device as claimed in claim 1 or 2, wherein the body comprises at least one cover portion substantially devoid of one or more inflatable cavity.

4. The device as claimed in claim 3, wherein in an operative state, said device is coupled about an object to protect said object, wherein said at least one inflatable body portion forms an inner layer adjacent the object and said at least one cover portion forms an outer layer substantially adjacent an exterior-facing surface or surface portions of the inner layer.

5. The device as claimed in claim 4, wherein the inner layer is of a perimeter and length which substantially envelops an outer periphery of said object, and the outer layer is of a perimeter and length that substantially envelops the inner layer.

6. The device as claimed in any one of claims 3-5, wherein the body comprises at least one flap portion substantially devoid of the one or more inflatable cavity, extending from the cover portion and configured to extend, in-use, over an end of the inflatable body portion in the operative state.

7. The device as claimed in any one of claims 3-5, wherein a flap portion extends from one or both ends of the inflatable body portion.

8. The device as claimed in any one of claims 1-7, wherein two or more valve members are associated with two or more fluidly connected separate inflatable cavities.

9. The device as claimed in any one of claims 1-8, wherein the valve is configured to receive fluid from a fluid source to introduce into said one or more inflatable cavity.

10. The device as claimed in claim 9, wherein the fluid is a fire retardant substance.

11. The device as claimed in any one of claims 1-10, wherein the one or more inflatable cavities comprise a pre-stored foaming agent, and an activation mechanism for activating the foaming agent to inflate said cavity.

12. The device as claimed in any one of claims 3-7, wherein the at least one cover portion is substantially smooth to provide a substantially smooth outer layer adjacent the surrounding or construction medium in use.

13. The device as claimed in any one of claims 1-12, wherein the at least one inflatable body portion comprises a cavity having a plurality of longitudinally extending inflatable cavity sections across the inflatable body portion.

14. The device as claimed in claim 13, wherein each cavity section is fluidly coupled to adjacent cavity section(s) at corresponding ends of the sections.

15. The device as claimed in claim 13 or 14, wherein in an operative state, the cavity sections are longitudinally aligned with a longitudinal axis of the conduit and circumferentially spaced about the periphery of the conduit.

16. The device as claimed in any one of claims 13-15, wherein the sections are all of a substantially similar size or volume.

17. The device as claimed in any one of claims 13-15, wherein the sections are of alternating larger and smaller sizes or volumes.

18. The device as claimed in any one of claims 1-17, wherein the at least one inflatable body portion comprises a plurality of inflatable cavity sections configured in fluidly distinct groups of one or more inflatable cavity sections.

19. The device as claimed in any one of claims 1-18, wherein the at least one inflatable body portion comprises a plurality of longitudinally extending and substantially parallel cavities.

20. The device as claimed in any one of claims 1-19, wherein one or more of the inflatable cavity comprises an internal web structure (such as for providing shape and/or strength to the cavity).

21. The device as claimed in any one of claims 3-20, wherein the cover portion extends integrally from one side of the inflatable body portion.

22. The device as claimed in any one of claims 3-20, wherein the cover portion extends integrally from opposing sides of the inflatable body portion.

23. The device as claimed in any one of claims 1-22, wherein the at least one inflatable body portion, or the at least one cover portion substantially devoid of one or more inflatable cavities, or both, comprises one or more cut-outs.

24. The device as claimed in claim 23, wherein the one or more cut-outs are interspersed between the one or more inflatable cavities,

25. The device as claimed in claim 24, wherein cut-outs of the at least one cover portion are arranged to correspond with one or more cut-outs in the at least one inflatable body portion.

26. The device as claimed in any one of claims 23-25, wherein the cut-outs are a slit or slot or section of material removed or are a region defined by a frangible perimeter, such that, in-use, the cut-outs facilitate a construction medium to pass therethrough.
