  • This embodiment ensures a connection by obstacle and guarantees a perfect seal against water (rain, runoff).
  • the connection between the roof 4 and the side wall 2 can be completed by providing a flange 13 extending the internal skin 9 and which is welded and / or bonded thereto.
  • the side wall 2 is placed on the floor 3 and is connected to the latter by a flange 14 extending the external skin 8, part of which is applied to the edge of the floor 3, while the other part 16 is glued and welded to the external face of said floor 3.
  • This embodiment guarantees a water tightness.
  • the connection of the floor 3 and the side wall 2 can be completed by a flange 17 extending the internal skin 9 of the side wall 2 applied against the internal face of the floor on which the flange 17 is welded and / or glued.
  • the panel constituting the side wall 2 and the roof 4 is shown in cross section in FIG. 2.
  • This panel consists of an aluminum core 20 of honeycomb, an outer skin 21 and a skin internal 22, each skin being bonded with a film of glue 23 to the core 20.
  • the skins 21 and 22, as indicated above, are aluminum sheets approximately 0.8 mm thick, of which the temperature resistance is of the order of 110 ° C. continuously.
