  • the bending stress generated in the outer plate 110 of the first reinforcing plate 100 is converted or reduced to the toroidal stress according to the cross-sectional shape of the outer plate 110 can increase the safety of the pressure vessel, in particular, the first
  • the height of the inner stiffener 120 is increased by the height of the peak portion 102, the leaflet edge phenomenon formed on the outer plate 110 of the flat plate form a uniform stress distribution in the wrinkled form of the first inner stiffener 120 Since there is an effect of increasing the effective plate width can increase the rigidity of the first inner reinforcement (120), due to this characteristic by increasing the spacing of the reinforcement than the conventional flat plate reinforcement plate by reducing the number of reinforcement And material costs There is an advantage that can be subtracted.
  • the bottom surface (V4) of the pressure vessel is configured by using the second reinforcing plate 200 having a flat cross-sectional structure, the liquid cargo can be smoothly flows to the specific portion of the bottom surface (V4) Therefore, the cargo handling operation can be carried out more smoothly, and there is an advantage of increasing the convenience of manufacturing and maintaining the pressure vessel.
  • connection reinforcement member 250 is used while maintaining the continuity of the structure at the connection portion of the first reinforcement plate 100 and the second reinforcement plate 200.

Abstract

La présente invention concerne un contenant sous pression de stockage de marchandises liquides, et a pour objet de fournir un contenant sous pression de stockage de marchandises liquides. Selon l'invention, en constituant un contenant sous pression au moyen d'une plaque de renfort ayant une structure de section transversale ondulée possédant des creux et des crêtes, une partie de la surface du contenant sous pression est constituée comme plaque de renfort ayant une section transversale plate de sorte que les marchandises liquides peuvent s'écouler régulièrement à l'intérieur du contenant sous pression, tout en améliorant le côté pratique de fabrication. À cette fin, le contenant sous pression de stockage de marchandises liquides selon la présente invention comprend : une pluralité de premières plaques de renfort qui ont une structure de section transversale ondulée possédant des creux et des crêtes et qui sont couplées les unes aux autres de façon à constituer une partie du contenant sous pression dans laquelle les marchandises liquides sont stockées ; et une ou plusieurs secondes plaques de renfort qui sont couplées aux premières plaques de renfort, qui constituent la partie restante du contenant sous pression et qui ont une structure de section transversale plate.
