Definitions

  • the present invention relates to improvements in ship cover or deck structures.
  • a reinforcing angle material, a bulk plate, a flat bar, and the like are fixed at predetermined intervals to the back surface of the top plate in addition to the main bone by welding.
  • the top plate of the hatch cover bends due to seawater being poured from above or the load of the loaded container, so that each area surrounded by the reinforcement is parallel to the front, back, left and right sides. Is compressed, which can cause the top plate surrounded by the main bone to partially buckle.
  • the same is true for car decks and the like of heavy vessels such as loaded vehicles.
  • the interval (pitch) between these reinforcing members must be as small as possible, which results in a very large number of welding steps and a reduction in productivity. was there.
  • fillet welding is performed on the top plate 10 on both sides of the butt end of the angle material 11, and particularly the pitch
  • the top plate 10 was large and easily bent due to welding distortion.
  • the present invention has been proposed to solve such a problem.
  • the present invention is characterized in that, in a cover or deck structure of a ship, a beam having a U-shaped or V-shaped cross section is fixed to the back surface of the top plate at predetermined intervals by welding so that an opening surface thereof is in close contact with the top plate. I do.
  • the cross-section forms a box-shaped structure using a U-shaped or V-shaped beam
  • the rigidity and buckling strength of the top plate are increased, and thus the arrangement pitch of the beams can be increased.
  • the welding position is only the portion facing outward, the welding operation is simplified, the welding distortion is correspondingly small, and the post-processing of the distortion removal becomes easy.
  • the beam opening surface is closed, there is no accumulation of particulate matter on the beam, and maintenance such as painting becomes easier.
  • the buckling strength can be effectively improved without increasing the beam spacing density to be arranged.
  • FIG. 1 is a schematic configuration diagram showing one embodiment of the present invention.
  • FIG. 2 is a cross-sectional view of the main part.
  • FIG. 3 is a characteristic diagram showing buckling stress characteristics.
  • FIG. 4 is a sectional view of a conventional example. Preferred embodiment
  • reference numeral 1 denotes a hatch opening
  • a peripheral edge 2 is provided with a hatch cover 3 for opening and closing the opening 1.
  • the hatch cover 3 constitutes, for example, a pair of force bars, and a side rolling type, a bontoon type, etc. are known.
  • the top plate 4 of the hatch cover 3 has a U-shaped or V-shaped beam 5 Are fixed by welding at predetermined pitch intervals in parallel with each other.
  • the U-shaped or V-shaped beam 5 is fixed to each of the legs 5b from the outside by fillet welding with the opening surface 5a in close contact with the top plate 4.

As shown in Fig. 2, the beam interval can be made larger than that of the conventional angle material.
  • Fig. 3 shows the relationship between the magnitude of the stress when the top plate 4 buckles in the direction parallel to its surface and the beam pitch.For a U-shaped or V-shaped beam, It can be seen that buckling is less likely to occur even when the pitch is increased, as compared to the angle material.

Abstract

La présente invention concerne une structure de pont ou de recouvrement pour bateaux. Des poutres (5) ayant une coupe transversale en U ou en V sont soudées et fixées à la surface arrière d'un plateau supérieur (4), à intervalles prédéterminés avec des surfaces ouvertes en contact étroit avec le plateau supérieur (4). Le recouvrement ou le pont présente une rigidité perfectionnée, une distorsion de soudure réduite et une exploitabilité améliorée.
