の貨油の流出防止に有効である。Further, in the present embodiment, since the cargo holds and the peripheral wall surface of the tank have a structure with few protrusions, it is easy to inject and discharge freight oil, seawater ballast, etc., and muddy sand and waste oil pools are reduced. become. In addition, the adoption of the honeycomb panel increases the absorbed energy capacity of the hull structure and reduces the structural stress concentration portions such as the joint portions of the vertical and horizontal members. As a result, the resistance to collision and grounding accidents is improved. Further, since the honeycomb panel has a small double shell, it is effective for preventing the outflow of the oil of coins especially in the case of a slight scratch or minor collision / grounding accident.

されるようになる。As described in detail above, according to the honeycomb panel type hull structure of the present invention, the following effects can be obtained. (1) Since the outer and inner shells of the hull are composed of honeycomb panels that are reinforced in the vertical direction with diagonal members inside, there is no need for many longe materials that were conventionally applied to veneer, and therefore the same. The joint between the longi and the ribs will also disappear. As a result, the productivity of hull construction is improved, and the structural strength and reliability are also improved. Also, the above honeycomb
The joints in the direction perpendicular to the above diagonal members of the panels are
The edges of the diagonal members facing each other of the honeycomb panel,
Weld the same slant member so that it protrudes from each of the sandwiched single plates.
Since it is composed of, honeycomb panel mutual connection work
Will be significantly simplified. (2) Since horizontal reinforcement of the hull is performed not only by horizontal bulkheads but also by ribs, it is not necessary to shorten the mutual spacing of horizontal bulkheads and provide them closely. (3) The horizontal partition wall is composed of a large number of honeycomb panels in which a large number of diagonal members extending in the lateral direction are sandwiched between two single plates and laterally reinforced by the diagonal members. In addition, if a vertical beam is provided to reinforce the horizontal partition wall in the vertical direction, it is not necessary to apply a large number of stiffeners to the horizontal partition wall as a single plate material as in the conventional case. (4) The horizontal partition wall is composed of a large number of honeycomb panels in which a plurality of vertically extending diagonal members are sandwiched between two single plates and vertically reinforced by the diagonal members. In addition, if a horizontal girder is provided to reinforce the horizontal partition wall in the horizontal direction, it is not necessary to apply a large number of stiffeners to the horizontal partition wall as a single plate as in the conventional case. (5) The longitudinal partition wall in the ship is composed of honeycomb panels reinforced by the diagonal members by sandwiching a large number of diagonal members extending in the longitudinal direction between two single plates. In that case, it becomes unnecessary to apply a large number of stiffeners to the vertical partition wall as a single plate material as in the conventional case. (6) According to the above items (3) to (5), the number of protrusions on the surface of each partition wall is reduced, so that it is easy to inject and discharge coin oil, etc.
Waste oil pools will be reduced. (7) A joint portion parallel to the diagonal member of the honeycomb panels, and is formed by fitting and welding the convex edge portion of one honeycomb panel and the concave edge portion of the other honeycomb panel, The connecting work between the honeycomb panels can be easily performed, and when the convex edge portion and the concave edge portion both have a solid structure, the strength of the joint portion can be sufficiently maintained. Like ( 8 ) When a foam material for increasing the strength of the honeycomb panel is filled and solidified in the inside of the honeycomb panel, the strength of the hull made of the honeycomb panel is further improved. ( 9 ) When a gas or a chemical that improves the corrosion resistance of the honeycomb panel is enclosed inside the honeycomb panel,
The life of the hull composed of the same honeycomb panel will be greatly enhanced.
