Definitions

  • This invention relates to a method for isolating the tank walls from a ship whereby said walls are to be coated with a thermally-isolating plastic foam.
  • the invention has not only for object to obviate the above drawbacks but also to provide an original solution to the following problems :
  • isolating panels from said plastic material which are finished on the outer side thereof with a metal sheet and are provided with openings which are pushed over pins soldered to the tank wall, whereby on said pins are screwed elements which press said panels against the tank wall, and in the space between said panels is injected a hardenable isolating foam after having laid an adhesive tape on those edges lying next to one another of said panels, to form said space.
  • a feature of the method according to the invention lies in arranging inside said space between said isolating panels, against the tank wall to be isolated, a resilient strip from foam material which retains the pressure from the foam material to be injected and prevents the further flowing thereof.
  • the hardenable plastic material is injected in the space present between the isolating panels through said adhesive tape.
  • the invention also relates to the isolating panels and fasteners used with the above-defined method.
  • the method illustrated by the figures pertains to the isolating of the bottom wall 1 from a tank 2. It is clear that the vertical walls of a tank may be treated in the same way.
  • top side or roof of a tank can be finished in a similar way or according to a more conventional method, depending on the particular conditions.
  • a number of pins 3 are soldered to wall 1.
  • Said pins which are regularly spaced, are made from stainless steel and the head 3' thereof is provided with a screw thread.
  • An isolating panel 4 Over each set from four pins 3 is pushed an isolating panel 4.
  • the isolating panels 4 (fig. 2) are comprised of an isolating self-extinguishing foam layer 5 and are finished on the outer side with an aluminum sheet 6. Said isolating panels thus have a number of openings 7 which are distributed over the panel surface area according to a module which corresponds to the module according to which said pins 3 are distributed over the tank wall.
  • conical components 8 are pushed over pins 3 in said openings 7. Said conical components 8 are retained pressed against tank wall 1 by screwing self-locking nuts 3" on the heads 3' of pins 3.
  • said conical components 8 have a collar 9 which is retained pressed against resilient sealing rings 10.
  • the space above head 3' from pins 3 is sealed with a plug 11 and a cover 12.
  • Said components 8 provided with an inner centering ring 8' are made from a synthetic or plastic material, preferably polyethylene.
  • a strip 14 from foam material On the wall of an isolating panel is arranged, preferably by nailing, a strip 14 from foam material. Said strip connects tightly to said tank wall, is slightly compressed under the action of injected foam 13 and prevents any further flowing out of said foam between the tank wall and panel.
  • the expansion of the hardenable foam can occur in those spaces determined by said adhesive tapes and be tested with the hand from the outside. An excess of foaming material will be received by the resilient strips from foam material, as an open-cell material is preferred therefor. Due to the presence of said foam strips, entering of foam between the tank wall and.the panels to be isolated is also prevented, which would otherwise bring the danger of the panels being pushed away from the walls.
