An inflatable floating bridge which can be rolled up or folded up when it is not inflated. The bridge comprises two spaced-apart inflatable air hoses at the sides of the bridge, the inflation of these air hoses by means of pressurized air resulting in the laying out of the bridge. When said hoses have been inflated, and the bridge thus has been rolled out, they constitute the buoyant longitudinal side supporting means of the bridge. Between said hoses there is provided a sheet constituting the bridgeway and having its longitudinal sides fluid-tight joined to one of each hose. On the sheet there are also provided load distributing means and spacing means for the distribution of load and for the spacing-apart of the hoses. |
