Definitions

  • the invention concerns an insulation for liquid gas containers, especially spherical containers, consisting of individual insulating panels.
  • Liquified gas for example natural gas, methane or the like is being transported over long distances and stored in large quantities to an increasing degree.
  • the insulation of transport or storage containers for liquid gas involves considerable difficulties. In the case of cubic or cylindrical containers, costly and difficult designs are required for insulation, since the insulation must be rigid and possess great strength. It is difiicult to attach the insulation to the container, since the use of fastening elements welded to the container is usually not allowed and is impossible due to the different degrees of expansion of the different materials at low temperatures.
  • Foam plastics which have proven to be highly efficient as insulators, have large expansion coefficients (and in the cold, large contraction coefficients) that result in considerable joint formation and cold bridge formation, so that undesirable convection currents develop.
  • Types of insulation are already known that consist of particularly costly designs, e.g., laminated plywood panels with polyurethane foam and balsa wood, which are used especially for cubic containers.
  • An object of the present inveniton is to make an insulating material for containers used to transport and/or store very cold liquids, said insulation possessing a certain stiffness that prevents the formation of through cracks, with the resultant number of joints being exactly definable both as to position and dimensions, and also possessing technical advantages with respect to both insulation and assembly, especially a facilitation of assembly with regard to precision and freedom from flaws.
  • This purpose is accomplished according to the invention primarily by the fact that at least two layers of plastic panels are provided that have rabbeted edges and have fastening elements at their centers, said panels being mounted in two superposed layers.
  • the central fastening elements of the inner panels fit into the rabbeted edges of the outer panels and the panels in the inner layer are staggered with respect to each other and with respect to the panels of the outer layer.
  • the insulating panels have rabbeted edges such that molded shoulders are formed where two edges butt against each other. This ensures a very tight connection between abutting insulation panels and avoids through cracks in one layer.
  • known force-accepting elements can be molded into the centers of the panels, at approximately half the thickness of said panels, and connected to the fastening and holding elements.
  • Such known force-accepting elements require a relatively small panel area for fastening and allow distribution of force over a large area, so that relatively large forces can be withstood even when applied vertically to the panel plane, without the forceaccepting elements being torn out of the panels.
  • the relative movements of the inner layer that result from expansion due to heat and contraction due to cold can act on the fastening points on the centers of the elements.
  • panel elements in one layer are arranged in rows and each row is staggered by one-half the panel length with respect to the adjacent row.
  • a further advantageous embodiment of the invention consists in that the panel elements and rows of the outer layer are applied so as to be staggered with respect to the panel elements in the lower layer on all sides.
  • FIG. I Arrangement of insulating elements, top view.
  • FIG. 2 Cross section through the arrangement in FIG. 1.
  • FIG. 3 A detail of the connection between the two layers on an enlarged scale
  • FIG. 4 Schematic representation of an insulating panel element according to the invention.
  • the insulation consists of individual insulating panels 2 and 3 that are arranged in sequential rows and in adjacent rows, with adjacent rows being staggered approximately half a panel length with respect to each other. It is also evident that the insulation consists of two layers with the panels in the outer layer being staggered with respect to the plates in the inner layer with respect to both length and width and also staggered with respect to the adjacent rows of panels in the outer layer.
  • the panels in the inner layer have fastening means in their centers; the prongs 7 of said fastening means can be seen in FIG. 1, and fit into the rabbeted edges 11 of the outer panel 3.
  • FIGS. 2 and 3 the panels 2 of the inner layer are mounted above the container wall 1 in such a fashion that projection 8 on panel 2 is slid over shoulder 10 on a second panel 2, thus avoiding a through joint.
  • Plates 2 on the inner layer have forceaccepting elements 4 molded approximately in the center of the panel, said elements having hexagon-head screws 5 and fastening prongs 7 and lock washers 6 on said hexagon-head screws.
  • the panels of the outer layer are applied and placed with shoulders in the vicinity of the fastening means 5,6,7.
  • screw 5 is tightened prongs 7 are pressed into panel 3 and then an adjacent panel 3 is slid on so that the corresponding projection 8 comes to rest on shoulder 10 on the first panel. Since the fastening means for the panels in the two layers are completely contained inside the insulating layer, through cold or heat bridges are completely avoided.
  • the container wall 1 is a part of a relatively large sphere with a large radius so that the individual panels 2,3 can be viewed practically as flat panels.
  • the invention is not limited to the sample embodiments shown and described. It includes all advantageous and expert modifications as well as all partial and subcombinations of the described and/or shown features and measures.
  • Insulation for liquid gas containers comprising:
  • a plurality of molded inner foamed synthetic insulating panels each having rabbeted edges, each having a fastening element at the center thereof projecting upwardly from approximately halfway through the thickness thereof and each having a forceaccepting element embedded in the center of each panel during molding thereof at approximately half the thickness of said panel;
  • said inner insulating panels being adapted for arrangement on a gas container with each panel being staggered with respect to at least one of the next adjoining panels and interlocking therewith;
  • outer insulating panels being adapted for arrangement on said inner insulating panels with each outer panel being staggered with respect to at least one of the next adjoining outer panels and interlocking therewith and each said outer panel being staggered with respect to said inner panels;
  • said fastening element comprises a clamping screw and fastening prong which are linked to said force-accepting element.
  • a container for storing or transporting liquid gas said container having a spherical wall the outer surface of which lies against the inner surface of said inner panels.
  • said rabbeted edges of said inner and said outer panels comprise flange projections on two adjacent edges and flange-receiving shoulders for receiving and interlocking with flange projections on the other two adjacent edges of adjoining panels.
