  • ABSTRACT Forelgn Apphcanon Pnomy Data A construction for a liquid-tight joint between adja- July 9, 1971 Japan 46/50831 cent edges of panels forming the inner wall of a low July 9, 1971 Japan 46/50832 temperature torage tank each being of multilayer construction and having a liquid-tight membrane --52/753 J, 52/463, 220/9 LG, as an interior layer.
  • a patch member covers the adja- 220/9 T, 2 0/9 F, 2 cent edge portions of a pair of panels at the joint and [51 1 Int- Cl.
  • the present invention relates to a junction construction for low temperature purpose liquid-tight panels used to form a liquid-tight inner wall for low temperature liquified gas storage tanks.
  • plywood has a low coefficient of expansion or contraction in connection with temperature change, it is used as a wall material for low temperature liquified gas storage tanks.
  • plywood is lacking in liquid-tightness, it is necessary to make it liquid-tight when it is used as an inner wall material for such a tank.
  • Plywood constructions made liquid-tight have heretofore been known, including those having a low temperature resistant metal sheet, such as of aluminum or stainless steel, bonded to the surface of the plywood, and those having a low temperature resistant synthetic resin film bonded to the surface of the plywood.
  • the metal sheet or synthetic resin film is intended for providing liquidtightness, not for supporting liquid pressure, the thickness thereof may be of the order of 0.3-0.1mm.
  • liquidtight multi-ply panel In order to'eliminate these drawbacks due to thermal factors and mechanical damage, an improved liquidtight multi-ply panel has been devised.
  • One or more metal sheets or synthetic resin films serving as liquidtight membranes are arranged at suitable intervals within a panel consisting of a plurality of wood veneers, or such a liquid-tight membrane is bonded to the surface of a plywood panel and is then topped with a soft fibrous material bonded thereto.
  • liquid-tight panels of such construction When liquid-tight panels of such construction are used to constitute the inner tank wall, it is necessary to maintain liquid-tightness between the adjacent edges thereof.
  • the mere bonding of a seal sheet between the adjacent abutting edges would not provide sufficient liquid-tightness because the low temperature liquid side of the panels is formed of a veneer or fibrous layer, permitting the liquid to permeate the layer and leak to the outside from between the adjacent edges.
  • the object of the present invention is to completely prevent the leakage of liquid through a joint between low temperature purpose liquid-tight panels having no liquid-tight membrane exposed on the surfaces thereof.
  • the present invention provides a junction construction for use at a joint between the edges of a pair of multi-ply panels supported on joists to form a portion of the inner wall of a low temperature liquid storage tank, each panel having an interior ply formed by a low temperature resistant liquid-tight membrane; wherein, a patch member covers the joint and is secured by suitable fastening means to each of the panels and to a joist, a relieved portion is formed on the inner wall surface of each of the panels exposing the surface of the membrane thereof adjacent the sides of the patch member, and a low temperature resistant adhesive covers the patch member and the exposed surfaces of the membranes of the panels.
  • the liquid-tight membranes of the panels are continuously interconnected at the junction by the low temperature resistant adhesive to constitute a perfect liquid-tight barrier, with the result that the danger of liquid leaking through the junction is eliminated. Moreover, the liquid-tight membranes are prevented from contacting low temperature liquid even at the junction, so that it is possible to completely eliminate the drawbacks due to thermal factors and mechanical damage.
  • FIG. 1 is a perspective view in transverse section through the wall of a tank showing ajunction construction of the invention employing one type of multi-ply liquid-tight panel;
  • FIG. 2 is a transverse section of an embodiment of the invention using another type of liquid-tight panel.
  • FIGS. 3 and 4 are perspective sectional views showing other types of liquid-tight panels.
  • Multi-ply liquid-tight panels 1 shown in FIG. 1 are each constructed by bonding liquid-tight membranes 4a and 4b of low temperature resistant metal to both sides of a plywood unit 3 consisting of a plurality of veneers 2, and then bonding veneers 5a and 5b to the surfaces of said liquid-tight membranes 4a and 4b to serve as heat shock absorbing members.
  • the veneer 5a of the panel 1 which will be in direct contact with low temperature liquid is cut away in advance over a predetermined width from the edge thereof to form a relieved portion exposing a band 6 of the surface of the membrane 4a.
  • Connector joists 8 are disposed in a latticelike pattern within an ordinary steel plate outer wall 7 of a low temperature liquified gas storage tank so as to be in conformity with the size of the liquid-tight panels 1 and the joists 8 are secured to the outer wall through stay plates 9.
  • the adjacent edge portions of such liquid-tight panels 1 are placed on one of the joists 8, and a connector patch member 12 is bonded to the outer side of said adjacent edge portions 10 over the bandlike exposed membrane surfaces 6 by means of an adhesive 11.
  • the width of the patch member 12 is such that some areas of the band-like exposed membrane portions 6 are left uncovered on both sides of the patch member 12.
  • Fastening means 13, such as nails, are driven through the patch member 12 into the joist 8 through both panels 1, thereby securing the adjacent edge portions 10 to the joist 8. Finally, a coating layer 14 of low temperature resistant adhesive is applied over the patch member 12 and the band-like exposed membrane surfaces 6 left uncovered on both sides of the patch member.
  • the numeral 15 designates a heat insulator, which is prepared either by injecting a foamable material into a space surrounded with a lattice-like enclosure defined by the connector joists 8 and stay plates 9, the outer wall 7 and the low temperature resistant liquid-tight panels 1 through openings in said latticelike enclosure, and allowing the material to foam in said space; or, by filling the lattice-like enclosure with a preformed heat insulator before the low temperature resistant panel 1 is secured in position.
  • liquid-tight panel 1 shown in the above embodiment it is, of course, possible to prevent the separation and cracking of the membranes by absorbing the heat shock caused by direct contact between the inner wall of the tank and the low temperature liquid, and since the membranes 4a and 4b are symmetrically arranged with respect to the center of the panel and expand and contract approximately equally, such expansion and contraction of the membranes 4a and 4b will not result in warping the panel 1.
  • the entire liquid-tight panel can ideally expand and contract.
  • single ply veneers 5a and 5b are bonded to the surfaces of the liquid-tight membranes 4a and 4b, but a laminate formed by a plurality of veneers may be bonded thereto as a heat shock absorbing material.
  • a method may be employed wherein hot pressing is carried out with a resin-impregnated paper sheet interposed between the membrane and a veneer on each side thereof.
  • FIG. 2 shows a different embodiment of the invention.
  • a liquid-tight panel used in this embodiment consists of two plywood layers 21a and 21b of approximately the same thickness with a liquid-tight membrane 22 of low temperature resistant metal interposed therebetween. If such a panel 20 were applied to the embodiment shown in FIG. 1, since the thickness of the plywood 21a working as a heat shock absorbing material with respect to the liquid-tight membrane amounts to about half the thickness of the panel 20, a bandwise cutting away of the plywood 21a for placing a connector patch member on the cut away area would result in the adjacent edge portions of the panels being too thin, thus presenting a problem of strength. Therefore, as shown in FIG.
  • a connector patch member 23 is bonded directly to the surfaces of adjacent panels 20 by an adhesive, and the adjacent edge portions 25 of the panels 20 are secured to a connector joist 26 by fasteners 24.
  • grooves 27 reaching the liquid-tight membranes 22 are provided in the plywood 21a parallel to the patch member 23.
  • Each groove 27 is filled with a low temperature resistant adhesive 28 so as to be in contact with the liquid-tight membrane 22, and a coating layer 29 of low temperature resistant adhesive covering the patch member 23 is united with said low temperature resistant adhesive 28, thereby interconnecting the panels 20 in a liquid-tight manner without involving any problem of strength.
  • FIGS. 3 and 4 show other embodiments of liquidtight panels useable in the present invention.
  • a liquid-tight panel 30 is constructed by bonding liquidtight membranes 33a and 33b of low temperature resistant metal or synthetic resin to both sides of plywood 32 consisting of a plurality of layers of veneers 31 and then bonding a soft fibrous material 34 of suitable thickness serving as a heat shock absorbing material to the outer side of one membrane 33a.
  • the fibrous material may be a wood fiber plate, a thick fabric, a laminated thin fabric, a rug or the like.
  • the low temperature liquid permeates the fibrous material 34 when the fibrous material 34 forms the inner side of the tank, permeation beyond the same is prevented by the liquid-tight membrane 33a. Therefore, heat shock caused by direct contact between the liquid-tight membrane 33a and the low temperature liquid can be avoided by the fibrous material 34, so that there is no possibility of the membrane 33a coming off or cracking. Further, since the liquid-tight membranes 33a and 33b are positioned on both sides of the plywood 32 and expand and contract approximately equally, there will be no possibility that the plywood will warp as a result of the expansion and contraction of the membranes 33a and 33b.
  • a liquid-tight panel 40 shown in FIG. 4 is constructed by interposing two or more layers of low temperature resistant resin-impregnated paper sheets 43 between plywood veneers 41 and 42 and subjecting the assembly to a hot press process.
  • the thermal stresses produced in the liquid-tight membranes are very small as compared with the case of using a low temperature resistant metal sheet, so that the plywood will not warp.
  • the low temperature resistant resin-impregnated paper sheets 43 are easy to bring into close contact with the plywood veneers, so that the production of the liquid-tight panel is facilitated.
  • junction construction for use at a joint between the edges of a pair of multi-layer panels supported on joists to form a portion of the inner wall of a low temperature liquid storage tank, each panel having an interior layer formed by a low temperature resistant liquid-tight membrane, said junction construction comprising:
  • relieved portion comprises a band of exposed membrane surface extending inwardly from the adjacent edges of each of the panels, each band being partially covered by the patch member and the remainder of the exposed membrane surface of each band being covered by the low temperature resistant adhesive.
